Kernel Symbols

iOS's XNU is largely stripped, and contains fewer and fewer symbols with its newer versions. Whereas in pre 3.0 most symbols were visible, nowadays only symbols required for KExt linkage remain so.

This page is started in the hopes of bringing together efforts of the various jailbreakers so as to pool already symbolified sections of the kernel. Because addresses change along with the different builds, please add the symbols under the right kernel version (i.e. release + device). If not 100% sure about a symbol, indicate the level of confidence.

Started with iPod touch 4G, because this is the main kernel the author has largely (>80%) symbolicated. Please add your own. Even if your build is different, the address space doesn't change that much. As of iOS 6 ASLR will shift these symbols by a given offset.

The table below is obsolete - The Joker tool from http://NewOSXBook.com/tools/joker.html exists for the sole purpose of auto-symbolicating kernels, and works on all kernels through XNU 32xx, and symbolicates the symbols below, as well as MIG tables and various other important functions.

Note: For most of the above symbols, a fairly decent source code can be obtained from the public open source XNU available here. Bear in mind that ml_, PE_ and other machine specific functions will naturally be implemented quite differently. (but, it's a start!).
