Hi, I'm writing a kext that uses the kauth facilities and was wondering whether it is possible to wait for user input from a userland application connected to the kext through an IOUserClient object in the middle of making the decision of whether or not a file system operation will be allowed. Essentially I would like to send a notification to the user in my kauth_listener function, wait for their decision, and then decide based on that whether to allow or disallow the file system operation in question. I haven't worked in the kernel before and am worried that this behavior may cause the entire system to hang. This email sent to site_archiver@lists.apple.com
