  • 0607fd025   fat: detect media without partition table correctly ... Browse Code »

    I received a complaint that some FAT formated medias (e.g. sd memory cards)
    trigger a "unknown partition table" message even though there is no partition
    table and they work correctly, while in general (when e.g. formated with
    mkdosfs or even Windows Vista) this message is not shown.

    Currently this seems only to happen when the medias get formatted with Windows
    XP (and possibly Win 2000). Then the boot indicator byte contains garbage
    (part of text message) and so do the other parts checked by msdos_paritition
    which then later triggers this message.

    References: novell bug #364365

    Most fat formatted media without partition table contains zeros in the boot
    indication and the other tested bytes and so falls through the checks in
    msdos_partition, leading it to return with 1 (all is fine).

    But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so
    the check fails and causes a "unkown partition table" warning eventhough there
    is none and everything would be fine.

    This additional check directly verifies if there is a fat formatted medium
    without a partition table.

    Userspace likes to get notified that the disk may have changed, when
    rescan_partitions() is called after partitioning or media change. It will
    make it possible to update the state of the disk with the "change" event,
    before the following partition "add" events are handled.

  • 959bc220d   Fix LDM for new field in the VOL5 VBLK. ... Browse Code »

    Teach LDM about a new field encountered with Windows Vista.

    This fixes LDM for people using Vista who have disabled drive letter
    assignment from one or more volumes. Doing this introduces a so far
    unknown field in the LDM database in the VOL5 VBLK structure which
    causes the LDM driver to fail to parse the VBLK structure and hence LDM
    fails to parse the disk altogether. This patch teaches the driver about
    this field.

    Thanks got to Ashton Mills for reporting the
    problem and working with me on getting it fixed. It is now working for
    him.

  • 7b595756e   sysfs: kill unnecessary attribute->owner ... Browse Code »

    sysfs is now completely out of driver/module lifetime game. After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners. Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.

    This patch kills now unnecessary attribute->owner. Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.

    For more info regarding lifetime rule cleanup, please read the
    following message.

    ecryptfs, 1 in jffs2, and a possible cleared data overwritten with readpage in

    with a !uptodate page.

    So, with the current code, we end up returning -1 and not EIO for the
    ioctl() calls. Which doesn't give any clue to the user of what went
    wrong.

  • 4419d1ac7   [PATCH] relax check for AIX in msdos partition table ... Browse Code »

    The patch to identify AIX disks and ignore them has caused at least one
    machine to fail to find the root partition on 2.6.19. The patch is:

    http://lkml.org/lkml/2006/7/31/117

    The problem is some disk formatters do not blow away the first 4 bytes
    of the disk. If the disk we are installing to used to have AIX on it,
    then the first 4 bytes will still have IBMA in EBCDIC.

    The install in question was debian etch. Im not sure what the best fix
    is, perhaps the AIX detection code could check more than the first 4
    bytes.

    The whole partition info for primary partitions is in this block:

    dd if=/dev/sdb count=$(( 4 * 16 )) bs=1 skip=$(( 0x1be ))

    All other data do not matter, beside the 0x55aa marker at the end of the
    first block.

  • d18d7682c   [PARTITION]: Add whole_disk attribute. ... Browse Code »

    Some partitioning systems create special partitions that
    span the entire disk. One example are Sun partitions, and
    this whole-disk partition exists to tell the firmware the
    extent of the entire device so it can load the boot block
    and do other things.

    Such partitions should not be treated as normal partitions,
    because all the other partitions overlap this whole-disk one.
    So we'd see multiple instances of the same UUID etc. which
    we do not want. udev and friends can thus search for this
    'whole_disk' attribute and use it to decide to ignore the
    partition.
