Some of our tests require internet connectivity / an IPv4 stack

We got word from an onion service operator that they had to disable some of our tests because they wouldn't work in their ipv6-only setup.

In particular they mentioned the following tests (or functions): get_if_addrs_list_internal, get_if_addrs_list_no_internal, get_if_addrs, status_vote_current_consensus_ns

We should probably investigate this.

I managed to repro a failure in util/socketpair_ersatz using unshare, and so made a child ticket to fix it. Everything else in ./src/test/test worked fine.

Hi! I'd be glad to try to fix this stuff, but I'd need more info to do so. Reproduction instructions would be best, along with complete logs from the failing tests.

I regularly run our tests on a macOS VM without any network connection. (But with IPv4 and IPv6 stacks.) They work fine.

Our CI runs tests online with IPv4 (Travis Linux), and dual-stack (Travis Mac). (Appveyor doesn't mention IP stacks in its documentation, we use it for Windows builds.)

I'll try to run tests on macOS and Linux VMs with only an IPv6 stack.

Linus also had some IPv6 only machines. I don't know if they're still available.

Sent an email to the bug reporter to clarify in this ticket :)

Replying to teor:

The Linux system is gone and the FreeBSD system is in need of a shape-up. Let me know if I should bring one or both back!

To be clear, these would have IP stacks but no IPv4 connectivity.
