SubjectRe: Why does struct sock have saddr and daddr?

daddr = destination
saddr = sending address of our end
rcv_saddr = address we bind to

saddr and rcv_saddr may be different as rcv_saddr may be broadcast or
multicast. We do not however use the broadcast/multicast but the interface
address as the source of our packet
