Martin -
What's your configure line for freebsd? Can you point me at your
config.log for this build? My freebsd vm is unhappy with me right
now.
That’s where I have issues. My CI integrated system spots the error
(and every time), but if
I try to run it outside, then it seems to work.
Current config inside the CI system is as follows:
--enable-user=quagga --enable-group=quagga
--sysconfdir=/usr/local/etc/quagga-test --localstatedir=/var/run/quagga
--enable-vtysh
--with-pkg-extra-version=-ci.NetDEF.org-20160223.101813-git.04a3aab
--enable-fpm --enable-tcp-zebra --disable-irdb --enable-isisd
--enable-isis-topology --enable-bgp-announce --enable-opaque-lsa
--without-libpam --enable-pimd --enable-rtadv --disable-snmp
--enable-tcp-zebra --prefix=/usr/local --mandir=/usr/local/man
--infodir=/usr/local/info/ --build=amd64-portbld-freebsd10.1
Still trying to reproduce it outside of the automated system (so I can
do
more troubleshooting)
(The automated CI system uses my CI plans to build packages, then
installs them
and uses them for the tests. When I do it outside of CI system I’m
just doing
the usual make/make install and usually with less optimization to get
debug
info)
This bug affects at least 3, probably more BGP errors
Anyway, beside of someone looking at the specific patch and see if
something
might go wrong on FreeBSD, I just need a bit more time to reproduce it.
Hope to know more in another 8..12 hrs.

Martin -
Any word on this? I'd like to push this patch if it fixes your
issues.
Not yet.
I’m dealing with (most likely) several issues which seem overlap.
So it
takes a bit
more time.
I still tend to think that Timo’s fix is good - but only addressing
part
of the problems.
I’ll prefer to keep it on hold at this time until at least one more
FreeBSD bug is fixed.
One of the git bisect on BGP errors pointed to commit

vrf: add a runtime check before playing with netns
This patch adds a runtime check to determine if netns are
available. Some
systems like OpenWRT have the system call setns() but don't
have the kernel
option CONFIG_NET_NS enabled.

Doing a git bisect points to this commit breaking at least 3 BGP
tests.
I’m still trying to manually verify and understand how this breaks
it, so
give me
more time.
(Feel free to guess on how this commit could break FreeBSD… seems
to be
related
to similar not correctly installing forwarding entries as well)

rt_socket.c is not compiled on linux so no need for verification.
Once
you
have a run please let me know and I'll push your updated patch.
It’s running now. Will know soon. It definitely fixes some of the
errors
and I hope it actually fixes all of the FreeBSD errors.
Will know in approx one more day.
(BTW: Testing on a git commit which does no longer exist because of
rebase,
but I needed the same to compare. Lucky that I still had the VMs
with the
old git checkout running…)

This is based on Quagga proposed 6 branch of Feb 10 (git

Zebra seems to fail delete any routes in FreeBSD RIB. It fails
with
updates (better routes to different interface) and
it fails to remove them when quagga is killed.
Thanks for the testing. Sounds like this is breakage caused by
my
atomic FIB patch which was pretty untested on *BSD.
Looks like the code talking to kernel does not handle RTM_CHANGE
correctly. As first test, perhaps just removing RTM_CHANGE usage
might
fix the issues and revert to how it used to work.
Using RTM_CHANGE on kernels where it works is better, but it's
left an
exercise for developer who has access and will to fix it on
*BSD.
Thanks for the patch. Seems like you never tested it (failed to
compile),
but was close enough to guess what you probably meant. See inline

With the changes it fixes the specific issue I’ve mentioned. I
have not
verified the
patch on Linux yet. Will do a full run with this patch to see how
many
of
my approx
20..30 failing FreeBSD testcases it fixes (I assume many to
all…)
