RDMA_Connect issue on Windows

RDMA_Connect issue on Windows

[muthu crazy]

Dear All,

I am trying to make a fabrics setup using Chelsio RNIC where Windows
is the Client PC, and Linux is the target PC. From Windows Client
driver, I am invoking NDKConnect API(It will internally call
RMDA_Connect) and passing below structures as a parameter to it.

struct RDMA_CONN_PARAM
{
RDMA_CM_REQUEST private_data;
private_data_len = sizeof(RDMA_CM_REQUEST)
responder_resources = 0x20
initiator_depth = 0
flow_control=1
retry_count=7
RNR_Retry_count = 7
SRQ = 0
QP_num = 0x400
}

struct RDMA_CM_REQUEST
{
Recfmt = 0
Qid = 0
Hrqsize = 0x20
Hsqsize = 0x20
Reserved[8:31] = 0;
}

but on target side, I could see some junk value along with my actual
data received.(Linux Kernel:4.9.8)

like below:

0xFFFFFFE0, 0xFFFFFFB0, 0x23, 0x6, 0x0, 0xFFFFFFE0, 0xFFFFFFFF
0x20,0x20,0x0,0x1,0x7,0x7,0x0,0x0,0x0,0x4

Has anybody observed this before? Please help me out.


Thanks,
--Muthu

RDMA_Connect issue on Windows

[Max Gurtovoy]

I would also try to parse it with Wireshark and compare all the needed 
fields and sizes.
We are adding more and more nvmf command parsing to the disector but 
you're in earliar stage of RDMA connection establisment.

RDMA_Connect issue on Windows

[muthu crazy]

Thanks for the reply,

I was trying to see the packets in Wireshark(2.2.6) during
rdma_connect but I was getting only ARP packets. Do I need to add any
plugin for Wireshark? Or any protocol preference has to be added in
settings?

please use this link:
https://www.wireshark.org/download.html
and download the latest development release.
make sure your listener port is 4420.

Dear Robert,

Could you please guide me what has to be passed as part of NDKConnect,
I tried with RequestPrivateData structure. but it didn't work out.
Since MSDN was not clear, I was unable to proceed further.

Please help me out.

[Suspected-Phishing]Re: RDMA_Connect issue on Windows

[Arka Sharma]

I have installed wireshark 2.2.7. I fund that under Analyze->Enabled
Protocols both iwarp_rdmap_ddp and iwarp_mpa enabled. I have also set
the port no to 4420 at the target side. But all I can capture during
Rdma connect is ARP. Also at the target side I capture only ARP using
tcpdump. Do I need to use wd_tcpdump_trace and wd_sniffer at target
side ?

Thanks,
Arka
