OpenBSD 6.9 errata 023, December 7, 2021:

Errata 021 broke rpki-client(8) compatibility with bgpd(8)

Apply by doing:
    signify -Vep /etc/signify/openbsd-69-base.pub -x 023_rpki.patch.sig \
        -m - | (cd /usr/src && patch -p0)

And then rebuild and install rpki-client
    cd /usr/src/usr.sbin/rpki-client
    make obj
    make
    make install
