* erts: Removed unnecessary PCRE source tar-ball.
* ssh: With this change (being response to CVE-2023-48795),
ssh can negotiate "strict KEX" OpenSSH extension with
peers supporting it; also
'chacha20-poly1305@openssh.com' algorithm becomes a
less preferred cipher.
If strict KEX availability cannot be ensured on both
connection sides, affected encryption modes(CHACHA and
CBC) can be disabled with standard ssh configuration.
This will provide protection against vulnerability, but
at a cost of affecting interoperability. See
Configuring algorithms in SSH. (bsc#1218192, CVE-2023-48795)
- Changes for 26.2:
* all: Replaced unintentional Erlang Public License 1.1
headers in some files with the intended Apache License
2.0 header.
* otp: The removal of the deprecated slave module, originally
planned for OTP 27, has been postponed to OTP 29.
* asn1: Fix benign warning from gcc 11 about mismatching call
to free().
* crypto: Enable engine support for OpenSSL versions 3.
* edoc: Emit instead of .
- Disable test suite for now, it has many false positives and
takes a very long time. - Changes for 26.1.2:
* erts: If the external term format encoding of an argument list
part of a distributed spawn operation was faulty, the newly
spawned remote process could misbehave. The misbehavior
included hanging or interpret an incoming message as an
argument list to use. This was very unlikely to happen unless
using an alternate implementation of the distribution protocol
which made a faulty encoding of the argument list. The child
process will now detect this error and terminate before
executing the user specified code.
* erts: Fix bugs where if the body of a matchspec would return a
map with a variable ('$1', '$_' etc) as one of the keys or
values and the variable was not an immidiate, the term would
not be copied to the receiving processes heap. This would later
corrupt the term in the table as the GC could place move
markers in it, which in turn would cause the VM to crash. Bug
has been present for since OTP 17.0.
* xmerl: The xmerl version 1.3.32 was released in OTP 26.0.1, but
the incorrect version number of 1.3.31.1 was used for it. This
incorrect version number continued to appear in OTP 26.0.2, OTP
26.1, and OTP 26.1.1. The actual xmerl code in these OTP
versions however corresponds to xmerl version 1.3.32.
- Changes for 26.1.1:
* wx: The wx application would fail to build on macOS with Xcode
15.
* compiler: The compiler could become extremely slow for modules
containing huge functions.
* stdlib: Garbage collect the shell process when reducing the
amount of saved history and results.
- Changes for 26.1:
* crypto: Fix VM crash caused by crypto being purged and reloaded
(by init:restart for example) on OS with musl libc (such as
Alpine linux).
* crypto: Improved understanding of LibreSSL versions. Support
chacha20 and chacha20_poly1305 for LibreSSL 3.7. Reflect
removal of support for the DSS/DSA algorithm which was done in
LibreSSL 2.6.1.
* crypto: FIPS supported by crypto for OpenSSL 3.0.* and 3.1.*.
* asn1: The ASN.1 compiler would ignore a constraint such as
(SIZE (1..4), ...), causing incorrect behavior of the encoding
and decoding function for the PER and UPER backends. Corrected
to handle the constraint in the same way as (SIZE (1..4, ...)).
* asn1: The JER backend has been internally refactored in a way
that is compatible for applications that use the documented
API. However, for a group of ASN.1 modules that depend on each
other (for example, S1AP-PDU-Descriptions, S1AP-Contents, and
so on), all modules in the group must be recompiled if on of
the group members is recompiled.
* observer: Closing the trace log window via the menu did not
work.
* erts: maps:put with existing key and identical value was not
optimized as a no-op correctly if having the same 32-bit hash
as another key in the map. In practice very rare and harmless.
* erts: Fixed an issue with truncated crash slogans on failed
emulator start.
* erts: Fixed a bug where the emulator was unable to determine
the current cgroup CPU quota.
* erts: A process optimized for parallel signal delivery could
under some circumstances lose wakeup information. That is, the
processes was not woken up to take care of the signal, so the
signal would not be taken care of until the process was woken
by another signal. Only processes configured with
message_queue_data set to off_heap utilize this optimization.
* erts: Function socket:close/1 could cause a VM crash on
Windows.
* erts: Fixed a bug in the ARM JIT where it could accidentally
add garbage trailing bits when creating bitstrings whose size
wasn't an even multiple of 8 bits.
* erts: Fix erlang:system_info/1 documentation to show correct
types.
* erts: Expanded the documentation about how to use the
standard_io, standard_error and user I/O devices. Added the
types io:standard_io/0, io:standard:error/0 and io:user/0.
* erts: Fix compilation with GNU termcap.
* erts: Delivery time of message signals to a process not
executing any receive expressions could become very long,
potentially infinite. For example, a process checking for
messages using process_info(self(), message_queue_len) or
process_info(self(), messages) and avoiding to execute a
receive expression matching on messages could be very slow in
detecting new messages. Note that you are still discouraged
from using process_info() this way. A process that wants to
check if there are messages available to handle should execute
a receive expression matching on messages.
* erts: On AArch64 (ARM64), when calculating both the quotient
and remainder with a divisor begin a power two, the remainder
could be incorrectly calculated.
* erts: Fix bug causing "magic" references in a compressed ETS
table to not keep the referred object alive. The symptom would
be the referred object being garbage collected prematurely and
the reference appearing stale, not referring to anything.
Examples of such magically referred objects are atomics and NIF
resources.
* erts: Matching out short bitstrings with a fixed size not
divisible by 8 could could lead to the runtime system
terminating with an "Overrun heap and stack" error.
* erts: A constant flow of incoming non-message signals could
prevent a process needing to execute dirty from doing so.
* erts: A BEAM file usually contains a chunk with the tag "Type"
containing type information that can be used by the JIT. The
beam_lib:strip/1 takes care to preserve that chunk, but a
build/release tool that does customized stripping could
accidentally remove the chunk. Loading a BEAM file without the
"Type" chunk could cause incorrect behavior of the loaded code.
* erts: gen_udp:recv/* for Unix Domain Socket in binary mode and
passive mode has been fixed to not crash.
* erts: The cleanup operation of not yet delivered signals to a
terminated process yielded excessively.
* erts: Fixed minor hashing issue with the local option of
term_to_binary()/term_to_iovec().
* erts: Update gen_tcp_socket and gen_udp_socket to handle
'completion' (socket on Windows).
* erts: Add support for Unix Domain Sockets (only for STREAM
sockets) on Windows for 'socket'.
* erts: In Erlang/OTP 27, by default escripts will be compiled
before being executed. That means that the compiler application
must be installed. It is possible to force the escript to be
interpreted by adding the directive -mode(interpret). to the
escript file. In Erlang/OTP 28, support for interpreting an
escript will be removed.
* erts: Add basic support for socket ioctl on Windows.
* erts: Removed erts/etc/darwin/Info.plist, as it is no longer
necessary after macos 10.12
* erts: Add support for (Windows) socket option exclusiveaddruse.
* erts: [socket] Add support for the 'nopush' option.
* erts: Add support for socket option 'BSP STATE'.
* erts: Add tcp socket options 'keepcnt', 'keepidle' and
'keepintvl'.
* erts: Add support for misc (Windows) socket options
('max_msg_size' and 'maxdg').
* compiler: The compiler could run forever when compiling a call
to is_record/3 with a huge positive tuple size. The call
is_record(A, a, 0) would crash the compiler when used in a
function body. When used in a guard the compiler would emit
incorrect code that would accept {a> as a record.
* compiler: Fixed a bug that caused dialyzer to crash when
analyzing bogus code that contained the literal atom undefined
in segment sizes.
* compiler: The compiler would crash when compiling some modules
that contained a call to erlang:load_nif/2.
* compiler: Fixed a bug that caused the compiler to crash on
legal code.
* compiler: The compiler could crash when attempting to compile a
call to is_list/1 in a complex expression.
* compiler: A complex guard expression using the or operator
could succeed when it was supposed to fail.
* compiler: Compiling nested try/catch and catch expression could
result in an internal compiler error.
* compiler: Using the bnot operator in a complex expression could
cause the compiler to terminate with an internal consistency
failure diagnostic.
* compiler: Fixed a bug that caused the compiler to crash in a
binary optimization pass.
* compiler: The compiler could terminate with an internal error
when attempting to compile a binary pattern that could not
possibly match.
* compiler: Fixed various performance issues related to the alias
optimization pass.
* erl_docgen: Expanded the documentation about how to use the
standard_io, standard_error and user I/O devices. Added the
types io:standard_io/0, io:standard:error/0 and io:user/0.
* mnesia: Do not delete old backup file if the new backup fails.
* megaco: Make megaco transports handle gen_tcp | gen_udp with
socket backend on Windows (completion).
* common_test: With this change, ct_hooks manual refers to CTH
execution order section in user guide.
* common_test: With this change, Config data from
pre_end_per_testcase hook is delivered to post_end_per_testcase
callback in case of testcase timetrap or linked process crash.
* common_test: With this change, remaining references to not
supported vts tool in ct_run are removed (mainly relates to
docs and ct_run help message).
* common_test: With this change, prompt search functionality in
ct_telnet handles unicode input.
* common_test: Expanded the documentation about how to use the
standard_io, standard_error and user I/O devices. Added the
types io:standard_io/0, io:standard:error/0 and io:user/0.
* stdlib: The compiler could run forever when compiling a call to
is_record/3 with a huge positive tuple size. The call
is_record(A, a, 0) would crash the compiler when used in a
function body. When used in a guard the compiler would emit
incorrect code that would accept {a> as a record.
* stdlib: Fix bug in ets:tab2file that could make it fail if
another Erlang process created the same file at the same time.
* stdlib: An {else_clause,Value} exception will now be reported
nicely in the shell.
* stdlib: Correct return value for error case, so that it matches
the documented and intended return value {error,
{already_started, pid()} when local registered names are used.
* stdlib: sys:get_state/1,2 and sys:replace_state/2,3 has been
corrected to handle a state named error as a state name, not as
a failed system callback. For the standard server behaviours
this was an issue only for gen_statem (and gen_fsm) when the
state name was error, and for gen_server if the complete state
was {error,_}.
* stdlib: Multiple problems were fixed in
filelib:safe_relative_path/2. If its second argument was a path
that contained symbolic links, an incorrect result patch could
be returned. Also, paths were sometimes falsely considered
unsafe.
* stdlib: Fix deadlock when erl.exe is used as part of a pipe on
Windows and trying to set the encoding of the standard_io
device.
* stdlib: Expanded the documentation about how to use the
standard_io, standard_error and user I/O devices. Added the
types io:standard_io/0, io:standard:error/0 and io:user/0.
* stdlib: Fix h/2,3 to properly render multi-clause
documentation.
* stdlib: Timers created by timer:apply_after/4,
apply_interval/4, and apply_repeatedly/4 would silently fail to
do the apply if it was not possible to spawn a process when the
timer expired. This has now been corrected, and if the spawn
fails, the system will be taken down producing a crash dump.
* stdlib: When an Erlang source file lacked a module definition,
there would be a spurious "module name must not be empty"
diagnostic for each spec in the file.
* stdlib: The argument descriptions for option types in argparse
have been made less ambiguous.
* stdlib: Clarified the documentation of normal shutdown reason
on gen_server:call/2,3
* stdlib: Pattern matching and equivalence (=:=, =/=) comparisons
on 0.0 will now raise a warning, as it will no longer be
considered equivalent to -0.0 in OTP 27. If a match on 0.0
specifically is desired (distinct from -0.0), the warning can
be suppressed by writing +0.0 instead. The arithmetic
comparison operators are unaffected, including arithmetic
equality (==). *** POTENTIAL INCOMPATIBILITY ***
* stdlib: The semantics of the gen_{server,statem,event}
behaviour's synchronous start behaviour introduced in OTP-26.0
with OTP-18471, has been clarified in the documentation.
* stdlib: Added functionality to set a custom multiline prompt.

standard_io, standard_error and user I/O devices. Added the
types io:standard_io/0, io:standard:error/0 and io:user/0.

fetch memory used by messages when needed.
* kernel: Fixed a number of socket-related issues causing
incompatibilities with gen_tcp and gen_udp respectively.
* kernel: gen_tcp:connect with socket address and socket (inet-)
backend fails because of missing callback function.
* kernel: The DNS RR cache used by `inet_res` has been fixed to
preserve insert order, which is beneficial when the DNS server
returns RRs in some specific order for e.g load balancing
purposes.
* kernel: The options `reuseport`, `reuseport_lb` and
`exclusiveaddruse` were accidentally not allowed for e.g
`gen_udp:open/1,2`, which has now been corrected.
* kernel: gen_udp:recv/* for Unix Domain Socket in binary mode
and passive mode has been fixed to not crash.
* kernel: Fixed issue where cursor would not be placed at the end
of the expression when navigating shell history.
* kernel: Update gen_tcp_socket and gen_udp_socket to handle
'completion' (socket on Windows).
* kernel: Add support for Unix Domain Sockets (only for STREAM
sockets) on Windows for 'socket'.
* kernel: Add basic support for socket ioctl on Windows.

loading the same module concurrently.
* debugger: The call int:no_break(Module) did not remove any
breakpoints.
* debugger: The maybe expression is now supported in the
Debugger.
* debugger: The maybe expression is now supported in the
Debugger.
* debugger: The call int:no_break(Module) did not remove any
breakpoints.
* ssl: Avoid function clause error in ssl:getopts/2 by handling
that inet:getopts may return an empty list during some
circumstances, such as the socket being in a closing state.
* ssl: The API function `ssl:recv/3` has been tightened to
disallow negative length, which has never been documented to
work, but was passed through and caused strange errors.
* ssl: When a client initiated renegotiation was rejected and the
client socket was in active mode the expected error message to
the controlling process was not sent.
* ssl: Add some guidance for signature algorithms configuration
in ssl applications users guide.
* snmp: Make snmp handle gen_udp with socket backend on Windows
(completion).
* public_key: Country name comparison shall be case insensitive
* public_key: Add check to disallow duplicate certs in a path
* inets: With this change, re_write httpd works as expected and
does not return error.
* inets: Fixed a bug so httpd does not crash when stopped at the
wrong time during TLS connection negotiation, or any other
theoretically as slow connection setup.
* inets: Enhance error handling and avoid that the HTTP client
hangs on headers provided on the wrong format.
* inets: With this change, error report generated by httpd during
connection setup contains socket type information.
* inets: Stop and restart of the httpd server in the Inets
application has been refactored to a more synchronous and OTP
supervisor friendly approach. This should increase stability
and for example avoid a supervisor report from
httpd_connection_sup about killed child process(es) in some
cases when stopping or restarting httpd.
* dialyzer: Fixed a bug that caused dialyzer to crash when
analyzing bogus code that contained the literal atom undefined
in segment sizes.
* dialyzer: Dialyzer could crash when attempting to analyze a
module that defined a type called product/.
- Changes for 26.0.2:
* erts: Fix using the IME (Input Method Editor) to enter text in
cmd.exe and powershell.exe on Windows.
* erts: Multiple socket:accept calls issue. When making multiple
accept calls, only the last call is active.
* erts: Fix the shell to ignore terminal delay when the terminal
capabilities report that they should be used.
* erts: Fix "oldshell" to echo characters while typing on
Windows.
* erts: On Windows, a call to the function socket:close, when
there are waiting active calls to read, write or accept
functions, could hang.
* erts: Fix issues when reading or configuring standard_io on
Windows when erl.exe is started using -noshell flag.
* erts: The following functions are now much faster when given a
long list or binary:
* erts: On AArch64 (ARM64), equality and non-equality tests with
literal bitstrings could succeed when they should fail and vice
versa.
* compiler: Fixed a type handling bug that would cause an
internal consistence failure for correct code.
* compiler: Fixed a bug that could cause the stack trace of throw
exceptions to be erroneously optimized out.
* compiler: Complex guard expression using 'or' were not always
fully evaluated, making guards that were supposed to fail
succeed.
* stdlib: Fix bug where when you entered Alt+Enter in the
terminal, the cursor would move to the last line, instead of
moving to the next line.
* stdlib: Fix eof handling when reading from stdin when erlang is
started using -noshell.
* stdlib: Fixed problem where output would disappear if it was
received after a prompt was written in the shell.
* stdlib: The following functions are now much faster when given
a long list or binary:
* kernel: Fix bug where when you entered Alt+Enter in the
terminal, the cursor would move to the last line, instead of
moving to the next line.
* kernel: Fix so that the shell does not crash on startup when
termcap is not available.
* kernel: Multiple socket:accept calls issue. When making
multiple accept calls, only the last call is active.
* kernel: Fix the shell to ignore terminal delay when the
terminal capabilities report that they should be used.
* kernel: Fix "oldshell" to echo characters while typing on
Windows.
* kernel: Fix eof handling when reading from stdin when erlang is
started using -noshell.
* kernel: On Windows, a call to the function socket:close, when
there are waiting active calls to read, write or accept
functions, could hang.
* kernel: Fix issues when reading or configuring standard_io on
Windows when erl.exe is started using -noshell flag.
* kernel: gen_udp:connect with inet_backend = socket fails when
the Address is a hostname (string or atom).
* kernel: Fixed problem which would cause shell to crash if
particular escape sequence was written to stdout.
* kernel: Fixed problem where output would disappear if it was
received after a prompt was written in the shell.
* kernel: Fix a crash where the location of erts could not be
found in rebar3 dev builds.
* kernel: Introduce the KERNEL application parameter
standard_io_encoding that can be used to set the default
encoding for standard_io. This option needs to be set to latin1
if the application wants to treat all input data as bytes
rather than utf-8 encoded characters.
* ssl: Added keylog information to all protocol versions in
ssl:connection_information/2.
* ssl: Add RFC-6083 considerations for DTLS to enable gen_sctp
based callback for the transport.
* ssh: Added multiline editing support to ssh clients connected
through OTP ssh daemon. - Changes for 26.0.1:
* erts: Build of the socket nif failed on Solaris 11.
* erts: Fixed two reduction-counting bugs relating to binaries.
* erts: Constructing a binary segment not aligned with a byte
boundary, with a size not fitting in 31 bits, and with a value
not fitting in a 64-bit word could crash the runtime system.
* erts: When a binary construction failed because of bad size for
a segment, the error information was not always correct.
* erts: Fixed a crash when calling a fun that was defined in a
module that had been upgraded.
* kernel: The POSIX error exdev was sometimes incorrectly
described as "cross domain link" in some error messages.
* kernel: Corrected the socket send function description (send
with Timeout = nowait). The send function(s) could not return
{ok, {RestData, SelectInfo}}
* stdlib: The POSIX error exdev was sometimes incorrectly
described as "cross domain link" in some error messages.
* ssl: Make sure that selection of client certificates handle
both TLS-1.3 and TLS-1.2 names correctly. Could cause valid
client certificate to not be selected, and an empty client
certificate message to be sent to server.
* ssl: Improved ssl:format_error/1 to handle more error tuples.
* ssl: Fixed hanging ssl:connect when ssl application is not
started.
* ssl: Correct handling of retransmission timers, current
behavior could cause unwanted delays.
* inets: Do not make the default ssl options by calling
httpc:ssl_verify_host_options(true) if ssl options are supplied
by the user.
* xmerl: New options to xmerl_scan and xmerl_sax_parser so one
can limit the behaviour of the parsers to avoid some XML
security issues. xmerl_scan gets one new option:
xmerl_sax_parser gets the following options: The old option
skip_external_dtd is still valid and the same as
{external_entities, none} and {fail_undeclared_ref, false} but
just affects DTD's and not other external references.
* compiler: Fixed a bug where a failing bsl expression in a guard
threw an exception instead of causing the guard to fail.
* compiler: Fixed a bug that would case the validator to reject
legal code.
* compiler: The compiler could re-order clauses matching binaries
so that the incorrect clause would match. That could only
happen for code that used the option {error_location,line} or
for code without line or column number information (e.g.
generated by a parse transform).
* compiler: Complex guard expression using the or operator and
guard BIFs that can fail could sometimes be miscompiled so that
the guard would succeed even if a call to a guard BIF failed.
* compiler: With optimizations disabled, a try/catch construct
could return an incorrect value.
* compiler: In rare circumstance, a combination of binary
construction and binary_part/3 would cause the compiler to
generate unsafe code that would crash the runtime system.
* compiler: The compiler could be very slow when compiling guards
with multiple guard tests separated with 'or' or ';'.
* compiler: Complex guard expressions using 'or' and map updates
could succeed even if the map update failed. - Version 26.0:
* Leex has been extended with optional column number support.
* The family of enumeration functions in module lists has been
extended with enumerate/3 that allows a step value to be
supplied.
* Update Unicode to version 15.0.0.
* proc_lib:start*/* has become synchronous when the started
process fails. This requires that a failing process use a new
function proc_lib:init_fail/2,3, or exits, to indicate failure. All
OTP behaviours have been fixed to do this.
* auto-complete of variables, record names, record fields names,
map keys, function parameter types and filenames.
* Open external editor in the shell to edit the current
expression.
* defining records (with types), functions, specs and types in
the shell.
* Creation and matching of binaries with segments of fixed sizes
have been optimized.
* Creation and matching of UTF-8 segments have been optimized.
* Appending to binaries has been optimized.
* The compiler and JIT now generate better code for creation of
small maps where all keys are literals known at compile time.
* Thanks to the optimizations above the performance of the base64
module has been significantly improved. For example, on an
x86_64 system with the JIT both encode and decode are almost
three times faster than in Erlang/OTP 25.
* Map comprehensions as suggested in EEP 58 has now been
implemented.
* Some map operations have been optimized by changing the
internal sort order of atom keys. This changes the
(undocumented) order of how atom keys in small maps are printed
and returned by maps:to_list/1 and maps:next/1. The new order
is unpredictable and may change between different invocations
of the Erlang VM.
* Introducing the new function maps:iterator/2 for creating an
interator that return the map elements in a deterministic
order. There are also new modifiers k and K for the format
string in io:format() to support printing map elements ordered.
* Added the new built-in type dynamic() introduced in EEP 61, PR
introducing EEP 61 improving support for gradual type checkers.
* Dialyzer has a new incremental mode that be invoked by giving
the --incremental option when running Dialyzer. This new
incremental mode is likely to become the default in a future
release.
* Multi time warp mode is now enabled by default. This assumes
that all code executing on the system is time warp safe.
* Support for UTF-8 atoms and strings in the NIF interface
including new functions enif_make_new_atom,
enif_make_new_atom_len and enif_get_string_length.
* The BIFs min/2 and max/2 are now allowed to be used in guards
and match specs.
* Improved the selective receive optimization, which can now be
enabled for references returned from other functions. This
greatly improves the performance of gen_server:send_request/3,
gen_server:wait_response/2, and similar functions.
* It is no longer necessary to enable a feature in the runtime
system in order to load modules that are using it. It is
sufficient to enable the feature in the compiler when compiling
it.
* inet:setopts/2 has got 3 new options: reuseport, reuseport_lb
and exclusiveaddruse.
* Fix so that -fno-omit-frame-pointer is applied to all of the
Erlang VM when using the JIT so that tools, such as perf, can
crawl the process stacks.
* In the lists module, the zip family of functions now takes
options to allow handling lists of different lengths.
* Added the zip:zip_get_crc32/2 function to retrieve the CRC32
checksum from an opened ZIP archive. gen_server optimized by
caching callback functions
* The modules Erlang DNS resolver inet_res and helper modules
have been updated for RFC6891; to handle OPT RR with DNSSEC OK
(DO) bit.
* Introduced application:get_supervisor/1.
* Cache OTP boot code paths, to limit how many folders that are
being accessed during a module lookup. Can be disabled with
- cache_boot_path false.
* Support for Kernel TLS (kTLS), has been added to the SSL
application, for TLS distribution (-proto_dist inet_tls), the
SSL option {ktls, true}.
* Improved error checking and handling of ssl options.
* Mitigate memory usage from large certificate chains by lowering
the maximum handshake size. This should not effect the common
cases, if needed it can be configured to a higher value.
* For security reasons the SHA1 and DSA algorithms are no longer
among the default values.
* Add encoding and decoding of use_srtp hello extension to
facilitate for DTLS users to implement SRTP functionality. - Changes for 25.3.2.2:
* compiler: The compiler could be very slow when compiling guards
with multiple guard tests separated with 'or' or ';'.
- Changes for 25.3.2.1:
* xmerl: New options to xmerl_scan and xmerl_sax_parser so one
can limit the behaviour of the parsers to avoid some XML
security issues. xmerl_scan gets one new option:
xmerl_sax_parser gets the following options: The old option
skip_external_dtd is still valid and the same as
{external_entities, none} and {fail_undeclared_ref, false} but
just affects DTD's and not other external references.
* erts: Fixed a crash during tracing on certain platforms that
cannot use the machine stack for Erlang code (mainly OpenBSD
and Linux with musl).
* erts: Constructing a binary segment not aligned with a byte
boundary, with a size not fitting in 31 bits, and with a value
not fitting in a 64-bit word could crash the runtime system.
* erts: Further robustify implementation of large maps (> 32
keys). Keys that happen to have same internal 32-bit hash
values are now put in collision nodes which are traversed with
linear search. This removes the demand for the internal hash
function when salted to eventually produce different hashes for
all possible pairs of unequal terms.
* stdlib: Static supervisors are very idle processes after they
have started so they will now be hibernated after start to
improve resource management.
* compiler: Fixed a bug where a failing bsl expression in a guard
threw an exception instead of causing the guard to fail.
* compiler: Complex guard expression using the or operator and
guard BIFs that can fail could sometimes be miscompiled so that
the guard would succeed even if a call to a guard BIF failed. - Changes for 25.3.2:
* compiler: Fixed type handling bugs that could cause an internal
error in the compiler for correct code.
* os_mon: Avoid error report from failing erlang:port_close at
shutdown of cpu_sup and memsup. Bug exists since OTP 25.3
(os_mon-2.8.1).
* erts: If a runtime system which was starting the distribution
already had existing pids, ports, or references referring to a
node with the same nodename/creation pair that the runtime
system was about to use, these already existing pids, ports, or
references would not work as expected in various situations
after the node had gone alive. This could only occur if the
runtime system was communicated such pids, ports, or references
prior to the distribution was started. That is, it was
extremely unlikely to happen unless the distribution was
started dynamically and was even then very unlikely to happen.
The runtime system now checks for already existing pids, ports,
and references with the same nodename/creation pair that it is
about to use. If such are found another creation will be chosen
in order to avoid these issues.
- Changes for 25.3.1:
* snmp: Attempts to minimize the number of the error reports
during a failed agent init.
* compiler: When a map update such as #{}#{key:=value} that
should fail with an exception was unused, the exception would
be lost.
* compiler: Fixed bug in the validator that made it reject valid
code.
* crypto: With this change, random errors are fixed for
crypto:generate_key calls with OpenSSL 3.
* erts: Fixed a bug in the loader that prevented certain modules
compiled with no_ssa_opt from being loaded.
* erts: Implementations of the call() driver callback that
returned a faulty encoded result could cause a memory leak and
could cause invalid data on the heap of the processes calling
erlang:port_call/3.
* erts: Fixed a memory corruption issue when upgrading code. The
bug was introduced in OTP 25.3
* erts: Fixed configure tests for a few ARM-specific
instructions, which prevented the emulator from being built on
some platforms.
* erts: Aliases created in combination with a monitor using the
{alias, explicit_unalias} option stopped working from remote
nodes when a 'DOWN' signal had been received due to the monitor
or if the monitor was removed using the erlang:demonitor() BIF.
This bug was introduced in OTP 24.3.4.10 and OTP 25.3.
* erts: In rare circumstances, bit syntax matching of an invalid
code point for a utf32 would crash the runtime system.
* erts: Building the runtime system failed when native atomic
support was missing. Note that execution on such systems have
only been rudimentary tested.
* erl_interface: Fixed configure tests for a few ARM-specific
instructions, which prevented the emulator from being built on
some platforms.
* eldap: Added a new function eldap:info/1 that returns the
socket and the transport protocol for the eldap connection.
* inets: Correct timing related pipelining/keepalive queue bug,
that could result in unexpected "socket_remotly_closed" errors.
* inets: With this change, upon remote socket closure current
request is added to a retried queue (either pipeline or
keep_alive, but not both).
* ssl: With this change, ssl:connection_information/2 returns
correct keylog data after TLS1.3 key update.
* ssl: Client signature algorithm list input order is now honored
again , it was accidently reversed by a previous fix.
* stdlib: The type specs in the erl_parse module has been updated
to include the maybe construct and the ! operator.
* wx: Improve debug prints from the nifs. Some minor fixes for
wxWidgets-3.2. Fixed OpenGL debug functions. - Changes for 25.3:
* reltool: Fixed a bug that would cause analysis to crash.
* stdlib: Fixed a bug that would cause analysis to crash.
* stdlib: Fixed a crash when formatting stack traces for error
reports.
* stdlib: Instead of crashing, the list_to_integer/1 and
list_to_integer/2 BIFs now raise the system_limit exception for
overlong lists that can't be converted to integers. Similarly,
the string:to_integer/1 BIF now returns {error,system_limit}
for overlong lists.
* stdlib: Removal of non-necessary undefined types added to the
state's supervisor record.
* compiler: Fixed a bug that would cause the compiler to hang.
* compiler: Fixed a crash when compiling code that contained
maybe expressions.
* compiler: Constructing a binary with an explicit size of all
for a binary segment would crash the compiler.
* compiler: The compiler would generate incorrect code for the
following type of expression: Pattern = BoundVar1 = . . . =
BoundVarN = Expression An exception should be raised if any of
the bound variables have different values than Expression. The
compiler would generate code that would cause the bound
variables to be bound to the value of Expressionwhether the
value matched or not.
* xmerl: Replace size/1 with either tuple_size/1 or byte_size/1
The size/1 BIF is not optimized by the JIT, and its use can
result in worse types for Dialyzer. When one knows that the
value being tested must be a tuple, tuple_size/1 should always
be preferred. When one knows that the value being tested must
be a binary, byte_size/1 should be preferred. However,
byte_size/1 also accepts a bitstring (rounding up size to a
whole number of bytes), so one must make sure that the call to
byte_size/ is preceded by a call to is_binary/1 to ensure that
bitstrings are rejected. Note that the compiler removes
redundant calls to is_binary/1, so if one is not sure whether
previous code had made sure that the argument is a binary, it
does not harm to add an is_binary/1 test immediately before the
call to byte_size/1.
* megaco: Replace size/1 with either tuple_size/1 or byte_size/1
The size/1 BIF is not optimized by the JIT, and its use can
result in worse types for Dialyzer. When one knows that the
value being tested must be a tuple, tuple_size/1 should always
be preferred. When one knows that the value being tested must
be a binary, byte_size/1 should be preferred. However,
byte_size/1 also accepts a bitstring (rounding up size to a
whole number of bytes), so one must make sure that the call to
byte_size/ is preceded by a call to is_binary/1 to ensure that
bitstrings are rejected. Note that the compiler removes
redundant calls to is_binary/1, so if one is not sure whether
previous code had made sure that the argument is a binary, it
does not harm to add an is_binary/1 test immediately before the
call to byte_size/1.
* debugger: Fixed a bug that would cause analysis to crash.
* erts: Fixed a bug on Windows where file:read_file_info/1 would
fail for files with corrupt metadata.
* erts: Fix process_info(_, binary) to again include "writable
binaries" which were lost in OTP-25.0. Writable binaries are an
optimization used when binaries are appended upon in a loop.
* erts: Fix rare race when receiving fragmented messages on a
terminating connection. Could potentially cause memory leaks as
well as double free crashes. Bug exists since OTP 22.0.
* erts: Fixed bug that could maybe cause problems when a file
descriptor number is closed by a linked in driver and then
opened (reused) and passed to enif_select by a NIF. No actual
symptoms seen, only failed internal assertions in debug build.
* erts: The runtime system could crash when tracing a process
executing on a dirty scheduler.
* erts: In the binary syntax, attempting to match out integers
with size exceeding 2 GiB could crash the runtime system.
* erts: Fixed edge case in floating-point negation where A = 0.0,
B = -A did not produce B = -0.0 on x86_64 JIT.
* erts: Fixed an issue in the JIT that could crash the emulator
on some platforms.
* erts: Added meta data to the windows installer.
* erts: Fixed ETS insertion order into bag and duplicate_bag of
tuples with identical keys when passed in a list to
ets:insert/2. The insert order has been head-to-tail but was
accidentally changed in OTP 23.0. For bag it was reverted
(tail-to-head), while for duplicate_bag it was sometimes
reverted depending on the length of the list and number of
"reductions" left for the calling process. This fix changes the
insert order of ets:insert/2 back to always be head-to-tail of
the list argument.
* erts: With the JIT for AArch64 (AMD64), calling bxor in with
non-integer arguments in a guard would crash the runtime
system.
* erts: Fix bug regarding process flag max_heap_size. Could cause
strange behavior when a process was killed due to exceeding the
limit.
* erts: Fixed binary comprehensions to be similar to other
creation of binary data with respect to its contribution of
triggering garbage collection.
* erts: In rare circumstances, when a process exceeded its
allowed heap size set by option max_heap_size, it would not be
killed as it should be, but instead enter a kind of zombie
state it would never get out of.
* erts: Instead of crashing, the list_to_integer/1 and
list_to_integer/2 BIFs now raise the system_limit exception for
overlong lists that can't be converted to integers. Similarly,
the string:to_integer/1 BIF now returns {error,system_limit}
for overlong lists.
* erts: Active process aliases of a process at its termination
leaked memory.
* erts: Support for fully asynchronous distributed signaling
where send operations never block. This functionality is by
default disabled and can be enabled per process. For more
information see the documentation of process_flag(async_dist,
Bool).
* erts: Added the +JPperf no_fp option to explicitly disable
Erlang frame pointers otherwise added when using the +JPperf
map option.
* erl_interface: Accept connection setup from OTP 23 and 24 nodes
that are not using epmd.
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation
on the external term format larger than 2 GB cannot be handled.
* syntax_tools: erl_syntax_lib:annotate_bindings/1,2 will now
properly annotate named functions and their arguments.
* kernel: Fixed a bug on Windows where file:read_file_info/1
would fail for files with corrupt metadata.
* kernel: Accept connection setup from OTP 23 and 24 nodes that
are not using epmd.
* public_key: As different solutions of verifying certificate
revocation exists move the decode of 'CRLDistributionPoints' so
that it will only be decode. When it is actually used in the
verification process. This would enable interoperability with
systems that use certificates with an invalid empty
CRLDistributionPoints extension that they want to ignore and
make verification by other means.
* public_key: public_key:pkix_path_validation validates
certificates expiring after 2050
* public_key: Do not leave exit message in message queue after
calling cacerts_load() on MacOS.
* public_key: Replace size/1 with either tuple_size/1 or
byte_size/1 The size/1 BIF is not optimized by the JIT, and its
use can result in worse types for Dialyzer. When one knows that
the value being tested must be a tuple, tuple_size/1 should
always be preferred. When one knows that the value being tested
must be a binary, byte_size/1 should be preferred. However,
byte_size/1 also accepts a bitstring (rounding up size to a
whole number of bytes), so one must make sure that the call to
byte_size/ is preceded by a call to is_binary/1 to ensure that
bitstrings are rejected. Note that the compiler removes
redundant calls to is_binary/1, so if one is not sure whether
previous code had made sure that the argument is a binary, it
does not harm to add an is_binary/1 test immediately before the
call to byte_size/1.
* ssl: Fixed that new dtls connections from the same client ip
port combination works. If there is a process waiting for
accept the new connection will connect to that, otherwise it
will try to re-connect to the old server connection.
* ssl: When shutting down a node that uses SSL distribution
(-proto_dist inet_tls), a confusing error message about an
unexpected process exit was printed. This particular message is
no longer generated.

* jinterface: Accept connection setup from OTP 23 and 24 nodes
that are not using epmd.
* os_mon: The port programs used by cpu_sup and memsup are now
gracefully shut down when cpu_sup and memsup are shut down.

* crypto: A user defined runtime library path configured using
- -with-ssl-rpath= could fail to be enabled.
* crypto: Ensure that configure fails if a user defined runtime
library path has been passed by the user, but cannot set.
* mnesia: Improved consistency for dirty writes when a table was
added with add_table_copy/3. Fixed a problem with sticky write,
which could lead to inconsistent data.

* inets: With this change, handling of URI to a folder, with
missing trailing / and a query component present is fixed.
* inets: Adds more type information to the inets app, thus
improving the errors that static analysis tools can detect. The
addition of type information to records and the updates to
function heads help static analysis tools to understand that
some values in the records cannot be 'undefined', thus making
static tools to type check correctly more modules in the inets

- Changes for 25.2.3:
* erts: Comparisons between small numbers and pids or ports would
in some edge cases say that the number was greater than the pid
or port, violating the term order.
* erts: process_info(Pid, status) when Pid /= self() could return
an erroneous result.
* ssl: Maximize compatibility by ignoring change_cipher_spec
during handshake even if middle_box_mode is not negotiated
(mandated by client)
* ssl: Move assert of middlebox message after an
hello_retry_request to maximize interoperability. Does not
changes semantics of the protocol only allows unexpected
message delay from server.
* ssh: With this change, ssh application does not crash when
formatting some of info reports for unsuccessful connections.
* ssh: With this change, ssh does not log extensively long
messages.
* inets: Ensure graceful shutdown
* inets: Return type of the type specification for function
httpc:cookie_header/{1,2,3} has been fixed from -spec
cookie_header(url()) -> [{ field(), value() }] | {error,
Reason} to -spec cookie_header(url()) -> { field(), value() } |
{error, Reason}
- Changes for 25.2.2:
* ftp: Fixes calls to ftp:nlist/2 returning {error, epath} when
the file / folder exists
- Changes for 25.2.1:
* compiler: Fixed a bug that could cause legal code to fail
validation.
* compiler: Eliminated a rare crash in the beam_types module.
* erts: Fixed a bug in selective receive optimization that could
crash 32-bit emulators.
* erts: A race condition which was very rarely triggered could
cause the signal queue of a process to become inconsistent
causing the runtime system to crash.
* kernel: The tcp connect option 'bind_to_device' could not be
used with inet_backend = 'socket'. 'inet' requires value type
binarry() and 'socket' requires value type 'string()'.
* kernel: Minor issue processing options when calling
gen_tcp:connect with a sockaddr() and inet_backend = socket.
* common_test: Change timeout to infinity for gen_server calls in
cth_log_redirect
* inets: fixes a missing case of the type specification for
httpd:info/2/3/4
* snmp: Single threaded agent crash when vacm table not properly
initiated. - Changes for 25.2:
* erts: Fix perf/gdb JIT symbols to not contain CodeInfoPrologue
for the JIT internal module erts_beamasm.
* erts: Fixed minor memory leaks.
* erts: Fix bugs in ets:insert and ets:insert_new when called
with a list of tuples to insert while a concurrent process
either deletes or renames the table. The table deletion could
be done with ets:delete/1 or be caused by termination of the
table owning process. Symptoms are either VM crash or strange
incorrect behavior from the insert operation. The risk of
triggering the bugs increases with the length of the list of
tuple to insert. Bugs exist since OTP 23.0.
* erts: Boost execution of scheduled thread progress jobs. This
to prevent memory exhaustion in extremely rapid
allocation/deallocation scenarios, such as repeated ETS table
creations/deletions.
* erts: Fix segv crash during crash dumping an ETS table doing
ets:delete_all_objects.
* erts: Spec for function net:if_names/0 incorrect
* erts: Fix bug in binary_to_term decoding a binary term 2Gbyte
or larger.
* erts: Documentation of erlang:module_loaded/1 has been
adjusted:
* erts: Fix list_to_atom/1 for negative code points. Could either
return with a positive code point or fail with an incorrect
exception.
* erts: Fix rare bug causing VM crash when sending to a pid of a
spawning process returned from erlang:processes/0. Only seen
when provoked by system process literal_area_collector,
triggered by a module purge operation, on a VM started with
+Meamin (no customized allocators).
* erts: gen_udp:open/2 with option(s) add_membership or
drop_membership would drop earlier options.
* erts: The inet:setopts/2 {reuseaddr, true} option will now be
ignored on Windows unless the socket is an UDP socket. For more
information see the documentation of the reuseaddr option part
of the documentation of inet:setopts/2. Prior to OTP 25 the
{reuseaddr, true} option was ignored for all sockets on
Windows, but as of OTP 25.0 this was changed so that it was not
ignored for any sockets. *** POTENTIAL INCOMPATIBILITY ***
* erts: Fix bug in binary_to_term decoding a list of length 1G or
longer.
* erts: Fix bug in binary_to_term (and distributed receive) when
decoding a large map (>32 keys) with unsorted small maps (<=
32) as keys of the large map. This was only a problem if the
term was encoded by erl_interface, jinterface or otherwise, as
the VM itself always encodes small maps with sorted keys. The
"binary_to_term" would appear as successful but the created
large map was internally inconsistent. The smaller key-maps
could not be found with maps:get and friends. Other operations
such as map compare and merge could probably also give
incorrect results.
* erts: Fix Windows bug in open_port({spawn, Command}, ..) when
Command is found via the OS search PATH and that directory path
contains white spaces. The port program would start but the
command line arguments to it could be incorrect.
* ftp: fix unexpected result ok when calling ftp:nlist repeatedly
* inets: This change allows body requests to httpc:request/5 be
an iolist()
* inets: addition of type specs in httpc.erl
* inets: httpc: Add support for HTTP 308 status code
* dialyzer: Dialyzer would crash when attempting to analyze a bit
syntax segment size having an literal non-integer size such as
[].
* dialyzer: Dialyzer could crash when trying to analyze a
convoluted nested expression involving funs,
* kernel: Fixed shutdown crash in gen_tcp socket backend, when
the other end closed the socket.
* kernel: erl_tar can now read gzip-compressed tar files that are
padded. There is a new option compressed_one for file:open/2
that will read a single member from a gzip file,
* kernel: Fix os:cmd to not translate all exceptions thrown to
badarg. For example emfile from erlang:open_port was translated
to badarg. This bug has existed since Erlang/OTP 24.
* kernel: Spec for function net:if_names/0 incorrect
* kernel: Missing ctrl option name transation for TOS and TTL (on
FreeBSD) when using gen_udp with the 'socket' inet_backend.
* kernel: gen_udp:open/2 with option(s) add_membership or
drop_membership would drop earlier options.
* kernel: The inet:setopts/2 {reuseaddr, true} option will now be
ignored on Windows unless the socket is an UDP socket. For more
information see the documentation of the reuseaddr option part
of the documentation of inet:setopts/2. Prior to OTP 25 the
{reuseaddr, true} option was ignored for all sockets on
Windows, but as of OTP 25.0 this was changed so that it was not
ignored for any sockets. *** POTENTIAL INCOMPATIBILITY ***
* kernel: The distribution socket option handling in
inet_tcp_dist has been cleaned up to clarify which were
mandatory and which just had default values.
* kernel: Improve warning message format for gen_tcp_socket.
* snmp: Explicitly close the socket(s) when terminating
(default-) net-if process.
* stdlib: erl_tar can now read gzip-compressed tar files that are
padded. There is a new option compressed_one for file:open/2
that will read a single member from a gzip file,
* stdlib: A concurrent call to ets:rename could cause
ets:delete_all_objects to fail halfway through with badarg.
* stdlib: It is not allowed to call functions from guards. The
compiler failed to reject a call in a guard when done by
constructing a record with a default initialization expression
that called a function.
* stdlib: The compiler could crash when using a record with
complex field initialization expression as a filter in a list
comprehension.
* stdlib: unicode:characters_to_binary() could build
unnecessarily large call stack.
* stdlib: Improve error message for ets:new/2 name clash. Say
"name already exists" instead of less specific "invalid
options".
* mnesia: Fixed crash which could happen during startup if too
many decisions where sent from remote nodes.
* os_mon: The disk_space_check_interval configuration parameter
of disksup can now be set to values smaller than a minute.
* ssh: graceful shutdown of ssh_conection_handler when connection
is closed by peer
* common_test: Fix starting of peer nodes on old releases when
the compile server was active and the current Erlang
installation contained non-latin1 characters in its path.
* public_key: Disregard LDAP URIs when HTTP URIs are expected.
* ssl: With this change, tls_sender process is hibernated after
sufficient inactivity.
* ssl: Correct handling of legacy schemes so that ECDSA certs
using sha1 may be used for some TLS-1.3 configurations.
* ssl: With this change, tls_sender does not cause logger crash
upon key update.
* ssl: Enhance warning message
* ssl: Provide server option to make certificate_authorities
extension in the TLS-1.3 servers certificate request optional.
This will allow clients to send incomplete chains that may be
reconstructable and thereby verifiable by the server, but that
would not adhere to the certificate_authorities extension.
* ssl: If the verify_fun handles four arguments the DER cert will
be supplied as one of the arguments.
* megaco: A very minor improvement to the measurement tool.
* observer: A WX event race could causes a crash in when handling
socket or port info.
* observer: Improve the nodes menu to include more nodes.
* compiler: Line number in compiler messages would be truncated
to 4 digits for line numbers greater than 9999.
* compiler: In rare circumstance, matching a binary as part of a
receive clause could cause the compiler to terminate because of
an internal consistency check failure.
* compiler: Compiling a function with complex bit syntax matching
such as f(<>, <>) -> ok. could crash the
compiler.
* compiler: It is not allowed to call functions from guards. The
compiler failed to reject a call in a guard when done by
constructing a record with a default initialization expression
that called a function.
* compiler: The compiler could crash when using a record with
complex field initialization expression as a filter in a list
comprehension.
* wx: Added environment variable WX_MACOS_NON_GUI_APP to allow
user to override OSXIsGUIApplication behavior. - Changes for 25.1.2:
* mnesia: Don't fill the logs if mnesia can't connect to all
nodes, due to partitioned network.
* erts: Add abandon carrier free utilization limit (+Muacful)
option to erts_alloc. This option allows the user to mark
unused segments in a memory carrier as re-useable by the OS if
needed. This functionality was a non-configurable default
before Erlang/OTP 25, but removed due to performance issues. - Changes for 25.1.1:
* dialyzer: Dialyzer could crash when analyzing Elixir code that
used intricate macros.
* dialyzer: The --input_list_file option has been added.
* ssl: Fixes handling of symlinks in cacertfile option.
* eunit: With this change, eunit exact_execution option works
with application primitive.
* stdlib: peer nodes failed to halt when the process supervising
the control connection crashed. When an alternative control
connection was used, this supervision process also quite
frequently crashed when the peer node was stopped by the node
that started it which caused the peer node to linger without
ever halting.
* asn1: For the per and uper ASN.1 encoding rules, encoding and
decoding the SEQUENCE OF and SET OF constructs with 16384 items
or more is now supported.
* erts: Listen sockets created with the socket module, leaked
(erlang-) monitors.
* erts: Notifications about available distribution data sent to
distribution controller processes could be lost. Distribution
controller processes can be used when implementing an
alternative distribution carrier. The default distribution over
tcp was not effected and the bug was also not present on
x86/x86_64 platforms.
* kernel: Listen sockets created with the socket module, leaked
(erlang-) monitors.
* kernel: peer nodes failed to halt when the process supervising
the control connection crashed. When an alternative control
connection was used, this supervision process also quite
frequently crashed when the peer node was stopped by the node
that started it which caused the peer node to linger without
ever halting.
- Changes for 25.1:
* dialyzer: Two bugs have been fixed in Dialyzer's checking of
behaviors: When a mandatory callback function is present but
not exported, Dialyzer would not complain about a missing
callback. When an optional callback function was not exported
and had incompatible arguments and/or the return values were
incompatible, Dialyzer would complain. This has been changed to
suppress the warning, because the function might not be
intended to be a callback function, for instance if a release
added a new optional callback function (such as format_status/1
for the gen_server behaviour added in OTP 25).
* dialyzer: The no_extra_return and no_missing_return warnings
can now be suppressed through -dialyzer directives in source
code.
* jinterface: Fix javadoc build error by adding option -encoding
UTF-8.
* diameter: There is a new configure option, --enable-
deterministic-build, which will apply the deterministic
compiler option when building Erlang/OTP. The deterministic
option has been improved to eliminate more sources of non-
determinism in several applications.
* crypto: Fix configure with --with-ssl and --disable-dynamic-
ssl-lib on Windows.
* crypto: Remove all references correctly in the garbage
collection if an engine handle was not explicit unloaded.
* crypto: Changed the behaviour of the engine load/unload
functions The engine load/unload functions have got changed
semantics to get a more consistent behaviour and work correct
when variables are garbage collected. The load functions now
don't register the methods for the engine to replace. That will
now be handled with the new functions
engine_register/engine_unregister if needed. Some functions are
removed from the documentation and therefor the API, but they
are left in the code for compatibility. *** POTENTIAL
INCOMPATIBILITY ***
* crypto: Fixed a naming bug for AES-CFB and Blowfish-CFB/OFB
when linked with OpenSSL 3.0 cryptolib.
* crypto: Sign/verify does now behave as in OTP-24 and earlier
for eddsa.
* crypto: Pass elliptic curve names from crypto.erl to crypto's
nif.
* crypto: The configure option --disable-deprecated-warnings is
removed. It was used for some releases when the support for
OpenSSL 3.0 was not completed. It is not needed in OTP 25.
* crypto: Crypto is now considered to be usable with the OpenSSL
3.0 cryptolib for production code. ENGINE and FIPS are not yet
fully functional.
* crypto: Do not exit if the legacy provider is missing in
libcrypto 3.0.
* ssl: Reject unexpected application data in all relevant places
for all TLS versions. Also, handle TLS-1.3 middlebox
compatibility with more care. This will make malicious
connections fail early and further, mitigate possible DoS
attacks, that would be caught by the handshake timeout. Thanks
to Aina Toky Rasoamanana and Olivier Levillain from Télécom
SudParis for alerting us of the issues in our implementation.
* ssl: With this change, value of cacertfile option will be
adjusted before loading certs from the file. Adjustments
include converting relative paths to absolute and converting
symlinks to actual file path. Thanks to Marcus Johansson
* ssl: In TLS-1.3, if chain certs are missing (so server auth
domain adherence can not be determined) send peer cert and hope
the server is able to recreate a chain in its auth domain.
* ssl: Make sure periodical refresh of CA certificate files
repopulates cache properly.
* ssl: Correct internal CRL cache functions to use internal
format consistently.
* ssl: Incorrect handling of client middlebox negotiation for
TLS-1.3 could result in that a TLS-1.3 server would not use
middlebox mode although the client was expecting it too and
failing the negotiation with unexpected message.
* ssl: If the "User" process, the process starting the TLS
connection, gets killed in the middle of spawning the dynamic
connection tree make sure we do not leave any processes behind.
* ssl: A vulnerability has been discovered and corrected. It is
registered as CVE-2022-37026 "Client Authentication Bypass".
Corrections have been released on the supported tracks with
patches 23.3.4.15, 24.3.4.2, and 25.0.2. The vulnerability
might also exist in older OTP versions. We recommend that
impacted users upgrade to one of these versions or later on the
respective tracks. OTP 25.1 would be an even better choice.
Impacted are those who are running an ssl/tls/dtls server using
the ssl application either directly or indirectly via other
applications. For example via inets (httpd), cowboy, etc. Note
that the vulnerability only affects servers that request client
certification, that is sets the option {verify, verify_peer}.
(bsc#1205318)
* eunit: With this change, Eunit can optionally not try to
execute related module with "_tests" suffix. This might be used
for avoiding duplicated executions when source and test modules
are located in the same folder.
* erl_docgen: Update DTD to allow XML tag em under pre.
* inets: Add httpc:ssl_verify_host_options/1 to help setting
default ssl options for the https client.
* inets: This change fixes dialyzer warnings generated for
inets/httpd examples (includes needed adjustment of spec for
ssh_sftp module).
* inets: Remove documentation of no longer supported callback.
* stdlib: Fixed inconsistency bugs in global due to
nodeup/nodedown messages not being delivered before/after
traffic over connections. Also fixed various other
inconsistency bugs and deadlocks in both global_group and
global. As building blocks for these fixes, a new BIF
erlang:nodes/2 has been introduced and
net_kernel:monitor_nodes/2 has been extended. The -hidden and
- connect_all command line arguments did not work if multiple
instances were present on the command line which has been
fixed. The new kernel parameter connect_all has also been
introduced in order to replace the -connect_all command line
argument.
* stdlib: Fix the public_key:ssh* functions to be listed under
the correct release in the Removed Functionality User's Guide.
* stdlib: The type spec for format_status/1 in gen_statem,
gen_server and gen_event has been corrected to state that the
return value is of the same type as the argument (instead of
the same value as the argument).
* stdlib: If the timer server child spec was already present in
kernel_sup but it was not started, the timer server would fail
to start with an {error, already_present} error instead of
restarting the server.
* stdlib: When changing callback module in gen_statem the
state_enter calls flag from the old module was used in for the
first event in the new module, which could confuse the new
module and cause malfunction. This bug has been corrected. With
this change some sys debug message formats have been modified,
which can be a problem for debug code relying on the format.
* ** POTENTIAL INCOMPATIBILITY ***
* stdlib: There is a new configure option, --enable-
deterministic-build, which will apply the deterministic
compiler option when building Erlang/OTP. The deterministic
option has been improved to eliminate more sources of non-
determinism in several applications.
* stdlib: The rfc339_to_system_time/1,2 functions now allows the
minutes part to be omitted from the time zone.
* stdlib: The receive statement in gen_event has been optimized
to not use selective receive (which was never needed, and could
cause severe performance degradation under heavy load).
* stdlib: Add new API function erl_features:configurable/0
* parsetools: There is a new configure option, --enable-
deterministic-build, which will apply the deterministic
compiler option when building Erlang/OTP. The deterministic
option has been improved to eliminate more sources of non-

* public_key: Support more Linux distributions in cacerts_load/0.
* public_key: Correct asn1 typenames available in type
pki_asn1_type()
* public_key: Sign/verify does now behave as in OTP-24 and
earlier for eddsa.
* snmp: Improved the get-bulk response max size calculation. Its
now possible to configure 'empty pdu size', see appendix c for
more info.
* snmp: Fix various example dialyzer issues
* ssh: Handling rare race condition at channel close.
* ssh: New ssh option no_auth_needed to skip the ssh
authentication. Use with caution!
* ssh: This change fixes dialyzer warnings generated for
inets/httpd examples (includes needed adjustment of spec for
ssh_sftp module).
* ssh: The new function ssh:daemon_replace_options/2 makes it
possible to change the Options in a running SSH server.
Established connections are not affected, only those created
after the call to this new function.
* ssh: Add a timeout as option max_initial_idle_time. It closes a
connection that does not allocate a channel within the timeout
time. For more information about timeouts, see the Timeouts
section in the User's Guide Hardening chapter.
* observer: Fixed units in gui.
* xmerl: There is a new configure option, --enable-deterministic-
build, which will apply the deterministic compiler option when
building Erlang/OTP. The deterministic option has been improved
to eliminate more sources of non-determinism in several
applications.
* asn1: There is a new configure option, --enable-deterministic-
build, which will apply the deterministic compiler option when
building Erlang/OTP. The deterministic option has been improved
to eliminate more sources of non-determinism in several
applications.
* erts: Fixed inconsistency bugs in global due to nodeup/nodedown
messages not being delivered before/after traffic over
connections. Also fixed various other inconsistency bugs and
deadlocks in both global_group and global. As building blocks
for these fixes, a new BIF erlang:nodes/2 has been introduced
and net_kernel:monitor_nodes/2 has been extended. The -hidden
and -connect_all command line arguments did not work if
multiple instances were present on the command line which has
been fixed. The new kernel parameter connect_all has also been
introduced in order to replace the -connect_all command line
argument.
* erts: Fixed IPv6 multicast_if and membership socket options.
* erts: Accept funs (NEW_FUN_EXT) with incorrectly encoded size
field. This is a workaround for a bug (OTP-18104) existing in
OTP 23 and 24 that could cause incorrect size fields in certain
cases. The emulator does not use the decoded size field, but
erl_interface still does and is not helped by this workaround.
* erts: Fixed issue with inet:getifaddrs hanging on pure IPv6
Windows
* erts: Fix faulty distribution encoding of terms with either The
symptom could be failed decoding on the receiving side leading
to aborted connection. Fix OTP-18093 is a workaround for theses
bugs that makes the VM accepts such faulty encoded funs. The
first encoding bug toward pending connection exists only in OTP
23 and 24, but the second one exists also on OTP 25.
* erts: Fixed emulator crash that could happen during crashdump
generation of ETS tables with options ordered_set and
{write_concurrency,true}.
* erts: Retrieval of monotonic and system clock resolution on
MacOS could cause a crash and/or erroneous results.
* erts: Fix bug where the max allowed size of erl +hmax was lower
than what was allowed by process_flag.
* erts: On computers with ARM64 (AArch64) processors, the JIT
could generate incorrect code when more than 4095 bits were
skipped at the tail end of a binary match.
* erts: In rare circumstances, an is_binary/1 guard test could
succeed when given a large integer.
* erts: Fix bug causing ets:info (and sometimes ets:whereis) to
return 'undefined' for an existing table if a concurrent
process were doing ets:insert with a long list on the same
table.
* erts: Fix writing and reading of more than 2 GB in a single
read/write operation on macOS. Before this fix attempting to
read/write more than 2GB would result in {error,einval}.
* erts: Fix bug sometimes causing emulator crash at node shutdown
when there are pending connections. Only seen when running duel
distribution protocols, inet_drv and inet_tls_dist.
* erts: Yield when adjusting large process message queues due to
The message queue adjustment work will now be interleaved with
all other types of work that processes have to do, even other
message queue adjustment work.
* erts: Add rudimentary debug feature (option) for the inet-
driver based sockets, such as gen_tcp and gen_udp.
* erts: Introduced the hidden and dist_listen options to
net_kernel:start/2. Also documented the -dist_listen command
line argument which was erroneously documented as a kernel
parameter and not as a command line argument.
* erts: New documentation chapter "Debugging NIFs and Port
Drivers" under Interoperability Tutorial.
* erts: Add new API function erl_features:configurable/0
* kernel: Fixed inconsistency bugs in global due to
nodeup/nodedown messages not being delivered before/after
traffic over connections. Also fixed various other
inconsistency bugs and deadlocks in both global_group and
global. As building blocks for these fixes, a new BIF
erlang:nodes/2 has been introduced and
net_kernel:monitor_nodes/2 has been extended. The -hidden and
- connect_all command line arguments did not work if multiple
instances were present on the command line which has been
fixed. The new kernel parameter connect_all has also been
introduced in order to replace the -connect_all command line
argument.
* kernel: Fixed IPv6 multicast_if and membership socket options.
* kernel: Fixed issue with inet:getifaddrs hanging on pure IPv6
Windows
* kernel: The type specifications for inet:getopts/2 and
inet:setopts/2 have been corrected regarding SCTP options.
* kernel: The type specifications for inet:parse_* have been
tightened.
* kernel: Fix gen_tcp:connect/3 spec to include the inet_backend
option.
* kernel: Fix bug where using a binary as the format when calling
logger:log(Level, Format, Args) (or any other logging function)
would cause a crash or incorrect logging.
* kernel: Add rudimentary debug feature (option) for the inet-
driver based sockets, such as gen_tcp and gen_udp.
* kernel: Introduced the hidden and dist_listen options to
net_kernel:start/2. Also documented the -dist_listen command
line argument which was erroneously documented as a kernel
parameter and not as a command line argument.
* kernel: Scope and group monitoring have been introduced in pg.
For more information see the documentation of
pg:monitor_scope(), pg:monitor(), and pg:demonitor().
* kernel: A new function global:disconnect/0 has been introduced
with which one can cleanly disconnect a node from all other
nodes in a cluster of global nodes.
* compiler: The compiler will now forbid using the empty atom ''
as module name. Also forbidden are modules names containing
control characters, and module names containing only spaces and
soft hyphens.
* compiler: The bin_opt_info and recv_opt_info options would
cause the compiler to crash when attempting to compile
generated code without location information.
* compiler: In rare circumstances involving floating point
operations, the compiler could terminate with an internal
consistency check failure.
* compiler: In rare circumstances when doing arithmetic
instructions on non-numbers, the compiler could crash.
* compiler: In rare circumstances, complex boolean expressions in
nested cases could cause the compiler to crash.
* compiler: Expression similar to #{assoc:=V} = #key=>self()}, V
would return the empty map instead of raising an exception.
* compiler: Eliminated a crash in the beam_ssa_bool pass of the
compiler when compiling a complex guard expression.
* compiler: In rare circumstances, the compiler could crash with
an internal consistency check failure.
* compiler: When compiling with the option inline_list_funcs, the
compiler could produce a nonsensical warning.
* compiler: When given the no_ssa_opt option, the compiler could
terminate with an internal consistency failure diagnostic when
compiling map matching.
* compiler: Made warnings for existing atoms being keywords in
experimental features more precise, by not warning about quoted
atoms.
* compiler: There is a new configure option, --enable-
deterministic-build, which will apply the deterministic
compiler option when building Erlang/OTP. The deterministic
option has been improved to eliminate more sources of non-
determinism in several applications.
* megaco: Fixed various dialyzer related issues in the examples
and the application proper.
* megaco: There is a new configure option, --enable-
deterministic-build, which will apply the deterministic
compiler option when building Erlang/OTP. The deterministic
option has been improved to eliminate more sources of non-
determinism in several applications.
* common_test: Fix cth_surefire to handle when a suite is not
compiled with debug_info. This bug has been present since
Erlang/OTP 25.0.
* common_test: Common Test now preserves stack traces for throws. - Changes for 25.0.4:
* kernel: A call to net_kernel:setopts(new, Opts) at the same
time as a connection was being set up could cause a deadlock
between the net_kernel process and the process setting up the
connection.
* erts: The monitor/3 BIF did not apply options to the created
monitor if the target process or port did not exist. That is,
the corresponding down message would get a `DOWN` tag even if a
custom tag had been set, and the returned reference was not an
alias even if the alias option had been passed.
* erts: The erlang:monotonic_time/1, erlang:system_time/1,
erlang:time_offset/1, and os:system_time/1 BIFs erroneously
failed when passed the argument native. - Changes for 25.0.3:
* erts: Distributed exit signals could be lost under the
following conditions:
* erts: A race could cause process_info(Pid, message_queue_len)
on other processes to return invalid results.
* erts: Fixed reduction counting for handling process system
tasks.
* erts: Priority elevation of terminating processes did not work
which could cause execution of such processes to be delayed.
* erts: An unlink operation made by a process that terminated
before the unlink operation completed, i.e., before it had
received an unlink-ack signal from the linked process, caused
an exit signal to erroneously be sent from the terminating
process to the process being unlinked. This exit signal would
most often be ignored by the receiver, but if the receiver of
the exit signal concurrently set up a new link, it could
receive the exit signal with the actual exit reason of the
terminating process instead of a noproc exit reason. It is
however very hard to detect that this has happened and has no
obvious negative consequences, so it should be considered
harmless. A distributed unlink-ack signal received by a
terminating process was also not properly removed which could
cause a minor memory leak.
* ssl: The link to crypto:engine_load refered the function with
wrong arity. - Changes for 25.0.2:
* ssl: Improved handling of unexpected messages during the
handshake, taking the right action for unexpected messages.
* erts: On computers with the ARM64 (AArch64) architecture (such
as Apple Silicon Macs) a rem expression followed by a div
expression with the same operands could evaluate to the wrong
result if the result of the rem expression was unused.
- Changes for 25.0.1:
* ssl: When a TLS-1.3 enabled client tried to talk to a TLS-1.2
server that coalesces TLS-1.2 handshake message over one TLS
record, the connection could fail due to some message being
handled in the wrong state, this has been fixed.
* ssl: Correctly handles supported protocol version change from
default to something else by sni_fun supplied to
ssl:handshake/[2,3] together with a TCP-socket (so called
upgrade).
* ssl: Also, TLS-1.3 should respond with a protocol version alert
if previous versions, that are supported but not configured,
are attempted.
* kernel: The DNS resolver inet_res has been fixed to ignore
trailing dot difference in the request domain between the sent
request and the received response, when validating a response.
* kernel: A bug in inet_res has been fixed where a missing
internal {ok,_} wrapper caused inet_res:resolve/* to return a
calculated host name instead of an `{ok,Msg} tuple, when
resolving an IP address or a host name that is an IP address
string.
* kernel: The erlang:is_alive() BIF could return true before
configured distribution service was available. This bug was
introduced in OTP 25.0 ERTS version 13.0. The
erlang:monitor_node() and erlang:monitor() BIFs could
erroneously fail even though configured distribution service
was available. This occurred if these BIFs were called after
the distribution had been started using dynamic node name
assignment but before the name had been assigned.
* kernel: Added the missing mandatory address/0 callback in the
gen_tcp_dist example.
* erts: A spawn_reply signal from a remote node could be delayed
and be delivered after other signals from the newly spawned
process. When this bug triggered, the connection to the node
where the process was spawned sometimes could be taken down due
to the bug. The following error message would then be logged if
this happened: Missing 'spawn_reply' signal from the node
detected by on the node . The
node probably suffers from the bug with ticket id
OTP-17737. This bug only affected processes which had enabled
off_heap message_queue_data and parallel reception of signals
had been automatically enabled. This bug was introduced in OTP
25.0, ERTS version 13.0.
* erts: Fixed type spec of erlang:system_info(dist_ctrl).
* erts: The zlib built in to the runtime system has been updated
to version 1.2.12. (Note that on most platforms, the platform's
own zlib is used.)
* erts: The erlang:is_alive() BIF could return true before
configured distribution service was available. This bug was
introduced in OTP 25.0 ERTS version 13.0. The
erlang:monitor_node() and erlang:monitor() BIFs could
erroneously fail even though configured distribution service
was available. This occurred if these BIFs were called after
the distribution had been started using dynamic node name
assignment but before the name had been assigned.
* crypto: Note in the documentation that MODP (rfc3526) groups
and OpenSSL 3.0 can give an error if a call to
crypto:generate_key/2 specifies a key length, and that length
is to small.
* crypto: The cmac now uses only the 3.0 API
* crypto: Documentation is now updated with which OpenSSL
cryptolib versions that OTP currently is tested.
* dialyzer: Fixed the documentation for the missing_return and
extra_return options.
* mnesia: Fixed add_table_copy which could leave a table lock if
the receiving node went down during the operation.
* ssh: Binaries can be limited in logs with the parameter
max_log_item_len. The default value is 500 bytes.
* stdlib: In the initial release of Erlang/OTP 25, the expression
bound to the _ pseudo-field in a record initialization would
always be evaluated once, even if all other fields in the
record were explicitly initialized. That would break the use
case of binding the expression error(...) to _ in order to get
an exception if not all fields were initialized. The behavior
of binding to _ has been reverted to the pre-OTP 25 behavior,
that is, to not evaluate the expression if all fields have been
bound to explicit values. - Version 25.0:
- stdlib
* New function filelib:ensure_path/1 will ensure that all
directories for the given path exists
* New functions groups_from_list/2 and groups_from_list/3 in
the maps module
* New functions uniq/1 uniq/2 in the lists module
* New PRNG added to the rand module, for fast pseudo-random
numers.
- compiler, kernel, stdlib, syntax_tools:
* Added support for selectable features as described in EEP-60.
Features can be enabled/disabled during compilation with
options (ordinary and +term) to erlc as well as with
directives in the file. Similar options can be used to erl
for enabling/disabling features allowed at runtime. The new
maybe expression EEP-49 is fully supported as the feature
maybe_expr.
- erts & JIT:
* The JIT now works for 64-bit ARM processors.
* The JIT now does type-based optimizations based on type
information in the BEAM files.
* Improved the JIT’s support for external tools like perf and
gdb, allowing them to show line numbers and even the original
Erlang source code when that can be found.
- erts, stdlib, kernel:
* Users can now configure ETS tables with the
{write_concurrency, auto} option. This option forces tables
to automatically change the number of locks that are used at
run-time depending on how much concurrency is detected. The
{decentralized_counters, true} option is enabled by default
when {write_concurrency, auto} is active.
* Benchmark results comparing this option with the other ETS
optimization options are available here: benchmarks.
* To enable more optimizations, BEAM files compiled with OTP 21
and earlier cannot be loaded in OTP 25.
* The signal queue of a process with the process flag
message_queue_data=off_heap has been optimized to allow
parallel reception of signals from multiple processes. This
can improve performance when many processes are sending in
parallel to one process. See benchmark.
* The Erlang installation directory is now relocatable on the
file system given that the paths in the installation’s
RELEASES file are paths that are relative to the
installations root directory.
* A new option called short has been added to the functions
erlang:float_to_list/2 and erlang:float_to_binary/2. This
option creates the shortest correctly rounded string
representation of the given float that can be converted back
to the same float again.
* Introduction of quote/1 and unquote/1 functions in the
uri_string module - a replacement for the deprecated
functions http_uri:encode and http_uri:decode.
* The new module peer supersedes the slave module. The slave
module is now deprecated and will be removed in OTP 27.
* global will now by default prevent overlapping partitions due
to network issues. This is done by actively disconnecting
from nodes that reports that they have lost connections to
other nodes. This will cause fully connected partitions to
form instead of leaving the network in a state with
overlapping partitions.
* It is possible to turn off the new behavior by setting the
the kernel configuration parameter
prevent_overlapping_partitions to false. Doing this will
retain the same behavior as in OTP 24 and earlier.
* The format_status/2 callback for gen_server, gen_statem and
gen_event has been deprecated in favor of the new
format_status/1 callback.
* The new callback adds the possibility to limit and change
many more things than the just the state.
* The timer module has been modernized and made more efficient,
which makes the timer server less susceptible to being
overloaded. The timer:sleep/1 function now accepts an
arbitrarily large integer.
- compiler:
* The maybe ... end construction as proposed in EEP-49 has been
implemented. It can simplify complex code where otherwise
deeply nested cases would have to be used.
* To enable maybe, give the option {enable_feature,maybe_expr}
to the compiler. The exact option to use will change in a
coming release candidate and then it will also be possible to
use from inside the module being compiled.
* When a record matching or record update fails, a {badrecord,
ExpectedRecordTag} exception used to be raised. In this
release, the exception has been changed to {badrecord,
ActualValue}, where ActualValue is the value that was found
instead of the expected record.
* Add compile attribute -nifs() to empower compiler and loader
with information about which functions may be overridden as
NIFs by erlang:load_nif/2.
* Improved and more detailed error messages when binary
construction with the binary syntax fails. This applies both
for error messages in the shell and for
erl_error:format_exception/3,4.
* Change format of feature options and directives for better
consistency. Options to erlc and the -compile(..) directive
now has the format {feature, feature-name, enable | disable}.
The -feature(..) now has the format -feature(feature-name,
enable | disable).
- crypto:
* Add crypto:hash_equals/2 which is a constant time comparision
of hashvalues.
- ssl:
* Introducing a new (still experimental) option
{certs_keys,[cert_key_conf()]}. With this a list of a
certificates with their associated key may be used to
authenticate the client or the server. The certificate key
pair that is considered best and matches negotiated
parameters for the connection will be selected.
- public_key:
* Functions for retrieving OS provided CA-certs added.
- dialyzer:
* Optimize operations in the erl_types module. Parallelize the
Dialyzer pass remote.
* Added the missing_return and extra_return options to raise
warnings when specifications differ from inferred types.
These are similar to, but not quite as verbose as overspecs
and underspecs.
* Dialyzer now better understands the types for min/2, max/2,
and erlang:raise/3. Because of that, Dialyzer can potentially
generate new warnings. In particular, functions that use
erlang:raise/3 could now need a spec with a no_return()
return type to avoid an unwanted warning. - Fix build for Factory. Currently, any Java version
is fine for Erlang. - Changes for 24.3.2:
* erl_interface: Fix compile error regarding gethostbyaddr_r on
Android. Error introduced in OTP 24.3.
* kernel: Fix failed accepted connection setup after previous
established connection from same node closed down silently.
* kernel: Fixed a problem where typing Ctrl-R in the shell could
hang if there were some problem with the history log file.
- Changes for 24.3.1:
* dialyzer: There could be spurious warnings for unknown types
when a type was a subtype of an existing type that was a
subtype of an unknown type.
* ssl: Client certification could fail for TLS-1.3 servers that
did not include the certificat_authorties extension in its
certificate request message.
- Changes for 24.3:
* megaco: The compilation time is no longer recorded in BEAM
files. There remained several undocumented functions that
attempted to retrieve compilation times. Those have now been
removed.
* megaco: Update the performance and debug chapters of the megaco
user's guide. Also some updates to the meas tools.
* compiler: The expression <<0/native-float>>=Bin would always
fail to match, while <<0/float-native>>=Bin would match
(provided that Bin contained the binary representation of 0.0)
* compiler: The compiler will now compile huge functions with
straight-line code faster.
* erl_interface: Add --enable-ei-dynamic-lib configure option
that will make erl_interface also release a dynamic library
version of libei.
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation
on the external term format larger than 2 GB cannot be handled.
* sasl: Fix bug in systools:make_script/1 documentation.
* inets: The compilation time is no longer recorded in BEAM
files. There remained several undocumented functions that
attempted to retrieve compilation times. Those have now been
removed.
* inets: Documentation fix for inets:services_info/0, which now
describes that Info might be a Reason term() in case when
{error, Reason} is returned as service info.
* crypto: The crypto app in OTP can since OTP-24.2 be compiled,
linked and used with the new OpenSSL 3.0 cryptolib. The crypto
app has 3.0 support has been improved, but is still *not
recommended* for other usages than experiments and alpha
testing. There are not yet any guaranties that it works, not
even together with other OTP applications like for example SSL
and SSH, although there are no known errors. Since the previous
release, OTP-24.2, the following improvements have been done: -
It has been tested during nearly every nightly test on the OTP
lab - The hash algorithms md4 and ripemd160 have been enabled
with OpenSSL 3.0. - The ciphers blowfish_cbc, blowfish_ecb,
des_cbc, des_cfb, des_ecb, rc2_cbc and rc4 have been enabled
with OpenSSL 3.0. Disabled or unsupported with OpenSSL 3.0 are
still: - ENGINE support - FIPS mode - Other providers than the
built-in ones - Compiling and linking with OpenSSL 3.0
cryptolib in compatibility modes (for example to behave as
1.1.1) and, the ciphers blowfish_cfb64 and blowfish_ofb64 are
not supported and will not be either. Deprecated functions in
the OpenSSL 3.0 cryptolib must not be disabled as OTP/crypto
still uses some of the deprecated API functions. The gcc flag
- Wno-deprecated-declarations is set to prevent deprecation
warnings to be printed when compiling.
* crypto: Crypto is adapted to LibreSSL 3.5.0 on OpenBSD.
* crypto: New configure option ( --disable-otp-test-engine) to
prohibit the build of the OTP test engine used in some test
suites. The reason is that the test engine could be hard to
compile on for instance LibreSSL 3.5.0. For that particular
cryptolib version (or higher), this configure option is set
automatically.
* jinterface: Fix bug in OtpOutputStream.write_pid/4 and
write_ref/3 causing faulty encodig. Bug exists since OTP 23.0.
* wx: Removed the static_data option from wxImage creation
functions, as it was broken and could lead to crashes. Now
image data is always copied to wxWidgets as was the default
behavior. Removed some non working wxGridEvent event types,
which have there own events in newer wxWidgets versions, and
added a couple of event types that where missing in wx.
* asn1: Add support for the maps option in combination with the
jer backend.
* snmp: The compilation time is no longer recorded in BEAM files.
There remained several undocumented functions that attempted to
retrieve compilation times. Those have now been removed.
* snmp: [agent] Remove expectation of socket being a port.
* common_test: OTP internal test fix.
* runtime_tools: Fixed bug in scheduler:utilization(Seconds) that
would leave the scheduler_wall_time system flag incorrectly
enabled.
* runtime_tools: Add scheduler:get_sample/0 and get_sample_all/0.
Also clarify scheduler module documentation about how it
depends on system flag scheduler_wall_time.
* erts: Fixed a bug in the x86 JIT that might cause floating
point instructions to wrongly throw an exception.
* erts: Preserve correct nodedown_reason if supervised
distribution controller processes exit with {shutdown, Reason}.
* erts: Handling of send_timeout for gen_tcp has been corrected
so that the timeout is honored also when sending 0 bytes.
* erts: By default global does not take any actions to restore a
fully connected network when connections are lost due to
network issues. This is problematic for all applications
expecting a fully connected network to be provided, such as for
example mnesia, but also for global itself. A network of
overlapping partitions might cause the internal state of global
to become inconsistent. Such an inconsistency can remain even
after such partitions have been brought together to form a
fully connected network again. The effect on other applications
that expects that a fully connected network is maintained may
vary, but they might misbehave in very subtle hard to detect
ways during such a partitioning. In order to prevent such
issues, we have introduced a prevent overlapping partitions fix
which can be enabled using the prevent_overlapping_partitions
kernel(6) parameter. When this fix has been enabled, global
will actively disconnect from nodes that reports that they have
lost connections to other nodes. This will cause fully
connected partitions to form instead of leaving the network in
a state with overlapping partitions. Note that this fix has to
be enabled on all nodes in the network in order to work
properly. Since this quite substantially changes the behavior,
this fix is currently disabled by default. Since you might get
hard to detect issues without this fix you are, however,
strongly advised to enable this fix in order to avoid issues
such as the ones described above. As of OTP 25 this fix will
become enabled by default.
* erts: Corrected the type specification of erlang:seq_trace/2.
* erts: Fix memory leak when tracing on running on a process that
only handle system tasks or non-message signals (for example
process_info requests).
* erts: Add support for using socket:sockaddr_in() and
socket:sockaddr_in6() when using gen_sctp, gen_tcp and gen_udp.
This will make it possible to use Link Local IPv6 addresses.
* erts: Show on_load failure reasons in embedded mode.
* erts: Compile date saved in the Erlang VM executable has been
removed.
* erts: Improve documentation for the dynamic node name feature.
* ssh: Fix makefile dependency bugs.
* ssh: Fixed faulty OpenSSH decoding of Ed25519/Ed448 keys in the
OpenSSH format openssh_key_v1.
* ssh: Correction of ssh_file typing, specially for the
experimental openssh-key-v1 encoding.
* ssh: Improper tag for private ED keys when encoding with
ssh:encode/2. The tuple had ed_priv as first element, but
should have had ed_pri. This is now corrected. *** POTENTIAL
INCOMPATIBILITY ***
* ssh: Add support for Ed25519/Ed448 SSH host keys in the RFC
4716 format ("-----BEGIN EC PRIVATE KEY-----") generated by for
example openssl or via Erlang functions (i.e.
public_key:generate_key({namedCurve, ed25519})). Ed25519 SSH
host keys generated by ssh-keygen was, and are still,
supported.
* kernel: Handling of send_timeout for gen_tcp has been corrected
so that the timeout is honored also when sending 0 bytes.
* kernel: By default global does not take any actions to restore
a fully connected network when connections are lost due to
network issues. This is problematic for all applications
expecting a fully connected network to be provided, such as for
example mnesia, but also for global itself. A network of
overlapping partitions might cause the internal state of global
to become inconsistent. Such an inconsistency can remain even
after such partitions have been brought together to form a
fully connected network again. The effect on other applications
that expects that a fully connected network is maintained may
vary, but they might misbehave in very subtle hard to detect
ways during such a partitioning. In order to prevent such
issues, we have introduced a prevent overlapping partitions fix
which can be enabled using the prevent_overlapping_partitions
kernel(6) parameter. When this fix has been enabled, global
will actively disconnect from nodes that reports that they have
lost connections to other nodes. This will cause fully
connected partitions to form instead of leaving the network in
a state with overlapping partitions. Note that this fix has to
be enabled on all nodes in the network in order to work
properly. Since this quite substantially changes the behavior,
this fix is currently disabled by default. Since you might get
hard to detect issues without this fix you are, however,
strongly advised to enable this fix in order to avoid issues
such as the ones described above. As of OTP 25 this fix will
become enabled by default.
* kernel: Fix bug where logger would crash when logging a report
including improper lists.
* kernel: Make erlang:set_cookie work for dynamic node names.
* kernel: Add support for using socket:sockaddr_in() and
socket:sockaddr_in6() when using gen_sctp, gen_tcp and gen_udp.
This will make it possible to use Link Local IPv6 addresses.
* kernel: A net_tickintensity kernel parameter has been
introduced. It can be used to control the amount of ticks
during a net_ticktime period. A new net_kernel:start/2 function
has also been introduced in order to make it easier to add new
options. The use of net_kernel:start/1 has been deprecated.
* kernel: Improve documentation for the dynamic node name
feature.
* erl_docgen: Fix css for large tables and images on small
screens
* erl_docgen: Fix bug with codeinclude tag that caused it to not
include the code if used in a correct, but unexpected way.
* observer: Calculate the display width in etop, instead of hard-
coding it to 89 characters.
* debugger: Fix record index matching, it was broken and could
never match.
* ssl: Improved error handling.
* ssl: Before this change, net_kernel used with TLS distribution
might be leaking processes in case of connectivity issues.
* ssl: Fix makefile dependency bugs.
* ssl: Make sure the TLS sender process handles explicit calls to
erlang:disconnect_node properly, avoiding potential hanging
problems in net_kernel.
* ssl: Add support for TLS-1.3 certificate_authorities extension.
And process certificate_authorities field in pre-TLS-1.3
certificate requests.
* ssl: Support password fun for protected keyfiles in ssl:connect
function.
* ssl: Add in some cases earlier detection of possible DoS
attacks by malicious clients sending unexpected TLS messages
instead of the client hello. Note that such attacks are already
mitigated by providing a timeout for the TLS handshake.
* eldap: Fix eldap extensibleMatch dnAttributes option. According
to the ldap ASN1 the dnAttributes should be a bool, instead it
was generated as a string.
* eldap: Implemented paged searches according to https://www.rfc-
editor.org/rfc/rfc2696.txt
* public_key: Support password fun for protected keyfiles in
ssl:connect function.
* stdlib: The compilation time is no longer recorded in BEAM
files. There remained several undocumented functions that
attempted to retrieve compilation times. Those have now been
removed.
* mnesia: Reduce the number of locks taken during table copying,
should reduce the startup time on large systems.
* diameter: The compilation time is no longer recorded in BEAM
files. There remained several undocumented functions that
attempted to retrieve compilation times. Those have now been
removed. - Changes for 24.2.2:
* inets: Avoid intermediate ungraceful shutdown of the HTTP
server.
* ssh: The ssh sever parallel_login option was missing in OTP-24 - Changes for 24.2.1:
* ssl: Improve SNI (server name indication) handling so that
protocol version can be selected with regards to SNI. Also,
make sure that ssl:connection_information/1 returns the correct
SNI value.
* ssl: Fixed cipher suite listing functions so that the listing
of all cipher suites will be complete. Another fix for cipher
suite handling in OTP-24.1 accidentally excludes a few cipher
suites from the listing of all cipher suites.
* ssl: Reenable legacy cipher suite TLS_RSA_WITH_3DES_EDE_CBC_SHA
for explicit configuration in TLS-1.2, not supported by
default.
* ssl: Avoid unnecessary logs by better adjusting the tls_sender
process to the new supervisor structure in OTP-24.2
* erts: Fixed a memory leak in file:read_file_info/2 and
file:read_file/1 on Windows.
* erts: Fix GC emulator crash when spawn_request was used when
message tracing was enabled. - Changes for 24.2:
* compiler: When the compiler is invoked by Dialyzer, it will no
longer apply an optimization of binary patterns that would turn
the pattern <<"bar">> into <<6447474:24>>, which would be very
confusing when printed out by Dialyzer.
* compiler: The compiler would replace known failing calls (such
as atom_to_list(42)) with a call to error(badarg). With the
extended error information introduced in OTP 24 (EEP 54), those
"optimized" calls would not have extended error information. To
ensure that as much extended error information as possible is
available, the compiler now keeps the original call even when
it is known to fail.
* sasl: Make release_handler even more resilient against exiting
processes during upgrade. Same kind of bug fix as OTP-16744
released in sasl-4.0.1 (OTP 23.1).
* ssl: Allow re-connect on DTLS sockets Can happen when a
computer reboots and connects from the same client port without
the server noticing should be allowed according to RFC.
* ssl: Fix tls and non-tls distribution to use
erl_epmd:address_please to figure out if IPv4 or IPv6 addresses
should be used when connecting to the remote node. Before this
fix, a dns lookup of the remote node hostname determined which
IP version was to be used which meant that the hostname had to
resolve to a valid ip address.
* ssl: Use supervisor significant child to manage tls connection
process and tls sender process dependency.
* ssl: Random generation adjustment for TLS1.3
* ssl: Allow any {03,XX} TLS record version in the client hello
for maximum interoperability
* mnesia: Documentation and minor code cleanup.
* common_test: Before this change, group handling grammar was
ambiguous and also group paths did not support test specs.
* common_test: Before this change, it was not possible to link to
a particular header entry in Common Test log. Change adds right
aligned anchor icons in HTML test logs.
* parsetools: The default parser include file for yecc (yeccpre)
will no longer crash when attempting to print tokens when
reporting an error.
* tools: Erlang-mode fixed for newer versions of xref using CL-
Lib structures instead of EIEIO classes.
* inets: Correct HTTP server URI handling to fully rely on
uri_string. The server could mistreat some URI paths that in
turn could result in incorrect responses being generated.
* inets: Extend header values to httpc:request/5 to allow
binary() as well. Make error detection of invalid arguments to
httpc:request/5 be more precise so an error is returned in more
cases instead of causing a hang or function_clause. Be more
precise in documentation regarding the types of arguments being
accepted.
* crypto: Fixed the C-warning "implicit declaration of function
'OpenSSL_version_num'" if compiling with an early LibreSSL
version.
* crypto: FIPS availability was not checked correctly for AEAD
ciphers.
* crypto: Fixed that cipher aliases (like aes_cbc etc) could be
present even if the aliased cipher(s) (like aes_128_cbc,
aes_256_cbc,... etc) was missing.
* crypto: The crypto app in OTP can now be compiled, linked and
used with the new OpenSSL 3.0 cryptolib. It has not yet been
extensively tested and is in this release *not recommended* for
other usages than experiments and alpha testing. There are not
yet any guaranties that it works, not even together with other
OTP applications like for example SSL and SSH, although there
are no known errors. Compiling and linking with OpenSSL 3.0
cryptolib in compatibility modes (for example to behave as
1.1.1) are not tested. It is not tested with external
providers. The support for FIPS mode does not yet work, and is
disabled when compiled with OpenSSL 3.0. Deprecated functions
in the OpenSSL 3.0 cryptolib must not be disabled as OTP/crypto
still uses some of the deprecated API functions. The gcc flag
- Wno-deprecated-declarations is set to prevent deprecation
warnings to be printed when compiling. The hash algorithms md4
and ripemd160 are disabled temporarily when compiled with
OpenSSL 3.0. The ciphers blowfish_cbc, blowfish_cfb64,
blowfish_ecb, blowfish_ofb64, des_cbc, des_cfb, des_ecb,
rc2_cbc and rc4 are disabled temporarily when compiled with
OpenSSL 3.0.
* crypto: The error handling in crypto is partly refactored using
the new error reporting support. Errors earlier propagated like
exceptions are still so, but when the failing function is
called from the terminal - for example during failure hunting -
a more descriptive text is produced.
* crypto: A new function crypto:info/0 which presents some data
about the compilation and linkage of the crypto nif is added.
* crypto: Added the pbkdf2_hmac/5 function to the crypto module.
It calls the PKCS5_PBKDF2_HMAC function which implements PBKD2
with HMAC in an efficient way.
* stdlib: Fix rendering of nbsp on terminals that do not support
unicode.
* stdlib: Improved the erl_error printout for when re fails to
compile a regular expression to also print hints about why the
compilation failed.
* stdlib: Fixed spec for supervisor_bridge:start_link().
* stdlib: Added missing shutdown clauses in supervisor which
could cause erroneous error reports.
* stdlib: Add the no_auto_import_types to erl_lint to allow a
module to define types of the same name as a predefined type.
* erts: When matching and constructing utf16 segments in the
binary syntax, the native flag would be ignored. That is, the
endian would always be big endian even on a little-endian
computer (almost all modern computers).
* erts: Fix the help printout of +JPperf.
* erts: Fix bug that could cause Erlang to deadlock during
creation of an Erlang crash dump.
* erts: Fixed C++ build errors on some aarch64 platforms.
* erts: For macOS, the Info.plist file embedded in the runtime
system now only contains the absolute minimum amount of
information needed for the web view in wx to work towards
localhost. The other fields have been removed, allowing an
application packaged in a bundle to specify the application
name and other parameter in its own Info.plist file.
* erts: Fix bug in internal stacks (WSTACK and ESTACK) used by
term_to_binary/2 to encode terms. The bug could cause a
segfault if a very very large map was to be encoded with the
deterministic option given.
* erts: Improve the error printout when open_port/2 fails because
of invalid arguments.
* erts: Fix bug in crash dumps where the stackframe of a process
would be printed using an incorrect format. Crash dump viewer
has also been fixed to be able read the broken stack format.
The bug has existed since Erlang/OTP 23.0.
* erts: An option for enabling dirty scheduler specific allocator
instances has been introduced. By default such allocator
instances are disabled. For more information see the
documentation of the +Mdai erl command line argument.
* erts: Minor optimization of receive markers in message queues.
* erts: All predefined types have been added to the erlang module
together with documentation. Any reference to a predefined type
now links to that documentation so that the user can view it.
* erts: Suppress a code checker warning caused by debug builds of
YCF. YCF tries to get a conservative estimate of the bottom of
the stack by reading and returning a call stack allocated
variable.
* erts: Add file and product properties to erl.exe and werl.exe.
* erts: Micro optimization in bitstring append operations.
* erts: Responsiveness of processes executing on normal or low
priority could suffer due to code purging or literal area
removal on systems with a huge amount of processes. This since
during these operations all processes on the system were
scheduled for execution at once. This problem has been fixed by
introducing a limit on outstanding purge and copy literal
requests in the system. By default this limit is set to twice
the amount of schedulers on the system. This will ensure that
schedulers will have enough work scheduled to perform these
operations as quickly as possible at the same time as other
work will be interleaved to a much higher degree. Performance
of these operations will however be somewhat degraded due to
the overhead of enforcing this limit compared to when using a
very large limit. This limit can be set by passing the +zosrl
command line argument to erl, or by calling
erlang:system_flag(outstanding_system_requests_limit,
NewLimit).
* kernel: socket:which_sockets( pid() ) uses wrong keyword when
looking up socket owner ('ctrl' instead of 'owner').
* kernel: In epmd_ntop, the #if defined(EPMD6) conditional was
inverted and it was only including the IPv6-specific code when
EPMD6 was undefined. This was causing IPv6 addrs to be
interpreted as IPv4 addrs and generating nonsense IPv4
addresses as output. Several places were incorrectly using
'num_sockets' instead of 'i' to index into the iserv_addr array
during error logging. This would result in a read into
uninitialized data in the iserv_addr array. Thanks to John
Eckersberg for providing this fix.
* kernel: Minor fix of the erl_uds_dist distribution module
example.
* kernel: A bug has been fixed for the legacy TCP socket adaption
module gen_tcp_socket where it did bind to a socket address
when given a file descriptor, but should not.
* kernel: Improve the error printout when open_port/2 fails
because of invalid arguments.
* kernel: Calling socket:monitor/1 on an already closed socket
should succeed and result in an immediate DOWN message. This
has now been fixed.
* kernel: Fix the configuration option logger_metadata to work.
* kernel: Fix tls and non-tls distribution to use
erl_epmd:address_please to figure out if IPv4 or IPv6 addresses
should be used when connecting to the remote node. Before this
fix, a dns lookup of the remote node hostname determined which
IP version was to be used which meant that the hostname had to
resolve to a valid ip address.
* kernel: Add logger:reconfigure/0.
* kernel: Add socket function ioctl/2,3,4 for socket device
control.
* kernel: Add simple support for socknames/1 for gen_tcp_socket
and gen_udp_socket.
* kernel: The types for callback result types in gen_statem has
bee augmented with arity 2 types where it is possible for a
callback module to specify the type of the callback data, so
the callback module can get type validation of it.
* erl_docgen: Fix codeinclude tag to correctly respect the type
attribute.
* erl_docgen: The HTML documentation has been updated to collapse
better on small screens.
* erl_docgen: All predefined types have been added to the erlang
module together with documentation. Any reference to a
predefined type now links to that documentation so that the
user can view it.
* snmp: Handling of test config flag when starting "empty".
* snmp: Add support for new authentication algorithms (SHA-224,
SHA-256, SHA-384 and SHA-512), according to RFC 7860.
* snmp: Improve debug info for (snmp) manager.
* wx: Fix crash in cleanup code when a gui application is
exiting. Fix errors in the OpenGL wrapper that could cause
crashes and improve the documentation.
* edoc: Add option link_predefined_types that is used to create
links to erlang predefined types. This is mainly to be used by
erl_docgen when creating the Erlang/OTP documentation.
* dialyzer: Fixed a crash when opaque types contained certain
unicode characters.
* dialyzer: When the compiler is invoked by Dialyzer, it will no
longer apply an optimization of binary patterns that would turn
the pattern <<"bar">> into <<6447474:24>>, which would be very
confusing when printed out by Dialyzer.
* observer: Fix bug in crash dumps where the stackframe of a
process would be printed using an incorrect format. Crash dump
viewer has also been fixed to be able read the broken stack
format. The bug has existed since Erlang/OTP 23.0.
* ssh: The value of the connect_timeout option is now used as
default value for the negotiation timeout.
* ssh: Add better error handling in connect/2,3,4. Detect
incorrect arguments and return an informative error tuple
instead of throwing a function_clause or similar.
* ssh: Make ssh algorithm selection better handle dynamic changes
changes in crypto fips mode.
* megaco: [megaco_tcp] When connect fails, include more info in
the error reason.
- Changes for 24.1.7:
* ssh: Fixed a race condition in the acceptor loop: if a client
disconnected immediately after the tcp connect, the server
could cease handling connection on that address:port.
- Changes for 24.1.6:
* ssl: Correct typo of ECC curve name in signature algorithm
handling. Will make the signature algorithm
ecdsa_secp521r1_sha512 succeed.
* ssl: Suppress authenticity warning when option verify_none is
explicitly supplied.
- Changes for 24.1.5:
* erts: The runtime system could call select() with a too large
timeout value when executing on MacOS. This could in turn cause
the runtime system to crash.
* erts: The fix for Linux's behaviour when reconnecting an UDP
socket in PR-5120 released in OTP-24.1.2 has been refined to
only dissolve the socket's connection before a connect if the
socket is already connected, that is: only for a reconnect.
This allows code to open a socket with an ephemeral port, get
the port number and connect; without the port number changing
(on Linux). This turned out to have at least one valid use case
(besides test cases). Should one reconnect the socket then the
port number may change, on Linux; it is a known quirk, which
can be worked around by binding to a specific port number when
opening the socket. If you can do without an ephemeral port,
that is...
* erts: Certain distributed signals that for various reasons must
to be forced into the distribution buffer even when it is full
would instead be lost if the distribution buffer was full when
sent. The effected signals:
* kernel: The internal, undocumented, but used, module inet_dns
has been fixed to handle mDNS high bit usage of the Class
field. Code that uses the previously obsolete, undocumented and
unused record field #dns_rr.func will need to be updated since
that field is now used as a boolean flag for the mDNS high
Class bit. Code that uses the also undocumented record
[#]dns_query will need to be recompiled since a boolean field
[#]dns_query.unicast_response has been added for the mDNS high
Class bit. *** POTENTIAL INCOMPATIBILITY ***

- Changes for 24.1.4:
* erts: Fix bug where a gen_tcp write error that happened during
a delayed_send would cause a use after free segfault.
* erts: Fix x86 JIT bug where a rem instruction could cause a
segfault if given values that would cause an badarith
exception.
- Changes for 24.1.3:
* ssl: Fix TLS-1.2 RSA-PSS negotiation and also fix broken
certificate request message for pre-TLS-1.3 servers.
* ssl: Fix CRL issuer verification that under some circumstances
could fail with a function_clause error.
* erts: Reduction counter was not updated before and after doing
apply operations on the runtime system with the jit enabled.
This caused reduction counting to get out of sync if a garbage
collection was made as part of the apply operation.
* erts: This fixes a bug in erts_factory_undo that caused the
heap to not be reset correctly. The erts_factory_undo function
is, for example, called when a binary_to_term/1 call fails to
reset the heap to its state before the binary_to_term/1 call.
This can cause the heap to contain invalid terms which
potentially can cause issues (e.g., crashes) when the whole
heap is scanned.
* erts: When attempting to construct a binary with an segment
having an illegal type for the size (e.g. an atom), there could
be an unnecessary memory allocation (and subsequent
deallocation) before the operation failed. Amended to fail
before allocating any memory for the binary.
* erts: Fix bug in persistent_term when a key-value pair contains
a magic reference that is referred more than once. Magic
references are NIF resources or returned from BIFs like
ets:new, atomics:new. The bug could cause the memory of the
referred resource to be prematurely deallocated. The bug also
apply to magic references in message passing on a runtime built
with configure option --enable-sharing-preserving. Bug exist
for 64-bit since OTP-24.0 and for 32-bit since OTP-20.0.
* erts: Fixed a crash when inspecting the stack trace of an
exception raised at a very high line number. This bug was
introduced in OTP 24.
* erts: The following two bugs that caused erlang:demonitor() to
behave erroneously have been fixed. The bugs were only
triggered if the monitor that was removed by demonitor() had
previously been created simultaneously as a monitor and as an
alias. - Changes for 24.1.2:
* kernel: The undocumented DNS encode/decode module inet_dns has
been cleaned up to handle the difference between "symbolic" and
"raw" records in a more consistent manner. PR-5145/OTP-17584
introduced a change that contributed to an already existing
confusion, which this correction should remedy.
* erts: The python scripts that existed in
erts/lib_src/yielding_c_fun/lib/tiny_regex_c/scripts had a
license that was incompatible with Erlang/OTP's license. This
ticket removes these scripts that were not used by us.
* ssl: Before that change, TLS downgrade could occasionally fail
when data intended for downgraded socket were delivered
together with CLOSE_NOTIFY alert to ssl app.
* ssl: Avoid re-encoding of decoded certificates. This could
cause unexpected failures as some subtle encoding errors can be
tolerated when decoding but hence creating another sequence of
bytes if the decoded value is re-encoded.
* ssl: Fix possible process leak when the process doing
ssl:transport_accept dies before initiating the TLS handshake.
* ssl: Fix dtls memory leak, the replay window code was broken.
* public_key: Avoid re-encoding of decoded certificates. This
could cause unexpected failures as some subtle encoding errors
can be tolerated when decoding but hence creating another
sequence of bytes if the decoded value is re-encoded.
* crypto: Fixed minor memory leak at crypto module purge.
* crypto: Fix possible inconsistency in fips mode when linking
with some cryptolibs.
- Changes for 24.1.1:
* kernel: Add more info about the socket 'type' ('socket' or
'port') for the DOWN message when monitoring sockets.
* stdlib: Fixed a bug that could cause a child to become orphaned
when a supervisor died between unlinking and sending the
shutdown signal to this child. There was also a possibility for
erratic supervisor reports caused by a race between a
supervisor shutting down a child and that child exiting by
itself at the same time.
* erts: A race between an exiting port and handling of
simultaneously received signals to that port could cause a
runtime system crash. The effected signals are link, monitor
and demonitor. On OTP 22 a similiar race could also cause a
memory leak when receiving an unlink signal.
* erts: A user defined tag on a monitor message could cause the
runtime system to crash when the monitor message had been
received.
* erts: A call to erlang:demonitor(Ref) where the reference Ref
referred to an active alias, but not an active monitor, caused
the runtime system to crash.
* erts: The message queue of a process entered an inconsistent
state after a receive expression with an invalid timeout value
was executed. If the exception raised due to the invalid
timeout value was caught, the following receive expression
executed by the process could fail to match messages already
present in the message queue. On OTP 24 this could also cause
the whole runtime system to crash.
* erts: Sending a Port ! {PortOwner, close} signal from a process
other than the port owner could erroneously trigger a badsig
exit signal being sent to the port owner process even though
the correct PortOwner had been passed in the signal.
* snmp: Sockets are monitored, but the handling of the 'DOWN'
message expected a new style socket ('socket'), old style
(port) was not handled.
- Changes for 24.1:
* kernel: The extended error information has been corrected and
improved for the following BIFs: binary_to_existing_atom/2,
list_to_existing_atom/1, erlang:send_after/{3,4}, and
erlang:start_timer/{3,4}.
* kernel: Fixed rare bug that could cause net_kernel process to
hang for ever. Have seen to happen with massive number of TLS
connections while remote nodes are restarting. Bug exists since
OTP-22.0.
* kernel: Improve handling of closed sockets for inet:info/1.
* kernel: This change fixes a performance problem introduced in
pull-request #2675. Pull-request #2675 made so the system tried
to start children of already started applications which is
unnecessary. This change fixes this performance problem.
* kernel: Fix code:get_doc/1 to not crash when module is located
in an escript.
* kernel: Parsing of the result value in the native DNS resolver
has been made more defensive against incorrect results.
* kernel: A bug in the option handling for the legacy socket
adaptor, that is; when using inet_backend = socket, has been
fixed. Now socket options are set before the bind() call so
options regarding, for example address reuse have the desired
effect.
* kernel: inet:ntoa/1 has been fixed to not accept invalid
numerical addresses.
* kernel: Parsing of DNS records has been improved for records of
known types to not accept and present malformed ones in raw
format.
* kernel: The ip_mreq() type for the {ip,add_membership} and
{ip,drop_membership} socket options has been corrected to have
an interface field instead of, incorrectly, an address field.
* kernel: Add simple utility function to display existing sockets
i the erlang shell (socket:i/0).
* kernel: gen_udp can now be configured to use the socket inet-
backend (in the same way as gen_tcp).
* kernel: Functions erlang:set_cookie(Cookie) and
erlang:get_cookie(Node) have been added for completeness and to
facilitate configuring distributed nodes with different
cookies. The documentation regarding distribution cookies has
been improved to be less vague.
* kernel: A workaround has been implemented for Linux's quirky
behaviour to not adjust the source IP address when connecting a
connected (reconnecing) UDP socket. The workaround is to, on
Linux, always dissolve any connection before connecting an UDP
socket.
* kernel: Documented our recommendation against opening NFS-
mounted files, FIFOs, devices, and similar using file:open/2.
* debugger: Improve record handling, print known records with
record syntax.
* observer: Atoms with Unicode code points greater than 255 (for
example Greek or Cyrillic characters) would not be displayed
correctly by crashdump_viewer.
* observer: Fix the crashdump_viewer to be able to parse
monitor_node/2 monitors correctly.
* observer: Observer now has a sectiion for new socket.
* observer: Added a trace all button to the trace window.
* parsetools: Fix a bug in Leex which caused the Erlang Compiler
to generate warnings.
* parsetools: Fix a bug in Yecc which caused the Erlang Compiler
to generate warnings.
* mnesia: Fixed that index keys was deleted for set tables when
mnesia:delete_object/1 tried to delete a non-existing record.
* mnesia: Optimized table loading and added max_transfer_size
configuration parameter.
* stdlib: Fix io:format with ~p to no longer interpret floats as
printable characters.
* stdlib: Fix specs for base64 encode/decode functions to also
include 0.
* stdlib: The failing call io:format("~p\n") would result in a
warning for line number 0 instead of the correct line and
column numbers. This has been corrected, and all warnings for
failing calls to io:format() has been rephrased to make it
clearer exactly what the problem is.
* stdlib: When the options warn_missing_spec and export_all were
given, there would only be warnings for missing specs for
functions that had been explicitly exported using an -export
attribute.
* stdlib: Calling c:ls/1 with an atom whose contents is the the
name of a file (as opposed to a directory) would crash.
* stdlib: The MODULE and MODULE_STRING macros would always appear
to be defined (when tested by -ifdef), even though no -module()
declaration had been seen yet. Changed so that -ifdef ?MODULE.
will not consider ?MODULE defined if -module() has not been
previously seen.
* stdlib: Fix bug with rendering of missing types and callbacks
in shell_docs.
* stdlib: When the deterministic option was given to the
compiler, the ?FILE macro would be expanded to full path of the
source file before the first include directive and to base part
of the filename after include directive.
* stdlib: Fixed broken win32reg:delete_key and fixed
win32reg:value for default value.
* stdlib: Fixed error information for the call maps:get(some_key,
[#]{}).
* stdlib: Most output functions in the io module now print extra
error information when provided with invalid arguments. The
functions are: io:format, io:fwrite, io:put_chars, io:nl and
io:write.
* stdlib: EEP-54 (Provide more information about errors) now
includes two new return values for the format_error callback,
general and reason. Multi-line error descriptions returned from
a format_error callback are now correctly indented. The
documentation for erl_error, error/3 and Errors and Error
Handling in the Erlang Reference Manual have been extended.
* stdlib: In the documentation for the lists module, it has been
clarified that predicate funs must return a boolean.
* stdlib: The documentation for c:c/1, c:c/2, and c:c/3 has been
clarified.
* tools: The cover tool would not work on modules compiled with
the tuple_calls option.
* common_test: Float allowed as multiply_timetraps parameter.
* common_test: Remove usage of legacy API macro and functions.
* erts: Atoms with Unicode code points greater than 255 (for
example Greek or Cyrillic characters) would not be displayed
correctly by crashdump_viewer.
* erts: Fix rare minor memory leak related to jit code loading.
* erts: The extended error information has been corrected and
improved for the following BIFs: binary_to_existing_atom/2,
list_to_existing_atom/1, erlang:send_after/{3,4}, and
erlang:start_timer/{3,4}.
* erts: Fix bug provoked when building with gcc 10 and link time
optimization (-flto), causing Erlang compiler to crash. Bug
exists since OTP-24.0.
* erts: Corrected bugs where builds were not reducible even when
the deterministic option was given. In particular, modules with
map literals with more than 32 elements could cause this
problem. As part of this fix, the term_to_binary BIF now
accepts the option deterministic.
* erts: After an exception has been caught in a process, the
stack trace would be kept in the process longer than necessary.
* erts: Fix rare race bug in memory management of distribution
entries. Have been seen to cause VM crash when massive number
of repeated concurrent failing connection attempts.
* erts: The configure test for --disable-esock-socket-registry
has been corrected so disabling now works.
* erts: init:stop() no longer unloads loaded code before
terminating the runtime system. On systems with slow CPUs (such
as Raspberry PI Zero), that can significantly speed up
termination of the runtime system.
* erts: Fixed match specifications that use maps in either the
guard or the body to work properly. With this fix both keys and
values in maps can be expressions. Various other crashes and
bugs when using maps in match specifications have also been
fixed.
* erts: Parsing of the result value in the native DNS resolver
has been made more defensive against incorrect results.
* erts: When binary_to_term/2 failed, the extended error
information would always blame the second argument even if the
actual error was in the first argument.
* erts: On 32-bit computers, binary_to_term/1,2 is now more
resilient against corrupted binaries containing maps in the
external format.
* erts: A call to process_info(Pid, status) could erroneously
report the status running when it should have reported waiting.
This occurred when the calling process was executing on a
higher priority than the process being inspected. This bug has
been present since OTP 21.0 (erts version 10.0).
* erts: Optimize memory usage of erts internal processes used
during code loading/purging by hibernating them after a long
time of inactivity.
* erts: Add the type erlang:stacktrace/0.
* erts: The arity argument of error/2,3 can now be none to
indicate that the calling functions arity should be used.
* erts: Optimize match spec compiler for immediate (single word)
constant terms.
* erts: Functions erlang:set_cookie(Cookie) and
erlang:get_cookie(Node) have been added for completeness and to
facilitate configuring distributed nodes with different
cookies. The documentation regarding distribution cookies has
been improved to be less vague.
* erts: A workaround has been implemented for Linux's quirky
behaviour to not adjust the source IP address when connecting a
connected (reconnecing) UDP socket. The workaround is to, on
Linux, always dissolve any connection before connecting an UDP
socket.
* erts: The internal documentation for how to use Yielding C Fun
(YCF) has been updated to contain text about best practices for
using YCF for ERTS.
* erts: Optimize garbage collection for processes with large
number of binaries, funs and/or external pids/ports/refs.
* erl_docgen: Fix codeinclude tags to work as part of reference
manual documentation.
* erl_docgen: Fix creation of link elements with anchors in
EEP-48 style documentation.
* dialyzer: Do not crash if a PLT file no longer exists.
* dialyzer: Fix bug in erl_types related to maps.
* dialyzer: Fix bugs in erl_types regarding improper lists.
* dialyzer: The underspecs and overspecs options will now
generate correct warnings for misused opaque types.
* eunit: In an eunit test, when a test case times out, include a
stacktrace.
* snmp: It is now possible to configure the built-in net-if
processes (both agent and manager) to use the new (gen_udp-)
option 'inet_backend'.
* asn1: A parameterized type with a SEQUENCE with extension
("...") made the compiler backend to crash. The previous fix
for this in GH-4514 was not complete.
* wx: Fix crash when closing an application.
* wx: Some functions with overloaded color arguments could not be
used. For example the copy constructor wxTextAttr:new(TextAttr)
did not work.
* wx: Added the Microsoft Edge WebView loader dll to the
installer on windows.
* wx: Handle specific Mac gui application events.
* erl_interface: erl_call now prints an error when the arguments
cannot be parsed.
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation
on the external term format larger than 2 GB cannot be handled.
* edoc: Fix broken documentation link in edoc_extract:file/4.
* ssl: Fix Makefile dependency generation to work no matter what
the ERL_TOP folder is called.
* ssl: If trying to downgrade a TLS-1.3 connection to a plain TCP
connection, possible TLS-1.3 session ticket messages will be
ignored in the "downgrade" state while waiting for the close
notify alert.
* ssl: Corrected error handling to correctly generate an
insufficient security alert when there are no suitable groups
that can be negotiated in TLS-1.3 instead of crashing resulting
in an internal error alert.
* ssl: Properly handle default session data storage. When a
client tries to reuse an expired session the default server
storage handling would crash loosing other session data. This
would cause a error report and possible loss of abbreviated
handshakes.
* ssl: Add support for RSA-PSS-PSS signatures and
signature_algorithms_cert in TLS-1.2. This is a TLS-1.3 RFC
requirement to backport this functionality.
* ssl: Use inet:monitor/1 to monitor listen-sockets so that we
are compatible with the new socket backend for gen_tcp.
* ssl: Enhance ssl:prf/4 handling and testing
* ssl: Enhanced cipher suite filtering functionality, making sure
TLS-1.3 and TLS-1.2 cipher suites can be supported correctly
together even when TLS-1.2 anonymous ciphers are included.
* ssl: Enhance gracefulness especially in TLS-1.3
* os_mon: On a Mac with Apple Silicon, memsup:get_os_wordsize/0
would return 32 instead of 64.
* ssh: Fixed that a slow start (>30s) of a client subsystem could
cause a log entry with the password.
* ssh: Fixed an error when running as an sftp server and a client
requests a directory contents listing. The fix is to handle the
error code {error, eacces} as {error, enoent} in the
ssh_sftpd:get_attrs/5 internal function; that is, just skip it.
* ssh: The "Key exchange failed" Info Report is now more
informative.
* inets: Before this change hrefs in dir listing page contained
percentage encoded forward slashes which did not work properly
with httpd.
* inets: Restored HTTP headers handling in inets/mod_esi.
* inets: inets/httpd dir listing icons and other improvements
* inets: httpc: Improve performance by removing redundant URI
handling
* compiler: If a parse transform raised an exception using
throw/1 or exit/1, the compiler would report that as an
internal compiler error, which would be confusing. Amended to
report that the parse transform failed.
* compiler: The failing call io:format("~p\n") would result in a
warning for line number 0 instead of the correct line and
column numbers. This has been corrected, and all warnings for
failing calls to io:format() has been rephrased to make it
clearer exactly what the problem is.
* compiler: When the options warn_missing_spec and export_all
were given, there would only be warnings for missing specs for
functions that had been explicitly exported using an -export
attribute.
* compiler: In rare circumstances, the compiler could emit an
incorrect warning for a term that was constructed but never
used.
* compiler: Corrected bugs where builds were not reducible even
when the deterministic option was given. In particular, modules
with map literals with more than 32 elements could cause this
problem. As part of this fix, the term_to_binary BIF now
accepts the option deterministic.
* compiler: The MODULE and MODULE_STRING macros would always
appear to be defined (when tested by -ifdef), even though no
- module() declaration had been seen yet. Changed so that -ifdef
?MODULE. will not consider ?MODULE defined if -module() has not
been previously seen.
* compiler: In a guard, not (X =:= true) would incorrectly
evaluate to false for non-boolean values of X.
* compiler: When the deterministic option was given to the
compiler, the ?FILE macro would be expanded to full path of the
source file before the first include directive and to base part
of the filename after include directive.
* public_key: public_key:pkix_sign/2 now honors the salt length
from the provided input parameters. Earlier this could result
in incorrect signatures if not using recommended defaults.
* public_key: When decoding an 'ECPrivateKey' unwrap the private
key. For more precise information see RFC 8410, section 7.
* runtime_tools: Observer now has a sectiion for new socket.
* runtime_tools: The dbg docs have been expanded to include the
meaning of all the function name acronyms.
* megaco: It is now possible to configure the built-in transports
(megaco_tcp and megaco udp) to use the new (gen_udp- and
gen_tcp-) option 'inet_backend'.
* crypto: Fix bug in crypto:ensure_engine_unloaded. Also fixed
minor memory leak related to engine unloading.
* crypto: Fixes that FIPS enable and disable (or vice versa) on
Windows sometimes leads to core dump at the time of process
exit.
* crypto: Disable fips if cryptolib < 1.0.1 and OTP/crypto is
configured with --enable-fips If not, there could be compiling
or loading problems with antique OpenSSL versions.
* jinterface: Fixed rare race bug that could cause
NullPointerException on local close of connection.
- Changes for 24.0.6:
* erts: A call to the process_info() BIF could end up hanging for
ever due to a bug introduced when the new selective receive
optimization was introduced in OTP 24.0. Note that this bug
only effects process_info().
* erts: Fix buffer overrun problem in the tty driver. The problem
happens on some platforms when using the CTRL+R functionality
of newshell with very long strings in the history.
* erts: Fix race-condition that could cause a crash when tracing
scheduling or garbage collections on a process that was running
on a dirty scheduler.
* erts: Fix rare bug where re:run would crash/return invalid
results when given a subbinary as subject. This bug has existed
since Erlang/OTP 20.0.
* erts: binary_to_term/1,2 is now more resilient against
corrupted binaries containing maps in the external format. - Added hardening to systemd service(s) (bsc#1181400). Modified:
* epmd.service - Changes for 24.0.5:
* kernel: For gen_tcp:connect/3,4 it is possible to specify a
specific source port, which should be enough to bind the socket
to an address with that port before connecting. Unfortunately
that feature was lost in OTP-17216 that made it mandatory to
specify the source address to get an address binding, and
ignored a specified source port if no source address was
specified. That bug has now been corrected.
- Changes for 24.0.4:
* stdlib: Fix a bug that could cause a crash when formatting
tuples using the control sequences p or P and limiting the
output with the option chars_limit.
* ssl: Handle cross-signed root certificates when old root
expired as reported in GH-4877.
* ssl: The signature selection algorithm has been changed to also
verify if the client supports signatures using the elliptic
curve of the server's public/private key pair. This change
fixes #4958.
* ssl: Slight optimization of certificate decoding.
* public_key: Handle cross-signed root certificates when old root
expired as reported in GH-4877.
* common_test: An incoming NETCONF notification received before a
call to ct_netconfc:create_subscription/* caused the connection
process to fail with badarg. Unexpected notifications are now
logged in the same way as other unexpected messages.
* common_test: Add 'receiver' option to ct_netconfc To allow a
destination for incoming NETCONF notifications to be specified
at sessions creation. Previously, a caller of
create_subscription/* became the destination, but RFC 5277
create-subscription is no longer the only way in which NETCONF
notifications can be ordered. - Fix more directories not owned by the package (boo#1187546) - Changes for 24.0.3:
* erts: A call to erlang:cancel_timer(_, [{info, false}]) could
cause the calling process to block forever in the call. Note
that only the synchronous version of the call (that is, the
async option is false) in combination with the info option set
to false was effected by this bug.
* erts: Microstate accounting (msacc) and os:perf_counter()
unintentionally used system time instead of monotonic time for
time measurements on a lot of systems. These systems were all
non x86/x86_64 systems or x86/x86_64 systems without a reliable
and constant rdtsc instruction. The lock counting (lcnt) built
runtime system also unintentionally used system time instead of
monotonic time for time measurements on all systems.
* erts: Simultaneous calls to
erlang:system_flag(schedulers_online, _) could cause callers to
end up in a suspended state forever.
* dialyzer: Do not expose line number 0 in messages if there are
other locations to use.
* dialyzer: In rare circumstances, Dialyzer could crash analyzing
code with a list comprehension whose value was ignored. (Thanks
to Ulf Wiger for reporting this bug.)
* ssh: Filter out sensitive data (passwords etc) from progress
reports and supervisor reports.
* inets: Improved user input handling in inets/mod_esi preventing
unnecessary atom creation.
* compiler: A compiler optimization pass could crash when given
odd but legal code using throw/1.
- Changes for 24.0.2:
* kernel: Fix a race condition in Global.
* kernel: After a node restart with init:restart/0,1, the module
socket was not usable because supporting tables had been
cleared and not re-initialized. This has now been fixed.
Handling of the "." domain as a search domain was incorrect and
caused a crash in the DNS resolver inet_res, which has now been
fixed.
* kernel: Handling of combinations of the fd option and binding
to an address has been corrected, especially for the local
address family.
* kernel: Bug fixes and code cleanup for the new socket
implementation, such as: Assertions on the result of
demonitoring has been added in the NIF code, where appropriate.
Internal state handling for socket close in the NIF code has
been reviewed. Looping over close() for EINTR in the NIF code
has been removed, since it is strongly discouraged on Linux and
Posix is not clear about if it is allowed. The inet_backend
temporary socket option for legacy gen_tcp sockets has been
documented. The return value from net:getaddrinfo/2 has been
corrected: the protocol field is now an atom(), instead of,
incorrectly, list(atom()). The documentation has also been
corrected about this return type. Deferred close of a
socket:sendfile/* file was broken and has been corrected. Some
debug code, not enabled by default, in the socket NIF has been
corrected to not accidentally core dump for debug printouts of
more or less innocent events.
* stdlib: Fix a bug that could cause a loop when formatting terms
using the control sequences p or P and limiting the output with
the option chars_limit.
* erts: Not yet handled alias-message signals in the signal queue
at the time when a garbage collection was performed could cause
a memory corruption which in turn could result in a crash of
the runtime system. This bug was introduced in OTP 24.0.
* erts: Fixed bug when using external pids/ports in keys of big
maps (> 32). Could cause runtime crash. Bug exists since OTP
24.0.
* erts: After a node restart with init:restart/0,1, the module
socket was not usable because supporting tables had been
cleared and not re-initialized. This has now been fixed.
Handling of the "." domain as a search domain was incorrect and
caused a crash in the DNS resolver inet_res, which has now been
fixed.
* erts: A call to port_command() could cause a scheduler to end
up in an eternal loop if the port was busy and the calling
process had incoming signals at the time of the call. This bug
was introduced in OTP 23.3.2 (ERTS version 11.2.1), OTP
22.3.4.18 (ERTS version 10.7.2.10), and OTP 21.3.8.23 (ERTS
version 10.3.5.18).
* erts: Bug fixes and code cleanup for the new socket
implementation, such as: Assertions on the result of
demonitoring has been added in the NIF code, where appropriate.
Internal state handling for socket close in the NIF code has
been reviewed. Looping over close() for EINTR in the NIF code
has been removed, since it is strongly discouraged on Linux and
Posix is not clear about if it is allowed. The inet_backend
temporary socket option for legacy gen_tcp sockets has been
documented. The return value from net:getaddrinfo/2 has been
corrected: the protocol field is now an atom(), instead of,
incorrectly, list(atom()). The documentation has also been
corrected about this return type. Deferred close of a
socket:sendfile/* file was broken and has been corrected. Some
debug code, not enabled by default, in the socket NIF has been
corrected to not accidentally core dump for debug printouts of
more or less innocent events.
* erts: Dirty execution of a process in combination with an
unlink signal from a port to the process could cause the signal
queue of the process to enter into an inconsistent state. The
result of the inconsistency typically caused a crash of the
runtime system. This bug was introduced in OTP 23.3 (ERTS
version 11.2).
* erl_docgen: Fix links generated in specs to types in other
applications to point to the correct place. This bug was
introduced in Erlang/OTP 24.0.
* ssl: Fix cache invalidation problem for CA certs provided by
the cacertfile option.
* ssh: Avoid an extra blank line in the ssh known_hosts file
* compiler: Fixed a bug that could cause after blocks to be
ignored when erlang:raise/3 was used in a catch block.
* compiler: Fixed a bug in the validation pass that could cause
it to reject valid code.
* crypto: EC keys are now zero-padded to the expected length if
needed. - Use sysusers-tools to provide epmd user
- Fix directories not owned by the package (boo#1187546) - Install RPM macros file to %{_rpmmacrodir} (boo#1185667) - Changes for 24.0.1:
* erl_interface: Commit of generated configure script.
* wx: Fix build problems when wxWidgets are built with -enable-
std.
* wx: Commit of generated configure script.
* crypto: Removed a risk for coredump.
* crypto: Fixed and documented the DED_LDFLAGS_CONFTEST
configuration variable in $ERL_TOP/HOWTO/INSTALL.md.
* crypto: Commit of generated configure script.
* common_test: Commit of generated configure script.
* ssh: Add missing known_hosts and authorized_keys file types to
ssh_file:decode/2 and ssh_file:encode/2.
* erts: Commit of generated configure script.
* snmp: Commit of generated configure script.
* megaco: Commit of generated configure script.
* odbc: Commit of generated configure script. - Version 24.0:
- Highlights compiler:
* The compiler will now inline funs that are used only once
immediately after their definition.
* Compiler warnings and errors now include column numbers in
addition to line numbers.
* Variables bound between the keywords 'try' and 'of' can now
be used in the clauses following the 'of' keyword (that is,
in the success case when no exception was raised).
* Generators in list and binary comprehensions will now raise a
{bad_generator,Generator} exception if the generator has an
incorrect type Similarly, when a filter does not evaluate to
a boolean, a {bad_filter,Filter} exception will be raised.
* Warnings for expressions whose result was ignored that could
be suppressed by using the anonymous variable '_' can now be
suppressed with a variable beginning with '_'.
* Selective receive optimization will now be applied much more
often. The new recv_opt_info compile flag can be used to
print diagnostics relating to this optimization. You can read
more about the selective receive optimization in the
Efficiency Guide.
- erts, kernel, stdlib:
* hex encoding and decoding functions added in the binary module
* The BeamAsm JIT-compiler has been added to Erlang/OTP and
will give a significant performance boost for many
applications. The JIT-compiler is enabled by default on most
x86 64-bit platforms that have a C++ compiler that can
compile C++17. To verify that a JIT enabled emulator is
running you can use erlang:system_info(emu_flavor).
* A compatibility adaptor for gen_tcp to use the new socket API
has been implemented (gen_tcp_socket).
* Extended error information for failing BIF calls as proposed
in EEP 54 has been implemented.
* Process aliases as outlined by EEP 53 has been introduced.
* Implementation of EEP 56 in supervisor. It adds the concept
of significant children as well as the auto_shutdown
supervisor flag. See the supervisor manual page for more
information.
- ftp:
* Add support for FTPES (explicit FTP over TLS).
- ssl:
* Make TLS handshakes in Erlang distribution concurrent.
* TLS connections now support EdDSA certificates.
- wx:
* The application has been completely rewritten in order to use
wxWidgets version 3 as its base.
* Added support for wxWebView.
- edoc:
* EDoc is now capable of emitting EEP-48 doc chunks. This means
that, with some configuration, community projects can now
provide documentation for shell_docs the same way that OTP
libraries did since OTP 23.0. - Pack doc/chunks into %{_libdir} (boo#1184492) - Use wxWidgets < 3.1 (boo#1180488) - Changes for 23.2.2:
* crypto: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* odbc: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* snmp: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* erts: The suspend_process() and resume_process() BIFs did not
check their arguments properly which could cause an emulator
crash.
* erts: The runtime system would get into an infinite loop if the
runtime system was started with more than 1023 file descriptors
already open.
* megaco: Fixed usage of AC_CONFIG_AUX_DIRS() macros in configure
script sources.
* erl_interface: Integers outside of the range [-(1 bsl 32) - 1,
(1 bsl 32) -1] were previously intended to be printed in an
internal bignum format by ei_print_term() and
ei_s_print_term(). Unfortunately the implementation has been
buggy since OTP R13B02 and since then produced results with
random content which also could crash the calling program. This
fix replaces the printing of the internal format with printing
in hexadecimal form and extend the range for printing in
decimal form. Currently integers in the range [-(1 bsl 64), (1
bsl 64)] are printed in decimal form and integers outside of
this range in Erlang hexadecimal form.
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation
on the external term format larger than 2 GB cannot be handled.
* ssl: Fix CVE-2020-35733 this only affects ssl-10.2 (OTP-23.2).
This vulnerability could enable a man in the middle attack
using a fake chain to a known trusted ROOT. Also limits
alternative chain handling, for handling of possibly extraneous
certs, to improve memory management.
* ssl: Add support for AES CCM based cipher suites defined in RFC
7251 Also Correct cipher suite name conversion to OpenSSL
names. A few names where corrected earlier in OTP-16267 For
backwards compatible reasons we support usage of openSSL names
for cipher suites. Mostly anonymous suites names where
incorrect, but also some legacy suites.
- Changes for 23.2.1:
* erts: Fix emulator crash when sending small bit-strings over
Erlang distribution while the connection is being setup. The
fault was introduced in OTP-23.0
- Changes for 23.2:
* erl_docgen: Fix links in titles to github and anchors to work.
* erl_docgen: Fix some typing errors on variable names in
documentation examples.
* mnesia: Avoid potential performance issue, if the input queue
to mnesia_tm is long.
* crypto: Build the supported curves cache in the NIF when crypto
is loaded, no matter how it is loaded. This prevents a possible
problem with different processes starting the crypto
application concurrently.
* crypto: It is now possible to build with crypto and openssl
gprof-enabled and statically link them into the VM.
* crypto: Fixed performance loss in HMAC when using older OpenSSL
due to mutex issues. A workaround is implemented to allow
fallback from using the EVP API for HMAC operations. On some
architectures this may improve the performance, especially with
old OpenSSL versions. This fallback to low-level functions is
always enabled for openssl versions before 1.0.2.
* kernel: The apply call's in logger.hrl are now called with
erlang prefix to avoid clashed with local apply/3 functions.
* kernel: Fix memory leak in pg.
* kernel: Fix crash in logger_proxy due to stray gen_server:call
replies not being handled. The stray replies come when logger
is under heavy load and the flow control mechanism is reaching
its limit.
* kernel: Fixed a bug in erl_epmd:names() that caused it to
return the illegal return value noport instead of {error,
Reason} where Reason is the actual error reason. This bug also
propagated to net_adm:names(). This bug was introduced in
kernel version 7.1 (OTP 23.1).
* kernel: Add export of some resolver documented types.
* kernel: Add configurable retry timeout for resolver lookups.
* kernel: gen_server:multi_call() has been optimized in the
special case of only calling the local node with timeout set to
infinity.
* public_key: Corrected dialyzer spec for pkix_path_validation/3
* snmp: If an attempt was made to send a v1 trap on a IPv6
transport this could cause a master agent crash (if the agent
was *not* multi-threaded).
* snmp: The deprecation info for a couple of the deprecated MIB
compiler functions where incorrect. Referred to functions in
the 'snmpa' module instead of 'snmpc'.
* snmp: Make it possible for the agent to configure separate
transports (sockets) for request-responder and trap-sender.
* snmp: The mib server cache handling has been improved. First,
the default gclimit has been changed from 100 to infinity (to
ensure the size is as small as possible). Also, the method of
removing old elements has been optimized.
* snmp: It is now possible to configure the agent in such a way
that the order of outgoing notifications are processed in order
in the agent. What happens after the notification message has
left the agent (been sent) is of course still out of our
control.
* snmp: Improve handling of the udp_error message. Basically an
improved error/warning message.
* wx: Add popup menu callback to wxTaskBarIcon:new/1.
* dialyzer: Clarify warning option -Wunmatched_returns in
dialyzer(3).
* tools: Correct the Xref analysis exports_not_used to not report
internally generated behaviour_info/1.
* syntax_tools: In the syntax_tools application, the igor module
and all functions in erl_tidy except file/2 have been
deprecated.
* compiler: Several minor compiler bugs have been fixed:
Constructing a binary with a list as a size of a binary segment
could generate a BEAM file that could not be loaded. When
matching a binary segment of type float and ignoring the
matched out value, the match would always succeed, even if the
size was invalid or the value of the float was NaN or some
other non-numeric float value. Attempting to construct an
invalid external fun (e.g. fun m:f:bad) is supposed to raise a
'badarg' exception, but if the value was never used, no
exception would be raised.
* compiler: Fixed multiple bugs in the validator that could cause
it to reject valid code.
* compiler: The compiler could crash when a binary comprehension
had a generator that depended on another generator.
* compiler: Fixed a bug in the type optimization pass that could
yield incorrect values or cause the wrong clauses to be
executed.
* erts: Fixed bug which could cause VM crash when a NIF is loaded
at the same time as the Erlang implementation of the NIF is
called. Bug exists since OTP 23.0.
* erts: Fixed enif_make_map_* functions in debug build when given
environment from enif_alloc_env.
* erts: Fixed broken configuration option --disable-pie.
* erts: Fixed rare distribution bug in race between received
signal (link/monitor/spawn_request/spawn_reply) and
disconnection. Symptom: VM crash. Since: OTP 21.0.
* erts: Fixed a performance issue when extremely many items were
stored in the process dictionary. (Fixing this bug also
eliminates a compiler warning emitted by the latest version of
Clang.)
* erts: Remove -ftree-copyrename from flags passed to compiler
when building erts. The flag is not used by modern gcc's and is
not supported by clang.
* erts: Modules using complicated nested binary comprehensions
could fail to load.
* erts: Fixed a race in file:read_file/1 were an incomplete file
could be returned if another OS process swapped the file out
while reading.
* erts: The call list_to_integer("10", true) would return 4
instead of raising an exception. Certain other atoms would also
be interpreted as a number base.
* erts: On macOS 11 (Big Sur), erl would not start if the maximum
number of file descriptors were unlimited (ulimit -n
unlimited).
* erts: Add manifest to all executables and dynamic libraries.
* xmerl: Corrected namespace and expanded name in the old dom
backend example module.
* xmerl: Corrected a bug that in some cases didn't allow
unresolved references when skip_external_dtd option used.
* ssh: Fixed problems in the ssh cli/shell handling. Most
important are: 1) the ssh:shell function did sometimes cause
the input to be echoed twice, 2) the ssh:shell function didn't
transfer the LANG and LC_ALL shell variables to the connected
server which sometimes made Unicode handling erroneous, 3)
Unicode was not always transferred correctly to and from the
peer.
* ssh: The SSH protocol message SSH_MSG_DISCONNECT was sometimes
sent instead of SSH_MSG_CHANNEL_FAILURE
* ssh: The ssh_cli module now always sends the exit-status to
connected clients so they can use that to check for successful
command execution.
* ssh: A new option pk_check_user enables checking of the
client's user name in the server when doing public key
authentication.
* stdlib: This change fixes the handling of deep lists in the
path component when using uri_string:recompose/1.
* stdlib: Fix shell_docs to clear shell decorations
(bold/underline) when paginating output. Fix various small
renderings issues when integrating shell_docs with edoc.
* stdlib: Improved the API and documentation of the uri_string
module. Added a new chapter to the Users Guide about Uniform
Resource Identifiers and their handling with the new API. Added
two new API functions: uri_string:allowed_characters/0 and
uri_string:percent_decode/1. This change has been marked as
potentially incompatible as uri_string:normalize/2 used to
decode percent-encoded character triplets that corresponded to
characters not in the reserved set. After this change,
uri_string:normalize/2 will only decode those percent-encoded
triplets that correspond to characters in the unreserved set
(ALPHA / DIGIT / "-" / "." / "_" / "~"). *** POTENTIAL
INCOMPATIBILITY ***
* stdlib: The shell_docs module has been expanded with the
possibility to configure unicode, ansi and column size for the
rendered text.
* megaco: Empty statistics descriptor (now) allowed in both
encode and decode for version 3.
* ssl: SSL's Erlang Distribution Protocol modules inet_tls_dist
and inet6_tls_dist lacked a callback function, so the start
flag "-dist_listen false" did not work, which has now been
fixed.
* ssl: Correct OpenSSL names for newer cipher suites using DHE in
their name that accidentally got the wrong value when fixing
other older names using EDH instead.
* ssl: This change improves the handling of DTLS listening
dockets, making it possible to open multiple listeners on the
same port with different IP addresses.
* ssl: Fix a bug that causes cross-build failure. This change
excludes the ssl.d dependency file from the source tarballs.
* ssl: This change fixes ssl:peername/1 when called on a DTLS
client socket.
* ssl: Retain emulation of active once on a closed socket to
behave as before 23.1
* ssl: Corrected server session cache entry deletion pre TLS-1.3.
May increase session reuse.
* ssl: Handle extraneous certs in certificate chains as well as
chains that are incomplete but can be reconstructed or
unordered chains. The cert and certfile options will now accept
a list of certificates so that the user may specify the chain
explicitly. Also, the default value of the depth option has
been increased to allow longer chains by default.
* ssl: This change implements optional NSS-style keylog in
ssl:connection_information/2 for debugging purposes. The keylog
contains various TLS secrets that can be loaded in Wireshark to
decrypt TLS packets.
* ssl: Use new gen_statem feature of changing callback mode to
improve code maintainability.
* ssl: The handling of Service Name Indication has been aligned
with RFC8446.
* ssl: Add explicit session reuse option to TLS clients for pre
TLS-1.3 sessions. Also, add documentation to Users Guide for
such sessions.
* inets: Fix an issue about HTML-escaped filename in inets.
* common_test: Add behaviour for test suites
- Changes for 23.1.5:
* ssh: An ssh-client can take an accepted socket from a listening
socket and do an ssh:connect/2 on it. Multiple clients on
sockets accepted from the same listening socket had stopped
working. This is corrected now.
- Changes for 23.1.4:
* ssh: The inet option raw was not passed on from the ssh option
list to inet. - Changes for 23.1.3:
* erts: Fixed a crash when exceptions were thrown during call
time tracing.
* ssh: A supervisor sub-tree could be left if the connection
handler process is brutally killed. This will make the
max_sessions checking option to count the existing sessions
erroneously and could finally block further sessions.
- Changes for 23.1.2:
* compiler: Fixed a bug in the boolean optimization pass that
caused the compiler to confuse different clauses.
* erts: Fixed bugs causing issues when enabling the ERTS internal
allocators on a system built with the undocumented and
unsupported SMALL_MEMORY feature.
* erts: The inet driver used to use 16 as maximum elements in an
I/O vector passed to writev() (and WSASend() on Windows). When
the data to send contained lots of elements, this caused a
performance degradation since repeated calls to writev() had to
be made to a much larger extent. The inet driver now looks up
actual maximum amount of elements that can be used on the
system, instead of just assuming 16. On most systems this will
result in a maximum amount of I/O vector elements of 1024. As
of OTP 23.0 the term encoding of signals to send over the
distribution are encoded into I/O vectors of buffers instead of
into a single buffer. Reference counted binaries are referred
to directly from the I/O vector instead of being copied into
the single buffer. That is, Erlang signals containing huge
amounts of reference counted binaries was effected by this
performance degradation.
* erts: In the distributed case, a faulty reply option in a call
to the spawn_request() BIF erroneously caused a badarg
exception instead of a badopt error message reply. - Changes for 23.1.1:
* erts: inet:setopts([{active,once}]) wakes up IO polling thread
unnecessarily, leading to lock contention and visibly higher
CPU utilization.
* erts: Two bugs in the ERTS internal thread wakeup functionality
have been fixed. These bugs mainly hit when all threads in the
system tried to go to sleep. When the bugs were triggered,
certain operations were delayed until a thread woke up due to
some other reason. Most important operations effected were code
loading, persistent term updates, and memory deallocation.
* erts: Fixed bug in ets:select_replace/2 on compressed tables
that could produce faulty results or VM crash. Bug exists since
OTP 20.
* erts: When compiling Erlang/OTP on macOS using Xcode 12, the
performance of the BEAM interpreter would be degraded.
* erts: As of OTP 22, the allocator specific memory carrier pools
were replaced by a node global carrier pool. This unfortunately
caused substantial memory fragmentation in some cases due to
long lived data being spread into carriers used by allocators
mainly handling short lived data. A new command line argument
+Mcp has been introduced with which one can enable the old
behavior as well as configuring other behaviors for the carrier
pools. In order to configure the old behavior, with allocator
specific carrier pools for all allocators, pass +Mucp :
(including the colon character) as a command line argument to
erl when starting the Erlang system. The default configuration
for carrier pools will be changed to +Mucp : some time in the
future, but not in this patch.
* os_mon: The configuration parameter
memsup_improved_system_memory_data has been introduced. It can
be used to modify the result returned by
memsup:get_system_memory_data(). For more information see the
memsup documentation. Note that the configuration parameter is
intended to be removed in OTP 24 and the modified result is
intended to be used as of OTP 24.
* ssh: Fix decoder bug.
* compiler: Fixed a performance bug that could be triggered by
tuple matching in very large functions.
* public_key: Fix the issue that pem_decode will crash with an
invalid input.
- Changes for 23.1:
* kernel: A fallback has been implemented for file:sendfile when
using inet_backend socket
* kernel: Make default TCP distribution honour option backlog in
inet_dist_listen_options.
* kernel: Raw option handling for the experimental gen_tcp_socket
backend was broken so that all raw options were ignored by for
example gen_tcp:listen/2, a bug that now has been fixed.
Reported by Jan Uhlig.
* kernel: Accept fails with inet-backend socket.
* kernel: Fixed various minor errors in the socket backend of
gen_tcp.
* kernel: Correct disk_log:truncate/1 to count the header. Also
correct the documentation to state that disk_log:truncate/1 can
be used with external disk logs.
* kernel: Fix erl_epmd:port_please/2,3 type specs to include all
possible error values.
* kernel: Fix erl -erl_epmd_port to work properly. Before this
fix it did not work at all.
* kernel: Fix typespec for internal function
erlang:seq_trace_info/1 to allow term() as returned label. This
in turn fixes so that calls to seq_trace:get_token/1 can be
correctly analyzer by dialyzer.
* kernel: Fix erroneous double registration of processes in pg
when distribution is dynamically started.
* kernel: Make (use of) the socket registry optional (still
enabled by default). Its now possible to build OTP with the
socket registry turned off, turn it off by setting an
environment variable and controlling in runtime (via function
calls and arguments when creating sockets).
* kernel: erl -remsh nodename no longer requires the hostname to
be given when used together with dynamic nodenames.
* observer: Fix graph windows flickering on windows.
* mnesia: FIx mnesia delete object handling in transaction
storage. In a transaction mnesia:read/1 could indicate that
exiting objects did not exist after another object was deleted.
* mnesia: Fixed crash during startup, which could happen if a
table was deleted on another node.
* stdlib: The functions digraph:in_edges/2 and
digraph:out_edges/2 would return false edges if called for a
vertex that had a '_' atom in its name term.
* stdlib: filelib:wildcard("not-a-directory/..") should return an
empty list. On Windows it returned "not-a-directory/..".
* stdlib: Fix the typespec of shell_docs:render to use the
correct type for an MFA.
* stdlib: Fix uri_string:recompose/1 when host is present but
input path is not absolute. This change prevents the recompose
operation to change the top level domain of the host when the
path does not start with a slash.
* stdlib: The epp module would return a badly formed error term
when an 'if' preprocessor directive referenced an undefined
symbol. epp:format_error/1 would crash when called with the bad
error term.
* stdlib: lists:sublist(List, Start, Len) failed with an
exception if Start > length(List) + 1 even though it is
explicitly documented that "It is not an error for Start+Len to
exceed the length of the list".
* tools: Correct the Xref analysis locals_not_used to find
functions called exclusively from on_load functions.
* erts: Update the documentation of the abstract format to use
ANNO instead of LINE.
* erts: The emulator will no longer revert to the default number
of schedulers when running under a CPU quota lower than 1 CPU.
* erts: Fixed a problem with crash dumps. When a process that
contained reference to literals internally created by the
runtime system (such as the tuple returned by os:type/0), the
literal would not be included in the crash dump and the
crashdump viewer would complain about the heap being
incomplete.
* erts: Fix configure detection of PGO for clang.
* erts: The to_erl program has been fixed to correctly interpret
newline as only newline and not newline+return. This bug would
cause the terminal to behave strangely when using lines longer
than the terminal size.
* erts: A race condition when changing process priority by
calling process_flag(priority, Prio) could cause elevation of
priority for a system task to be ignored. This bug hit if the
system task was scheduled on the process calling process_flag()
at the same time as the priority was changed. The bug is quite
harmless and should hit very seldom if ever.
* erts: Adjust /bin/sh to /system/bin/sh in scripts when
installing on Android.
* erts: In rare circumstances, when loading a BEAM file generated
by an alternative code generator (not the Erlang compiler in
OTP) or from handwritten or patched BEAM code, the loader could
do an unsafe optimization.
* erts: A memory and file descriptor leak in socket has been
fixed. (When a newly opened socket that had not entered the fd
into the VM's poll set (neither received, sent, accepted nor
connected) was abandoned without closing (process died), after
assigning a different controlling process, then a memory block
and the file descriptor could be leaked.)
* erts: The documentation of statistics(run_queue) erroneously
stated that it returns the total length of all normal run
queues when it is the total length of all normal and dirty CPU
run queues that is returned. The documentation has been updated
to reflect the actual behavior.
* erts: Changes in order to build on the Haiku operating system.
Thanks to Calvin Buckley
* erts: When building the inet driver on Windows, there where
many compiler warnings regarding type casting (used when
calling the debug macro). This has now been resolved.
* erts: Make (use of) the socket registry optional (still enabled
by default). Its now possible to build OTP with the socket
registry turned off, turn it off by setting an environment
variable and controlling in runtime (via function calls and
arguments when creating sockets).
* erts: Change default filename encoding on android to UTF-8.
* erts: Clarification of the format of the atom cache header used
by the distribution.
* erl_docgen: Repaired lost function "since" versions in the
right margin of the module reference HTML documentation.
* erl_docgen: Remove erlang compilation warnings and trailing
whitespaces.
* ftp: Avoid timing issue when setting active once on a socket
that is being closed by the peer.
* ftp: Avoid timing issue when setting active once on a socket
that is being closed by the peer.
* dialyzer: In rare circumstance, dialyzer wold crash when
analyzing a list comprehension.
* eunit: Fixed compiler warning.
* snmp: For agent fix PrivParams for SNMPv3 USM with AES privacy,
as earlier fixed for the manager in OTP_16541.
* snmp: The SNMP Agent missed to re-activate datagram reception
in an odd timeout case and went deaf. This bug has been fixed.
* snmp: Use of deprecated functions in example 2 has been removed
(no more compiler warnings).
* snmp: A file descriptor leak has been plugged. When calling the
reconfigure function of a mib, it opened the config file(s) but
never closed them on successful read.
* asn1: Changes in order to build on the Haiku operating system.
Thanks to Calvin Buckley
* syntax_tools: Minor documentation fix of erl_syntax:operator/1.
* erl_interface: Fix erl_interface on windows to be compiled with
correct flags to make internal primitives reentrant.
* erl_interface: Fixed ei_get_type to set *size to zero for
floats, pids, port and refs according to documentation.
* erl_interface: Fix ei_connect when using a dynamic node name to
force usage of distribution version 6. This bug caused erl_call
- R -address to not work properly.
* erl_interface: Changes in order to build on the Haiku operating
system. Thanks to Calvin Buckley
* erl_interface: The ei API for decoding/encoding terms is not
fully 64-bit compatible since terms that have a representation
on the external term format larger than 2 GB cannot be handled.
* ssl: If a passive socket is created, ssl:recv/2,3 is never
called and then the peer closes the socket the controlling
process will no longer receive an active close message.
* ssl: Data deliver with ssl:recv/2,3 could fail for when using
packet mode. This has been fixed by correcting the flow control
handling of passive sockets when packet mode is used.
* ssl: This change fixes a potential man-in-the-middle
vulnerability when the ssl client is configured to
automatically handle session tickets ({session_tickets, auto}).
* ssl: Fix the internal handling of options 'verify' and
'verify_fun'. This change fixes a vulnerability when setting
the ssl option 'verify' to verify_peer in a continued handshake
won't take any effect resulting in the acceptance of expired
peer certificates.
* ssl: This change fixes the handling of stateless session
tickets when anti-replay is enabled.
* ssl: Fix a crash due to the faulty handling of stateful session
tickets received by servers expecting stateless session
tickets. This change also improves the handling of
faulty/invalid tickets.
* ssl: Correct flow ctrl checks from OTP-16764 to work as
intended. Probably will not have a noticeable affect but will
make connections more well behaved under some circumstances.
* ssl: Distribution over TLS could exhibit livelock-like
behaviour when there is a constant stream of distribution
messages. Distribution data is now chunked every 16 Mb to avoid
that.
* ssl: Implement the cookie extension for TLS 1.3.
* ssl: Experimental OCSP client support.
* ssl: TLS 1.0 -TLS-1.2 sessions tables now have a absolute max
value instead of using a shrinking mechanism when reaching the
limit. To avoid out of memory problems under heavy load
situations. Note that this change infers that implementations
of ssl_session_cache_api needs to implement the size function
(introduce in OTP 19) for session reuse to be optimally
utilized.
* os_mon: memsup now returns the correct amount of system memory
on macOS.
* os_mon: Fix memsup:get_os_wordsize/0 to return the current size
on aarch64.
* ssh: Fixed a bug when a message to ssh-agent was divided into
separate packets.
* ssh: Fix a bug that could crash the cli server if a too large
cli-window was requested from the client.
* ssh: Increased test coverage.
* ssh: A chapter about hardening the OTP SSH is added to the
User's Guide.
* ssh: The internal Diffie-Hellman high level API for key
generation was slow in old and by OpenSSL now unsupported
cryptolib versions (1.0.1 and earlier). If such a cryptolib is
used anyhow, the low-level API is used internally in the crypto
application.
* ssh: A new timeout is defined for daemons: hello_timeout. The
timeout is supposed to be used as a simple DoS attack
protection. It closes an incoming TCP-connection if no valid
first SSH message is received from the client within the
timeout limit after the TCP initial connection setup. The
initial value is 30s by compatibility reasons, but could be
lowered if needed, for example in the code or in a config file.
* inets: Clarify the handling of percent encoded characters in
http client.
* inets: fix crash for undefined port in uri.
* inets: Avoid timing issue when setting active once on a socket
that is being closed by the peer.
* inets: Handle message body of response with 1XX status code as
next http message.
* inets: Fix a crash in http server when setopts is called on a
socket closed by the peer.
* inets: A vulnerability in the httpd module (inets application)
regarding directory traversal that was introduced in OTP 22.3.1
and corrected in OTP 22.3.4.6. It was also introduced in OTP
23.0 and corrected in OTP 23.1 The vulnerability is registered
as CVE-2020-25623 (boo#1177354) The vulnerability is only exposed
if the http server (httpd) in the inets application is used. The
vulnerability makes it possible to read arbitrary files which
the Erlang system has read access to with for example a
specially prepared http request.
* inets: Add support of PATCH method in mod_esi.
* compiler: If the update of a map with the 'Map#{Key := Value}'
syntax failed, the line number in the stack backtrace could be
incorrect.
* compiler: Fixed a performance bug that slowed down compilation
of modules with deeply nested terms.
* compiler: The compiler could in rare circumstances do an an
unsafe optimization that would result in a matching of a nested
map pattern would fail to match.
* compiler: Fixed a bug in the validator that caused it to reject
valid code.
* public_key: Fixed an insignificant whitespace issue when
decoding PEM file.
* public_key: Experimental OCSP client support.
* public_key: Use user returned path validation error for
selfsigned cert. It allows users of the ssl application to
customize the generated TLS alert, within the range of defined
alerts.
* public_key: add API function to retrieve the subject-ID of an
X509 certificate
* runtime_tools: Fixed a crash in appmon_info triggered by trying
to read port info from a port that was in the process of
terminating. appmon_info is used by observer to get information
from the observed node.
* megaco: The expected number of warnings when (yecc) generating
v2 and v3 (text) parser's was incorrect.
* hipe: Fixed a warning issued when building the hipe
application.
* odbc: Changes in order to build on the Haiku operating system.
Thanks to Calvin Buckley
* crypto: Fix type spec bug in crypto for crypto_init and
crypto:one_time
* crypto: The deprecation message for crypto:rand_uniform/2
indicated a non-existent function. The correct one
(rand:uniform/1) is now suggested.
* crypto: Implemented a workaround to allow fallback from using
the EVP API for Diffie-Hellman key generation
* crypto: The internal Diffie-Hellman high level API for key
generation was slow in old and by OpenSSL now unsupported
cryptolib versions (1.0.1 and earlier). If such a cryptolib is
used anyhow, the low-level API is used internally in the crypto
application.
* sasl: Make release_handler more resilient against exiting
processes during upgrade.
- Changes for 23.0.4:
* stdlib: When a temporary child of a simple_one_for_one
supervisor died, the internal state of the supervisor would be
corrupted in a way that would cause the supervisor to retain
the start arguments for subsequent children started by the
supervisor, causing unnecessary growth of the supervisor's
heap. There state corruption could potentially cause other
problems as well.
* erts: The ERTS internal I/O poll implementation could get into
an inconsistent state causing input events to be ignored.
* megaco: The v2 and v3 parsers could not properly decode some
IPv6 addresses. - Changes for 23.0.3:
* erts: Fixed bug in erlang:load_nif/2 that could cause it to
throw badarg exception if a concurrent code change operation
was in progress. Bug existed since OTP 23.0.
* erts: Minor fix of debug compiled VM.
* erts: An unintentional reuse of an already used emulator
internal event object could cause a wakeup signal to a thread
to be lost. In worst case this could cause the runtime system
to hang. This hang was however quite rare.
* erts: NIF threads and driver threads on non-Linux systems
leaked internal resources when terminating. On Windows these
resources were one event per thread. On most other systems one
mutex and one condition variable per thread. On these other
systems that also lacked pthread_cond_timedwait() also a pipe
with its file descriptors was leaked.
* compiler: When calls to is_map_key were repeated, the compiler
could terminate with an internal consistency failure.
* compiler: Fixed a bug in the type inference pass that could
cause the compiler to hang. - Changes for 23.0.2:
* erts: Fixed bug when sending an export fun (eg lists:reverse/1)
on a not yet established connection. It could cause VM crash.
Bug exists since OTP 23.0.
* megaco: The mini parser could not properly decode some IPv6
addresses.
- Changes for 23.0.1:
* erts: The functionality utilized by BIFs for temporary
disabling of garbage collection while yielding could cause
system task queues to become inconsistent on a process
executing such a BIF. Process system tasks are for example
utilized when purging code, garbage collecting literal data,
and when issuing an ordinary garbage collection from another
process. The bug does not trigger frequently. Multiple code
purges in direct sequence makes it more likely that this bug is
triggered. In the cases observed, this has resulted in a
hanging code purge operation.
* erts: SCTP and UDP recv/2,3 hangs indefinitely if socket is
closed while recv is called (socket in passive mode).
* compiler: In rare circumstances, a guard using 'not' could
evaluate to the wrong boolean value.
* compiler: A guard expression that referenced a variable bound
to a boolean expression could evaluate to the wrong value. - Version 23.0:
- Potential Incompatibilities:
* SSL:Support for SSL 3.0 is completely removed. TLS 1.3 is added
to the list of default supported versions.
* erl_interface: Removed the deprecated parts of erl_interface
(erl_interface.h and essentially all C functions with prefix
erl_).
* The deprecated erlang:get_stacktrace/0 BIF now returns an empty
list instead of a stacktrace. erlang:get_stacktrace/0 is
scheduled for removal in OTP 24.
- Improvements and new features:
* ssh: OpenSSH 6.5 introduced a new file representation of keys
called openssh-key-v1. This is now supported with the exception
of handling encrypted keys.
* Algorithm configuration could now be done in a .config file. This
is useful for example to enable an algorithm that is disabled by
default without need to change the code.
* SSL: Support for the middlebox compatibility mode makes the TLS
1.3 handshake look more like a TLS 1.2 handshake and increases
the chance of successfully establishing TLS 1.3 connections
through legacy middleboxes.
* Add support for key exchange with Edward curves and PSS-RSA
padding in signature verification
* The possibility to run Erlang distribution without relying on
EPMD has been extended.
* A first EXPERIMENTAL socket backend to gen_tcp and inet has been
implemented. gen_udp and gen_sctp will follow.
* Putting {inet_backend, socket} as first option to listen() or
connect() makes it easy to try this for existing code
* A new module erpc in kernel which implements an enhanced subset
of the operations provided by the rpc module. Enhanced in the
sense that it makes it possible to distinguish between returned
value, raised exceptions and other errors. erpc also has better
performance and scalability than the original rpc implementation.
This by utilizing the newly introduced spawn_request() BIF. Also
the rpc module benefits from these improvements by utilizing erpc
when possible.
* Scalability and performance Improvements plus new functionality
regarding distributed spawn operations.
* In binary matching, the size of the segment to be matched is now
allowed to be a guard expression (EEP-52)
* When matching with maps the keys can now be guard expressions
(EEP-52).
* ssh: support for TCP/IP port forwarding, a.k.a tunnelling a.k.a
as tcp-forward/direct-tcp is implemented. In the OpenSSH client,
this corresponds to the options -L and -R.
* Allow underscores in numeric literals to improve readability.
Examples: 123_456_789, 16#1234_ABCD.
* New functions in the shell for displaying documentation for
Erlang modules, functions and types.
* kernel: The module pg with a new implementation of distributed
named process groups is introduced. The old module pg2 is
deprecated and scheduled for removal in OTP 24. - Changes for 22.3:
* compiler: A 'receive' with an 'after 0' clause would prevent
the optimization that can avoid scanning the entire receive
queue when matching on a newly created reference.
* compiler: HiPE can again handle modules with catch and try
constructs.
* compiler: Fixed a bug in bit-syntax optimization that could
crash the compiler.
* crypto: Fixed potential memory leaks involving calls to the
crypto ng_api.
* common_test: Document incl_apps cover option
* common_test: The ct_property_test has now a report function for
results of stateful testing.
* common_test: Don't hide error reasons from user
* stdlib: Fix type specification for uri_string:normalize/2 that
may also return error().
* stdlib: Improve error handling in uri_string:normalize/2. This
change fixes a crash when the input URI has faulty percent-
encoding.
* stdlib: Fix minor bugs in the Erlang pretty printer (erl_pp).
* stdlib: Fix the Erlang parser regarding consecutive unary
operators.
* stdlib: Let calendar:rfc3339_to_system_time() crash when the
time offset is missing.
* stdlib: Implement uri_string:resolve/{2,3} that can be used to
resolve a URI reference against a base URI.
* stdlib: In gen_statem it is now possible to change the callback
module for a running server. See gen_statem's documentation for
change_callback_module, push_callback_module, and
pop_callback_module.
* ssl: Correct handling of TLS record limit in TLS-1.3. The max
value differs from previous versions. Also the payload data max
record check was broken, that is record overflow problems could
occur if user sent large amounts of data.
* ssl: Correct close handling for DTLS
* ssl: Fix ssl:getstat/1-2 to also work for DTLS sockets
* ssl: Correct internal handling och socket active mode to avoid
reviving TCP data aimed for a downgraded TLS socket.
* ssl: When using the host name as fallback for SNI (server name
indication) strip a possible trailing dot that is allowed in a
host name but not in the SNI. Also if the server receives a SNI
with a trailing dot send an UNRECOGNIZED_NAME alert.
* ssl: Immediately remove session entries if handshake is
abruptly closed at transport level.
* ssl: Implementation of the key and initialization vector update
feature, and general hardening of TLS 1.3. There are
cryptographic limits on the amount of plaintext which can be
safely encrypted under a given set of keys. This change
enforces those limits by triggering automatic key updates on
TLS 1.3 connections.
* ssl: Add support for TLS 1.3 Session Tickets (stateful and
stateless). This allows session resumption using keying
material from a previous successful handshake.
* ssl: Add support for key exchange with Edward curves and PSS-
RSA padding in signature verification.
* megaco: The documented function
megaco:get_sdp_record_from_PropertGroup/2 was a wrapper for
megaco_sdp:get_sdp_record_from_PropertGroup/2 but did not
actually exist. This has now been fixed.
* megaco: Test suite completely reworked. Add (timestamp) utility
functions for debugging and testing.
* erl_interface: Fix link error "multiple definition of
`ei_default_socket_callbacks'" for gcc version 10 or when built
with gcc option -fno-common. Error exists since OTP-21.3.
* asn1: Fix 'DEFAULT' with 'OCTET STRING' and 'SEQUENCE OF
CHOICE' with extensions.
* erts: gen_udp:recv(S, N, 0) corrupted the internal state for
the socket so after receive with {active, once} it always
returned {error, timeout}, and wasted the received UDP packets.
This bug has now been fixed. Reported and pinpointed by
Alexander Petrovsky.
* erts: The atom esock_atom_user and esock_atom_kernel was never
actually created. This has now been corrected.
* erts: Fixed bug in socket module that could potentially lead to
scheduler deadlocks.
* erts: Fix bug causing VM crash if down or stop callback of a
NIF resource is called after the NIF module has been purged.
The fix will postpone unloading until all such resource objects
have been garbage collected.
* erts: Fixed bug in ets:update_counter/4, when called with an
invalid UpdateOp and a Key that does not exist, causing
ets:info(T,size) to return incorrect values. Bug exists since
OTP-19.0.2.
* erts: Fix potential heap corrupting bugs when a process calls a
BIF that blocks other normal schedulers and then writes to its
own heap without the main process lock. A NIF running on a
dirty scheduler trying to interact with such a process could
corrupt its heap. The fixed BIFs were related to code loading
and tracing.
* erts: Fixed bug in erlang:list_to_ref/1 when called with a
reference created by a remote note. Function list_to_ref/1 is
intended for debugging and not to be used in application
programs. Bug exist since OTP 20.0.
* erts: The prim_net nif (net/kernel) made use of an undefined
atom, notsup. This has now been corrected.
* erts: Corrected the valid range of the erl command line
argument +SDio from 0..1024 to
1..1024. +SDio 0 was erroneously allowed which just caused the
VM to crash on the first dirty I/O job scheduled.
* erts: Fix a crash when attempting to log faults when loading
files during early boot.
* erts: For socket, not all send and receive flags are supported
on all platforms. In order to (at least) simplify testing, the
socket:supports/0,1,2,3 functions has been extended with
send_flags and recv_flags items, which indicates what the
current platform can manage.
* erts: Add a "full featured" version of getifaddrs in the net
module.
* erts: The options busy_limits_port and busy_limits_msgq have
been added to the BIF erlang:open_port/2. The busy_limits_port
option can be used for controlling the busy state of a port
executing the spawn_driver or the fd_driver. The
busy_limits_msgq option can be used for controlling the busy
state of the port message queue.
* erts: A socket "registry" has been added making it possible to
list current open sockets.
* erts: The counters managed by the socket nif has been extended.
Their "size" has been increased from 32 bit to 64. Two max
package size (for read and write) has been added. And four
accept counters has been added.
* erts: Add gcc option -fno-common to detect accidental name
clashes of global variables.
* erts: New dynamic lock checker that verifies locking orders and
detects potential deadlock bugs in drivers and NIFs. Enabled
together with the old static lock checker (for ERTS internal
locks) in emulator started with -emu_type debug or built with
configuration option --enable-lock-checking.
* snmp: A simple supervision of the snmp manager net-if process
has been added. Also, a way to forcibly restart the net-if
process has been added. This could be useful if the net-if
process hangs for some reason.
* snmp: Misc documentation corrections
* mnesia: Fixed a timing issue in uninstall fallback
functionality.
* eunit: Backport of PR-2316: Strip control codes from
eunit_surefire output to avoid generation of invalid xml
* ssh: Unicode problems for ssh_sftp:write fixed.
* ssh: Changes to the internal api of the experimental ssh_dbg
tool.
* ssh: The new functions ssh:set_sock_opts/2 and
ssh:get_sock_opts/2 sets and reads option values for the
underlying TCP stream.
* hipe: HiPE can again handle modules with catch and try
constructs.
* hipe: When the return value for try/catch was ignored, the
native code compiler could crash.
* public_key: Add support for key exchange with Edward curves and
PSS-RSA padding in signature verification.
* diameter: Add the 'first' tuple to type diameter:peer_filter/0.
The filter was added in OTP-17.5.6.8 and OTP-18.3, but neither
release updated the type specification.
* tools: An Emacs warning due to lacking type in defcustom
declaration has been fixed.
* tools: Improve emacs indentation.
* tools: The cover tool could generate instrumented code for a
module that would cause warnings to be issued.
* tools: Fixed generated fprof analysis format to also handle
data in maps.
* sasl: A socket "registry" has been added making it possible to
list current open sockets.
* kernel: The DNS resolver `inet_res` has been fixed to return
the last intermediate error when subsequent requests times out.
* kernel: The prim_net nif (net/kernel) made use of an undefined
atom, notsup. This has now been corrected.
* kernel: Fix a crash when attempting to log faults when loading
files during early boot.
* kernel: Fix crash in logger when logging to a remote node
during boot.
* kernel: Improved net_kernel debug functionality.
- Changes for 22.2.8:
* diameter: The possibility of choosing a handler process for an
incoming Diameter request with a configured MFA was documented
in OTP 20.0, but counters (with {traffic_counters, true}) were
not incremented when this process was on a remote node.
Counters are now incremented on the node that configures the
transport in question. Introduced in OTP 21.3.
* diameter: Transport options differing from those passed to
diameter:add_transport/2 were used in several situations: when
starting a transport process after connect_timer expiry after
an initial connection attempt has failed, when starting a
transport process after a connection has been accepted, when
sending events, when returning options in
diameter:service_info/2, and possibly more. In particular, the
following configuration options to diameter:add_transport/2
were dropped: avp_dictionaries, incoming_maxlen, spawn_opt,
strict_mbit. Moreover, any service options mistakenly passed to
diameter:add_transport/2 were interpreted as such, instead of
being ignored as the documentation states, with the consequence
that outgoing and incoming requests saw different values of
some options, some were always taken from transport options,
and others from service options. diameter:add_transport/2 must
be called in new code for the fix to have effect. Introduced in
OTP 20.1. - Remove conditions and support for openSUSE/SLE < 15
- Remove not really needed service file _service
- Convert the dependencies to pkgconfig style ones - Changes for 22.2.7:
* compiler: Fixed a bug that could cause the compiler to reject
valid code that used the is_map_key/2 BIF.
* compiler: Fixed a bug that could cause the compiler to reject
valid code that matched the same map key several times.
* compiler: The compiler could crash when compiling a convoluted
receive statement.
* compiler: The compiler could crash when a fun was created but
never used. The compiler could crash when compiling the
expression true = 0 / X.
- jsc#SLE-10913 - Changes for 22.2.6:
* erts: A process could get into an inconsistent state where it
was runnable, but never scheduled for execution. This could
occur when a mix of normal and low priority processes where
scheduled on the same type of dirty scheduler simultaneously. - Changes for 22.2.5:
* erts: A process could end up in a state where it got
endlessly rescheduled without making any progress. This
occurred when a system task, such as check of process
code (part of a code purge), was scheduled on a high
priority process trying to execute on a dirty
scheduler.
* erts: Improved signal handling for processes executing dirty.
For example, avoid busy wait in dirty signal handler
process when process is doing garbage collection on
dirty scheduler.
* stdlib: A directory traversal vulnerability has been eliminated
in erl_tar. erl_tar will now refuse to extract symlinks
that points outside the targeted extraction directory
and will return {error,{Path,unsafe_symlink}}. (Thanks
to Eric Meadows-Jönsson for the bug report and for
suggesting a fix.) - Changes for 22.2.4:
* ssl: Enhance error handling, all ALERTS shall be handled
gracefully and not cause a crash.
* ssl: Enhance alert logging, in some places the role
indication of the alert origin was missing. So the log
would say undefined instead of client or server.
* ssl: Two different optimizations did not work together and
resulted in the possible breakage of connections using
stream ciphers (that is RC4). Reworked the
implementation to avoid this. - Changes for 22.2.3:
* ssl: Fix the handling of GREASE values sent by web browsers
when establishing TLS 1.3 connections. This change improves
handling of GREASE values in various protocol elements sent in
a TLS 1.3 ClientHello.
* ssl: Correct DTLS listen emulation, could cause problems with
opening a new DTLS listen socket for a port previously used by
a now closed DTLS listen socket.
* compiler: Fixed a bug in the compiler that could cause it to
reject valid code. - Changes for 22.2.2:
* erts: Taking a scheduler offline could cause timers set while
executing on that scheduler to be delayed until the scheduler
was put online again. This bug was introduced in ERTS version
10.0 (OTP 21.0).
* erts: The ets:update_counter/4 core dumped when given an
ordered_set with write_concurrency enabled and an invalid
position. This bug has been fixed.
* erts: A process calling erlang:system_flag(multi_scheduling,
block) could end up blocked waiting for the operation to
complete indefinitely.
* erts: Duplicate entries for [socket:]getopt and [socket:]setopt
in man page.
* stdlib: The ets:update_counter/4 core dumped when given an
ordered_set with write_concurrency enabled and an invalid
position. This bug has been fixed.
* crypto: Constant time comparisons added.
* ssh: Fixed that ssh_connection:send could allocate a large
amount of memory if given an iolist() as input data.
* ssh: Safe atom conversions.
* ssh: Constant time comparisons added.
- Changes for 22.2.1:
* erts: Corrected an issue with the new socket api which could
cause a core dump. A race during socket close could cause a
core dump (an invalid nif environment free).
* erts: Corrected an issue with the new socket api which could
cause a core dump. When multiple accept processes waiting for a
connect a connect could cause a core dump.
* snmp: Its now possible to remove selected varbinds (from the
final message) when sending a notification. This is done by
setting the 'value' (in the varbind(s) of the varbinds list) to
'?NOTIFICATION_IGNORE_VB_VALUE'.
* snmp: Its now possible to specify that an oid shall be
"truncated" (trailing ".0" to be removed) when sending an
notification.
* ssl: Add missing alert handling clause for TLS record handling.
Could sometimes cause confusing error behaviors of TLS
connections.
* ssl: Fix handling of ssl:recv that happens during a
renegotiation. Using the passive receive function
ssl:recv/[2,3] during a renegotiation would fail the connection
with unexpected msg. - BuildRequire pkgconfig(libsystemd) instead of systemd-devel:
Allow OBS to shortcut through the -mini flavors. - Changes for 22.2
* http://erlang.org/download/OTP-22.2.README
* Highlights:
* erts: The Kernel application's User's Guide now contains a
Logger Cookbook with common usage patterns.
* erts: Numerous improvements in the new socket and net modules
* Standard libraries: common_test: ct_property_test logging is improved
* Standard libraries: ssl: Correct handling of unordered chains so that it
works as expected
* Tools: Emacs erlang-mode function that lets the user open the documentation
for an Erlang/OTP function in an Emacs buffer has been improved.
Users will be asked if they want the man pages downloaded if they are not present
in the system. - Changes for 22.1.8
* http://erlang.org/download/OTP-22.1.8.README
* erts: Large amounts of quickly executed dirty work could
cause heavy contention on an internal spin lock. The
spin lock was replaced by a mutex which behaves much
better under these conditions. - Changes for 22.1.7
* http://erlang.org/download/OTP-22.1.7.README
* compiler: Fixed a performance bug that caused repeated matches of
large records to take a very long time to compile.
* erts: A literal area could prematurely be released before all
uses of it had been removed. This occurred either when
a terminating process had a complex exit reason
referring to a literal that concurrently was removed,
or when a terminating process continued executing a
dirty NIF accessing a literal (via the heap) that
concurrently was removed.
* erts: Fix bug causing VM crash due to memory corruption of
distribution entry. Probability of crash increases if
Erlang distribution is frequently disconnected and
reestablished towards same node names. Bug exists since
OTP-21.0.
* erts: Fixed bug causing crash of VM built with configuration
- -enable--sharing-preserving. Provoked when a sent
message contains both a bit string and the heap binary
(< 65 bytes) which the bit string was matched from. Bug
exists since OTP-19.0 but has seen to be easier to
provoke since OTP-22.1.
- Changes for 22.1.6
* http://erlang.org/download/OTP-22.1.6.README
* compiler, erts: The compiler could do an unsafe optimization of
receives, which would cause a receive to only scan part
of the message queue.
* crypto: The AEAD tag was not previously checked on decrypt with
chacha20_poly1305
* erts:Fix bug where the receive marker used by the runtime to
do the receive queue optimization could be incorrectly
set. The symptom of this would be that a message that
should match in a receive never matches.
* snmp: Agent discovery cleanup. If there is no receiver of
INFORM then #state.reqs in snmpa_net_if keeps on
growing for DISCOVERY. - Changes for 22.1.5
* http://erlang.org/download/OTP-22.1.5.README
* snmp: Application(s): snmp
Related Id(s): ERIERL-427
The agent discovery process has been made to work with
snmptrapd.. - Changes for 22.1.4
* http://erlang.org/download/OTP-22.1.4.README
* compiler: Fixed a bug where the compiler could generate incorrect
code for a 'receive' statement inside a 'try'.
* crypto: FIxed a bug if the erlang emulator was linked with a
very old cryptolib version (1.0.1 or earlier).
The bug now fixed could have triggered a core dump if
an unknown cipher name was used in crypto functions.
* erts: Erlang/OTP can now be built on macOS Catalina (10.15). - Changes for 22.1.3:
* inets: Add HTTP server error logging vi logger
- Changes for 22.1.2:
* erts: Added the environment variable ERLC_SERVER_ID, which
allows multiple compile servers to run separately under the
same user.
- Changes for 22.1.1:
* erts: A terminating process sending distributed 'EXIT' or
'DOWN' signals while terminating could end up in a state where
no progress at all was made. This was triggered by a
distribution channel that the terminating process was sending
on got busy. This bug has existed since ERTS version 10.4 (OTP
22.0).
* erts: When communicating with a simultaneously exiting port via
the erlang:port_*() BIFs one could sometimes get stray {Ref,
What} messages. Where Ref was a reference and What usually were
the atom badarg.
* snmp: Made it possible to add 'extra socket options' to the
(gen_udp) socket open call (for both manager and agent). A new
option has been added, extra_sock_opts, which makes it possible
for the user to add a list of extra socket options that will be
appended to the other socket options for the open call. See the
snmp application config man page (erl -man 6 snmp) or the
"Configuring the application" chapter of the Users Guide for
more info.
* compiler: Fixed a bug in the bit-syntax optimization pass that
could crash the compiler. - Changes for 22.1:
* kernel: The type specification for gen_sctp:connect/4,5 has
been corrected.
* kernel: Extra -mode flags given to erl are ignored with a
warning.
* kernel: Fix type spec for seq_trace:set_token/2.
* kernel: logger:compare_levels/2 would fail with a badarg
exception if given the values all or none as any of the
parameters. This is now corrected.
* kernel: Fix bug where the log file in logger_std_h would not be
closed when the inode of the file changed. This would in turn
cause a file descriptor leak when tools like logrotate are
used.
* kernel: Fix a race condition in the debugging function
net_kernel:nodes_info/0.
* kernel: Fix race condition when closing a file opened in
compressed or delayed_write mode.
* kernel: The possibility to send ancillary data, in particular
the TOS field, has been added to gen_udp:send/4,5.
* kernel: If the log file was given with relative path, the
standard logger handler (logger_std_h) would store the file
name with relative path. If the current directory of the node
was later changed, a new file would be created relative the new
current directory, potentially failing with an enoent if the
new directory did not exist. This is now corrected and
logger_std_h always stores the log file name as an absolute
path, calculated from the current directory at the time of the
handler startup.
* kernel: Support local sockets with inet:i/0.
* observer: Fix bug after a user followed link on a pid from an
expanded term window.
* observer: Improved dark mode colors on Linux.
* mnesia: mnesia:add_table_copy/3 could cause a deadlock if
called when a new node was starting.
* mnesia: Transactions with sticky locks could with async_asym
transactions be committed in the wrong order, since asym
transaction are spawned on the remote nodes. To fix this bug
the communication protocol between mnesia nodes had to be
updated, thus mnesia will no longer be able to connect to nodes
earlier than mnesia-4.14 , OTP-19.0. *** POTENTIAL
INCOMPATIBILITY ***
* stdlib: re:run() now yields when validating utf8 in a large
subject.
* stdlib: Upgraded the ERTS internal PCRE library from version
8.42 to version 8.43. See
http://pcre.org/original/changelog.txt for information about
changes made to PCRE. This library implements major parts of
the re regular expressions module.
* stdlib: The bug with ID ERL-717 has been fixed. The functions
io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These functions
returned {error,enotsup} before this fix even if stdout and
stdin were connected to a terminal when they were invoked from
an escript or a program started with e.g., erl -noshell.
* stdlib: Fixed handling of ".." and "@" in wildcards. ".." would
only work when preceded by a literal pattern such as in "a/..",
not when preceded by wildcard characters such as in "*/..". The
combination "@/.." was also broken, and in addition "@" in a
pattern could degrade performance of the wildcard matching.
* stdlib: Make sure ets:fun2ms() can handle ++/2 in the head of
functions when called from the shell.
* stdlib: Debugging of time-outs in gen_statem has been improved.
Starting a time-out is now logged in sys:log and sys:trace.
Running time-outs are visible in server crash logs, and with
sys:get_status. Due to this system events {start_timer, Action,
State} and {insert_timout, Event, State} have been added, which
may surprise tools that rely on the format of these events. New
features: The EventContent of a running time-out can be updated
with {TimeoutType, update, NewEventContent}. Running time-outs
can be cancelled with {TimeoutType, cancel} which is more
readable than using Time = infinity. *** POTENTIAL
INCOMPATIBILITY ***
* stdlib: re:run() now avoids validating utf8 in the subject more
than once in the same call. This validation could previously be
performed multiple times when the global option was passed.
* stdlib: ETS ordered_set tables with write_concurrency enabled
has got a performance issue fixed. There were no limits for the
values of internal statistics counters before this fix. This
could result in that the data structure sometimes reacted
slowly to a change in how many parallel processes were using
it.
* stdlib: The ordsets:union/1 is now faster when passed a long
list of ordsets.
* stdlib: unicode:characters_to_binary() could return very small
binaries as reference counted off heap binaries. This could
cause an unnecessary large memory usage and an unnecessary load
on the binary allocator. Small binaries are now always returned
as heap binaries.
* stdlib: Display a more meaningful error message when a bad I/O
server is used in a script written in Erlang (escript).
* stdlib: New feature ets:info(_, binary) to get information
about all reference counted binaries kept by a table. This is
the same kind of debug information that process_info(_, binary)
returns for a process.
* stdlib: Corrected ETS documentation about the behavior of
compiled match specifications when serialized through external
format.
* tools: cover would fail to start if two processes tried to
start it at the exact same time.
* common_test: If a ct hook is installed in the suite/0 function
in a test suite, then the hook's terminate/1 function would be
called several times without it's init/2 function being called
first. This is now corrected.
* common_test: If init_per_testcase fails, the test itself is
skipped. According to the documentation, it should be possible
to change the result to failed in a hook function. The only
available hook function in this case is post_init_per_testcase,
but changing the return value there did not affect the test
case result. This is now corrected.
* common_test: Add ct_netconfc support for NETCONF 1.1 (RFC
6241). The 1.1 base capability can be sent in hello, and RFC
6242 chunk framing is applied when both client and server
advertise 1.1 support.
* common_test: Correct lib_dir paths in common_tests opaque data
structure that is passed to ct_release_test callback modules in
functions upgrade_init/2, upgrade_upgraded/2 and
upgrade_downgraded/2. The incorrect paths may cause confusion
when debugging although it will not cause any incorrect
behavior on the part of common_test as it is currently not
used.
* erts: If you set {linger,{true,0}} on a gen_tcp listen socket,
accept a connection on that socket, and then close the accepted
socket, now the linger zero setting is transferred to the
accepted socket. Before this correction that information was
lost and the close behaviour on the accepted socket incorrect.
* erts: Sending ancillary data implemented in OTP-15747
accidentally left behind test code that caused all UDP sends to
fail on Windows. This has now been fixed.
* erts: In the socket nif, used invalid flags when if-def'ing for
supported TCP flags: TCP_MAXSEG and TCP_NODELAY (the support
function).
* erts: Fixed memory leaks in experimental socket module.
* erts: re:run() now yields when validating utf8 in a large
subject.
* erts: Fixed bug in seq_trace:set_token(label,Term) which could
cause VM crash if Term was heap allocated (not an atom, small
integer, local pid or port). Bug exists since OTP 21.0 when
terms other than small integers were first allowed as labels.
* erts: Extra -mode flags given to erl are ignored with a
warning.
* erts: Don't loop indefinitely when --enable-pgo is given to
configure, but compiler does not support pgo.
* erts: Fix seq_trace:print/2 not to raise badarg exception if
label is not a small integer. Bug exists since OTP 21.0.
* erts: Fixed hipe_flush_icache_range for non-Linux OS on ARM.
* erts: The fix in OTP-15871 was too conservative and disabled
the offending load-time optimization in some cases where it was
safe.
* erts: Upgraded the ERTS internal PCRE library from version 8.42
to version 8.43. See http://pcre.org/original/changelog.txt for
information about changes made to PCRE. This library implements
major parts of the re regular expressions module.
* erts: Fix race condition when closing a socket while using
{active,N} on Windows.
* erts: Allow more than one -config command line option to erl on
Windows to conform with other OS.
* erts: Fix so that ERL_FLAGS environment variable does not
interfere with command line arguments. Before this fix you
could write: ERL_FLAGS="10" erl +S and erlang would start as if
+S had been given the argument 10.
* erts: The bug with ID ERL-717 has been fixed. The functions
io:columns() and io:rows() only worked correctly inside
interactive erlang shells before this fix. These functions
returned {error,enotsup} before this fix even if stdout and
stdin were connected to a terminal when they were invoked from
an escript or a program started with e.g., erl -noshell.
* erts: Do not use named label in ethread.c inline assemble. This
allows erts to be compiled using gcc 9.1.0 with LTO enabled.
* erts: erlang:fun_to_list/1 will now escape the module and
function name when necessary.
* erts: process_info(P,binary) would neglect to look through heap
fragments, potentially missing a few binaries associated with
the process.
* erts: HiPE is now automatically disabled on systems with non-
glibc implementation (for instance musl). This is because musl
does not provide the API's for guaranteeing that signals are
delivered on the correct native stack.
* erts: Fixed bug triggered if a process is killed during call to
persistent_term:put or persistent_term:erase.
* erts: Add units to all memory slogans in the crash dump
documentation.
* erts: Fix a bug in binary_to_term that would crash the emulator
if a term larger than 16GB was to be decoded.
* erts: Fixed bug related to an exiting process sending EXIT and
DOWN signals to remote linked/monitored processes. Bugs exists
since OTP 22.0.
* erts: erlc can now automatically use a compile server to avoid
starting an Erlang system for each file to be compiled in a
multi-file project. See the documentation for how to enable it.
* erts: The possibility to send ancillary data, in particular the
TOS field, has been added to gen_udp:send/4,5.
* erts: The net module has been split into 'net' (kernel) and
prim_net (preloaded).
* erts: Socket counters now works as expected and can also be
extracted with the (new) info function.
* erts: re:run() now avoids validating utf8 in the subject more
than once in the same call. This validation could previously be
performed multiple times when the global option was passed.
* erts: The un-documented function erlang:dist_get_stat/1 now
returns the real value of what the distribution queue contains
instead of a boolean.
* erts: ETS ordered_set tables with write_concurrency enabled has
got a performance issue fixed. There were no limits for the
values of internal statistics counters before this fix. This
could result in that the data structure sometimes reacted
slowly to a change in how many parallel processes were using
it.
* erts: Optimize the reception of large distribution messages.
* erts: Binary matching and functions like split_binary/2 will
now create heap binaries when the results are small enough,
reducing the chances of small sub-binaries keeping large
binaries alive.
* erts: Fixed rare emulator crash in instrument:allocations/0-1.
* erts: Ports could pass very small binaries as reference counted
off heap binaries to processes. This could cause an unnecessary
large memory usage and an unnecessary load on the binary
allocator. Small binaries are now always passed as heap
binaries to processes.
* erts: unicode:characters_to_binary() could return very small
binaries as reference counted off heap binaries. This could
cause an unnecessary large memory usage and an unnecessary load
on the binary allocator. Small binaries are now always returned
as heap binaries.
* erts: Improved erl_nif documentation regarding on_load and
Erlang stub/fallback functions.
* erts: New feature ets:info(_, binary) to get information about
all reference counted binaries kept by a table. This is the
same kind of debug information that process_info(_, binary)
returns for a process.
* erl_docgen: Update the documentation build support to handle
FOP 2.1 .
* ftp: A possibly infinite loop when receiving messages divided
in parts is removed.
* dialyzer: Allow native compilation when using Dialyzer from
Erlang. The options native (defaults to false) and native_cache
have been added.
* eunit: Handle get_until request with explicit encoding in the
implementation of the I/O protocol.
* snmp: Fix various minor issues related to Dialyzer. Mostly
these are dialyzer warnings, but there was also some minor bugs
detected by Dialyzer.
* snmp: Fixed a dets usage problem detected by dialyzer.
* snmp: The function snmp:print_version_info() prints various
version info. For each module a number of items are printed,
such as app vsn and md5 digest. And an attempt was also made to
print "compile time". This used to be available in the
module_info for each module, but has now been removed.
* snmp: The use of the deprecated random module has been replaced
the with rand module.
* snmp: Removed use of the deprecated function
erlang:get_stacktrace(). Instead make use of the 'catch
Class:Error:Stacktrace' feature.
* syntax_tools: Add missing calls to erl_syntax:unwrap/1. The
nodes concerned represent names and values of maps and map
types.
* wx: Fix a driver bug that could crashes when allocating memory.
* erl_interface: Fix bugs in ei_print_term for binaries and bit
strings causing incorrect output.
* erl_interface: Fixed bug in ei_decode_fun for very old fun
encoding format. Bug exist since OTP 22.0.
* erl_interface: ei_print_term() now supports printing of maps
and funs.
* xmerl: xmerl_sax_parser crashed during charset detection when
the xml declarations attribute values was missing the closing
quotation (' or ").
* ssl: Handling of zero size fragments in TLS could cause an
infinite loop. This has now been corrected.
* ssl: DTLS record check needs to consider that a resent hello
message can have a different version than the negotiated.
* ssl: Basic support for TLS 1.3 Client for experimental use. For
more information see the Standards Compliance chapter of the
User's Guide.
* ssl: Correct solution for retaining tcp flow control OTP-15802
(ERL-934) as to not break ssl:recv as reported in (ERL-938)
* ssl: Enhance dialyzer specs to reflect implementation better
and avoid dialyzer warnings for the user that wants to use TLS
with unix domain sockets.
* ssl: Add support for ECDSA signature algorithms in TLS 1.3.
* ssl: Correct error handling of TLS downgrade, possible return
values form ssl:close/2 when downgrading is {ok, Port} or
{error, Reason}, it could happen that only ok was returned
instead of {error, closed} when downgrade failed due to that
the peer closed the TCP connection.
* os_mon: Fix disk_sup to ignore squashfs on Linux when
determining if a mounted filesystem is full or not.
* os_mon: Fix bug where cpu_sup:util() always returned 100% on
systems not using gnu libc, for example Alpine OS.
* ssh: Fixed wrong type definition for the daemon option
subsystems.
* ssh: Fixed a possible SSH logging crash if there was a problem
in an early stage of session setup.
* ssh: The documentation for the modules ssh_connection, ssh_sftp
and ssh_sftpd are now generated from the -spec:s.
* ssh: Internal cleanup including removal of the internal file
ssh_userauth.hrl.
* ssh: Removed unused definitions in ssh.hrl.
* ssh: Removed unused fields in the internal #connection{}
record.
* ssh: To get information of a connection_ref() from for example
ssh:connect/3, there was previously one function available
namely ssh:connection_info/2. This ticket adds
ssh:connection_info/1 which returns all information. For
daemons (servers) started with for example ssh:daemon/2 the
function ssh:daemon_info/1 returning all information was
available. This ticket adds ssh:daemon_info/2 which returns
only the information specified in the second argument. The info
of connections and of daemons now also includes the item
'options'. Only those options that does not have their default
values are returned. For a connection also the items
'algorithms' and 'channels' are added.
* inets: httpd - Accept singel LF as line terminator
* inets: mod_esi will now always propagate the actual HTTP status
code that it answered with, to later mod-modules, and not in
some cases hardcode 200.
* compiler: Code such as the following would crash the compiler
in OTP 22: [some_atom = fun some_function/1]
* compiler: Compilation could get really slow (in the order of
minutes instead of seconds) when compiling huge functions.
(Thanks to Kostis Sagonas for reporting this bug.)
* compiler: Fixed a bug in the validator that could reject valid
code.
* compiler: In rare circumstances, when two clauses had identical
bodies and guard tests that tested a single boolean variable,
the guard test for the second clause could be discarded,
executing the second clause unconditionally if the first clause
was not executed.
* compiler: Fixed extremely slow compilation for huge functions
doing predominantly pattern matching.
* compiler: The compiler could generate unsafe code (that would
crash the runtime system) for map pattern matching. The code
could be unsafe if the matched key was not present in the map
at runtime.
* compiler: Correct code using try/after could fail to compile
when using the option 'no_type_opt'.
* compiler: The compiler could crash when compiling code that
called 'length/1' on a binary extracted using the binary
syntax.
* compiler: Fixed a bug where the compiler could fail with an
internal consistency failure error when compiling receive
statements.
* compiler: Fixed a problem where the compiler would crash when
compiling binary matching in a function head.
* public_key: Support Password based encryption with AES
* public_key: Change dialyzer spec to avoid confusion
* runtime_tools: Fix dbg:stop_clear/0 to also clear trace events
(send and 'receive').
* megaco: Fix various minor issues related to Dialyzer. Mostly
these are dialyzer warnings, but there was also some minor bugs
detected by Dialyzer.
* crypto: The implementation of crypto_one_time/4 is adjusted to
match the type specification. The spec and the black-box
behaviour of the function are unchanged. Some details: Both the
spec and the implementation were correct seen separately. But
with both of them combined simultaneously with
crypto_one_time/5 which was called by the implementation of
crypto_one_time/4, an (obvious) error was detected by a
Dialyzer with more thorough checking than usual.
* crypto: When using crypto with FIPS mode enabled, the digests
were not correctly handled.
* crypto: A memory leak in error handling code in
ng_crypto_init_nif is fixed.
* crypto: Fixed the broken static build of the crypto nifs
* crypto: The Message Authentication Codes (MAC) CMAC, HMAC and
Poly1305 are unified into common functions in the New Crypto
API. See the manual for CRYPTO.
* sasl: The net module has been split into 'net' (kernel) and
prim_net (preloaded).
* jinterface: Replaced deprecated with in
documentation. - Rebased patches:
+ 0001-erts-Do-not-use-named-no_cpuid-label-in-asm.patch dropped (merged upstream) - Udate -ffat-lto-objects in order to properly build static libraries
provided by the package (boo#1142645).
- Use %make_build macro. - Add patch 0001-erts-Do-not-use-named-no_cpuid-label-in-asm.patch:
fix boo#1142913
- Changes for 22.0.7:
* compiler: Fixed a compiler crash introduced in 22.0.6
(OTP-15952).
- Changes for 22.0.6:
* compiler: Fixed an unsafe optimization when matching
tuple_size/1 outside of guards, which could crash the emulator
if the argument was not a tuple.
* compiler: Fixed a rare bug that could cause the wrong kind of
exception to be thrown when a BIF failed in a function that
matched bitstrings.
* compiler: Fixed a bug where receive statements inside try/catch
blocks could return incorrect results.
* ssl: Enhance error handling for erroneous alerts from the peer.
* hipe: The HiPE compiler would badly miscompile certain
try/catch expressions, so it will now refuse to compile modules
containing try or catch. As a consequence of this, dialyzer
will no longer compile key modules to native code. ***
POTENTIAL INCOMPATIBILITY ***

POTENTIAL INCOMPATIBILITY ***
- Changes for 22.0.5:
* inets: Fix a regression in http client that causes a crash when
request URI has no scheme.
* ssl: Fix handling of certificate decoding problems in TLS 1.3
similarly as in TLS 1.2.
* ssl: Hibernation now works as expected in all cases, was
accidently broken by optimization efforts.
* ssl: Fix interoperability problems with openssl when the TLS
1.3 server is configured wirh the option signature_algs_cert.
* dialyzer: Make sure Dialyzer does not crash if the formatting
of results fails. Instead of crashing, an unformatted version
of the results is returned.
* erts: An invalid value test caused the socket:setopt(Socket,
ip, add_membership, ip_mreq()) to fail with badarg. The same
for drop_membership.
* erts: Fixed bug causing VM crash when doing textual dump of a
process containing an unhandled monitor down signal. Textual
process dumps can be done with erlang:system_info(procs), trace
feature process_dump, Erlang shell break menu and a crashdump.
Bug exist since OTP 21.0.
* erts: lists:subtract/2 would produce incorrect results for some
inputs on 64-bit platforms.
* erts: Fixed a bug in the loader that was similar to OTP-15938,
yielding incorrect code for some inputs on 64-bit platforms.
* erts: Fixed bug causing scheduler threads in rare cases to
block spinnning indefinitely. Bug exists since OTP 21.0. - Drop priv/obj directories: boo#1140404 - Version 22.0.4:
* http://erlang.org/download/OTP-22.0.4.README
- Bug Fixes
* erts: Fixed a buffer overflow when binary_to_existing_atom/2
and list_to_existing_atom/2 was used with the latin1
encoding.
* erts: The runtime system disconnected a connection if it
received an exit/2 signal where the recipient was a
process on an old incarnation of the current node. That
is, the receiving node had the same node name, but
another "creation" number. The signal will now just be
dropped since the receiving process no longer exists.
* kernel: user/user_drv could respond to io requests before they
had been processed, which could cause data to be
dropped if the emulator was halted soon after a call to
io:format/2, such as in an escript.
* ssl: Correct handshake handling, might cause strange
symptoms such as ASN.1 certificate decoding issues.
* ssl: Fix handling of the signature_algorithms_cert extension
in the ClientHello handshake message.
* ssl:Handle new ClientHello extensions when handshake is
paused by the {handshake, hello} ssl option. - Version 22.0:
- Potential Incompatibilities:
* gen_* behaviours: If logging of the last N messages through
sys:log/2,3 is active for the server, this log is included in
the terminate report.
* reltool: A new element, Opts, can now be included in a rel
tuple in the reltool release specific configuration format:
{rel, Name, Vsn, RelApps, Opts}.
* All external pids/ports/refs created by erlang:list_to_pid and
similar functions now compare equal to any other pid/port/ref
with same number from that node.
* The old legacy erl_interface library is deprecated as of OTP
22, and will be removed in OTP 23. This does not apply to the
ei library.
* VxWorks is deprecated as of OTP 22 and will be removed in OTP
23.
- New Features:
* Support for Erlang Distribution protocol to split the payload
of large messages into several fragments.
* ETS option write_concurrency now also effects and improves
scalability of ordered_set tables.
* The length/1 BIF used to calculate the length of the list in
one go without yielding, even if the list was very long. Now it
yields when called with long lists.
* A new (still experimental) module socket is introduced. It is
implemented as a NIF and the idea is that it shall be as "close
as possible" to the OS level socket interface.
* Added the NIF function enif_term_type, which helps avoid long
sequences of enif_is_xyz by returning the type of the given
term. This is especially helpful for NIFs that serialize terms,
such as JSON encoders, where it can improve both performance
and readability.
* The compiler has been rewritten to internally use an
intermediate representation based on Static Single Assignment
(SSA). The new intermediate representation makes more
optimizations possible.
* All compiler options that can be given in the source file can
now be given in the option list on the command line for erlc.
* In OTP 22, HiPE (the native code compiler) is not fully
functional. The reasons for this are new BEAM instructions for
binary matching that the HiPE native code compiler does not
support. If erlc is invoked with the +native option, and if any
of the new binary matching instructions are used, the compiler
will issue a warning and produce a BEAM file without native
code.
* Cover now uses the counters module instead of ets for updating
counters. The new function cover:local_only/0 allows running
Cover in a restricted but faster local-only mode. The increase
in speed will vary depending on the type of code being
cover-compiled, as an example the compiler test suite runs more
than twice as fast with the new Cover.
* A simple socket API is provided through the socket module. This
is a low level API that does *not* replace gen_[tcp|udp|sctp].
It is intended to *eventually* replace the inet driver. It also
provides a basic API that facilitates the implementation of
other protocols than TCP, UDP and SCTP. Known issues are; No
support for the Windows OS (currently), a small term leakage.
This feature will be classed as experimental in OTP 22.
* SSL: now uses the new logger API, including log levels and
verbose debug logging.
* SSL: Basic support for TLS 1.3 Server for experimental use.
* crypto: The new hash_info/1 and cipher_info/1 functions returns
maps with information about the hash or cipher in the argument.
- The application otp_mibs has been removed from OTP. - Update to 21.3.8.1:
- Changes for 21.3.8.1:
* http://erlang.org/download/OTP-21.3.8.1.README
* erts: Fixed a buffer overflow when binary_to_existing_atom/2
and list_to_existing_atom/2 was used with the latin1
encoding.
* ssl: Correct solution for retaining tcp flow control
OTP-15802 (ERL-934) as to not break ssl:recv as
reported in (ERL-938)
* tools: cover would fail to start if two processes tried to
start it at the exact same time.
- Update to 21.3.8:
- Changes for 21.3.8:
* http://erlang.org/download/OTP-21.3.8.README
* common_test: The test result when a hook function fails is in
general the same as if the function that the hook is
associated with fails. For example, if
post_init_per_testcase fails the result is that the
test case is skipped, as is the case when
init_per_testcase fails.This, however, was earlier not
true for timetrap timeouts or other error situations
where the process running the hook function was killed.
This is now corrected, so the error handling should be
the same no matter how the hook function fails.
Related Id(s): ERIERL-334
* common_test: In some rare cases, when two common_test nodes used the
same log directory, a timing problem could occur which
caused common_test to crash because it's log cache file
was unexpectedly empty. This is now corrected.
Related Id(s): ERIERL-342
* common_test: Two new common_test hook functions are introduced:
post_groups/2, which is called after Suite:groups/0
post_all/3, which is called after Suite:all/0
A new term, {testcase,TestCase,RepeatProperties} is now
also allowed in the return from all/0. This can be used
for repeating a single test case a specific number of
times, or until it fails or succeeds once.
* eldap, public_key, ssl: Back port of bug fix ERL-893 from OTP-22 and document
enhancements that will solve dialyzer warnings for
users of the ssl application.
This change also affects public_key, eldap (and inet doc).
Related Id(s): ERL-893, ERL-929, PR-2215
* erl_interface: erl_interface/ei refused to use node names with an
alive name (the part of the node name preceding the @
sign) longer than 63 characters and a host name longer
than 64 characters. The total amount of characters
allowed in a node name (alivename@hostname) was thus
limited to 128 characters. These limits applied both to
the own node name as well as node names of other nodes.
Ordinary Erlang nodes limit the node name length to 256
characters, which meant that you could not communicate
with certain Erlang nodes due to their node name used.
erl_interface/ei now allow the total amount of
characters in a node name to be up to 256 characters.
These characters may be distributed between alive name
and host name in whatever way needed. That is, the
maximum amount of characters in the alive name may be
254 and the maximum amount of characters in the host
name may be 254, but in total the node name must not
exceed 256 characters.
* erts: Fixed more bugs in process_info(reductions) causing it
to sometimes behave non-monotonic. That is, a
subsequent call toward the same process could return a
lower reduction value.
Related Id(s): ERIERL-337, OTP-15709
* ssl: Missing check of size of user_data_buffer made internal
socket behave as an active socket instead of active N.
This could cause memory problems.
* eldap, public_key, ssl: Back port of bug fix ERL-893 from OTP-22 and document
enhancements that will solve dialyzer warnings for
users of the ssl application.
This change also affects public_key, eldap (and inet doc).
* stdlib: A bug in gen_statem has been fixed where the internal
timeout message could arrive as an info to the callback
module during high load due to incorrect use of
asynchronous timer cancel. - Update to 21.3.7:
- Changes for 21.3.7:
* http://erlang.org/download/OTP-21.3.7.README
* ssh: When an SSH server receives the very first message on a
new TCP connection, and that message is not the
expected one, the 64 first bytes of the received
message are now dumped in the INFO REPORT that reports
the Protocol Error.
This facilitates the debugging of who sends the bad
message or of detecting a possible port scanning - Update to 21.3.6:
- Changes for 21.3.6:
* http://erlang.org/download/OTP-21.3.6.README
* ssl: With the default BEAST Mitigation strategy for TLS 1.0
an empty TLS fragment could be sent after a one-byte
fragment. This glitch has been fixed. - Update to 21.3.5:
- Changes for 21.3.5:
* http://erlang.org/download/OTP-21.3.5.README
* diameter: Fix inadvertently broad monitor that resulted in
gen_server cast messages to hidden nodes from module
diameter_dist.
* erts: Add missing documentation of new external tags NEW_PID,
NEW_PORT and NEWER_REFERENCE introduced in OTP 19.
These new tags are planned to be "activated" in OTP 23
when distribution capability flag DFLAG_BIG_CREATION
becomes mandatory. Older nodes (>= 19) are able to
decode these new tags and send them back to the new
node. Nodes older than OTP 23 will however never encode
their own local pids, ports and references using the
new tags.
* inets: Fix the internal handling of the option
erl_script_timeout in httpd. If explicit
erl_script_timeout value was supplied in seconds it was
not correctly converted to millisecond units for
internal usage.
This change fixes the handling of erl_script_timeout in
all possible configuration scenarios. - Update to 21.3.4:
- Changes for 21.3.4:
* http://erlang.org/download/OTP-21.3.4.README
* crypto: Fixed build link error on Windows. Unresolved symbol
'bcmp'.
* erl_interface: Fix handling of Makefile dependencies so that parallel
make works properly.
* erts: Fix erlang:open_port/2 with the fd option to correctly
cleanup the pollset when the port is closed. Before
this fix there would be error printouts sent to logger
when the same fd was reused in a new port.
* ssh: The callback ssh_channel:init/1 was missing in OTP-21
* ssh: If a client was connected to an server on an already
open socket, the callback fun(PeerName,FingerPrint) in
the accept_callback option passed the local name in the
argument PeerName instead of the remote name.
* common_test: OTP internal test improvements. - Update to 21.3.3:
- Changes for 21.3.3:
* http://erlang.org/download/OTP-21.3.3.README
* erts: Fixed a bug in seq_trace:reset_trace/0 that could crash
the emulator.
* erts: Fixed bug in process_info(reductions) causing it to
sometimes return invalid results.
* kernel/stdlib: Fixed a performance regression when reading files
opened with the compressed flag. - Update to 21.3.2:
- Changes for 21.3.2:
* http://erlang.org/download/OTP-21.3.2.README
* erts: If a suspend/resume signal pair was sent to a process
while it was executing dirty, the receiving process
could later end up in a suspended state indefinitely.
This bug was introduced in ERTS version 10.0 (OTP
21.0).
* etrs: Fix a possible deadlock when terminating the ERTS
caused by a dirty scheduler not releasing it's
run-queue lock when terminating.
* xmerl: Handling of character references in attributes are
fixed.
* xmerl: Normalization of whitespace characters in attributes
are fixed so it works when character references are
used. - Update to 21.3.1:
- Changes for 21.3.1:
* http://erlang.org/download/OTP-21.3.1.README
* erl_interface: Fixed two bugs in the erl_call program. A missing
initialization (introduced in erl_interface-3.11) which
either caused a crash or failure to connect to or start
a node, and an incorrectly calculated timeout which
could cause failure to start an erlang node. These bugs
only caused failures on some platforms.
* ssl: The timeout for a passive receive was sometimes not
cancelled and later caused a server crash. This bug has
now been corrected.
* ssl: Add tag for passive message (active N) in cb_info to
retain transport transparency.
- Update to 21.3:
- Changes for 21.3:
* http://erlang.org/download/OTP-21.3.README
* Erlang/OTP 21.3 is the third service release for the 21st major release
with improvements, as well as a few features
* Highlights
* Kernel: The standard logger handler, logger_std_h, now has a new internal
feature for log rotation. For full information see the documentation.
* SSL:The Reason part of the error return from the functions connect and
handshake has a better and documented format. This is a potential
incompatibility. See the documentation.
Refactoring of state handling has improved the TLS application data
throughput and reduced CPU overhead
Code optimizations has reduced CPU load for encryption/decryption,
especially for Erlang's distribution protocol over TLS
Now supports active N
* Erl_interface: Support for plugin of a user supplied socket implementation has been added.
* OTP:The HTML reference documentation now shows the OTP version where
modules and functions were first introduced. Versions of OTP older than R13B04 is not shown in the reference
documentation
* For a full list of details see:

- Update to 21.2.7:
- Changes for 21.2.7:
* http://erlang.org/download/OTP-21.2.7.README
* erts, otp: Fixes of install/release phase in build system.
- - The source tree was modified when
installing/releasing and/or applying a patch.
- - Some files were installed with wrong access rights.
- - If applying a patch (using otp_patch_apply) as
another user (except root) than the user that built the
source, the documentation was not properly updated.
* erts, kernel: Setting the recbuf size of an inet socket the buffer is
also automatically increased. Fix a bug where the auto
adjustment of inet buffer size would be triggered even
if an explicit inet buffer size had already been set.
* erts: Reading from UDP using active true or active N mode has
been optimized when more packets than specified by
read_packets are available on the socket.
* erts, kernel: Setting the recbuf size of an inet socket the buffer is
also automatically increased. Fix a bug where the auto
adjustment of inet buffer size would be triggered even
if an explicit inet buffer size had already been set. - Update to 21.2.6:
- Changes for 21.2.6:
* http://erlang.org/download/OTP-21.2.6.README
* erts: When using the {linger,{true,T}} option;
gen_tcp:listen/2 used the full linger time before
returning for example eaddrinuse. This bug has now been
corrected.
* stdlib: Optimize pretty printing of terms. The slower behaviour
was introduced in Erlang/OTP 20. - Drop unsupported openSUSE versions - Update to 21.2.5:
- Changes for 21.2.5:
* http://erlang.org/download/OTP-21.2.5.README
* inets: Fixed bug that causes a crash in http client when using
hostnames (e.g. localhost) with the the option
ipv6_host_with_brackets set to true.
This change also fixes a regression: httpc:request
fails with connection error (nxdomain) if option
ipv6_host_with_brackets set to true and host component
of the URI is an IPv6 address. - update to 21.2.4:
- Changes for 21.2.4:
* http://erlang.org/download/OTP-21.2.4.README
* erts: Fix bug where doing a gen_tcp:send on a socket with
delay_send set to true could cause a segfault if the
other side closes the connection.
Bug was introduced in erts-10.2 (OTP-21.2).
* erts: Fix a race condition when a port program closes that
could result in the next started port to hang during
startup.
Bug was introduced in erts-10.0 (OTP-21.0).
* erts: Fix a bug where polling for external events could be
delayed for a very long time if all active schedulers
were 100% loaded.
Bug was introduced in erts-10.2 (OTP-21.2).
* inets: Make sure ipv6 addresses with brackets in URIs are
converted correctly before passing to lower level
functions like gen_tcp and ssl functions. Could cause
connection to fail.
- update to 21.2.3:
- Changes for 21.2.3:
* http://erlang.org/download/OTP-21.2.3.README
* compiler: An optimization that avoided allocation of a stack
frame for some case expressions was introduced in OTP
21. (ERL-504/OTP-14808) It turns out that in rare
circumstances, this optimization is not safe.
Therefore, this optimization has been disabled.
* erts: Fixed a crash when dangling files were closed after
init:restart/0.
* erts: A bug that could cause dirty schedulers to become
unresponsive has been fixed.
* ssl: Fix encoding of the SRP extension length field in ssl.
The old encoding of the SRP extension length could
cause interoperability problems with third party SSL
implementations when SRP was used.
* ssl: Guarantee active once data delivery, handling TCP
stream properly.
Correct gen_statem returns for some error cases
* xmerl: The charset detection parsing crash in some cases when
the XML directive is not syntactic correct. - update to 21.2.2:
- Changes for 21.2.2:
* http://erlang.org/download/OTP-21.2.2.README
* ssh: Fixed port leakage if a ssh:daemon call failed.
- update to 21.2.1:
- Changes for 21.2.1:
* http://erlang.org/download/OTP-21.2.1.README
* erts: Fixed bug on big endian architectures when changing
file permissions or ownership with file:change_mode,
change_owner, change_group or write_file_info. Bug
exists since OTP-21.0.
* erts: Fixed bug in operator band of two negative operands
causing erroneous result if the absolute value of one
of the operands have the lowest N*W bits as zero and
the other absolute value is not larger than N*W bits. N
is an integer of 1 or larger and W is 32 or 64
depending on word size.
* ssl: Fixed renegotiation bug. Client did not handle server
initiated renegotiation correctly after rewrite to two
connection processes, due to ERL-622 commit
d87ac1c55188f5ba5cdf72384125d94d42118c18. This could
manifest it self as a " bad_record_mac" alert.
Also included are some optimizations
- update to 21.2:
- Changes for 21.2:
* http://erlang.org/download/OTP-21.2.README
* HIGHLIGHTS
* erts, sasl: New counters and atomics modules supplies access to
highly efficient operations on mutable fixed word sized
variables.
* erts: There is a new module persistent_term that implements a
term storage suitable for terms that are frequently
used but never or infrequently updated. Lookups are
done in constant time without copying the terms.
* ssh: Requires OpenSSL 1.1.1 or higher as cryptolib under the
OTP application crypto.
* ssl: *** POTENTIAL INCOMPATIBILITY ***
ssl now uses active n internally to boost performance.
Old active once behavior can be restored by setting
application variable see manual page for ssl
application (man 6).
* erts: Add a new pollset that is made to handle sockets that
use {active, true} or {active, N}. The new pollset will
not be polled by a pollthread, but instead polled by a
normal scheduler.
This change was made because of the overhead associated
with constantly having to re-apply the ONESHOT
mechanism on fds that all input events were
interesting.
The new pollset is only active on platforms that
support concurrent kernel poll updates, i.e. Linux and
BSD.
* POTENTIAL INCOMPATIBILITIES:
kernel: A new function, logger:update_handler_config/3 is
added, and the handler callback changing_config now has
a new argument, SetOrUpdate, which indicates if the
configuration change comes from set_handler_config/2,3
or update_handler_config/2,3.
This allows the handler to consistently merge the new
configuration with the old (if the change comes from
update_handler_config/2,3) or with the default (if the
change comes from set_handler_config/2,3).
The built-in handlers logger_std_h and
logger_disk_log_h are updated accordingly. A bug which
could cause inconsistency between the handlers'
internal state and the stored configuration is also
corrected.
* ssl: ssl now uses active n internally to boost performance.
Old active once behavior can be restored by setting
application variable see manual page for ssl
application (man 6).

* erts: Added an optional ./configure flag to compile the
emulator with spectre mitigation:
- -with-spectre-mitigation
Note that this requires a recent version of GCC with
support for spectre mitigation and the
- -mindirect-branch=thunk flag, such as 8.1. - Pack /etc/init.d/epmd only for systemd-less cases (boo#1116009) - update to 21.1.2:

* compiler: Fixed a bug where incorrect code was generated
following a binary match guard.
* erts: Fixed a rare bug where files could be closed on a
normal instead of an IO scheduler, resulting in system
instability if the operation blocked.
* public_key: Add DSA SHA2 oids in public_keys ASN1-spec and
public_key:pkix_sign_types/1 - Fix instructions for changing address for epmd.socket service. The
ListenStream option needs to be completely overriden otherwise the
socket will be started with multiple ListenStream options and it
will fail. - update to 21.1.1:
- Changes for 21.1.1:
- http://erlang.org/download/OTP-21.1.1.README
* erts: Fixed a memory leak on errors when reading files.
* ssl: From ssl-9.0.2. CLOSE ALERTS could under some
circumstances be encoded using an incorrect cipher
state. This would cause the peer to regard them as
unknown messages.
* ssl: Correct handling of socket packet option with new TLS
sender process, from ssl-9.0.2. When changing the
socket option {packet, 1|2|3|4} with ssl:setopts/2 the
option must internally be propagated to the sender
process as well as the reader process as this
particular option also affects the data to be sent.
* eldap: A race condition at close could cause the eldap client
to exit with a badarg message as cause.
- Changes for 21.1:
- http://erlang.org/download/OTP-21.1.README
* ssh: The key exchange methods
'curve25519-sha256@libssh.org', 'curve25519-sha256' and
'curve448-sha512' are implemented. The last two are
defined in
https://tools.ietf.org/html/draft-ietf-curdle-ssh-curves
They all depends on that OpenSSL 1.1.1 or higher is
used as cryptolib.
* crypto: The typing in the CRYPTO and PUBLIC_KEY applications
are reworked and a few mistakes are corrected.
The documentation is now generated from the typing and
some clarifications are made.
A new chapter on Algorithm Details such as key sizes
and availability is added to the CRYPTO User's Guide.
* erts: The socket options recvtos, recvttl, recvtclass and
pktoptions have been implemented in the socket modules.
See the documentation for the gen_tcp, gen_udp and inet
modules. Note that support for these in the runtime
system is platform dependent. Especially for pktoptions
which is very Linux specific and obsoleted by the RFCs
that defined it.
* ssh: The cipher 'chacha20-poly1305@openssh.com' is now
supported if OpenSSL 1.1.1 or higher is used as
cryptolib.
- Changes for 21.0.9:
- http://erlang.org/download/OTP-21.0.9.README
* compiler: Fix a regression in OTP-15204 that removed .beam file
metadata that some external build tools relied on.
* erts: As of ERTS version 10.0 (OTP 21.0) the erl_child_setup
program, which creates port programs, ignores TERM
signals. This setting was unintentionally inherited by
port programs. Handling of TERM signals in port
programs has now been restored to the default behavior.
That is, terminate the process.
* erts: The fix made for OTP-15279 in erts-10.07 (OTP-21.0.8)
was not complete. It could cause a new connection
attempt to be incorrectly aborted in certain cases.
This fix will amend that flaw.
- Changes for 21.0.8:
- http://erlang.org/download/OTP-21.0.8.
* erts: A process could get stuck in an infinite rescheduling
loop between normal and dirty schedulers. This bug was
introduced in ERTS version 10.0.
* erts: Garbage collection of a distribution entry could cause
an emulator crash if net_kernel had not brought
previous connection attempts on it down properly.
* kernel: Fixed bug in net_kernel that could cause an emulator
crash if certain connection attempts failed. Bug exists
since kernel-6.0 (OTP-21.0).
- Changes for 21.0.7:
- http://erlang.org/download/OTP-21.0.7.
* erts: A race between termination of a process and resume of
the same process via erlang:resume_process/1 could
cause the VM to crash. This bug was introduced in erts
version 10.0 (OTP 21.0).
* erts: When tracing on running, in trace events could be lost
when a process was rescheduled between a dirty and a
normal scheduler.
- Changes for 21.0.6:
- http://erlang.org/download/OTP-21.0.6.README
* crypto: Update the crypto engine functions to handle multiple
loads of an engine.
* inets: Change status code for no mod found to handle request
to 501
* ssl: Correct cipher suite handling for ECDHE_*, the
incorrect handling could cause an incorrrect suite to
be selected and most likly fail the handshake.
- Changes for 21.0.5:
- http://erlang.org/download/OTP-21.0.5.README
* POTENTIAL INCOMPATIBILITIES erts:
Fixed a bug causing some Erlang references to be
inconsistently ordered. This could for example cause
failure to look up certain elements with references as
keys in search data structures. This bug was introduced
in R13B02.
* compiler: Fixed an issue where files compiled with the
+deterministic option differed if they were compiled in
a different directory but were otherwise identical.
* crypto: Fixed a node crash in crypto:compute_key(ecdh, ...)
when passing a wrongly typed Others argument.
* erts: Fixed a bug which caused an emulator crash when
enif_send() was called by a NIF that executed on a
dirty scheduler. The bug was either triggered when the
NIF called enif_send() without a message environment,
or when the process executing the NIF was send traced.
- Changes for 21.0.4:
- http://erlang.org/download/OTP-21.0.4.README
* erts: Fixed a crash when matching directly against a literal
map using a single key that had been saved on the
stack.
* erts: Fix node crash when passing a bad time option to
file:read_file_info/2.
- Changes for 21.0.3:
- http://erlang.org/download/OTP-21.0.3.README
* otp: Build support for the erlang/corba repository.
* erts: Fixed a scheduler bug that caused normal schedulers to
run dirty code.
* erts: Fixed a bug in erlang:trace_info/2 which caused the
emulator to crash when a bad argument was passed. The
bug was introduced in ERTS version 10.0.
- Changes for 21.0.2:
- http://erlang.org/download/OTP-21.0.2.README
* compiler: In rare cases involving matching of binary literal
strings, the compiler could optimize away code that
should be executed.
* compiler:There could be an internal consistency check failure
when compiling code that called map_get(Key, Map) and
then updated the same map.
* compiler: In rare circumstances, the compiler could crash in
beam_jump when compiling a floating point operation.
* erts: Fixed a rare bug that could cause processes to be
scheduled after they had been freed
* erts: Fixed a race condition in the inet driver that could
cause receive to hang when the emulator was compiled
with gcc 8.
* public_key: Fix some of the keylengths in the newly generated moduli
file in public_key are not universally supported. This
could cause the SSH key exchange
diffie-hellman-group-exchange-sha* to fail.
Those keylengths are now removed.
* stdlib: Fix a bug that could cause a crash when formatting a
list of non-characters using the control sequences p or
P and limiting the output with the option chars_limit.
- Changes for 21.0.1:
- http://erlang.org/download/OTP-21.0.1.
* compiler:The compiler could crash when compiling a
complicated function that used the binary syntax.
- Changes for 21.0:
- http://erlang.org/download/otp_src_21.0.readme
* Erlang/OTP 21 is a new major release with new features, improvements as well as incompatibilities.
* Potential Incompatibilities:
- All Corba applications are now moved from the OTP repository
- A new Corba repository will be created https://github.com/erlang
- New applications ftp and tftp, moved from inets
- ssl no longer supports 3_DES cipher suites or RSA-key exchange cipher suites by default
- Erlang:monitor on a primitive node (erl_interface, jinterface, etc) will no longer fail with badarg exception.
Instead a monitor will be created, but it will only supervise the connection to the node.
* Highlights:
* Erts:
- Enhanced IO scalability
- Support for usage of distribution controller processes for alternative transports, routing etc
- compact instructions on 64bit systems for code below 4GB 20% less memory for loaded code
- Rewrite of the efile-driver with NIFs and "Dirty schedulers" resulting in faster file operations
non-smp VM removed
- link and monitor optimized for scalability - update to 20.3.8.9:
- Changes for 20.3.8.9:
- http://erlang.org/download/OTP-20.3.8.9.README
* Fix a regression in OTP-15204 that removed .beam file metadata
- Changes for 20.3.8.8:
- http://erlang.org/download/OTP-20.3.8.8.README
* inets: Do not use chunked-encoding with 1xx, 204 and 304
responses when using mod_esi
* inets: Add robust handling of chunked-encoded HTTP responses
with an empty body (1xx, 204, 304)
- Changes for 20.3.8.7:
- http://erlang.org/download/OTP-20.3.8.7.README
* crypto: Update the crypto engine functions to handle multiple
loads of an engine
* mnesia: Fixed a bug where the bag table index data was not
deleted when objects were deleted. - Update to 20.3.8.6:
* inets: Change status code for no mod found to handle request
to 501 - Update to 20.3.8.5.
- Changes for 20.3.8.5:
* erts: Fixed a bug causing some Erlang references to be
inconsistently ordered. This could for example cause failure
to look up certain elements with references as keys in search
data structures. This bug was introduced in R13B02. Thanks to
Simon Cornish for finding the bug and supplying a fix.
* compiler: Fixed an issue where files compiled with the
+deterministic option differed if they were compiled in a
different directory but were otherwise identical.
* crypto: Fixed a node crash in crypto:compute_key(ecdh, ...)
when passing a wrongly typed Others argument.
* erts: Fixed a bug which caused an emulator crash when
enif_send() was called by a NIF that executed on a dirty
scheduler. The bug was either triggered when the NIF called
enif_send() without a message environment, or when the process
executing the NIF was send traced.
* erts: Fixed a bug causing some Erlang references to be
inconsistently ordered. This could for example cause failure
to look up certain elements with references as keys in search
data structures. This bug was introduced in R13B02. Thanks to
Simon Cornish for finding the bug and supplying a fix.
* mnesia: When master node is set do not force a load from
ram_copies replica when there are no available disc_copies,
since that would load an empty table. Wait until a disk
replica is available or until user explicitly force_loads the
table.
* mnesia: Allow to add replicas even if all other replicas are
down when the other replicase are not stored on disk.
* ssl: Correct handling of empty server SNI extension
* ssl: Correct cipher suite handling for ECDHE_*, the incorrect
handling could cause an incorrrect suite to be selected and
most likly fail the handshake.
- Changes for 20.3.8.4:
* asn1: A bug in ASN.1 BER decoding has been fixed. When
decoding a recursively enclosed term the length was not
propagated to that term decoding, so if the length of the
enclosed term was longer than the enclosing that error was not
dectected. A hard coded C stack limitation for decoding
recursive ASN.1 terms has been introduced. This is currently
set to 8 kWords giving a nesting depth of about 1000 levels.
Deeper terms can not be decoded, which should not be much of a
real world limitation.
- Changes for 20.3.8.3:
* erts: Fixed a race condition in the inet driver that could
cause receive to hang when the emulator was compiled with gcc8.
* erts: Fix bug in generation of erl_crash.dump, which could
cause VM to crash. Bug exist since erts-9.2 (OTP-20.2).
* ic: Fixed potential buffer overflow bugs in
oe_ei_encode_long/ulong/longlong/ulonglong functions on 64-bit
architectures. These functions expect 32 bit integers as the
IDL type "long" is defined as 32 bits. But there is nothing
preventing user code from "breaking" the interface and pass
larger values on 64-bit architectures where the C type "long"
is 64 bits.
* inets: Enhance error handling, that is mod_get will return 403
if a path is a directory and not a file.
* kernel: Non semantic change in dist_util.erl to silence
dialyzer warning.
* ssl: Improve cipher suite handling correcting ECC and TLS-1.2
requierments. Backport of solution for ERL-641
* ssl: Option keyfile defaults to certfile and should be trumped
with key. This failed for engine keys.
- Changes for 20.3.8.2:
* erl_interface: Make ei_connect and friends also accept state
ok_simultaneous during handshake, which means the other node
has initiated a connection setup that will be cancelled in
favor of this connection.
* erts: Fixed a rare bug that could cause processes to be
scheduled after they had been freed.
* ic: Fixed bug in ic causing potential buffer overrun in
funtion oe_ei_encode_atom. Bug exists since ic-4.4.4
(OTP-20.3.4).
* kernel: Fix some potential buggy behavior in how ticks are
sent on inter node distribution connections. Tick is now sent
to c-node even if there are unsent buffered data, as c-nodes
need ticks in order to send reply ticks. The amount of sent
data was also calculated wrongly when ticks were suppressed
due to unsent buffered data.
- Changes for 20.3.8.1:
* inets: Options added for setting low-level properties on the
underlying TCP connections. The options are: sock_ctrl,
sock_data_act and sock_data_pass. See the manual for details.
* ssh: SFTP clients reported the error reason "" if a non-OTP
sftp server was killed during a long file transmission. Now
the signal name (for example "KILL") will be the error reason
if the server's reason is empty. The documentation also lacked
type information about this class of errors.
* ssh: Fix ssh_sftp decode error for sftp protocol version 4
* syntax_tools: Fix a bug regarding reverting map types.
- Changes for 20.3.8:
* erts: Fixed bug in ets that could cause VM crash if process A
terminates after fixating a table and process B deletes the
table at "the same time". The table fixation could be done
with ets:safe_fixtable or if process A terminates in the
middle of a long running select or match call.
* snmp: The Snmp MIB compiler now allows using a
TEXTUAL-CONVENTION type before defining it.
- Changes for 20.3.7:
* erl_docgen: Update makefile so db_funcs.xsl is a part of the
installed application.
* erts: Fixed bug in enif_binary_to_term which could cause
memory corruption for immediate terms (atoms, small integers,
pids, ports, empty lists).
* erts: Fixed bug in erlang:system_profile/2 that could cause
superfluous {profile,_,active,_,_} messages for terminating
processes.
* inets: The option max_headers operated on the individual
header length instead of the total length of all headers. Also
headers with empty keys are now discarded.
- Changes for 20.3.6:
* crypto: If OPENSSL_NO_EC was set, the compilation of the
crypto nifs failed.
* crypto: C-compile errors for LibreSSL 2.7.0 - 2.7.2 fixed
* ssh: Host key hash erroneously calculated for clients
following draft-00 of RFC 4419, for example PuTTY
* ssh: Renegotiation could fail in some states
- Changes for 20.3.5:
* erts: Fixed a crash in heart:get_cmd/0 when the stored command
was too long.
* ssl: Proper handling of clients that choose to send an empty
answer to a certificate request.
- Changes for 20.3.4:
* erl_interface: Fix bug in ei_connect functions that may cause
failure due to insufficient buffer space for gethostbyname_r.
* erl_interface, ic: Optimize encoding/decoding for pure 7-bit
ascii atoms.
* inets: Fix broken options handling in httpc (ERL-441).
* ssh: An ssh_sftp server (running version 6) could fail if it
is told to remove a file which in fact is a directory.
* ssh: Fix rare spurios shutdowns of ssh servers when receiveing
{'EXIT',_,normal} messages.
- Changes for 20.3.3:
* sasl: When upgrading with instruction 'restart_new_emulator',
the generated temporary boot file used 'kernelProcess'
statements from the old release instead of the new release.
This is now corrected. - Update to 20.3.2
* ssl: Added new API functions to facilitate cipher suite handling
* erts, observer: More crash dump info such as: process binary
virtual heap stats, full info for process causing out-of-mem
during GC, more port related info, and dirty scheduler info.
* inets: Add support for unix domain sockets in the http client. - Update to 20.2.2.
- Changes for 20.2.2:
* mnesia: Removed a quadratic behavior in startup. This change
implies that backend plugins (if used) must be set when the
schema is created or via configuration parameters before mnesia
is started.
* mnesia: Bad timing could crash mnesia after a checkpoint was
deactivated and reactivated with the same checkpoint name on
different tables.
- Changes for 20.2.1:
* ssh: Fix problem with OpenSSH 7.2 (and later) clients that has
used sha1 instead of sha2 for rsa-sha-256/512 user's public
keys.
- Highlighted changes for 20.2:
* crypto, ssl: The crypto API is extended to use private/public
keys stored in an Engine for sign/verify or encrypt/decrypt
operations. The ssl application provides an API to use this new
engine concept in TLS.
* ssh: SSH can now fetch the host key from the private keys stored
in an Engine. See the crypto application for details about
Engines.
* ssl: A new command line option -ssl_dist_optfile has been added
to facilitate specifying the many options needed when using SSL
as the distribution protocol.
* stdlib: Improve performance of the new string functionality when
handling ASCII characters. - Update to 20.1.5:
* erts: Fixed a regression in zlib:gunzip/1 that prevented it
from working when the decompressed size was a perfect multiple
of 16384. This regression was introduced in 20.1.1
* erts: Fixed a memory corruption bug in enif_inspect_iovec;
writable binaries stayed writable after entering the iovec.
* erts: Fixed a crash in enif_inspect_iovec on encountering empty
binaries.
* erts: zlib:deflateParams/3 will no longer return buf_error when
called after zlib:deflate/2 with zlib 1.2.11.
* inets: Correct the handling of location headers so that the
status code is not hard coded. This should have been fixed by
commit 2cc5ba70cbbc6b3ace81a2a0324417c3b65265bb but
unfortunately was broken during a code refactoring and
unnoticed due to a faulty placed test case.
- Update to 20.1.4:
* inets: Fix broken handling of POST requests
* inets: Make sure ints:stop/2 of the service httpd is
synchronous
* inets: Honor status code returned by ESI script and modernize
"location" header handling.
- Update to 20.1.3:
* diameter: A fault introduced in diameter 2.1 could cause decode
errors to be ignored in AVPs following the header of aGrouped
AVP.
* erts: Added zlib:set_controlling_process/2 to move a zstream()
between processes.
* erts: Fix so that schedulers are bound correctly when the first
available cpu is not the first detected cpu. e.g. when using
"taskset -c X..Y" when X is not equal to 0.
* snmp: The recbuf configuration option was not propagated
correctly to the socket for the SNMP Manager. - Replace references to /var/adm/fillup-templates with new
%_fillupdir macro (boo#1069468) - Update to 21.1.2:
* diameter: An inadvertently removed monitor in diameter 2.1
caused the ets table diameter_reg to leak entries, and caused
service restart and more to fail.
* erts: Fixed bug that could cause a VM crash when a corrupt
message is received on distribution channel from other node.
- Update to 20.1.1:
* compiler: The compiler could issue an incorrect internal
consistency failure diagnostic for some complicated bit syntax
maches.
* erts: The new zlib module returned a data_error when inflating
concatenated streams, which was incompatible with the old
module's behavior of returning the uncompressed data up to the
end of the first stream.
* erts: zlib:gunzip/1 will no longer stop at the end of the first
stream when decompressing concatenated gzip files.
* ssh: Fixed broken printout
* ssh: Disable aes_gcm ciphers if peer is OpenSSH 6.2 which is
known to have trouble with them in some cases.
- Update to 20.1:
* crypto, public_key: Extend crypto and public_key functions
sign and verify with: support for RSASSA-PS padding for
signatures and for saltlength setting X9.31 RSA padding. sha,
sha224, sha256, sha384, and sha512 for dss signatures as
mentioned in NIST SP 800-57 Part 1. ripemd160 to be used for
rsa signatures. A new tuple in crypto:supports/0 reports
supported MAC algorithms.
* diameter: Add service option decode_format to allow incoming
messages to be decoded into maps instead of records. Decode
performance has been improved. Add service/transport option
avp_dictionaries to give better support for dictionaries only
defining AVPs.
* erts: Upgraded the ERTS internal PCRE library from version
8.40 to version 8.41.
* erts, kernel, tools: Profiling with lock counting can now be
fully toggled at runtime in the lock counting emulator
(-emu_type lcnt). Everything is enabled by default to match
the old behavior, but specific categories can be toggled at
will with minimal runtime overhead when disabled. Refer to the
documentation on lcnt:rt_mask/1 for details.
* lcnt:collect and lcnt:clear will no longer block all other
threads in the runtime system. This makes it possible to run
the lock counting under heavier load.
* erts: The zlib module has been refactored and all its
operations will now yield appropriately, allowing them to be
used freely in concurrent applications.
* erts, tools: Add erlang:iolist_to_iovec/1, which converts an
iolist() to an erlang:iovec(), which is suitable for use with
enif_inspect_iovec().
* erts: Add new nif API functions for managing an I/O Queue. The
added functions are: enif_ioq_create(), enif_ioq_destroy(),
enif_ioq_enq_binary(), enif_ioq_enqv(), enif_ioq_deq(),
enif_ioq_peek(), enif_inspect_iovec(), enif_free_iovec()
* observer/crashdump_viewer: Reading of crash dumps with many
binaries is optimized. A progress bar is shown when the detail
view for a process is opened. The cdv script now sets
ERL_CRASH_DUMP_SECONDS=0 to avoid generating a new crash dump
from the node running the Crashdump Viewer.
* observer: Add system statistics and limits to frontpage in
observer.
* public_key, ssl**: Improved error propagation and reports
* ssh: A new option modify_algorithms is implemented. It enables
specifying changes on the default algorithms list. See the
reference manual and the SSH User's Guide chapter "Configuring
algorithms in SSH".
* tools/xref: The predefined Xref analysis locals_not_used now
understands the -on_load() attribute and does not report
unused functions.
* tools/fprof: When sampling multiple processes and analyzing
with totals set to true, the output now sums together all
caller and callee entries which concerns the same function.
Previous behaviour was to report each contributing entry
separately. - Only Java 1.6 is supported by Erlang since 18.0 release - Update to 20.0.5:
* erts: Fixed bug in binary_to_term and binary_to_atom that could
cause VM crash. Typically happens when the last character of an
UTF8 string is in the range 128 to 255, but truncated to only
one byte. Bug exists in binary_to_term since ERTS version
5.10.2 (OTP_R16B01) and binary_to_atom since ERTS version 9.0
(OTP-20.0).
* inets: http_uri aligned to follow RFC 3986 and not convert "+"
to space when decoding URIs.
* inets: Added new option max_client_body_chunk to httpd server
to allow chunked delivery of PUT and POST data to mod_esi
callback. Note, new mod_esi callback implementation is
required. Also correct value provided by server_name
environment variable. - Update to 20.0.4:
* dializer: Fix a bug where merging PLT:s could lose info. The
bug was introduced in Erlang/OTP 20.0.
* erts: A timer internal bit-field used for storing scheduler id
was too small. As a result, VM internal timer data structures
could become inconsistent when using 1024 schedulers on the
system. Note that systems with less than 1024 schedulers are
not effected by this bug. This bug was introduced in ERTS
version 7.0 (OTP 18.0).
* erts: Automatic cleanup of a BIF timer, when the owner process
terminated, could race with the timeout of the timer. This
could cause the VM internal data structures to become
inconsistent which very likely caused a VM crash. This bug was
introduced in ERTS version 9.0 (OTP 20.0).
- Update to 20.0.3:
* asn1: Default values now work in extension for PER, so if you
give the atom asn1_DEFAULT instead of a value it will become
the default value.
* compiler: Fail labels on guard BIFs weren't taken into account
during an optimization pass, and a bug in the validation pass
sometimes prevented this from being noticed when a fault
occurred.
* erts: Binary append operations did not check for overflow,
resulting in nonsensical results when huge binaries were
appended.
* ssh: All unknown options are sent to the transport handler
regardless of type. - Update to 20.0.2:
* asn: Fixed compilation error of generated code caused by a
missing quotation of function names as part of an external call for
encoding.
* erts: Added missing release notes for OTP-14491 ("performance
bug in pre-allocators") which was included in erts-9.0.1 (OTP-20.0.1).
* erts: Fixed a bug that prevented TCP sockets from being
closed properly on send timeouts.
* erts: Fixed bug in operator bxor causing erroneuos result
when one operand is a big *negative* integer with the lowest N*W bits as
zero and the other operand not larger than N*W bits. N is an integer of 1
or larger and W is 32 or 64 depending on word size.
* kernel: The documentation for the 'quiet' option in
disk_log:open/1 had an incorrect default value. - erlang-gs application has been depricated - Update to 20.0.1:
* erts: Fixed a bug in gen_tcp:send where it never returned when
repeatedly called on a remotely closed TCP socket.
* erts: Fixed segfault that could happen during cleanup of aborted
erlang:port_command/3 calls. A port_command is aborted if the
port is closed at the same time as the port_command was issued.
This bug was introduced in erts-8.0.
* erts: Fixed implementation of statistics(wall_clock) and
statistics(runtime) so that values do not unnecessarily wrap due
to the emulator. Note that the values returned by
statistics(runtime) may still wrap due to limitations in the
underlying functionality provided by the operating system.
* erts: Fix performance bug in pre-allocators that could cause
them to permanently fall back on normal more expensive memory
allocation. Pre-allocators are used for quick allocation of
short lived meta data used by messages and other scheduled
tasks. Bug exists since OTP_R15B02.
* runtime_tools: A faulty encoding comment was added when saving
trace patterns to file. This is now corrected.
* stdlib: A bug in proc_lib:format() introduced in Erlang/OTP 20.0
is corrected.
* stdlib: Fix string:len/1 to be compatible with previous
versions.
* stdlib: In OTP-20.0, the behavior of c, make, and ct_make was
changed so that in some cases the beam files by default would be
written to the directory where the source files were found. This
is now changed back to the old behavior so beam files are by
default written to current directory.
- Update to 20.0.0:
* Potential Incompatibilities
* ERTS:
* The non SMP Erlang VM is deprecated and not built by default
* Remove deprecated erlang:hash/2
* erlang:statistics/1 with scheduler_wall_time now also
includes info about dirty CPU schedulers.
* The new purge strategy introduced in OTP 19.1 is mandatory
and slightly incompatible for processes holding funs
* see erlang:check_process_code/3.
* The NIF library reload is not supported anymore.
* Atoms can now contain arbitrary unicode characters which
means that the DFLAG_UTF8_ATOMS capability in the
distribution protocol must be supported if an OTP 20 node
should accept the connection with another node or library.
Third party libraries which uses the distribution protocol
need to be updated with this.
* Asn1: Deprecated module and functions removed (asn1rt,
asn1ct:encode/3 and decode/3)
* Ssh: client only option in a call to start a daemon will now fail
* Highlights
* Erts:
* Dirty schedulers enabled and supported on VM with SMP support.
* support for “dirty” BIFs and “dirty” GC.
* erlang:garbage_collect/2 for control of minor or major GC
* Erlang literals are no longer copied when sending messages.
* Improved performance for large ETS tables, >256 entries
(except ordered_set)
* erlang:system_info/1 atom_count and atom_limit
* Reduced memory pressure by converting sub-binaries to
heap-binaries during GC
* enif_select, map an external event to message
* Improvements of timers internally in the VM resulting in
reduced memory consumption and more efficient administration
for timers
* Compiler:
* Code generation for complicated guards is improved.
* Warnings for repeated identical map keys. #{'a'=>1, 'b'=>2,
'a'=>3} will warn for the repeated key a.
* By default there is now a warning when export_all is used.
Can be disabled
* Pattern matching for maps is optimized
* New option deterministic to omit path to source + options
info the BEAM file.
* Atoms may now contain arbitrary unicode characters.
* compile:file/2 has an option to include extra chunks in the
BEAM file.
* Misc other applications:
* Significantly updated string module with unicode support and
many new functions
* crypto now supports OpenSSL 1.1
* Unnamed ets tables optimized
* gen_fsm is deprecated and replaced by gen_statem
* A new event manager to handle a subset of OS signals in
Erlang
* Optimized sets add_element, del_element and union
* Added rand:jump/0-1
* When a gen_server crashes, the stacktrace for the client
will be printed to facilitate debugging.
* take/2 has been added to dict, orddict, and gb_trees.
* take_any/2 has been added to gb_trees
* erl_tar support for long path names and new file formats
* asn1: the new maps option changes the representation of
SEQUENCE to be maps instead of records
* A TLS client will by default call
public_key:pkix_verify_hostname/2 to verify the hostname
* ssl: DTLS documented in the API, experimental
* ssh: improving security, removing and adding algorithms
* New math:fmod/2 - Disable global PIE for erlang, code is currently not fully
ready. - Update to 19.3.2:
* erts: The +Bi command line argument of erl erroneously caused
SIGTERM to be ignored by the VM as well as of all its child
processes. This bug was introduced in erts version 8.3. - Update to 19.3.1:
* crypto: Fix a bug with AES CFB 128 for 192 and 256 bit keys.
Thanks to kellymclaughlin !
* erts: Trying to open a directory with file:read_file/1 on Unix
leaked a file descriptor. This bug has now been fixed.
* erts: Invoking init:stop/0 via the SIGTERM signal, in a non-SMP
BEAM, could cause BEAM to terminate with fatal error. This has
now been fixed and the BEAM will terminate normally when SIGTERM
is received.
* inets: Fixed a bug in ftp that made further operations after a
recv_chunk operation impossible.
* ssh: ssh:daemon_info/1 crashed if the listening IP was not 'any'
* ssl: Correct active once emulation, for TLS. Now all data
received by the connection process will be delivered through
active once, even when the active once arrives after that the
gen_tcp socket is closed by the peer. - Changes since 19.2:
* crypto, ssh: The implementation of the key exchange algorithms
diffie-hellman-group-exchange-sha* are optimized, up to a factor
of 11 for the slowest ( = biggest and safest) group size.
* dialyzer: The peak memory consumption is reduced. Analyzing
modules with binary construction with huge strings is now much
faster.
* erts: A received SIGTERM signal to beam will generate a 'stop'
message to the init process and terminate the Erlang VM nicely.
This is equivalent to calling init:stop/0.
* kernel: The functions in the file module that take a list of
paths (e.g. file:path_consult/2) will now continue to search in
the path if the path contains something that is not a directory.
* kernel: Two OTP processes that are known to receive many
messages are rex (used by rpc) and error_logger. Those processes
will now store unprocessed messages outside the process heap,
which will potentially decrease the cost of garbage collections.
* public_key: New function pkix_verify_hostname/2,3 implements
certificate hostname checking. See the manual and RFC 6125.-
* public_key, ssh: The ssh host key fingerprint generation now
also takes a list of algorithms and returns a list of
corresponding fingerprints. See
public_key:ssh_hostkey_fingerprint/2 and the option
silently_accept_hosts in ssh:connect.
* ssl: Move PEM cache to a dedicated process, to avoid making the
SSL manager process a bottleneck. This improves scalability of
TLS connections.
* stdlib: filename:safe_relative_path/1 to sanitize a relative
path has been added. - Add missed scripts requires for erlang-epmd package - Update to 19.2.2:
* mnesia: Fixed crash in checkpoint handling when table was
deleted during backup. - Update to 19.2:
* stdlib: The new behaviour gen_statem has been improved with 3
new features: the possibility to use old style non-proxy
timeouts for gen_statem:call/2,3, state entry code, and state
timeouts. These are backwards compatible. Minor code and
documentation improvements has been performed including a
borderline semantics correction of timeout zero handling.
* ssl: Experimental version of DTLS. It is runnable but not
complete and cannot be considered reliable for production usage.
To use DTLS add the option {protocol, dtls} to ssl:connect and
ssl:listen.
* ssh: Extended the option silently_accept_hosts for ssh:connect
to make it possible for the client to check the SSH host key
fingerprint string. Se the reference manual for SSH.
* ~40 contributions since the previous service release OTP 19.1 - Update to 19.1:
* erts: Improved dirty scheduler support. A purge of a module
will not have to wait for completion of all ongoing dirty
NIF calls
* erts: Improved accuracy of timeouts on MacOS X
* kernel: Add net_kernel:setopts/2 and net_kernel:getopts/2 to
control options for distribution sockets in runtime
* asn1: Compiling multiple ASN.1 modules in the same directory
with parallel make (make -j) should now be safe
* httpd: support for PUT and DELETE in mod_esi
* ~30 contributions since 19.0 - Update to 19.0.4:
* erts: Fixed a race that could cause a lost wakeup of a process
that timed out in a receive ... after. This bug was introduced
in ERTS version 7.0.
* erts: Fixed segfault after writing an erl crash dump. - Update to 19.0:
* compiler, stdlib: New preprocessor macros *?FUNCTION_NAME,
?FUNCTION_ARITY*. New preprocessor directives -error(Term) and
- warning(Term) to cause a compilation error or warning,
respectively.
* gen_statem: a new state machine behavior
* mnesia_ext: plugin of external storage solutions to mnesia
* crypto: uses EVP interface in OpenSSL resulting in generally
better performance and support for HW acceleration
* ssh: performance improvements, uses the new gen_statem behavior
* ssl: enhanced error log messages
* dialyzer: the support for maps is very much extended both
the type specification syntax and the type analysis.
* erts: erlang:open_port(spawn, ...) 3-5 times faster
* erts/kernel: Experimental support for Unix Domain Sockets
* ose: Deprecated application has been removed
* webtool: Deprecated application has been removed
* test_server: Deprecated application has been removed, use
common_test instead - Do not suppress errors from useradd/groupadd
- Orthographic/typographical fixes - Update to 18.3.4:
* inets: Handle multiple \t in mime types file
* ssl: Correct ssl:prf/5 to use the negotiated cipher suite's prf
function in ssl:prf/5 instead of the default prf.
* ssl: Timeouts may have the value 0, guards have been corrected
to allow this
* ssl: Change of internal handling of hash sign pairs as the used
one enforced to much restrictions making some valid
combinations unavailable.
* ssl: Create a little randomness in sending of session
invalidation messages, to mitigate load when whole table is
invalidated. - Return diameter application: as for 18.3.3 it is distributed
under APL license - Update to 18.3.3:
* common_test: The nodelay option used to be enabled (true) by
default for sockets opened by the Common Test
telnet client.
* common_test: Fix bug in cth_surefire
* common_test: The ct:get_timetrap_info/0 function has been
updated to return more information about timetrap
scaling.
* common_test: A problem with stylesheet HTML tags getting
incorrectly escaped by Common Test has been
corrected.
* common_test: The ct_run start flag -no_esc_chars and
ct:run_test/1 start option {esc_chars,Bool} have
been introduced.
* inets: Put back unused module inets_regexp
* ssl: Correct cipher suites conversion and gaurd expression. - Update to 18.3.2:
* inets: Add environment information item peer_cert to mod_esi
* ssl: Corrections to cipher suite handling using
the 3 and 4 tuple format
* ssl: Make values for the TLS-1.2 signature_algorithms
extension configurable - Update to 18.3:
* New statistics info about runnable and active processes &
ports. Call erlang:statistics with:
total_run_queue_lengths | run_queue_lengths | total_active_tasks
| active_tasks.
* Time warp improvements: dbg:p/2 and erlang:trace/3 with
monotonic_timestamp |strict_monotonic_timestamp.
* Introduced a validation callback for heart.
* The module overload in sasl has been deprecated.
* several bug fixes - Update to 18.2.3:
* inets: mod_alias now traverses all aliases picking
the longest match and not the first match. - Update to 18.2.2:
* ssh: The authentication method 'keyboard-interactive' failed
in the Erlang client when the server after successful
authentication continued by asking for zero more
passwords. - Update to 18.2.1:
* Due to a bug in the handling of paths on windows
none of the following would work with paths
containing a space: ct_run dialyzer erlc escript typer
This also contains a fix for HiPE enabled emulator for
FreeBSD.
- Update to 18.2:
* ssl: Add configurable upper limit for session
cache. erts: Add function enif_getenv to read OS
environment variables in a portable way from NIFs.
* kernel: Add {line_delim, byte()} option to
inet:setopts/2 and decode_packet/3
* ssh: The 'ecdsa-sha2-nistp256',
'ecdsa-sha2-nistp384' and 'ecdsa-sha2-nistp521'
signature algorithms for ssh are implemented. See RFC5656.
* ssh: The ssh:daemon option dh_gex_groups is
extended to read a user provided ssh moduli file
with generator-modulus pairs. The file is in openssh
format. - disable hipe on s390/s390x to fix build - Update to 18.1.3:
* ssl: Add possibility to downgrade an SSL/TLS connection to a
tcp connection, and give back the socket control to a user
process.
* ssh: The following new key exchange algorithms are
implemented:'ecdh-sha2-nistp256', 'ecdh-sha2-nistp384',
'ecdh-sha2-nistp521','diffie-hellman-group14-sha1',
'diffie-hellman-group-exchange-sha1' and
'diffie-hellman-group-exchange-sha256'. This raises the
security level considerably.
* kernel,stdlib,sasl: A mechanism for limiting the amount of
text that the built-in error logger events will produce has
been introduced. It is useful for limiting both the size of
log files and the CPU time used to produce them. This
mechanism is experimental in the sense that it may be changed
based on feedback. See config parameter
error_logger_format_depth in the Kernel application.
- Removed erts_fix_unlock_status_lock.patch: fixed in upstream - Rework wxWidgets BuildRequire: fix build for Leap 42.1 - update to 18.0.3:
* erts: Fixed a binary memory leak when printing to shell using
the tty driver (i.e. not -oldshell).
* erts: Fix a bug where the standard error port sometimes
crashes with eagain as the reason. - add erts_fix_unlock_status_lock.patch to fix a rare deadlock in erts - fix RHEL/CentOS 7 build - update to 18.0.2:
* Fix processes ending up in an inconsistent half exited state
in the runtime system without SMP support
* Remove unnecessary copying of data when retrieving corrected
Erlang monotonic time.
* POTENTIAL INCOMPATIBILITY:
Change default OS monotonic clock source chosen at build time.
This in order to improve performance. The behavior will now on
most systems be that (both OS and Erlang) monotonic time stops
when the system is suspended. (changeable via the
- -enable-prefer-elapsed-monotonic-time-during-suspend
configure parameter)
* Fix erlang:system_info(end_time) returning a faulty value on
32-bit architectures.
* Fix the trace_file_drv not handling EINTR correctly which
caused it to fail when the runtime system received a signal. - update to 18.0.1:
* Fix a rare hanging of the VM seen to happen just after
emulator start. Bug exists since R14. - update to 18.0:
* new license: APL 2.0 (Apache Public License)
* erts: The time functionality has been extended. This includes
a new API for time, as well as "time warp" modes which
alters the behavior when system time changes. You are
strongly encouraged to use the new API instead of the
old API based on erlang:now/0. erlang:now/0 has been
deprecated since it is a scalability bottleneck. See
http://www.erlang.org/doc/apps/erts/time_correction.html
* erts: Beside the API changes and time warp modes a lot of
scalability and performance improvements regarding time
management has been made. Examples are:
+ scheduler specific timer wheels,
+ scheduler specific BIF timer management,
+ parallel retrieval of monotonic time and system time
on OS:es that support it.
* erts: The previously introduced "eager check I/O" feature is
now enabled by default.
* erts/compiler: enhanced support for maps. Big maps new uses a
HAMT (Hash Array Mapped Trie) representation internally
which makes them more efficient. There is now also
support for variables as map keys.
* dialyzer: The -dialyzer() attribute can be used for suppressing
warnings in a module by specifying functions or warning
options. It can also be used for requesting warnings in
a module.
* ssl: Remove default support for SSL-3.0 and added padding check
for TLS-1.0 due to the Poodle vulnerability.
* ssl: Remove default support for RC4 cipher suites, as they are
consider too weak.
* stdlib: Allow maps for supervisor flags and child specs
* stdlib: New functions in ets:
+ take/2: Works the same as ets:delete/2 but also returns
the deleted object(s).
+ update_counter/4 with a default object as argument - update to 17.5.6:
* Fix broken relay counters
* Fix diameter_sctp listener race
- fix build for SLE_12 - Update to 17.5.4 - fix systemd service files for epmd:
* fix stop of epmd (epmd -kill is deprecated and ignored, so stop hangs) - Update to 17.5:
* ERTS: Added command line argument option for setting the
initial size of process dictionaries.
* Diameter: configurable incoming_max len and string_decode for
diameter messages
* Bugfixes and minor small features in applications such as
compiler, common_test, crypto, debugger, eldap, erts, hipe,
inets, ssh, ssl, ...
- remoce ct-fix_incl-dirs.patch (included upstream) - add ct-fix_incl-dirs.patch (upstream patch for common test) - Version 17.4:
* eldap: Nearly all TCP options are possible to give in the eldap:open/2 call.
* ssh: Added API functions ptty_alloc/3 and ptty_alloc/4, to allocate a pseudo tty.
* ssl: Handle servers that may send an empty SNI extension to the client. - use wxWidgets 3.0 - fix bashisms in pre script s390zp3a 1717990558
