https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256393 --- Comment #18 from Alexander V. Chernikov <melifaro@FreeBSD.org> --- (In reply to Nathan Whitehorn from comment #12) Interesting. Are you absolutely sure it's stock 13-S? Any custom sysctl's / multiple fibs ? The logs above show commit https://cgit.freebsd.org/src/commit/sys/net/route/route_ifaddrs.c?h=stable/13&id=ae23d302479 , but does not explicitly specify the hostname (in that line). Currently loopback routes in 13-S are PINNED: https://cgit.freebsd.org/src/tree/sys/net/route/route_ifaddrs.c?h=stable/13&id=ae23d302479#n163 , so it shouldn't be possible for routed(8) to delete such routes. PINNED logic also should take precedence over any other non-PINNED routes, allowing to replace these on route addition during interface address assignment. Could you by any chance show the following: 1) netstat -4rnW, netstat -4onW 2) route -n monitor 3) if possible, run `dtrace -i 'fbt:kernel:*:return /arg1==17/ {stack()}'` 4) Run commmand-to-fail: `ifconfig tun0 192.168.42.1 192.168.42.2` 5) netstat -4rnW, netstat -4onW -- You are receiving this mail because: You are on the CC list for the bug.
