2011-08-11ext3: Properly count journal credits for long symlinksEric Sandeen
Commit ae54870a1dc9 ("ext3: Fix lock inversion in ext3_symlink()") recalculated the number of credits needed for a long symlink, in the process of splitting it into two transactions. However, the first credit calculation under-counted because if selinux is enabled, credits are needed to create the selinux xattr as well. Overrunning the reservation will result in an OOPS in journal_dirty_metadata() due to this assert: J_ASSERT_JH(jh, handle->h_buffer_credits > 0); Fix this by increasing the reservation size.

2011-07-25vfs: move ACL cache lookup into generic codeLinus Torvalds
This moves logic for checking the cached ACL values from low-level filesystems into generic code. The end result is a streamlined ACL check that doesn't need to load the inode->i_op->check_acl pointer at all for the common cached case. The filesystems also don't need to check for a non-blocking RCU walk case in their acl_check() functions, because that is all handled at a VFS layer.

2011-07-23ext3: Fix data corruption in inodes with journalled dataJan Kara
When journalling data for an inode (either because it is a symlink or because the filesystem is mounted in data=journal mode), ext3_evict_inode() can discard unwritten data by calling truncate_inode_pages(). This is because we don't mark the buffer / page dirty when journalling data but only add the buffer to the running transaction and thus mm does not know there are still unwritten data. Fix the problem by carefully tracking transaction containing inode's data, committing this transaction, and writing uncheckpointed buffers when inode should be reaped.

2011-07-20fs: push i_mutex and filemap_write_and_wait down into ->fsync() handlersJosef Bacik
Btrfs needs to be able to control how filemap_write_and_wait_range() is called in fsync to make it less of a painful operation, so push down taking i_mutex and the calling of filemap_write_and_wait() down into the ->fsync() handlers. Some file systems can drop taking the i_mutex altogether it seems, like ext3 and ocfs2. For correctness sake I just pushed everything down in all cases to make sure that we keep the current behavior the same for everybody, and then each individual fs maintainer can make up their mind about what to do from there.

2011-07-20fs: simplify the blockdev_direct_IO prototypeChristoph Hellwig
Simple filesystems always pass inode->i_sb_bdev as the block device argument, and never need a end_io handler. Let's simply things for them and for my grepping activity by dropping these arguments. The only thing not falling into that scheme is ext4, which passes and end_io handler without needing special flags (yet), but given how messy the direct I/O code there is use of __blockdev_direct_IO in one instead of two out of three cases isn't going to make a large difference anyway.

2011-07-18security: new security_inode_init_security API adds function callbackMimi Zohar
This patch changes the security_inode_init_security API by adding a filesystem specific callback to write security extended attributes. This change is in preparation for supporting the initialization of multiple LSM xattrs and the EVM xattr. Initially the callback function walks an array of xattrs, writing each xattr separately, but could be optimized to write multiple xattrs at once. For existing security_inode_init_security() calls, which have not yet been converted to use the new callback function, such as those in reiserfs and ocfs2, this patch defines security_old_inode_init_security().

2011-06-25ext3: Improve truncate error handlingJan Kara
New truncate calling convention allows us to handle errors from ext3_block_truncate_page(). So reorganize the code so that ext3_block_truncate_page() is called before we change inode size. This also removes unnecessary block zeroing from error recovery after failed buffered writes (zeroing isn't needed because we could have never written non-zero data to disk). We have to be careful and keep zeroing in direct IO write error recovery because there we might have already overwritten end of the last file block. Signed-off-by: Jan Kara <jack@suse.cz>
2011-06-25ext3: Fix oops in ext3_try_to_allocate_with_rsv()Jan Kara
Block allocation is called from two places: ext3_get_blocks_handle() and ext3_xattr_block_set(). These two callers are not necessarily synchronized because xattr code holds only xattr_sem and i_mutex, and ext3_get_blocks_handle() may hold only truncate_mutex when called from writepage() path. Block reservation code does not expect two concurrent allocations to happen to the same inode and thus assertions can be triggered or reservation structure corruption can occur. Fix the problem by taking truncate_mutex in xattr code to serialize allocations.

Mostly trivial conversion. We fix a bug that IS_IMMUTABLE and IS_APPEND files could not be truncated during failed writes as we change the code.

2011-06-25ext3: Add fixed tracepointsLukas Czerner
This commit adds fixed tracepoints to the ext3 code.

Tell the filesystem if we just updated timestamp (I_DIRTY_SYNC) or anything else, so that the filesystem can track internally if it needs to push out a transaction for fdatasync or not. This is just the prototype change with no user for it yet. I plan to push large XFS changes for the next merge window, and getting this trivial infrastructure in this window would help a lot to avoid tree interdependencies. Also remove incorrect comments that ->dirty_inode can't block. That has been changed a long time ago, and many implementations rely on it.

When make_indexed_dir() fails (e.g. because of ENOSPC) after it has allocated block for index tree root, we did not properly mark all changed buffers dirty.

2011-04-29ext3: Fix lock inversion in ext3_symlink()Jan Kara
ext3_symlink() cannot call __page_symlink() with transaction open. __page_symlink() calls ext3_write_begin() which gets page lock which ranks above transaction start (thus lock ordering is violated) and and also ext3_write_begin() waits for a transaction commit when we run out of space which never happens if we hold transaction open. Fix the problem by stopping a transaction before calling __page_symlink() (we have to be careful and put inode to orphan list so that it gets deleted in case of crash) and starting another one after __page_symlink() returns for addition of symlink into a directory.
