[ Upstream commit d6acfeb1 ] vxlan dev currently ignores lowerdev's gso_max_size, which adversely affects TSO performance of liquidio if it's the lowerdev. Egress TCP packets' skb->len often exceed liquidio's advertised gso_max_size. This may happen on other NIC drivers. Fix it by assigning lowerdev's gso_max_size to that of vxlan dev. Might as well do likewise for gso_max_segs. Single flow TSO throughput of liquidio as lowerdev (using iperf3): Before the patch: 139 Mbps After the patch : 8.68 Gbps Percent increase: 6,144 % Signed-off-by:

[ Upstream commit 2ed2b862 ] commit bbeddf52 ("printk: move braille console support into separate braille.[ch] files") introduced _braille_console_setup() to outline the braille initialization code. There was however some confusion over the value it was supposed to return. commit 2cfe6c4a ("printk: Fix return of braille_register_console()") tried to fix it but failed to. This fixes and documents the returned value according to the use in printk.c: non-zero return means a parsing error, and thus this console configuration should be ignored. Signed-off-by:

[ Upstream commit 142c6594 ] Some device drivers reset their stats at down/up events, possibly fooling bonding stats, since they operate with relative deltas. It is nearly not possible to fix drivers, since some of them compute the tx/rx counters based on per rx/tx queue stats, and the queues can be reconfigured (ethtool -L) between the down/up sequence. Lets avoid accumulating 'negative' values that render bonding stats useless. It is better to lose small deltas, assuming the bonding stats are fetched at a reasonable frequency.

[ Upstream commit 06cceedc ] cgroup could be throttled to a limit but when all cgroups cross high limit, queue enters a higher state and so the group should be throttled to a higher limit. It's possible the cgroup is sleeping because of throttle and other cgroups don't dispatch IO any more. In this case, nobody can trigger current downgrade/upgrade logic. To fix this issue, we could either set up a timer to wakeup the cgroup if other cgroups are idle or make sure this cgroup doesn't sleep too long. Setting up a timer means we must change the timer very frequently. This patch chooses the latter. Making cgroup sleep time not too big wouldn't change cgroup bps/iops, but could make it wakeup more frequently, which isn't a big issue because throtl_slice * 8 is already quite big. Signed-off-by:

[ Upstream commit 7f3ff14b ] sdma_disable_channel() cannot ensure dma is stopped to access module's FIFOs. There is chance SDMA core is running and accessing BD when disable of corresponding channel, this may cause sometimes even after call of .sdma_disable_channel(), SDMA core still be running and accessing module's FIFOs. According to NXP R&D team a delay of one BD SDMA cost time (maximum is 1ms) should be added after disable of the channel bit, to ensure SDMA core has really been stopped after SDMA clients call .device_terminate_all. This patch introduces adds a new function sdma_disable_channel_with_delay() which simply adds 1ms delay after call sdma_disable_channel(), and set it as .device_terminate_all. Signed-off-by:

[ Upstream commit c4836742 ] Because sysctl_tcp_adv_win_scale could be changed any time, so there is one race in tcp_win_from_space. For example, 1.sysctl_tcp_adv_win_scale<=0 (sysctl_tcp_adv_win_scale is negative now) 2.space>>(-sysctl_tcp_adv_win_scale) (sysctl_tcp_adv_win_scale is postive now) As a result, tcp_win_from_space returns 0. It is unexpected. Certainly if the compiler put the sysctl_tcp_adv_win_scale into one register firstly, then use the register directly, it would be ok. But we could not depend on the compiler behavior. Signed-off-by:

[ Upstream commit cf5cd9d4 ] The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:<device>. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. The compatible strings don't have a vendor prefix because that's how it's used currently, and changing this will be a Device Tree ABI break. Signed-off-by:

[ Upstream commit 01070427 ] On systems with a large number of CPUs, running sysrq-<q> can cause watchdog timeouts. There are two slow sections of code in the sysrq-<q> path in timer_list.c. 1. print_active_timers() - This function is called by print_cpu() and contains a slow goto loop. On a machine with hundreds of CPUs, this loop took approximately 100ms for the first CPU in a NUMA node. (Subsequent CPUs in the same node ran much quicker.) The total time to print all of the CPUs is ultimately long enough to trigger the soft lockup watchdog. 2. print_tickdevice() - This function outputs a large amount of textual information. This function also took approximately 100ms per CPU. Since sysrq-<q> is not a performance critical path, there should be no harm in touching the nmi watchdog in both slow sections above. Touching it in just one location was insufficient on systems with hundreds of CPUs as occasional timeouts were still observed during testing. This issue was observed on an Oracle T7 machine with 128 CPUs, but I anticipate it may affect other systems with similarly large numbers of CPUs. Signed-off-by:

[ Upstream commit 1b8955bc ] The scheduler clock framework may not use the correct timeout for the clock wrap. This happens when a new clock driver calls sched_clock_register() after the kernel called sched_clock_postinit(). In this case the clock wrap timeout is too long thus sched_clock_poll() is called too late and the clock already wrapped. On my ARM system the scheduler was no longer scheduling any other task than the idle task because the sched_clock() wrapped. Signed-off-by:

[ Upstream commit a3a5129e ] Consider the following situation which has been found in a test setup: Gateway B has claimed client C and gateway A has the same backbone network as B. C sends a broad- or multicast to B and directly after this packet decides to send another packet to A due to a better TQ value. B will forward the broad-/multicast into the backbone as it is the responsible gw and after that A will claim C as it has been chosen by C as the best gateway. If it now happens that A claims C before it has received the broad-/multicast forwarded by B (due to backbone topology or due to some delay in B when forwarding the packet) we get a critical situation: in the current code A will immediately unclaim C when receiving the multicast due to the roaming client scenario although the position of C has not changed in the mesh. If this happens the multi-/broadcast forwarded by B will be sent back into the mesh by A and we have looping packets until one of the gateways claims C again. In order to prevent this, unclaiming of a client due to the roaming client scenario is only done after a certain time is expired after the last claim of the client. 100 ms are used here, which should be slow enough for big backbones and slow gateways but fast enough not to break the roaming client use case.

[ Upstream commit 88997e42 ] wanted_features is a set of features which have to be enabled if a hardware allows that. Currently when a vlan device is created, its wanted_features is set to current features of its base device. The problem is that the base device can get new features and they are not propagated to vlan-s of this device. If we look at bonding devices, they doesn't have this problem and this patch suggests to fix this issue by the same way how it works for bonding devices. We meet this problem, when we try to create a vlan device over a bonding device. When a system are booting, real devices require time to be initialized, so bonding devices created without slaves, then vlan devices are created and only then ethernet devices are added to the bonding device.

[ Upstream commit c3883fe0 ] This patch fixes an issue in drivers/hid/hid-input.c where values outside of the logical range are not clamped when "null state" bit of the input control is not set. This was discussed on the lists [1] and this change stems from the fact due to the ambiguity of the HID specification it might be appropriate to follow Microsoft's own interpretation of the specification. As noted in Microsoft's documentation [2] in the section titled "Required HID usages for digitizers" it is noted that values reported outside the logical range "will be considered as invalid data and the value will be changed to the nearest boundary value (logical min/max)." This patch fixes an issue where the (1292:4745) Innomedia INNEX GENESIS/ATARI reports out of range values for its X and Y axis of the DPad which, due to the null state bit being unset, are forwarded to userspace as is. Now these values will get clamped to the logical range before being forwarded to userspace. This device was also used to test this patch. This patch expands on commit 3f375270 ("HID: reject input outside logical range only if null state is set").

Error: Failed to delete events. 255 But now perf_del_probe_events() will always set ret = 0, different from previous del_perf_probe_events(). After this, it returns errno again, eg, -bash-4.3# ./perf probe -d xxx || echo $? "xxx" does not hit any event.

[ Upstream commit 608b2050 ] On vblank instant-off systems, we can get into a situation where the cost of enabling and disabling the vblank IRQ around a drmWaitVblank query dominates. And with the advent of even deeper hardware sleep state, touching registers becomes ever more expensive. However, we know that if the user wants the current vblank counter, they are also very likely to immediately queue a vblank wait and so we can keep the interrupt around and only turn it off if we have no further vblank requests queued within the interrupt interval. After vblank event delivery, this patch adds a shadow of one vblank where the interrupt is kept alive for the user to query and queue another vblank event. Similarly, if the user is using blocking drmWaitVblanks, the interrupt will be disabled on the IRQ following the wait completion. However, if the user is simply querying the current vblank counter and timestamp, the interrupt will be disabled after every IRQ and the user will enabled it again on the first query following the IRQ. v2: Mario Kleiner - After testing this, one more thing that would make sense is to move the disable block at the end of drm_handle_vblank() instead of at the top. Turns out that if high precision timestaming is disabled or doesn't work for some reason (as can be simulated by echo 0 > /sys/module/drm/parameters/timestamp_precision_usec), then with your delayed disable code at its current place, the vblank counter won't increment anymore at all for instant queries, ie. with your other "instant query" patches. Clients which repeatedly query the counter and wait for it to progress will simply hang, spinning in an endless query loop. There's that comment in vblank_disable_and_save: "* Skip this step if there isn't any high precision timestamp * available. In that case we can't account for this and just * hope for the best. */ With the disable happening after leading edge of vblank (== hw counter increment already happened) but before the vblank counter/timestamp handling in drm_handle_vblank, that step is needed to keep the counter progressing, so skipping it is bad. Now without high precision timestamping support, a kms driver must not set dev->vblank_disable_immediate = true, as this would cause problems for clients, so this shouldn't matter, but it would be good to still make this robust against a future kms driver which might have unreliable high precision timestamping, e.g., high precision timestamping that intermittently doesn't work. v3: Patch before coffee needs extra coffee.

[ Upstream commit 88b897a3 ] This patch significantly improves the execution time of perf_event__synthesize_mmap_events() when running perf record on systems where processes have lots of threads. It just happens that cat /proc/pid/maps support uses a O(N^2) algorithm to generate each map line in the maps file. If you have 1000 threads, then you have necessarily 1000 stacks. For each vma, you need to check if it corresponds to a thread's stack. With a large number of threads, this can take a very long time. I have seen latencies >> 10mn. As of today, perf does not use the fact that a mapping is a stack, therefore we can work around the issue by using /proc/pid/tasks/pid/maps. This entry does not try to map a vma to stack and is thus much faster with no loss of functonality. The proc-map-timeout logic is kept in case users still want some upper limit. In V2, we fix the file path from /proc/pid/tasks/pid/maps to actual /proc/pid/task/pid/maps, tasks -> task. Thanks Arnaldo for catching this.

[ Upstream commit fda78d7a ] The pci_bus_type .shutdown method, pci_device_shutdown(), is called from device_shutdown() in the kernel restart and shutdown paths. Previously, pci_device_shutdown() called pci_msi_shutdown() and pci_msix_shutdown(). This disables MSI and MSI-X, which causes the device to fall back to raising interrupts via INTx. But the driver is still bound to the device, it doesn't know about this change, and it likely doesn't have an INTx handler, so these INTx interrupts cause "nobody cared" warnings like this: irq 16: nobody cared (try booting with the "irqpoll" option) CPU: 0 PID: 0 Comm: swapper/0 Not tainted 4.8.2-1.el7_UNSUPPORTED.x86_64 #1 Hardware name: Hewlett-Packard HP Z820 Workstation/158B, BIOS J63 v03.90 06/ ... The MSI disabling code was added by d52877c7 ("pci/irq: let pci_device_shutdown to call pci_msi_shutdown v2") because a driver left MSI enabled and kdump failed because the kexeced kernel wasn't prepared to receive the MSI interrupts. Subsequent commits 1851617c ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI") and e80e7edc ("PCI/MSI: Initialize MSI capability for all architectures") changed the kexeced kernel to disable all MSIs itself so it no longer depends on the crashed kernel to clean up after itself. Stop disabling MSI/MSI-X in pci_device_shutdown(). This resolves the "nobody cared" unhandled IRQ issue above. It also allows PCI serial devices, which may rely on the MSI interrupts, to continue outputting messages during reboot/shutdown.

[ Upstream commit 86107838 ] If fbdev emulation is disabled, the QXL shutdown path will try to clean a framebuffer that wasn't initialized, hitting the Oops below. The problem is that even when FBDEV_EMULATION is disabled we allocate the qfbdev strutucture, but we don't initialize it. The fix is to stop allocating the memory, since it won't be used. This allows the existing verification in the cleanup hook to do it's job preventing the oops. Now that we don't allocate the unused fbdev structure, we need to be careful when dereferencing it in the PM suspend hook.
