This fix should help resolve some test failures:

That fail with:

AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
+ actual - expected

+ 'Unknown system error -42'
- 'EADDRNOTAVAIL'

}

Node.js v20.0.0-pre

The issues I discovered were 2 fold:

  1. The hasIPv6 function cannot determine IPv6 on IBM i. The loop back interface on IBM i is named *LOOPBACK.

  2. When IPv6 is disabled IBM i returns EUNATCH (errno 42). For now, I've added an errno check in test case for. I believe that libuv needs to get updated to handle EUNATCH so that the error code can be addressed as EUNATCH. Similar to include: add EOVERFLOW status code mapping libuv/libuv#3145

@abmusse Can you rebase this to fix the conflict?

Fixed up the conflict by rebasing and squashed all intermediate commits into one commit.

This fix should help resolve some test failures:

FWIW I ran an IBM i CI build for this:
https://ci.nodejs.org/job/node-test-commit-ibmi/nodes=ibmi73-ppc64/1072
when compared to today's daily IBM i CI:
https://ci.nodejs.org/job/node-test-commit-ibmi/nodes=ibmi73-ppc64/1070
parallel/test-net-autoselectfamily no longer fails 🎉. However parallel/test-net-autoselectfamilydefault is still failing -- presumably this PR should be modifying that test as well based on the PR description.

Good catch @richardlau I need to apply the same errno 42 check in that file as well!

        else if (common.isIBMi) {
          // IBMi returns EUNATCH (ERRNO 42) when IPv6 is disabled
          // keep this errno assertion until EUNATCH is recognized by libuv
          assert.strictEqual(error.errno, -42);
        }

This is not landing cleanly on v18.x

@juanarbol This hasn't gone out in a current release yet so it's too early to be considered for v18.x.

When IPv6 is disabled IBM i returns EUNATCH (errno 42)
instead of EADDRNOTAVAIL.

libuv 1.46.0 adds EUNATCH errno

We can now use error.code to refer to EUNATCH
in node versions that use libuv 1.46.0.
