2022-05-25KVM: selftests: x86: Fix test failure on arch lbr capable platformsYang Weijiang
On Arch LBR capable platforms, LBR_FMT in perf capability msr is 0x3f, so the last format test will fail. Use a true invalid format(0x30) for the test if it's running on these platforms. Opportunistically change the file name to reflect the tests actually carried out.

2022-05-20KVM: selftests: riscv: Improve unexpected guest trap handlingAnup Patel
Currently, we simply hang using "while (1) ;" upon any unexpected guest traps because the default guest trap handler is guest_hang(). The above approach is not useful to anyone because KVM selftests users will only see a hung application upon any unexpected guest trap. This patch improves unexpected guest trap handling for KVM RISC-V selftests by doing the following: 1) Return to host user-space 2) Dump VCPU registers 3) Die using TEST_ASSERT(0, ...)

2022-05-09selftests: vm: Makefile: rename TARGETS to VMTARGETSJoel Savitz
The tools/testing/selftests/vm/Makefile uses the variable TARGETS internally to generate a list of platform-specific binary build targets suffixed with _{32,64}. When building the selftests using its own Makefile directly, such as via the following command run in a kernel tree: One receives an error such as the following: make: Entering directory '/root/linux/tools/testing/selftests' make --no-builtin-rules ARCH=x86 -C ../../.. headers_install make[1]: Entering directory '/root/linux' INSTALL ./usr/include make[1]: Leaving directory '/root/linux' make[1]: Entering directory '/root/linux/tools/testing/selftests/vm' make[1]: *** No rule to make target 'vm.c', needed by '/root/linux/tools/testing/selftests/vm/vm_64'.

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.

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.

2022-05-03selftests: 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).

2022-04-29selftests/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.

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.
