Introduce go.mod with Go 1.26 toolchain and fix vet/platform issues in client tests so go test ./... passes on current Go. Made-with: Cursor
Document the repository structure, module-based usage, and track modernization changes and follow-ups. Made-with: Cursor
Add a multi-stage Dockerfile to run go test (and optional -race) under Linux from macOS/Windows. Made-with: Cursor
Use the repository Dockerfile to build and run the 'test' and 'race' targets on every commit. Made-with: Cursor
Add TCP-based e2e tests covering basic CRUD and directory listing against both the ufs server and the synthetic file server (Fsrv). Made-with: Cursor
Add a Dockerfile that builds an upstream Linux kernel + initramfs, boots QEMU with a virtio-9p export, mounts it via the kernel 9p client, and runs a smoke-test binary. Made-with: Cursor
Parameterize the QEMU+kernel Docker harness for amd64/arm64 and add GitHub Actions jobs on ubuntu-latest and ubuntu-24.04-arm. Made-with: Cursor
Add an AI-generated Werner Herzog–style mirror of README.md plus a CI check to keep the section structure in sync. Made-with: Cursor
Document Docker targets, QEMU kernel 9p client smoke tests, multi-arch CI coverage, and reflect completed work in TODO/CHANGES. Made-with: Cursor
Update README.md (and HERZOG.md mirror) with copy-paste commands and sample output for running the ufs server and listing via the ls client. Made-with: Cursor
Mark recently completed README documentation items as done and keep the docs task list current. Made-with: Cursor
Add unit tests for malformed packets and size bounds. Harden gstr() to avoid panics on truncated string fields. Made-with: Cursor
Extend the QEMU kernel-client smoke test with symlinks, ENOENT checks, chmod/open behavior (best-effort), rename across directories, and best-effort xattr round-trips. Made-with: Cursor
Pin the kernel version in workflow env and use a per-arch, per-kernel-version BuildKit cache scope so kernel layers are reused across commits. Made-with: Cursor
Replace kernel.org tarball download with a shallow git checkout of the target kernel tag to avoid flaky curl fetches in CI. Made-with: Cursor
Support mounting the kernel 9p client against either QEMU virtio-9p or an external diod TCP server, and exercise both backends in CI. Made-with: Cursor
Support qemu virtio-9p, diod TCP, and u9fs (socat) TCP; pass server choice to the guest via kernel cmdline. Build u9fs from a pinned git commit in the test image and run all backends in CI (amd64/arm64). Made-with: Cursor
Set build-push-action platforms and docker run --platform to linux/${arch}
so amd64 and arm64 jobs do not load the wrong architecture under Buildx.
Also restore kernel9p matrix.server entries so KERNEL9P_SERVER is defined.
Made-with: Cursor
Run qemu/diod/u9fs smoke tests as separate steps after a single docker/build-push-action per matrix row (amd64 + arm64), reusing BuildKit GHA cache across commits. Made-with: Cursor
Add a v9fs/test kernel download stage and a kernel9p-test-v9fs target. In CI, arm64 uses the prebuilt kernel-main Image while amd64 continues building locally until a prebuilt bzImage is published. Add a go9p UFS server backend and run the kernel-client smoke test against both QEMU virtio-9p and go9p-ufs. Made-with: Cursor
Drop amd64 kernel-client coverage for now and always use the v9fs/test prebuilt kernel target in the kernel9p job. Made-with: Cursor
Produce initramfs.cpio alongside initramfs.cpio.gz and update the QEMU runner to use the uncompressed initramfs by default, improving compatibility with external prebuilt kernels. Made-with: Cursor
Default kernel9p-qemu CI to use v9fs/test release assets while letting workflow_dispatch override the kernel tag. Made-with: Cursor
Avoid go build failures when git metadata is unavailable or restricted inside the v9fs/docker container. Made-with: Cursor
Add tailored unit tests for each example 9P server and split kernel-client QEMU e2e into per-filesystem jobs, with a dedicated tlsramfs userspace stage. Also update the kernel mount smoke runner and docs for the new harness. Made-with: Cursor
Add overview READMEs for the example servers and clients and link them from the top-level README. Made-with: Cursor
Expand example documentation with internal structure notes for ramfs/timefs/clonefs/tlsramfs and a quick mental model for srv.File trees and client example flow. Made-with: Cursor
Document how to build and serve synthetic filesystems with p/srv, including common patterns like control files, clone allocators, and streaming nodes. Made-with: Cursor
Add a new server example implementing a minimal Plan 9-style /net/tcp conversation interface (clone/ctl/data/status/local/remote) backed by Linux TCP sockets, plus an end-to-end unit test and documentation. Made-with: Cursor
Replace the devnet TCP-only example with netfs, a broader Plan 9-style /net surface including a working /net/tcp conversation interface plus minimal stubs for ip(3) protocol directories, ipifc/ndb/log/ipselftab, and ether(3)/bridge(3) entry points. Made-with: Cursor
Document the netfs example in the top-level README and add broader netfs unit tests covering ndb limits, ipifc/ipselftab, ether0 type tracking, bridge ctl logging, and placeholder protocol directories. Made-with: Cursor
Remove the HERZOG.md heading sync check from GitHub Actions and keep the guidance in AGENTS.md instead. Made-with: Cursor
Include netfs in kernel9p-qemu and extend the guest harness/kernel smoke test to validate basic /net surfaces under both 9p2000 and 9p2000.u mounts. Made-with: Cursor
Document the netfs example's hierarchy, the TCP clone/ctl/data conversation model, and what is implemented vs stubbed. Made-with: Cursor
Add read-only error files in clone-allocated session directories (tcp and ether0) so Linux mounts can retrieve detailed last error strings after ctl write failures. Made-with: Cursor

This is a broader rework inclusive of the modernization changes from before. I'm trying to improve the testing framework, specifically against the synthetic file systems since those are our focus.
