picblobs Guide

Position-independent code blobs for multiple OS/arch targets — how to build, run, extend, and ship them.

Specification

01 Introduction What picblobs is, what it ships, and verified status.

How this concept works

01 How PIC extraction works Plain-language tour of PIC extraction, with diagrams.

User Guide

01 Getting started Prerequisites, the quick-start loop, the dev container. 02 Building Bazel 9, platform configs, debug vs. release, staging. 03 Running blobs Running a blob under QEMU and the test runners. 04 picblobs-cli list, info, extract, run, verify, listing, test. 05 Testing pytest layout, filters, and the testall sweep.

Development

01 Writing a blob Freestanding C, linker conventions, the syscall layer. 02 Code generation What tools/generate.py emits and when to re-run it. 03 Adding an architecture Plumbing a new arch into the registry and toolchains. 04 Adding a syscall Wiring a new syscall through registry and headers. 05 Formatting and linting ruff for Python, clang-format for C, the CI checks.

Reference

01 Platform support Supported OS/arch pairs and their traits. 02 Test runners Linux, FreeBSD, and Windows runner architectures. 03 Project structure Where everything lives in the tree. 04 Kernel toolkit Red-team lab kernel exercise components. 05 Specification Pointers into the spec/ requirements tree.
