crypto: add missing crypto module aliases

2015-02-04T10:57:50Z

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-"

2015-02-04T10:57:48Z

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 Signed-off-by: Herbert Xu [ luis: backported to 3.16: dropped changes to: - arch/arm/crypto/sha1_neon_glue.c - arch/arm/crypto/sha512_neon_glue.c - arch/x86/crypto/des3_ede_glue.c - drivers/crypto/qat/qat_common/adf_ctl_drv.c ] Signed-off-by: Luis Henriques

crypto: cleanup - remove unneeded crypto_alg.cra_list initializations

2012-08-01T09:47:27Z

Initialization of cra_list is currently mixed, most ciphers initialize this field and most shashes do not. Initialization however is not needed at all since cra_list is initialized/overwritten in __crypto_register_alg() with list_add(). Therefore perform cleanup to remove all unneeded initializations of this field in 'crypto/'. Signed-off-by: Jussi Kivilinna Signed-off-by: Herbert Xu

crypto: rng - RNG interface and implementation

2008-08-29T05:50:04Z

This patch adds a random number generator interface as well as a cryptographic pseudo-random number generator based on AES. It is meant to be used in cases where a deterministic CPRNG is required. One of the first applications will be as an input in the IPsec IV generation process. Signed-off-by: Neil Horman Signed-off-by: Herbert Xu
