Hi all,
I am seeing a very strange behavior and I suspect it comes from the
kernel.
I have an application that writes to the network using raw socket:
arp_output = socket(PF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
int r = sendto(arp_output, p->ether_header(), p->size_of_ether_packet(),
0, (sockaddr*)&ip_sock_addr, sizeof(ip_sock_addr));
Once in a while it seems that the kernel is duplicating the packet I am
sending. That is, I call sendto once, but I see two packets with
tcpdump.
Does this make sense to anyone?
