[kronosnet/kronosnet] 268f9f: UDP: Don't keep retrying send if we get EINVAL

Branch: refs/heads/stable1-proposed Home: https://github.com/kronosnet/kronosnet Commit: 268f9ff9b0ff88291ac3582a334a864edcbdaf02 https://github.com/kronosnet/kronosnet/commit/268f9ff9b0ff88291ac3582a334a8… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2018-02-20 (Tue, 20 Feb 2018) Changed paths: M libknet/transport_udp.c Log Message: ----------- UDP: Don't keep retrying send if we get EINVAL UDP can return EINVAL if the route is down or not configured, this can cause knet to 'spin' (well, ish, there is a usleep in there). With this patch in place knet doesn't hog the CPU anywhere near so much (and it does recover if the link returns). Signed-off-by: Christine Caulfield <ccaulfie(a)redhat.com>
