[PATCH v6 0/8] Add printf attribute to kselftest functions

by Maciej Wieczor-Retman

kselftest.h declares many variadic functions that can print some formatted message while also executing selftest logic. These declarations don't have any compiler mechanism to verify if passed arguments are valid in comparison with format specifiers used in printf() calls. Attribute addition can make debugging easier, the code more consistent and prevent mismatched or missing variables. The first patch adds __printf() macro and applies it to all functions in kselftest.h that use printf format specifiers. After compiling all selftests using: make -C tools/testing/selftests many instances of format specifier mismatching are exposed in the form of -Wformat warnings. Fix the mismatched format specifiers caught by __printf() attribute in multiple tests. Series is based on kselftests next branch. Changelog v6: - Add methodology notes to all patches. - No functional changes in the patches. Changelog v5: - Mention in the cover letter what methodology was used to find the mismatched format specifiers. - No functional changes in the patches. Changelog v4: - Fix patch 1/8 subject typo. - Add Reinette's reviewed-by tags. - Rebase onto new kselftest/next patches. Changelog v3: - Changed git signature from Wieczor-Retman Maciej to Maciej Wieczor-Retman. - Added one review tag. - Rebased onto updated kselftests next branch. Changelog v2: - Add review and fixes tags to patches. - Add two patches with mismatch fixes. - Fix missed attribute in selftests/kvm.

[PATCH net v2 0/4] selftests: openvswitch: Minor fixes for some systems

by Aaron Conole

A number of corner cases were caught when trying to run the selftests on older systems. Missed skip conditions, some error cases, and outdated python setups would all report failures but the issue would actually be related to some other condition rather than the selftest suite. Address these individual cases. Aaron Conole (4): selftests: openvswitch: Add version check for pyroute2 selftests: openvswitch: Catch cases where the tests are killed selftests: openvswitch: Skip drop testing on older kernels selftests: openvswitch: Fix the ct_tuple for v4 .../selftests/net/openvswitch/openvswitch.sh | 21 +++++++- .../selftests/net/openvswitch/ovs-dpctl.py | 48 ++++++++++++++++++- 2 files changed, 66 insertions(+), 3 deletions(-) -- 2.41.0

[PATCH] selftests/powerpc: Fix emit_tests to work with run_kselftest.sh

by Michael Ellerman

In order to use run_kselftest.sh the list of tests must be emitted to populate kselftest-list.txt. The powerpc Makefile is written to use EMIT_TESTS. But support for EMIT_TESTS was dropped in commit d4e59a536f50 ("selftests: Use runner.sh for emit targets"). Although prior to that commit a548de0fe8e1 ("selftests: lib.mk: add test execute bit check to EMIT_TESTS") had already broken run_kselftest.sh for powerpc due to the executable check using the wrong path. It can be fixed by replacing the EMIT_TESTS definitions with actual emit_tests rules in the powerpc Makefiles. This makes run_kselftest.sh able to run powerpc tests: $ cd linux $ export ARCH=powerpc $ export CROSS_COMPILE=powerpc64le-linux-gnu- $ make headers $ make -j -C tools/testing/selftests install $ grep -c "^powerpc" tools/testing/selftests/kselftest_install/kselftest-list.txt 182 Fixes: d4e59a536f50 ("selftests: Use runner.sh for emit targets") Signed-off-by: Michael Ellerman <mpe(a)ellerman.id.au> --- tools/testing/selftests/powerpc/Makefile | 7 +++---- tools/testing/selftests/powerpc/pmu/Makefile | 11 ++++++----- 2 files changed, 9 insertions(+), 9 deletions(-) I'll plan to merge this via the powerpc tree. cheers diff --git a/tools/testing/selftests/powerpc/Makefile b/tools/testing/selftests/powerpc/Makefile index 49f2ad1793fd..7ea42fa02eab 100644 --- a/tools/testing/selftests/powerpc/Makefile +++ b/tools/testing/selftests/powerpc/Makefile @@ -59,12 +59,11 @@ override define INSTALL_RULE done; endef -override define EMIT_TESTS +emit_tests: +@for TARGET in $(SUB_DIRS); do \ BUILD_TARGET=$(OUTPUT)/$$TARGET; \ - $(MAKE) OUTPUT=$$BUILD_TARGET -s -C $$TARGET emit_tests;\ + $(MAKE) OUTPUT=$$BUILD_TARGET -s -C $$TARGET $@;\ done; -endef override define CLEAN +@for TARGET in $(SUB_DIRS); do \ @@ -77,4 +76,4 @@ endef tags: find . -name '*.c' -o -name '*.h' | xargs ctags -.PHONY: tags $(SUB_DIRS) +.PHONY: tags $(SUB_DIRS) emit_tests diff --git a/tools/testing/selftests/powerpc/pmu/Makefile b/tools/testing/selftests/powerpc/pmu/Makefile index 2b95e44d20ff..a284fa874a9f 100644 --- a/tools/testing/selftests/powerpc/pmu/Makefile +++ b/tools/testing/selftests/powerpc/pmu/Makefile @@ -30,13 +30,14 @@ override define RUN_TESTS +TARGET=event_code_tests; BUILD_TARGET=$$OUTPUT/$$TARGET; $(MAKE) OUTPUT=$$BUILD_TARGET -C $$TARGET run_tests endef -DEFAULT_EMIT_TESTS := $(EMIT_TESTS) -override define EMIT_TESTS - $(DEFAULT_EMIT_TESTS) +emit_tests: + for TEST in $(TEST_GEN_PROGS); do \ + BASENAME_TEST=`basename $$TEST`; \ + echo "$(COLLECTION):$$BASENAME_TEST"; \ + done +TARGET=ebb; BUILD_TARGET=$$OUTPUT/$$TARGET; $(MAKE) OUTPUT=$$BUILD_TARGET -s -C $$TARGET emit_tests +TARGET=sampling_tests; BUILD_TARGET=$$OUTPUT/$$TARGET; $(MAKE) OUTPUT=$$BUILD_TARGET -s -C $$TARGET emit_tests +TARGET=event_code_tests; BUILD_TARGET=$$OUTPUT/$$TARGET; $(MAKE) OUTPUT=$$BUILD_TARGET -s -C $$TARGET emit_tests -endef DEFAULT_INSTALL_RULE := $(INSTALL_RULE) override define INSTALL_RULE @@ -64,4 +65,4 @@ sampling_tests: event_code_tests: TARGET=$@; BUILD_TARGET=$$OUTPUT/$$TARGET; mkdir -p $$BUILD_TARGET; $(MAKE) OUTPUT=$$BUILD_TARGET -k -C $$TARGET all -.PHONY: all run_tests ebb sampling_tests event_code_tests +.PHONY: all run_tests ebb sampling_tests event_code_tests emit_tests -- 2.41.0

[PATCH v5 0/8] Add printf attribute to kselftest functions

by Maciej Wieczor-Retman

kselftest.h declares many variadic functions that can print some formatted message while also executing selftest logic. These declarations don't have any compiler mechanism to verify if passed arguments are valid in comparison with format specifiers used in printf() calls. Attribute addition can make debugging easier, the code more consistent and prevent mismatched or missing variables. The first patch adds __printf() macro and applies it to all functions in kselftest.h that use printf format specifiers. After compiling all selftests using: make -C tools/testing/selftests many instances of format specifier mismatching are exposed in the form of -Wformat warnings. Fix the mismatched format specifiers caught by __printf() attribute in multiple tests. Series is based on kselftests next branch. Changelog v5: - Mention in the cover letter what methodology was used to find the mismatched format specifiers. - No functional changes in the patches. Changelog v4: - Fix patch 1/8 subject typo. - Add Reinette's reviewed-by tags. - Rebase onto new kselftest/next patches. Changelog v3: - Changed git signature from Wieczor-Retman Maciej to Maciej Wieczor-Retman. - Added one review tag. - Rebased onto updated kselftests next branch. Changelog v2: - Add review and fixes tags to patches. - Add two patches with mismatch fixes. - Fix missed attribute in selftests/kvm.
