1572 | So here's the problem: we'd like to send notification | |
1573 | messages to PID 1, but we cannot do that via sd_notify(), | |
1574 | since that's synchronous, and we might end up blocking on | |
1575 | it. Specifically: given that PID 1 might block on | |
1576 | dbus-daemon during IPC, and dbus-daemon is logging to us, | |
1577 | and might hence block on us, we might end up in a deadlock | |
1578 | if we block on sending PID 1 notification messages -- by | |
1579 | generating a full blocking circle. To avoid this, let's | |
1580 | create a non-blocking socket, and connect it to the | |
1581 | notification socket, and then wait for POLLOUT before we | |
1582 | send anything. This should efficiently avoid any deadlocks, | |
1583 | as we'll never block on PID 1, hence PID 1 can safely block | |
1584 | on dbus-daemon which can safely block on us again. | |
