             Summary: Deadlock potential in res_fax and CCSS with local channels.
                 Key: ASTERISK-22732
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22732
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/CallCompletionSupplementaryServices, Resources/res_fax
    Affects Versions: 12.0.0-beta1, 11.5.1, 1.8.23.1
            Reporter: Richard Mudgett


res_fax and CCSS code call ast_channel_queryoption() with a channel lock held.  If the specified channel is a local channel, there is a deadlock potential due to how local channels have to do deadlock avoidance.

All calls to ast_channel_queryoption() must not have a channel lock held by the caller.

There is a brief discussion about it in https://reviewboard.asterisk.org/r/2915/
