Top 13 Go Kernel Projects

• cilium

  24 18,628 10.0 Go

  eBPF-based Networking, Security, and Observability

  

Project mention: Cisco to Acquire Cloud Native Networking and Security Leader Isovalent | news.ycombinator.com | 2023-12-21

They would have had to add a few externals to get to Graduated but it's definitely a minority:

• gvisor

  64 15,118 9.9 Go

  Application Kernel for Containers

  

Project mention: Maestro: A Linux-compatible kernel in Rust | news.ycombinator.com | 2024-01-03

Isn't gVisor kind of this as well?

"gVisor is an application kernel for containers. It limits the host kernel surface accessible to the application while still giving the application access to all the features it expects. Unlike most kernels, gVisor does not assume or require a fixed set of physical resources; instead, it leverages existing host kernel functionality and runs as a normal process. In other words, gVisor implements Linux by way of Linux."

• syzkaller

  7 5,143 9.8 Go

  syzkaller is an unsupervised coverage-guided kernel fuzzer

  

Project mention: Automated Unit Test Improvement Using Large Language Models at Meta | news.ycombinator.com | 2024-02-17

https://arxiv.org/abs/2402.09171 :

> This paper describes Meta's TestGen-LLM tool, which uses LLMs to automatically improve existing human-written tests. TestGen-LLM verifies that its generated test classes successfully clear a set of filters that assure measurable improvement over the original test suite, thereby eliminating problems due to LLM hallucination. [...] We believe this is the first report on industrial scale deployment of LLM-generated code backed by such assurances of code improvement.

Coverage-guided unit test improvement might [with LLMs] be efficient too.

- e.g. Google/syzkaller is a coverage-guided syscall fuzzer: https://github.com/google/syzkaller

- Gitlab CI supports coverage-guided fuzzing: https://docs.gitlab.com/ee/user/application_security/coverag...

- oss-fuzz, osv

Additional ways to improve tests:

Hypothesis and pynguin generate tests from type annotations.

There are various tools to generate type annotations for Python code;

> pytype (Google) [1], PyAnnotate (Dropbox) [2], and MonkeyType (Instagram) [3] all do dynamic / runtime PEP-484 type annotation type inference [4] to generate type annotations. https://news.ycombinator.com/item?id=39139198

icontract-hypothesis generates tests from icontract DbC Design by Contract type, value, and invariance constraints specified as precondition and postcondition @decorators:

I've had this bookmarked for some time and just havent gotten around to it.

• tetragon

  eBPF-based Security Observability and Runtime Enforcement

  

Project mention: Linux runtime security agent powered by eBPF | news.ycombinator.com | 2023-10-19

• u-root

  9 2,448 9.7 Go

  A fully Go userland with Linux bootloaders! u-root can create a one-binary root file system (initramfs) containing a busybox-like set of tools written in Go.

  

Project mention: Monogon: A Linux userland in pure Go | news.ycombinator.com | 2024-03-28

It looks similar to u-root https://github.com/u-root/u-root, yes, used as part of host firmware. There's a description of u-root in chapter 6 of https://link.springer.com/book/10.1007/978-1-4842-7939-7, too.

• procfs

  2 740 8.4 Go

  procfs provides functions to retrieve system, kernel and process metrics from the pseudo-filesystem proc.

  

• schedviz

  1 511 0.0 Go

  A tool for gathering and visualizing kernel scheduling traces on Linux machines

  

Project mention: The Linux Scheduler: A Decade of Wasted Cores (2016) [pdf] | news.ycombinator.com | 2023-12-13

I'd like to wager that EEVDF has been tested less methodologically than how this paper investigates CFS. The primary author of EEVDF and maintainer of the subsystem has been dismissing alternative approaches and plethora of robustly tested patches from Google and Facebook over the years, with mostly replies boiling down to "meh I don't like it".

I'd take a patch of CFS and its millions of broken knobs from Google over newly released EEVDF any day, because I trust scheduler AB testing by Google over millions of machines and every single scheduling pattern under the sun way more than whatever synthetic micro-benchmark a single kernel dev (as competent as they might be) ran.

If you're interested in quantitative analysis of schedulers & tooling around it, these 2 projects are very interesting:

• btfhub

  1 332 6.6 Go

  BTFhub, in collaboration with the BTFhub Archive repository, supplies BTF files for all published kernels that lack native support for embedded BTF. This joint effort ensures that even kernels without built-in BTF support can effectively leverage the benefits of eBPF programs, promoting compatibility across various kernel versions.
