2021-11-07selftests/bpf: Use explicit bpf_prog_test_load() calls everywhereAndrii Nakryiko1-1/+1
-Dbpf_prog_load_deprecated=bpf_prog_test_load trick is both ugly and breaks when deprecation goes into effect due to macro magic. Convert all the uses to explicit bpf_prog_test_load() calls which avoid deprecation errors and makes everything less magical.

2021-10-21selftests/bpf: Switch to ".bss"/".rodata"/".data" lookups for internal mapsAndrii Nakryiko1-2/+9
Utilize libbpf's feature of allowing to lookup internal maps by their ELF section names. No need to guess or calculate the exact truncated prefix taken from the object name.

2020-08-13selftest/bpf: Fix compilation warnings in 32-bit modeAndrii Nakryiko1-3/+3
Fix compilation warnings emitted when compiling selftests for 32-bit platform (x86 in my case). Signed-off-by: Andrii Nakryiko <andriin@fb.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Link: https://lore.kernel.org/bpf/20200813204945.1020225-3-andriin@fb.com
2020-05-09selftests/bpf: Move existing common networking parts into network_helpersStanislav Fomichev1-0/+1
1. Move pkt_v4 and pkt_v6 into network_helpers and adjust the users. 2. Copy-paste spin_lock_thread into two tests that use it.

2019-08-28selftests/bpf: test_progs: remove global fail/success countsStanislav Fomichev1-15/+5
Now that we have a global per-test/per-environment state, there is no longer need to have global fail/success counters (and there is no need to save/get the diff before/after the test). Introduce CHECK_FAIL macro (suggested by Andrii) and covert existing tests to it. CHECK_FAIL uses new test__fail() to record the failure.

2019-04-09bpf, selftest: test global data/bss/rodata sectionsJoe Stringer1-0/+157
Add tests for libbpf relocation of static variable references into the .data, .rodata and .bss sections of the ELF, also add read-only test for .rodata.
