Well I was the one that asked Jake if he could provide a system for patching static functions in the kernel. If you search the archives there is a patch for doing this. It's actually quite reasonable to patch code out from under a running system. One can replace the entry opcode of the function with a jump to the patched code. The only time this becomes a problem is when structures change, however backporting the fix shouldn't be a problem. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] Represent yourself, show up at BABUG http://www.babug.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
