73d4f84fd0 [IPv6] IPsec: fix pmtu calculation of esp
It is a simple bug which uses the wrong member.

This bug does not seriously affect ordinary use of IPsec.
But it is important to pass IPv6 ready logo phase-2
conformance test of IPsec SGW.

d4875b049b [IPSEC] Fix block size/MTU bugs in ESP
This patch fixes the following bugs in ESP:

* Fix transport mode MTU overestimate.  This means that the inner MTU
  is smaller than it needs be.  Worse yet, given an input MTU which
  is a multiple of 4 it will always produce an estimate which is not
  a multiple of 4.

  For example, given a standard ESP/3DES/MD5 transform and an MTU of
  1500, the resulting MTU for transport mode is 1462 when it should
  be 1464.

  The reason for this is because IP header lengths are always a multiple
  of 4 for IPv4 and 8 for IPv6.

* Ensure that the block size is at least 4.  This is required by RFC2406
  and corresponds to what the esp_output function does.  At the moment
  this only affects crypto_null as its block size is 1.

573dbd9596 [CRYPTO]: crypto_free_tfm() callers no longer need to check for NULL
Since the patch to add a NULL short-circuit to crypto_free_tfm() went in,
there's no longer any need for callers of that function to check for NULL.
This patch removes the redundant NULL checks and also a few similar checks
for NULL before calls to kfree() that I ran into while doing the
crypto_free_tfm bits.

I've succesfuly compile tested this patch, and a kernel with the patch 
applied boots and runs just fine.

When I posted the patch to LKML (and other lists/people on Cc) it drew the
following comments :

 J. Bruce Fields commented
  "I've no problem with the auth_gss or nfsv4 bits.--b."

 Sridhar Samudrala said
  "sctp change looks fine."

 Herbert Xu signed off on the patch.

So, I guess this is ready to be dropped into -mm and eventually mainline.

72cb6962a9 [IPSEC]: Add xfrm_init_state
This patch adds xfrm_init_state which is simply a wrapper that calls
xfrm_get_type and subsequently x->type->init_state.  It also gets rid
of the unused args argument.

Abstracting it out allows us to add common initialisation code, e.g.,
to set family-specific flags.

The add_time setting in xfrm_user.c was deleted because it's already
set by xfrm_state_alloc.

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!
