Infinite loop when pinging over WireGuard with peer IP unavailable

[romanrm]

Hello,

Regardless of the WireGuard specifics, when invoked as:

oping -Z 0 -c 1 2620:0:ccc::2

It should do exactly 1 attempt to ping, and exit on success/failure. Instead, this happens:

ping_sendto: Required key not available
ping_send failed: Required key not available

These are written hundreds of times per second, producing 3.5 MB of log for 2 or 3 seconds of operation. And it never exits, unless stopped with Ctrl+C.
