2009-09-14udf: Fix possible corruption when close races with writeJan Kara1-0/+2
When we close a file, we remove preallocated blocks from it. But this truncation was not protected by i_mutex and thus it could have raced with a write through a different fd and cause crashes or even filesystem corruption. Signed-off-by: Jan Kara <jack@suse.cz>
2009-09-14udf: Perform preallocation only for regular filesJan Kara1-9/+10
So far we preallocated blocks also for directories but that brings a problem, when to get rid of preallocated blocks we don't need. So far we removed them in udf_clear_inode() which has a disadvantage that 1) blocks are unavailable long after writing to a directory finished and thus one can get out of space unnecessarily early 2) releasing blocks from udf_clear_inode is problematic because VFS does not expect us to redirty inode there and it also slows down memory reclaim. So preallocate blocks only for regular files where we can drop preallocation in udf_release_file. Signed-off-by: Jan Kara <jack@suse.cz>

2009-09-14fsync: wait for data writeout completion before calling ->fsyncChristoph Hellwig1-4/+1
Currenly vfs_fsync(_range) first calls filemap_fdatawrite to write out the data, the calls into ->fsync to write out the metadata and then finally calls filemap_fdatawait to wait for the data I/O to complete. What sounds like a clever micro-optimization actually is nast trap for many filesystems. For many modern filesystems i_size or other inode information is only updated on I/O completion and we need to wait for I/O to finish before we can write out the metadata. For old fashionen filesystems that instanciate blocks during the actual write and also update the metadata at that point it opens up a large window were we could expose uninitialized blocks after a crash. While a few filesystems that need it already wait for the I/O to finish inside their ->fsync methods it is rather suboptimal as it is done under the i_mutex and also always for the whole file instead of just a part as we could do for O_SYNC handling. Here is a small audit of all fsync instances in the tree: - spufs_mfc_fsync: - ps3flash_fsync: - vol_cdev_fsync: - printer_fsync: - fb_deferred_io_fsync: - bad_file_fsync: - simple_sync_file: don't care - filesystems/drivers do't use the page cache or are purely in-memory. - simple_fsync: - file_fsync: - affs_file_fsync: - fat_file_fsync: - jfs_fsync: - ubifs_fsync: - reiserfs_dir_fsync: - reiserfs_sync_file: never touch pagecache themselves. We need to wait before if we do not want to expose stale data after an allocation. - afs_fsync: - fuse_fsync_common: do the waiting writeback itself in awkward ways, would benefit from proper semantics - block_fsync: Does a filemap_write_and_wait on the block device inode. Because we now have f_mapping that is the same inode we call it on in vfs_fsync. So just removing it and letting the VFS do the work in one go would be an improvement. - btrfs_sync_file: - cifs_fsync: - xfs_file_fsync: need the wait first and currently do it themselves. would benefit from doing it outside i_mutex. - coda_fsync: - ecryptfs_fsync: - exofs_file_fsync: - shm_fsync: only passes the fsync through to the lower layer - ext3_sync_file: doesn't seem to care, comments are confusing. - ext4_sync_file: would need the wait to work correctly for delalloc mode with late i_size updates. Otherwise the ext3 comment applies. currently implemens it's own writeback and wait in an odd way, could benefit from doing it properly. - gfs2_fsync: not needed for journaled data mode, but probably harmless there. Currently writes back data asynchronously itself. Needs some major audit. - hostfs_fsync: just calls fsync/datasync on the host FD. Without the wait before data might not even be inflight yet if we're unlucky. - hpfs_file_fsync: - ncp_fsync: no-ops. Dangerous before and after. - jffs2_fsync: just calls jffs2_flush_wbuf_gc, not sure how this relates to data. - nfs_fsync_dir: just increments stats, claims all directory operations are synchronous - nfs_file_fsync: only writes out data??? Looks very odd. - nilfs_sync_file: looks like it expects all data done, but not sure from the code - ntfs_dir_fsync: - ntfs_file_fsync: appear to do their own data writeback. Very convoluted code. - ocfs2_sync_file: does it's own data writeback, but no wait. probably needs the wait. - smb_fsync: according to a comment expects all pages written already, probably needs the wait before. This patch only changes vfs_fsync_range, removal of the wait in the methods that have it is left to the filesystem maintainers. Note that most filesystems really do need an audit for their fsync methods given the gems found in this very brief audit.

Introduce also new helper for syncing after a sync write (generic_write_sync) using the generic function. Use these new helpers for syncing from generic VFS functions. This makes O_SYNC writes to block devices acquire i_mutex for syncing. If we really care about this, we can make block_fsync() drop the i_mutex and reacquire it before it returns.

generic_file_direct_write() and generic_file_buffered_write() called generic_osync_inode() if it was called on O_SYNC file or IS_SYNC inode. But this is superfluous since generic_file_aio_write() does the syncing as well. Also XFS and OCFS2 which call these functions directly handle syncing themselves. So let's have a single place where syncing happens: generic_file_aio_write(). We slightly change the behavior by syncing only the range of file to which the write happened for buffered writes but that should be all that is required.

2009-09-14fs/Kconfig: move nilfs2 outside misc filesystemsRyusuke Konishi2-2/+2
Some people asked me questions like the following: On Wed, 15 Jul 2009 13:11:21 +0200, Leon Woestenberg wrote: > just wondering, any reasons why NILFS2 is one of the miscellaneous > filesystems and, for example, btrfs, is not in Kconfig? Actually, nilfs is NOT a filesystem came from other operating systems, but a filesystem created purely for Linux. Nor is it a flash filesystem but that for generic block devices. So, this moves nilfs outside the misc category as I responded in LKML "Re: Why does NILFS2 hide under Miscellaneous filesystems?" (Message-Id: <20090716.002526.93465395.ryusuke@osrg.net>).

2009-09-14nilfs2: convert nilfs_bmap_lookup to an inline functionRyusuke Konishi3-36/+28
The nilfs_bmap_lookup() is now a wrapper function of nilfs_bmap_lookup_at_level(). This moves the nilfs_bmap_lookup() to a header file converting it to an inline function and gives an opportunity for optimization. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
2009-09-14nilfs2: allow btree code to directly call dat operationsRyusuke Konishi4-299/+167
The current btree code is written so that btree functions call dat operations via wrapper functions in bmap.c when they allocate, free, or modify virtual block addresses. This abstraction requires additional function calls and causes frequent call of nilfs_bmap_get_dat() function since it is used in the every wrapper function. This removes the wrapper functions and makes them available from btree.c and direct.c, which will increase the opportunity of compiler optimization.

2009-09-14nilfs2: add update functions of virtual block address to datRyusuke Konishi3-20/+44
This is a preparation for the successive cleanup ("nilfs2: allow btree to directly call dat operations"). This adds functions bundling a few operations to change an entry of virtual block address on the dat file. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
2009-09-14nilfs2: remove individual gfp constants for each metadata fileRyusuke Konishi8-19/+9
This gets rid of NILFS_CPFILE_GFP, NILFS_SUFILE_GFP, NILFS_DAT_GFP, and NILFS_IFILE_GFP. All of these constants refer to NILFS_MDT_GFP, and can be removed. Signed-off-by: Ryusuke Konishi <konishi.ryusuke@lab.ntt.co.jp>
