Bug #823
closedSending packet failed on socket 5: Message too long
Added by Laszlo Madarassy almost 11 years ago. Updated over 10 years ago.
Description
Hi,
A new bug (or problem) again:
These errors are displayed on suricata console when traffic goes to the monitored interface:
[5522] 12/6/2013 -- 16:04:15 - (source-af-packet.c:645) <Warning> (AFPWritePacket) -- [ERRCODE: SC_ERR_SOCKET(200)] - Sending packet failed on socket 5: Message too long

Suricata version: latest 1.4-dev from git
MTU is 1500 on both interfaces.
Some traffic is going through, but I don't know what is dropped.

Hello this is a duplicate of #812.
Please try with defrag set to no and disable GRO and other off loading things if needed.

I set defrag to no, but the result is the same.

I've tried to reproduce the issue without success. Can you apply the attached patch to your suricata and run some tests ? This should displays info about the dropped packet.

I have applied the patch and saved the output. It seems an ipv6 packet causes the problem.
You can download the full log from here:

I have sent this traffic to suricata:

The decoding of hexdump in scapy gives some interesting result. This is a packet from vmware to cisco and it is IPv4/TCP. As everything is coherent when compared to information found in the pca file, we can conclude we have something weird here.
Among the weirdness and I think as mentioned by Laszlo before the announced IP packet length is 1648 (anf DF flags is set). This is kind of strange for an interface with a MTU of 1500 (if I'm correct). Laszlo can you confirm we have MTU set to 1500 and that all GRO, GSO are disabled on the capture interface ?
Here's the packet print in scapy:

I've duplicated this behavior in a Debian guest on ESXi 5.1 connected to a Cisco 2970. The fix is to disable generic-receive-offload (GRO) on the two interfaces that af_packet is copying between:
ethtool -K eth1 gro off
ethtool -K eth2 gro off

I've updated Common_Errors to state that GRO needs to be deactivated when AF_PACKET IPS is used.
