  • 647bd61a5   UDF: check for allocated memory for inode data ... Browse Code »

    This patch adds checking for granted memory while filling up inode data to
    prevent possible NULL pointer usage. If there is not enough memory to fill
    inode data we just mark it as "bad". Also some whitespace cleanup.

  • 74584ae50   udf: fix possible leakage of blocks ... Browse Code »

    We have to take care that when we call udf_discard_prealloc() from
    udf_clear_inode() we have to write inode ourselves afterwards (otherwise,
    some changes might be lost leading to leakage of blocks, use of free blocks
    or improperly aligned extents).

    Also udf_discard_prealloc() does two different things - it removes
    preallocated blocks and truncates the last extent to exactly match i_size.
    We move the latter functionality to udf_truncate_tail_extent(), call
    udf_discard_prealloc() when last reference to a file is dropped and call
    udf_truncate_tail_extent() when inode is being removed from inode cache
    (udf_clear_inode() call).

    We cannot call udf_truncate_tail_extent() earlier as subsequent open+write
    would find the last block of the file mapped and happily write to the end
    of it, although the last extent says it's shorter.

  • 85d71244f   Fix possible UDF data corruption ... Browse Code »

    update_next_aext() could possibly rewrite values in elen and eloc, possibly
    leading to data corruption when rewriting a file. Use temporary variables
    instead. Also advance cur_epos as it can also point to an indirect extent
    pointer.

    Use sector_t and loff_t for file offsets in UDF filesystem. Otherwise an
    overflow may occur for long files. Also make inode_bmap() return offset in
    the extent in number of blocks instead of number of bytes - for most
    callers this is more convenient.

  • ba52de123   [PATCH] inode-diet: Eliminate i_blksize from the inode structure ... Browse Code »

    This eliminates the i_blksize field from struct inode. Filesystems that want
    to provide a per-inode st_blksize can do so by providing their own getattr
    routine instead of using the generic_fillattr() function.

    Note that some filesystems were providing pretty much random (and incorrect)
    values for i_blksize.

  • 0e6b3e5e9   [PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget options ... Browse Code »

    As Pekka Enberg pointed out, with the if still following the else, you can
    still get a null uid written to the disk if you specify a default uid= without
    uid=forget. In other words, if the desktop user is uid=1000 and the mount
    option uid=1000 is given ( which is done on ubuntu automatically and probably
    other distributions that use hal ), then if any other user besides uid 1000
    owns a file then a 0 will be written to the media as the owning uid instead.

  • 4d6660eb3   [PATCH] udf: fix uid/gid options and add uid/gid=ignore and forget options ... Browse Code »

    Fix a bug in udf where it would write uid/gid = 0 to the disk for files
    owned by the id given with the uid=/gid= mount options. It also adds 4 new
    mount options: uid/gid=forget and uid/gid=ignore. Without any options the
    id in core and on disk always match. Giving uid/gid=nnn specifies a
    default ID to be used in core when the on disk ID is -1. uid/gid=ignore
    forces the in core ID to allways be used no matter what the on disk ID is.
    uid/gid=forget forces the on disk ID to always be written out as -1.

    The use of these options allows you to override ownerships on a disk or
    disable ownwership information from being written, allowing the media to be
    used portably between different computers and possibly different users
    without permissions issues that would require root to correct.

  • fef266580   [PATCH] update filesystems for new delete_inode behavior ... Browse Code »

    Update the file systems in fs/ implementing a delete_inode() callback to
    call truncate_inode_pages(). One implementation note: In developing this
    patch I put the calls to truncate_inode_pages() at the very top of those
    filesystems delete_inode() callbacks in order to retain the previous
    behavior. I'm guessing that some of those could probably be optimized.

    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!
