Hello, I am trying to read incoming TCP packets. TCPdump shows that there are packets of size 20-30KB that are arriving.The IP header of these packets has the "Do Not Fragment" flag set to true. When I try to read them from the netfilter queue, I am failing. I am using this command: "status = recv(nfq_fd(_NFQHandle), buf, sizeof(buf), MSG_WAITALL)." Even with MSG_PEEK or MSG_MSG_DONTWAIT, these packets are not being read. I am able to increase the MTU size only upto 9KB. Any packet that is larger than this MTU size is not being read by the recv function. My question is: Is it possible to read un-fragmented packets that are larger than MTU size using the recv function from the netfilter queue?
