2005-06-27Add __libc_stack_end to ld.so. The libc.a version remains to do.Joakim Tjernlund
sjhill, feel free to comment :)
2005-06-25create some DEBUG macros for the ld debug earlyMike Frysinger
2005-04-13Adjust indentationEric Andersen
2005-04-13This update gets mips working again.Eric Andersen
2005-04-12Remove __FORCE_SHAREABLE_TEXT_SEGMENTS__ hack from ldso itself.Joakim Tjernlund
2005-03-29Moved the addition of load address from the fast pathJoakim Tjernlund
where possible. This will also make ldso smaller. However the patch touches all archs and I have only tested PPC and x86.
2005-03-18Remove dead code.Joakim Tjernlund
2005-03-17General arch cleanup and prepare support for standaloneJoakim Tjernlund
execution of ldso. Added new asm for MIPS to be tested. All arches should retest.
2005-03-14Generalize optimized relative reloc procesing.Joakim Tjernlund
Add elf_machine_dynamic() and elf_machine_load_address() for all archs. elf_machine_dynamic() replaces the #ifdef mess to get at the GOT. elf_machine_load_address() is needed to execute ldso directly, this is not complete yet. I probably broke one or two archs(only tested PPC) so please try and report problems. For a report to be useful you need to enable __SUPPORT_LD_DEBUG_EARLY__ and __SUPPORT_LD_DEBUG__
2005-01-12Use the inlined __dl_parse_dynamic_info() in DL_BOOT() for CRIS too.Peter Kjellerstedt

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.
2004-10-06Remove unneeded -D<somedefine>, and use instead #ifdef __somedefine__Joakim Tjernlund
From Peter Mazinger.
2004-08-19Accunt for ELF_MACHINE_PLTREL_OVERLAP when relocating ldso.Joakim Tjernlund
2004-08-19Remove poor man's malloc. Not needed anymore.Joakim Tjernlund
2004-08-19Move "debug_addr" ptr from dl-startup.c to ldso.cJoakim Tjernlund
2004-08-19Move the app specific stuff from dl-startup.c to ldso.c.Joakim Tjernlund
2004-08-19Oops, forgot to remove unused variable.Joakim Tjernlund
2004-08-19This is now done in ldso.cJoakim Tjernlund
2004-08-16The pagesize variable used when starting up is _not_ the sameEric Andersen
as the _dl_pagesize global, so do not alias the global. -Erik

Hi yet again :) in dl-startup.c when performing boot strap relocation the following test exists to make sure that only "_dl_" symbols are relocated: /* We only do a partial dynamic linking right now. The user is not supposed to define any symbols that start with a '_dl', so we can do this with confidence. */ if (!symname || !_dl_symbol(symname)) { continue; } However on PPC(and the other archs as well I suspect) all symbols are "_dl_" symbols so the test is never true. The test can be removed and the whole loop simplified(smaller). This also makes it possible to simplify elfinterp.c This remove the scanning of ldso.so relocs, making relocation faster. I have tested this on PPC and it works well. Do you think this optimization will work for the other arches as well? I can't see why not. Jocke * Tested on x86, arm, mipsel, and powerpc by Erik and works nicely -Erik

Oops, this adds the page alignment offset to the mprotected size. Regards, Brad
2004-05-12Patch from Bradley D. LaRonde:Eric Andersen
ld.so mprotect rwx .dyanmic segment for mips DT_DEBUG Allow writing debug_addr into the .dynamic segment. Even though the program header is marked RWE, the kernel gives it to us rx.
2004-05-11As noticed by the sharp eyed Joakim Tjernlund, I stupidlyEric Andersen
hard coded 4096 instead of PAGE_SIZE. Because I'm an idiot.
2004-05-11make certain that getpagesize() returns correct the value for mipsEric Andersen
by extracting the value from the ELF header.
2004-02-17Kill off an arm specific hack, that fostered three other arch specificEric Andersen
hacks. Just check for the elf magic string one byte at a time....
2004-02-17When doing _dl_mmap to obtain a bit of anonymous memory, use a much moreEric Andersen
sensible -1 fd, rather than pretending to work off of fd 0, which makes absolutely no sense.

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 ...
2004-02-10Eliminate the PIE support option, and simply support that all the timeEric Andersen
2004-02-10Rework file naming, aiming for at least a vague level of consistancyEric Andersen
2004-02-08Cleanup whitespace and formattingEric Andersen
2004-02-07Restore the library entry point so it works. It does haveEric Andersen
to be arch specific to work properly.
2004-02-07Split off the stuff that cannot use function into its own file,Eric Andersen
to make it easier to treat it specially while not bothering the rest of the code with the same constraints.
