* Do not create any files (dl-progname.h) in ldso anymorePeter S. Mazinger2005-11-211-1/+1

* Moved guard_setup to dl-osinfo.h (used commonly by ldso and libc). Renamed ↵Peter S. Mazinger2005-10-271-9/+10
| | | | to _dl_setup_stack_chk_guard, as in glibc. SSP requires now binutils-2.16.1 and newer. Add NOT_IN_libc/IS_IN_libc. Began using -DSHARED in uClibc_main.c, there are more candidates in there. Move back dl_protect_relro to it's earlier place.
* Forgotten to commit libdl.c, change __LIBDL_SHARED__ to SHARED.Peter S. Mazinger2005-10-141-4/+4

| | | | | | I use an implementation for malloc()/free() which is sensible about using data after freed. In libdl.c, rpnt1->next->next is accessed after rpnt1->next is freed. Attached patch fixes that problem.

* Add dependency on ld-uClibc.so.0 for libdl.so.Joakim Tjernlund2005-08-011-19/+15

| | | | | | RPATH sematics changed to match RUNPATH. Only difference is that RPATH is searched before LD_LIBRARY_PATH and RUNPATH after. This is not complete but better than the current mess(I think).

* Moved the addition of load address from the fast pathJoakim Tjernlund2005-03-291-3/+3

* Add BIND NOW support to MIPS.Joakim Tjernlund2004-11-171-8/+10
| | | | | Mips did not honour the LD_BIND_NOW env. variable or the DT_BIND_NOW flag in the dynamic section.
* Add RTLD_LOCAL support for dlopened libs. Reported byJoakim Tjernlund2004-11-101-11/+25
| | | | | | | Andrew de Quincey, who has been most helpful getting this sorted out, thanks. Thanks also to Peter Mazinger who did alot of testing. Removed all traces of dl_parse_copy_information() since it is no longer used.
* - 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.

* Second attempt to fix the INIT/FINI order. This time I think I got it right :)Joakim Tjernlund2004-09-081-26/+59

* 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 Tjernlund2004-08-171-2/+7
| | | | | | | 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 Tjernlund2004-08-131-75/+34
| | | | | | | 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.
* This should fix the dlsym problem Peter van Hoyweghen reported.Joakim Tjernlund2004-08-091-32/+19

| | | | | | | | | | | | | | | | | | 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 ...
* Based on a problem report and patch from Florian Schirmer, fix a compileEric Andersen2004-02-121-3/+3
| | | | | | problem with mips -- contrary to my expectation gcc on mips _always_ defines __PIC__ which breaks the assumption inherent in my code. This should fix things up.
