Al Viro spotted a bogus use of u64 on the input sequence number which
is big-endian. This patch fixes it by giving the input sequence number
its own member in the xfrm_skb_cb structure.

o Outbound sequence number overflow error status
is counted as XfrmOutStateSeqError.
o Additionaly, it changes inbound sequence number replay
error name from XfrmInSeqOutOfWindow to XfrmInStateSeqError
to apply name scheme above.
o Inbound IPv4 UDP encapsuling type mismatch error is wrongly
mapped to XfrmInStateInvalid then this patch fiex the error
to XfrmInStateMismatch.

This patch adds a number of new IPsec audit events to meet the auditing
requirements of RFC4303. This includes audit hooks for the following events:
* Could not find a valid SA [sections 2.1, 3.4.2]
. xfrm_audit_state_notfound()
. xfrm_audit_state_notfound_simple()
* Sequence number overflow [section 3.3.3]
. xfrm_audit_state_replay_overflow()
* Replayed packet [section 3.4.3]
. xfrm_audit_state_replay()
* Integrity check failure [sections 3.4.4.1, 3.4.4.2]
. xfrm_audit_state_icvfail()
While RFC4304 deals only with ESP most of the changes in this patch apply to
IPsec in general, i.e. both AH and ESP. The one case, integrity check
failure, where ESP specific code had to be modified the same was done to the
AH code for the sake of consistency.

This patch adds the xfrm_input_state helper function which returns the
current xfrm state being processed on the input path given an sk_buff.
This is currently only used by xfrm_input but will be used by ESP upon
asynchronous resumption.

When merging the input paths of IPsec I accidentally left a hard-coded
AF_INET for the state lookup call. This broke IPv6 obviously. This
patch fixes by getting the input callers to specify the family through
skb->cb.
Credit goes to Kazunori Miyazawa for diagnosing this and providing an
initial patch.

This patch adds support for async resumptions on input. To do so, the
transform would return -EINPROGRESS and subsequently invoke the
function xfrm_input_resume to resume processing.

The nhoff field isn't actually necessary in xfrm_input. For tunnel
mode transforms we now throw away the output IP header so it makes no
sense to fill in the nexthdr field. For transport mode we can now let
the function transport_finish do the setting and it knows where the
nexthdr field is.
The only other thing that needs the nexthdr field to be set is the
header extraction code. However, we can simply move the protocol
extraction out of the generic header extraction.
We want to minimise the amount of info we have to carry around between
transforms as this simplifies the resumption process for async crypto.

This patch releases the lock on the state before calling
x->type->input. It also adds the lock to the spots where they're
currently needed.
Most of those places (all except mip6) are expected to disappear with
async crypto.

Similar to the moving out of the replay processing on the output, this
patch moves the integrity stat collectin from x->type->input into
xfrm_input.
This would eventually allow transforms such as AH/ESP to be lockless.
The error value EBADMSG (currently unused in the crypto layer) is used
to indicate a failed integrity check. In future this error can be
directly returned by the crypto layer once we switch to aead
algorithms.

As it is xfrm_input first collects a list of xfrm states on the stack
before storing them in the packet's security path just before it
returns. For async crypto, this construction presents an obstacle
since we may need to leave the loop after each transform.
In fact, it's much easier to just skip the stack completely and always
store to the security path. This is proven by the fact that this
patch actually shrinks the code.

As part of the work on asynchronous cryptographic operations, we need
to be able to resume from the spot where they occur. As such, it
helps if we isolate them to one spot.
This patch moves most of the remaining family-specific processing into
the common input code.

With inter-family transforms the inner mode differs from the outer
mode. Attempting to handle both sides from the same function means
that it needs to handle both IPv4 and IPv6 which creates duplication
and confusion.
This patch separates the two parts on the input path so that each
function deals with one family only.
In particular, the functions xfrm4_extract_inut/xfrm6_extract_inut
moves the pertinent fields from the IPv4/IPv6 IP headers into a
neutral format stored in skb->cb. This is then used by the inner mode
input functions to modify the inner IP header. In this way the input
function no longer has to know about the outer address family.

Currently xfrm_parse_spi requires there to be 16 bytes for AH and ESP.
In contrived cases there may not actually be 16 bytes there since the
respective header sizes are less than that (8 and 12 currently).
This patch changes the test to use the actual header length instead of 16.

Slab destructors were no longer supported after Christoph's
c59def9f222d44bb7e2f0a559f2906191a0862d7 change. They've been
BUGs for both slab and slub, and slob never supported them
either.
This rips out support for the dtor pointer from kmem_cache_create()
completely and fixes up every single callsite in the kernel (there were
about 224, not including the slab allocator definitions themselves,
or the documentation references).

For the places where we need a pointer to the transport header, it is
still legal to touch skb->h.raw directly if just adding to,
subtracting from or setting it to another layer header.

Replace all uses of kmem_cache_t with struct kmem_cache.
The patch was generated using the following script:
#!/bin/sh
#
# Replace one string by another in all the kernel sources.
#
set -e
for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do
quilt add $file
sed -e "1,\$s/$1/$2/g" $file >/tmp/$$
mv /tmp/$$ $file
quilt refresh
done
The script was run like this
sh replace kmem_cache_t "struct kmem_cache"

This patch puts mostly read only data in the right section
(read_mostly), to help sharing of these data between CPUS without
memory ping pongs.
On one of my production machine, tcp_statistics was sitting in a
heavily modified cache line, so *every* SNMP update had to force a
reload.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
