Fedora 31 Accepted System Wide Changes Proposals

These changes have been accepted by the Fedora Engineering Steering Committee for the Fedora 31 Release as System Wide Changes.

Build non-RELRO ELF binaries with .got.plt isolation

Fedora 23 enabled hardening for all packages. However, some ELF binaries still use lazy binding. This change proposes additional hardening for them.

DNF Better Counting

Right now, we estimate installed Fedora systems by counting unique IP addresses which show up in our updates mirror statistics. We need better data than that. There are some proposals for more complicated systems, but a quick thing we can do now to greatly improve what we have without a gigantic new infrastructure.

Disable Root Password Login in SSH

Gating Rawhide Packages

We want to gate packages on test results before they can land in rawhide. This will reduce the amount of broken dependency, uninstallable packages and broken composes leading to a more stable rawhide as well as less work on the infrastructure and rel-eng teams to keep composes working.

Node.js 12.x by default

Fedora 31 Accepted Self Contained Changes Proposals

Adopt new Go Packaging Guidelines

The current Go packaging guidelines have been in a draft state for several years now, and they do not reflect the current practices from the Go SIG. As a result of new RPM macros developed by Nicolas Mailhot, the Go SIG wishes to formally adopt new Go Packaging Guidelines, which aim at automation, reliability and simplicity.

Firefox Wayland By Default On Gnome

Firefox is going to run natively on Gnome Wayland session and won't use XWayland/X11 Gtk+ backend by default. The XWayland/X11 Gtk+ backend can be still used via additional firefox-x11 package. This change affects Gnome only and won't be enabled for other Wayland compositors (KDE Plasma, Sway).

Improved GRUB menu

Improve the GRUB menu by only having the default boot option for each installed operating system in the main menu, and the other options into a sub-menu. This would better organize the boot options and lead to an easier and seamless boot experience.

glibc 32 Build Adjustments

The glibc32 package is a special package used by gcc and a few other packages to work around the lack of RPM multilib repository support in Koji. It is difficult to maintain, and the current approach raises questions regarding (L)GPL compliance.
