crypto: sun8i-ce - handle endianness of t_common_ctl

2020-10-29T09:07:23Z

[ Upstream commit 87f34260f5e09a4578132ad1c05aef2d707dd4bf ] t_common_ctl is LE32 so we need to convert its value before using it. This value is only used on H6 (ignored on other SoCs) and not handling the endianness cause failure on xRNG/hashes operations on H6 when running BE.

docs: fix broken references for ReST files that moved around

2020-04-20T21:45:03Z

Some broken references happened due to shifting files around and ReST renames. Those can't be auto-fixed by the script, so let's fix them manually.

crypto: allwinner - remove redundant platform_get_irq error message

2020-02-13T09:05:26Z

Function dev_err() after platform_get_irq() is redundant because platform_get_irq() already prints an error. Signed-off-by: Chen Zhou Signed-off-by: Herbert Xu

crypto: sun8i-ce - fix removal of module

Removing the driver cause an oops due to the fact we clean an extra channel. Let's give the right index to the cleaning function. Fixes: 06f751b61329 ("crypto: allwinner - Add sun8i-ce Crypto Engine") Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: remove CRYPTO_TFM_RES_BAD_KEY_LEN

2020-01-09T03:30:53Z

The CRYPTO_TFM_RES_BAD_KEY_LEN flag was apparently meant as a way to make the ->setkey() functions provide more information about errors. However, no one actually checks for this flag, which makes it pointless. Also, many algorithms fail to set this flag when given a bad length key. Reviewing just the generic implementations, this is the case for aes-fixed-time, cbcmac, echainiv, nhpoly1305, pcrypt, rfc3686, rfc4309, rfc7539, rfc7539esp, salsa20, seqiv, and xcbc. But there are probably many more in arch/*/crypto/ and drivers/crypto/. Some algorithms can even set this flag when the key is the correct length. For example, authenc and authencesn set it when the key payload is malformed in any way (not just a bad length), the atmel-sha and ccree drivers can set it if a memory allocation fails, and the chelsio driver sets it for bad auth tag lengths, not just bad key lengths. So even if someone actually wanted to start checking this flag (which seems unlikely, since it's been unused for a long time), there would be a lot of work needed to get it working correctly. But it would probably be much better to go back to the drawing board and just define different return values, like -EINVAL if the key is invalid for the algorithm vs. -EKEYREJECTED if the key was rejected by a policy like "no weak keys". That would be much simpler, less error-prone, and easier to test. So just remove this flag. Signed-off-by: Eric Biggers Reviewed-by: Horia Geantă Signed-off-by: Herbert Xu

crypto: sun8i-ce - enable working on big endian

2019-11-22T10:48:38Z

On big endian kernel, the sun8i-ce crypto driver does not works.
