crypto: ghash-generic - move common definitions to a new header file

2016-10-22T10:40:25+00:00

commit a397ba829d7f8aff4c90af3704573a28ccd61a59 upstream.

Move common values and types used by ghash-generic to a new header file
so drivers can directly use ghash-generic as a fallback implementation.

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

2016-07-27T22:11:55+00:00

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: scatterwalk - Inline start/map/done

2016-07-18T09:35:50+00:00

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.

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

2016-07-18T09:35:49+00:00

When hard preemption is enabled there is no need to explicitly
call crypto_yield.  This patch eliminates it if that is the case.

crypto: scatterwalk - Remove scatterwalk_bytes_sglen

2016-07-18T09:35:48+00:00

This patch removes the now unused scatterwalk_bytes_sglen.  Anyone
using this out-of-tree should switch over to sg_nents_for_len.

crypto: skcipher - Remove top-level givcipher interface

2016-07-18T09:35:46+00:00

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.

crypto: aead - Add skcipher null for IV generators

2016-07-18T09:35:42+00:00

This patch adds an skcipher null object alongside the existing
null blkcipher so that IV generators using it can switch over
to skcipher.
