2015-02-10	fsioctl.c: make generic_block_fiemap() signal-tolerant	Dmitry Monakhov	1	-1/+2
	__generic_block_fiemap may spin very long time for large sparse files. Without this patch an unprivileged user may abuse system resources simply by spawning a vast number of unkilable busyloops (works on ext2/ext3): truncate --size 1T test for ((i=0;i<1024;i++)) do filefrag test > /dev/null & done Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Cc: Theodore Ts'o <tytso@mit.edu> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Michael Kerrisk <mtk.manpages@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-10-08	vfs: vfs-level fiemap interface	Mark Fasheh	1	-0/+228
	Basic vfs-level fiemap infrastructure, which sets up a new ->fiemap inode operation. Userspace can get extent information on a file via fiemap ioctl. As input, the fiemap ioctl takes a struct fiemap which includes an array of struct fiemap_extent (fm_extents). Size of the extent array is passed as fm_extent_count and number of extents returned will be written into fm_mapped_extents. Offset and length fields on the fiemap structure (fm_start, fm_length) describe a logical range which will be searched for extents. All extents returned will at least partially contain this range. The actual extent offsets and ranges returned will be unmodified from their offset and range on-disk. The fiemap ioctl returns '0' on success. On error, -1 is returned and errno is set. If errno is equal to EBADR, then fm_flags will contain those flags which were passed in which the kernel did not understand. On all other errors, the contents of fm_extents is undefined. As fiemap evolved, there have been many authors of the vfs patch.
