These are the same as the FreeBSD shims. ok deraadt@ back in september I did the large abstraction refactoring to allow these 2015-01-15T06:57:18+00:00 deraadt 2015-01-15T06:57:18+00:00 urn:sha1:2c0fa7a33267776e90c29aa1b640595e92c0d8f7 other systems to fit into the same mold, so add copyright mix in more virtual memory and process information 2015-01-07T01:15:57+00:00 bcook 2015-01-07T01:15:57+00:00 urn:sha1:84d3a443bfbb7a97be016bcdc5e73d244c6987ad add initial HP-UX getentropy/arc4random support. 2015-01-06T21:08:11+00:00 bcook 2015-01-06T21:08:11+00:00 urn:sha1:0facf1dc285a76d9848d5c48673c3b02ce1dec91 patch from Kinichiro Inoguchi, tested on HP-UX 11.31 ok deraadt@ correct the failure case for getentropy on win32 2014-11-11T13:54:33+00:00 bcook 2014-11-11T13:54:33+00:00 urn:sha1:8d5f6fbe06d6b13dd764a076a1f541134df3c108 CryptAcquireContext and CryptGenRandom returns zero (FALSE) if fails. From: Dongsheng Song <dongsheng.song@gmail.com> Add hooks to override native arc4random_buf on FreeBSD. 2014-11-03T06:23:30+00:00 bcook 2014-11-03T06:23:30+00:00 urn:sha1:97f48e5c1a29dd52ce16c023eaa14f5da0110610 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 also 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.
