There were still a few comments left refering to verify_area, and two
functions, verify_area_skas & verify_area_tt that just wrap corresponding
access_ok_skas & access_ok_tt functions, just like verify_area does for
access_ok - deprecate those.

There was also a few places that still used verify_area in commented-out
code, fix those up to use access_ok.

After applying this one there should not be anything left but finally
removing verify_area completely, which will happen after a kernel release
or two.

In the event a raw socket is created for sending purposes only, the creator
never bothers to check the socket's receive queue.  But we continue to
add skbs to its queue until it fills up.

Unfortunately, if ip_conntrack is loaded on the box, each skb we add to the
queue potentially holds a reference to a conntrack.  If the user attempts
to unload ip_conntrack, we will spin around forever since the queued skbs
are pinned.

Calculate hashtable size to fit into a page instead of a hardcoded
256 buckets hash table. Results in a 1024 buckets hashtable on
most systems.

Replace old naive extract-8-lsb-bits algorithm with a better
algorithm xor'ing 3 or 4 bit fields at the size of the hashtable
array index in order to improve distribution if the majority of
the lower bits are unused while keeping zero collision behaviour
for the most common use case.

Thanks to Wang Jian <lark@linux.net.cn> for bringing this issue

The SELinux hooks invoke ipv6_skip_exthdr() with an incorrect
length final argument.  However, the length argument turns out
to be superfluous.

I was just reading ipv6_skip_exthdr and it occured to me that we can
get rid of len altogether.  The only place where len is used is to
check whether the skb has two bytes for ipv6_opt_hdr.  This check
is done by skb_header_pointer/skb_copy_bits anyway.

Now it might appear that we've made the code slower by deferring
the check to skb_copy_bits.  However, this check should not trigger
in the common case so this is OK.

The problem is that when doing MTU discovery, the too-large segments in
the write queue will be calculated as having a pcount of >1.  When
tcp_write_xmit() is trying to send, tcp_snd_test() fails the cwnd test
when pcount > cwnd.

The segments are eventually transmitted one at a time by keepalive, but
this can take a long time.

This patch checks if TSO is enabled when setting pcount.

The NAT changes in 2.6.11 changed the position where helpers
are called and perform packet mangling. Before 2.6.11, a NAT
helper was called before the packet was NATed and had its
sequence number adjusted. Since 2.6.11, the helpers get packets
with already adjusted sequence numbers.

This breaks sequence number adjustment, adjust_tcp_sequence()
needs the original sequence number to determine whether
a packet was a retransmission and to store it for further
corrections. It can't be reconstructed without more information
than available, so this patch restores the old order by
calling helpers from a new conntrack hook two priorities
below ip_conntrack_confirm() and adjusting the sequence number
from a new NAT hook one priority below ip_conntrack_confirm().
