Florian Westphal says: ==================== v4: address comment from Daniel Xu: - use human-readable test names in 2/2 v3: address comments from Andrii: - prune verbose error message in 1/2 - use bpf_link_create internally in 1/2 - use subtests in patch 2/2 When initial netfilter bpf program type support got added one suggestion was to extend libbpf with a helper to ease attachment of nf programs to the hook locations. Add such a helper and a demo test case that attaches a dummy program to various combinations. I tested that the selftest fails when changing the expected outcome (i.e., set 'success' when it should fail and v.v.). ==================== Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
