| 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 | |
| 2003-06-02 | nuke clause 3 & 4 | Jason Wright | |
| 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. | |||
| 2003-02-15 | 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 | Remove pointless 'if 0' code. | Dale Rahn | |
| 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 | After fixing these comments, I add another incorrect one. | Dale Rahn | |
| 2002-11-23 | Implement [u]mul/[u]div/[u]rem with faster version if available | Dale Rahn | |
| on machine. Improves speed for dynamic userland processes when active. Idea from Theo. ok deraadt@ | |||
| 2002-11-22 | Fix the comments on which systemcall is being processed, ok deraadt@ | Dale Rahn | |
| 2002-11-14 | Make error messages on symbol lookup failures more useful. | Dale Rahn | |
| 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 | 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. | |||
| 2002-08-21 | Split out MD makefile parts into separate files and do | Artur Grabowski | |
| some other cleanup in the Makefile. drahn@ ok. | |||
| 2002-08-12 | Add support for REL type relocations, all currently supported arch | Dale Rahn | |
| use only RELA type relocations, but that could change. ok art@ | |||
| 2002-08-11 | The parameter dynp was never used, rather than pass in a dummy on most | Dale Rahn | |
| archs and a nasty calcuation on others, remove the parameter. | |||
| 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. | |||
| 2002-08-09 | Various fixes. | Artur Grabowski | |
| - JMP_SLOT relocations require a symbol lookup (duh). - compress the nops to not dominate the code. - reorder the installation of the pltgot and always install it when possible. | |||
| 2002-08-08 | - Add some missing iflush's | Jason Wright | |
| - insert some nop's to make sure all copies are gone from the icache and CPU | |||
| 2002-07-29 | Bunch of cleanups and one last bugfix that seems to make things work. | Artur Grabowski | |
| Mark COPY relocations as needing to resolve the destination symbol. | |||
| 2002-07-27 | Commit work in progress before I get drunk tonight. | Artur Grabowski | |
| Code from sparc64 and NetBSD. Basically we can link the most, lazy linking works (!), but something else is screwed. | |||
| 2002-07-27 | Make self-relocation work. | Artur Grabowski | |
| 2002-07-27 | this is not sparc64. | Artur Grabowski | |
| 2002-07-27 | Stop being too creative, steal more code from sparc64. | Artur Grabowski | |
| 2002-07-27 | Just a skeleton for sparc. Builds, but pieces are missing and it doesn't | Artur Grabowski | |
| even get to dl_boot_bind correctly. | |||
