  • 7e08da50c   quota: Fix maximum quota limit settings ... Browse Code »

    Currently quota format that supports 64-bit usage sets maximum quota
    limit as 2^64-1. However quota core code uses signed numbers to track
    usage and even limits themselves are stored in long long. Checking of
    maximum allowable limits worked by luck until commit 14bf61ffe6ac
    (quota: Switch ->get_dqblk() and ->set_dqblk() to use bytes as space
    units) because variable we compared with was unsigned. After that commit
    the type we compared against changed to signed and thus checks for
    maximum limits with the newest VFS quota format started to refuse any
    non-negative value. Later the problem was inadvertedly fixed by commit
    b10a08194c2b (quota: Store maximum space limit in bytes) because we
    started to compare against unsigned type as well.

    Fix possible future problems of this kind by setting maximum limits to
    2^63-1 to avoid overflow issues.

  • b10a08194   quota: Store maximum space limit in bytes ... Browse Code »

    Currently maximum space limit quota format supports is in blocks however
    since we store space limits in bytes, this is somewhat confusing. So
    store the maximum limit in bytes as well. Also rename the field to match
    the new unit and related inode field to match the new naming scheme.

  • c119c5b97   quota: Don't store flags for v2 quota format ... Browse Code »

    Currently, v2 quota format blindly stored flags from in-memory dqinfo on
    disk, although there are no flags supported. Since it is stupid to store
    flags which have no effect, just store 0 unconditionally and don't
    bother loading it from disk.

    Note that userspace could have stored some flags there via Q_SETINFO
    quotactl and then later read them (although flags have no effect) but
    I'm pretty sure noone does that (most definitely quota-tools don't and
    quota interface doesn't have too much other users).

  • 4c376dcae   userns: Convert struct dquot dq_id to be a struct kqid ... Browse Code »

    Change struct dquot dq_id to a struct kqid and remove the now
    unecessary dq_type.

    Make minimal changes to dquot, quota_tree, quota_v1, quota_v2, ext3,
    ext4, and ocfs2 to deal with the change in quota structures and
    signatures. The ocfs2 changes are larger than most because of the
    extensive tracing throughout the ocfs2 quota code that prints out
    dq_id.

    quota_tree.c:get_index is modified to take a struct kqid instead of a
    qid_t because all of it's callers pass in dquot->dq_id and it allows
    me to introduce only a single conversion.

    The rest of the changes are either just replacing dq_type with dq_id.type,
    adding conversions to deal with the change in type and occassionally
    adding qid_eq to allow quota id comparisons in a user namespace safe way.

  • fb5ffb0e1   quota: Change quota error message to print out disk and function name ... Browse Code »

    The current quota error message doesn't always print the disk name, so
    it is hard to identify the "bad" disk when quota error happens.

    This patch changes the standardized quota error message to print out disk name
    and function name. It also uses a combination of cpp macro and inline function
    to provide better type checking and to lower the text size of the message.

    [Jan Kara: Export __quota_error]
