Vlad Yasevich e533ca16f3 [SCTP]: Force update of the rto when processing HB-ACK
When processing a HEARTBEAT-ACK it's possible that the transport rto
timers will not be updated because a prior T3-RTX processing would
have cleared the rto_pending flag on the transport.  However, if
we received a valid HEARTBEAT-ACK, we want to force update the
rto variables, so re-set the rto_pending flag before calling
sctp_transport_update_rto().

David S. Miller e89862f4c5 [TCP]: Restore SKB socket owner setting in tcp_transmit_skb().
Revert 931731123a

We can't elide the skb_set_owner_w() here because things like certain
netfilter targets (such as owner MATCH) need a socket to be set on the
SKB for correct operation.

Thanks to Jan Engelhardt and other netfilter list members for
pointing this out.

Vlad Yasevich 732ba35e75 [SCTP]: Fix SACK sequence during shutdown
Currently, when association enters SHUTDOWN state,the
implementation will SACK any DATA first and then transmit
the SHUTDOWN chunk.  This is against the order required by
2960bis spec.  SHUTDOWN must always be first, followed by
SACK. This change forces this order and also enables bundling.

Sridhar Samudrala 29c7cf9618 [SCTP]: Handle address add/delete events in a more efficient way.
Currently in SCTP, we maintain a local address list by rebuilding the whole
list from the device list whenever we get a address add/delete event.

This patch fixes it by only adding/deleting the address for which we
receive the event.

Also removed the sctp_local_addr_lock() which is no longer needed as we
now use list_for_each_safe() to traverse this list. This fixes the bugs
in sctp_copy_laddrs_xxx() routines where we do copy_to_user() while
holding this lock.

Christoph Lameter e18b890bb0 [PATCH] slab: remove kmem_cache_t
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"
