netlabel: Fix build problems when IPv6 is not enabled
A recent fix to the the NetLabel code caused build problem with
configurations that did not have IPv6 enabled; see below:
netlabel_kapi.c: In function 'netlbl_cfg_unlbl_map_add':
netlabel_kapi.c:165:4:
error: implicit declaration of function 'netlbl_af6list_add'
This patch fixes this problem by making the IPv6 specific code conditional
on the IPv6 configuration flags as we done in the rest of NetLabel and the
network stack as a whole. We have to move some variable declarations
around as a result so things may not be quite as pretty, but at least it
builds cleanly now.
Some additional IPv6 conditionals were added to the NetLabel code as well
for the sake of consistency.

The while loop at the bottom of ipoib_mcast_join_finish() will attempt
to send queued multicast packets in mcast->pkt_queue and eventually
end up in ipoib_mcast_send():
if (!mcast->ah) {
if (skb_queue_len(&mcast->pkt_queue) < IPOIB_MAX_MCAST_QUEUE)
skb_queue_tail(&mcast->pkt_queue, skb);
else {
++dev->stats.tx_dropped;
dev_kfree_skb_any(skb);
}
My read is that the code will requeue the packet and return to the
ipoib_mcast_join_finish() while loop and the stage is set for the
"hung" task diagnostic as the while loop never sees a non-NULL ah, and
will do nothing to resolve.
There are GFP_ATOMIC allocates in the provider routines, so this is
possible and should be dealt with.
The test that induced the failure is associated with a host SM on the
same server during a shutdown.
This patch causes ipoib_mcast_join_finish() to exit with an error
which will flush the queued mcast packets. Nothing is done to unwind
the QP attached state so that subsequent sends from above will retry
the join.

sctp: better integer overflow check in sctp_auth_create_key()
The check from commit 30c2235c is incomplete and cannot prevent
cases like key_len = 0x80000000 (INT_MAX + 1). In that case, the
left-hand side of the check (INT_MAX - key_len), which is unsigned,
becomes 0xffffffff (UINT_MAX) and bypasses the check.
However this shouldn't be a security issue. The function is called
from the following two code paths:
1) setsockopt()
2) sctp_auth_asoc_set_secret()
In case (1), sca_keylength is never going to exceed 65535 since it's
bounded by a u16 from the user API. As such, the key length will
never overflow.
In case (2), sca_keylength is computed based on the user key (1 short)
and 2 * key_vector (3 shorts) for a total of 7 * USHRT_MAX, which still
will not overflow.
In other words, this overflow check is not really necessary. Just
make it more correct.

regmap: Allow regmap_update_bits() users to detect changes
Some users of regmap_update_bits() would like to be able to tell their
users if they actually did an update so provide a variant which also
returns a flag indicating if an update took place. We could return a
tristate in the return value of regmap_update_bits() but this makes the
API more cumbersome to use and doesn't fit with the general zero for
success idiom we have.
