Hi,
I have installed content filter network extension which is almost same as https://developer.apple.com/documentation/networkextension/filtering_network_traffic.
I have another app. As part of this app, I am sending messages from server process to client process by using unix domain sockets which is almost same as https://github.com/devlights/go-unix-domain-socket-example.
If network traffic is little bit more then my client is failing to send messages with write: no buffer space available error. If I stop content filter network extension then there is no issue.
How can I handle this type of error with network extension?
Note: This is happening on both monterey and ventura mac os (both intel and m1).

remotePrefix: 0,
localNetwork: nil,
localPrefix: 0,
protocol: .any,
direction: .any)

My customer installed two different apps on his Mac machine. These two apps are using ContentFilter extensions. One of the app is mine and another app is different vendor.
If my customer enabled both ContentFilter extensions then he fails to connect immediately to its required destination to allow it to run. If one of the ContentFilter extension is disabled then there is no issue.
Is it not possible to run two different ContentFilter extensions on same Mac machine? Is there any way to fix these type of issues?
Thank You

Hi, I am using file provide extension to sync the app with remote storage. createItem() fileprovideer extension is calling when I copy a file and I able to sync properly with normal file and symlink files. itemTemplate.symlinkTargetPath helps me to sync symlink file.
But, I am facing the with alias file to sync. I tried to get original file name of alias file but I haven't found any option. How to get the original file name of alias file at createItem() of fileprovider extension. Is there any way to sync alias file?
My createItem() sample code at extension which sends the call to server through grpc.
public func createItem(
basedOn itemTemplate: NSFileProviderItem,
fields: NSFileProviderItemFields,
contents contentsUrl: URL?,
options: NSFileProviderCreateItemOptions = [],
request: NSFileProviderRequest,
progress: Progress
) async throws -> (NSFileProviderItem, NSFileProviderItemFields) {
var (templateAttributes, _) = self.load(fields: fields, from: itemTemplate)
templateAttributes.ownerAccountID = getuid();
templateAttributes.groupOwnerAccountID = getgid();
let identifier: NSFileProviderItemIdentifier
let attributes: FileProviderItemAttributes
if itemTemplate.contentType?.conforms(to: .directory) == true {
// Handle folder creation
.....
.....
} else if itemTemplate.contentType?.conforms(to: .symbolicLink) == true {
// Handle symlinks
guard let targetPath = itemTemplate.symlinkTargetPath else {
fatalError("couldn't get symlinkTargetPath on \(itemTemplate)")
}
....
....
}
else if itemTemplate.contentType?.conforms(to: .aliasFile) == true {
// TODO I am not yet handled this case. I need to get original path of alias file.
}
else {
// Handle file creation
....
....
}
let item = try FileSystemItem.any(filename: itemTemplate.filename,
identifier: identifier,
parentIdentifier: itemTemplate.parentItemIdentifier,
attributes: attributes)
return (item, [])
}

HI,
I want to know whether my extension is in active state or not as part of my swift application.
It would get this on terminal usingsystemextensionsctl list | grep FilterExtension | grep activated command. It can be possible with system() on C++ as system("systemextensionsctl list | grep FilterExtension | grep activated")
But how can I achieve this in swift language?
Help me.
Thanks.

HI,
I am using Content Filter simple firewall Network Extension (NE). I have couple of doubts about NE deactivation. Please clarify.
Is it possible to deactivate the NE without user consent?
If not possible without user consent, why we need to authorise even for deactivate? Is it restricted by Apple?
Please clarify.

int *ret = request;
I am trying to do same thing in Swift also. Here 'request' type is 'UnsafeMutableRawPointer' But I am facing with error
"Cannot convert value of type 'UnsafeMutableRawPointer' to specified type 'UnsafeMutablePointer<Int32>'" let ret: UnsafeMutablePointer<Int32> = request
Any one please help to convert from UnsafeMutableRawPointer type to UnsafeMutablePointer<Int32>.

Hi, I am new to Swift language. I am trying to convert below C++ function to Swift function as below.
C++ function:
int test(test_type type, request_info_t *request, size_t request_len)
{
size_t size = request_len;
int mib[] = {0,0,0,0,0};
int ret = sysctl(mib, 5, request, &size, NULL, 0)
return ret;
}
Swift function:
func test( type: test_type, request: request_info_t, request_len: size_t) -> Int64
{
let size: Int = request_len
let mib: [Int]= [0, 0, 0, 0, 0]
let val: Int32 = sysctl(mib, 5, request, size, nil, 0)
return val
}
But I am facing below issues with arguments at sysctl(). Could any one please to convert this. Error due to first argument mib: Cannot convert value of type '[Int]' to expected argument type 'UnsafeMutablePointer<Int32>?'
Error due to third argument request: Cannot convert value of type 'Int' to expected argument type 'UnsafeMutablePointer<Int>?'
Error due to fourth argument size: Cannot convert value of type 'requestinfot' to expected argument type 'UnsafeMutableRawPointer?'
