Windows软件调试初探-进程与线程

进程资源

每个进程都有这些资源：

  • 一个虚拟地址空间。
  • 全局唯一Cid，即PID。
  • 一个可执行映像，即该进程可执行文件在内存中的表示。
  • 一个或多个线程。
  • 一个内核空间中的EPROCESS。
  • 一个内核空间中的对象句柄表。
  • 一个用于描述内存目录表起始位置的基地址，即页目录基地址DirBase。当CPU切换到该进程时，将该地址加载到页表基地址寄存器如CR3或TTBR，再由RVA翻译为正确物理地址。
  • 一个用户空间中的PEB。
  • 一个访问令牌。

例如列出系统所有进程：

DirBase的高20位为该进程页目录的页帧编号PFN，低12位含义因CR4的PCIDE位第17位不同。PCIDE位1时CPU缓存多个进程页表信息，低12位为进程上下文ID。为应对CPU的Meltdown和Spectry漏洞，NT内核引入KVA影子安全补丁，启用PCIDE功能。

例如：启用了KVA影子，使用模式1，该模式要求PCID功能支持。

也可以用!peb命令观察某地址处PEB结构。

内核模式和用户模式

例如Win32应用程序中调用Kernel32.dll导出的Kernel32!ReadFile后堆参数进行检查，再调用Ntdll!NtReadFile。Ntdll!NtReadFile将系统服务号，如0xa1等放入RAX，参数指针放入EDX，用int 2e发出调用。用!idt 2e看到2e号向量对应服务例程是Nt!KiSystemService，即内核态中用来分发系统调用的例程，在NtOsKrnl.exe中。Nt!KiSystemService进行权限检查和准备内核栈，根据系统服务分发表SSDT查找要调用的服务函数NtReadFile地址和参数描述。KiSystemService通过iret将执行权返回NtDll!NtReadFile。

};
__int64 NtReadFile() {
    __int64 result; // rax
    result = 6LL;
    if ((MEMORY[0x7FFE0308] & 1) != 0)
        __asm { int     2Eh; DOS 2 + internal - EXECUTE COMMAND }

};

从奔腾Ⅱ开始，在Windows XP或Windows Server 2003及以上在启动时检测是否支持快速系统调用命令。IA-32的奔腾Ⅱ引入sysenter/sysexit，AMD K7引入syscall/sysreturn。当支持快速系统调用时，系统启动时在全局描述表GDT中建立4个段描述符，依次排列为sysenter进入内核模式时使用的代码段CS和栈段SS，以及sysexit从内核模式返回用户模式使用的代码段和栈段。然后设置下表所示MSR，SYSENTER_EIP_MSR为sysenter要跳转到的目标例程Nt!KiFastCallEntry，SYSENTER_CS_MSR为Nt!KiFastCallEntry所在代码段KGDT_R0_CODE，SYSENTER_ESP_MSR为新栈指针即SYSENTER_CS_MSR+8。最后将SystemCallStub代码片段复制到SharedUserData内存区，该内存区将被映射到每个Win32进程空间中，每次快速系统调用时NTDLL.DLL中残根stub函数调用SystemCallStub代码片段。

MSR名称 MSR地址 用途
SYSENTER_CS_MSR 174h 目标代码段CS选择子
SYSENTER_ESP_MSR 175h 目标ESP
SYSENTER_EIP_MSR 176h 目标EIP

每个系统MSR都不同，例如：

1
rdmsr 174

快速系统调用模式切换总结为：

发起系统调用 入口内核例程 返回 返回内核例程
int 2e KiSystemService iret KiSystemCallExit
sysenter KiFastCallEntry sysexit KiSystemCallExit2
syscall KiFastCallEntry sysret KiSystemCallExit3

IA-32下快速系统调用实例ReadFile：Win32程序用Kernel32!ReadFile()调用NtDll!NtReadFile()，转到SharedUserData!SystemCallStub用sysenter进入nt!KiFastCallEntry，通过Nt!KiSystemService调用Nt!NtReadFile。返回时Nt!KiSystemService通过Nt!KiSystemCallExit2用sysexit退出内核模式回到SharedUserData!SystemCallStub。

内核模式也可主动调用用户模式例程，称为逆向调用。由Nt!KiCallUserMode发起调用，进入用户模式执行NtDll!KiUserCallbackDispatcher。用户模式完成后执行int 2b返回动作，对应Nt!KiCallbackReturn。

上述State状态有：

状态 值 含义 可转换到的状态
Initialized 0 正在创建和初始化 DeferredReady
Ready 1 就绪，可被分发调度运行 Running
Running 2 正在某个CPU上运行 Waiting、Terminated
Standby 3 待命，即下一个要执行的线程 Running、DeferredReady、被抢先Preempt
Terminated 4 结束执行
Waiting 5 等待，如睡眠函数、取消息函数、等待同步对象等，主动放弃执行机会 Transition、DeferredReady、Running
Transition 6 过渡状态，线程已可以运行但内核栈被交换出内存，交换回后进入Standby DeferredReady
DeferredReady 7 延迟就绪，为缩短扫描调度数据库加锁时间，内核把就绪线程设置为次状态 Ready
Gate Wait 8 门状态，等待门分发器对象时进入

上述WaitReason为KWAIT_REASON枚举类型，常见如下：

WoW进程

x86与x64运行模式转化（用户层）：

1
2
3

~ //当前进程所有线程
~0s //转到0号线程上下文
.effmach amd64 //转为x64运行模式 栈帧回溯将出现wow64、wow64cpu、wow64win等转接层DLL
.effmach x86 //切换为32位模式

在x86模式下查看栈帧时，能看到俩ntdll模块，一个64位一个32位，32位的加上基地址后缀如“ntdll_77700000”。WoW进程中每个进程俩PEB，每个线程俩TEB，俩栈，如：

!wow64exts.info

其中Guest指x86，Native指x64。在32位NTDLL.DLL中如NtReadFile跳转WoW64SystemServiceCall，进入wow64cpu!KiFastSystemCall，跳转33号段选择子，即32位兼容模式过度64位模式方法。

系统对WoW进程注册表访问实施注册表重定向，如”HKEY_LOCAL_MACHINE\Software”重定向到“HKEY_LOACL_MACHINE\Software\Wow6432Node”等。一些COM组件有关等表键修改时同时修改32位和64位表键，这叫“注册表反射”。WoW进程访问系统文件目录时被自动重定向到SysWOW64或SysArm32目录中，这叫文件系统重定向。

最小进程是一类并列于NT进程的特殊进程，只需创建进程时指定一个特殊标志，但资料有限未完全研究清楚。该进程只创建进程空间，不自动想进程空间中添加内容。目前只有内存压缩技术、基于虚拟化的安全VBS和注册表进程Registry使用了最小进程。当某进程的EPROCESS结构的Flags字段的Flags3为1表示该进程为最小进程。内存压缩技术打开方式如下，有MemCompression进程创建。内存压缩进程在任务管理器中不显示。

Registry进程有3个线程，两个线程入口函数为CmpLazyWriteWorker用于把修改过的注册表数据成批写回硬盘工作线程。另一个线程叫CmpDummyThreadRoutine，启动后等待CmpDummpyThreadEvent事件，等待成功则用KeBugCheckEx触发蓝屏崩溃，其用途为占位，不让内存管理器把它内存页交换出去。Registry进程在任务管理器中有时显示。

Pico进程时最小进程一个子类，但运行时并列于NT进程和最小进程，与NT内核之间交互需要PICO提供器，如WSL子系统核心驱动LXCORE。

在WSL启动早期，LXCORE用nt!PsRegisterPicoProvider注册Pico提供器，它有俩参数为结构指针，第一个字段表示大小，后面是LXCORE提供给内核的回调函数。如Pico进程执行系统调用时，NT内核逆向调用LXCORE!PicoSystemCallDispatch转交给LXCORE继续分发处理。当Pico进程内发生错误时，NT内核nt!KiDispatchException逆向调用LXCORE!PicoDispatchException。注册成功后NT内核也返回一个类似结构供Pico提供器调用。

WSL中每个Linux进程都是一个Pico进程，EPROCESS显示为System Process，该结构Flags2的第10位PicoCreated标志位为，PicoContext字段指向Pico提供器使用的Pico上下文结构。
