PPPoEject — Linux kernel PPPoE use-after-free tracking site

Source for the PPPoEject patch-status tracker: a single-page site recording which distributions have shipped a fix for the PPPoE sendmsg() stale skb-head use-after-free in the Linux kernel.

Where the facts live

Everything about the bug — the CVE ID, affected and fixed versions, upstream fix commits, discovery and disclosure credit, and current per-distribution patch status — belongs to the tracker page, not to this README:

• Rendered: https://kimmo.cloud/pppoeject/
• Source: site/content/_index.md

Edit that file; everything else in this repo is build infrastructure.

None of it is restated here on purpose. The tracker page is revised as distributions ship fixes — for the actively updated trackers, daily by the auto-update agent — so any copy kept in this README would silently rot. Resist re-adding a summary.

Deployment plan and current setup state live in WEBSITE.md.

Local development

Requires Hugo ≥ 0.146.0 (the standard edition suffices: no Sass or image processing in this site) and Go (for Hugo Modules to fetch the PaperMod theme).

With Nix (recommended)

nix develop          # dev shell: hugo, go, resvg + fonts, and every lookup tool
cd site
hugo server          # local preview at http://localhost:1313/pppoeject/

If you use direnv, direnv allow once and the dev shell auto-activates whenever you cd into the repo.

Without Nix

Install Hugo ≥ 0.146.0 and Go ≥ 1.24 yourself (CLAUDE.md § "Build environment" has the go install recipe), then:

cd site
hugo server          # http://localhost:1313/pppoeject/

Build and publish

make build       # local build into site/public/
make dist        # build, then rsync to haig:/pppoeject/
make banner      # re-rasterise the social banner SVG → PNG (needs resvg + the banner fonts)

make dist runs make build first. make banner is only needed after editing site/assets/pppoeject-tracker.svg; the rendered PNG is committed.
