Systemd socket activation cannot handle a shutdown on the file descriptor[1]. Enumerate past the socket activation descriptors. If there was no shutdown to trigger the breaking of the event loop, then write to the termination_event_fd that was setup during the socket activation code for this purpose. As abort_loop= true is already set at the top of break_connect_loop, and this is checked in loop before sockets are processed, no additional checking to read from the termination_event_fd is needed. Without socket activation defined, or used, termination_event_fd keeps its -1 default value. Close the eventfd outside the while loop so retries can happen if the write fails for some reason. ref[1]: https://www.freedesktop.org/software/systemd/man/latest/sd_listen_fds.html Reviewed by: Vladislav Vaintroub
