2008-09-30IPoIB: Use netif_tx_lock() and get rid of private tx_lock, LLTXRoland Dreier
Currently, IPoIB is an LLTX driver that uses its own IRQ-disabling tx_lock. Not only do we want to get rid of LLTX, this actually causes problems because of the skb_orphan() done with this tx_lock held: some skb destructors expect to be run with interrupts enabled. The simplest fix for this is to get rid of the driver-private tx_lock and stop using LLTX. We kill off priv->tx_lock and use netif_tx_lock[_bh]() instead; the patch to do this is a tiny bit tricky because we need to update places that take priv->lock inside the tx_lock to disable IRQs, rather than relying on tx_lock having already disabled IRQs. Also, there are a couple of places where we need to disable BHs to make sure we have a consistent context to call netif_tx_lock() (since we no longer can use _irqsave() variants), and we also have to change ipoib_send_comp_handler() to call drain_tx_cq() through a timer rather than directly, because ipoib_send_comp_handler() runs in interrupt context and drain_tx_cq() must run in BH context so it can call netif_tx_lock().

2008-09-29IB/mthca: Use pci_request_regions()Roland Dreier
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.

2008-09-25IPoIB: Fix crash when path record fails after path flushRoland Dreier
Commit ee1e2c82 ("IPoIB: Refresh paths instead of flushing them on SM change events") changed how paths are flushed on an SM event. This change introduces a problem if the path record query triggered by fails, causing path->ah to become NULL. A later successful path query will then trigger WARN_ON() in path_rec_completion(), and crash because path->ah has already been freed, so the ipoib_put_ah() inside the lock in path_rec_completion() may actually drop the last reference (contrary to the comment that claims this is safe). Fix this by updating path->ah and freeing old_ah only when the path record query is successful. This prevents the neighbour AH and that path AH from getting out of sync.

2008-09-20IB/ehca: Generate flush status CQ entriesAlexander Schmidt
When a QP goes into error state, it is required that CQ entries with a flush error status are delivered to the application for any outstanding work requests. eHCA does not do this in hardware, so this patch adds software flush CQE generation to the ehca driver. Whenever a QP gets into error state, it is added to the QP error list of its respective CQ. If the error QP list of a CQ is not empty, poll_cq() generates flush CQEs before polling the actual CQ.

2008-09-16IPoIB: Fix deadlock on RTNL between bcast join comp and ipoib_stop()Yossi Etigin
Taking rtnl_lock in ipoib_mcast_join_complete() causes a deadlock with ipoib_stop(). We avoid it by scheduling the piece of code that takes the lock on ipoib_workqueue instead of executing it directly. This works because we only flush the ipoib_workqueue with the RTNL not held. The deadlock happens because ipoib_stop() calls ipoib_ib_dev_down() which calls ipoib_mcast_dev_flush(), which calls ipoib_mcast_free(), which calls ipoib_mcast_leave(). The latter calls ib_sa_free_multicast(), and this waits until the multicast completion handler finishes. This handler is ipoib_mcast_join_complete(), which waits for the rtnl_lock(), which was already taken by ipoib_stop().

2008-08-19IPoIB: Fix deadlock on RTNL in ipoib_stop()Roland Dreier
Commit c8c2afe3 ("IPoIB: Use rtnl lock/unlock when changing device flags") added a call to rtnl_lock() in ipoib_mcast_join_task(), which is run from the ipoib_workqueue. However, ipoib_stop() (which is run inside rtnl_lock()) flushes this workqueue, which leads to a deadlock if the join task is pending. Fix this by simply not flushing the workqueue from ipoib_stop(). It turns out that we really don't care about workqueue tasks running during or after ipoib_stop(), as long as we make sure to flush the workqueue before unregistering a netdev.

2008-08-12IB/ehca: Discard double CQE for one WRAlexander Schmidt
Under rare circumstances, the ehca hardware might erroneously generate two CQEs for the same WQE, which is not compliant to the IB spec and will cause unpredictable errors like memory being freed twice. To avoid this problem, the driver needs to detect the second CQE and discard it. For this purpose, introduce an array holding as many elements as the SQ of the QP, called sq_map. Each sq_map entry stores a "reported" flag for one WQE in the SQ. When a work request is posted to the SQ, the respective "reported" flag is set to zero. After the arrival of a CQE, the flag is set to 1, which allows to detect the occurence of a second CQE. The mapping between WQE / CQE and the corresponding sq_map element is implemented by replacing the lowest 16 Bits of the wr_id with the index in the queue map. The original 16 Bits are stored in the sq_map entry and are restored when the CQE is passed to the application.

In consequence, the return value of idr_find() must be checked and the CQE must be discarded when the QP cannot be found.

2008-08-12IB/ehca: Update qp_state on cached modify_qp()Alexander Schmidt
Since the introduction of the port auto-detect mode for ehca, calls to modify_qp() may be cached in the device driver when the ports are not activated yet. When a modify_qp() call is cached, the qp state remains untouched until the port is activated, which will leave the qp in the reset state. In the reset state, however, it is not allowed to post SQ WQEs, which confuses applications like ib_mad. The solution for this problem is to immediately set the qp state as requested by modify_qp(), even when the call is cached.

2008-08-04RDMA/cxgb3: Fix deadlock initializing iw_cxgb3 deviceSteve Wise
Running 'ifconfig up' on the cxgb3 interface with iw_cxgb3 loaded causes a deadlock. The rtnl lock is already held in this path. The function fw_supports_fastreg() was introduced in 2.6.27 to conditionally set the IB_DEVICE_MEM_MGT_EXTENSIONS bit iff the firmware was at 7.0 or greater, and this function also acquires the rtnl lock and which thus causes a deadlock. Further, if iw_cxgb3 is loaded _after_ the nic interface is brought up, then the deadlock does not occur and therefore fw_supports_fastreg() does need to grab the rtnl lock in that path. It turns out this code is all useless anyway. The low level driver will NOT allow the open if the firmware isn't 7.0, so iw_cxgb3 can always set the MEM_MGT_EXTENSIONS bit. Simplify...
