2009-10-07RDMA/iwcm: Don't call provider reject func with irqs disabledSteve Wise1-0/+2
In commit cb58160e ("RDMA/iwcm: Reject the connection when the cm_id is destroyed") a call to the provider's reject handler was added to destroy_cm_id() to fix a provider endpoint leak. This call needs to be done with interrupts enabled. So unlock and relock around this call. This is safe because: 1) the provider will do nothing with this endpoint until the iwcm either accepts or rejects. 2) the lock is only released after the iwcm state is changed, so an errant iwcm app that is destroying -and- rejecting the connection concurrently will get a failure on one of the calls.

2009-09-24IPoIB: Don't turn on carrier for a non-active portMoni Shoua1-0/+7
Multicast joins can succeed even if the IB port is down. This happens when the SM runs on the same port with the requesting port. However, IPoIB calls netif_carrier_on() when the join of the broadcast group succeeds, without caring about the state of the IB port. The result is an IPoIB interface in RUNNING state but without an active IB port to support it. If a bonding interface uses this IPoIB interface as a slave it might not detect that this slave is almost useless and failover functionality will be damaged. The fix checks the state of the IB port in the carrier_task before calling netif_carrier_on().

2009-09-23IB/mad: Fix lock-lock-timer deadlock in RMPP codeRoland Dreier1-4/+13
Holding agent->lock across cancel_delayed_work() (which does del_timer_sync()) in ib_cancel_rmpp_recvs() leads to lockdep reports of possible lock-timer deadlocks if a consumer ever does something that connects agent->lock to a lock taken in IRQ context (cf http://marc.info/?l=linux-rdma&m=125243699026045). Fix this by changing the list items to a new state "CANCELING" while holding the lock, and then canceling the delayed work without holding the lock. If the delayed work runs after the lock is dropped, it will see the state is CANCELING and return immediately, so the list will stay stable while we traverse it with the lock not held.

2009-09-23walk system ram rangeKAMEZAWA Hiroyuki1-1/+1
Originally, walk_memory_resource() was introduced to traverse all memory of "System RAM" for detecting memory hotplug/unplug range. For doing so, flags of IORESOUCE_MEM|IORESOURCE_BUSY was used and this was enough for memory hotplug. But for using other purpose, /proc/kcore, this may includes some firmware area marked as IORESOURCE_BUSY | IORESOUCE_MEM. This patch makes the check strict to find out busy "System RAM". Note: PPC64 keeps their own walk_memory_resouce(), which walk through ppc64's lmb informaton. Because old kclist_add() is called per lmb, this patch makes no difference in behavior, finally. And this patch removes CONFIG_MEMORY_HOTPLUG check from this function. Because pfn_valid() just show "there is memmap or not* and cannot be used for "there is physical memory or not", this function is useful in generic to scan physical memory range.

2009-09-07IB/mad: Fix possible lock-lock-timer deadlockRoland Dreier1-3/+3
Lockdep reported a possible deadlock with cm_id_priv->lock, mad_agent_priv->lock and mad_agent_priv->timed_work.timer; this happens because the mad module does cancel_delayed_work(&mad_agent_priv->timed_work); while holding mad_agent_priv->lock. cancel_delayed_work() internally does del_timer_sync(&mad_agent_priv->timed_work.timer). This can turn into a deadlock because mad_agent_priv->lock is taken inside cm_id_priv->lock, so we can get the following set of contexts that deadlock each other: A: holding cm_id_priv->lock, waiting for mad_agent_priv->lock B: holding mad_agent_priv->lock, waiting for del_timer_sync() C: interrupt during mad_agent_priv->timed_work.timer that takes cm_id_priv->lock Fix this by using the new __cancel_delayed_work() interface (which internally does del_timer() instead of del_timer_sync()) in all the places where we are holding a lock.

2009-09-05RDMA/nes: Allocate work item for disconnect event handlingDon Wood2-17/+16

2009-09-05IB/mthca: Don't allow userspace open while recovering from catastrophic errorJack Morgenstein4-0/+7
Userspace apps are supposed to release all ib device resources if they receive a fatal async event (IBV_EVENT_DEVICE_FATAL). However, the app has no way of knowing when the device has come back up, except to repeatedly attempt ibv_open_device() until it succeeds. However, currently there is no protection against the open succeeding while the device is in being removed following the fatal event. In this case, the open will succeed, but as a result the device waits in the middle of its removal until the new app releases its resources -- and the new app will not do so, since the open succeeded at a point following the fatal event generation. This patch adds an "active" flag to the device. The active flag is set to false (in the fatal event flow) before the "fatal" event is generated, so any subsequent ibv_dev_open() call to the device will fail until the device comes back up, thus preventing the above deadlock.
