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/libunixonacid/atomic_rm_rf_tmp.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/libunixonacid/atomic_rm_rf_tmp.c') diff --git a/src/libunixonacid/atomic_rm_rf_tmp.c b/src/libunixonacid/atomic_rm_rf_tmp.c index 8be5189..5bba785 100644 --- a/src/libunixonacid/atomic_rm_rf_tmp.c +++ b/src/libunixonacid/atomic_rm_rf_tmp.c @@ -16,7 +16,7 @@ int atomic_rm_rf_tmp (char const *filename, stralloc *tmp) start = tmp->len ; for (;;) { - if (random_sauniquename(tmp, 64) < 0) goto err ; + if (!random_sauniquename(tmp, 64)) goto err ; if (!stralloc_0(tmp)) goto err ; if (!rename(filename, tmp->s + tmpbase)) break ; if (errno != EEXIST && errno != ENOTEMPTY) goto err ; -- cgit v1.2.3
