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.

When two md arrays share some block device (e.g each uses different partitions on the one device), a resync of one array will wait for the resync on the other to finish. This can be a long time and as it currently waits TASK_UNINTERRUPTIBLE, the softlockup code notices and complains.

2008-09-18bnx2: Promote vector field in bnx2_irq structure from u16 to unsigned intBenjamin Li
The bnx2 driver stores/uses the irq value from the pci_dev internally. But when it stores the irq value, it has been performing an integer demotion. Because of the recent changes made to arch/x86/kernel/io_apic.c, the new method in creating the irq value (using build_irq_for_pci_dev()) has exposed this bug on x86 systems. Because of this demotion when calling request_irq() from bnx2_request_irq(), the driver would get a return code of -EINVAL. This is because the kernel could not find the requested irq descriptor. By storing the irq value properly, the kernel can find the correct irq descriptor and the bnx2 driver can operate normally.

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(). This bug was introduced in commit a77a57a1 ("IPoIB: Fix deadlock on RTNL in ipoib_stop()"). Signed-off-by: Yossi Etigin <yosefe@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

Byte swap the addresses in the page list for fast register work requests to big endian to match what the HCA expectx. Also, the addresses must have the "present" bit set so that the HCA knows it can access them. Otherwise the HCA will fault the first time it accesses the memory region.

2008-09-14crypto: talitos - Avoid consecutive packets going out with same IVKim Phillips
The SEC's h/w IV out implementation DMAs the trailing encrypted payload block of the last encryption to ctx->iv. Since the last encryption may still be pending completion, we can sufficiently prevent successive packets from being transmitted with the same IV by xoring with sequence number. Also initialize alg_list earlier to prevent oopsing on a failed probe.
