C++ (Cpp) segv Examples

Example #1

File: trap.c Project: liuyang201666/linux-akae

void segv_handler(int sig, struct uml_pt_regs *regs)
{
    struct faultinfo * fi = UPT_FAULTINFO(regs);

    if (UPT_IS_USER(regs) && !SEGV_IS_FIXABLE(fi)) {
        bad_segv(*fi, UPT_IP(regs));
        return;
    }
    segv(*fi, UPT_IP(regs), UPT_IS_USER(regs), regs);
}

Example #2

File: process.c Project: GodFox/magx_kernel_xpixl

static void handle_segv(int pid)
{
	struct ptrace_faultinfo fault;
	int err;

	err = ptrace(PTRACE_FAULTINFO, pid, 0, &fault);
	if(err)
		panic("handle_segv - PTRACE_FAULTINFO failed, errno = %d\n",
		      errno);

	segv(fault.addr, 0, FAULT_WRITE(fault.is_write), 1, NULL);
}
