Branch: refs/heads/master Home: https://github.com/kronosnet/kronosnet Commit: d2a30ac0135c15eebce25a89f943e9062e1b3f6c https://github.com/kronosnet/kronosnet/commit/d2a30ac0135c15eebce25a89f943e… Author: Christine Caulfield <ccaulfie(a)redhat.com> Date: 2020-01-24 (Fri, 24 Jan 2020) Changed paths: M libknet/transport_udp.c Log Message: ----------- [udp] don't make socket spin if a network I/F is down UDP treats ENETUNREACH as a temporary error and just retries, but this causes the TX thread to spin just doing sendto() therefore blocking all other traffic. (To reproduce this try starting corosync with 2 links configured in corosync.conf but only one of them configured to the 'right' address - it will spin in a tight loop and need to be killed with -9) SCTP does not seem to suffer from this.
