Fedora 27 talking points

This is a draft!

These are the Talking Points for the Fedora 27 release. For information on how these talking points were chosen, see Talking Points SOP. They are intended to help Ambassadors quickly present an overview of highlighted features when talking about the release, and to help drive content for the release, etc.

The talking points are based in part on the Change Set for this release.

Overall Release Story

Since we skipped the Alpha release for this cycle we just push out the Beta. We had some delays to grant the best stability and operability for our users. The release date is 2017-10-03.

For this cycle, the server edition won't be shipped at the same time due to big changes happening inside the edition itself.

Fedora-Wide Changes and Improvements

All changes are listed below, ones to highlight are listed first

Changes to talk about for regular users

LXQt Spin

A Fedora Spin providing the LXQt desktop environment.

Python Classroom Lab

A new Python Classroom Lab will be created in 3 variants: Workstation based, Docker based and Vagrant based. It's an important step for our Fedora Loves Python initiative. The main audience are Python teachers and workshop instructors.

Changes affecting security

Switch OpenLDAP from NSS to OpenSSL

Currently, OpenLDAP in Fedora is compiled with NSS (aka MozNSS) for cypto. OpenLDAP is going to be compiled with OpenSSL, instead.

Kerberos KCM credential cache by default

Default to a new Kerberos credential cache type called KCM which is better suited for containerized environments and provides a better user experience in the general case as well.

OpenSSL 1.1.0

Rebase of OpenSSL package to 1.1.0 version

OpenSSH Crypto Policy (Client)

OpenSSH client will follow system-wide crypto policies already followed by other cryptographic libraries and tools. It will allow to use different security levels defined system-wide.

Java/OpenJDK enforces the system-wide crypto policy

As it is now, the System-wide crypto policy in F25 is enforced by the OpenSSL, GnuTLS and NSS TLS libraries. To harmonize crypto across all applications in Fedora, including the Java ones, OpenJDK is enhanced to respect the settings of the system-wide crypto policy as well.

Replace Coolkey with OpenSC

There are more PKCS#11 libraries supporting the same smart cards in the system. For the next releases, we would like to promote OpenSC as a default PKCS#11 provided in place where Coolkey driver is used these days, which will

Changes to talk about for developers

GCC7

Switch GCC in Fedora 26 to 7.x.y, rebuild all packages with it, or optionally rebuild just some packages with it and rebuild all packages only in Fedora 27.

Parallel Installable Debuginfo

debuginfo packages can be installed in parallel to make it easier to trace, profile and observe what programs are doing or to debug when they have crashed. That way debugging, tracing or profiling programs can be done independent of whether they are 32bit, 64bit, a slightly newer or older version than currently installed or even from a different architecture.

pkgconf as system pkg-config implementation

This change switches Fedora's system-wide/default pkg-config implementation to pkgconf, a new implementation of pkg-config that provides better support for handling .pc files and a stable library ABI/API for integrating into applications.

Golang 1.8

Rebase of Golang package to upcoming version 1.8 in Fedora 26, including rebuild of all dependent packages.

Ruby 2.4

Ruby 2.4 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.3 in Fedora 24 to Ruby 2.4 in Fedora 26, Fedora becomes the superior Ruby development platform.

Debugging Information For Static Libraries

This change proposes to ship debugging information in static libraries.

Fedora 26 C/C++ Compilation Flags Updates

This change updates the default C/C++ compilation flags, as determined by the redhat-rpm-config package.

Python 3.6

The system Python 3 stack has been upgraded to Python 3.6.1, and includes a backport of Python 3.7's C locale coercion feature (where the ASCII-based C locale is replaced with C.UTF-8 at interpreter startup, which is expected to significantly reduce the occurrence of unwanted Unicode encoding and decoding errors).

All changes

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 26 Release as System Wide Changes.

SSSD fast cache for local users

Enable resolving all users through the sss NSS modules for better performance.

Python Classroom Lab

A new Python Classroom Lab will be created in 3 variants: Workstation based, Docker based and Vagrant based. It's an important step for our Fedora Loves Python initiative. The main audience are Python teachers and workshop instructors.

Kerberos KCM credential cache by default

Default to a new Kerberos credential cache type called KCM which is better suited for containerized environments and provides a better user experience in the general case as well.

GNOME 3.24

Update GNOME to the latest upstream release, 3.24

Enable TRIM pass down to encrypted disks

Override kernel default for dm-crypt mappings of LUKS1 encrypted volumes via flag put in /etc/crypttab file. This change should affect only newly created encrypted storage based on LUKS1 format during installation.

Separate Subpackage and Source Debuginfo

Allow to install just the debuginfo for a subpackage and/or without the source files. The debuginfo packages are huge because they contain debuginfo and all sources for all subpackages. Being able to install only the debuginfo for the subpackage that is installed reduces the size that needs to be downloaded to analyze, trace, profile or debug a program or core file. Some tracing and profiling tools don't need the actual source files to provide stack traces or insert probes. So installing the debugsources should be optional.

Modular Server Preview

As we progress down the modularity path, we finally have enough content, architecture and understanding that we would like to release an edition of Fedora that is actually usable. However, as we aren't ready for production yet, we would like to do a "preview" release so that people can see it and try it but it doesn't actually take the place of a production edition. As such this Change Proposal requests that we set up a "Modular Server Edition" with some sort of flag that indicates that it is meant for experimentation and not real use. We plan to model the Server Edition in content and most use scenarios.

GCC7

Switch GCC in Fedora 26 to 7.x.y, rebuild all packages with it, or optionally rebuild just some packages with it and rebuild all packages only in Fedora 27.

Parallel Installable Debuginfo

debuginfo packages can be installed in parallel to make it easier to trace, profile and observe what programs are doing or to debug when they have crashed. That way debugging, tracing or profiling programs can be done independent of whether they are 32bit, 64bit, a slightly newer or older version than currently installed or even from a different architecture.

Ruby 2.4 is the latest stable version of Ruby. Many new features and improvements are included for the increasingly diverse and expanding demands for Ruby. With this major update from Ruby 2.3 in Fedora 24 to Ruby 2.4 in Fedora 26, Fedora becomes the superior Ruby development platform.

Enable systemd-coredump by default

Enable systemd-coredump by default. Core dumps will be accessible via the coredumpctl tool.

GHC 8.0

Update the GHC Haskell compiler in Fedora from version 7.10 to the current stable version 8.0, with much improved support for aarch64, ppc64, and ppc64le.

Debugging Information For Static Libraries

This change proposes to ship debugging information in static libraries.

Fedora 26 Boost 1.63 upgrade

This change brings Boost 1.63.0 to Fedora 26. This will mean F26 ships with a recent upstream Boost release.

Fedora 26 C/C++ Compilation Flags Updates

This change updates the default C/C++ compilation flags, as determined by the redhat-rpm-config package.

Retire Synaptics Driver

Retire the xorg-x11-drv-synaptics driver and remove it from user's install.

AARCH64 - 48-bit VA

Enable 48bit VA on AARCH64

OpenSSL 1.1.0

Rebase of OpenSSL package to 1.1.0 version

DNF 2.0

DNF rebase to version 2.0.

Python 3.6

Update the Python 3 stack in Fedora from Python 3.5 to Python 3.6.

Fedora 26 Accepted Self Contained Changes Proposals

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 26 Release as Self Contained Changes.

Making sudo pip Safe (Again)

At the present time, running sudo pip3 in Fedora is not safe. Pip shares its installation directory with dnf, can remove dnf-managed files and generally break the Python 3 interpreter. We propose a series of measures that will make it safe to use.

Replace Coolkey with OpenSC

There are more PKCS#11 libraries supporting the same smart cards in the system. For the next releases, we would like to promote OpenSC as a default PKCS#11 provided in place where Coolkey driver is used these days, which will

LDC 1.1.0

Update LDC to 1.1.0 in Fedora 26.

Container Minimal Image

Produce a new container image that contains as little as possible, but also still provides the ability to install packages from dnf repositories.

Docker Overlay 2

Change the default Docker Storage to use OverlayFS via the overlay2 driver, for better performance.

LXQt Spin

A Fedora Spin providing the LXQt desktop environment.

NetworkManager 1.8

Update to NetworkManager to version 1.8.

Automated AMI test and release

We will test the AMI image we build on one single region using the same tests used in Vagrant/local Autocloud testing, and if the tests pass, then only the AMI will be uploaded to all the regions and released.

Fontconfig cache directory change

The fontconfig cache files are placed onto /var/cache/fontconfig now. this seems incompatible with the ostree model. so this is a proposal to move it to /usr/lib/fontconfig/cache.

Base Runtime

We will deliver the first release of Base Runtime, a module providing base operating system features that application level modules can build and depend on. This module will be the foundation of the new modular Fedora 26 Server release.

Golang buildmode PIE

Change default build mode of golang in Fedora packaging macros to buildmode=pie, which results in packages using them to produce Position Independent Executables. Another part of the change is to pass the Fedora hardened linker flags to the external linker(regular system linker). In result reducing exploit-ability of binaries.

Authconfig Cleanup

Removal of obsolete and unmaintainable code from Authconfig such as the support for configuring Hesiod and the authconfig GTK2 based GUI and TUI.

Java/OpenJDK enforces the system-wide crypto policy

As it is now, the System-wide crypto policy in F25 is enforced by the OpenSSL, GnuTLS and NSS TLS libraries. To harmonize crypto across all applications in Fedora, including the Java ones, OpenJDK is enhanced to respect the settings of the system-wide crypto policy as well.

Zend Framework 3

Update Zend Framework to latest version 3.

Modular Compose

For Fedora 26, we would like to modify the compose tools (pungi) to produce an additional experimental variant, derived from modules built in the Module Build Service.

Module Build Service

We will deploy an instance of the Module Build Service to production in Fedora Infrastructure. Other teams will use this service to produce some "modular" content for the Fedora 26 release.

Blivet-GUI in Anaconda

Add blivet-gui as an alternative option for storage configuration in Anaconda Installer.

PHP 7.1

Update the PHP stack in Fedora to latest version 7.1.x

BIND version 9.11

BIND (Berkeley Internet Name Domain) version 9.11 is the latest stable major update of the widely used DNS server. Besides new features, some settings defaults have changed since the previous major version (9.10).

OpenSSH Crypto Policy (Client)

OpenSSH client will follow system-wide crypto policies already followed by other cryptographic libraries and tools. It will allow to use different security levels defined system-wide.

Fedora Atomic

• Consolidated Storage Setup based on OverlayFS - In Fedora Atomic 27 we now default to a more simple container storage setup. In Fedora 26 we switched to overlay as the default driver but we still had a separate volume to for this storage. While we do recommend the separate volume for production deployments we also want a more simple setup for the out-of-the-box experience. In Fedora 27 Atomic Host the default will be a large root filesystem, shared with the container storage (via overlayFS).
• Containerized Kubernetes by Default - Fedora Atomic 27 no longer includes Kubernetes, etcd, or flannel in the base OSTree. We offer containerized Kubernetes, flannel and etcd. This allows flexibility for users to choose different versions of Kubernetes, or to not use Kubernetes at all. If having kubernetes installed via RPM is a requirement, then package layering is still an option.
• Improvements in Package Layering - Latest rpm-ostree, now with support for base package overrides (removes and replaces). This builds on top of the previous features including support for direct rpm install, and experimental LiveFS layering, which allows layering without a reboot.
• System Containers in FLIBS - System Containers, a way of installing system infrastructure software via a container. Since Fedora 26 we have polished the System Container technology and now offer System Containers for Docker, Kuberetes, Flannel, and etcd. These are all available in the Fedora Layered Image Build Service.
• atomic 1.19.1 - An updated to Atomic CLI version 1.19.1, with enhancements/bugfixes to system container support.
• Cockpit XXX - Latest version of Cockpit, including support for Cockpit Dashboard installation on Atomic Host via rpm package layering.

Fedora Server

• FreeIPA 4.5
  • Support for short names for AD users
  • FIPS 140-2 support
  • Client certificate identity mapping
  • Better integration with external DNS servers
  • Fully-customizable certificate authority name
• Cockpit
  • Latest version of Cockpit administration console
  • Show "Locked/Unlocked" indicator for privilege escalation in the top bar
  • Support for configuring kdump kernel crash dumping
  • Cockpit can roll back network configuration that would otherwise disconnect an admin from the system
  • Cockpit is now fully translatable, languages with the best Zanata coverage are Polish, Ukranian, Chinese, and Spanish
  • Cockpit now honors system-defined SSH host keys
  • Cockpit will now generate default certificates with a private CA certificate that can be safely shared
  • Kerberos authentication works even if gss-proxy is in use
  • Improved support for running Cockpit behind a proxy

Fedora Workstation

• Improved Settings - Both the Display and Network areas have been updated to make it simpler to configure these settings, and the overall Settings panel now has a tabbed appearance to make it easier to find the settings you need.
• Builder - features a lot a improvements including to the debugger, the overall design, symbol search and word completion, and inline documentation.
• System search - Has a new layout that shows more results at once -- and even includes system actions.
• System tray removal - the antiquated system tray has been removed to reduce visual clutter and confusion. The Topicons extension is available for use with any applications that have not yet updated to make use of modern GNOME 3 standards.
• Applications
  • LibreOffice 5.4 - TODO: NEEDS NEWER INFO HERE
  • Fedora Media Writer - the new version allows you to create bootable SD cards with Fedora for ARM devices such as Raspberry Pi. Support for Windows 7 and screenshot handling have been improved. The utility also notifies you when a new release of Fedora is available. -- TODO: NEEDS NEWER INFO HERE
