68 | /* This file turns a regular Windows PE image into a DLL. Because of |
69 | the complexity of this operation, it has been broken down into a | |
70 | number of separate modules which are all called by the main function | |
71 | at the end of this file. This function is not re-entrant and is | |
72 | normally only called once, so static variables are used to reduce | |
73 | the number of parameters and return values required. | |

77 | /* Auto-import feature by Paul Sokolovsky | |
78 | ||
79 | Quick facts: | |
80 | ||
81 | 1. With this feature on, DLL clients can import variables from DLL | |
82 | without any concern from their side (for example, without any source | |
83 | code modifications). | |
84 | ||
85 | 2. This is done completely in bounds of the PE specification (to be fair, | |
396a2467 | 86 | there's a place where it pokes nose out of, but in practice it works). |
775cabad NC |
87 | So, resulting module can be used with any other PE compiler/linker. |
88 | ||
89 | 3. Auto-import is fully compatible with standard import method and they | |
90 | can be mixed together. | |
91 | ||
92 | 4. Overheads: space: 8 bytes per imported symbol, plus 20 for each | |
93 | reference to it; load time: negligible; virtual/physical memory: should be | |
94 | less than effect of DLL relocation, and I sincerely hope it doesn't affect | |
95 | DLL sharability (too much). | |
96 | ||
97 | Idea | |
98 | ||
99 | The obvious and only way to get rid of dllimport insanity is to make client | |
100 | access variable directly in the DLL, bypassing extra dereference. I.e., | |
396a2467 | 101 | whenever client contains something like |
775cabad NC |
102 | |
103 | mov dll_var,%eax, | |
104 | ||
105 | address of dll_var in the command should be relocated to point into loaded | |
106 | DLL. The aim is to make OS loader do so, and than make ld help with that. | |
107 | Import section of PE made following way: there's a vector of structures | |
108 | each describing imports from particular DLL. Each such structure points | |
396a2467 | 109 | to two other parallel vectors: one holding imported names, and one which |
775cabad NC |
110 | will hold address of corresponding imported name. So, the solution is |
111 | de-vectorize these structures, making import locations be sparse and | |
112 | pointing directly into code. Before continuing, it is worth a note that, | |
113 | while authors strives to make PE act ELF-like, there're some other people | |
114 | make ELF act PE-like: elfvector, ;-) . | |
115 | ||
116 | Implementation | |
117 | ||
118 | For each reference of data symbol to be imported from DLL (to set of which | |
119 | belong symbols with name <sym>, if __imp_<sym> is found in implib), the | |
120 | import fixup entry is generated. That entry is of type | |
53baae48 | 121 | IMAGE_IMPORT_DESCRIPTOR and stored in .idata$2 subsection. Each |
775cabad NC |
122 | fixup entry contains pointer to symbol's address within .text section |
123 | (marked with __fuN_<sym> symbol, where N is integer), pointer to DLL name | |
124 | (so, DLL name is referenced by multiple entries), and pointer to symbol | |
125 | name thunk. Symbol name thunk is singleton vector (__nm_th_<symbol>) | |
126 | pointing to IMAGE_IMPORT_BY_NAME structure (__nm_<symbol>) directly | |
00479ba8 | 127 | containing imported name. Here comes that "on the edge" problem mentioned |
775cabad NC |
128 | above: PE specification rambles that name vector (OriginalFirstThunk) |
129 | should run in parallel with addresses vector (FirstThunk), i.e. that they | |
130 | should have same number of elements and terminated with zero. We violate | |
396a2467 | 131 | this, since FirstThunk points directly into machine code. But in practice, |
370dfff4 | 132 | OS loader implemented the sane way: it goes through OriginalFirstThunk and |
775cabad NC |
133 | puts addresses to FirstThunk, not something else. It once again should be |
134 | noted that dll and symbol name structures are reused across fixup entries | |
135 | and should be there anyway to support standard import stuff, so sustained | |
136 | overhead is 20 bytes per reference. Other question is whether having several | |
137 | IMAGE_IMPORT_DESCRIPTORS for the same DLL is possible. Answer is yes, it is | |
138 | done even by native compiler/linker (libth32's functions are in fact reside | |
139 | in windows9x kernel32.dll, so if you use it, you have two | |
140 | IMAGE_IMPORT_DESCRIPTORS for kernel32.dll). Yet other question is whether | |
141 | referencing the same PE structures several times is valid. The answer is why | |
396a2467 | 142 | not, prohibiting that (detecting violation) would require more work on |
775cabad NC |
143 | behalf of loader than not doing it. |
