- Auto-import feature by Paul Sokolovsky
-
- Quick facts:
-
- 1. With this feature on, DLL clients can import variables from DLL
- without any concern from their side (for example, without any source
- code modifications).
-
- 2. This is done completely in bounds of the PE specification (to be fair,
- there's a place where it pokes nose out of, but in practise it works).
- So, resulting module can be used with any other PE compiler/linker.
-
- 3. Auto-import is fully compatible with standard import method and they
- can be mixed together.
-
- 4. Overheads: space: 8 bytes per imported symbol, plus 20 for each
- reference to it; load time: negligible; virtual/physical memory: should be
- less than effect of DLL relocation, and I sincerely hope it doesn't affect
- DLL sharability (too much).
-
- Idea
-
- The obvious and only way to get rid of dllimport insanity is to make client
- access variable directly in the DLL, bypassing extra dereference. I.e.,
- whenever client contains someting like
-
- mov dll_var,%eax,
-
- address of dll_var in the command should be relocated to point into loaded
- DLL. The aim is to make OS loader do so, and than make ld help with that.
- Import section of PE made following way: there's a vector of structures
- each describing imports from particular DLL. Each such structure points
- to two other parellel vectors: one holding imported names, and one which
- will hold address of corresponding imported name. So, the solution is
- de-vectorize these structures, making import locations be sparse and
- pointing directly into code. Before continuing, it is worth a note that,
- while authors strives to make PE act ELF-like, there're some other people
- make ELF act PE-like: elfvector, ;-) .
-
- Implementation
-
- For each reference of data symbol to be imported from DLL (to set of which
- belong symbols with name <sym>, if __imp_<sym> is found in implib), the
- import fixup entry is generated. That entry is of type
- IMAGE_IMPORT_DESCRIPTOR and stored in .idata$3 subsection. Each
- fixup entry contains pointer to symbol's address within .text section
- (marked with __fuN_<sym> symbol, where N is integer), pointer to DLL name
- (so, DLL name is referenced by multiple entries), and pointer to symbol
- name thunk. Symbol name thunk is singleton vector (__nm_th_<symbol>)
- pointing to IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly
- containing imported name. Here comes that "om the edge" problem mentioned
- above: PE specification rambles that name vector (OriginalFirstThunk)
- should run in parallel with addresses vector (FirstThunk), i.e. that they
- should have same number of elements and terminated with zero. We violate
- this, since FirstThunk points directly into machine code. But in practise,
- OS loader implemented the sane way: it goes thru OriginalFirstThunk and
- puts addresses to FirstThunk, not something else. It once again should be
- noted that dll and symbol name structures are reused across fixup entries
- and should be there anyway to support standard import stuff, so sustained
- overhead is 20 bytes per reference. Other question is whether having several
- IMAGE_IMPORT_DESCRIPTORS for the same DLL is possible. Answer is yes, it is
- done even by native compiler/linker (libth32's functions are in fact reside
- in windows9x kernel32.dll, so if you use it, you have two
- IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is whether
- referencing the same PE structures several times is valid. The answer is why
- not, prohibitting that (detecting violation) would require more work on
- behalf of loader than not doing it.
