            Can't install Devstack for ML2 Mechanism Driver Development
            Asked 2021-Dec-22 at 08:24

            I want to develop a Neutron ML2 mechanism driver. The reason is because I want that my own implementation of a software L2 Switch and my own Network Management Agent is able to interact with OpenStack. I have never worked with OpenStack before, but as I have been reading out there, the first thing I have to do is to install Devstack on a VM in order to be able to test the driver. However, I am really struggling on getting Devstack installed on the VM. The installer is always complaining about broken/incompatible dependencies, and when I try to fix them, it just takes forever to install.

            Following the official documentation does not work for me, it always complains about broken dependencies.

            Perhaps someone can point me to an exact distribution/OS version and an OpenStack version that will work for sure?

            I usually have to set HOST_IP in local.conf to my servers ip address as well.

            How can I disable the return_bind_key in PySimpleGui?
            Asked 2021-Nov-25 at 20:26

            I need to disable the bind_return_key parameter to false after a question is answered incorrectly. The parameter is binded to the submit button under the key 'b1'. I used the .update() method and it worked around a week ago. It not longer works and I receive this error: "TypeError: update() got an unexpected keyword argument 'bind_return_key'"

            Is there a fix to this?

            Things I've tried:

            • changed what is being updated from key 'b1' to 'Submit'

            This was an issue 2548 in PySimpleGUI.

            Since version 4.16.0 there is also a shortcut to unbind a key from an element:

            I've also added an Element.unbind method to match the Element.bind method. This will allow you to unbind tkinter events from an element without needing to access the element's Widget member variable.

            Thus you can use following to unbind tkinter's return key-press events ('') from your element, which is not the button (with key b1) but the input (text-field with key -INPUT-):

            Neutron LBaaS was removed from OpenStack in Train, so trying to add the provider for Octavia in Neutron won't work, and it isn't needed for Octavia to work.

            You most likely need to look at the Octavia logs to figure out why your load balancers aren't working.

            Vulnerabilities

            An issue was discovered in OpenStack Neutron 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By creating two security groups with separate/overlapping port ranges, an authenticated user may prevent Neutron from being able to configure networks on any compute nodes where those security groups are present, because of an Open vSwitch (OVS) firewall KeyError. All Neutron deployments utilizing neutron-openvswitch-agent are affected.
            An issue was discovered in the iptables firewall module in OpenStack Neutron before 10.0.8, 11.x before 11.0.7, 12.x before 12.0.6, and 13.x before 13.0.3. By setting a destination port in a security group rule along with a protocol that doesn't support that option (for example, VRRP), an authenticated user may block further application of security group rules for instances from any project/tenant on the compute hosts to which it's applied. (Only deployments using the iptables security group driver are affected.)
            Live-migrated instances are briefly able to inspect traffic for other instances on the same hypervisor. This brief window could be extended indefinitely if the instance's port is set administratively down prior to live-migration and kept down after the migration is complete. This is possible due to the Open vSwitch integration bridge being connected to the instance during migration. When connected to the integration bridge, all traffic for instances using the same Open vSwitch instance would potentially be visible to the migrated guest, as the required Open vSwitch VLAN filters are only applied post-migration. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3, 11.0.5 are vulnerable.
            When using the Linux bridge ml2 driver, non-privileged tenants are able to create and attach ports without specifying an IP address, bypassing IP address validation. A potential denial of service could occur if an IP address, conflicting with existing guests or routers, is then assigned from outside of the allowed allocation pool. Versions of openstack-neutron before 13.0.0.0b2, 12.0.3 and 11.0.5 are vulnerable.
            A race-condition flaw was discovered in openstack-neutron before 7.2.0-12.1, 8.x before 8.3.0-11.1, 9.x before 9.3.1-2.1, and 10.x before 10.0.2-1.1, where, following a minor overcloud update, neutron security groups were disabled. Specifically, the following were reset to 0: net.bridge.bridge-nf-call-ip6tables and net.bridge.bridge-nf-call-iptables. The race was only triggered by an update, at which point an attacker could access exposed tenant VMs and network resources.
            The openvswitch-agent process in OpenStack Neutron 2013.1 before 2013.2.4 and 2014.1 before 2014.1.1 allows remote authenticated users to bypass security group restrictions via an invalid CIDR in a security group rule, which prevents further rules from being applied.
            The L3-agent in OpenStack Neutron before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated users to cause a denial of service (IPv4 address attachment outage) by attaching an IPv6 private subnet to a L3 router.
            The default configuration in a sudoers file in the Red Hat openstack-neutron package before 2014.1.2-4, as used in Red Hat Enterprise Linux Open Stack Platform 5.0 for Red Hat Enterprise Linux 6, allows remote attackers to gain privileges via a crafted configuration file. NOTE: this vulnerability exists because of a CVE-2013-6433 regression.
            CVE-2015-8914 CRITICAL
            OpenStack Neutron before 2014.2.4 (juno) and 2015.1.x before 2015.1.1 (kilo), when using the IPTables firewall driver, allows remote authenticated users to cause a denial of service (L2 agent crash) by adding an address pair that is rejected by the ipset tool.
            The default configuration in the Red Hat openstack-neutron package before 2013.2.3-7 does not properly set a configuration file for rootwrap, which allows remote attackers to gain privileges via a crafted configuration file.
            The notifier middleware in OpenStack PyCADF 0.5.0 and earlier, Telemetry (Ceilometer) 2013.2 before 2013.2.4 and 2014.x before 2014.1.2, Neutron 2014.x before 2014.1.2 and Juno before Juno-2, and Oslo allows remote authenticated users to obtain X_AUTH_TOKEN values by reading the message queue (v2/meters/http.request).
            OpenStack Neutron before 2013.2.4, 2014.x before 2014.1.2, and Juno before Juno-2 allows remote authenticated users to cause a denial of service (crash or long firewall rule updates) by creating a large number of allowed address pairs.
            The IPTables firewall in OpenStack Neutron before 7.0.4 and 8.0.0 through 8.1.0 allows remote attackers to bypass an intended MAC-spoofing protection mechanism and consequently cause a denial of service or intercept network traffic via (1) a crafted DHCP discovery message or (2) crafted non-IP traffic.
            Race condition in OpenStack Neutron before 2014.2.4 and 2015.1 before 2015.1.2, when using the ML2 plugin or the security groups AMQP API, allows remote authenticated users to bypass IP anti-spoofing controls by changing the device owner of a port to start with network: before the security group rules are applied.

            Install neutron

            You can download it from GitHub.
            You can use neutron like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
