* losetup: try to set up loop readonly if EACCESMatthias Koenig2008-11-181-1/+2
| | | | | | | | | | | | | Currently mounting/losetup an image fails if it is accessable readonly. There are no problems if it is a file on a local filesystem. It seems only to happen if it is a NFS mounted image, which is read-write in permission but with root_squash option. set_loop checks only for EROFS to retry open with readonly mode, but in this case we get EACCES.

* mount: mtab created multiple times with -a optionKarel Zak2008-10-011-2/+5
| | | | | | | | | | | | | | When /etc/mtab does not exist and mount is called with -a, for every mount point that is mounted a root-fs record is added to mtab. This is because get_mtab_info() sets the flag mtab_does_not_exist to 1 when it doesn't find /etc/mtab. However, if it actually finds /etc/mtab, the variable is not reset to 0. So on every subsequent call to get_mtab_info() (as it is the case when mounting several mount points with the -a option), mount will think that /etc/mtab does not exist, even if it was created in the meantime by mount itself.

* losetup: remove dependence on minor numbersKarel Zak2008-08-211-0/+4
| | | | | | | | | | | The latest kernel supports partitioned loop devices (kernel commit 476a4813cfddf7cf159956cc0e2d3c830c1507e3). Unfortunately, this change makes minor numbers useless, because mirror number does not match with loop device name (loop<N>). We have to follow loop device names only.

* losetup: looplist_* refactoring, remove scandir()Karel Zak2008-08-041-149/+153
| | | | | | | | | | | | | | | | | | | | | | | | | This patch replaces scandir-based implementation with readdir(). The readdir(3) is less expensive and more portable (to non-glibc environment). The patch also replaces sysfs-based solution with simpler /proc/partitions parsing. The /proc/partitions includes all used loop devices on all systems (include 2.4). This solution seems faster than scandir(/sys/block/) too. Summary, the losetup (with this patch) uses three methods to found a loop device: a) parse /proc/partitions to found already used loop devices (for loserup -a) b) stat(2) for all loop[0-7] devices (default number of loop devices). This is classic method from util-linux <= 2.13. This method is good enough for standard Linux machines with default number of loop devices. c) scan all /dev or /dev/loop/ for loop devices. This is useful for crazy people who need more than 8 loop devices. Signed-off-by: Karel Zak <kzak@redhat.com>
* mount: retry on ENOMEDIUMMatthias Koenig2008-07-302-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to a change in kernel behaviour when opening CDROM devices, we need to retry the open/mount call when ENOMEDIUM is returned. Explanation from Tejun Heo: Okay, the difference is from the addition of cdrom_get_media_event() call to both sr_drive_status() and ide_cdrom_drive_status(). Previously, the cdrom driver can't differentiate between tray closed w/ no media and tray open and always returned tray open, which triggers close and retry in the open logic which probably have delayed things enough to get the media recognized. Now the cdrom driver can discern between tray closed w/o media and device not ready for other reasons and returns -ENOMEDIUM on the former. This is all good and dandy but the problem seems that some drives report no media right after the tray is closed but it hasn't properly detected the media yet. It seems the only way to work around the problem is via sensible retries (e.g. try three times 5 secs apart) and I don't think we can add that type of retry logic into cdrom open path. Please note that the previous logic wasn't water proof. Some drives can take longer to recognize the media is there and could have failed the in-kernel retry too. Also, reading the media can take quite some time and during that period the drive reports media present but device not ready. The driver will retry the command (e.g. READ TOC for open) five times but all of them can fail w/ EMEDIUMTYPE.

* umount: improve "-d" option for autoclear loopsKarel Zak2008-07-023-2/+34
| | | | | | | | | | | The new loop auto-destruct feature detaches automatically loop devices when no longer used. This means they are detached with the umount() call. But when we call umount with -d, del_loop() is called and fails because the ioctl() returns ENXIO. We have to check for autoclear loop devices rather than blindly call del_loop().

| | | | | | | | | | | | | | | | | | | | | The command # mount -oremount <spec> <dir> doesn't read fstab or mtab. This is expected behaviour.

* mount: "can't create lock file" message sometimes means failure, sometimes notMark McLoughlin2008-02-143-7/+15
| | | | | | | | | | | | | | | | | | | | What the patch does is goes from the situation where: 1) If /etc/mtab doesn't exist and /etc is read-only, you get the "can't create lock file" message and the mount fails 2) If /etc/mtab does exist and /etc is read-only,you get the same message but the mount succeeds Clearly, the failure to update /etc/mtab should either cause the mount to fail or not ... sometimes causing it to fail, and sometimes not (each with the same message) is not useful. This patch sets the same behaviour for create and update mtab. In both cases it prints error message and the mount succeeds.
