2022-05-10selftests/bpf: Handle batch operations for map-in-map bpf-mapsTakshak Chahande
This patch adds up test cases that handles 4 combinations: a) outer map: BPF_MAP_TYPE_ARRAY_OF_MAPS inner maps: BPF_MAP_TYPE_ARRAY and BPF_MAP_TYPE_HASH b) outer map: BPF_MAP_TYPE_HASH_OF_MAPS inner maps: BPF_MAP_TYPE_ARRAY and BPF_MAP_TYPE_HASH Signed-off-by: Takshak Chahande <ctakshak@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Yonghong Song <yhs@fb.com> Link: https://lore.kernel.org/bpf/20220510082221.2390540-2-ctakshak@fb.com
2022-05-09selftests: clarify common error when running gup_testJoel Savitz
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. Add a short error message to clarify this failure and point the user to the solution.

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'. Stop. make[1]: Leaving directory '/root/linux/tools/testing/selftests/vm' make: *** [Makefile:175: all] Error 2 make: Leaving directory '/root/linux/tools/testing/selftests' The TARGETS variable passed to tools/testing/selftests/Makefile collides with the TARGETS used in tools/testing/selftests/vm/Makefile, so rename the latter to VMTARGETS, eliminating the collision with no functional change.

2022-05-09libbpf: Provide barrier() and barrier_var() in bpf_helpers.hAndrii Nakryiko
Add barrier() and barrier_var() macros into bpf_helpers.h to be used by end users. While a bit advanced and specialized instruments, they are sometimes indispensable. 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. Some tests rely on barrier_var() definition being nothing, those will still work as libbpf does the #ifndef/#endif guarding for barrier() and barrier_var(), allowing users to redefine them, if necessary.

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.

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>

2022-05-04selftests: 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.

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.

2022-05-04selftests: KVM: Test SYSTEM_SUSPEND PSCI callOliver Upton
Assert that the vCPU exits to userspace with KVM_SYSTEM_EVENT_SUSPEND if the guest calls PSCI SYSTEM_SUSPEND. Additionally, guarantee that the SMC32 and SMC64 flavors of this call are discoverable with the PSCI_FEATURES call.

Setting a vCPU's MP state to KVM_MP_STATE_STOPPED has the effect of powering off the vCPU. Rather than using the vCPU init feature flag, use the KVM_SET_MP_STATE ioctl to power off the target vCPU.

2022-05-03selftests: mptcp: ADD_ADDR echo test with missing userspace daemonMat Martineau
Check userspace PM behavior to ensure ADD_ADDR echoes are only sent when there is an active userspace daemon. If the daemon is restarting or hasn't loaded yet, the missing echo will cause the peer to retransmit the ADD_ADDR - and hopefully the daemon will be ready to receive it at that later time.

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.
