* lib/loopdev: set blocksize when create a new deviceKarel Zak2019-01-222-0/+25
| | | | | | | | | | | The partition scanner in kernel depends on blocksize. We need to set the blocksize before we call LOOP_SET_STATUS64 (this ioctl triggers the scanner). This patch extends the internal API to save blocksize into loopdev context to be usable later for loopcxt_setup_device(). Signed-off-by: Karel Zak <kzak@redhat.com>
* lib/loopdev: differentiate between setter()s and ioctl callsKarel Zak2019-01-223-13/+14
| | | | | | | | Now the internal API uses loopcxt_set_...() to set context variables as well as to call ioctls. This patch introduces loopcxt_ioctl_...() to makes things more obvious to readers. Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | | | | | | | | | Earlier gettimeofday() was affected by discontinuous jumps. Measuring how long time it takes to set time using function that effected by the very thing being measured makes head spin.

| | | | | | | | ENV_SUPATH and ENV_ROOTPATH are equivalent and ENV_ROOTPATH takes precedence in both login and su. It makes no sense. More logical would be precedence of ENV_SUPATH in su and ENV_ROOTPATH in login. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

| | | | | | | | | | | | | | | | su(1) documentation says: /etc/default/su command specific logindef config file /etc/login.defs global logindef config file It indirectly indicates that /etc/default/su should take precedence over /etc/login.defs. But the reverse is true. It is not possible to define ENV_PATH in /etc/login.defs and then make su specific customization in /etc/default/su. We need to change read order to match the documented behavior. Signed-off-by: Stanislav Brabec <sbrabec@suse.cz>

* libblkid: improve whole-disk detection when read /proc/partitionsKarel Zak2019-01-082-12/+15
| | | | | | | | | | | | | | | | | | 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.
