* crypto: add missing crypto module aliasesMathias Krause2015-02-201-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 3e14dcf7cb80b34a1f38b55bc96f02d23fdaaaaf upstream. Commit 5d26a105b5a7 ("crypto: prefix module autoloading with "crypto-"") changed the automatic module loading when requesting crypto algorithms to prefix all module requests with "crypto-". This requires all crypto modules to have a crypto specific module alias even if their file name would otherwise match the requested crypto algorithm. Even though commit 5d26a105b5a7 added those aliases for a vast amount of modules, it was missing a few. Add the required MODULE_ALIAS_CRYPTO annotations to those files to make them get loaded automatically, again. This fixes, e.g., requesting 'ecb(blowfish-generic)', which used to work with kernels v3.18 and below. Also change MODULE_ALIAS() lines to MODULE_ALIAS_CRYPTO(). The former won't work for crypto modules any more.

* crypto: prefix module autoloading with "crypto-"Kees Cook2015-02-201-2/+2
| | | | | | | | | | | | | | | | | | commit 5d26a105b5a73e5635eae0629b42fa0a90e07b7b upstream. This prefixes all crypto module loading with "crypto-" so we never run the risk of exposing module auto-loading to userspace via a crypto API, as demonstrated by Mathias Krause: https://lkml.org/lkml/2013/3/4/70 Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> [bwh: Backported to 3.2: - Adjust filenames - Drop changes to algorithms and drivers we don't have - Add aliases to generic C implementations that didn't need them before] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
* crypto: sha256_generic - Add export/import supportHerbert Xu2009-07-111-12/+25
| | | | | | | | This patch adds export/import support to sha256_generic. The exported type is defined by struct sha256_state, which is basically the entire descriptor state of sha256_generic. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: sha256_generic - Use 64-bit counter like sha1Herbert Xu2009-07-111-35/+30
| | | | | | | This patch replaces the two 32-bit counter code in sha256_generic with the simpler 64-bit counter code from sha1. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Thanks for the suggestion, the init() is replaced with <algorithm name>_mod_init () and fini () is replaced with <algorithm name>_mod_fini.

* [CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224Jonathan Lynch2008-01-111-8/+64
| | | | | | | | | | | | | | | | | Resubmitting this patch which extends sha256_generic.c to support SHA-224 as described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

* cleanup asm/scatterlist.h includesAdrian Bunk2007-11-021-1/+0
| | | | | | | | | | | Not architecture specific code should not #include <asm/scatterlist.h>.

* [CRYPTO] sha: Add header file for SHA definitionsJan Glauber2007-10-101-21/+10

* [CRYPTO] sha: Load the SHA[1|256] module by an aliasSebastian Siewior2007-10-101-0/+342
Loading the crypto algorithm by the alias instead of by module directly has the advantage that all possible implementations of this algorithm are loaded automatically and the crypto API can choose the best one depending on its priority. Additionally it ensures that the generic implementation as well as the HW driver (if available) is loaded in case the HW driver needs the generic version as fallback in corner cases. Also remove the probe for sha1 in padlock's init code. Quote from Herbert: The probe is actually pointless since we can always probe when the algorithm is actually used which does not lead to dead-locks like this.
