`failed to fill whole buffer` #247

Closed larseggert closed 1 month ago

larseggert commented 1 month ago

I get failed to fill whole buffer when trying to do an RTM_GETLINK in the recv call at https://github.com/mozilla/mtu/blob/3d3833cca37be85e1c33fdbae196d0aec403617f/src/linux.rs#L116-L120

How can I debug what is causing this?

Turns out I can make this work if I send the second request over a second socket. But I don't understand why reusing the already existing socket is failing.

OK, I figured out that I need to consume all responses before I can reuse the socket for another request.
