Linux kernel source tree
22567590b2
Currently, the /proc/sys/net/bridge folder is only created in the initial network namespace. This patch ensures that the /proc/sys/net/bridge folder is available in each network namespace if the module is loaded and disappears from all network namespaces when the module is unloaded. In doing so the patch makes the sysctls: bridge-nf-call-arptables bridge-nf-call-ip6tables bridge-nf-call-iptables bridge-nf-filter-pppoe-tagged bridge-nf-filter-vlan-tagged bridge-nf-pass-vlan-input-dev apply per network namespace. This unblocks some use-cases where users would like to e.g. not do bridge filtering for bridges in a specific network namespace while doing so for bridges located in another network namespace. The netfilter rules are afaict already per network namespace so it should be safe for users to specify whether bridge devices inside a network namespace are supposed to go through iptables et al. or not. Also, this can already be done per-bridge by setting an option for each individual bridge via Netlink. It should also be possible to do this for all bridges in a network namespace via sysctls.

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.
