Yue Haibing 7816b60922 ipv6: Add sanity checks on ipv6_devconf.rpl_seg_enabled
[ Upstream commit 3d95261eeb74958cd496e1875684827dc5d028cc ]

In ipv6_rpl_srh_rcv() we use min(net->ipv6.devconf_all->rpl_seg_enabled,
idev->cnf.rpl_seg_enabled) is intended to return 0 when either value is
zero, but if one of the values is negative it will in fact return non-zero.

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.
