Previously, dm-crypt could use blocks composed of multiple 512b sectors
but it created integrity profile for each 512b sector (it padded it with
zeroes).  Fix dm-crypt so that the integrity profile is sent for each
block not each sector.

The user must use the same block size in the DM crypt and integrity
targets.

The DM integrity block size can now be 512, 1k, 2k or 4k.  Using larger
blocks reduces metadata handling overhead.  The block size can be
configured at table load time using the "block_size:<value>" option;
where <value> is expressed in bytes (defult is still 512 bytes).

It is safe to use larger block sizes with DM integrity, because the
DM integrity journal makes sure that the whole block is updated
atomically even if the underlying device doesn't support atomic writes
of that size (e.g. 4k block ontop of a 512b device).

A dm-crypt on dm-integrity device incorrectly advertises an integrity
profile on the DM crypt device.  It can be seen in the files
"/sys/block/dm-*/integrity/*" that both dm-integrity and dm-crypt target
advertise the integrity profile.  That is incorrect, only the
dm-integrity target should advertise the integrity profile.

A general problem in DM is that if we have a DM device that depends on
another device with an integrity profile, the upper device will always
advertise the integrity profile, even when the target driver doesn't
support handling integrity data.

Most targets don't support integrity data, so we provide a whitelist of
targets that support it (linear, delay and striped).  The targets that
support passing integrity data to the lower device are marked with the
flag DM_TARGET_PASSES_INTEGRITY.  The DM core will now advertise
integrity data on a DM device only if all the targets support the
integrity data.

By ignoring the sentinels the cleaner policy is able to write-back dirty

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.

Commit 63c32ed4 ("dm raid: add raid4/5/6 journaling support") added

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.

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.

  DEV="/dev/sdb"

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

Initialization Vector (IV).  The underlying device must support the

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_toolsSigned-off-by: Milan Broz <gmazyland@gmail.com>

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.

   Florian Westphal.

2) Incorrect sip helper structure initilization that breaks it when
   several ports are used, from Christophe Leroy.

3) Fix incorrect assumption when looking up for matching with adjacent
   intervals in the nft_set_rbtree.

4) Fix broken netlink event error reporting in nf_tables that results
   in misleading ESRCH errors propagated to userspace listeners.

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 Xtensa updates from Max Filippov:

 - clean up bootable image build targets: provide separate 'Image',
   'zImage' and 'uImage' make targets that only build corresponding
   image type. Make 'all' build all images appropriate for a platform

 - allow merging vectors code into .text section as a preparation step
   for XIP support

Pull ARM SoC late DT updates from Arnd Bergmann:
 "These updates have been kept in a separate branch mostly because they
  rely on updates to the respective clk drivers to keep the shared
  header files in sync.

  This includes two branches for arm64 dt updates, both following up on
  earlier changes for the same platforms that are already merged:

  Samsung:
   - add USB3 support in Exynos7
   - minor PM related updates

  Amlogic:
   - new machines: WeTek Set-top-boxes
   - various devices added to DT

  There are also a couple of bugfixes that trickled in since the start
  of the merge window:

   - The moxart_defconfig was not building the intended platform
   - CPU-hotplug was broken on ux500
   - Coresight was broken on Juno (never worked)"
