Hi, all I found this issue when I use ovs 2.6.1 and dpdk 16.07, the error is located in the line "ovs_mutex_lock(&dev->mutex);" in get_stats() in lib/netdev-vport.c, it looks like a deadlock is detected, so resulted in ovs-vswitchd coredump, anybody noticed this issue? How can we fix it? this has bothered me two days.
static int get_stats(const struct netdev *netdev, struct netdev_stats *stats) { struct netdev_vport *dev = netdev_vport_cast(netdev); ovs_mutex_lock(&dev->mutex); /* Passing only collected counters */ stats->tx_packets = dev->stats.tx_packets; stats->tx_bytes = dev->stats.tx_bytes; stats->rx_packets = dev->stats.rx_packets; stats->rx_bytes = dev->stats.rx_bytes; ovs_mutex_unlock(&dev->mutex); return 0; } If I commented out lock and unlock, I'll get the ovs log: ovs_rcu(urcu3)|WARN|blocked 32000 ms waiting for revalidator8 to quiesce ovs-ofctl will also hang. _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
