When PF responds to the VF requests it also cleans the HW-channel indication in firmware to allow further VF messages to arrive, but the order currently applied is wrong - The PF is copying by DMAE the response the VF is polling on for completion, and only afterwards sets the HW-channel to ready state. This creates a race condition where the VF would be able to send an additional message to the PF before the channel would get ready again, causing the firmware to consider the VF as malicious.

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.
