2004-08-27As Mike Frysinger notes, this code is still needed. IJoakim Tjernlund
misread this code and removed it, sorry. I printed the values of _dl_brkp and _dl_envp in ldso and got this when executing: ls: __curbrk: 0x300c16e0 __environ: 0x1008372c ldd: __curbrk: 0x300776e0 __environ: 0x3007759c why is__environ in the app when executing ls but not ldd?

2004-08-26Partial patch from Alexandre Oliva:Eric Andersen

2004-08-26Let ldso find libc's malloc function and set _dl_malloc_function.Joakim Tjernlund
This removes some crap in libdl.c(and future libs which needs to access ldso functions). What do you think?
2004-08-26Added test for RTLD_GLOBAL flag in _dl_find_hash().Joakim Tjernlund
Fixed a bug in libdl.c where the RTLD_GLOBAL was assigned wronly.
2004-08-26Relocations of the application's global GOT entries were not being run, andEric Andersen
only the global GOT entry relocations for the loaded shared libs were being handled. This made applications segfault when using un-fixedup symbols. After many hours debugging to track down the problem, this patch makes the mips port happy again. -Erik

"I fixed the _dl_parse_copy_information in the same way than for the powerpc and it works fine for me. You may luck at the patch for the powerpc/elfinterp.c, where I change the paramter of a dl_dprintf statement. Now we use the same parameters than for the relocation copy." Arch mantainers, please do the same. When all arches has been fixed, we can remove of _dl_parse_copy_information, it is just a waste of CPU cycles.

this was sent earlier in a different form: http://www.uclibc.org/lists/uclibc/2004-January/008136.html find attached a smaller version ... perhaps adding a fprintf to stderr before calling abort would be nice like in the glibc patch, but whatever glibc has since adopted a similar fix for their malloc (third hunk, line 1970) http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/malloc/malloc.c.diff?r1=1.121&r2=1.122&cvsroot=glibc&f=h -mike

i sent this earlier but perhaps people missed it the first time around :) http://www.uclibc.org/lists/uclibc/2004-August/009544.html basically if you try to #include <sys/ucontext.h> on arm it'll fail because ucontext.h utilizes typedefs found in bits/sigcontext.h ... i386 already has this fix in uClibc find attached a trivial patch to fix this -mike

Hi Manuel & Erik I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is broken. It will due to my latest changes reloctate ldso. This function needs to die and its job should be done inside _dl_parse_relocation_information(). It is mostly a copy and paste job, Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they use symbols which aren't passed as arguments. Jocke
2004-08-25Patch by Carl SHAW <carl.shaw@st.com>...Manuel Novoa III
Below is a patch to make the pread and pwrite calls work on the SH architecture. I've only tested this on the SH4 with a 2.4.24 kernel - a fairly recent kernel is required as the problem is partially fixed in the kernel itself. For more information (in relation to glibc, but the problem is the same) see the thread at http://sourceforge.net/mailarchive/message.php?msg_id=2375908 Someone should really test this on the SH2/3...
2004-08-25Patch from Stefan Allius:Joakim Tjernlund
Remove unused function parameter in ldso. Remove echo option '-e' since it is not supported on Solaris.
2004-08-25Hopefully fix Laszlo and Jacobs dlopen problem.Joakim Tjernlund

TODO item is now done.
2004-08-21Attempt to support 'gcc -finstrument-functions', which seems muchEric Andersen
more sane than 'gcc -pg' and seems much easier to support. -Erik
2004-08-21Kill off all support for 'gcc -pg' / 'gprof' style profiling. There is both aEric Andersen
size and performance penalty to profiling applications this way, as well as Heisenberg effects, where the act of measuring changes what is measured. There are better tools for doing profiling, such as OProfile, that do not require gcc to instrument the application code. -Erik

2004-08-18Clean up the _dl_boot code and make it similar to arm and sh.Joakim Tjernlund
2004-08-17Carl SHAW writes:Eric Andersen
I finally tracked down the problem with SH4 shared library loading - in file ldso/ldso/sh/dl-startup.h, the line #define DL_BOOT(X) static void __attribute_used__ _dl_boot2 (X) should be #define DL_BOOT(X) static void* __attribute_used__ _dl_boot2 (X) otherwise the application code will never be called and _dl_boot will just return causing a segmentation fault.

"There's a bug in the SH asm, it calls into 'C' code without preserving all the important scratch registers. I have been meaning to double check the changes as I think more registers need to be saved, then I was going to send it back to uClibc. From the sound of it this isn't your problem, but you never know. Attached is the patch as it stands for the loader on SH." Glibc appears to do the same.
2004-08-17Let ldso decide if it should relocate itselft a second time. ThisJoakim Tjernlund
is needed if ldso should use libcs malloc whenever possible. Fix RTLD_LAZY propagation to RTLD_NOW relocation when requested by libdl.
2004-08-17Fix make clean rule.Joakim Tjernlund

2004-08-16Setup __pagesize from inside __uClibc_init(), or else when registeringEric Andersen
dtors via atexit(), atexit may need to call realloc with __pagesize still set to 0. ugh. -Erik
2004-08-16Be a bit more prominant about the fact that setuid handlingEric Andersen

2004-08-16The variable used to store pagesize is not the same as theEric Andersen
_dl_pagesize variable in ldso, so avoid aliasing. -Erik
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

return the length and the actual dns packet as received, rather than making stuff up. -Erik
