      My
        commit 77fdaa12
        Author: Johannes Berg <johannes@sipsolutions.net>
        Date:   Tue Jul 7 03:45:17 2009 +0200
      
            mac80211: rework MLME for multiple authentications
      
      inadvertedly broke WMM because it removed, along with
      a bunch of other now useless initialisations, the line
      initialising sdata->u.mgd.wmm_last_param_set to -1
      which would make it adopt any WMM parameter set. If,
      as is usually the case, the AP uses WMM parameter set
      sequence number zero, we'd never update it until the
      AP changes the sequence number.
      
      Add the missing initialisation back to get the WMM
      settings from the AP applied locally.

      mac80211: fix peer HT capabilities · 9a418af5
      Johannes Berg 提交于
      I noticed yesterday, because Jeff had noticed
      a speed regression, cf. bug
      http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138
      that the SM PS settings for peers were wrong.
      Instead of overwriting the SM PS settings with
      the local bits, we need to keep the remote bits.
      
      The bug was part of the original HT code from
      over two years ago, but unfortunately nobody
      noticed that it makes no sense -- we shouldn't
      be overwriting the peer's setting with our own
      but rather keep it intact when masking the peer
      capabilities with our own.
      
      While fixing that, I noticed that the masking of
      capabilities is completely useless for most of
      the bits, so also fix those other bits.
      
      Finally, I also noticed that PSMP_SUPPORT no
      longer exists in the final 802.11n version, so
      also remove that.

      Libertas: fix buffer overflow in lbs_get_essid() · 45b24168
      Daniel Mack 提交于
      The libertas driver copies the SSID buffer back to the wireless core and
      appends a trailing NULL character for termination. This is
      
      a) unnecessary because the buffer is allocated with kzalloc and is hence
         already NULLed when this function is called, and
      
      b) for priv->curbssparams.ssid_len == 32, it writes back one byte too
         much which causes memory corruptions.
      
      Fix this by removing the extra write.

      The MIB counters are disabled when doing a chip reset.
      Since ANI depends on the MIB registers for its operation, relying
      on the contents of said registers during HW reset results in sub-optimal

      iwlwifi: initialize spinlock before use · 731a29b7
      Reinette Chatre 提交于
      Recent powersaving work resulted in power management ops being called
      during EEPROM initialization. The lock used by these functions is not
      initialized at this time. Ensure lock is initialized before it is used.

      iwl3945: disable power save · bc45a670
      Reinette Chatre 提交于
      we see from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2125
      that power saving does not work well on 3945. Since then power saving has
      also been connected with association problems where an AP deathenticates a
      3945 after it is unable to transmit data to it - this happens when 3945
      enters power savings mode.
      
      Disable power save support until issues are resolved.
