[PATCH 00/30] crypto: reduce ahash API overhead

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series first removes the alignmask support from ahash.  As is
the case with shash, the alignmask support of ahash has no real point.
Removing it reduces API overhead and complexity.

Second, this patch series optimizes the common case where the ahash API
uses an shash algorithm, by eliminating unnecessary indirect calls.

This series can be retrieved from git at
https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git
tag "crypto-ahash-2023-10-22".  Note that it depends on my other series
"crypto: stop supporting alignmask in shash"
(https://lore.kernel.org/r/20231019055343.588846-1-ebiggers@xxxxxxxxxx).

Patch 1 cleans up after removal of alignmask support from shash.

Patches 2-12 make drivers stop setting an alignmask for ahashes.

Patch 13 removes alignmask support from ahash.

Patches 14-23 remove checks of ahash alignmasks that became unnecessary.

Patches 24-25 are other ahash related cleanups.

Patches 26-29 prepare for optimizing the ahash-using-shash case.

Patches 30 optimizes the ahash-using-shash case.
