Specified IP addresses can be listened to to prevent risks caused by all-zero listening

[five111]

Specified IP addresses can be listened to to prevent risks caused by all-zero listening.

Motivation:
When I used Nacos, I noticed that the jraft port was listening on all zeros. Upon reviewing the Nacos source code, I found that it passed an IP address when creating the jraft server, but sofa-jraft still opted to listen on all zeros, which could introduce some security risks.

Modification:
Determine whether the incoming endpoint contains an IP address. If it does, listen directly on that IP; otherwise, continue to listen on all interfaces with an IP address of 0.

Result:
Specified IP addresses can be listened to to prevent risks caused by all-zero listening.

Walkthrough

The code updates the gRPC server instantiation in the GrpcRaftRpcFactory class to use NettyServerBuilder with an explicit InetSocketAddress, replacing the previous use of ServerBuilder with a port. The change also updates the import statement to use the Netty-specific builder and adds a check for a non-blank IP address.

Changes

Cohort / File(s)	Change Summary
gRPC Server Builder Update jraft-extension/rpc-grpc-impl/src/main/java/com/alipay/sofa/jraft/rpc/impl/GrpcRaftRpcFactory.java	Replaced ServerBuilder with NettyServerBuilder, constructing the server using forAddress and an explicit InetSocketAddress based on endpoint IP and port. Added StringUtils.isNotBlank check for IP. Updated import accordingly.

Poem

A hop and a leap, the server's address is set,
Netty now builds where plain ports once met.
With sockets explicit, connections grow strong,
In gRPC meadows, the code hops along.
