bpf_flow.c: exit early unless BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG is passed in flags. Also, set ip_proto earlier, this makes sure we have correct value with fragmented packets. Add selftest cases to test ipv4/ipv6 fragments and skip eth_get_headlen tests that don't have BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG flag. eth_get_headlen calls flow dissector with BPF_FLOW_DISSECTOR_F_PARSE_1ST_FRAG flag so we can't run tests that have different set of input flags against it. v2: * sefltests -> selftests (Willem de Bruijn) * Reword a comment about eth_get_headlen flags (Song Liu) Acked-by: Petar Penkov <ppenkov@google.com> Acked-by: Willem de Bruijn <willemb@google.com> Acked-by: Song Liu <songliubraving@fb.com> Cc: Song Liu <songliubraving@fb.com> Cc: Willem de Bruijn <willemb@google.com> Cc: Petar Penkov <ppenkov@google.com> Signed-off-by: Stanislav Fomichev <sdf@google.com> 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.
