====================
This patch series fixes the existing BPF flow dissector API to
support calling BPF progs from the eth_get_headlen context (the
support itself will be added in bpf-next tree).
The summary of the changes:
* fix VLAN handling in bpf_flow.c, we don't need to peek back and look
at skb->vlan_present; add selftests
* pass and use flow_keys->n_proto instead of skb->protocol
* fix clamping of flow_keys->nhoff for packets with nhoff > 0
* prohibit access to most of the __sk_buff fields from BPF flow
dissector progs; only data/data_end/flow_keys are allowed (all input
is now passed via flow_keys)
* finally, document BPF flow dissector program environment

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.
