The inih (INI Not Invented Here) library is a simple .INI file parser written in C. It's only a couple of pages of code, and it was designed to be small and simple, so it's good for embedded systems. It's also more or less compatible with Python's ConfigParser style of .INI files, including RFC 822-style multi-line syntax and name: value entries.

Libraw1394 is the only supported interface to the kernel side raw1394 of the Linux IEEE-1394 subsystem, which provides direct access to the connected 1394 buses to user space. Through libraw1394/raw1394, applications can directly send to and receive from other nodes without requiring a kernel driver for the protocol in question.

This is a collection of tests written over uverbs intended for use as a performance micro-benchmark. The tests may be used for hardware or software tuning as well as for functional testing.

The collection contains a set of bandwidth and latency benchmark such as:

1. Send - ib_send_bw and ib_send_lat

2. RDMA Read - ib_read_bw and ib_read_lat

3. RDMA Write - ib_write_bw and ib_wriet_lat

4. RDMA Atomic - ib_atomic_bw and ib_atomic_lat

5. Native Ethernet (when working with MOFED2) - raw_ethernet_bw, raw_ethernet_lat

Singularity is a container platform supporting a number of container image formats. It can build SquashFS container images or import existing Docker images. Singularity requires kernel support for container isolation or root privileges.

bpftrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). bpftrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities: kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. The bpftrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap. bpftrace was created by Alastair Robertson.

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.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. The software includes sandbox profiles for a number of common Linux programs. Firejail should be added to the list of setuid programs in the system configuration to work properly.

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.

The SBC is a digital audio encoder and decoder used to transfer data to Bluetooth audio output devices like headphones or loudspeakers.

Libbpf supports building BPF CO-RE-enabled applications, which, in contrast to BCC, do not require the Clang/LLVM runtime or linux kernel headers.

evtest is a tool to print evdev kernel events. It reads directly from the kernel device and prints a device description and the events with the value and the symbolic name.

Headers of the Linux-Libre kernel.

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.

x86_energy_perf_policy displays and updates energy-performance policy settings specific to Intel Architecture Processors. Settings are accessed via Model Specific Register (MSR) updates, no matter if the Linux cpufreq sub-system is enabled or not.

The Falco security libraries include libsinsp and libscap. libscap manages the data capture process, while libsinsp is a system inspection library that enriches events from libscap with machine state. libsinsp also performs events filtering with rule evaluation through its internal rule engine. These libraries are used by the sysdig command-line utility.

This package provides a shell script to assess your system's resilience against the several transient execution CVEs that were published since early 2018, and gives guidance as to how to mitigate them.

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.

strace is a system call tracer, i.e. a debugging tool which prints out a trace of all the system calls made by a another process/program.

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

eCryptfs is a POSIX-compliant stacked cryptographic file system for Linux. Each file's cryptographic meta-data is stored inside the file itself, along with the encrypted contents. This allows individual encrypted files to be copied between hosts and still be decrypted with the proper key. eCryptfs is a native Linux file system, and has been part of the Linux kernel since version 2.6.19. This package contains the userland utilities to manage it.

This program allows you read and control device brightness. Devices include backlight and LEDs. It can also preserve current brightness before applying the operation, such as on lid close.

The appropriate permissions must be set on the backlight or LED control interface in sysfs, which can be accomplished with the included udev rules.

This package provides a Python library to access I2C and SMBus devices on Linux.

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.

libnfnetlink is the low-level library for netfilter related kernel/userspace communication. It provides a generic messaging infrastructure for in-kernel netfilter subsystems (such as nfnetlink_log, nfnetlink_queue, nfnetlink_conntrack) and their respective users and/or management tools in userspace.
