* libblkid: support pseudo PARTUUID= for MBRKarel Zak2013-06-133-1/+14
| | | | | | | | | | | | # blkid /dev/sdb1 dev/sdb1: TYPE="ext2" PARTUUID="54e743a7-01" the PARTUUID is generated from MBR Id and partition number. The same method uses Linux kernel for root=PARTUUID= on systems with MBR. Note that the patch also removes 0x prefix from PTUUID. Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: use correct block size for UDF probeZachary Catlin2013-03-021-15/+30
| | | | | | | | | | | In UDF, Volume Structure Descriptors are always 2048 bytes long (ECMA-167, 3rd ed., §2/9.1), while filesystem sectors are the same size as the sectors of the underlying media (e.g., UDF 2.01 §1.3.2). Before this commit, the block size was estimated from VSD offsets, which gives incorrect answers for non-optical media. Now, the UDF probe uses the device block size by default, falling back to 2048-byte sectors for the case of optical-disk images. Signed-off-by: Zachary Catlin <z@zc.is>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have seen blkid failing to report any meaningful data on some of UDF volumes I have (Windows installer media): $ ./blkid -p -o udev en_windows_7_professional_with_sp1_x64_dvd_u_676939.iso ID_FS_LABEL=UDF_Volume ID_FS_LABEL_ENC=UDF\x20Volume ID_FS_TYPE=udf Also, once my patches to expose more of ISO9660 info get merged, we'd also need the same info to be exposed for UDF volumes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to kill libosinfo's infamous udev rule[1], we need to make blkid report the following information as udev properties on IS09660 media so that libosinfo can make use of that for detection: 1. Volume ID (already exposed as label). 2. System ID. 3. Publisher ID. 4. Application ID. 5. Boot record's boot system ID, (almost always 'EL TORITO SPECIFICATION' if boot record is present).

* libblkid: make blkid_new_probe_from_filename() usable on whole-diskKarel Zak2013-02-061-0/+2
| | | | | | | | | | | | | | | | | This is stupid bug, when libblkid probe for partition table on whole-disk device with old 0.90 Linux RAID then it creates clone of the struct blkid_probe to avoid collisions with the original probing setting. If the cloned prober is unnecessary then it's deallocated by blkid_free_probe() ... and this function also closes the file descriptor if the device has been opened by blkid_new_probe_from_filename(). Fortunately we usually use open() + blkid_probe_set_device(), ... except wipefs(1). Reported-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: add blkid_probe_step_back()Karel Zak2013-02-043-22/+97
| | | | | | | | | | | | | | | | | | | | | | It seems that blkid_do_probe() is too high-level solution for some mkfs programs (for example ext4 mkfs supports "undo" so all write operations has to be implemented by filesystem specific functions). The new function blkid_probe_step_back() resets internal libblkid buffers and move probing stuff one step back. It means that the previously used probing function will be called again in the next blkid_do_probe() call. This allows to modify on-disk data and check for backup superblocks or alternative magic strings. Something like: while (blkid_do_probe(pr) == 0) { ... get SBMAGIC_OFFSET and SBMAGIC len ... ... use your private seek & write() ... blkid_probe_step_back(pr); } References: https://bugzilla.redhat.com/show_bug.cgi?id=902512 Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | Now libblkid (the cache based part) tries to probe for the cached filesystem firstly. This optimization is broken, because: * new another superblock could be on the device and the original is already obsolete * we still need to probe for partitions and raids * the code was too fragile The patch also suggests lsblk --fs in blkid.8 for end users. lsblk read information from used db.
