      assoc_array: Include rcupdate.h for call_rcu() definition · 990428b8
      Pranith Kumar authored
      Include rcupdate.h header to provide call_rcu() definition. This was implicitly
      being provided by slab.h file which include srcu.h somewhere in its include
      hierarchy which in-turn included rcupdate.h.
      
      Lately, tinification effort added support to remove srcu entirely because of
      which we are encountering build errors like
      
      lib/assoc_array.c: In function 'assoc_array_apply_edit':
      lib/assoc_array.c:1426:2: error: implicit declaration of function 'call_rcu' [-Werror=implicit-function-declaration]
      cc1: some warnings being treated as errors
      
      Fix these by including rcupdate.h explicitly.

      KEYS: close race between key lookup and freeing · a3a87844
      Sasha Levin authored
      When a key is being garbage collected, it's key->user would get put before
      the ->destroy() callback is called, where the key is removed from it's
      respective tracking structures.
      
      This leaves a key hanging in a semi-invalid state which leaves a window open
      for a different task to try an access key->user. An example is
      find_keyring_by_name() which would dereference key->user for a key that is
      in the process of being garbage collected (where key->user was freed but
      ->destroy() wasn't called yet - so it's still present in the linked list).
      
      This would cause either a panic, or corrupt memory.
      
      Fixes CVE-2014-9529.

      SCSI: fix regression in scsi_send_eh_cmnd() · 511833ac
      Alan Stern authored
      Commit ac61d195 (scsi: set correct completion code in
      scsi_send_eh_cmnd()) introduced a bug.  It changed the stored return
      value from a queuecommand call, but it didn't take into account that
      the return value was used again later on.  This patch fixes the bug by
      changing the later usage.
      
      There is a big comment in the middle of scsi_send_eh_cmnd() which
      does a good job of explaining how the routine works.  But it mentions
      a "rtn = FAILURE" value that doesn't exist in the code.  This patch
      adjusts the code to match the comment (I assume the comment is right
      and the code is wrong).
      
      This fixes Bugzilla #88341.

      Currently we enable Exynos devices in the multi v7 defconfig, however, when

      audit: create private file name copies when auditing inodes · fcf22d82
      Paul Moore authored
      Unfortunately, while commit 4a928436 ("audit: correctly record file
      names with different path name types") fixed a problem where we were
      not recording filenames, it created a new problem by attempting to use
      these file names after they had been freed.  This patch resolves the
      issue by creating a copy of the filename which the audit subsystem
      frees after it is done with the string.
      
      At some point it would be nice to resolve this issue with refcounts,
      or something similar, instead of having to allocate/copy strings, but
      that is almost surely beyond the scope of a -rcX patch so we'll defer
      that for later.  On the plus side, only audit users should be impacted
      by the string copying.

      sd: tweak discard heuristics to work around QEMU SCSI issue · e461338b
      Martin K. Petersen authored
      7985090a changed the discard heuristics to give preference to the
      WRITE SAME commands that (unlike UNMAP) guarantee deterministic results.
      
      Ming Lei discovered that QEMU SCSI's WRITE SAME implementation
      internally relied on limits that were only communicated for the UNMAP
      case. And therefore discard commands backed by WRITE SAME would fail.
      
      Tweak the heuristics so we still pick UNMAP in the LBPRZ=0 case and only
      prefer the WRITE SAME variants if the device has the LBPRZ flag set.

      OMAPDSS: SDI: fix output port_num · a32442d4
      Tomi Valkeinen authored
      After the commit ef691ff4 (OMAPDSS: DT: Get source endpoint by
      matching reg-id) we look for the SDI output using the port number.
      However, the SDI driver doesn't set the port number, which causes the
      SDI display to not initialize.
      
      Fix this by setting the SDI port number to 1. We use a hardcoded value,
      as SDI was used only on OMAP3 and it's always port number 1 there.

       "First of all, the most important change is the thermal cpu cooling
        fixes.  The major fix here is to have proper sequencing between
        cpufreq layer and thermal cpu cooling registration.  A take away of
        this fix is an improvement in the thermal drivers code.  Thermal
        drivers that require cpu cooling do not need to check for cpufreq
        layer.  The requirement now is to propagate the error code, if any,
        while registering cpu cooling device.  Thanks to Viresh for
        implementing the required CPUfreq changes.
      
        Second, a new driver is introduced for int340x processor thermal
        device.  Given that int340x thermal is disabled by default, and this
        processor thermal device is only available on limited platforms, plus
        the driver does nothing but exposes some thermal limitation
        information for user space to use, thus I think it is safe to include
        it in this pull request after missing 3.19-rc2.

      mm: get rid of radix tree gfp mask for pagecache_get_page · 45f87de5
      Michal Hocko authored
      Commit 2457aec6 ("mm: non-atomically mark page accessed during page
      cache allocation where possible") has added a separate parameter for
      specifying gfp mask for radix tree allocations.
      
      Not only this is less than optimal from the API point of view because it
      is error prone, it is also buggy currently because
      grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if
      fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by
      AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then
      the radix tree allocation wouldn't obey the restriction and might
      recurse into filesystem and cause deadlocks.  This is the case for most
      filesystems unfortunately because only ext4 and gfs2 are using
      AOP_FLAG_NOFS.
      
      Let's simply remove radix_gfp_mask parameter because the allocation
      context is same for both page cache and for the radix tree.  Just make
      sure that the radix tree gets only the sane subset of the mask (e.g.  do
      not pass __GFP_WRITE).
      
      Long term it is more preferable to convert remaining users of
      AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this
      interface even further.
