  • 92b4678ef   fsnotify: drop two useless bools in the fnsotify main loop ... Browse Code »

    The fsnotify main loop has 2 bools which indicated if we processed the
    inode or vfsmount mark in that particular pass through the loop. These
    bool can we replaced with the inode_group and vfsmount_group variables
    and actually make the code a little easier to understand.

  • f72adfd54   fsnotify: fix list walk order ... Browse Code »

    Marks were stored on the inode and vfsmonut mark list in order from
    highest memory address to lowest memory address. The code to walk those
    lists thought they were in order from lowest to highest with
    unpredictable results when trying to match up marks from each. It was
    possible that extra events would be sent to userspace when inode
    marks ignoring events wouldn't get matched with the vfsmount marks.

    This problem only affected fanotify when using both vfsmount and inode
    marks simultaneously.

  • 93c3fe40c   eCryptfs: Fix encrypted file name lookup regression ... Browse Code »

    Fixes a regression caused by 21edad32205e97dc7ccb81a85234c77e760364c8

    When file name encryption was enabled, ecryptfs_lookup() failed to use
    the encrypted and encoded version of the upper, plaintext, file name
    when performing a lookup in the lower file system. This made it
    impossible to lookup existing encrypted file names and any newly created
    files would have plaintext file names in the lower file system.

    This locking path needs proper auditing but probably too late for changes at this point for 2.6.36, so lets go with the quick fix, which is to drop the lock around schedule.

    drm_mm: extract check_free_mm_node

    I've botched up the range-restriction checks. The result is usually
    an X server dying with SIGBUS in libpixman (software fallback rendering).
    Change the code to adjust the start and end for range restricted
    allocations. IMHO this even makes the code a bit clearer.

    pass a struct path to vfs_statfs
    introduced the struct path initialization, and this seems to trigger
    an Oops on my machine.

    fh_dentry field may be NULL and set later in fh_verify(), thus the
    initialization of path must be after fh_verify().

  • 7d9478429   nfsd4: fix downgrade/lock logic ... Browse Code »
    2

    If we already had a RW open for a file, and get a readonly open, we were
    piggybacking on the existing RW open. That's inconsistent with the
    downgrade logic which blows away the RW open assuming you'll still have
    a readonly open.

    Also, make sure there is a readonly or writeonly open available for
    locking, again to prevent bad behavior in downgrade cases when any RW
    open may be lost.

    It's OK for this function to return without setting filp--we do it in
    the special-stateid case.

    And there's a legitimate case where we can hit this, since we do permit
    reads on write-only stateid's.
