Check for bad pointer that may result because of kthread_create failure. This check is needed since the gserial setup callback function (gs_console_setup()) is only freeing the info->con_buf in case of kthread_create failure which will result into bad info->console_thread pointer. Without checking info->console_thread pointer validity in the gserial_console_exit() function, before calling kthread_stop(), the rmmod will generate Kernel Oops.

2017-05-16usb: dwc3: gadget: Prevent losing events in event cacheThinh Nguyen
The dwc3 driver can overwite its previous events if its top-half IRQ handler (TH) gets invoked again before processing the events in the cache. We see this as a hang in the file transfer and the host will attempt to reset the device. TH gets the event count and deasserts the interrupt line by writing DWC3_GEVNTSIZ_INTMASK to DWC3_GEVNTSIZ. If there's a new event coming between reading the event count and interrupt deassertion, dwc3 will lose previous pending events. More generally, we will see 0 event count, which should not affect anything. This shouldn't be possible in the current dwc3 implementation. However, through testing and reading the PCIe trace, the TH occasionally still gets invoked one more time after HW interrupt deassertion. (With PCIe legacy interrupts, TH is called repeatedly as long as the interrupt line is asserted). We suspect that there is a small detection delay in the SW. To avoid this issue, Check DWC3_EVENT_PENDING flag to determine if the events are processed in the bottom-half IRQ handler. If not, return IRQ_HANDLED and don't process new event.

Commit 08a36b543803 ("usb: dwc3: gadget: simplify __dwc3_gadget_ep_queue()") caused a small change in the way ISO transfer is handled in the case when XferInProgress event happens on Isoc EP with an active transfer. This caused a performance degradation of 50%. e.g. using g_webcam on DUT and luvcview on host the video frame rate dropped from 16fps to 8fps @high-speed. Make the ISO transfer handling equivalent to that prior to that commit to get back the original ISO performance numbers.

2017-05-16kvm: arm/arm64: Fix use after free of stage2 page tableSuzuki K Poulose
We yield the kvm->mmu_lock occassionaly while performing an operation (e.g, unmap or permission changes) on a large area of stage2 mappings. However this could possibly cause another thread to clear and free up the stage2 page tables while we were waiting for regaining the lock and thus the original thread could end up in accessing memory that was freed. This patch fixes the problem by making sure that the stage2 pagetable is still valid after we regain the lock. The fact that mmu_notifer->release() could be called twice (via __mmu_notifier_release and mmu_notifier_unregsister) enhances the possibility of hitting this race where there are two threads trying to unmap the entire guest shadow pages. While at it, cleanup the redudant checks around cond_resched_lock in stage2_wp_range(), as cond_resched_lock already does the same checks.

The info->target comes from userspace and it would be used directly. So we need to add the sanity check to make sure it is a valid standard target, although the ebtables tool has already checked it. Kernel needs to validate anything coming from userspace. If the target is set as an evil value, it would break the ebtables and cause a panic. Because the non-standard target is treated as one offset. Now add one helper function ebt_invalid_target, and we would replace the macro INVALID_TARGET later.

2017-05-15ldmvsw: unregistering netdev before disable hardwareThomas Tai
When running LDom binding/unbinding test, kernel may panic in ldmvsw_open(). It is more likely that because we're removing the ldc connection before unregistering the netdev in vsw_port_remove(), we set up a window of time where one process could be removing the device while another trying to UP the device. This also sometimes causes vio handshake error due to opening a device without closing it completely. We should unregister the netdev before we disable the "hardware".

2017-05-15dm mpath: multipath_clone_and_map must not return -EIOChristoph Hellwig
Since 412445ac ("dm: introduce a new DM_MAPIO_KILL return value"), the clone_and_map_rq methods must not return errno values, so fix it up to properly return DM_MAPIO_KILL, instead of the -EIO value that snuck in due to a conflict between two patches.

2017-05-15dm mpath: don't return -EIO from dm_report_EIOChristoph Hellwig

2017-05-15ipv6: avoid dad-failures for addresses with NODADMahesh Bandewar
Every address gets added with TENTATIVE flag even for the addresses with IFA_F_NODAD flag and dad-work is scheduled for them. During this DAD process we realize it's an address with NODAD and complete the process without sending any probe. However the TENTATIVE flags stays on the address for sometime enough to cause misinterpretation when we receive a NS. While processing NS, if the address has TENTATIVE flag, we mark it DADFAILED and endup with an address that was originally configured as NODAD with DADFAILED. We can't avoid scheduling dad_work for addresses with NODAD but we can avoid adding TENTATIVE flag to avoid this racy situation.
