    ACL from disk after having a cache miss. This means we can replace the ACL

  • e77819e57   vfs: move ACL cache lookup into generic code ... Browse Code »

    This moves logic for checking the cached ACL values from low-level
    filesystems into generic code. The end result is a streamlined ACL
    check that doesn't need to load the inode->i_op->check_acl pointer at
    all for the common cached case.

    The filesystems also don't need to check for a non-blocking RCU walk
    case in their acl_check() functions, because that is all handled at a
    VFS layer.

  • 02c24a821   fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlers ... Browse Code »

    Btrfs needs to be able to control how filemap_write_and_wait_range() is called
    in fsync to make it less of a painful operation, so push down taking i_mutex and
    the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some
    file systems can drop taking the i_mutex altogether it seems, like ext3 and
    ocfs2. For correctness sake I just pushed everything down in all cases to make
    sure that we keep the current behavior the same for everybody, and then each
    individual fs maintainer can make up their mind about what to do from there.
    Thanks,

  • aacfc19c6   fs: simplify the blockdev_direct_IO prototype ... Browse Code »

    Simple filesystems always pass inode->i_sb_bdev as the block device
    argument, and never need a end_io handler. Let's simply things for
    them and for my grepping activity by dropping these arguments. The
    only thing not falling into that scheme is ext4, which passes and
    end_io handler without needing special flags (yet), but given how
    messy the direct I/O code there is use of __blockdev_direct_IO
    in one instead of two out of three cases isn't going to make a large
    difference anyway.

    Let filesystems handle waiting for direct I/O requests themselves instead
    of doing it beforehand. This means filesystem-specific locks to prevent
    new dio referenes from appearing can be held. This is important to allow
    generalizing i_dio_count to non-DIO_LOCKING filesystems.

  • 9d8f13ba3   security: new security_inode_init_security API adds function callback ... Browse Code »

    This patch changes the security_inode_init_security API by adding a
    filesystem specific callback to write security extended attributes.
    This change is in preparation for supporting the initialization of
    multiple LSM xattrs and the EVM xattr. Initially the callback function
    walks an array of xattrs, writing each xattr separately, but could be
    optimized to write multiple xattrs at once.

    For existing security_inode_init_security() calls, which have not yet
    been converted to use the new callback function, such as those in
    reiserfs and ocfs2, this patch defines security_old_inode_init_security().

  • 4e299c1d9   ext2: fix error msg when mounting fs with too-large blocksize ... Browse Code »

    When ext2 mounts a filesystem, it attempts to set the block device
    blocksize with a call to sb_set_blocksize, which can fail for
    several reasons. The current failure message in ext2 prints:

    EXT2-fs (loop1): error: blocksize is too small

    which is not correct in all cases. This can be demonstrated
    by creating a filesystem with

    # mkfs.ext2 -b 8192

    on a 4k page system, and attempting to mount it.

    Change the error message to a more generic:

    EXT2-fs (loop1): bad blocksize 8192

    to match the error message in ext3.

  • e8a80c6f7   ext2: Fix link count corruption under heavy link+rename load ... Browse Code »

    vfs_rename_other() does not lock renamed inode with i_mutex. Thus changing
    i_nlink in a non-atomic manner (which happens in ext2_rename()) can corrupt
    it as reported and analyzed by Josh.

    In fact, there is no good reason to mess with i_nlink of the moved file.
    We did it presumably to simulate linking into the new directory and unlinking
    from an old one. But the practical effect of this is disputable because fsck
    can possibly treat file as being properly linked into both directories without
    writing any error which is confusing. So we just stop increment-decrement
    games with i_nlink which also fixes the corruption.

  • 2a7dba391   fs/vfs/security: pass last path component to LSM on inode creation ... Browse Code »

    SELinux would like to implement a new labeling behavior of newly created
    inodes. We currently label new inodes based on the parent and the creating
    process. This new behavior would also take into account the name of the
    new object when deciding the new label. This is not the (supposed) full path,
    just the last component of the path.

    This is very useful because creating /etc/shadow is different than creating
    /etc/passwd but the kernel hooks are unable to differentiate these
    operations. We currently require that userspace realize it is doing some
    difficult operation like that and than userspace jumps through SELinux hoops
    to get things set up correctly. This patch does not implement new
    behavior, that is obviously contained in a seperate SELinux patch, but it
    does pass the needed name down to the correct LSM hook. If no such name
    exists it is fine to pass NULL.
