* Do not use ugly and messy code to create linked stacks and other such resource-wasting steps. Use our newly implemented 60KB stack support and MmGrowKernelStack when needed. * Write all the low-level code in assembly instead of relying on structures and hodgepodge code. * Add debugging/detection features for invalid calls, such as invalid IRQL, APCs being disabled, invalid previous mode detection (this allowed me to fix the KWAIT_BLOCK bug today). * Finally fix the last (I hope) remaning trap frame bug issue related to V86 mode bias. One of the "hacks" in syscall.S has already been removed and I can now do the promised cleanup. * Allow some failulre cases in callbacks (not all implemented) and extend stack space for future use of SEH in the ntdll dispatcher. * Fix win32k to use callbacks properly: the system fills out *Result and *ResultLength, not the caller. * Use SEH (ProbeForWrite) in callbacks to detect invalid user-mode memory. * Save NPX State and ExceptionList across callbacks (I think this wasn't fully properly done in all cases). svn path=/trunk/; revision=20794
======================== ReactOS Version 0.2.x Updated June 23rd, 2004 ======================== 1. What is ReactOS? ReactOS is an Open Source effort to develop a quality operating system that is compatible with Windows NT applications and drivers. The ReactOS project, although currently focused on Windows NT 4.0 compatibility, is always keeping an eye towards compatibility with future Windows NT releases, that is, Windows 2000 (NT 5.0) and Windows XP (NT 5.1). More information is available at http://www.reactos.com. 2. Building ReactOS See the INSTALL file for more details. 3. More information See the doc subdirectory for some sparse notes 4.
