selftests/bpf: install files test_xdp_vlan.sh

2019-08-21T15:06:04+00:00

When ./test_xdp_vlan_mode_generic.sh runs it complains that it can't find file test_xdp_vlan.sh. # selftests: bpf: test_xdp_vlan_mode_generic.sh # ./test_xdp_vlan_mode_generic.sh: line 9: ./test_xdp_vlan.sh: No such file or directory Rework so that test_xdp_vlan.sh gets installed, added to the variable TEST_PROGS_EXTENDED.

selftests/bpf: fix test_btf_dump with O=

2019-08-21T15:00:59+00:00

test_btf_dump fails when run with O=, because it needs to access source files and assumes they live in ./progs/, which is not the case in this scenario. Fix by instructing kselftest to copy btf_dump_test_case_*.c files to the test directory. Since kselftest does not preserve directory structure, adjust the test to look in ./progs/ and then in ./.

selftests/bpf: add wrapper scripts for test_xdp_vlan.sh

2019-08-05T18:17:40+00:00

In-order to test both native-XDP (xdpdrv) and generic-XDP (xdpgeneric) create two wrapper test scripts, that start the test_xdp_vlan.sh script with these modes. Signed-off-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

selftests/bpf: structure test_{progs, maps, verifier} test runners uniformly

2019-07-17T01:33:12+00:00

It's easier to follow the logic if it's structured the same. There is just slight difference between test_progs/test_maps and test_verifier. test_verifier's verifier/*.c files are not really compilable C files (they are more of include headers), so they can't be specified as explicit dependencies of test_verifier.

selftests/bpf: fix test_verifier/test_maps make dependencies

2019-07-17T01:33:12+00:00

e46fc22e60a4 ("selftests/bpf: make directory prerequisites order-only") exposed existing problem in Makefile for test_verifier and test_maps tests: their dependency on auto-generated header file with a list of all tests wasn't recorded explicitly. This patch fixes these issues.

selftests/bpf: put test_stub.o into $(OUTPUT)

2019-07-15T21:10:46+00:00

Add a rule to put test_stub.o in $(OUTPUT) and change the references to it accordingly. This prevents test_stub.o from being created in the source directory. Signed-off-by: Ilya Leoshkevich Acked-by: Andrii Nakryiko Signed-off-by: Daniel Borkmann

selftests/bpf: make directory prerequisites order-only

2019-07-15T21:10:17+00:00

When directories are used as prerequisites in Makefiles, they can cause a lot of unnecessary rebuilds, because a directory is considered changed whenever a file in this directory is added, removed or modified. If the only thing a target is interested in is the existence of the directory it depends on, which is the case for selftests/bpf, this directory should be specified as an order-only prerequisite: it would still be created in case it does not exist, but it would not trigger a rebuild of a target in case it's considered changed.

selftests/bpf: compile progs with -D__TARGET_ARCH_$(SRCARCH)

selftests/bpf: do not ignore clang failures

2019-07-12T13:18:33+00:00

When compiling an eBPF prog fails, make still returns 0, because failing clang command's output is piped to llc and therefore its exit status is ignored. When clang fails, pipe the string "clang failed" to llc. This will make llc fail with an informative error message. This solution was chosen over using pipefail, having separate targets or getting rid of llc invocation due to its simplicity. In addition, pull Kbuild.include in order to get .DELETE_ON_ERROR target, which would cause partial .o files to be removed.
