Dear all, I'm writing a network analyzer software using Linux and I need a VERY precise frame time stamping. Therefor I am planing to add my own time stamping algorithm on a modified network driver. For test purpose I did so : skb->tstamp.tv64 = 0x00010002; netif_rx(skb); On the user side, I ask for the timestamp that way : ... sock = socket(AF_PACKET, SOCK_RAW, type); ... //bind this socket with the interface using my modified driver. ... recvByteCount = recv(sock, buffer, 1514, 0); ioctl(sock, SIOCGSTAMP, &timeStamp); I was surprised to see that the var timeStamp was still holding a count of second since year 1970. Investigating a bit into the kernel code, I found that ioctl(sock, SIOCGSTAMP, ...) was giving just the current kernel time using ktime_get_real(). Are my investigation wrong ? Is that a bug in kernel code ? Is there an other way to access skb.tstamp from user side ? Thank's to any one that can help me !
