Hi Neutrinos,

time for a new cycle of bug deputy rotation, which means I was on duty last week, checking bugs up to 1835663 included

Quite a few bugs in that list worth a read and further discussion:
* port status changing to UP when changing the network name (and possible fallout on DHCP issues)
* API currently allowing to set gateway outside of the subnet
* How to handle external dependencies recommended version bumps (pyroute bump in queens fixing a memory leak)
* possible issue in IPv6 address renewal since we started cleaning the dnsmasq leases file

Critical:
* Wrong endpoints config with configure_auth_token_middleware - https://bugs.launchpad.net/bugs/1834849
  Removal of devstack deprecated option broke designate scenario job
  Fix merged: https://review.opendev.org/668447

High:
* [Queens] Memory leak in pyroute2 0.4.21 - https://bugs.launchpad.net/neutron/+bug/1835044
  we need a newer pyroute version
  Patches on requirements with DNM neutron one for testing in progress: https://review.opendev.org/668676 and https://review.opendev.org/668677
  openstack-discuss thread: http://lists.openstack.org/pipermail/openstack-discuss/2019-July/007545.html
* Bulk-created ports ignore binding_host_id property - https://bugs.launchpad.net/neutron/+bug/1835209
  Issue on bulk port creation work
  Fix in progress: https://review.opendev.org/#/c/665516/
* flood flow in br-tun table22 incorrect - https://bugs.launchpad.net/neutron/+bug/1835163
  Linked to https://bugs.launchpad.net/neutron/+bug/1834979 (see below), this can cause hard to trace l2pop and dhcp issues
  No owner

Medium:
* Add ipam.utils.check_gateway_invalid_in_subnet unit tests - https://bugs.launchpad.net/neutron/+bug/1835448
  Shows proper usage after bug https://bugs.launchpad.net/neutron/+bug/1835344 (see in Opinion section)
  Review in progress: https://review.opendev.org/669210
* Port status becomes active after updating network/subnet - https://bugs.launchpad.net/neutron/+bug/1834979
  The port of a turned off VM will show as UP after a network modification (reproducer with network name)
  No owner
* Some L3 RPCs are time-consuming especially get_routers - https://bugs.launchpad.net/neutron/+bug/1835663
  Probably worth discussing in performance meeting?
  
Incomplete:
* Restart dhcp-agent cause IPv6 vm can't renew IP address, will lost minutes or hours - https://bugs.launchpad.net/neutron/+bug/1835484
  Cleaning IPv6 addresses from dnsmasq leases file (https://bugs.launchpad.net/neutron/+bug/1722126) apparently causes VM to loose its address on renewal
  Waiting for detailed logs, but if ipv6 experts can chime in

Opinion:
* neutron doesn't check the validity of gateway_ip as a subnet had been created - https://bugs.launchpad.net/neutron/+bug/1835344
  How to handle gateway IP outside of the subnet?
  Discussion in the bug and related review: https://review.opendev.org/669030

Duplicate:
* QoS plugin slows down get_ports operation - https://bugs.launchpad.net/neutron/+bug/1835369
  Was filled close to https://bugs.launchpad.net/bugs/1834484
