git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "This is a big pull request. Of note is that I'm sending you the new ioctl API for the rdma subsystem. We put it up on linux-api@, but didn't get much response. The API is complex, but it solves two different problems in one go: 1) The bi-directional nature of the RDMA file write calls, which created the security hole we had to handle (and for which the fix is now causing problems for systems in production, we were a bit over zealous in the fix and the ability to open a device, then fork, then create new queue pairs on the device and use them is broken). 2) The bloat caused by different vendors implementing extensions to the base verbs API. Each vendor's hardware is slightly different, and the hardware might be suitable for one extension but not another. By the time we add generic extensions for all the different ways that the different hardware can offload things, the API becomes bloated. Things like our completion structs have started to exceed a cache line in size because of all the elements needed to support this. That in turn shows up heavily in the performance graphs with a noticable drop in performance on 100Gigabit links as our completion structs go from occupying one cache line to 1+. This API makes things like the completion structs modular in a very similar way to netlink so that your structs can only include the items needed for the offloads/features you are actually using on a given queue pair. In that way we support everything, but only use what we need, and our structs stay smaller. The ioctl API is better explained by the posting on linux-api@ than I can explain it here, so I'll just leave it at that. The rest of the pull request is typical stuff.

2017-09-01mlxsw: spectrum: Forbid linking to devices that have uppersIdo Schimmel1-0/+6
The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.

2017-08-31Input: xpad - fix PowerA init quirk for some gamepad modelsCameron Gutman1-5/+19
The PowerA gamepad initialization quirk worked with the PowerA wired gamepad I had around (0x24c6:0x543a), but a user reported [0] that it didn't work for him, even though our gamepads shared the same vendor and product IDs. When I initially implemented the PowerA quirk, I wanted to avoid actually triggering the rumble action during init. My tests showed that my gamepad would work correctly even if it received a rumble of 0 intensity, so that's what I went with. Unfortunately, this apparently isn't true for all models (perhaps a firmware difference?). This non-working gamepad seems to require the real magic rumble packet that the Microsoft driver sends, which actually vibrates the gamepad. To counteract this effect, I still send the old zero-rumble PowerA quirk packet which cancels the rumble effect before the motors can spin up enough to vibrate.

2017-08-31IB/core: Add completion queue (cq) object actionsMatan Barak1-1/+137
Adding CQ ioctl actions: 1. create_cq 2. destroy_cq This requires adding the following: 1. A specification describing the method a. Handler b. Attributes specification Each attribute is one of the following: a. PTR_IN - input data Note: This could be encoded inlined for data < 64bit b. PTR_OUT - response data c. IDR - idr based object d. FD - fd based object Blobs attributes (clauses a and b) contain their type, while objects specifications (clauses c and d) contains the expected object type (for example, the given id should be UVERBS_TYPE_PD) and the required access (READ, WRITE, NEW or DESTROY). If a NEW is required, the new object's id will be assigned to this attribute. All attributes could get UA_FLAGS attribute. Currently we support stating that an attribute is mandatory or that the specification size corresponds to a lower bound (and that this attribute could be extended). We currently add both default attributes and the two generic UHW_IN and UHW_OUT driver specific attributes. 2. Handler A handler gets a uverbs_attr_bundle. The handler developer uses uverbs_attr_get to fetch an attribute of a given id. Each of these attribute groups correspond to the specification group defined in the action (clauses 1.b and 1.c respectively). The indices of these arrays corresponds to the attribute ids declared in the specifications (clause 2). The handler is quite simple. It assumes the infrastructure fetched all objects and locked, created or destroyed them as required by the specification. Pointer (or blob) attributes were validated to match their required sizes. After the handler finished, the infrastructure commits or rollbacks the objects.

In this phase, we don't want to change all the drivers to use flexible driver's specific attributes. Therefore, we add two default attributes: UHW_IN and UHW_OUT. These attributes are optional in some methods and they encode the driver specific command data. We add a function that extract this data and creates the legacy udata over it. Driver's data should start from UVERBS_UDATA_DRIVER_DATA_FLAG. This turns on the first bit of the namespace, indicating this attribute belongs to the driver's namespace.

2017-08-31IB/core: Explicitly destroy an object while keeping uobjectMatan Barak1-0/+35
When some objects are destroyed, we need to extract their status at destruction. After object's destruction, this status (e.g. events_reported) relies in the uobject. In order to have the latest and correct status, the underlying object should be destroyed, but we should keep the uobject alive and read this information off the uobject. We introduce a rdma_explicit_destroy function. This function destroys the class type object (for example, the IDR class type which destroys the underlying object as well) and then convert the uobject to be of a null class type. This uobject will then be destroyed as any other uobject once uverbs_finalize_object[s] is called.

2017-08-31IB/core: Add uverbs merge trees functionalityMatan Barak2-1/+667
Different drivers support different features and even subset of the common uverbs implementation. Currently, this is handled as bitmask in every driver that represents which kind of methods it supports, but doesn't go down to attributes granularity. Moreover, drivers might want to add their specific types, methods and attributes to let their user-space counter-parts be exposed to some more efficient abstractions. It means that existence of different features is validated syntactically via the parsing infrastructure rather than using a complex in-handler logic. In order to do that, we allow defining features and abstractions as parsing trees. These per-feature parsing tree could be merged to an efficient (perfect-hash based) parsing tree, which is later used by the parsing infrastructure. To sum it up, this makes a parse tree unique for a device and represents only the features this particular device supports. This is done by having a root specification tree per feature. Before a device registers itself as an IB device, it merges all these trees into one parsing tree. This parsing tree is used to parse all user-space commands. A future user-space application could read this parse tree. This tree represents which objects, methods and attributes are supported by this device.

Moreover, it supports executing methods which are related to the device itself, such as QUERY_DEVICE. This is a singleton object (per file instance).

2017-08-31IB/core: Add new ioctl interfaceMatan Barak4-1/+416
In this ioctl interface, processing the command starts from properties of the command and fetching the appropriate user objects before calling the handler. Parsing and validation is done according to a specifier declared by the driver's code. In the driver, all supported objects are declared. These objects are separated to different object namepsaces. Dividing objects to namespaces is done at initialization by using the higher bits of the object ids. This initialization can mix objects declared in different places to one parsing tree using in this ioctl interface. For each object we list all supported methods. Similarly to objects, methods are separated to method namespaces too. Namespacing is done similarly to the objects case. This could be used in order to add methods to an existing object. Each method has a specific handler, which could be either a default handler or a driver specific handler. Along with the handler, a bunch of attributes are specified as well. Similarly to objects and method, attributes are namespaced and hashed by their ids at initialization too. All supported attributes are subject to automatic fetching and validation. These attributes include the command, response and the method's related objects' ids. When these entities (objects, methods and attributes) are used, the high bits of the entities ids are used in order to calculate the hash bucket index. Then, these high bits are masked out in order to have a zero based index. Since we use these high bits for both bucketing and namespacing, we get a compact representation and O(1) array access. This is mandatory for efficient dispatching. Each attribute has a type (PTR_IN, PTR_OUT, IDR and FD) and a length. Attributes could be validated through some attributes, like: (*) Minimum size / Exact size (*) Fops for FD (*) Object type for IDR If an IDR/fd attribute is specified, the kernel also states the object type and the required access (NEW, WRITE, READ or DESTROY). All uobject/fd management is done automatically by the infrastructure, meaning - the infrastructure will fail concurrent commands that at least one of them requires concurrent access (WRITE/DESTROY), synchronize actions with device removals (dissociate context events) and take care of reference counting (increase/decrease) for concurrent actions invocation. The reference counts on the actual kernel objects shall be handled by the handlers. objects +--------+ | | | | methods +--------+ | | ns method method_spec +-----+ |len | +--------+ +------+[d]+-------+ +----------------+[d]+------------+ |attr1+-> |type | | object +> |method+-> | spec +-> + attr_buckets +-> |default_chain+--> +-----+ |idr_type| +--------+ +------+ |handler| | | +------------+ |attr2| |access | | | | | +-------+ +----------------+ |driver chain| +-----+ +--------+ | | | | +------------+ | | +------+ | | | | | | | | | | | | | | | | | | | | +--------+ [d] = Hash ids to groups using the high order bits The right types table is also chosen by using the high bits from the ids. Currently we have either default or driver specific groups. Once validation and object fetching (or creation) completed, we call the handler: int (*handler)(struct ib_device *ib_dev, struct ib_uverbs_file *ufile, struct uverbs_attr_bundle *ctx); ctx bundles attributes of different namespaces. Each element there is an array of attributes which corresponds to one namespaces of attributes. For example, in the usually used case: ctx core +----------------------------+ +------------+ | core: +---> | valid | +----------------------------+ | cmd_attr | | driver: | +------------+ |----------------------------+--+ | valid | | | cmd_attr | | +------------+ | | valid | | | obj_attr | | +------------+ | | drivers | +------------+ +> | valid | | cmd_attr | +------------+ | valid | | cmd_attr | +------------+ | valid | | obj_attr | +------------+ Signed-off-by: Matan Barak <matanb@mellanox.com> Reviewed-by: Yishai Hadas <yishaih@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

2017-08-30net/mlx5e: Fix CQ moderation mode not set properlyTal Gilboa1-0/+1
cq_period_mode assignment was mistakenly removed so it was always set to "0", which is EQE based moderation, regardless of the device CAPs and requested value in ethtool.

2017-08-30net/mlx5: E-Switch, Unload the representors in the correct orderShahar Klein1-1/+1
When changing from switchdev to legacy mode, all the representor port devices (uplink nic and reps) are cleaned up. Part of this cleaning process is removing the neigh entries and the hash table containing them. However, a representor neigh entry might be linked to the uplink port hash table and if the uplink nic is cleaned first the cleaning of the representor will end up in null deref. Fix that by unloading the representors in the opposite order of load.

2017-08-30net/mlx5e: Properly resolve TC offloaded ipv6 vxlan tunnel source addressPaul Blakey1-5/+3
Currently if vxlan tunnel ipv6 src isn't supplied the driver fails to resolve it as part of the route lookup. The resulting encap header is left with a zeroed out ipv6 src address so the packets are sent with this src ip. Use an appropriate route lookup API that also resolves the source ipv6 address if it's not supplied.

2017-08-30net/mlx5e: Don't override user RSS upon set channelsInbar Karmy1-2/+4
Currently, increasing the number of combined channels is changing the RSS spread to use the new created channels. Prevent the RSS spread change in case the user explicitly declare it, to avoid overriding user configuration. Tested: when RSS default: # ethtool -L ens8 combined 4 RSS spread will change and point to 4 channels. # ethtool -X ens8 equal 4 # ethtool -L ens8 combined 6 RSS will not change after increasing the number of the channels.
