node/npmconf: os.networkInterfaces() appears to fail with EINVAL

Trying to run ungit, have the following error in log output:

[tkelman]

If you follow this into libuv, you can reduce it down to

root@localhost:/home/tkelman# cat getifaddrs.c
#include <stdio.h>
#include <errno.h>
#include <net/if.h>
int main() {
struct ifaddrs *addrs;
int err = getifaddrs(&addrs);
printf("err = %d, errno = %d\n", err, errno);
}
root@localhost:/home/tkelman# gcc -g -o getifaddrs getifaddrs.c
root@localhost:/home/tkelman# ./getifaddrs
err = -1, errno = 22

And if you look at the glibc source for getifaddrs, from what I can tell the failure is in creating a netlink socket, so same as the first item in #69.

[sunilmut]

Yes, NETLINK sockets are currently not implemented. We will be tracking\prioritizing which features to light up next by looking at the feedback provided at the wpdev portal. We appreciate your feedback and please make sure to provide it through the wpdev portal as well. Looks like there is already a post tracking this which you can upvote:

No response for several months. Closing for now. Let us know if this problem persists.

[tkelman]

Still fails exactly the same as it did in April #118 (comment) on build 14915. What change do you believe would have fixed this?

[bitcrazed]

Thanks for responding. Re-opening & investigating.

[jackchammons]

I am no longer seeing this issue in builds 14981+. @jessicah or @tkelman can you confirm that this is no longer an issue.

[tkelman]

On build 14986, my C test case above now gives err = 0, errno = 0 which is encouraging. Would be good to test some higher-level integration use cases like node or julia (if I can remember what used to cause this that led me to getifaddrs, or get my hands on a pre-14981 build to reproduce it again).
