2013-11-23block: Abstract out bvec iteratorKent Overstreet1-1/+1
Immutable biovecs are going to require an explicit iterator. To implement immutable bvecs, a later patch is going to add a bi_bvec_done member to this struct; for now, this patch effectively just renames things.

2012-06-17hfsplus: fix overflow in sector calculations in hfsplus_submit_bioJanne Kalliomäki1-1/+1
The variable io_size was unsigned int, which caused the wrong sector number to be calculated after aligning it. This then caused mount to fail with big volumes, as backup volume header information was searched from a wrong sector.

Commit 6596528e391a ("hfsplus: ensure bio requests are not smaller than the hardware sectors") changed the pointers used for volume header allocations but failed to free the correct pointers in the error path path of hfsplus_fill_super() and hfsplus_read_wrapper. The second hunk came from a separate patch by Pavel Ivanov.

2011-07-22hfsplus: ensure bio requests are not smaller than the hardware sectorsSeth Forshee1-20/+63
Currently all bio requests are 512 bytes, which may fail for media whose physical sector size is larger than this. Ensure these requests are not smaller than the block device logical block size.

2011-06-30hfsplus: lift the 2TB size limitChristoph Hellwig1-4/+0
Replace the hardcoded 2TB limit with a dynamic limit based on the block size now that we have fixed the few overflows preventing operation with large volumes. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2011-06-30hfsplus: fix overflow in hfsplus_read_wrapperChristoph Hellwig1-2/+3
For partitions larger than 2TB or at such an offset the hfs wrapper code in hfsplus might overflow the range representable in a 32-bit data type. Make sure we use a sector_t for the arithmetics leading to it. I'm not sure this code can be readed at all as hfs itself never supported such large volumes.

2010-11-23hfsplus: use raw bio access for the volume headersChristoph Hellwig1-59/+104
The hfsplus backup volume header is located two blocks from the end of the device. In case of device sizes that are not 4k aligned this means we can't access it using buffer_heads when using the default 4k block size. Switch to using raw bios to read/write all buffer headers. We were not relying on any caching behaviour of the buffer heads anyway. Additionally always read in the backup volume header during mount to verify that we can actually read it.

2010-10-01hfsplus: use atomic bitops for the superblock flagsChristoph Hellwig1-5/+9
The flags in the HFS+-specific superlock do get modified during runtime, use atomic bitops to make the modifications SMP safe. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2010-10-01hfsplus: fix HFSPLUS_SB calling conventionChristoph Hellwig1-15/+15
HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock information like all other FOO_SB macros, but dereference the pointer in a way that made it look like a direct struct derefence. This only works as long as the HFSPLUS_SB macro is used directly and prevents us from keepig a local hfsplus_sb_info pointer. Fix the calling convention and introduce a local sbi variable in all functions that use it constantly. Signed-off-by: Christoph Hellwig <hch@tuxera.com>
2009-10-29hfsplus: refuse to mount volumes larger than 2TBBen Hutchings1-0/+4
As found in <http://bugs.debian.org/550010>, hfsplus is using type u32 rather than sector_t for some sector number calculations. In particular, hfsplus_get_block() does: u32 ablock, dblock, mask; ... map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask)); I am not confident that I can find and fix all cases where a sector number may be truncated. For now, avoid data loss by refusing to mount HFS+ volumes with more than 2^32 sectors (2TB).

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering1-1/+0
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+171
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
