selftest/bpf: Get rid of a bunch of explicit BPF program type setting

2019-10-21T12:49:12+00:00

Now that libbpf can correctly guess BPF program types from section
names, remove a bunch of explicit bpf_program__set_type() calls
throughout tests.

selftests/bpf: Switch test_maps to test_progs' test.h format

2019-10-17T19:15:08+00:00

Make test_maps use tests.h header format consistent with the one used by
test_progs, to facilitate unification.

selftests/bpf: fix test_reuseport_array on s390

2019-07-08T23:10:23+00:00

Fix endianness issue: passing a pointer to 64-bit fd as a 32-bit key
does not work on big-endian architectures. So cast fd to 32-bits when
necessary.

bpf: Add BPF_MAP_TYPE_SK_STORAGE test to test_maps

2019-04-27T16:07:05+00:00

This patch adds BPF_MAP_TYPE_SK_STORAGE test to test_maps.
The src file is rather long, so it is put into another dir map_tests/
and compile like the current prog_tests/ does.  Other existing
tests in test_maps can also be re-factored into map_tests/ in the
future.

bpf: test_maps: fix possible out of bound access warning

2019-02-06T14:48:43+00:00

When compiling test_maps selftest with GCC-8, it warns that an array
might be indexed with a negative value, which could cause a negative
out of bound access, depending on parameters of the function. This
is the GCC-8 warning:

	gcc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../lib/bpf -I../../../../include/generated -DHAVE_GENHDR -I../../../include    test_maps.c /home/breno/Devel/linux/tools/testing/selftests/bpf/libbpf.a -lcap -lelf -lrt -lpthread -o /home/breno/Devel/linux/tools/testing/selftests/bpf/test_maps
	In file included from test_maps.c:16:
	test_maps.c: In function ‘run_all_tests’:
	test_maps.c:1079:10: warning: array subscript -1 is below array bounds of ‘pid_t[ + 1]’ [-Warray-bounds]
	   assert(waitpid(pid[i], &status, 0) == pid[i]);
		  ^~~~~~~~~~~~~~~~~~~~~~~~~~~
	test_maps.c:1059:6: warning: array subscript -1 is below array bounds of ‘pid_t[ + 1]’ [-Warray-bounds]
	   pid[i] = fork();
	   ~~~^~~

This patch simply guarantees that the task(s) variables are unsigned,
thus, they could never be a negative number (which they are not in
current code anyway), hence avoiding an out of bound access warning.

selftests/bpf: skip sockmap in test_maps if kernel doesn't have support

2019-01-31T09:13:21+00:00

Use recently introduced bpf_probe_map_type() to skip test_sockmap()
if map creation fails. The skipped test is indicated in the output.

Example:

test_sockmap SKIP (unsupported map type BPF_MAP_TYPE_SOCKMAP)
Fork 1024 tasks to 'test_update_delete'
...
test_sockmap SKIP (unsupported map type BPF_MAP_TYPE_SOCKMAP)
Fork 1024 tasks to 'test_update_delete'
...
test_maps: OK, 2 SKIPPED
