2007-05-08[XFS] Fix to prevent the notorious 'NULL files' problem after a crash.Lachlan McIlroy
The problem that has been addressed is that of synchronising updates of the file size with writes that extend a file. Without the fix the update of a file's size, as a result of a write beyond eof, is independent of when the cached data is flushed to disk. Often the file size update would be written to the filesystem log before the data is flushed to disk. When a system crashes between these two events and the filesystem log is replayed on mount the file's size will be set but since the contents never made it to disk the file is full of holes. If some of the cached data was flushed to disk then it may just be a section of the file at the end that has holes. There are existing fixes to help alleviate this problem, particularly in the case where a file has been truncated, that force cached data to be flushed to disk when the file is closed. If the system crashes while the file(s) are still open then this flushing will never occur. The fix that we have implemented is to introduce a second file size, called the in-memory file size, that represents the current file size as viewed by the user. The existing file size, called the on-disk file size, is the one that get's written to the filesystem log and we only update it when it is safe to do so. When we write to a file beyond eof we only update the in- memory file size in the write operation. Later when the I/O operation, that flushes the cached data to disk completes, an I/O completion routine will update the on-disk file size. The on-disk file size will be updated to the maximum offset of the I/O or to the value of the in-memory file size if the I/O includes eof.

2007-05-08[XFS] propogate return codes from flush routinesLachlan McIlroy
This patch handles error return values in fs_flush_pages and fs_flushinval_pages. It changes the prototype of fs_flushinval_pages so we can propogate the errors and handle them at higher layers. I also modified xfs_itruncate_start so that it could propogate the error further.

2007-02-10[XFS] Remove unused header files for MAC and CAP checking functionality.Eric Sandeen
xfs_mac.h and xfs_cap.h provide definitions and macros that aren't used anywhere in XFS at all. They are left-overs from "to be implement at some point in the future" functionality that Irix XFS has. If this functionality ever goes into Linux, it will be provided at a different layer, most likely through the security hooks in the kernel so we will never need this functionality in XFS.

2006-11-11[XFS] Prevent a deadlock when xfslogd unpins inodes.David Chinner
The previous fixes for the use after free in xfs_iunpin left a nasty log deadlock when xfslogd unpinned the inode and dropped the last reference to the inode. the ->clear_inode() method can issue transactions, and if the log was full, the transaction could push on the log and get stuck trying to push the inode it was currently unpinning. To fix this, we provide xfs_iunpin a guarantee that it will always have a valid xfs_inode <-> linux inode link or a particular flag will be set on the inode. We then use log forces during lookup to ensure transactions are completed before we recycle the inode. This ensures that xfs_iunpin will never use the linux inode after it is being freed, and any lookup on an inode on the reclaim list will wait until it is safe to attach a new linux inode to the xfs inode.

2006-09-28[XFS] Really fix use after free in xfs_iunpin.David Chinner
The previous attempts to fix the linux inode use-after-free in xfs_iunpin simply made the problem harder to hit. We actually need complete exclusion between xfs_reclaim and xfs_iunpin, as well as ensuring that the i_flags are consistent during both of these functions. Introduce a new spinlock for exclusion and the i_flags, and fix up xfs_iunpin to use igrab before marking the inode dirty.
