The code that looks like this:

import (
        "errors"
        "net"
        "syscall"
        "unsafe"
)
...skipped...
        if err := getsockopt(fd, syscall.IPPROTO_IP, SO_ORIGINAL_DST, uintptr(unsafe.Pointer(&raw)), uintptr(unsafe.Pointer(&siz))); err != nil {
                return nil, err
        }

fails:

# github.com/Dreamacro/clash/proxy/redir
proxy/redir/tcp_freebsd.go:41:12: undefined: getsockopt

getsockopt is supposed to be found in syscall.

I think there is some confusion here. You are calling a private function. Can you show us a complete minimal code which reproduces this ? Your current version is a redacted snippet.

getsockopt is supposed to be found in syscall.

You say it is supposed to be in syscall, but you are not using the syscall library. Please show us the full code.

Are you looking for syscall.Syscall6 using syscall.SYS_GETSOCKOPT ?

syscall.Syscall6 using syscall.SYS_GETSOCKOPT worked, thanks!
