2004-08-09This should fix the dlsym problem Peter van Hoyweghen reported.Joakim Tjernlund
However RTLD_LOCAL still doesn't work. Everything is RTLD_GLOBAL.
2004-07-30Teach libdl to use normal libc symbols whenever possible, i.e. mallocEric Andersen
rather than _dl_malloc, fprintf rather than _dl_printf, etc. -Erik
2004-07-30Fix screwed up indentingEric Andersen
2004-07-16Revert this stuff for nowEric Andersen
2004-07-14Sigh. I got things working this morning, then checked stuff in from the wrongEric Andersen
tree. Bad boy, No doughnut. -Erik
2004-07-14Based on a patch from Alexandre Oliva, make sure _dl_malloc returns a nicelyEric Andersen
aligned pointer that may be aligned up to page_size. Also add _dl_free,
2004-05-13update libdl so it also groks the new _dl_errnoEric Andersen
2004-02-20Per discussion with Joakim Tjernlund, all the horrible weak declarations junkEric Andersen
in libdl pointing to the local 'foobar' function is garbage. This cleans all that up and makes the code much less horrible. Now it is only really really ugly (which is a marked improvement),

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 ...
2004-02-12Based on a problem report and patch from Florian Schirmer, fix a compileEric Andersen
problem with mips -- contrary to my expectation gcc on mips _always_ defines __PIC__ which breaks the assumption inherent in my code. This should fix things up.
2004-02-10Rework file naming, aiming for at least a vague level of consistancyEric Andersen
2004-02-07Thanks to Joakim's recent paches, we can now remove the FIXMEEric Andersen
2004-02-07Step one, begin shuffling things around a bitEric Andersen
2004-01-29Eliminate separate passes for _dl_copy_fixups() and _dl_fixup(), andEric Andersen
do both operations in a single pass.
2004-01-20As noted by Doru Petrescu, there was a spurious line that was usingEric Andersen
_dl_debug_addr prior to checking if it was NULL.
2004-01-16We need to link with libgcc.a when creating shared libs, in order toManuel Novoa III
avoid problems 'hidden symbol' problems. Also handle -lfloat for the soft-float arm case.
2003-11-04Rework the config system. Better utilize the Kconfig languageEric Andersen
which should simplify enabling arbitrary architectures. -Erik

ln.patch: * Define $(LN) as ln in Rules.mak. * Change all occurrences of ln into $(LN). * Change all constructs like (cd path && ln -sf foo/file file) into $(LN) -sf foo/file path/file. The latter construct is already used in a number of places so it should not be an additional compatibility problem.

rm.patch: * Define $(RM) as rm -f in Rules.mak and test/Rules.mak (this is the same definition as gmake uses by default). * Change all occurrences of rm and rm -f into $(RM).

install.patch: * Define $(INSTALL) as install in Rules.mak. * Change all occurrences of install into $(INSTALL). * Change all occurrences of mkdir -p into $(INSTALL) -d. install -d is already used in a number of places so this should not be an additional compatibility problem.
2003-10-15Doh! I was returning with an incorrect pointer type when dlopeningEric Andersen
already loaded libs, which unsurprisingly would cause dlsym() to not work at all... -Erik
2003-10-14Enable full debug support for ld-uClibc and libdlEric Andersen
2003-10-09When someone would dlopen a shared lib that was already opened,Eric Andersen
we would try to re-fixup the lib's relocations with rather horrible results. So fix that by checking the the dlopened lib has already had its init functions called, which will never be the case for newly loaded libs, and skip the rest in that case. also apply a few minor fixups
2003-09-02Fix a problem with dtors/dtors.Eric Andersen
2003-08-19I just realized we need global symbol resolution for everything inEric Andersen
a chain of dependent libraries or libraries that depend on other shared libraries will not work! So with a well placed dyn_chain->flags |= RTLD_GLOBAL; everything is now working perfectly!!! Sweet!!!! This patch also removes some leftover junk from my previous efforts.
2003-08-19Cool. Found most of the problem. Turns out we were inadvertanly loading someEric Andersen
libraries multiple times, wasting memory and causing different libraries to use different symbol sets, some of which were not properly resolved. Continue scrubbing ld.so and converting it to use proper types.
2003-08-19Phase one of my evil plan to clean up ld.so...Eric Andersen
2003-06-27Run dlopened ctors and dtors in the correct orderEric Andersen
2003-03-01doh. I forgot mips can't talk to globals that early on in theEric Andersen
process. Fix that up too. -Erik
2003-02-28Fix a potential compile errorEric Andersen
2003-01-28Stefan Allius noticed dlib_pic.o was not using XXFLAGS as it shouldEric Andersen
2003-01-03If they call dlopen with anything other than RTLD_LAZYEric Andersen
or RTLD_NOW then we need to error out.
2002-12-12Rework things such that staticly linked applications can useEric Andersen
dlopen and have it be successful. This required moving some things out of ldso.c into readelflib1.c, and directly including hash.c and readelflib1.c into dlib.c when building the static version of the library. -Erik
2002-11-15For now, revert Ronald Wahl's change to dlopen. We need toEric Andersen
look into what is breaking dlclose() further... -Erik
2002-11-15Ronald Wahl writes:Eric Andersen
I noticed that dlclose() does not work since libraries loaded with dlopen are not marked as "loaded_file". This breaks apache with dynamic modules. I append a small fix against uClibc-0.9.16.

2002-05-02Patch from Tobias Anderberg <tobias.anderberg@axis.com> toEric Andersen
remove the .asm calls
2002-05-02Patch from Steven J. Hill <sjhill@realitydiluted.com>:Eric Andersen
I am very pleased to announce that the MIPS dynamic linker/loader for uClibc is now working. It works on big and little endian platforms. A few minor changes were needed to avoid breaking ldd, and since this makes some non-trivial changes, I have tested on x86, arm, and powerpc to be sure thoese arches didn't get broken. Excellent work Steven!
2002-02-18Make shared libs properly list the correct ld.so in the interpEric Andersen
field by being sneaky.
2002-02-17Eliminate circular dependancyEric Andersen
2002-01-28Fix the bug where binaries built with older toolchains wouldEric Andersen
