Fix the console properties dialog, when launching and transmitting console properties. Before, the properties dialog was directly launched by the console server (consrv), running with CSRSS (System) privileges, what constituted a security hole. Now, I create a remote thread in the running process owning the console for launching the properties dialog (thus it has only user privileges, and not System ones anymore). For that purpose, I basically took the technique described in the following paper (Cesar Cerrudo, "Story of a dumb patch", http://www.argeniss.com/research/MSBugPaper.pdf or http://www.scn.rain.com/~neighorn/PDF/MSBugPaper.pdf), where basically the console server shares the console properties via a shared memory section with the console properties dialog dll. The address of the thread which launches the dialog in the context of the console app is given to the console server the same way as we do for the control handler (called e.g. when you press Ctrl-C, etc...)
Of course this is quite hackish, because you have the GUI interface split between the console server and the console properties dialog dll. Something far more elegant would be to put all the GUI thingie into a dedicated dll or exe, running with the same privileges as the console program itself (a kind of console -- or terminal -- emulator).
[CONSOLE.DLL]
Fix retriving / setting colors.c and other things.
[CONSRV.DLL]
- Fix retrieving / setting console properties from the registry (via the HKCU\Console\* keys), via the shell shortcuts (not totally done at the moment, because somebody has to implement properly that thing : http://msdn.microsoft.com/en-us/library/windows/desktop/bb773359(v=vs.85).aspx (NT_CONSOLE_PROPS structure stored as a shortcut data block) (at application launching time), and via the console properties dialog.
- Few DPRINTs removed.

Rename functions to their new scheme: ConSrv* instead of Win32Csr* or Conio* (with some exceptions for the latter case).
No code changes.
svn path=/branches/ros-csrss/; revision=58213
- Start to uniformize some helpers' names :
ConioLockConsole --> ConioGetConsole and ConioUnlockConsole --> ConioReleaseConsole
ConioLockInputBuffer --> ConioGetInputBuffer and ConioUnlockInputBuffer --> ConioReleaseInputBuffer
ConioLockScreenBuffer --> ConioGetScreenBuffer and ConioUnlockScreenBuffer --> ConioReleaseScreenBuffer
but the overall naming must be revamped.
- Add them a boolean parameter to determine whether or not we should lock the console. It is useful to not lock an already locked console when input / output waiting threads are called,
because these are called from functions which lock the console.
- In the GUI console window message loop, after retrieving a pointer to the corresponding console, lock it before calling funtions in the message dispatcher (and unlock the console at the end).
- Use PostMessage instead of SendMessage for "sending" GUI messages to console windows, to avoid possible deadlocks (because of console locking).
- Add temporary /// LOCK /// comments to easily localize where I deactivated extra console (un)locking code (this remains to be analyzed further).
svn path=/branches/ros-csrss/; revision=58205
- Isolate the members of the CONSOLE structure which are used as input buffer data, in a new structure called ... CONSOLE_INPUT_BUFFER !
- Rename some helper functions to better match what they are doing.
svn path=/branches/ros-csrss/; revision=58191
Rename some structures (CSRSS_... ---> CONSOLE_...) and clarify what the ConsoleHandle members are for (--> OutputHandle or InputHandle).
No code changes otherwise.
svn path=/branches/ros-csrss/; revision=58119
- Delete all the remnants of Win32CsrValidateBuffer calls, which were replaced by standard CsrValidateMessageBuffer calls, and therefore delete the unused server.c file.
- Adapt WriteConsole API to use CSR waits. This replaces the old event-based waiting.
TODO: Dereference all the waits in Console->WriteWaitQueue.
svn path=/branches/ros-csrss/; revision=57819
- Move console-related Vista+ functions from client/vista.c to a dedicated client/console/vista.c file, and add it to compilation.
- Move some helper functions from console.c to history.c.
- Use the new api index names in history.c.
[CONSRV]
- Merge CSRSS_GET_HISTORY_INFO and PCSRSS_SET_HISTORY_INFO structures declarations into CSRSS_HISTORY_INFO, and therefore use only one member of it inside CONSOLE_API_MESSAGE structure.
- WORD --> UINT for few structure members related to history information.
svn path=/branches/ros-csrss/; revision=57713
- Use the DLL instance for getting its win23 resources.
- Use the CONSOLE_PROCESS_DATA structure (see r57686) for accessing console-specific fields of the processes (instead of using them implemented in the CSR_PROCESS structure).
- Win32CsrDuplicateHandleTable --> ConsoleNewProcess since it's the callback function called when a new process is created, and start to move some hacks currently present in BaseSrvCreateProcess.
TODO: suppress the starting-application-related hacks in BaseSrvCreateProcess (in basesrv).
svn path=/branches/ros-csrss/; revision=57689
- Add consrv to compilation. It compiles now \o/
- Convert the used console-csrss structures to the new ones.
[CSR]
- Continue to move some structures, and temporary activate a symbol.
[WIN32CSR]
- Clean a header.
svn path=/branches/ros-csrss/; revision=57602
- Move all the console subsystem from win32csr to a new server dll called consrv.dll (instead of putting it directly to winsrv.dll). It's because I want to rework on this later on.
Many things must be done in order to achieve the moving (renaming functions, etc...). Tables & symbol names come from http://j00ru.vexillium.org/csrss_list/api_list.html as usual,
but here I took the Win 2k3 ones and I added few Win 7 functions which already existed in our codebase. The other table names are guessed based on what originally existed in csrsrv
and so on. Many stubs are also missing.
Cultural remark: consrv.dll originally existed in Beta releases of Windows NT 3.1 (e.g. the October 1991 one), but was soon merged with winsrv.dll and thus, in subsequent versions of
Windows, the console subsystem is also found in winsrv.dll. See http://www.logotypes.se/NT310CSRSS.txt and http://j00ru.vexillium.org/?p=349#comment-1883. One has to wait until
Windows 7 to see it moving again to conhost.exe.
[CSRSRV]
- Add an explanation comment on what the ValidTable member in the CSR_SERVER_DLL structure is for.
