SPDX-License-Identifier: GPL-2.0 + +Kernel hacking Debian image +=========================== + +The :doc:`OpenWrt image <OpenWrt_in_QEMU>` is an easy way to start multiple +virtual instances. But these instances usually don��t provide the +required infrastructure to test kernel modules extensively. And it also +depends on special toolchains to prepare the used tools/modules which +should tested. + +It is often easier to use the same operating system in the virtual +environment and on the host. Only the kernel is modified here to provide +the necessary helpers for in-kernel development. + +An interested reader might even extend this further to only provide a +modified kernel and use the currently running rootfs also in the virtual +environment. Such an approach is used in `hostap��s test +vm <https://w1.fi/cgit/hostap/tree/tests/hwsim/vm>`__ but it is out of +scope for this document. + +Create an Image +--------------- + +The debian root filesystem is used here to a minimal system to boot and +run the test programs.

Repository : ssh://git@diktynna/batman-adv On branch : master >--------------------------------------------------------------- commit 43f49a32f714f1bfa2d7593dafe1a309976833cc Author: Sven Eckelmann <sven(a)narfation.org> Date: Mon Aug 17 14:37:13 2020 +0200 batman-adv: Drop legacy code for auto deleting mesh interfaces The only way to automatically drop batadv mesh interfaces when all soft interfaces were removed was dropped with the sysfs support. It is no longer needed to have them handled by kernel anymore.
