以下是使用 Python 2 实现上述步骤的代码示例:
```python
import os
import ctypes
from ctypes import *
# 定义常量
PTRACE_ATTACH = 0x10
PTRACE_SETOPTIONS = 0x4200
PTRACE_O_TRACECLONE = 0x00000008
PTRACE_SYSCALL = 12
# 定义结构体和函数原型
class user_regs_struct(Structure):
_fields_ = [
("ebx", c_ulong),
("ecx", c_ulong),
("edx", c_ulong),
("esi", c_ulong),
("edi", c_ulong),
("ebp", c_ulong),
("eax", c_ulong),
("ds", c_ulong),
("es", c_ulong),
("fs", c_ulong),
("gs", c_ulong),
("orig_eax", c_ulong),
("eip", c_ulong),
("cs", c_ulong),
("eflags", c_ulong),
("esp", c_ulong),
("ss", c_ulong),
("ptrace_event", c_ulong),
("oldmask", c_ulong),
("cr2", c_ulong)
]
def attach(pid):
libc = ctypes.cdll.LoadLibrary('libc.so.6')
libc.ptrace(PTRACE_ATTACH, pid, None, None)
os.waitpid(pid, 0)
libc.ptrace(PTRACE_SETOPTIONS, pid, None, PTRACE_O_TRACECLONE)
def get_syscall(pid):
regs = user_regs_struct()
libc = ctypes.cdll.LoadLibrary('libc.so.6')
libc.ptrace(PTRACE_GETREGS, pid, None, byref(regs))
return regs.orig_eax
def continue_exec(pid):
libc = ctypes.cdll.LoadLibrary('libc.so.6')
libc.ptrace(PTRACE_SYSCALL, pid, None, None)
os.waitpid(pid, 0)
# 主函数
if __name__ == '__main__':
parent_pid = 868518
child_pid = 117135
# 挂载子进程到父进程上
attach(parent_pid)
continue_exec(child_pid)
# 等待子进程创建新进程
while True:
continue_exec(child_pid)
if get_syscall(child_pid) == __NR_clone:
break
# 获取新进程的 PID
child2_pid = os.waitpid(child_pid, 0)[0]
# 挂载新进程到父进程上
attach(parent_pid)
continue_exec(child2_pid)
```
需要注意的是,Python 2 和 Python 3 在处理字符串、函数参数等方面存在一些差异,因此在具体实现时需要根据实际情况进行调整。此外,上述代码可能需要以 root 用户身份运行。
