Hi, The following patch set contains random fixes to increase the efficiency of the DRBG. Changes include the removal of unneeded memset(0) and sanity checks. All changes do not weaken the implementation as only code is removed that is clearly covered by other code paths. In addition, the cpu_to_be kernel function together with a type cast is used to convert an integer into its string representation. This patch increases the speed of the DRBG by 10%. Stephan Mueller (8): DRBG: replace int2byte with cpu_to_be DRBG: kzfree does not need a check for NULL pointer DRBG: remove superflowous checks DRBG: remove superflowous memset(0) DRBG: use kmalloc instead of kzalloc for V and C DRBG: remove unnecessary sanity checks DRBG: remove configuration of fixed values DRBG: remove unnecessary sanity check for shadow state crypto/drbg.c | 130 ++++++++++++++++---------------------------------- include/crypto/drbg.h | 19 +++----- 2 files changed, 46 insertions(+), 103 deletions(-) -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
