i40iw: Use correct src address in memcpy to rdma stats counters

2017-01-09T07:32:24+00:00

commit 91c42b72f8e8b45961ff05a05009b644e6316ca2 upstream.

hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats().
Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats
data into rdma_hw_stats counters.

IB/rxe: Fix a memory leak in rxe_qp_cleanup()

2017-01-09T07:32:23+00:00

commit e259934d4df7f99f2a5c2c4f074f6a55bd4b1722 upstream.

A socket is associated with every QP by the rxe driver but sock_release()
is never called. Add a call to sock_release() in rxe_qp_cleanup().

IB/multicast: Check ib_find_pkey() return value

2017-01-09T07:32:23+00:00

commit d3a2418ee36a59bc02e9d454723f3175dcf4bfd9 upstream.

This patch avoids that Coverity complains about not checking the
ib_find_pkey() return value.

IPoIB: Avoid reading an uninitialized member variable

IB/mad: Fix an array index check

2017-01-09T07:32:23+00:00

commit 2fe2f378dd45847d2643638c07a7658822087836 upstream.

The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS
(80) elements. Hence compare the array index with that value instead
of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity
reports the following:

Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).

Pull rmda fixes from Doug Ledford.
 "First round of -rc fixes.

  Due to various issues, I've been away and couldn't send a pull request
  for about three weeks. There were a number of -rc patches that built
  up in the meantime (some where there already from the early -rc
  stages). Obviously, there were way too many to send now, so I tried to
  pare the list down to the more important patches for the -rc cycle.

  Most of the code has had plenty of soak time at the various vendor's
  testing setups, so I doubt there will be another -rc pull request this
  cycle. I also tried to limit the patches to those with smaller
  footprints, so even though a shortlog is longer than I would like, the
  actual diffstat is mostly very small with the exception of just three
  files that had more changes, and a couple files with pure removals.

  Summary:
   - Misc Intel hfi1 fixes
   - Misc Mellanox mlx4, mlx5, and rxe fixes
   - A couple cxgb4 fixes"

iw_cxgb4: invalidate the mr when posting a read_w_inv wr

2016-11-17T01:10:36+00:00

Also, rearrange things a bit to have a common c4iw_invalidate_mr()
function used everywhere that we need to invalidate.

iw_cxgb4: set *bad_wr for post_send/post_recv errors

2016-11-17T01:10:36+00:00

There are a few cases in c4iw_post_send() and c4iw_post_receive()
where *bad_wr is not set when an error is returned.  This can
cause a crash if the application tries to use bad_wr.
