Currently, amdgpu_do_flip() spinlocks crtc->dev->event_lock and releases it only after committing updates to the stream. dc_commit_updates_for_stream() should be moved out of spinlock for the below reasons: 1. event_lock is supposed to protect access to acrct->pflip_status _only_ 2. dc_commit_updates_for_stream() has potential sleep's and also its not appropriate to be in an atomic state for such long sequences of code.

2018-06-27dm thin: handle running out of data space vs concurrent discardMike Snitzer
Discards issued to a DM thin device can complete to userspace (via fstrim) _before_ the metadata changes associated with the discards is reflected in the thinp superblock (e.g. free blocks). As such, if a user constructs a test that loops repeatedly over these steps, block allocation can fail due to discards not having completed yet: 1) fill thin device via filesystem file 2) remove file 3) fstrim From initial report, here: https://www.redhat.com/archives/dm-devel/2018-April/msg00022.html "The root cause of this issue is that dm-thin will first remove mapping and increase corresponding blocks' reference count to prevent them from being reused before DISCARD bios get processed by the underlying layers. However. increasing blocks' reference count could also increase the nr_allocated_this_transaction in struct sm_disk which makes smd->old_ll.nr_allocated + smd->nr_allocated_this_transaction bigger than smd->old_ll.nr_blocks. In this case, alloc_data_block() will never commit metadata to reset the begin pointer of struct sm_disk, because sm_disk_get_nr_free() always return an underflow value." While there is room for improvement to the space-map accounting that thinp is making use of: the reality is this test is inherently racey and will result in the previous iteration's fstrim's discard(s) completing vs concurrent block allocation, via dd, in the next iteration of the loop. No amount of space map accounting improvements will be able to allow user's to use a block before a discard of that block has completed. So the best we can really do is allow DM thinp to gracefully handle such aggressive use of all the pool's data by degrading the pool into out-of-data-space (OODS) mode. We _should_ get that behaviour already (if space map accounting didn't falsely cause alloc_data_block() to believe free space was available).. but short of that we handle the current reality that dm_pool_alloc_data_block() can return -ENOSPC.

2018-06-27nfp: reject binding to shared blocksJohn Hurley
TC shared blocks allow multiple qdiscs to be grouped together and filters shared between them. Currently the chains of filters attached to a block are only flushed when the block is removed. If a qdisc is removed from a block but the block still exists, flow del messages are not passed to the callback registered for that qdisc. For the NFP, this presents the possibility of rules still existing in hw when they should be removed. Prevent binding to shared blocks until the kernel can send per qdisc del messages when block unbinds occur. tcf_block_shared() was not used outside of the core until now, so also add an empty implementation for builds with CONFIG_NET_CLS=n.

2018-06-27nfp: flower: fix mpls ether type detectionPieter Jansen van Vuuren
Previously it was not possible to distinguish between mpls ether types and other ether types. This leads to incorrect classification of offloaded filters that match on mpls ether type. For example the following two filters overlap: # tc filter add dev eth0 parent ffff: \ protocol 0x8847 flower \ action mirred egress redirect dev eth1 # tc filter add dev eth0 parent ffff: \ protocol 0x0800 flower \ action mirred egress redirect dev eth2 The driver now correctly includes the mac_mpls layer where HW stores mpls fields, when it detects an mpls ether type. It also sets the MPLS_Q bit to indicate that the filter should match mpls packets.

2018-06-26net/mlx5: Fix command interface race in polling modeAlex Vesker
The command interface can work in two modes: Events and Polling. In the general case, each time we invoke a command, a work is queued to handle it. When working in events, the interrupt handler completes the command execution. On the other hand, when working in polling mode, the work itself completes it. Due to a bug in the work handler, a command could have been completed by the interrupt handler, while the work handler hasn't finished yet, causing the it to complete once again if the command interface mode was changed from Events to polling after the interrupt handler was called. mlx5_unload_one() mlx5_stop_eqs() // Destroy the EQ before cmd EQ ...cmd_work_handler() write_doorbell() --> EVENT_TYPE_CMD mlx5_cmd_comp_handler() // First free free_ent(cmd, ent->idx) complete(&ent->done) <-- mlx5_stop_eqs //cmd was complete // move to polling before destroying the last cmd EQ mlx5_cmd_use_polling() cmd->mode = POLL; --> cmd_work_handler (continues) if (cmd->mode == POLL) mlx5_cmd_comp_handler() // Double free The solution is to store the cmd->mode before writing the doorbell.

2018-06-26PCI: controller: Move PCI_DOMAINS selection to arch KconfigLorenzo Pieralisi
Commit 51bc085d6454 ("PCI: Improve host drivers compile test coverage") added configuration options to allow PCI host controller drivers to be compile tested on all architectures. Some host controller drivers (eg PCIE_ALTERA) config entries select the PCI_DOMAINS config option to enable PCI domains management in the kernel. Now that host controller drivers can be compiled on all architectures, this triggers build regressions on arches that do not implement the PCI_DOMAINS required API (ie pci_domain_nr()): drivers/ata/pata_ali.c: In function 'ali_init_chipset': drivers/ata/pata_ali.c:469:38: error: implicit declaration of function 'pci_domain_nr'; did you mean 'pci_iomap_wc'? Furthemore, some software configurations (ie Jailhouse) require a PCI_DOMAINS enabled kernel to configure multiple host controllers without having an explicit dependency on the ARM platform on which they run. Make PCI_DOMAINS a visible configuration option on ARM so that software configurations that need it can manually select it and move the PCI_DOMAINS selection from PCI controllers configuration file to ARM sub-arch config entries that currently require it, fixing the issue.

In the quest to remove all stack VLA usage from the kernel[1], this allocates the values buffer during the callback instead of putting it on the stack.

2018-06-26net: sched: call reoffload op on block callback regJohn Hurley
Call the reoffload tcf_proto_op on all tcf_proto nodes in all chains of a block when a callback tries to register to a block that already has offloaded rules. If all existing rules cannot be offloaded then the registration is rejected. This replaces the previous policy of rejecting such callback registration outright. On unregistration of a callback, the rules are flushed for that given cb. The implementation of block sharing in the NFP driver, for example, duplicates shared rules to all devs bound to a block. This meant that rules could still exist in hw even after a device is unbound from a block (assuming the block still remains active).

2018-06-26PCI: shpchp: Manage SHPC unconditionally on non-ACPI systemsBjorn Helgaas
An SHPC can be operated either by platform firmware or by the OS. The OS uses a host bridge ACPI _OSC method to negotiate for control of SHPC. If firmware wants to prevent an OS from operating an SHPC, it must supply an _OSC method that declines to grant SHPC ownership to the OS. If acpi_pci_find_root() returns NULL, it means there's no ACPI host bridge device (PNP0A03 or PNP0A08) and hence no _OSC method, so the OS is always allowed to manage the SHPC. Fix a NULL pointer dereference when CONFIG_ACPI=y but the current hardware/firmware platform doesn't support ACPI. In that case, acpi_get_hp_hw_control_from_firmware() is implemented but acpi_pci_find_root() returns NULL.

2018-06-26bpf: fix attach type BPF_LIRC_MODE2 dependency wrt CONFIG_CGROUP_BPFSean Young
If the kernel is compiled with CONFIG_CGROUP_BPF not enabled, it is not possible to attach, detach or query IR BPF programs to /dev/lircN devices, making them impossible to use. For embedded devices, it should be possible to use IR decoding without cgroups or CONFIG_CGROUP_BPF enabled. This change requires some refactoring, since bpf_prog_{attach,detach,query} functions are now always compiled, but their code paths for cgroups need moving out. Rather than a #ifdef CONFIG_CGROUP_BPF in kernel/bpf/syscall.c, moving them to kernel/bpf/cgroup.c and kernel/bpf/sockmap.c does not require #ifdefs since that is already conditionally compiled.
