| * | crypto: chacha20 - use rol32() macro from bitops.h | Eric Biggers | 2018-01-12 | 1 | -37/+32 |
| | | | | | | | | | For chacha20_block(), use the existing 32-bit left-rotate function instead of defining one ourselves. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> | ||||
| * | crypto: chacha20 - Fix keystream alignment for chacha20_block() | Eric Biggers | 2017-11-29 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | When chacha20_block() outputs the keystream block, it uses 'u32' stores directly. However, the callers (crypto/chacha20_generic.c and drivers/char/random.c) declare the keystream buffer as a 'u8' array, which is not guaranteed to have the needed alignment. Fix it by having both callers declare the keystream as a 'u32' array. For now this is preferable to switching over to the unaligned access macros because chacha20_block() is only being used in cases where we can easily control the alignment (stack buffers).

| * | random: replace non-blocking pool with a Chacha20-based CRNG | Theodore Ts'o | 2016-07-03 | 1 | -0/+79 |
| The CRNG is faster, and we don't pretend to track entropy usage in the CRNG any more. Signed-off-by: Theodore Ts'o <tytso@mit.edu> | |||||
