From a1933bd1847951b959016f59ee744d1b18a00142 Mon Sep 17 00:00:00 2001 From: Laurent Bercot Date: Fri, 14 Oct 2016 17:07:56 +0000 Subject: Clean up and modernize librandom. Correct random number generation has historically been suprisingly painful to achieve. There was no standard, every system behaved in a subtly different way, and there were a few userland initiatives to get decent randomness, all incompatible of course. The situation is a bit better now, we're heading towards some standardization. The arc4random() series of functions is a good API, and available on a lot of systems - unfortunately not Linux, but on Linux the new getrandom() makes using /dev/random obsolete. So I removed the old crap in librandom, dropped EGD support, dropped dynamic backend selection, made a single API series (random_* instead of goodrandom_* and badrandom_*), added an arc4random backend and a getrandom backend, and defaulted to /dev/urandom backed up by SURF in the worst case. This should be much smaller and logical. However, it's a major API break, so the skarnet.org stack will be changed to adapt. --- src/librandom/unidevrandom.c | 38 -------------------------------------- 1 file changed, 38 deletions(-) delete mode 100644 src/librandom/unidevrandom.c (limited to 'src/librandom/unidevrandom.c') diff --git a/src/librandom/unidevrandom.c b/src/librandom/unidevrandom.c deleted file mode 100644 index fb7b6b8..0000000 --- a/src/librandom/unidevrandom.c +++ /dev/null @@ -1,38 +0,0 @@ -/* ISC license. */ - -#include -#include -#include - -#ifdef SKALIBS_HASDEVRANDOM - -#include "random-internal.h" - -int unidevrandom_init (union unirandominfo *u) -{ - return unirandomdev_sinit(u, "/dev/random") ; -} - -int unirandom_register_devrandom (unirandom *u) -{ - unirandom_register(u, &unidevrandom_init, &unirandomdev_finish, &unirandomdev_readb, &unirandomdev_readnb) ; - return 1 ; -} - -#else - -#include - -int unidevrandom_init (union unirandominfo *u) -{ - (void)u ; - return (errno = ENOSYS, 0) ; -} - -int unirandom_register_devrandom (unirandom *u) -{ - (void)u ; - return (errno = ENOSYS, 0) ; -} - -#endif -- cgit v1.2.3
