      ARM: 7598/1: net: bpf_jit_32: fix sp-relative load/stores offsets. · fe15f3f1
      Schichan Nicolas authored
      The offset must be multiplied by 4 to be sure to access the correct
      32bit word in the stack scratch space.
      
      For instance, a store at scratch memory cell #1 was generating the
      following:
      
      st	r4, [sp, #1]
      
      While the correct code for this is:
      
      st	r4, [sp, #4]
      
      To reproduce the bug (assuming your system has a NIC with the mac
      address 52:54:00:12:34:56):
      
      echo 0 > /proc/sys/net/core/bpf_jit_enable
      tcpdump -ni eth0 "ether[1] + ether[2] - ether[3] * ether[4] - ether[5] \
      	== -0x3AA" # this will capture packets as expected
      
      echo 1 > /proc/sys/net/core/bpf_jit_enable
      tcpdump -ni eth0 "ether[1] + ether[2] - ether[3] * ether[4] - ether[5] \
      	== -0x3AA" # this will not.
      
      This bug was present since the original inclusion of bpf_jit for ARM
      (ddecdfce
      
      : ARM: 7259/3: net: JIT compiler for packet filters).

      ARM: 7597/1: net: bpf_jit_32: fix kzalloc gfp/size mismatch. · 89c2e009
      Schichan Nicolas authored
      Official prototype for kzalloc is:
      
      void *kzalloc(size_t, gfp_t);
      
      The ARM bpf_jit code was having the assumption that it was:
      
      void *kzalloc(gfp_t, size);
      
      This was resulting the use of some random GFP flags depending on the
      size requested and some random overflows once the really needed size
      was more than the value of GFP_KERNEL.

      ARM: 7586/1: sp804: set cpumask to cpu_possible_mask for clock event device · ea3aacf5
      Will Deacon authored
      
      
      The SP804 driver statically initialises the cpumask of the clock event
      device to be cpu_all_mask, which is derived from the compile-time
      constant NR_CPUS. This breaks SMP_ON_UP systems where the interrupt
      controller handling the sp804 doesn't have the irq_set_affinity callback
      on the irq_chip, because the common timer code fails to identify the
      device as cpu-local and ends up treating it as a broadcast device
      instead.
      
      This patch fixes the problem by using cpu_possible_mask at runtime,
      which will correctly represent the possible CPUs when SMP_ON_UP is being
      used.

      futex: avoid wake_futex() for a PI futex_q · aa10990e
      Darren Hart authored
      
      
      Dave Jones reported a bug with futex_lock_pi() that his trinity test
      exposed.  Sometime between queue_me() and taking the q.lock_ptr, the
      lock_ptr became NULL, resulting in a crash.
      
      While futex_wake() is careful to not call wake_futex() on futex_q's with
      a pi_state or an rt_waiter (which are either waiting for a
      futex_unlock_pi() or a PI futex_requeue()), futex_wake_op() and
      futex_requeue() do not perform the same test.
      
      Update futex_wake_op() and futex_requeue() to test for q.pi_state and
      q.rt_waiter and abort with -EINVAL if detected.  To ensure any future
      breakage is caught, add a WARN() to wake_futex() if the same condition
      is true.
      
      This fix has seen 3 hours of testing with "trinity -c futex" on an
      x86_64 VM with 4 CPUS.

      writeback: put unused inodes to LRU after writeback completion · 4eff96dd
      Jan Kara authored
      Commit 169ebd90
      
       ("writeback: Avoid iput() from flusher thread")
      removed iget-iput pair from inode writeback.  As a side effect, inodes
      that are dirty during iput_final() call won't be ever added to inode LRU
      (iput_final() doesn't add dirty inodes to LRU and later when the inode
      is cleaned there's noone to add the inode there).  Thus inodes are
      effectively unreclaimable until someone looks them up again.
      
      The practical effect of this bug is limited by the fact that inodes are
      pinned by a dentry for long enough that the inode gets cleaned.  But
      still the bug can have nasty consequences leading up to OOM conditions
      under certain circumstances.  Following can easily reproduce the
      problem:
      
        for (( i = 0; i < 1000; i++ )); do
          mkdir $i
          for (( j = 0; j < 1000; j++ )); do
            touch $i/$j
            echo 2 > /proc/sys/vm/drop_caches
          done
        done
      
      then one needs to run 'sync; ls -lR' to make inodes reclaimable again.
      
      We fix the issue by inserting unused clean inodes into the LRU after
      writeback finishes in inode_sync_complete().

      mm: vmscan: check for fatal signals iff the process was throttled · 50694c28
      Mel Gorman authored
      Commit 5515061d
      
       ("mm: throttle direct reclaimers if PF_MEMALLOC
      reserves are low and swap is backed by network storage") introduced a
      check for fatal signals after a process gets throttled for network
      storage.  The intention was that if a process was throttled and got
      killed that it should not trigger the OOM killer.  As pointed out by
      Minchan Kim and David Rientjes, this check is in the wrong place and too
      broad.  If a system is in am OOM situation and a process is exiting, it
      can loop in __alloc_pages_slowpath() and calling direct reclaim in a
      loop.  As the fatal signal is pending it returns 1 as if it is making
      forward progress and can effectively deadlock.
      
      This patch moves the fatal_signal_pending() check after throttling to
      throttle_direct_reclaim() where it belongs.  If the process is killed
      while throttled, it will return immediately without direct reclaim
      except now it will have TIF_MEMDIE set and will use the PFMEMALLOC
      reserves.
      
      Minchan pointed out that it may be better to direct reclaim before
      returning to avoid using the reserves because there may be pages that
      can easily reclaim that would avoid using the reserves.  However, we do
      no such targetted reclaim and there is no guarantee that suitable pages
      are available.  As it is expected that this throttling happens when
      swap-over-NFS is used there is a possibility that the process will
      instead swap which may allocate network buffers from the PFMEMALLOC
      reserves.  Hence, in the swap-over-nfs case where a process can be
      throtted and be killed it can use the reserves to exit or it can
      potentially use reserves to swap a few pages and then exit.  This patch
      takes the option of using the reserves if necessary to allow the process
      exit quickly.
      
      If this patch passes review it should be considered a -stable candidate
      for 3.6.

      Revert "mm: remove __GFP_NO_KSWAPD" · 82b212f4
      Mel Gorman authored
      
      
      With "mm: vmscan: scale number of pages reclaimed by reclaim/compaction
      based on failures" reverted, Zdenek Kabelac reported the following
      
        Hmm,  so it's just took longer to hit the problem and observe
        kswapd0 spinning on my CPU again - it's not as endless like before -
        but still it easily eats minutes - it helps to	turn off  Firefox
        or TB  (memory hungry apps) so kswapd0 stops soon - and restart
        those apps again.  (And I still have like >1GB of cached memory)
      
        kswapd0         R  running task        0    30      2 0x00000000
        Call Trace:
          preempt_schedule+0x42/0x60

          prune_super+0x149/0x1b0
          shrink_slab+0xba/0x510
      
      The sysrq+m indicates the system has no swap so it'll never reclaim
      anonymous pages as part of reclaim/compaction.  That is one part of the
      problem but not the root cause as file-backed pages could also be
      reclaimed.
      
      The likely underlying problem is that kswapd is woken up or kept awake
      for each THP allocation request in the page allocator slow path.
      
      If compaction fails for the requesting process then compaction will be
      deferred for a time and direct reclaim is avoided.  However, if there
      are a storm of THP requests that are simply rejected, it will still be
      the the case that kswapd is awake for a prolonged period of time as
      pgdat->kswapd_max_order is updated each time.  This is noticed by the
      main kswapd() loop and it will not call kswapd_try_to_sleep().  Instead
      it will loopp, shrinking a small number of pages and calling
      shrink_slab() on each iteration.
      
      The temptation is to supply a patch that checks if kswapd was woken for
      THP and if so ignore pgdat->kswapd_max_order but it'll be a hack and not
      backed up by proper testing.  As 3.7 is very close to release and this
      is not a bug we should release with, a safer path is to revert "mm:
      remove __GFP_NO_KSWAPD" for now and revisit it with the view to ironing
      out the balance_pgdat() logic in general.

      The all proc_map_files feature is CONFIG_CHECKPOINT_RESTORE wrapped
      (which is set to 'n' by default) so the bug doesn't affect regular
      kernels.
      
      The regression is 3.7-rc1 only as far as I can tell.

      UAPI: strip the _UAPI prefix from header guards during header installation · 56c176c9
      David Howells authored
      
      
      Strip the _UAPI prefix from header guards during header installation so
      that any userspace dependencies aren't affected.  glibc, for example,
      checks for linux/types.h, linux/kernel.h, linux/compiler.h and
      linux/list.h by their guards - though the last two aren't actually
      exported.

       "The most important part of this is that it fixes a regression in
        Samsung NAND chip detection, introduced by some rework which went into
        3.7.  The initial fix wasn't quite complete, so it's in two parts.  In
        fact the first part is committed twice (Artem committed his own copy
        of the same patch) and I've merged Artem's tree into mine which
        already had that fix.
      
        I'd have recommitted that to make it somewhat cleaner, but figured by
        this point in the release cycle it was better to merge *exactly* the
        commits which have been in linux-next.
      
        If I'd recommitted, I'd also omit the sparse warning fix.  But it's
        there, and it's harmless — just marking one function as 'static' in
        onenand code.

      of/address: sparc: Declare of_iomap as an extern function for sparc again · 0e622d39
      Andreas Larsson authored and Grant Likely's avatar Grant Likely committed
      This bug-fix makes sure that of_iomap is defined extern for sparc so that the
      sparc-specific implementation of_iomap is once again used when including
      include/linux/of_address.h in a sparc context. OF_GPIO that is now available for
      sparc relies on this.
      
      The bug was inadvertently introduced in a850a755, "of/address: add empty static
      inlines for !CONFIG_OF", that added a static dummy inline for of_iomap when
      !CONFIG_OF_ADDRESS. However, CONFIG_OF_ADDRESS is never defined for sparc, but
      there is a sparc-specific implementation /arch/sparc/kernel/of_device_common.c.
      
      This fix takes the same approach as 0bce04be
      
       that solved the equivalent problem
      for of_address_to_resource.

      dev_pm_qos_add_request() can return 0, 1, or a negative error code,
      therefore the correct error test is "if (error < 0)." Checking just for
      non-zero return code leads to erroneous setting of the req->dev pointer
      to NULL, which then leads to a repeated call to
      dev_pm_qos_add_ancestor_request() in st1232_ts_irq_handler(). This in turn
      leads to an Oops, when the I2C host adapter is unloaded and reloaded again
      because of the inconsistent state of its QoS request list.
