Allocate and free a security context when creating and destroying a MAD agent. This context is used for controlling access to PKeys and sending and receiving SMPs. When sending or receiving a MAD check that the agent has permission to access the PKey for the Subnet Prefix of the port. During MAD and snoop agent registration for SMI QPs check that the calling process has permission to access the manage the subnet and register a callback with the LSM to be notified of policy changes. When notificaiton of a policy change occurs recheck permission and set a flag indicating sending and receiving SMPs is allowed. When sending and receiving MADs check that the agent has access to the SMI if it's on an SMI QP. Because security policy can change it's possible permission was allowed when creating the agent, but no longer is.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
