- Final ROSRTL removal patch. The next patch will remove the actual
library and code.
- Changes:
- CreateProcess
* Cleanup creation of the initial thread using new utility
functions and remove rosrtl
* Almost entirely rewrote the function to support features such
as:
- SxS (locally only, patch will follow),
- SFP (SAFER) (locally only, patch will follow),
- DllPaths (locally only, patch will follow),
- Proper process environment/paramter block creation
- Proper console handle management (needs more work in
kernel32/csr),
- Tokens/CreateProcessAsUser (locally only, patch will
follow),
- Simpler code for path lookup, and more robust.
- Support for "auto-correction" (see Raymond Chen's blog)
- 16-bit/NE detection
- A variety of creation flags are now properly supported
- Added support for an undocumented-yet-known (see comment)
shell flag
- Alert for flags we don't support yet
- Catch invalid flag combinations and other caller errors
- Improve and correct path searcing to use documented
behaviours
- Created a multitude of helper functions to make the code
easier to read
and allow them to be used for other apis as time goes on.
- BaseProcessStartup
* Call NtSetThreadInformation to let the Kernel know of the
Thread's Start Address.
* Correct prototype of Thread Startup function for this case.
This fixes MANY things, some of which may not be evident, and possibly
creates regressions which I have not yet seen but will try to correct.
Some of these may be caused by the fact that I've seen code send
CreateProcessW incorrect flags. Some things of note: DO NOT send partial
names as "lpApplicationName". It's not supposed to work unless you're
in
the same current directory. Also, do NOT send CREATE_UNICODE_ENVIRONMENT
if you don't have a unicode environement, and vice-versa. I've seen lots
of code doing mistakes related to this. I hope you appreciate this patch
and won't all jump on me for possbile regressions :(.
