When we try to resolve a dest addr, if we don't give src addr, cma core will try to resolve to our source ib device automatically. The current logic only checks if a given port has the same subnet_prefix as our dest, which is not enough if we use default well known subnet_prefix on our active port, as it will be the same as the subnet_prefix on inactive ports and we might match against an inactive port by accident. To resolve this, we should also check if port is active before we resolve it as a suitable src address for a given dest.

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.
