* ocfs2: Fix ocfs2_read_quota_block() error handling.Joel Becker2009-01-054-48/+60
| | | | | | | | | | | | | | | | | | | ocfs2_bread() has become ocfs2_read_virt_blocks(), with a prototype to match ocfs2_read_blocks(). The quota code, converting from ocfs2_bread(), wraps the call to ocfs2_read_virt_blocks() in ocfs2_read_quota_block(). Unfortunately, the prototype of ocfs2_read_quota_block() matches the old prototype of ocfs2_bread(). The problem is that ocfs2_bread() returned the buffer head, and callers assumed that a NULL pointer was indicative of error. It wasn't. This is why ocfs2_bread() took an int*err argument as well. The new prototype of ocfs2_read_virt_blocks() avoids this error handling confusion. Let's change ocfs2_read_quota_block() to match.

* ocfs2: Implementation of local and global quota file handlingJan Kara2009-01-0513-5/+2165
| | | | | | | | | | | | | | | | | For each quota type each node has local quota file. In this file it stores changes users have made to disk usage via this node. Once in a while this information is synced to global file (and thus with other nodes) so that limits enforcement at least aproximately works. Global quota files contain all the information about usage and limits. It's mostly handled by the generic VFS code (which implements a trie of structures inside a quota file). We only have to provide functions to convert structures from on-disk format to in-memory one. We also have to provide wrappers for various quota functions starting transactions and acquiring necessary cluster locks before the actual IO is really started.

| | | | | | | | | | During an xattr set, when we move a xattr which was stored in inode to the outside bucket, we have to delete it and it will use the old value of xis->not_found. xis->not_found is removed by ocfs2_calc_xattr_set_need though, so we must restore it.

* ocfs2: Wrap virtual block reads in ocfs2_read_virt_blocks()Joel Becker2009-01-052-0/+95
| | | | | | | | | | | | | | | | | | | | | The ocfs2_read_dir_block() function really maps an inode's virtual blocks to physical ones before calling ocfs2_read_blocks(). Let's extract that to common code, because other places might want to do that. Other than the block number being virtual, ocfs2_read_virt_blocks() takes the same arguments as ocfs2_read_blocks(). It converts those virtual block numbers to physical before calling ocfs2_read_blocks() directly. If the blocks asked for are discontiguous, this can mean multiple calls to ocfs2_read_blocks(), but this is mostly hidden from the caller. Like ocfs2_read_blocks(), the caller can pass in an existing buffer_head. This is usually done to pick up some readahead I/O. ocfs2_read_virt_blocks() checks the buffer_head's block number against the extent map - it must match.

* ocfs2: Validate metadata only when it's read from disk.Joel Becker2009-01-0510-97/+149
| | | | | | | | | | | | | | | | | | | | Add an optional validation hook to ocfs2_read_blocks(). Now the validation function is only called when a block was actually read off of disk. It is not called when the buffer was in cache. We add a buffer state bit BH_NeedsValidate to flag these buffers. It must always be one higher than the last JBD2 buffer state bit. The dinode, dirblock, extent_block, and xattr_block validators are lifted to this scheme directly. The group_descriptor validator needs to be split into two pieces. The first part only needs the gd buffer and is passed to ocfs2_read_block(). The second part requires the dinode as well, and is called every time. It's only 3 compares, so it's tiny. This also allows us to clean up the non-fatal gd check used by resize.c. It now has no magic argument.

* ocfs2: Wrap inode block reads in a dedicated function.Joel Becker2009-01-0512-97/+136
| | | | | | | | | | | | | | | | | | | | | | | The ocfs2 code currently reads inodes off disk with a simple ocfs2_read_block() call. Each place that does this has a different set of sanity checks it performs. Some check only the signature. A couple validate the block number (the block read vs di->i_blkno). A couple others check for VALID_FL. Only one place validates i_fs_generation. A couple check nothing. Even when an error is found, they don't all do the same thing. We wrap inode reading into ocfs2_read_inode_block(). This will validate all the above fields, going readonly if they are invalid (they never should be). ocfs2_read_inode_block_full() is provided for the places that want to pass read_block flags. Every caller is passing a struct inode with a valid ip_blkno, so we don't need a separate blkno argument either. We will remove the validation checks from the rest of the code in a later commit, as they are no longer necessary.

| | | | | | | | | | | | | | | | | | | | | | | | | | In current ocfs2/xattr, the whole xattr set is divided into many steps are many transaction are used, this make the xattr set process isn't like a real transaction, so this patch try to merge all the transaction into one. Another benefit is that acl can use it easily now. I don't merge the transaction of deleting xattr when we remove an inode. The reason is that if we have a large number of xattrs and every xattrs has large values(large enough for outside storage), the whole transaction will be very huge and it looks like jbd can't handle it(I meet with a jbd complain once). And the old inode removal is also divided into many steps, so I'd like to leave as it is. Note: In xattr set, I try to avoid ocfs2_extend_trans since if the credits aren't enough for the extension, it will commit all the dirty blocks and create a new transaction which may lead to inconsistency in metadata.

| | | | | | | | | | | | | | | | | | | | | | | | Now in ocfs2 xattr set, the whole process are divided into many small parts and they are wrapped into diffrent transactions and it make the set doesn't look like a real transaction. So we want to integrate it into a real one. In some cases we will allocate some clusters and free some in just one transaction. e.g, one xattr is larger than inline size, so it and its value root is stored within the inode while the value is outside in a cluster. Then we try to update it with a smaller value(larger than the size of root but smaller than inline size), we may need to free the outside cluster while allocate a new bucket(one cluster) since now the inode may be full. The old solution will lock the global_bitmap(if the local alloc failed in stress test) and then the truncate log. This will cause a ABBA lock with truncate log flush. This patch add the clusters free in dealloc_ctxt, so that we can record the free clusters during the transaction and then free it after we release the global_bitmap in xattr set.

* ocfs2: Use buckets in ocfs2_xattr_create_index_block().Joel Becker2009-01-051-82/+32
| | | | | | | | | | Use the ocfs2_xattr_bucket abstraction in ocfs2_xattr_create_index_block() and its helpers. We get more efficient reads, a lot less buffer_head munging, and nicer code to boot. While we're at it, ocfs2_xattr_update_xattr_search() becomes void. Signed-off-by: Joel Becker <joel.becker@oracle.com> Signed-off-by: Mark Fasheh <mfasheh@suse.com>
