Fix crash in UpnpGetIfInfo #234

Closed jbroadus closed 3 years ago

jbroadus commented 3 years ago

Per getifaddrs documentation, the ifa_addr field of an ifaddrs structure can be null. In a real world example, an entry may be provided for the non-existent hardware address of a tunnel device. This behavior was observed with the netlink based getifaddrs implementation in glibc.

Thanks!

Thanks for merging, but with PR #235, this one is redundant.

mrjimenez commented 3 years ago

Oh, I see. I'll fix the redundancy, but your contribution is registered and your patches are welcome.

Regards, Marcelo.
