| * VXD_Win32s |
| * |
| * 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 segement) |
| * 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 application of the offset is triggered by marking the current process |
| * as a Win32s process by setting the PDB32_WIN32S_PROC flag in the process |
| * database. This is done the first time any application calls the GetVersion() |
| * service of the Win32s VxD. (Note that the flag is never removed.) |

| * If this is the first time we are called for this process, |
| * 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 occurrance of 'CB' (retf) that marks |
| * the end of the preceeding 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. |
