Commitfcb41decf6("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.
