| 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. | |||
| 2006-05-03 | Rewrite the ld.so syscall stubs as macros. no binary change. | Dale Rahn | |
| 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@ | |||
| 2005-09-16 | Rework symbol lookup to more closely match sun's documentation, now | Dale Rahn | |
| treats dlopens as load groups. ok kurt@ | |||
| 2004-05-25 | provide one version of _dl_bcopy instead of copy in every arch; drahn@ ok | Michael Shalayeff | |
| 2004-05-25 | return object* the symbol is in for _dl_find_symbol*; drahn@ ok | Michael Shalayeff | |
| 2004-05-25 | spacing | Theo de Raadt | |
| 2004-05-24 | Change define used to deal with PLT protection, use postive logic not negative. | Dale Rahn | |
| ok mickey@ | |||
| 2004-02-10 | Check for RTLD_TEXT_PLT define instead of an architecture specific check. | Dale Rahn | |
| 2003-09-04 | Fix W^X mistake. If the dynamic linker is workin in non-lazy mode, it | Dale Rahn | |
| should still mprotect the GOT and PLT as appropriate. ok deraadt@ miod@ | |||
| 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@ | |||
| 2003-07-28 | The fifth argument to _dl_find_symbol is a 'int size', not a SYM_ define. | Dale Rahn | |
| Fix several calls which had the incorrect but working define in that position It happened that SYM_NOTPLT was 0, which was the desired size value. | |||
| 2003-07-09 | changes to ld.so to be compatible with newer binutils, requires | Dale Rahn | |
| slight changes in the startup code on most archs. ok art@ brad@ | |||
| 2003-07-06 | various proto, ansi, and knf repair. tested on all architectures that | Theo de Raadt | |
| use it. (build may require make cleandir because of .depend balony) | |||
| 2003-06-09 | pefo 3/4 licence cleanups | Theo de Raadt | |
| 2003-06-03 | three four gone. | Artur Grabowski | |
| 2003-06-03 | kill clause 3 and 4 from several of my copyrights, cleanup. | Dale Rahn | |
| 2003-05-30 | When loading a shared object or libraries dependant object, load them | Dale Rahn | |
| in random order. This will reduce the possiblity of a buffer overflow being able to predict the addresss of useful code. Can be disabled with the LD_NORANDOM environment variable for debugging purposes. ok deraadt. | |||
| 2003-04-28 | Change mquery() function call signature to be the same a mmap(). It | Dale Rahn | |
| needs the prot/flags info and passing the addresses via arg/return allows it to be traced via ktrace better than an in/out paramter. This adds a new mquery syscall and renames the old one to omquery. New kernel _MUST_ be built, booted, and 'make includes' before building ld.so with this change. | |||
| 2003-04-25 | backout mquery change, something broke when not combined with a different diff. | Dale Rahn | |
| 2003-04-25 | change mquery() function call signature to be the same a mmap(). It | Dale Rahn | |
| needs the prot/flags info and passing the addresses via arg/return allows it to be traced via ktrace better than an in/out paramter. This adds a new mquery syscall and renames the old one to omquery. New kernel _MUST_ be built and installed before building ld.so with this change. ok millert@ tedu@ | |||
| 2003-04-17 | mquery support, currently for i386 only. | Dale Rahn | |
| 2003-02-15 | After relocation is completed, remove write protection from GOT/PLT in ld.so. | Dale Rahn | |
| 2003-02-15 | Paranoia about mprotect, mprotect page aligned regions for got and plt. | Dale Rahn | |
| 2003-02-02 | knf & ansi; drahn ok | Theo de Raadt | |
| 2002-12-18 | Prepare for an upcoming ELF executable change. This will allow ld.so to | Dale Rahn | |
| protect the GOT and PLT sections of the executable from being overwritten. This behavior is enabled by changes in the executable/shared object layout, and does not occur without the ld changes. | |||
| 2002-11-23 | Put in a required item. Should not have been deleted to start with. | Dale Rahn | |
| 2002-11-14 | Make error messages on symbol lookup failures more useful. | Dale Rahn | |
| 2002-11-13 | Check for NULL on pltgot, appearently libraries with no external references | Dale Rahn | |
| will not create a PLT on i386. | |||
| 2002-10-25 | Some small fixes in MI code for mips backport. A new reloc md function, | Per Fogelstrom | |
| RELOC_GOT, was added to handle mips got bootstrap reloc. Also remove workaround used on previous versions of binutils for mips. | |||
| 2002-10-21 | Simplify the ld.so asm api, the data is available other ways. | Dale Rahn | |
| tested by naddy@ and myself. | |||
| 2002-09-01 | Make sure that the symbol return value is always initialized before | Dale Rahn | |
| the address of it is passed to dl_find_symbol(). fixes xpdf lazy binding problem. ok art@ | |||
| 2002-08-23 | Support for i386 ELF. Not an indication that the change is going to be made, | Dale Rahn | |
| just so that these files are maintained in the tree. | |||
