crypto: mcryptd - Check mcryptd algorithm compatibility

2016-12-07T11:55:37Z

Algorithms not compatible with mcryptd could be spawned by mcryptd with a direct crypto_alloc_tfm invocation using a "mcryptd(alg)" name construct. This causes mcryptd to crash the kernel if an arbitrary "alg" is incompatible and not intended to be used with mcryptd. It is an issue if AF_ALG tries to spawn mcryptd(alg) to expose it externally. But such algorithms must be used internally and not be exposed. We added a check to enforce that only internal algorithms are allowed with mcryptd at the time mcryptd is spawning an algorithm.

crypto: sha1-mb - async implementation for sha1-mb

2016-06-23T10:29:55Z

Herbert wants the sha1-mb algorithm to have an async implementation: https://lkml.org/lkml/2016/4/5/286. Currently, sha1-mb uses an async interface for the outer algorithm and a sync interface for the inner algorithm. This patch introduces a async interface for even the inner algorithm.

crypto: mcryptd - Fix load failure

2016-01-30T14:11:20Z

mcryptd_create_hash() fails by returning -EINVAL, causing any driver using mcryptd to fail to load. It is because it needs to set its statesize properly. Signed-off-by: Rui Wang Signed-off-by: Herbert Xu

crypto: mcryptd - process CRYPTO_ALG_INTERNAL

2015-03-31T13:21:13Z

The mcryptd is used as a wrapper around internal ciphers. Therefore, the mcryptd must process the internal cipher by marking mcryptd as internal if the underlying cipher is an internal cipher. Signed-off-by: Stephan Mueller Signed-off-by: Herbert Xu

crypto: include crypto- module prefix in template

2014-11-26T12:06:30Z

This adds the module loading prefix "crypto-" to the template lookup as well. For example, attempting to load 'vfat(blowfish)' via AF_ALG now correctly includes the "crypto-" prefix at every level, correctly rejecting "vfat": net-pf-38 algif-hash crypto-vfat(blowfish) crypto-vfat(blowfish)-all crypto-vfat Reported-by: Mathias Krause Signed-off-by: Kees Cook Acked-by: Mathias Krause Signed-off-by: Herbert Xu

crypto: sha-mb - multibuffer crypto infrastructure

2014-08-25T12:32:25Z

This patch introduces the multi-buffer crypto daemon which is responsible for submitting crypto jobs in a work queue to the responsible multi-buffer crypto algorithm. The idea of the multi-buffer algorihtm is to put data streams from multiple jobs in a wide (AVX2) register and then take advantage of SIMD instructions to do crypto computation on several buffers simultaneously. The multi-buffer crypto daemon is also responsbile for flushing the remaining buffers to complete the computation if no new buffers arrive for a while.
