2022-02-26selftests/memfd: clean up mapping in mfd_fail_writeMike Kravetz1-0/+1
Running the memfd script ./run_hugetlbfs_test.sh will often end in error as follows: memfd-hugetlb: CREATE memfd-hugetlb: BASIC memfd-hugetlb: SEAL-WRITE memfd-hugetlb: SEAL-FUTURE-WRITE memfd-hugetlb: SEAL-SHRINK fallocate(ALLOC) failed: No space left on device ./run_hugetlbfs_test.sh: line 60: 166855 Aborted (core dumped) ./memfd_test hugetlbfs opening: ./mnt/memfd fuse: DONE If no hugetlb pages have been preallocated, run_hugetlbfs_test.sh will allocate 'just enough' pages to run the test. In the SEAL-FUTURE-WRITE test the mfd_fail_write routine maps the file, but does not unmap. As a result, two hugetlb pages remain reserved for the mapping. When the fallocate call in the SEAL-SHRINK test attempts allocate all hugetlb pages, it is short by the two reserved pages. Fix by making sure to unmap in mfd_fail_write.

2022-02-19selftests: mptcp: be more conservative with cookie MPJ limitsPaolo Abeni1-3/+12
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.

Because old kernel headers don't have definition of macro __NR_clone3 which is required for these two tests. Since under selftests/, we can install headers once for all tests (the default INSTALL_HDR_PATH is usr/include), fix it by adding usr/include to the list of directories to be searched.

2022-02-04selftests: fixup build warnings in pidfd / clone3 testsAxel Rasmussen3-8/+5
These are some trivial fixups, which were needed to build the tests with clang and -Werror. The following issues are fixed: - Remove various unused variables. - In child_poll_leader_exit_test, clang isn't smart enough to realize syscall(SYS_exit, 0) won't return, so it complains we never return from a non-void function. Add an extra exit(0) to appease it. - In test_pidfd_poll_leader_exit, ret may be branched on despite being uninitialized, if we have !use_waitpid. Initialize it to zero to get the right behavior in that case.

2022-02-04pidfd: fix test failure due to stack overflow on some archesAxel Rasmussen2-7/+28
When running the pidfd_fdinfo_test on arm64, it fails for me. After some digging, the reason is that the child exits due to SIGBUS, because it overflows the 1024 byte stack we've reserved for it. To fix the issue, increase the stack size to 8192 bytes (this number is somewhat arbitrary, and was arrived at through experimentation -- I kept doubling until the failure no longer occurred). Also, let's make the issue easier to debug. wait_for_pid() returns an ambiguous value: it may return -1 in all of these cases: 1. waitpid() itself returned -1 2. waitpid() returned success, but we found !WIFEXITED(status). 3. The child process exited, but it did so with a -1 exit code. There's no way for the caller to tell the difference. So, at least log which occurred, so the test runner can debug things. While debugging this, I found that we had !WIFEXITED(), because the child exited due to a signal. This seems like a reasonably common case, so also print out whether or not we have WIFSIGNALED(), and the associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing clearly when it occurs. Finally, I'm suspicious of allocating the child's stack on our stack. man clone(2) suggests that the correct way to do this is with mmap(), and in particular by setting MAP_STACK. So, switch to doing it that way instead.

All the tests return values are then added in a single variable which is checked to verify failures. This approach can have side effects which result in reporting the wrong kselftest exit status.

2022-01-28kselftest/arm64: Correct logging of FPSIMD register read via ptraceMark Brown1-1/+1
There's a cut'n'paste error in the logging for our test for reading register state back via ptrace, correctly say that we did a read instead of a write.

2022-01-28kselftest/arm64: Skip VL_INHERIT tests for unsupported vector typesMark Brown1-1/+8
Currently we unconditionally test the ability to set the vector length inheritance flag via ptrace meaning that we generate false failures on systems that don't support SVE when we attempt to set the vector length there. Check the hwcap and mark the tests as skipped when it's not present.

Report mincore.check_file_mmap as SKIP instead of FAIL if the underlying filesystem lacks support of O_TMPFILE or fallocate since such failures are not really related to mincore functionality.
