Fedora 33 Accepted System-Wide Changes

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 33 Release as System-Wide Changes.

Aarch64 Pointer Authentication & Branch Target Enablement

Arm Pointer Authentication (PAC) is a method of hardening code from Return Oriented Programming (ROP) attacks. It uses a tag in a pointer to sign and verify pointers. Branch Target Identification (BTI) is another code hardening method, where the branch/jump target is identified with a special landing pad instruction. Outside of some system support in glibc+kernel, packages gain the additional hardening by compiling with the -mbranch-protection= flag available in recent versions of GCC. In particular -mbranch-protection=standard enables both BTI and PAC, with backwards compatible to armv8.0 code sequences that activate on v8.3 (PAC) & v8.5 (BTI) enabled Arm machines.

Make btrfs the default file system for desktop variants

For laptop and workstation installs of Fedora, we want to provide file system features to users in a transparent fashion. We want to add new features, while reducing the amount of expertise needed to deal with situations like running out of disk space. Btrfs is well adapted to this role by design philosophy, let's make it the default.

Cleanup GNOME Hidden Boot Menu Integration

GNOME integrates with Fedora's hidden boot menu feature to signal to the bootloader that boot was successful and to request the menu to be shown the next boot when "Boot Options" is selected in the Shutdown/Reboot dialog. Currently Fedora carries downstream patches for this, which directly call the Fedora specific grub2-set-bootflag helper. The goal of this change is to replace these downstream patches with a clean bootloader agnostic solution which can be submitted upstream.

CMake to do out-of-source builds

%cmake and %cmake_kf5 macros will be adjusted (-B parameter) to use separate build folder (already standardized %{_vpath_builddir} macro). Additionally, %cmake_build, %cmake_install and %ctest macro will be created (and backported to the older supported Fedora releases) to perform various operations that are commonly used with CMake in a backend-agnostic (Makefiles, Ninja, etc.) way.

Enable EarlyOOM on Fedora KDE

As Fedora Workstation did in F32, install earlyoom package, and enable it by default. If RAM goes below 4% free and swap below 10% free, earlyoom issues SIGTERM to the process with the largest oom_score. If RAM goes below 2% free and swap goes below 5% free, earlyoom issues SIGKILL to the process with the largest oom_score. The idea is to recover from out of memory situations sooner, rather than the typical complete system hang in which the user has no other choice but to force power off.

Automatic RPM dependencies on Python Extras

The Python RPM dependency generator (that generates python3.Xdist(foo) requirements) will be adapted to also generate requirements on Python extras (e.g. python3.Xdist(foo[bar])) whenever upstream metadata indicate such dependency.

Change owners will add the missing metapackages that would otherwise cause broken dependencies (in non-modular packages).

Make the unversioned %{__python} macro error by default

Any derived macros (%{python}, %{python_version}, %{python_sitleib} etc.) will propagate the error. Packagers can redefine the macro to any actual value to suppress the error. This is consistent with RHEL 8 behavior. Using /usr/bin/python in Fedora packages remains forbidden.
