Formerly, a boolean denoting whether bpf_flow_dissect returned BPF_OK was set into 'bpf_attr.test.retval'. Augment this, so users can check the actual return code of the dissector program under test. Existing prog_tests/flow_dissector*.c tests were correspondingly changed to check against each test's expected retval. Also, tests' resulting 'flow_keys' are verified only in case the expected retval is BPF_OK. This allows adding new tests that expect non BPF_OK.

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.
