ip: ip_ra_control() rcu fix

commit 66018506e15b (ip: Router Alert RCU conversion) introduced RCU
lookups to ip_call_ra_chain(). It missed proper deinit phase :
When ip_ra_control() deletes an ip_ra_chain, it should make sure
ip_call_ra_chain() users can not start to use socket during the rcu
grace period. It should also delay the sock_put() after the grace
period, or we risk a premature socket freeing and corruptions, as
raw sockets are not rcu protected yet.

This delay avoids using expensive atomic_inc_not_zero() in
ip_call_ra_chain().

wl1251: fix ELP_CTRL register reads

Reading the ELP_CTRL register with sdio_readb causes problems because
hardware seems to be performing a write using stuff bits in the request
(those bits contain write data in write request). This indicates that it
actually expects RAW (read after write) type of request, so perform that
when reading ELP_CTRL instead. Also cache last written value so we know
what to write when doing RAW request.

Because of the above it was not possible to wake the chip from ELP power
saving mode, PM had to be disabled to have the driver usable in SDIO
mode. After this patch PM is functional.

For backporting to 2.6.34 or earlier, this patch depends on
6c1f716e8154ee9315534782b9b1eedea0559a24, which adds the

tcp: Fix slowness in read /proc/net/tcp

This patch address a serious performance issue in reading the
TCP sockets table (/proc/net/tcp).

Reading the full table is done by a number of sequential read
operations.  At each read operation, a seek is done to find the
last socket that was previously read.  This seek operation requires
that the sockets in the table need to be counted up to the current
file position, and to count each of these requires taking a lock for
each non-empty bucket.  The whole algorithm is O(n^2).

The fix is to cache the last bucket value, offset within the bucket,
and the file position returned by the last read operation.   On the
next sequential read, the bucket and offset are used to find the
last read socket immediately without needing ot scan the previous
buckets  the table.  This algorithm t read the whole table is O(n).

The improvement offered by this patch is easily show by performing
cat'ing /proc/net/tcp on a machine with a lot of connections.  With
about 182K connections in the table, I see the following:

- Without patch

r8169: fix random mdio_write failures

Some configurations need delay between the "write completed" indication
and new write to work reliably.

Realtek driver seems to use longer delay when polling the "write complete"
bit, so it waits long enough between writes with high probability (but
could probably break too). This patch adds a new udelay to make sure we
wait unconditionally some time after the write complete indication.

This caused a regression with XID 18000000 boards when the board specific

2e955856ff (r8169: phy init for the 8169scd). Some of the configration

iwlwifi: fix wrapping when handling aggregated batches

Fairly complex code in iwlagn_tx_status_reply_tx handle the status reports for
aggregated packet batches sent by the NIC. This code aims to handle the case
where the NIC retransmits failed packets from a previous batch; the status
information for these packets can sometimes be inserted in the middle of a
batch and are actually not in order by sequence number! (I verified this can
happen with printk's in the function.)

The code in question adaptively identifies the "first" frame of the batch,
taking into account that it may not be the one corresponding to the first agg
status report, and also handles the case when the set of sent packets wraps the
256-character entry buffer. It generates the agg->bitmap field of sent packets
which is later compared to the BlockAck response from the receiver to see which
frames of those sent in this batch were ACKed. A small logic error (wrapping by
0xff==255 instead of 0x100==256) was causing the agg->bitmap to be set
incorrectly.

Fix this wrapping code, and add extensive comments to clarify what is going on.

iwlwifi: parse block ack responses correctly

Compressed BlockAck frames store the ACKs/NACKs in a 64-bit bitmap that starts
at the sequence number of the first frame sent in the aggregated batch. Note
that this is a selective ACKnowledgement following selective retransmission;
e.g., if frames 1,4-5 in a batch are ACKed then the next transmission will
include frames 2-3,6-10 (7 frames). In this latter case, the Compressed
BlockAck will not have all meaningful information in the low order bits -- the
semantically meaningful bits of the BA will be 0x1f3 (where the low-order frame
is seq 2).

The driver code originally just looked at the lower (in this case, 7) bits of
the BlockAck. In this case, the lower 7 bits of 0x1f3 => only 5 packets,
maximum, could ever be ACKed. In reality it should be looking at all of the
bits, filtered by those corresponding to packets that were actually sent. This
flaw meant that the number of correctly ACked packets could be significantly
underreported and might result in asynchronous state between TX and RX sides as
well as driver and uCode.

Fix this and also add a shortcut that doesn't require the code to loop through
all 64 bits of the bitmap but rather stops when no higher packets are ACKed.

In my experiments this fix greatly reduces throughput swing, making throughput
stable and high. It is also likely related to some of the stalls observed in
aggregation mode and maybe some of the buffer underruns observed, e.g.,

iwlwifi: reduce memory allocation

Currently, the driver allocates up to 19 skb pointers
for each TFD, of which we have 256 per queue. This
means that for each TX queue, we allocate 19k/38k
(an order 4 or 5 allocation on 32/64 bit respectively)
just for each queue's "txb" array, which contains only
the SKB pointers.

However, due to the way we use these pointers only the
first one can ever be assigned. When the driver was
initially written, the idea was that it could be
passed multiple SKBs for each TFD and attach all
those to implement gather DMA. However, due to
constraints in the userspace API and lack of TCP/IP
level checksumming in the device, this is in fact not
possible. And even if it were, the SKBs would be
chained, and we wouldn't need to keep pointers to
each anyway.

Change this to only keep track of one SKB per TFD,
and thereby reduce memory consumption to just one
pointer per TFD, which is an order 0 allocation per
transmit queue.

that requires s_active is run under priv->mutex.

This ensures that we don't get sysfs request before we finish to request

iwl3945: enable stuck queue detection on 3945

We learn from
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1834 and
https://bugzilla.redhat.com/show_bug.cgi?id=589777
that 3945 can also suffer from a stuck command queue. Enable stuck queue
detection for iwl3945 to enable recovery in this case.

bonding: allow user-controlled output slave selection

v2: changed bonding module version, modified to apply on top of changes
from previous patch in series, and updated documentation to elaborate on
multiqueue awareness that now exists in bonding driver.

This patch give the user the ability to control the output slave for
round-robin and active-backup bonding.  Similar functionality was
discussed in the past, but Jay Vosburgh indicated he would rather see a
feature like this added to existing modes rather than creating a
completely new mode.  Jay's thoughts as well as Neil's input surrounding
some of the issues with the first implementation pushed us toward a
design that relied on the queue_mapping rather than skb marks.
Round-robin and active-backup modes were chosen as the first users of
this slave selection as they seemed like the most logical choices when
considering a multi-switch environment.

Round-robin mode works without any modification, but active-backup does
require inclusion of the first patch in this series and setting
the 'all_slaves_active' flag.  This will allow reception of unicast traffic on
any of the backup interfaces.

This was tested with IPv4-based filters as well as VLAN-based filters
with good results.

More information as well as a configuration example is available in the
patch to Documentation/networking/bonding.txt.

bonding: add all_slaves_active parameter

v2: changed parameter name from 'keep_all' to 'all_slaves_active' and
skipped setting slaves to inactive rather than creating a new flag at
Jay's suggestion.

In an effort to suppress duplicate frames on certain bonding modes
(specifically the modes that do not require additional configuration on
the switch or switches connected to the host), code was added in the
generic receive patch in 2.6.16.  The current behavior works quite well
for most users, but there are some times it would be nice to restore old
functionality and allow all frames to make their way up the stack.

This patch adds support for a new module option and sysfs file called
'all_slaves_active' that will restore pre-2.6.16 functionality if the
user desires.  The default value is '0' and retains existing behavior,
but the user can set it to '1' and allow all frames up if desired.

rps: tcp: fix rps_sock_flow_table table updates

I believe a moderate SYN flood attack can corrupt RFS flow table
(rps_sock_flow_table), making RPS/RFS much less effective.

Even in a normal situation, server handling short lived sessions suffer
from bad steering for the first data packet of a session, if another SYN
packet is received for another session.

We do following action in tcp_v4_rcv() :

sock_rps_save_rxhash(sk, skb->rxhash);

We should _not_ do this if sk is a LISTEN socket, as about each
packet received on a LISTEN socket has a different rxhash than
previous one.
 -> RPS_NO_CPU markers are spread all over rps_sock_flow_table.

Also, it makes sense to protect sk->rxhash field changes with socket
lock (We currently can change it even if user thread owns the lock
and might use rxhash)

This patch moves sock_rps_save_rxhash() to a sock locked section,
and only for non LISTEN sockets.
