ipv6 broken: radvd: can't join ipv6-allrouters on <interface>
-
A couple of thoughts:
-
The call to “setup_allrouters_membership” is being called several hundred times an hour. Should it be more selective when it asks to join a group rather than repeated leaving and joining? Think that is just asking for trouble we are seeing.
-
There are a number of upstream commits that have been applied to stable/12 since releng/12 in in6_mcast.c that suggest there are issues lurking there.
-
-
yes, indeed..
i'm sure it will be ok sooner or later, it's a development snapshot after all, we have our workaround in the meantime. they are aware of the problem and i'm using it at home so it's not a priority for me at the moment -
@kiokoman the problem is within open source or kernel code, so who are "they" who will fix it?
-
If radvd 2.17_5 works well, then the issue is isolated to radvd or radvd patches, I think. Let me test it and we will know it soon, am I right/wrong.
The fact that there is no spam inspires me with hope. -
sorry but if you check this
https://redmine.pfsense.org/issues/9577
you will see that we had 2.17 until 2019-07-22 with the same problem, it was updated to 2.18 at the end of july@irata i don't think that netgate will release a product with a broken service, they will find a way, or they ask upstream or with a patch they made

One thing that looks quite different for me is that radvd can't join routers right after start, not hours later as we have it now.EDITED: Oh yes, epic fail. -
@kiokoman I agree, 2.5 will be left in beta until someone fixes it.
-
@rschell good work about that update on redmine
personally i had decided to wait for 2.5 to advance before trying to do anything as any patch that we come out today it will probably be lost resulting in a waste of time as it is a kernel problem and not a pfsense's fault -
Ipv6 problem also caused problems with FRR
-
@rschell
I see you have some progress on 12.1 builds, but you did not report back on redmine, is it working? -

@rschell
I see you have some progress on 12.1 builds, but you did not report back on redmine, is it working?I have updated #9577, but for some reason the issue doesn't showup on the 2.5 issue list anymore. My version is running well and RADVD continues to work past 24 hours. The version is built on releng/12.1-RC2 with cherry-picked commits from 2.5 back to mid-February.
Once the pfSense is rebased on releng/12.1 or stable/12 and the message logging in RADVD is removed, these problems should be resolved.

I haven't used FRR, so I can't speak to whether this will resolve those issues.

@rschell
frr use with openvpn ipv6 has issue, add two ipv6 Neighbor openvpn will happen.

@jimp, any news? Did Netgate choose the FreeBSD version already? 12.1 is released a few days ago.
-
We are aware of the release (The FreeBSD Release Engineer is a Netgate employee :-)
12.1 is the current plan but there may be some parts picked back from stable. We'll see how things shake out.
-
@jimp Hmm, missed that reddit post, thanks a lot for the information!

@jimp Hmm, missed that reddit post, thanks a lot for the information!
Any clue why #9577 is not showing up on the issue list anymore?
It might be better to split the redmine issue into two since there is spamming log issue and a FreeBSD 12.0 issue?
-
In net/radvd of Ports, remove logging of "IPv6 forwarding" in interface.c since "check_ip6_iface_forwarding" routine is stubbed out in "radvd/device-bsd44.c". This is unrelated to the FreeBSD 12 version
-
Upgrade network interfaces including netinet6/in6_mcast.c to code in RELENG/12.1. The mcast changes in 12.1 are extensive enough to both ipv4 and ipv6 to prohibit back-porting (I tried). This second issue resolves the "can't join ipv6-routers" logging and permits RADVD to function beyond 24 hours.

-
so to fix this we need to update to 12.1 and that has 25% perf hit. ooof

@strangegopher
Not so bad, I think. May be it affects only maximum throughput, who knows, no further information at the moment. Also as @jimp mentioned, they can apply some fixes by picking up some parts from stable.@rschell
I've never checked was it listed before or not, but i don't see any changes made about that. May be it's because target version is missing? -
Any news about the problem/patch? I have this bug too, but too lazy/dont have time to go back to 2.4.4...
-
@havastamas
Waiting for the new builds based on 12.1 version of FreeBSD. I don't know if there any target date available.
Currently you can use workaround published by @kiokoman. I use it with cron package. Just running command every hour.
killall radvd && sleep 5 && /usr/local/sbin/radvd -p /var/run/radvd.pid -C /var/etc/radvd.conf -m syslog
