* - Remove dynamic_size from struct elf_resolve.Joakim Tjernlund2004-11-021-1/+9
| | | | | | | | | | - Replace all open coded dynamic handling with a function. Reduces size. - Fold special MIPS dynamic code into the dynamic_info item. - Add RELRO support. - Support linking with "-z now". - prepare for DT_RELACOUNT/DT_RELCOUNT optimization. - Add -z now to ld.so linking, this is what ld.so does anyway so let the linker know that.
* unmap ld.so.cache when dlopen() returns.Joakim Tjernlund2004-10-141-0/+1

* Second attempt to fix the INIT/FINI order. This time I think I got it right :)Joakim Tjernlund2004-09-081-26/+59
| | | | This needs testing with apps that have complex dependencies.
* Use a more appealing name, matching the function prototypeEric Andersen2004-09-071-6/+6

* Let ldso find libc's malloc function and set _dl_malloc_function.Joakim Tjernlund2004-08-261-8/+0
| | | | | | This removes some crap in libdl.c(and future libs which needs to access ldso functions). What do you think?
* Added test for RTLD_GLOBAL flag in _dl_find_hash().Joakim Tjernlund2004-08-261-2/+3
| | | | | Fixed a bug in libdl.c where the RTLD_GLOBAL was assigned wronly.

* Let ldso decide if it should relocate itselft a second time. ThisJoakim Tjernlund2004-08-172-3/+8
| | | | | | | is needed if ldso should use libcs malloc whenever possible. Fix RTLD_LAZY propagation to RTLD_NOW relocation when requested by libdl.
* Fix usage_count in ldso/libdl.Joakim Tjernlund2004-08-132-76/+35
| | | | | | | Don't' use atexit in libdl. Make destrutor in libdl actually run and to dlclose all dlopened libs. Remove dlclosed libs from the _dl_symbol_tables list.
* Mike Frysinger writes:Joakim Tjernlund2004-08-101-7/+7
| | | | | | | | | | | | | | | | | in libdl, the XXFLAGS is set incorrectly if DODEBUG=y ... it has 'I.' added to it instead of '-I.' ... this of course pisses of gcc :) find attached a patch that cleans up the XXFLAGS setting so as to minimize this kind of thing ... when asked, mjn3 said it was a kosher idea ;) and later writes: hmm it seems ldso also utilizes USE_CACHE in the code (but LIBRARY_CACHE never propogates down to the Makefiles) so the fix is to add $(LIBRARY_CACHE) while setting $(XXFLAGS) Applied with minor fixes and also fixed up ldso/Makefile to match libdl/Makefile.
* This should fix the dlsym problem Peter van Hoyweghen reported.Joakim Tjernlund2004-08-091-32/+19
| | | | However RTLD_LOCAL still doesn't work. Everything is RTLD_GLOBAL.
* Teach libdl to use normal libc symbols whenever possible, i.e. mallocEric Andersen2004-07-302-56/+33

* Per discussion with Joakim Tjernlund, all the horrible weak declarations junkEric Andersen2004-02-201-78/+96
| | | | | | in libdl pointing to the local 'foobar' function is garbage. This cleans all that up and makes the code much less horrible. Now it is only really really ugly (which is a marked improvement),
* Joakim Tjernlund writes:Eric Andersen2004-02-141-2/+6
| | | | | | | | | | | | | | | | | | Hi it is me again. 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 ...

| | | | | | | | | | ln.patch: * Define $(LN) as ln in Rules.mak. * Change all occurrences of ln into $(LN). * Change all constructs like (cd path && ln -sf foo/file file) into $(LN) -sf foo/file path/file. The latter construct is already used in a number of places so it should not be an additional compatibility problem.

* When someone would dlopen a shared lib that was already opened,Eric Andersen2003-10-092-24/+28
| | | | | | | | | we would try to re-fixup the lib's relocations with rather horrible results. So fix that by checking the the dlopened lib has already had its init functions called, which will never be the case for newly loaded libs, and skip the rest in that case. also apply a few minor fixups

* Ronald Wahl writes:Eric Andersen2002-11-152-0/+2
| | | | | | I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16.
