Linux kernel source tree
b2d8754f9a
From Yishai, ----------------------------------- This series enriches DEVX support in few aspects: it enables interoperability between DEVX and verbs and improves mechanism for controlling privileged DEVX commands. The first patch updates mlx5 ifc file. Next 3 patches enable modifying and querying verbs objects via the DEVX interface. To achieve that the core layer introduced the 'UVERBS_IDR_ANY_OBJECT' type to match any IDR object. Once it's used by some driver's method, the infrastructure skips checking for the IDR type and it becomes the driver handler responsibility. The DEVX methods of modify and query were changed to get any object type via the 'UVERBS_IDR_ANY_OBJECT' mechanism. The type checking is done per object as part of the driver code. The next 3 patches introduce more robust mechanism for controlling privileged DEVX commands. The responsibility to block/allow per command was moved to be done in the firmware based on the UID credentials that the driver reports upon user context creation. This enables more granularity per command based on the device security model and the user credentials. In addition, by introducing a valid range for 'general commands' we prevent the need to touch the driver's code any time that a new future command will be added. The last patch fixes the XRC verbs flow once a DEVX context is used. This is needed as XRCD is some shared kernel resource and as such a kernel UID (=0) should be used in its related resources. Thanks Yishai Hadas ----------------------------------- The top 6 patches are the mlx5-devx series, the remainder are from the mlx5-next tree as the mlx5-devx series depended on the mlx5-next mlx5_ifc file update. * mlx5-devx: (42 commits) IB/mlx5: Allow XRC usage via verbs in DEVX context IB/mlx5: Update the supported DEVX commands IB/mlx5: Enforce DEVX privilege by firmware IB/mlx5: Enable modify and query verbs objects via DEVX IB/core: Enable getting an object type from a given uobject IB/core: Introduce UVERBS_IDR_ANY_OBJECT net/mlx5: Update mlx5_ifc with DEVX UCTX capabilities bits RDMA/mlx5: Unfold modify RMP function RDMA/mlx5: Unfold create RMP function RDMA/mlx5: Initialize SRQ tables on mlx5_ib RDMA/mlx5: Update SRQ functions signatures to mlx5_ib format RDMA/mlx5: Use stages for callback to setup and release DEVX RDMA/mlx5: Remove SRQ signature global flag net/mlx5: Move SRQ functions to RDMA part net/mlx5: Remove references to local mlx5_core functions net/mlx5: Remove not-used lib/eq.h header file net/mlx5: Remove dead transobj code net/mlx5: Align SRQ licenses and copyright information net/mlx5: Debug print for forwarded async events net/mlx5: Forward SRQ resource events ...

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
