* [PATCH 05/25] crypto: omap - switch to skcipher API [not found] <20191014121910.7264-1-ard.biesheuvel@linaro.org> @ 2019-10-14 12:18 ` Ard Biesheuvel 2019-10-15 17:28 ` Tony Lindgren 0 siblings, 1 reply; 7+ messages in thread From: Ard Biesheuvel @ 2019-10-14 12:18 UTC (permalink / raw) To: linux-crypto Cc: Herbert Xu, Eric Biggers, Tony Lindgren, Ard Biesheuvel, linux-omap, David S. Miller, linux-arm-kernel Commit 7a7ffe65c8c5 ("crypto: skcipher - Add top-level skcipher interface") dated 20 august 2015 introduced the new skcipher API which is supposed to replace both blkcipher and ablkcipher. While all consumers of the API have been converted long ago, some producers of the ablkcipher remain, forcing us to keep the ablkcipher support routines alive, along with the matching code to expose [a]blkciphers via the skcipher API. So switch this driver to the skcipher API, allowing us to finally drop the blkcipher code in the near future.

With this patch, I am seeing the SW fallback fail with the following crash. Any ideas why this happens? This on top of 5.4-rc2, I did not pick any other crypto patches from the lists, but have couple of local fixes to get AES working properly with latest changes to testmgr.

Thats right, it fixes it. There is another skcipher missing the ivsize within omap-aes.c it seems. Do you want to send a patch out for both or shall I send a patch with you as suggested by? I have some 10 omap crypto related patches on their way. -Tero > > diff --git a/drivers/crypto/omap-aes.c b/drivers/crypto/omap-aes.c > index 329fddbe8a39..a1fc03ed01f3 100644 > ---
