Pu Lehui	994ff2f797	selftests/bpf: Enable inline bpf_kptr_xchg() test for RV64 ... Enable inline bpf_kptr_xchg() test for RV64, and the test have passed as show below: Summary: 1/0 PASSED, 0 SKIPPED, 0 FAILED Signed-off-by: Pu Lehui <pulehui@huawei.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Björn Töpel <bjorn@kernel.org> Link: https://lore.kernel.org/bpf/20240130124659.670321-3-pulehui@huaweicloud.com	2024-02-01 11:35:48 +01:00
Hou Tao	29f868887a	selftests/bpf: Enable kptr_xchg_inline test for arm64 ... Now arm64 bpf jit has enable bpf_jit_supports_ptr_xchg(), so enable the test for arm64 as well.

Hou Tao	17bda53e43	selftests/bpf: Test the inlining of bpf_kptr_xchg() ... The test uses bpf_prog_get_info_by_fd() to obtain the xlated instructions of the program first. Since these instructions have already been rewritten by the verifier, the tests then checks whether the rewritten instructions are as expected. And to ensure LLVM generates code exactly as expected, use inline assembly and a naked function.
