We restricted the thread count to always be one
When attempting to debug some issues, I overrode the number of threads processing packets and set it to one. Need to undo that and push a new release. Might as well fix the broken IDiverter interface while I'm at it, which should enforce the optional thread argument.
Null checks are missing from WindowsDiverter
Wherever we call GetLocalPacketInfo, we don't always check for null. This is an issue, because it's quite possible for the function to return null.
Move "Test" project out to a "Examples" solution
Can not block a website using AJAX
Hi there!
I used CitadelCore.Windows to block some url and it work very well. But if a website uses AJAX, it seems can't block the url.
I tried to block some url of Youtube but notthing happened.
Sorry for my bad English.
Regard!
Can't delete WinDivert64.sys
Hi Jesse!
I am trying to delete WinDivert64.sys file and the system complains it is still in use. CitadelCore is of course terminated. What is the reason for this behaviour?
Currently, the only way I found is to restart computer. What is the programmatic approach?
filter by SNI name
If I am understanding the code correctly, OnFirewallCheck(FirewallRequest request) in program.cs is meant to decide weather to filter or not. So far, I've used the ip addresses and compared them to the known ips that I'd like to filter. The problem is that domains stay the same and servers (along with IPs) change.
The approach I wanted to try out is to inspect SNI server names in TLS client hello packages. The problem is that HandleNewTcpConnection is called before client hello is sent, and you only get to decide based on ips. Am I missing something or is this the end of story with regard to SNI filtering?
Move WinDivert out into its own package, change license
We really should, because of scenarios like #9 , move WinDivert into its own independent package.
Once we do that, we can also move things to the MPL 2.0 license, which is how I typically prefer to license my work.
Can’t use CitadelCore behind a proxy
I am testing CitadelCore and it works great. However, I found that it can’t filter traffic when system is connected to another proxy. I tried SSH tunneling (ssh -D port user@ip) and squid web proxy. Neither worked.
Is this a known limitation? What is the cause of it?
UDP6 needs to be added to QUIC drop filter string
Chrome can escape IPV6 filtering for google services (google images, gmail, youtube etc) because UDP6 is not included in the QUIC filtering string.
When using CitadelCore.Windows cannot upload image files via facebook, I can't use google translate
Fix Travis w/ config
Can not access website after remove it out block list.
Hello,
I made an application read domains from file and block it, when file change the app read file again and block only domains in file. Example I have file domain.txt below:
phimmoi.net
vnexpress.net
First application work ok (it blocked domain phimmoi.net and vnexpress.net), then I delete phimmoi.net domain from file and hope can access phimmoi.net now but when I access phimmoi.net from browser it show below error in console and browser can not access phimmoi.net. I guest this proxy cache blocking this domain. Please help to check this issue.

What files are actually needed to run?
Hi there,
Thanks for your project.
It runs fine when building, but I'm not sure what dlls are needed. When moving the executable+windivert dlls, it isn't working any more.
The build folder has like 50 Micoroft.net framework files.
Speed increase by preestablishing MITM-SERVER connection
I noticed that the initial connections to websites are very slow. This is only true for the very first one, all subsequent refreshes gain significant speed boost. I understand that in order for CitadelCore to work, it need to establish 2 SSL/TCP connections. One between client and mitm(Kestrel) and one with HttpClient and endpoint server. Moreover, delay for 3 roundtrips needed should be minimal between client and mitm, and very noticable between mitm and server. I expected that the website load(initial request) time should be decreased (or at least stay the same), if the connection between mitm and server is preestablished.
I tested this idea and implemented a small piece of code in FilterResponseHandlerFactory.cs. On line 94, I added a request to desired website.
_client = new HttpClient(configuration.CustomProxyHandler, true);
HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Get, "https://motherfuckingwebsite.com/");
requestMessage.Headers.Add("Host", "motherfuckingwebsite.com");
requestMessage.Headers.Add("Connection", "keep-alive");
requestMessage.Headers.Add("Pragma", "no-cache");
requestMessage.Headers.Add("Cache-Control", "no-cache");
requestMessage.Headers.Add("Upgrade-Insecure-Requests", "1");
requestMessage.Headers.Add("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.4044.155 Safari/537.36");
requestMessage.Headers.Add("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9");
try{
HttpResponseMessage response = _client.SendAsync(requestMessage).GetAwaiter().GetResult();
if (response.StatusCode == HttpStatusCode.OK){
Console.WriteLine("prefetch done");
byte[] buf = response.Content.ReadAsByteArrayAsync().GetAwaiter().GetResult();
string content = Encoding.UTF8.GetString(buf);
}
}
catch (Exception e){
// handle error
}
I got a 450ms speed increase on first page load compared to no prefetching and 150ms delay, compared to no mitm. I then changed the host and testes for different websites (such as 9gag.com), and got a large deviation from the expected. The speed increase was negligible. 20ms tops, and I am not even sure about that due to network randomness.
What is your take on this approach? The goal is to optimize first page load. Do you have any implementation recommendations?
Ignoring imposter packets may be the wrong thing to do
I think I was a little hasty and under-studied when I ignored the imposter packets in the diverter.
NewHttpMessageHandler is keep getting invoked, even though connection is dropped.
Hello there!
I've made an example URL filtering application and it works so far so good. It blocks the connection and the specific element doesn't appears on the browser. I'm also trying to analyze to see which filters are being used more frequently than the others. It basically keeps count of blocked URLs into a text file. This also works okay but sometimes it starts to block an URL over and over and over again for literally no reason. Even if I close the browser, it'll keep blocking it.
Can not access FTP or SSH
Hello,
I run the test program and it worked good, but I can not connect FTP or SSH when the program running (I can connect when I turn off the program).
Please help to check this problem.
Thank you!

@TechnikEmpire can you take a look ?
Handling of websocket connections close event
On websocket termination (triggered by browser tab closure), a number of catch blocks catch an exception. The relevant code and stack trace is appended. I normally just ignore these errors and I haven't noticed any problems because the thing you are doing is already done after the connection is closed. So apart from cluttering the error logs, they appear to be benign. But I wonder.. Do they cause any side effects and should they be prevented? The code is from FilterWebsocketHandler.cs and FilterHttpResponseHandler.cs .The below stack is generated by tab close event. Thank you.

Possible bug in port mapping arrays
I think the port mapping arrays should probably have a size of 65535+1 (ushort.MaxValue + 1) because of zero based indexes. In theory there could be ::1:65535 for example, which would throw an out of bounds exception in the windiverter code.
propagating invalid SSL certificate error to the browser
I noticed that you get notified of an SSL cert error only through try/catch block of upstream HttpClient request. By that time, https connection with the browser has long been established and the browser happily shows the lock icon.
I opened TlsSniConnectionAdapter and found only hooks for SNI inspection via StreamExtended API. Does Kestrel have an option for intercepting certificate sent from remote machine much like it is capable of intercepting ClientHello messages?
IPV6 system process detection is wrong
The packet diversion process thinks that PID 6 on a v6 packet means system when in fact it's PID 4.
Upgrade to WinDivert 1.4.x
There's been a couple of pretty critical issues arise between our current version of WinDivert (1.3) and the latest version, which need to be addressed. We need to upgrade.
Proxy intercepting is unstable
It seems that WinDivert driver doesn't intercept traffic for processes started after CitadelCore.
For example, all browsers need to be restarter if they were launched before the CitadelCore. I am not able to reproduce this issue on all occasions, but it happens very often.
Is this a bug or a known limitation?
