* build-sys: don't connect _DEPENDENCIES and _LIBADDKarel Zak2014-03-051-1/+2
| | | | | | | | | The _DEPENDENCIES has to be used for dependencies on another in-tree files, but _LIBADD is to specify additional libs (including external libs). Reported-by: oleid <notifications@github.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* umount: don't use mountinfo if possibleKarel Zak2014-03-035-31/+242
| | | | | | | | | | | | | | | | | | | | | | | | The umount(8) always parses /proc/self/mountinfo to get fstype and to merge kernel mount options with userspace mount options from /run/mount/utab. This behavior is overkill in many cases and it's pretty expensive as kernel has to always compose *whole* mountinfo. This performance disadvantage is visible for crazy use-cases with huge number of mountpoints and frequently called umount(8). It seems that we can bypass /proc/self/mountinfo by statfs() to get filesystem type (statfs.f_type magic) and analyze /run/mount/utab before we parse mountinfo. This optimization is not used when: * umount(8) executed by non-root (as user= in utab is expected) * umount --lazy / --force (target is probably unreachable NFS, then use statfs() is pretty bad idea) * target is not a directory (e.g. umount /dev/sda1) * there is (deprecated) writeable mtab Reported-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Karel Zak <kzak@redhat.com>

| | | | | | | | | | It seems that linux 3.14 is able to produce things like: 19 0 8:3 / / rw,relatime - ext4 /dev/sda3 rw,data=ordered ^ Reported-by: Mantas Mikulėnas <grawity@gmail.com> Signed-off-by: Karel Zak <kzak@redhat.com>
* libmount: initialize *root to NULL in mnt_table_get_root_fsThomas Bächler2014-02-171-0/+2
| | | | | | | | mnt_table_get_root_fs only works when *root is set to NULL. This is not only undocumented, but also unintuitive. Fix it by initializing *root inside mnt_table_get_root_fs. Signed-off-by: Karel Zak <kzak@redhat.com>

* include/c.h: prefer nanosleep() over usleep()Karel Zak2014-01-241-2/+2
| | | | | | | | | | | | | | Let's use nanosleep() although if usleep() exists. The nanosleep function does no interact with signals and other timers. The patch introduces xusleep() as replacement to libc (or our fallback) usleep(). Yes, we don't want to use struct timespec + nanosleep() everywhere in code as nano-time resolution is useless for us. The patch also enlarges delays in some busy wait loops. It seems enough to try read/write 4x per second. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: update utab after successful extern helper mountKarel Zak2013-11-043-10/+84
| | | | | | | | | | | | | | | This patch allows to maintain private utab libmount file also for external mount/umount helpers that are not linked with libmount. The libmount check if utab has been updated after successful extern helper execution (status=0). If not then the file is updated. This patch affects only 'user' fstab mount option. So, for example with suid mount.cifs you can use: //server/foo /mnt cifs username=foo,noauto,user Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: compose mount.<type> helpers paths more carefullyKarel Zak2013-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | The [u]mount helper path is "/sbin/mount.<type>", the <type> should not be possible to interpret like a path, for example: # mkdir /sbin/mount.fake # mount -t fake/../../../home/user/foo.sh Anyway, this is *not mount(8) security issue*, because: - non-root users don't have permissions to specify -t on mount(8) command line - /sbin is not writable for regular users This patch makes libmount more robust for situations when the library is used by incompetent developers who don't sanitize user's input.
