      mwifiex: fix association issue with AP configured in hidden SSID mode · fada1058
      Amitkumar Karwar authored
      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
      max_ssid_length is filled with '0' to fix the issue.

      iwlwifi: avoid a panic when unloading the module with RF Kill · 43e58856
      Emmanuel Grumbach authored
      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
      Johannes Berg authored
      When the connection monitor timer fires right before
      suspend, the following will happen:
       timer fires -> monitor_work gets queued
       suspend calls 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
      Luis R. Rodriguez authored
      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
      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.

      mac80211: fix NULL dereference in radiotap code · f8d1ccf1
      Johannes Berg authored
      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
