top of ZVOLs. The problem is that rc.d/fsck runs before rc.d/zfs. The
latter makes ZVOLs to appear in /dev/. In such case rc.d/fsck cannot
find devfs entry and aborts. We cannot simply move rc.d/zfs before
rc.d/fsck, because we first want kern.hostid to be configured (by
rc.d/hostid). If we won't wait (hostid will be 0) we can reuse disks
which are in use by different systems (eg. in SAN/NAS environment).
We also cannot move rc.d/hostid before rc.d/fsck, because rc.d/hostid on
first system start stores generated kern.hostuuid in /etc/hostid file,
so it needs root file system to be mounted read-write.
The fix is to split rc.d/hostid so that rc.d/hostid (which will now run
before rc.d/fsck) only generates hostid and sets up sysctls, but doesn't
touch root file system and rc.d/hostid_save (which is run after
rc.d/root) and only creates /etc/hostid file.
With that in place, we can move ZVOL initialization to dedicated
rc.d/zvol script which runs before rc.d/fsck.

Receipt of a specially-crafted dynamic update message may

servers -- it is not limited to those that are configured to
allow dynamic updates. Access controls will not provide an
effective workaround.

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.
