    xfs_quota: fall back silently if XFS_GETNEXTQUOTA fails

    After XFS_GETNEXTQUOTA feature has been merged into linux kernel and
    xfsprogs, xfs_quota use Q_XGETNEXTQUOTA for report and dump, and
    fall back to old XFS_GETQUOTA ioctl if XFS_GETNEXTQUOTA fails.

    But when XFS_GETNEXTQUOTA fails, xfs_quota print a warning as
    "XFS_GETQUOTA: Invalid argument". That's due to kernel can't
    recognize XFS_GETNEXTQUOTA ioctl and return EINVAL. At this time,
    the warning is helpless, xfs_quota just need to fall back.

    xfs_quota: only round up timer reporting > 1 day

    I was too hasty with:

    d1fe6ff xfs_quota: remove extra 30 seconds from time limit reporting

    The point of that extra 30s, turns out, was to allow the user
    to set a limit, query it, and get back what they just set, if
    it is set to more than a day.

    Without it, if we set a grace period to i.e. 3 days, and query it
    1 second later, the rounding in the time_to_string function returns
    "2 days" not "3 days" as it did before, because we are at
    2 days 23:59:59 and it essentially applies a floor() for
    brevity.  I guess this was confusing.

    (I've run into this same conundrum on my stove digital timer;
    if you set it to 10m, it blinks "10" at you twice so that you
    know what you set, then quickly flips to 9 as it counts down).

    In some cases, however (and this is the case that prompted the
    prior patch), we display a full "XYZ days hh:mm:ss" - we do this
    if the verbose flag is set, or if the timer is less than one day.
    In these cases, we should not add the 30s, because we are showing
    full time resolution to the user.

    xfs_quota: check report_mount return value

    The new call to report_mount doesn't check the return value
    like every other caller does...

    Returning 1 means it printed something; if the terse flag
    is used and there is no usage, nothing gets printed.
    If we set the NO_HEADER_FLAG anyway, then we won't see
    the header for subsequent entries as we expect.

    For example, project ID 0 has no usage in this case:

    # xfs_quota -x -c "report -a" /mnt/test
    Project quota on /mnt/test (/dev/sdb1)
                                   Blocks
    Project ID       Used       Soft       Hard    Warn/Grace
    ---------- --------------------------------------------------
    #0                  0          0          0     00 [--------]
    project          2048          4          4     00 [--none--]

    So using the terse flag results in no header when it prints
    projects with usage:

    # xfs_quota -x -c "report -t -a" /mnt/test
    project          2048          4          4     00 [--none--]

    With this fix it prints the header as expected:

    # xfs_quota -x -c "report -t -a" /mnt/test
    Project quota on /mnt/test (/dev/sdb1)
                                   Blocks
    Project ID       Used       Soft       Hard    Warn/Grace
    ---------- --------------------------------------------------
    project          2048          4          4     00 [--none--]

    xfs_quota: print quota id number if the name can't be found

    When use GETNEXTQUOTA ioctl to report project quota, it always
    report an unexpected quota:

      (null) 0 0 0 00 [--------]

    The ID 0 store the default quota, even if no one set default quota,
    it still have quota accounting, but not enforced. So GETNEXTQUOTA
    can find and report this undefined quota.

    From this problem, I thought if others' quota name miss, (null) will
    be printed too. e.g.

      # xfs_quota -xc "limit -u bsoft=300m bhard=400m test" $mnt
      # xfs_quota -xc "report -u" $mnt
      User ID          Used       Soft       Hard    Warn/Grace
      ---------- --------------------------------------------------
      root                0          0          0     00 [--------]
      test                0     307200     409600     00 [--------]
      # userdel -r test
      # xfs_quota -xc "report -u" $mnt
      User ID          Used       Soft       Hard    Warn/Grace
      ---------- --------------------------------------------------
      root                0          0          0     00 [--------]
      (null)              0     307200     409600     00 [--------]

    So this problem same with above id 0's problem. To deal with this,
    this patch will print id number if the name can't be found.

    However, if we use the old GETQUOTA ioctl, it won't print project id
    0 quota information if it's not defined. That's different with
    GETNEXTQUOTA. For keep consistent, this patch also print project id
    0 when use old GETQUOTA.

    xfs_quota: fully support users and groups beginning with digits

    A normal user or group name allow beginning with digits, but xfs_quota
    can't create a limit for that user or group. The reason is 'strtoul'
    function only translate digits at the beginning, it will ignore
    letters after digits.

    There's a commit fd537fc50eeade63bbd2a66105f39d04a011a7f5, it try to
    fix "xfsprogs: xfs_quota allow user or group names beginning with
    digits". But it doesn't effect 'limit' command, so a command likes:

      xfs_quota 'limit .... 12345678-user' xxxx

    will try to create limit for username="12345678", not "12345678-user".

    This patch will fix this problem, and a test case xfs/138 in xfstests
    is used to reproduce this bug.

    xfs: wire up Q_XGETNEXTQUOTA / get_nextdqblk

    Source kernel commit 296c24e26ee3af2dbfecb482e6bc9560bd34c455

    Add code to allow the Q_XGETNEXTQUOTA quotactl to quickly find
    all active quotas by examining the quota inode, and skipping
    over unallocated or uninitialized regions.

    Userspace can then use this interface rather than i.e. a
    getpwent() loop when asked to report all active quotas.
