partitions/msdos: Unable to mount UFS 44bsd partitions

2018-04-08T09:51:56+00:00

commit 5f15684bd5e5ef39d4337988864fec8012471dda upstream. UFS partitions from newer versions of FreeBSD 10 and 11 use relative addressing for their subpartitions. But older versions of FreeBSD still use absolute addressing just like OpenBSD and NetBSD. Instead of simply testing for a FreeBSD partition, the code needs to also test if the starting offset of the C subpartition is zero. https://bugzilla.kernel.org/show_bug.cgi?id=197733 Signed-off-by: Richard Narron Signed-off-by: Jens Axboe Signed-off-by: Greg Kroah-Hartman

partitions/msdos: FreeBSD UFS2 file systems are not recognized

2017-06-17T04:39:34+00:00

commit 223220356d5ebc05ead9a8d697abb0c0a906fc81 upstream. The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD and NetBSD partitions and does a reasonable job picking out OpenBSD and NetBSD UFS subpartitions. But for FreeBSD the subpartitions are always "bad". Kernel: Reviewed-by: Christoph Hellwig Signed-off-by: Jens Axboe Signed-off-by: Greg Kroah-Hartman

partitions/msdos: enumerate also AIX LVM partitions

2013-07-09T17:33:28+00:00

Graft AIX partitions enumeration into partitions/msdos.c There is already a AIX disks detection logic in msdos.c. When an AIX disk has been found, and if configured to, call the aix partitions recognizer. This avoids removal of AIX disks protection from msdos.c, avoids code duplication, and ensures that AIX partitions enumeration is called before plain msdos partitions enumeration.

block/partition/msdos: detect AIX formatted disks even without 55aa

2013-02-28T03:10:21+00:00

AIX formatted disks do not always have the MSDOS 55aa signature. This happens e.g. for unbootable AIX disks. Up to now, such disks were not recognized as AIX disks, because of the missing 55aa. Fix that by inverting the two tests. Let's first check for the AIX magic strings, and only if that fails check for the MSDOS magic word.

block: partition: msdos: provide UUIDs for partitions

2012-11-23T13:28:58+00:00

The MSDOS/MBR partition table includes a 32-bit unique ID, often referred to as the NT disk signature. When combined with a partition number within the table, this can form a unique ID similar in concept to EFI/GPT's partition UUID. Constructing and recording this value in struct partition_meta_info allows MSDOS partitions to be referred to on the kernel command-line using the following syntax: root=PARTUUID=0002dd75-01 Signed-off-by: Stephen Warren Cc: Tejun Heo Cc: Will Drewry Cc: Kay Sievers Signed-off-by: Andrew Morton Signed-off-by: Jens Axboe
