Use whitelist instead of a blacklist and allow only a small set of fields that might be relevant in the context of flow dissector: * data * data_end * flow_keys This is required for the eth_get_headlen case where we have only a chunk of data to dissect (i.e. trying to read the other skb fields doesn't make sense). Note, that it is a breaking API change! However, we've provided flow_keys->n_proto as a substitute for skb->protocol; and there is no need to manually handle skb->vlan_present. So even if we break somebody, the migration is trivial. Unfortunately, we can't support eth_get_headlen use-case without those breaking changes.

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.
