The test script is provided by Kuniyuki in [1], which is used to test the
selection of the TCP reuseport socket problem.

For now, the tcp socket lookup will terminate if the socket is reuse port
in inet_lhash2_lookup(), which makes the socket is not the best match.
For example, we have socket1 and socket2 both listen on "0.0.0.0:1234",
but socket1 bind on "eth0". We create socket1 first, and then socket2.
Then, all

When using GCC on x86-64 to compile an usdt prog with -O1 or higher
optimization, the compiler will generate SIB addressing mode for global
array and PC-relative addressing mode for global variable,
e.g. "1@-96(%rbp,%rax,8)" and "-1@4+t1(%rip)".
The current USDT implementation in libbpf cannot p
On x86-64, USDT arguments can be specified using Scale-Index-Base (SIB)
addressing, e.g. "1@-96(%rbp,%rax,8)". The current USDT implementation
in libbpf cannot parse this format, causing `bpf_program__attach_usdt()`
to fail with -ENOENT (unrecognized register).
This patch fixes this by implementin
