To be able to use the cached socket reference in the skb during input
processing we add a new set of lookup functions that receive the skb on
their argument list.

qdisc->requeue was planned to universally replace all requeuing code,
but at the top level we never requeue more than one skb, so qdisc->
gso_skb is enough for this. qdisc->requeue would be used on the lower
levels only for one level deep requeuing (like in sch_hfsc) after
finishing all the changes.

Jay Cliburn noticed and diagnosed a bug triggered in
dev_gso_skb_destructor() after last change from qdisc->gso_skb
to qdisc->requeue list. Since gso_segmented skbs can't be queued
to another list this patch brings back qdisc->gso_skb for them.

This protocol provides some connection handling and negotiated
congestion control. Nokia cellular modems use it for bulk transfers.
It provides packet boundaries (hence SOCK_SEQPACKET). Congestion
control is per packet rather per byte, so we do not re-use the
generic socket memory accounting.

RFC3873 defined SCTP_MIB_OUTOFBLUES:
sctpOutOfBlues OBJECT-TYPE
SYNTAX Counter32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of out of the blue packets received by the host.
An out of the blue packet is an SCTP packet correctly formed,
including the proper checksum, but for which the receiver was
unable to identify an appropriate association."
REFERENCE
"Section 8.4 in RFC2960 deals with the Out-Of-The-Blue
(OOTB) packet definition and procedures."
But OOTB packet INIT, INIT-ACK and SHUTDOWN-ACK(COOKIE-WAIT or
COOKIE-ECHOED state) are not counted by SCTP_MIB_OUTOFBLUES.
Case 1(INIT):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
INIT ---------->
<---------- ABORT
Case 2(INIT-ACK):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
INIT-ACK ---------->
<---------- ABORT
Case 3(SHUTDOWN-ACK):
Endpoint A Endpoint B
(CLOSED) (CLOSED)
<---------- INIT
SHUTDOWN-ACK ---------->
<---------- SHUTDOWN-COMPLETE
Case 4(SHUTDOWN-ACK):
Endpoint A Endpoint B
(CLOSED) (COOKIE-ECHOED)
SHUTDOWN-ACK ---------->
<---------- SHUTDOWN-COMPLETE
This patch fixed the problem.

RFC 4960: Section 9.2
The sender of the SHUTDOWN MAY also start an overall guard timer
'T5-shutdown-guard' to bound the overall time for the shutdown
sequence. At the expiration of this timer, the sender SHOULD abort
the association by sending an ABORT chunk. If the 'T5-shutdown-
guard' timer is used, it SHOULD be set to the recommended value of 5
times 'RTO.Max'.
The timer 'T5-shutdown-guard' is used to counter the overall time
for shutdown sequence, and it's start by the sender of the SHUTDOWN.
So timer 'T5-shutdown-guard' should be start when we send the first
SHUTDOWN chunk and enter the SHUTDOWN-SENT state, not start when we
receipt of the SHUTDOWN primitive and enter SHUTDOWN-PENDING state.
If 'T5-shutdown-guard' timer is start at SHUTDOWN-PENDING state, the
association may be ABORT while data is still transmitting.

sctp_is_any() function that is used to check for wildcard addresses
only looks at the address itself to determine the address family.
This function is used in the API to check the address passed in from
the user. If the user simply zerroes out the sockaddr_storage and
pass that in, we'll end up failing. So, let's try harder to determine
the address family by also checking the socket if it's possible.

Chunks placed on the retransmit list are marked as inelegible
for fast retrasnmission. Since missing indications determine
when fast reransmission is done, there is not point in calling
sctp_mark_missing() on the retransmit list since those chunks

Current TCP code relies on the local port of the listening socket
being the same as the destination address of the incoming
connection. Port redirection used by many transparent proxying
techniques obviously breaks this, so we have to store the original
destination port address.
This patch extends struct inet_request_sock and stores the incoming
destination port value there. It also modifies the handshake code to
use that value as the source port when sending reply packets.

Netfilter's ip_route_me_harder() tries to re-route packets either
generated or re-routed by Netfilter. This patch changes
ip_route_me_harder() to handle packets from non-locally-bound sockets

flags when re-doing the routing lookup.

The TCP stack sends out SYN+ACK/ACK/RST reply packets in response to
incoming packets. The non-local source address check on output bites
us again, as replies for transparently redirected traffic won't have a
chance to leave the node.
This patch selectively sets the FLOWI_FLAG_ANYSRC flag when doing the
route lookup for those replies. Transparent replies are enabled if the
listening socket has the transparent socket flag set.

Herbert Xu came up with the idea and the original patch to make
xfrm_state dump list contain also dumpers:
As it is we go to extraordinary lengths to ensure that states
don't go away while dumpers go to sleep. It's much easier if
we just put the dumpers themselves on the list since they can't
go away while they're going.
I've also changed the order of addition on new states to prevent
a never-ending dump.
Timo Teräs improved the patch to apply cleanly to latest tree,
modified iteration code to be more readable by using a common
struct for entries in the list, implemented the same idea for
xfrm_policy dumping and moved the af_key specific "last" entry
caching to af_key.

This patch adds skb_recycle_check(), which can be used by a network
driver after transmitting an skb to check whether this skb can be
recycled as a receive buffer.
skb_recycle_check() checks that the skb is not shared or cloned, and
that it is linear and its head portion large enough (as determined by
the driver) to be recycled as a receive buffer. If these conditions
are met, it does any necessary reference count dropping and cleans
up the skbuff as if it just came from __alloc_skb().

One of the spin-on-condition loops in routine do_dummy_tx always exits before
the condition is satisfied. The hardware might be left in an inconsistent
state that might be the cause of the PHY transmission errors seen by some
users.

* Update registers
* Update SREV values and add some PHY srevs
* Prepare ath5k.h for newer radios etc
Thanks to Atheros 's HAL source we now know for sure how many parts we have
and what their SREV values are. We also have some updates on registers. Prepare
ath5k for some major updates ;-)
My previous mail had 2 more patches following (git log misusage), sorry for double
posting ;-(

According to the newly-released Atheros HAL code, asserting the
TSF reset bit will toggle a hardware internal state, resulting in a
spurious reset on the next chip reset. Whenever we force a TSF bit,
write the bit twice to clear the internal signal.

When CONFIG_MAC80211_MESH=n and CONFIG_MAC80211_NOINLINE=y,
gcc doesn't optimize out a call to ieee80211_rx_h_mesh_fwding,
even if the previous comparison is always false in this case.
This leads to the following errors during modpost:
ERROR: "mpp_path_lookup" [net/mac80211/mac80211.ko] undefined!
ERROR: "mpp_path_add" [net/mac80211/mac80211.ko] undefined!
Fix by removing the possibility of uninlining
ieee80211_rx_h_mesh_fwding rx handler.
