I am running 8.2 , I am hitting a panic after I create a vnet jail an try to remove it. jail -c name=j1 children.max=20 host.hostname=j1 jid=100 vnet persist allow.raw_sockets jail -r j1
calltrap() at calltrap+0x8 --- trap 0x9, rip = 0xffffffff80518f4d, rsp = 0xffffff805fa1d9e0, rbp = 0xffffff805fa1da30 --- raw_input() at raw_input+0x4d rts_input() at rts_input+0x70 netisr_process_workstream_proto() at netisr_process_workstream_proto+0x1ea swi_net() at swi_net+0xad intr_event_execute_handlers() at intr_event_execute_handlers+0x21c ithread_execute_handlers() at ithread_execute_handlers+0x73 ithread_loop() at ithread_loop+0x10f fork_exit() at fork_exit+0x180 fork_trampoline() at fork_trampoline+0xe The issue seems to be that in if_detach_internal(), if_down() is called which leads to netisr_queue() call in rt_dispatch() with an mbuf which has the interface being detached as rcvif, subsequently if_detach_internal() calls if_dead() on the interface. And, then at time of processing the work, this panic is seen since mbuf has a dead interface. The same issue has been reported on the virtualization mailing list earlier and I reported it to freebsd-net as well. Here are the threads: http://lists.freebsd.org/pipermail/freebsd-virtualization/2012-April/000885.html http://www.mail-archive.com/[email protected]/msg43045.html Thanks for any help! -Suraj Sandhu _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-jail To unsubscribe, send any mail to "[email protected]"
