      mac80211: Fix a race on enabling power save. · f3e85b9e
      Vivek Natarajan authored
      There is a race on sending a data frame before the tx completion
      of nullfunc frame for enabling power save. As the data quickly
      follows the nullfunc frame, the AP thinks that the station is out
      of power save and continues to send the frames. Whereas in the
      station, the nullfunc ack will be processed after the tx completion
      of data frame and mac80211 goes to powersave. Thus the power
      save state mismatch between the station and the AP causes some
      data loss and some applications fail because of that. This patch
      fixes this issue.

      mac80211: fix conn_mon_timer running after disassociate · 05e7c991
      Stanislaw Gruszka authored
      Low level driver could pass rx frames to us after disassociate, what
      can lead to run conn_mon_timer by ieee80211_sta_rx_notify(). That
      is obviously wrong, but nothing happens until we unload modules and
      resources are used after free. If kernel debugging is enabled following
      warning could be observed:

      cfg80211: Extend channel to frequency mapping for 802.11j · 59eb21a6
      Bruno Randolf authored
      Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to
      IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping
      channel numbers in the 2GHz and 5GHz band we can't map from channel to
      frequency without knowing the band. This is no problem as in most contexts we
      know the band. In places where we don't know the band (and WEXT compatibility)
      we assume the 2GHz band for channels below 14.
      
      This patch does not implement all channel to frequency mappings defined in
      802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz
      channels as well as 802.11y channels have been omitted.
      
      The following drivers have been updated to reflect the API changes:
      iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx.
      The drivers have been compile-tested only.

      mac80211: Fix WMM driver queue configuration · f2176d72
      Juuso Oikarinen authored
      The WMM parameter configuration function (ieee80211_sta_wmm_params) only
      configures the WMM parameters to the driver is the wmm_last_param_set
      counter value is changed by the AP.
      
      The wmm_last_param_set is initialized to -1 on association in order to ensure
      the configuration is made to the driver at least once on association, but
      currently this initialization is done *after* the WMM parameter configuration
      function was called.
      
      This leads to unreliability in the driver getting properly configured on first
      association (depending on what counter value the AP happens to use.) When
      disassociating (the wmm default parameters are configured to the driver) and
      then reassociating, due to the above the WMM configuration is not set to the
      driver at all.
      
      On drivers without beacon filtering the problem is corrected by later beacons,
      but on drivers with beacon filtering the WMM will remain permanently incorrectly
      configured.
      
      Fix this by moving the initialization of wmm_last_param_set to -1 before
      ieee80211_sta_wmm_params is called on association.
