* libblkid: add support for PART_ENTRY_* valuesKarel Zak2010-02-183-7/+131
| | | | | | | | | | | | blkid(8) will be replacement for devkit-disks-part-id, so we have to be able to found entry in partition table for requested partition. This functionality is enabled by BLKID_PARTS_ENTRY_DETAILS flag (see blkid_probe_set_partitions_flags() for more details). This patch also add a new public function blkid_partlist_devno_to_partition(). Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: fix ZSF detectionAndreas Dilger2010-02-172-9/+19
| | | | | | | | | | | | | | | Fix the ZFS device detection by looking at multiple uberblocks to see if any are present, rather than looking for the ZFS boot block which is not always present. There may be up to 128 uberblocks, but the first 4 are not written to disk on a newly-formatted filesystem so check several of them at different offsets within the uberblock array.

| | | | | | | | | | It would be nice to minimize dependence between the disk layout and disk topology. We have to follow disk topology for alignment_offset and huge (> 1MiB) I/O sizes only. For all others disks we can use 1MiB grain and 1MiB offset. Reported-by: "H. Peter Anvin" <hpa@zytor.com> Signed-off-by: Karel Zak <kzak@redhat.com>

The code: int wfd = (int)(intptr_t) nl_langinfo(_NL_TIME_WEEK_1STDAY); does not work on big-endian machines. The original solution based on union is better.

| | | | | | | | | | | | | | | | | | | | | | | * don't print: The number of cylinders for this disk is set to 12161. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) we really don't care about MS-DOS or extremely old LILO. * inform users that DOS-compatible mode is bad and deprecated thing (It's difficult to use 2048 sectors grain or 4KiB sectors or alignment_offset in DOS mode where all is based on cylinders...) * don't check for cylinders boundary in non-DOS mode * inform about sector and I/O sizes Signed-off-by: Karel Zak <kzak@redhat.com>
* fdisk: fix default first sectorKarel Zak2010-02-091-5/+4Star
| | | | | | | | The previous release 2.17 introduces aligned defaults for the first and last sectors on the partition. Unfortunately, there is endless loop when the code looks for first unused aligned sector. Signed-off-by: Karel Zak <kzak@redhat.com>
* fdisk: cleanup alignment, default to 1MiB offsetKarel Zak2010-02-091-21/+66
| | | | | | | | | | | | | | | | | | | | * add heuristic to detect that the device does not provide topology information. We can use topology if: - alignment_offset is not 0 - or optimal_io_size is not 0 - or minimal_io_size is not power of 2 * default to 1MiB offset for the start of the first partition if topology is unknown. This (2048 512-byte sectors) is Windows Vista default. * use optimal_io_size, minimal_io_size or 1MiB as a grain for partitions alignment Note that this all is used when DOS-compatible mode is disabled.

* fdisk: don't check alignment_offset against geometryKarel Zak2010-02-091-12/+3Star
| | | | | | | | | | The alignment_offset is compensation for DOS compatible partitioning. It usually matches with disk geometry (e.g. 63 sectors), but the offset is also exported from phy.disks to RAIDs there the geometry don't match with the offset. So.. don't print unnecessary warning.

* libblkid: don't return error on empty filesKarel Zak2010-02-043-5/+10
| | | | | | | | | | | | | | Currently, the library does not allow to initialize blkid_probe if the file (or block device) is empty. The empty file is reported as an error. That's wrong. The empty file should be interpreted as a file without any FS or PT. It means that blkid_do_{probe,safeprobe,fullprobe}() have to return 1 ("nothing").

| | | | | | | | | | | | | | | | From 9262c9832134f8a33ac2ea2854dc6d20acc712d1 Mon Sep 17 00:00:00 2001 From: Adrian Knoth <adi@drcomp.erfurt.thur.de> Date: Tue, 2 Feb 2010 16:57:23 +0100 Subject: [PATCH] Add support for SCHED_RESET_ON_FORK to chrt SCHED_RESET_ON_FORK has been added in 2.6.31. If a thread has this flag set, chrt reports "unknown" policy, which is confusing. The patch adds support for this new flag. It will (can) only be applied to SCHED_FIFO or SCHED_RR, so there's no need to catch the other scheduling policies. Signed-off-by: Adrian Knoth <adi@drcomp.erfurt.thur.de>
* libblkid: minor fixes in befs.cKarel Zak2010-02-021-8/+16
| | | | | | | | | The library does not reset the probing result (e.g. LABEL, VERSION) when the probing function failed (return value != 0). We have to be absolutely sure that the FS has been properly detected before we set LABEL or VERSION or so. Signed-off-by: Karel Zak <kzak@redhat.com>

* libblkid: add blkid_probe_all_removable()Karel Zak2010-02-016-8/+116
| | | | | | | | | | | | | | The libblkid probing is based on devices from /proc/partitions by default. This file usually does not contain removable devices (e.g. CDROMs) and this kind of devices are invisible for libblkid. The blkid_probe_all_removable() function adds removable block devices to blkid cache. The probing is based on information from the /sys directory. The devices which were detected by this function won't be written to blkid.tab cache file. Addresses: https://bugzilla.redhat.com/show_bug.cgi?id=533874 Signed-off-by: Karel Zak <kzak@redhat.com>
