2010-04-07libblkid: fix 'partno' usageKarel Zak6-10/+26
Linux kernel ignores empty partitions, but partition number is always allocated for the partition. (This rule is used for primary partitions only.) For example: part 1. size=12345 part 2. size=0 part 3. size=24567 the final list of partitions: sda1 sda3 'sda2' is not defined and partno=2 is not used for any other partitions. The libblkid library has to be compatible with this rule. Signed-off-by: Karel Zak <kzak@redhat.com>

2010-03-31libblkid: avoid probing CDs for RAIDM.S.Colclough4-0/+24
RAID probing of CD/DVD can yield errors because of well-known problem in reading the end of the disk with some disk/drive combinations. Borrow CD detection method from udev and skip the RAID tests for these devices.

2010-03-31blockdev: reduce usage text widthFrancesco Cosoleto1-4/+4
Use spaces in usage text instead of tabs and reduce the distance between option names and descriptions. This helps to minimize problems due to limited number of columns and translated texts which take up more space than English. Signed-off-by: Francesco Cosoleto <cosoleto@gmail.com>

2010-03-31build-sys: improved check for fallocate()Yann Droneaud1-1/+36
With glibc 2.10 on a 32bits system, fallocate64() function is not exported. This a problem, since _FILE_OFFSET_BITS is set to 64 and fallocate() is redirected to fallocate64(). Sadly, AC_CHECK_FUNC() doesn't catch such problem, since it's overriding the function prototype.

2010-03-19fdisk: fix -b <sectorsize>Karel Zak2-7/+15
The old fdisk (<2.17) does not differentiate between logical and physical sector size, it uses the <sectorsize> for everything. Now, we have logical and physical sectors size, but the -b option changes the logical size only. The second bug is that "fdisk -b <sz>" does not read topology information (it means that all I/O limits and physical sector size are 512 (default). The backwardly compatible bug fix is to override both sizes, logical and physical if "-b" is used. In future we can add a special option for physical size only.

2010-03-17libblkid: add microsecond resolution for cache entriesKarel Zak6-16/+51
The libblkid library uses stat.st_mtine to detect changes on the device. The last update time of of the device in the cache is stored as TIME= tag in the /etc/blkid.tab file. Linux since 2.5.48 supports nanosecond resolution and more precise time is available in the stat.st_mtim timespec struct. This patch add microsecond precision to TIME= tag in the cache file, old format: TIME="<sec>" the new format: TIME="<sec>.<usec>" This change is backwardly compatible. Now, the blkid_verify() function checks stat.st_mtime and stat.st_mtim.tv_nsec/1000.

2010-03-15mount: automatically detect and loop-mount regular filesKarel Zak2-11/+41
This patch allows to automatically create a loop device from a regular file if a filesystem type is not specified, for example: mount /path/disk.img /mnt If the filesystem type is specified than "-o loop" is required. Note that there is not a restriction (on kernel side) that prevents regular file as a mount(2) source argument. A filesystem that is able to mount regular files could be implemented. Based on a patch from Adam Jackson <ajax@redhat.com>. Signed-off-by: Karel Zak <kzak@redhat.com>

2010-03-15mount: report ambivalent FS detection, improve brute force detectionKarel Zak3-14/+34
The ambivalent probing result should be properly reported and user should be informed that the problem is possible to bypass by "-t <type>" or resolved by wipefs(8). The mount(8) command uses a brute force stage (calls mount(2) for all /{proc,etc}/fylesystems) if there is not any other way how to detect the filesystem type. The brute force stage should not be restricted by libblkid. It's possible that libblkid is not able to detect slightly corrupted filesystem, but kernel is able to mount such filesystem. Note that the brute force stage should not be used if libblkid returns ambivalent probing result. In this case user's intervention is required (e.g. mount -t <type>).

2010-03-11libblkid: improve ZFS detection and add LABEL and UUID extractionAndreas Dilger2-37/+183
Improve ZFS uberblock detection to loop over multiple uberblocks, and detect at least 4 magic values, to avoid random collisions. It doesn't yet probe the VDEV LABEL at the end of the device, though it wouldn't be too hard to add it at this point if needed. Add extraction of the pool name (as LABEL), the VDEV (block device) guid as UUID_SUB, and pool_guid (volume) as UUID from the nvlist in the VDEV LABEL. Do simple sanity checking on the nvlist data values to avoid overflowing the buffer if they are corrupt in any way.
