ipv6 broken: radvd: can't join ipv6-allrouters on <interface>

bimmerdriver

I'm running the latest development release:

2.5.0-DEVELOPMENT (amd64)
built on Wed Jun 03 13:09:01 EDT 2020
FreeBSD 12.1-STABLE

This morning, I noticed the routing log filled with this message:

Jun 7 10:01:16 radvd 76671 can't join ipv6-allrouters on hn1

IPv6 was not working. I rebooted and the system is now working.

@bimmerdriver Still waiting for workaround ports PR #773 to be accepted and applied.

I also notice many messages like "Jun 11 11:02:57 pfSense radvd[84278]: can't join ipv6-allrouters on ix1.116"

However I would like to add:

after installing the 3 june package a few days ago ..... they were gone
today I installed the 10 june package and they where back
and I did have an IPV6 routing problem ...
than I did a reboot and ... the messages where gone
and my IPV6 routing issue seems to be gone

Note that this is not at all an real test, just a quick obeservation.

The routing log was full of the messages this morning, so the problem is still present.

As @rschell said https://github.com/pfsense/FreeBSD-ports/pull/773 still need to be applied, but it's not accepted and applied yet.

I updated Redmine issue #9577 with a revised RADVD install package for those continuing to experience problems. I left instructions there how to install.

I have had installs run for more than 35 days with the revised RADVD only to stop it to install new 2.5 updates..

@w0w I tried to apply the patch to 2.5.0-development using this commit ID: https://github.com/pfsense/FreeBSD-ports/pull/773/commits/387a6ef1e4fd514596502e162878f64f0002170c, but it could not be applied. Am I doing something wrong?

A Former User

@bimmerdriver Not sure, I rebase my git with every update and it works here.
Are you applying it to the ports Git? What errors are you getting?

bimmerdriver

@rschell I didn't do anything with git. I tried to apply the patch directly to the development snapshot and it failed. I guess that's the problem.

A Former User

@bimmerdriver it’s applying changes to the C code of RADVD, so it needs to be compiled. I have uploaded a compiled version to redmine. You can install that package and it will survive most updates except full port replacements.

@rschell thank you - your patch fixed up my issues. Hopefully this gets pulled into main soon.

bimmerdriver

@rschell Thank you, sir. It's installed and I will keep an eye on it.
