High CPU usage after looking for Yubikey devices #13

Closed obacker-snapcode closed 1 year ago

obacker-snapcode commented 2 years ago

Hello!

Integrated the sdk in a desktop app and realized that it suddenly saw constantly high cpu usage. I moved this bit of code out to a console application:

var devices = YubiKeyDevice.FindAll();
await Task.Delay(-1);

Just this alone seems to be using alot of cpu, with or without inserted yubikey. After a quick inspection with dotTrace the api seems to be looking constantly for new inserted keys.

Whilst I imagine the high cpu usage is unintended, is there even a way to turn off this feature of background checking?

GregDomzalski commented 2 years ago

What version of the SDK are you using?

Are you inserting more than one YubiKey in the system?

There was a bug in 1.2.0 that was addressed in 1.3.0 that cause high CPU usage on Windows in these cases. Based on the call tree you provided above (thanks for that!) it looks like it could be this same bug. Or, if you're on the latest 1.3.1... maybe there's yet another scenario that can trigger it.

Unfortunately, no, there's no way to shut off the background listener at this time.

olabacker commented 2 years ago

I'm using version 1.3.1.

I'm using either one or no yubikeys connected. After the FindAll() method has been executed the background listener seems to consume some cpu regardless, one core at 100% it seems.

I've just glanced quickly in the source but it seems that there is no sleep duration in between the endless checking of devices but I might be wrong.

GregDomzalski commented 2 years ago

Hmm. That's concerning if you're still encountering this in 1.3.1.

The call to SCardGetStatusChange is supposed to block until there is a difference in the system to report. Once we've processed all of the EventStates, we copy that over to the CurrentState, and the API will again block until there is something new in the EventState.

At least that's what's supposed to happen. My guess is that this process is not quite happening properly.

Can you gather some logs for us? I'm using Serilog in the below example code because it supports adding thread IDs to the messages, which is helpful in this case. It logs to the console, but you may want to modify it to log to a file directly, instead.

    class ThreadIdEnricher : ILogEventEnricher
    {
        public void Enrich(LogEvent logEvent, ILogEventPropertyFactory propertyFactory)
        {
            logEvent.AddPropertyIfAbsent(propertyFactory.CreateProperty(
                "ThreadId", Thread.CurrentThread.ManagedThreadId));
        }
    }
// Put anywhere early on in your app, preferably before you first enumerate the
// SDK as that's when the listeners start.
            using var log = new LoggerConfiguration()
                .Enrich.With(new ThreadIdEnricher())
                .WriteTo.Console(
                    outputTemplate: "[{Level}] ({ThreadId})  {Message}{NewLine}{Exception}")
                .CreateLogger();

            Core.Logging.Log.LoggerFactory = LoggerFactory.Create(
                builder => builder
                    .AddSerilog(log)
                    .AddFilter(level => level >= LogLevel.Information));

Sure!

In the minimal example I provided before I simply added the logging capabilities you asked for. The logs start out like this and continue endless. This is the result on two different computers running win11.

Fascinating. So not only is the SDK chewing up 100% of one of your cores, it doesn't look like it's really working much at all. It looks like it was able to find the YubiKey over the keyboard interface, but that's it.

It looks like the SDK is unable to communicate with the smart card subsystem on Windows. And for some unknown reason, it is continuing along as if it can. I would have thought we'd have thrown an exception here... I'll have to do some digging into why it's not stopping when it clearly shouldn't continue.

Any idea why your application isn't able to talk to the smart card subsystem? I'll have to spin up a Windows 11 VM and try this out for myself. Any chance your app is running inside of a sandbox / UWP container?

olabacker commented 2 years ago

Yes, the yubikey (neo) is found if inserted and I can do operations on it, which works fine.

I'm not sure what exactly the smart card subsystem in windows is, but I'm not using any smart cards of any kind.

I noticed the problem when I integrated the sdk into a WPF app (net6). Immediately afterwards I isolated the issue to a console application (net6) only containing the two lines in my original post (and then added your serilog code). Both of these apps (wpf and console) have the same problem on both win11 machines I tried it on. Both are running win11 natively so no vm.

If there is anything more I can help with logs or something else since it is easily reproducible here please let me know!

olabacker commented 2 years ago

Another thing to add to the smart card discussion..

I realized the yubikey the has a CCID feature which was disabled when I checked the yubikey manager. I only use OTP (currently).

If I enable this interface the FindAll() method will not complete successfully and instead throw the following exception

Yubico.PlatformInterop.SCardException
