Jakub Kicinski 166cf43070 net/neighbor: clear error in case strict check is not set 
[ Upstream commit 0de6a472c3 ]

Commit 51183d233b ("net/neighbor: Update neigh_dump_info for strict
data checking") added strict checking. The err variable is not cleared,
so if we find no table to dump we will return the validation error even
if user did not want strict checking.

I think the only way to hit this is to send an buggy request, and ask
for a table which doesn't exist, so there's no point treating this
as a real fix. I only noticed it because a syzbot repro depended on it
to trigger another bug.

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 reStructuredText 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.
