This bug was introduced due to the change from the old descriptor models into the new SOL006 descriptors. The Resource Orchestrator (RO) didn't received the information relating to port security, therefore it couldn't determine if the network interface should have it enabled or disabled, which in turn always applied the default for the used substrate. - | Fixes [bug 1408](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1408). This bug was introduced due to the change from the old descriptor models into the new SOL006 descriptors. The Resource Orchestrator (RO) didn't received the information relating to Virtual Link Descriptor (VLD) IP Profile, therefore it couldn't apply the desired values for subnets and DHCP. - | Fixes [bug 1446](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1446). This bug was introduced due to the change from the old Resource Orchestrator to the new Next-Generation Resource Orchestrator. For some Network Services, we have observed that sometimes the NS remains in state BUILDING. Checking in the database for ro_task we have seen that this happens because the RO keeps on locking always the same ro_task that has dependencies on another ro_task that is never executed. - | Fixes [bug 1445](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1445). This bug was introduced due to the change from the old Resource Orchestrator to the new Next-Generation Resource Orchestrator. When we try to instantiate a service with SRIOV interfaces it fails. Debugging the error we have seen that the mac does not arrive to the onosof sdn plugin. - | Fixes [bug 1386](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1386). This bug was introduced due to the change from the old Resource Orchestrator to the new Next-Generation Resource Orchestrator. RO has a database locking system intended for HA. Every worker locks a "ro_task" by writting at database, before performing it at the VIM, and unlocks afterwards. In case of a crash (e.g. POD is destroyed) the ro_task becames locked during many time until lock expires. The expiration time is set to 1 hour as this is the time that can take some ro_task (some VMs can take this time). It will be better having a shorter expiration time, and re-new it when needed if the thread that perform the VIM task is still alive. In that a way after a crash, new RO POD will take over the locked ro_task quite soon. The change has a new asyncio task that performs the renew of the locks of all the needed vim_threads. Vim_thread cannot do it by themselves because some VIM plugin operations are synchronous. - | Fixes [bug 1385](https://osm.etsi.org/bugzilla/show_bug.cgi?id=1385). This bug was introduced due to the change from the old Resource Orchestrator to the new Next-Generation Resource Orchestrator. Code creates vim_threads when there is new VIMs to handle (NS deployed at this VIM). However when the VIM is not used anymore (NS is deleted), vim_thread is not re-used in the next assignation. This is something that can be easily see with the logs. This bug does not causes malfunction, but can lead to have some threads overloaded. In addition resources are not free when VIM is not used. other: - | The code has been reformatted to be compliant with the Python Language standards, using [black](https://github.com/psf/black) and [flake8](https://flake8.pycqa.org/en/latest/).
