From b101b68e2faf6a6065979d506d779c6606dec58f Mon Sep 17 00:00:00 2001 From: Joshua Colp Date: Fri, 27 Mar 2009 15:57:28 +0000 Subject: [PATCH] Fix a potential timer leak in bridge_softmix. It is possible for a bridge to be created without actually being used. In that scenario a timing file descriptor would be opened and not closed. To fix this the timing file descriptor is now closed in the destroy callback, not the thread function. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@184677 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- bridges/bridge_softmix.c | 13 +++++++++++-- 1 file changed, 11 insertions(+), 2 deletions(-) diff --git a/bridges/bridge_softmix.c b/bridges/bridge_softmix.c index 953dbb45af..8a8e94d836 100644 --- a/bridges/bridge_softmix.c +++ b/bridges/bridge_softmix.c @@ -96,6 +96,16 @@ static int softmix_bridge_create(struct ast_bridge *bridge) return 0; } +/*! \brief Function called when a bridge is destroyed */ +static int softmix_bridge_destroy(struct ast_bridge *bridge) +{ + int timingfd = (unsigned long)bridge->bridge_pvt; + + ast_timer_close(timingfd); + + return 0; +} + /*! \brief Function called when a channel is joined into the bridge */ static int softmix_bridge_join(struct ast_bridge *bridge, struct ast_bridge_channel *bridge_channel) { @@ -263,8 +273,6 @@ static int softmix_bridge_thread(struct ast_bridge *bridge) ao2_lock(bridge); } - ast_timer_close(timingfd); - return 0; } @@ -278,6 +286,7 @@ static struct ast_bridge_technology softmix_bridge = { .formats = AST_FORMAT_SLINEAR, #endif .create = softmix_bridge_create, + .destroy = softmix_bridge_destroy, .join = softmix_bridge_join, .leave = softmix_bridge_leave, .write = softmix_bridge_write,
