当你遇到“kernel symbols are wrong. please fix symbols to do analysis.”这样的错误时,这通常意味着你在进行系统级分析,如使用调试器或性能分析工具时,系统内核的符号信息(symbols)与当前运行的内核版本不匹配或已损坏。以下是根据你的提示,分点回答如何修复此问题的方法: 1. 确认kernel symbols的具体问题 首先...

as some kernel symbols are only accessible if you have declared your kernel module as being licensed under the GPL license. To declare it you only need to add a single line at the end of your kernel module code[4]:
[92BABD94-80A4-3F6D-857A-3240E4DA8009]@0xfffffe001203bfd0->0xfffffe00120533ab I am using a debug build of my kext, so the DWARF symbols are part of the binary. I use this line to load the symbols into the lldb session: (lldb) addkext -F /Library/Extensions/KextName.kext/...

This option makes sure that all symbols are loaded into the kernel image (i.e., symbols from all sections) in cost of increased kernel size (depending on the kernel configuration, it may be 300KiB or something like this). Say N unless you really need all symbols. config KALLSYMS...
sections whose starting address is randomized in a specific area. kaslr can thus prevent inserting and redirecting the execution of the kernel to a malicious code if this code relies on knowing where symbols of interest are located in the kernel address space. memory management kaslr sectio...
Depending on the complexity of the structures involved, this can be more or less complicated and we may need many kernel symbols to successfully complete it. A somewhat similar principle applies to locks, which can be re-created/emulated to bypass a locked critical section. Again, the ...
There are two common causes of a double fault: The first cause is a kernel stack overflow. This overflow occurs when a guard page is hit, and the kernel tries to push a trap frame. Because there's no stack left, a stack overflow results, causing the double fault. If you think this ...
