Mark Bloch Says: ================ Expose steering anchor Expose a steering anchor per priority to allow users to re-inject packets back into default NIC pipeline for additional processing. MLX5_IB_METHOD_STEERING_ANCHOR_CREATE returns a flow table ID which a user can use to re-inject packets at a specific priority. A FTE (flow table entry) can be created and the flow table ID used as a destination. When a packet is taken into a RDMA-controlled steering domain (like software steering) there may be a need to insert the packet back into the default NIC pipeline. This exposes a flow table ID to the user that can be used as a destination in a flow table entry. With this new method priorities that are exposed to users via MLX5_IB_METHOD_FLOW_MATCHER_CREATE can be reached from a non-zero UID. As user-created flow tables (via RDMA DEVX) are created with a non-zero UID thus it's impossible to point to a NIC core flow table (core driver flow tables are created with UID value of zero) from userspace. Create flow tables that are exposed to users with the shared UID, this allows users to point to default NIC flow tables. Steering loops are prevented at FW level as FW enforces that no flow table at level X can point to a table at level lower than X. ================ Link: https://lore.kernel.org/all/20220703205407.110890-1-saeed@kernel.org Signed-off-by: Leon Romanovsky <leon@kernel.org> |

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.
