The test_cgrp2_attach test covers bpf cgroup attachment code well, so let's re-use it for testing allocation/releasing of cgroup storage. The extension is pretty straightforward: the bpf program will use the cgroup storage to save the number of transmitted bytes. Expected output: $ ./test_cgrp2_attach2 Attached DROP prog. This ping in cgroup /foo should fail... ping: sendmsg: Operation not permitted Attached DROP prog. This ping in cgroup /foo/bar should fail... ping: sendmsg: Operation not permitted Attached PASS prog. This ping in cgroup /foo/bar should pass... Detached PASS from /foo/bar while DROP is attached to /foo. This ping in cgroup /foo/bar should fail... ping: sendmsg: Operation not permitted Attached PASS from /foo/bar and detached DROP from /foo. This ping in cgroup /foo/bar should pass... ### override:PASS ### multi:PASS Signed-off-by: Roman Gushchin <guro@fb.com> Cc: Alexei Starovoitov <ast@kernel.org> Cc: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
