F37 proposal: Deprecate openssl1.1 package (System-Wide Change)

This document represents a proposed Change. As part of the Changes
process, proposals are publicly announced in order to receive
community feedback. This proposal will only be implemented if approved
by the Fedora Engineering Steering Committee.

== Summary ==
We are going to deprecate openssl1.1 package, stop shipping the
corresponding devel package, and stop respecting crypto policies in
openssl1.1 package itself.

== Owner ==
* Name: [[User:DmitryBelyavskiy| Dmitry Belyavskiy]]
* Email: dbelyavs(a)redhat.com

== Detailed Description ==
In Fedora 36 we switched to OpenSSL 3.0 branch. This is a brand new
version with new architecture. We left the openssl1.1 package for the
applications that were unable to switch to the new API/architecture,
3rd-party applications, etc. As openssl 1.1 has a predictable EOL, we
want to ensure that no new products relying on it will appear in
Fedora.

== Benefit to Fedora ==
This proposal ensures than no new packages in Fedora will rely on the
deprecated OpenSSL version that will cause an overall increase of
security/stability, and will reduce the amount of old packages relying
on OpenSSL 1.1 series.

It will also reduce the maintenance burden for the OpenSSL
maintainers, especially when new CVEs are published.

== Scope ==
* Proposal owners:
** Remove devel package
** eliminate crypto policy support from the main package
** provide assistance in migration to other developers

* Other developers:
** Patch their packages to work with OpenSSL 3.0
** Fedora/RHEL distributions provide some syntax sugar related to
https://fedoraproject.org/wiki/Packaging:CryptoPolicies. For the
packages still relying to openssl1.1 the syntax provided by crypto
policies will no longer be supported. The changes implemented
according to https://fedoraproject.org/wiki/Packaging:CryptoPolicies
(e.g. using "PROFILE=SYSTEM" as default TLS ciphersuites
configuration) should be removed.

* Release engineering: This feature doesn't require coordination with
release engineering.
* Policies and guidelines: N/A (not needed for this Change)
* Trademark approval: N/A (not needed for this Change)

== Upgrade/compatibility impact ==
As Crypto Policy support is removed from openssl1.1, applications will
need to adjust the configuration files if they contain the line
"PROFILE=SYSTEM" according to
https://fedoraproject.org/wiki/Packaging:CryptoPolicies

== How To Test ==
Regular application tests should catch the regressions caught by these changes.

== Dependencies ==
No packages should depend on openssl1.1-devel packages that is eliminated.


== Contingency Plan ==
Revert the shipped configuration
Contingency deadline: TBD

== Documentation ==
TBW

== Release Notes ==
TBW
