WinDbg常用命令系列---查看线程调用栈命令K*简介

Windbg里的K*命令显示给定线程的堆栈帧以及相关信息，对于我们调试时，进行调用栈回溯有很大的帮助。

一、K*命令使用方式

在不同平台上，K*命令的使用组合如下

User-Mode, x86 Processor

[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = BasePtr [FrameCount]
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = BasePtrStackPtrInstructionPtr
[~Thread] kd [WordCount]

Kernel-Mode, x86 Processor

[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrFrameCount
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = BasePtrStackPtrInstructionPtr
[Processor] kd [WordCount]

User-Mode, x64 Processor

[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrFrameCount
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrInstructionPtrFrameCount
[~Thread] kd [WordCount]

Kernel-Mode, x64 Processor

[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrFrameCount
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrInstructionPtrFrameCount
[Processor] kd [WordCount]

User-Mode, ARM Processor

[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrFrameCount
[~Thread] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrInstructionPtrFrameCount
[~Thread] kd [WordCount]

Kernel-Mode, ARM Processor

[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] [FrameCount]
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrFrameCount
[Processor] k[b|p|P|v] [c] [n] [f] [L] [M] = StackPtrInstructionPtrFrameCount
[Processor] kd [WordCount]

二、参数说明

  • Thread
    指定要显示其堆栈的线程。如果省略此参数，将显示当前线程的堆栈。只能在用户模式下指定线程。
  • Processor
    指定要显示其堆栈的处理器。
  • b
    显示传递给堆栈跟踪中每个函数的前三个参数。
  • c
    显示干净的堆栈跟踪。每个显示行只包括模块名和函数名.
  • p
    显示在堆栈跟踪中调用的每个函数的所有参数。参数列表包括每个参数的数据类型、名称和值。p选项区分大小写。此参数需要完整的符号信息
  • P
    显示在堆栈跟踪中调用的每个函数的所有参数，如p参数。但是，对于P，功能参数打印在显示屏的第二行，而不是与其余数据打印在同一行上
  • v
    显示帧指针省略（FPO）信息。在基于x86的处理器上，显示还包括调用约定信息
  • n
    显示帧编号。
  • f
    显示相邻帧之间的距离。此距离是实际堆栈上分隔帧的字节数。
  • L
    隐藏显示中的源行。L区分大小写。
  • M
    使用调试器标记语言显示输出。显示器中的每个帧编号都是一个链接，您可以单击它来设置本地上下文并显示本地变量
  • FrameCount
    指定要显示的堆栈帧数。您应该以十六进制格式指定这个数字，除非您使用n（set number base）命令更改了基数。默认值为20（0x14），除非使用.kframes（设置堆栈长度）命令更改了默认值。
  • BasePtr

指定堆栈跟踪的基指针。只有在命令后有等号（=）时，baseptr参数才可用

  • StackPtr
    指定堆栈跟踪的堆栈指针。如果省略stackptr和instructionptr，则该命令使用rsp（或esp）寄存器指定的堆栈指针和rip（或eip）寄存器指定的指令指针。
  • InstructionPtr
    指定堆栈跟踪的指令指针。如果省略stackptr和instructionptr，则该命令使用rsp（或esp）寄存器指定的堆栈指针和rip（或eip）寄存器指定的指令指针。
  • WordCount
    指定要转储的堆栈中的双字指针值的数目。默认值为20（0x14），除非使用.kframes（设置堆栈长度）命令更改默认值。

 三、使用环境

 

Modes

五、几点说明

  1. 发出k、kb、kp、kp或kv命令时，将以表格格式显示堆栈跟踪。如果启用了测线加载，则还会显示源模块和测线号。
  2. 堆栈跟踪包括堆栈帧的基指针、返回地址和函数名。
  3. 如果使用kp或kp命令，将显示在堆栈跟踪中调用的每个函数的完整参数。参数列表包括每个参数的数据类型、名称和值。
  4.  这个命令可能很慢。例如，当MyFunction1调用MyFunction2时，调试器必须具有MyFunction1的完整符号信息，才能显示此调用中传递的参数。此命令不能完全显示未在公共符号中公开的内部Microsoft Windows例程。
  5. 如果使用kb或kv命令，将显示传递给每个函数的前三个参数。如果使用kv命令，还会显示fpo数据，在基于x86的处理器上，kv命令还显示调用约定信息，当使用kv命令时，fpo信息将按以下格式添加到行的末尾。
    FPO textMeaning
    FPO: [non-Fpo]

    No FPO data for the frame.
    FPO: [N1,N2,N3]

    N1 is the total number of parameters.

    N2 is the number of DWORD values for the local variables.

    N3 is the number of registers that are saved.
    FPO: [N1,N2] TrapFrame @ Address

    N1 is the total number of parameters.

    N2 is the number of DWORD values for the locals.

    Address is the address of the trap frame.
    FPO: TaskGate Segment:0

    Segment is the segment selector for the task gate.
    FPO: [EBP 0xBase]

    Base is the base pointer for the frame.

  6. kd命令显示原始堆栈数据。每个双字值显示在单独的行上。将显示这些行的符号信息以及相关符号。此格式创建的列表比其他k*命令更详细。kd命令相当于使用堆栈地址作为参数的dds（显示内存）命令
  7. 如果在函数开头使用k命令（在函数prolog执行之前），则会收到不正确的结果。调试器使用帧寄存器来计算当前的回溯，在函数的prolog被执行之前，这个寄存器没有正确设置
  8. 在用户模式下，堆栈跟踪基于当前线程的堆栈。在内核模式下，堆栈跟踪基于当前寄存器上下文。可以设置寄存器上下文以匹配特定线程、上下文记录或陷阱帧
