kseltest/cgroup: Make test_stress.sh work if run interactively

2022-06-09T08:26:31+00:00

commit 213adc63dfbcdff9a0c19ec1f2681fda9c05cf6d upstream.

Commit 54de76c01239 ("kselftest/cgroup: fix test_stress.sh to use OUTPUT
dir") changes the test_core command path from . to $OUTPUT. However,
variable OUTPUT may not be defined if the command is run interactively.
Fix that by using ${OUTPUT:-.} to cover both cases.

kselftest/cgroup: fix test_stress.sh to use OUTPUT dir

2022-06-09T08:25:50+00:00

[ Upstream commit 54de76c0123915e7533ce352de30a1f2d80fe81f ]

Running cgroup kselftest with O= fails to run the with_stress test due
to hardcoded ./test_core. Find test_core binary using the OUTPUT directory.

selftests: cgroup: Test open-time cgroup namespace usage for migration checks

2022-01-06T21:02:29+00:00

When a task is writing to an fd opened by a different task, the perm check
should use the cgroup namespace of the latter task. Add a test for it.

selftests: cgroup: Make cg_create() use 0755 for permission instead of 0644

2022-01-06T21:02:29+00:00

0644 is an odd perm to create a cgroup which is a directory. Use the regular
0755 instead. This is necessary for euid switching test case.

selftests/cgroup: remove ARRAY_SIZE define from cgroup_util.h

2021-12-11T00:50:31+00:00

ARRAY_SIZE is defined in several selftests. Remove definitions from
individual test files and include header file for the define instead.
ARRAY_SIZE define is added in a separate patch to prepare for this
change.

Remove ARRAY_SIZE from cgroup_util.h and pickup the one defined in
kselftest.h.

selftests: cgroup: build error multiple outpt files

2021-12-10T23:46:01+00:00

When building selftests/cgroup: with clang the following error are seen:

clang -Wall -pthread    test_memcontrol.c cgroup_util.c ../clone3/clone3_selftests.h  -o .../builds/current/kselftest/cgroup/test_memcontrol
clang: error: cannot specify -o when generating multiple output files
make[3]: *** [../lib.mk:146: .../builds/current/kselftest/cgroup/test_memcontrol] Error 1

Rework to add the header files to LOCAL_HDRS before including ../lib.mk,
since the dependency is evaluated in '$(OUTPUT)/%:%.c $(LOCAL_HDRS)' in
file lib.mk.
