Felix Maurer 755d4b7440 selftests: bpf: Check bpf_msg_push_data return value commit `61d06f01f9` upstream. bpf_msg_push_data may return a non-zero value to indicate an error. The return value should be checked to prevent undetected errors. To indicate an error, the BPF programs now perform a different action than their intended one to make the userspace test program notice the error, i.e., the programs supposed to pass/redirect drop, the program supposed to drop passes. Fixes: `84fbfe026a` ("bpf: test_sockmap add options to use msg_push_data") Signed-off-by: Felix Maurer <fmaurer@redhat.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: John Fastabend <john.fastabend@gmail.com> Link: https://lore.kernel.org/bpf/89f767bb44005d6b4dd1f42038c438f76b3ebfad.1644601294.git.fmaurer@redhat.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2022-03-02 11:47:55 +01:00

README

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.
