From bbeb5403be5330b145ad01ccdbfa305d3bf8a76d Mon Sep 17 00:00:00 2001 From: christos Date: Sun, 26 Jun 2011 16:42:39 +0000 Subject: * Arrange for interfaces that create new file descriptors to be able to set close-on-exec on creation (http://udrepper.livejournal.com/20407.html). - Add F_DUPFD_CLOEXEC to fcntl(2). - Add MSG_CMSG_CLOEXEC to recvmsg(2) for unix file descriptor passing. - Add dup3(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add pipe2(2) syscall with a flags argument for O_CLOEXEC, O_NONBLOCK. - Add flags SOCK_CLOEXEC, SOCK_NONBLOCK to the socket type parameter for socket(2) and socketpair(2). - Add new paccept(2) syscall that takes an additional sigset_t to alter the sigmask temporarily and a flags argument to set SOCK_CLOEXEC, SOCK_NONBLOCK. - Add new mode character 'e' to fopen(3) and popen(3) to open pipes and file descriptors for close on exec. - Add new kqueue1(2) syscall with a new flags argument to open the kqueue file descriptor with O_CLOEXEC, O_NONBLOCK. * Fix the system calls that take socklen_t arguments to actually do so. * Don't include userland header files (signal.h) from system header files (rump_syscallargs.h). * Bump libc version for the new syscalls. --- lib/libc/sys/socket.2 | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) (limited to 'lib/libc/sys/socket.2') diff --git a/lib/libc/sys/socket.2 b/lib/libc/sys/socket.2 index e13148b630d..f1966908900 100644 --- a/lib/libc/sys/socket.2 +++ b/lib/libc/sys/socket.2 @@ -1,4 +1,4 @@ -.\" $NetBSD: socket.2,v 1.36 2007/09/06 09:32:52 jnemeth Exp $ +.\" $NetBSD: socket.2,v 1.37 2011/06/26 16:42:41 christos Exp $ .\" .\" Copyright (c) 1983, 1991, 1993 .\" The Regents of the University of California.
