User Login, etc.
by Richard Campbell 30 Sep '04

30 Sep '04

Well, As Royce pointed out to me yesterday, it appears that the user profile is created the first time the user logs on...and the registry entries are set up. My question is how should this be handled in ROS? In WINLOGON? Does anyone have any documentation on the windows logon procedure available? Richard

Wizard Edit box Bug
by Alex Ionescu 30 Sep '04

30 Sep '04

Hi, This is especially in regard to Steven, since he mentionned it might be a WINE bug. I had mentionned that the Edit Box cursor/text isn't always centered...and I finally managed to get a good picture, attached below. I agree this is a trivial bug but I'm just posting it for all to see and so that Steven can possibly put it on WINE's bug list (if it's indeed a WINE bug) Best regards, Alex Ionescu

Page protection ldr change breaks VMware SVGA driver

With current CVS, the VMware SVGA driver crashes. It happens in a HwFindAdapter() call. While tracing through the driver, I got this eery "I've been here before" feeling. And sure enough, I fixed this same crash about a year and a half ago. The problem is that vmx_svga.sys has a section alignment of 0x20 instead of the normal 0x1000. So, sections are much smaller than the page size. When setting the page protections you need to take into account all the sections which might be mapped to that page. This was implemented in ntoskrnl/ldr/loader.c rev 1.126. Gé van Geldorp.

ASSERT_IRQL and unrelated mm/mdl.c
by art yerkes 29 Sep '04

29 Sep '04

I started putting in ASSERT_IRQL in ntoskrnl, hoping that only my own code would break from it. The results are ... interesting. I've put a metabug (426) on bugzilla which is about reactos not honoring documented irql requirements. I fixed a place in win32k.sys, but there are probably more. I think we should clean these up and get the assert_irqls into HEAD, so that people like me won't get bitten over and over by assuming we're in one irql when we're in another. Unrelated, please take a look at the following patch, anyone who's cozy with the mm. The reason why this code is needed is that MmNotPresentFault and MmAccessFault will try to lock the address space as well as MmProbeAndLockPages. Since this is a spin lock, reactos will always bugcheck when MmProbeAndLockPages faults in a page, even if that would be legal otherwise. I'm not sure if this patch fixes it right but it does seem to work this way. If i don't hear too many complaints i'll think about committing something similar. There are a couple of other places where MmNotPresentFault is called (section.c) within a MmLockAddressSpace. Another idea would be to give MmNotPresentFault and MmAccessFault an extra argument so they can ignore locking if the address space is already locked. -- Hey, Adam Smith, keep your invisible hands to yourself!

ReactOS and Cygwin
by WaxDragon 29 Sep '04

Hello! I thought I would try running Cygwin on a ReactOS CVS build, and after talking with some of you on IRC, I went ahead. After setting PATH=c:\cygwin\bin;%PATH%, dd.exe, uniq.exe, bash.exe, and ls.exe all drop ros to the kernel debugger with an exception 14. This is on the now dead Command Prompt: 41 [Main] ? 10 cygheap_user::init: SetTokenInformation (TokenDefaultDacl): Win32 error 1 Here is the debug output leading up to the exection of uniq.exe: (objects/gdiobj.c:401) Can't delete hObj:0x00042d77, type:0x007f0000, flag:0 (objects/gdiobj.c:401) Can't delete hObj:0x00042f72, type:0x007f0000, flag:0 (ntuser/desktop.c:808) RtlQueryRegistryValues failed for PaintDesktopVersion: status=c0000005 (NTDLL:ldr/utils.c:2060) Relocating (10000000 -> 631000) C:\cygwin\bin\cygiconv-2.dll (NTDLL:ldr/utils.c:2060) Relocating (77f00000 -> 941000) C:\ReactOS\system32\KERNEL32.dll (NTDLL:ldr/utils.c:2060) Relocating (77dc0000 -> 9ba000) C:\ReactO(NTDLL:ldr/utils.c:2060) Relocating (61000000 -> 9d0000) C:\cygwin\bin\cygwin1.dll S\system32\advapi32.dll (sec/misc.c:489) GetUserNameA: stub Entered debugger on exception number 14.
