crypto: simd,testmgr - introduce crypto_simd_usable()

2019-03-22T12:57:27Z

So that the no-SIMD fallback code can be tested by the crypto self-tests, add a macro crypto_simd_usable() which wraps may_use_simd(), but also returns false if the crypto self-tests have set a per-CPU bool to disable SIMD in crypto code on the current CPU.

crypto: simd - support wrapping AEAD algorithms

2019-03-22T12:57:26Z

Update the crypto_simd module to support wrapping AEAD algorithms. Previously it only supported skciphers. The code for each is similar. I'll be converting the x86 implementations of AES-GCM, AEGIS, and MORUS to use this. Currently they each independently implement the same functionality. This will not only simplify the code, but it will also fix the bug detected by the improved self-tests: the user-provided aead_request is modified. This is because these algorithms currently reuse the original request, whereas the crypto_simd helpers build a new request in the original request's context.

crypto: user - forward declare crypto_nlsk

2019-01-18T10:43:43Z

Move the declaration of crypto_nlsk into internal/cryptouser.h. This fixes the following sparse warning: crypto/crypto_user_base.c:41:13: warning: symbol 'crypto_nlsk' was not declared. Should it be static? Cc: Corentin Labbe Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: algapi - remove crypto_alloc_instance()

2019-01-11T06:16:58Z

Now that all "blkcipher" templates have been converted to "skcipher", crypto_alloc_instance() is no longer used. And it's not useful any longer as it creates an old-style weakly typed instance rather than a new-style strongly typed instance. So remove it, and now that the name is freed up rename crypto_alloc_instance2() to crypto_alloc_instance(). Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: skcipher - add helper for simple block cipher modes

2019-01-11T06:16:57Z

The majority of skcipher templates (including both the existing ones and the ones remaining to be converted from the "blkcipher" API) just wrap a single block cipher algorithm. This includes cbc, cfb, ctr, ecb, kw, ofb, and pcbc. Add a helper function skcipher_alloc_instance_simple() that handles allocating an skcipher instance for this common case.

crypto: skcipher - remove remnants of internal IV generators

2018-12-23T03:52:45Z

Remove dead code related to internal IV generators, which are no longer used since they've been replaced with the "seqiv" and "echainiv" templates. The removed code includes: - The "givcipher" (GIVCIPHER) algorithm type. No algorithms are registered with this type anymore, so it's unneeded. - The "const char *geniv" member of aead_alg, ablkcipher_alg, and blkcipher_alg. A few algorithms still set this, but it isn't used anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG. Just hardcode "" or "" in those cases. - The 'skcipher_givcrypt_request' structure, which is never used. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: user - remove unused dump functions

2018-12-23T03:52:44Z

This patch removes unused dump functions for crypto_user_stats. There are remains of the copy/paste of crypto_user_base to crypto_user_stat and I forgot to remove them. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu

crypto: user - made crypto_user_stat optional

2018-12-07T06:15:00Z

Even if CRYPTO_STATS is set to n, some part of CRYPTO_STATS are compiled. This patch made all part of crypto_user_stat uncompiled in that case. Signed-off-by: Corentin Labbe Signed-off-by: Herbert Xu
