In what context (or rather in whose thread) does the callback code (functions like sf_bind_func) operate? What if i am waiting there for a usermode process to send me some command via kernel_control? What else will freeze, except my function? the whole networking subsystem? In what context myNKE_start() and myNKE_stop() are executed? What if i perform some lengthy operations in there? What about kernel_control's callback functions? If i am, for example, establishing a connection with a remote host (which is not a quick action), from "EPHandleGetSockOpt", will only usermode process, which called "getsockopt", freeze? Or something else will degrade as well? What is the common rule to perform such operations? Creating my own thread and waiting for callbacks from it?

Setting up a kext for debugging according to Apple's instructions is quite tedious, labor-intensive and error prone. It takes a long time for each round of compile, test and debug. You'll go out of your tree in short order if you keep typing all those commands by hand. Once you are quite certain you know how to set up a kext for debugging, write a BASH shell script that does all that for you instead. I did, and it changed my life in an incredibly positive way. I'm sorry, but I had to reformat my drive quite unexpectedly a while back so I don't have my script anymore, but it's not hard to write. If you don't know how to write shell scripts, just google for: unix shell tutorial ... and you'll be scripting in no time. It's really best to use two Macs for kext debugging, so if you panic your kernel on the test machine, your development machine is not affected. When testing buggy kexts, there is always the possibility that a crash can cause filesystem corruption, despite the journaled HFS+ filesystem. I do realize that you might only own one Mac, but if you ARE using two, have that shell script scp your kext from your dev machine to your test machine. See "man scp" in the Terminal. You can give ssh on your test machine a short script that it will execute on your dev machine. Have that script tar or zip your kext, transfer the compressed archive to your test machine, put that archive in the test machine's /tmp directory, unpack the archive so it's a kext bundle again, then use "sudo cp -R" to copy it to the /System/Library/Extensions folder. Then have your script get GDB and the addresses and stuff set up. You'll be glad you did. ;-) Mike -- Michael David Crawford mdcrawford at gmail dot com Custom Software Development for the iPhone and Mac OS X http://www.dulcineatech.com/custom-software-development/ _______________________________________________ Do not post admin requests to the list.
