--- Comment #7 from Arne Steinkamm <a...@steinkamm.com> ---
I can reproduce this panic with 12.0-RELEASE-p7 r350232 and a pretty forward
out-of-the-handbook Jail setup.
This should be enough to get a nasty panic:
Host:
/etc/rc.conf:
[...]
vlans_em0="vlcx0"
create_args_vlcx0="vlan 18"
ifconfig_em0="up"
ifconfig_vlcx0="inet 10.8.8.110 netmask 255.255.255.0"
[...]
jail_enable="YES"
jail_confwarn="YES"
jail_parallel_start="NO"
jail_list="jv"
jail_reverse_stop="YES"
---------------------------------------------------------------------
/etc/jail.conf:
exec.start = "/bin/sh /etc/rc";
exec.stop = "/bin/sh /etc/rc.shutdown";
exec.clean;
jv {
host.hostname = "julesverne.stk.cx";
path = "/var/local/prison/jv";
exec.clean;
exec.system_user = "root";
exec.jail_user = "root";
vnet;
exec.clean;
vnet.interface = "ng0_jv";
exec.system_user = "root";
exec.jail_user = "root";
exec.prestart += "/l/om/sbin/jng bridge jv em0";
exec.poststop += "/l/om/sbin/jng shutdown jv";
# Standard stuff
exec.consolelog = "/var/local/log/jails/jv_console.log";
mount.devfs; #mount devfs
allow.raw_sockets; #allow ping-pong
devfs_ruleset="5"; #devfs ruleset for this jail
mount.devfs;
}
--------------------------------------------------------------------
Jail /etc/rc.conf:
[...]
ifconfig_ng0_jv="up"
vlans_ng0_jv="jjvcx0"
create_args_jjvcx0="vlan 18"
ifconfig_jjvcx0="inet 10.8.8.190 netmask 255.255.255.0"
[...]
/l/om/sbin/jng is a copy of /usr/src/share/examples/jails/jng
This should be everything you need to get exact the panic described in this bug
report.
