@@ -1,199 +0,0 @@
-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 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.
-
-
-When loading the target for the first time, the kernel driver will format
-the device. But it will only format the device if the superblock contains
-zeroes. If the superblock is neither valid nor zeroed, the dm-integrity
-target can't be loaded.
-
-To use the target for the first time:
-1. overwrite the superblock with zeroes
-2. load the dm-integrity target with one-sector size, the kernel driver
-	will format the device
-3. unload the dm-integrity target
-4. read the "provided_data_sectors" value from the superblock
-5. load the dm-integrity target with the the target size
-	"provided_data_sectors"
-6. if you want to use dm-integrity with dm-crypt, load the dm-crypt target
-	with the size "provided_data_sectors"
-
-
-Target arguments:
-
-1. the underlying block device
-
-2. the number of reserved sector at the beginning of the device - the
-	dm-integrity won't read of write these sectors
-
-3. the size of the integrity tag (if "-" is used, the size is taken from
-	the internal-hash algorithm)
-
-4. mode:
-	D - direct writes (without journal) - in this mode, journaling is
-		not used and data sectors and integrity tags are written
-		separately. In case of crash, it is possible that the data
-		and integrity tag doesn't match.
-	J - journaled writes - data and integrity tags are written to the
-		journal and atomicity is guaranteed. In case of crash,
-		either both data and tag or none of them are written. The
-		journaled mode degrades write throughput twice because the
-		data have to be written twice.
-	R - recovery mode - in this mode, journal is not replayed,
-		checksums are not checked and writes to the device are not
-		allowed. This mode is useful for data recovery if the
-		device cannot be activated in any of the other standard
-		modes.
-
-5. the number of additional arguments
-
-Additional arguments:
-
-journal_sectors:number
-	The size of journal, this argument is used only if formatting the
-	device. If the device is already formatted, the value from the
-	superblock is used.
-
-interleave_sectors:number
-	The number of interleaved sectors. This values is rounded down to
-	a power of two. If the device is already formatted, the value from
-	the superblock is used.
-
-buffer_sectors:number
-	The number of sectors in one buffer. The value is rounded down to
-	a power of two.
-
-	The tag area is accessed using buffers, the buffer size is
-	configurable. The large buffer size means that the I/O size will
-	be larger, but there could be less I/Os issued.
-
-journal_watermark:number
-	The journal watermark in percents. When the size of the journal
-	exceeds this watermark, the thread that flushes the journal will
-	be started.
-
-commit_time:number
-	Commit time in milliseconds. When this time passes, the journal is
-	written. The journal is also written immediatelly if the FLUSH
-	request is received.
-
-internal_hash:algorithm(:key)	(the key is optional)
-	Use internal hash or crc.
-	When this argument is used, the dm-integrity target won't accept
-	integrity tags from the upper target, but it will automatically
-	generate and verify the integrity tags.
-
-	You can use a crc algorithm (such as crc32), then integrity target
-	will protect the data against accidental corruption.
-	You can also use a hmac algorithm (for example
-	"hmac(sha256):0123456789abcdef"), in this mode it will provide
-	cryptographic authentication of the data without encryption.

-	* integrity tag size
-	* the number of journal sections

-	  provides (i.e. the size of the device minus the size of all
-	  metadata and padding). The user of this target should not send
-	  bios that access data beyond the "provided data sectors" limit.
-	* flags - a flag is set if journal_mac is used
-* journal
-	The journal is divided into sections, each section contains:
-	* metadata area (4kiB), it contains journal entries
-	  every journal entry contains:
-		* logical sector (specifies where the data and tag should
-		  be written)
-		* last 8 bytes of data
-		* integrity tag (the size is specified in the superblock)
-	    every metadata sector ends with
-		* mac (8-bytes), all the macs in 8 metadata sectors form a
-		  64-byte value. It is used to store hmac of sector
-		  numbers in the journal section, to protect against a
-		  possibility that the attacker tampers with sector
-		  numbers in the journal.
-		* commit id
-	* data area (the size is variable; it depends on how many journal

-	    every sector in the data area contains:
-		* data (504 bytes of data, the last 8 bytes are stored in
-		  the journal entry)
-		* commit id
-	To test if the whole journal section was written correctly, every
-	512-byte sector of the journal ends with 8-byte commit id. If the
-	commit id matches on all sectors in a journal section, then it is
-	assumed that the section was written correctly. If the commit id
-	doesn't match, the section was written partially and it should not

-* one or more runs of interleaved tags and data. Each run contains:
-	* tag area - it contains integrity tags. There is one tag for each

-dm-zoned
-========
-
-The dm-zoned device mapper target exposes a zoned block device (ZBC and
-ZAC compliant devices) as a regular block device without any write
-pattern constraints. In effect, it implements a drive-managed zoned
-block device which hides from the user (a file system or an application
-doing raw block device accesses) the sequential write constraints of
-host-managed zoned block devices and can mitigate the potential
-device-side performance degradation due to excessive random writes on
-host-aware zoned block devices.
-
-For a more detailed description of the zoned block device models and
-their constraints see (for SCSI devices):
-
-http://www.t10.org/drafts.htm#ZBC_Family
-
-and (for ATA devices):
-
-http://www.t13.org/Documents/UploadedDocuments/docs2015/di537r05-Zoned_Device_ATA_Command_Set_ZAC.pdf
-
-The dm-zoned implementation is simple and minimizes system overhead (CPU
-and memory usage as well as storage capacity loss). For a 10TB
-host-managed disk with 256 MB zones, dm-zoned memory usage per disk
-instance is at most 4.5 MB and as little as 5 zones will be used
-internally for storing metadata and performaing reclaim operations.
-
-dm-zoned target devices are formatted and checked using the dmzadm
-utility available at:
-
-https://github.com/hgst/dm-zoned-tools
-
-Algorithm
-=========
-
-dm-zoned implements an on-disk buffering scheme to handle non-sequential
-write accesses to the sequential zones of a zoned block device.
-Conventional zones are used for caching as well as for storing internal
-metadata.
-
-The zones of the device are separated into 2 types:
-
-1) Metadata zones: these are conventional zones used to store metadata.
-Metadata zones are not reported as useable capacity to the user.
-
-2) Data zones: all remaining zones, the vast majority of which will be
-sequential zones used exclusively to store user data. The conventional
-zones of the device may be used also for buffering user random writes.
-Data in these zones may be directly mapped to the conventional zone, but
-later moved to a sequential zone so that the conventional zone can be
-reused for buffering incoming random writes.
-
-dm-zoned exposes a logical device with a sector size of 4096 bytes,
-irrespective of the physical sector size of the backend zoned block
-device being used. This allows reducing the amount of metadata needed to
-manage valid blocks (blocks written).
-
-The on-disk metadata format is as follows:
-
-1) The first block of the first conventional zone found contains the
-super block which describes the on disk amount and position of metadata
-blocks.
-
-2) Following the super block, a set of blocks is used to describe the
-mapping of the logical device blocks. The mapping is done per chunk of
-blocks, with the chunk size equal to the zoned block device size. The
-mapping table is indexed by chunk number and each mapping entry
-indicates the zone number of the device storing the chunk of data. Each
-mapping entry may also indicate if the zone number of a conventional
-zone used to buffer random modification to the data zone.
-
-3) A set of blocks used to store bitmaps indicating the validity of
-blocks in the data zones follows the mapping table. A valid block is
-defined as a block that was written and not discarded. For a buffered
-data chunk, a block is always valid only in the data zone mapping the
-chunk or in the buffer zone of the chunk.
-
-For a logical chunk mapped to a conventional zone, all write operations
-are processed by directly writing to the zone. If the mapping zone is a
-sequential zone, the write operation is processed directly only if the
-write offset within the logical chunk is equal to the write pointer
-offset within of the sequential data zone (i.e. the write operation is
-aligned on the zone write pointer). Otherwise, write operations are
-processed indirectly using a buffer zone. In that case, an unused
-conventional zone is allocated and assigned to the chunk being
-accessed. Writing a block to the buffer zone of a chunk will
-automatically invalidate the same block in the sequential zone mapping
-the chunk. If all blocks of the sequential zone become invalid, the zone
-is freed and the chunk buffer zone becomes the primary zone mapping the
-chunk, resulting in native random write performance similar to a regular
-block device.
-
-Read operations are processed according to the block validity
-information provided by the bitmaps. Valid blocks are read either from
-the sequential zone mapping a chunk, or if the chunk is buffered, from
-the buffer zone assigned. If the accessed chunk has no mapping, or the
-accessed blocks are invalid, the read buffer is zeroed and the read
-operation terminated.
-
-After some time, the limited number of convnetional zones available may
-be exhausted (all used to map chunks or buffer sequential zones) and
-unaligned writes to unbuffered chunks become impossible. To avoid this
-situation, a reclaim process regularly scans used conventional zones and
-tries to reclaim the least recently used zones by copying the valid
-blocks of the buffer zone to a free sequential zone. Once the copy
-completes, the chunk mapping is updated to point to the sequential zone
-and the buffer zone freed for reuse.
-
-Metadata Protection
-===================
-
-To protect metadata against corruption in case of sudden power loss or
-system crash, 2 sets of metadata zones are used. One set, the primary
-set, is used as the main metadata region, while the secondary set is
-used as a staging area. Modified metadata is first written to the
-secondary set and validated by updating the super block in the secondary
-set, a generation counter is used to indicate that this set contains the
-newest metadata. Once this operation completes, in place of metadata
-block updates can be done in the primary metadata set. This ensures that
-one of the set is always consistent (all modifications committed or none
-at all). Flush operations are used as a commit point. Upon reception of
-a flush request, metadata modification activity is temporarily blocked
-(for both incoming BIO processing and reclaim process) and all dirty
-metadata blocks are staged and updated. Normal operation is then
-resumed. Flushing metadata thus only temporarily delays write and
-discard requests. Read requests can be processed concurrently while
-metadata flush is being executed.
-
-Usage
-=====
-
-A zoned block device must first be formatted using the dmzadm tool. This
-will analyze the device zone configuration, determine where to place the
-metadata sets on the device and initialize the metadata sets.
-
-Ex:
-
-dmzadm --format /dev/sdxx
-
-For a formatted device, the target can be created normally with the
-dmsetup utility. The only parameter that dm-zoned requires is the
-underlying zoned block device name. Ex:
-
-echo "0 `blockdev --getsize ${dev}` zoned ${dev}" | dmsetup create dmz-`basename ${dev}`
