Highlights

  • Added real user-namespace ID mapping paths, including procfs map files and UID/GID translation needed by container runtimes.
  • Improved PID and IPC namespace visibility through /proc, including namespace-file access required by docker exec.
  • Added a vendored overlayfs implementation adapted across Android GKI kernels from 5.10 through 6.12.
  • Improved namespace cleanup and container reboot routing, and fixed multiple module-load, CFI, IPC-lifecycle, and cross-KMI compatibility issues.

Compatibility

Release assets are available for arm64 Android GKI KMIs: android12-5.10, android13-5.10, android13-5.15, android14-5.15, android14-6.1, android15-6.6, and android16-6.12. Load only the module built for the device’s exact KMI. Network namespace isolation is not provided; use host networking. Overlay mounts may fail on casefold-capable backing filesystems.

Changes

feature:

  • Add user-namespace ID mapping and improve PID/IPC namespace access for container runtimes.
  • Vendor overlayfs with compatibility support across the seven release-build KMIs.

fix:

  • Fix namespace and IPC teardown issues, container reboot routing, and several KMI-specific load/runtime failures.

docs:

  • Document overlayfs backing-filesystem limitations and the supported behavior of namespace/procfs paths.

chore:

  • Expand per-KMI build and QEMU testing; improve the QEMU harness’s USB-device readiness and container tests.
