Should I call for a VOTE, or is it OK having a top level module for all Win32 related pieces? Please, comment. Thank you in advance. -- :Emanuele Aliberti

crash in usetup if an allocation size is given for a call to NtCreateFile

by Hartmut Birr

Hi, I've done some little changes in usetup for optimisation. One thing is the decompressing of files from a cabinet container. If the destination file exist, it is created with the create disposition FILE_OVERWRITE and without a pointer to the allocation size. If I add an allocation size pointer (cabinet.c.diff), usetup does crash after copying of all files and creating the registry. (ntoskrnl\ke\exception.c:94) KiRaiseException (ntoskrnl\ke\i386\exp.c:1306) Unhandled UserMode exception, terminating thread Exception: -1160049408(0) Processor: 0 CS:EIP 1b:12000 ????? cr2 66f924 cr3 56a000 Proc: 8094a1f0 Pid: 5c <smss.exe> Thrd: 80954088 Tid: 60 DS 23 ES 23 FS 3b GS 0 EAX: 00012000 EBX: 00000001 ECX: 0066fc18 EDX: 7c90a479 EBP: 0066ff54 ESI: 00000004 ESP: 807ebd64 EDI: 0066fc28 EFLAGS: 00000216 Frames: <smss.exe:741b> subsys/system/usetup/console.c:660 <smss.exe:19c41> subsys/system/usetup/usetup.c:3321 <smss.exe:1a65e> subsys/system/usetup/usetup.c:3781 <0> The address of the crash has nothing to do with the decompressing of the install files. If I change IoCreateFile file a little bit, that the allocation size pointer isn't read (file.c.diff), usetup didn't crash.

RE: 18273: create some start menu entries for notepad, regedit and winefile

by Ge van Geldorp

> From: mf(a)svn.reactos.com > > create some start menu entries for notepad, regedit and winefile Do we really need/want the winefile link on the desktop? Especially since it is also present in the start menu now. If I recall correctly, the Command Prompt was put on the desktop 'cause at the time it was the only viable way to start programs, I think maybe even the Command Prompt link could go from the desktop now.

some thoughts

by D. Hazelton

I've been thinking about a chat I had with Alex Ionescu about the "userspace driver framework" that MS has put in Windows Vista for a couple of days now. Mostly I was trying to think of how they could create a secure system where the drivers could live outside the kernel and still manage to do the job of providing clean access to the hardware. I was doing this because I am just starting to take a look at the ReactOS code with an eye towards helping on the project. That being the case I decided to see if I could find a spot where I could fit my skills into the project. While I'm more geared towards fixing bugs or filling out places marked "TODO" the thought of userspace drivers - or rather, just the thought that such a system would allow for drivers that could die and not take the system with them - has caught my interest. At the current time the only way I can see this being done is by using the HAL to abstract all hardware and providing an API that, via the HAL, will allow for _AUTHENTICATED_ programs (aka drivers) to register themselves with the kernel and provide access to said devices. The access itself would best be handled by the drivers registering an interface that programs can use to call directly into the driver. This just leaves me with a simple problem to solve - should the interface be a COM/COM+ interface (or it's primitive, since I don't think anyone wants the lag having COM/COM+ in the kernel would cause) or should it be something simpler, like a UFS path ? DRH (if the PGP signature looks bad, the list probably modified the mail)
