in prison_equal_ip4/6 while an inp mutex was held. Locking allprison_lock
can be avoided by making a restriction on the IP addresses associated with
jails:
Don't allow the "ip4" and "ip6" parameters to be changed after a jail is
created. Setting the "ip4.addr" and "ip6.addr" parameters is allowed,
but only if the jail was already created with either ip4/6=new or
ip4/6=disable. With this restriction, the prison flags in question
(PR_IP4_USER and PR_IP6_USER) become read-only and can be checked
without locking.
This also allows the simplification of a messy code path that was needed
to handle an existing prison gaining an IP address list.

L2 information. For an indirect route the cached L2 entry contains the
MAC address of the gateway. Typically the default route is used to
transmit multicast packets when explicit multicast routes are not
available. The ether_output() function bypasses L2 resolution function
if it verifies the L2 cache is valid, because the cached L2 address
(a unicast MAC address) is copied into the packets as the destination
MAC address. This validation, however, does not apply to broadcast and
multicast packets because the destination MAC address is mapped
according to a standard method instead.

processing code holds the read lock (when processing a
FWD-TSN for pr-sctp). If it finds stranded data that
can be given to the application, it calls sctp_add_to_readq().
The readq function also grabs this lock. So if INVAR is on
we get a double recurse on a non-recursive lock and panic.
This fix will change it so that readq() function gets a
flag to tell if the lock is held, if so then it does not
get the lock.

from going away, under INVARIANTS as this is a general problem
of the stack and should be solved in if.c/netisr but still good

(ifconfig ifN (-)vnet <jname|jid>) work correctly.
Move vi_if_move to if.c and split it up into two functions(*),
one for each ioctl.
In the reclaim case, correctly set the vnet before calling if_vmove.
Instead of silently allowing a move of an interface from the current
vnet to the current vnet, return an error. (*)
There is some duplicate interface name checking before actually moving
the interface between network stacks without locking and thus race
prone. Ideally if_vmove will correctly and automagically handle these
in the future.
