while activating and starting the network extension the user sees prompts which he/she has to act on .
but in an enterprise environment the activation process need not have the user who would click on these prompts .
so how is such scenario handled in activating system extension in enterprises .
do we have any control on prompts , may be by authenticating through a silent process which might be controlled by administrator remotely during the deployment ??

:- can 2 system extensions be hosted in same container appp ?
: - And is it a recommended approach or every extension must be hosted in a separate container app ?
when I install the Network extension I see 2 prompts :
1 is the prompt in Security And Privacy where the system ext is blocked and have to allow it after giving password
2nd is when I save the preferences (network ext) I see the Allow/Deny prompt .
for 1st prompt it seems it displays the name of the product name of the container app .
where is the name & icon taken for the 2nd allow / deny prompt ? how to modify it ?
After using OSSystemExtensionRequest deactivationRequestForExtension for Network Extension and after a reboot the extension is still seen with the status "uninstalling"
so it looks like we require 2 reboots for deactivating the Extension.
is it a known behaviour for system extension?
how to achieve this with only 1 reboot programatically (not via systemextensionsctl reset) ?
I have to capture all traffic for only a particualar remote IP (e.g. 30.40.50.60) . i have tried to set NEFilterRule for NEFilterDataProvider as follow :
host= [NWHostEndpoint endpointWithHostname:@"30.40.50.60" port:@"0"]
Rule= [[NENetworkRule alloc] initWithDestinationNetwork:host prefix:0 protocol:NENetworkRuleProtocolAny];
FilterRule = [[NEFilterRule alloc] initWithNetworkRule:Rule action:NEFilterActionFilterData];
FilterRuleArray = [NSArray arrayWithObjects:FilterRule, nil];
FilterSettings = [[NEFilterSettings alloc] initWithRules:FilterRuleArray defaultAction:NEFilterActionAllow];
[self applySettings:FilterSettings completionHandler:^(NSError *error){}];
somehow I am still getting all the traffic in handleNewFlow . i wan it only for the particular IP address .
not sure what is wrong here . any pointer on this will help .
I am implementing Network Extension - NEFilterDataProvider.
checking whether we get IP address and port for the flow in handleNewFlow ?
how do we fetch the IP address & Port in this type of Network Extension (socket level ) ??
any pointer would help
seeing this error when I am trying to install my network extension:
_macvnodechecksignature: /Applications/abc.app/Contents/MacOS/abc: code signature validation failed fatally: When validating /Applications/abc.app/Contents/MacOS/abc:
Code has restricted entitlements, but the validation of its code signature failed.
Unsatisfied Entitlements:__
I have set the right entitlements as far as I know . is this error about entitlements or signature that is not obvious from the message .
this is sseen on Catalina 10.15.6
the macOS Network extension is Developer ID signed .
still facing this error . any idea what will fix this error ??
are handleNewFlow for NEFilterDataProvider Network Extension serialised ?
can we assume that the flows would never come in parallel ?
thank you .
struggling to set NEFilterRule for NEFilterDataProvider in order to filter (or for that matter allow) all the traffic.
have tried following :
[NWHostEndpoint endpointWithHostname:@"0.0.0.0" port:@"0"]
[NWHostEndpoint endpointWithHostname:@"" port:@"0"]
[NWHostEndpoint endpointWithHostname:@"0.0.0.0/0, " port:@"0"]
[NWHostEndpoint endpointWithHostname:@"0.0.0.0/0, ::/0" port:@"0"]
nothing of the above works .
how to construct the NWHostEndpoint in order to handle all the traffic .
thank you .
i have basic question .
I need to comunicate data / message between a System Extension and application (this is not the container app for System Extension ).
which IPC mechanism is recommended ?
is socket communication good for the same ?
can system extension be hosted in a dylib instead of an app ?
I can load the dylib from an app .
Is it possible to do so or an app is mandatory to host system extension ?
is "App Sandbox entitlement" required for Driverkit ?
is it necessary to remove "App Sandbox entitlement" capability for Network extension ?is the above requirement also hold for all system extension ?
when i activate network extension it is seen as activated enabled ; but when i deactivate it shows that it is terminated but waiting for reboot.i always thought the activation-deactivation thingy doesn't require any reboot . can you please guide ?
it is clear that network extension can intercept the traffic from safari .;does it also intercept the traffic from chrome, edge, firefox and opera ?
