Attached patch adds os.getrandom(): thin wrapper on the Linux getrandom() syscall. os.getrandom() can return less bytes than requested. The patch is incomplete: it doesn't include documentation. I chose to not implement a loop to not loose entropy if a following call fails (ex: fail with EINTR). Rationale: https://mail.python.org/pipermail/security-sig/2016-July/000072.html We should also add Solaris support later. See also #27776: "PEP 524: Make os.urandom() blocking on Linux".
