2019-12-02wimax: i2400: Fix memory leak in i2400m_op_rfkill_sw_toggleNavid Emamdoost
commit 6f3ef5c25cc762687a7341c18cbea5af54461407 upstream. In the implementation of i2400m_op_rfkill_sw_toggle() the allocated buffer for cmd should be released before returning. The documentation for i2400m_msg_to_dev() says when it returns the buffer can be reused. Meaning cmd should be released in either case. Move kfree(cmd) before return to be reached by all execution paths.

commit 057b8945f78f76d0b04eeb5c27cd9225e5e7ad86 upstream. In fsl_lpspi_probe an SPI controller is allocated either via spi_alloc_slave or spi_alloc_master.

2019-12-02media: vivid: Fix wrong locking that causes race conditions on streaming stopAlexander Popov
commit 6dcd5d7a7a29c1e4b8016a06aed78cd650cd8c27 upstream. There is the same incorrect approach to locking implemented in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out() and sdr_cap_stop_streaming(). These functions are called during streaming stopping with vivid_dev.mutex locked. And they all do the same mistake while stopping their kthreads, which need to lock this mutex as well. See the example from vivid_stop_generating_vid_cap(): /* shutdown control thread */ vivid_grab_controls(dev, false); mutex_unlock(&dev->mutex); kthread_stop(dev->kthread_vid_cap); dev->kthread_vid_cap = NULL; mutex_lock(&dev->mutex); But when this mutex is unlocked, another vb2_fop_read() can lock it instead of vivid_thread_vid_cap() and manipulate the buffer queue. That causes a use-after-free access later. To fix those issues let's: 1. avoid unlocking the mutex in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out() and sdr_cap_stop_streaming(); 2. use mutex_trylock() with schedule_timeout_uninterruptible() in the loops of the vivid kthread handlers.

Hence avoid repopulating them for every SQE, this saves few cycles.

2019-11-26perf/smmuv3: Fix programming event type with globalBharat Bhushan
commit 439fc228868bd8f8b8f1cda07f343bf3579af58b from git@git.assembla.com:cavium/WindRiver.linux.git filtering Currently SMMU_PMCG_EVTYPERn.EVENT (event type) for n > 0 is not programmed on implementation supporting global filtering. It uses default initialized values and reports counter of default event-type rather than requested event-type. Also SMMU_PMCG_EVTYPERn.SPAN and SMMU_PMCG_SMR(n) is RES0 for n > 0, so program these as zero for n > 0.

2019-11-26octeontx2-pf: Alloc only used MSIX vectorsSunil Goutham
commit c94525c3a9b0e992be718aa5dc214bdda0ebd3b8 from git@git.assembla.com:cavium/WindRiver.linux.git Each of the CGX mapped RVU PFVF has 210 MSIX vectors and kernel globally support only 8192 IRQs. So enabling 210 vectors for all PF, their VFs and LBKVFs results in failure of pci_alloc_vectors for some of the devices. Increasing the Linux IRQ count from 8192 has upstream depencency and for reasons unknown resulted in performance regression on Armada silicon. Since netdev drivers are not registering NPA block IRQs, reverse the NPA and NIX MSIX vectors allocation. This way we will end up using vectors less than half of what we are using currently. Vectors allocated are PF_INT + NIX_QINT + NIX_CINT (max queues/cores).
