Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

NTFS: The big ntfs write(2) rewrite has arrived. We now implement our own file operations ->write(), ->aio_write(), and ->writev() for regular files. This replaces the old use of generic_file_write(), et al and the address space operations ->prepare_write and ->commit_write. This means that both sparse and non-sparse (unencrypted and uncompressed) files can now be extended using the normal write(2) code path. There are two limitations at present and these are that we never create sparse files and that we only have limited support for highly fragmented files, i.e. ones whose data attribute is split across multiple extents. When such a case is encountered, EOPNOTSUPP is returned. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

NTFS: Change ntfs_map_runlist_nolock() to also take an optional attribute search context. This allows calling it with the mft record mapped. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 13:44:48 +01:00
NTFS: - Change {__,}ntfs_cluster_free() to also take an optional attribute search context as argument. This allows calling it with the mft record mapped. Update all callers. - Fix potential deadlock in ntfs_mft_data_extend_allocation_nolock() error handling by passing in the active search context when calling ntfs_cluster_free(). Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 14:24:21 +01:00
NTFS: - Change ntfs_cluster_alloc() to take an extra boolean parameter specifying whether the cluster are being allocated to extend an attribute or to fill a hole. - Change ntfs_attr_make_non_resident() to call ntfs_cluster_alloc() with @is_extension set to TRUE and remove the runlist terminator fixup code as this is now done by ntfs_cluster_alloc(). Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 14:36:56 +01:00
NTFS: Change ntfs_attr_make_non_resident to take the attribute value size as an extra parameter. This is needed since we need to know the size before we can map the mft record and our callers always know it. The reason we cannot simply read the size from the vfs inode i_size is that this is not necessarily uptodate. This happens when ntfs_attr_make_non_resident() is called in the ->truncate call path. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 14:48:20 +01:00
NTFS: Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks which is zero for a resident attribute but should no longer be zero once the attribute is non-resident as it then has real clusters allocated. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 14:57:15 +01:00
NTFS: Add fs/ntfs/attrib.[hc]::ntfs_attr_extend_allocation(), a function to extend the allocation of an attributes. Optionally, the data size, but not the initialized size can be extended, too. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 15:18:56 +01:00
NTFS: Implement fs/ntfs/inode.[hc]::ntfs_truncate(). It only supports uncompressed and unencrypted files. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 15:39:02 +01:00
NTFS: The big ntfs write(2) rewrite has arrived. We now implement our own file operations ->write(), ->aio_write(), and ->writev() for regular files. This replaces the old use of generic_file_write(), et al and the address space operations ->prepare_write and ->commit_write. This means that both sparse and non-sparse (unencrypted and uncompressed) files can now be extended using the normal write(2) code path. There are two limitations at present and these are that we never create sparse files and that we only have limited support for highly fragmented files, i.e. ones whose data attribute is split across multiple extents.

2005-10-11 15:40:40 +01:00
NTFS: Enable ATTR_SIZE attribute changes in ntfs_setattr(). This completes the initial implementation of file truncation. Now both open(2)ing a file with the O_TRUNC flag and the {,f}truncate(2) system calls will resize a file appropriately. The limitations are that only uncompressed and unencrypted files are supported. Also, there is only very limited support for highly fragmented files (the ones whose $DATA attribute is split into multiple attribute extents). Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-10-04 16:01:06 +01:00
NTFS: In attrib.c::ntfs_attr_set() call balance_dirty_pages_ratelimited() and cond_resched() in the main loop as we could be dirtying a lot of pages and this ensures we play nice with the VM and the system as a whole. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

2005-09-08 23:01:16 +01:00
NTFS: Support more clean journal ($LogFile) states. - Support journals ($LogFile) which have been modified by chkdsk. This means users can boot into Windows after we marked the volume dirty. The Windows boot will run chkdsk and then reboot. The user can then immediately boot into Linux rather than having to do a full Windows boot first before rebooting into Linux and we will recognize such a journal and empty it as it is clean by definition. - Support journals ($LogFile) with only one restart page as well as journals with two different restart pages. We sanity check both and either use the only sane one or the more recent one of the two in the case that both are valid. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 16:12:28 +01:00
NTFS: More $LogFile handling fixes: when chkdsk has been run, it can leave the restart pages in the journal without multi sector transfer protection fixups (i.e. the update sequence array is empty and in fact does not exist). Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

2005-09-08 16:12:28 +01:00
NTFS: Allow highmem kmalloc() in ntfs_malloc_nofs() and add _nofail() version. - Modify fs/ntfs/malloc.h::ntfs_malloc_nofs() to do the kmalloc() based allocations with __GFP_HIGHMEM, analogous to how the vmalloc() based allocations are done. - Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and hence cannot fail. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 16:28:25 +01:00
NTFS: Use ntfs_malloc_nofs_nofail() in runlist.c::ntfs_runlists_merge() in the two critical regions. This means we no longer need to panic() when the allocation fails as it now cannot fail. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 16:33:12 +01:00

2005-09-08 20:26:34 +01:00
NTFS: Fix a bug in fs/ntfs/index.c::ntfs_index_lookup(). When the returned index entry is in the index root, we forgot to set the @ir pointer in the index context. Thanks for Yura Pakhuchiy for finding this bug. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

2005-09-08 20:40:32 +01:00
NTFS: Fix several bugs in fs/ntfs/attrib.c. - Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect access to the allocated size in the ntfs inode with the size lock. - Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to return LCN_ENOENT when there is no runlist and the allocated size is zero. - Fix load_attribute_list() to handle the case of a NULL runlist. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 20:56:09 +01:00
NTFS: Fix handling of sparse attributes in ntfs_attr_make_non_resident(). Also, add BUG() checks to ntfs_attr_make_non_resident() and ntfs_attr_set() to ensure that these functions are never called for compressed or encrypted attributes. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 21:01:17 +01:00
NTFS: Fix cluster (de)allocators to work when the runlist is NULL and more importantly to take a locked runlist rather than them locking it which leads to lock reversal. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
2005-09-08 21:09:06 +01:00

2005-09-08 21:25:48 +01:00

2005-09-26 10:48:54 +01:00
NTFS: Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the count to become negative and hence we had a wild memset() scribbling all over the system's ram. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

2005-02-03 12:04:36 +00:00
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.

2005-03-03 13:44:15 +00:00
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: 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. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
