Hi, The simple patchset tries to enable kfunc call for arm64. Patch #1 just overrides bpf_jit_supports_kfunc_call() to enable kfunc call, patch #2 unexports the subtests in ksyms_module.c to fix the confusion in test output and patch #3 add a test in ksyms_module.c to ensure s32 is sufficient for kfunc offset. Change Log: v3: * 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@huawei.com/ * add a test to check whether imm will be overflowed for kfunc call v1: https://lore.kernel.org/bpf/20220119144942.305568-1-houtao1@huawei.com Hou Tao (3): bpf, arm64: enable kfunc call selftests/bpf: do not export subtest as standalone test selftests/bpf: check whether s32 is sufficient for kfunc offset arch/arm64/net/bpf_jit_comp.c | 5 ++ .../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 +- 6 files changed, 54 insertions(+), 13 deletions(-)
