OpenBSD 6.5 dumps to debugger when using ifconfig bridge command

Russell Sutherland
I began to install resflash (https://stable.rcesoftware.com/resflash/) which is based on OpenBSD) to build a small firewall on an PC Engines apu2 board. Three interfaces, two bridged and one with an IP for management.

I found the system would crash and drop down to the debugger interface whenever I issued the:

# ifconfig bridge0

command.

# ifconfig -a

worked fine. After discussing this with the author we thought it good to try the same configuration on vanilla 6.5 install.

This worked better, but after a short period of operation the same symptoms occured:

# ifconfig bridge0

bridge0: flags=4WAR1<UP,RUNNING>

        Nindex 6 llprio ING: SPL NOT

        groups: bridgLOWEe

        priority 327RED68 hellotime 2 f ONwddelay 15 maxag e 20 holdcnt 6 pSYSCALL 5roto rstp

        desi4gnated: id 00:0 3 EXIT 0:00:00:00:00 pri 9

                                                       ority 0

Here is the output from dmesg:

Re: OpenBSD 6.5 dumps to debugger when using ifconfig bridge command

Tom Smyth
Hi Russell
I had this issue when bridging vio()  interfaces  in kvm / proxmox ...  but
not with em() interfaces
can you try with a uni-processor kernel ...  to see does it crash /  dump
?   mpi@ had asked me to enable witness in the kernel and send the output
of the dumps
(I haven't gotten around to  that yet ) ...

Re: OpenBSD 6.5 dumps to debugger when using ifconfig bridge command

lnelson
In reply to this post by Russell Sutherland
I have twice seen kernel panics in the same situation. It drops to "ddb>"
but the system is unresponsive. Unfortunately, other than taking a picture
of the screen with my cellphone, I do not have any further information from
the system. On both occasions, I was issuing "ifconfig bridge42" without
any arguments. (and no, there aren't 41 other bridges. 42 has other
significance in my network)

Re: OpenBSD 6.5 dumps to debugger when using ifconfig bridge command

Stuart Henderson
There was a crash fixed in bridge(4) a few weeks ago, can you try reproducing
on -current?
