From b84886ba3e362f54b70aefcbe1aa10606309b7d7 Mon Sep 17 00:00:00 2001 From: Damien Miller Date: Mon, 19 May 2008 15:05:07 +1000 Subject: - djm@cvs.openbsd.org 2008/05/08 12:02:23 [auth-options.c auth1.c channels.c channels.h clientloop.c gss-serv.c] [monitor.c monitor_wrap.c nchan.c servconf.c serverloop.c session.c] [ssh.c sshd.c] Implement a channel success/failure status confirmation callback mechanism. Each channel maintains a queue of callbacks, which will be drained in order (RFC4253 guarantees confirm messages are not reordered within an channel). Also includes a abandonment callback to clean up if a channel is closed without sending confirmation messages. This probably shouldn't happen in compliant implementations, but it could be abused to leak memory. ok markus@ (as part of a larger diff) --- serverloop.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'serverloop.c') diff --git a/serverloop.c b/serverloop.c index bf3f9c9f..20991c3c 100644 --- a/serverloop.c +++ b/serverloop.c @@ -1,4 +1,4 @@ -/* $OpenBSD: serverloop.c,v 1.148 2008/02/22 20:44:02 dtucker Exp $ */ +/* $OpenBSD: serverloop.c,v 1.149 2008/05/08 12:02:23 djm Exp $ */ /* * Author: Tatu Ylonen * Copyright (c) 1995 Tatu Ylonen , Espoo, Finland @@ -56,6 +56,7 @@ #include #include +#include "openbsd-compat/sys-queue.h" #include "xmalloc.h" #include "packet.h" #include "buffer.h" @@ -1188,8 +1189,9 @@ server_init_dispatch_20(void) dispatch_set(SSH2_MSG_CHANNEL_REQUEST, &server_input_channel_req); dispatch_set(SSH2_MSG_CHANNEL_WINDOW_ADJUST, &channel_input_window_adjust); dispatch_set(SSH2_MSG_GLOBAL_REQUEST, &server_input_global_request); + dispatch_set(SSH2_MSG_CHANNEL_SUCCESS, &channel_input_status_confirm); + dispatch_set(SSH2_MSG_CHANNEL_FAILURE, &channel_input_status_confirm); /* client_alive */ - dispatch_set(SSH2_MSG_CHANNEL_FAILURE, &server_input_keep_alive); dispatch_set(SSH2_MSG_REQUEST_SUCCESS, &server_input_keep_alive); dispatch_set(SSH2_MSG_REQUEST_FAILURE, &server_input_keep_alive); /* rekeying */ -- cgit v1.2.1
