Add these generic helpers that may be useful to use from sk_msg programs. The helpers do not depend on ctx so we can simply add them here, BPF_FUNC_perf_event_output BPF_FUNC_get_current_uid_gid BPF_FUNC_get_current_pid_tgid BPF_FUNC_get_current_cgroup_id BPF_FUNC_get_current_ancestor_cgroup_id BPF_FUNC_get_cgroup_classid Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/bpf/159033903373.12355.15489763099696629346.stgit@john-Precision-5820-Tower Signed-off-by: Alexei Starovoitov <ast@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.
