As a consequence of its monolithic design, file system code for Linux normally goes into the kernel itself---which is not only a robustness issue, but also an impediment to system extensibility. FUSE, for "file systems in user space", is a kernel module and user-space library that tries to address part of this problem by allowing users to run file system implementations as user-space processes.

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

This package provides a library called libpfm4, which is used to develop monitoring tools exploiting the performance monitoring events such as those provided by the Performance Monitoring Unit (PMU) of modern processors.

Libpfm4 helps convert from an event name, expressed as a string, to the event encoding that is either the raw event as documented by the hardware vendor or the OS-specific encoding. In the latter case, the library is able to prepare the OS-specific data structures needed by the kernel to setup the event.

libpfm4 provides support for the perf_events interface, which was introduced in Linux 2.6.31.

Collection of tools to query what type of USB devices are connected to the system, including lsusb. The experimental usbreset command included in the package, but be aware that it may not work for all devices.

F2FS, the Flash-Friendly File System, is a modern file system designed to be fast and durable on flash devices such as solid-state disks and SD cards. This package provides the userland utilities.

fakeroot runs a command in an environment where it appears to have root privileges for file manipulation. This is useful for allowing users to create archives (tar, ar, deb, etc.) with files in them with root permissions and/or ownership.

Without fakeroot, one would have to have root privileges to create the constituent files of the archives with the correct permissions and ownership, and then pack them up, or one would have to construct the archives directly, without using the archiver.

This package provides statically-linked fsck.f2fs command taken from the f2fs-tools package. It is meant to be used in initrds.

PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc. This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root file system, making files accessible somewhere else in the file system hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode. Also, developers can use PRoot as a generic process instrumentation engine thanks to its extension mechanism. Technically PRoot relies on ptrace, an unprivileged system-call available in the kernel Linux.

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.

pflask is a simple tool for creating Linux namespace containers. It can be used for running a command or even booting an OS inside an isolated container, created with the help of Linux namespaces. It is similar in functionality to chroot, although pflask provides better isolation thanks to the use of namespaces.

This package provides two Linux kernel drivers, ddcci and ddcci-backlight, that allows the control of DDC/CI monitors through the sysfs interface. The ddcci module creates a character device for each DDC/CI monitors in /dev/bus/ddcci/[I²C busnumber]. While the ddcci-backlight module allows the control of the backlight level or luminance property when supported under /sys/class/backlight/.

The Python scripts in this project generate a GTK-UI to change TLP configuration files easily. It aims to protect users from setting bad configuration and to deliver a basic overview of all the valid configuration values.

This package provides many of the missing pieces in GNU libc. Most notably the string functions: strlcpy(3), strlcat(3) and the *BSD sys/queue.h and sys/tree.h API's.

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.

The PSM Messaging API, or PSM API, is Intel's low-level user-level communications interface for the True Scale family of products. PSM users are enabled with mechanisms necessary to implement higher level communications interfaces in parallel environments.

fakechroot runs a command in an environment were is additional possibility to use chroot command without root privileges. This is useful for allowing users to create own chrooted environment with possibility to install another packages without need for root privileges.

It works by providing libfakechroot.so, a shared library meant to be set as LD_PRELOAD to override the C library file system functions.

Aumix adjusts an audio mixer from X, the console, a terminal, the command line or a script.

This simple tool injects fake MCEs into a running Linux kernel, to debug or test the kernel's EDAC-handling code specific to x86 and x86_64 platforms.

Real MCEs are internal CPU errors. Handling them correctly can be important to system stability and even prevent physical damage. In contrast, simulated MCEs produced by mce-inject are purely synthetic: injection happens only at the software level, inside the kernel, and is not visible to the platform hardware or firmware.

A convenient feature of mce-inject is that the input language used to describe MCEs is similar to the format used in Linux panic messages, with a few extensions. In general, you should be able to pipe in any logged MCE panic to simulate that same MCE.

The target kernel must have the CONFIG_X86_MCE_INJECT option enabled and the mce-inject module loaded if it exists.

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.

This package performs runtime integrity checking of the Linux kernel and detection of security vulnerability exploits against the kernel.

nfacct is the command line tool to create/retrieve/delete accounting objects

1. listing the objects of the nfacct table in plain text/XML

2. atomically get and reset objects of the nfacct table

3. adding new objects to the nfacct table

4. deleting objects from the nfacct table

This package provides a statically linked xfs_repair taken from the xfsprogs package. It is meant to be used in initrds.
