Subject: wireless: report reasonable bitrate for MCS rates through wext

Previously, cfg80211 had reported "0" for MCS (i.e. 802.11n) bitrates
through the wireless extensions interface.  However, nl80211 was
converting MCS rates into a reasonable bitrate number.  This patch moves
the nl80211 code to cfg80211 where it is now shared between both the
nl80211 interface and the wireless extensions interface.

Subject: wireless: hostap, fix oops due to early probing interrupt

BugLink: https://bugs.launchpad.net/ubuntu/+bug/254837

Spurious shared interrupts or early probing interrupts can cause the
hostap interrupt handler to oops before the driver has fully configured
the IO base port addresses. In some cases the oops can be because
the hardware shares an interrupt line, on other cases it is due to a
race condition between probing for the hardware and configuring
the IO base port. The latter occurs because the probing is required to
determin the hardware port address which is only determined when the probe
can interrupt the hardware (catch 22).

This patch catches this pre-configured condition to avoid the oops.

Subject: mac80211: make station management completely depend on vif

The station management currently uses the virtual
interface, but you cannot add the same station to
multiple virtual interfaces if you're communicating
with it in multiple ways.

This restriction should be lifted so that in the
future we can, for instance, support bluetooth 3
with an access point that mac80211 is already
associated to.

We can do that by requiring all sta_info_get users
to provide the virtual interface and making the RX
code aware that an address may match more than one
station struct. Thanks to the previous patches this
one isn't all that large and except for the RX and
TX status paths changes has low complexity.

Subject: mac80211: reduce reliance on netdev

For bluetooth 3, we will most likely not have
a netdev for a virtual interface (sdata), so
prepare for that by reducing the reliance on
having a netdev. This patch moves the name
and address fields into the sdata struct and
uses them from there all over. Some work is
needed to keep them sync'ed, but that's not
a lot of work and in slow paths anyway.

In doing so, this also reduces the number of
pointer dereferences in many places, because
of things like sdata->dev->dev_addr becoming
sdata->vif.addr.

AR9170 has the bad habit of choking when traffic builds up.
Tests have shown that this can partially be attributed to
a huge buildup of backlogged frames.

Time has passed and now they do nothing more than
duplicating txinfo->flags.

This patch aggregates a bunch of small random changes
that won't fit really anywhere else properly.

1. move tid-locating macro into a separate function.

2. remove redundant NULL check.

3. add modulation mask definition

to use the same. Otherwise problems with wakeup might get unnoticed.

Subject: mac80211: remove payload alignment warning

The payload alignment warning enabled by MAC80211_DEBUG_PACKET_ALIGNMENT is
difficult. To fix it, a firmware change is needed but in most cases that's
very difficult. So the benefit from the warning is low and most probably
it just creates more confusion for people who just enable all warnings
(like it did for me).

Remove the unaligned IP payload warning and the kconfig option. But
leave the unaligned packet warning, it will be enabled with
MAC80211_VERBOSE_DEBUG.

Subject: wireless: support internal statically compiled regulatory database

This patch provides infrastructure for machine translation of the
regulatory rules database used by CRDA into a C data structure.
It includes code for searching that database as an alternative
to dynamic regulatory rules updates via CRDA.  Most people should
use CRDA instead of this infrastructure, but it provides a better
alternative than the WIRELESS_OLD_REGULATORY infrastructure (which
can now be removed).

+In most situations the userland solution using CRDA as described
+above is the preferred solution.  However in some cases a set of
+rules built into the kernel itself may be desirable.  To account
+for this situation, a configuration option has been provided
+(i.e. CONFIG_CFG80211_INTERNAL_REGDB).  With this option enabled,
+the wireless database information contained in net/wireless/db.txt is
+used to generate a data structure encoded in net/wireless/regdb.c.
+That option also enables code in net/wireless/reg.c which queries
+the data in regdb.c as an alternative to using CRDA.
+
+The file net/wireless/db.txt should be kept up-to-date with the db.txt
+file available in the git repository here:
+
+    git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-regdb.git
+
+Again, most users in most situations should be using the CRDA package
+provided with their distribution, and in most other situations users
+should be building and using CRDA on their own rather than using
+this option.  If you are not absolutely sure that you should be using
+CONFIG_CFG80211_INTERNAL_REGDB then _DO_NOT_USE_IT_.

Subject: iwlwifi: add continuous uCode event log capability

In order to help uCode debugging, adding the capability to provide
continuous uCode event logging function.

uCode events is located in round-robin event queue and filled by uCode,
by enable continuous event logging, driver check the write pointer
and log the newly added events in iwl_bg_ucode_trace() timer function.

There is still possibility of missing events if event queue being
wrapped before next event dump; but with this capability, we can have
much better understanding of the uCode behavior during runtime; it can
help to debug the uCode related issues.

Methods to enable/disable the continuous event log:
step 1: enable ucode trace timer
     "echo 1 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"
step 2: start ftrace
     sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d
step 3: stop ftrace
     sudo ./trace-cmd report trace.dat
step 4: disable ucode trace timer
     "echo 0 >
/sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing"

use "ucode_tracing" debugfs file to display number of event
queue wrapped when driver attempt the continuous event logging. If event
queue being wrapped more than once when driver has opportunity to log
the event; it indicated there are events missing in the event log trace.

This continuous event log function only available for 4965 and newer
NICs.

Subject: iwlwifi: on-screen event log dump

This feature enables the on-screen uCode event log dump. The original
method will append the event log to syslog; with this capability,
we also enable the user to write script to capture the
events which provide additional flexibility to help uCode debugging

Method
1) change to debugfs directory (sys/kernel/debug/phyX/iwlagn/data)
2) #cat log_event

Subject: iwlwifi: remove extra error msg on sensitivity calibration

Do not need to log error when fail the sensitivity command, driver will send
sensitivity write command to uCode after each sensitivity calibration if
station is associated with AP. It is a normal case when user unload the module
or shutdown the system while still associated with the AP, since uCode already
on the way down, it will not reply the sensitivity write request; report
error in this case will give misleading information, remove the error checking
here to provide a clean shutdown if no other error detected.

For the same issue: remove the skb_trim from the rt2800 fill_rxdone

2. Trim the skb correctly when the L2 padding has been applied.

Also introduce a central macro the compute the L2 padding size.

With the improved L2 padding code, this flag is no longer necessary, as the
rt2x00queue_remove_l2pad is capable of detecting by itself if L2 padding is
applied.
For received frames the RX descriptor flag is still being checked.

Subject: rt2x00: Reorganize L2 padding inserting function.

Simplify the rt2x00queue_insert_l2pad function by handling the alignment
operations one by one. Do not special case special circumstances.
Basically first perform header alignment, and then perform payload alignment
(if any payload does exist). This results in a properly aligned skb.

The end result is better readable code, with better results, as now L2 padding
is inserted only when a payload is actually present in the frame.

RX aggregation is a way to receive multiple 802.11 frames in one RX buffer.
However, we don't know yet how to handle this case in rt2800usb_fill_rxdone
and this has probably no impact on RX performance as well, so we disable it

Subject: rt2x00: Fix rt2800usb RX frame format and as such L2PAD

According to Ralink source code, the RX frame format is RXINFO + RXWI +
802.11 frame + RXD, including various padding. Before this patch, we
were using RXD + RXWI + 802.11 frame, so RXD was not correct.

Doing this, we fix the L2PAD bit which is now correctly set on received
frames.

Subject: mac80211 : fix a race with update_tkip_key

The mac80211 tkip code won't call update_tkip_key, if rx packets
are received without KEY_FLAG_UPLOADED_TO_HARDWARE. This can happen on
first packet because the hardware key stuff is called asynchronously with
todo workqueue.

This patch workaround that by tracking if we sent the key to the driver.

Subject: wireless: add ieee80211_amsdu_to_8023s

Move the A-MSDU handling code from mac80211 to cfg80211 so that more
drivers can use it. The new created function ieee80211_amsdu_to_8023s
converts an A-MSDU frame to a list of 802.3 frames.

Subject: iwmc3200wifi: rx aggregation support

When the device receives an A-MSDU frame (indicated by flag
IWM_RX_TICKET_AMSDU_MSK), use ieee80211_amsdu_to_8023s to convert
it to a list of 802.3 frames and handled them to upper layer.

Subject: mac80211: enable spatial multiplexing powersave

Enable spatial multiplexing in mac80211 by telling the
driver what to do and, where necessary, sending action
frames to the AP to update the requested SMPS mode.

Also includes a trivial implementation for hwsim that
just logs the requested mode.

For now, the userspace interface is in debugfs only,
and let you toggle the requested mode at any time.

Subject: mac80211: allow disabling 40MHz on 2.4GHz

In some situations it is required that a system be
configured with no support for 40 MHz channels in
the 2.4 GHz band. Rather than imposing any such
restrictions on everybody, allow configuration a
system like that with a module parameter. It is
writable at runtime but only takes effect at the
time of the next association.

Subject: cfg80211: avoid sending spurious deauth to userspace

Before
  commit ca9034592823e8179511e48a78731f95bfdd766c
  Author: Holger Schurig <hs4233@mail.mn-solutions.de>
  Date:   Tue Oct 13 13:45:28 2009 +0200

      cfg80211: remove warning in deauth case

we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.

However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",
where "first" means it came to cfg80211 first.

Subject: mac80211: dont try to use existing sta for AP

Clean out some cruft that could use an already existing
sta_info struct -- that case cannot happen. Also, there's
a bug there -- if allocation/insertion fails then it is
possible that we are left in a lingering state where
mac80211 waits for the AP, cfg80211 waits for mac80211,
but the AP has already replied. Since there's no way to
indicate an internal error, pretend there was a timeout,
i.e. that the AP never responded.

Both variables contained the same information (no mesh, old mesh, new mesh).
So we can get rid of one variable.

Also move the mesh-version test from cmd.c into mesh.c.

mesh_autostart_enabled was nowhere set. Rumor is that this is used in the
OLPC tree, but they never did submit their code upstream.

After removing this code, it turned out that the sync_channel stuff is now
also unused, so get rid of that as well.

Subject: libertas: remove priv->capability

This variable was once set to WLAN_CAPABILITY_SHORT_PREAMBLE and
there's no code that could change the variable to something else.
Therefore it seems this is not necessary :-)

Subject: mac80211_hwsim: Check all local addresses for TX Ack status

Since mac80211_hwsim supports multiple virtual interfaces, we need to
iterate through all active interfaces when figuring out whether there
is a match during TX Ack status checking. This fixes TX status
reporting for cases where secondary interfaces are used.

and is just useful for users. To aid debugging add the MCS index back
and an HT20/HT40 mode.

Subject: mac80211: make debugfs mcs set entry reflect 16 bits

The MCS set is 16 bits so when debugging ensure the full 16 bits
are represented. Current reading would make you think its only
8 bits.

When debugging you want to be lazy and not have to parse
bits yourself so let mac80211 debugfs do the parsing for you.

This is what I get against my WRT610N:

Subject: mac80211: only bother printing highest data rate on debugfs if its

IEEE-802.11n spec says the RX highest data rate field does
not specify the highest supported RX data rate if its not set.
Ignore it if not set then. Refer to section 7.3.56.4

Subject: tcp: Remove check in __tcp_push_pending_frames
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

tcp_push checks tcp_send_head and calls __tcp_push_pending_frames,
which again checks tcp_send_head, and this unnecessary check is
done for every other caller of __tcp_push_pending_frames.

Remove tcp_send_head check in __tcp_push_pending_frames and add
the check to tcp_push_pending_frames. Other functions call
__tcp_push_pending_frames only when tcp_send_head would evaluate
to true.

Subject: tcp: Slightly optimize tcp_sendmsg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Slightly optimize tcp_sendmsg since NETIF_F_SG is used many
times iteratively in the loop. The only other modification is
to change:
			} else if (i == MAX_SKB_FRAGS ||
				   (!i &&
				   !(sk->sk_route_caps & NETIF_F_SG))) {
	to:
			} else if (i == MAX_SKB_FRAGS || !sg) {

The reason why this change is correct: this code (other than
the MAX_SKB_FRAGS case) executes only due to the else part
of: "if (skb_tailroom(skb) > 0) {" - i.e. there was no space
in the skb to put the data inline. Hence SG is false is a
sufficient condition, and there is no way a fragment can be
added to the skb.

Changelog:
	- Added the above explanation for the change

Subject: net: Add rtnetlink init_rcvwnd to set the TCP initial receive window

Add rtnetlink init_rcvwnd to set the TCP initial receive window size
advertised by passive and active TCP connections.
The current Linux TCP implementation limits the advertised TCP initial
receive window to the one prescribed by slow start. For short lived
TCP connections used for transaction type of traffic (i.e. http
requests), bounding the advertised TCP initial receive window results
in increased latency to complete the transaction.
Support for setting initial congestion window is already supported
using rtnetlink init_cwnd, but the feature is useless without the
ability to set a larger TCP initial receive window.
The rtnetlink init_rcvwnd allows increasing the TCP initial receive
window, allowing TCP connection to advertise larger TCP receive window
than the ones bounded by slow start.

Subject: enic: Bug fix: use safe queue shutdown in dev->stop

Fix dev->stop shutdown bug where driver was stopping xmit queue and then
disabling intrs.  Fix is to disable intrs first and then stop the xmit
queue, otherwise an interrupt could cause the queue to be rewoken.  Also,
no need to explicitly do queue servicing because queues are cleaned and
reset back to initial state at end of dev->stop.  Servicing queues also
had the side-effect of also rewakening the xmit queue, which is not what
we want.

Subject: enic: Bug fix: try harder to fill Rx ring on skb allocation failures

During dev->open(), make sure we get at least one skb on the Rx ring.
Otherwise abort the interface load.  Also, if we get skb allocation
failures in NAPI poll while trying to replenish the ring, try again
later so we don't end up starving out the Rx ring completely.

Subject: enic: feature add: add ethtool -c/C support

Only rx_usec and tx_usec options for ethtool -C are settable as those
are the only settings that make sense to HW.  Adds driver reporting of
intr coalescing timer value in usec units rather than HW units.

Subject: llc: add support for SO_BINDTODEVICE

Using bind(MAC address) with LLC sockets has O(n) complexity, where n
is the number of interfaces. To overcome this, we add support for
SO_BINDTODEVICE which drops the complexity to O(1).

Subject: llc: convert the socket list to RCU locking

For the reclamation phase we use the SLAB_DESTROY_BY_RCU mechanism,
which require some extra checks in the lookup code:

a) If the current socket was released, reallocated & inserted in
another list it will short circuit the iteration for the current list,
thus we need to restart the lookup.

b) If the current socket was released, reallocated & inserted in the
same list we just need to recheck it matches the look-up criteria and
if not we can skip to the next element.

In this case there is no need to restart the lookup, since sockets are
inserted at the start of the list and the worst that will happen is
that we will iterate throught some of the list elements more then
once.

Note that the /proc and multicast delivery was not yet converted to
RCU, it still uses spinlocks for protection.

Subject: llc: use a device based hash table to speed up multicast delivery

This patch adds a per SAP device based hash table to solve the
multicast delivery scalability issue when we have large number of
interfaces and a large number of sockets bound to the same SAP.

Subject: llc: replace the socket list with a local address based hash

For the cases where a lot of interfaces are used in conjunction with a
lot of LLC sockets bound to the same SAP, the iteration of the socket
list becomes prohibitively expensive.

Replacing the list with a a local address based hash significantly
improves the bind and listener lookup operations as well as the
datagram delivery.

Connected sockets delivery is also improved, but this patch does not
address the case where we have lots of sockets with the same local
address connected to different remote addresses.

In order to keep the socket sanity checks alive and fast a socket
counter was added to the SAP structure.

Subject: llc: fix SAP reference counting w.r.t. socket handling

The SAP ref counter gets decremented twice when deleting a socket,
although for all but the first socket of a SAP the SAP ref counter was
incremented only once.

Whether the firmware we have loaded is AP or STA firmware decides
which receive descriptor format we have to use.  Therefore, move
rx/tx ring initialisation to be after firmware loading.

Subject: mwl8k: fix up AP vs. STA firmware image receive descriptor handling

The receive descriptor ops that are currently marked as being for
8687 only are actually used for all STA firmware images, whereas the
receive descriptor ops marked as 8366 are only used on 8366 when an
AP firmware image is in use.

Rename the receive descriptor ops to reflect this, use the STA ops
unconditionally if the firmware image loaded reported the STA ready
code, and rename the mwl8k_device_info::rxd_ops member to ap_rxd_ops
to indicate that it should only be used if we are running on AP
firmware.

Subject: b43: Allow PIO mode to be selected at module load

If userencounter the "Fatal DMA Problem" with a BCM43XX device, and
still wish to use b43 as the driver, their only option is to rebuild
the kernel with CONFIG_B43_FORCE_PIO. This patch removes this option and
allows PIO mode to be selected with a load-time parameter for the module.
Note that the configuration variable CONFIG_B43_PIO is also removed.

Once the DMA problem with the BCM4312 devices is solved, this patch will
likely be reverted.

Subject: wl1271: use join command with dummy BSSID

When we need to change the channel before association, we have to send a join
command with a valid BSSID.  With this patch we use 0baddeadbeef as the
BSSID.  There are ongoing discussions with TI to get this done in a cleaner
way.

When we go back to idle, we issue a CMD_DISCONNECT to make sure the firmware
stops listening to the channel and cleans things up internally.

Subject: wl1271: remove workaround for disconnection

Now we're using a the idle information coming from mac80211 to decide when to
disconnect.  If we have joined (ie. we're listening to a channel), whenever
the interface goes to idle, we will issue a disconnect command.  So the
workaround to send a disconnect command before joining is not needed anymore.

The wl1271 firmware supports maximun 25.5dBm, so the driver was returning
-EINVALID to anything above that.  This patch uses the channel max_power
option to limit the TX power to 25dBm.

We were not checking the return value from the call to wl1271_cmd_join().
Added a check to make things more reliable.

The call to wl1271_cmd_build_null_data() was missing when we got associated,
this was causing PS to fail.  This patch adds the call and now PS seems to
work.

We were using CONF_TX_RATE_MASK_ALL when calling wl1271_acx_rate_policies()

values are the same, but the latter is just the correct macro to use.

Some debugging tools require the chip to be powered on before they can work.
With these tools, we shouldn't upload the firmware nor boot the firmware
ourselves, so this debufs file is provided.  It always contains the gpio
power setting (0 = off, 1 = on).  To change the power setting, just write 0
or 1 to the file.

Subject: wl1271: use channel 1 when configuring the data path

In the data path configuration, one of the parameters is the channel.  We
have been setting it to wl->channel, which is not correct in this case.  This
channel has nothing to do with the channel we're currently tuned to, since it
is only used for calibration during this phase.  Hardcoded the channel to 1,
according to the reference driver.

to fail powering up properly. This patch implements retry for the chipset boot
sequence, to work around the hardware problem.

Subject: wl1271: Add pre-power-on sleep

This patch adds a short delay before powering on the wl1271. Normally, it is
not needed, but if the wl1271 has been powered off shortly before, for reliable
firmware-booting this small stabilization delay is required.

Subject: wl1271: Remove beacon-loss-ind from PSM entry failure handling

Remove the beacon-loss indication to stack from PSM entry failure handling -
this will cause more problems than it will solve due to the design of the
mac80211.

Subject: wl1271: Add rudimentary ad-hoc support

This patch adds rudimentary a-hoc support for the driver. It will allow
setting up ad-hoc, and for other devices to scan and join. The beacon and probe
response template setting is slightly dirty, and need to be properly
implemented with support from mac80211. Also, the SSID is not configured to the
firmware - the FW will not be able to respond to probe requests autonomously.

Subject: wl1271: Change rates configured for templates

Previously a "firmware chooses" value was used for the rates of all control
message templates set to the firmware. This resulted in a too high rate to be
chosen to transmit those messages. Change this by configuring a fixed low rate
for the templates.

Subject: wl1271: Check vif for NULL when indicating beacon-loss

Because the interface is started and the vif are created and destroyed
separately, there is a slim possibility beacon-loss indications occur while
there is no vif - causing a kernel-oops unless checked.

Add checking for the vif.

-
-Why:	The old regulatory infrastructure has been replaced with a new one
-	which does not require statically defined regulatory domains. We do
-	not want to keep static regulatory domains in the kernel due to the
-	the dynamic nature of regulatory law and localization. We kept around
-	the old static definitions for the regulatory domains of:

Subject: rt2x00: Let rt2800lib check CONFIG_RT2X00_LIB_USB instead of
 CONFIG_RT2800USB

rt2800lib currently checks whether RT2800USB is enabled in the configuration.
Strictly speaking this is not necessary, it only needs to know whether the
generic rt2x00usb library functions are available. Therefore check for

Subject: rt2x00: convert RT2800PCI_PCI and RT2800PCI_SOC Kconfig symbols to
 booleans.

There is no need for Kconfig symbols RT2800PCI_PCI and RT2800PCI_SOC to be
tristates, as they are only used to check whether RT2800 PCI or SOC support
is to be compiled in.

Subject: rt2x00: Cleanup chip handling helper functions.

Let each of them take a struct rt2x00_dev pointer as argument instead of
a mixture of struct rt2x00_chip and struct rt2x00_dev pointers.
Preparation for further clean ups in the rt2x00 chip handling, especially
for rt2800 devices.

Subject: rtl8180: remove priv->mode

It is only checked in add_interface, and there it is easily replaced
with a check of priv->vif.  If that information should become necessary,
it is available in vif->type anyway.

Subject: rtl8187: remove priv->mode

It is checked in add_interface, but there it is easily replaced with
a check of priv->vif.  If that information should become necessary,
it is available in vif->type anyway.

It is also checked in led_turn_on and led_turn_off, where I made the
substitutions as described above.  Of course, these checks seem to
have been incorrect since the driver was using NL80211_IFTYPE_MONITOR
to indicate no interface rather than NL80211_IFTYPE_UNSPECIFIED.
Anyway, I think these checks may be extraneous...?

Subject: mac80211: introduce flush operation

We've long lacked a good confirmation that frames
have really gone out, e.g. before going off-channel
for a scan. Add a flush() operation that drivers
can implement to provide that confirmation, and use
it in a few places:
 * before scanning sends the nullfunc frames
 * after scanning sends the nullfunc frames, if any
 * when going idle, to send any pending frames

Subject: mac80211: let cfg80211 manage auth state

mac80211 currently hangs on to the auth state by
keeping it on the work list. That can lead to
confusing behaviour like rejecting scans while
authenticated to any AP (but not yet associated.)
It also means that it needs to keep track of the
work struct while associated for when it gets
disassociated (or disassociates.)

Change this to free the work struct after the
authentication completed successfully and
allocate a new one for associating, thereby
letting cfg80211 manage the auth state. Another
change necessary for this is to tell cfg80211
about all unicast deauth frames sent to mac80211
since now it can no longer check the auth state,
but that check was racy anyway.

Subject: mac80211: generalise management work a bit

As a first step of generalising management work,
this renames a few things and puts more information
directly into the struct so that auth/assoc need
not access the BSS pointer as often -- in fact it
can be removed from auth completely. Also since the
previous patch made sure a new work item is used
for association, we can make the different data a
union.

From af6b63741cc4e4dfd575d06beb333b11a8a6e0c0 Mon Sep 17 00:00:00 2001

Subject: mac80211: generalise work handling

In order to use auth/assoc for different purposes
other than MLME, it needs to be split up. For other
purposes, a generic work handling (potentially on
another channel) will be useful.

To achieve that, this patch moves much of the MLME
work handling out of mlme into a new work API. The
API can currently handle probing a specific AP,
authentication and association. The MLME previously
handled probe/authentication as one step and will
continue to do so, but they are separate in the new
work handling.

Work items are RCU-managed to be able to check for
existence of an item for a specific frame in the RX
path, but they can be re-used which the MLME right
now will do for its combined probe/auth step.

Subject: mac80211: rewrite a few work messages

The station we're authenticating/associating with
may not always be an AP in the sense that word is
mostly understood, so print only the MAC address
of the peer instead.

Subject: mac80211: refactor association

Refactor the code to reserve an skb of the right size
(instead of hoping 200 bytes are enough forever), and
also put HT IE generation into an own function.

Additionally, put the HT IE before the vendor-specific
WMM IE. This still leaves things not quite ordered
correctly, due to user-specified IEs, add a note about
that for now.

Subject: mac80211: split up and insert custom IEs correctly

Currently, we insert all user-specified IEs before the HT
IE for association, and after the HT IE for probe requests.
For association, that's correct only if the user-specified
IEs are RSN only, incorrect in all other cases including
WPA. Change this to split apart the user-specified IEs in
two places for association: before the HT IE (e.g. RSN),
after the HT IE (generally empty right now I think?) and
after WMM (all other vendor-specific IEs). For probes,
split the IEs in different places to be correct according
to the spec.

Subject: mac80211: proper bss private data handling

cfg80211 offers private data for each BSS struct,
which mac80211 uses. However, mac80211 uses internal
and external (cfg80211) BSS pointers interchangeably
and has a hack to put the cfg80211 bss struct into
the private struct.

Remove this hack, properly converting between the
pointers wherever necessary.

Subject: mac80211: Generalize off-channel operation helpers from scan code

The off-channel operations for going into power save mode (station
mode) or stop beaconing (AP/IBSS) are not limited to scanning. Move
these into a separate file and allow them to be used for other
purposes, too.

Subject: cfg80211: add remain-on-channel command

Add new commands for requesting the driver to remain awake
on a specified channel for the specified amount of time
(and another command to cancel such an operation). This
can be used to implement userspace-controlled off-channel
operations, like Public Action frame exchange on another
channel than the operation channel.

The off-channel operation should behave similarly to scan,
i.e. the local station (if associated) moves into power
save mode to request the AP to buffer frames for it and
then moves to the other channel to allow the off-channel
operation to be completed. The duration parameter can be
used to request enough time to receive a response from
the target station.

Subject: mac80211: support remain-on-channel command

This implements the new remain-on-channel cfg80211
command in mac80211, extending the work interface.

Also change the work purge code to be able to clean
up events properly (pretending they timed out.)

Subject: mac80211: make off-channel work generic

This changes mac80211 to allow being off-channel for
any type of work, not just the 'remain-on-channel'
work. This also helps fast transition to a BSS on a
different channel.

Subject: mac80211: remove struct ieee80211_if_init_conf

All its members (vif, mac_addr, type) are now available
in the vif struct directly, so we can pass that instead
of the conf struct. I generated this patch (except the
mac80211 and header file changes) with this semantic
patch:

@@
identifier conf, fn, hw;

Subject: mac80211: remove requeue from work

There's no need to be requeueing the work struct
since we check for the scan after removing items
due to possible timeouts.

Subject: mac80211: annotate sleeping driver ops

To make it easier to notice cases of calling sleeping ops in atomic context,
annotate driver-ops.h with appropiate might_sleep() calls. At the same time,
also document in mac80211.h the op functions with missing contexts.

mac80211 doesn't seem to use get_tx_stats anywhere currently. Just to be on
the safe side, I documented it to be atomic, but hopefully the op can be
removed in the future.

Compile-tested only.

This allows a bond device to specify an arp_ip_target as a host that is
not on the same vlan as the base bond device and still use arp
validation.  A configuration like this, now works:

Subject: can: Speed up CAN frame receiption by using ml_priv

this patch removes the hlist that contains the CAN receiver filter lists.
It uses the 'midlayer private' pointer ml_priv and links the filters directly
to the CAN netdevice, which allows to omit the walk through the complete CAN
devices hlist for each received CAN frame.

This patch is tested and does not remove any locking.

Subject: can/netlink: add CAN_CTRLMODE_ONE_SHOT

This patch adds the flag CAN_CTRLMODE_ONE_SHOT. It is used as mask
or flag in the "struct can_ctrlmode".

It allows userspace via netlink to set a CAN controller into the special
"one-shot" mode. In this mode, if supported by the CAN controller, it
tries only once to deliver a CAN frame and aborts it if an error
(e.g.: arbitration lost) happens.

Subject: tipc: use kconfig to limit numeric ranges

We can rely on kconfig to limit these numbers,
no need to limit them at compile time/run time.

Users who modify these numbers manually should
be responsible for themself. :)

Subject: netfilter: SNMP NAT: correct the size argument to kzalloc

obj has type struct snmp_object **, not struct snmp_object *.  But indeed
it is not even clear why kmalloc is needed.  The memory is freed by the end
of the function, so the local variable of pointer type should be sufficient.

The semantic patch that makes this change is as follows:

Subject: wl1271: fix timeout in wl1271_top_reg_read

I noticed a timeout bug in

/drivers/net/wireless/wl12xx/wl1271_spi.c

In the current code you cannot tell why you exited
the "poll for data ready" do-while loop if exiting
was done after the last possible loop.

Then timeout==0 regardless of (val & OCP_READY_MASK) or
!(val & OCP_READY_MASK), leading to possible false timeout...

Simple correction could be decreasing timeout after checking
for !(val & OCP_READY_MASK), not before

(Manually converted from email to an actual patch by me. -- JWL)

Subject: IPVS: Allow boot time change of hash size

I was very frustrated about the fact that I have to recompile the kernel
to change the hash size. So, I created this patch.

If IPVS is built-in you can append ip_vs.conn_tab_bits=?? to kernel
command line, or, if you built IPVS as modules, you can add
options ip_vs conn_tab_bits=??.

To keep everything backward compatible, you still can select the size at
compile time, and that will be used as default.

It has been about a year since this patch was originally posted
and subsequently dropped on the basis of insufficient test data.

Mark Bergsma has provided the following test results which seem
to strongly support the need for larger hash table sizes:

We do however run into the same problem with the default setting (212 =
4096 entries), as most of our LVS balancers handle around a million
connections/SLAB entries at any point in time (around 100-150 kpps
load). With only 4096 hash table entries this implies that each entry
consists of a linked list of 256 connections *on average*.

To provide some statistics, I did an oprofile run on an 2.6.31 kernel,
with both the default 4096 table size, and the same kernel recompiled
with IP_VS_CONN_TAB_BITS set to 18 (218 = 262144 entries). I built a
quick test setup with a part of Wikimedia/Wikipedia's live traffic
mirrored by the switch to the test host.

With the default setting, at ~ 120 kpps packet load we saw a typical %si
CPU usage of around 30-35%, and oprofile reported a hot spot in
ip_vs_conn_in_get:

samples  %        image name               app name
symbol name
1719761  42.3741  ip_vs.ko                 ip_vs.ko      ip_vs_conn_in_get
302577    7.4554  bnx2                     bnx2          /bnx2
181984    4.4840  vmlinux                  vmlinux       __ticket_spin_lock
128636    3.1695  vmlinux                  vmlinux       ip_route_input
74345     1.8318  ip_vs.ko                 ip_vs.ko      ip_vs_conn_out_get
68482     1.6874  vmlinux                  vmlinux       mwait_idle

After loading the recompiled kernel with 218 entries, %si CPU usage
dropped in half to around 12-18%, and oprofile looks much healthier,
with only 7% spent in ip_vs_conn_in_get:

samples  %        image name               app name

Subject: iwlwifi: remove linux/utsrelease.h dependency

Commit 250cce26d5d03337aec4ff8405121f026adb4a89 uses UTS_RELEASE
as the the in-tree iwlwifi driver version. However the inclusion
of generated/utsrelease.h makes it a unpleasant behaviour to
recompile the driver everytime when utsrelease.h is updated. In
fact, the driver module is already built with the UTS_RELEASE
information via vermagic of modinfo. Mark the in-tree driver
with the version string "in-tree" to distinguish with those old
out-of-tree drivers.

Fix it by casting the pointers to unsigned long instead. This makes the
compiler happy again.

Compile-tested only.

Subject: mac80211: fix ieee80211_change_mac() to use struct sockaddr

Setting the mac address from user space was buggy. For example, when
executing this command:

ip link set wlan0 address 00:1f:df:88:cd:55

mac80211 used the address 01:00:00:1f:df:88 instead. It was shifted two
bytes.

The reason was that the addr (type of void *) provided to
ieee80211_change_mac() is actually of type struct sockaddr, not just the
mac address array. Also the call to eth_mac_addr() expects the address to
be struct sockaddr.

Subject: mwl8k: handle station database update for AP's sta entry via
 ->sta_notify()

Inserting and removing a hardware station database entry for the AP
when we are in managed mode is currently done in ->bss_info_changed().

To prepare for adding AP mode support, implement the ->sta_notify()
driver method, and let that handle inserting and removing the hardware
station database entry for our AP instead.

Subject: mwl8k: move ->peer_id from mwl8k_vif to mwl8k_sta

For STA firmware, move the per-peer hardware station ID to the
driver-private part of struct ieee80211_sta, where it belongs.

(Since issuing a hardware station database maintenance command sleeps,
we can't hold a reference to the ieee80211_sta * across the command,
and since we won't know the station ID until after the command
completes, we need to re-lookup the sta when the command is done to
write the returned station ID back to its driver-private part.)

Subject: mwl8k: honor peer rate set

When calling SET_RATE, SET_AID, or when creating a station database
entry for our AP, pass in the AP's rate set instead of just blindly
enabling all legacy rates, so as to end up doing the right thing when
talking to 11b-only APs.

Subject: mwl8k: fix changed flags handling in mwl8k_bss_info_changed()

Previously, mwl8k_bss_info_changed() would refuse to do anything if
the 'changed' argument indicated that the association status hadn't
changed.  Fix this up so that it will allow changing things like the
preamble type, the slot time and the CTS-to-self protection method
without having to reassociate.

Subject: mac80211: fix ampdu_action tx_start ssn

The start_seq_num is taken from the station's tid_seq[tid].
This is fine, except tid_seq sequence counter is shifted
by 4 bits to accommodate for frame fragmentation.

Both (iwlagn & ath9k) were unaffected by this minor glitch,
because they don't read the *ssn for the AMPDU_TX_START action.

Subject: sky2: Lock transmit queue while disabling device

netif_device_detach() does not take the tx_lock, so it's possible that
a call to sky2_xmit_frame is still in progress after
netif_device_detach() is complete.

Take netif_tx_lock() to make sure all transmits have stopped while
we're disabling the devices and that no other CPU is still
transmitting a frame after we've disabling the device.

Proposed fix for "sky2 panic under load" reported by Berck E. Nash.

Subject: qlge: Turn on RX header split based on platform.

Using 4-byte aligned headers is problematic for some architectures.
Since qlge uses 4-byte aligned rx buffers we split headers for these
architectures into a separate buffer and then recopy to align on 2-byte boundary.

New handlers are added here to handle:
1) Small frames (<256 bytes) in a single small buffer.  Allocate a new

2) Large frame (>256 bytes) in a page chunk. Allocate an skb, tack it on frags,
post to napi_gro_receive().

Subject: phy: SMSC device Energy Detect power-down mode

SMSC Ethernet Transceivers (LAN88710, LAN8710, LAN8720, LAN8187,
LAN8700, LAN83C185) provide a mechanism to conserve power when
the device is not connected to an active link partner
(Energy Detect Mode).
So this patch enables the Energy Detect power-down mode
for these Transceivers.

Subject: drivers/net/mac8390.c: Checkpatch cleanups

Use #include <linux/ not #include <asm/
Add spaces after arguments
Comment neatening
Make a couple of arrays static const
Align function arguments
Wrap text at 80 columns where reasonable
Cuddle brace else

The id_table field of the struct pci_driver is constant in <linux/pci.h>
so it is worth to make pci_device_id also constant.

The semantic match that finds this kind of pattern is as follows:

This patch fixes up a problem with found with commit
1f3c8804acba841b5573b953f5560d2683d2db0d.  The original change
overloaded null_or_orig, but doing that prevented any packet handlers
that were not tied to a specific device (i.e. ptype->dev == NULL) from
ever receiving any frames.

The null_or_orig variable cannot be overloaded, and must be kept as NULL
to prevent the frame from being ignored by packet handlers designed to
accept frames on any interface.

Subject: net: RFC3069, private VLAN proxy arp support

This is to be used together with switch technologies, like RFC3069,
that where the individual ports are not allowed to communicate with
each other, but they are allowed to talk to the upstream router.  As
described in RFC 3069, it is possible to allow these hosts to
communicate through the upstream router by proxy_arp'ing.

This patch basically allow proxy arp replies back to the same
interface (from which the ARP request/solicitation was received).

Tunable per device via proc "proxy_arp_pvlan":
  /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan

This switch technology is known by different vendor names:
 - In RFC 3069 it is called VLAN Aggregation.
 - Cisco and Allied Telesyn call it Private VLAN.
 - Hewlett-Packard call it Source-Port filtering or port-isolation.
 - Ericsson call it MAC-Forced Forwarding (RFC Draft).

Subject: net: Make it easier to parse /proc/net/dev contents.

The contents of /proc/net/dev is annoying to parse, because
it changes whether there is a space after the "ethX:" or not.
It depends upon the size of the "Receive bytes" counter,
if the number is below 7 digits, then there is whitespaces
else if the number is 8 digits or above there is no space
between the ":" and the number.

This patch changes the output to assure there is always a space
between the ":" and the number.  Given that all existing userspace
application already need to handle the whitespaces, I see
no breakage of existing tools.

Use the %pM kernel extension to display the MAC address.

The only difference in the output is that the MAC address is
shown in the usual colon-separated hex notation.

Subject: stmmac: convert unicast addr list to list_head

This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr.

Note: this patch also removes a debug printk used for displaying the
mac addresses. Indeed, it's is possible to dump the registers with
ethtool.

by invoking the bus_setup. It is defined
for all the platforms that needs this kind of

Subject: stmmac: do not call fix_mac_speed if NULL

On some platforms, fix_mac_speed is used for
configuring some sysconf registers according
to the working speed.
This patch fixes the fix_mac_speed invocation
that cannot be done if it is a NULL pointer.

Subject: stmmac: reorganise class operations.

This patch reorganises the internal stmmac ops structure.
The stmmac_ops has been splitted into other three structures named:
 stmmac_ops
 stmmac_dma_ops
 stmmac_desc_ops

This makes the code more clear and also helps the next work to
make the driver more generic.

From aec7ff278145280c2c78377aeb98feed02c8b636 Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 6 Jan 2010 23:07:18 +0000
Subject: stmmac: move the dma out from the main

This patch moves the dma related functions (interrupt, start, stop etc.)
out from the main driver code. This will help to support new DMA
engines.

Subject: stmmac: rename mac100 as dwmac100 and fix spare coding style

This patch renames the mac100.[ch] as dwmac100.[ch]; this
looks more specific and appropriate for these chip series.
The patch also fixes some spare coding style issues.

From 21d437cc66dcfd0119a4905214fbbe19f3e276dc Mon Sep 17 00:00:00 2001
From: Giuseppe CAVALLARO <peppe.cavallaro@st.com>
Date: Wed, 6 Jan 2010 23:07:20 +0000
Subject: stmmac: rename the gmac as dwmac1000 and split core and dma parts

Use dwmac1000 naming instead of gmac.
The patch also splits the gmac.c file in two new ones:
dwmac1000_core.c and dwmac1000_dma.c.
This could actually help on some architectures where different
DMA engines are used.

Subject: bnx2: Flush the register writes which setup the MSI-X table

The MSI-X table size needs to be properly set before pci_enable_msix()
is called.  But on certain machines, the writes are delayed and the
MSI-X table size is incorrectly read.  By reading the
BNX2_PCI_MSIX_CONTROL register, the writes are flushed and now
ensure that the MSI-X table is set correctly before MSI-X
is enable on the device.

This patch was originally diagnosed and authored by
Kalyan Ram Chintalapati <kalyanc@vmware.com>.

Subject: ep93xx_eth.c general cleanup

General cleanup of the ep93xx_eth driver.

1) Use pr_fmt() to prefix the module name and __func__ to the error
   messages.
2) <linux/io.h> instead of <asm/io.h>
3) <mach/hardware.h> instead of <mach/ep93xx-regs.h> and <mach/platform.h>
4) Move the ep93xx_mdio_read (and ep93xx_mdio_write) function to eliminate
   the function prototype.
5) Change all the printk(<level> messages to pr_<level> and remove the
   __func__ argument.
6) Use platform_get_{resource/irq} to get the platform resources and add
   an error check.
7) Use resource_size() for request_mem_region() and ioremap().
8) Use %pM to print the MAC address at the end of the probe.
9) Use dev->dev_addr not data->dev_addr for the MAC argument because a
   random address could be used if the platform does not supply one.

The message at the end of the probe is left as a printk since it displays
cleaner without the function name that would be displayed with pr_info().

Subject: can: mscan: fix improper return if dlc < 8 in start_xmit function

The start_xmit function of the MSCAN Driver did return improperly if
the CAN dlc check failed (skb not freed and invalid return code). This
patch adds a proper check of the frame lenght and data size and returns
now correctly. The invalid skb packets are dropped silently as suggested
by David Miller in the thread "[RFC] ndo_validate_skb: Let the netdev
check a valid skb content" on the netdev mailing list.

Furthermore, a typo has been fixed.

Subject: can: mscan-mpc5xxx: add support for the MPC512x processor

The main differences compared to the MSCAN on the MPC5200 are:

- More flexibility in choosing the CAN source clock and frequency:

  Three different clock sources can be selected: "ip", "ref" or "sys".
  For the latter two, a clock divider can be defined as well. If the
  clock source is not specified by the device tree, we first try to
  find an optimal CAN source clock based on the system clock. If that
  is not possible, the reference clock will be used.

- The behavior of bus-off recovery is configurable:

  To comply with the usual handling of Socket-CAN bus-off recovery,
  "recovery on request" is selected (instead of automatic recovery).

Note that only MPC5121 Rev. 2 and later is supported.

+In addition to the required compatible-, reg- and interrupt-properties, you can

+
+- fsl,mscan-clock-source : a string describing the clock source. Valid values
+			   are:	"ip" for ip bus clock

+- fsl,mscan-clock-source : a string describing the clock source. Valid values

+				"sys" for system clock
+			   If this property is not present, an optimal CAN
+			   clock source and frequency based on the system
+			   clock will be selected. If this is not possible,
+			   the reference clock will be used.
+
+- fsl,mscan-clock-divider: for the reference and system clock, an additional

Subject: NET: ipv6, remove unnecessary check

Stanse found a potential null dereference in snmp6_unregister_dev.
There is a check for idev being NULL, but it is dereferenced
earlier. But idev cannot be NULL when passed to
snmp6_unregister_dev, so remove the test.

Subject: NET: irda, remove unnecessary checks

Stanse found a potential null dereference in ircomm_tty_close
and ircomm_tty_hangup. There is a check for tty being NULL,
but it is dereferenced earlier. But it is bogus, the tty cannot
be NULL, so remove the !tty checks.

Subject: ixgbevf: Mailbox communication

The 82599 virtual function device and the master 82599 physical function
device implement a mailbox utility for communication between the devices
using some SRAM scratch memory and a doorbell/answering mechanism enabled
via interrupt and/or polling.  This C module and accompanying header
file implement the base functions for use of this feature.

+
+In This Release
+===============
+
+This file describes the ixgbevf Linux* Base Driver for Intel Network
+Connection.
+
+The ixgbevf driver supports 82599-based virtual function devices that can only
+be activated on kernels with CONFIG_PCI_IOV enabled.
+
+The ixgbevf driver supports virtual functions generated by the ixgbe driver
+with a max_vfs value of 1 or greater.
+
+The guest OS loading the ixgbevf driver must support MSI-X interrupts.
+
+VLANs: There is a limit of a total of 32 shared VLANs to 1 or more VFs.
+
+Identifying Your Adapter
+========================
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+    http://support.intel.com/support/network/sb/CS-008441.htm
+
+Known Issues/Troubleshooting
+============================
+
+  Unloading Physical Function (PF) Driver Causes System Reboots When VM is
+  Running and VF is Loaded on the VM
+  ------------------------------------------------------------------------
+  Do not unload the PF driver (ixgbe) while VFs are assigned to guests.
+
+Support

Subject: ixgbe: Mailbox header and code module

The 82599 virtual function device and the master 82599 physical function
device implement a mailbox utility for communication between the devices
using some SRAM scratch memory and a doorbell/answering mechanism enabled
via interrupt and/or polling.  This C module and accompanying header
file implement the base functions for use of this feature.

Subject: ixgbe: Add SR-IOV features to main module

Adds SR-IOV features supported by the 82599 controller to the main driver
module.  If the CONFIG_PCI_IOV kernel option is selected then the SR-IOV
features are enabled.  Use the max_vfs module option to allocate up to 63
virtual functions per physical port.

These functions merely exist to format a buffer and call
nf_nat_mangle_tcp_packet.

Format the buffer and perform the call in nf_nat_ftp instead.

Use %pI4 for the IP address.

Saves ~600 bytes of text

Subject: netfilter: xt_osf: change %pi4 to %pI4

commit 8a27f7c90ffcb791eed7574922b51fb60b08fc89
changed the output style of %pi4 to use fixed
width leading zero IP addresses "001.002.003.004".

It's useful when printing multiple lines of
addresses, but was a change in output style for
some existing uses.

Using %pI4 restores the previous output style.

Subject: tcp: Generalized TTL Security Mechanism

This patch adds the kernel portions needed to implement
RFC 5082 Generalized TTL Security Mechanism (GTSM).
It is a lightweight security measure against forged
packets causing DoS attacks (for BGP).

This is already implemented the same way in BSD kernels.
For the necessary Quagga patch
  http://www.gossamer-threads.com/lists/quagga/dev/17389

Description from Cisco
  http://www.cisco.com/en/US/docs/ios/12_3t/12_3t7/feature/guide/gt_btsh.html

It does add one byte to each socket structure, but I did
a little rearrangement to reuse a hole (on 64 bit), but it
does grow the structure on 32 bit

This should be documented on ip(4) man page and the Glibc in.h
file also needs update.  IPV6_MINHOPLIMIT should also be added
(although BSD doesn't support that).

Only TCP is supported, but could also be added to UDP, DCCP, SCTP
if desired.

To prevent the CAN drivers to operate on invalid socketbuffers the skbs are

Also the netdev stats are consistently using the CAN data length code (dlc)
for [rx|tx]_bytes now.

Subject: ath9k: re-enable ps by default for new single chip families

The newer single chip hardware family of chipsets have not been
experiencing issues with power saving set by default with recent
fixes merged (even into stable). The remaining issues are only
reported with AR5416 and since enabling PS by default can increase
power savings considerably best to take advantage of that feature
as this has been tested properly.

For more details on this issue see the bug report:

http://bugzilla.kernel.org/show_bug.cgi?id=14267

We leave AR5416 with PS disabled by default, that seems to require
some more work.

Subject: nl80211: Add new WIPHY attribute COVERAGE_CLASS

The new attribute NL80211_ATTR_WIPHY_COVERAGE_CLASS sets IEEE 802.11
Coverage Class, which depends on maximum distance of nodes in a
wireless network. It's required for long distance links (more than a few
hundred meters).

The attribute is now ignored by two non-mac80211 drivers, rndis and
iwmc3200wifi, together with WIPHY_PARAM_RETRY_SHORT and
WIPHY_PARAM_RETRY_LONG. If it turns out to be a problem, we could split
set_wiphy_params callback or add new capability bits.

Subject: ath5k: Fix functions for getting/setting slot time

Functions ath5k_hw_get_slot_time and ath5k_hw_set_slot_time were
converting microseconds to clocks only for AR5210, although it's needed
for all supported devices. The conversion was moved outside the
hardware-specific branches.

The original code also limited minimum slot time to 9, while turbo modes
use 6, this was fixed too.

Subject: ath5k: Reimplement clock rate to usec conversion

The original code was correct in 802.11a mode only, 802.11b/g uses
different clock rates. The new code uses values taken from FreeBSD HAL
and should be correct for all modes including turbo modes.

The former rate calculation was used by slope coefficient calculation
function ath5k_hw_write_ofdm_timings. However, this function requires
the 802.11a values even in 802.11g mode. Thus the use of
ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope
coefficient calculation is not related to clock rate at all.

Subject: ath5k: Implement mac80211 callback set_coverage_class

The callback sets slot time as specified in IEEE 802.11-2007 section
17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS
timeouts accordingly. The values are persistent, they are restored after
device reset.

Make addba_resp_timer aware the HT_AGG_STATE_REQ_STOP_BA_MSK mask
so that when ___ieee80211_stop_tx_ba_session() is issued the timer
will quit. Otherwise when suspend happens before the timer expired,
the timer handler will be called immediately after resume and
messes up driver status.

Subject: mac80211: Select lowest rate based on basic rate set in AP mode

If the basic rate set is configured to not include the lowest rate
(e.g., basic rate set = 6, 12, 24 Mbps in IEEE 802.11g mode), the AP
should not send out broadcast frames at 1 Mbps. This type of
configuration can be used to optimize channel usage in cases where
there is no need for backwards compatibility with IEEE 802.11b-only
devices.

In AP mode, mac80211 was unconditionally using the lowest rate for
Beacon frames and similarly, with all rate control algorithms that use
rate_control_send_low(), the lowest rate ended up being used for all
broadcast frames (and all unicast frames that are sent before
association). Change this to take into account the basic rate
configuration in AP mode, i.e., use the lowest rate in the basic rate
set instead of the lowest supported rate when selecting the rate.

From 37eb0b164cf9fa9f70c8500926f5cde7c652f48e Mon Sep 17 00:00:00 2001
From: Jouni Malinen <jouni.malinen@atheros.com>
Date: Wed, 6 Jan 2010 13:09:08 +0200
Subject: cfg80211/mac80211: Use more generic bitrate mask for rate control

Extend struct cfg80211_bitrate_mask to actually use a bitfield mask
instead of just a single fixed or maximum rate index. This change
itself does not modify the behavior (except for debugfs files), but it
prepares cfg80211 and mac80211 for a new nl80211 command for setting
which rates can be used in TX rate control.

Since frames are now going through the rate control algorithm
unconditionally, the internal IEEE80211_TX_INTFL_RCALGO flag can now
be removed. The RC implementations can use the rate_idx_mask value to
optimize their behavior if only a single rate is enabled.

The old max_rate_idx in struct ieee80211_tx_rate_control is maintained
(but commented as deprecated) for backwards compatibility with existing
RC implementations. Once these implementations have been updated to
use the more generic rate_idx_mask, the max_rate_idx value can be
removed.

Subject: nl80211: New command for setting TX rate mask for rate control

Add a new NL80211_CMD_SET_TX_BITRATE_MASK command and related
attributes to provide support for setting TX rate mask for rate
control. This uses the existing cfg80211 set_bitrate_mask operation
that was previously used only with WEXT compat code (SIOCSIWRATE). The
nl80211 command allows more generic configuration of allowed rates as
a mask instead of fixed/max rate.

Subject: rt2x00: RF3052 is a valid RF chipset for USB devices as well.

The RF3052 chipset is now also being integrated onto USB devices, so
allow the RF chipset and don't treat it as PCI/SOC only.

Subject: mac80211: add functions to create PS Poll and Nullfunc templates

Some hardware, for example wl1251 and wl1271, handle the transmission
of power save related frames in hardware, but the driver is responsible
for creating the templates. It's better to create the templates in mac80211,
that way all drivers can benefit from this.

Add two new functions, ieee80211_pspoll_get() and ieee80211_nullfunc_get()
which drivers need to call to get the frame. Drivers are also responsible
for updating the templates after each association.

Also new struct ieee80211_hdr_3addr is added to ieee80211.h to make it
easy to calculate length of the Nullfunc frame.

Subject: mac80211: use Probe Request template when sending a direct scan

As mac80211 now has a separate function for creating Probe Request templates,
better to use it when sending direct Probe Requests to an AP. Only the
bssid needs to be updated in the template before sending it.

Subject: wl1251: cleanup scanning code

The current scanning code wasn't following the preferred style. Move code
related to scan and trigger scan to commans to wl1251_cmd.c. Because
there's now less code in wl1251_hw_scan(), the function can be now
merged with wl1251_op_hw_scan().

proper way is to use the channels array provided by mac80211.

Subject: wl1251: fix sleep related error paths in wl1251_op_bss_info_changed()

In various cases wl1251_op_bss_info_changed() did not call elp_sleep()
after an error was noticed. Fix it by using correct goto label.

The bug was a theoretical one, in practise it doesn't matter because
if commands start returning errors there will be lots of other problems.

Subject: cfg80211: Store IEs from both Beacon and Probe Response frames

Store information elements from Beacon and Probe Response frames in
separate buffers to allow both sets to be made available through
nl80211. This allows user space applications to get access to IEs from
Beacon frames even if we have received Probe Response frames from the
BSS. Previously, the IEs from Probe Response frames would have
overridden the IEs from Beacon frames.

This feature is of somewhat limited use since most protocols include
the same (or extended) information in Probe Response frames. However,
there are couple of exceptions where the IEs from Beacon frames could
be of some use: TIM IE is only included in Beacon frames (and it would
be needed to figure out the DTIM period used in the BSS) and at least
some implementations of Wireless Provisioning Services seem to include
the full IE only in Beacon frames).

The new BSS attribute for scan results is added to allow both the IE
sets to be delivered. This is done in a way that maintains the
previously used behavior for applications that are not aware of the
new NL80211_BSS_BEACON_IES attribute.

Subject: mac80211: fix a few work bugs

Kalle and Lennert reported problems with the new work
code, and at least Kalle's problem I was able to trace
to a missing jiffies initialisation.

I also ran into a problem where occasionally I couldn't
connect, which seems fixed with kicking the work items
after scanning.

Finally, also add some sanity checking code to verify
that we're not adding work items while an interface is
down -- that case could lead to something similar to
what Lennert was seeing.

There still seems to be a race condition that we're
trying to figure out separately.

Subject: cfg80211: process the max power on a country IE

The max power from each country IE triplet was being ignored.
This fix isn't critical as CRDA was always being used for the lower
limit, but we should process it in case the AP still wants to
decrease power output even more for whatever reason.

Subject: cfg80211: Fix country IE parsing for single channel triplets

This enhances the way we parse country IEs to minimize
the number of regulatory rules that we create. It also fixes
our current implementation which treated country IE triplets
with only one channel as one independed regulatory rule even
though adjecent rules were also being provided.

Without this patch APs which send country IE information with
a channel triplet for each individual channel will force cfg80211
to deny HT40 operation as a regulatory rule would have been created
independently for each channel and as such configured only for
20 MHz operation.

Although 802.11n APs which send country IEs triplets in this fassion
are likely rare Benoit reports this against the Ubiquity NanoStation M5,
with Country "FR" and HT40 enabled.

Since we now have a helper which parses the triplets in intermediate
steps we now take care extra care to process padding.

From 285f2ddae03ca207877262f5a9dbd9cddd8b3913 Mon Sep 17 00:00:00 2001
From: Sujith <Sujith.Manoharan@atheros.com>
Date: Fri, 8 Jan 2010 10:36:07 +0530
Subject: ath9k: Cleanup init/deinit routines

The device initialization and termination functions
were messy and convoluted. Introduce helper functions
to clarify init_softc() and simplify things in general.

Subject: mac80211: use nullfunc frames for 4-addr sta detection

To detect incoming 4-addr stations, hostapd needs to receive a 4-addr
data frame from the remote station, so that it can create the AP VLAN
for it. With this patch, the mlme code emits a 4-addr nullfunc frame
immediately after assoc. On the AP side it also drops 4-addr nullfunc
frames to the cooked monitor mode interface, if the interface hasn't
been fully set up to receive 4-addr data frames yet.

Subject: mac80211: allow station updates on ap interfaces for vlan stations

Since the per-vif station changes, sta_info_get on the ap sdata no
longer returns entries for stations on ap vlans. This causes issues
with hostapd, which currently always passes the ap interface name to
nl80211 calls. This patch provides bug compatibility with the earlier
versions until hostapd is fixed.

Subject: mac80211: do not transmit frames on unconfigured 4-addr vlan
 interfaces

If frames are transmitted on 4-addr ap vlan interfaces with no station,
they end up being transmitted unencrypted, even if the ap interface
uses WPA. This patch add some sanity checking to make sure that this
does not happen.

 mwl8k_cmd_set_edca_params()

The comment and code in mwl8k_cmd_set_edca_params() suggest that the
mapping between SET_EDCA_PARAMS queue numbers and transmit rings isn't
actually 1:1, while tests show that the mapping is in fact 1:1.  So,
get rid of the transmit queue 0/1 swapping.

Subject: mwl8k: bump the transmit wait timeout to 5 seconds

While it is reasonable to expect that at least one transmit ring entry
will be processed per second while we are waiting for the transmit
rings to drain, the firmware can end up doing batching of transmit ring
status writeback, which means that the transmit rings can appear stuck
for more than a second at a time.

Bump the TX drain wait timeout up from 1 to 5 seconds to account for
this.

at it, rename it to *_sta, as this is the STA version of the command.

Subject: mwl8k: keep TX_DONE interrupt masked while transmit reclaim is
 running

By making use of the CLEAR_SEL feature of the mwl8k host interface
interrupt controller, we can keep the TX_DONE interrupt source masked
while the transmit reclaim tasklet is running (NAPI style) without
having to touch the interrupt controller's interrupt mask register
when entering or exiting polling mode, and without having to do any
more register reads/writes than we do now.

When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading
the interrupt status register will clear the TX_DONE status bit if
it was set, allowing it to be set again if a new TX_DONE event arrives
while we are running the TX reclaim tasklet, but such a new event will
then not trigger another PCI interrupt until a zero is written to the
TX_DONE interrupt status register bit.

I.e., if we write a zero to the TX_DONE interrupt source bit in the
interrupt status register when the TX reclaim tasklet thinks it's
done, a PCI interrupt will be triggered if a new TX_DONE event arrived
from the hardware between us deciding that there is no more work to do
and re-enabling the TX_DONE interrupt source, thereby avoiding the
classic NAPI poll mode exit race that would otherwise occur.

Subject: mwl8k: move receive processing to tasklet

Like how TX reclaim is done in a tasklet, move receive processing
to tasklet context as well.  This can have nice benefits for CPU
utilisation and throughput, especially at 3-stream rates.

(Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to
avoid having to touch the interrupt mask registers.)

just iwlwifi driver do not need to take any action for it; so instead of
return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP"
to make sure mac80211 will not get wrong impression.

Subject: mac80211: flush workqueue before calling driver ->stop() method

Since commit "mwl8k: handle station database update for AP's sta entry
via ->sta_notify()", mwl8k every now and then gets a command timeout
when ifconfig'ing a STA interface down.  This turns out to be due to
mwl8k_stop() being called while the work queue item that was scheduled
by mwl8k_sta_notify() to remove the STA entry for the associated AP is
still queued, and the former disables interrupts so that when the
latter eventually runs, a command completion interrupt is never seen.

Fix this by changing ieee80211_stop_device() so that the workqueue is
flushed before drv_stop() is called, instead of doing it the other way
around as is done now.  (As ->stop() is allowed to sleep, there isn't
any reason for drivers to queue work from within it.)

Subject: mac80211: add U-APSD client support

Add Unscheduled Automatic Power-Save Delivery (U-APSD) client support. The
idea is that the data frames from the client trigger AP to send the buffered
frames with ACs which have U-APSD enabled. This decreases latency and makes it
possible to save even more power.

Driver needs to use IEEE80211_HW_UAPSD to enable the feature. The current
implementation assumes that firmware takes care of the wakeup and
hardware needing IEEE80211_HW_PS_NULLFUNC_STACK is not yet supported.

Tested with wl1251 on a Nokia N900 and Cisco Aironet 1231G AP and running
various test traffic with ping.

Subject: mac80211: create tx handler for dynamic ps

Currently dynamic ps check is in ieee80211_xmit(), but it's cleaner
to have a separate tx handler for this. Also this is a prerequisite for
U-APSD client mode which needs to know the queue frame is in.

Also need_dynamic_ps() function is embedded to the tx handler.

No functional changes expect that the code is run in a later phase than
originally.

Subject: mac80211: check uapsd state for dynamic power save

To make U-APSD client mode effective, we must not wake up from dynamic power
save when transmitting frames. So if dynamic power save is enabled, it needs
check the queue the transmitted packet is in and decide if we need to wake
up or not.

In a perfect world, where all packets would have correct QoS tags, U-APSD
enabled queues should not trigger wakeup from power save. But in the real
world, where very few packets have correct QoS tags, this won't work. For
example, if only voip class has U-APSD enabled and we send a packet in voip
class, but the packets we receive are in best effort class, we would receive
the packets with the legacy power save method. And that would increase
latencies too much from a voip application point of view.

The workaround is to enable U-APSD for all qeueus and still use dynamic ps
wakeup for all other queues except voip. That way we can still save power
with a voip application and not sacrifice latency. Normal traffic (in
background, best effort or video class) would still trigger wakeup from
dynamic power save.

Subject: mwl8k: properly set receive status rate index on 5 GHz receive

The mwl8k firmware uses indices into the 2.4 GHz band rate table for
the receive descriptor channel field even if the packet was received
on a 5 GHz channel, while mac80211 expects an index into the 5 GHz
band rate table when packets are received on the 5 GHz band, which
presents a mismatch as the 5 GHz band rate table lacks the five
non-OFDM rates that the 2.4 GHz rate table starts with.

To handle this properly, we need to substract 5 from the rate index
field if the packet was received on a 5 GHz channel (and was not
received at an MCS rate).

Subject: mwl8k: handle 5 GHz legacy rate bitmaps in firmware commands

Whenever mac80211 gives us a legacy rate bitmap in the context of the
5 GHz band, we need to remember to shift the bitmap left by 5 positions
before giving it to the firmware, as the firmware follows the bitmap
bit assignment of the 2.4 GHz rate table even if we're on the 5 GHz
band, and the 2.4 GHz rate table includes five non-OFDM rates at the
start that are not valid in the 5 GHz band.

Subject: mwl8k: use firmware capability field to decide which bands to
 register

Make the decision about whether to register the 2.4 and 5 GHz bands
with mac80211 by looking at the capability field in GET_HW_SPEC (STA
firmware only for now).  This enables 5 GHz STA operation.

Subject: mwl8k: prepare for posting per-vif firmware commands

One of the bytes in the mwl8k firmware command header is the 'macid'
byte, which for per-vif commands indicates which of the BSSes this
command is intended for.  (For commands that are not per-vif commands,
this byte can just be 0.)

This patch adds mwl8k_post_pervif_cmd(), which will take the macid
assigned to this interface (to be done in ->add_interface()), copy it
into the command packet macid field, and post the command as usual.

Subject: mwl8k: post per-vif firmware commands as per-vif commands

SET_BEACON, SET_MAC_ADDR, BSS_START and SET_NEW_STN are the currently
supported firmware commands that are actually per-vif commands.  Use
mwl8k_post_pervif_cmd() for these commands, so that the macid of the
vif they operate on gets passed down into the firmware.

Subject: mwl8k: enable multi-BSS AP operation

As follows:
- GET_HW_SPEC is now responsible for setting
  priv->{ap,sta}_macids_supported, which are bitmasks of supported
  macids for AP and STA mode.  (Typically, STA firmware images will
  support only one macid, #0, in STA mode, and AP firmware images
  will support macids #0-7, in AP mode.)
- Our wiphy ->interfaces_modes is now set based on the non-zero-ness
  of these two bitmasks.
- We main priv->macids_used, a bitmask of which macids are currently
  in use.  ->add_interface() will assign the lowest free macid for
  this interface type as it is created, or bail out if there are no
  more free macids to assign.  ->delete_interface() will mark the
  macid as being free again.

This enables the multi-BSS code added in the previous commits.

Subject: e1000e: use alternate MAC address on ESB2 if available

Similar to 82571/2/3 parts that already do this, if ESB2/80003es2lan parts
have an alternate MAC address provided in the EEPROM use it instead of the
default MAC address.  This patch makes the the actual code that does this
generic so that it can be better used by both MAC families.

From f4d2dd4cd4d001f5dc20fc76c780c0c20c000c23 Mon Sep 17 00:00:00 2001
From: Bruce Allan <bruce.w.allan@intel.com>
Date: Wed, 13 Jan 2010 02:05:18 +0000
Subject: e1000e: provide MAC-family-specific function to set LAN ID

Provide MAC-specific function pointer to determine the LAN ID (PCI func).
The LAN ID is used internally by the driver to determine which h/w lock
to use to protect accessing the PHY on ESB2 as well as help to determine
the alternate MAC address on some parts.

enforce the requirement to update the entire multicast table array all at
once instead of piecemeal which causes problems on some parts.

Subject: qeth: avoid recovery during device online setting

If a qeth device is set online, several initialisation steps are
performed. If a failure in one of these steps occurs, the qeth
device is reset into DOWN state. If due to the failure a qeth recovery
is scheduled and started in another thread, this might cause all kinds
of conflicts, even a kernel panic. The patch forbids scheduling of a
qeth recovery while online processing is performed till the card is in
state SOFTSETUP.

Subject: proc_fops: convert drivers/isdn/ to seq_file

Convert code away from ->read_proc/->write_proc interfaces.  Switch to
proc_create()/proc_create_data() which make addition of proc entries
reliable wrt NULL ->proc_fops, NULL ->data and so on.

Problem with ->read_proc et al is described here commit
786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in
/proc entries"

Ah, you are right. I took '%' for '&'. John, would you revert it? Sorry
for the false alarm.

Subject: cfg80211: fix 2 GHz subband calculation for country IEs

Country IEs triplets are getting an extra channel with
the current count. This does not affect regulatory because
we always took the intersection between what the AP gave
and what CRDA believed is correct.

This however does fix processing some Country IEs with multiple
sequential 2 GHz triplets. Since our parser and the spec mandates
all channels be monitonically increasing we would drop the IE after
noticing the second triplet begins on a channel already processed.
APs that send these type of country IEs seems rare though.

Subject: Remove config option B43_LEGACY_RFKILL completely

In f41f3f373dd72344c65d801d6381fe83ef3a2c54 the B43 driver was ported
to use the cfg80211 API for rfkill and consequently the config option
was dropped (RFKILL is now unconditionally enabled).

However in the Kernel Info the feature is still checked and reported
missing. This patch just removes the conditional and the relevant code
blocks while still reporting that feature unconditionally would be
another option (it's always there).

Subject: ath9k: Fix panic on driver load

The device has to be marked as invalid before
registering the ISR. HW initialization takes place
after the ISR has been registered, and the invalid
flag is eventually cleared in the ->stop() callback.

Subject: net/core/sock.c: quiet sparse noise

In sock_getsockopt the symbol 'lv' is declared as an
unsigned int type, probably due to sizeof returning a
size_t which is really an unsigned int.

This produces a sparse warning for SO_PEERNAME due to
the sock->ops->getname() call:

warning: incorrect type in argument 3 (different signedness)
   expected int *sockaddr_len
   got unsigned int *<noident>

Quiet the warning by changing the type of 'lv' to an int.

Subject: ipv4: Use less conflicting local var name in change_nexthops() loop
 macro.

As noticed by H Hartley Sweeten, since change_nexthops() uses 'nh'
as it's iterator variable, it can conflict with other existing
local vars.

Use "nexthop_nh" to avoid the conflict and make it easier to figure
out where this magic variable comes from.

From 05c2828c72c4eabf62376adfe27bd24797621f62 Mon Sep 17 00:00:00 2001
From: "Michael S. Tsirkin" <mst@redhat.com>
Date: Thu, 14 Jan 2010 06:17:09 +0000
Subject: tun: export underlying socket

Tun device looks similar to a packet socket
in that both pass complete frames from/to userspace.

This patch fills in enough fields in the socket underlying tun driver
to support sendmsg/recvmsg operations, and message flags
MSG_TRUNC and MSG_DONTWAIT, and exports access to this socket
to modules.  Regular read/write behaviour is unchanged.

This way, code using raw sockets to inject packets
into a physical device, can support injecting
packets into host network stack almost without modification.

First user of this interface will be vhost virtualization
accelerator.

Subject: mm: export use_mm/unuse_mm to modules

vhost net module wants to do copy to/from user from a kernel thread,
which needs use_mm. Export it to modules.

Subject: vhost_net: a kernel-level virtio server

What it is: vhost net is a character device that can be used to reduce
the number of system calls involved in virtio networking.
Existing virtio net code is used in the guest without modification.

There's similarity with vringfd, with some differences and reduced scope
- uses eventfd for signalling
- structures can be moved around in memory at any time (good for
  migration, bug work-arounds in userspace)
- write logging is supported (good for migration)
- support memory table and not just an offset (needed for kvm)

common virtio related code has been put in a separate file vhost.c and
can be made into a separate module if/when more backends appear.  I used
Rusty's lguest.c as the source for developing this part : this supplied
me with witty comments I wouldn't be able to write myself.

What it is not: vhost net is not a bus, and not a generic new system
call. No assumptions are made on how guest performs hypercalls.
Userspace hypervisors are supported as well as kvm.

How it works: Basically, we connect virtio frontend (configured by
userspace) to a backend. The backend could be a network device, or a tap
device.  Backend is also configured by userspace, including vlan/mac
etc.

Status: This works for me, and I haven't see any crashes.
Compared to userspace, people reported improved latency (as I save up to
4 system calls per packet), as well as better bandwidth and CPU
utilization.

Features that I plan to look at in the future:
- mergeable buffers
- zero copy
- scalability tuning: figure out the best threading model to use

Note on RCU usage (this is also documented in vhost.h, near
private_pointer which is the value protected by this variant of RCU):
what is happening is that the rcu_dereference() is being used in a
workqueue item.  The role of rcu_read_lock() is taken on by the start of
execution of the workqueue item, of rcu_read_unlock() by the end of
execution of the workqueue item, and of synchronize_rcu() by
flush_workqueue()/flush_work(). In the future we might need to apply
some gcc attribute or sparse annotation to the function passed to
INIT_WORK(). Paul's ack below is for this RCU usage.

When ieee80211_offchannel_return is called, it needs to re-enabled TX
queues that have been stopped in ieee80211_offchannel_stop_beaconing or
ieee80211_offchannel_stop_station. It happens if we are doing a scan with an
IBSS interface. In this case, the interface stopped transmitting.

Subject: cfg80211: make regulatory_hint_11d() band specific

In practice APs do not send country IE channel triplets for channels
the AP is not operating on and if they were to do so they would have
to use the regulatory extension which we currently do not process.
No AP has been seen in practice that does this though so just drop
those country IEs.

Additionally it has been noted the first series of country IE
channels triplets are specific to the band the AP sends. Propagate
the band on which the country IE was found on reject the country
IE then if the triplets are ever oustide of the band.

Although we now won't process country IE information with multiple
band information we leave the intersection work as is as it is
technically possible for someone to want to eventually process these
type of country IEs with regulatory extensions.

Subject: mac80211: force use_short_slot=true for 5GHz

Normally 5GHz does not have a concept of long vs short slot time,
however the slot time that it ends up using is the same as for 2.4 GHZ
and use_short_slot == true
Because of that, it makes more sense to force use_short_slot = true
whenever 5 GHz is being used, so that this particular check does not
have to be in every single driver that uses this flag.

Subject: ath9k: cleanup slot time and ack/cts timeout handling

Previously ath9k left the initialization of slot timing and ACK/CTS
timeout to the mode specific initvals. This does not handle short vs
long slot in 2.4 GHz and uses a rather strange value for the 2.4 GHz
ACK timeout (64 usec).
This patch uses the proper ath9k_hw functions for setting slot time and
timeouts and also implements the switch between short and long slot
time in 2.4 GHz

Move table init to tables_nphy.c, detect newer PHY which use different init.
We don't init newer PHYs yet but this at least shows what more is needed.

Subject: b43: N-PHY: update init code to match current specs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Previous init path was based on old specs from old driver. Update it
as much as possible leaving some TODOs for not implemented functions.

Subject: tcp: account SYN-ACK timeouts & retransmissions

Currently we don't increment SYN-ACK timeouts & retransmissions
although we do increment the same stats for SYN. We seem to have lost
the SYN-ACK accounting with the introduction of tcp_syn_recv_timer
(commit 2248761e in the netdev-vger-cvs tree).

This patch fixes this issue. In the process we also rename the v4/v6
syn/ack retransmit functions for clarity. We also add a new
request_socket operations (syn_ack_timeout) so we can keep code in
inet_connection_sock.c protocol agnostic.

From 2c8c1e7297e19bdef3c178c3ea41d898a7716e3e Mon Sep 17 00:00:00 2001
From: Alexey Dobriyan <adobriyan@gmail.com>
Date: Sun, 17 Jan 2010 03:35:32 +0000
Subject: net: spread __net_init, __net_exit

__net_init/__net_exit are apparently not going away, so use them
to full extent.

In some cases __net_init was removed, because it was called from
__net_exit code.

Subject: bnx2: Refine statistics code.

Refine the statistics macros by passing in just the name of the
counter field.  This makes it a lot easier and cleaner to add
counters saved before the last reset in the next patch.

Subject: bnx2: Save statistics during reset.

MTU changes, ring size changes, etc cause the chip to be reset and the
statisctics flushed.  To keep track of the accumulated statistics, we
add code to save the whole statistics block before reset.  We also
modify the macros and statistics functions to return the sum of the
saved and current counters.

Based on original patch by Breno Leitao <leitao@linux.vnet.ibm.com>

Subject: netfilter: xtables: add struct xt_mtchk_param::net

Some complex match modules (like xt_hashlimit/xt_recent) want netns
information at constructor and destructor time. We propably can play
games at match destruction time, because netns can be passed in object,
but I think it's cleaner to explicitly pass netns.

Add ->net, make sure it's set from ebtables/iptables/ip6tables code.

Subject: netfilter: xtables: add struct xt_mtdtor_param::net

Add ->net to match destructor list like ->net in constructor list.

Make sure it's set in ebtables/iptables/ip6tables, this requires to
propagate netns up to *_unregister_table().

Subject: ppp_generic.c severly whitespace damanged by
 9c705260feea6ae329bc6b6d5f6d2ef0227eda0a

I was just looking at ppp_generic, and noticed that it fairly recently
(as in the last year) got rather mangled with many spaces turned into tabs
in places they very much shouldn't have been.  I tracked it down to commit
9c705260feea6ae329bc6b6d5f6d2ef0227eda0a (ppp: ppp_mp_explode() redesign).

I am amazed if that patch passed the patch checking script.  I have no
idea what kind of weird editor setting did this, but it has to have been a
weird editor setting or a very unfortunate search and replace gone wrong.
I only found it trying to apply a patch I was playing with and wondering
why it wouldn't apply.  Then I found there were tabs in the middle of
comments that used to be spaces.

Well here is a patch that should fix it up as far as I can tell.

Purely whitespace repair.  No actual code changes.

Subject: ipv4: allow warming up the ARP cache with request type gratuitous ARP

If the per device ARP_ACCEPT option is enable, currently we only allow
creating new ARP cache entries for response type gratuitous ARP.

Allowing gratuitous ARP to create new ARP entries (not only to update
existing ones) is useful when we want to avoid unnecessary delays for
the first packet of a stream.

This patch allows request type gratuitous ARP to create new ARP cache
entries as well. This is useful when we want to populate the ARP cache
entries for a large number of hosts on the same LAN.

Subject: mac80211: fix WMM AC default for non-QoS data frames

The WMM AC selection added to the monitor mode selection function
accidentally assigns non-QoS data frames to the same AC as mgmt frames
(VO). This is not serious, but should be fixed anyway. This patch
assigns them to the BE AC instead.

Subject: iwlwifi: add num_of_sos_stats to statistics counter

When uCode detects number of beacon missed consecutively above the
internal missed beacon threshold (set by uCode), it will reset and
re-tune the radio in order to get out of bad PHY state.

This "num_of_sos_states" counter monitors number of time uCode
encounters this bad condition and has to re-tune the radio.

This is a w/a for a hardware bug. the h/w bug may cause the Rx bit
(bit 15 before shifting it to 31) to clear when using interrupt coalescing.

This does not mean frames are lost - their processing is just delayed until
next interrupt arrives.

Subject: iwlwifi: remove extra statistics request from debugfs

When reading current ucode statistics information from debugfs, in
current implementation, it will always send a new "statistics request" to
uCode. In normal operation, uCode should report the statistics per beacon
interval. Remove this extra request to reduce the additional command exchanges
between driver and uCode.

Subject: mac80211: move and rename misc tx handler

This TX handler is used only for assigning the
station pointer in the control information, so
give it a better name. Also move it before rate
control.

Subject: mac80211: remove useless setting of IEEE80211_TX_INTFL_DONT_ENCRYPT

There's no value in setting a flag that will
never be checked after this point, this seems
to be legacy code -- I think previously the
flag was used to check whether to encrypt the
frame or not. Now, however, the flag need not
be set, and setting it actually interferes if
the frame will be processed again later.

Subject: mac80211: move control.hw_key assignment

When mac80211 asks a driver to encrypt a frame, it
must assign the control.hw_key pointer for it to
know which key to use etc. Currently, mac80211 does
this whenever it would software-encrypt a frame.

Change the logic of this code to assign the hw_key
pointer when selecting the key, and later check it
when deciding whether to encrypt the frame or let
it be encrypted by the hardware. This allows us to
later simply skip the encryption function since it
no longer modifies the TX control.

Subject: mac80211: re-enable re-transmission of filtered frames

In an earlier commit,

    mac80211: disable software retry for now

    Pavel Roskin reported a problem that seems to be due to
    software retry of already transmitted frames. It turns
    out that we've never done that correctly, but due to
    some recent changes it now crashes in the TX code. I've
    added a comment in the patch that explains the problem
    better and also points to possible solutions -- which
    I can't implement right now.

I disabled software retry of failed/filtered frames
because it was broken. With the work of the previous
patches, it now becomes fairly easy to re-enable it
by adding a flag indicating that the frame shouldn't
be modified, but still running it through the transmit
handlers to populate the control information.

Subject: cfg80211: rcu-ify rdev and wdev

Future code will need to look up rdev and wdev
within atomic sections, but currently we need
to lock a mutex for such lookups. Change the
list handling for both to be RCU-safe so that
we can look them up in rcu sections instead in
the future.

From: Felix Fietkau <nbd@openwrt.org>
Date: Sun, 17 Jan 2010 21:08:50 +0100
Subject: ath9k: fix RTS/CTS handling

The Tx DMA descriptor has two kinds of flags that select RTS/CTS usage.
The first one (global for the frame) selects whether RTS/CTS or
CTS-to-self should be used, the second one enables RTS/CTS or
CTS-to-self usage for an individual multi-rate-retry entry.
Previously the code preparing the descriptor only enabled the global
flag, if the first MRR series selected the local one.
Fix this by enabling the global flag if any of the MRR entries need it.
With this patch, rate control can properly select the use of RTS/CTS
for all MRR entries except the first one, which is the default behavior.

Subject: mac80211: Fixed a bug in IBSS merge

First, both beacons and probe responses can be used for IBSS merge.
Next, sdata->u.ibss.bssid was always true (and thus IBSS merge was
disabled). We should use sdata->u.ibss.fixed_bssid instead.

Subject: p54pci: move tx cleanup into tasklet

This patch moves the tx cleanup routines out of the critical
interrupt context and into the (previously known as rx) tasklet.

The main goal of this operation is to remove the extensive
usage of spin_lock_irqsaves in the generic p54common library.

The next step would be to modify p54usb to do the
rx processing inside a tasklet (just like usbnet).

Subject: libertas: Set/clear WPA keys before the WEP ones

With the v10 firmware running on 8688 HW, clearing WPA keys after setting the
WEP key prevents us from being able to associate with WEP APs.
Swapping the calling order for assoc_helper_wpa_keys() and
assoc_helper_wep_keys fixes that issue.

Subject: nl80211: Allow association to change channels during reassociation

nl80211_associate() was rejecting (re)association attempts with EBUSY
in some cases where we are currently associated with an AP that uses
different channel from the destination AP. Fix this by passing the
current wdev to rdev_fixed_channel() in the same way that was already
done for join-IBSS and connect commands. This allows the fixedchan
check to skipped for the current wdev and allows the reassociation to
proceed.

Subject: ath9k: make tx power config changes take effect immediatley

Users wishing to tweak tx power want it to happen immediately,
try to respect that. This was tested by Lorenzo by measuring the
received signal strength from an AP with ath9k and the patch.

Changing the tx power on the AP produced these results:

1) iwconfig wlan0 txpower 20 ---> Rx power -37dbm
2) iwconfig wlan0 txpower 15 ---> Rx power -41dbm
3) iwconfig wlan0 txpower 10 ---> Rx power -45dbm
4) iwconfig wlan0 txpower 5 ---> Rx power -51dbm
5) iwconfig wlan0 txpower 0 ---> Rx power -37dbm

The result with 0 is an anomoly and would need to be
addressed through a separate patch.

This patch addresses a number of minor (mostly cosmetic) issues relating
to the configuration of TIPC, including the following:

- Corrects range limits for maximum number of ports per node
- Adds missing range limits for size of log buffer
- Removes configuration setting relating to unsupported slave node capability
- Standardizes description and help text wording for configuration settings
- Removes unneeded blank spaces

Subject: tg3: Abort phy init for 5717 serdes devices

The 5717 serdes devices have a different phy register layout than all
other previous serdes devices.  This patch aborts the phy init sequence
in tg3_phy_reset() if the device is a 5717 serdes.  It also aborts the
tg3_phy_toggle_apd() operation.  Most other operations in the MII_SERDES
path are O.K.

Subject: tg3: Supply a nicaddr for 57765 jumbo RCB

The 57765 needs the driver to supply a nic address to the jumbo RCB,
just like all other devices except the 5717.  This patch changes the
test to single out the 5717 rather than maintain a lengthy whitelist of
asic revs.

Subject: tg3: Fix tx mailbox initialization

If a device supports MSI-X interrupts, the driver assumes TSS will be
available.  This is not true for the 57765.  This patch changes the code
so that only the default tx mailbox is initialized if TSS is not
available.

Subject: cfg80211: export multiple MAC addresses in sysfs

If a device has multiple MAC addresses, userspace will
need to know about that. Similarly, if it allows the
MAC addresses to vary by a bitmask.

If a driver exports multiple addresses, it is assumed
that it will be able to deal with that many different
addresses, which need not necessarily match the ones
programmed into the device; if a mask is set then the
device should deal addresses within that mask based
on an arbitrary "base address".

To test it all and show how it is used, add support
to hwsim even though it can't actually deal with
addresses different from the default.

Subject: mac80211: Account HT Control field in Data frame hdrlen according to
 802.11n-2009

ieee80211_hdrlen() should account account new HT Control field in 802.11
data frame header introduced by IEEE 802.11n standard.

According to 802.11n-2009 HT Control field is present in data frames
when both of following are met:

   1. It is QoS data frame.
   2. Order bit is set in Frame Control field.

The change might be totally compatible with legacy non-11n aware frames,
because 802.11-2007 standard states that "all QoS STAs set this subfield
to 0".

Subject: ath5k: dont use external sleep clock in AP mode

When using the external sleep clock in AP mode, the
TSF increments too quickly, causing beacon interval
to be much lower than it is supposed to be, resulting
in lots of beacon-not-ready interrupts.

This fixes http://bugzilla.kernel.org/show_bug.cgi?id=14802.

Subject: ath5k: fix setup for CAB queue

The beacon sent gating doesn't seem to work with any combination
of flags.  Thus, buffered frames tend to stay buffered forever,
using up tx descriptors.

Instead, use the DBA gating and hold transmission of the buffered
frames until 80% of the beacon interval has elapsed using the ready
time.  This fixes the following error in AP mode:

   ath5k phy0: no further txbuf available, dropping packet

Add a comment to acknowledge that this isn't the best solution.

From 4bb29f8c390fb7be207ec3f11b9d30ccdf1cb6ac Mon Sep 17 00:00:00 2001

Subject: mac80211: fix rx data handling for non-data frames on multiple vifs

The loop that passes non-data frames to all relevant vifs inside the
__ieee80211_rx_handle_packet keeps a pointer to the previous sdata to
avoid having to make unnecessary copies of the frame it's handling.
This led to a bug that caused it to apply the ieee80211_rx_data state
to the wrong interface, thereby either missing the rx.sta pointer or
having it assigned where it shouldn't be.
This breaks (among other things) aggregation on some vifs, as action
frame exchages are dropped to the cooked monitor interface due to
rx->sta being NULL.
Fix this by restructuring the loop so that it prepares the rx data just
before making the skb copy and calling the rx handlers.

Subject: mac80211: add missing key check

ieee80211_tx_h_select_key might decide that a frame
need not be encrypted at all, in which case it will
clear tx->key. In that case it may crash if a key
was previously selected, e.g. as the default key.

This is also due to my patch
"mac80211: move control.hw_key assignment".

When VFs are allocated (as indicated by adapter->num_vfs is non-zero) then
the PF pool is no longer zero.  Instead it will be the same as the number
of VFs allocated.  When setting the VLVF entry for the PF we need to use
the correct pool otherwise the PF will get VLAN packets from the wire
because the packet will pass VFTA filtering and the PF has the default
pool, but it will not get VLAN packets from the VFs because it has
not set the correct pool bit in the VLVF entry.

Subject: ixgbe: Allow the VF driver to be loaded before the PF driver

The PF Reset Done bit should not be set in the extended control register
until the PF has actually completed the bring up process.  It is a mis-
interpretation of the purpose of this bit to assume it should be set
when the physical reset of the device is done.  Instead it should be used
to indicate to the VFs when the PF is ready to provide them with required
services.  This is not until after the PF is finished coming up and ready
to process mailbox events.

Subject: ixgbe: Improve reset coordination between the PF and the VF

Inadequate coordination between the PF driver and the VF driver results
in tx hangs in the VF driver when you perform certain actions that will
lead to a re-init of the PF.  Add feature to notify active VFs when the PF
is about to re-initialize so that the VFs can take appropriate action.

Subject: IP: Send an ICMP "Fragment Reassembly Timeout" message when enabling
 connection track

No matter whether connection track is enabled, an end host should send
an ICMPv4 "Fragment Reassembly Timeout" message when defrag timeout.
The reasons are following two points:

1. RFC 792 says:
   >>>> >> > >   If a host reassembling a fragmented datagram cannot complete the
   >>>> >> > >   reassembly due to missing fragments within its time limit it
   >>>> >> > >   discards the datagram, and it may send a time exceeded message.
   >>>> >> > >
   >>>> >> > >   If fragment zero is not available then no time exceeded need be
   >>>> >> > >   sent at all.
   >>>> >> > >
   >>>> >> > > Read more: http://www.faqs.org/rfcs/rfc792.html#ixzz0aOXRD7Wp

2. Patrick McHardy also agrees with this opinion.   :-)
   About the discussion of this opinion, refer to http://patchwork.ozlabs.org/patch/41649

The patch fixed the problem like this:
When enabling connection track, fragments are received at PRE_ROUTING HOOK.
If they are failed to reassemble, ip_expire() will be called.
Before sending an ICMP "Fragment Reassembly Timeout" message,
the patch searches router table to get the destination entry only for host type.

The patch has been tested on both host type and route type.

Based on patch from Sridhar Samudrala

The following patch fixes the check for IPv6 GSO packet in ixgbevf
driver to use skb_is_gso_v6(). SKB_GSO_DODGY is also set
when packets are forwarded from a guest.

Subject: mac80211: fix tx select key null pointer crash with hostapd

Pavel Roskin reported a crash in ieee80211_tx_h_select_key():

http://marc.info/?l=linux-wireless&m=126419655108528&w=2

This is a regression from patch "mac80211: move control.hw_key assignment".
Fix it as suggested by Johannes, adding an else statement to make sure
that tx->key is not accessed when it's null.

Compile-tested only.

Subject: iwlwifi: configure missed beacon threshold

Add support to configure missed beacon threshold, by default, if receive
"missed beacon" notification from uCode and has more than 5 consecutive
beacon missed, then perform sensitivity calibration; with this change,
allow user to adjust the missed beacon threshold from debugfs in case
more sensitivity calibration required for better performance in noisy
environment

The default value (=5) should be good enough for the normal condition,
but for very noisy environment, more sensitivity calibration could help
improve the throughput, so by setting the missed beacon threshold to
lower number, user might experience better performance result.

Subject: iwlwifi: add function to reset/tune radio if needed

Adding "radio reset" function to help reset and stabilize the radio.

During normal operation, sometime for unknown reason, radio encounter
problem and can not recover by itself; the best way to
recover from it is to reset and re-tune the radio. Currently, there is
no RF reset command available, but since radio will get reset when
switching channel, use internal hw scan request to force radio
reset and get back to normal operation state.

The internal hw scan will only perform passive scan on the first
available channel (not the channel being used) in associated state. The
request should be ignored if already performing scan operation or STA is
not in associated state.

Also include an "internal_scan" debugfs file to help trigger the
internal scan from user mode.

Subject: iwlwifi: Fix A band scanning when associated

This patch allows A band to be scanned when driver is associated to AP.
Scan mechanism is that mac80211/cfg80211 requests driver to scan G band
first and then immediately to scan A band. Original code require
driver to wait for 2 seconds after any scan before another scan will be
performed. This caused driver to service G band scan request from
mac80211/cfg80211 but deny the A band scan request.

 needed

Add additional logic for internal scan routine to control how
frequent this function should be performed.

The intent of this function is to reset/re-tune the radio and bring the
RF/PHY back to normal state, it does not make sense calling it too
frequent,
if reset the radio can not bring it back to normal state, it indicate
there are other reason to cause the radio not operate correctly.

Subject: iwlwifi: Tune radio to prevent unexpected behavior

We have seen the throughput dropped due to external noisy environment
and the radio is out of tune.  There are lot of plcp errors indicating
this condition. Eventually the station can get de-authenticated by the
Access Point.  By resetting and tuning the radio, the plcp errors are
reduced or eliminated and the throughput starts to rise.

To prevent unexpected behavior such as drop in throughput or deauthentication,
- The change provides the driver feature to monitor and tune the radio base on
the statistics notification from the uCode.
- It also allows the setting of the plcp error rate threshold via
the plcp_delta under debugfs interface.

Subject: iwlwifi: cleanup station adding code

The work done when a station is added is very similar whether the station
is added synchronously or asynchronously. Centralize this work. At the same
time increase the status flags being checked for when the command returns
with accompanying debug messages. Also increase checking when setting the
"ucode active" state with accompanying debugging.

This work is done in preparation for station notification support.

Subject: iwlwifi: make broadcast station addition generic

Add function pointer for broadcast station addition so that we can call it
in from iwlcore at a later time. We only distinguish between iwlagn and
iwl3945 broadcast station addition. For the iwl3945 station addition we add
that function to iwlcore since that is where most station functionality
resides, making it part of iwl3945 will require significant code
reorganization that will dilute station management functionality. This
seems to be an efficient solution.

It may seem as though we are removing error checking when adding the 3945
broadcast station but this error checking was never really necessary since
the function returns the station id and the broadcast station id is always
set.

Subject: iwlwifi: module parameter to enable/disable bt co-exist

Adding "bt_coex_active" module parameter for iwlcore to enable/disable
BT coexist; if bt_coex_active is true (default), uCode will do kill/defer
every time the priority line is asserted (BT is sending signals on the
priority line in the PCIx). By disable the bt_coex_active, uCode will
ignore the BT activity and perform the normal operation.

Users might experience transmit issue on some platform due to this
WiFi/BT co-exist problem. The possible symptoms are: NetworkManager and
other similar programs can scan and find all the available APs, but will
timeout and unable to associate with any of the APs; no out-going frames
can be found with wireless sniffer tools.

On those platforms, WiFi communication can be restored by set "bt_coex_active"
module parameter to "false"

It is better to first notify cfg80211 about the hw
rfkill state (so the rfkill device that will be
registered won't have the wrong state while being
registered), and the power/tt variable init can
(and probably should) also be done first.

Also rename iwl_setup_mac to
iwl_mac_setup_register to better describe what it
really does.

the large chunk of variables can completely go

Subject: iwlwifi: check endianness annotations by default

sparse won't check endianness annotations by
default, but iwlwifi is and should be clean
so we can make sparse check them on it.

Subject: iwlwifi: cleanup spectrum measurement command support

In iwlagn the support for spectrum measurement command has been
disabled since v2.6.29 without any requests for it. In addition to this
when this command is indeed enabled it has been found to trigger firmware
SYSASSERT on at least 4965 and 5100 hardware (see
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=1952 ). Since then
this code has been bitrotting and cannot just be enabled without porting.

Remove support for spectrum measurement command from iwlagn. It can be
added back if there is a future need and the firmware problem it triggers
has been fixed. Support for the spectrim measurement notification remains
as it has been enabled all the time.

In addition to this remove the 3945 spectrum measurement command Kconfig
option and make this command always supported. The code added by this
enabling is minimal and only run when user triggers a spectrum measurement
request via sysfs.

Subject: iwlwifi: fix throughput degradation in aggregation mode

The following commit

	commit e4da8c37af626001ff704fb29ea14eb58f5f7208
	Author: Johannes Berg <johannes@sipsolutions.net>
	Date:   Wed Dec 23 13:15:43 2009 +0100

	   mac80211: make off-channel work generic

triggered a bug in iwlwifi where HT parameters would not be correctly set in
some mac80211 pathways. The aggregation (and possibly other) station flags were
not being set, which limited the size of aggregation blocks and reduced
throughput at high rates.

>From Johannes:
"""
Due to Wey-Yi's patch to use the set-channel command when the channel changes
while associated, we don't get a full new RXON. Therefore, we don't re-set the
rxon-station either. However, under some circumstances that apparently have
gotten more likely mac80211 will first set up the BSS info, then add the
station and then switch to an HT channel type.

Therefore, the check for "priv->current_ht_config.is_ht" in
iwl_rxon_add_station() will hit false and not fill in the HT information.

However, that check can just be removed, which is the easiest fix for all this,
because the HT capa struct is always there, just could possibly have the
ht_supported member set to false.
"""

Subject: ath9k: improve max rate retry handling

ath9k currently forces hw->max_rate_tries to 4 to work around rate
control inefficiencies. This has some negative side effects, such as
rate_control_send_low also using a maximum of 4 tries, which could
negatively affect reliability of unicast management frames.
This patch pushes the retry limit to the rate control instead, and
allows it to use more tries on the last stage to prevent unnecessary
packet loss.

Subject: b43: Workaround circular locking in hw-tkip key update callback

The TKIP key update callback is called from the RX path, where the driver
mutex is already locked. This results in a circular locking bug.
Avoid this by removing the lock.

Johannes noted that there is a separate bug: The callback still breaks on SDIO
hardware, because SDIO hardware access needs to sleep, but we are not allowed
to sleep in the callback due to mac80211's RCU locking.

ieee80211_work_rx_mgmt currently enqueues various management frames,
including deauth and disassoc frames, however the function
ieee80211_work_rx_queued_mgmt does not handle these, as they should
only occur if the AP is buggy. It does emit a WARN_ON when this happens
though, and several users have reported such instances.
Fix the WARN_ON by not queueing such frames in the first place.

        mac80211: move control.hw_key assignment

I inserted code testing the wrong flags field,
which means that the test is almost always true
(it's really testing for the peer's WMM support)
and thus the later parts of the stack assume hw
crypto will be done even if that's not true.

Obviously, that broke software crypto. Maxim
said so specifically, and Jochen probably uses
some cipher that iwl3945 doesn't support in
hardware, which might also explain that Maxim
reports that even hw crypto is broken.

Fix this to test the right flags field.

Subject: mac80211: track work started through callbacks

Currently, the remain_on_channel work callback needs
to track in its own data structure whether the work
was just started or not. By reordering some code this
becomes unnecessary, the generic wk->started variable
can still be 'false' on the first invocation and only
be 'true' on actual timeout invocations, so that the
extra variable can be removed.

Subject: mac80211: wait for beacon before enabling powersave

Because DTIM information is required for powersave
but is only conveyed in beacons, wait for a beacon
before enabling powersave, and change the way the
information is conveyed to the driver accordingly.

mwl8k doesn't currently seem to implement PS but
requires the DTIM period in a different way; after
talking to Lennert we agreed to just have mwl8k do
the parsing itself in the finalize_join work.

Subject: net/atm/lec.c: checkpatch cleanups

Convert #include <asm... to #include <linux...
Mostly 80 column wrapped.
Spacing cleanups
Convert printks to pr_<level>
Use print_hex_dump
Move embedded assigns out of tests
Move trailing statements to new lines
Remove unnecessary braces around single line statements
switch/case cleanups
Removed paren around returns
Use %pM
Moved leading continuation logical tests to end of previous line

Subject: net/atm/mpc.c: checkpatch cleanups

Convert #include <asm... to #include <linux...
Add printk argument verification to dprintk and ddprintk
Spacing cleanups
Mostly 80 column wrapped.
printk->pr_info and pr_cont
Moved labels to column 1
Move trailing statements to new lines
switch/case cleanups
	remove unnecessary breaks after returns
Remove unnecessary braces around single line statements

Subject: netns xfrm: xfrm6_tunnel in netns

I'm not sure about rcu stuff near kmem cache destruction:
* checks for non-empty hashes look bogus, they're done _before_
  rcu_berrier()
* unregistering netns ops is done before kmem_cache destoy
  (as it should), and unregistering involves rcu barriers by itself

So it looks nothing should be done.

Subject: ps3_gelic_wireless: Remove PS3 gelic legacy wpa support

The current PS3 gelic wireless driver has support for wireless
extensions. The original PS3 gelic wireless driver exposed a
dedicated API for a dedicated wpa_supplicant driver. This old
API could be enabled with CONFIG_GELIC_WIRELESS_OLD_PSK_INTERFACE,
however, as this is not being used by any distros, and it is being
removed from the driver and from wpa_supplicant.

Subject: sched: add head drop fifo queue

This adds an additional queuing strategy, called pfifo_head_drop,
to remove the oldest skb in the case of an overflow within the queue -
the head element - instead of the last skb (tail). To remove the oldest
skb in congested situations is useful for sensor network environments
where newer packets reflect the superior information.

Subject: iwlwifi: optimize power saving

In hostap AP mode, every time the client sends the AP
a packet the STA_NOTIFY_AWAKE code is sent from mac80211.
This results in a command being sent to the uCode even if
the client was not asleep.

The following simple patch has fixed the issue for me without any
degradation that I can find.

Subject: iwlwifi: fix locking in iwl_mac_add_interface

The corresponding iwl_mac_remove_interface only
acquires the mutex, leading me to believe that
the spinlock is not necessary. However, this
doesn't actually acquire the mutex around the
vif pointer check and assignment, fix that.

Subject: iwlwifi: iwl_power_update_mode always hold mutex

iwl_power_update_mode expects to be called with mutex held, for example to
protect priv->vif. Only one caller currently does not do this, fix this.
Also, add a comment to iwl_power_update_mode to indicate this requirement.

Convert printks to dev_<level> where a dev is available
Convert printks to pr_<level> where not
Coalesce format strings
Change print formats with %d.dx to %0dx
Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Remove 'DRV_NAME ": ' from logging messages
Convert commented out printks to pr_debug

Subject: tulip/winbond-840.c: Use dev_<level> and pr_<level>

Convert printks to dev_<level> where a dev is available
Convert printks to pr_<level> where not
Coalesce format strings
Change print formats with %d.dx to %0dx
Convert %d.%d.%d.%d to %pI4

Subject: cfg80211: avoid flushing the global workqueue for core reg hints

When cfg80211 starts it will send a core regulatory hint. This is
sent to the global workqueue but we force processing of it by
flushing the global workqueue. The flushing was done since
cfg80211 needs last_request to always be populated.

Avoid flushing the global workqueue by processing the work
required immediately instead of putting it into a linked
list and processing it after the flush.

Subject: cfg80211: add regulatory hint disconnect support

This adds a new regulatory hint to be used when we know all
devices have been disconnected and idle. This can happen
when we suspend, for instance. When we disconnect we can
no longer assume the same regulatory rules learned from
a country IE or beacon hints are applicable so restore
regulatory settings to an initial state.

Since driver hints are cached on the wiphy that called
the hint, those hints are not reproduced onto cfg80211
as the wiphy will respect its own wiphy->regd regardless.

Subject: mac80211: reduce stack usage in sta_ht_capa_read()

The maximal size of the "ht_capa" file is 430 bytes.  In most cases,
it's much shorter.  Use a 512 byte long buffer.  1024 bytes is too much
and causes a warning with CONFIG_FRAME_WARN=1024.

Subject: mac80211: fix sta lookup for received action frames on an AP VLAN

When looking for a matching interface, __ieee80211_rx_handle_packet
loops over all active interfaces, looking for matching stations.
Because AP VLAN interfaces are not processed as part of this loop, it
needs to use sta_info_get_bss instead of sta_info_get in order to find
a STA that has been moved to a VLAN.
This fixes issues with aggregation setup/teardown.

Subject: mac80211: fix monitor mode tx radiotap header handling

When an injected frame gets buffered for a powersave STA or filtered
and retransmitted, mac80211 attempts to parse the radiotap header
again, which doesn't work because it's gone at that point.
This patch adds a new flag for checking the availability of a radiotap
header, so that it only attempts to parse it once, reusing the tx info
on the next call to ieee80211_tx().
This fixes severe issues with rekeying in AP mode.

When injecting frames, mac80211 currently looks for the first AP
interface that matches the source address of the injected frame.
This breaks when such a frame is directed at a STA that has been moved
to a VLAN. This patch fixes it by using sta_info_get_bss instead of
sta_info_get, which also finds stations belonging to a VLAN interface
of the same BSS as the AP interface.

Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access
to common->bus_ops, which is already freed as part of the device data.

Remove the cleanup field in struct ath_bus_ops, as it was never used
properly.  Remove ath_bus_cleanup().  Merge cleanup functions in place
of the ath_bus_cleanup() calls.  Take care not to use any device data
after ieee80211_free_hw().

Subject: netfilter: xt_TCPMSS: SYN packets are allowed to contain data

The TCPMSS target is dropping SYN packets where:
  1) There is data, or
  2) The data offset makes the TCP header larger than the packet.

Both of these result in an error level printk. This printk has been
removed.

This change avoids dropping SYN packets containing data. If there
is also no MSS option (as well as data), one will not be added
because of possible complications due to the increased packet size.

receiption by using ml_priv" the formerly used hlist of receiver lists for

The hlist content ensured only CAN netdevices to be accessed by the

the hlist receiver implementation.

This patch re-introduces the check for CAN netdevices in can_rx_(un)register().

Subject: igmp: fix ip_mc_sf_allow race [v5]

Almost all igmp functions accessing inet->mc_list are protected by
rtnl_lock(), but there is one exception which is ip_mc_sf_allow(),
so there is a chance of either ip_mc_drop_socket or ip_mc_leave_group
remove an entry while ip_mc_sf_allow is running causing a crash.

Subject: airo: fix setting zero length WEP key

Patch prevents call set_wep_key() with zero key length. That fix long
standing regression since commit c0380693520b1a1e4f756799a0edc379378b462a
"airo: clean up WEP key operations". Additionally print call trace when
someone will try to use improper parameters, and remove key.len = 0
assignment, because it is in not possible code path.

Some single chip family devices are sold in the market with
802.11n bonded out, these have no hardware capability for
802.11n but ath9k can still support them. These are called
AR2427.

Subject: virtio: Add ability to detach unused buffers from vrings

There's currently no way for a virtio driver to ask for unused
buffers, so it has to keep a list itself to reclaim them at shutdown.
This is redundant, since virtio_ring stores that information.  So
add a new hook to do this.

Subject: virtio_net: Defer skb allocation in receive path Date: Wed, 13 Jan
 2010 12:53:38 -0800

virtio_net receives packets from its pre-allocated vring buffers, then it
delivers these packets to upper layer protocols as skb buffs. So it's not
necessary to pre-allocate skb for each mergable buffer, then frees extra
skbs when buffers are merged into a large packet. This patch has deferred
skb allocation in receiving packets for both big packets and mergeable buffers
to reduce skb pre-allocations and skb frees. It frees unused buffers by calling
detach_unused_buf in vring, so recv skb queue is not needed.

Subject: netfilter: xt_hashlimit: fix race condition and simplify locking

As noticed by Shin Hong <hongshin@gmail.com>, there is a race between
htable_find_get() and htable_put():

htable_put():				htable_find_get():

					spin_lock_bh(&hashlimit_lock);
					<search entry>
atomic_dec_and_test(&hinfo->use)
					atomic_inc(&hinfo->use)
					spin_unlock_bh(&hashlimit_lock)
					return hinfo;
spin_lock_bh(&hashlimit_lock);
hlist_del(&hinfo->node);
spin_unlock_bh(&hashlimit_lock);
htable_destroy(hinfo);

The entire locking concept is overly complicated, tables are only
created/referenced and released in process context, so a single
mutex works just fine. Remove the hashinfo_spinlock and atomic
reference count and use the mutex to protect table lookups/creation
and reference count changes.

Subject: netfilter: ctnetlink: only assign helpers for matching protocols

Make sure not to assign a helper for a different network or transport
layer protocol to a connection.

Additionally change expectation deletion by helper to compare the name
directly - there might be multiple helper registrations using the same
name, currently one of them is chosen in an unpredictable manner and
only those expectations are removed.

Subject: netfilter: nf_conntrack: split up IPCT_STATUS event

Split up the IPCT_STATUS event into an IPCT_REPLY event, which is generated
when the IPS_SEEN_REPLY bit is set, and an IPCT_ASSURED event, which is
generated when the IPS_ASSURED bit is set.

In combination with a following patch to support selective event delivery,
this can be used for "sparse" conntrack replication: start replicating the
conntrack entry after it reached the ASSURED state and that way it's SYN-flood
resistant.

Subject: netfilter: ctnetlink: support selective event delivery

Add two masks for conntrack end expectation events to struct nf_conntrack_ecache
and use them to filter events. Their default value is "all events" when the
event sysctl is on and "no events" when it is off. A following patch will add
specific initializations. Expectation events depend on the ecache struct of
their master conntrack.

Support initializing selected parameters of new conntrack entries from a
"conntrack template", which is a specially marked conntrack entry attached
to the skb.

Currently the helper and the event delivery masks can be initialized this

From 84f3bb9ae9db90f7fb15d98b55279a58ab1b2363 Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>
Date: Wed, 3 Feb 2010 17:17:06 +0100
Subject: netfilter: xtables: add CT target

Add a new target for the raw table, which can be used to specify conntrack
parameters for specific connections, f.i. the conntrack helper.

The target attaches a "template" connection tracking entry to the skb, which
is used by the conntrack core when initializing a new conntrack.

Subject: MCS7830 USB-Ether: add Rx error support

ChangeLog:
- evaluate Rx error statistics from trailing Rx status byte
- add driver TODO list
- add myself to authors

Quilt series run-tested, based on 2.6.33-rc4 (net-2.6.git mcs7830 has idle history,
should be good to go).

Subject: MCS7830 USB-Ether: resume _with_ working link, via .reset_resume
 support

ChangeLog:
Implement .reset_resume support to retain a live network connection
during suspend despite USB power loss.
- rework operation to reference cached data in mcs7830_data and
  netdev->dev_addr
- update netdev->dev_addr only in case new MAC was set successfully
. Tests done:
  . ethtool -d pre-/post-suspend: register values match
  . running ssh session suspend, resume: works
  . ifdown device, suspend, resume: works
  . ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1
    after card replug works)
  . verified identical MAC in ifconfig post-resume
    (ok, should be verified on network side to be fully certain...)

Keywords: suspend resume network connection dead interface down

Subject: can: add support for CAN interface cards based on the PLX90xx PCI
 bridge

This driver is for CAN interface cards based on the PLX90xx PCI bridge.
Driver supports now:
 - Adlink PCI-7841/cPCI-7841 card (http://www.adlinktech.com/)
 - Adlink PCI-7841/cPCI-7841 SE card
 - Marathon CAN-bus-PCI card (http://www.marathon.ru/)
 - TEWS TECHNOLOGIES TPMC810 card (http://www.tews.com/)

Changes since v1:
 - Added some defines for static inline int plx_pci_check_sja1000(...)
 - static struct pci_device_id plx_pci_tbl[] replaced by
   static DEFINE_PCI_DEVICE_TABLE(plx_pci_tbl)
 - Typo fixed

Subject: sfc: Replace PHY MDIO test with an 'alive' test

SFC9000-family boards do not all use MDIO PHYs, so we need a different
test for PHY aliveness.

Introduce a PHY operation test_alive().  For PHYs attached to Falcon,
use a common implementation based on the existing PHY MDIO test.
For PHYs managed through MCDI, use the appropriate MCDI request.

Change test name in ethtool from 'core mdio' to 'phy alive'.

Rename test_results::mdio to phy_alive and test_results::phy to phy_ext.

Subject: ixgbe: only process one ixgbe_watchdog_task at a time.

Processing multiple ixgbe_watchdog_task calls may cause
the link_up variable and IXGBE_FLAG_NEED_LINK_UPDATE flag
to be set incorrectly.  In the worse case this is causing
the netif_carrier_off to be called inappropriately which
results in an interface that can't be brought up.

Although schedule_work() will only schedule the task if
it is not already on the work queue the WORK_STRUCT_PENDING
bits are cleared just before calling the work function.
This allows WORK_STRUCT_PENDING to be cleared, the work
function to start and meanwhile schedule another task.

This patch adds a mutex to the watchdog task. This bug is
actualized by changing DCB settings or doing extended
cable pull or reset tests.

This patch adds a call to pci_save_state() immediately after
the call to pci_restore_state(). Due to a change in the behavior
of pci_restore_state() it is necessary to call pci_save_state()
to keep the state_saved flag. This patch is based on a similar
patch for ixgbe.

Subject: ixgbe: Allocate driver resources per NUMA node

The default policy for the current driver is to do all its memory
allocation on whatever processor is running insmod/modprobe.  This
is less than optimal.

This driver's default mode of operation will be to use each node for each
subsequent transmit/receive queue.  The most efficient allocation will be
to then have the interrupts bound in such a way as to match up the
interrupt of the queue to the cpu where its memory was allocated.

This patch allocates the ring structures themselves on each
NUMA node along with the buffer_info structures.  This way we
don't allocate the entire ring memory on a single node in one
big block, thus reducing NUMA node memory crosstalk.

Subject: net: maintain namespace isolation between vlan and real device

In the vlan and macvlan drivers, the start_xmit function forwards
data to the dev_queue_xmit function for another device, which may
potentially belong to a different namespace.

To make sure that classification stays within a single namespace,
this resets the potentially critical fields.

Subject: macvlan: allow multiple driver backends

This makes it possible to hook into the macvlan driver
from another kernel module. In particular, the goal is
to extend it with the macvtap backend that provides
a tun/tap compatible interface directly on the macvlan
device.

Subject: net: macvtap driver

In order to use macvlan with qemu and other tools that require
a tap file descriptor, the macvtap driver adds a small backend
with a character device with the same interface as the tun
driver, with a minimum set of features.

Macvtap interfaces are created in the same way as macvlan
interfaces using ip link, but the netif is just used as a
handle for configuration and accounting, while the data
goes through the chardev. Each macvtap interface has its
own character device, simplifying permission management
significantly over the generic tun/tap driver.

Subject: can: mcp251x: Move to threaded interrupts instead of workqueues.

This patch addresses concerns about efficiency of handling incoming
packets. Handling of interrupts is done in a threaded interrupt handler
which has a smaller latency than workqueues. This change needed a rework
of the locking scheme that was much simplified. Some other (more or less
longstanding) bugs are fixed: utilization of just half of the RX
buffers, useless wait for interrupt on open, more reliable reset
sequence. The MERR interrupt is not used anymore: it overloads the CPU
in error-passive state without any additional information. One shot mode
is disabled because it's not clear if it can be handled efficiently on
this CAN controller.

Subject: sky2: hand receive DMA mapping failures

If receive buffer mapping failed, then it was possible to get
stuck with unmapped receive buffer in DMA ring.

This would be an extremely rare condition because the driver had just
released the map for the last receive so it should be able to get
another map again (in soft-irq).

Subject: net: use helpers to access mc list V2

This patch introduces the similar helpers as those already done for uc list.
However multicast lists are no list_head lists but "mademanually". The three
macros added by this patch will make the transition of mc_list to list_head
smooth in two steps:

1) convert all drivers to use these macros (with the original iterator of type
   "struct dev_mc_list")
2) once all drivers are converted, convert list type and iterators to "struct
   netdev_hw_addr" in one patch.

>From now on, drivers can (and should) use "netdev_for_each_mc_addr" to iterate
over the addresses with iterator of type "struct netdev_hw_addr". Also macros
"netdev_mc_count" and "netdev_mc_empty" to read list's length. This is the state
which should be reached in all drivers.

Subject: ipv4: obsolete config in kernel source (IP_ROUTE_PERVASIVE)

CONFIG_IP_ROUTE_PERVASIVE is missing a corresponding config
IP_ROUTE_PERVASIVE somewhere in KConfig (and missing it for ages
already) so it looks like some aging artefact no longer needed.

Therefor this patch kills of the only remaining reference to that
config Item removing the already unrechable code snipet.

Subject: qlge: removing unreachable block of code

Currently the qlge_change_mtu() is never called if the new_mtu is
equal current MTU, due this condition on dev_set_mtu():

        if (new_mtu == dev->mtu)
                return 0;

So, this block of code is never reached and is being removed.

From: Sridhar Samudrala <sri@us.ibm.com>
Date: Thu, 4 Feb 2010 20:24:10 -0800
Subject: packet: Add GSO/csum offload support.

This patch adds GSO/checksum offload to af_packet sockets using
virtio_net_hdr. Based on Rusty's patch to add this support to tun.
It allows GSO/checksum offload to be enabled when using raw socket
backend with virtio_net.
Adds PACKET_VNET_HDR socket option to prepend virtio_net_hdr in the
receive path and process/skip virtio_net_hdr in the send path. This
option is only allowed with SOCK_RAW sockets attached to ethernet
type devices.

v2 updates
----------
Michael's Comments
- Perform length check in packet_snd() when GSO is off even when
  vnet_hdr is present.
- Check for SKB_GSO_FCOE type and return -EINVAL
- don't allow tx/rx ring when vnet_hdr is enabled.
Herbert's Comments
- Removed ethernet specific code.
- protocol value is assumed to be passed in by the caller.

Subject: packet: Kill CONFIG_PACKET_MMAP.

Early on this was an experimental facility that few
people other than Alexey Kuznetsov played with.

Now it's a pretty fundamental thing and as people add
more features to AF_PACKET sockets this config options
creates ifdef spaghetti.

So kill it off.

Subject: mac80211_hwsim: add fake hw scan handler

For debugging hardware scan trigger/complete
functionality, it was useful to have code in
hwsim that pretends to do a hardware scan.

This code could be extended to actually do the
scan, but for now it was sufficient for me to
only pretend. Since hwsim was written to ease
debugging, it only makes sense to add it to it
permanently.

Upstream radiotap has adopted the namespace
proposal David Young made and I then took care
of, for which I had adapted the radiotap parser
as a library outside the kernel. This brings
the in-kernel parser up to speed.

Subject: mac80211: don't probe if we have probe response

We can now easily determine whether we already
have probe response information for the BSS we
are asked to connect to, in which case there's
little point in probing the BSS again.

Subject: mac80211: allow station add/remove to sleep

Many drivers would like to sleep during station
addition and removal, and currently have a high
complexity there from not being able to.

This introduces two new callbacks sta_add() and
sta_remove() that drivers can implement instead
of using sta_notify() and that can sleep, and
the new sta_add() callback is also allowed to
fail.

The reason we didn't do this previously is that
the IBSS code wants to insert stations from the
RX path, which is a tasklet, so cannot sleep.
This patch will keep the station allocation in
that path, but moves adding the station to the
driver out of line. Since the addition can now
fail, we can have IBSS peer structs the driver
rejected -- in that case we still talk to the
station but never tell the driver about it in
the control.sta pointer. If there will ever be
a driver that has a low limit on the number of
stations and that cannot talk to any stations
that are not known to it, we need to do come up
with a new strategy of handling larger IBSSs,
maybe quicker expiry or rejecting peers.

Also clean up the CONF_PS part of config callback properly for

Subject: mac80211: tear down all agg queues when restart/reconfig hw

When there is a need to restart/reconfig hw, tear down all the
aggregation queues and let the mac80211 and driver get in-sync to have
the opportunity to re-establish the aggregation queues again.

Need to wait until driver re-establish all the station information before tear
down the aggregation queues, driver(at least iwlwifi driver) will reject the
stop aggregation queue request if station is not ready. But also need to make
sure the aggregation queues are tear down before waking up the queues, so
mac80211 will not sending frames with aggregation bit set.

Subject: b43/b43legacy: Wake queues in wireless_core_start

If b43 or b43legacy are deauthenticated or disconnected, there is a
possibility that a reconnection is tried with the queues stopped in
mac80211. To prevent this, start the queues before setting
STAT_INITIALIZED.

In b43, a similar change has been in place (twice) in the
wireless_core_init() routine. Remove the duplicate and add similar
code to b43legacy.

Subject: ssb: fix interrupt assignment

Explicitely enable shared interrupt 2 for any core that didn't get a dedicated IRQ
anymore (fallthrough case) and for EXTIF cores to make gpio interrupts work.
Also remove a bogus comment.

mac80211 uses unit units of 32 usec with txop but wl1251_acx_ac_cfg()
expects it to be usecs. This fortunately didn't cause any severe problems,
only that firmware was using incorrect WMM settings.

Subject: libertas: don't retry commands

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.

Also rename command_timer_fn() into lbs_cmd_timeout_handler(),
which better reflect it's usage.

Subject: iwlwifi: Add chain_noise support for 6050

Existing iwl6050_ops->iwl6050_hcmd_utils structure had no pointers to chain
noise functions (gain_computation and chain_noise_reset).  As it turns out,
by adding chain_noise_scale (see related patch), there is no need for separate
chain noise function, so simply use iwl6000_ops->iwl5000_hcmd_utils, and
remove those for 6050.

Subject: iwlwifi: Send broadcast probe request only when asked to

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Subject: mac80211: fix deauth race

When userspace requests a deauth while the
authentication work is pending in the auth
(not probe) state, we do not properly abort
the work and then things get confused.

Fix that and also improve the checks here
to include the correct virtual interface,
just in case two virtual interfaces would
ever try to connect to the same BSS.

Also fix a bug -- need to use list_del_rcu
instead of just list_del to free a work
item.

Subject: ar9170: remove get_tx_stats() mac80211 op

get_tx_stats() will be removed from mac80211.

Because ar9170 uses ieee80211_tx_queue_stats internally, create a new
identical struct ar9170_tx_queue_stats which the driver can use.

Compile-tested only.

Subject: p54: remove get_tx_stats() mac80211 op

get_tx_stats() will be removed from mac80211.

p54 uses struct ieee80211_tx_queue_stats also internally, so create a new
identical struct p54_tx_queue_stats which the driver can use.

Compile-tested only.

Subject: mac80211: remove get_tx_stats() driver op

get_tx_stats() driver operation is not currently used anywhere in mac80211
and there are no plans to use it in the not-so-near future. So it can go
without anyone missing it.

Subject: mac80211: Reset dynamic ps timer in Rx path.

The current mac80211 implementation enables power save if there
is no Tx traffic for a specific timeout. Hence, PS is triggered
even if there is a continuous Rx only traffic(like UDP) going on.
This makes the drivers to wait on the tim bit in the next beacon
to awake which leads to redundant sleep-wake cycles.
Fix this by restarting the dynamic ps timer on receiving every
data packet.

Subject: mac80211: Retry null data frame for power save.

Even if the null data frame is not acked by the AP, mac80211
goes into power save. This might lead to loss of frames
from the AP.
Prevent this by restarting dynamic_ps_timer when ack is not
received for null data frames.

Subject: netfilter: xtables: compact table hook functions (1/2)

This patch combines all the per-hook functions in a given table into
a single function. Together with the 2nd patch, further
simplifications are possible up to the point of output code reduction.

From 2b21e051472fdb4680076278b2ccf63ebc1cc3bc Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Sat, 13 Jun 2009 06:57:10 +0200
Subject: netfilter: xtables: compact table hook functions (2/2)

The calls to ip6t_do_table only show minimal differences, so it seems
like a good cleanup to merge them to a single one too.
Space saving obtained by both patches: 6807725->6807373
("Total" column from `size -A`.)

Subject: netfilter: xtables: use xt_table for hook instantiation

The respective xt_table structures already have most of the metadata
needed for hook setup. Add a 'priority' field to struct xt_table so
that xt_hook_link() can be called with a reduced number of arguments.

So should we be having more tables in the future, it comes at no
static cost (only runtime, as before) - space saved:
6807373->6806555.

Subject: netfilter: xtables: generate initial table on-demand

The static initial tables are pretty large, and after the net
namespace has been instantiated, they just hang around for nothing.
This commit removes them and creates tables on-demand at runtime when
needed.

Size shrinks by 7735 bytes (x86_64).

Subject: fec: fix uninitialized rx buffer usage

The fec driver was enabling receive buffer descriptor without allocating
the buffers. Make sure the buffer descriptors are initialized to not
start receiving packets.

Open also calls fec_restart after the rx buffers are allocated. With the code
in fec_restart, it zeroes out the buffer descriptors that have just been
setup.

timestamp in probe responses (before this patch, it was
always 0).  Set it correctly when initializing the TX

Subject: sky2: resume clocks

Change the resume path to use pci write config for a couple of reasons:
1. pci_write_config_dword() allows for more error
   checking of PCI health after resume.

2. better to toggle this register on all chip types, since that
   is what vendor driver does.

Subject: sky2: receive checksum refactoring

Break the largish case for handling receive checksum into a separate
function, and if there is a problem use dev_XXX routines to
show which hardware is the problem.

Turn one corner case into a BUG().  This only happens if the driver
is expecting one behavior but the chip does the old behavior;
only ever saw this when bringing up a new chip type and driver
was buggy.

Subject: ethtool: Introduce n-tuple filter programming support

This patchset enables the ethtool layer to program n-tuple
filters to an underlying device.  The idea is to allow capable
hardware to have static rules applied that can assist steering
flows into appropriate queues.

Hardware that is known to support these types of filters today
are ixgbe and niu.

Subject: netfilter: nf_conntrack_sip: fix ct_sip_parse_request() REGISTER
 request parsing

When requests are parsed, the "sip:" part of the SIP URI should be skipped.

Usually this doesn't matter because address parsing skips forward until after
the username part, but in case REGISTER requests it doesn't contain a username
and the address can not be parsed.

Subject: netfilter: nf_conntrack_sip: pass data offset to NAT functions

When using TCP multiple SIP messages might be present in a single packet.
A following patch will parse them by setting the dptr to the beginning of
each message. The NAT helper needs to reload the dptr value after mangling
the packet however, so it needs to know the offset of the message to the
beginning of the packet.

Subject: netfilter: nf_conntrack_sip: add TCP support

Add TCP support, which is mandated by RFC3261 for all SIP elements.

SIP over TCP is similar to UDP, except that messages are delimited
by Content-Length: headers and multiple messages may appear in one
packet.

Subject: netfilter: nf_nat: support mangling a single TCP packet multiple
 times

nf_nat_mangle_tcp_packet() can currently only handle a single mangling
per window because it only maintains two sequence adjustment positions:
the one before the last adjustment and the one after.

This patch makes sequence number adjustment tracking in
nf_nat_mangle_tcp_packet() optional and allows a helper to manually
update the offsets after the packet has been fully handled.

Subject: iwlwifi: multiple force reset mode

Provide the function to perform different type of uCode reset/reload operation.
When uCode detect error and can not fix itself, this iwl_force_reset()
function allow driver to perform the necessary reset/reload functions and help
to bring uCode back to normal operation state.

Currently only 2 type of force reset are available:
 - reset radio
 - reload firmware

Subject: iwlwifi: check for aggregation frame and queue

Error checking for aggregation frames should go into aggregation queue,
if aggregation queue not available, use legacy queue instead.
Also make sure the aggregation queue is available to activate,
if driver and mac80211 is out-of-sync, try to disable the queue and
sync-up with mac80211.

Subject: iwlwifi: fix scan race

There is a problem if an "internal short scan" is in progress when a
mac80211 requested scan arrives. If this new scan request arrives within
the "next_scan_jiffies" period then driver will immediately return success
and complete the scan. The problem here is that the scan has not been
fully initialized at this time (is_internal_short_scan is still set to true
because of the currently running scan), which results in the scan
completion never to be sent to mac80211. At this time also, evan though the
internal short scan is still running the state (is_internal_short_scan)
will be set to false, so when the internal scan does complete then mac80211
will receive a scan completion.

Fix this by checking right away if a scan is in progress when a scan
request arrives from mac80211.

Subject: iwlwifi: reset card during probe

To ensure that card is in a sane state during probe we add a reset call.
This change was prompted by users of kdump who was not able to bring up the
wireless driver in the kdump kernel. The problem here was that the primary
kernel, which is not running at the time, left the wireless card up and
running. When the kdump kernel starts it is thus possible to immediately
receive interrupts from firmware after registering interrupt, but without
being ready to deal with interrupts from firmware yet.

Subject: iwlwifi: Adjusting PLCP error threshold for 1000 NIC

While testing the station with the NIC 1000 family, it is found that
the plcp error can easily exceed 50 value in 100mSecs.  This creates
unneccessary radio reset/tuning.  This patch raises the PLCP error
threshold of the NIC 1000 from 50 to 200 error count.

Subject: iwlwifi: clear all the stop_queue flag after load firmware

All the queues are awake and ready to use after loading firmware,
for firmware reload case, if any queues was stopped before
reload, mac80211 will wake those queues after restart hardware, so make
sure all the flag used to keep track of the queue status are
reset correctly.

Subject: iwlwifi: Monitor and recover the aggregation TX flow failure

This change monitors the tx statistics to detect the drop in throughput.
When the throughput drops, the ratio of the actual_ack_count and the expected_
ack_count also drops.  At the same time, the aggregated ba_timeout (the number
of ba timeout retries) also rises.  If the actual_ack_count/expected_ack_count
ratio is 0 and the number of ba timeout retries rises to 16, no tx packets
(tcp, udp, or ping - icmp) can be delivered.  The driver recovers from this
situation by reseting the uCode firmware.  If the actual_ack_count/expected_
ack_count ratio drops below 50% (but not 0) and the aggregated ba_timeout
retries just exceed 5 (but not 16), then the driver can reset the radio to
bring the throughput up.

Subject: ethtool: Use explicit designated initializers for .cmd

Initialize the .cmd member of various ethtool using a designated struct
initializer rather.  This makes things a teeny bit more robust, although
the chance of a struct layout changing is extremely remote, and also
makes the code a little easier to read.

Subject: ath9k: add a workaround for ack timeout issues

Adding support for setting the coverage class in some cases broke
association and data transfer, as it overwrote the initial ACK timeout
value from the initvals with a smaller value.
I don't know why the new value works in 5 GHz (matches the initval
there), but not in 2.4 GHz (initvals use 64us here), so until the
problem is fully understood, the value should be increased again.

Use "phy_find_first" instead of manual lookup. Also use "phy_connect_direct"
instead of "phy_connect" since we already have phy_device pointer here.

Subject: dccp: allow probing of CCID-array length

This fixes a problem in the DCCP getsockopt() API: currently there is no way
for a user to a priori know the number of built-in CCIDs, other than trying
DCCP_SOCKOPT_AVAILABLE_CCIDS in a loop, incrementing the option length until
EINVAL is no longer returned.

This patch truncates the array to the user-provided length. No copy is made
when the length is <= 0.

Due to the length restriction in do_dccp_getsockopt() to sizeof(int), the
minimum array length remains 4, which is a reasonable default (only 3
CCIDs, CCID-2..4, are currently defined).

Subject: ipv6: fib: fix crash when changing large fib while dumping it

When the fib size exceeds what can be dumped in a single skb, the
dump is suspended and resumed once the last skb has been received
by userspace. When the fib is changed while the dump is suspended,
the walker might contain stale pointers, causing a crash when the
dump is resumed.

Store the serial number when beginning to walk the fib and reload
pointers when continuing to walk after a change occured. Similar
to other dumping functions, this might cause unrelated entries to
be missed when entries are deleted.

Subject: net: move am79c961's probe function to .devinit.text
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A pointer to am79c961_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

Subject: net: Micrel KSZ8841/2 PCI Ethernet driver

This is a new network driver for Micrel KSZ8841/KSZ8842 PCI Ethernet chips.  The same driver can run both chips at the same time.  It supports IPv4 TCP hardware checksumming and so can use scatter/gather transmission.

The KSZ8842 switch has 2 ports.  Some users like to take direct control of those ports.  So KSZ8842 has a multiple devices mode in which the driver creates another network device so that users can specify which port to send packets.  This mode is enabled by passing the "multi_dev=1" parameter to the driver during loading.

The KSZ884X can receive huge frames with size up to 1916 bytes.  To use this feature change the network device MTU from 1500 to 1898.

The KSZ884X driver has 3 packet receive processing functions for the normal mode, multiple devices mode, and huge frame mode.  Those functions are identical except for more checking for the new features.  In normal programming point of view the huge frame version is the one to use because it covers all the cases, but this is done for performance consideration because the target clients for the KSZ884X chips are embedded systems, which unlike desktop PC may not have powerful CPU.

Subject: be2net: fix to limit max vlans supported in certain skews

In certain skews the ASIC can support only 16 vlans per interface.
Once the limit is crossed, the ASIC is programmed in vlan promiscuous mode.
Switch off the vlan promiscuous mode once the number of vlans
falls back to the max vlans supported.

Subject: IPv6: keep permanent addresses on admin down

Permanent IPV6 addresses should not be removed when the link is
set to admin down, only when device is removed.

When link is lost permanent addresses should be marked as tentative
so that when link comes back they are subject to duplicate address
detection (if DAD was enabled for that address).

Other routing systems keep manually configured IPv6 addresses
when link is set down.

Subject: netdevice.h: Add netdev_printk helpers like dev_printk

These netdev_printk routines take a struct net_device * and emit
dev_printk logging messages adding "%s: " ... netdev->dev.parent
to the dev_printk format and arguments.

This can create some uniformity in the output message log.

These helpers should not be used until a successful alloc_netdev.

Subject: drivers/net/atl1e: Use netdev_printk helpers

Logging messages sometimes had duplicated "ATL1E" output.

For instance:
ATL1E 0000:03:00.0: ATL1E: eth0 NIC Link is Up<100 Mbps Full Duplex>
is now:
ATL1E 0000:03:00.0: eth0: NIC Link is Up <100 Mbps Full Duplex>

Add some consistency to logging messages
Add some missing \n's to logging messages
Miscellaneous typo spelling corrections
Change atl1e_validate_option argument from pdev to adapter

Subject: include/linux/netdevice.h: Add netif_printk helpers

Add macros to test a private structure for msg_enable bits
and the netif_msg_##bit to test and call netdev_printk if set

Simplifies logic in callers and adds message logging consistency

Subject: sky2: WoL changes

Change Wake On Lan code to be similar to vendor driver. The definition
of Y2_HW_WOL_ON is confusing; what it means is transition to firmware SPI
setting when doing power change.

Since same code is done for both shutdown and suspend, use common
code path.

Subject: sky2: Allocate initial skbs in sky2_alloc_buffers

Allocate everything in one place so there's a single point
of failure in sky2_up, and sky2_rx_start can no longer fail.

Don't leave the hardware in a partially initialized state in the
case rx ring allocation fails.

As with the old code, the rx ring still needs to be fully
allocated for sky2_up to succeed.

Subject: sky2: Avoid down and up during sky2_reset

Rewrite sky2_reset to work with interrupts disabled and
 avoid freeing and reallocing memory.

The old code used sky2_down and sky2_up to implement sky2_reset,
 which meant interrupts could not be disabled, and the transmit and
 receive ring buffers would be free'd and reallocated.

To avoid the interrupt handler waking the transmit queue while
 we're doing a reset, it's better to have interrupts and NAPI
 polls disabled.

Note: Modified Mike's patch to do IRQ disable in sky2_down before
 calling sky2_hw_down - Stephen

Subject: dccp: support for passing MSG_TRUNC

DCCP is datagram-oriented but lacks UDP's support for MSG_TRUNC as defined in
recvmsg(2)/recv(2). Hence the following 'Hello world\0' receiver

  len = recv(fd, buf, 10, MSG_PEEK | MSG_TRUNC);

wrongly (always) returns 10, while in UDP it returns 12 as expected.
This patch adds the missing MSG_TRUNC support to recvmsg().

Subject: udp: remove redundant variable

The variable 'copied' is used in udp_recvmsg() to emphasize that the passed
'len' is adjusted to fit the actual datagram length. But the same can be
done by adjusting 'len' directly. This patch thus removes the indirection.

Add macros dev_is_pci, dev_is_ps, and dev_num_vf to make it easier for
non-PCI specific code to determine SR-IOV capabilities.

Subject: tg3: Give MSI-X vec 1 rx backlog space

RSS ring 1 is responsible for submitting new rx buffers to the
hardware on behalf of all the other RSS rx return rings.  Up until now
this ring submitted its new rx buffers to the producer ring directly.
The following patch will require that this ring have a place to put
backlogged rx packets.  As a consequence, it can no longer submit new
buffers to the producer ring.

This patch adds code to allocate an extra shadow producer ring for this
RSS ring and adds RSS ring 1 to the list of rings needing buffer
transfers.

Subject: tg3: Prevent rx producer ring overruns

When operating in RSS mode, it is possible for one rx return ring to
submit enough rx buffers back to the hardware such that it inadvertently
overwrites data needed by another rx return ring.  This patch addresses
the problem by looking for non-NULL skb pointers in the
rx_[std|jmb]_buffers rings that parallel the rx producer rings.

Subject: tg3: Unwedge stuck MSI-X vectors

The previous patch changed the code so that new rx buffer submissions to
the hardware stall if a new submission would overwrite data needed by an
unserviced rx packet.  On very busy 5717 and 57765 asic rev devices,
there is a corner case where the hardware will fail to assert an MSI-X
interrupt for rx traffic.  If that vector's interrupt never has another
reason to assert, any rx buffers held will never be serviced.  If the
buffers are never serviced and the hardware consumes all the available
rx packets for other rx rings, deadlock will result.

The most reliable and least intrusive way to work around the problem is
to detect the case where new submissions would overwrite existing data
and force all rx interrupt vectors to fire.

Subject: tg3: Fix 57765 A0 bootcode race condition

On A0 revision of 57765 asic rev devices, the bootcode will perform some
hardware operations, after the magic signature is presented, that will
collide with setup operations performed by the driver.  The best way to
avoid the contention is to have the driver delay an additional 10
milliseconds.  B0 revisions of the chip will make this workaround
unnecessary.

Subject: tg3: Reset phy during bringup when using phylib

The driver puts the phy into low-power mode when it releases the device.
If the device were to be reacquired, the phy needs a reset to bring it
back to full powered operation.  This patch allows phylib-enabled
devices to reset the phy.

Subject: vhost-net: switch to smp barriers

vhost-net only uses memory barriers to control SMP effects
(communication with userspace potentially running on a different CPU),
so it should use SMP barriers and not mandatory barriers for memory
access ordering, as suggested by Documentation/memory-barriers.txt

Subject: mac80211: Fix error introduced in netdev_mc_count() changes.

Commit 4cd24eaf0c6ee7f0242e34ee77ec899f255e66b5
("net: use netdev_mc_count and netdev_mc_empty when appropriate")
added this hunk to net/mac80211/iface.c:

 	__dev_addr_unsync(&local->mc_list, &local->mc_count,
-			  &dev->mc_list, &dev->mc_count);
+			  &dev->mc_list, dev->mc_count);

which is definitely not correct, introduced a warning (reported
by Stephen Rothwell):

net/mac80211/iface.c: In function 'ieee80211_stop':
net/mac80211/iface.c:416: warning: passing argument 4 of '__dev_addr_unsync' makes pointer from integer without a cast
include/linux/netdevice.h:1967: note: expected 'int *' but argument is of type 'int'

and is thus reverted here.

Subject: netfilter: nf_conntrack: pass template to l4proto ->error() handler

The error handlers might need the template to get the conntrack zone
introduced in the next patches to perform a conntrack lookup.

Subject: netfilter: nf_conntrack: add support for "conntrack zones"

Normally, each connection needs a unique identity. Conntrack zones allow
to specify a numerical zone using the CT target, connections in different
zones can use the same identity.

Example:

iptables -t raw -A PREROUTING -i veth0 -j CT --zone 1
iptables -t raw -A OUTPUT -o veth1 -j CT --zone 1

Subject: netfilter: ebtables: abort if next_offset is too small

next_offset must be > 0, otherwise this loops forever.
The offset also contains the size of the ebt_entry structure
itself, so anything smaller is invalid.

Subject: netfilter: ebtables: avoid explicit XT_ALIGN() in match/targets

This will cause trouble once CONFIG_COMPAT support is added to ebtables.
xt_compat_*_offset() calculate the kernel/userland structure size delta
using:

XT_ALIGN(size) - COMPAT_XT_ALIGN(size)

If the match/target sizes are aligned at registration time,
delta is always zero.

Should have zero effect for existing systems: xtables uses
XT_ALIGN() whenever it deals with match/target sizes.

Subject: netfilter: CONFIG_COMPAT: allow delta to exceed 32767

with 32 bit userland and 64 bit kernels, it is unlikely but possible
that insertion of new rules fails even tough there are only about 2000
iptables rules.

This happens because the compat delta is using a short int.
Easily reproducible via "iptables -m limit" ; after about 2050
rules inserting new ones fails with -ELOOP.

Note that compat_delta included 2 bytes of padding on x86_64, so
structure size remains the same.

        mac80211: reduce reliance on netdev

This manifested itself only in debug messages
and in the debugfs rename failure that would
always happen due to trying to rename the dir
over itself.

Subject: nl80211: does not allow NEW_STATION and DEL_STATION for mesh

As discussed in linux-wireless mailing list, adding and removing
stations for mesh topologies is not necessary. Since doing it triggers
bugs, the sugestion was to simply disable it.

Tested using a custom iw command "station new". Works only after using
hostapd. "station del" command also works.

From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Sat, 13 Feb 2010 20:55:48 +0100
Subject: rt2x00: Reorganize RT chipset setting for PCI/SOC devices.

Don't set the RT chipset for a device from within the generic PCI/SOC code,
but rather from the individual drivers, so that individual drivers have
more control over what RT chipset is set.
Preparation for chip handling updates for rt2800 devices.

From 49e721ec6ca74f90ee99089ad2de1c338a95c6d5 Mon Sep 17 00:00:00 2001
From: Gertjan van Wingerde <gwingerde@gmail.com>
Date: Sat, 13 Feb 2010 20:55:49 +0100
Subject: rt2x00: rework RT chipset and revision determination for PCI an SOC
 devices.

The recent rt2800 devices are no longer really identified by their PCI
ID's, but rather by the contents of their CSR0 register. Also for the
other chipsets is the contents of this CSR0 register important.
Change the chipset determination logic to be more aligned with the rt2800
model.
Preparation for the support of rt3070 / rt3090 based devices.

From de1ebdceb6a4fe1b7073b81d273285b7c8bed312 Mon Sep 17 00:00:00 2001

Subject: rt2x00: rt2800 - Make rt30xx and rt35xx chipsets configurable.

Support for rt30xx- and rt35xx-based devices is currently not functional
in rt2800pci and rt2800usb.
In order to not confuse users we shouldn't claim the PCI and USB device
ID's for these devices. However, to allow for testing it is good to still
have them available, although disabled by default.
Make support for these device configuration options that default to off.

For rt2800usb a 3rd class of devices is added, which are the unknown
devices. For these devices it is known that they are either based on
rt28xx, rt30xx or rt35xx, but it is not known on what chipset exactly.
These devices are disabled by default as well, until it can be established
on what chipset exactly they are based.

Subject: mac80211: reject unhandled action frames

802.11-2007 7.3.1.11 mandates that we need to
reject action frames we don't handle by setting
the 0x80 bit in the category and returning them
to the sender, so do that. In AP mode, hostapd
is responsible for this.

Additionally, drop completely malformed action
frames or ones that should've been encrypted as
unusable, userspace shouldn't see those.

From: Jouni Malinen <jouni.malinen@atheros.com>

Subject: cfg80211/mac80211: allow registering for and sending action frames

This implements a new command to register for action frames
that userspace wants to handle instead of the in-kernel
rejection. It is then responsible for rejecting ones that
it decided not to handle. There is no unregistration, but
the socket can be closed for that.

Frames that are not registered for will not be forwarded
to userspace and will be rejected by the kernel, the
cfg80211 API helps implementing that.

Additionally, this patch adds a new command that allows
doing action frame transmission from userspace. It can be
used either to exchange action frames on the current
operational channel (e.g., with the AP with which we are
currently associated) or to exchange off-channel Public
Action frames with the remain-on-channel command.

The code is however broken, the driver does not check the link fault

The link fault status being checked within a short period of time,
it leads to link up/link down events.

Subject: net/macvtap: fix reference counting

The RCU usage in the original code was broken because
there are cases where we possibly sleep with rcu_read_lock
held. As a fix, change the macvtap_file_get_queue to
get a reference on the socket and the netdev instead of
taking the full rcu_read_lock.

Also, change macvtap_file_get_queue failure case to
not require a subsequent macvtap_file_put_queue, as
pointed out by Ed Swierk.

Subject: IPv6: Delete redundant counter of IPSTATS_MIB_REASMFAILS

When no more memory can be allocated, fq_find() will return NULL and
increase the value of IPSTATS_MIB_REASMFAILS. In this case,
ipv6_frag_rcv() also increase the value of IPSTATS_MIB_REASMFAILS.

So, the patch deletes redundant counter of IPSTATS_MIB_REASMFAILS in fq_find().
and deletes the unused parameter of idev.

Subject: xfrm: Flushing empty SAD generates false events

To see the effect make sure you have an empty SAD.
-On window1 "ip xfrm mon"
-on window2 issue "ip xfrm state flush"
You get prompt back in window1
and you see the flush event on window2.
With this fix, you still get prompt on window1 but no
event on window2.

I was tempted to return -ESRCH on window1 (which would
show "RTNETLINK answers: No such process") but didnt want
to change current behavior.

cheers,
jamal

    xfrm: Flushing empty SPD generates false events

    To see the effect make sure you have an empty SPD.
    On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush"
    You get prompt back in window1 and you see the flush event on window2.
    With this fix, you still get prompt on window1 but no event on window2.

Subject: ethtool: reduce stack usage

dev_ethtool() is currently using 604 bytes of stack, even with gcc-4.4.2

objdump -d vmlinux | scripts/checkstack.pl
...
0xc04bbc33 dev_ethtool [vmlinux]:			604
...
Adding noinline attributes to selected functions can reduce stack usage.

Subject: netfilter: ebtables: split do_replace into two functions

once CONFIG_COMPAT support is merged this allows
to call do_replace_finish() after doing the CONFIG_COMPAT conversion
instead of copy & pasting this.

Subject: netfilter: ebtables: split copy_everything_to_user into two functions

once CONFIG_COMPAT support is added to ebtables, the new
copy_counters_to_user function can be called instead of duplicating
code.

Also remove last use of MEMPRINT, as requested by Bart De Schuymer.

Subject: netfilter: ebtables: add CONFIG_COMPAT support

Main code for 32 bit userland ebtables binary with 64 bit kernels
support.

Tested on x86_64 kernel only, using 64bit ebtables binary
for output comparision.

At least ebt_mark, m_mark and ebt_limit need CONFIG_COMPAT hooks, too.

remaining problem:

The ebtables userland makefile has:
ifeq ($(shell uname -m),sparc64)
	CFLAGS+=-DEBT_MIN_ALIGN=8 -DKERNEL_64_USERSPACE_32
endif

struct ebt_replace, ebt_entry_match etc. then contain userland-side
padding, i.e.  even if we are called from a 32 bit userland, the
structures may already be in the right format.

This problem is addressed in a follow-up patch.

Subject: netfilter: ebtables: try native set/getsockopt handlers, too

ebtables can be compiled to perform userspace-side padding of
structures. In that case, all the structures are already in the
'native' format expected by the kernel.

This tries to determine what format the userspace program is
using.

For most set/getsockopts, this can be done by checking
the len argument for sizeof(compat_ebt_replace) and
re-trying the native handler on error.

In case of EBT_SO_GET_ENTRIES, the native handler is tried first,
it will error out early when checking the *len argument
(the compat version has to defer this check until after
 iterating over the kernel data set once, to adjust for all
 the structure size differences).

As this would cause error printks, remove those as well, as
recommended by Bart de Schuymer.

ebt_limit structure is larger on 64 bit systems due

Setting .compatsize is enough in this case, these values

Currently, ieee80211_drop_unencrypted is called
from management and data frame context, and the
different contexts pass different frames. This
could lead to it processing an 802.3 frame as an
802.11 frame when MFP is enabled.

Move the MFP part of ieee80211_drop_unencrypted
into a new function that is only called for mgmt
frames.

Subject: gre: fix netns vs proto registration ordering

GRE protocol receive hook can be called right after protocol addition is done.
If netns stuff is not yet initialized, we're going to oops in
net_generic().

This is remotely oopsable if ip_gre is compiled as module and packet
comes at unfortunate moment of module loading.

Subject: atl1c: Add support for Atheros AR8152 and AR8152

AR8151 is a Gigabit Ethernet device. AR8152 devices are
Fast Ethernet devices, there are two revisions, a 1.0
and a 2.0 revision.

This has been tested against these devices:

Driver	Model-name	vendor:device	Type
atl1c 	AR8131		1969:1063	Gigabit Ethernet
atl1c	AR8132		1969:1062	Fast Ethernet
atl1c	AR8151(v1.0)	1969:1073	Gigabit Ethernet
atl1c	AR8152(v1.1)	1969:2060	Fast Ethernet

This device has no hardware available yet so it goes untested,
but it should work:

atl1c	AR8152(v2.0)	1969:2062	Fast Ethernet

Checking the flag is more correct than checking bp->irq_nvecs. By
accident it is not a problem because we always have more than 1
vectors when using MSIX mode.

Subject: bnx2: Allow user-specified multiple advertisement speed values.

Remove unnecessary code that works around older versions of ethtool
that can pass down invalid advertisement speed values.  This old
code prevents the user from specifying multiple advertisement values.
The new code uses simple masking to mask out invalid advertisment bits.

Subject: net ipv4: Decouple ipv4 interface parameters from binary sysctl
 numbers

Stop using the binary sysctl enumeartion in sysctl.h as an index into
a per interface array.  This leads to unnecessary binary sysctl number
allocation, and a fragility in data structure and implementation
because of unnecessary coupling.

Subject: net neigh: Decouple per interface neighbour table controls from
 binary sysctls

Stop computing the number of neighbour table settings we have by
counting the number of binary sysctls.  This behaviour was silly
and meant that we could not add another neighbour table setting
without also adding another binary sysctl.

Don't pass the binary sysctl path for neighour table entries
into neigh_sysctl_register.  These parameters are no longer
used and so are just dead code.

Instead of looking up the dentry of an NCCI node again in
capifs_free_ncci pass the pointer via the capifs user.

This patch also reduces the #ifdef mess in capi.c a bit as far as capifs
was causing it.

Subject: CAPI: Pin capifs instead of mounting it

Auto-mounting the capifs during module init prevents unloading its
module. Instead, pin the filesystem as long as some NCCI node exists.

Subject: CAPI: Reduce chattiness during module loading/removal

The CVS revisions dumped by all CAPI modules are meaningless today. And
that some CAPI module is loaded or removed does not necessarily deserve
a message. Just keep the message of the central module, capi.ko, drop
the rest.

Subject: CAPI: Rework capi_ctr_ready/down

This step prepares the application of proper controller locking: Push
all state changing work into the notify handler that are called by
capi_ctr_ready and capi_ctr_down, switch detach_capi_ctr to issue a
synchronous ctr_down. Also ensure that we do not go through any action
if the state did not change.

Subject: CAPI: Rework controller state notifier

Another step towards proper locking: Rework the callback provided to
capidrv for controller state changes. This is so far attached to an
application, which would require us to hold the corresponding lock
across notification calls.

But there is no direct relation between a controller up/down event and
an application, so let's decouple them and provide a notifier call chain
for those events instead. This notifier chain is first of all used
internally. Here we request the highest priority to unsure that
housekeeping work is done before any other notifications. The chain is
exported via [un]register_capictr_notifier to our only user, capidrv, to
replace the racy and unfixable capi20_set_callback.

From 0ca3a017a7373a4545dd7b345a8a0cecc16bc7e2 Mon Sep 17 00:00:00 2001
From: Jan Kiszka <jan.kiszka@web.de>

Subject: CAPI: Rework locking of controller data structures

This patch applies the mutex so far only protecting the controller list
to (almost) all accesses of controller data structures. It also reworks
waiting on state changes in old_capi_manufacturer so that it no longer
poll and holds a module reference to the controller owner while waiting
(the latter was partly done already). Modification and checking of the
blocked state remains racy by design, the caller is responsible for
dealing with this.

Subject: CAPI: Rework application locking

Drop the application rw-lock in favour of RCU. This synchronizes
capi20_release against capi_ctr_handle_message which may dereference an
application from (soft-)IRQ context. Any other access to the application
list is now protected by the capi_controller_lock as well. This also
allows to safely inspect applications for /proc dumping by holding
capi_controller_lock.

At this chance, drop some useless release_in_progress checks where we
obtained the application pointer from the list (which becomes NULL on
release_in_progress).

Subject: CAPI: Reduce #ifdef mess around CONFIG_ISDN_CAPI_MIDDLEWARE

Make the code a bit more readable be providing stub functions for the
!CONFIG_ISDN_CAPI_MIDDLEWARE case. Though a few lines are moved around,
this comes with no functional changes.

Subject: CAPI: Convert capidev_list_lock into a mutex

No need for anything "harder" here (specifically no need for
irqsave...). Also, make the list removal the first operation of
capidev_free to avoid dumping half-released devices via /proc.

Subject: CAPI: Clean up capi_open/release

Fold capidev_alloc and capidev_free into capi_open and capi_release -
there are no other users. Someone pushed a lock_kernel into capi_open.
Drop it, we don't need it. Also remove the useless test from open that
checks for private_data == NULL.

Subject: CAPI: Rework locking of capidev members

Rename 'ncci_list_mtx' to 'lock', expressing that it now protects a
larger set of capidev members: the NCCI list, ap.applid (ie. the
registration of the application), and modifications of userflags.

We do not need to protect each and every check for ap.applid because,
once an application is registered, it will stay for the whole lifetime
of the device.

Also, there is no need to apply the capidev mutex during release (if
there could be concurrent users, we would crash them anyway by freeing
the device at the end of capi_release).

Return proper error code if tty_register_driver fails. In contrast,
tty_unregister_driver cannot practically fail, so drop that error
handling. Finally, mark capinc_tty_init/exit with __init/__exit.

Subject: CAPI: Dynamically register minor devices

Register capiminors dynamically with the TTY core so that udev can make
them show up as the NCCIs appear or disappear. This removes the need to
check if the capiminor requested in capinc_tty_open actually exists.

And this completely obsoletes capifs which will be scheduled for removal
in a later patch.

Subject: CAPI: Use kref on capiminor

Install a reference counter for capiminor objects. Acquire it when
obtaining a capiminor from the array during capinc_tty_open, drop it
when closing the tty again. Another reference is held for the hook-up
with capincci.

Subject: CAPI: Issue synchronous hangup on capincci_free_minor

capincci_free and, thus, capincci_free_minor runs in process context, so
we can issue the hangup of the associated TTY synchronously.

The nccip in capiminor used to serve as an indicator that the NCCI was
close. But we don't need this, we issue a hangup on capincci_free_minor.
So drop this legacy.

Subject: CAPI: Fix locking around capiminor's output queue and drop
 workaround_lock

Introduce outlock as a spin lock that protects capiminor's outqueue,
outbytes and outskb (formerly known as ttyskb). outlock can be acquired
from soft-IRQ context via capinc_write, so make it bh-safe.

This finally removes the last reason for keeping the workaround lock
around (which was incomplete and partly broken anyway). And as we no
longer call handle_recv_skb in atomic context, gen_data_b3_resp_for can
use non-atomic allocation now.

Subject: CAPI: Clean up capiminor_*_ack

No need for irqsave acquisition of acklock, bh-safe is sufficient.
Moverover, move kfree out of the lock and do not take acklock at all
in capiminor_del_all_ack as we are the last user of the list here.

Subject: CAPI: Drop special controller lookup from capi20_put_message

This strange special rule to fall back to controller 1 cannot be derived
from the CAPI specs and looks a lot like it was once dedicated to some
out-of-tree driver, probably AVM's broken fcdsl2 (FRITZ!Card DSL v2.0).
I found no in-tree user that needs this check, and I'm now taking care
of the fcdsl2. So drop these bits from our stack.

With dynamic TTY nodes and the help of udev, we no longer need this

As a last duty to this feature, move its help to right option so that

Despite all its bugs, the middleware support of our CAPI stack was
already in use for many, many moons. And after going through its code,
fixing all issues I found, I feel it deserves to officially become a
non-experimental feature.

Eric's version fixed it for pfkey. This one is for xfrm user.
I thought about amortizing those two get_acqseq()s but it seems
reasonable to have two of these sequence spaces for the two different
interfaces.

Subject: percpu: add __percpu sparse annotations to net

Add __percpu sparse annotations to net.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.

The macro and type tricks around snmp stats make things a bit
interesting.  DEFINE/DECLARE_SNMP_STAT() macros mark the target field
as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly.  All
snmp_mib_*() users which used to cast the argument to (void **) are
updated to cast it to (void __percpu **).

Subject: percpu: add __percpu sparse annotations to net drivers

Add __percpu sparse annotations to net drivers.

These annotations are to make sparse consider percpu variables to be
in a different address space and warn if accessed without going
through percpu accessors.  This patch doesn't affect normal builds.

Subject: igb: remove unecessary q_vector declarations and remove itr_shift

This change removes the use of itr_shift since a mac type call can be
used just as easily to identify the only HW that needs to have the itr
shifted.

In addition it removes two unecessary declarations of a q_vector
pointer from the initialization path.

With this change ethtool will correctly report link status when
the interface is down. Currently ethtool reports the link as not
detected when the interface is down.

Subject: igb: ignore EEPROM APME check when shutting down serdes link

Checking the EEPROM APME state unnecessarily prevents the link from
shutting down. The standard power down routines should be
sufficient to determine whether the serdes link can power down
when going into D3.

Subject: igb: call pci_save_state after pci_restore_state

This patch adds calls to pci_save_state() immediately after
calls to pci_restore_state(). Due to a change in the behavior
of pci_restore_state() it is necessary to call pci_save_state()
to keep the state_saved flag. This patch is based on a similar
patch for ixgbe.

Subject: igb: Allocate rings seperately instead of as a block

This change makes it so that the rings are allocated seperately.  As a
result we can allocate them on seperate nodes at some point in the future
if we so desire.

Subject: igb: remove adaptive IFS from driver

Adaptive IFS support has been included in the igb driver since its
initial release, but it is not a feature on any igb NICs. This patch
removes it from the driver.

Subject: igb: change descriptor control thresholds

This change simplifies the code by setting RX_PTHRESH to 8 for
all devices, as it was unlikely that there was any advantage to
set it at 16 for earlier cards. Additionally TX_WTHRESH is
set to 1 for the 82576 NIC to improve performance by enabling
a minimal amount of write combining when writing back descriptors.

Subject: be2net: don't rearm mcc cq when device is not open

When an MCC cmd is issued (via a netdev/ethtool op)
while the device is not open, the MCC CQ gets processed but the EQ
is not processed (as isr is not registered.) This can cause the EQ
to become full. So, while the device is not open, CQ must not be re-armed
to prevent EQ entries.

From 60b86755929e1a7e9038c8d860a8491cfdf8d93a Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Wed, 17 Feb 2010 10:30:23 +0000
Subject: usbnet: Convert dev(dbg|err|warn|info) macros to netdev_<level>

These macros are too similar to the dev_<level> equivalents
but take a usbnet * argument.  Convert them to the recently
introduced netdev_<level> macros and remove the old macros.

The old macros had "\n" appended to the format string.
Add the "\n" to the converted uses.

Some existing uses of the dev<foo> macros in cdc_eem.c
probably mistakenly had trailing "\n".  No "\n" added there.

Fix net1080 this/other log message inversion.

Subject: drivers/net/usb: Use netif_<level> logging facilities

Convert from:
	if (netif_msg_<foo>(priv))
		dev_<level>(dev...
to
	netif_<level>(priv, foo, dev...

Also convert a few:

	if (i < REG_TIMEOUT) {
		etc...
		return ret;
       }
to
	if (i >= REG_TIMEOUT)
		goto fail;
	etc...
	return ret;

Subject: ethtool: Don't flush n-tuple list from ethtool_reset()

The n-tuple list should be flushed if and only if the ETH_RESET_FILTER
flag is set and the driver is able to reset filtering/flow direction
hardware without also resetting a component whose flag is not set.
This test is best left to the driver.

Subject: xfrm: Revert false event eliding commits.

As reported by Alexey Dobriyan:

--------------------
setkey now takes several seconds to run this simple script
and it spits "recv: Resource temporarily unavailable" messages.

#!/usr/sbin/setkey -f
flush;
spdflush;

add A B ipcomp 44 -m tunnel -C deflate;
add B A ipcomp 45 -m tunnel -C deflate;

spdadd A B any -P in ipsec
        ipcomp/tunnel/192.168.1.2-192.168.1.3/use;
spdadd B A any -P out ipsec
        ipcomp/tunnel/192.168.1.3-192.168.1.2/use;
--------------------

Obviously applications want the events even when the table
is empty.  So we cannot make this behavioral change.

Subject: ipg: Remove device claimed by dl2k from pci id table

This patch removes D-Link DGE-550T PCI ID (1186:4000) from the ipg
driver. The ipg driver is for IP2000-based cards and the DGE-550T is
a DL2000-based card. The driver loads and works for a few moments, but
once a real workload is applied it stops operating. The ipg driver
claimed this ID since it was introduced in 2.6.24 and it's forced many
users to blacklist it.

The correct driver for this hardware is the dl2k driver, which has been
claiming this PCI ID since the 2.4 days.

Subject: net: bug fix for vlan + gro issue

Traffic (tcp) doesnot start on a vlan interface when gro is enabled.
Even the tcp handshake was not taking place.
This is because, the eth_type_trans call before the netif_receive_skb
in napi_gro_finish() resets the skb->dev to napi->dev from the previously
set vlan netdev interface. This causes the ip_route_input to drop the
incoming packet considering it as a packet coming from a martian source.

I could repro this on 2.6.32.7 (stable) and 2.6.33-rc7.
With this fix, the traffic starts and the test runs fine on both vlan
and non-vlan interfaces.

Subject: tg3: Enforce DMA mapping / skb assignment ordering

Michael Chan noted that there is nothing in the code that would prevent
the compiler from delaying the access of the "mapping" member of the
newly arrived packet until much later.  If this happened after the
skb = NULL assignment, it is possible for the driver to pass a bad
dma_addr value to pci_unmap_single().  To enforce this ordering, we need
a write memory barrier.  The pairing read memory barrier already exists
in tg3_rx_prodring_xfer() under the comments starting with
"Ensure that updates to the...".

Subject: tg3: Rename TG3_FLG3_RGMII_STD_IBND_DISABLE

The STD part of this preprocessor definition is a bit of a misnomer.
This flag is a coarse control of the RGMII inband status facilities.
This patch renames the definition to be more accurate.

From 79eb6904361fe4e54e589919a9b62c5e036c42c3 Mon Sep 17 00:00:00 2001

Subject: tg3: Rename tg3 phy ID preprocessor definitions

The phylib presents the phy ID in a different format than the one tg3
has traditionally used.  To highlight the distinction, this patch
prepends the tg3 native phy ID format with TG3.

From: Joe Perches <joe@perches.com>
Date: Wed, 17 Feb 2010 15:01:49 +0000
Subject: drivers/net/8139too.c: Use (pr|netdev|netif)_<level> macro helpers

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Remove #define PFX
Use pr_<level>
Use netdev_<level>
Use netif_<level>
Convert formats like %8.8 to %08
Remove periods from formats
Coalesce long formats
Use print_hex_dump

From: Joe Perches <joe@perches.com>
Date: Wed, 17 Feb 2010 15:01:52 +0000
Subject: drivers/net/bnx2x: Use (pr|netdev|netif)_<level> macro helpers

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Convert struct bnx2x member msglevel to msg_enable for netif_msg_<foo> macros
Remove #define PFX
Use pr_<level>
Use netdev_<level>
Use netif_<level>
Coalesce long formats

Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Remove #define PFX
Use pr_<level>
Use netdev_<level>
Use netif_<level>
Checkpatch cleaning
Convert formats like 0x%08x to %#08x
Remove periods from formats
Coalesce long formats
Use print_hex_dump

Subject: ipvs: SCTP Trasport Loadbalancing Support

Enhance IPVS to load balance SCTP transport protocol packets. This is done
based on the SCTP rfc 4960. All possible control chunks have been taken
care. The state machine used in this code looks some what lengthy. I tried
to make the state machine easy to understand.

Subject: netfilter: nf_defrag_ipv4: fix compilation error with NF_CONNTRACK=n

As reported by Randy Dunlap <randy.dunlap@oracle.com>, compilation
of nf_defrag_ipv4 fails with:

include/net/netfilter/nf_conntrack.h:94: error: field 'ct_general' has incomplete type
include/net/netfilter/nf_conntrack.h:178: error: 'const struct sk_buff' has no member named 'nfct'
include/net/netfilter/nf_conntrack.h:185: error: implicit declaration of function 'nf_conntrack_put'

net/ipv4/netfilter/nf_defrag_ipv4.c:45: error: 'struct sk_buff' has no member named 'nfct'
net/ipv4/netfilter/nf_defrag_ipv4.c:46: error: 'struct sk_buff' has no member named 'nfct'

net/nf_conntrack.h must not be included with NF_CONNTRACK=n, add a
few #ifdefs. Long term the header file should be fixed to be usable
even with NF_CONNTRACK=n.

Subject: macvtap: rework object lifetime rules

This reworks the change done by the previous patch
in a more complete way.

The original macvtap code has a number of problems
resulting from the use of RCU for protecting the
access to struct macvtap_queue from open files.

This includes
- need for GFP_ATOMIC allocations for skbs
- potential deadlocks when copy_*_user sleeps
- inability to work with vhost-net

Changing the lifetime of macvtap_queue to always
depend on the open file solves all these. The
RCU reference simply moves one step down to
the reference on the macvlan_dev, which we
only need for nonblocking operations.

Subject: net/macvtap: add vhost support

This adds support for passing a macvtap file descriptor into
vhost-net, much like we already do for tun/tap.

Most of the new code is taken from the respective patch
in the tun driver and may get consolidated in the future.

From b9fb9ee07e67fce0b7bfd517a48710465706c30a Mon Sep 17 00:00:00 2001
From: Arnd Bergmann <arnd@arndb.de>
Date: Thu, 18 Feb 2010 05:48:17 +0000
Subject: macvtap: add GSO/csum offload support

Added flags field to macvtap_queue to enable/disable processing of
virtio_net_hdr via IFF_VNET_HDR. This flag is checked to prepend virtio_net_hdr
in the receive path and process/skip virtio_net_hdr in the send path.

Original patch by Sridhar, further changes by Arnd.

Subject: tulip: convert to use netdev_for_each_mc_addr

also bug in de2104x.c was corrected:
for (i = 0; i < 32; i++) loop should be outside mc_list iteration.

+Thin-streams and TCP
+====================
+A wide range of Internet-based services that use reliable transport
+protocols display what we call thin-stream properties. This means
+that the application sends data with such a low rate that the
+retransmission mechanisms of the transport protocol are not fully
+effective. In time-dependent scenarios (like online games, control
+systems, stock trading etc.) where the user experience depends
+on the data delivery latency, packet loss can be devastating for
+the service quality. Extreme latencies are caused by TCP's
+dependency on the arrival of new data from the application to trigger
+retransmissions effectively through fast retransmit instead of
+waiting for long timeouts.
+
+After analysing a large number of time-dependent interactive
+applications, we have seen that they often produce thin streams
+and also stay with this traffic pattern throughout its entire
+lifespan. The combination of time-dependency and the fact that the
+streams provoke high latencies when using TCP is unfortunate.
+
+In order to reduce application-layer latency when packets are lost,
+a set of mechanisms has been made, which address these latency issues
+for thin streams. In short, if the kernel detects a thin stream,
+the retransmission mechanisms are modified in the following manner:
+
+1) If the stream is thin, fast retransmit on the first dupACK.
+2) If the stream is thin, do not apply exponential backoff.
+
+These enhancements are applied only if the stream is detected as
+thin. This is accomplished by defining a threshold for the number
+of packets in flight. If there are less than 4 packets in flight,
+fast retransmissions can not be triggered, and the stream is prone
+to experience high retransmission latencies.
+
+Since these mechanisms are targeted at time-dependent applications,
+they must be specifically activated by the application using the
+TCP_THIN_LINEAR_TIMEOUTS and TCP_THIN_DUPACK IOCTLS or the
+tcp_thin_linear_timeouts and tcp_thin_dupack sysctls. Both
+modifications are turned off by default.
+
+References
+==========
+More information on the modifications, as well as a wide range of
+experimental data can be found here:

+reliable transport"

Subject: net: TCP thin linear timeouts

This patch will make TCP use only linear timeouts if the
stream is thin. This will help to avoid the very high latencies
that thin stream suffer because of exponential backoff. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin. A maximum of 6 linear
timeouts is tried before exponential backoff is resumed.

This patch enables fast retransmissions after one dupACK for
TCP if the stream is identified as thin. This will reduce
latencies for thin streams that are not able to trigger fast
retransmissions due to high packet interarrival time. This
mechanism is only active if enabled by iocontrol or syscontrol
and the stream is identified as thin.

be2net: free tx buffers when completions never arrive

In cases like when a pci device is disconnected on an error,
pending tx completions will never arrive. Unmap and free such
buffers in the tx cleanup path.

Subject: Orphan DECnet

Due to lack of time, space, motivation, hardware and probably expertise,
I have reluctantly decided to orphan the DECnet code in the kernel.

Judging by the deafening silence on the linux-decnet mailing list I
suspect it's either not being used anyway, or the few people that are
using it are happy with their older kernels.

Commit 2249065 ("netfilter: get rid of the grossness in netfilter.h")
inverted the logic for conditional hook invocation, breaking the
POST_ROUTING hook invoked by ip_output().

Correct the logic and remove an unnecessary initialization.

Subject: netfilter: ctnetlink: fix creation of conntrack with helpers

This patch fixes a bug that triggers an assertion if you create
a conntrack entry with a helper and netfilter debugging is enabled.
Basically, we hit the assertion because the confirmation flag is
set before the conntrack extensions are added. To fix this, we
move the extension addition before the aforementioned flag is
set.

This patch also removes the possibility of setting a helper for
existing conntracks. This operation would also trigger the
assertion since we are not allowed to add new extensions for
existing conntracks. We know noone that could benefit from
this operation sanely.

Thanks to Eric Dumazet for initial posting a preliminary patch
to address this issue.

Subject: netfilter: nf_conntrack_reasm: properly handle packets fragmented
 into a single fragment

When an ICMPV6_PKT_TOOBIG message is received with a MTU below 1280,
all further packets include a fragment header.

Unlike regular defragmentation, conntrack also needs to "reassemble"
those fragments in order to obtain a packet without the fragment
header for connection tracking. Currently nf_conntrack_reasm checks
whether a fragment has either IP6_MF set or an offset != 0, which
makes it ignore those fragments.

Remove the invalid check and make reassembly handle fragment queues
containing only a single fragment.

Subject: Introduce PCMCIA_DEVICE_PROD_ID3

...and use it in hostap_cs and orinoco_cs.

Another PCMCIA device with Intersil Prism chipset has been reported:

Socket 0:
  product info: "Gigabyte", "GN-WLM01_P25L_ADAPTER", "ISL37300P", "Eval-RevA"
  manfid: 0x02e0, 0x1011
  function: 6 (network)

As it's the case with some other Prism based devices, the third ID
string contains a design name that should be sufficient to identify the
card as having Intersil Prism chipset and thus compatible with both
orinoco_cs and hostap_cs.

Introduce PCMCIA_DEVICE_PROD_ID3 that matches the third ID string only.

Use it in orinoco_cs and hostap_cs to match cards with the third ID
string indicating Prism chipset.  Remove corresponding entries that use
PCMCIA_DEVICE_PROD_ID123.

Subject: nl80211: add power save commands

The most needed command from nl80211, which Wireless Extensions had,
is support for power save mode. Add a simple command to make it possible
to enable and disable power save via nl80211.

I was also planning about extending the interface, for example adding the
timeout value, but after thinking more about this I decided not to do it.
Basically there were three reasons:

Firstly, the parameters for power save are very much hardware dependent.
Trying to find a unified interface which would work with all hardware, and
still make sense to users, will be very difficult.

Secondly, IEEE 802.11 power save implementation in Linux is still in state
of flux. We have a long way to still to go and there is no way to predict
what kind of implementation we will have after few years. And because we
need to support nl80211 interface a long time, practically forever, adding
now parameters to nl80211 might create maintenance problems later on.

Third issue are the users. Power save parameters are mostly used for
debugging, so debugfs is better, more flexible, interface for this.
For example, wpa_supplicant currently doesn't configure anything related
to power save mode. It's better to strive that kernel can automatically
optimise the power save parameters, like with help of pm qos network
and other traffic parameters.

Later on, when we have better understanding of power save, we can extend
this command with more features, if there's a need for that.

Subject: staging: rtl8192su: fix compile error from wireless-testing commit

In wireless-testing, commit 7044cc56 added struct ieee80211_hdr_3addr
to include/linux/ieee80211.h. This definition collides with one that is
in the rtl8192su driver in staging.

The conflict is resolved by changing rtl8192su
to use the definition from include/linux/ieee80211.h.

Subject: wl1271: Fix PSM entry

Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and
beacon filtering to be illegally enabled (because FW remains in active state.)

Fix this by enabling ELP, BET and beacon filtering only after successful entry,
and by ensuring the firmware is in active mode after the failure.

channel change, breaking connectivity, and b) not update the channel number
at all for ad-hoc, breaking adhoc.

Subject: wl1271: Add SSID configuration for JOIN in ad-hoc

This patch adds code to extract the SSID from the beacon template used for
ad-hoc. The mac80211 currently does not provide the SSID, so this is a
workaround for that, for now.

Subject: wl1271: modify wl1271_acx_tid_cfg() to use function parameters

For WMM we need to configure each tid separately so modify
wl1271_acx_tid_cfg() to take the configuration from function parameters
instead.

Subject: wl1271: implement WMM

Now that necessary commands for WMM are implemented, implement queue handling
for WMM. But WMM is not enabled yet, only one queue is used.

Based on a similar patch from wl1251.

Subject: wl1271: Retrieve device mac address from the nvs file

Instead of always randomizing the MAC address, retrieve and configure the
MAC address from the device specific nvs file. For now, randomize an address
only if the address in the NVS is zero.

Subject: wl1271: add most of the normal initialization commands to PLT mode

We need to configure PLT mode almost in the same way as normal mode.  Most of
the configuration functions need to be called also when entering PLT, with
the exception of a few RX and TX configuration (which cause mac80211 warnings
if enable while runnning PLT tests).

If reverting to a random MAC address, the driver would not update it to the

So update the randomized MAC address to the NVS image.

Subject: wl1271: Fix WEP key handling

WEP key index handling was broken: the default key when using key 0 was never
specified to the FW, and if using other default than 0, it would be set on the
TX path for every single TX'd frame.

Subject: wl1271: Fix ad-hoc SSID update

If re-configuring the SSID while ad-hoc was already enabled, the beacon
template would be properly updated, but the SSID passed in the CMD_JOIN would
not - hence filtering etc would not work properly.

Subject: ath9k: fix rate control fallback rate selection

When selecting the tx fallback rate, rc.c used a separate variable
'nrix' for storing the next rate index, however it did not use that as
reference for further rate index lowering. Because of that, it ended up
reusing the same rate for multiple multi-rate retry stages, thus
decreasing delivery probability under changing link conditions.

This patch removes the separate (unnecessary) variable and fixes
fallback the way it was intended to work.
This should result in increased throughput and better link stability.

Subject: iwl3945: remove STATUS macros from header

iwl3945 includes iwl-core.h in which these STATUS flags are already
defined. This also removes a potential confusing definition with iwlcore
using STATUS_MODE_PENDING with value 18 and iwl3945 defining (but not
using) STATUS_CONF_PENDING for value 18.

Subject: iwlwifi: enable serialization of synchronous commands

Until now it was only possible to have one synchronous command running at
any time. If a synchronous command is in progress when a second request
arrives then the second command will fail. Create a new mutex specific for
this purpose to only allow one synchronous command at a time, but enable
other commands to wait instead of fail if a synchronous command is in
progress.

Subject: iwlwifi: separated time check for different type of force reset

Use different timing duration check for different type of force reset,
force reset request can come from different source and based on
different reason; one type of reset request should not block other type of
reset request.

Adding structure to keep track of different force reset request.

Subject: ath9k: fix beacon timer restart after a card reset

In AP mode, ath_beacon_config_ap only restarts the timer if a TSF
restart is requested. Apparently this was added, because this function
unconditionally sets the flag for TSF reset.

The problem with this is, that ath9k_hw_reset() clobbers the timer
registers (specified in the initvals), thus effectively disabling the
SWBA interrupt whenever a card reset without TSF reset is issued
(happens in a few places in the code).

This patch fixes ath_beacon_config_ap to only issue the TSF reset flag
when necessary, but reinitialize the timer unconditionally. Tests show,
that this is enough to keep the SWBA interrupt going after a call to
ath_reset()

Subject: pfkey: fix SA and SP flush sequence

RFC 2367 says flushing behavior should be:
1) user space -> kernel: flush
2) kernel: flush
3) kernel -> user space: flush event to ALL listeners

This is not realistic today in the presence of selinux policies
which may reject the flush etc. So we make the sequence become:
1) user space -> kernel: flush
2) kernel: flush
3) kernel -> user space: flush response to originater from #1
4) if there were no errors then:
kernel -> user space: flush event to ALL listeners

Subject: xfrm: Flushing empty SAD generates false events

To see the effect make sure you have an empty SAD.
On window1 "ip xfrm mon" and on window2 issue "ip xfrm state flush"
You get prompt back in window2 and you see the flush event on window1.
With this fix, you still get prompt on window1 but no event on window2.

Thanks to Alexey Dobriyan for finding a bug in earlier version
when using pfkey to do the flushing.

removed fill_multicast_tbl function in smc91c92_cs and do the work inline

rewritten set_addresses function in xirc2ps_cs. This was kinda headache.
Simulated the original and new functions and they bahave the same.

Some driver cleanups:
* convert to use phy_find_first/phy_direct_connect
* convert to use netdev_mc_* helpers
* fixed missing validate_addr hook
* removed netdev_priv castings

Subject: mlx4: replace the dma_sync_single_range_for_cpu/device API

There are only two users of the dma_sync_single_range_for_cpu/device
API in mainline (mlx4 and ssb). The
dma_sync_single_range_for_cpu/device API has never been documented and
the dma_sync_single_for_cpu/device API also support a partial sync.

This converts mlx4 to use the dma_sync_single_for_cpu/device API
(preparations for the removal of the dma_sync_single_range_for_cpu/device API).

Subject: r8169: enable 64-bit DMA by default for PCI Express devices (v2)

Currently use of 64-bit DMA is disabled in r8169 unless the user passes the
use_dac module option. This is reasonable for conventional PCI devices where
broken chipsets may not handle dual-address-cycle transfers properly for
32-bit slots and so this may not be safe. However, PCI Express should not have
this problem and not using 64-bit DMA results in DMA transfers needlessly using
the IOMMU or SWIOTLB. Set the use_dac module parameter to a new default value of
-1 which results in 64-bit DMA being enabled by default for PCI Express devices
only.

Subject: mwl8k: convert to new station add/remove callbacks

This converts mwl8k to use the new station
add/remove callbacks instead of using the
old sta_notify callback.

The new callbacks can sleep, so a lot of
code can be removed now.

Subject: ixgbe: prevent speculative processing of descriptors before ready

The PowerPC architecture does not require loads to independent bytes to be
ordered without adding an explicit barrier.

In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.

The problem occurs with packet split enabled where the TCP/IP header and data
are in different descriptors. If the reads go out of order we may have data
that doesn't match the TCP/IP header. Since we use hardware checksumming this
bad data is never verified and it makes it all the way to the application.

This bug was found during stress testing and adding this barrier has been shown
to fix it.

Do a PHY reset to test if there is an active phy and set the PHY address
to B44_PHY_ADDR_NO_PHY in case of an not active phy. This is needed for
the Linksys WRTSL54GS and Asus WL-500W.

From e5f8d9ac46e0291594abaa76bf467a08367bcccf Mon Sep 17 00:00:00 2001
From: Tilman Schmidt <tilman@imap.cc>
Date: Mon, 22 Feb 2010 11:09:38 +0000
Subject: isdn: fix a few Kconfig imperfections

1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI.
2. The MISDN config option appeared between ISDN_I4L and the I4L hardware
   driver options; move it to a less irritating place.
3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so
   move it from the I4L section to the general section.
4. ISDN_HDLC is now also used by drivers outside I4L.  Move it from the
   I4L section to the general section, too.

-	  ISDN ("Integrated Services Digital Networks", called RNIS in France)

Subject: packet: convert socket list to RCU (v3)

Convert AF_PACKET to use RCU, eliminating one more reader/writer lock.

There is no need for a real sk_del_node_init_rcu(), because sk_del_node_init
is doing the equivalent thing to hlst_del_init_rcu already; but added
some comments to try and make that obvious.

Subject: netfilter: xt_recent: fix buffer overflow

e->index overflows e->stamps[] every ip_pkt_list_tot packets.

Consider the case when ip_pkt_list_tot==1; the first packet received is stored
in e->stamps[0] and e->index is initialized to 1. The next received packet
timestamp is then stored at e->stamps[1] in recent_entry_update(),
a buffer overflow because the maximum e->stamps[] index is 0.

Subject: Revert "iwlwifi: Monitor and recover the aggregation TX flow failure"

This reverts commit 1db5950f1d0b82e07371b211a48317b8972da063.

The goal of "iwlwifi: Monitor and recover the aggregation TX flow failure"
is to first detect when data transmission stalls and then to recover from
this situation with a reset of the radio or the firmware, depending on how
bad the transmission failures are.

Unfortunately we have found that this change causes excessive resets with
its current detection algorithm. It also performs its recovery action when
none is really needed, like when we are not associated.

Revert this change until the issues have been addressed.

Subject: iwlwifi: increase command buffer size

Increase the buffer size for commands with "huge"
bit set. This has been recently observed for 6050 cards where
for even with huge bit set few commands were not properly allocated
memory with the command overwriting the buffer allocated for it..
Also add a check to see if command size exceeds the
maximum allowable size.

From dcea992aca82cb08b4674c4c783e325835408d1e Mon Sep 17 00:00:00 2001

Date: Wed, 24 Feb 2010 18:34:48 +0100
Subject: netfilter: xtables: replace XT_MATCH_ITERATE macro

The macro is replaced by a list.h-like foreach loop. This makes
the code more inspectable.

Subject: netfilter: xtables: reduce arguments to translate_table

Just pass in the entire repl struct. In case of a new table (e.g.
ip6t_register_table), the repldata has been previously filled with
table->name and table->size already (in ip6t_alloc_initial_table).

Subject: can: netlink support for bus-error reporting and counters

This patch makes the bus-error reporting configurable and allows to
retrieve the CAN TX and RX bus error counters via netlink interface.
I have added support for the SJA1000. The TX and RX bus error counters
are also copied to the data fields 6..7 of error messages when state
changes are reported.

Subject: isa-skelton: Remove a wrong netif_wake_queue() call

The netif_wake_queue() is called correctly (i.e. only on !txfull
condition) from net_tx().  So Unconditional call to the
netif_wake_queue() here is wrong.  This might cause calling of
start_xmit routine on txfull state and trigger tx-ring overflow.

This fix is ported from commit 662a96bd6f020782dfbdc0d0bd177c7dbb556687
("tc35815: Remove a wrong netif_wake_queue() call which triggers BUG_ON").

 IOMMU enabled kernels

Work around 82599 HW issue when HWRSC is enabled on IOMMU enabled
kernels. 82599 HW is updating the header information after setting the
descriptor to done, resulting DMA mapping/unmapping issues on IOMMU
enabled systems. To work around the issue delay unmapping of first packet
that carries the header information until end of packet is reached.

when TSO is disabled netif_tx_stop_all_queues is called.  If the watchdog
timer fires while the queues are stopped and traffic has not recently been
sent on a paticular queue this is falsly identified as a hang and
ndo_tx_timeout() is called.  This is ocossionally seen during testing.

This removes the netif_tx_stop_all_queues() it is not needed.  The scheduler
submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and
if so it calls dev_gso_segment.  Disabling TSO will cause dev_hard_start_xmit()
to do the gso processing.   However ixgbe does not use the features flags to
determine if it needs to use tso or not instead it uses skb->gso_size so
ixgbe will process these frames correctly regardless of the netdev features
flag.

Subject: ixgbe: Do not allocate too many netdev txqueues

Instead of allocating 128 struct netdev_queue per device, use the
minimum value between 128 and the number of possible txq's, to
reduce ram usage and "tc -s -d class shod dev .." output.

This patch fixes Eric Dumazet's patch to set the TX queues to
the correct minimum.

Some data structures are freed when the device is down and it will

to prevent this.  In the shutdown path, ulp_ops[CNIC_ULP_L4] is
assigned NULL and rcu_synchronized before freeing the data

RFC 4291 section 2.4 states that all uncategorized addresses
should be considered as Global Unicast.

This will remove IPV6_ADDR_RESERVED completely
and return IPV6_ADDR_UNICAST in ipv6_addr_type() instead.

Subject: ipv6: Use 1280 as min MTU for ipv6 forwarding

Clients will set their MTU to 1280 if they receive a
ICMPV6_PKT_TOOBIG message with an MTU less than 1280.

To allow encapsulating of packets over a 1280 link
we should always accept packets with a size of 1280
for forwarding even if the path has a lower MTU and
fragment the encapsulated packets afterwards.

In case a forwarded packet is not going to be encapsulated
a ICMPV6_PKT_TOOBIG msg will still be send by ip6_fragment()
with the correct MTU.

Subject: Revert "ethtool: Add n-tuple string length to drvinfo and return it"

This reverts commit c79c5ffdce14abb4de3878c5aa8c3c6e5093c69b.

As Jeff points out we can't break the user visible interface
like this, we need to add this into the reserved[] thing.

Subject: netfilter: nfnetlink_log: fix silly refcount leak

Quick fix for memory/module refcount leak.
Reference count of listener instance never reaches 0.

Start/stop of ulogd2 is enough to trigger this bug!

Now, refcounting there looks very fishy in particular this code:

 	if (!try_module_get(THIS_MODULE)) {
		...

and creation of listener instance with refcount 2,
so it may very well be ripped and redone.  :-)

Subject: net: Delete isa-skeleton net driver

The ISA skeleton net driver has been obsolete and unmaintained for many
years.  Any hardware remotely like ISA will use the platform API and
look much more like a PCI driver, and make much better use of netdev
APIs such as NAPI.

Subject: ath9k: disable RIFS search for AR91xx based chips

While ath9k does not support RIFS yet, the ability to receive RIFS
frames is currently enabled for most chipsets in the initvals.
This is causing baseband related issues on AR9160 and AR9130 based
chipsets, which can lock up under certain conditions.

This patch fixes these issues by overriding the initvals, effectively
disabling RIFS for all affected chipsets.

Subject: mac80211: use listen interval 5 as default

Currently if a driver does not set hw.max_listen_interval a listen
interval of 1 is negotiated with the AP. Thus, the AP could drop
buffered frames for us after just one beacon interval which can
easily happen with the current powersave and scan implementation.
To avoid this issue increase the default interval to 5 which should
be a reasonable safe default.

effectively reverted "net: Set LL_MAX_HEADER properly for wireless." by

If authentication has already been performed when the WLAN interface is
stopped, (sometimes) the ieee80211_work_purge would corrupt some
ieee80211_work-structures. The outcome is this (cleaned up):

Subject: b43: fall back gracefully to PIO mode after fatal DMA errors

This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.

The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

(Some post-2.6.33 merge fixups by Larry Finger <Larry.Finger@lwfinger.net>
and yours truly... -- JWL)

MPC5121 FEC requeries 4-byte alignmnent for TX data buffers.
This patch is a work around that copies misaligned tx packets
to an aligned skb before sending.

Subject: rtnetlink: ignore NETDEV_PRE_UP notifier in rtnetlink_event()

Commit 3b8bcfd (net: introduce pre-up netdev notifier) added a new
notifier which is run before a device is set UP for use by cfg80211.

The patch missed to add the new notifier to the ignore list in
rtnetlink_event(), so we currently get an unnecessary netlink
notification before a device is set UP.

Subject: rtnetlink: handle rtnl_link netlink notifications manually

In order to support specifying device flags during device creation,
we must be able to roll back device registration in case setting the
flags fails without sending any notifications related to the device
to userspace.

This patch changes rollback_registered_many() and register_netdevice()
to manually send netlink notifications for devices not handled by
rtnl_link and allows to defer notifications for devices handled by
rtnl_link until setup is complete.

Subject: dev: support deferring device flag change notifications

Split dev_change_flags() into two functions: __dev_change_flags() to
perform the actual changes and __dev_notify_flags() to invoke netdevice
notifiers. This will be used by rtnl_link to defer netlink notifications
until the device has been fully configured.

This changes ordering of some operations, in particular:

- netlink notifications are sent after all changes have been performed.
  As a side effect this surpresses one unnecessary netlink message when
  the IFF_UP and other flags are changed simultaneously.

- The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked
  after all changes have been performed. Their relative is unchanged.

- net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead
  of afterwards. This should not make any difference since both RX and TX
  are already shut down at this point.

From 3729d5021257b283f7fce33d957893162ccb2c9d Mon Sep 17 00:00:00 2001
From: Patrick McHardy <kaber@trash.net>

Subject: rtnetlink: support specifying device flags on device creation

commit e8469ed959c373c2ff9e6f488aa5a14971aebe1f
Author: Patrick McHardy <kaber@trash.net>
Date:   Tue Feb 23 20:41:30 2010 +0100

Support specifying the initial device flags when creating a device though
rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING
in order to surpress netlink registration notifications. To complete setup,
rtnl_configure_link() must be called, which performs the device flag changes
and invokes the deferred notifiers if everything went well.

Two examples:

# add macvlan to eth0
#
$ ip link add link eth0 up allmulticast on type macvlan

[LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN

Subject: skbuff: align sk_buff::cb to 64 bit and close some potential holes

The alignment requirement for 64-bit load/store instructions on ARM is
implementation defined. Some CPUs (such as Marvell Feroceon) do not
generate an exception, if such an instruction is executed with an
address that is not 64 bit aligned. In such a case, the Feroceon
corrupts adjacent memory, which showed up in my tests as a crash in the
rx path of ath9k that only occured with CONFIG_XFRM set.

This crash happened, because the first field of the mac80211 rx status
info in the cb is an u64, and changing it corrupted the skb->sp field.

This patch also closes some potential pre-existing holes in the sk_buff
struct surrounding the cb[] area.

Subject: ixgbe: move TC_PRIO_CONTROL check into ixgbe_select_queue()

Move TC_PRIO_CONTROL check and queue remapping into
ixgbe_select_queue().  Remapping queues after the qdisc
can result in the wrong qdisc queue being stopped with
netif_stop_subqueue().  Even if this is resolved and the
correct queue is stopped it can result in a queue being
blocked by TC_PRIO_CONTROL frames uneccesarily.  Moving
this into the select_queue routine maintains alignment
between tx_rings and qdisc queues.

Subject: Bluetooth: Convert controller hdev->type to hdev->bus

The hdev->type is misnamed and should be actually hdev->bus instead. So
convert it now.

Subject: Bluetooth: Convert Marvell driver to use per adapter debugfs

The debugfs support of the Marvell driver is buggy. It is limited to one
controller per system. Fix this by using the controller specific debugfs
directory as parent.

Subject: Bluetooth: Add controller types for BR/EDR and 802.11 AMP

With the Bluetooth 3.0 specification and the introduction of alternate
MAC/PHY (AMP) support, it is required to differentiate between primary
BR/EDR controllers and 802.11 AMP controllers. So introduce a special
type inside HCI device for differentiation.

For now all AMP controllers will be treated as raw devices until an
AMP manager has been implemented.

Subject: Bluetooth: Add SCO fallback for unsupported feature error

The Bluetooth SIG PTS test case: TC_AG_ACS_BV_10_I, rejects eSCO with
"Unsupported Feature or Parameter Value" (0x11).  This patch adds case
for SCO fallback.

Subject: pci: Add large and small resource data type code

This patch introduces more VPD preprocessor definitions to identify some
small and large resource data type item names.  The patch then continues
to correct how the tg3 and bnx2 drivers search for the "read-only data"
large resource data type.

Subject: Bluetooth: Fix out of scope variable access in hci_sock_cmsg()

The pointer data can point to the variable ctv.
Access to data happens when ctv is already out of scope.

Subject: bridge: Do br_pass_frame_up after other ports

At the moment we deliver to the local bridge port via the function
br_pass_frame_up before all other ports.  There is no requirement
for this.

For the purpose of IGMP snooping, it would be more convenient if
we did the local port last.  Therefore this patch rearranges the
bridge input processing so that the local bridge port gets to see
the packet last (if at all).

Subject: bridge: Avoid unnecessary clone on forward path

When the packet is delivered to the local bridge device we may
end up cloning it unnecessarily if no bridge port can receive
the packet in br_flood.

This patch avoids this by moving the skb_clone into br_flood.

This patch moves the main loop body in br_flood into the function
may_deliver.  The code that clones an skb and delivers it is moved
into the deliver_clone function.

This allows this to be reused by the future multicast forward
function.

Subject: bridge: Add core IGMP snooping support

This patch adds the core functionality of IGMP snooping support
without actually hooking it up.  So this patch should be a no-op
as far as the bridge's external behaviour is concerned.

All the new code and data is controlled by the Kconfig option
BRIDGE_IGMP_SNOOPING.  A run-time toggle is also available.

The multicast switching is done using an hash table that is
lockless on the read-side through RCU.  On the write-side the
new multicast_lock is used for all operations.  The hash table
supports dynamic growth/rehashing.

The hash table will be rehashed if any chain length exceeds a
preset limit.  If rehashing does not reduce the maximum chain
length then snooping will be disabled.

These features may be added in future (in no particular order):

* IGMPv3 source support
* Non-querier router detection
* IPv6

Subject: bridge: Add multicast forwarding functions

This patch adds code to perform selective multicast forwarding.

We forward multicast traffic to a set of ports plus all multicast
router ports.  In order to avoid duplications among these two
sets of ports, we order all ports by the numeric value of their
pointers.  The two lists are then walked in lock-step to eliminate
duplicates.

Subject: bridge: Add multicast data-path hooks

This patch finally hooks up the multicast snooping module to the
data path.  In particular, all multicast packets passing through
the bridge are fed into the module and switched by it.

Subject: bridge: Add multicast_router sysfs entries

This patch allows the user to forcibly enable/disable ports as
having multicast routers attached.  A port with a multicast router
will receive all multicast traffic.

The value 0 disables it completely.  The default is 1 which lets
the system automatically detect the presence of routers (currently
this is limited to picking up queries), and 2 means that the port
will always receive all multicast traffic.

This patch allows the user to disable IGMP snooping completely
through a sysfs toggle.  It also allows the user to reenable
snooping when it has been automatically disabled due to hash
collisions.  If the collisions have not been resolved however
the system will refuse to reenable snooping.

Subject: bridge: Add hash elasticity/max sysfs entries

This patch allows the user to control the hash elasticity/max
parameters.  The elasticity setting does not take effect until
the next new multicast group is added.  At which point it is
checked and if after rehashing it still can't be satisfied then
snooping will be disabled.

The max setting on the other hand takes effect immediately.  It
must be a power of two and cannot be set to a value less than the
current number of multicast group entries.  This is the only way
to shrink the multicast hash.

Subject: netlink: Adding inode field to /proc/net/netlink

The Inode field in /proc/net/{tcp,udp,packet,raw,...} is useful to know the types of
file descriptors associated to a process. Actually lsof utility uses the field.
Unfortunately, unlike /proc/net/{tcp,udp,packet,raw,...}, /proc/net/netlink doesn't have the field.
This patch adds the field to /proc/net/netlink.

Apparently bogus mc address can break IPOIB multicast processing. Therefore
returning the check for addrlen back until this is resolved in bonding (I don't
see any other point from where mc address with non-dev->addr_len length can came
from).

Subject: ethtool: do not set some flags, if others failed

NETIF_F_NTUPLE flag setting introduced a bug:  non-ntuple flags
like LRO may be successfully set, before ioctl(2) returns failure
to userspace.

The set-flags operation should be all-or-none, rather than leaving
things in an inconsistent state prior to reporting failure to
userspace.

vhost was dong some complex math to get
offset to log at, and got it wrong by a couple of bytes,
while in fact it's simple: get address where we write,
subtract start of buffer, add log base.

Do it this way.

guest to remote communication with vhost net sometimes stops until

Subject: bnx2x: Tx barriers and locks

[Resending with the proper subject. Sorry for the mess. ]

This patch is based on the RFC of Stanislaw Gruszka.

More specifically it fixes two possible races:
- One, described by Stanislaw, may lead to permanent disabling of the Tx
queue.
This is fixed by adding the smp_wmb() to propagate the BD consumer
change towards the memory.
- Second may lead to bnx2x_start_xmit() returning NETDEV_TX_BUSY.
This is fixed by taking a tx_lock() before rechecking the number of
available Tx BDs.

thanks,
vlad

Subject: be2net: fix tx completion polling

In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
but before re-enabling interrupts (via a cq notify).
