[2.6-GIT] NTFS: Release 2.1.23.
From: Anton Altaparmakov
Date: Thu Jul 14 2005 - 07:13:54 EST
Hi Linus, please pull from
rsync://rsync.kernel.org/pub/scm/linux/kernel/git/aia21/ntfs-2.6.git/HEAD
This is a big NTFS update. It was meant for as soon as 2.6.12 was released
but it was delayed due to the need for a patch I submitted to Andrew for -mm
to make it to the mainline kernel (which it has as of yesterday).
This update includes lots of fixes including a really nasty deadlock that with
recent kernels was triggered with 100% probability on umount of an NTFS volume
so it is important to go in before 2.6.13 is released.
Please apply. Thanks!
Best regards,
Anton

NTFS: Fix a nasty deadlock that appeared in recent kernels.
The situation: VFS inode X on a mounted ntfs volume is dirty. For
same inode X, the ntfs_inode is dirty and thus corresponding on-disk
inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
to the table of inodes, i.e. $MFT, inode 0.
What happens:
Process 1: sys_sync()/umount()/whatever... calls
__sync_single_inode() for $MFT -> do_writepages() -> write_page for
the dirty page containing the on-disk inode X, the page is now locked
-> ntfs_write_mst_block() which clears PageUptodate() on the page to
prevent anyone else getting hold of it whilst it does the write out.
This is necessary as the on-disk inode needs "fixups" applied before
the write to disk which are removed again after the write and
PageUptodate is then set again. It then analyses the page looking
for dirty on-disk inodes and when it finds one it calls
ntfs_may_write_mft_record() to see if it is safe to write this
on-disk inode. This then calls ilookup5() to check if the
corresponding VFS inode is in icache(). This in turn calls ifind()
which waits on the inode lock via wait_on_inode whilst holding the
global inode_lock.
Process 2: pdflush results in a call to __sync_single_inode for the
same VFS inode X on the ntfs volume. This locks the inode (I_LOCK)
then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
read_cache_page() for the page (in page cache of table of inodes
$MFT, inode 0) containing the on-disk inode. This page has
PageUptodate() clear because of Process 1 (see above) so
read_cache_page() blocks when it tries to take the page lock for the
page so it can call ntfs_read_page().
Thus Process 1 is holding the page lock on the page containing the
on-disk inode X and it is waiting on the inode X to be unlocked in
ifind() so it can write the page out and then unlock the page.
And Process 2 is holding the inode lock on inode X and is waiting for
the page to be unlocked so it can call ntfs_readpage() or discover
that Process 1 set PageUptodate() again and use the page.
Thus we have a deadlock due to ifind() waiting on the inode lock.
The solution: The fix is to use the newly introduced
ilookup5_nowait() which does not wait on the inode's lock and hence
avoids the deadlock. This is safe as we do not care about the VFS
inode and only use the fact that it is in the VFS inode cache and the
fact that the vfs and ntfs inodes are one struct in memory to find
the ntfs inode in memory if present. Also, the ntfs inode has its
own locking so it does not matter if the vfs inode is locked.

NTFS: Change ntfs_map_runlist_nolock() to only decompress the mapping pairs
if the requested vcn is inside it. Otherwise we get into problems
when we try to map an out of bounds vcn because we then try to map
the already mapped runlist fragment which causes
ntfs_mapping_pairs_decompress() to fail and return error. Update
ntfs_attr_find_vcn_nolock() accordingly.

NTFS: Fix several occurences of a bug where we would perform 'var & ~const'
with a 64-bit variable and a int, i.e. 32-bit, constant. This causes
the higher order 32-bits of the 64-bit variable to be zeroed. To fix
this cast the 'const' to the same 64-bit type as 'var'.

NTFS: Correct sparse file handling. The compressed values need to be
checked and set in the ntfs inode as done for compressed files
and the compressed size needs to be used for vfs inode->i_blocks
instead of the allocated size, again, as done for compressed files.

NTFS: - Split ntfs_map_runlist() into ntfs_map_runlist() and a non-locking
helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist().
This allows us to map runlist fragments with the runlist lock already
held without having to drop and reacquire it around the call. Adapt
all callers.
- Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked
runlist. This allows us to find runlist elements with the runlist
lock already held without having to drop and reacquire it around the
call. Adapt all callers.
