RDMA/core: Change system parameters callback from dumpit to doit

2019-05-14T01:16:48Z

.dumpit() callback is used for returning same type of data in the loop, e.g. loop over ports, resources, devices. However system parameters are general and standalone for whole subsystem. It means that getting system parameters should be doit callback.

RDMA: Add EFA related definitions

2019-05-06T16:47:50Z

Add EFA driver ID to the IOCTL interface uapi. This patch also adds unspecified node/transport type that will be used by EFA (usnic is left unchanged as it's already part of our ABI).

IB/mlx5: Add steering SW ICM device memory type

2019-05-06T15:51:51Z

This patch adds support for allocating, deallocating and registering a new device memory type, STEERING_SW_ICM. This memory can be allocated and used by a privileged user for direct rule insertion and management of the device's steering tables. The type is provided by the user via the dedicated attribute in the alloc_dm ioctl command.

IB/mlx5: Support device memory type attribute

2019-05-06T15:51:50Z

This patch intoruduces a new mlx5_ib driver attribute to the DM allocation method - the DM type. In order to allow addition of new types in downstream patches this patch also refactors the allocation, deallocation and registration handlers to consider the requested type and perform the necessary actions according to it. Since not all future device memory types will be such that are mapped to user memory, the mandatory page index output attribute is modified to be optional.

IB/mlx5: Expose TIR ICM address to user space

2019-04-25T13:03:19Z

This patch exposes the TIR ICM address of raw packet and RSS QPs to user space. In order to pass the new field, the patch extends the mlx5 specific QP creation response structure and fills it with the icm address returned by the FW command, if available.

Merge branch 'rdma_mmap' into rdma.git for-next

2019-04-24T19:20:34Z

Jason Gunthorpe says: ==================== Upon review it turns out there are some long standing problems in BAR mapping area: * BAR pages intended for read-only can be switched to writable via mprotect. * Missing use of rdma_user_mmap_io for the mlx5 clock BAR page. * Disassociate causes SIGBUS when touching the pages. * CPU pages are being mapped through to the process via remap_pfn_range instead of the more appropriate vm_insert_page, causing weird behaviors during disassociation. This series adds the missing VM_* flag manipulation, adds faulting a zero page for disassociation and revises the CPU page mappings to use vm_insert_page. ==================== For dependencies this branch is based on for-rc from git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma.git * branch 'rdma_mmap': RDMA: Remove rdma_user_mmap_page RDMA/mlx5: Use get_zeroed_page() for clock_info RDMA/ucontext: Fix regression with disassociate RDMA/mlx5: Use rdma_user_map_io for mapping BAR pages RDMA/mlx5: Do not allow the user to write to the clock page Signed-off-by: Jason Gunthorpe

RDMA/mlx5: Allow inserting a steering rule to the FDB

2019-04-22T18:24:05Z

Allow this only via mlx5 raw create flow API, legacy verbs are not supported. To accommodate that, we add a new attribute to matcher creation to indicate the type of flow table to be used. MLX5_IB_ATTR_FLOW_MATCHER_FT_TYPE With this new attribute MLX5_IB_ATTR_FLOW_MATCHER_FLOW_FLAGS is no longer needed, we keep it for compatibility but at most only a single attribute can be passed of the two. When inserting a flow rule to the FDB we require that a DEVX FT is provided as a destination, no other configuration is allowed.

RDMA/core: Add a netlink command to change net namespace of rdma device

2019-04-22T17:44:58Z

Provide an option to change the net namespace of a rdma device through a netlink command. When multiple rdma devices exists in a system, and when containers are used, this will limit rdma device visibility to a specified net namespace. An example command to change net namespace of mlx5_1 device to the previously created net namespace 'foo' is: $ ip netns add foo $ rdma dev set mlx5_1 netns foo Signed-off-by: Parav Pandit Signed-off-by: Jason Gunthorpe
