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).

Some coding style changes. Fix a bug that the array test_tag has insufficient size if the digest size of internal has is bigger than the tag size. The function __fls is undefined for zero argument, this patch fixes undefined behavior if the user sets zero interleave_sectors. Fix the limit of optional arguments to 8. Don't allocate crypt_data on the stack to avoid a BUG with debug kernel. Rename all optional argument names to have underscores rather than dashes. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Since the commit 0cf45031 ("dm raid: add support for the MD RAID0 personality"), the dm-raid subsystem can activate a RAID-0 array. Therefore, add MD_RAID0 to the dependencies of DM_RAID, so that MD_RAID0 will be selected when DM_RAID is selected.

Commit 63c32ed4 ("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. Signed-off-by:

Commit 3a1c1ef2 ("dm raid: enhance status interface and fixup takeover/raid0") added new table line arguments and introduced an 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. Fixes: 3a1c1ef2 ("dm raid: enhance status interface and fixup takeover/raid0") Signed-off-by:

In recovery mode, we don't: - replay the journal - check checksums - allow writes to the device This mode can be used as a last resort for data recovery. The motivation for recovery mode is that when there is a single error in the journal, the user should not lose access to the whole device. Signed-off-by:

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) KEY="9c1185a5c5e9fc54612808977ee8f548b2258d31ddadef707ba62c166051b9e3cd0294c27515f2bccee924e8823ca6e124b8fc3167ed478bca702babe4e130ac" BLOCK_SIZE=4096 # dmsetup create test_crypt --table "0 $DEV_SIZE crypt aes-xts-plain64 $KEY 0 $DEV 0 1 sector_size:$BLOCK_SIZE" # dmsetup table --showkeys test_crypt Signed-off-by:

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 Initialization Vector (IV). The underlying device must support the "DM-DIF-EXT-TAG" dm-integrity profile. The per-bio integrity metadata is allocated by dm-crypt for every bio. Example of low-level mapping table for various types of use: DEV=/dev/sdb SIZE=417792 # Additional HMAC with CBC-ESSIV, key is concatenated encryption key + HMAC key SIZE_INT=389952 dmsetup create x --table "0 $SIZE_INT integrity $DEV 0 32 J 0" dmsetup create y --table "0 $SIZE_INT crypt aes-cbc-essiv:sha256 \ 11ff33c6fb942655efb3e30cf4c0fd95f5ef483afca72166c530ae26151dd83b \ 00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff \ 0 /dev/mapper/x 0 1 integrity:32:hmac(sha256)" # AEAD (Authenticated Encryption with Additional Data) - GCM with random IVs # GCM in kernel uses 96bits IV and we store 128bits auth tag (so 28 bytes metadata space) SIZE_INT=393024 dmsetup create x --table "0 $SIZE_INT integrity $DEV 0 28 J 0" dmsetup create y --table "0 $SIZE_INT crypt aes-gcm-random \ 11ff33c6fb942655efb3e30cf4c0fd95f5ef483afca72166c530ae26151dd83b \ 0 /dev/mapper/x 0 1 integrity:28:aead" # Random IV only for XTS mode (no integrity protection but provides atomic random sector change) SIZE_INT=401272 dmsetup create x --table "0 $SIZE_INT integrity $DEV 0 16 J 0" dmsetup create y --table "0 $SIZE_INT crypt aes-xts-random \ 11ff33c6fb942655efb3e30cf4c0fd95f5ef483afca72166c530ae26151dd83b \ 0 /dev/mapper/x 0 1 integrity:16:none" # Random IV with XTS + HMAC integrity protection SIZE_INT=377656 dmsetup create x --table "0 $SIZE_INT integrity $DEV 0 48 J 0" dmsetup create y --table "0 $SIZE_INT crypt aes-xts-random \ 11ff33c6fb942655efb3e30cf4c0fd95f5ef483afca72166c530ae26151dd83b \ 00112233445566778899aabbccddeeff00112233445566778899aabbccddeeff \ 0 /dev/mapper/x 0 1 integrity:48:hmac(sha256)" 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).

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. Signed-off-by:

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. Signed-off-by:

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)" * tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (26 commits) ARM: deconfig: fix the moxart defconfig ARM: ux500: resume the second core properly arm64: dts: juno: update definition for programmable replicator arm64: dts: exynos: Add regulators for Vbus and Vbus-Boost arm64: dts: exynos: Add USB 3.0 controller node for Exynos7 arm64: dts: exynos: Use macros for pinctrl configuration on Exynos7 pinctrl: dt-bindings: samsung: Add Exynos7 specific pinctrl macro definitions arm64: dts: exynos: Add initial configuration for DISP clocks for TM2/TM2e ARM64: dts: meson-gxbb-p200: add ADC laddered keys ARM64: dts: meson: meson-gx: add the SAR ADC ARM64: dts: meson-gxl: add the pwm_ao_b pin ARM64: dts: meson-gx: add the missing pwm_AO_ab node clk: gxbb: fix CLKID_ETH defined twice ARM64: dts: meson-gxl: rename Nexbox A95x for consistency clk: gxbb: add the SAR ADC clocks and expose them dt-bindings: amlogic: Add WeTek boards ARM64: dts: meson-gxbb: Add support for WeTek Hub and Play dt-bindings: vendor-prefix: Add wetek vendor prefix ARM64: dts: meson-gxm: Rename q200 and q201 DT files for consistency ARM64: dts: meson-gx: Add HDMI HPD/DDC pinctrl nodes ...
