2007-12-03Blackfin FD-PIC patch 1/6.Bernd Schmidt
Add a new function _dl_free. In _dl_malloc, ensure we always get back a full page from mmap. Reset _dl_malloc_function and _dl_free_function when libdl is initialized.
2007-03-31Bernd Schmidt writes:Joakim Tjernlund
Currently a static libdl.a doesn't run all the constructors or destructors of the libraries it loads. I can't see a good reason for that, and it does cause aborts in the destructors it does run for things like libgcc.so on the Blackfin. Fixed with the patch below - untested in mainline, but the equivalent has been in our Blackfin tree for a while now.

Hi All, the attached patch completes my previous patch on statically linked application calling dlopen enabling the support for LD_DEBUG. Further it fixes the missing initialization of the _dl_library_path variable. This patch has been fully tested with the uClibc-nptl branch (sh4).

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.

Mips did not honour the LD_BIND_NOW env. variable or the DT_BIND_NOW flag in the dynamic section.
2004-11-10Add RTLD_LOCAL support for dlopened libs. Reported byJoakim Tjernlund
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.
2004-11-02- Remove dynamic_size from struct elf_resolve.Joakim Tjernlund
- 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.

2004-09-08Second attempt to fix the INIT/FINI order. This time I think I got it right :)Joakim Tjernlund
This needs testing with apps that have complex dependencies.
