[sr-dev] Re: [kamailio/kamailio] core: local TCP socket is bound on listening address (PR #3925)

@ivanuschak - related to:

``` - *from = &si->su; + memcpy(*from, &si->su, sockaddru_len(si->su)); ```

What I wanted to comment about is that the size are different between the pointer to a structure and the structure itself. A pointer is 4 bytes on 32bit CPU and 8 bytes on 64bit CPU. So the `&si->su` is a pointer (address), being 4/8bytes, `*from` is written with 4/8 bytes.

The change makes the `*from` to be written with `sockaddru_len(si->su)` bytes. Is this correct in the way that `*from` has the proper reserved/allocated size? For me it feels incorrect, the `struct sockaddr_in6` is more than 8 bytes:
