The AES setkey routine writes 64 bytes to the E_KEY area even though
there are only 60 bytes there. It is in fact safe since E_KEY is
immediately follwed by D_KEY which is initialised afterwards. However,
doing this may trigger undefined behaviour and makes Coverity unhappy.
So by combining E_KEY and D_KEY into one array we sidestep this issue
altogether.
This problem was reported by Adrian Bunk.

Since tfm contexts can contain arbitrary types we should provide at least
natural alignment (__attribute__ ((__aligned__))) for them. In particular,
this is needed on the Xscale which is a 32-bit architecture with a u64 type
that requires 64-bit alignment. This problem was reported by Ronen Shitrit.
The crypto_tfm structure's size was 44 bytes on 32-bit architectures and
80 bytes on 64-bit architectures. So adding this requirement only means
that we have to add an extra 4 bytes on 32-bit architectures.
On i386 the natural alignment is 16 bytes which also benefits the VIA
Padlock as it no longer has to manually align its context structure to
128 bits.

Here are some possible (and trivial) cleanups.
- use kzalloc() where possible
- invert allocation failure test like

/* Rest of function here */
}
to
if (object == NULL)
return NULL;
/* Rest of function here */

Bridge's communicate with each other using Spanning Tree Protocol
over a standard multicast address. There are times when testing or
layering bridges over existing topologies or tunnels, when it is
useful to use alternative multicast addresses for STP packets.
The 802.1d standard has some unused addresses, that can be used for this.
This patch is restrictive in that it only allows one of the possible
addresses in the standard.

Use LLC for the receive path of Spanning Tree Protocol packets.
This allows link local multicast packets to be received by
other protocols (if they care), and uses the existing LLC
code to get STP packets back into bridge code.
The bridge multicast address is also checked, so bridges using
other link local multicast addresses are ignored. This allows
for use of different multicast addresses to define separate STP
domains.

This will later be included in struct dccp_request_sock so that we can
have per connection feature negotiation state while in the 3way
handshake, when we clone the DCCP_ROLE_LISTEN socket (in
dccp_create_openreq_child) we'll just copy this state from
dreq_minisock to dccps_minisock.
Also the feature negotiation and option parsing code will mostly touch
dccps_minisock, which will simplify some stuff.

We're now starting to have quite a number of places that do skb_pull
followed immediately by an skb_postpull_rcsum. We can merge these two
operations into one function with skb_pull_rcsum. This makes sense
since most pull operations on receive skb's need to update the
checksum.
I've decided to make this out-of-line since it is fairly big and the
fast path where hardware checksums are enabled need to call
csum_partial anyway.
Since this is a brand new function we get to add an extra check on the
len argument. As it is most callers of skb_pull ignore its return
value which essentially means that there is no check on the len
argument.
