Remove unneeded sys/sysctl.h on linux.

2015-06-13T02:33:58+00:00

This only provides the sysctl wrapper in glibc, which we do not use and is not available in other libc implementations for Linux. Thanks to ncopa from github.

Not all Linux libc's include linux/sysctl.h in sys/sysctl.h.

2015-04-27T03:37:06+00:00

Include it if we have the sysctl syscall.

sys/sysctl.h includes linux/sysctl.h, remove the extra unchecked include

2015-03-22T13:28:03+00:00

include header needed by older linux kernels

2014-10-11T16:44:05+00:00

not all versions of include by default

preserve errno value on success.

2014-08-28T01:00:57+00:00

If getrandom returns a temporary failure, make sure errno is not polluted when it succeeds. Thanks to deraadt@ for pointing it out.

only build the getrandom path if SYS_getrandom is defined.

like the sysctl path

getrandom(2) support for getentropy_linux

2014-08-16T17:21:56+00:00

This enables support for the new getrandom(2) syscall in Linux 3.17. If the call exists and fails, return a failure in getentropy(2) emulation as well. This adds a EINTR check in case the urandom pool is not initialized. Tested on Fedora Rawhide with 3.17rc0 and Ubuntu 14.04 ok deraadt@

better match proposed syscall api

2014-07-22T01:15:58+00:00

protect sysctl path with SYS__sysctl instead; from enh@google, ok bcook
