Yes, itʼs the same bug.
commit 6dc4fc7d62 from the emacs repository will fix it, and should
apply without issues to emacs-27 if you want to carry a local patch.

Thank you very much. That was the information I was looking for :-).

I've been consistently seeing the following error when running 'make
check' for a while. It corresponds to the line in nsm-tests.el where
nsm-trust-local-network is bound to t.

I stepped through nsm-should-check a bit, but I don't understand what is
or should be happening. The test fails when local var off-net is set to
nil, which happens when nsm-network-same-subnet returns non-nil. This
happens with the following local var values:
ip: [0 0 0 0 0 0 0 1 0]
info: (lo [0 0 0 0 0 0 0 1 0]
[0 0 0 0 0 0 0 1 0]
[65535 65535 65535 65535 65535 65535 65535 65535 0])
addresses: ([0 0 0 0 0 0 0 1 0])
network-interface-list:
((wlp3s0 [65152 0 0 0 38609 2370 19874 38730 0]
[65152 0 0 0 65535 65535 65535 65535 0]

(lo [127 0 0 1 0] [127 255 255 255 0] [255 0 0 0 0]))
I've observed that the test fails only on my home network. I've heard
that my ISP and the modem they provide use a weird dual IPv6 stack that
has caused people problems in the past, but I know next to nothing about
these things and can't say if it's related to the issue at hand.
Another observation is that the test succeeds if I replace "google.com"
with "gnu.org". Should I just change the test to use "gnu.org", and
forget about this? Or is there some interesting issue here? Any
suggestions or guidance are very welcome.
Here's my /etc/resolv.conf, in case it matters:
# Generated by NetworkManager
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 2001:4860:4860::8888
# NOTE: the libc resolver may not support more than 3 nameservers.
# The nameservers listed below may not be recognized.
nameserver 2001:4860:4860::8844
[ I've been pointing my DNS settings to Google ever since I spent some
months in a country with very poor network services. ]
Thanks,

There is no way that 'network-lookup-address-info' on google.com
should return ::1. You donʼt have a spare entry lying around in
/etc/hosts for google.com by any chance?
What do you get for
(network-lookup-address-info "google.com")
(network-lookup-address-info "google.com" 'ipv4)
(network-lookup-address-info "google.com" 'ipv6)
How about:
(require 'dns)
(dns-query "google.com" 'A)
(dns-query "google.com" 'AAAA)

Most IPv6 stacks are dual stack IPv4/IPv6. Do they mean they're doing
IPv4 in IPv6 in some way? Which ISP is this?

And what do you get for
dig -t A google.com
dig -t AAAA google.com
This might be interesting as well:

Oops, sorry! I must have been looking at the wrong value. There are
two cases where nsm-network-same-subnet returns non-nil, and in both
cases:

2. [10752 5200 16395 3073 0 0 0 113 0]

Sorry, I don't know. Is there a way to find out that doesn't involve

Virgin Media in Ireland.

FWIW, this also happened on my older laptop, not just this new one I'm
writing from. Both run the same suite of Debian, Systemd,
NetworkManager, etc.
Let me know what else I can do, and thanks for your help,

Hi!
We're seeing this failure as well in Debian on 32-bit PowerPC [1]:
Test nsm-check-local-subnet-ipv4 condition:
(ert-test-failed
((should
(eq t
(nsm-should-check "google.com")))
:form
(eq t nil)
:value nil))
FAILED 1/2 nsm-check-local-subnet-ipv4 (0.002883 sec)
passed 2/2 nsm-check-local-subnet-ipv6 (0.000447 sec)
Ran 2 tests, 1 results as expected, 1 unexpected (2021-03-30 13:14:28+0000, 0.164994 sec)
1 unexpected results:
FAILED nsm-check-local-subnet-ipv4
Any chance that this is the same bug?
Thanks,
Adrian
