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

/* 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 practice it works).
2001-09-14 16:19:05 +02:00
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 something like
2001-09-14 16:19:05 +02:00
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 parallel vectors: one holding imported names, and one which
2001-09-14 16:19:05 +02:00
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 practice,
2001-09-14 16:19:05 +02:00
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, prohibiting that (detecting violation) would require more work on
2001-09-14 16:19:05 +02:00
behalf of loader than not doing it.

bfd/ * section.c (struct sec): Rename "_cooked_size" to "size". Rename "_raw_size" to "rawsize". (STD_SECTION): Adjust comments. (bfd_set_section_size, bfd_get_section_contents): Use size. (bfd_malloc_and_get_section): New function. * bfd-in.h (bfd_section_size, bfd_get_section_size): Use size. * coff-sh.c (sh_relax_section): Alloc coff_section_data struct early. Correctly free reloc and contents memory. * elf-eh-frame.c (_bfd_elf_discard_section_eh_frame): Delete FIXME and fake CIE now that we can shink section size to zero.

Use _bfd_elf_section_offset. * stabs.c (_bfd_stab_section_offset_): Remove unused args and unneeded indirection. * elf.c (_bfd_elf_section_offset): .. and update call. * libbfd-in.h (_bfd_stab_section_offset): Update prototype. * libbfd.h: Regenerate. * bfd-in2.h: Regenerate. Replace occurrences of "_raw_size" and "_cooked_size" in most places with "size". Set new "rawsize" for stabs, eh_frame, and SEC_MERGE sections. Use "rawsize", if non-zero, for bfd_get_section_contents calls if the section might be a stabs, eh_frame, or SEC_MERGE section. Similarly use "rawsize", if non-zero, in reloc functions to validate reloc addresses. Use new bfd_malloc_and_get_section in most places where bfd_get_section_contents was called. Expand all occurrences of bfd_section_size and bfd_get_section_size.

(generate_reloc): add optional extra debugging (pe_dll_generate_def_file): eliminate extraneous initial blank line in output (make_one): enlarge symtab to make room for __nm__ symbols (DATA auto-import support). (make_singleton_name_thunk): New function. (make_import_fixup_mark): New function. (make_import_fixup_entry): New function. (pe_create_import_fixup): New function. (add_bfd_to_link): Specify that 'name' argument is a CONST char *. * pe-dll.h: declare new variable pe_dll_extra_pe_debug; declare new functions pe_walk_relocs_of_symbol and pe_create_import_fixup. * emultempl/pe.em: add new options --enable-auto-import, --disable-auto-import, and --enable-extra-pe-debug. (make_import_fixup): New function. (pe_find_data_imports): New function. (pr_sym): New function. (gld_${EMULATION_NAME}_after_open): Add optional extra pe debugging. Call pe_find_data_imports. Mark .idata as DATA, not CODE. 2001-08-02 Charles Wilson <cwilson@ece.gatech.edu> * ld.texinfo: add additional documentation for --export-all-symbols. Document --out-implib, --enable-auto-image-base, --disable-auto-image-base, --dll-search-prefix, --enable-auto-import, and --disable-auto-import. * ldint.texinfo: Add detailed documentation on auto-import implementation.
