* selftests/timens: handle a case when alarm clocks are not supportedAndrei Vagin2020-05-225-3/+24
| | | | | | | | | | | This can happen if a testing node doesn't have RTC (real time clock) hardware or it doesn't support alarms.

One fixes up the SPDX tag for a single driver, while the other two go through the tree and add SPDX tags for all of the .gitignore files as needed. Nothing too complex, but you will get a merge conflict with your current tree, that should be trivial to handle (one file modified by two things, one file deleted.) All three of these have been in linux-next for a while, with no reported issues other than the merge conflict" * tag 'spdx-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: ASoC: MT6660: make spdxcheck.py happy .gitignore: add SPDX License Identifier .gitignore: remove too obvious comments

* | selftests: use LDLIBS for libraries instead of LDFLAGSDmitry Safonov2020-02-131-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While building selftests, the following errors were observed: > tools/testing/selftests/timens' > gcc -Wall -Werror -pthread -lrt -ldl timens.c -o tools/testing/selftests/timens/timens > /usr/bin/ld: /tmp/ccGy5CST.o: in function `check_config_posix_timers': > timens.c:(.text+0x65a): undefined reference to `timer_create' > collect2: error: ld returned 1 exit status Quoting commit 870f193d48c2 ("selftests: net: use LDLIBS instead of LDFLAGS"): The default Makefile rule looks like: $(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS) When linking is done by gcc itself, no issue, but when it needs to be passed to proper ld, only LDLIBS follows and then ld cannot know what libs to link with. More detail: https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html LDFLAGS Extra flags to give to compilers when they are supposed to invoke the linker, ‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable instead. LDLIBS Library flags or names given to compilers when they are supposed to invoke the linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS variable. While at here, correct other selftests, not only timens ones.

* selftests/timens: Add Time Namespace test for supported clocksDmitry Safonov2020-01-146-0/+324
A test to check that all supported clocks work on host and inside a new time namespace. Use both ways to get time: through VDSO and by entering the kernel with implicit syscall. Introduce a new timens directory in selftests framework for the next timens tests. Output on success: 1..10 ok 1 Passed for CLOCK_BOOTTIME (syscall) ok 2 Passed for CLOCK_BOOTTIME (vdso) ok 3 Passed for CLOCK_BOOTTIME_ALARM (syscall) ok 4 Passed for CLOCK_BOOTTIME_ALARM (vdso) ok 5 Passed for CLOCK_MONOTONIC (syscall) ok 6 Passed for CLOCK_MONOTONIC (vdso) ok 7 Passed for CLOCK_MONOTONIC_COARSE (syscall) ok 8 Passed for CLOCK_MONOTONIC_COARSE (vdso) ok 9 Passed for CLOCK_MONOTONIC_RAW (syscall) ok 10 Passed for CLOCK_MONOTONIC_RAW (vdso) # Pass 10 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0 Output with lack of permissions: 1..10 not ok 1 # SKIP need to run as root Output without support of time namespaces: 1..10 not ok 1 # SKIP Time namespaces are not supported Co-developed-by: Andrei Vagin <avagin@openvz.org> Signed-off-by: Andrei Vagin <avagin@gmail.com> Signed-off-by: Dmitry Safonov <dima@arista.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/20191112012724.250792-29-dima@arista.com
