2021-01-29drm/nouveau/dispnv50: Restore pushing of all data.Bastian Beranek2-2/+10
Commit f844eb485eb056ad3b67e49f95cbc6c685a73db4 introduced a regression for NV50, which lead to visual artifacts, tearing and eventual crashes. In the changes of f844eb485eb056ad3b67e49f95cbc6c685a73db4 only the first line was correctly translated to the new NVIDIA header macros: - PUSH_NVSQ(push, NV827C, 0x0110, 0, - 0x0114, 0); + PUSH_MTHD(push, NV827C, SET_PROCESSING, + NVDEF(NV827C, SET_PROCESSING, USE_GAIN_OFS, DISABLE)); The lower part ("0x0114, 0") was probably omitted by accident. This patch restores the push of the missing data and fixes the regression.

2021-01-28io_uring: reinforce cancel on flush during exitPavel Begunkov1-2/+1
What 84965ff8a84f0 ("io_uring: if we see flush on exit, cancel related tasks") really wants is to cancel all relevant REQ_F_INFLIGHT requests reliably. That can be achieved by io_uring_cancel_files(), but we'll miss it calling io_uring_cancel_task_requests(files=NULL) from io_uring_flush(), because it will go through __io_uring_cancel_task_requests(). Just always call io_uring_cancel_files() during cancel, it's good enough for now.

2021-01-28mlxsw: spectrum_span: Do not overwrite policer configurationIdo Schimmel2-0/+7
The purpose of the delayed work in the SPAN module is to potentially update the destination port and various encapsulation parameters of SPAN agents that point to a VLAN device or a GRE tap. The destination port can change following the insertion of a new route, for example. SPAN agents that point to a physical port or the CPU port are static and never change throughout the lifetime of the SPAN agent. Therefore, skip over them in the delayed work. This fixes an issue where the delayed work overwrites the policer that was set on a SPAN agent pointing to the CPU. Modifying the delayed work to inherit the original policer configuration is error-prone, as the same will be needed for any new parameter.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fixes from Thomas Gleixner: "A set of PI futex fixes: - Address a longstanding issue where the user space part of the PI futex is not writeable. The kernel returns with inconsistent state which can in the worst case result in a UAF of a tasks kernel stack. The solution is to establish consistent kernel state which makes future operations on the futex fail because user space and kernel space state are inconsistent. Not a problem as PI futexes fundamentaly require a functional RW mapping and if user space pulls the rug under it, then it can keep the pieces it asked for. - Address an issue where the return value is incorrect in case that the futex was acquired after a timeout/signal made the waiter drop out of the rtmutex wait.

The following case can cause this bug. - mm/slab_common.c: create_cache(): if the __kmem_cache_create() fails, it does: out_free_cache: kmem_cache_free(kmem_cache, s); - but __kmem_cache_create() - at least for slub() - will have done sysfs_slab_add(s) -> sysfs_create_group() .. fails .. -> kobject_del(&s->kobj); .. which frees s ... We can't remove the kmem_cache_free() in create_cache(), because other error cases of __kmem_cache_create() do not free this. So, revert the commit dde3c6b72a16 ("mm/slub: fix a memory leak in sysfs_slab_add()") to fix this.

2021-01-28block: fix bd_size_lock useDamien Le Moal2-4/+7
Some block device drivers, e.g. the skd driver, call set_capacity() with IRQ disabled. This results in lockdep ito complain about inconsistent lock states ("inconsistent {HARDIRQ-ON-W} -> {IN-HARDIRQ-W} usage") because set_capacity takes a block device bd_size_lock using the functions spin_lock() and spin_unlock(). Ensure a consistent locking state by replacing these calls with spin_lock_irqsave() and spin_lock_irqrestore(). The same applies to bdev_set_nr_sectors().

2021-01-28blk-cgroup: Use cond_resched() when destroy blkgsBaolin Wang1-5/+13
On !PREEMPT kernel, we can get below softlockup when doing stress testing with creating and destroying block cgroup repeatly. The reason is it may take a long time to acquire the queue's lock in the loop of blkcg_destroy_blkgs(), or the system can accumulate a huge number of blkgs in pathological cases. We can add a need_resched() check on each loop and release locks and do cond_resched() if true to avoid this issue, since the blkcg_destroy_blkgs() is not called from atomic contexts.

2021-01-28iommu/vt-d: Do not use flush-queue when caching-mode is onNadav Amit1-1/+31
When an Intel IOMMU is virtualized, and a physical device is passed-through to the VM, changes of the virtual IOMMU need to be propagated to the physical IOMMU. The hypervisor therefore needs to monitor PTE mappings in the IOMMU page-tables. Intel specifications provide "caching-mode" capability that a virtual IOMMU uses to report that the IOMMU is virtualized and a TLB flush is needed after mapping to allow the hypervisor to propagate virtual IOMMU mappings to the physical IOMMU. To the best of my knowledge no real physical IOMMU reports "caching-mode" as turned on. Synchronizing the virtual and the physical IOMMU tables is expensive if the hypervisor is unaware which PTEs have changed, as the hypervisor is required to walk all the virtualized tables and look for changes. Consequently, domain flushes are much more expensive than page-specific flushes on virtualized IOMMUs with passthrough devices. The kernel therefore exploited the "caching-mode" indication to avoid domain flushing and use page-specific flushing in virtualized environments. See commit 78d5f0f500e6 ("intel-iommu: Avoid global flushes with caching mode.") This behavior changed after commit 13cf01744608 ("iommu/vt-d: Make use of iova deferred flushing"). Now, when batched TLB flushing is used (the default), full TLB domain flushes are performed frequently, requiring the hypervisor to perform expensive synchronization between the virtual TLB and the physical one. Getting batched TLB flushes to use page-specific invalidations again in such circumstances is not easy, since the TLB invalidation scheme assumes that "full" domain TLB flushes are performed for scalability. Disable batched TLB flushes when caching-mode is on, as the performance benefit from using batched TLB invalidations is likely to be much smaller than the overhead of the virtual-to-physical IOMMU page-tables synchronization.

2021-01-28iommu/amd: Use IVHD EFR for early initialization of IOMMU featuresSuravee Suthikulpanit3-7/+60
IOMMU Extended Feature Register (EFR) is used to communicate the supported features for each IOMMU to the IOMMU driver. This is normally read from the PCI MMIO register offset 0x30, and used by the iommu_feature() helper function. However, there are certain scenarios where the information is needed prior to PCI initialization, and the iommu_feature() function is used prematurely w/o warning. This has caused incorrect initialization of IOMMU. This is the case for the commit 6d39bdee238f ("iommu/amd: Enforce 4k mapping for certain IOMMU data structures") Since, the EFR is also available in the IVHD header, and is available to the driver prior to PCI initialization. Therefore, default to using the IVHD EFR instead.

2021-01-27net: switchdev: don't set port_obj_info->handled true when -EOPNOTSUPPRasmus Villemoes1-10/+13
It's not true that switchdev_port_obj_notify() only inspects the ->handled field of "struct switchdev_notifier_port_obj_info" if call_switchdev_blocking_notifiers() returns 0 - there's a WARN_ON() triggering for a non-zero return combined with ->handled not being true. But the real problem here is that -EOPNOTSUPP is not being properly handled. The wrapper functions switchdev_handle_port_obj_add() et al change a return value of -EOPNOTSUPP to 0, and the treatment of ->handled in switchdev_port_obj_notify() seems to be designed to change that back to -EOPNOTSUPP in case nobody actually acted on the notifier (i.e., everybody returned -EOPNOTSUPP). Currently, as soon as some device down the stack passes the check_cb() check, ->handled gets set to true, which means that switchdev_port_obj_notify() cannot actually ever return -EOPNOTSUPP. This, for example, means that the detection of hardware offload support in the MRP code is broken: switchdev_port_obj_add() used by br_mrp_switchdev_send_ring_test() always returns 0, so since the MRP code thinks the generation of MRP test frames has been offloaded, no such frames are actually put on the wire. Similarly, br_mrp_switchdev_set_ring_role() also always returns 0, causing mrp->ring_role_offloaded to be set to 1. To fix this, continue to set ->handled true if any callback returns success or any error distinct from -EOPNOTSUPP. But if all the callbacks return -EOPNOTSUPP, make sure that ->handled stays false, so the logic in switchdev_port_obj_notify() can propagate that information.
