2022-05-11selftests: xsk: add timeout to testsMagnus Karlsson
Add a timeout to the tests so that if all packets have not been received within 3 seconds, fail the ongoing test. Hinders a test from dead-locking if there is something wrong.

2022-05-11selftests: xsk: fix reporting of failed testsMagnus Karlsson
Fix the reporting of failed tests as it was broken in several ways. First, a failed test was reported as both failed and passed messing up the count. Second, tests were not aborted after a failure and could generate more "failures" messing up the count even more. Third, the failure reporting from the application to the shell script was wrong. It always reported pass. And finally, the handling of the failures in the launch script was not correct. Correct all this by propagating the failure up through the function calls to a calling function that can abort the test. A receiver or sender thread will mark the new variable in the test spec called fail, if a test has failed. This is then picked up by the main thread when everyone else has exited and this is then marked and propagated up to the calling script. Also add a summary function in the calling script so that a user does not have to go through the sub tests to see if something has failed.

2022-05-11selftests: xsk: do not send zero-length packetsMagnus Karlsson
Do not try to send packets of zero length since they are dropped by veth after commit 726e2c5929de84 ("veth: Ensure eth header is in skb's linear part"). Replace these two packets with packets of length 60 so that they are not dropped. Also clean up the confusing naming. MIN_PKT_SIZE was really MIN_ETH_PKT_SIZE and PKT_SIZE was both MIN_ETH_SIZE and the default packet size called just PKT_SIZE. Make it consistent by using the right define in the right place.

The gup_test binary will fail showing only the output of perror("open") in the case that /sys/kernel/debug/gup_test is not found. This will almost always be due to CONFIG_GUP_TEST not being set, which enables compilation of a kernel that provides this file.

Instead of requiring each user to figure out exact asm volatile incantations for themselves, provide them from bpf_helpers.h. Also remove conflicting definitions from selftests.

2022-05-04selftests: ocelot: tc_flower_chains: specify conform-exceed action for policerVladimir Oltean
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.

When moving to non-system toolchains, we inadvertantly killed the ability to use ccache. So instead, build ccache support into the test harness directly. Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.

This change updates the "pm_nl_ctl" testing sample with a "listen" option to bind a MPTCP listening socket to the provided addr+port. This option is exercised in testing subflow initiation scenarios in conjunction with userspace path managers where the MPTCP application does not hold an active listener to accept requests for new subflows.

This change adds to self-testing support for the MPTCP netlink interface by capturing various MPTCP netlink events (and all their metadata) associated with connections, subflows and address announcements. It is used in self-testing scripts that exercise MPTCP netlink commands to precisely validate those operations by examining the dispatched MPTCP netlink events in response to those commands.
