[PATCH V2] selftests: Use -isystem instead of -I to include headers

by Muhammad Usama Anjum

Selftests need kernel headers and glibc for compilation. In compilation of selftests, uapi headers from kernel source are used instead of default ones while glibc has already been compiled with different header files installed in the operating system. So there can be redefination warnings from compiler. These warnings can be suppressed by using -isystem to include the uapi headers.

[PATCH V2 0/2] selftests: sgx: Fix build of test_sgx

by Muhammad Usama Anjum

CC can have multiple sub-strings like "ccache gcc". Build system of sgx selftest is unable to support this use case and test_sgx isn't built. Then rsync gives an erorr: rsync: [sender] link_stat "//linux/build/kselftest/sgx/test_sgx" failed: No such file or directory (2) rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1333) [sender=3.2.3] This can be fixed if CC is considered to have one string while passing to check_cc.sh script and inside this script, CC is expanded before execution. Following build tests have been performed to confirm that these patches don't break anything else. The verification has also been done through KernelCI scripts locally as KernelCI has caught this bug: 1) cd tools/testing/selftests && make 2) make -C tools/testing/selftests 3) make -C tools/testing/selftests O=build 4) make -C tools/testing/selftests O=build CC="ccache gcc" 5) ./kci_build make_kselftest Muhammad Usama Anjum (2): selftests: x86: add validity check and allow field splitting selftests: sgx: Treat CC as one argument tools/testing/selftests/sgx/Makefile | 2 +- tools/testing/selftests/x86/check_cc.sh | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) -- 2.30.2

[PATCH v5 1/6] kunit: Introduce _NULL and _NOT_NULL macros

by Ricardo Ribalda

Today, when we want to check if a pointer is NULL and not ERR we have two options: KUNIT_EXPECT_TRUE(test, ptr == NULL); or KUNIT_EXPECT_PTR_NE(test, ptr, (struct mystruct *)NULL); Create a new set of macros that take care of NULL checks.

[PATCH v3] selftests/ftrace: Do not trace do_softirq because of PREEMPT_RT

by Krzysztof Kozlowski

The PREEMPT_RT patchset does not use do_softirq() function thus trying to filter for do_softirq fails for such kernel: echo do_softirq ftracetest: 81: echo: echo: I/O error Choose some other visible function for the test. The function does not have to be actually executed during the test, because it is only testing filter API interface.
