I am trying to create an application extension which provides vpn functionality over network extension with packet-tunnel. But when I enable vpn it doesn't call related callbacks.
Currently, i didn't find any example in qt documentation. So I read the documents of ios and qt and trying to find the right path.
Here is the CMakeLists.txt
add_executable(overlay-service MACOSX_BUNDLE main.cpp tunnel_provider.h tunnel_provider.mm)
set_target_properties(overlay-service PROPERTIES
MACOSX_BUNDLE_IDENTIFIER org.zenarmor.zenoverlay.network-extension
BUNDLE YES
XCODE_PRODUCT_TYPE com.apple.product-type.app-extension
# XCODE_EMBED_FRAMEWORKS /System/Library/Frameworks/NetworkExtension.framework
)
target_link_libraries(
overlay-service
PUBLIC
Qt6::CorePrivate
overlay-lib
)
tunnel_provider.h
#ifndef _TUNNEL_PROVIDER_H
#define _TUNNEL_PROVIDER_H
#import <Foundation/Foundation.h>
#import <NetworkExtension/NetworkExtension.h>
@interface ZenTunnelProvider : NEPacketTunnelProvider {
int fd;
}
- (void) startTunnelWithOptions:(NSDictionary<NSString *,NSObject *> *) options
completionHandler:(void (^)(NSError * error)) completionHandler;
- (void) stopTunnelWithReason:(NEProviderStopReason) reason
completionHandler:(void (^)()) completionHandler;
@end
#endif
tunnel_provider.mm
#import <Foundation/Foundation.h>
#import <os/log.h>
@implementation ZenTunnelProvider
- (void) startTunnelWithOptions:(NSDictionary<NSString *,NSObject *> *) options
completionHandler:(void (^)(NSError * error)) completionHandler {
NSLog(@"===================== Tunnel Started, x=%i, %@", 5, self.protocolConfiguration);
completionHandler(nil);
}
- (void) stopTunnelWithReason:(NEProviderStopReason) reason
completionHandler:(void (^)()) completionHandler{
NSLog(@"===================== Tunnel Stopped");;
completionHandler();
}
@end
How I create configuration is:
provider_protocol.providerBundleIdentifier = @"org.zenarmor.zenoverlay.packet-tunnel";
provider_protocol.serverAddress = @"0.0.0.0";
provider_protocol.providerConfiguration = @{
@"helloString" : @"Hello, World!",
@"magicNumber" : @42
};
NSLog(@"===================== Vpn configuration is written, x=%i", 5);
vpn_manager.protocolConfiguration = provider_protocol;
vpn_manager.localizedDescription = @"ZenOverlayTunnel";
vpn_manager.enabled = true;
[vpn_manager saveToPreferencesWithCompletionHandler:^(NSError * _Nullable error) {
if (error)
{
NSLog(@"err: %@", error);
}
else
{
NSLog(@"Successfully saved");
}
}];
main.cpp
#include <QCoreApplication>
#include <iostream>
int main(int argc, char **argv)
{
QCoreApplication app(argc, argv);
std::cout << "Hello world" << std::endl;
return app.exec();
}
startTunnelWithOptions is not triggered when I enable vpn from settings on IOS. Could anyone. help to identify the issue?
