Because the format of the protection data is tied to the physical disk, each block device has been extended with a block integrity profile (struct blk_integrity). This optional profile is registered with the block layer using blk_integrity_register().

End-to-end data consistency checking is based on a data integrity field (DIF) that is added to transferred data blocks. DIF data is used to confirm that a data block originates from the expected source and was not modified during the transfer between the storage system and the FCP device.

Jul 17, 2008 · Another post of my block I/O data integrity patches. This kit goes on top of the scsi_data_buffer and sd.h cleanups I posted earlier today. There has been no changes to the block layer code since my last submission. Within SCSI, the changes are cleanups based on comments from Christoph as well as working support for Type 3 and 4KB sectors.

APFS in Detail: Data Integrity. ... and most of the modern layer-5 protocols support retries, anyway. We put checksums in TCP because we see a lot of transmission errors in practice, and that’s a layer where the data integrity implementation can be shared by almost all applications. ... All these checksums generate additional data per block ...
