2022-02-23selftests: Add and export a kernel uapi headers pathMuhammad Usama Anjum1-0/+4
Kernel uapi headers can be present at different paths depending upon how the build was invoked. It becomes impossible for the tests to include the correct headers directory. Set and export KHDR_INCLUDES variable to make it possible for sub make files to include the header files.

2022-02-23selftests: set the BUILD variable to absolute pathMuhammad Usama Anjum1-9/+17
The build of kselftests fails if relative path is specified through KBUILD_OUTPUT or O=<path> method. BUILD variable is used to determine the path of the output objects. When make is run from other directories with relative paths, the exact path of the build objects is ambiguous and build fails. make[1]: Entering directory '/home/usama/repos/kernel/linux_mainline2/tools/testing/selftests/alsa' gcc mixer-test.c -L/usr/lib/x86_64-linux-gnu -lasound -o build/kselftest/alsa/mixer-test /usr/bin/ld: cannot open output file build/kselftest/alsa/mixer-test Set the BUILD variable to the absolute path of the output directory.

If only futex selftest is compiled, uapi header files are copied to the selftests/futex/functional directory. This copy isn't needed. Set the DEFAULT_INSTALL_HDR_PATH variable to 1 to use the default header install path only. This removes extra copy of header file.

2022-02-23selftests/kselftest/runner.sh: Pass optional command parameters in environmentCristian Marussi1-1/+29
Some testcases allow for optional commandline parameters but as of now there is now way to provide such arguments to the runner script. Add support to retrieve such optional command parameters fron environment variables named so as to include the all-uppercase test executable name, sanitized substituting any non-acceptable varname characters with "_", following the pattern: KSELFTEST_<UPPERCASE_SANITIZED_TEST_NAME>_ARGS="options" Optional command parameters support is not available if 'tr' is not installed on the test system.

2022-02-23livepatch: Skip livepatch tests if ftrace cannot be configuredDavid Vernet2-4/+21
livepatch has a set of selftests that are used to validate the behavior of the livepatching subsystem. One of the testcases in the livepatch testsuite is test-ftrace.sh, which among other things, validates that livepatching gracefully fails when ftrace is disabled. In the event that ftrace cannot be disabled using 'sysctl kernel.ftrace_enabled=0', the test will fail later due to it unexpectedly successfully loading the test_klp_livepatch module. While the livepatch selftests are careful to remove any of the livepatch test modules between testcases to avoid this situation, ftrace may still fail to be disabled if another trace is active on the system that was enabled with FTRACE_OPS_FL_PERMANENT. For example, any active BPF programs that use trampolines will cause this test to fail due to the trampoline being implemented with register_ftrace_direct(). The following is an example of such a trace: tcp_drop (1) R I D tramp: ftrace_regs_caller+0x0/0x58 (call_direct_funcs+0x0/0x30) direct-->bpf_trampoline_6442550536_0+0x0/0x1000 In order to make the test more resilient to system state that is out of its control, this patch updates set_ftrace_enabled() to detect sysctl failures, and skip the testrun when appropriate.

2022-02-20selftests/bpf: Fix btfgen testsAndrii Nakryiko3-7/+14
There turned out to be a few problems with btfgen selftests. First, core_btfgen tests are failing in BPF CI due to the use of full-featured bpftool, which has extra dependencies on libbfd, libcap, etc, which are present in BPF CI's build environment, but those shared libraries are missing in QEMU image in which test_progs is running. To fix this problem, use minimal bootstrap version of bpftool instead. It only depend on libelf and libz, same as libbpf, so doesn't add any new requirements (and bootstrap bpftool still implementes entire `bpftool gen` functionality, which is quite convenient). Second problem is even more interesting. Both core_btfgen and core_reloc reuse the same set of struct core_reloc_test_case array of test case definitions. That in itself is not a problem, but btfgen test replaces test_case->btf_src_file property with the path to temporary file into which minimized BTF is output by bpftool. This interferes with original core_reloc tests, depending on order of tests execution (core_btfgen is run first in sequential mode and skrews up subsequent core_reloc run by pointing to already deleted temporary file, instead of the original BTF files) and whether those two runs share the same process (in parallel mode the chances are high for them to run in two separate processes and so not interfere with each other). To prevent this interference, create and use local copy of a test definition. Mark original array as constant to catch accidental modifcations. Note that setup_type_id_case_success() and setup_type_id_case_success() still modify common test_case->output memory area, but it is ok as each setup function has to re-initialize it completely anyways. In sequential mode it leads to deterministic and correct initialization. In parallel mode they will either each have their own process, or if core_reloc and core_btfgen happen to be run by the same worker process, they will still do that sequentially within the worker process. If they are sharded across multiple processes, they don't really share anything anyways. Also, rename core_btfgen into core_reloc_btfgen, as it is indeed just a "flavor" of core_reloc test, not an independent set of tests. So make it more obvious. Last problem that needed solving was that location of bpftool differs between test_progs and test_progs' flavors (e.g., test_progs-no_alu32). To keep it simple, create a symlink to bpftool both inside selftests/bpf/ directory and selftests/bpf/<flavor> subdirectory. That way, from inside core_reloc test, location to bpftool is just "./bpftool". v2->v3: - fix bpftool location relative the test_progs-no_alu32; v1->v2: - fix corruption of core_reloc_test_case.

Since commit 2843ff6f36db ("mptcp: remote addresses fullmesh"), an MPTCP client can attempt creating multiple MPJ subflow simultaneusly. In such scenario the server, when syncookies are enabled, could end-up accepting incoming MPJ syn even above the configured subflow limit, as the such limit can be enforced in a reliable way only after the subflow creation. In case of syncookie, only after the 3rd ack reception. As a consequence the related self-tests case sporadically fails, as it verify that the server always accept the expected number of MPJ syn. Address the issues relaxing the MPJ syn number constrain. Note that the check on the accepted number of MPJ 3rd ack still remains intact.

This is due to that fact that all VMSAs need to be added into the VM with LAUNCH_UPDATE_VMSA before lAUNCH_FINISH.

2022-02-17selftests: mptcp: increase timeout to 20 minutesMatthieu Baerts1-1/+1
With the increase number of tests, one CI instance, using a debug kernel config and not recent hardware, takes around 10 minutes to execute the slowest MPTCP test: mptcp_join.sh. Even if most CIs don't take that long to execute these tests -- typically max 10 minutes to run all selftests -- it will help some of them if the timeout is increased. The timeout could be disabled but it is always good to have an extra safeguard, just in case. Please note that on slow public CIs with kernel debug settings, it has been observed it can easily take up to 45 minutes to execute all tests in this very slow environment with other jobs running in parallel. The slowest test, mptcp_join.sh takes ~30 minutes in this case. In such environments, the selftests timeout set in the 'settings' file is disabled because this environment is known as being exceptionnally slow. It has been decided not to take such exceptional environments into account and set the timeout to 20min.

2022-02-17selftests/sgx: Treat CC as one argumentMuhammad Usama Anjum1-1/+1
CC can have multiple sub-strings like "ccache gcc". For check_cc.sh, CC needs to be treated like one argument. Put double quotes around it to make CC one string and hence one argument.

Add check to test if CC has a string. CC can have multiple sub-strings like "ccache gcc". Erorr pops up if it is treated as single string and double quotes are used around it.

2022-02-16selftests/bpf: Test "bpftool gen min_core_btf"Mauricio Vásquez1-2/+48
This commit reuses the core_reloc test to check if the BTF files generated with "bpftool gen min_core_btf" are correct. This introduces test_core_btfgen() that runs all the core_reloc tests, but this time the source BTF files are generated by using "bpftool gen min_core_btf". The goal of this test is to check that the generated files are usable, and not to check if the algorithm is creating an optimized BTF file.
