2014-03-05bridge_native_rtp: Fix crash involving masqueradeKinsey Moore
It is possible for a channel to be masqueraded out of a bridge which means it may no longer have RTP glue to check upon leaving said bridge. If this situation occurred (it's possible at least during dial and call pickup) then Asterisk would crash. This change makes sure the glue is checked before use.

2013-12-13bridge_native_rtp: Deadlock during 4-way conference creationKevin Harwell
The change contains a slightly adjusted patch that was on the issue (submitted by kmoore). A fix was made by adding in a bridge lock while calling bridge_start/stop from the framehook callback. Since the framehook callback is not called from the bridging core the bridge is not locked, but needs to be before calling bridge_start.

2013-10-29bridge_native_rtp: Ensure bridge is torn downKinsey Moore
When a bridge transitions away from one tech to another, the tech going away is provided a dummy bridge with no channels in it to tear down. Currently this means that the teardown code exits prematurely and does not tear anything down. This change tears down RTP bridging for the channel provided in the leave bridge tech callback. This also reverts the majority of r400403 since it is now redundant.

2013-10-03Fix assumption in bridge_native_rtp.c regarding number of participants in a ↵Mark Michelson
bridge. When a party leaves a bridge, there may be more participants in the bridge than expected. As such, it is important not to make assumptions regarding the list of channels in a bridge. This change makes it so that when a party leaves a native RTP bridge, we unbridge it and the party it was bridged with. Previously, the first and last channels in the list were unbridged since it was assumed that these were the two channels that had been bridged. As previously stated, a new party had been inserted into the bridge, so this logic did not work properly.

2013-10-03Cache string values of formats on ast_format_cap() to save processing.Mark Michelson
Channel snapshots have string representations of the channel's native formats. Prior to this change, the format strings were re-created on ever channel snapshot creation. Since channel native formats rarely change, this was very wasteful. Now, string representations of formats may optionally be stored on the ast_format_cap for cases where string representations may be requested frequently. When formats are altered, the string cache is marked as invalid. When strings are requested, the cache validity is checked. If the cache is valid, then the cached strings are copied. If the cache is invalid, then the string cache is rebuilt and copied, and the cache is marked as being valid again. Review: https://reviewboard.asterisk.org/r/2879 ........

2013-09-27Fix refleaks of ast_rtp_instance structures.Mark Michelson
These refleaks were causing bridged calls not to close their RTP ports. Thus a call would leave open 4 ports (RTP for party A, RTCP for party A, RTP for party B, and RTCP for party B). This led to an eventual depletion of available RTP ports. ........

2013-08-23bridge_native_rtp: Fix hold chain bugs caused by native RTP bridge framehookJonathan Rose
Issuing hold/unhold would lead to odd behavior. Between two chan_sip devices, a hold could cause an endless chain of updates while with pjsip a similar chain would begin but then end somewhat randomly. This patch fixes that by no longer tweaking the RTP glue on both sides of the call for every HOLD/UNHOLD/UPDATE_RTP_PEER frame.

2013-07-25A great big renaming patchMatthew Jordan
This patch renames the bridging* files to bridge*. This may seem pedantic and silly, but it fits better in line with current Asterisk naming conventions: * channel is not "channeling" * monitor is not "monitoring" etc. A bridge is an object. It is a first class citizen in Asterisk. "Bridging" is the act of using a bridge on a set of channels - and the API that fulfills that role is more than just the action.

2013-06-12Fix memory leaks in stasis_channels and bridge_native_rtpMatthew Jordan
This patch fixes two memory leaks: * A memory leak in packing channels into a multi-channel blob payload when publishing dial messages. The multi-channel blob payload does not steal the references - this approach was chosen because it works well with the RAII_VAR macro. Unfortunately, this does mean that you actually have to use the RAII_VAR macro (or manually deref it yourself) * RTP instances returned as a result of one of the glue operations are ref counted and have to be de-ref'd appropriately. We now do that, as saying that we should do it and then not would be silly. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@391479 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-06-11bridge_native_rtp: Fix native bridge tech being incompatible when it should be.Jonathan Rose
When checking compatability for the native RTP bridge technology there is a race condition between clearing framehooks that are destroyed when leaving certain bridges with certain technologies (such as bridge_native_rtp) and joining bridges with the bridge_native_rtp technology. Yes, that means a channel in a native RTP bridge could move to another native RTP bridge and be considered incompatible with the new native RTP bridge causing it to revert to a simple bridge technology0. This fixes that bug by ignoring framehooks that have been marked for destruction when checking for compatibility with the bridge_native_rtp technology. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@391453 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2013-06-11bridge_native_rtp: Fix possible segfaults on leaves/joinsJonathan Rose
native_rtp_bridge_get can return any result from the ast_rtp_glue_result enumerator and the join/leave functions for bridge_native_rtp seem to assume that if the result wasn't local that it was remote. Meanwhile forbid can be returned by that function which can mean certain glue pointers are NULL. Then when the join/leave functions try to use members of that pointer, boom. Segfault. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@391430 65c4cc65-6c06-0410-ace0-fbb531ad65f3
