Merge tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random

2016-07-27T22:11:55Z

Pull random driver updates from Ted Ts'o: "A number of improvements for the /dev/random driver; the most important is the use of a ChaCha20-based CRNG for /dev/urandom, which is faster, more efficient, and easier to make scalable for silly/abusive userspace programs that want to read from /dev/urandom in a tight loop on NUMA systems. This set of patches also improves entropy gathering on VM's running on Microsoft Azure, and will take advantage of a hw random number generator (if present) to initialize the /dev/urandom pool" (It turns out that the random tree hadn't been in linux-next this time around, because it had been dropped earlier as being too quiet. Oh well). * tag 'random_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random: random: strengthen input validation for RNDADDTOENTCNT random: add backtracking protection to the CRNG random: make /dev/urandom scalable for silly userspace programs random: replace non-blocking pool with a Chacha20-based CRNG random: properly align get_random_int_hash random: add interrupt callback to VMBus IRQ handler random: print a warning for the first ten uninitialized random users random: initialize the non-blocking pool via add_hwgenerator_randomness()

crypto: skcipher - Add comment for skcipher_alg->base

2016-07-19T07:42:42Z

This patch adds a missing comment for the base parameter in struct skcipher_alg. Reported-by: kbuild test robot Signed-off-by: Herbert Xu

crypto: scatterwalk - Inline start/map/done

2016-07-18T09:35:50Z

This patch inlines the functions scatterwalk_start, scatterwalk_map and scatterwalk_done as they're all tiny and mostly used by the block cipher walker. Signed-off-by: Herbert Xu

crypto: api - Optimise away crypto_yield when hard preemption is on

2016-07-18T09:35:49Z

When hard preemption is enabled there is no need to explicitly call crypto_yield. This patch eliminates it if that is the case. Signed-off-by: Herbert Xu

crypto: scatterwalk - Remove scatterwalk_bytes_sglen

2016-07-18T09:35:48Z

This patch removes the now unused scatterwalk_bytes_sglen. Anyone using this out-of-tree should switch over to sg_nents_for_len. Signed-off-by: Herbert Xu

crypto: skcipher - Remove top-level givcipher interface

2016-07-18T09:35:46Z

This patch removes the old crypto_grab_skcipher helper and replaces it with crypto_grab_skcipher2. As this is the final entry point into givcipher this patch also removes all traces of the top-level givcipher interface, including all implicit IV generators such as chainiv. The bottom-level givcipher interface remains until the drivers using it are converted. Signed-off-by: Herbert Xu

crypto: null - Remove default null blkcipher

2016-07-18T09:35:44Z

The default null blkcipher is no longer used and can now be removed. Signed-off-by: Herbert Xu

crypto: aead - Remove blkcipher null for IV generators

2016-07-18T09:35:43Z

The blkcipher null object is no longer used and can now be removed. Signed-off-by: Herbert Xu

crypto: aead - Add skcipher null for IV generators

2016-07-18T09:35:42Z

This patch adds an skcipher null object alongside the existing null blkcipher so that IV generators using it can switch over to skcipher. Signed-off-by: Herbert Xu

crypto: aead - Add chunk size

2016-07-18T09:35:38Z

This patch adds a chunk size parameter to aead algorithms, just like the chunk size for skcipher algorithms. However, unlike skcipher we do not currently export this to AEAD users. It is only meant to be used by AEAD implementors for now. Signed-off-by: Herbert Xu
