2008-10-22IB/ehca: Reject dynamic memory add/remove when ehca adapter is presentStefan Roscher
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.

2008-10-22IB/ehca: Fix reported max number of QPs and CQs in systems with >1 adapterStefan Roscher
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.

2008-10-22mlx4_core: Multiple port type supportYevgeny Petrilin
Multi-protocol adapters support different port types. Each consumer of mlx4_core queries for supported port types; in particular mlx4_ib can no longer assume that all physical ports belong to it. Port type is configured through a sysfs interface. When the type of a port is changed, all mlx4 interfaces are unregistered, and then registered again with the new port types.

2008-10-20x86: sysfs: kill owner field from attributeParag Warudkar
Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs attribute->owner unnecessary. But the field was left in the structure to ease the merge. It's been over a year since that change and it is now time to start killing attribute->owner along with its users - one arch at a time! This patch is attempt #1 to get rid of attribute->owner only for CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on as and when possible - avr32 will be the next since that is something I can test. Compile (make allyesconfig / make allmodconfig / custom config) and boot tested. akpm: the idea is that we put the declaration of sttribute.owner inside `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because new usages kept on turning up in subsystem trees.

This is a much better version of a previous patch to make the parser tables constant.

2008-10-13[SCSI] libiscsi: rename host reset to target resetMike Christie
I had this in my patchset to add target reset support, but it got dropped due to patching conflicts. This initial patch just renames the function and users. We are actually just dropping the session, and so this does not have anything to do with the host exactly. It does for software iscsi because we allocate a host per session, but for cxgb3i this makes no sense.

2008-10-13[SCSI] libiscsi: Support drivers initiating session removalMike Christie
If the driver knows when hardware is removed like with cxgb3i, bnx2i, qla4xxx and iser then we will want to remove the sessions/devices that are bound to that device before removing the host. cxgb3i and in the future bnx2i will remove the host and that will remove all the sessions on the hba. iser can call iscsi_kill_session when it gets an event that indicates that a hca is removed. And when qla4xxx is hooked in to the lib (it is only hooked into the class right now) it can call iscsi remove host like the partial offload card drivers.

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.

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.
