If the b_iodone handler is run in calling context in xfs_buf_iorequest we can run into a recursion where xfs_buf_iodone_callbacks keeps calling back into xfs_buf_iorequest because an I/O error happened, which keeps calling back into xfs_buf_iorequest. This chain will usually not take long because the filesystem gets shut down because of log I/O errors, but even over a short time it can cause stack overflows if run on the same context. As a short term workaround make sure we always call the iodone handler in workqueue context.

Almost all metadata allocations come from shallow stack usage situations. Avoid the overhead of switching the allocation to a workqueue as we are not in danger of running out of stack when making these allocations.

discontigous buffer in separate buffer format structures. This means log recovery will recover all the changes on a per segment basis without requiring any knowledge of the fact that it was logged from a compound buffer. To do this, we need to be able to determine what buffer segment any given offset into the compound buffer sits over. This enables us to translate the dirty bitmap in the number of separate buffer format structures required. We also need to be able to determine the number of bitmap elements that a given buffer segment has, as this determines the size of the buffer format structure. Hence we need to be able to determine the both the start offset into the buffer and the length of a given segment to be able to calculate this. With this information, we can preallocate, build and format the correct log vector array for each segment in a compound buffer to appear exactly the same as individually logged buffers in the log.

To support discontiguous buffers in the buffer cache, we need to separate the cache index variables from the I/O map. While this is currently a 1:1 mapping, discontiguous buffer support will break this relationship. However, for caching purposes, we can still treat them the same as a contiguous buffer - the block number of the first block and the length of the buffer - as that is still a unique representation. Also, the only way we will ever access the discontiguous regions of buffers is via bulding the complete buffer in the first place, so using the initial block number and entire buffer length is a sane way to index the buffers. Add a block mapping vector construct to the xfs_buf and use it in the places where we are doing IO instead of the current b_bn/b_length variables.

The struct xfs_buf_log_format wants to think the dirty bitmap is variable sized. In fact, it is variable size on disk simply due to the way we map it from the in-memory structure, but we still just use a fixed size memory allocation for the in-memory structure. Hence it makes no sense to set the function up as a variable sized structure when we already know it's maximum size, and we always allocate it as such. Simplify the structure by making the dirty bitmap a fixed sized array and just using the size of the structure for the allocation size. This will make it much simpler to allocate and manipulate an array of format structures for discontiguous buffer support. The previous struct xfs_buf_log_item size according to /proc/slabinfo was 224 bytes. pahole doesn't give the same size because of the variable size definition. With this modification, pahole reports the same as /proc/slabinfo: /* size: 224, cachelines: 4, members: 6 */ Because the xfs_buf_log_item size is now determined by the maximum supported block size we introduce a dependency on xfs_alloc_btree.h. Avoid this dependency by moving the idefines for the maximum block sizes supported to xfs_types.h with all the other max/min type defines to avoid any new dependencies.

Commit de1cbee4 which removed b_file_offset in favor of b_bn introduced a bug causing xfs_buf_allocate_memory() to overestimate the number of necessary pages. The problem is that xfs_buf_alloc() sets b_bn to -1 and thus effectively every buffer is straddling a page boundary which causes xfs_buf_allocate_memory() to allocate two pages and use vmalloc() for access which is unnecessary. Dave says xfs_buf_alloc() doesn't need to set b_bn to -1 anymore since the buffer is inserted into the cache only after being fully initialized now. So just make xfs_buf_alloc() fill in proper block number from the beginning.

An inode in the AIL can be flush locked and marked stale if a cluster free transaction occurs at the right time. The inode item is then marked as flushing, which causes xfsaild to spin and leaves the filesystem stalled. This is reproduced by running xfstests 273 in a loop for an extended period of time. Check for stale inodes before the flush lock. This marks the inode as pinned, leads to a log flush and allows the filesystem to proceed.

On filesytems with a block size smaller than PAGE_SIZE we currently have a problem with unwritten extents. If a we have multi-block page for which an unwritten extent has been allocated, and only some of the buffers have been written to, and they are not contiguous, we can expose stale data from disk in the blocks between the writes after extent conversion. Example of a page with unwritten and real data. buffer content 0 empty b_state = 0 1 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 2 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 3 empty b_state = 0 4 empty b_state = 0 5 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 6 DATA b_state = 0x1023 Uptodate,Dirty,Mapped,Unwritten 7 empty b_state = 0 Buffers 1, 2, 5, and 6 have been written to, leaving 0, 3, 4, and 7 empty. Currently buffers 1, 2, 5, and 6 are added to a single ioend, and when IO has completed, extent conversion creates a real extent from block 1 through block 6, leaving 0 and 7 unwritten. However buffers 3 and 4 were not written to disk, so stale data is exposed from those blocks on a subsequent read. Fix this by setting iomap_valid = 0 when we find a buffer that is not Uptodate. This ensures that buffers 5 and 6 are not added to the same ioend as buffers 1 and 2. Later these blocks will be converted into two separate real extents, leaving the blocks in between unwritten.

This patch implements two new messages that can be sent to the thin pool target allowing it to take a snapshot of the _metadata_. This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.
