How do I use getifaddr() in Gramine Shielded Containers?

[fwoodruff]

I have a (third-party) C++ program I am able to create a Docker image for (built with Make). I have tried building a 'Graminised' version to run inside SGX. The program produces the same logs initially but differs after:

getNetworkInfo() failed calling getifaddrs() iResult=-1=Unknown error -1

I believe this is the Linux library function I need supported. Is this something I can achieve by updating the Gramine manifest file for example?

getifaddrs() uses the AF_NETLINK socket type which is not implemented in Gramine, at least yet.

You can find some info and potential workarounds here:
