卷的句柄信息
Handle Information for Volume
我使用WinDBG获取句柄信息:
kd> !handle 430
PROCESS 85c91030 SessionId: 0 Cid: 0388 Peb: 7ffdc000 ParentCid: 01e8
DirBase: 7ee841c0 ObjectTable: 8da023f0 HandleCount: 539.

Handle table at 9a3da000 with 539 entries in use
0430: Object: 8480e038 GrantedAccess: 00100080 Entry: 8da01860

ObjectHeader: 8480e020 (new version)
HandleCount: 1 PointerCount: 2
Directory Object: 00000000 Name: \ {HarddiskVolume2}
我知道大部分数据来自_FILE_OBJECT,但我不知道{HarddiskVolume2} 是如何确定的。 WinDBG 如何获得这些信息?

如果您使用的是 xp-sp3,此脚本可以帮助您了解 windbg 如何检索 {hardiskvolume1} 此脚本还假设某些事情,例如 kernel_handle_table 级别不要盲目索引 handle * size + start of table
在后面的os中OBJECT_HEADER结构不同没有NameInfoOffset
字段
在 OBJECT_HEADER
结构中,但 TypeIndex
您可能需要
修改此脚本以适应 os > xp
