[ovs-dev] deleting chassis doesn't delete the lport and lflows from northd

Hi team/Ben: Want to get inputs about compute de-comm use case. So when deleting the chassis from southd after gracefully killing the compute, doesn't delete the ports binded to the northd lswitch. Below is the detail of a sandbox from recent scale test env.

[ovs-dev] kernel crash bug caused by ixgbevf kernel module of centos-3.10.0-229.20.1.el7

I found a bug about ixgbevf kernel module in centos-3.10.0-229.20.1.el7. And this bug is also in 3.10.0-514.10.2.el7. How to produce this bug: use SRIOV first, then add lots of network traffic on vf port, and then ifdow/ifup vf port, after many times, this bug happens. BUG: [308026.586026]

Currently, there is one global lock for conntrack module, which protects conntrack entries and conntrack table. All the NAT operations are performed holding this lock. This becomes inefficient, as the number of conntrack entries grow. With new implementation, we will have two PNDIS_RW_LOCK_EX

Hi Pradeep, Yes, this is for sure a bug in the current OVS mempool handling (and possibly in many other DPDK applications). In the past it was perhaps not so critical because shared mempools rarely got released, but with per port mempools it becomes a real threat. And as you say, we do not
