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
Jussi Kivilinna	d0c54039dc	Add ffsl(), ffsll(), fls(), flsl(), flsll() and use GCC's __builtin_ctz/__builtin_clz for faster implementation of these	2017-03-24 09:41:31 -06:00
Gregory Nutt	05a288f2e1	C library: Add strerror_r	2017-03-08 12:14:07 -06:00
Gregory Nutt	4f5879f998	C library: Add ffs(). Add strings.h. Move strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are legacy functions; the contemporary counterparts should be used instead.	2017-02-16 16:10:09 -06:00

patacongo	5cb8226727	OK.. I think the directory has been recovered and renamed ... git-svn-id: svn://svn.code.sf.net/p/nuttx/code/trunk@5331 42af7a65-404d-4744-a932-0658087f49c3	2012-11-10 16:34:46 +00:00
patacongo	42997ede83	Still trying to recover directory contents ... git-svn-id: svn://svn.code.sf.net/p/nuttx/code/trunk@5330 42af7a65-404d-4744-a932-0658087f49c3	2012-11-10 16:19:12 +00:00
