If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 87a7f98e76b745088a60494313104241ccd22fdb Author: Horia Geantă <horia.geanta@xxxxxxx> Date: Fri Oct 15 10:39:18 2021 +0300 crypto: tcrypt - fix skcipher multi-buffer tests for 1420B blocks [ Upstream commit 3ae88f676aa63366ffa9eebb8ae787c7e19f0c57 ] Commit ad6d66bcac77e ("crypto: tcrypt - include 1420 byte blocks in aead and skcipher benchmarks") mentions: > power-of-2 block size. So let's add 1420 bytes explicitly, and round > it up to the next blocksize multiple of the algo in question if it > does not support 1420 byte blocks. but misses updating skcipher multi-buffer tests. Fix this by using the proper (rounded) input size.
