I wrongly assumed tp->tcp_mstamp was up to date at the time tcp_rack_reo_timeout() was called. It is not true, since we only update tcp->tcp_mstamp when receiving a packet (as initially done in commit69e996c58a("tcp: add tp->tcp_mstamp field") tcp_rack_reo_timeout() being called by a timer and not an incoming packet, we need to refresh tp->tcp_mstamp Fixes:7c1c730859("tcp: do not pass timestamp to tcp_rack_detect_loss()") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Soheil Hassas Yeganeh <soheil@google.com> Cc: Neal Cardwell <ncardwell@google.com> Cc: Yuchung Cheng <ycheng@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.

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.
