Since the 80's, I estimate around 5 algorithm changes, so any chosen seed is unrepeatable UB. +The deterministic sequence algorithm changed a number of times since +original development, is underspecified, and should not be relied upon to +remain consistent between platforms and over time. ok jmc kettenis Xr and Ox fixes; 2014-12-09T21:55:39+00:00 jmc 2014-12-09T21:55:39+00:00 urn:sha1:7b4389f21ce09e7d34ad8e9cedcf015c105d2bb1 Change rand(), random(), drand48(), lrand48(), mrand48(), and srand48() 2014-12-08T21:45:20+00:00 deraadt 2014-12-08T21:45:20+00:00 urn:sha1:9736a7f2a9e739ee9fc431040def5680fbb8794a 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 rand() is a pseudo-random number generator 2014-11-25T17:41:12+00:00 millert 2014-11-25T17:41:12+00:00 urn:sha1:ba34ec60686eb8f1dc15739220f1d1ea67d4dd7e it is 2014, and we still need to encourage people away from srand() 2014-07-17T23:12:28+00:00 deraadt 2014-07-17T23:12:28+00:00 urn:sha1:60721d2b6012c2aa79de24c38ab93b24f8a8d6ab and random().
