This patch adds tests for the new bpf tcp header option feature. test_tcp_hdr_options.c: - It tests header option writing and parsing in 3WHS: regular connection establishment, fastopen, and syncookie. - In syncookie, the passive side's bpf prog is asking the active side to resend its bpf header option by specifying a RESEND bit in the outgoing SYNACK. handle_active_estab() and write_nodata_opt() has some details. - handle_passive_estab() has comments on fastopen. - It also has test for header writing and parsing in FIN packet. - Most of the tests is writing an experimental option 254 with magic 0xeB9F. - The no_exprm_estab() also tests writing a regular TCP option without any magic. test_misc_tcp_options.c: - It is an one directional test. Active side writes option and passive side parses option. The focus is to exercise the new helpers and API. - Testing the new helper: bpf_load_hdr_opt() and bpf_store_hdr_opt(). - Testing the bpf_getsockopt(TCP_BPF_SYN). - Negative tests for the above helpers. - Testing the sock_ops->skb_data.

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.
