* agetty.c: further scrubbingSami Kerola2011-04-271-545/+555
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | In reply to two requests. http://permalink.gmane.org/gmane.linux.utilities.util-linux-ng/3990 http://permalink.gmane.org/gmane.linux.utilities.util-linux-ng/3999 The scubbing consists; o Old school introduction back to the top of the source file. o Indentation changes. o Removal of void casting. o Removal of braces from single statements. o Unified format for comments. o Comparison with W. Venema's code from 1993 to clean few comment mysteries. o Web referrals added to further explanation to near the code or comments which some could find difficult to understand why. o Clean up of comments. o FIXME items added where attention is needed. o Make functions static. o Functions with same argument types use same argument order. o Get rid of classic K&R style function declarations. Please notice that this patch _should not_ affect how program works e.g. this has no actual code changes. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* libmount: add support for x-* mount commentsKarel Zak2011-04-215-7/+18
| | | | | | | | | | | | | | | | | | | | | | | The current way how add any comment or extra information to /etc/fstab is to use comment="" mount option. This is not too elegant and readable if you want to add more than one comment. It seems better to add any generic prefix that will be used for all 3rd-party userspace mount options. Expected syntax is: x-<application>-<options>[=<data>] For example: x-systemd-bar=managed All x-* options (as well as comment=) are ignored by libmount and not stored to the mtab file.

* mount: use fflush() and temporary file for mtab updates (CVE-2011-1089)Karel Zak2011-04-122-28/+29
| | | | | | | | | | | | | | | | | | http://thread.gmane.org/gmane.comp.security.oss.general/4374 Changes: - force mount(8) to use /etc/mtab.tmp file every time. The original code used the tmp file for remount/move operations only. - call and check fflush() return code for the tmp file Note mount(8) blocks all signals when writing to mtab, so it's not affected by SIGXFSZ and the mtab lock file is always removed. This patch does not fix the same issue in umount(8) and libmount. Signed-off-by: Karel Zak <kzak@redhat.com>
* libblkid: remove test for non-zero head count in FAT superblock probe.Nick Holloway2011-04-123-2/+8
| | | | | | | | | | | | | | This change enables the auto-detection of the internal storage on a VTech Kidizoom camera, which has a zero head count value in the superblock. Microsoft documentation, "FAT: General Overview of On-Disk Format", states that the sectors and heads fields are only relevant for media that have a geometry. The Linux kernel also does not require a non-zero head count, and can manually mount the filesystem. Signed-off-by: Nick Holloway <Nick.Holloway@pyrites.org.uk>
