This is a problem for anyone that tries to use a newer version of the librdamcm (like an OFED 1.2 version) with an older kernel (e.g. 2.6.20). As you pointed out, the issue is that the kernel rdma_cm crashes if rdma_init_qp_attr() is called before the user calls rdma_connect(). The problem affects both IB and iWarp. The latest changes to the librdmacm exposed this bug, but the latest kernel multicast code also fixed it. As far as I know, only ABI 3 has been released anywhere. ABI 4 is only available from my git tree. This problem will occur on any code based on ABI 3 or older code snapshots of ABI 4. Hopefully this makes sense. - Sean _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
