| |
Hello. I can't solve problem that happens while I'm making my kernel module.
part of my module: // ... #include <linux/sched.h> //.... static u32 task_syscall_entry(enum utrace_resume_action action, struct utrace_engine *engine, struct task_struct *task, struct pt_regs *regs){ // ... show_regs(regs);
} But, while making I get:
WARNING: "show_regs" [/home/tehhi/module/trace.ko] undefined!
extern void show_regs(struct pt_regs *); define in header linux/sched.h, place of source code is linux/arch/x86/kernel/process_32.c It use extern void __show_regs(struct pt_regs *); and extern asmlinkage void __backtrace(void); I think that extern means that I can use it (and there are no static symbols in this function).
When trying to insert module, it predictably complains of an unknown symbol show_regs.
What am I missing here?
