• 10081fb53   lib: introduce crc_t10dif_update() ... Browse Code »

  This introduces crc_t10dif_update() which enables to calculate CRC
  for a block which straddles multiple SG elements by calling multiple
  times. This also converts crc_t10dif() to use crc_t10dif_update() as
  they are almost same.

  (remove extra function call in crc_t10dif() and crc_t10dif_update -

• 26052f9b9   crypto: crct10dif - Add fallback for broken initrds ... Browse Code »

  Unfortunately, even with a softdep some distros fail to include
  the necessary modules in the initrd. Therefore this patch adds
  a fallback path to restore existing behaviour where we cannot
  load the new crypto crct10dif algorithm.

  In order to do this, the underlying crct10dif has been split out
  from the crypto implementation so that it can be used on the
  fallback path.

  Now that module softdeps are in the kernel we can use that to resolve
  the boot issue which cause the revert.

  Unfortunately this change broke boot on some systems that used an
  initrd which does not include the newly created crct10dif modules.
  As these modules are required by sd_mod under certain configurations
  this is a serious problem.

  When CRC T10 DIF is calculated using the crypto transform framework, we
  wrap the crc_t10dif function call to utilize it. This allows us to
  take advantage of any accelerated CRC T10 DIF transform that is
  plugged into the crypto framework.

  The SCSI Block Protocol uses this 16-bit CRC to verify the integrity
  of each data sector. crc_t10dif() is used by sd_dif.c when performing
  I/O to or from disks formatted with protection information.
