| Series | selftests/bpf: Improve libc portability / musl support (part 2) | expand |
Hello all, This is part 2 of a series of fixes for libc-related issues encountered building for musl-based systems. The series has been tested with the kernel-patches/bpf CI and locally using mips64el-gcc/musl-libc and QEMU with an OpenWrt rootfs. The patches cover a few areas of portability issues: - problematic libc usage (strtok_r(), stdio macros/reserved identifiers) - gcc compile errors (include header ordering, sequence-point errors) - POSIX vs GNU basename() - missing GNU extensions (<execinfo.h>, C++ <stdbool.h>) - Y2038 and setsockopt() / SO_TIMESTAMPNS_NEW Feedback and suggestions are appreciated! Thanks, Tony Changelog: ---------- v1->v2: (feedback from Andrii) - P2: rewrite simpler code using counter - P5: update description/fix after more research - P6: use weak functions for backtrace stubs - P7: use stdxxx_saved names, update desc Tony Ambardar (8): selftests/bpf: Use portable POSIX basename() selftests/bpf: Fix arg parsing in veristat, test_progs selftests/bpf: Fix error compiling test_lru_map.c selftests/bpf: Fix C++ compile error from missing _Bool type selftests/bpf: Fix redefinition errors compiling lwt_reroute.c selftests/bpf: Fix compile if backtrace support missing in libc selftests/bpf: Fix using stdout, stderr as struct field names selftests/bpf: Fix error compiling tc_redirect.c with musl libc .../selftests/bpf/prog_tests/lwt_reroute.c | 1 + .../selftests/bpf/prog_tests/reg_bounds.c | 2 +- .../selftests/bpf/prog_tests/tc_redirect.c | 12 +-- tools/testing/selftests/bpf/test_cpp.cpp | 4 + tools/testing/selftests/bpf/test_lru_map.c | 3 +- tools/testing/selftests/bpf/test_progs.c | 82 +++++++++++-------- tools/testing/selftests/bpf/test_progs.h | 8 +- tools/testing/selftests/bpf/testing_helpers.c | 4 +- tools/testing/selftests/bpf/veristat.c | 16 ++-- tools/testing/selftests/bpf/xskxceiver.c | 1 + 10 files changed, 78 insertions(+), 55 deletions(-)
