connection_write_to_buf: indirect recursion for CONN_TYPE_CONTROL
connection_write_to_buf for CONN_TYPE_CONTROL allows immediate flush of the outbuf. Then if code tries to log something and
control_event_logmsg is involved then it call of
connection_write_to_buf recursively. Consequence calls blocked by
++disable_log_messages only then.
Three ways to fix:
- Remove ability for immediate flush of the outbuf by
in_connection_handle_writeflag at start of
- Guard call of
Every way have negative and positive impacts.
