为什么 lm 命令不显示模块？

Question

我在虚拟机中打开了一个计算器，但是当尝试使用命令 lm 从 windbg 查看它时，它没有显示。

kd> !process 0 0 calc.exe
PROCESS ffffe0000046a080

kd> .process ffffe0000046a080

更改上下文没有帮助，但我不得不尝试一下。我记得把calc列在列表的最前面，但我不知道在什么情况下

kd> lm
start             end                 module name
fffff800`00000000 fffff800`00088000   CI         (deferred)             
fffff800`0008a000 fffff800`000f0000   mcupdate_GenuineIntel   (deferred)             
fffff800`000f0000 fffff800`000fe000   werkernel   (deferred)             
...

Answer 1

要么使用 .process /p /r

或使用
.reload /用户

用于列出您的用户模式模块

kd> !process 0 0 calc.exe
PROCESS 865a3030  SessionId: 1  Cid: 0fe4    Peb: 7ffda000  ParentCid: 0850
    DirBase: 7e24a6e0  ObjectTable: c44a2df0  HandleCount:  81.
    Image: calc.exe

kd> .process 865a3030
Implicit process is now 865a3030
kd> lm m calc*
Browse full module list
start    end        module name

kd> .reload /user
Loading User Symbols

kd> lm m calc*
Browse full module list
start    end        module name
00e00000 00ec0000   calc       (deferred)

或

kd> !process 0 0 calc.exe
PROCESS 865a3030  SessionId: 1  Cid: 0fe4    Peb: 7ffda000  ParentCid: 0850
    DirBase: 7e24a6e0  ObjectTable: c44a2df0  HandleCount:  81.
    Image: calc.exe

kd> .process 865a3030
Implicit process is now 865a3030
kd> lm m calc*
Browse full module list
start    end        module name


kd> .process /p /r 865a3030
Implicit process is now 865a3030
Loading User Symbols

kd> lm m calc*
Browse full module list
start    end        module name
00e00000 00ec0000   calc       (deferred)

按照blabb所说的去做后，它确实显示了它，实际上不仅列出了内核内存（fffff8 ...）而且还列出了用户内存（00007 ..）。

kd> lm
start             end                 module name
00007ff7`35260000 00007ff7`35346000   calc       (deferred)             
00007ffa`f7500000 00007ffa`f7563000   oleacc     (deferred)             
[...]       
00007ffa`fcbe0000 00007ffa`fcd89000   ntdll      (deferred)             
fffff800`00000000 fffff800`0005f000   volmgrx    (deferred)             
[...]     
fffff800`000dd000 fffff800`0013f000   CLFS       (deferred)
