I've put together a little script that I've attached that I'm using to test the driver.. It puts a couple ue interfaces each into their own jail, configures them, and tries to pass traffic. This assumes that the two interfaces are connected together. Pretty regularly when destroying the jails, I get the following panic: CURVNET_SET at /usr/src/sys/netinet/in_mcast.c:626 inm_release() curvnet=0 vnet=0xfffff80154c82a80 (kgdb) #0 __curthread () at /usr/src/sys/amd64/include/pcpu_aux.h:55 #1 doadump (textdump=1) at /usr/src/sys/kern/kern_shutdown.c:394 #2 0xffffffff80bc6250 in kern_reboot (howto=260) at /usr/src/sys/kern/kern_shutdown.c:481 #3 0xffffffff80bc66aa in vpanic (fmt=, ap=) at /usr/src/sys/kern/kern_shutdown.c:913 #4 0xffffffff80bc6403 in panic (fmt=) at /usr/src/sys/kern/kern_shutdown.c:839 #5 0xffffffff80d6553b in inm_release (inm=0xfffff80029043700) at /usr/src/sys/netinet/in_mcast.c:630 #6 inm_release_task (arg=, pending=) at /usr/src/sys/netinet/in_mcast.c:312 #7 0xffffffff80c2521a in taskqueue_run_locked (queue=0xfffff80003116b00) at /usr/src/sys/kern/subr_taskqueue.c:476 #8 0xffffffff80c26294 in taskqueue_thread_loop (arg=) at /usr/src/sys/kern/subr_taskqueue.c:793 #9 0xffffffff80b830f0 in fork_exit ( callout=0xffffffff80c26200 , arg=0xffffffff81cf4f70 , frame=0xfffffe0049e99b80) at /usr/src/sys/kern/kern_fork.c:1052 #10 (kgdb) I have the core files so I can get additional information.
