Hi,
today i upgraded my primary router from OpenBSD 5.4 to OpenBSD 5.5 (i
follow the process described here:
http://www.openbsd.org/faq/upgrade55.html and this is my 5th upgrade
from 5.4 to 5.5 since the release).
After rebooting and doing the sysmerge without network copper cables, i
rebooted and set my carp & pfsync interfaces to down before plugging the
cables. At this time, the router was in a CARP INIT mode, no problem.
Note: all the traffic was redirected to my second OpenBSD router (which
was upgraded at release time) 3 days ago, this routers hasn't any
problem and have exactly the same hardware and software configuration
(except some IPs).
After finishing the upgrading process, i have incremented the carpdemote
counter to force CARP to be in BACKUP mode and then i have set all my
carp interface to up. Then ifaces were in BACKUP mode. No problem since
there all was right, all services works fine, etc.
The last step i do is to do a "ifconfig pfsync0 up" and then a OpenBSD
crash.
Following you can found the trace, the ps and the registers.
I haven't seen any errata for pfsync, then i didn't patched the kernel,
it's the GENERIC BSD.MP.
Is there any workaround ? A kernel patch to apply ?
Thanks in advance
