This is the latest ldso patch. the NEW weak symbol handling works now with a little special handling in _dl_find_hash(). You get to chose if you want the new or old handling :) There was 2 missing _dl_check_if_named_library_is_loaded() calls in _dlopen(). I then disabled the _dl_check_if_named_library_is_loaded() in dl-elf.c since it is rendundant. Question, why does some _dl_linux_resolver(), like i386, have 2 calls to _dl_find_hash()? I think that is wrong, isn't it? I really hope you can check this out soon ... --- ldso/include/dl-elf.h | 13 +++++++++++++ ldso/include/dl-hash.h | 3 +-- 2 files changed, 14 insertions(+), 2 deletions(-) (limited to 'ldso/include') diff --git a/ldso/include/dl-elf.h b/ldso/include/dl-elf.h index 4cab5505f..b0a475319 100644 --- a/ldso/include/dl-elf.h +++ b/ldso/include/dl-elf.h @@ -92,6 +92,19 @@ extern int _dl_fixup(struct dyn_elf *rpnt, int flag); # define UNSUPPORTED_RELOC_STR "RELA" #endif +/* Reloc type classes as returned by elf_machine_type_class(). + ELF_RTYPE_CLASS_PLT means this reloc should not be satisfied by + some PLT symbol, ELF_RTYPE_CLASS_COPY means this reloc should not be + satisfied by any symbol in the executable.
