The closest thing i came up with - is to somehow "ask" the process if it is "mine", right in "filter_attached_to_socket" NKE's callback. I am searching for the way to 'ask' it, it should be some kind of IPC, but i am not sure which one. The only thing i was using for kernel-userland communication were Control Sockets, but the conversation for these is initiated by an application not the kernel extension (while i need a driver to ask the application, not vice versa, - of course with all error checking and "app not responding/not loaded" correct processing). I am not even sure if that is possible to do at all.
The way I've seen this done (using other mechanisms) is to have your userspace code have a thread that makes a call into the kernel and the kernel call just blocks. When the kernel wants to ask the userspace code to do something, it does that by having the blocked userspace call complete. Seems like that could work here. The only other option ... well, I'm not sure you can easily do it yourself, but look at bsd/nfs/nfs_gss.c, specifically nfs_gss_clnt_gssd_upcall(). I would caution you that I'm not sure that you can make use of that yourself, but it's at least worth looking at. --Ken _______________________________________________ Do not post admin requests to the list.
