Hi Bjoern,
I apologize for not including this information originally. This is
the 7.0-RELEASE patch but I applied it against a kernel with the memory
limits patch already in place. I had to manually merge most of
kern_jail.c by hand.
I tried again to start a jail and found that I could run the following
and it works as you demonstrated.
[root@virt] ~ # jail -n test1 /usr/jail/4001/ test1
208.86.224.219,10.11.40.2 /sbin/ifconfig -a
priv0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:30:48:c2:89:2a
inet 10.11.40.2 netmask 0xffffffff broadcast 10.11.40.2
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
pub0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:30:48:c2:89:2b
inet 208.86.224.219 netmask 0xffffffff broadcast 208.86.224.219

status: active
That is one IP each from two interfaces. I tried with two from the
public interface and one from the private interface and then it failed
to assign the address on the private interface. All necessary aliases
have been created.
[root@virt] ~ # jail -n test1 /usr/jail/4001/ test1
208.86.224.219,208.86.224.220,10.11.40.2 /sbin/ifconfig -a

Other combinations give other strange results. Assigning two address
from each interface resulted in two being assigned to the private
interface but only one to the public interface. I'm not sure what's
going on or if I'm just doing something stupid but any insight would be
appreciated.
Much Thanks,
Chris
