jpeeler (301790):
>Resolve deadlock involving REFER.
>
>Two fixes:
>1) One must always have the private unlocked before calling
>pbx_builtin_setvar_helper to not invalidate locking order since it locks the
>channel.
>2) Unlock the channel before calling pbx_find_extension, which starts and stops
>autoservice during the lookup. The problem scenario as illustrated by the
>reporter:
>
>Thread: do_monitor
>-----------------------
>handle_request_do
> handle_incoming
> handle_request_refer
> ast_parking_ext_valid
> pbx_find_extension
> ast_autoservice_stop
> while (chan_list_state == as_chan_list_state) { usleep(1000); }
>
>Thread: autoservice_run
>-----------------------
>autoservice_run
> chan = ast_waitfor_n
> ast_waitfor_nandfds
> ast_waitfor_nandfds_classic / simple / complex (depending on your system)
> ast_channel_lock(c[x]);
>
>handle_request_do and schedule_process_request_queue locks the owner
>if it exists. The autoservice thread is waiting for the channel lock, which
>wasn't ever released since the do_monitor thread was waiting for autoservice
>operations to complete. Solved by unlocking the channel but keeping a reference
>to guarantee safety.
