squid: Fail to build against OpenSSL 3.0

[Simon Chopin]

Hello,

As part of a rebuild against OpenSSL3, this package failed to build on one or
several architectures. You can find the details of the rebuild at

https://people.canonical.com/~schopin/rebuilds/openssl-3.0.0-impish.html

or for the amd64 failed build, directly at

https://launchpad.net/~schopin/+archive/ubuntu/openssl-3.0.0/+build/22099383/+files/buildlog_ubuntu-impish-amd64.squid_4.13-10ubuntu4.0~ssl3ppa1.1_BUILDING.txt.gz

We're planning to transition to OpenSSL 3.0 for the 22.04 release, and consider
this issue as blocking for this transition.

You can find general migration informations at
https://www.openssl.org/docs/manmaster/man7/migration_guide.html
For your tests, you can build against libssl-dev as found in the PPA
schopin/openssl-3.0.0

There's a draft PR upstream to port squid to OpenSSL 3.0, see
https://github.com/squid-cache/squid/pull/694

[Simon Chopin (schopin)]

Patch based on the PR linked above, uploaded to both
https://launchpad.net/~schopin/+archive/ubuntu/test-ppa/ (libssl1.1)
and
https://launchpad.net/~schopin/+archive/ubuntu/foundation-openssl3/ (libssl3)

The autopkgtests fail currently because of https://bugs.launchpad.net/ubuntu/+source/apache2/+bug/1951476

[Sergio Durigan Junior (sergiodj)]

Yeah, I'm still testing the upstream patch. They asked for more testers/reviewers and I intend to provide some feedback there, but we're unfortunately blocked on the apache2 bug (which is preventing us from running autopkgtest).
