Hi, The patchset add a test for kfunc call to ensure s32 is sufficient for kfunc offset. Patch #1 unexports the subtests in ksyms_module.c to fix the confusion in test output and patch #2 adds a test in ksyms_module.c to ensure s32 is sufficient for kfunc offset. Change Log: v4: * remove merged patch "bpf, arm64: enable kfunc call" * rebased on bpf-next v3: https://lore.kernel.org/bpf/20220130092917.14544-1-hotforest@xxxxxxxxx * patch #2: newly-addded to unexport unnecessary subtests * patch #3: use kallsyms_find() instead of reimplementing it. * patch #3: ensure kfunc call is supported before checking whether s32 will be overflowed or not. v2: https://lore.kernel.org/bpf/20220127071532.384888-1-houtao1@xxxxxxxxxx * add a test to check whether imm will be overflowed for kfunc call v1: https://lore.kernel.org/bpf/20220119144942.305568-1-houtao1@xxxxxxxxxx Hou Tao (2): selftests/bpf: do not export subtest as standalone test selftests/bpf: check whether s32 is sufficient for kfunc offset .../selftests/bpf/prog_tests/ksyms_module.c | 46 ++++++++++++++++++- .../bpf/prog_tests/xdp_adjust_frags.c | 6 --- .../bpf/prog_tests/xdp_adjust_tail.c | 4 +- .../bpf/prog_tests/xdp_cpumap_attach.c | 4 +- .../bpf/prog_tests/xdp_devmap_attach.c | 2 +- 5 files changed, 49 insertions(+), 13 deletions(-) -- 2.35.1
