workqueue: deprecate __cancel_delayed_work()

2012-08-21T20:18:24Z

Now that cancel_delayed_work() can be safely called from IRQ handlers, there's no reason to use __cancel_delayed_work(). Use cancel_delayed_work() instead of __cancel_delayed_work() and mark the latter deprecated. Signed-off-by: Tejun Heo Acked-by: Jens Axboe Cc: Jiri Kosina Cc: Roland Dreier Cc: Tomi Valkeinen

workqueue: use mod_delayed_work() instead of __cancel + queue

2012-08-21T20:18:24Z

Now that mod_delayed_work() is safe to call from IRQ handlers, __cancel_delayed_work() followed by queue_delayed_work() can be replaced with mod_delayed_work(). Most conversions are straight-forward except for the following. * net/core/link_watch.c: linkwatch_schedule_work() was doing a quite elaborate dancing around its delayed_work. Collapse it such that linkwatch_work is queued for immediate execution if LW_URGENT and existing timer is kept otherwise. Signed-off-by: Tejun Heo Cc: "David S. Miller" Cc: Tomi Valkeinen

IB/mad: Don't send response for failed MADs

2012-04-24T23:08:57Z

Commit 0b307043049f ("IB/mad: Return error response for unsupported MADs") does not failed MADs (eg those that return IB_MAD_RESULT_FAILURE) properly -- these MADs should be silently discarded. (We should not force the lower-layer drivers to return SUCCESS | CONSUMED in this case, since the MAD is NOT successful). Unsupported MADs are not failures -- they return SUCCESS, but with an "unsupported error" status value inside the response MAD.

IB/mad: Set 'D' bit in response for unhandled MADs

2012-04-24T23:06:50Z

Commit 0b307043049f ("IB/mad: Return error response for unsupported MADs") does not handle directed-route MADs properly -- it fails to set the 'D' bit in the response MAD status field. This is a problem for SmInfo MADs when the receiver does not have an SM running. Reviewed-by: Hal Rosenstock Signed-off-by: Jack Morgenstein Signed-off-by: Roland Dreier

IB/mad: Return error response for unsupported MADs

infiniband: Fix up module files that need to include module.h

2011-10-31T23:31:35Z

They had been getting it implicitly via device.h but we can't rely on that for the future, due to a pending cleanup so fix it now. Signed-off-by: Paul Gortmaker

IB/mad: Verify mgmt class in received MADs

2011-10-06T16:33:05Z

If a received MAD contains an invalid or reserved mgmt class, we will attempt to access method_table outside of its range. Add a check to ensure that mgmt class falls within the handled range. Found by code inspection. Signed-off-by: Sean Hefty Signed-off-by: Roland Dreier

IB/mad: Return EPROTONOSUPPORT when an RDMA device lacks the QP required

2011-05-23T18:15:48Z

We had a script which was looping through the devices returned from ibstat and attempted to register a SMI agent on an ethernet device. This caused a kernel panic for IBoE devices that don't have QP0. Fix this by checking if the QP exists before using it. Signed-off-by: Ira Weiny Acked-by: Sean Hefty Signed-off-by: Roland Dreier

IB/mad: IBoE supports only QP1 (no QP0)

2010-10-13T16:38:11Z

Since IBoE is using Ethernet as its link layer, there is no central management entity so there is need for QP0. QP1 is still needed since it handles communications between CM agents. This patch will skip QP0 and create only QP1 for IBoE ports. Signed-off-by: Eli Cohen Signed-off-by: Roland Dreier
