MASM32编程调用 API函数RtlIpv6AddressToString,Windows 10 容易,Windows 7 折腾

一、需求分析

最近用MASM32编程更新SysInfo,增加对IPv6连接信息的收集功能,其中涉及到 MIB_TCP6ROW_OWNER_MODULE 结构体:

;typedef struct _MIB_TCP6ROW_OWNER_MODULE {
;  UCHAR         ucLocalAddr[16];
;  DWORD         dwLocalScopeId;
;  DWORD         dwLocalPort;
;  UCHAR         ucRemoteAddr[16];
;  DWORD         dwRemoteScopeId;
;  DWORD         dwRemotePort;
;  DWORD         dwState;
;  DWORD         dwOwningPid;
;  LARGE_INTEGER liCreateTimestamp;
;  ULONGLONG     OwningModuleInfo[TCPIP_OWNING_MODULE_SIZE];
;} MIB_TCP6ROW_OWNER_MODULE, *PMIB_TCP6ROW_OWNER_MODULE;
 
MIB_TCP6ROW_OWNER_MODULE STRUCT
	ucLocalAddr     UCHAR	16 dup (?) 
	dwLocalScopeId	DWORD	?
	dwLocalPort     DWORD	?
	ucRemoteAddr	UCHAR	16 dup (?)
	dwRemoteScopeId	DWORD	?
	dwRemotePort	DWORD	?
	dwState	        DWORD	?
	dwOwningPid     DWORD	?
	liCreateTimestamp	LARGE_INTEGER <>
	OwningModuleInfo	ULONGLONG	TCPIP_OWNING_MODULE_SIZE dup(?)
MIB_TCP6ROW_OWNER_MODULE ENDS
PMIB_TCP6ROW_OWNER_MODULE typedef ptr MIB_TCP6ROW_OWNER_MODULE
;typedef struct _MIB_TCP6TABLE_OWNER_MODULE {
;  DWORD                    dwNumEntries;
;  MIB_TCP6ROW_OWNER_MODULE table[ANY_SIZE];
;} MIB_TCP6TABLE_OWNER_MODULE, *PMIB_TCP6TABLE_OWNER_MODULE;
 
MIB_TCP6TABLE_OWNER_MODULE STRUCT
	dwNumEntries DWORD	?
    table        MIB_TCP6ROW_OWNER_MODULE ANY_SIZE dup()
MIB_TCP6TABLE_OWNER_MODULE ENDS 
PMIB_TCP6TABLE_OWNER_MODULE typedef ptr MIB_TCP6TABLE_OWNER_MODULE

其中的成员

    ucLocalAddr     UCHAR    16 dup (?) 
    ucRemoteAddr    UCHAR    16 dup (?)

其值是IPv6格式的IP地址,需要转换成字符串。微软官网上提到可以使用API函数RtlIpv6AddressToString()来完成这个转换。

RtlIpv6AddressToString is a convenience function that does not require that the Windows Sockets DLL be loaded to access a function provided in Windows Sockets to perform IP address to string conversion.

RtlIpv6AddressToString 是一个方便的函数,它不需要加载 Windows 套接字 DLL 来访问 Windows 套接字中提供的函数来执行 IP 地址到字符串的转换。

用grep命令搜索了MASM32安装文件夹中includes文件夹中的.inc文件,发现有以下.inc文件包含了RtlIpv6AddressToString函数的声明:

\masm32\include\dnslib.inc

\masm32\include\ntdll.inc

\masm32\include\ntoskrnl.inc

\masm32\include\wdmsec.inc

 二、代码在Windows 10上汇编连接运行正常

编写了调用代码:

include    \masm32\include\ntoskrnl.inc ;RtlIpv6AddressToStringA
includelib \masm32\lib\ntoskrnl.lib

.code

; Get Local Addr ip
mov    esi, pTable
invoke RtlIpv6AddressToString, addr (MIB_TCP6ROW_OWNER_MODULE ptr [esi]).ucLocalAddr, offset g_szBuf128a

代码在使用Windows 10的电脑上汇编、连接、运行正常:

三、代码在Windows 7 上汇编连接成功,运行出错

 但是把生成的EXE程序复制到使用Windows 7的电脑上运行,就出错:

把程序源代码复制到使用Windows 7的电脑上,汇编连接都行,但是运行时仍然出现上面的故障。

四、换文件头测试

那就换个头文件来试试:

(一)dnslib 


include    \masm32\include\dnslib.inc
includelib \masm32\lib\dnslib.lib

在windows 10 和 windows 7上可以顺利完成汇编、连接,但运行时均提示:

 (二)wdmsec

include    \masm32\include\wdmsec.inc
includelib \masm32\lib\wdmsec.lib

在windows 10 和 windows 7上汇编时出错:

***********
ASCII build
***********

----------------------------------------
WARNING Duplicate include file winextra.inc

Assembly Error

请按任意键继续. . .

(三)ntdll

include    \masm32\include\ntdll.inc    ;RtlIpv6AddressToStringA
includelib \masm32\lib\ntdll.lib

 在windows 10 和 windows 7上可以顺利完成汇编、连接和运行。

 在Windows 7中,对网络连接关连进程信息获取和显示得要比Windows 10中完善。

五、跳过头文件,自己GetModuleHandle 和 GetProcAddress 后调用

微软网站也提到:

An application could also use the GetModuleHandle and GetProcAddress functions to retrieve the function pointer from the Ntdll.dll and call this function.

应用程序还可以使用 GetModuleHandle 和 GetProcAddress 函数从 Ntdll 检索函数指针.dll并调用此函数。

相关的代码的代码如下:

        .else
            mov byte ptr g_szBuf128a, 0
        .endif

  ;……其它代码

        ;mov    esi, pTable
        ;invoke RtlIpv6AddressToString, addr (MIB_TCP6ROW_OWNER_MODULE ptr [esi]).ucLocalAddr, offset g_szBuf128b  

        .if g_lpfnRtlIpv6AddressToString != NULL
            mov    esi, pTable        
            invoke g_lpfnRtlIpv6AddressToString, addr (MIB_TCP6ROW_OWNER_MODULE ptr [esi]).ucRemoteAddr, offset g_szBuf128b

        .else
            mov byte ptr g_szBuf128b, 0
        .endif

七、其它问题

RtlIpv6AddressToString函数支持的最低客户端是 Windows Vista,支持的最低服务器 Windows Server 2008,在Windows XP上用不了。
