Detailed implementation of the function of deleting subchains using IOemNetd in the Android system
In the Android system, iptables is a commonly used tool for configuring and managing network rules. However, the Android system imposes some restrictions on the use of iptables, one of which is to prohibit direct deletion of subchains. In order to bypass this limitation, we can use the IOemNetd interface to implement the function of deleting subchains.
IOemNetd is a low-level network daemon process in the Android system, which provides a set of native interfaces for network management. By using the IOemNetd interface, we can bypass iptables restrictions and be able to delete subchains.
The following is a sample code that uses the IOemNetd interface to implement the function of deleting a subchain:
import android.os.IBinder;
import android.os.Parcel;
