Now what is the playbook, we have three options in order of preference:
- #ifdef MODULE use capable() to preserve API, add a short comment about
the side effects if overlayfs is used as a module.
- export has_capability_nodaudit (proc and oom_kill use it, and are both
built-in only), but affect the 3.18 API at near EOL. AFAIK no one wants that?
I'll just do this. 3.18 is EOL, this is only being done for a distro-specific tree (i.e. AOSP).
- Do nothing more. Make this a distro concern only. Leave this posted as a
back-port for the record, but never merged, for those that are _interested_ and declare 3.18 stable as noisy for sepolicy and overlayfs under some usage patterns with few user space mitigation unless they explicitly take this back-port into their tree (eg: android common kernel) if used built-in. This way, in 3.18.y at least the module and built-in version behave the _same_ in stable.
I'll just add the export to the patch and check this into AOSP, thanks!
