Zach Brown f6596f9d2b [IPv6] reassembly: Always compute hash under the fragment lock.
This closes a race where an ipq6hashfn() caller could get a hash value
and race with the cycling of the random seed.  By the time they got to
the read_lock they'd have a stale hash value and might not find
previous fragments of their datagram.

This matches the previous patch to IPv4.

Ingo Oeser 78c784c47a [IPV6]: Cleanup of net/ipv6/reassambly.c
Two minor cleanups:

1. Using kzalloc() in fraq_alloc_queue()
   saves the memset() in ipv6_frag_create().

2. Invert sense of if-statements to streamline code.
   Inverts the comment, too.

Patrick McHardy 951dbc8ac7 [IPV6]: Move nextheader offset to the IP6CB
Move nextheader offset to the IP6CB to make it possible to pass a
packet to ip6_input_finish multiple times and have it skip already
parsed headers. As a nice side effect this gets rid of the manual
hopopts skipping in ip6_input_finish.

Yasuyuki Kozakai e7c8a41e81 [IPV4,IPV6]: replace handmade list with hlist in IPv{4,6} reassembly
Both of ipq and frag_queue have *next and **prev, and they can be replaced
with hlist. Thanks Arnaldo Carvalho de Melo for the suggestion.

Stephen Hemminger 42ca89c18b [IPV6]: Need to use pskb_trim_rcsum().
Fix pskb_trim usage in ipv6. Only the udp one is really
a bug, other places are just doing equivalent code.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
