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.

2022-05-04selftests: mlxsw: bail_on_lldpad before installing the cleanup trapPetr Machata
A number of mlxsw-specific QoS tests use manual QoS DCB management. As such, they need to make sure lldpad is not running, because it would override the configuration the test has applied using other tools. To that end, these selftests invoke the bail_on_lldpad() helper, which terminates the selftest if th lldpad is running. Some of these tests however first install the bash exit trap, which invokes a cleanup() at the test exit. If bail_on_lldpad() has terminated the script even before the setup part was run, the cleanup part will be very confused. Therefore make sure bail_on_lldpad() is invoked before the cleanup is registered. While there are still edge cases where the user terminates the script before the setup was fully done, this takes care of a common situation where the cleanup would be invoked in an inconsistent state.

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).

2022-05-02selftests: forwarding: add Per-Stream Filtering and Policing test for OcelotVladimir Oltean
The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action which enforced time-based access control per stream. A stream as seen by this switch is identified by {MAC DA, VID}. We use the standard forwarding selftest topology with 2 host interfaces and 2 switch interfaces. The host ports must require timestamping non-IP packets and supporting tc-etf offload, for isochron to work. The isochron program monitors network sync status (ptp4l, phc2sys) and deterministically transmits packets to the switch such that the tc-gate action either (a) always accepts them based on its schedule, or (b) always drops them. I tried to keep as much of the logic that isn't specific to the NXP LS1028A in a new tsn_lib.sh, for future reuse. This covers synchronization using ptp4l and phc2sys, and isochron. The cycle-time chosen for this selftest isn't particularly impressive (and the focus is the functionality of the switch), but I didn't really know what to do better, considering that it will mostly be run during debugging sessions, various kernel bloatware would be enabled, like lockdep, KASAN, etc, and we certainly can't run any races with those on. I tried to look through the kselftest framework for other real time applications and didn't really find any, so I'm not sure how better to prepare the environment in case we want to go for a lower cycle time. At the moment, the only thing the selftest is ensuring is that dynamic frequency scaling is disabled on the CPU that isochron runs on. It would probably be useful to have a blacklist of kernel config options (checked through zcat /proc/config.gz) and some cyclictest scripts to run beforehand, but I saw none of those.

2022-04-29selftests: mptcp: Add tests for userspace PM typeMat Martineau
These tests ensure that the in-kernel path manager is bypassed when the userspace path manager is configured. Kernel code is still responsible for ADD_ADDR echo, so also make sure that's working.

2022-04-29selftests: cgroup: fix alloc_anon_noexit() instantly freeing memoryYosry Ahmed
Currently, alloc_anon_noexit() calls alloc_anon() which instantly frees the allocated memory. alloc_anon_noexit() is usually used with cg_run_nowait() to run a process in the background that allocates memory. It makes sense for the background process to keep the memory allocated and not instantly free it (otherwise there is no point of running it in the background).

2022-04-29selftests/seccomp: Ensure that notifications come in FIFO orderSargun Dhillon
When multiple notifications are waiting, ensure they show up in order, as defined by the (predictable) seccomp notification ID. This ensures FIFO ordering of notification delivery as notification ids are monitonic and decided when the notification is generated (as opposed to received).

Running the seccomp tests under the kernel with "defconfig" shouldn't fail. Because the CONFIG_USER_NS is not supported in "defconfig". Skipping this case instead of failing it is better.
