Add support for Windows/x86-64 binaries to Project Evil.

Browse Source 
Ville-Pertti Keinonen (will at exomi dot comohmygodnospampleasekthx)
deserves a big thanks for submitting initial patches to make it
work. I have mangled his contributions appropriately.

The main gotcha with Windows/x86-64 is that Microsoft uses a different
calling convention than everyone else. The standard ABI requires using
6 registers for argument passing, with other arguments on the stack.
Microsoft uses only 4 registers, and requires the caller to leave room
on the stack for the register arguments incase the callee needs to
spill them. Unlike x86, where Microsoft uses a mix of _cdecl, _stdcall
and _fastcall, all routines on Windows/x86-64 uses the same convention.
This unfortunately means that all the functions we export to the
driver require an intermediate translation wrapper. Similarly, we have
to wrap all calls back into the driver binary itself.

The original patches provided macros to wrap every single routine at
compile time, providing a secondary jump table with a customized
wrapper for each exported routine. I decided to use a different approach:
the call wrapper for each function is created from a template at
runtime, and the routine to jump to is patched into the wrapper as
it is created. The subr_pe module has been modified to patch in the
wrapped function instead of the original. (On x86, the wrapping
routine is a no-op.)

There are some minor API differences that had to be accounted for:

- KeAcquireSpinLock() is a real function on amd64, not a macro wrapper
  around KfAcquireSpinLock()
- NdisFreeBuffer() is actually IoFreeMdl(). I had to change the whole
  NDIS_BUFFER API a bit to accomodate this.

Bugs fixed along the way:
- IoAllocateMdl() always returned NULL
- kern_windrv.c:windrv_unload() wasn't releasing private driver object
  extensions correctly (found thanks to memguard)

This has only been tested with the driver for the Broadcom 802.11g
chipset, which was the only Windows/x86-64 driver I could find.

* AMD64 support. Microsoft uses a different calling convention

*
* The three major differences we're concerned with are:
*
* - The first 4 register-sized arguments are passed in the
* %rcx, %rdx, %r8 and %r9 registers, and the rest are pushed
* onto the stack. (The ELF ABI uses 6 registers, not 4).
*
* - The caller must reserve space on the stack for the 4
* register arguments in case the callee has to spill them.
*
* - The stack myst be 16-byte aligned by the time the callee
* executes. A call instruction implicitly pushes an 8 byte
* return address onto the stack. We have to make sure that
* the amount of space we consume, plus the return address,
* is a multiple of 16 bytes in size. This means that in
* some cases, we may need to chew up an extra 8 bytes on
* the stack that will be unused.
*
* On the bright side, Microsoft seems to be using just the one

* The NDIS "buffer" manipulation functions are somewhat misnamed.

* to obtain the virtual address of the DMA-able region.
* NdisAllocateBufferPool() is analagous to bus_dma_tag_create().
* The NDIS "buffer" is really an MDL (memory descriptor list)
* which is used to describe a buffer in a way that allows it
* to mapped into different contexts. We have to be careful how
* we handle them: in some versions of Windows, the NdisFreeBuffer()
* routine is an actual function in the NDIS API, but in others
* it's just a macro wrapper around IoFreeMdl(). There's really
* no way to use the 'descnum' parameter to count how many
* "buffers" are allocated since in order to use IoFreeMdl() to
* dispose of a buffer, we have to use IoAllocateMdl() to allocate
* them, and IoAllocateMdl() just grabs them out of the heap.

/*
* Wrapper for handling up to 16 arguments. We can't really
* know how many arguments the caller will pass us. I'm taking an
* educated guess that we'll never get over 16. Handling too
* few arguments is bad. Handling too many is inefficient, but
* not fatal. If someone can think of a way to handle an arbitrary
* number of arguments with more elegant code, freel free to let
* me know.
*
* Standard amd64 calling conventions specify the following registers
* to be used for passing the first 6 arguments:
*
* %rdi, %rsi, %rdx, %rcx, %r8, %r9
*
* Further arguments are passed on the stack (the 7th argument is
* located immediately after the return address).
*
* Windows x86_64 calling conventions only pass the first 4
* arguments in registers:
*
* %rcx, %rdx, %r8, %r9
*
* Even when arguments are passed in registers, the stack must have
* space reserved for those arguments. Thus the 5th argument (the
* first non-register argument) is placed 32 bytes after the return
* address. Additionally, %rdi and %rsi must be preserved. (These
* two registers are not scratch registers in the standard convention.)
*
* Note that in this template, we load a contrived 64 bit address into
* %r11 to represent our jump address. This is to guarantee that the
* assembler leaves enough room to patch in an absolute 64-bit address
* later. The idea behind this code is that we want to avoid having to
* manually create all the wrapper functions at compile time with
* a bunch of macros. This is doable, but a) messy and b) requires
* us to maintain two separate tables (one for the UNIX function
* pointers and another with the wrappers). This means I'd have to
* update two different tables each time I added a function.
*
* To avoid this, we create the wrappers at runtime instead. The
* image patch tables now contain two pointers: one two the normal
* routine, and a blank one for the wrapper. To construct a wrapper,
* we allocate some memory and copy the template function into it,
* then patch the function pointer for the routine we want to wrap
* into the newly created wrapper. The subr_pe module can then
* simply patch the wrapper routine into the jump table into the
* windows image. As a bonus, the wrapper pointer not only serves
* as the wrapper entry point address, it's also a data pointer
* that we can pass to free() later when we unload the module.
