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/unirandomegd.c | 37 ------------------------------------- 1 file changed, 37 deletions(-) delete mode 100644 src/librandom/unirandomegd.c (limited to 'src/librandom/unirandomegd.c') diff --git a/src/librandom/unirandomegd.c b/src/librandom/unirandomegd.c deleted file mode 100644 index a340f06..0000000 --- a/src/librandom/unirandomegd.c +++ /dev/null @@ -1,37 +0,0 @@ -/* ISC license. */ - -#include -#include -#include -#include -#include - -int unirandomegd_sinit (union unirandominfo *u, char const *path) -{ - register int s = randomegd_open(path) ; - if (s == -1) return 0 ; - if (coe(s) == -1) - { - register int e = errno ; - fd_close(s) ; - errno = e ; - return 0 ; - } - u->egd.fd = s ; - return 1 ; -} - -int unirandomegd_finish (union unirandominfo *u) -{ - return !fd_close(u->egd.fd) ; -} - -unsigned int unirandomegd_readb (union unirandominfo *u, char *s, unsigned int n) -{ - return randomegd_readb(u->egd.fd, s, n) ; -} - -unsigned int unirandomegd_readnb (union unirandominfo *u, char *s, unsigned int n) -{ - return randomegd_readnb(u->egd.fd, s, n) ; -} -- cgit v1.2.3
