* libmount: improve fs referencing in tablesTim Hildering2019-03-081-0/+1
| | | | | | | | | | | | | | | * Added member 'struct libmnt_table *tab' to libmnt_fs structure. * Added 'mnt_fs_get_table()'. * Removed overhead from 'mnt_table_{insert,move,remove}_fs(). * Added check to 'mnt_table_set_iter()' that entry is member of table. [kzak@redhat.com: - add to libmount.sys - add to docs - cleanup commit message - set fs->tab = NULL before mnt_unref_fs() in mnt_table_remove_fs()] Signed-off-by: Tim Hildering <hilderingt@posteo.net> Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: add mnt_context_get_excode()Karel Zak2017-04-271-3/+13
| | | | | | | | | | | | | | | | It's pretty complex task to make mount(8) and umount(8) return code and generate error message. It seems better to do that in the libmount rather than force all library users to duplicate mount(8) mk_exit_code() functions. It also means that all the messages will be translated only once. Changes: * all error messages are printed by warn() * no more multi-line messages * all messages prefixed by mount target (mountpoint) * library provides mount(8) compatible MNT_EX_* codes Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=1429531 Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: support MS_RDONLY on write-protected devicesKarel Zak2017-04-261-0/+3
| | | | | | | | This feature is supported by mount(8) only. It seems better move this code to libmount. The results is more simple mount(8) and the feature is accessible for all libmount users. Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: reimplement mnt_match_options()Karel Zak2016-12-201-1/+1
| | | | | | | | Let's use optstr.c functions to parse pattern and options strings. It's more robust that the old original mount(8) code and it supports quotes in the options strings. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: handle btrfs default subvolume mountStanislav Brabec2016-01-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When mounting btrfs volume without subvol= and subvolid=, and the btrfs volume has default subvolume defined, mount() mounts the default subvolume and not the volume root as other filesystems do. To handle this situation correctly (for example for "mount -a"), libmount has to be capable to detect default subvolume. Add btrfs.c and btrfs.h that implement needed functions. This patch adds mnt_table_find_target_with_option() to the library API. Known problems not covered by this patch: - Use of subvolid= in fstab is not yet handled. - Use of type auto in combination with subvol= in fstab is not yet handled. - Use of btrfs in loop devices, where image file is specified in fstab is not yet handled (use of /dev/loop0 in fstab works). - If fstab uses subvol=, and subvol path changes since last "mount -a", subsequent "mount -a" will not recognize that it is already mounted, and it will attempt to mount it second time. To fix it, libmount should remember subvolid in time of mount (subvolid is unique for the subvolume, subvol is not). - mountinfo contains subvol and subvolid since kernel 4.2. Before kernel 4.2, there is no reasonable way to solve this situation. (One would create temporary mount point, mount the default, call needed ioctl() to determine what was mounted, deduce the default subvolume, compare it with subvolume of mounted volume, unmount and return result.) How to reproduce: truncate -s1G btrfs_test.img mkdir -p btrfs_mnt /sbin/mkfs.btrfs -f -d single -m single ./btrfs_test.img mount -o loop btrfs_test.img btrfs_mnt pushd . cd btrfs_mnt mkdir -p d0/dd0/ddd0 cd d0/dd0/ddd0 touch file{1..5} btrfs subvol create s1 cd s1 touch file{1..5} mkdir -p d1/dd1/ddd1 cd d1/dd1/ddd1 btrfs subvol create s2 rid=$(btrfs inspect rootid s2) echo new default $rid btrfs subvol get-default . btrfs subvol set-default $rid . popd umount btrfs_mnt losetup /dev/loop0 $PWD/btrfs_test.img echo "/dev/loop0 $PWD/btrfs_mnt btrfs defaults 0 0" >>/etc/fstab mount -a mount -a umount btrfs_mnt sed -i "/\/dev\/loop0/d" /etc/fstab losetup -d /dev/loop0 rm btrfs_test.img rmdir btrfs_mnt Current behavior: mount: /dev/loop0 is already mounted or /root/btrfs_mnt busy /dev/loop0 is already mounted on /root/btrfs_mnt Expected behavior is to ignore already mounted FS.

* libmount: add new libmnt_monitor APIKarel Zak2014-12-052-0/+13
| | | | | | | | | | | | It's usually enough to us [e]poll() to monitor kernel mount table, but there is no way how to monitor changes in userspace mount options (e.g. _netdev). The management of these mount options is completely hidden in libmount and /rub/mount/utab is private libmount file. This patch introduces new libmnt_mount API to monitor also userspace mount table.
