      ath9k: stop on rates with idx -1 in ath9k rate control's .tx_status · 2504a642
      Pavel Roskin authored
      Rate control algorithms are supposed to stop processing when they
      encounter a rate with the index -1.  Checking for rate->count not being
      zero is not enough.
      
      Allowing a rate with negative index leads to memory corruption in
      ath_debug_stat_rc().
      
      One consequence of the bug is discussed at
      https://bugzilla.redhat.com/show_bug.cgi?id=768639

      mwifiex: clear previous security setting during association · 6670f15b
      Amitkumar Karwar authored
      
      
      Driver maintains different flags for WEP, WPA, WPA2 security modes.
      Appropriate flag is set using security information provided in
      connect request. mwifiex_is_network_compatible() routine uses them
      to check if driver's setting is compatible with AP. Association is
      aborted if the routine fails.
      
      For some corner cases, it is observed that association is failed
      even for valid security information based on association history.
      This patch fixes the problem by clearing previous security setting
      during each association.
      
      We should set WEP key provided in connect request as default tx key.
      This missing change is also added here.

      mac80211: do not call rate control .tx_status before .rate_init · 216c57b2
      Felix Fietkau authored
      
      
      Most rate control implementations assume .get_rate and .tx_status are only
      called once the per-station data has been fully initialized.
      minstrel_ht crashes if this assumption is violated.

      mac80211: call rate control only after init · 4b5a433a
      Johannes Berg authored
      
      
      There are situations where we don't have the
      necessary rate control information yet for
      station entries, e.g. when associating. This
      currently doesn't really happen due to the
      dummy station handling; explicitly disabling
      rate control when it's not initialised will
      allow us to remove dummy stations.

      Bluetooth: Fix possible use after free in delete path · 24d2b8c0
      Ulisses Furquim authored
      
      
      We need to use the _sync() version for cancelling the info and security
      timer in the L2CAP connection delete path. Otherwise the delayed work
      handler might run after the connection object is freed.

      Bluetooth: Remove usage of __cancel_delayed_work() · 6de32750
      Ulisses Furquim authored
      
      
      __cancel_delayed_work() is being used in some paths where we cannot
      sleep waiting for the delayed work to finish. However, that function
      might return while the timer is running and the work will be queued
      again. Replace the calls with safer cancel_delayed_work() version
      which spins until the timer handler finishes on other CPUs and
      cancels the delayed work.

      This issue has been brought up earlier here:
      
      https://lkml.org/lkml/2011/5/21/127
      
      The issue appears to be the rfcomm_session_put in rfcomm_recv_ua. This
      operation doesn't seem be to required as for the non-initiator case we
      have the rfcomm_process_rx doing an explicit put and in the initiator
      case the last dlc_unlink will drive the reference counter to 0.
      
      There have been several attempts to fix these issue:
      
      6c2718da Bluetooth: Do not call rfcomm_session_put() for RFCOMM UA on closed socket
      683d949a
      
       Bluetooth: Never deallocate a session when some DLC points to it
      
      but AFAICS they do not fix the issue just make it harder to reproduce.

      Bluetooth: silence lockdep warning · b5a30dda

      Since bluetooth uses multiple protocols types, to avoid lockdep

      protocol type).
      
      This is already done in bt_sock_create but it misses a couple of cases
      when new connections are created. This patch corrects that to fix the

      Bluetooth: l2cap_set_timer needs jiffies as timeout value · 6e1da683
      Andrzej Kaczmarek authored
      
      
      After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
      value to be specified in jiffies but constants defined in miliseconds
      are used. This makes timeouts unreliable when CONFIG_HZ is not set to
      1000.
      
      __set_chan_timer macro still uses jiffies as input to avoid multiple
      conversions from/to jiffies for sk_sndtimeo value which is already
      specified in jiffies.

      Andrzej Kaczmarek authored
      
      
      sk_sndtime value should be specified in jiffies thus initial value
      needs to be converted from miliseconds. Otherwise this timeout is
      unreliable when CONFIG_HZ is not set to 1000.

      Bluetooth: Fix l2cap conn failures for ssp devices · 18daf164
      Peter Hurley authored
      Commit 33060542
      
       fixed l2cap conn establishment for non-ssp remote
      devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
      is tested (which was always returning failure on any subsequent
      security checks).
      
      However, this broke l2cap conn establishment for ssp remote devices
      when an ACL link was already established at SDP-level security. This
      fix ensures that encryption must be pending whenever authentication
      is also pending.
