[PATCH bpf-next v1] selftests/bpf: avoid generating untracked files when running bpf selftests

by Jiayuan Chen

Currently, when we run the BPF selftests with the following command: 'make -C tools/testing/selftests TARGETS=bpf SKIP_TARGETS=""' The command generates untracked files and directories: ''' Untracked files: (use "git add <file>..." to include in what will be committed) tools/testing/selftests/bpfFEATURE-DUMP.selftests tools/testing/selftests/bpffeature/ ''' The core reason is our Makefile(tools/testing/selftests/bpf/Makefile) was written like this: ''' OUTPUT := $(OUTPUT)/ $(eval include ../../../build/Makefile.feature) OUTPUT := $(patsubst %/,%,$(OUTPUT)) ''' This way of assigning values to OUTPUT will never be effective for the variable OUTPUT provided via the command argument and sub makefile called like this(tools/testing/selftests/Makefile): ''' all: ... $(MAKE) OUTPUT=$$BUILD_TARGET -C $$TARGET ''' As stated in the GNU make documentation: ''' An argument that contains '=' specifies the value of a variable: 'v=x' sets the value of the variable v to x. If you specify a value in this way, all ordinary assignments of the same variable in the makefile are ignored; we say they have been overridden by the command line argument. ''' According to GNU make, we use override Directive to fix this issue: ''' If you want to set the variable in the makefile even though it was set with a command argument, you can use an override directive, which is a line that looks like this: override variable := value Link: https://www.gnu.org/software/make/manual/make.html#Override-Directive Fixes: dc3a8804d790 ("selftests/bpf: Adapt OUTPUT appending logic to lower versions of Make") Signed-off-by: Jiayuan Chen <mrpre(a)163.com> --- tools/testing/selftests/bpf/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/tools/testing/selftests/bpf/Makefile b/tools/testing/selftests/bpf/Makefile index 9e870e519c30..eb4d21651aa7 100644 --- a/tools/testing/selftests/bpf/Makefile +++ b/tools/testing/selftests/bpf/Makefile @@ -202,9 +202,9 @@ ifeq ($(shell expr $(MAKE_VERSION) \>= 4.4), 1) $(let OUTPUT,$(OUTPUT)/,\ $(eval include ../../../build/Makefile.feature)) else -OUTPUT := $(OUTPUT)/ +override OUTPUT := $(OUTPUT)/ $(eval include ../../../build/Makefile.feature) -OUTPUT := $(patsubst %/,%,$(OUTPUT)) +override OUTPUT := $(patsubst %/,%,$(OUTPUT)) endif endif base-commit: a7c205120d339b6ad2557fe3f33fdf20394f1a0f -- 2.43.5

[PATCH bpf-next v2 0/2] selftests: bpf: Migrate test_xdp_meta.sh to test_progs

by Bastien Curutchet

Hi all, This patch series continues the work to migrate the script tests into prog_tests. test_xdp_meta.sh uses the BPF programs defined in progs/test_xdp_meta.c to do a simple XDP/TC functional test that checks the metadata allocation performed by the bpf_xdp_adjust_meta() helper. This is already partly covered by two tests under prog_tests/: - xdp_context_test_run.c uses bpf_prog_test_run_opts() to verify the validity of the xdp_md context after a call to bpf_xdp_adjust_meta() - xdp_metadata.c ensures that these meta-data can be exchanged through an AF_XDP socket. However test_xdp_meta.sh also verifies that the meta-data initialized in the struct xdp_md is forwarded to the struct __sk_buff used by BPF programs at 'TC level'. To cover this, I add a test case in xdp_context_test_run.c that uses the same BPF programs from progs/test_xdp_meta.c. --- Changes in v2: - Add missing close_netns() - Use a unique 'close' label - Link to v1: https://lore.kernel.org/r/20241206-xdp_meta-v1-0-5c150618f6e9@bootlin.com --- Bastien Curutchet (2): selftests/bpf: test_xdp_meta: Rename BPF sections selftests/bpf: Migrate test_xdp_meta.sh into xdp_context_test_run.c tools/testing/selftests/bpf/Makefile | 1 - .../bpf/prog_tests/xdp_context_test_run.c | 87 ++++++++++++++++++++++ tools/testing/selftests/bpf/progs/test_xdp_meta.c | 4 +- tools/testing/selftests/bpf/test_xdp_meta.sh | 58 --------------- 4 files changed, 89 insertions(+), 61 deletions(-) --- base-commit: 0c30734c4f35c4784d3d3ca1bb89d9779045878c change-id: 20241203-xdp_meta-868307cd0e03 Best regards, -- Bastien Curutchet (eBPF Foundation) <bastien.curutchet(a)bootlin.com>
