2009-09-17ext4: Fix the alloc on close after a truncate hueristicTheodore Ts'o
In an attempt to avoid doing an unneeded flush after opening a (previously non-existent) file with O_CREAT|O_TRUNC, the code only triggered the hueristic if ei->disksize was non-zero. Turns out that the VFS doesn't call ->truncate() if the file doesn't exist, and ei->disksize is always zero even if the file previously existed. So remove the test, since it isn't necessary and in fact disabled the hueristic. Thanks to Clemens Eisserer that he was seeing problems with files written using kwrite and eclipse after sudden crashes caused by a buggy Intel video driver.

2009-09-17ext4: store EXT4_EXT_MIGRATE in i_state instead of i_flagsTheodore Ts'o
EXT4_EXT_MIGRATE is only intended to be used for an in-memory flag, and the hex value assigned to it collides with FS_DIRECTIO_FL (which is also stored in i_flags). There's no reason for the EXT4_EXT_MIGRATE bit to be stored in i_flags, so we switch it to use i_state instead.

2009-09-16ext4: limit block allocations for indirect-block files to < 2^32Eric Sandeen
Today, the ext4 allocator will happily allocate blocks past 2^32 for indirect-block files, which results in the block numbers getting truncated, and corruption ensues. This patch limits such allocations to < 2^32, and adds BUG_ONs if we do get blocks larger than that. This should address RH Bug 519471, ext4 bitmap allocator must limit blocks to < 2^32 * ext4_find_goal() is modified to choose a goal < UINT_MAX, so that our starting point is in an acceptable range. * ext4_xattr_block_set() is modified such that the goal block is < UINT_MAX, as above. * ext4_mb_regular_allocator() is modified so that the group search does not continue into groups which are too high * ext4_mb_use_preallocated() has a check that we don't use preallocated space which is too far out * ext4_alloc_blocks() and ext4_xattr_block_set() add some BUG_ONs No attempt has been made to limit inode locations to < 2^32, so we may wind up with blocks far from their inodes. Doing this much already will lead to some odd ENOSPC issues when the "lower 32" gets full, and further restricting inodes could make that even weirder. For high inodes, choosing a goal of the original, % UINT_MAX, may be a bit odd, but then we're in an odd situation anyway, and I don't know of a better heuristic.

2009-09-16ext4: Fix different block exchange issue in EXT4_IOC_MOVE_EXTAkira Fujita
If logical block offset of original file which is passed to EXT4_IOC_MOVE_EXT is different from donor file's, a calculation error occurs in ext4_calc_swap_extents(), therefore wrong block is exchanged between original file and donor file. As a result, we hit ext4_error() in check_block_validity(). To detect the logical offset difference in EXT4_IOC_MOVE_EXT, add checks to mext_calc_swap_extents() and handle it as error, since data exchange must be done between the same blocks in EXT4_IOC_MOVE_EXT.

2009-09-16ext4: Add null extent check to ext_get_pathAkira Fujita
There is the possibility that path structure which is taken by ext4_ext_find_extent() indicates null extents. Because during data block exchanging in ext4_move_extents(), constitution of an extent tree may be changed. As a solution, the patch adds null extent check to ext_get_path().

2009-09-16ext3: Flush disk caches on fsync when neededJan Kara
In case we fsync() a file and inode is not dirty, we don't force a transaction to disk and hence don't flush disk caches. Thus file data could be just in disk caches and not on persistent storage. Fix the problem by flushing disk caches if we didn't force a transaction commit. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-16ext3: Add locking to ext3_do_update_inodeChris Mason
I've been struggling with this off and on while I've been testing the data=guarded work. The symptom is corrupted orphan lists and inodes with the wrong i_size stored on disk. I was convinced the data=guarded code was just missing a call to ext3_mark_inode_dirty, but tracing showed the i_disksize I was sending to ext3_mark_inode_dirty wasn't actually making it to the drive. ext3_mark_inode_dirty can be called without locks held (atime updates and a few others), so the data=guarded code uses locks while updating the in-memory inode, and then calls ext3_mark_inode_dirty without any locks held. But, ext3_mark_inode_dirty has no internal locking to make sure that only one CPU is updating the buffer head at a time. Generally this works out ok because everyone that changes the inode then calls ext3_mark_inode_dirty themselves. Even though it races, eventually someone updates the buffer heads and things move on. But there is still a risk of the wrong values getting in, and the data=guarded code seems to hit the race very often. Since everyone that changes the inode also logs it, it should be possible to fix this with some memory barriers. I'll leave that as an exercise to the reader and lock the buffer head instead. It it probably a good idea to have a different patch series for lockless bit flipping on the ext3 i_state field. ext3_do_update_inode &= clears EXT3_STATE_NEW without any locks held.

2009-09-16ext3: Fix possible deadlock between ext3_truncate() and ext3_get_blocks()Jan Kara
During truncate we are sometimes forced to start a new transaction as the amount of blocks to be journaled is both quite large and hard to predict. So far we restarted a transaction while holding truncate_mutex and that violates lock ordering because truncate_mutex ranks below transaction start (and it can lead to a real deadlock with ext3_get_blocks() allocating new blocks from ext3_writepage()). Luckily, the problem is easy to fix: We just drop the truncate_mutex before restarting the transaction and acquire it afterwards. We are safe to do this as by the time ext3_truncate() is called, all the page cache for the truncated part of the file is dropped and so writepage() cannot come and allocate new blocks in the part of the file we are truncating. The rest of writers is stopped by us holding i_mutex. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-16jbd: Annotate transaction start also for journal_restart()Jan Kara

2009-09-16jbd: Journal block numbers can ever be only 32-bit use unsigned int for themJan Kara

2009-09-16writeback: fix possible bdi writeback refcounting problemNick Piggin
wb_clear_pending AFAIKS should not be called after the item has been put on the list, except by the worker threads. It could lead to the situation where the refcount is decremented below 0 and cause lots of problems.

2009-09-16writeback: separate starting of sync vs opportunistic writebackJens Axboe
bdi_start_writeback() is currently split into two paths, one for WB_SYNC_NONE and one for WB_SYNC_ALL. Add bdi_sync_writeback() for WB_SYNC_ALL writeback and let bdi_start_writeback() handle only WB_SYNC_NONE. Push down the writeback_control allocation and only accept the parameters that make sense for each function. This cleans up the API considerably. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
