You forgot to include the length of sun_len (which happens to be 1)
in addrlen.  Since you're telling the kernel that addr is 1 byte shorter
than it is, it's not surprising that it isn't getting all that you're
trying to send it.

I would just set addrlen to sizeof(struct sockaddr_un).  To be fully
correct, you should probably also set sun_len as well.
