RACK does not test the loss recovery state correctly to compute the reordering window. It assumes if lost_out is zero then TCP is not in loss recovery. But it can be zero during recovery before calling tcp_rack_detect_loss(): when an ACK acknowledges all packets marked lost before receiving this ACK, but has not yet to discover new ones by tcp_rack_detect_loss(). The fix is to simply test the congestion state directly.

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.
