Convert all create[_singlethread]_work() users to the new
alloc[_ordered]_workqueue(). This conversion is mechanical and
doesn't introduce any behavior change.Signed-off-by: Tejun Heo

kstriped only serves sc->kstriped_ws which runs dm_table_event().
This doesn't need to be executed from an ordered workqueue w/ rescuer.
Drop kstriped and use the system_wq instead. While at it, rename
kstriped_ws to trigger_event so that it's consistent with other dm
modules.Signed-off-by: Tejun Heo

flush_scheduled_work() is being deprecated. Flush the used work
directly instead. In all dm targets, the only work which uses
system_wq is ->trigger_event.Signed-off-by: Tejun Heo

dm_snapshot->queued_bios_work isn't used. Remove ->queued_bios[_work]
from dm_snapshot structure, the flush_queued_bios work function and
ksnapd workqueue.The DM snapshot changes that were going to use the ksnapd workqueue were
either superseded (fix for origin write races) or never completed
(deallocation of invalid snapshot's memory via workqueue).Signed-off-by: Tejun Heo

The device-mapper should not send warning messages to syslog
if a device is not found. This can be done by userspace
according to the returned dm-ioctl error code.So move these messages to debug level and use rate limiting
to not flood syslog.Signed-off-by: Milan Broz

This patch adds a compatible implementation of the block
chaining mode used by the Loop-AES block device encryption
system (http://loop-aes.sourceforge.net/) designed
by Jari Ruusu.It operates on full 512 byte sectors and uses CBC
with an IV derived from the sector number, the data and
optionally extra IV seed.This means that after CBC decryption the first block of sector
must be tweaked according to decrypted data.Loop-AES can use three encryption schemes:
version 1: is plain aes-cbc mode (already compatible)
version 2: uses 64 multikey scheme with own IV generator
version 3: the same as version 2 with additional IV seed
(it uses 65 keys, last key is used as IV seed)The IV generator is here named lmk (Loop-AES multikey)
and for the cipher specification looks like: aes:64-cbc-lmkVersion 2 and 3 is recognised according to length
of provided multi-key string (which is just hexa encoded
"raw key" used in original Loop-AES ioctl).Configuration of the device and decoding key string will
be done in userspace (cryptsetup).
(Loop-AES stores keys in gpg encrypted file, raw keys are
output of simple hashing of lines in this file).Based on an implementation by Max Vozeler:

This patch adds generic multikey handling to be used
in following patch for Loop-AES mode compatibility.This patch extends mapping table to optional keycount and
implements generic multi-key capability.With more keys defined the string is divided into
several sections and these are used for tfms.The tfm is used according to sector offset
(sector 0->tfm[0], sector 1->tfm[1], sector N->tfm[N modulo keycount])
(only power of two values supported for keycount here).Because of tfms per-cpu allocation, this mode can be take
a lot of memory on large smp systems.Signed-off-by: Milan Broz

IV (initialisation vector) can in principle depend not only
on sector but also on plaintext data (or other attributes).Change IV generator interface to work directly with dmreq
structure to allow such dependence in generator.Also add post() function which is called after the crypto
operation.This allows tricky modification of decrypted data or IV
internals.In asynchronous mode the post() can be called after
ctx->sector count was increased so it is needed
to add iv_sector copy directly to dmreq structure.
(N.B. dmreq always include only one sector in scatterlists)Signed-off-by: Milan Broz

If there is enough memory, code can directly submit bio
instead queing this operation in separate thread.Try to alloc bio clone with GFP_NOWAIT and only if it
fails use separate queue (map function cannot block here).Signed-off-by: Milan Broz
Signed-off-by: Alasdair G Kergon -
Currently dm-crypt does all the encryption work for a single dm-crypt
mapping in a single workqueue. This does not scale well when multiple
CPUs are submitting IO at a high rate. The single CPU running the single
thread cannot keep up with the encryption and encrypted IO performance
tanks.This patch changes the crypto workqueue to be per CPU. This means
that as long as the IO submitter (or the interrupt target CPUs
for reads) runs on different CPUs the encryption work will be also
parallel.To avoid a bottleneck on the IO worker I also changed those to be
per-CPU threads.There is still some shared data, so I suspect some bouncing
cache lines. But I haven't done a detailed study on that yet.Signed-off-by: Andi Kleen

Rename cc->cipher_mode to cc->cipher_string and store the whole of the cipher
information so it can easily be printed when processing the DM_DEV_STATUS ioctl.Signed-off-by: Milan Broz

This patch adds a 'version' field to the 'dm_ulog_request'
structure.The 'version' field is taken from a portion of the unused
'padding' field in the 'dm_ulog_request' structure. This
was done to avoid changing the size of the structure and
possibly disrupting backwards compatibility.The version number will help notify user-space daemons
when a change has been made to the kernel/userspace
log API.Signed-off-by: Jonathan Brassow

Allow the device-mapper log's 'mark' and 'clear' requests to be
grouped and processed in a batch. This can significantly reduce the
amount of traffic going between the kernel and userspace (where the
processing daemon resides).Signed-off-by: Jonathan Brassow
Signed-off-by: Mike Snitzer
Signed-off-by: Alasdair G Kergon -
Split the 'flush_list', which contained a mix of both 'mark' and 'clear'
requests, into two distinct lists ('mark_list' and 'clear_list').The device mapper log implementations (used by various DM targets) are
allowed to cache 'mark' and 'clear' requests until a 'flush' is
received. Until now, these cached requests were kept in the same list.
They will now be put into distinct lists to facilitate group processing
of these requests (in the next patch).Signed-off-by: Jonathan Brassow

Make kcopyd merge more I/O requests by using device unplugging.
Without this patch, each I/O request is dispatched separately to the device.
If the device supports tagged queuing, there are many small requests sent
to the device. To improve performance, this patch will batch as many requests
as possible, allowing the queue to merge consecutive requests, and send them
to the device at once.In my tests (15k SCSI disk), this patch improves sequential write throughput:
Sequential write throughput (chunksize of 4k, 32k, 512k)
unpatched: 15.2, 18.5, 17.5 MB/s
patched: 14.4, 22.6, 23.0 MB/sIn most common uses (snapshot or two-way mirror), kcopyd is only used for
two devices, one for reading and the other for writing, thus this optimization
is implemented only for two devices. The optimization may be extended to n-way
mirrors with some code complexity increase.We keep track of two block devices to unplug (one for read and the
other for write) and unplug them when exiting "do_work" thread. If
there are more devices used (in theory it could happen, in practice it
is rare), we unplug immediately.Signed-off-by: Mikulas Patocka

This patch replaces dm_mutex with _minor_lock in dm_blk_close()
and then removes it.During the BKL conversion, commit 6e9624b8caec290d28b4c6d9ec75749df6372b87
(block: push down BKL into .open and .release) pushed lock_kernel()
down into dm_blk_open/close calls.
Commit 2a48fc0ab24241755dc93bfd4f01d68efab47f5a
(block: autoconvert trivial BKL users to private mutex) converted it to a
local mutex, but _minor_lock is sufficient.Signed-off-by: Milan Broz

Allow the uuid of a mapped device to be set after device creation.
Previously the uuid (which is optional) could only be set by
DM_DEV_CREATE. If no uuid was supplied it could not be set later.Sometimes it's necessary to create the device before the uuid is known,
and in such cases the uuid must be filled in after the creation.This patch extends DM_DEV_RENAME to accept a uuid accompanied by
a new flag DM_UUID_FLAG. This can only be done once and if no
uuid was previously supplied. It cannot be used to change an
existing uuid.DM_VERSION_MINOR is also bumped to 19 to indicate this interface
extension is available.Signed-off-by: Peter Jones

Remove the REQ_SYNC flag to improve write throughput when writing
to the origin with a snapshot on the same device (using the CFQ I/O
scheduler).Sequential write throughput (chunksize of 4k, 32k, 512k)
unpatched: 8.5, 8.6, 9.3 MB/s
patched: 15.2, 18.5, 17.5 MB/sSnapshot exception reallocations are triggered by writes that are
usually async, so mark the associated dm_io_request as async as well.
This helps when using the CFQ I/O scheduler because it has separate
queues for sync and async I/O. Async is optimized for throughput; sync
for latency. With this change we're consciously favoring throughput over
latency.Signed-off-by: Mikulas Patocka

dm: Call blk_abort_queue on failed pathsMultipath began to use blk_abort_queue() to allow for
lower latency path deactivation. This was found to
cause list corruption:the cmd gets blk_abort_queued/timedout run on it and the scsi eh
somehow is able to complete and run scsi_queue_insert while
scsi_request_fn is still trying to process the request.https://www.redhat.com/archives/dm-devel/2010-November/msg00085.html

No longer needlessly hold md->bdev->bd_inode->i_mutex when changing the
size of a DM device. This additional locking is unnecessary because
i_size_write() is already protected by the existing critical section in
dm_swap_table(). DM already has a reference on md->bdev so the
associated bd_inode may be changed without lifetime concerns.A negative side-effect of having held md->bdev->bd_inode->i_mutex was
that a concurrent DM device resize and flush (via fsync) would deadlock.
Dropping md->bdev->bd_inode->i_mutex eliminates this potential for
deadlock. The following reproducer no longer deadlocks:
