[Iwg-arbitration-committee] Arbitration request for Intel QLE7340 & QLE7342 HCAs (Jan 2015 OFA Interop Logo Event)

[Calciano, Jess]

Hello,

Intel would like to file an arbitration request for the January 2015 OFA Interop Logo Event results for the Intel QLE7340 and QLE7342 HCAs.

The provided report (attached for reference) shows two failing tests:

1)      TI NFS over RDMA

2)      TI RSockets

The Intel team has investigated these results and determined that the failures are due to bugs in non-Intel components.

NFSoRDMA:
The failure is due to a known Connectathon issue, documented here:
http://www.spinics.net/lists/linux-nfs/msg16460.html

RSockets:
The issue is that ibv_modify_qp() is failing.  The problem is that an incorrect bit is set in the qp_attr_mask, which is returned from the kernel.  With Intel, bit 21 of the qp_attr_mask is set.  This is not the case for a Mellanox HCA.

Bit 21 is not defined for userspace.  However, it was defined in the kernel as IB_QP_SMAC.

If the librdmacm is modified to mask out this bit, the call succeeds and rstream runs successfully.


Please let me know if the arbitration committee needs any additional information on the analysis.


Thanks,
Jess Calciano
