183ecfa309 RDMA/nes: Avoid race between MPA request and reset event to rdma_cm
In passive open, after indicating MPA request to rdma_cm, an incoming
RST would fire a reset event to rdma_cm causing it to crash, since the
current state is not connected.  The solution is to wait for
nes_accept() or nes_reject() before firing the reset event.  If
nes_accept() or nes_reject() is already done, then the reset event
will be fired when RST is processed.

879e5bd5a1 RDMA/nes: Lock down connected_nodes list while processing it
While processing connected_nodes list, we would release the lock when
we need to send reset to remote partner.  That created a window where
the list can be modified.  Change this into a two step process: place
nodes that need processing on a local list then process the local list.

Use nes_free_cqp_request() instead of open coding.  Change some

a list processed in a loop (so continue went to the next item).  Now
it is a single item, so using break is correct.

42ab01c315 IB/mlx4: Fix MTT leakage in resize CQ
When resizing a CQ, MTTs associated with the old CQE buffer were not
freed.  As a result, if any app used resize CQ repeatedly, all MTTs
were eventually exhausted, which led to all memory registration
operations failing until the driver is reloaded.

Once the RESIZE_CQ command returns successfully from FW, FW no longer
accesses the old CQ buffer, so it is safe to deallocate the MTT
entries used by the old CQ buffer.

Finally, if the RESIZE_CQ command fails, the MTTs allocated for the
new CQEs buffer also need to be de-allocated.

This fixes <https://bugs.openfabrics.org/show_bug.cgi?id=1416>.

b3e123cf65 RDMA/cxgb3: Fix deadlock in iw_cxgb3 (hang when configuring interface)
When the iw_cxgb3 module's cxgb3_client "add" func gets called by the
cxgb3 module, the iwarp driver ends up calling the ethtool ops
get_drvinfo function in cxgb3 to get the fw version and other info.
Currently the iwarp driver grabs the rtnl lock around this down call
to serialize.  As of 2.6.27 or so, things changed such that the rtnl
lock is held around the call to the netdev driver open function.  Also
the cxgb3_client "add" function doesn't get called if the device is
down.

So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the
device, the iw_cxgb3 add func gets called with the rtnl_lock held.  If
you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add
func gets called without the rtnl_lock held.  The former causes the
deadlock, the latter does not.

In addition, there are iw_cxgb3 sysfs handlers that also can call down
into cxgb3 to gather the fw and hw versions.  These can be called
concurrently on different processors and at any time.  Thus we need to
push this serialization down in the cxgb3 driver get_drvinfo func.

The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

263c24a2bb IB/ehca: Reject dynamic memory add/remove when ehca adapter is present
Since the ehca device driver does not support dynamic memory add and
remove operations, the driver must explicitly reject such requests in
order to prevent unpredictable behaviors related to existing memory
regions that cover all of memory being used by InfiniBand protocols in
the kernel.

The solution (for now at least) is to add a memory notifier to the
ehca device driver and if a request for dynamic memory add or remove
comes in, ehca will always reject it.  The user can add or remove
memory by hot-removing the ehca adapter, performing the memory
operation, and then hot-adding the ehca adapter back.

19f4282149 IB/ehca: Fix reported max number of QPs and CQs in systems with >1 adapter
Because ehca adapters can differ in the maximum number of QPs and CQs
we have to save the maximum number of these ressources per adapter and
not globally per ehca driver. This fix introduces 2 new members to the
shca structure to store the maximum value for QPs and CQs per adapter.

The module parameters are now used as initial values for those
variables.  If a user selects an invalid number of CQs or QPs we don't
print an error any longer, instead we will inform the user with a
warning and set the values to the respective maximum supported by the
HW.

208dde28b0 IB/mthca: Use pci_request_regions()
Back in prehistoric (pre-git!) days, the kernel's MSI-X support did
request_mem_region() on a device's MSI-X tables, which meant that a
driver that enabled MSI-X couldn't use pci_request_regions() (since
that would clash with the PCI layer's MSI-X request).

However, that was removed (by me!) years ago, so mthca can just use
pci_request_regions() and pci_release_regions() instead of its own
much more complicated code that avoids requesting the MSI-X tables.
