Description Javier Martinez Canillas 2023-05-30 10:59:41 UTC

Description of problem:

Enable the efofs filesystem kernel config option in the automotive kernel and backport its support for chunk-based file on-disk format. This is needed to have filesystem level verified boot.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Check that the CONFIG_EROFS_FS, CONFIG_EROFS_FS_POSIX_ACL, CONFIG_EROFS_FS_SECURITY and CONFIG_EROFS_FS_XATTR options are enabled in the kernel automotive config.
2. Create an erofs image using `mkfs.erofs --chunksize=2048 foo.erofs.img foo/` comamnd.
3. 

Actual results:

The mentioned options are not enabled.

Expected results:

The mentioned options are enabled and a erofs filesystem image using chunk-based files is supported.

Is there an associated Bugzilla for erofs-utils?

I am also curious about formal ownership of erofs in the automotive kernel - typically every subsystem in the RHEL kernel (at least those that are enabled) get an entry in https://gitlab.com/redhat/centos-stream/src/kernel/documentation/-/blob/main/info/owners.yaml to make it clear who the maintainers and reviewers are for any given subsystem.

If there are no more people helping on erofs-utils, is it possible to land
erofs-utils into EPEL?
I could help maintain it as an external community user anyway if needed.

Anyway, it's only a suggestion on my side.

Thanks,
