| * ocfs2: avoid unaligned access to dqc_bitmapAkinobu Mita2011-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The dqc_bitmap field of struct ocfs2_local_disk_chunk is 32-bit aligned, but not 64-bit aligned. The dqc_bitmap is accessed by ocfs2_set_bit(), ocfs2_clear_bit(), ocfs2_test_bit(), or ocfs2_find_next_zero_bit(). These are wrapper macros for ext2_*_bit() which need to take an unsigned long aligned address (though some architectures are able to handle unaligned address correctly) So some 64bit architectures may not be able to access the dqc_bitmap correctly. This avoids such unaligned access by using another wrapper functions for ext2_*_bit(). The code is taken from fs/ext4/mballoc.c which also need to handle unaligned bitmap access.

| | | | | | | | | | | | | | | | | | | | Since ocfs2 has no ->write_inode method, there's no point in calling write_inode_now() from ocfs2_cleanup_delete_inode(). Use filemap_write_and_wait() instead.

| * ocfs2: Add a missing journal credit in ocfs2_link_credits() -v2Xiaowei.Hu2011-11-17

The credit calculation in ocfs2_link_credits() did not correctly account for adding an entry that exactly fills a dirblock that triggers removing that dirblock by changing the pointer in the previous block in the list. The credit calculation did not account for that previous block. To expose, do: mkfs.ocfs2 -b 512 -M local /dev/sdX mount /dev/sdX /ocfs2 mkdir /ocfs2/linkdir touch /ocfs2/linkdir/file1 for i in `seq 1 29` ; do link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklink$i; done rm -f /ocfs2/linkdir/linklinklinklinklinklink10 sleep 8 link /ocfs2/linkdir/file1 /ocfs2/linkdir/linklinklinklinklinklinkaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa Note: The link names have been crafted for a 512 byte blocksize. Reproducing with a larger blocksize will require longer (or more) links. The sleep is important. We want jbd2 to commit the transaction so that the missing block does not piggy back on account of the previous transaction.

| * ocfs2: make direntry invalid when deleting itWengang Wang2011-11-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we deleting a direntry from a directory, if it's the first in a block we invalid it by setting inode to 0; otherwise, we merge the deleted one to the prior and contiguous direntry. And we don't truncate directories. There is a problem for the later case since inode is not set to 0. This problem happens when the caller passes a file position as parameter to ocfs2_dir_foreach_blk(). If the position happens to point to a stale(not the first, deleted in betweens of ocfs2_dir_foreach_blk()s) direntry, we are not able to recognize its staleness. So that we treat it as a live one wrongly. The fix is to set inode to 0 in both cases indicating the direntry is stale. This won't introduce additional IOs.

| | * ocfs2: Implement llseek()Sunil Mushran2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ocfs2 implements its own llseek() to provide the SEEK_HOLE/SEEK_DATA functionality. SEEK_HOLE sets the file pointer to the start of either a hole or an unwritten (preallocated) extent, that is greater than or equal to the supplied offset. SEEK_DATA sets the file pointer to the start of an allocated extent (not unwritten) that is greater than or equal to the supplied offset. If the supplied offset is on a desired region, then the file pointer is set to it. Offsets greater than or equal to the file size return -ENXIO. Unwritten (preallocated) extents are considered holes because the file system treats reads to such regions in the same way as it does to holes. Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In dlmlock_remote(), we wait for the resource to stop being active before setting the inprogress flag. Active includes recovery, migration, etc. The problem here is that if the resource was being recovered or migrated, the new owner could very well be that node itself (and thus not a remote node). This problem was observed in Oracle bug#12583620. The error messages observed were as follows: dlm_send_remote_lock_request:337 ERROR: Error -40 (ELOOP) when sending message 503 (key 0xd6d8c7) to node 2 dlmlock_remote:271 ERROR: dlm status = DLM_BADARGS dlmlock:751 ERROR: dlm status = DLM_BADARGS Signed-off-by: Sunil Mushran <sunil.mushran@oracle.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The inflight reference count, in the lock resource, is taken to pin the resource in memory. We take it when a new resource is created and release it after a lock is attached to it. We do this to prevent the resource from getting purged prematurely. Earlier this reference count was being taken for locally mastered resources only. This patch extends the same functionality for remotely mastered ones. We are doing this because the same premature purging could occur for remotely mastered resources if the remote node were to die before completion of the create lock. Fix for Oracle bug#12405575.

| * | ocfs2: Avoid livelock in ocfs2_readpage()Jan Kara2011-07-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When someone writes to an inode, readers accessing the same inode via ocfs2_readpage() just busyloop trying to get ip_alloc_sem because do_generic_file_read() looks up the page again and retries ->readpage() when previous attempt failed with AOP_TRUNCATED_PAGE. When there are enough readers, they can occupy all CPUs and in non-preempt kernel the system is deadlocked because writer holding ip_alloc_sem is never run to release the semaphore. Fix the problem by making reader block on ip_alloc_sem to break the busy loop. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Joel Becker <jlbec@evilplan.org>

Ext4 (e9e3bcecf44c04b9e6b505fd8e2eb9cea58fb94d) and xfs recently had to fix similar issues. In our case what happens is that we can have an outstanding aio on a region and if a write comes in with some bytes overlapping the original aio we may decide to read that region into a page before continuing (typically because of buffered-io fallback). Since we have no ordering guarantees with the aio, we can read stale or bad data into the page and then write it back out. If the i/o is page and block aligned, then we avoid this issue as there won't be any need to read data from disk. I took the same approach as Eric in the ext4 patch and introduced some serialization of unaligned async direct i/o. I don't expect this to have an effect on the most common cases of AIO. Unaligned aio will be slower though, but that's far more acceptable than data corruption. Signed-off-by: Mark Fasheh <mfasheh@suse.com> Signed-off-by: Joel Becker <jlbec@evilplan.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | | | fs: take the ACL checks to common codeChristoph Hellwig2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | new helper: posix_acl_create(&acl, gfp, mode_p). Replaces acl with modified clone, on failure releases acl and replaces with NULL. Returns 0 or -ve on error. All callers of posix_acl_create_masq() switched.

* | | | vfs: move ACL cache lookup into generic codeLinus Torvalds2011-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
