      ACPI/IORT: Handle PCI aliases properly for IOMMUs · bc8648d4
      Robin Murphy 提交于
      When a PCI device has DMA quirks, we need to ensure that an upstream
      IOMMU knows about all possible aliases, since the presence of a DMA
      quirk does not preclude the device still also emitting transactions
      (e.g. MSIs) on its 'real' RID. Similarly, the rules for bridge aliasing
      are relatively complex, and some bridges may only take ownership of
      transactions under particular transient circumstances, leading again to
      multiple RIDs potentially being seen at the IOMMU for the given device.
      
      Take all this into account in iort_iommu_configure() by mapping every
      RID produced by the alias walk, not just whichever one comes out last.
      Since adding any more internal PTR_ERR() juggling would have confused me
      no end, a bit of refactoring happens in the process - we know where to
      find the ops if everything succeeded, so we're free to just pass regular
      error codes around up until then.

      ext4: make xattr inode reads faster · 9699d4f9
      Tahsin Erdogan 提交于
      ext4_xattr_inode_read() currently reads each block sequentially while
      waiting for io operation to complete before moving on to the next
      block. This prevents request merging in block layer.
      
      Add a ext4_bread_batch() function that starts reads for all blocks
      then optionally waits for them to complete. A similar logic is used
      in ext4_find_entry(), so update that code to use the new function.

      ext4: inplace xattr block update fails to deduplicate blocks · ec000220
      Tahsin Erdogan 提交于
      When an xattr block has a single reference, block is updated inplace
      and it is reinserted to the cache. Later, a cache lookup is performed
      to see whether an existing block has the same contents. This cache
      lookup will most of the time return the just inserted entry so
      deduplication is not achieved.
      
      Running the following test script will produce two xattr blocks which
      can be observed in "File ACL: " line of debugfs output:
      
        mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G
        mount /dev/sdb /mnt/sdb
      
        touch /mnt/sdb/{x,y}
      
        setfattr -n user.1 -v aaa /mnt/sdb/x
        setfattr -n user.2 -v bbb /mnt/sdb/x
      
        setfattr -n user.1 -v aaa /mnt/sdb/y

        debugfs -R 'stat x' /dev/sdb | cat
        debugfs -R 'stat y' /dev/sdb | cat
      
      This patch defers the reinsertion to the cache so that we can locate
      other blocks with the same contents.

      ext4: fix warning about stack corruption · 2df2c340
      Arnd Bergmann 提交于
      After commit 62d1034f53e3 ("fortify: use WARN instead of BUG for now"),
      we get a warning about possible stack overflow from a memcpy that
      was not strictly bounded to the size of the local variable:
      
          inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2:
      include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=]
      
      We actually had a bug here that would have been found by the warning,
      but it was already fixed last year in commit 30a9d7af ("ext4: fix
      stack memory corruption with 64k block size").
      
      This replaces the fixed-length structure on the stack with a variable-length
      structure, using the correct upper bound that tells the compiler that
      everything is really fine here. I also change the loop count to check
      for the same upper bound for consistency, but the existing code is
      already correct here.
      
      Note that while clang won't allow certain kinds of variable-length arrays
      in structures, this particular instance is fine, as the array is at the
      end of the structure, and the size is strictly bounded.

      ext4: fix dir_nlink behaviour · c7414892
      Andreas Dilger 提交于
      The dir_nlink feature has been enabled by default for new ext4
      filesystems since e2fsprogs-1.41 in 2008, and was automatically
      enabled by the kernel for older ext4 filesystems since the
      dir_nlink feature was added with ext4 in kernel 2.6.28+ when
      the subdirectory count exceeded EXT4_LINK_MAX-1.
      
      Automatically adding the file system features such as dir_nlink is
      generally frowned upon, since it could cause the file system to not be
      mountable on older kernel, thus preventing the administrator from
      rolling back to an older kernel if necessary.
      
      In this case, the administrator might also want to disable the feature
      because glibc's fts_read() function does not correctly optimize
      directory traversal for directories that use st_nlinks field of 1 to
      indicate that the number of links in the directory are not tracked by
      the file system, and could fail to traverse the full directory
      hierarchy.  Fortunately, in the past ten years very few users have
      complained about incomplete file system traversal by glibc's
      fts_read().
      
      This commit also changes ext4_inc_count() to allow i_nlinks to reach
      the full EXT4_LINK_MAX links on the parent directory (including "."
      and "..") before changing i_links_count to be 1.

      ext4: fix SEEK_HOLE/SEEK_DATA for blocksize < pagesize · fcf5ea10
      Jan Kara 提交于
      ext4_find_unwritten_pgoff() does not properly handle a situation when
      starting index is in the middle of a page and blocksize < pagesize. The
      following command shows the bug on filesystem with 1k blocksize:
      
        xfs_io -f -c "falloc 0 4k" \
                  -c "pwrite 1k 1k" \

                  -c "seek -a -r 0" foo
      
      In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
      SEEK_DATA) will return the correct result.
      
      Fix the problem by neglecting buffers in a page before starting offset.

      platform/x86: intel-vbtn: match power button on press rather than release · 946da699
      Mario Limonciello 提交于
      This fixes a problem where the system gets stuck in a loop
      unable to wakeup via power button in s2idle.
      
      The problem happens because:
       - press power button:
         - system emits 0xc0 (power press), event ignored
         - system emits 0xc1 (power release), event processed,
           emited as KEY_POWER
         - set wakeup_mode to true
         - system goes to s2idle
       - press power button
         - system emits 0xc0 (power press), wakeup_mode is true,
           system wakes
         - system emits 0xc1 (power release), event processed,
           emited as KEY_POWER
         - system goes to s2idle again
      
      To avoid this situation, process the presses (which matches what
      intel-hid does too).

      Pull ARM SoC fixes from Arnd Bergmann:
       "This comes a bit later than I planned, and as a consequence is a
        larger than it should be.
      
        Most of the changes are devicetree fixes, across lots of platforms:
        Renesas, Samsung Exynos, Marvell EBU, TI OMAP, Rockchips, Amlogic
        Meson, Sigma Desings Tango, Allwinner SUNxi and TI Davinci.
      
        Also across many platforms, I applied an older series of simple
        randconfig build fixes. This includes making the CONFIG_MTD_XIP option
        compile again, which had been broken for many years and probably has
        not been missed, but it felt wrong to just remove it completely.
      
        The only other changes are:
      
         - We enable HWSPINLOCK in defconfig to get some Qualcomm boards to
           work out of the box.
      
         - A few regression fixes for Texas Instruments OMAP2+.
      
         - A boot regression fix for the Renesas regulator quirk.

      sparc64: Fix exception handling in UltraSPARC-III memcpy. · 0ede1c40
      David S. Miller 提交于
      Mikael Pettersson reported that some test programs in the strace-4.18
      testsuite cause an OOPS.
      
      After some debugging it turns out that garbage values are returned
      when an exception occurs, causing the fixup memset() to be run with
      bogus arguments.
      
      The problem is that two of the exception handler stubs write the
      successfully copied length into the wrong register.
      
      Fixes: ee841d0a ("sparc64: Convert U3copy_{from,to}_user to accurate exception reporting.")
