[ofa-general] SDP and iWARP in OFED 1.2?

[Craig Prescott]

Hi;

I am trying run the netperf SDP_STREAM test between a
pair of Chelsio S310-SR iWARP cards in x86_64 hosts
(CentOS 5.0, OFED 1.2).

My netperf client command starts like so:

[root at tebow1 ~]# LD_PRELOAD=/usr/lib64/libsdp.so 
/opt/netperf/bin/netperf -l 10 -H xx.xx.xx.xx -L yy.yy.yy.yy -c -C -t 
SDP_STREAM
SDP STREAM TEST from yy.yy.yy.yy (yy.yy.yy.yy) port 0 AF_INET to 
xx.xx.xx.xx (xx.xx.xx.xx) port 0 AF_INET

And then the client panics.  The RIP on the console refers to
ib_sdp:sdp_connected_handler, and I can see rdma_cm:cma_iw_handler
and iw_cm:cm_work_handler in the traceback.  From strace on the
client, the last output I get is:

connect(8, {sa_family=AF_INET, sin_port=htons(12865), 
sin_addr=inet_addr("128.227.253.92")}, 128

I can see the connection on the netserver host in sdpnetstat:

Proto Recv-Q Send-Q Local Address           Foreign Address
sdp        0      0 xx.xx.xx.xx:51804       yy.yy.yy.yy:48590

My libsdp.conf on both hosts is very simple:

use both server * *:*
use both client * *:*

The hosts I'm using also have 4X SDR IB HCAs (mthca),
if that matters.  The SDP_STREAM test runs perfectly
over IB.

Is SDP on iWARP supposed to work in OFED 1.2?  Any advice
or hints on getting it working would be most appreciated.

Thanks,
Craig
