      mac80211: pid, fix memory corruption · 6909268d
      Jiri Slaby authored
      
      
      pid doesn't count with some band having more bitrates than the one
      associated the first time.
      Fix that by counting the maximal available bitrate count and allocate
      big enough space.
      
      Secondly, fix touching uninitialized memory which causes panics.
      Index sucked from this random memory points to the hell.
      The fix is to sort the rates on each band change.

      Jiri Slaby authored
      
      
      minstrel doesn't count max rate count in fact, since it doesn't use
      a loop variable `i' and hence allocs space only for bitrates found in
      the first band.
      
      Fix it by involving the `i' as an index so that it traverses all the
      bands now and finds the real max bitrate count.

      cfg80211: fix bug while trying to process beacon hints on init · b1ed8ddd
      Luis R. Rodriguez authored
      During initialization we would not have received any beacons
      so skip processing reg beacon hints, also adds a check to
      reg_is_world_roaming() for last_request before accessing its
      fields.
      
      This should fix this:

      cfg80211: fix race condition with wiphy_apply_custom_regulatory() · ac46d48e
      Luis R. Rodriguez authored
      
      
      We forgot to lock using the cfg80211_mutex in
      wiphy_apply_custom_regulatory(). Without the lock
      there is possible race between processing a reply from CRDA
      and a driver calling wiphy_apply_custom_regulatory(). During
      the processing of the reply from CRDA we free last_request and
      wiphy_apply_custom_regulatory() eventually accesses an
      element from last_request in the through freq_reg_info_regd().
      
      This is very difficult to reproduce (I haven't), it takes us
      3 hours and you need to be banging hard, but the race is obvious
      by looking at the code.
      
      This should only affect those who use this caller, which currently
      is ath5k, ath9k, and ar9170.

      iwlwifi: update key flags at time key is set · 299f5462
      Reinette Chatre authored
      We need to be symmetrical in what is done when key is set and cleared.
      This is important wrt the key flags as they are used during key
      clearing and if they are not set when the key is set the key cannot be
      cleared completely.
      
      This addresses the many occurences of the WARN found in
      iwl_set_tkip_dynamic_key_info() and tracked in
      http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key
      
      
      
      If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key()
      pair a few times in a row will cause that we run out of key space.
      This is because the index stored in the key flags is used by
      iwl_remove_dynamic_key() to decide if it should remove the key.
      Unfortunately the key flags, and hence the key index is currently only
      set at the time the key is written to the device (in
      iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info().
      Fix this by setting flags in iwl_set_tkip_dynamic_key_info().

      mac80211: correct fragmentation threshold check · 8ccd8f21
      Johannes Berg authored
      The fragmentation threshold is defined to be including the

      mv643xx_eth: 64bit mib counter read fix · 93af7aca
      Lennert Buytenhek authored
      
      
      On several mv643xx_eth hardware versions, the two 64bit mib counters
      for 'good octets received' and 'good octets sent' are actually 32bit
      counters, and reading from the upper half of the register has the same
      effect as reading from the lower half of the register: an atomic
      read-and-clear of the entire 32bit counter value.  This can under heavy
      traffic occasionally lead to small numbers being added to the upper
      half of the 64bit mib counter even though no 32bit wrap has occured.
      
      Since we poll the mib counters at least every 30 seconds anyway, we
      might as well just skip the reads of the upper halves of the hardware
      counters without breaking the stats, which this patch does.

      mv643xx_eth: OOM handling fixes · 1319ebad
      Lennert Buytenhek authored
      
      
      Currently, when OOM occurs during rx ring refill, mv643xx_eth will get
      into an infinite loop, due to the refill function setting the OOM bit
      but not clearing the 'rx refill needed' bit for this queue, while the
      calling function (the NAPI poll handler) will call the refill function
      in a loop until the 'rx refill needed' bit goes off, without checking
      the OOM bit.
      
      This patch fixes this by checking the OOM bit in the NAPI poll handler
      before attempting to do rx refill.  This means that once OOM occurs,
      we won't try to do any memory allocations again until the next invocation
      of the poll handler.
      
      While we're at it, change the OOM flag to be a single bit instead of
      one bit per receive queue since OOM is a system state rather than a
      per-queue state, and cancel the OOM timer on entry to the NAPI poll
      handler if it's running to prevent it from firing when we've already
      come out of OOM.

      In "mac80211: correct wext transmit power handler"

      is always set to 0, causing associations to time out and similar
      problems since we're transmitting with very little power. Correct
      this by correcting the default user_power_level to -1.

      - ieee80211_wep_init(), which is called with rtnl_lock held, blocks in

       - modprobe blocks in a call to flush_workqueue(), when it closes a TTY
         [presumably when it exits].
      
       - The workqueue item linkwatch_event() blocks on rtnl_lock.
      
      There's no reason for wep_init() to be called with rtnl_lock held, so
      just move it outside the critical section.

      e100: do not go D3 in shutdown unless system is powering off · ac7c992c
      Thadeu Lima de Souza Cascardo authored
      
      
      After experimenting with kexec with the last merges after 2.6.29, I've
      had some problems when probing e100.  It would not read the eeprom.  After
      some bisects, I realized this has been like that since forever (at least
      2.6.18).  The problem is that shutdown is doing the same thing that
      suspend does and puts the device in D3 state.  I couldn't find a way to
      get the device back to a sane state in the probe function.  So, based on
      some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe,
      I wrote this one for e100.

      netfilter: revised locking for x_tables · 942e4a2b
      Stephen Hemminger authored
      
      
      The x_tables are organized with a table structure and a per-cpu copies
      of the counters and rules. On older kernels there was a reader/writer 
      lock per table which was a performance bottleneck. In 2.6.30-rc, this
      was converted to use RCU and the counters/rules which solved the performance
      problems for do_table but made replacing rules much slower because of
      the necessary RCU grace period.
      
      This version uses a per-cpu set of spinlocks and counters to allow to
      table processing to proceed without the cache thrashing of a global

      ath5k: fix buffer overrun in rate debug code · b7fcb5c4
      Bob Copeland authored
      
      
      char bname[5] is too small for the string "X GHz" when the null
      terminator is taken into account.  Thus, turning on rate debugging
      can crash unless we have lucky stack alignment.

      iwlwifi: notify on scan completion even when shutting down · 74aa9be0
      Johannes Berg authored
      
      
      Under certain circumstances iwlwifi can get stuck and will no
      longer accept scan requests, because the core code (cfg80211)
      thinks that it's still processing one. This fixes one of the
      points where it can happen, but I've still seen it (although
      only with my radio-off-when-idle patch).

      rndis_wlan: fix initialization order for workqueue&workers · e805e4d0
      Jussi Kivilinna authored
      rndis_wext_link_change() might be called from rndis_command() at
      initialization stage and priv->workqueue/priv->work have not been
      initialized yet. This causes invalid opcode at rndis_wext_bind on
      some brands of bcm4320.
      
      Fix by initializing workqueue/workers in rndis_wext_bind() before
      rndis_command is used.

      wireless: remove unneeded EXPORT_SYMBOL the tickles a powerpc compiler bug · 6269b731
      Stephen Rothwell authored
      
      
      drivers/net/wireless/iwlwifi/iwl3945-base.c:1415: error: __ksymtab_iwl3945_rx_queue_reset causes a section type conflict
      
      I am pretty sure that this is a compiler bug, so not to worry.  However,
      as far as I can see, iwl-3945.o (the only user) and iwl3945-base.o are
      always linked into the same module, so the EXPORT_SYMBOL (which causes
      the problem) should not be needed.  Correct?

      Bluetooth: Fix connection establishment with low security requirement · 3fdca1e1
      Marcel Holtmann authored
      
      
      The Bluetooth 2.1 specification introduced four different security modes
      that can be mapped using Legacy Pairing and Simple Pairing. With the
      usage of Simple Pairing it is required that all connections (except
      the ones for SDP) are encrypted. So even the low security requirement
      mandates an encrypted connection when using Simple Pairing. When using
      Legacy Pairing (for Bluetooth 2.0 devices and older) this is not required
      since it causes interoperability issues.
      
      To support this properly the low security requirement translates into
      different host controller transactions depending if Simple Pairing is
      supported or not. However in case of Simple Pairing the command to
      switch on encryption after a successful authentication is not triggered
      for the low security mode. This patch fixes this and actually makes
      the logic to differentiate between Simple Pairing and Legacy Pairing
      a lot simpler.

      Bluetooth: Add different pairing timeout for Legacy Pairing · 052b30b0
      Marcel Holtmann authored
      
      
      The Bluetooth stack uses a reference counting for all established ACL
      links and if no user (L2CAP connection) is present, the link will be
      terminated to save power. The problem part is the dedicated pairing
      when using Legacy Pairing (Bluetooth 2.0 and before). At that point
      no user is present and pairing attempts will be disconnected within
      10 seconds or less. In previous kernel version this was not a problem
      since the disconnect timeout wasn't triggered on incoming connections
      for the first time. However this caused issues with broken host stacks
      that kept the connections around after dedicated pairing. When the
      support for Simple Pairing got added, the link establishment procedure
      needed to be changed and now causes issues when using Legacy Pairing
      
      When using Simple Pairing it is possible to do a proper reference
      counting of ACL link users. With Legacy Pairing this is not possible
      since the specification is unclear in some areas and too many broken
      Bluetooth devices have already been deployed. So instead of trying to
      deal with all the broken devices, a special pairing timeout will be
      introduced that increases the timeout to 60 seconds when pairing is
      triggered.
      
      If a broken devices now puts the stack into an unforeseen state, the
      worst that happens is the disconnect timeout triggers after 120 seconds
      instead of 4 seconds. This allows successful pairings with legacy and
      broken devices now.
