      RDMA/CMA: add rdma_iw_cm_id() and rdma_res_to_id() helpers · fbdb0a91
      由 Steve Wise 提交于 
      Add a helper function for iwarp drivers to be able to map an
rdma_cm_id to an iw_cm_id.  This is useful for dumping driver specific
NLDEV/RESTRACK connection state.

Add a helper to return the rdma_cm_id pointer from the rdma_restack
pointer.  This is needed for rdma drivers to map a res entry back to
the public rdma_cm_id struct.

      iw_cxgb4: always set iw_cm_id.provider_data · b06f2efd
      由 Steve Wise 提交于 
      In active side connections, the provider_data field is not
getting set.  This will be used in a subsequent patch to dump
state, so always set it.

      RDMA/ipoib: Update paths on CLIENT_REREG/SM_CHANGE events · fa9391db
      由 Doug Ledford 提交于 
      We do a light flush on CLIENT_REREG and SM_CHANGE events.  This goes
through and marks paths invalid. But we weren't always checking for this
validity when we needed to, and so we could keep using a path marked
invalid.  What's more, once we establish a path with a valid ah, we put
a pointer to the ah in the neigh struct directly, so even if we mark the
path as invalid, as long as the neigh has a direct pointer to the ah, it
keeps using the old, outdated ah.

To fix this we do several things.

1) Put the valid flag in the ah instead of the path struct, so when we
put the ah pointer directly in the neigh struct, we can easily check the
validity of the ah on send events.
2) Check the neigh->ah and neigh->ah->valid elements in the needed
places, and if we have an ah, but it's invalid, then invoke a refresh of
the ah.
3) Fix the various places that check for path, but didn't check for
path->valid (now path->ah && path->ah->valid).
