Joshua Colp 23b7b109c2 bridge_native_rtp.c: Don't start native RTP bridging after attended transfer. ... The bridge_native_rtp module adds a frame hook to channels which are in a native RTP bridge. This frame hook is used to intercept when a hold or unhold frame traverses the bridge so native RTP can be stopped or started as appropriate. This is expected but exposes a specific bug when attended transfers are involved. Upon completion of an attended transfer an unhold frame is queued up to take one of the channels involved off hold. After this is done the channel is moved between bridges. When the frame hook is involved in this case for the unhold it releases the channel lock and acquires the bridge lock. This allows the bridge core to step in and move the channel (potentially changing the bridging techology) from another thread. Once completed the bridge lock is released by the bridge core. The frame hook is then able to acquire the bridge lock and wrongfully starts native RTP again, despite the channel no longer being in the bridge or needing to start native RTP. In fact at this point the frame hook is no longer attached to the channel. This change makes it so the native RTP bridge data is available to the frame hook when it is invoked. Whether the frame hook has been detached or not is stored on the native RTP bridge data and is checked by the frame hook before starting or stopping native RTP bridging. If the frame hook has been detached it does nothing. ASTERISK-25240 #close Change-Id: I13a73186a05f4e5a764f81e5cd0ccec1ed1891d2		10 years ago
