* libblkid: remove dependence on libuuidKarel Zak2019-01-224-23/+1Star
| | | | | | | | | | | Currently we use libuuid to print UUID only. This code is possible to replace by one snprintf(). It seems better to duplicate this one snprintf than force all distros to keep libuuid together with libblkid. Note, this scenario has been already supported on --disable-libuuid.

* libblkid: improve whole-disk detection when read /proc/partitionsKarel Zak2019-01-081-11/+14
| | | | | | | | | | | | | | | | | | blkid(8) in high-level mode checks partitions and unpartitioned whole-disk devices from the file /proc/partitions. The current heuristic assumes that partition name ends with a digit. Unfortunately, this is not correct -- for example md0 or nvme0n1 are whole-disk devices. This commit uses sysfs_devno_is_wholedisk() to make sure the device is a partition (according to kernel or DM). It's probably more expensive, because this way requires more syscalls (to read stuff from /sys etc.). The patch also adds more information to the blkid(8) man page.

| | | | | | | | | | | This patch adds search for a secondary LUKS2 header, if the primary one is corrupted. This patch is primarily needed for wipefs that should wipe both signatures (otherwise LUKS2 header recovery can use secondary header and revert wipefs action).

| | | | | | | | | | | | | | | | | | | | | | | | | | According to the UDF 2.60 specification, the Minimum UDF Read Revision value shall be at most #0250 for all media with a UDF 2.60 file system. So in this case use Minimum UDF Write Revision as ID_FS_VERSION to distinguish between UDF 2.50 and UDF 2.60 discs. This commit also adds a testing Blu-Ray Recordable image with UDF revision 2.60 created by Nero which really sets Minimum UDF Read Revision to 2.50. Signed-off-by: Pali Rohár <pali.rohar@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Use only label from the root directory and do not fallback to the label stored in boot sector. This is how MS-DOS 6.22, MS-DOS 7.10, Windows 98, Windows XP and also Windows 10 behave. Moreover Windows XP and Windows 10 do not touch label in boot sector anymore, so removing FAT label on those Windowses leads to having old label still stored in boot sector (which MS-DOS and Windows fully ignore). * Label entry "NO NAME" in root directory is treated as label "NO NAME" instead of empty label. In root directory it has no special meaning. String "NO NAME" has a special meaning (empty label) only for label stored in boot sector. * Label from the boot sector is now stored into LABEL_FATBOOT field. So if there are applications which depends or needs to read this label, they have ability. After this change LABEL always correspondent to the label from the root directory and LABEL_FATBOOT to the label stored in the boot sector. If some of those labels is missing or is not present (e.g. "NO LABEL" in boot sector) then particular field is not set. Signed-off-by: Pali Rohár <pali.rohar@gmail.com>
