      tcm_fc: Do not free tpg structure during wq allocation failure · 06383f10
      Mark Rustad authored
      Avoid freeing a registered tpg structure if an alloc_workqueue call
      fails.  This fixes a bug where the failure was leaking memory associated
      with se_portal_group setup during the original core_tpg_register() call.

      tcm_fc: Add abort flag for gracefully handling exchange timeout · e1c40382
      Mark Rustad authored
      Add abort flag and use it to terminate processing when an exchange
      is timed out or is reset. The abort flag is used in place of the
      transport_generic_free_cmd function call in the reset and timeout
      cases, because calling that function in that context would free
      memory that was in use. The aborted flag allows the lifetime to
      be managed in a more normal way, while truncating the processing.
      This change eliminates a source of memory corruption which
      manifested in a variety of ugly ways.

      Make the "word-at-a-time" helper functions more commonly usable · f68e556e
      Linus Torvalds authored
      I have a new optimized x86 "strncpy_from_user()" that will use these
      same helper functions for all the same reasons the name lookup code uses
      them.  This is preparation for that.
      This moves them into an architecture-specific header file.  It's
      architecture-specific for two reasons:
       - some of the functions are likely to want architecture-specific
         implementations.  Even if the current code happens to be "generic" in
         the sense that it should work on any little-endian machine, it's
         likely that the "multiply by a big constant and shift" implementation
         is less than optimal for an architecture that has a guaranteed fast
         bit count instruction, for example.
       - I expect that if architectures like sparc want to start playing
         around with this, we'll need to abstract out a few more details (in
         particular the actual unaligned accesses).  So we're likely to have
         more architecture-specific stuff if non-x86 architectures start using
         (and if it turns out that non-x86 architectures don't start using
         this, then having it in an architecture-specific header is still the
         right thing to do, of course)

      cpuidle: Fix panic in CPU off-lining with no idle driver · ee01e663
      Toshi Kani authored
      Fix a NULL pointer dereference panic in cpuidle_play_dead() during
      CPU off-lining when no cpuidle driver is registered.  A cpuidle
      driver may be registered at boot-time based on CPU type.  This patch
      allows an off-lined CPU to enter HLT-based idle in this condition.

          fix from Thomas Graf.
       9) Add missing address change event emissions to bonding, from Shlomo
      10) /proc/net/dev regressed because it uses a private offset to track
          where we are in the hash table, but this doesn't track the offset
          pullback that the seq_file code does resulting in some entries being
          missed in large dumps.
          Fix from Eric Dumazet.
      11) do_tcp_sendpage() unloads the send queue way too fast, because it
          invokes tcp_push() when it shouldn't.  Let the natural sequence
          generated by the splice paths, and the assosciated MSG_MORE
          settings, guide the tcp_push() calls.
          Otherwise what goes out of TCP is spaghetti and doesn't batch
          effectively into GSO/TSO clusters.
          From Eric Dumazet.
      12) Once we put a SKB into either the netlink receiver's queue or a
          socket error queue, it can be consumed and freed up, therefore we
          cannot touch it after queueing it like that.
          Fixes from Eric Dumazet.
      13) PPP has this annoying behavior in that for every transmit call it
          immediately stops the TX queue, then calls down into the next layer
          to transmit the PPP frame.
          But if that next layer can take it immediately, it just un-stops the
          TX queue right before returning from the transmit method.
          Besides being useless work, it makes several facilities unusable, in
          particular things like the equalizers.  Well behaved devices should
          only stop the TX queue when they really are full, and in PPP's case
          when it gets backlogged to the downstream device.
          David Woodhouse therefore fixed PPP to not stop the TX queue until
          it's downstream can't take data any more.
      14) IFF_UNICAST_FLT got accidently lost in some recent stmmac driver
          changes, re-add.  From Marc Kleine-Budde.
