hwrng: Pass entropy to add_hwgenerator_randomness() in bits, not bytes
(2014-08-05 16:50:10 -0400)
----------------------------------------------------------------
Cleanups and bug fixes to /dev/random, add a new getrandom(2) system
call, which is a superset of OpenBSD's getentropy(2) call, for use
with userspace crypto libraries such as LibreSSL. Also add the
ability to have a kernel thread to pull entropy from hardware rng
devices into /dev/random.
----------------------------------------------------------------
Stephen Boyd (1):
hwrng: Pass entropy to add_hwgenerator_randomness() in bits, not bytes
Theodore Ts'o (8):
random: always update the entropy pool under the spinlock
random: remove unneeded hash of a portion of the entropy pool
random: only update the last_pulled time if we actually transferred
entropy
random: clean up interrupt entropy accounting for archs w/o cycle counters
random: use an improved fast_mix() function
random: use registers from interrupted code for CPU's w/o a cycle counter
random: introduce getrandom(2) system call
random: limit the contribution of the hw rng to at most half
Torsten Duwe (4):
random: add_hwgenerator_randomness() for feeding entropy from devices
hwrng: create filler thread
hwrng: add per-device entropy derating
hw_random: fix sparse warning (NULL vs 0 for pointer)
