[PATCH v10 5/9] kselftests: cgroup: don't fail on cg_kill_all() error in cg_destroy()

by Roman Gushchin

If the cgroup destruction races with an exit() of a belonging process(es), cg_kill_all() may fail. It's not a good reason to make cg_destroy() fail and leave the cgroup in place, potentially causing next test runs to fail.

[PATCH] selftests : netfilter: Wrote a error and exit code for a command which needed veth kernel module.

by Jeffrin Jose T

A test for the basic NAT functionality uses ip command which needs veth device.There is a condition where the kernel support for veth is not compiled into the kernel and the test script breaks.This patch contains code for reasonable error display and correct code exit.

[PATCH v3 0/7] lib/string: Add strscpy_pad() function

by Tobin C. Harding

Hi, strscpy_pad() patch set now with added test shenanigans. This version adds 5 initial patches to the set and splits the single patch from v2 into two separate patches (6 and 7). While doing the testing for strscpy_pad() it was noticed that there is duplication in how test modules are being fed to kselftest and also in the test modules themselves. This set makes an attempt at adding a framework to kselftest for writing kernel test modules. It also adds a script for use in creating script test runners for kselftest. My macro-foo is not great, all criticism and suggestions very much appreciated. The design is based on test modules lib/test_printf.c, lib/test_bitmap.c, lib/test_xarray.c. Shua, I'm by no means a kselftest expert, if this approach does not fit in with your general direction please say so. Kees, I put the strscpy_pad() addition patch separate so if this goes in through Shua's tree (and if it goes in at all) its a single patch to grab if we want to start playing around with strscpy_pad(). Patch 1 fixes module unload for lib/test_printf in preparation for the rest of the series. Patch 2 Adds a shell script that can be used to create shell script test runners. Patch 3 Converts current shell script runners in tools/testing/selftests/lib/ to use the script introduced in patch 2. Patch 4 Adds the test framework by way of a header file (inc. documentation) Patch 5 Converts a couple of current test modules to make some use of the newly added test framework. Patch 6 Adds strscpy_pad() Patch 7 Adds test module for strscpy_pad() using the new framework and script. If you are a testing geek and you would like to play with this; if you are already running a kernel built recently from your tree you may want to just apply the first 5 patches then you don't need to build/boot a new kernel, just config and build the lib/ test modules (test_printf etc.) and then: sudo make TARGETS=lib kselftest Late in the development of this I found that a bunch of boiler plate had to be added to the script to handle running tests with: make O=/path/to/kout kselftest The reason is that during the build we are in the output directory but the script is in the source directory. I get the feeling that a better understanding of how the kernel build process works would provide a better solution to this. The current solution is disappointing since removing duplication and boiler plate was the point of the whole exercise. I'd love a better way to solve this? One final interesting note: there are 36 test modules in lib/ only 3 of them are run by kselftest from tools/testing/selfests/lib? Thanks for looking at this, Tobin. Tobin C.

[PATCH v2 1/2] Provide in-kernel headers for making it easy to extend the kernel

by Joel Fernandes (Google)

Introduce in-kernel headers and other artifacts which are made available as an archive through proc (/proc/kheaders.txz file). This archive makes it possible to build kernel modules, run eBPF programs, and other tracing programs that need to extend the kernel for tracing purposes without any dependency on the file system having headers and build artifacts. On Android and embedded systems, it is common to switch kernels but not have kernel headers available on the file system. Raw kernel headers also cannot be copied into the filesystem like they can be on other distros, due to licensing and other issues. There's no linux-headers package on Android. Further once a different kernel is booted, any headers stored on the file system will no longer be useful. By storing the headers as a compressed archive within the kernel, we can avoid these issues that have been a hindrance for a long time. The feature is also buildable as a module just in case the user desires it not being part of the kernel image. This makes it possible to load and unload the headers on demand. A tracing program, or a kernel module builder can load the module, do its operations, and then unload the module to save kernel memory. The total memory needed is 3.8MB. The code to read the headers is based on /proc/config.gz code and uses the same technique to embed the headers. To build a module, the below steps have been tested on an x86 machine: modprobe kheaders rm -rf $HOME/headers mkdir -p $HOME/headers tar -xvf /proc/kheaders.txz -C $HOME/headers >/dev/null cd my-kernel-module make -C $HOME/headers M=$(pwd) modules rmmod kheaders Signed-off-by: Joel Fernandes (Google) <joel(a)joelfernandes.org> --- Changes since v1: - removed IKH_EXTRA variable, not needed (Masahiro Yamada) - small fix ups to selftest - added target to main Makefile etc - added MODULE_LICENSE to test module - made selftest more quiet Changes since RFC: Both changes bring size down to 3.8MB: - use xz for compression - strip comments except SPDX lines - Call out the module name in Kconfig - Also added selftests in second patch to ensure headers are always working.

[PATCH v3.1] selftests: Clean up module testing shell script

by Kees Cook

This adjusts kselftest_module.sh to take an option "args" argument for modprobe arguments, removes bash-isms (since some system's /bin/sh may not be bash), and refactors the lib/ scripts into a shorter calling convention.

[PATCH v15 6/6] selftests: media_dev_allocator api test

by Shuah Khan

Add a new test for Media Device Allocator API. Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. This test does a series of unbind/bind tests to make sure media device is released correctly when it is no longer is use and when the last driver releases the reference.
