fix(udp/unix): don't panic on unknown address family - #2387
Merged
Conversation
We have reports that on some MacOS 10.15 systems, recvmsg can return a non IPv4 or IPv4 `RecvMeta`, potentially due to uninitialized memory. Instead of panicking on an unknown address family, simply return an IO error. Fixes quinn-rs#2383.
