* partx: document -d vs. --nr and fix testHEADmasterKarel Zak2019-08-212-3/+11
| | | | | | | | | | The commit ab025087f91b66ee8e23a16bc49eb0d9bd421d65 has disabled error message, but unfortunately it keeps wrong return code. This has been fixed by commit 53ae7d60cfeacd4e87bfe6fcc015b58b78ef4555. This commit add hit about it to docs and fix regression test too. Signed-off-by: Karel Zak <kzak@redhat.com>
* partx: don't report ENXIO as error on -dKarel Zak2019-08-211-2/+1Star
| | | | | | | | | | | | | | | | | The errno ENXIO should be ignored, unfortunately the current code uses variable 'rc' for ioctl return code as well as for final del_parts() return value. So, failed ioctl (which should be ignored) affects all del_parts() status. # modprobe scsi_debug dev_size_mb=100 # partx -d --nr 1-1024 /dev/sdc; echo $? 1 The device dos not contains any partitions, so 0 return code is expected in this case.

* libmount: fix comment referring to passno fieldPatrick Steinhardt2019-08-201-1/+1
| | | | | | | | | | | There's an obvious copy-paste error in `mnt_parse_table_line` when referring to the 6th field of the fstab format, where it says "freq" instead of "passno". This has probably been copied from the 5th field, which is in fact correctly labelled as "freq". Fix the mistake by changing the comment to say "passno" instead.

| | | | | | | | | | | | | | | | | | | | | | | The "umount -f -a -r" get stuck in a endless loop when run with a mountinfo like below: 15 0 179:2 / / ro,relatime - ext4 /dev/root ro 16 15 0:6 / /dev rw,relatime - devtmpfs devtmpfs rw,size=242896k,nr_inodes=60724,mode=755 17 15 0:4 / /proc rw,relatime - proc proc rw 18 15 0:15 / /mnt/.psplash rw,relatime - tmpfs tmpfs rw,size=40k 19 15 0:16 / /sys rw,relatime - sysfs sysfs rw 20 19 0:7 / /sys/kernel/debug rw,relatime - debugfs debugfs rw 21 15 0:17 / /run rw,nosuid,nodev - tmpfs tmpfs rw,mode=755 22 15 0:18 / /var/volatile rw,relatime - tmpfs tmpfs rw 23 15 179:1 / /boot rw,relatime - vfat /dev/mmcblk0p1 rw,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 24 16 0:19 / /dev/pts rw,relatime - devpts devpts rw,gid=5,mode=620,ptmxmode=000 25 18 0:20 / /mnt/.psplash rw,relatime - tmpfs tmpfs rw,size=40k The reason is that the two same mnt entry "/mnt/.psplash" will cause the dst->tab set to NULL when umount this mnt entry the second time. This will trigger an endless loop in mnt_reset_table() because that mnt entry is linked on the libmnt_table but its .tab is set to NULL. Signed-off-by: Kevin Hao <kexin.hao@windriver.com>

| | | | | | | | | | | | | | | | | | | | The unnamed-field format supports partition type shortcuts: ",1MiB,L' but for named-field format it requires full type: (mbr) "size=1MiB,type=83" (gpt) "size=1MiB,type=0FC63DAF-8483-4772-8E79-3D69D8477DE4" This patch implements type shortcuts also for named-field format: "size=1MiB,type=L" to make it more user-friendly and unified.

* libblkid: fix file descriptor leak in blkid_verify()Karel Zak2019-07-312-4/+19
| | | | | | | | | | | | | | The function blkid_verify() uses private device file descriptor and uses blkid_probe_set_device() to assign the descriptor to low-level probing code. Unfortunately, close() in this case is not enough as the prober can internally open whole-disk device too. The library API has been extended so blkid_probe_set_device() deallocates and close previously used prober for whole-disk. This new functionality is used in blkid_verify() now.
