|
|
*
|
|
* This is an implementation of the services of the Win32s VxD.
|
|
* Since official documentation of these does not seem to be available,
|
|
* certain arguments of some of the services remain unclear.
|
|
*
|
|
* FIXME: The following services are currently unimplemented:
|
|
* Exception handling (0x01, 0x1C)
|
|
* Debugger support (0x0C, 0x14, 0x17)
|
|
* Low-level memory access (0x02, 0x03, 0x0A, 0x0B)
|
|
* Memory Statistics (0x1B)
|
|
*
|
|
*
|
|
* We have a specific problem running Win32s on Linux (and probably also
|
|
* the other x86 unixes), since Win32s tries to allocate its main 'flat
|
|
* code/data segment' selectors with a base of 0xffff0000 (and limit 4GB).
|
|
* The rationale for this seems to be that they want one the one hand to
|
|
* be able to leave the Win 3.1 memory (starting with the main DOS memory)
|
|
* at linear address 0, but want at other hand to have offset 0 of the
|
|
* flat data/code segment point to an unmapped page (to catch NULL pointer
|
|
* accesses). Hence they allocate the flat segments with a base of 0xffff0000
|
|
* so that the Win 3.1 memory area at linear address zero shows up in the
|
|
* flat segments at offset 0x10000 (since linear addresses wrap around at
|
|
* 4GB). To compensate for that discrepancy between flat segment offsets
|
|
* and plain linear addresses, all flat pointers passed between the 32-bit
|
|
* and the 16-bit parts of Win32s are shifted by 0x10000 in the appropriate
|
|
* direction by the glue code (mainly) in W32SKRNL and WIN32S16.
|
|
*
|
|
* The problem for us is now that Linux does not allow a LDT selector with
|
|
* base 0xffff0000 to be created, since it would 'see' a part of the kernel
|
|
* address space. To address this problem we introduce *another* offset:
|
|
* We add 0x10000 to every linear address we get as an argument from Win32s.
|
|
* This means especially that the flat code/data selectors get actually
|
|
* allocated with base 0x0, so that flat offsets and (real) linear addresses
|
|
* do again agree! In fact, every call e.g. of a Win32s VxD service now
|
|
* has all pointer arguments (which are offsets in the flat data segment)
|
|
* first reduced by 0x10000 by the W32SKRNL glue code, and then again
|
|
* increased by 0x10000 by *our* code.
|
|
*
|
|
* Note that to keep everything consistent, this offset has to be applied by
|
|
* every Wine function that operates on 'linear addresses' passed to it by
|
|
* Win32s. Fortunately, since Win32s does not directly call any Wine 32-bit
|
|
* API routines, this affects only two locations: this VxD and the DPMI
|
|
* handler. (NOTE: Should any Win32s application pass a linear address to
|
|
* any routine apart from those, e.g. some other VxD handler, that code
|
|
* would have to take the offset into account as well!)
|
|
*
|
|
* The offset is set the first time any application calls the GetVersion()
|
|
* service of the Win32s VxD. (Note that the offset is never reset.)

* hack the memory image of WIN32S16 so that it doesn't try
|
|
* to access the GDT directly ...
|
|
*
|
|
* The first code segment of WIN32S16 (version 1.30) contains
|
|
* an unexported function somewhere between the exported functions
|
|
* SetFS and StackLinearToSegmented that tries to find a selector
|
|
* in the LDT that maps to the memory image of the LDT itself.
|
|
* If it succeeds, it stores this selector into a global variable
|
|
* which will be used to speed up execution by using this selector
|
|
* to modify the LDT directly instead of using the DPMI calls.
|
|
*
|
|
* To perform this search of the LDT, this function uses the
|
|
* sgdt and sldt instructions to find the linear address of
|
|
* the (GDT and then) LDT. While those instructions themselves
|
|
* execute without problem, the linear address that sgdt returns
|
|
* points (at least under Linux) to the kernel address space, so
|
|
* that any subsequent access leads to a segfault.
|
|
*
|
|
* Fortunately, WIN32S16 still contains as a fallback option the
|
|
* mechanism of using DPMI calls to modify LDT selectors instead
|
|
* of direct writes to the LDT. Thus we can circumvent the problem
|
|
* by simply replacing the first byte of the offending function
|
|
* with an 'retf' instruction. This means that the global variable
|
|
* supposed to contain the LDT alias selector will remain zero,
|
|
* and hence WIN32S16 will fall back to using DPMI calls.
|
|
*
|
|
* The heuristic we employ to _find_ that function is as follows:
|
|
* We search between the addresses of the exported symbols SetFS
|
|
* and StackLinearToSegmented for the byte sequence '0F 01 04'
|
|
* (this is the opcode of 'sgdt [si]'). We then search backwards
|
|
* from this address for the last occurrence of 'CB' (retf) that marks
|
|
* the end of the preceding function. The following byte (which
|
|
* should now be the first byte of the function we are looking for)
|
|
* will be replaced by 'CB' (retf).
|
|
*
|
|
* This heuristic works for the retail as well as the debug version
|
|
* of Win32s version 1.30. For versions earlier than that this
|
|
* hack should not be necessary at all, since the whole mechanism
|
|
* ('PERF130') was introduced only in 1.30 to improve the overall
|
|
* performance of Win32s.
