libslirp is a user-mode networking library used by virtual machines, containers or various tools.

This package provides Container Network Interface (CNI) plugins to configure network interfaces in Linux containers.

This package provides a replacement for libslirp and VPNKit, written in pure Go. It is based on the network stack of gVisor and brings a configurable DNS server and dynamic port forwarding.

It can be used with QEMU, Hyperkit, Hyper-V and User-Mode Linux.

The binary is called gvproxy.

Buildah is a command-line tool to build OCI container images. More generally, it can be used to:

• create a working container, either from scratch or using an image as a starting point;

• create an image, either from a working container or via the instructions in a Dockerfile;

• mount a working container's root filesystem for manipulation;

• use the updated contents of a container's root filesystem as a filesystem layer to create a new image.

Conmon is a monitoring program and communication tool between a container manager (like Podman or CRI-O) and an Open Container Initiative (OCI) runtime (like runc or crun) for a single container.

passt implements a thin layer between guest and host, that only implements what's strictly needed to pretend processes are running locally. The TCP adaptation doesn't keep per-connection packet buffers, and reflects observed sending windows and acknowledgements between the two sides. This TCP adaptation is needed as passt runs without the CAP_NET_RAW capability: it can't create raw IP sockets on the pod, and therefore needs to map packets at Layer-2 to Layer-4 sockets offered by the host kernel.

Also provides pasta, which similarly to slirp4netns, provides networking to containers by creating a tap interface available to processes in the namespace, and mapping network traffic outside the namespace using native Layer-4 sockets.

Catatonit is a simple container init tool developed as a rewrite of initrs in C due to the need for static compilation of Rust binaries with musl. Inspired by other container inits like tini and dumb-init, catatonit focuses on correct signal handling, utilizing signalfd(2) for improved stability. Its main purpose is to support the key usage by docker-init: /dev/init – <your program>, with minimal additional features planned.

crun is a fast and low-memory footprint Open Container Initiative (OCI) Container Runtime fully written in C.

Distrobox is a fancy wrapper around Podman or Docker to create and start containers highly integrated with the hosts.

Podman (the POD MANager) is a tool for managing containers and images, volumes mounted into those containers, and pods made from groups of containers.

Not all commands are working out of the box due to requiring additional binaries to be present in the $PATH.

To get podman compose working, install either podman-compose or docker-compose packages.

To get podman machine working, install qemu-minimal, and openssh packages.

This package provides a tool for exploring a Docker image, layer contents, and discovering ways to shrink the size of Docker/OCI image.

slirp4netns provides user-mode networking ("slirp") for unprivileged network namespaces.

convmv is a file renamer, that converts between different encodings, e.g. from ISO-8859-1 to UTF-8. It is particularly usefuls for files with names, that display incorrectly.

This project contains an extended "Standard Library" for Coq called coq-std++. The key features are:

• Great number of definitions and lemmas for common data structures such as lists, finite maps, finite sets, and finite multisets.

• Type classes for common notations (like ∅, ∪, and Haskell-style monad notations) so that these can be overloaded for different data structures.

• It uses type classes to keep track of common properties of types, like it having decidable equality or being countable or finite.

• Most data structures are represented in canonical ways so that Leibniz equality can be used as much as possible (for example, for maps we have m1 = m2 iff ∀ i, m1 !! i = m2 !! i). On top of that, the library provides setoid instances for most types and operations.

• Various tactics for common tasks, like an ssreflect inspired done tactic for finishing trivial goals, a simple breadth-first solver naive_solver, an equality simplifier simplify_eq, a solver solve_proper for proving compatibility of functions with respect to relations, and a solver set_solver for goals involving set operations.

• The library is dependency- and axiom-free.

Interval provides vernacular files containing tactics for simplifying the proofs of inequalities on expressions of real numbers for the Coq proof assistant.

Mathematical Components for Coq has its origins in the formal proof of the Four Colour Theorem. Since then it has grown to cover many areas of mathematics and has been used for large scale projects like the formal proof of the Odd Order Theorem.

The library is written using the Ssreflect proof language that is an integral part of the distribution.

Coq is a proof assistant for higher-order logic, which allows the development of computer programs consistent with their formal specification. It is developed using Objective Caml and Camlp5.

Gappa is a tool intended to help verifying and formally proving properties on numerical programs dealing with floating-point or fixed-point arithmetic. It has been used to write robust floating-point filters for CGAL and it is used to certify elementary functions in CRlibm. While Gappa is intended to be used directly, it can also act as a backend prover for the Why3 software verification plateform or as an automatic tactic for the Coq proof assistant.

Formalizing syntactic theories with variable binders is not easy. Autosubst is a library for the Coq proof assistant to automate this process. Given an inductive definition of syntactic objects in de Bruijn representation augmented with binding annotations, Autosubst synthesizes the parallel substitution operation and automatically proves the basic lemmas about substitutions. This library contains an automation tactic that solves equations involving terms and substitutions. This makes the usage of substitution lemmas unnecessary. The tactic is based on our current work on a decision procedure for the equational theory of an extension of the sigma-calculus by Abadi et al. The library is completely written in Coq and uses Ltac to synthesize the substitution operation.

The package is used for reasoning with big enough objects (mostly natural numbers). This package is essentially for backward compatibility purposes as bigenough will be subsumed by the near tactics. The formalization is based on the Mathematical Components library.

This package provides a survey of programming language semantics styles, from natural semantics through structural operational, axiomatic, and denotational semantics, for a miniature example of an imperative programming language. Their encoding, the proofs of equivalence of different styles, abstract interpretation, and the proof of soundess obtained from axiomatic semantics or abstract interpretation is done in Coq. The tools can be run inside Coq, thus making them available for proof by reflection. Code can also be extracted and connected to a yacc-based parser, thanks to the use of a functor parameterized by a module type of strings. A hand-written parser is also provided in Coq, without associated proofs.

This library is an extension of coq-mathcomp which supports finite sets and finite maps on choicetypes (rather than finite types). This includes support for functions with finite support and multisets. The library also contains a generic order and set library, which will eventually be used to subsume notations for finite sets.

Flocq (Floats for Coq) is a floating-point formalization for the Coq system. It provides a comprehensive library of theorems on a multi-radix multi-precision arithmetic. It also supports efficient numerical computations inside Coq.

Bignums is a coq library of arbitrary large numbers. It provides BigN, BigZ, BigQ that used to be part of Coq standard library.
