2022-05-23selftests/landlock: Make tests build with old libcMickaël Salaün
Replace SYS_<syscall> with __NR_<syscall>. Using the __NR_<syscall> notation, provided by UAPI, is useful to build tests on systems without the SYS_<syscall> definitions. Replace SYS_pivot_root with __NR_pivot_root, and SYS_move_mount with __NR_move_mount. Define renameat2() and RENAME_EXCHANGE if they are unknown to old build systems.

2022-05-22selftests: ocelot: tc_flower_chains: reorder interfacesVladimir Oltean
Use the standard interface order h1, swp1, swp2, h2 that is used by the forwarding selftest framework. The previous order was confusing even with the ASCII drawing. That isn't needed anymore. This also drops the fixed MAC addresses and uses STABLE_MAC_ADDRS, which ensures the MAC addresses are unique. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

Commit 3752e453f6ba ("selftests/powerpc: Add tests of PMU EBBs") added selftest testcases to verify EBB interface. instruction_count_test.c testcase needs a fixed loop function to count overhead. Instead of using the thirty_two_instruction_loop() in fixed_instruction_loop.S in ebb folder, file is linked with thirty_two_instruction_loop() in loop.S from top folder.

2022-05-22selftests/powerpc: Better reporting in spectre_v2Russell Currey
In commit f3054ffd71b5 ("selftests/powerpc: Return skip code for spectre_v2"), the spectre_v2 selftest is updated to be aware of cases where the vulnerability status reported in sysfs is incorrect, skipping the test instead. This happens because qemu can misrepresent the mitigation status of the host to the guest. If the count cache is disabled in the host, and this is correctly reported to the guest, then the guest won't apply mitigations. If the guest is then migrated to a new host where mitigations are necessary, it is now vulnerable because it has not applied mitigations. Update the selftest to report when we see excessive misses, indicative of the count cache being disabled. If software flushing is enabled, also warn that these flushes are just wasting performance.

2022-05-20selftests: Add test for timing a bind request to a port with a populated ↵Joanne Koong
bhash entry This test populates the bhash table for a given port with MAX_THREADS * MAX_CONNECTIONS sockets, and then times how long a bind request on the port takes. When populating the bhash table, we create the sockets and then bind the sockets to the same address and port (SO_REUSEADDR and SO_REUSEPORT are set). When timing how long a bind on the port takes, we bind on a different address without SO_REUSEPORT set. We do not set SO_REUSEPORT because we are interested in the case where the bind request does not go through the tb->fastreuseport path, which is fragile (eg tb->fastreuseport path does not work if binding with a different uid). To run the test locally, I did: * ulimit -n 65535000 * ip addr add 2001:0db8:0:f101::1 dev eth0 * ./bind_bhash_test 443 Signed-off-by: Joanne Koong <joannelkoong@gmail.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Commit 49bb39bddad2 ("selftests: fib_nexthops: Make the test more robust") increased the timeout of ping commands to 5 seconds, to make the test more robust. Make the timeout configurable using '-w' argument to allow user to change it depending on the system that runs the test. Some systems suffer from slow forwarding performance, so they may need to change the timeout.

2022-05-16kunit: tool: Add list of all valid test configs on UMLDavid Gow
It's often desirable (particularly in test automation) to run as many tests as possible. This config enables all the tests which work as builtins under UML at present, increasing the total tests run from 156 to 342 (not counting 36 'skipped' tests). They can be run with: ./tools/testing/kunit/kunit.py run --kunitconfig=./tools/testing/kunit/configs/all_tests_uml.config This acts as an in-between point between the KUNIT_ALL_TESTS config (which enables only tests whose dependencies are already enabled), and the kunit_tool --alltests option, which tries to use allyesconfig, taking a very long time to build and breaking very often.
