selftests/bpf: Return true/false (not 1/0) from bool functions

2022-07-14T06:09:16Z

Return boolean values ("true" or "false") instead of 1 or 0 from bool functions. This fixes the following warnings from coccicheck: tools/testing/selftests/bpf/progs/test_xdp_noinline.c:407:9-10: WARNING: return of 0/1 in function 'decap_v4' with return type bool tools/testing/selftests/bpf/progs/test_xdp_noinline.c:389:9-10: WARNING: return of 0/1 in function 'decap_v6' with return type bool tools/testing/selftests/bpf/progs/test_xdp_noinline.c:290:9-10: WARNING: return of 0/1 in function 'encap_v6' with return type bool tools/testing/selftests/bpf/progs/test_xdp_noinline.c:264:9-10: WARNING: return of 0/1 in function 'parse_tcp' with return type bool tools/testing/selftests/bpf/progs/test_xdp_noinline.c:242:9-10: WARNING: return of 0/1 in function 'parse_udp' with return type bool Generated by: scripts/coccinelle/misc/boolreturn.cocci Suggested-by: Stanislav Fomichev Signed-off-by: Linkui Xiao Signed-off-by: Andrii Nakryiko Reviewed-by: Stanislav Fomichev Link: https://lore.kernel.org/bpf/20220714015647.25074-1-xiaolinkui@kylinos.cn

selftests/bpf: Normalize XDP section names in selftests

2021-09-28T20:51:19Z

Convert almost all SEC("xdp_blah") uses to strict SEC("xdp") to comply with strict libbpf 1.0 logic of exact section name match for XDP program types. There is only one exception, which is only tested through iproute2 and defines multiple XDP programs within the same BPF object. Given iproute2 still works in non-strict libbpf mode and it doesn't have means to specify XDP programs by its name (not section name/title), leave that single file alone for now until iproute2 gains lookup by function/program name.

selftests/bpf: Modernize xdp_noinline test w/ skeleton and __noinline

2020-09-04T00:14:40Z

Update xdp_noinline to use BPF skeleton and force __noinline on helper sub-programs. Also, split existing logic into v4- and v6-only to complicate sub-program calling patterns (partially overlapped sets of functions for entry-level BPF programs).

selftests: Use consistent include paths for libbpf

2020-01-21T00:37:45Z

Fix all selftests to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To not break the build, keep the old include path until everything has been changed to the new one; a subsequent patch will remove that.

selftests: bpf: Move bpf_printk to bpf_helpers.h

2019-05-24T20:47:17Z

bpf_printk is a macro which is commonly used to print out debug messages in BPF programs and it was copied in many selftests and samples. Since all of them include bpf_helpers.h, this change moves the macro there. Signed-off-by: Michal Rostecki Signed-off-by: Alexei Starovoitov
