      ath9k: Revert change that broke AR928X on Acer Ferrari One · a7322812
      由 Rafael J. Wysocki 提交于 
      Revert a hunk in drivers/net/wireless/ath/ath9k/hw.c introduced by
commit 2577c6e8 (ath9k_hw: Add
support for AR946/8x chipsets) that caused a nasty regression to
appear on my Acer Ferrari One (the box locks up entirely at random
times after the wireless has been started without any way to get
debug information out of it).

      rtlwifi: fix lps_lock deadlock · e55b32c1
      由 Stanislaw Gruszka 提交于 
      rtl_lps_leave can be called from interrupt context, so we have to
disable interrupts when taking lps_lock.

Below is full lockdep info about deadlock:

      mac80211: don't stop a single aggregation session twice · 24f50a9d
      由 Johannes Berg 提交于 
      Nikolay noticed (by code review) that mac80211 can
attempt to stop an aggregation session while it is
already being stopped. So to fix it, check whether
stop is already being done and bail out if so.

Also move setting the STOPPING state into the lock
so things are properly atomic.

      mwifiex: fix association issue with AP configured in hidden SSID mode · fada1058
      由 Amitkumar Karwar 提交于 
      Firmware expects 'max_ssid_length' field in
'struct mwifiex_ie_types_wildcard_ssid_params' to be '0' for
performing SSID specific scan. Currently driver updates it with
an actual SSID length. Hence UUT is not able to find the AP
configured in hidden SSID mode in scan results and association
fails.

max_ssid_length is filled with '0' to fix the issue.

      iwlwifi: avoid a panic when unloading the module with RF Kill · 43e58856
      由 Emmanuel Grumbach 提交于 
      When HW RF kill switch is set to kill the radio, our NIC issues an
interrupt after we stop the APM module. When we unload the module,
the driver disables and cleans the interrupts before stopping the
APM. So we have a real interrupt (inta not zero) pending.
When this interrupts pops up the tasklet has already been killed
and we crash.

Here is a logical description of the flow:

disable and clean interrupts
synchronize interrupts
kill the tasklet

stop the APM <<== creates an RF kill interrupt

free_irq <<== somehow our ISR is called here and we crash

Here is the panic message:

      mac80211: fix race between connection monitor & suspend · 0ecfe806
      由 Johannes Berg 提交于 
      When the connection monitor timer fires right before
suspend, the following will happen:
 timer fires -> monitor_work gets queued
 suspend calls ieee80211_sta_quiesce
 ieee80211_sta_quiesce:
  - deletes timer
  - cancels monitor_work synchronously, running it
  [note wrong order of these steps]
 monitor_work runs, re-arming the timer
 later, timer fires while system should be quiesced

This causes a warning:

WARNING: at net/mac80211/util.c:540 ieee80211_can_queue_work+0x35/0x40 [mac80211]()

but is otherwise harmless. I'm not completely sure
this is the scenario Thomas stumbled across, but it
is the only way I can right now see the warning in
a scenario like the one he reported.

      cfg80211: fix bug on regulatory core exit on access to last_request · 58ebacc6
      由 Luis R. Rodriguez 提交于 
      Commit 4d9d88d1 by Scott James Remnant <keybuk@google.com> added
the .uevent() callback for the regulatory device used during
the platform device registration. The change was done to account
for queuing up udev change requests through udevadm triggers.
The change also meant that upon regulatory core exit we will now
send a uevent() but the uevent() callback, reg_device_uevent(),
also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.

This fix is required for kernels >= v2.6.39

$ git describe --contains 4d9d88d1
v2.6.39-rc1~468^2~25^2^2~21

The impact of not having this present is that a bogus paging
access may occur (only read) upon cfg80211 unload time. You
may also get this BUG complaint below. Although Johannes
could not reproduce the issue this fix is theoretically correct.

      由 Johannes Berg 提交于 
      ieee80211_probereq_get() can return NULL in
which case we should clean up & return NULL
in ieee80211_build_probe_req() as well.

      mac80211: fix NULL dereference in radiotap code · f8d1ccf1
      由 Johannes Berg 提交于 
      When receiving failed PLCP frames is enabled, there
won't be a rate pointer when we add the radiotap
header and thus the kernel will crash. Fix this by
not assuming the rate pointer is always valid. It's
still always valid for frames that have good PLCP
though, and that is checked & enforced.

This was broken by my
commit fc885189
Author: Johannes Berg <johannes.berg@intel.com>
Date:   Fri Jul 30 13:23:12 2010 +0200

    mac80211: don't check rates on PLCP error frames

where I removed the check in this case but didn't
take into account that the rate info would be used.

      ath: Fix NULL ptr dereference in ath_reg_apply_world_flags · a59be081
      由 Helmut Schaa 提交于 
      This happens with devices using a regulatory domain 0x68 that are only
5Ghz capable because ath_reg_apply_active_scan_flags assumes that we
always have a 2,4Ghz band.
