    1

    When finding the longest extent in an AG, we read the value directly
    out of the AGF buffer without endian conversion. This will give an
    incorrect length, resulting in FITRIM operations potentially not
    trimming everything that it should.

  • c029a50d5   xfs: fix possible overflow in xfs_ioc_trim() ... Browse Code »

    In xfs_ioc_trim it is possible that computing the last allocation group
    to discard might overflow for big start & len values, because the result
    might be bigger then xfs_agnumber_t which is 32 bit long. Fix this by not
    allowing the start and end block of the range to be beyond the end of the
    file system.

    Note that if the start is beyond the end of the file system we have to
    return -EINVAL, but in the "end" case we have to truncate it to the fs
    size.

    Also introduce "end" variable, rather than using start+len which which
    might be more confusing to get right as this bug shows.

  • c59d87c46   xfs: remove subdirectories ... Browse Code »

    Use the move from Linux 2.6 to Linux 3.x as an excuse to kill the
    annoying subdirectories in the XFS source code. Besides the large
    amount of file rename the only changes are to the Makefile, a few
    files including headers with the subdirectory prefix, and the binary
    sysctl compat code that includes a header under fs/xfs/ from
    kernel/.
