RPC: add/remove -rpcallowip and -rpcauth options without restart

[hebasto]

Running the Bitcoin Core at a university for research purposes. Researchers use RPC to have an access to the Bitcoin Core via a LAN. Their credentials are stored in the bitcoin.conf file as pairs of rpcallowip=<ip> and rpcauth=<userpw> options.

From the Core operator's point of view, it seems two features are a feature is missing:

• an ability to add/remove -rpcallowip and -rpcauth options without the Bitcoin Core restart
• preventing to stop the Bitcoin Core from a remote machine by bitcoin-cli stop (a special case of a more general RPC Whitelist Files #12248)

For your second point, are you thinking of adding a separate config parameter for disabling an rpc shutdown?

[emilengler]

See #16544. This could fix your second point

Could be related: #12248

I have a project that does something similar to this, it can be configured to fit your use case I believe.

This is a duplicate of #12248? If not, it should specify how this feature request is different.

An ability to add/remove -rpcallowip and -rpcauth options without the Bitcoin Core restart is not covered by #12248.

Ok, maybe create a separate issue for that? A title of "feature request" with two features in the comment body isn't helpful to keep track of issues.
