Di Nitto <fdinitto(a)redhat.com> Date: 2023-09-19 (Tue, 19 Sep 2023) Changed paths: M libknet/threads_rx.c Log Message: ----------- rx: allow links to be active faster scenario: node A and node B node A completes ping/pong link up process faster than B node A starts to send data to node B old behavior: node B would unconditionally discard data packets new behavior: node B will check internal link status to see if ping/pong link up process is in progress. if the link is sending pings and receiving pongs, it´s safe to assume that the link will go up (since we are also receiving data from the node A). node B will speed up link up and accept data immediately. This should address a overall init race condition when nodes startup are slighly off by enough milliseconds to cause 2 memeberships to form and see fencing fireworks. Signed-off-by: Fabio M.
