Coccinelle was initially used to aid the evolution of the Linux kernel, providing support for changes to library application programming interfaces (APIs) such as renaming a function, adding a function argument whose value is somehow context-dependent, and reorganizing a data structure.
The project's maintainer can then scan through the list of patches, marking each with a certain state, such as Accepted, Rejected or Under Review. Old patches can be sent to the archive or deleted. Currently, Patchwork is being used for a number of open-source projects, mostly subsystems of the Linux kernel and FFmpeg. Although Patchwork has ...
For example, quilt is heavily used by the maintainers of the Linux kernel. [ 2 ] Quilt evolved from a set of patch-management scripts originally written by Linux kernel developer Andrew Morton , [ 3 ] and was developed by Andreas Grünbacher for maintaining Linux kernel customizations for SuSE Linux . [ 4 ]
KernelCare is a live kernel patching service that provides security patches and bugfixes for a range of popular Linux kernels [2] that can be installed without rebooting the system. [3] KernelCare software is a commercial product. The first beta was introduced in March 2014 and it was commercially launched in May 2014.
Ksplice is an open-source [2] [3] extension of the Linux kernel that allows security patches to be applied to a running kernel without the need for reboots, avoiding downtimes and improving availability (a technique broadly referred to as dynamic software updating). Ksplice supports only the patches that do not make significant semantic changes ...
Salt (sometimes referred to as SaltStack) is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. Supporting the " infrastructure as code " approach to data center system and network deployment and management, configuration automation, SecOps orchestration, vulnerability ...
kGraft is a feature of the Linux kernel that implements live patching of a running kernel, which allows kernel patches to be applied while the kernel is still running. By avoiding the need for rebooting the system with a new kernel that contains the desired patches, kGraft aims to maximize the system uptime and availability.
In computing, copy-and-patch compilation is a simple compiler technique intended for just-in-time compilation (JIT compilation) that uses pattern matching to match pre-generated templates to parts of an abstract syntax tree (AST) or bytecode stream, and emit corresponding pre-written machine code fragments that are then patched to insert memory addresses, register addresses, constants and ...
