What do people think about changing the Gnulib documention and code to use HTTPS
instead of HTTP? That should help repel man-in-the-middle attacks.

Absolutely in favour. Man-in-the-middle attacks are *so* easy to perform when
no certificates are involved.

This patch does it for the doc.

We should change them too. I've done that in Gnulib, except for files we import
from elsewhere. I changed gnu.org URLs, along with fsf.org. I did not change
lists.gnu.org or nongnu.org, though, since they don't support HTTPS well enough

It's been years since I read gnu-prog-discuss, but you're welcome to raise the
topic there. To me it's a no-brainer. Code injection attacks are easy with HTTP
and can cause serious damage, and code is the lifeblood of the free-software
movement. Nowadays it is almost irresponsible to encourage the use of HTTP to
distribute code.

I went through all remaining http:// URLs and replaced them with a https://
equivalent if I could find one. In some cases it was easy (e.g. Microsoft
takes care that old URLs keep working), in some other cases it was hard
(e.g. Oracle and HP regularly break URLs and trash published documentation
from their sites).

lists.gnu.org appears to work fine with https, so I included it.

lists.gnu.org appears to work fine with https, so I included it.
https://lists.gnu.org is flaky. Sometimes it works, sometimes it doesn't
work for me. When it doesn't work, it's because I use Firefox configured
with security.tls.version.min set to 2, which means to use TLS 1.1 or
later, and whatever lists.gnu.org clone I happen to contact is
old-fashioned and supports TLS 1.0 at best. (mail.gnu.org is similar.) I
don't observe this problem with other gnu.org URLs. I have tried to open
a trouble ticket about this with the FSF sysadmins, but have received no
response yet.

No big deal; I wouldn't change the URLs back to HTTP as I expect the
matter will be fixed sooner or later.

Well, that's a non-default configuration of Firefox :-)

Indeed, the SSL report of ssllabs.com for lists.gnu.org (208.118.235.17)
says that the server supports only TLS 1.0.

Even if it doesn't get fixed soon: I think it is better if people access
a server over HTTPS with TLS 1.0, rather than with HTTP and no encryption
at all. Even if ssllabs.com explains [1] that "TLS 1.0 is insecure".

So why not force proper software? Have the server require TLS 1.2, disable HTTP. Those who have clients that can't cope, let them sort it out. It doesn't make sense to implement insecure mechanisms to work around people who don't want to use hte right software.
