* blkid: don't read past end of FAT32 cluster chainJohn Lindgren2011-05-121-1/+3
| | | | | | | | | | | | | | | | | | | | | | | When looking for a volume label on a FAT32 filesystem, blkid does not correctly handle special cluster values in the range 0x0FFFFFF8 to 0x0FFFFFFF, which mark the last cluster in a chain. As a result, it begins to read [what it treats as] FAT entries from past the end of the FAT. Depending on the data read, it may then try to parse random data from the filesystem (including user files, free space, and other directories) as though it were part of the root directory. Because parsing stops early when a volume label is found, the problem only occurs on filesystems without a volume label. When it occurs, it may result in a long sequence of lseek and read calls; on an older IDE drive with a 2 GB FAT32 partition, this amounted to around 3 seconds of disk I/O. After patching, blkid stop parsing as soon as it reaches a cluster value greater than or equal to the number of entries in the FAT.

* libmount: add support for x-* mount commentsKarel Zak2011-04-212-3/+14
| | | | | | | | | | | | | | | | | | | | | | | 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.

* libblkid: remove test for non-zero head count in FAT superblock probe.Nick Holloway2011-04-121-2/+0Star
| | | | | | | | | | | | | | 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>

* libmount: fix parsing of mountinfo from 2.6.39Karel Zak2011-04-051-8/+21
| | | | | | | | | | The /proc/self/mountinfo file uses " - " field as a separator between optional fields and next fields in the file. The '-' char could be used in the fields (for example in UUIDs), so it's necessary to check for whole " - " string rather than for '-' char only. Reported-by: "Aneesh Kumar K.
