By ignoring the sentinels the cleaner policy is able to write-back dirty
cache data much faster. There is no reason to respect the sentinels,
which denote that a block was changed recently, when using the cleaner
policy given that the cleaner is tasked with writing back all dirty
data.

When loading metadata make sure to set/clear the dirty bits in the cache
core's dirty_bitset as well as the policy.
Otherwise the cache core is unaware that any blocks were dirty when the
cache was last shutdown. A very serious side-effect being that the
cleaner policy would therefore never be tasked with writing back dirty
data from a cache that was in writeback mode (e.g. when switching from
smq policy to cleaner policy when decommissioning a writeback cache).
This fixes a serious data corruption bug associated with writeback mode.

Therefore, add MD_RAID0 to the dependencies of DM_RAID, so that MD_RAID0
will be selected when DM_RAID is selected.

Commit 63c32ed4af ("dm raid: add raid4/5/6 journaling support") added
journal support to close the raid4/5/6 "write hole" -- in terms of
writethrough caching.
Introduce a "journal_mode" feature and use the new
r5c_journal_mode_set() API to add support for switching the journal
device's cache mode between write-through (the current default) and
write-back.
NOTE: If the journal device is not layered on resilent storage and it
fails, write-through mode will cause the "write hole" to reoccur. But
if the journal fails while in write-back mode it will cause data loss
for any dirty cache entries unless resilent storage is used for the
journal.

ordering flaw. The sequence of the raid10_copies and raid10_format
raid parameters got reversed which causes lvm2 userspace to fail by
falsely assuming a changed table line.
Sequence those 2 parameters as before so that old lvm2 can function
properly with new kernels by adjusting the table line output as
documented in Documentation/device-mapper/dm-raid.txt.
Also, add missing version 1.10.1 highlight to the documention.

Add optional "sector_size" parameter that specifies encryption sector
size (atomic unit of block device encryption).
Parameter can be in range 512 - 4096 bytes and must be power of two.
For compatibility reasons, the maximal IO must fit into the page limit,
so the limit is set to the minimal page size possible (4096 bytes).
NOTE: this device cannot yet be handled by cryptsetup if this parameter
is set.
IV for the sector is calculated from the 512 bytes sector offset unless
the iv_large_sectors option is used.
Test script using dmsetup:
DEV="/dev/sdb"
DEV_SIZE=$(blockdev --getsz $DEV)

For the new authenticated encryption we have to support generic composed
modes (combination of encryption algorithm and authenticator) because
this is how the kernel crypto API accesses such algorithms.
To simplify the interface, we accept an algorithm directly in crypto API
format. The new format is recognised by the "capi:" prefix. The
dmcrypt internal IV specification is the same as for the old format.
The crypto API cipher specifications format is:
capi:cipher_api_spec-ivmode[:ivopts]
Examples:
capi:cbc(aes)-essiv:sha256 (equivalent to old aes-cbc-essiv:sha256)
capi:xts(aes)-plain64 (equivalent to old aes-xts-plain64)
Examples of authenticated modes:
capi:gcm(aes)-random
capi:authenc(hmac(sha256),xts(aes))-random
capi:rfc7539(chacha20,poly1305)-random
Authenticated modes can only be configured using the new cipher format.
Note that this format allows user to specify arbitrary combinations that
can be insecure. (Policy decision is done in cryptsetup userspace.)
Authenticated encryption algorithms can be of two types, either native
modes (like GCM) that performs both encryption and authentication
internally, or composed modes where user can compose AEAD with separate
specification of encryption algorithm and authenticator.
For composed mode with HMAC (length-preserving encryption mode like an
XTS and HMAC as an authenticator) we have to calculate HMAC digest size
(the separate authentication key is the same size as the HMAC digest).
Introduce crypt_ctr_auth_cipher() to parse the crypto API string to get
HMAC algorithm and retrieve digest size from it.
Also, for HMAC composed mode we need to parse the crypto API string to
get the cipher mode nested in the specification. For native AEAD mode
(like GCM), we can use crypto_tfm_alg_name() API to get the cipher
specification.
Because the HMAC composed mode is not processed the same as the native
AEAD mode, the CRYPT_MODE_INTEGRITY_HMAC flag is no longer needed and
"hmac" specification for the table integrity argument is removed.

Allow the use of per-sector metadata, provided by the dm-integrity
module, for integrity protection and persistently stored per-sector

Both AEAD and HMAC protection authenticates not only data but also
sector metadata.
HMAC protection is implemented through autenc wrapper (so it is
processed the same way as an authenticated mode).
In HMAC mode there are two keys (concatenated in dm-crypt mapping
table). First is the encryption key and the second is the key for
authentication (HMAC). (It is userspace decision if these keys are
independent or somehow derived.)
The sector request for AEAD/HMAC authenticated encryption looks like this:
|----- AAD -------|------ DATA -------|-- AUTH TAG --|
| (authenticated) | (auth+encryption) | |
| sector_LE | IV | sector in/out | tag in/out |
For writes, the integrity fields are calculated during AEAD encryption
of every sector and stored in bio integrity fields and sent to
underlying dm-integrity target for storage.
For reads, the integrity metadata is verified during AEAD decryption of
every sector (they are filled in by dm-integrity, but the integrity
fields are pre-allocated in dm-crypt).
There is also an experimental support in cryptsetup utility for more
friendly configuration (part of LUKS2 format).
Because the integrity fields are not valid on initial creation, the
device must be "formatted". This can be done by direct-io writes to the
device (e.g. dd in direct-io mode). For now, there is available trivial
tool to do this, see: https://github.com/mbroz/dm_int_tools

The dm-integrity target emulates a block device that has additional
per-sector tags that can be used for storing integrity information.
A general problem with storing integrity tags with every sector is that
writing the sector and the integrity tag must be atomic - i.e. in case of
crash, either both sector and integrity tag or none of them is written.
To guarantee write atomicity the dm-integrity target uses a journal. It
writes sector data and integrity tags into a journal, commits the journal
and then copies the data and integrity tags to their respective location.
The dm-integrity target can be used with the dm-crypt target - in this
situation the dm-crypt target creates the integrity data and passes them
to the dm-integrity target via bio_integrity_payload attached to the bio.
In this mode, the dm-crypt and dm-integrity targets provide authenticated
disk encryption - if the attacker modifies the encrypted device, an I/O
error is returned instead of random data.
The dm-integrity target can also be used as a standalone target, in this
mode it calculates and verifies the integrity tag internally. In this
mode, the dm-integrity target can be used to detect silent data
corruption on the disk or in the I/O path.

The cache policy interfaces have been updated to work well with the new
bio-prison v2 interface's ability to queue work immediately (promotion,
demotion, etc) -- overriding benefit being reduced latency on processing
IO through the cache. Previously such work would be left for the DM
cache core to queue on various lists and then process in batches later
-- this caused a serious delay in latency for IO driven by the cache.
The background tracker code was factored out so that all cache policies
can make use of it.
Also, the "cleaner" policy has been removed and is now a variant of the
smq policy that simply disallows migrations.

set of fixes for stuff which did.
The new stuff is basically lpfc (nvme), qedi and aacraid. The fixes

probably covers some of the failing irq vectors allocation and other
fallout from having the SCSI command allocated as part of the block

Pull libnvdimm fixes from Dan Williams:
"A fix and regression test case for nvdimm namespace label
compatibility.
Details:
- An "nvdimm namespace label" is metadata on an nvdimm that
provisions dimm capacity into a "namespace" that can host a block
device / dax-filesytem, or a device-dax character device.
A namespace is an object that other operating environment and
platform firmware needs to comprehend for capabilities like booting
from an nvdimm.
The label metadata contains a checksum that Linux was not
calculating correctly leading to other environments rejecting the
Linux label.
These have received a build success notification from the kbuild
robot, and a positive test result from Nick who reported the problem"

Pull vfs 'statx()' update from Al Viro.
This adds the new extended stat() interface that internally subsumes our

It also allows for some explicit synchronization information to be
passed to the filesystem, which can be relevant for network filesystems:
is the cached value ok, or do you need open/close consistency, or what?

Pull sched.h split-up from Ingo Molnar:
"The point of these changes is to significantly reduce the

have a cleaner header structure.
After these changes the new <linux/sched.h>'s typical preprocessed
size goes down from a previous ~0.68 MB (~22K lines) to ~0.45 MB (~15K
lines), which is around 40% faster to build on typical configs.
Not much changed from the last version (-v2) posted three weeks ago: I
eliminated quirks, backmerged fixes plus I rebased it to an upstream
SHA1 from yesterday that includes most changes queued up in -next plus
all sched.h changes that were pending from Andrew.
I've re-tested the series both on x86 and on cross-arch defconfigs,
and did a bisectability test at a number of random points.
I tried to test as many build configurations as possible, but some
build breakage is probably still left - but it should be mostly
limited to architectures that have no cross-compiler binaries
available on kernel.org, and non-default configurations"
