https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228501 --- Comment #8 from Marie Helene Kvello-Aune <marieheleneka@gmail.com> --- Confirmed: There's no panic when repeatidly starting&stopping the jail w/o = an IP assigned to epair0b. If I assign an IP to epair0b (I did so through the jails rc.conf), start the jail, then stop it; there's an immediate panic: negative refcount. During this test, no network daemons were enabled, sendmail was explicitly disabled, and syslogd were passed the "-ss" flags upon startup. =3D=3D Panic summary =3D=3D panic: negative refcount 0xfffff8001d12803c cpuid =3D 0 time =3D 1527428596 KDB: stack backtrace: db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe0077b96= 660 vpanic() at vpanic+0x1a3/frame 0xfffffe0077b966c0 doadump() at doadump/frame 0xfffffe0077b96740 ifa_free() at ifa_free+0x35/frame 0xfffffe0077b96760 in_difaddr_ioctl() at in_difaddr_ioctl+0x460/frame 0xfffffe0077b967c0 in_ifscrub_all() at in_ifscrub_all+0xff/frame 0xfffffe0077b96850 ip_destroy() at ip_destroy+0xbd/frame 0xfffffe0077b96870 vnet_destroy() at vnet_destroy+0x12c/frame 0xfffffe0077b968a0 prison_deref() at prison_deref+0x29d/frame 0xfffffe0077b968e0 taskqueue_run_locked() at taskqueue_run_locked+0x14c/frame 0xfffffe0077b969= 40 taskqueue_thread_loop() at taskqueue_thread_loop+0x88/frame 0xfffffe0077b96= 970 fork_exit() at fork_exit+0x84/frame 0xfffffe0077b969b0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe0077b969b0 --- trap 0, rip =3D 0, rsp =3D 0, rbp =3D 0 --- KDB: enter: panic Additional info about jail: # jexec devsamba sockstat -l USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS root casperd 28345 7 stream /var/run/casper root syslogd 26069 5 dgram /var/run/log root syslogd 26069 6 dgram /var/run/logpriv --=20 You are receiving this mail because: You are the assignee for the bug.=
