34
* Before you start changing something in this file be aware of the following:
36
* - There are several functions called recursively. In a very subtle and
37
* obscure way. DLLs can reference each other recursively etc.
38
* - If you want to enhance, speed up or clean up something in here, think
39
* twice WHY it is implemented in that strange way. There is usually a reason.
40
* Though sometimes it might just be lazyness ;)
41
* - In PE_MapImage, right before fixup_imports() all external and internal
42
* state MUST be correct since this function can be called with the SAME image
43
* AGAIN. (Thats recursion for you.) That means MODREF.module and
45
* - Sometimes, we can't use Linux mmap() to mmap() the images directly.
47
* The problem is, that there is not direct 1:1 mapping from a diskimage and
48
* a memoryimage. The headers at the start are mapped linear, but the sections
49
* are not. Older x86 pe binaries are 512 byte aligned in file and 4096 byte
50
* aligned in memory. Linux likes them 4096 byte aligned in memory (due to
51
* x86 pagesize, this cannot be fixed without a rather large kernel rewrite)
52
* and 'blocksize' file-aligned (offsets). Since we have 512/1024/2048 (CDROM)
53
* and other byte blocksizes, we can't always do this. We *can* do this for
54
* newer pe binaries produced by MSVC 5 and later, since they are also aligned
55
* to 4096 byte boundaries on disk.
