      IB/mlx4: Fix last allocated object tracking in bitmap allocator · a2cb4a98
      Roland Dreier authored
      Set last allocated object to the object after the one just allocated
      before ORing in the extra top bits.  Also handle the case where this
      wraps around.

      IB/cm: Fix stale connection detection · d998ccce
      Sean Hefty authored
      The ib_cm can incorrectly detect a stale connection (a new connection
      request for a QPN that is already connected) as a duplicate connection
      request.  Separate the handling of potential duplicate REQs from stale
      connections.

      IPoIB/cm: Fix performance regression on Mellanox · ec56dc0b
      Michael S. Tsirkin authored
      commit 518b1646 ("IPoIB/cm: Fix SRQ WR leak") introduced a severe
      performance regression on Mellanox cards, because keeping a QP in the
      error state for extended periods of time moves hardware to the slow
      path (until the QP is destroyed).  For example, MPI latency goes from
      ~3 usecs to ~7 usecs.
      
      Fix this by posting a send WR on one of the QPs that are being
      flushed, instead of using a separate drain QP that is kept in the
      error state.
      
      This fixes bug <https://bugs.openfabrics.org/show_bug.cgi?id=636>,
      reported and bisected by Scott Weitzenkamp at Cisco and debugged by
      Sasha Mikheev at Voltaire.

      IB/mthca: Fix handling of send CQE with error for QPs connected to SRQ · 8b7e1577
      Michael S. Tsirkin authored
      mthca_free_err_wqe() currently treats both send and receive CQEs
      identically if a QP is using an SRQ.  But for Tavor hardware, send
      CQEs with error can be chained together even if the RQ is part of SRQ,
      so we may miss some CQEs.
      
      Fix by following the WQE chain for all send CQEs even for non-SRQ QPs.
      
      This fixes crashes in IPoIB CM:

      USB: replace flush_workqueue with cancel_sync_work · d5d4db70
      Alan Stern authored
      This patch (as912) replaces a couple of calls to flush_workqueue()
      with cancel_sync_work() and cancel_rearming_delayed_work().  Using a
      more directed approach allows us to avoid some nasty deadlocks.  The
      prime example occurs when a first-level device (the parent is a root
      hub) is removed while at the same time the root hub gets a remote
      wakeup request.  khubd would try to flush the autosuspend workqueue
      while holding the root-hub's lock, and the remote-wakeup workqueue
      routine would be waiting to lock the root hub.
      
      The patch also reorganizes the power management portion of
      usb_disconnect(), separating it out into its own routine.  The
      autosuspend workqueue entry is cancelled immediately instead of
      waiting for the device's release routine.  In addition,
      synchronization with the autosuspend thread is carried out even for
      root hubs (an oversight in the original code).

      [PATCH] hostap: Allocate enough tailroom for TKIP · d7ea3be5
      Brandon Craig Rhodes authored
      When hostap_tx_encrypt() tries to allocate enough headroom and
      tailroom for ieee80211 encryption, it only makes enough room for the
      "mpdu" phase of the operation, but forgets about the "msdu" phase.
      (For TKIP, these two phases require, respectively, 4 and 8 bytes of
      tailroom, per the "ieee80211_crypt_tkip" structure at the bottom of
      net/ieee80211/ieee80211_crypt_tkip.c.)
