20.7 Legacy Series / Re: radvd crash loop

« on: August 24, 2020, 12:08:22 pm »

Hello,

just to report that so far so good. No more crash of the interface or radvd since the hardware accel was disabled on the interface.
When I'll have more time, I may dig into this to check which option is causing this. It's a shame that the freebsd manpage for this module advertise the hardware/software compatibility for these options though.

Anyway, thanks to both of you.

Thanks gpb,

I'll try that and report back. I put faith in the driver support from freebsd, but that may be broken indeed.

Thanks for the reply gpb and franco.

I should have detailed the setup a bit more.

My wan interface (igb0_vlan832) obtains IPv4/6 by DHCP
LAN interface (igb1 physical nic, with several trunked vlan) : Static IPv4 for all and "track interface" (wan) for IPv6 for 3 of them
Then Router Advertisements is configured as "unmanaged" (SLAAC) for these 3 vlan.

I've looked at the system log during the event, and I noticed a link state change on my lan port which I can't explain. Could it be an hardware issue ?
The box running opnsense is a well-known Qotom device, having 4 Intel I211 nics. So using the igb driver, and according https://www.freebsd.org/cgi/man.cgi?igb(4) I enabled Checksum offload, TSO, and HW vlan acceleration.

The system.log grep'd on the same timeframe is too verbose to put it here, so please find it on posted on pastebin :

20.7 Legacy Series / radvd crash loop

« on: August 18, 2020, 06:58:45 pm »

Hello, and please excuse me if this is not in the correct section.

I'm facing an issue with my setup, which I hoped would disappear with the upgrade to 20.7 but it's still there and it's driving me nuts.
I'm not really sure when it all started, but somewhere after the 20.1 I think.
I have a working v4/v6 setup, but sometimes i'm loosing v6 connectivity because radvd enters a crash loop, and I have to restart the service for my lan devices to get an IPv6 again.

I have absolutely no clue on what might be the issue.
I'm confident enough with the OS to do some debug, but I would gladly have advices on what/where to look for.

Here you can see the /var/log/routing.log, it's stop/start looping for several minutes, then settle (but not working as there are no RA on the LAN), until I finally restart from the GUI, and my LAN servers receive their IPv6
