drivers/atm/horizon.c has unusually large number
of static inline functions - 36.

[IPv6]: Change IPv6 unspecified destination address to ::1 for raw and un-connected sockets

This patch fixes a difference between IPv4 and IPv6 when sending packets
to the unspecified address (either 0.0.0.0 or ::) when using raw or
un-connected UDP sockets.  There are two cases where IPv6 either fails
to send anything, or sends with the destination address set to ::.  For
example:

--> ping -c1 0.0.0.0
PING 0.0.0.0 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.032 ms

--> ping6 -c1 ::
PING ::(::) 56 data bytes
ping: sendmsg: Invalid argument

Doing a sendto("0.0.0.0") reveals:

10:55:01.495090 IP localhost.32780 > localhost.7639: UDP, length 100

Doing a sendto("::") reveals:

10:56:13.262478 IP6 fe80::217:8ff:fe7d:4718.32779 > ::.7639: UDP, length 100

If you issue a connect() first in the UDP case, it will be sent to ::1,
similar to what happens with TCP.

This restores the BSD-ism.

/* Exit if not found */
.code   = BPF_JMP | BPF_JEQ | BPF_K,
.k = 0,
.jt = <error>
},
...

A nested attribute below the CTA_PROTOINFO attribute would then
be parsed like this:

...
{
/* A += sizeof(struct nlattr) */
.code = BPF_ALU | BPF_ADD | BPF_K,

[IPV4]: Fix byte value boundary check in do_ip_getsockopt().

This fixes kernel bugzilla 10371.

As reported by M.Piechaczek@osmosys.tv, if we try to grab a
char sized socket option value, as in:

  unsigned char ttl = 255;
  socklen_t     len = sizeof(ttl);

  getsockopt(socket, IPPROTO_IP, IP_MULTICAST_TTL, &ttl, &len);

The ttl returned will be wrong on big-endian, and on both little-
endian and big-endian the next three bytes in userspace are written
with garbage.

It's because of this test in do_ip_getsockopt():

if (len < sizeof(int) && len > 0 && val>=0 && val<255) {

It should allow a 'val' of 255 to pass here, but it doesn't so it
copies a full 'int' back to userspace.

On little-endian that will write the correct value into the location
but it spams on the next three bytes in userspace.  On big endian it
writes the wrong value into the location and spams the next three
bytes.

mac80211: fix key vs. sta locking problems

Up to now, key manipulation is supposed to run under RTNL to
avoid concurrent manipulations and also allow the set_key()
hardware callback to sleep. This is not feasible because STA
structs are rcu-protected and thus a lot of operations there
cannot take the RTNL. Also, key references are rcu-protected
so we cannot do things atomically.

This patch changes key locking completely:
 * key operations are now atomic
 * hardware crypto offload is enabled and disabled from
   a workqueue, due to that key freeing is also delayed
 * debugfs code is also run from a workqueue
 * keys reference STAs (and vice versa!) so during STA
   unlink the STAs key reference is removed but not the
   keys STA reference, to avoid races key todo work is
   run before STA destruction.
 * fewer STA operations now need the RTNL which was
   required due to key operations

This fixes the locking problems lockdep pointed out and also
makes things more light-weight because the rtnl isn't required
as much.

Note that the key todo lock/key mutex are global locks, this
is not required, of course, they could be per-hardware instead.
