* Revert "include sysmacros.h where used"Karel Zak2016-03-081-1/+0Star

* include sysmacros.h where usedMike Frysinger2016-03-081-0/+1
| | | | | | | | BSD/Linux systems stick major/minor/makedev in sysmacros.h. Newer Linux libraries have been moving away from including sysmacros.h implicitly via sys/types.h, so include it directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* lib/sysfs: rename devname functions, cleanupKarel Zak2015-05-281-1/+0Star
| | | | | | | | | | | | | | | | | | Well, I don't have mental power to use function names like sysfs_devname_to_dev_name() so this patch renames to sysfs_devname_sys_to_dev() sysfs_devname_dev_to_sys() It also cleanups usage of the functions. We have to be sure that sysfs.c code returns regular devnames. The existence of the sysfs devnames (with '!') should be completely hidden in sysfs specific code.

* Fix /sys to /dev node name translationStanislav Brabec2015-05-261-0/+1
| | | | | | | | | | | | | | linux/drivers/base/core.c: device_get_devnode() defines a translation of '!' in sysfs nodes to '/' in /dev nodes. The same translation has to be done to properly support device nodes with slash (e. g. device nodes of cciss driver and several other drivers). Introduce new helper sysfs_devname_to_devno() and use it where appropriate. Fixes for example lsblk -f on devices using cciss driver. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* libblkid: ignore private LVM devicesKarel Zak2014-06-101-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
