I tried to get the ipv6 address of accessor, but GetSockOpt for OriginalDst only supports ipv4. Can you add ipv6 support?
Or is there any substitute?

Unfortunately SO_ORIGINAL_DST is undocumented in Linux. I don't know if Linux even supports it for IPv6 sockets. If you can find documentation that says Linux does, then we can add IPv6 support for it to Nix.

But as for your immediate problem, have you considered whether getsockname or getpeername will work?

No.
Argument type for the two functions is fd: RawFd which means int32 . However, ipv6 address is int128 .
It seems that many functions in nix::sys::socket may have this problem.

BTW, the code with problem is here

A variable of type RawFd should never be used to hold an IP address! It's for file descriptors. Those two functions return SockAddr, which may be IPv4 or IPv6.
