           Summary: Nexon Atlantica Online: broken launcher/updater
                    reports 'Atlantica is currently under maintenance.
                    Please try again later' (relies on 'wininet' to
                    initialize sockets API)
           Product: Wine
           Version: 1.7.21
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal

Hello folks,

split this off from bug 22479

An up-to-date client is need for successful login which in turn can only be
updated by using the launcher 'AtlanticaRun.exe'.

Some "genius" decided to call this API without prior 'WSAStartup'.

MSDN:
http://msdn.microsoft.com/en-us/library/windows/desktop/ms738524%28v=vs.85%29.aspx

--- quote ---
Return value

If no error occurs, gethostbyname returns a pointer to the hostent structure
described above. Otherwise, it returns a null pointer and a specific error
number can be retrieved by calling WSAGetLastError.
Error code    Meaning

WSANOTINITIALISED

A successful WSAStartup call must occur before using this function.

It gets better ... there is no 'WSAStartup' import at all.

Dumping 'AtlanticaRun.exe' imports table reveals:

(I added descriptions for ordinal-only)

What most likely happens is that the stupid code relies on 'wininet' to
initialize sockets API (remains mapped the whole time).

There is an early 'wininet' API call before trying auth server/explicit Windows
sockets API:

--- snip ---
...
0024:Ret  PE DLL (proc=0x7de7e038,module=0x7de40000
L"wininet.dll",reason=PROCESS_ATTACH,res=0x1) retval=1
0024:Starting process L"C:\\Nexon\\Atlantica\\AtlanticaRun.exe"

...
0024:Call wininet.InternetOpenW(00502c90

...
0024:Ret  wininet.InternetOpenW() retval=00000001 ret=004351c0
...
--- snip ---

'winetricks -q wininet' works around.

Unlike the Wine builtin which uses BSD sockets API directly, native binds to
'ws2_32' and calls 'WSAStartup' from 'InternetOpen' to initialize sockets API.

It should be ok to duplicate Windows at least for the part of having
'WSAStartup' called from 'InternetOpenW' and tearing it down with
'InternetCloseHandle'.
Using 'DllMain' function for that would be bad idea and even MS advises against
it.
