Matching Multiple Services?

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Is it possible to use IOServiceGetMatchingServices() to match with a logical-OR configuration? I need to find several (3) different types of services. Is there some way to build a dictionary that could find all three of them at once?

Again, I'd like to thank you all for the constructive debate. I'm most probably going to handle extended attributes within userland with a char device communicating results to the kernel extension. Also, I'm going to fill a decent request to bugreport.apple.com to see if I can get the thing into the mainstream kernel.. Regarding that, how much chances do you think I have for that to happen?

Re: [darwin-dev] reading /dev/random from a kext

The code for encrypted swap in xnu-792.18.15/osfmk/vm/vm_pageout.c just casts calls to libkern's random() into a char[] buffer. The security properties of random() aren't guaranteed I guess, though the implementation is calling read_random() internally.

If that connection is closed then the disk can be ejected. Clearly I'm at fault here, so I am looking for suggestions. You must not keep the provider open when you have no clients that have you open in Storage Family. It is a lazy open scheme. We realize that someone has it open at the block storage driver and deny the ejection there. Hell Folks, I'm working on a file system filter kext. The kext fails to unload and the disk it is attached to fails to completely eject. By completely eject, I mean that the volume is removed from the Finders desktop, but disk utility still shows the disk and the volume grayed out. (The volume can even be remounted.) Selecting the disk in disk utility and selecting Eject gives an error message indicating open resources. For various reasons, the kext keeps an open connection (using open()) to it's provider. If that connection is closed then the disk can be ejected. Clearly I'm at fault here, so I am looking for suggestions. Note that if the disk is removed (ie a flash drive), the kext cleans up and is removed because I override willTerminate() to clean up. Clearly this is too late. I'd like to find out what I can do to determine that the disk is trying to be ejected so that I can clean up and remove my connection. I have no problem removing the connection, I just need to know when. I've looked at the terminate chain (terminate, requestTerminate, willTerminate, terminateClient) but those are too late. They seem to be called when the media is removed and you have no choice. _______________________________________________ Do not post admin requests to the list. They will be ignored.
