Review request for Asterisk Developers.
Bugs: ASTERISK-24600
https://issues.asterisk.org/jira/browse/ASTERISK-24600
Repository: Asterisk
Description
-------
Calling ast_channel_bridge_peer() cannot be done while holding any channel
locks. The reported issue hit the deadlock in chan_iax, but an audit of
the ast_channel_bridge_peer() calls found three more locations where the
same deadlock can occur.
* Made CHANNEL(peer), chan_iax, res_fax, and the SNMP agent not call
ast_channel_bridge_peer() with any channel locked. For CHANNEL(peer) and
chan_iax I had to rework the logic to not hold the channel lock.

Testing
-------
Testsuite tests still pass for FAX. The full testsuite didn't hit any deadlock.
Thanks,
