HsiuWen Yen d344591e72 netfilter: fix crash in flow offload by adding netns support
Commit fcb41decf6c6 ("config: enable some useful features on
!SMALL_FLASH devices") enabled netns, which in turn lead to the crash in
the flow offload target.

When the flow offloading framework intends to delete a flow from the
hardware table, it is necessary to retrieve the namespace from
nf_flowtable->ft_net. However, no one ever wrote the namespace into
nf_flowtable->ft_net in advance. So the framework will mistakenly use a
NULL namespace to execute dev_get_by_index_rcu(net, ifindex), leading to
the kernel panic.

 -----------------------------------------------------

This is the buildsystem for the OpenWrt Linux distribution.

To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.

You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.

1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default

2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/

3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.

4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
