Gregory Nutt	5129aeefd5	drivers/sensors: Fix remaining naming of configurations to be compliant for two more drivers.	2017-08-24 10:48:20 -06:00
Gregory Nutt	1f023fa31a	drivers/sensors: Fix more naming of configurations to be compliant for two more drivers. Still a few more to go.	2017-08-24 10:10:00 -06:00
Jussi Kivilinna	dffb8a67e3	Add entropy pool and strong random number generator ... Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output. Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively.	2017-03-30 07:38:37 -06:00
