dropping Of cert.pem File

This is a proposed Change for Fedora Linux.
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

In order to increase the performance of OpenSSL by default using directory-hash format we need to drop the /etc/pki/tls/cert.pem file to prevent it from being loaded by default.

Owner

• Name: František Krenželok
• Email: fkrenzel@redhat.com

Current status

• Targeted release: Fedora Linux 42
• Last updated: 2024-09-25
• [Announced]
• [<will be assigned by the Wrangler> Discussion thread]
• FESCo issue: <will be assigned by the Wrangler>
• Tracker bug: <will be assigned by the Wrangler>
• Release notes tracker: <will be assigned by the Wrangler>

Detailed Description

In order to improve the loading time of OpenSSL a directory-hash support was added to ca-certificates. In order for OpenSSL to use the directory-hash format by default we need to stop in from trying to load /etc/pki/tls/cert.pem by deleting it.

Benefit to Fedora

Applications using OpenSSL(possibly other libraries as well) will benefit from much faster initialization of OpenSSL.

Scope

• Proposal owners:

The change is already in the rawhide

• Other developers:

Any package loading the root certificates from /etc/pki/tls/cert.pem file need to preferably use the defaults of the library or if they must, use the /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem file instead.

• Release engineering: #Releng issue number

• Policies and guidelines: N/A (not needed for this Change)

• Trademark approval: N/A (not needed for this Change)

• Alignment with the Fedora Strategy:

Early Testing (Optional)

Do you require 'QA Blueprint' support? Y/N

Contingency Plan

• Contingency mechanism: We will postpone the change if majority or critical package owners will be unable to make appropriate changes.
• Contingency deadline: before end of beta freeze(2025-02-18).
• Blocks release? The feature doesn't block release.

Documentation

The change is documented as a part of ca-certificates changelog.

Release Notes
