ath6kl: Fix the byte alignment rule to avoid loss of bytes in a TCP segment
Either first 3 bytes of the first received tcp segment or last one
over MTU size file can be loss due to the byte alignment problem.
Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header
alignment' in the patch "Fix buffer alignment for scatter-gather
I/O"(1df94a857), there exists the bytes loss issue which means that it will be
truncated 3 bytes in the transmitted file contents if a file which has over MTU
size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack
bug of 3.5 or the latest version of kernel but the byte alignment issue. This
patch is to use the roundup() function for the byte alignment rather than the
predefined ATH6KL_HTC_ALIGN_BYTES.

ath6kl: restart concurrent vifs on failed connect
When an ath6kl STA vif is issued a connect command, the firmware will
disconnect all other beaconing vifs in preparation for a potential
channel switch. The case where the connect fails is currently unhandled,
so if a connection attempt on a STA vif fails and any vifs were waiting
for a new channel, simply restart the concurrent vifs on their previous
channel.
Requires that we start tracking the last issued channel in ar->last_ch,
which is valid since ath6kl only supports 1 channel at a time.
Also clear the beaconing vif's want_ch_switch bit regardless of whether
channel switch succeeds, to stop recommitting the same failed profile.

ath6kl: Maintain the listen interval per VIF specific
Firmware has the option to support the listen interval
per vif specific. Fix this.
Listen interval can be set by the TUs or by the number
of beacons. Current code enables the user to configure
the listen interval in the unit of 'number of beacons'
using debugfs entry "listen_interval". Going forward,
we need to alter the listen interval in the unit of TUs
to get good power numbers while going to WOW suspend/resume.
Allowing the user to change the listen interval in
the unit of "number of beacons" in debugfs and changing
listen interval in wow suspend/resume in the unit of
time (TUs) would lead us to confuse.
This patch make sures the listen interval is changed only
in the unit of time (TUs).

* When a station has APSD capability and goes to power save, the frame
designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
host delivers the buffered frame from the APSD power save queue.
Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
queue are dropped.
* When the host queues the first frame to the APSD queue or removes the

ath6kl: Fix listen interval handling
This patch addresses a few problems with the commit:
"ath6kl: Implement support for listen interval from userspace"
* The debugfs file required for reading/writing the listen interval
wasn't created. Fix this.
* The interface index was being hardcoded to zero. Fix this.
* Two separate parameters, "listen_interval_time and listen_interval_beacons"
were being used. This fails to work as expected because the FW assigns
higher precedence to "listen_interval_beacons" and "listen_interval_time"
ends up being never used at all.
To handle this, fix the host driver to exclusively use listen interval
based on units of beacon intervals.
To set the listen interval, a user would now do something like this:
echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval
kvalo: fix two checkpatch warnings

There are still some issues with the checksum offload so better to

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

ath6kl: don't power down hardware when interface is down
Jouni reported that my patch "ath6kl: power down hardware when interface
is down" caused a regression on his x86 boxes and scan didn't work anymore.
I was able to reproduce the problem by disabling all debug messages.
So there has to be a race condition somewhere in the code and disable the
functionality until the race is fixed. Now hardware is powered from the
point where module is loaded until it's removed.

are being used.
(&(&ar->lock)->rlock){+.-...}, at: [<ffffffffa0492d13>] ath6kl_indicate_tx_activity+0x83/0x110 [ath6kl]
but this lock took another, SOFTIRQ-unsafe lock in the past:
(&(&ar->list_lock)->rlock){+.+...}
and interrupts could create inverse lock ordering between them.
other info that might help us debug this:
Possible interrupt unsafe locking scenario:
CPU0 CPU1
---- ----
lock(&(&ar->list_lock)->rlock);
local_irq_disable();
lock(&(&ar->lock)->rlock);
lock(&(&ar->list_lock)->rlock);
<Interrupt>
lock(&(&ar->lock)->rlock);
*** DEADLOCK ***
softirqs have to be disabled when acquiring ar->list_lock to avoid
the above deadlock condition. When the above warning printed the
interface is still up and running without issue.

ath6kl: add aborted parameter to ath6kl_cfg80211_scan_complete_event()
Currently it takes an error code as status, but what we really want to
tell is if the scan was aborted or not.
Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success
status code and checking for that.

ath6kl: power down hardware when interface is down
The benefit from this is that user space can control hardware's power state
by putting interface up and down. This is handy if firmware gets to some
weird state.
The downside will be that putting interface up takes a bit longer,
I was measuring ~500 ms during interface up.

ath6kl: make sure WLAN power save is enabled during suspend
Power save is enabled during ath6kl init. But when user space disables power
save, the system will go into suspend with power save disabled. The ath6kl
driver will now explicitly enable power save prior to entering suspend and
restore its previous setting upon resume

ath6kl: Update BSS information after connection
Since we may end up using a dummy BSS entry when roaming, allow one Beacon
frame -based bssinfo from the current BSS to be processed prior to starting
to filter all bssinfo events. This allows cfg80211 BSS table to be filled
with proper data in the roaming case where the full Beacon data may not
have been present at the time of roamed event.

Configuration of the WEP keys needs to be delayed until the AP mode has

ath6kl: Fix AP mode connect event parsing and TIM updates
This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.
The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.

Just to make them a bit easier to read and unify naming. 32 suffix

Use void pointers to get rid of ugly casts.
Don't provide target address as a pointer, pass it by value. Same for

Add ath6kl cleaned up driver
Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:
http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary
After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.
The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)
There are two remaining checkpatch warnings in the driver which we
decided to omit for now:
drivers/net/wireless/ath/ath6kl/debug.c:31:
WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.txt
The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.
We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.
Notable missing features compared to the current staging driver are:
o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support
Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.
Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.
Various people have been working on the cleanup, the hall of
fame based on number of patches is:
