American fuzzy lop is a security-oriented fuzzer that employs a novel type of compile-time instrumentation and genetic algorithms to automatically discover clean, interesting test cases that trigger new internal states in the targeted binary. This substantially improves the functional coverage for the fuzzed code. The compact synthesized corpora produced by the tool are also useful for seeding other, more labor- or resource-intensive testing regimes down the road.

QEMU is a generic machine emulator and virtualizer. This package of QEMU is used only by the american fuzzy lop package.

When used as a machine emulator, QEMU can run OSes and programs made for one machine (e.g. an ARM board) on a different machine---e.g., your own PC. By using dynamic translation, it achieves very good performance.

When used as a virtualizer, QEMU achieves near native performances by executing the guest code directly on the host CPU. QEMU supports virtualization when executing under the Xen hypervisor or using the KVM kernel module in Linux. When using KVM, QEMU can virtualize x86, server and embedded PowerPC, and S390 guests.

C-Vise is a Python port of the C-Reduce tool that is fully compatible and uses the same efficient LLVM-based C/C++ clang_delta reduction tool.

Backward-cpp is a stack trace pretty printer for C++. It can print annotated stack traces using debug info in the executable.

cgdb is a lightweight curses (terminal-based) interface to the GNU Debugger (GDB). In addition to the standard gdb console, cgdb provides a split screen view that displays the source code as it executes. The keyboard interface is modeled after vim, so vim users should feel at home using cgdb.

GNU DDD, the Data Display Debugger, is a graphical front-end for command-line debuggers. Many back-end debuggers are supported, notably the GNU debugger, GDB. In addition to usual debugging features such as viewing the source files, DDD has additional graphical, interactive features to aid in debugging.

Fiu provides CLI utilities and a C library to mark points of failure inside your code and to enable/disable the failure of those points.

rr is a lightweight tool for recording, replaying and debugging execution of applications (trees of processes and threads). Debugging extends GDB with very efficient reverse-execution, which in combination with standard GDB/x86 features like hardware data watchpoints, makes debugging much more fun.

Scanmem is a debugging utility designed to isolate the address of an arbitrary variable in an executing process. Scanmem simply needs to be told the pid of the process and the value of the variable at several different times. After several scans of the process, scanmem isolates the position of the variable and allows you to modify its value.

Zzuf is a transparent application input fuzzer. It works by intercepting file operations and changing random bits in the program's input. Zzuf's behaviour is deterministic, making it easy to reproduce bugs.

This package provides a frontend to GDB, the GNU debugger.

cppdap is a C++11 library ("SDK") implementation of the Debug Adapter Protocol, providing an API for implementing a DAP client or server. cppdap provides C++ type-safe structures for the full DAP specification, and provides a simple way to add custom protocol messages.

Delve is a debugger for the Go programming language.

MspDebug supports FET430UIF, eZ430, RF2500 and Olimex MSP430-JTAG-TINY programmers, as well as many other compatible devices. It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse engineering.

This package includes two Python modules:

1. fiu is a wrapper for libfiu, the fault injection C library.

2. fiu_ctrl provide an easy way run a command with libfiu enabled, and controlling the failure points dynamically.

Stress Make is a customized GNU Make that explicitly manages the order in which concurrent jobs are run to provoke erroneous behavior into becoming manifest. It can run jobs in the order in which they're launched, in backwards order, or in random order. The thought is that if code builds correctly with Stress Make, then it is likely that the Makefile contains no race conditions.

Remake is an enhanced version of GNU Make that adds improved error reporting, better tracing, profiling, and a debugger.

This is a Linux kernel module that implements workarounds needed for using the rr debugger with AMD Zen CPU.

Decker is a multimedia platform for creating and sharing interactive documents, with sound, images, hypertext, and scripted behavior.

DejaGnu is a framework for testing software. In effect, it serves as a front-end for all tests written for a program. Thus, each program can have multiple test suites, which are then all managed by a single harness.

SCMackerel is a library in GNU Guile to create abstract syntax trees (ASTs). Initially written for mCRL2 and now also supporting other languages, such as C, C++, and C#. Based on GNU Guix records.

Dezyne is a programming language and a set of tools to specify, validate, verify, simulate, document, and implement concurrent control software for embedded and cyber-physical systems. The Dezyne language has formal semantics expressed in mCRL2.

Dhall is an explicitly typed configuration language that is not Turing complete. Despite being Turing incomplete, Dhall is a real programming language with a type-checker and evaluator.

Use this library to parse, type-check, evaluate, and pretty-print the Dhall configuration language. This package also includes an executable which type-checks a Dhall file and reduces the file to a fully evaluated normal form.

This package provides SKK-JISYO.L, the standard dictionary file for SKK Japanese input systems, and various dictionary files. SKK-JISYO.L can be used with emacs-ddskk or uim package.
