[ Upstream commitbcc3f2a829] I see no reason why max_dst_opts_cnt and max_hbh_opts_cnt are fetched from the initial net namespace. The other sysctls (max_dst_opts_len & max_hbh_opts_len) are in fact already using the current ns. Note: it is not clear why ipv6_destopt_rcv() use two ways to get to the netns : 1) dev_net(dst->dev) Originally used to increment IPSTATS_MIB_INHDRERRORS 2) dev_net(skb->dev) Tom used this variant in his patch. Maybe this calls to use ipv6_skb_net() instead ?

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.
