Fluxheim 1.7.11 Release Notes

Fluxheim 1.7.11 delivers the zero-downtime process-upgrade slice after the
stable 1.7 Wasm policy milestones. It combines bounded native drain, strict
listener inheritance, readiness-gated handoff, and tested native and Podman
deployment patterns.

The release also completes the native HTTP/1 parser audit and tightens critical
background-service ownership without changing operator configuration defaults.

Added

  • Track accepted native HTTP, HTTPS, HTTP/2, and Unix-listener connections so
    shutdown stops new accepts while established connections drain.
  • Apply server.process.grace_period_seconds and
    server.process.graceful_shutdown_timeout_seconds in the native runtime.
  • Add live regressions for keep-alive drain behavior and bounded shutdown.
  • Add a real-binary SIGTERM smoke to the maintained native HTTP/1 gate and
    human test launcher.
  • Document the native binary, systemd socket-activation, and Podman blue/green
    handoff boundaries before exposing upgrade automation.
  • Adopt public HTTP/HTTPS TCP listeners from the standard systemd FD-3
    protocol, requiring a matching LISTEN_PID, bounded descriptor count, and
    exact one-for-one launch-plan address match.
  • Add unit coverage for malformed activation metadata and real-socket adoption,
    plus a real-binary smoke that serves through an inherited listener and proves
    malformed activation fails closed.
  • Report systemd readiness only after native listener/background-service startup
    completes, fail startup if a configured notification socket is unreachable,
    and report bounded-drain status after a shutdown signal.
  • Exercise an old and new Fluxheim process on one parent-owned listener. The
    maintained smoke proves a bad replacement leaves old serving, green readiness
    precedes drain, established old traffic completes, and new requests have no
    connection-refusal window.
  • Ship an optional RPM/systemd socket unit for the packaged port-80 listener.
    It remains disabled by default so existing direct-binding deployments do not
    change behavior during package installation.
  • Add a real rootless-Podman blue/green smoke. It verifies that direct published
    ports cannot be atomically replaced, then proves the supported stable-front
    pattern with failed-green rollback and old keep-alive drain.
  • Wait for every configured background service to reach its explicit ready
    point before systemd receives READY=1; a service that exits first makes the
    replacement fail closed and leaves the old generation serving.
  • Reject inherited descriptors that are not listening TCP sockets, including a
    live regression using a connected stream bound to the expected address.
  • Defer public/admin accept loops until background readiness succeeds, and add
    a live late-failure replacement test proving the old generation serves every
    request while the replacement aborts.
  • Explicitly abort outstanding listener and background tasks at the drain
    timeout instead of relying on whole-process teardown.
  • Remove listenfd from socket activation and receive descriptors through a
    focused Fluxheim crate with environment clearing disabled, preserving memory
    safety for multithreaded and embedded runtimes.
  • Claim inherited systemd descriptors exactly once per process and own the
    complete set before validating any item. Concurrent calls and retries fail
    before touching FD 3, while validation failures close the complete set.

Fixed

  • Use one validated HTTP/1 authority for routing, authorization, forwarding,
    and cache partitioning. Conflicting absolute-form authority and Host,
    malformed ports/IPv6/host syntax, non-HTTP absolute targets, and malformed
    absolute URIs now fail before request dispatch.
  • Reject every HTTP/1.0 Transfer-Encoding message before evaluating
    keep-alive. Chunked decoding now bounds encoded bytes, line length, extension
    bytes, and chunk count, validates extension grammar, streams decoded data into
    caller-owned output, and preserves identical parser results across every
    fragmented-read boundary, including a split terminal CRLF at the line limit.
  • Return only a semantically validated public HTTP/1 request-head type. Host and
    authority agreement, request-target grammar, body framing, and persistence
    are resolved before callers can inspect or route a request.
  • Enforce the RFC 3986 ASCII path/query grammar and reject malformed raw or
    percent-encoded target characters before routing.
  • Reject origin response status codes outside 100..=599, oversized PROXY v1
    lines, and PROXY v2 payloads that exceed policy or differ from the declared
    frame length.
  • Prevent construction of unvalidated protocol headers, share one bounded
    Connection option parser with hop-by-hop filtering, and add dedicated fuzz
    targets for HTTP/1 request/response heads, request targets, chunk bodies, and
    PROXY v1/v2 frames.
  • Route HTTP/2 requests exclusively by :authority; supplied Host fields are
    replaced and requests without authority fail closed.
  • Remove all fixed and Connection-nominated hop-by-hop origin response
    headers before delivery or cache admission, and reject malformed options.
  • Read through at most eight HTTP/1 informational origin responses to the final
    response, reject generic status 101, and reject transfer-coding chains that
    Fluxheim cannot decode completely.
  • Prevent oversized embedded HTTP/1 connection limits from reaching Tokio's
    panicking semaphore constructor.
  • Accept only ownership-checked critical task handles in the runtime watchdog.
    Attempted noncritical registration returns the original live handle instead
    of dropping it and cancelling cache, metrics, certificate, or maintenance
    services.
  • Stop accepting caller-controlled executable and temporary-root paths in the
    zero-downtime and Podman blue/green smoke helpers. Their executable and
    secure workspace locations are now derived from fixed repository paths and
    Python-managed mode-0700 temporary directories, resolving the associated
    CodeQL command/path alerts.
  • Poll the final SWR disk-cache assertion for a bounded interval so the smoke
    observes the supported asynchronous memory-publish/disk-persistence order
    without masking a disk-store failure.

Build And Packaging

  • Pin the source, container build images, and RPM build prerequisite to the
    Rust 1.97 toolchain line.
  • Include the disabled-by-default fluxheim.socket systemd unit in the RPM
    payload alongside the documented activation workflow.
  • Update the interactive RPM build menu to Fedora 44 and openSUSE Leap 16.0,
    removing the end-of-life openSUSE Leap 15 target.
