====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Harden set element field checks to avoid out-of-bound memory access,
   this patch also fixes the type of issue described in 7e6bc1f6ca
   ("netfilter: nf_tables: stricter validation of element data") in a
   broader way.

2) Patches to restrict the chain, set, and rule id lookup in the
   transaction to the corresponding top-level table, patches from
   Thadeu Lima de Souza Cascardo.

3) Fix incorrect comment in ip6t_LOG.h

4) nft_data_init() performs upfront validation of the expected data.
   struct nft_data_desc is used to describe the expected data to be
   received from userspace. The .size field represents the maximum size
   that can be stored, for bound checks. Then, .len is an input/output field
   which stores the expected length as input (this is optional, to restrict
   the checks), as output it stores the real length received from userspace
   (if it was not specified as input). This patch comes in response to
   7e6bc1f6ca ("netfilter: nf_tables: stricter validation of element data")
   to address this type of issue in a more generic way by avoid opencoded
   data validation. Next patch requires this as a dependency.

5) Disallow jump to implicit chain from set element, this configuration
   is invalid. Only allow jump to chain via immediate expression is
   supported at this stage.

6) Fix possible null-pointer derefence in the error path of table updates,
   if memory allocation of the transaction fails. From Florian Westphal.

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.
