[Bug 276870] mbuf cluster leak with on pf+bird2 bgp routers
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=276870 Marek Zarychta changed: What|Removed |Added CC||oliv...@freebsd.org --- Comment #4 from Marek Zarychta --- Now, when we have only FreeBSD 13, 14 and CURRENT branches supported and all of them have reworked routing stack with NETLINK support included, bird2-netlink is better suited to run on FreeBSD and probably should become the default flavor of net/bird2 port. The transition is important to avoid such situations in the future. Netlink flavor supports ECMP, the memory footprint is much lower compared to rtsock version, and it will run with the same config file, though small config changes are recommended. The user experience with bird2-netlink is better since it can run undisturbed for months on FreeBSD 13.2+ without any observable drawbacks. -- You are receiving this mail because: You are on the CC list for the bug.

Lots of stuff merged between 384a885111ad and 2cbd132986a7. Thomas, is it possible for you to work more on isolating the regression? Things to check: 1) Did bird upgrade 2.0.9 to 2.14 switch bird to use NETLINK instead of route socket? If 1) is false, there are two options: 2.0.9 and 2.14 both used NETLINK or both used route socket. If the latter, than my guess is totally wrong and Mark's guess is much better. If the former, than we need to bisect between 384a885111ad and 2cbd132986a7. 2) If 1) is true, then please compile 2.14 with NETLINK disabled and check if leak has gone. If 1) and 2) are true it could be the problem was in 384a885111ad as well, but you did not use NETLINK. 3) Check if running with NETLINK on 384a885111ad reproduces the leak or not? (Be careful, as lots of bugs were removed after 384a885111ad) Depending on 3) we may need to run bisection. Anyway, please keep us updated when you got more info, starting with 1). -- You are receiving this mail because: You are on the CC list for the bug.

There's no mention of pf except in the bug title. > I at one point tried adding the missing kernel export filter (as to at least > silence the noisy warnings in the logs), and imagine my surprise when the > mbuf cluster leak stopped. I'm not too familiar with how this works - does this basically install a bunch of routes in the kernel, so most likely you're hitting an mbuf leak in the routing socket code? This may be fixed in 14.0 by virtue of having reimplemented parts of that interface using netlink. -- You are receiving this mail because: You are on the CC list for the bug.
