2022-05-19tools/thermal: Add thermal daemon skeletonDaniel Lezcano
This change provides a simple daemon skeleton. It is an example of how to use the thermal library which wraps all the complex code related to the netlink and transforms it into a callback oriented code. The goal of this skeleton is to give a base brick for anyone interested in writing its own thermal engine or as an example to rely on to write its own thermal monitoring implementation. In the future, it will evolve with more features and hopefully more logic.

2022-05-19tools/thermal: Add a temperature capture toolDaniel Lezcano
The 'thermometer' tool allows to capture the temperature of a set of thermal zones defined in a configuration file at a specified rate. It is designed to have the lowest possible overhead. It will write the captured temperature per thermal zone per file so making easier to write a gnuplot script.

2022-05-19tools/lib/thermal: Add a thermal libraryDaniel Lezcano
The thermal framework implements a netlink notification mechanism to be used by the userspace to have a thermal configuration discovery, trip point changes or violation, cooling device changes notifications, etc... This library provides a level of abstraction for the thermal netlink notification allowing the userspace to connect to the notification mechanism more easily. The library is callback oriented.

2022-05-16kselftest/arm64: bti: force static linkingAndre Przywara
The "bti" selftests are built with -nostdlib, which apparently automatically creates a statically linked binary, which is what we want and need for BTI (to avoid interactions with the dynamic linker). However this is not true when building a PIE binary, which some toolchains (Ubuntu) configure as the default. When compiling btitest with such a toolchain, it will create a dynamically linked binary, which will probably fail some tests, as the dynamic linker might not support BTI: =================== TAP version 13 1..18 not ok 1 nohint_func/call_using_br_x0 not ok 2 nohint_func/call_using_br_x16 not ok 3 nohint_func/call_using_blr .... =================== To make sure we create static binaries, add an explicit -static on the linker command line. This forces static linking even if the toolchain defaults to PIE builds, and fixes btitest runs on BTI enabled machines.

2022-05-08perf tests: Fix coresight `perf test` failure.Jeremy Linton
Currently the `perf test` always fails the coresight test like: 89: Check Arm CoreSight trace data recording and synthesized samples: FAILED! That is because the test_arm_coresight.sh is attempting to SIGINT the parent but is using $$ rather than $PPID and it sigint's itself when run under the perf test framework. Since this is done in a trap clause it ends up returning a non zero return. Since $PPID is a bash ism and not all distros are linking /bin/sh to bash, the alternative parent pid lookups are uglier than just dropping the kill, and its not strictly needed, lets pick the simple solution and drop the sigint.

As discussed here with Ido Schimmel: https://patchwork.kernel.org/project/netdevbpf/patch/20220224102908.5255-2-jianbol@nvidia.com/ the default conform-exceed action is "reclassify", for a reason we don't really understand. The point is that hardware can't offload that police action, so not specifying "conform-exceed" was always wrong, even though the command used to work in hardware (but not in software) until the kernel started adding validation for it. Fix the command used by the selftest by making the policer drop on exceed, and pass the packet to the next action (goto) on conform.

2022-05-04wireguard: selftests: use newer toolchains to fill out architecturesJason A. Donenfeld
Rather than relying on the system to have cross toolchains available, simply download musl.cc's ones and use that libc.so, and then we use it to fill in a few missing platforms, such as riscv64, riscv64, powerpc64, and s390x. Since riscv doesn't have a second serial port in its device description, we have to use virtio's vport. This is actually the same situation on ARM, but we were previously hacking QEMU up to work around this, which required a custom QEMU. Instead just do the vport trick on ARM too.

2022-05-04wireguard: selftests: limit parallelism to $(nproc) tests at onceJason A. Donenfeld
The parallel tests were added to catch queueing issues from multiple cores. But what happens in reality when testing tons of processes is that these separate threads wind up fighting with the scheduler, and we wind up with contention in places we don't care about that decrease the chances of hitting a bug. So just do a test with the number of CPU cores, rather than trying to scale up arbitrarily. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-05-04wireguard: selftests: make routing loop test non-fatalJason A. Donenfeld
I hate to do this, but I still do not have a good solution to actually fix this bug across architectures. So just disable it for now, so that the CI can still deliver actionable results. This commit adds a large red warning, so that at least the failure isn't lost forever, and hopefully this can be revisited down the line.

Currently the arm64 kselftests attempt to locate the ABI headers using custom logic which doesn't work correctly in the case of out of tree builds if KBUILD_OUTPUT is not specified. Since lib.mk defines KHDR_INCLUDES with the appropriate flags we can simply remove the custom logic and use that instead.

2022-05-03selftests/seccomp: Add test for wait killable notifierSargun Dhillon
This verifies that if a filter is set up with the wait killable feature that it obeys the semantics that non-fatal signals are ignored during a notification after the notification is received. Cases tested: * Non-fatal signal prior to receive * Non-fatal signal during receive * Fatal signal after receive The normal signal handling is tested in user_notification_signal. That behaviour remains unchanged. On an unsupported kernel, these tests will immediately bail as it relies on a new seccomp flag.

2022-05-03selftests: mirror_gre_bridge_1q: Avoid changing PVID while interface is ↵Ido Schimmel
operational In emulated environments, the bridge ports enslaved to br1 get a carrier before changing br1's PVID. This means that by the time the PVID is changed, br1 is already operational and configured with an IPv6 link-local address. When the test is run with netdevs registered by mlxsw, changing the PVID is vetoed, as changing the VID associated with an existing L3 interface is forbidden. This restriction is similar to the 8021q driver's restriction of changing the VID of an existing interface. Fix this by taking br1 down and bringing it back up when it is fully configured. With this fix, the test reliably passes on top of both the SW and HW data paths (emulated or not).
