2011-03-05omfs: merge unlink() and rmdir(), close leak in rename()Al Viro1-40/+13
In case of directory-overwriting rename(), omfs forgot to mark the victim doomed, so omfs_evict_inode() didn't free it. We could fix that by calling omfs_rmdir() for directory victims instead of doing omfs_unlink(), but it's easier to merge omfs_unlink() and omfs_rmdir() instead. Note that we have no hardlinks here. It also makes the checks in omfs_rename() go away - they fold into what omfs_remove() does when it runs into a directory.

2011-03-05omfs: stop playing silly buggers with omfs_unlink() in ->rename()Al Viro1-4/+3
Since omfs directories are hashes of inodes and name is part of inode, we have to remove inode from old directory before we can put it into new one / under new name. So instead of bump i_nlink call omfs_unlink, which does omfs_delete_entry() decrement i_nlink and mark parent dirty in case of success decrement i_nlink if omfs_unlink failed and hadn't done it itself let's just call omfs_delete_entry() and dirty the parent ourselves...

2010-08-09remove inode_setattrChristoph Hellwig1-1/+11
Replace inode_setattr with opencoded variants of it in all callers. This moves the remaining call to vmtruncate into the filesystem methods where it can be replaced with the proper truncate sequence. In a few cases it was obvious that we would never end up calling vmtruncate so it was left out in the opencoded variant: spufs: explicitly checks for ATTR_SIZE earlier btrfs,hugetlbfs,logfs,dlmfs: explicitly clears ATTR_SIZE earlier ufs: contains an opencoded simple_seattr + truncate that sets the filesize just above In addition to that ncpfs called inode_setattr with handcrafted iattrs, which allowed to trim down the opencoded variant.

2010-05-27rename the generic fsync implementationsChristoph Hellwig1-1/+1
We don't name our generic fsync implementations very well currently. The no-op implementation for in-memory filesystems currently is called simple_sync_file which doesn't make too much sense to start with, the the generic one for simple filesystems is called simple_fsync which can lead to some confusion. This patch renames the generic file fsync method to generic_file_fsync to match the other generic_file_* routines it is supposed to be used with, and the no-op implementation to noop_fsync to make it obvious what to expect. In addition add some documentation for both methods. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo1-0/+1
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

2008-08-15omfs: fix potential oops when directory size is corruptedBob Copeland1-2/+1
Testing with a modified fsfuzzer reveals a couple of locations in omfs where filesystem variables are ultimately used as loop counters with insufficient sanity checking. In this case, dir->i_size is used to compute the number of buckets in the directory hash. If too large, readdir will overrun a buffer. Since it's an invariant that dir->i_size is equal to the sysblock size, and we already sanity check that, just use that value instead. This fixes the following oops: BUG: unable to handle kernel paging request at c978e004 IP: [<c032298e>] omfs_readdir+0x18e/0x32f Oops: 0000 [#1] PREEMPT DEBUG_PAGEALLOC Modules linked in: Pid: 4796, comm: ls Not tainted (2.6.27-rc2 #12) EIP: 0060:[<c032298e>] EFLAGS: 00010287 CPU: 0 EIP is at omfs_readdir+0x18e/0x32f EAX: c978d000 EBX: 00000000 ECX: cbfcfaf8 EDX: cb2cf100 ESI: 00001000 EDI: 00000800 EBP: cb2d3f68 ESP: cb2d3f0c DS: 007b ES: 007b FS: 0000 GS: 0033 SS: 0068 Process ls (pid: 4796, ti=cb2d3000 task=cb175f40 task.ti=cb2d3000) Stack: 00000002 00000000 00000000 c018a820 cb2d3f94 cb2cf100 cbfb0000 ffffff10 cbfb3b80 cbfcfaf8 000001c9 00000a09 00000000 00000000 00000000 cbfcfbc8 c9697000 cbfb3b80 22222222 00001000 c08e6cd0 cb2cf100 cbfb3b80 cb2d3f88 Call Trace: [<c018a820>] ? filldir64+0x0/0xcd [<c018a9f2>] ? vfs_readdir+0x56/0x82 [<c018a820>] ? filldir64+0x0/0xcd [<c018aa7c>] ? sys_getdents64+0x5e/0xa0 [<c01038bd>] ? sysenter_do_call+0x12/0x31 ======================= Code: 00 89 f0 89 f3 0f ac f8 14 81 e3 ff ff 0f 00 48 8d 14 c5 b8 01 00 00 89 45 cc 89 55 f0 e9 8c 01 00 00 8b 4d c8 8b 75 f0 8b 41 18 <8b> 54 30 04 8b 04 30 31 f6 89 5d dc 89 d1 8b 55 b8 0f c8 0f c9 Reported-by: Eric Sesterhenn <snakebyte@gmx.de> Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2008-07-26omfs: add directory routinesBob Copeland1-0/+504
Add lookup and directory management routines for OMFS. The filesystem uses hashing based on the filename and stores collisions, unordered, in siblings of files' inode structures. To support telldir, the current position in the hash table is encoded in fpos.
