To determine the real name of the symbols, use "c++filt" on the symbol name, with the extra underscore _ removed from the beginning of the symbol name. For example: c++filt _ZN26com_linsys_driver_receiver11getWorkLoopEv c++filt _ZN26com_linsys_driver_receiver15handleInterruptEv c++filt _ZN26com_linsys_driver_receiver16enableInterruptsEv c++filt _ZN26com_linsys_driver_receiver16interruptOccuredEP8OSObjectP22IOInterruptEventSourcei Gives you symbol names of com_linsys_driver_receiver::getWorkLoop() com_linsys_driver_receiver::handleInterrupt() com_linsys_driver_receiver::enableInterrupts() com_linsys_driver_receiver::interruptOccured(OSObject*, IOInterruptEventSource*, int) This looks like you don't have your super class correctly setup for your com_linsys_driver_receiver class.

The fewer setuid root tools that exist, the better. /bin/ps is already there, and is a pretty solid piece of code that probably doesnt have a lot of security problems left inside of it. It is a fairly heavyweight way to find out process status though. It's unfortunate that progrms like Jeffrey's and mine that previously did not need any root privileges or setuid helpers now need them, especially just to do something like find out the status of a process that our programs spawned - even though we can still kill them, suspend them, and find out their exit status. -Erik _______________________________________________ Do not post admin requests to the list.

(We retrieved the source for ps and found the task_for_pid () call). Alas, task_for_pid has gone privileged on Intel, and since ps is SUID root, I assume ps is still using task_for_pid. But we can't, since we're not (and don't want to be) run as root. Is there another non-privileged, reasonably cheap way to collect cputime stats for our child processes that are still running without resorting to shelling out/ popen()ing ps? We only care about processes owned by our UID. Wait4() is too late, because we want incremental stats, not just the ending stats. Our users are used to watching "das blinkenlights" :-). As long as your app is fork/exec'ing its own children you have options. The easiest, if you have control over the source, might be to have your children checkin with their parents and offer up their task port. The security gestapo can't stop what is freely given. If you do not have control over the source, you can still use this method by compiling the checkin code as an init routine of a simple shared library file, and getting it to run in the client by using DYLD_INSERT_LIBRARIES. I have some, arguably too simplistic, sample code demonstrating this procedure at http://www.phasic.com/~arwyn/checkin_server.c This email sent to site_archiver(a)lists.apple.com

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… Whenever I add IOWorkLoop and try loading the kext, I get the following error. kextload: kld_load_from_memory() failed for module /Users/dineshbhat/receiver/build/Release/receiver.kext/Contents/MacOS/receiver I checked the build settings to see if the driver name is set to com_linsys_driver_receiver. I also checked the build version. They all match fine. The IOBundleLibraries that I have added are kernel,mach and iokit with version 6.9.9. uname -a gives me the below settings: Darwin dinesh-bhats-power-mac-g4.local 8.7.0 Darwin Kernel Version 8.7.0: Fri May 26 15:20:53 PDT 2006; root:xnu-792.6.76.obj~1/RELEASE_PPC Power Macintosh powerpc This email sent to site_archiver(a)lists.apple.com
