* libmount: close device fd (to avoid mount(2) EBUSY)Karel Zak2012-04-271-53/+17Star
| | | | | | | | | | | | libmount uses libblkid to detect filesystem type. Unfortunately, the blkid probe struct is not freed before mount(2), it means that the device is still open and mount(2) may return EBUSY. We don't need persistent blkid stuff in libmount, so let's close all immediately after device probing. Reported-by: David Zeuthen <zeuthen@gmail.com> Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: fix mount by patternKarel Zak2012-04-241-1/+4
| | | | | | | | | | | mount /foo /bar without entry in /etc/fstab the mount command tries all filesystems from /{etc,proc}/filesystems. We should NOT call mount(2) more then once if the syscall returns for example ENOENT, acceptable is only EINVAL. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: fix "already mounted" detection on systems with mtabKarel Zak2012-03-091-17/+49

* libmount: avoid infinite loop in child fs iterationDave Reisner2012-03-081-0/+5
| | | | | | | | | | | | | | | | | | In early userspace, the rootfs is mounted with itself as its parent. Example /proc/self/mountinfo: 1 1 0:1 / / rw - rootfs rootfs rw 14 1 0:3 / /proc rw,nosuid,nodev,noexec,relatime - proc proc rw 15 1 0:13 / /sys rw,nosuid,nodev,noexec,relatime - sysfs sys rw 16 1 0:5 / /dev rw,nosuid,relatime - devtmpfs dev rw,size=506956k 17 1 0:14 / /run rw,nosuid,nodev,relatime - tmpfs run rw,mode=755 This causes an infinite loop in mnt_table_next_child_fs, and is evidenced by a crash via infinite recursion in findmnt. Simply catch the condition where the ID of the parent is the ID of the current fs we're examining and skip over it to the next mount in the table. Signed-off-by: Dave Reisner <dreisner@archlinux.org>

* libmount: add mnt_fs_streq_srcpath()Karel Zak2012-03-024-32/+35
| | | | | | | | | | We have to be careful with "none" or another dummy sources for pseudo filesystems. These strings should be canonicalized or compared as a paths. The function is not exported by library API. Signed-off-by: Karel Zak <kzak@redhat.com>

* libmount: don't treat "none" differentlyDave Reisner2012-03-023-15/+6Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This causes more problems than it solves. In the latest edition: # mount -t proc none foo mount: foo: mount failed: Invalid argument A check for source and target fails in mnt_context_apply_fstab() because, even though they were indeed specified on the cmdline, __mnt_fs_set_source_ptr() altered this and NULL'd out the source. If you're able to mount this device via other means, other tools start reporting oddities, such as mount's output: (null) on /foo type proc (rw,relatime) or findmnt: TARGET SOURCE FSTYPE OPTIONS /foo proc rw,relatime Simply treat "none" like any other source when passed in.

* libmount: use mount.<type> -s for NFS onlyKarel Zak2012-02-271-1/+6

* mount: distinguish between MS_COMMENT flags (netdev, nofail, ...)Karel Zak2012-02-231-0/+4
| | | | | | | | | | Since util-linux 2.12h (year 2004) there is only one flag for all dummy options like _netdev or nofail. Unfortunately it means that when mount(8) composes the final mount options string for mtab (or for mount.<type> helpers) the string is generated incorrectly.

* libmount: remove teaser proto for mnt_table_get_nameDave Reisner2012-02-223-3/+0Star
| | | | | | | | | | This function was never implemented, but the proto has existed since the inception of the library. As the libmnt_table struct doesn't include a member necessary to carry the name of the table, simply discard this prototype. If ever a need to break ABI comes up, perhaps this could be revisited.
