| 2008-05-05 | Constantly fill in the program header pointer and count in elf_object_t | Kurt Miller | |
| for all objects which simplifies phdr usage in a few places. "go for it" drahn@ | |||
| 2008-04-09 | Improve support for shared libs linked at non-zero addreses: | Kurt Miller | |
| - rename private values in struct elf_object to better describe their meaning: s/load_offs/obj_base/ "object's address '0' base" s/load_addr/load_base/ "The base address of the loadable segments" - gdb needs the obj_base value so swap positions with load_base in struct elf_object - fix a few occurrences of where load_base was used instead of obj_base. With help and okay drahn@ | |||
| 2006-05-03 | prebind - how to prelink a binary without throwing security out the window | Dale Rahn | |
| Prelink fixes the address of libraries making 'return to libc' attacks trival, prebind uses a different method to achieve most of the same gains, however without adding any security conerns. Still under development, now in-tree. | |||
| 2005-11-09 | add RTLD_NOW support to dlopen and propogate -z now to dep libs. | Kurt Miller | |
| ok drahn@ | |||
| 2005-10-21 | using _dl_link_grpsym to increment refcounts made _dl_notify_unload_shlib | Kurt Miller | |
| simpler, however it broke ldd refcount output. use _dl_link_child to increment refcounts and adjust _dl_notify_unload_shlib to match. work by drahn@ and myself. ok drahn@ | |||
| 2005-10-17 | Fix possible buffer overflow caused by unknown tags in the range | Mark Kettenis | |
| [DT_LOPROC, DT_HIPROC]. ok kurt@ | |||
| 2005-10-12 | Split grpsym_list creation away from child_list creation and change | Kurt Miller | |
| grpsym_list order to match Sun's docs. Also corrects bugs where grpsym_list was either not created or partially created. | |||
| 2005-10-09 | introduce object ref count macros (suggested by dale). no functional | Kurt Miller | |
| change. | |||
| 2005-10-07 | rename dload_list to grpsym_list which better represents its usage. | Kurt Miller | |
| 2005-10-06 | remove dep_next "shadow object" dead code. | Kurt Miller | |
| 2005-10-06 | separate load group references from dep lib child/dload lists. move load | Kurt Miller | |
| group refs to own per object ref counter (grprefcount) and list (grpref_list). corrects more complex load group ref cases and side effects from initial implementation. design ideas and ok drahn@ | |||
| 2005-10-03 | refcount corrections: count common dep libs once and centralize dep lib | Kurt Miller | |
| refcount increments to _dl_link_sub. adjust _dl_notify_unload_shlib to match new refcount method. ok drahn@ | |||
| 2005-10-01 | handle references to load groups caused by dlopen()ing of depenant | Dale Rahn | |
| members of the load group. work by kurt@ and myself | |||
| 2005-09-28 | keep a state flag if a library has been unloaded, and then free the list | Dale Rahn | |
| seperately ok kurt@ | |||
| 2005-09-28 | keep track of opencounts for dlopened objects, so that they | Dale Rahn | |
| get unloaded the right number of times on exit. | |||
| 2005-09-22 | knf; ok drahn | Theo de Raadt | |
| 2005-09-22 | Use std missing symbol print instead of MD custom, do not warn on weak | Dale Rahn | |
| undefined symbols, or count them as failures. inspired kurt@ | |||
| 2005-09-21 | Simplify the internal symbol finding API, with some cleanup, prep for | Dale Rahn | |
| next step. ok kurt@ | |||
| 2005-09-19 | stop searching after first matching symbol is found. okay drahn@ | Kurt Miller | |
| 2005-09-19 | simplify code by putting executable in misnamed _dlopened_child_list, | Dale Rahn | |
| also move RTLD_NEXT/RTLD_SELF code into that code, it is a single test. okay kurt@ | |||
| 2005-09-16 | Now that the bug requiring it has been fixed, remove the lastchance kludge | Dale Rahn | |
| ok kurt@ | |||
| 2005-09-16 | Rework symbol lookup to more closely match sun's documentation, now | Dale Rahn | |
| treats dlopens as load groups. ok kurt@ | |||
| 2005-05-10 | Recommit the destructor order fix, now that the amd64 bug was fixed. | Dale Rahn | |
| 'no problem' pval@ | |||
| 2005-04-06 | backout -- breaks at least amd64; spotted by marc | Theo de Raadt | |
| 2005-04-05 | Do a better job of running destructors in the right order. | Dale Rahn | |
| 2004-07-05 | Fix an issue where a shared library could be loaded at two different | Kjell Wooding | |
| locations by resolving all dlopens back to a dev/inode. i.e. Don't load a library if the dev/inode it stats back to matches one already in our list. fix started (and ok'ed) drahn@. ok deraadt@. "doesn't break anything yet" pval@ art@ brad@ | |||
| 2004-05-25 | return object* the symbol is in for _dl_find_symbol*; drahn@ ok | Michael Shalayeff | |
| 2004-05-25 | spacing | Theo de Raadt | |
| 2003-09-04 | Symbol cache for GOT lookup. When a symbol is found it is saved in a cache | Dale Rahn | |
| for future lookups in the same GOT relocation table. Uses static buffer for small symbol tables, mmap for larger ones. ok deraadt@ | |||
| 2003-09-02 | Fix PR 3371, symbol lookup in dlopen()ed objects is not correct. Correct | Dale Rahn | |
| behavior for RTLD_GLOBAL/RTLD_LOCAL is now supported. ok espie@ | |||
| 2003-06-22 | Dynamic linking random order fixes. This enables random library ordering. | Dale Rahn | |
| Tested by naddy@ and others. | |||
| 2003-06-09 | pefo 3/4 licence cleanups | Theo de Raadt | |
| 2003-02-02 | knf & ansi; drahn ok | Theo de Raadt | |
| 2003-01-30 | Change the constructor execution order to initialize dependant libraries | Dale Rahn | |
| first. This mirrors the commit espie put in a.out ld.so recently. | |||
| 2002-11-23 | Remove some error messages which were incorrectly printed. Some cleanup. | Dale Rahn | |
| ok pvalchev@ | |||
| 2002-11-14 | Make error messages on symbol lookup failures more useful. | Dale Rahn | |
| 2002-08-23 | Change arguments to _dl_find_symbol() myself, warnnotfound, and inplt into | Dale Rahn | |
| a single flags field with bits representing each. Use defines to create the appropriate masks. Add a new argument sym_size to warn about symbols which have the incorrect size. This replaces 'ifdef notyet' code which was in several of the md files with a single version. sym_size == 0 means do not check, and symbols of type FUNC are not checked. | |||
| 2002-08-11 | Fix for Elfbug, the Xtiherit problem which has been seen on most OpenBSD | Dale Rahn | |
| ELF dynamic systems. This was due to an oddity in ELF where the address of fuctions refer to the PLT address in the program, rather than the actual function address. | |||

| 2002-05-24 | various KNF | Theo de Raadt | |
| 2002-03-17 | Keep _dl_last_object in sync with reality if last element in list is deleted. | Dale Rahn | |
| allocated memory is not necessarily 0ed, make sure next pointer is inited. | |||
| 2002-02-21 | cleanup of MD/MI ld.so (elf), most changes by art@ cleanup by me. | Dale Rahn | |
| tested on alpha sparc64 powerpc. | |||
| 2001-09-25 | Cleaner hash bucket init and some KNF. | Artur Grabowski | |

| 2001-05-31 | unsigned long, not u_int32_t | Artur Grabowski | |
| 2001-04-02 | Cleanup for 64bit support. | Dale Rahn | |
| Pieces by art, niklas and me. Only tested on powerpc. | |||
| 2000-06-13 | Initial import of ELF ld.so. This was written indepently of the gnu rtld | Dale S. Rahn | |
| code and is fully BSD copyrighted. This initial import contains a mostly working mips and partially working powerpc version. No support for ld.so.hints or system run path exists. | |||
