* lib/blkdev: remove support for Linux < 2.6Ruediger Meier2017-06-291-11/+2Star
| | | | | | Remove a hack for kernels between 2.4.15 and 2.4.17 Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* lib: use unique ifdefs for testsKarel Zak2017-01-041-1/+1
| | | | | | | Let's use unique TEST_PROGRAM_<NAME> ifdefs to make build system more robust. Signed-off-by: Karel Zak <kzak@redhat.com>
* blkdev: guard against missing DIOCGDINFO on FreeBSD 11Franco Fichtner2016-08-111-2/+2
| | | | | DIOCGMEDIASIZE is supported and available since FreeBSD 5, it may make sense to kill the backwards-glue completely instead.

* lib/blkdev: add open_blkdev_or_file() functionSami Kerola2015-11-221-0/+24
| | | | | | | | | Purpose of this function is to open a path that is potentially pointing to a block device or file without races. The function also proper open(3) flags are used to check the device is not busy, and finally warning is been printed if a block device happens to be misaligned.

* loopdev: sync capacity after setting itJeff Mahoney2013-04-091-2/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I recently tried to mount an hfsplus file system from an image file with a partition table by using the loop offset and sizelimit options to specify the location of the file system. hfsplus stores some metadata at a set offset from the end of the partition, so it's sensitive to the device size reported by the kernel. It worked with this: But failed with this: /dev/loop0: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /dev/loop1: [0089]:2 (<imagefile>), offset 32768, sizelimit 102400000 /proc/partitions shows the correct number of blocks to match the sizelimit. But if I set a breakpoint in mount before the mount syscall, I could see: 102400000 102432768 The kernel loop driver will set the gendisk capacity of the device at LOOP_SET_STATUS64 but won't sync it to the block device until one of two conditions are met: All open file descriptors referring to the device are closed (and it will sync when re-opened) or if the LOOP_SET_CAPACITY ioctl is called to sync it. Since mount opens the device and passes it directly to the mount syscall after LOOP_SET_STATUS64 without closing and reopening it, the sizelimit argument is effectively ignroed. The capacity needs to be synced immediately for it to work as expected. This patch adds the LOOP_SET_CAPACITY call to loopctx_setup_device since the device isn't yet released to the user, so it's safe to sync the capacity immediately.

* libblkid: use BLKSSZGET for GPT sectorsKarel Zak2009-10-221-1/+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>
