Can I think that every packet (e.g. IP packet) must
have a corresponding creating socket? (i.e. Must every
packet be created by a socket?)

No. ICMP messages come to mind - although I _suppose_ that since those are in response to other traffic, you could claim it was in response to something sent from a "socket" or "endpoint" - depends on how far away you consider it to still be from a socket.


Is there any other way to originate a packet?



Thank you.
