Subject: [PATCH 0/4] Tests for overlayfs immutable/append-only files
Date: Sat, 16 Jan 2021 18:56:15 +0200	[thread overview]
Message-ID: <20210116165619.494265-1-amir73il@gmail.com> (raw)

Eryu,

Overlayfs never had full support for immutable/append-only files.
Whatever works is covered by generic/079 and overlay/030 tests.
Both tests cover only upper files and directories.
generic/079 is notrun on kernel < 5.10 and passes on >= 5.10.

This series improves the t_immutable test program and adds a new test
to cover lower files and directories - the test fails on upstream kernel.
Fixing this requires some VFS API changes that Miklos has proposed [1].

The new test covers two reported bug, one of them is a deadlock.
The deadlock trigger is commented out until we have a fix upstream.

Thanks,
Amir.
