      mac80211: stop polling in disassociation · 79543d8e
      由 David Spinadel 提交于 
      Stop connection monitor poll during disassociation.
This clears the polling flags and if a scan was
deferred it will be run.

Without this fix, if a scan was deferred due to
connection monitoring while disassociation happens,
this scan blocks further scan requests until interface
down/up which causes problems connecting to another AP.

      cfg80211: fix potential deadlock in regulatory · fe20b39e
      由 Eliad Peller 提交于 
      reg_timeout_work() calls restore_regulatory_settings() which
takes cfg80211_mutex.

reg_set_request_processed() already holds cfg80211_mutex
before calling cancel_delayed_work_sync(reg_timeout),
so it might deadlock.

Call the async cancel_delayed_work instead, in order
to avoid the potential deadlock.

This is the relevant lockdep warning:

      mwifiex: fix incorrect privacy setting in beacon and probe response · 6ddcd464
      由 Avinash Patil 提交于 
      Test procedure:
1. Start AP with security setting (e.g. WPA2)
2. Stop AP
3. Start AP with open security

Here it's observed that privacy is enabled in beacons and
probe responses.

This patch fixes it by checking the privacy parameter from
cfg80211_ap_settings. If privacy is not set in cfg80211_ap_settings,
set open authentication and no encryption in FW.

      rndis_wlan: fix matching bssid check in rndis_check_bssid_list() · b0fd49b7
      由 Jussi Kivilinna 提交于 
      rndis_check_bssid_list() originally tried to check if bssid->mac and
match_bssid are equal using compare_ether_addr() when it should use
!compare_ether_addr(). This check was added by commit
b5257c95 as part of workaround for
hardware issue.

Commit 2e42e474 that replaced
compare_ether_addr with ether_addr_equal relieved that this compare
to be inverse of what it should be.

Compare was added as response to hardware bug, where bssid-list does
not contain BSSID and other information of currently connected AP
(spec insists that device must provide this information in the list
when connected). Lack bssid-data on current connection then causes
WARN_ON somewhere in cfg80211. Workaround was to check if bssid-list
returns current bssid and if it does not, manually construct bssid
information in other ways. And this workaround worked, with inverse
check. Which must mean that when hardware is experiencing the problem,
it's actually returning empty bssid-list and this check didn't make
any difference for workaround.

However inverse check causes workaround be activated when bssid-list
returns only entry, currently connected BSSID. That does not cause
problems in itself, just slightly more inaccurate information in
scan-list.

      ath9k: Fix a WARNING on suspend/resume with IBSS · 2031b4c2
      由 Mohammed Shafi Shajakhan 提交于 
      this patch is dependent on the patch "cfg80211: fix interface
combinations"

In ath9k currently we have ADHOC interface as a single incompatible
interface. when drv_add_interface is called during resume we got to
consider number of vifs already present in addition to checking the
drivers 'opmode' information about ADHOC.  we incorrectly assume
an ADHOC interface is already present. Then we may miss some driver
specific data for the ADHOC interface after resume.

The above mentioned checks can be removed from the driver,
as the patch 'cfg80211: fix interface combinations' ensures that
if an interface type is not advertised by the driver in any of the
interface combinations(via ieee80211_iface_combination) then it shall
be treated as a single incompatible interface. Fixes the following
warning on suspend/resume with ibss interface.

        ath: phy0: Cannot create ADHOC interface when other
        interfaces already exist.
