[Dnsmasq-discuss] FreeBSD TFTP issue (failure to serve via IPv4) reported against 11.3/12.x

Greetings,

I have received a bug report where TFTP regresses on newer FreeBSD
versions and breaks on 11.3 and 12.0 with IPv4 where older FreeBSD
releases (that are now weeks before EOL) work,
with some kind of analysis, here:

<https://forums.freebsd.org/threads/dnsmasq-tftp-service-not-working-any-longer.72457/#post-440976>
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241068>

Please investigate. I don't currently have time to look deeper and/or
debug.
It appears that IPv6 works but something about interface enumeration is
broken with IPv4 and the relevant interface isn't found.
Might have to do with sizing of structures.

I can't currently look deeper, but should be able to answer questions or
try patches tomorrow.
It seems the minimal reproducer forward would be to install FreeBSD 11.3
in a VM and test locally with a TFTP client pulling from 127.0.0.1 to
force IPv4 and ::1 to force IPv6.

Regards,
Matthias
