New submission from STINNER Victor: The future OpenBSD 5.6 (scheduled in november 2014) will have a new getentropy() syscall and a new getentropy() in their C library which avoid the need of a file descriptor: http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD-current/man2/getentropy.2?query=getentropy&sec=2
Note: "The maximum buffer size permitted is 256 bytes. If buflen exceeds this, an error of EIO will be indicated." The file descriptor of os.urandom() causes perfomance issues and surprising bugs: #18756, #21207. For Python 2.7, see also the PEP 466 and the issue #21305. See also issues: - #22181: os.urandom() should use Linux 3.17 getrandom() syscall - #22542: Use arc4random under OpenBSD for os.urandom() if /dev/urandom is not present ---------- messages: 228846 nosy: haypo priority: normal severity: normal status: open title: os.urandom() should use getentropy() of OpenBSD 5.6 type: security versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22585> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
