Hello,
I do not know if this is the right place to report a possible issue, but I
was not able to find another list related to the problem I am experiencing.
I am currently using two different hardware devices, using two different
Intel drivers (e1000e - system 1 - and igb - system 2 -) and the problem is
occuring in both.
Here is a compiled bug reporting form:
[1.] One line summary of the problem:
No hardware receive timestamps are returned when using ETH_P_ALL raw
sockets and Intel NICs
[2.] Full description of the problem/report:
I am currently using raw sockets with ETH_P_ALL, in order to capture all
the packets coming from my ethernet NIC, together with hardware
timestamping (set by using the SO_TIMESTAMPING socket option).
In particular, I set up everything as in the code reported in the example
program (point [7. ]).
I create a socket with:
socket(AF_PACKET,SOCK_RAW,htons(ETH_P_ALL))
Then, I enable hardware timestamps by calling the proper ioctl:
ioctl(sock,SIOCSHWTSTAMP,&hwtstamp)
and by setting:
flags=SOF_TIMESTAMPING_RX_HARDWARE | SOF_TIMESTAMPING_TX_HARDWARE |
SOF_TIMESTAMPING_RAW_HARDWARE;
setsockopt(sock,SOL_SOCKET,SO_TIMESTAMPING,&flags,sizeof(flags))
Everything is performed according to the timestaping documentation:
https://www.kernel.org/doc/Documentation/networking/timestamping.txt
Hardware timestamps should be reported as ancillary data. If ETH_P_ALL is
set, no timestamps are reported and mhdr.msg_controllen (from struct msghdr
mhdr) is always 0, after each recvmsg.
Sometimes, only the first received packet timestamp is reported, but all
the others are not.
If other protocols are set, such as ETH_P_IP, timestamps are correctly
reported:
socket(AF_PACKET,SOCK_RAW,htons(ETH_P_IP))
Hardware: system 1: Intel Corporation Ethernet Connection (4) I219-V (rev
21) - e1000e
system 2: Intel Corporation I210 Gigabit Network Connection (rev 03)
[3.] Keywords (i.e., modules, networking, kernel):
networking, timestamps, timestamping, sockets, AF_PACKET, ETH_P_ALL,
ETH_P_IP, CSMG, ancillary data, SOF_TIMESTAMPING_RAW_HARDWARE, Intel NIC
