2022-03-01scsi: iscsi: ql4xxx: Use per-session workqueue for unbindingMike Christie
We currently allocate a workqueue per host and only use it for removing the target. For the session per host case we could be using this workqueue to be able to do recoveries (block, unblock, timeout handling) in parallel. To also allow offload drivers to do their session recoveries in parallel, this drops the per host workqueue and replaces it with a per session one.

2022-03-01scsi: core: Remove the cmd field from struct scsi_requestChristoph Hellwig
Now that each scsi_request is backed by a scsi_cmnd, there is no need to indirect the CDB storage. Change all submitters of SCSI passthrough requests to store the CDB information directly in the scsi_cmnd, and while doing so allocate the full 32 bytes that cover all Linux supported SCSI hosts instead of requiring dynamic allocation for > 16 byte CDBs. On 64-bit systems this does not change the size of the scsi_cmnd at all, while on 32-bit systems it slightly increases it for now, but that increase will be made up by the removal of the remaining scsi_request fields.

2022-03-01net/sched: act_ct: Fix flow table lookup failure with no originating ifindexPaul Blakey
After cited commit optimizted hw insertion, flow table entries are populated with ifindex information which was intended to only be used for HW offload. This tuple ifindex is hashed in the flow table key, so it must be filled for lookup to be successful. But tuple ifindex is only relevant for the netfilter flowtables (nft), so it's not filled in act_ct flow table lookup, resulting in lookup failure, and no SW offload and no offload teardown for TCP connection FIN/RST packets. To fix this, add new tc ifindex field to tuple, which will only be used for offloading, not for lookup, as it will not be part of the tuple hash.

git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into arm/drivers Qualcomm driver updates for v5.18 This refactors the Qualcomm mdt file loader, to partially decouple it from the SCM peripheral-authentication-service. This is needed as newer platforms, such as the Qualcomm SM8450, require the metadata to remain accessible to TrustZone during a longer time. This is followed by the introduction of remoteproc drivers for SM8450 (Snapdragon 8 Gen 1). It changes the way hardware version differences are handled in the LLCC driver and introduces support for Qualcomm SM8450. While updating the dt binding for LLCC it also introduces the missing SM8350 compatible. The ocmem and aoss drivers gains missing put_device() calls and rpmpd gains a missing check for kcalloc() failure. The SPM driver is updated to avoid instantiating the SPM cpuidle devices if the CPUs aren't controlled by SPM, such as when Snapdragon 8916 operates in 32-bit mode without PSCI. The RPM power-domain driver gains MSM8226 support. Lastly the socinfo driver gains knowledge about a few new SoCs and PMICs. * tag 'qcom-drivers-for-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux: (37 commits) soc: qcom: rpmpd: Add MSM8226 support dt-bindings: power: rpmpd: Add MSM8226 to rpmpd binding soc: qcom: mdt_loader: Fix split-firmware condition dt-bindings: arm: msm: Add LLCC compatible for SM8450 dt-bindings: arm: msm: Add LLCC compatible for SM8350 soc: qcom: llcc: Add configuration data for SM8450 SoC soc: qcom: llcc: Update register offsets for newer LLCC HW soc: qcom: llcc: Add missing llcc configuration data soc: qcom: llcc: Add write-cache cacheable support soc: qcom: llcc: Update the logic for version info extraction soc: qcom: llcc: Add support for 16 ways of allocation soc: qcom: socinfo: Add some more PMICs and SoCs firmware: qcom: scm: Add support for MC boot address API firmware: qcom: scm: Drop cpumask parameter from set_boot_addr() firmware: qcom: scm: Simplify set_cold/warm_boot_addr() cpuidle: qcom-spm: Check if any CPU is managed by SPM remoteproc: qcom: pas: Add SM8450 remoteproc support dt-bindings: remoteproc: qcom: pas: Add SM8450 PAS compatibles remoteproc: qcom: pas: Carry PAS metadata context soc: qcom: mdt_loader: Extract PAS operations ...

2022-03-01ceph: add getvxattr opMilind Changire
Problem: Some directory vxattrs (e.g. ceph.dir.pin.random) are governed by information that isn't necessarily shared with the client. Add support for the new GETVXATTR operation, which allows the client to query the MDS directly for vxattrs. When the client is queried for a vxattr that doesn't have a special handler, have it issue a GETVXATTR to the MDS directly. Solution: Adds new getvxattr op to fetch ceph.dir.pin*, ceph.dir.layout* and ceph.file.layout* vxattrs. If the entire layout for a dir or a file is being set, then it is expected that the layout be set in standard JSON format. Individual field value retrieval is not wrapped in JSON. The JSON format also applies while setting the vxattr if the entire layout is being set in one go. As a temporary measure, setting a vxattr can also be done in the old format. The old format will be deprecated in the future.

2022-03-01sched/tracing: Report TASK_RTLOCK_WAIT tasks as TASK_UNINTERRUPTIBLEValentin Schneider
TASK_RTLOCK_WAIT currently isn't part of TASK_REPORT, thus a task blocking on an rtlock will appear as having a task state == 0, IOW TASK_RUNNING. The actual state is saved in p->saved_state, but reading it after reading p->__state has a few issues: o that could still be TASK_RUNNING in the case of e.g. rt_spin_lock o ttwu_state_match() might have changed that to TASK_RUNNING As pointed out by Eric, adding TASK_RTLOCK_WAIT to TASK_REPORT implies exposing a new state to userspace tools which way not know what to do with them. The only information that needs to be conveyed here is that a task is waiting on an rt_mutex, which matches TASK_UNINTERRUPTIBLE - there's no need for a new state.

2022-03-01HID: input: remove the need for HID_QUIRK_INVERTBenjamin Tissoires
HID_QUIRK_INVERT is kind of complex to deal with and was bogus. Furthermore, it didn't make sense to use a global per struct hid_device quirk for something dynamic as the current state. Store the current tool information in the report itself, and re-order the processing of the fields to enforce having all the tablet "state" fields before getting to In Range and other input fields. This way, we now have all the information whether a tool is present or not while processing In Range. This new behavior enforces that only one tool gets forwarded to userspace at the same time, and that if either eraser or invert is set, we enforce BTN_TOOL_RUBBER. Note that the release of the previous tool now happens in its own EV_SYN report so userspace doesn't get confused by having 2 tools. These changes are tested in the following hid-tools regression tests: https://gitlab.freedesktop.org/libevdev/hid-tools/-/merge_requests/127 Signed-off-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Reviewed-by: Ping Cheng <ping.cheng@wacom.com> Acked-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2022-03-01KVM: Drop kvm_reload_remote_mmus(), open code request in x86 usersSean Christopherson
Remove the generic kvm_reload_remote_mmus() and open code its functionality into the two x86 callers. x86 is (obviously) the only architecture that uses the hook, and is also the only architecture that uses KVM_REQ_MMU_RELOAD in a way that's consistent with the name. That will change in a future patch, as x86's usage when zapping a single shadow page x86 doesn't actually _need_ to reload all vCPUs' MMUs, only MMUs whose root is being zapped actually need to be reloaded. s390 also uses KVM_REQ_MMU_RELOAD, but for a slightly different purpose. Drop the generic code in anticipation of implementing s390 and x86 arch specific requests, which will allow dropping KVM_REQ_MMU_RELOAD entirely. Opportunistically reword the x86 TDP MMU comment to avoid making references to functions (and requests!) when possible, and to remove the rather ambiguous "this". No functional change intended.

2022-03-01vxlan: vni filtering support on collect metadata deviceRoopa Prabhu
This patch adds vnifiltering support to collect metadata device. Motivation: You can only use a single vxlan collect metadata device for a given vxlan udp port in the system today. The vxlan collect metadata device terminates all received vxlan packets. As shown in the below diagram, there are use-cases where you need to support multiple such vxlan devices in independent bridge domains. Each vxlan device must terminate the vni's it is configured for. Example usecase: In a service provider network a service provider typically supports multiple bridge domains with overlapping vlans. One bridge domain per customer. Vlans in each bridge domain are mapped to globally unique vxlan ranges assigned to each customer. vnifiltering support in collect metadata devices terminates only configured vnis. This is similar to vlan filtering in bridge driver. The vni filtering capability is provided by a new flag on collect metadata device. In the below pic: - customer1 is mapped to br1 bridge domain - customer2 is mapped to br2 bridge domain - customer1 vlan 10-11 is mapped to vni 1001-1002 - customer2 vlan 10-11 is mapped to vni 2001-2002 - br1 and br2 are vlan filtering bridges - vxlan1 and vxlan2 are collect metadata devices with vnifiltering enabled ┌──────────────────────────────────────────────────────────────────┐ │ switch │ │ │ │ ┌───────────┐ ┌───────────┐ │ │ │ │ │ │ │ │ │ br1 │ │ br2 │ │ │ └┬─────────┬┘ └──┬───────┬┘ │ │ vlans│ │ vlans │ │ │ │ 10,11│ │ 10,11│ │ │ │ │ vlanvnimap: │ vlanvnimap: │ │ │ 10-1001,11-1002 │ 10-2001,11-2002 │ │ │ │ │ │ │ │ ┌──────┴┐ ┌──┴─────────┐ ┌───┴────┐ │ │ │ │ swp1 │ │vxlan1 │ │ swp2 │ ┌┴─────────────┐ │ │ │ │ │ vnifilter:│ │ │ │vxlan2 │ │ │ └───┬───┘ │ 1001,1002│ └───┬────┘ │ vnifilter: │ │ │ │ └────────────┘ │ │ 2001,2002 │ │ │ │ │ └──────────────┘ │ │ │ │ │ └───────┼──────────────────────────────────┼───────────────────────┘ │ │ │ │ ┌─────┴───────┐ │ │ customer1 │ ┌─────┴──────┐ │ host/VM │ │customer2 │ └─────────────┘ │ host/VM │ └────────────┘ With this implementation, vxlan dst metadata device can be associated with range of vnis. struct vxlan_vni_node is introduced to represent a configured vni. We start with vni and its associated remote_ip in this structure. This structure can be extended to bring in other per vni attributes if there are usecases for it. A vni inherits an attribute from the base vxlan device if there is no per vni attributes defined. struct vxlan_dev gets a new rhashtable for vnis called vxlan_vni_group. vxlan_vnifilter.c implements the necessary netlink api, notifications and helper functions to process and manage lifecycle of vxlan_vni_node. This patch also adds new helper functions in vxlan_multicast.c to handle per vni remote_ip multicast groups which are part of vxlan_vni_group.

In switchdev where TC rules are offloaded to the FDB this can lead to packets being hit in the FDB where without offload they would have been dropped before reaching TC rules in the kernel. Create a drop rule to make sure packets on inactive ports are dropped before reaching the FDB. Listen on NETDEV_CHANGEUPPER / NETDEV_CHANGEINFODATA events and record the inactive state and offload accordingly. * 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: net/mlx5: Add clarification on sync reset failure net/mlx5: Add reset_state field to MFRL register RDMA/mlx5: Use new command interface API net/mlx5: cmdif, Refactor error handling and reporting of async commands net/mlx5: Use mlx5_cmd_do() in core create_{cq,dct} net/mlx5: cmdif, Add new api for command execution net/mlx5: cmdif, cmd_check refactoring net/mlx5: cmdif, Return value improvements net/mlx5: Lag, offload active-backup drops to hardware net/mlx5: Lag, record inactive state of bond device net/mlx5: Lag, don't use magic numbers for ports net/mlx5: Lag, use local variable already defined to access E-Switch net/mlx5: E-switch, add drop rule support to ingress ACL net/mlx5: E-switch, remove special uplink ingress ACL handling net/mlx5: E-Switch, reserve and use same uplink metadata across ports net/mlx5: Add ability to insert to specific flow group mlx5: remove unused static inlines ==================== Link: https://lore.kernel.org/r/20220223233930.319301-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
