[PATCH net-next 0/1] selftests: drv-net-hw: fix pp_alloc_fail test error

by John Daley

The tool pp_alloc_fail.py tested error recovery by injecting errors into page_pool_alloc_pages(). Perhaps due to the netmems conversion, page_pool_put_full_page() does not end up calling that function. page_pool_alloc_netmems() seems to be the base function for all the the allocation functions in the API call, so put the error injection there instead.

[PATCH v3 2/2] selftests/lib.mk: Introduce check to validate required dependencies

by Siddharth Menon

Currently, kselftests does not have a generalised mechanism to skip compilation and run tests when required kernel configuration flags are missing. This patch introduces a check to validate the presence of required config flags specified in the selftest config files. In case scripts/config or the current kernel config is not found, this check is skipped. In order to skip checking for config options required to compile the test, set the environment variable SKIP_CHECKS=1. example usage: ``` make SKIP_CHECKS=1 -C livepatch/ ``` Suggested-by: Petr Mladek <pmladek(a)suse.com> Suggested-by: Miroslav Benes <mbenes(a)suse.cz> Signed-off-by: Siddharth Menon <simeddon(a)gmail.com> --- v1->v2: - Moved the logic to check for required configurations to an external script v2 -> v3: - Add SKIP_CHECKS flag to skip checking the dependencies if required - Updated the test skip statement to be more meaningful tools/testing/selftests/lib.mk | 15 +++++++++++++-- 1 file changed, 13 insertions(+), 2 deletions(-) mode change 100644 => 100755 tools/testing/selftests/lib.mk diff --git a/tools/testing/selftests/lib.mk b/tools/testing/selftests/lib.mk old mode 100644 new mode 100755 index d6edcfcb5be8..0e11d1d3bab8 --- a/tools/testing/selftests/lib.mk +++ b/tools/testing/selftests/lib.mk @@ -97,7 +97,18 @@ TEST_GEN_PROGS := $(patsubst %,$(OUTPUT)/%,$(TEST_GEN_PROGS)) TEST_GEN_PROGS_EXTENDED := $(patsubst %,$(OUTPUT)/%,$(TEST_GEN_PROGS_EXTENDED)) TEST_GEN_FILES := $(patsubst %,$(OUTPUT)/%,$(TEST_GEN_FILES)) -all: $(TEST_GEN_PROGS) $(TEST_GEN_PROGS_EXTENDED) $(TEST_GEN_FILES) \ +TEST_DIR := $(shell pwd) + +check_kselftest_deps: +ifneq ($(SKIP_CHECKS),1) + @$(selfdir)/check_kselftest_deps.pl $(TEST_DIR) $(CC) || { \ + echo "Skipping test: $(notdir $(TEST_DIR)) (missing required kernel features)"; \ + exit 1; \ + } +endif + + +all: check_kselftest_deps $(TEST_GEN_PROGS) $(TEST_GEN_PROGS_EXTENDED) $(TEST_GEN_FILES) \ $(if $(TEST_GEN_MODS_DIR),gen_mods_dir) define RUN_TESTS @@ -228,4 +239,4 @@ $(OUTPUT)/%:%.S $(LINK.S) $^ $(LDLIBS) -o $@ endif -.PHONY: run_tests all clean install emit_tests gen_mods_dir clean_mods_dir +.PHONY: run_tests all clean install emit_tests gen_mods_dir clean_mods_dir check_kselftest_deps -- 2.39.5

[PATCH v3 1/2] selftests: Introduce script to validate required dependencies

by Siddharth Menon

This patch adds a script to validate that the current kernel configuration satisfies the requirements for selftests by comparing the current kernel configs against the required selftest configs. The script also runs kselftest_deps.sh to check for any missing libraries required by the selftest. A config mismatch exits with error value 1 while matching configs or missing config files exit with value 0. In order to silence missing dependency output, set the environment variable SILENCE=1. The code for extracting the current kernel configs is adapted from scripts/kconfig/streamline_config.pl.

[PATCH v5 0/4] Migrate PCI Endpoint Subsystem tests to Kselftest

by Manivannan Sadhasivam

Hi, This series carries forward the effort to add Kselftest for PCI Endpoint Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version based on another patch that fixes the return values of IOCTLs in pci_endpoint_test driver and did many cleanups. Since the resulting work modified the initial version substantially, I took over the authorship. This series also incorporates the review comment by Shuah Khan [2] to move the existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before migrating to Kselftest framework. I made sure that the tests are executable in each commit and updated documentation accordingly. - Mani [1] https://lore.kernel.org/linux-pci/20221007053934.5188-1-aman1.gupta@samsung… [2] https://lore.kernel.org/linux-pci/b2a5db97-dc59-33ab-71cd-f591e0b1b34d@linu… Changes in v5: * Incorporated comments from Niklas * Added a patch to fix the DMA MEMCPY check in pci-epf-test driver * Collected tags * Rebased on top of pci/next 0333f56dbbf7ef6bb46d2906766c3e1b2a04a94d Changes in v4: * Dropped the BAR fix patches and submitted them separately: https://lore.kernel.org/linux-pci/20241231130224.38206-1-manivannan.sadhasi… * Rebased on top of pci/next 9e1b45d7a5bc0ad20f6b5267992da422884b916e Changes in v3: * Collected tags. * Added a note about failing testcase 10 and command to skip it in documentation. * Removed Aman Gupta and Padmanabhan Rajanbabu from CC as their addresses are bouncing.

[PATCH 1/2] selftests/mm: use selftests framework to print test result.
