      John David Anglin authored
      The __ldcw macro has a problem when its argument needs to be reloaded from
      memory. The output memory operand and the input register operand both need to
      be reloaded using a register in class R1_REGS when generating 64-bit code.
      This fails because there's only a single register in the class. Instead, use a
      memory clobber. This also makes the __ldcw macro a compiler memory barrier.

      audit: restore AUDIT_LOGINUID unset ABI · 041d7b98
      Richard Guy Briggs authored
      A regression was caused by commit 780a7654:
      	 audit: Make testing for a valid loginuid explicit.
      (which in turn attempted to fix a regression caused by e1760bd5)
      
      When audit_krule_to_data() fills in the rules to get a listing, there was a
      missing clause to convert back from AUDIT_LOGINUID_SET to AUDIT_LOGINUID.
      
      This broke userspace by not returning the same information that was sent and
      expected.
      
      The rule:
      	auditctl -a exit,never -F auid=-1
      gives:
      	auditctl -l
      		LIST_RULES: exit,never f24=0 syscall=all
      when it should give:
      		LIST_RULES: exit,never auid=-1 (0xffffffff) syscall=all
      
      Tag it so that it is reported the same way it was set.  Create a new
      private flags audit_krule field (pflags) to store it that won't interact with
      the public one from the API.

      arm64: kernel: fix __cpu_suspend mm switch on warm-boot · f43c2718
      Lorenzo Pieralisi authored
      On arm64 the TTBR0_EL1 register is set to either the reserved TTBR0
      page tables on boot or to the active_mm mappings belonging to user space
      processes, it must never be set to swapper_pg_dir page tables mappings.
      
      When a CPU is booted its active_mm is set to init_mm even though its
      TTBR0_EL1 points at the reserved TTBR0 page mappings. This implies
      that when __cpu_suspend is triggered the active_mm can point at
      init_mm even if the current TTBR0_EL1 register contains the reserved
      TTBR0_EL1 mappings.
      
      Therefore, the mm save and restore executed in __cpu_suspend might
      turn out to be erroneous in that, if the current->active_mm corresponds
      to init_mm, on resume from low power it ends up restoring in the
      TTBR0_EL1 the init_mm mappings that are global and can cause speculation
      of TLB entries which end up being propagated to user space.
      
      This patch fixes the issue by checking the active_mm pointer before
      restoring the TTBR0 mappings. If the current active_mm == &init_mm,
      the code sets the TTBR0_EL1 to the reserved TTBR0 mapping instead of
      switching back to the active_mm, which is the expected behaviour
      corresponding to the TTBR0_EL1 settings when __cpu_suspend was entered.

      drm/tegra: Fixes for v3.19-rc1
      
      This is a set of fixes for two regressions and one bug in the IOMMU
      mapping code. It turns out that all of these issues turn up primarily
      on Tegra30 hardware. The IOMMU mapping bug only manifests on buffers
      that aren't multiples of the page size. I happened to be testing HDMI
      with 1080p while writing the code and framebuffers for that happen to
      fit exactly within 2025 pages of 4 KiB each.
      
      One of the regressions is caused by the IOMMU code allocating pages from
      shmem which can have associated cache lines. If the pages aren't flushed
      then these cache lines may be flushed later on and cause framebuffer
      corruption. I'm not sure why I didn't see this before. Perhaps the board
      that I was using had enough RAM so that the pages shmem would hand out
      had a better chance of being unused. Or maybe I didn't look too closely.
      The fix for this is to fake up an SG table so that it can be passed to
      the DMA API. Ideally this would use drm_clflush_*(), but implementing
      that for ARM causes DRM to fail to build as a module since some of the
      low-level cache maintenance functions aren't exported. Hopefully we can
      get a suitable API exported on ARM for the next release.
      
      The second regression is caused by a mismatch between the hardware pipe
      number and the CRTC's DRM index. These were used inconsistently, which
      could cause one code location to call drm_vblank_get() with a different
      pipe than the corresponding drm_vblank_put(), thereby causing the
      reference count to become unbalanced. Alexandre also reported a possible
      race condition related to this, which this series also fixes.

      audit: correctly record file names with different path name types · 4a928436
      Paul Moore authored
      There is a problem with the audit system when multiple audit records
      are created for the same path, each with a different path name type.
      The root cause of the problem is in __audit_inode() when an exact
      match (both the path name and path name type) is not found for a
      path name record; the existing code creates a new path name record,
      but it never sets the path name in this record, leaving it NULL.
      This patch corrects this problem by assigning the path name to these
      newly created records.
      
      There are many ways to reproduce this problem, but one of the
      easiest is the following (assuming auditd is running):
      
        # mkdir /root/tmp/test
        # touch /root/tmp/test/567
        # auditctl -a always,exit -F dir=/root/tmp/test
        # touch /root/tmp/test/567
      
      Afterwards, or while the commands above are running, check the audit
      log and pay special attention to the PATH records.  A faulty kernel
      will display something like the following for the file creation:
      
        type=SYSCALL msg=audit(1416957442.025:93): arch=c000003e syscall=2
          success=yes exit=3 ... comm="touch" exe="/usr/bin/touch"
        type=CWD msg=audit(1416957442.025:93):  cwd="/root/tmp"
        type=PATH msg=audit(1416957442.025:93): item=0 name="test/"
          inode=401409 ... nametype=PARENT
        type=PATH msg=audit(1416957442.025:93): item=1 name=(null)
          inode=393804 ... nametype=NORMAL
        type=PATH msg=audit(1416957442.025:93): item=2 name=(null)
          inode=393804 ... nametype=NORMAL
      
      While a patched kernel will show the following:

      with an explanation of the problem and a patch.  While the original
      patch did have some problems (see the archive link below), it did
      demonstrate the problem and helped kickstart the fix presented here.

      arm64: Replace set_arch_dma_coherent_ops with arch_setup_dma_ops · 31dde116
      Catalin Marinas authored
      Commit a3a60f81 (dma-mapping: replace set_arch_dma_coherent_ops with
      arch_setup_dma_ops) changes the of_dma_configure() arch dma_ops callback
      to arch_setup_dma_ops but only the arch/arm code is updated. Subsequent
      commit 97890ba9 (dma-mapping: detect and configure IOMMU in
      of_dma_configure) changes the arch_setup_dma_ops() prototype further to
      handle iommu. The patch makes the corresponding arm64 changes.

      ipmi: Finish cleanup of BMC attributes · 9c633317
      Corey Minyard authored
      The previous cleanup of BMC attributes left a few holes, and if
      you run with lockdep debugging with a BMC with the proper attributes,
      you could get a warning.
      
      This patch removes all the unused attributes from the BMC structure,
      since they are all declared in the .data section now.  It makes
      the attributes all static.  It fixes the referencing of the
      attributes in a couple of cases that dynamically added the files
      depending on BMC information.

       "kernel: Provide READ_ONCE and ASSIGN_ONCE
      
        As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
        ACCESS_ONCE might fail with specific compilers for non-scalar
        accesses.
      
        Here is a set of patches to tackle that problem.
      
        The first patch introduce READ_ONCE and ASSIGN_ONCE.  If the data
        structure is larger than the machine word size memcpy is used and a
        warning is emitted.  The next patches fix up several in-tree users of
        ACCESS_ONCE on non-scalar types.
      
        This does not yet contain a patch that forces ACCESS_ONCE to work only
        on scalar types.  This is targetted for the next merge window as Linux
        next already contains new offenders regarding ACCESS_ONCE vs.
