Add netlink command that enables/disables privileged QKEY by default. It is disabled by default, since according to IB spec only privileged users are allowed to use privileged QKEY. According to the IB specification rel-1.6, section 3.5.3: "QKEYs with the most significant bit set are considered controlled QKEYs, and a HCA does not allow a consumer to arbitrarily specify a controlled QKEY." Using rdma tool, $rdma system set privileged-qkey on When enabled non-privileged users would be able to use controlled QKEYs which are considered privileged. Using rdma tool, $rdma system set privileged-qkey off When disabled only privileged users would be able to use controlled QKEYs. You can also use the command below to check the parameter state: $rdma system show netns shared privileged-qkey off copy-on-fork on Signed-off-by: Patrisious Haddad <phaddad@nvidia.com> Link: https://lore.kernel.org/r/90398be70a9d23d2aa9d0f9fd11d2c264c1be534.1696848201.git.leon@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.
