/* Notes:
|
|
* Before you start changing something in this file be aware of the following:
|
|
*
|
|
* - There are several functions called recursively. In a very subtle and
|
|
* obscure way. DLLs can reference each other recursively etc.
|
|
* - If you want to enhance, speed up or clean up something in here, think
|
|
* twice WHY it is implemented in that strange way. There is usually a reason.
|
|
* Though sometimes it might just be lazyness ;)
|
|
* - In PE_MapImage, right before fixup_imports() all external and internal
|
|
* state MUST be correct since this function can be called with the SAME image
|
|
* AGAIN. (Thats recursion for you.) That means MODREF.module and
|
|
* NE_MODULE.module32.
|
|
* - No, you (usually) cannot use Linux mmap() to mmap() the images directly.
|
|
*
|
|
* The problem is, that there is not direct 1:1 mapping from a diskimage and
|
|
* a memoryimage. The headers at the start are mapped linear, but the sections
|
|
* are not. For x86 the sections are 512 byte aligned in file and 4096 byte
|
|
* aligned in memory. Linux likes them 4096 byte aligned in memory (due to
|
|
* x86 pagesize, this cannot be fixed without a rather large kernel rewrite)
|
|
* and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM)
|
|
* and other byte blocksizes, we can't do this. However, this could be less
|
|
* difficult to support... (See mm/filemap.c).
|
|
* - All those function map things into a new addresspace. From the wrong
|
|
* process and the wrong thread. So calling other API functions will mess
|
|
* things up badly sometimes.
