Currently, SMC enables remote access to physical memory when a user has successfully configured and established an SMC-connection until ten minutes after the last SMC connection is closed. Because this is considered a security risk, drivers are supposed to use IB_PD_UNSAFE_GLOBAL_RKEY in such a case. This patch changes the current SMC code to use IB_PD_UNSAFE_GLOBAL_RKEY. This improves user awareness, but does not remove the security risk itself. Signed-off-by: Ursula Braun <ubraun@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
