2012-01-27RDMA/ucma: Discard all events for new connections until acceptedSean Hefty
After reporting a new connection request to user space, the rdma_ucm will discard subsequent events until the user has associated a user space idenfier with the kernel cm_id. This is needed to avoid reporting a reject/disconnect event to the user for a request that they may not have processed. The user space identifier is set once the user tries to accept the connection request. However, the following race exists in ucma_accept(): ctx->uid = cmd.uid; <events may be reported now> ret = rdma_accept(ctx->cm_id, ...); Once ctx->uid has been set, new events may be reported to the user. While the above mentioned race is avoided, there is an issue that the user _may_ receive a reject/disconnect event if rdma_accept() fails, depending on when the event is processed. To simplify the use of rdma_accept(), discard all events unless rdma_accept() succeeds. This problem was discovered based on questions from Roland Dreier <roland@purestorage.com>.

Commit 8d4548f2b ("IB/qib: Default some module parameters optimally") introduced an issue with older root complexes. They cannot handle the pcie_caps of 0x51 (MaxReadReq 4096, MaxPayload=256). A typical diagnostic in this situation reported by syslog contains the text: [PCIe Poisoned TLP][Send DMA memory read] Restore the module paramter default to zero with will avoid any changes in the root complex.

2012-01-27RDMA/core: Fix kernel panic by always initializing qp->usecntBernd Schubert
We have just been investigating kernel panics related to cq->ibcq.event_handler() completion calls. The problem is that ib_destroy_qp() fails with -EBUSY. Further investigation revealed qp->usecnt is not initialized. This counter was introduced in linux-3.2 by commit 0e0ec7e0638e ("RDMA/core: Export ib_open_qp() to share XRC TGT QPs") but it only gets initialized for IB_QPT_XRC_TGT, but it is checked in ib_destroy_qp() for any QP type. Fix this by initializing qp->usecnt for every QP we create.

SMP system Sequence is as follows: 1.suppose current task is A. start schedule() 2.task A is enqueued pushable task at the entry of schedule() __schedule prev = rq->curr; ... put_prev_task put_prev_task_rt enqueue_pushable_task 4.pick the task B as next task. next = pick_next_task(rq); 3.rq->curr set to task B and context_switch is started. rq->curr = next; 4.At the entry of context_swtich, release this cpu's rq->lock. context_switch prepare_task_switch prepare_lock_switch raw_spin_unlock_irq(&rq->lock); 5.Shortly after rq->lock is released, interrupt is occurred and start IRQ context 6.try_to_wake_up() which called by ISR acquires rq->lock try_to_wake_up ttwu_remote rq = __task_rq_lock(p) ttwu_do_wakeup(rq, p, wake_flags); task_woken_rt 7.push_rt_task picks the task A which is enqueued before. task_woken_rt push_rt_tasks(rq) next_task = pick_next_pushable_task(rq) 8.At find_lock_lowest_rq(), If double_lock_balance() returns 0, lowest_rq can be the remote rq. (But,If preemption is on, double_lock_balance always return 1 and it does't happen.) push_rt_task find_lock_lowest_rq if (double_lock_balance(rq, lowest_rq)).. 9.find_lock_lowest_rq return the available rq. task A is migrated to the remote cpu/rq. push_rt_task ... deactivate_task(rq, next_task, 0); set_task_cpu(next_task, lowest_rq->cpu); activate_task(lowest_rq, next_task, 0); 10. But, task A is on irq context at this cpu. So, task A is scheduled by two cpus at the same time until restore from IRQ. Task A's stack is corrupted. To fix it, don't migrate an RT task if it's still running.

2012-01-27perf: Fix broken interrupt rate throttlingStephane Eranian
This patch fixes the sampling interrupt throttling mechanism. It was broken in v3.2. Events were not being unthrottled. The unthrottling mechanism required that events be checked at each timer tick. This patch solves this problem and also separates: - unthrottling - multiplexing - frequency-mode period adjustments Not all of them need to be executed at each timer tick. This third version of the patch is based on my original patch + PeterZ proposal (https://lkml.org/lkml/2012/1/7/87). At each timer tick, for each context: - if the current CPU has throttled events, we unthrottle events - if context has frequency-based events, we adjust sampling periods - if we have reached the jiffies interval, we multiplex (rotate) We decoupled rotation (multiplexing) from frequency-mode sampling period adjustments. They should not necessarily happen at the same rate. Multiplexing is subject to jiffies_interval (currently at 1 but could be higher once the tunable is exposed via sysfs). We have grouped frequency-mode adjustment and unthrottling into the same routine to minimize code duplication. When throttled while in frequency mode, we scan the events only once. We have fixed the threshold enforcement code in __perf_event_overflow(). There was a bug whereby it would allow more than the authorized rate because an increment of hwc->interrupts was not executed at the right place. The patch was tested with low sampling limit (2000) and fixed periods, frequency mode, overcommitted PMU. On a 2.1GHz AMD CPU: $ cat /proc/sys/kernel/perf_event_max_sample_rate 2000 We set a rate of 3000 samples/sec (2.1GHz/3000 = 700000): $ perf record -e cycles,cycles -c 700000 noploop 10 $ perf report -D | tail -21 Aggregated stats: TOTAL events: 80086 MMAP events: 88 COMM events: 2 EXIT events: 4 THROTTLE events: 19996 UNTHROTTLE events: 19996 SAMPLE events: 40000 cycles stats: TOTAL events: 40006 MMAP events: 5 COMM events: 1 EXIT events: 4 THROTTLE events: 9998 UNTHROTTLE events: 9998 SAMPLE events: 20000 cycles stats: TOTAL events: 39996 THROTTLE events: 9998 UNTHROTTLE events: 9998 SAMPLE events: 20000 For 10s, the cap is 2x2000x10 = 40000 samples.

2012-01-27sched: Fix ancient race in do_exit()Yasunori Goto
try_to_wake_up() has a problem which may change status from TASK_DEAD to TASK_RUNNING in race condition with SMI or guest environment of virtual machine. As a result, exited task is scheduled() again and panic occurs. Here is the sequence how it occurs: ----------------------------------+----------------------------- | CPU A | CPU B ----------------------------------+----------------------------- TASK A calls exit().... do_exit() exit_mm() down_read(mm->mmap_sem); rwsem_down_failed_common() set TASK_UNINTERRUPTIBLE set waiter.task <= task A list_add to sem->wait_list : raw_spin_unlock_irq() (I/O interruption occured) __rwsem_do_wake(mmap_sem) list_del(&waiter->list); waiter->task = NULL wake_up_process(task A) try_to_wake_up() (task is still TASK_UNINTERRUPTIBLE) p->on_rq is still 1.) ttwu_do_wakeup() (*A) : (I/O interruption handler finished) if (!waiter.task) schedule() is not called due to waiter.task is NULL. tsk->state = TASK_RUNNING : check_preempt_curr(); : task->state = TASK_DEAD (*B) <--- set TASK_RUNNING (*C) schedule() (exit task is running again) BUG_ON() is called! -------------------------------------------------------- The execution time between (*A) and (*B) is usually very short, because the interruption is disabled, and setting TASK_RUNNING at (*C) must be executed before setting TASK_DEAD. HOWEVER, if SMI is interrupted between (*A) and (*B), (*C) is able to execute AFTER setting TASK_DEAD! Then, exited task is scheduled again, and BUG_ON() is called.... If the system works on guest system of virtual machine, the time between (*A) and (*B) may be also long due to scheduling of hypervisor, and same phenomenon can occur. By this patch, do_exit() waits for releasing task->pi_lock which is used in try_to_wake_up(). It guarantees the task becomes TASK_DEAD after waking up.

2012-01-27ARM: SAMSUNG: Fix missing api-change from subsys_interface changeHeiko Stuebner
Commit 4a858cfc9a (arm: convert sysdev_class to a regular subsystem) converted the samsung sysdevs into subsys_interface instances. While the original add-function only had a (struct sys_device *) parameter, the dev_add from subsys_interface needs (struct device *, struct subsys_interface *) leading to "initialized from incompatible pointer type" warnings.

2012-01-27ARM: SAMSUNG: Fix platform data setup for I2C adapter 0Sylwester Nawrocki
The common static default_i2c_data structure gets bus_num set by each s3c_i2c?_set_platdata() call, except for s3c_i2c0_set_platdata(). Thus if for instance s3c_i2c1_set_platdata() is called prior to s3c_i2c0_set_platdata() the I2C0 controller has bus_num set to wrong value of 1, i.e. the one from previous set_platdata call. Fix this by also setting bus_num for I2C0.

2012-01-27ARM: S3C6410: Use device names for both I2C clocksMark Brown
When the S3C64xx CPUs were converted to clkdev mappings were added for the I2C controllers on them. On S3C6410 a device name is specified for I2C controller 1 but not for controller 0 which makes the code less robust as we'll falsely return the clock for controller 0 if there's an error in the request for controller 1. Improve things by registering a device name for controller 0 as well. Due to the fact that we change the numbering for controller 0 depending on if we've registered controller 1 this requires an ifdef to choose the name.
