    It's reasonable to have headers that include all necessary definitions. So fix
    this by including fs.h into ext2_fs.h.

  • ef8b64618   ext2: tighten restrictions on inode flags ... Browse Code »

    At the moment there are few restrictions on which flags may be set on
    which inodes. Specifically DIRSYNC may only be set on directories and
    IMMUTABLE and APPEND may not be set on links. Tighten that to disallow
    TOPDIR being set on non-directories and only NODUMP and NOATIME to be set
    on non-regular file, non-directories.

    Introduces a flags masking function which masks flags based on mode and
    use it during inode creation and when flags are set via the ioctl to
    facilitate future consistency.

  • 0e090f1e0   ext2: don't inherit inappropriate inode flags from parent ... Browse Code »

    At present BTREE/INDEX is the only flag that new ext2 inodes do NOT
    inherit from their parent. In addition prevent the flags DIRTY, ECOMPR,
    INDEX, IMAGIC and TOPDIR from being inherited. List inheritable flags
    explicitly to prevent future flags from accidentally being inherited.

    This fixes the TOPDIR flag inheritance bug reported at
    http://bugzilla.kernel.org/show_bug.cgi?id=9866.

    In commit a686cd898bd999fd026a51e90fb0a3410d258ddb:

    "Val's cross-port of the ext3 reservations code into ext2."

    include/linux/ext2_fs.h got a new function whose return value is only
    defined if __KERNEL__ is defined. Putting #ifdef __KERNEL__ around the
    function seems to help, patch below.

  • 89910cccb   ext2: avoid rec_len overflow with 64KB block size ... Browse Code »

    With 64KB blocksize, a directory entry can have size 64KB which does not
    fit into 16 bits we have for entry length. So we store 0xffff instead and
    convert the value when read from / written to disk.

  • 8fc2751be   [PATCH] disk quotas fail when /etc/mtab is symlinked to /proc/mounts ... Browse Code »

    If /etc/mtab is a regular file all of the mount options (of a file system)
    are written to /etc/mtab by the mount command. The quota tools look there
    for the quota strings for their operation. If, however, /etc/mtab is a
    symlink to /proc/mounts (a "good thing" in some environments) the tools
    don't write anything - they assume the kernel will take care of things.

    While the quota options are sent down to the kernel via the mount system
    call and the file system codes handle them properly unfortunately there is
    no code to echo the quota strings into /proc/mounts and the quota tools
    fail in the symlink case.

    The attached patchs modify the EXT[2|3] and JFS codes to add the necessary
    hooks. The show_options function of each file system in these patches
    currently deal with only those things that seemed related to quotas;
    especially in the EXT3 case more can be done (later?).

    Jan Kara also noted the difficulty in moving these changes above the FS
    codes responding similarly to myself to Andrew's comment about possible
    VFS migration. Issue summary:

    - FS codes have to process the entire string of options anyway.

    - Only FS codes that use quotas must have a show_options function (for
    quotas to work properly) however quotas are only used in a small number
    of FS.

    - Since most of the quota using FS support other options these FS codes
    should have the a show_options function to show those options - and the
    quota echoing becomes virtually negligible.

    Based on feedback I have modified my patches from the original:

    JFS a missing patch has been restored to the posting
    EXT[2|3] and JFS always use the show_options function
    - Each FS has at least one FS specific option displayed
    - QUOTA output is under a CONFIG_QUOTA ifdef
    - a follow-on patch will add a multitude of options for each FS
    EXT[2|3] and JFS "quota" is treated as "usrquota"
    EXT3 journalled data check for journalled quota removed
    EXT[2|3] mount when quota specified but not compiled in

    - no changes from my original patch. I tested the patch and the codes
    warn but

    - still mount. With all due respection I believe the comments
    otherwise were a

    - misread of the patch. Please reread/test and comment. XFS patch
    removed - the XFS team already made the necessary changes EXT3 mixing
    old and new quotas are handled differently (not purely exclusive)

    - if old and new quotas for the same type are used together the old
    type is silently depricated for compatability (e.g. usrquota and
    usrjquota)

    - mixing of old and new quotas is an error (e.g. usrjquota and
    grpquota)

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
