Dual Function Keys is a plugin for interception-tools that allows one to send arbitrary keycodes when a given key is tapped or held.

libnetfilter_log is a userspace library providing interface to packets that have been logged by the kernel packet filter. It is is part of a system that deprecates the old syslog/dmesg based packet logging. This library has been previously known as libnfnetlink_log.

This simple daemon feeds entropy from the CPU Jitter RNG core to the kernel Linux's entropy estimator. This prevents the /dev/random device from blocking and should benefit users of the preferred /dev/urandom and getrandom() interfaces too.

The CPU Jitter RNG itself is part of the kernel and claims to provide good entropy by collecting and magnifying differences in CPU execution time as measured by the high-resolution timer built into modern CPUs. It requires no additional hardware or external entropy source.

The random bit stream generated by jitterentropy-rngd is not processed by a cryptographically secure whitening function. Nonetheless, its authors believe it to be a suitable source of cryptographically secure key material or other cryptographically sensitive data.

If you agree with them, start this daemon as early as possible to provide properly seeded random numbers to services like SSH or those using TLS during early boot when entropy may be low, especially in virtualised environments.

Wireless Tools are used to manipulate the now-deprecated Linux Wireless Extensions; consider using iw instead. The Wireless Extension was an interface allowing you to set Wireless LAN specific parameters and get the specific stats. It is deprecated in favor the nl80211 interface.

This package provides commands to create and check XFS file systems.

The CRDA acts as the udev helper for communication between the kernel Linux and user space for regulatory compliance.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

GNU Linux-Libre is a free (as in freedom) variant of the Linux kernel. It has been modified to remove all non-free binary blobs.

PipeWire is a project that aims to greatly improve handling of audio and video under Linux. It aims to support the usecases currently handled by both PulseAudio and Jack and at the same time provide same level of powerful handling of Video input and output. It also introduces a security model that makes interacting with audio and video devices from containerized applications easy, with supporting Flatpak applications being the primary goal. Alongside Wayland and Flatpak we expect PipeWire to provide a core building block for the future of Linux application development.

Kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.

These tools are designed on top of libkmod, a library that is shipped with kmod. The aim is to be compatible with tools, configurations and indices from the module-init-tools project.

Libmnl is a minimalistic user-space library oriented to Netlink developers. There are a lot of common tasks in parsing, validating, constructing of both the Netlink header and TLVs that are repetitive and easy to get wrong. This library aims to provide simple helpers that allows you to re-use code and to avoid re-inventing the wheel.

mbpfan is a fan control daemon for Apple Macbooks. It uses input from the coretemp module and sets the fan speed using the applesmc module. It can be executed as a daemon or in the foreground with root privileges.

BCC is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature that was first added to Linux 3.15. Much of what BCC uses requires Linux 4.1 and above.

The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux-based operating system.

Zerofree finds the unallocated blocks with non-zero value content in an ext2, ext3, or ext4 file system and fills them with zeroes (or another value). This is a simple way to make disk images more compressible. Zerofree requires the file system to be unmounted or mounted read-only.

This package contains keytable files and keyboard utilities compatible for systems using the Linux kernel. This includes commands such as loadkeys, setfont, kbdinfo, and chvt.

Libnftnl is a userspace library providing a low-level netlink programming interface to the in-kernel nf_tables subsystem. The library libnftnl has been previously known as libnftables. This library is currently used by nftables.

This package provides a way to access the System Management Unit for certain AMD Ryzen processors. This includes access to the System Management Network.

Cramfs is a Linux file system designed to be simple, small, and to compress things well. It is used on a number of embedded systems and small devices. This version has additional features such as uncompressed blocks and random block placement.

This package provides a program to generate an ext2 file system as a normal (non-root) user. It does not require you to mount the image file to copy files on it, nor does it require that you become the superuser to make device nodes.

mdadm is a tool for managing Linux Software RAID arrays. It can create, assemble, report on, and monitor arrays. It can also move spares between raid arrays when needed.

Python-evdev provides bindings to the generic input event interface in Linux. The evdev interface serves the purpose of passing events generated in the kernel directly to userspace through character devices that are typically located in /dev/input/.

This package also comes with bindings to uinput, the userspace input subsystem. uinput allows userspace programs to create and handle input devices that can inject events directly into the input subsystem.
