/* Macro for defining "auto-load" functions.
|
|
|
|
|
* Note that this is self-modifying code *gasp*.
|
|
|
|
|
* The first invocation of a routine will trigger the loading of
|
|
|
|
|
* the DLL. This will then be followed by the discovery of
|
|
|
|
|
* the procedure's entry point, which is placed into the location
|
|
|
|
|
* pointed to by the stack pointer. This code then changes
|
|
|
|
|
* the "call" operand which invoked it to a "jmp" which will
|
|
|
|
|
* transfer directly to the DLL function on the next invocation.
|
|
|
|
|
*
|
|
|
|
|
* Subsequent calls to routines whose transfer address has not been
|
|
|
|
|
* determined will skip the "load the dll" step, starting at the
|
|
|
|
|
* "discovery of the entry point" step.
|
|
|
|
|
*
|
|
|
|
|
* So, immediately following the the call to one of the above routines
|
|
|
|
|
* we have:
|
|
|
|
|
* DLL info (4 bytes) Pointer to a block of information concerning
|
|
|
|
|
* the DLL (see below).
|
|
|
|
|
* DLL args (4 bytes) The number of arguments pushed on the stack by
|
|
|
|
|
* the call. If this is an odd value then this
|
|
|
|
|
* is a flag that non-existence of this function
|
|
|
|
|
* is not a fatal error
|
|
|
|
|
* func name (n bytes) asciz string containing the name of the function
|
|
|
|
|
* to be loaded.
|
|
|
|
|
*
|
|
|
|
|
* The DLL info block consists of the following
|
|
|
|
|
* load_state (4 bytes) Pointer to a word containing the routine used
|
|
|
|
|
* to eventually invoke the function. Initially
|
|
|
|
|
* points to an init function which loads the
|
|
|
|
|
* DLL, gets the process's load address,
|
|
|
|
|
* changes the contents here to point to the
|
|
|
|
|
* function address, and changes the call *(%eax)
|
|
|
|
|
* to a jmp func. If the initialization has been
|
|
|
|
|
* done, only the load part is done.
|
|
|
|
|
* DLL handle (4 bytes) The handle to use when loading the DLL.
|
|
|
|
|
* DLL locker (4 bytes) Word to use to avoid multi-thread access during
|
|
|
|
|
* initialization.
|
|
|
|
|
* extra init (4 bytes) Extra initialization function.
|
|
|
|
|
* DLL name (n bytes) asciz string containing the name of the DLL.
