Pull rdma updates from Jason Gunthorpe: "This has been a smaller cycle than normal. One new driver was accepted, which is unusual, and at least one more driver remains in review on the list. Summary: - Driver fixes for hns, hfi1, nes, rxe, i40iw, mlx5, cxgb4, vmw_pvrdma - Many patches from MatthewW converting radix tree and IDR users to use xarray - Introduction of tracepoints to the MAD layer - Build large SGLs at the start for DMA mapping and get the driver to split them - Generally clean SGL handling code throughout the subsystem - Support for restricting RDMA devices to net namespaces for containers - Progress to remove object allocation boilerplate code from drivers - Change in how the mlx5 driver shows representor ports linked to VFs - mlx5 uapi feature to access the on chip SW ICM memory - Add a new driver for 'EFA'.

This merge commit includes some misc shared code updates from mlx5-next branch needed for net-next. 1) From Aya: Enable general events on all physical link types and restrict general event handling of subtype DELAY_DROP_TIMEOUT in mlx5 rdma driver to ethernet links only as it was intended. 2) From Eli: Introduce low level bits for prio tag mode 3) From Maor: Low level steering updates to support RDMA RX flow steering and enables RoCE loopback traffic when switchdev is enabled. 4) From Vu and Parav: Two small mlx5 core cleanups 5) From Yevgeny add HW definitions of geneve offloads Signed-off-by: Saeed Mahameed

net/mlx5: Eswitch, enable RoCE loopback traffic

2019-04-29T23:55:32Z

When in switchdev mode, we would like to treat loopback RoCE traffic (on eswitch manager) as RDMA and not as regular Ethernet traffic In order to enable it we add flow steering rule that forward RoCE loopback traffic to the HW RoCE filter (by adding allow rule). In addition we add RoCE address in GID index 0, which will be set in the RoCE loopback packet.

net/mlx5: Get rid of storing copy of device name

2019-04-29T23:55:05Z

Currently mlx5 core stores copy of the PCI device name in a mlx5_priv structure and uses pr_warn, pr_err helpers. Get rid of the copy of this name; instead store the parent device pointer that contains name as well as dma specific parameters. This also allows to use kernel's well defined dev_warn, dev_err, dev_dbg device specific print routines. This is also a preparation patch to access non PCI parent device in future.

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: Use get_zeroed_page() for clock_info

2019-04-24T16:40:50Z

get_zeroed_page() returns a virtual address for the page which is better than allocating a struct page and doing a permanent kmap on it. Cc: stable@vger.kernel.org Signed-off-by: Jason Gunthorpe Reviewed-by: Haggai Eran Signed-off-by: Leon Romanovsky Signed-off-by: Jason Gunthorpe

Linux 5.1-rc1 We forgot to reset the branch last merge window thus mlx5-next is outdated and still based on 5.0-rc2. This merge commit is needed to sync mlx5-next branch with 5.1-rc1. Signed-off-by: Saeed Mahameed

This merge commit includes some misc shared code updates from mlx5-next branch needed for net-next. 1) From Maxim, Remove un-used macros and spinlock from mlx5 code. 2) From Aya, Expose Management PCIE info register layout and add rate limit print macros. 3) From Tariq, Compilation warning fix in fs_core.c 4) From Vu, Huy and Saeed, Improve mlx5 initialization flow: The goal is to provide a better logical separation of mlx5 core device initialization flow and will help to seamlessly support creating different mlx5 device types such as PF, VF and SF mlx5 sub-function virtual devices. Mlx5_core driver needs to separate HCA resources from pci resources. Its initialize/load/unload will be broken into stages: 1. Initialize common data structures 2. Setup function which initializes pci resources (for PF/VF) or some other specific resources for virtual device 3. Initialize software objects according to hardware capabilities 4. Load all mlx5_core components It is also necessary to detach mlx5_core mdev name/message from pci device mdev->pdev name/message for a clearer report/debug of different mlx5 device types.
