| * IPoIB: Clear high octet in QP numberMichael S. Tsirkin2006-11-16
| | | | | | | | | | | | | | | | | | | | IPoIB assumes that high (reserved) octet in the hardware address is 0, and copies it into the QPN. This violates RFC 4391 (which requires that the high 8 bits are ignored on receive), and will result in an invalid QPN being used when interoperating with IPoIB connected mode.

| * IB/mad: Fix race between cancel and receive completionRoland Dreier2006-11-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When ib_cancel_mad() is called, it puts the canceled send on a list and schedules a "flushed" callback from process context. However, this leaves a window where a receive completion could be processed before the send is fully flushed. This is fine, except that ib_find_send_mad() will find the MAD and return it to the receive processing, which results in the sender getting both a successful receive and a "flushed" send completion for the same request. Understandably, this confuses the sender, which is expecting only one of these two callbacks, and leads to grief such as a use-after-free in IPoIB. Fix this by changing ib_find_send_mad() to return a send struct only if the status is still successful (and not "flushed"). The search of the send_list already had this check, so this patch just adds the same check to the search of the wait_list. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Assure 4K alignment for firmware control blocks in 64K page mode, because kzalloc()'s result address might not be 4K aligned if 64K pages are enabled. Thus, we introduce wrappers called ehca_{alloc,free}_fw_ctrlblock(), which use a slab cache for objects with 4K length and 4K alignment in order to alloc/free firmware control blocks in 64K page mode. In 4K page mode those wrappers just are defines of get_zeroed_page() and free_page(). Signed-off-by: Hoang-Nam Nguyen <hnguyen@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

* IB/cm: Send DREP in response to unmatched DREQSean Hefty2006-10-10
| | | | | | | | | | | | | | | | | Currently a DREP is only sent in response to a DREQ if a connection has been found matching the DREQ, and it is in the proper state. Once a DREP is sent, the local connection moves into timewait. Duplicate DREQs received while in this state result in re-sending the DREP. However, it's likely that the local connection will enter and exit timewait before the remote side times out a lost DREP and resends a DREQ. To handle this, we send a DREP in response to a DREQ, even if a local connection is not found. This avoids maintaining disconnected id's in timewait states for excessively long times, just to handle a lost DREP.

* IB/srp: Enable multiple connections to the same targetIshai Rabinovitz2006-10-10
| | | | | | | | | | | | | | | | | | | Enable multiple concurrent connections to the same SRP target: 1) Use port GUID instead of node GUID in the initiator port identifier. This allows connections to be made from multiple HCA ports at the same time. 2) Let the user specify the identifier extention when adding the device. This allows userspace to make multiple connections even from the same port, if it wants too. Without this, only one connection can be made from any given HCA, even if it has multiple ports, because we don't use multi-channel mode, so targets will only allow one connection from a given initiator port ID.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* RDMA/cma: Fix device removal raceKrishna Kumar2006-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The race is as follows: A process : cma_process_remove() calls cma_remove_id_dev(), which sets id state to CMA_DEVICE_REMOVAL and calls wait_event(dev_remove). B process : cma_req_handler() had incremented dev_remove, and calls cma_acquire_ib_dev() and on failure calls cma_release_remove(), which does a wake_up of cma_process_remove(). Then cma_req_handler() calls rdma_destroy_id(); A Process : cma_remove_id_dev() gets woken and checks the state of id, and since it is still (wrongly) CMA_DEVICE_REMOVAL, it calls notify_user(id) and if that fails, the caller - cma_process_remove() calls rdma_destroy_id(id). Two processes can call rdma_destroy_id(), resulting in one de-referencing kfreed id_priv. Fix is for process B to set CMA_DESTROYING in cma_req_handler() so that process A will return instead of doing a rdma_destroy_id().
