dm integrity: conditionally disable "recalculate" feature
commit 5c02406428d5219c367c5f53457698c58bc5f917 upstream. Otherwise a malicious user could (ab)use the "recalculate" feature that makes dm-integrity calculate the checksums in the background while the device is already usable. When the system restarts before all checksums have been calculated, the calculation continues where it was interrupted even if the recalculate feature is not requested the next time the dm device is set up. Disable recalculating if we use internal_hash or journal_hash with a key (e.g. HMAC) and we don't have the "legacy_recalculate" flag. This may break activation of a volume, created by an older kernel, that is not yet fully recalculated -- if this happens, the user should add the "legacy_recalculate" flag to constructor parameters.

ANDROID: dm-bow: Add dm-bow feature
Based on https://www.redhat.com/archives/dm-devel/2019-March/msg00025.html Third version of dm-bow. Key changes: Free list added Support for block sizes other than 4k Handles writes during trim phase, and overlapping trims Integer overflow error Support trims even if underlying device doesn't Numerous small bug fixes bow == backup on write USE CASE: dm-bow takes a snapshot of an existing file system before mounting. The user may, before removing the device, commit the snapshot. Alternatively the user may remove the device and then run a command line utility to restore the device to its original state. dm-bow does not require an external device dm-bow efficiently uses all the available free space on the file system. IMPLEMENTATION: dm-bow can be in one of three states. In state one, the free blocks on the device are identified by issuing an FSTRIM to the filesystem. In state two, any writes cause the overwritten data to be backup up to the available free space. While in this state, the device can be restored by unmounting the filesystem, removing the dm-bow device and running a usermode tool over the underlying device. In state three, the changes are committed, dm-bow is in pass-through mode and the drive can no longer be restored. It is planned to use this driver to enable restoration of a failed update attempt on Android devices using ext4. Test: Can boot Android with userdata mounted on this device. Can commit userdata after SUW has run. Can then reboot, make changes and roll back. Known issues: Mutex is held around entire flush operation, including lengthy I/O. Plan is to convert to state machine with pending queues. Interaction with block encryption is unknown, especially with respect to sector 0. Bug: 119769411 Bug: 129280212 Test: Dogfooded on Wahoo. Ran under Cuttlefish, running VtsKernelBowTest & VtsKernelCheckpointTest tests against 4.19, 4.14 & 4.9 kernels Change-Id: Id70988bbd797ebe3e76fc175094388b423c8da8c Signed-off-by: Paul Lawrence <paullawrence@google.com> |

CHROMIUM: dm: boot time specification of dm=
This is a wrap-up of three patches pending upstream approval.
I'm bundling them because they are interdependent, and it'll be
easier to drop it on rebase later.
1. dm: allow a dm-fs-style device to be shared via dm-ioctl
Integrates feedback from Alisdair, Mike, and Kiyoshi.
Two main changes occur here:
- One function is added which allows for a programmatically created
mapped device to be inserted into the dm-ioctl hash table. This binds
the device to a name and, optional, uuid which is needed by udev and
allows for userspace management of the mapped device.
- dm_table_complete() was extended to handle all of the final
functional changes required for the table to be operational once
called.
2. init: boot to device-mapper targets without an initr*
Add a dm= kernel parameter modeled after the md= parameter from
do_mounts_md. It allows for device-mapper targets to be configured at
boot time for use early in the boot process (as the root device or
otherwise). It also replaces /dev/XXX calls with major:minor opportunistically.
The format is dm="name uuid ro,table line 1,table line 2,...". The
parser expects the comma to be safe to use as a newline substitute but,
otherwise, uses the normal separator of space. Some attempt has been
made to make it forgiving of additional spaces (using skip_spaces()).
A mapped device created during boot will be assigned a minor of 0 and
may be access via /dev/dm-0.
An example dm-linear root with no uuid may look like:
root=/dev/dm-0 dm="lroot none ro, 0 4096 linear /dev/ubdb 0, 4096 4096 linear /dv/ubdc 0"
Once udev is started, /dev/dm-0 will become /dev/mapper/lroot.

dm thin: include metadata_low_watermark threshold in pool status
The metadata low watermark threshold is set by the kernel. But the kernel depends on userspace to extend the thinpool metadata device when the threshold is crossed. Since the metadata low watermark threshold is not visible to userspace, upon receiving an event, userspace cannot tell that the kernel wants the metadata device extended, instead of some other eventing condition. Making it visible (but not settable) enables userspace to affirmatively know the kernel is asking for a metadata device extension, by comparing metadata_low_watermark against nr_free_blocks_metadata, also reported in status. Current solutions like dmeventd have their own thresholds for extending the data and metadata devices, and both devices are checked against their thresholds on each event. This lessens the value of the kernel-set threshold, since userspace will either extend the metadata device sooner, when receiving another event; or will receive the metadata lowater event and do nothing, if dmeventd's threshold is less than the kernel's. (This second case is dangerous. The metadata lowater event will not be re-sent, so no further event will be generated before the metadata device is out if space, unless some other event causes userspace to recheck its thresholds.)

When using external metadata device and internal hash, recalculate the checksums when the device is created - so that dm-integrity doesn't have to overwrite the device.

dm delay: add flush as a third class of IO
Add a new class for dm-delay that delays flush requests. Previously, flushes were delayed as writes, but it caused problems if the user needed to create a device with one or a few slow sectors for the purpose of testing - all flushes would be forwarded to this device and delayed, and that skews the test results. Fix this by allowing to select 0 delay for flushes. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

dm verity: add 'check_at_most_once' option to only validate hashes once
This allows platforms that are CPU/memory contrained to verify data blocks only the first time they are read from the data device, rather than every time. As such, it provides a reduced level of security because only offline tampering of the data device's content will be detected, not online tampering. Hash blocks are still verified each time they are read from the hash device, since verification of hash blocks is less performance critical than data blocks, and a hash block will not be verified any more after all the data blocks it covers have been verified anyway. This option introduces a bitset that is used to check if a block has been validated before or not. A block can be validated more than once as there is no thread protection for the bitset. These changes were developed and tested on entry-level Android Go devices. Signed-off-by: Patrik Torstensson <totte@google.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

dm raid: stop keeping raid set frozen altogether
In order to avoid redoing synchronization/recovery/reshape partially,
the raid set got frozen until after all passed in table line flags had
been cleared. The related table reload sequence had to be precisely
followed, or reshaping may lead to data corruption caused by the active
mapping carrying on with a reshape when the inactive mapping already
had retrieved a stale reshape position.
Harden by retrieving the actual resync/recovery/reshape position
during resume whilst the active table is suspended thus avoiding
to keep the raid set frozen altogether. This prevents superfluous
redoing of an already resynchronized or recovered segment and,
most importantly, potential for redoing of an already reshaped
segment causing data corruption.

dm raid: fix incorrect status output at the end of a "recover" process
There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().

dm zoned: drive-managed zoned block device target
The dm-zoned device mapper target provides transparent write access to zoned block devices (ZBC and ZAC compliant block devices). dm-zoned hides to the device user (a file system or an application doing raw block device accesses) any constraint imposed on write requests by the device, equivalent to a drive-managed zoned block device model. Write requests are processed using a combination of on-disk buffering using the device conventional zones and direct in-place processing for requests aligned to a zone sequential write pointer position. A background reclaim process implemented using dm_kcopyd_copy ensures that conventional zones are always available for executing unaligned write requests. The reclaim process overhead is minimized by managing buffer zones in a least-recently-written order and first targeting the oldest buffer zones. Doing so, blocks under regular write access (such as metadata blocks of a file system) remain stored in conventional zones, resulting in no apparent overhead. dm-zoned implementation focus on simplicity and on minimizing overhead (CPU, memory and storage overhead). For a 14TB host-managed disk with 256 MB zones, dm-zoned memory usage per disk instance is at most about 3 MB and as little as 5 zones will be used internally for storing metadata and performing buffer zone reclaim operations. This is achieved using zone level indirection rather than a full block indirection system for managing block movement between zones. dm-zoned primary target is host-managed zoned block devices but it can also be used with host-aware device models to mitigate potential device-side performance degradation due to excessive random writing. Zoned block devices can be formatted and checked for use with the dm-zoned target using the dmzadm utility available at: https://github.com/hgst/dm-zoned-tools Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Bart Van Assche <bart.vanassche@sandisk.com> [Mike Snitzer partly refactored Damien's original work to cleanup the code] Signed-off-by: Mike Snitzer <snitzer@redhat.com> |

dm integrity: support larger block sizes
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).

dm crypt: introduce new format of cipher with "capi:" prefix
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.

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).

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.

dm raid: fix transient device failure processing
This fix addresses the following 3 failure scenarios: 1) If a (transiently) inaccessible metadata device is being passed into the constructor (e.g. a device tuple '254:4 254:5'), it is processed as if '- -' was given. This erroneously results in a status table line containing '- -', which mistakenly differs from what has been passed in. As a result, userspace libdevmapper puts the device tuple seperate from the RAID device thus not processing the dependencies properly. 2) False health status char 'A' instead of 'D' is emitted on the status status info line for the meta/data device tuple in this metadata device failure case. 3) If the metadata device is accessible when passed into the constructor but the data device (partially) isn't, that leg may be set faulty by the raid personality on access to the (partially) unavailable leg. Restore tried in a second raid device resume on such failed leg (status char 'D') fails after the (partial) leg returned. Fixes for aforementioned failure scenarios: - don't release passed in devices in the constructor thus allowing the status table line to e.g. contain '254:4 254:5' rather than '- -' - emit device status char 'D' rather than 'A' for the device tuple with the failed metadata device on the status info line - when attempting to restore faulty devices in a second resume, allow the device hot remove function to succeed by setting the device to not in-sync In case userspace intentionally passes '- -' into the constructor to avoid that device tuple (e.g. to split off a raid1 leg temporarily for later re-addition), the status table line will correctly show '- -' and the status info line will provide a '-' device health character for the non-defined device tuple.

Documentation/device-mapper: s/getsize/getsz/
According to `man blockdev':
--getsize
Print device size (32-bit!) in sectors.
Deprecated in favor of the --getsz option.
...
--getsz
Get size in 512-byte sectors.
Hence, occurrences of `--getsize' should be replaced with `--getsz',
which this commit has achieved as follows:
$ cd "$repo"
$ git grep -l -e --getsz

dm crypt: add ability to use keys from the kernel key retention service
The kernel key service is a generic way to store keys for the use of other subsystems. Currently there is no way to use kernel keys in dm-crypt. This patch aims to fix that. Instead of key userspace may pass a key description with preceding ':'. So message that constructs encryption mapping now looks like this: <cipher> [<key>|:<key_string>] <iv_offset> <dev_path> <start> [<#opt_params> <opt_params>] where <key_string> is in format: <key_size>:<key_type>:<key_description> Currently we only support two elementary key types: 'user' and 'logon'. Keys may be loaded in dm-crypt either via <key_string> or using classical method and pass the key in hex representation directly. dm-crypt device initialised with a key passed in hex representation may be replaced with key passed in key_string format and vice versa.
