<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Currently when allocating a channel it is possible for external entities to become aware of the channel and try to interact with it before it is completely set up. This occurs because the channel is returned unlocked, and the caller allocating it is then expected to lock, populate it, and unlock. This leaves a small window where something else can get the channel.
The attached change makes it so ast_channel_alloc returns the allocated channel locked. It is expected that the caller then populates and unlocks. This leaves no window for something external to get and use it.</pre>
