| | | | | It may take a few iterations to get the tone right. previously discussed with millert
* Change rand(), random(), drand48(), lrand48(), mrand48(), and srand48()deraadt2014-12-081-35/+14
| | | | | | | | | | | | | | | | | to returning strong random by default, source from arc4random(3). Parameters to the seeding functions are ignored, and the subsystems remain in strong random mode. If you wish the standardized deterministic mode, call srand_deterministic(), srandom_determistic(), srand48_deterministic(), seed48_deterministic() or lcong48_deterministic() instead. The re-entrant functions rand_r(), erand48(), nrand48(), jrand48() are unaffected by this change and remain in deterministic mode (for now). Verified as a good roadmap forward by auditing 8800 pieces of software. Roughly 60 pieces of software will need adaptation to request the deterministic mode. Violates POSIX and C89, which violate best practice in this century. ok guenther tedu millert

* Fix a bug where random() always returns 0 when srandom() is seededmillert2012-03-211-2/+3

* Use sysctl(KERN_ARND) to get n bytes, instead of just 4 at a timeotto2005-11-301-38/+11
| | | | | | | and remove fallback code. If somebody is dumb enough to make the sysctl fail using systrace, he deserves what he gets. Saves 7 syscalls on process startup. looks good miod@ ok deraadt@ tedu@

* Use int32_t, not long since this deals with 32bit quantities.millert2003-02-281-20/+20
| | | | Inspired by a change in NetBSD and reported by Jan Johansson.
* In srandomdev(), if we can't access /dev/arandom, use the sysctl() instead.millert2002-12-061-10/+27
| | | | | We don't want to use the sysctl() by default since we are reading more than just a few bytes of entropy when setting up the state.
