crypto: talitos - HMAC SNOOP NO AFEU mode requires SW icv checking.

2019-09-19T07:11:05+00:00

commit 4bbfb839259a9c96a0be872e16f7471b7136aee5 upstream. In that mode, hardware ICV verification is not supported. Signed-off-by: Christophe Leroy Fixes: 7405c8d7ff97 ("crypto: talitos - templates for AEAD using HMAC_SNOOP_NO_AFEU") Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: talitos - Do not modify req->cryptlen on decryption.

2019-09-19T07:11:05+00:00

commit 7ede4c36cf7c6516986ee9d75b197c8bf73ea96f upstream. For decrypt, req->cryptlen includes the size of the authentication part while all functions of the driver expect cryptlen to be the size of the encrypted data. As it is not expected to change req->cryptlen, this patch implements local calculation of cryptlen.

crypto: talitos - fix ECB algs ivsize

commit d84cc9c9524ec5973a337533e6d8ccd3e5f05f2b upstream. ECB's ivsize must be 0. Signed-off-by: Christophe Leroy Fixes: 5e75ae1b3cef ("crypto: talitos - add new crypto modes") Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: talitos - check data blocksize in ablkcipher.

2019-09-19T07:11:04+00:00

commit ee483d32ee1a1a7f7d7e918fbc350c790a5af64a upstream. When data size is not a multiple of the alg's block size, the SEC generates an error interrupt and dumps the registers. And for NULL size, the SEC does just nothing and the interrupt is awaited forever. This patch ensures the data size is correct before submitting the request to the SEC engine.

crypto: talitos - fix CTR alg blocksize

2019-09-19T07:11:04+00:00

commit b9a05b6041cb9810a291315569b2af0d63c3680a upstream. CTR has a blocksize of 1. Signed-off-by: Christophe Leroy Fixes: 5e75ae1b3cef ("crypto: talitos - add new crypto modes") Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: talitos - check AES key size

2019-09-19T07:11:04+00:00

commit 1ba34e71e9e56ac29a52e0d42b6290f3dc5bfd90 upstream. Although the HW accepts any size and silently truncates it to the correct length, the extra tests expects EINVAL to be returned when the key size is not valid.

crypto: ccp - Ignore unconfigured CCP device on suspend/resume

2019-09-06T08:23:47+00:00

commit 5871cd93692c8071fb9358daccb715b5081316ac upstream. If a CCP is unconfigured (e.g. there are no available queues) then there will be no data structures allocated for the device. Thus, we must check for validity of a pointer before trying to access structure members.

crypto: ccp - Ignore tag length when decrypting GCM ciphertext

2019-08-16T08:10:51+00:00

commit e2664ecbb2f26225ac6646876f2899558ffb2604 upstream. AES GCM input buffers for decryption contain AAD+CTEXT+TAG. Only decrypt the ciphertext, and use the tag for comparison.

crypto: ccp - Add support for valid authsize values less than 16

2019-08-16T08:10:51+00:00

commit 9f00baf74e4b6f79a3a3dfab44fb7bb2e797b551 upstream. AES GCM encryption allows for authsize values of 4, 8, and 12-16 bytes. Validate the requested authsize, and retain it to save in the request context.

crypto: ccp - Fix oops by properly managing allocated structures

2019-08-16T08:10:51+00:00

commit 25e44338321af545ab34243a6081c3f0fc6107d0 upstream. A plaintext or ciphertext length of 0 is allowed in AES, in which case no encryption occurs. Ensure that we don't clean up data structures that were never allocated.
