2010-03-15mount: report ambivalent FS detection, improve brute force detectionKarel Zak1-9/+24
The ambivalent probing result should be properly reported and user should be informed that the problem is possible to bypass by "-t <type>" or resolved by wipefs(8). The mount(8) command uses a brute force stage (calls mount(2) for all /{proc,etc}/fylesystems) if there is not any other way how to detect the filesystem type. The brute force stage should not be restricted by libblkid. It's possible that libblkid is not able to detect slightly corrupted filesystem, but kernel is able to mount such filesystem. Note that the brute force stage should not be used if libblkid returns ambivalent probing result. In this case user's intervention is required (e.g. mount -t <type>).

Note, this typo does not have any impact on the utils in the util-linux-ng project, because we don't use MD5 for any security sensitive data or cryptographic stuff. The typo also does not have any impact to the final MD5 hashes. Reported-by: Jochen Voss <voss@seehuhn.de> Signed-off-by: Karel Zak <kzak@redhat.com>

2009-10-26mount: and libblkid: covert /dev/dm-N to /dev/mapper/<name>Karel Zak1-4/+44
* mount(8) uses private device-mapper names in mtab * libblkid returns private device-mapper names when evaluate udev /dev/disk-by symlinks. * on systems where DM is fully integrated with udev the /dev/mapper/<name> files are symlinks to /dev/dm-N. It means we need a special care to hide private device-mapper names. Signed-off-by: Karel Zak <kzak@redhat.com>
2009-10-22libblkid: use BLKSSZGET for GPT sectorsKarel Zak1-1/+5
The current implementation uses fixed sector size (512 bytes), that's wrong. UEFI standard requires real logical sector size -- it means BLKSSZGET for Linux. The size of GPT header is not static, but whole sector is allocated for the header. In theory the HeaderSize field could be greater than sizeof(struct gpt_header). It means we have to read whole sector with the header, because the header crc32 checksum is counted according to HeaderSize. Signed-off-by: Karel Zak <kzak@redhat.com>

2009-09-16lib: add a generic crc32()Karel Zak1-0/+116
This is public domain implementation, based on static crc32_table[]. This implementation is used on may places (libparted, FreeBSD kernel, PostgreSQL, ...). The Linux kernel uses on-the-fly generated and allocated tables. That's useless in shared libraries. Signed-off-by: Karel Zak <kzak@redhat.com>

2009-04-29blkid: rename blkid_evaluate_spec to blkid_evaluate_tagKarel Zak1-7/+7
"SPEC" is usually used in mount(8) as a generic term for device name or tag (LABEL, UUID). The function blkid_evaluate_* works with TAGs only. Signed-off-by: Karel Zak <kzak@redhat.com>
