selftests/bpf: use BPF_KSYSCALL and SEC("ksyscall") in selftests

2022-07-19T16:33:18Z

Convert few selftest that used plain SEC("kprobe") with arch-specific syscall wrapper prefix to ksyscall/kretsyscall and corresponding BPF_KSYSCALL macro. test_probe_user.c is especially benefiting from this simplification.

selftests/bpf: Fix an endianness issue in bpf_syscall_macro test

2022-02-09T05:16:14Z

bpf_syscall_macro reads a long argument into an int variable, which produces a wrong value on big-endian systems. Fix by reading the argument into an intermediate long variable first.
