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