2022-05-11selftests: forwarding: tc_actions: allow mirred egress test to run on ↵Vladimir Oltean
non-offloaded h2 The host interfaces $h1 and $h2 don't have to be switchdev interfaces, but due to the fact that we pass $tcflags which may have the value of "skip_sw", we force $h2 to offload a drop rule for dst_ip, something which it may not be able to do. The selftest only wants to verify the hit count of this rule as a means of figuring out whether the packet was received, so remove the $tcflags for it and let it be done in software.

Furthermore, it is easy to generalize to other HW stats suites (for when such are added). Therefore, move the code to lib.sh, rewrite it to have the same interface as the other stats-collecting functions, and generalize to take the name of the HW stats suite to collect as an argument.

2022-05-05selftests: add ping test with ping_group_range tunedNicolas Dichtel
The 'ping' utility is able to manage two kind of sockets (raw or icmp), depending on the sysctl ping_group_range. By default, ping_group_range is set to '1 0', which forces ping to use an ip raw socket. Let's replay the ping tests by allowing 'ping' to use the ip icmp socket. After the previous patch, ipv4 tests results are the same with both kinds of socket. For ipv6, there are a lot a new failures (the previous patch fixes only two cases).

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.

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.

2022-05-04selftests: 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/seccomp: Don't call read() on TTY from background pgrpJann Horn
Since commit 92d25637a3a4 ("kselftest: signal all child processes"), tests are executed in background process groups. This means that trying to read from stdin now throws SIGTTIN when stdin is a TTY, which breaks some seccomp selftests that try to use read(0, NULL, 0) as a dummy syscall. The simplest way to fix that is probably to just use -1 instead of 0 as the dummy read()'s FD.

2022-04-28perf symbol: Update symbols__fixup_end()Namhyung Kim
Now arch-specific functions all do the same thing. When it fixes the symbol address it needs to check the boundary between the kernel image and modules. For the last symbol in the previous region, it cannot know the exact size as it's discarded already. Thus it just uses a small page size (4096) and rounds it up like the last symbol.
