From e241e85ad3fd50fb94666ddaa52e44cbaae47fbb Mon Sep 17 00:00:00 2001 From: Damien Miller Date: Thu, 27 Mar 2008 11:01:15 +1100 Subject: - deraadt@cvs.openbsd.org 2008/03/24 16:11:07 [monitor_fdpass.c] msg_controllen has to be CMSG_SPACE so that the kernel can account for each cmsg_len (ie. msg_controllen = sum of CMSG_ALIGN(cmsg_len). This works now that kernel fd passing has been fixed to accept a bit of sloppiness because of this ABI repair. lots of discussion with kettenis --- monitor_fdpass.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'monitor_fdpass.c') diff --git a/monitor_fdpass.c b/monitor_fdpass.c index 18ae6248a..cab538bc9 100644 --- a/monitor_fdpass.c +++ b/monitor_fdpass.c @@ -1,4 +1,4 @@ -/* $OpenBSD: monitor_fdpass.c,v 1.16 2008/03/15 16:19:02 deraadt Exp $ */ +/* $OpenBSD: monitor_fdpass.c,v 1.17 2008/03/24 16:11:07 deraadt Exp $ */ /* * Copyright 2001 Niels Provos * All rights reserved. @@ -63,7 +63,7 @@ mm_send_fd(int sock, int fd) msg.msg_accrightslen = sizeof(fd); #else msg.msg_control = (caddr_t)&cmsgbuf.buf; - msg.msg_controllen = CMSG_LEN(sizeof(int)); + msg.msg_controllen = sizeof(cmsgbuf.buf); cmsg = CMSG_FIRSTHDR(&msg); cmsg->cmsg_len = CMSG_LEN(sizeof(int)); cmsg->cmsg_level = SOL_SOCKET; @@ -121,7 +121,7 @@ mm_receive_fd(int sock) msg.msg_accrightslen = sizeof(fd); #else msg.msg_control = &cmsgbuf.buf; - msg.msg_controllen = CMSG_LEN(sizeof(int)); + msg.msg_controllen = sizeof(cmsgbuf.buf); #endif if ((n = recvmsg(sock, &msg, 0)) == -1) { -- cgit v1.2.3
