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.

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.

Modular Server

The Modularity Working Group, Factory 2.0, Base Runtime, and Server Working Group would like to propose using the modular infrastructure for creating and delivering the Fedora Server Edition for Fedora 27. While we are still working through some of the kinks leading up to the release of Fedora 26, we believe that the changes to the infrastructure and technology implementations will be available with sufficient time to harden the components in time for the 27 release.

32 bit UEFI Support

Some x86 systems ship with a 64 bit CPU, but 32 bit UEFI firmware. It is possible to use a 32 bit UEFI grub build to boot a 64 bit kernel and distribution on these systems. So far this setup has not been supported in Fedora. This feature is about adding support for installing and booting Fedora on this hardware.

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.

New default cipher in OpenVPN

Since the discovery of the SWEET32 flaw, ciphers using cipher-blocks smaller than 128-bits are considered vulnerable and should not be used any more. OpenVPN uses Blowfish (BF-128-CBC) as the default cipher, which is hit by the SWEET32 flaw. This proposal changes the default cipher to AES-256-GCM while in parallel allowing clients to connect using AES-256-CBC, AES-128-CBC or the deprecated BF-CBC,
