New Revision: 395574
URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=395574
Log:
Remove the unsafe bridge parameter from ast_bridge_hook_callback's.
Most hook callbacks did not need the bridge parameter. The pointer value
could become invalid if the channel is moved to another bridge while it is
executing.
* Fixed some issues in feature_attended_transfer() as a result.
* Reduce the bridge inhibit count in
attended_transfer_properties_shutdown() after it has restored the bridge
channel hooks.
* Removed basic bridge requirement on feature_blind_transfer(). It does
not require the basic bridge like feature_attended_transfer().
