Merge ~sergiodj/ubuntu/+source/squid:MRE-5.9-jammy into ubuntu/+source/squid:ubuntu/jammy-devel

[Sergio Durigan Junior]

This is the MRE for squid 5.9.

PPA: https://launchpad.net/~sergiodj/+archive/ubuntu/squid/+packages

dep8 tests are still queued and will probably take some time to run. I'll post results here when I have them.

[Athos Ribeiro (athos-ribeiro)]

Thanks for working on this one, Sergio!

I have a question regarding the following changelog entries:

    - Block all non-localhost requests by default
    - Block to-localhost, to-link-local requests by default

These were included to fix the following upstream bug: https://bugs.squid-cache.org/show_bug.cgi?id=5241

These changes seem to implement alternative B from https://bugs.squid-cache.org/show_bug.cgi?id=5241#c1, which, according to upstream, is "a disruptive change".

I checked the diff between the default config file shipped by our current package and the proposed one, and indeed, this seems to be a disruptive change. Here is the relevant bits of the diff:

I wonder how disruptive these changes would be for users relying on our
include /etc/squid/conf.d/*.conf
entry (i.e., users who will get the configuration file replaced in their working deployments).

I wonder if we should leave those commented out and mention our modifications in the changelog and in the NEWS file.

Thoughts?

Sigh, I missed this one. Sorry.

Which in itself is strange given Alex's comment:

  Such a disruptive change, if approved, will only affect Squid v6+.

Ouch, this is indeed not good.

OK, let me go back to the drawing board and think more about these changes.

[Sergio Durigan Junior (sergiodj)]

So, about leaving a comment on d/NEWS, I'm not entirely sure. By commenting these changes out, we're effectively reverting the configuration file to what it always has been, and therefore there won't be anything new introduced by this release that the users should really be aware of. WDYT?

[Athos Ribeiro (athos-ribeiro)]

I was thinking about the other issue that commenting those out could
generate.

Users getting a fresh install of squid may be led to believe that the
defaults for squid 5.9 are in line with the upstream's defaults. I
understand one should definitely go through their configuration file
before putting such service in production, but maybe
someone will decide do spawn a container in production somewhere just
injecting additional configuration for squid and trusting our defaults
to be aligned with the defaults for that upstream version.

Maybe discussing that in d/NEWS is too much (?), but we could at least
add a comment about that in the changelog to make sure users are aware
of a "deviation" from the upstream intended/suggested default.

That's fair.

We have been commenting out this part for the last seven years:

+-http_access allow localnet
++#http_access allow localnet

and without any kind of warning to the users. But two wrongs don't make
one right.

I will write the entries for d/NEWS and d/changelog.

Hello Athos,

I've added the NEWS entry now. Could you take a look and let me know what you think, please?

Thanks.

[Athos Ribeiro (athos-ribeiro)]

Thanks for addressing that, Sergio :)

- The changelog entry is sane
- The new upstream sources are correctly applied/merged
- The package builds correctly
- Lintian is happy
- The NEWS entry looks great (thank you)

Now, while checking for possible breaking changes in the configuration file, I got:

You're correct again. Thanks for being thorough.

I've uncommented the line and also adjusted the d/NEWS text to remove
its mention there.

Thanks.

+squid (5.9-0ubuntu0.22.04.1) jammy; urgency=medium
+
+  The 5.9 release of Squid introduced more strict defaults when it comes
+  to blocking traffic to localhost and to link-local network address
+  ranges.  In order to guarantee that existing Squid deployments on Ubuntu
+  22.04 Jammy systems continue to work as expected, we decided to disable
+  these defaults and retain the behaviour from previous Ubuntu Squid versions.
+  We do recommend, however, that users take a moment to analyze the new
+  version of the Squid configuration file and determine whether enabling
+  these extra restrictions can be beneficial for their deployments.
+
+  You can see below the excerpt of the Squid configuration file where
+  these restrictions are defined.  In the excerpt below they are enabled,
+  but in the configuration file shipped with the package they will be
+  commented out.
+
+    # Protect web applications running on the same server as Squid. They often
+    # assume that only local users can access them at "localhost" ports.
+    http_access deny to_localhost
+
+    # Protect cloud servers that provide local users with sensitive info about
+    # their server via certain well-known link-local (a.k.a. APIPA) addresses.

 Subject: Default configuration file for debian
 
+Update on 2024-04-10 for the Squid 5.9 MRE:
+
+Upstream, when fixing
+https://bugs.squid-cache.org/show_bug.cgi?id=5241, opted to implement
+option (B) from https://bugs.squid-cache.org/show_bug.cgi?id=5241#c1
+(even though the comment says that such option would only be
+implemented for Squid 6+).  This means that localhost access was
+allowed by default, but two more deny rules were added: deny
+to_localhost and deny to_linklocal.
+
+An MRE should not introduce changes that could be disruptive to the
+users, and that is exactly what these changes are.  As such, we need
+to patch them out in order not to break existing deployments.
