* Only move shared libraries to /lib if they existsThomas Petazzoni2014-06-161-1/+1
| | | | | | | | | | | | | | | | | | In several Makemodule.am, there is a install-exec-hook-<library> target whose role is to move the shared library from /usr/lib to /lib, while keeping a symbolic link /usr/lib/libuuid.so -> ../../lib/<library>.so.<version>. However, when util-linux is built with --enable-static --disable-shared (as is needed on noMMU platforms that don't support shared libraries), no <library>.so is built, but the install-exec-hook-libuuid creates an invalid /usr/lib/<library>.so symbolic link, pointing to ../../lib (yes, the directory). This causes troubles later one when other libraries/programs are compiled with -l<library>, as gcc thinks a shared library is available because there's a file named /usr/lib/<library>.so.

* libblkid: ignore private LVM devicesKarel Zak2014-06-106-3/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The virtual private LVM devices do not contain any blkid relevant data and it does not make any sense to scan for superblocks or partitions on the devices, because we can interpret data from the devices in bad way. Unfortunately, for LVM has "private" very special meaning. The private LVM devices are accessible and readable (according to LVM guys it's feature, because debugging etc.). The problem is pretty visible with LVM thin provisioning where a virtual pool device contains segments from the top-level thin devices. Mountable top-level LVM-thin device: # blkid -o udev -p /dev/mapper/vg-thin1 ID_FS_UUID=57ed6490-903b-416c-91d2-6d06804ec60c ID_FS_TYPE=ext4 Virtual private LVM-pool device (contains data from all thin devices): # blkid -o udev -p /dev/mapper/vg-pool0 ID_FS_UUID=57ed6490-903b-416c-91d2-6d06804ec60c ID_FS_TYPE=ext4 ... this is incorrect, vg-pool0 is unmountable. LVM uses special UUID suffixes for private devices. All devices with uuid in format "LVM-<uuid>-<type>" are private. This patch modifies libblkid to not scan such devices. The high-level API ignores such devices at all now. The low-level API allows to assign the device to blkid_prober, but all scan functions always return nothing and library does not read anything from the device. The another functionality (get parental device, topology, sector sizes, etc.) still works as expected. The change affects only probing code.

* | libblkid: detect squashfs 3 vs 4Ruediger Meier2014-05-263-15/+50
|/ | | | | | | | | | | | | | | | | | | | | | Detect squashfs version <= 3 as squashfs3 and version >= 4 as squashfs. squashfs kernel module version 4.0 (kernel 2.6.29) is not backward compatible to open squashfs created with previous versions. Also fixed version number parsing, see $ mkdir test $ mksquashfs test test.sqsh $ blkid -p test.sqsh - test.sqsh: VERSION="1024.0" TYPE="squashfs" USAGE="filesystem" + test.sqsh: VERSION="4.0" TYPE="squashfs" USAGE="filesystem" This patch comes from openSUSE / SLE.

* libblkid: fix return codes from PART_ENTRY_* probingKarel Zak2014-04-151-1/+11
| | | | | | | | | | | | | | | | The partitions prober does two step: 1) probe the assigned device for partition table 2) probe whole-disk device for partition table if the assigned device is a partition (this generates PART_ENTRY_* results for blkid -p -o udev)) The step 2) is optional and the return code from this probing should not override success (rc=0) from the step 1) -- except situations when the step 2) ends with I/O error or when the step 1) found nothing, but 2) was successful.

* | blkid: convert superblocks to new calling conventionHannes Reinecke2014-03-2056-303/+376
| | | | | | | | | | | | | | | | | | | | | | | | | | With the previous patch the scanning functions were modified to return a differentiated return code. To correctly abort scanning when an I/O error occurs we need to differentiate between 'error' (= -1) and 'not found' (= 1) in the probe functions. This patch updates all superblock scanning functions to the new calling convention. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever we fail to read from a device it's pointless to continue with probing; we should be failing immediately. Otherwise the system will continue logging I/O errors. This patch updates the probe functions to return the negative error number on error and BLKID_PROBE_NONE if not found.

* libblkid: Identify extN file system properlyLukas Czerner2013-12-121-180/+3Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently when trying to identify extN file system we're playing games with searching for kernel modules and parsing /proc/filesystem. All of this just because ext4 module can be used to mount ext3 and ext2 file systems on recent kernel and also because of ext4dev. However all of this is not necessary. Ext4 module which does support mounting ext2 and ext3 file system is able to recognize and mount ext2 and ext3 type so there is no need to disguise it and ext4dev should only be ever used for testing and not as fallback when other modules are missing (use -t instead). This also introduces a bug when in situation that we only have ext4 modules with ext2/ext3 support which is not loaded and we try to mount ext2 file system we will mount it incorrectly as ext4. This will not happen if the ext4 module is already loaded. With this patch we remove all the unnecessary checks and return the real type of the file system which is on the device. This fixes the issue. However on the kernel which was not compiled with EXT4_USE_FOR_EXT23 support one would have to provide file system type (-t) to be able to mount the file system with ext4 driver.
