Kristof Provost <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #4 from Kristof Provost <[email protected]> --- I believe this is the same issue as #279653 and #291003. We've also seen it on pfsense (https://redmine.pfsense.org/issues/14431). I believe the first reports there started about two years ago. At the time I stuck this workaround in the pfsense tree: https://github.com/pfsense/FreeBSD-src/commit/9834d8bb0d3344cd82552c3cd16e5b2d84543d8f (That's very much a workaround and not a fix, but it does seem to have greatly reduced the impact for pfsense users) My suspicion is that it's a race around interface destruction, where we somehow still end up getting a route from fib6_lookup() on an interface that no longer has afdata for AF_INET6, but I never worked out how we could end up in that state. We also never managed to get a reliable reproduction scenario. If Justin can reproduce this it'll be important progress. -- You are receiving this mail because: You are the assignee for the bug.
