- ListSupportedNetworkServiceProvidersCmd will now return Providers along with its element's services and boolean 'canEnableIndividualServices' that indicates if for this Provider services can be enabled/disabled
- add & update NetworkServiceProvider changed to take in the list of services to enable. While adding a provider, if list is null then all services supported by the element are enabled by default.
- ListNetworkServices enhanced to take in a provider name and returns services of that specific provider.
2)Re-apply all existing firewall rules as a part of implement call. TODO: Cleanup all existing rules from the backend (leave them in the DB) as a part of shutdown call
In the past, the NetworkElement would cover almost all the functionality that
e.g. virtual router can cover: firewall, source NAT, static NAT, password,
VPN... So anyone want to implement the NetworkElement would have to implement
these service's specific methods, even it wouldn't support it. Also, if we want
to find a e.g. FirewallServiceProvider, we have to proceed all the current
network service providers, to call a method to know if it support such service.
That's neither elegant nor scaling way to do it.
As the first step, this patch separates each ServiceProvider from NetworkElement
(there are some interface already out of NetworkElement, so this patch slightly
modifies them too), and only the class would implement the correlated interface, would
have the ability to do these services.
1) On enableStaticNat command we actually send the command to the backend (we used to just upgrade the DB in the past). The backend command carries sourceIp and destIp, and creates IP to IP mapping on the domR.
2) On disableStaticNat for the Ip address in addition to cleaning up port ranges, we also delete IP to IP mapping on the domR.
