Brent Cook 0aeb93b9fc override native arc4random_buf on FreeBSD ... The FreeBSD-native arc4random_buf implementation falls back to weak sources of entropy if the sysctl fails. Remove these dangerous fallbacks by overriding locally. Unfortunately, pthread_atfork() is broken on FreeBSD (at least 9 and 10) if a program does not link to -lthr. Callbacks registered with pthread_atfork() simply fail silently. So, it is not always possible to detect a PID wraparound. I wish we could do better. This improves arc4random_buf's safety compared to the native FreeBSD implementation. Tested on FreeBSD 9 and 10. ok beck@ deraadt@		2014-11-03 01:19:36 -06:00
