我在关注这篇文章

我正在试图理解其中一堆打印出来的信息，这些信息占用了大量内存

我可以理解大多数专栏，但在我的windbg上，我看到了另外一个专栏。我的大多数条目都标记为内部。我不知道那是什么意思。我已经完成了

！gflags+ust

。因此，我可以看到进行内存分配的调用堆栈。除了标记为Internal的条目外，我可以对大多数条目执行此操作

内部是什么意思？这是否与LFH的实施有关？如果这是LFH的内部实现，那么这些内部堆条目将如何以及何时返回到空闲列表？现在它无缘无故地挡住了我的记忆

通过检查内部堆条目中的内存内容，我终于找到了导致泄漏的地方。它包含由相同的
运算符new
引起的大量内存分配。我不知道为什么它们都合并到一个堆条目中，但通过查看内容，我设法找到了导致泄漏的代码。也许，将所有相似的数据合并到一个堆条目是CRT的一个特性？还是我完全误解了堆条目的含义？
TL；DR：标记为“内部”的堆块在\u Heap\u ENTRY.Flags中有一个特殊标志
[编辑]用正确的答案修改了我以前的答案

这是我对你的问题的猜测
根据windbg帮助，“堆”命令代码位于exts.dll（即.\winxp\exts.dll）中
将此DLL放在IDA上并为其下载符号。在DLL中，DumpHeapEntry（）函数中只出现一次“Internal”：

.text:0192463D movzx eax, byte_1963152 .text:01924644 test eax, eax .text:01924646 jz short loc_1924656 .text:01924648 push offset aInternal ; " Internal " .text:0192464D call _ExtensionApis.lpOutputRoutine ; some sort of printf routine
因此，“内部”的输出由字节_1963152的值调节：如果字节_1963152不是0，则打印“内部”。只有一次写入值与0以外的值同时出现（在DumpHeapEntry（）开头调用的ReadHeapEntry（）中）：
这意味着：

if((UINT)var_B & 8) byte_1963152 = 1;
var_B在此处设置：

text:0191EFF7 mov eax, [ebp+var_18] .text:0191EFFA mov edx, [ebp+var_14] .text:0191EFFD mov cl, 10h ; shift right by 0x10 bits .text:0191EFFF call __aullshr .text:0191F004 mov [ebp+var_B], al

.text:0191EF01 push 0 .text:0191EF03 push offset aAgregatecode ; "AgregateCode" .text:0191EF08 push 0 .text:0191EF0A push 0 .text:0191EF0C call _GetShortField@16 ; GetShortField(x,x,x,x) .text:0191EF11 mov [ebp+var_18], eax ; high part .text:0191EF14 mov [ebp+var_14], edx ; low part ; cut .text:0191EF28 mov ecx, [ebp+var_18] .text:0191EF2B and ecx, _EncodeFlagMask ; from HEAP.EncodeFlagMask .text:0191EF31 jz short loc_191EF75 .text:0191EF33 mov edx, [ebp+var_18] .text:0191EF36 xor edx, _CrtHeapCode ; from HEAP.Encoding.Code1 .text:0191EF3C mov eax, [ebp+var_14] .text:0191EF3F xor eax, dword_1963194 ; from HEAP.Encoding.Code2 .text:0191EF45 mov [ebp+var_18], edx .text:0191EF48 mov [ebp+var_14], eax
__aullshr代表“算术无符号长右移”。在上面的代码中，eax是64位无符号long-long的低32位部分，而edx是高32位部分。请注意，var_B是一个8位的量（“使用al”寄存器）
因此：

// where var_14_18 is a combination (64-bit) of var_14 and var_18 var_B = (char)(var_14_18 >> 0x10 );
var_14和var_18在此处设置：

text:0191EFF7 mov eax, [ebp+var_18] .text:0191EFFA mov edx, [ebp+var_14] .text:0191EFFD mov cl, 10h ; shift right by 0x10 bits .text:0191EFFF call __aullshr .text:0191F004 mov [ebp+var_B], al

.text:0191EF01 push 0 .text:0191EF03 push offset aAgregatecode ; "AgregateCode" .text:0191EF08 push 0 .text:0191EF0A push 0 .text:0191EF0C call _GetShortField@16 ; GetShortField(x,x,x,x) .text:0191EF11 mov [ebp+var_18], eax ; high part .text:0191EF14 mov [ebp+var_14], edx ; low part ; cut .text:0191EF28 mov ecx, [ebp+var_18] .text:0191EF2B and ecx, _EncodeFlagMask ; from HEAP.EncodeFlagMask .text:0191EF31 jz short loc_191EF75 .text:0191EF33 mov edx, [ebp+var_18] .text:0191EF36 xor edx, _CrtHeapCode ; from HEAP.Encoding.Code1 .text:0191EF3C mov eax, [ebp+var_14] .text:0191EF3F xor eax, dword_1963194 ; from HEAP.Encoding.Code2 .text:0191EF45 mov [ebp+var_18], edx .text:0191EF48 mov [ebp+var_14], eax
因此，windbg在“AgregateCode”上使用GetShortField（）函数，并设置上述两个变量（也是一个无符号长值）。请注意，它还使用HEAP.Encoding.Code1和HEAP.Encoding.Code2对这两个值进行异或运算（HEAP是当前堆的一部分，堆条目是其中的一部分）
“AgregateCode”是一个包含HEAP_条目和HEAP_FREE_条目结构的字段（来自Win 8.1 x86）：
将其转换为C，给出：

typedef struct _HEAP_ENTRY // 20 elements, 0x8 bytes (sizeof) { union // 6 elements, 0x8 bytes (sizeof) { struct // 3 elements, 0x8 bytes (sizeof) { /*0x000*/ UINT16 Size; /*0x002*/ UINT8 Flags; /*0x003*/ UINT8 SmallTagIndex; /*0x004*/ UINT8 _PADDING0_[0x4]; }; struct // 4 elements, 0x8 bytes (sizeof) { /*0x000*/ ULONG32 SubSegmentCode; /*0x004*/ UINT16 PreviousSize; union // 2 elements, 0x1 bytes (sizeof) { /*0x006*/ UINT8 SegmentOffset; /*0x006*/ UINT8 LFHFlags; }; /*0x007*/ UINT8 UnusedBytes; }; struct // 2 elements, 0x8 bytes (sizeof) { /*0x000*/ UINT16 FunctionIndex; /*0x002*/ UINT16 ContextValue; /*0x004*/ UINT8 _PADDING1_[0x4]; }; struct // 4 elements, 0x8 bytes (sizeof) { /*0x000*/ ULONG32 InterceptorValue; /*0x004*/ UINT16 UnusedBytesLength; /*0x006*/ UINT8 EntryOffset; /*0x007*/ UINT8 ExtendedBlockSignature; }; struct // 2 elements, 0x8 bytes (sizeof) { /*0x000*/ ULONG32 Code1; union // 2 elements, 0x4 bytes (sizeof) { struct // 3 elements, 0x4 bytes (sizeof) { /*0x004*/ UINT16 Code2; /*0x006*/ UINT8 Code3; /*0x007*/ UINT8 Code4; }; /*0x004*/ ULONG32 Code234; }; }; /*0x000*/ UINT64 AgregateCode; }; }HEAP_ENTRY, *PHEAP_ENTRY;
因此，我们有以下伪代码（减去一些其他检查）：
鉴于“AgregateCode”是。。。代码1到代码4的总和：

struct // 2 elements, 0x8 bytes (sizeof) { /*0x000*/ ULONG32 Code1; union // 2 elements, 0x4 bytes (sizeof) { struct // 3 elements, 0x4 bytes (sizeof) { /*0x004*/ UINT16 Code2; /*0x006*/ UINT8 Code3; /*0x007*/ UINT8 Code4; }; /*0x004*/ ULONG32 Code234; }; }; /*0x000*/ UINT64 AgregateCode;
如果将0x10和8移位到AgregateCode字段，则最终将测试Code1的第11位（从0开始计数）
由于结构是一个大的联合体，您最终将测试：\u HEAP\u ENTRY.Flags
碰巧堆标志的值已经是8，它的名称是：heap\u ENTRY\u VIRTUAL\u ALLOC

这个标志似乎用于管理大的分配，尽管这些块由系统内部使用，而不是直接提供给最终用户
通常，此类内部块的标志成员设置为9:HEAP_ENTRY_VIRTUAL_ALLOC|HEAP_ENTRY_BUSY
[编辑]示例：
假设我有一个0x005b0000的堆：

0:004> !heap -h Index Address Name Debugging options enabled 1: 005b0000
此堆（_heap）在0x005b8d00处有一个标记为“Internal”的heap_条目：

0:004> !heap -h 005b0000 Index Address Name Debugging options enabled 1: 005b0000 Segment at 005b0000 to 006b0000 (0009d000 bytes committed) Flags: 00000002 ForceFlags: 00000000 Granularity: 8 bytes Segment Reserve: 00100000 Segment Commit: 00002000 DeCommit Block Thres: 00000800 DeCommit Total Thres: 00002000 Total Free Size: 00001ae8 Max.

堆结构的详细视图（请注意偏移量0x50处的“Encoding”结构（_HEAP_ENTRY），它有助于使用XOR对编码的堆条目进行解码）：
现在是注释代码：
1）获取聚合表单堆\u项
2）使用HEAP.Encoding成员解码（XOR）HEAP\u项
3） Shift result以获取\u HEAP\u条目。标志
4）并使用HEAP\u ENTRY\u VIRTUAL\u ALLOC（8）生成结果，以查看它是否是内部块
