      x86: clean up alternative.h · edc953fa
      Mathieu Desnoyers authored
      Alternative header duplicates assembly that could be merged in
      one single macro.  Merging this into this macro also allows to
      directly declare ALTERNATIVE() statements within assembly code.
      
      Uses a __stringify() of the feature bits rather than passing a
      "i" operand.  Leave the old %0 operand as-is (set to 0), unused
      to stay compatible with API.
      
      (v2: tab alignment fixes)

      ext4: Do not try to validate extents on special files · c4b5a614
      Theodore Ts'o authored
      The EXTENTS_FL flag should never be set on special files, but if it
      is, don't bother trying to validate that the extents tree is valid,
      since only files, directories, and non-fast symlinks will ever have an
      extent data structure.  We perhaps should flag the filesystem as being
      corrupted if we see a special file (named pipes, device nodes, Unix
      domain sockets, etc.) with the EXTENTS_FL flag, but e2fsck doesn't
      currently check this case, so we'll just ignore this for now, since
      it's harmless.
      
      Without this fix, a special device with the extents flag is flagged as
      an error by the kernel, so it is impossible to access or delete the
      inode, but e2fsck doesn't see it as a problem, leading to
      confused/frustrated users.

      PM/Hibernate: Fix waiting for image device to appear on resume · 0c8454f5
      Rafael J. Wysocki authored
      Commit c7510859 ("PM/Hibernate: Wait for
      SCSI devices scan to complete during resume") added a call to
      scsi_complete_async_scans() to software_resume(), so that it waited for
      the SCSI scanning to complete, but the call was added at a wrong place.
      
      Namely, it should have been added after wait_for_device_probe(), which
      is called only if the image partition hasn't been specified yet.  Also,
      it's reasonable to check if the image partition is present and only wait
      for the device probing and SCSI scanning to complete if it is not the
      case.
      
      Additionally, since noresume is checked right at the beginning of
      software_resume() and the function returns immediately if it's set, it
      doesn't make sense to check it once again later.

      ROMFS: Advance destination buffer pointer when reading from a blockdev · 4b2b0b97
      David Howells authored
      RomFS should advance the destination buffer pointer when reading data from a
      blockdev source (the data may be split over multiple blocks, each requiring its
      own sb_read() call).  Without this, all the data is copied to the beginning of
      the output buffer.

      ROMFS: romfs_lookup() shouldn't be doing a partial name comparison · 84baf74b
      David Howells authored
      romfs_lookup() should be using a routine akin to strcmp() on the backing store,
      rather than one akin to strncmp().  If it uses the latter, it's liable to match
      /bin/shutdown when looking up /bin/sh.

      lib: find_last_bit.o needed by a module only, move it from lib to obj · a5422a51
      Fred Isaman authored
      Currently, although find_last_bit is EXPORTed, it is statically linked
      with the kernel and is referenced only under CONFIG_SMP.
      
      When CONFIG_SMP is undefined and find_last_bit is referenced only by
      modules, linking fails with:
      
        ERROR: "find_last_bit" [fs/nfs/nfs.ko] undefined!

      virtio-rng: Remove false BUG for spurious callbacks · e5b89542
      Christian Borntraeger authored
      The virtio-rng drivers checks for spurious callbacks. Since
      callbacks can be implemented via shared interrupts (e.g. PCI) this
      could lead to guest kernel oopses with lots of virtio devices.

      ext4: Ignore i_file_acl_high unless EXT4_FEATURE_INCOMPAT_64BIT is present · a9e81742
      Theodore Ts'o authored
      Don't try to look at i_file_acl_high unless the INCOMPAT_64BIT feature
      bit is set.  The field is normally zero, but older versions of e2fsck
      didn't automatically check to make sure of this, so in the spirit of
      "be liberal in what you accept", don't look at i_file_acl_high unless
      we are using a 64-bit filesystem.

      ext4: Fix softlockup caused by illegal i_file_acl value in on-disk inode · 485c26ec
      Theodore Ts'o authored
      If the block containing external extended attributes (which is stored
      in i_file_acl and i_file_acl_high) is larger than the on-disk
      filesystem, the process which tried to access the extended attributes
      will endlessly issue kernel printks complaining that
      "__find_get_block_slow() failed", locking up that CPU until the system
      is forcibly rebooted.
      
      So when we read in the inode, make sure the i_file_acl value is legal,
      and if not, flag the filesystem as being corrupted.
