Corrects libpthread_db name (I do not know why libpthread_db.so uses
libpthread_db.so.1 instead of libpthread_db.so.$(MAJOR_VERSION) as soname)

Note by Jocke:
I don't known either but until then this is the right thing to do.

Don't complain if ld.so.cache is missing.

Add type libc0 to cache_print().
Always strip trailing slaches(/) from paths read from ld.so.conf.

Hello!

Here is the modified unsecvars patch that applies to cvs.

Puts common defines into dl-defs.h (in ldso/include) from dl-elf.h and
dl-cache.h and make use of it. Also disables the lib-path-redundancy check
for the case the cache is not used. Makes use of _PRELOAD_FILE_SUPPORT.
From Peter Mazinger.

Remove unneeded -D<somedefine>, and use instead #ifdef __somedefine__
From Peter Mazinger.

PIE option correction for Config.in. From Peter Mazinger.

After the addition of a configuration option for
enabling the support of /etc/ld.so.cache, I thought
it might be a good idea to add one for the support
of the /etc/ld.so.preload file too. So here it is.

While doing this, I also noticed that the dynamic
linker would hang indefinitely if either LD_PRELOAD
or /etc/ld.so.preload contained a library which was
already loaded, so I made a patch for that too.

And of course, I could not resist from doing a little
clean up of comments and indentation, so here is a
patch for that too.

This patch from Mike Frysinger, extended from an earlier patch from Peter S.
Mazinger implements the changes suggested by me on the uclibc list.

Hi. I found a mismatch between uClibc and kernel in semctl definition.

In uClibc/libc/misc/sysvipc/sem.c:

static inline _syscall4(int, __semctl, int, semid, int, semnum, int, cmd, union semun *, arg);
...
int semctl(int semid, int semnum, int cmd, ...)
...
arg = va_arg (ap, union semun);
...
return __semctl(semid, semnum, cmd, &arg);

But kernel's semctl is:

asmlinkage long sys_semctl (int semid, int semnum, int cmd, union semun arg)

The last argument is an union semun itself, not a pointer to the
union.

Here is a patch.

Oops, typo.
Thanks to Peter Kjellerstedt.

Remove /usr/X11R6/lib from search path.
Search in UCLIBC_RUNTIME_PREFIX"lib" before
UCLIBC_RUNTIME_PREFIX"usr/lib".

X11 users should enable USE_CACHE in Rules.mak, add
/usr/X11R6/lib to /etc/ld.so.conf and run ldconfig.

Make ldd work for ET_DYN executables. From Peter Mazinger.

Remove /usr/X11R6/lib from default list.
Move /lib and /usr/lib first in ld.so.cache.
Ignore duplicate /lib and /usr/lib in ld.so.conf

Add bswap_64 macro and uClibc_page.h. From Peter Kjellerstedt.

Don't allow undefined global symbols to pass.
Move COPY relocs back to _dl_do_reloc().
White space cleanup.

White space and printouts cleanup. From Peter Kjellerstedt.

Make do_rem() safe. From Peter Kjellerstedt.

Don't allow undefined global symbols to pass.
Move COPY relocs back to _dl_do_reloc().

Make powerpc look more like the other archs.

Added back dl_iterate_phdr in ldso(with some small changes).
Someone needs to test if it works to build and run gcj.

Formatting cleanups from Peter Kellerstedt.

Bugfix: Add r_addend to final address. The r_addend is mostly zero
but can be nonzero for JMP relocs as well.
All Rela arches need to do this, test and send a patch :)

Remove unneeded test in R_PPC_COPY.

Don't allow undefined global symbols to pass(all archs needs fixing,
but powerpc).
If you are using buildroot and soft floating point, you may have to
rebuild the libm.so library, copy it to staging_dir/lib and rebuild
your application.

Move handling of R_386_COPY back into _dl_do_reloc(all archs should
do this). Adjust the first argument to _dl_memcpy as it looks wrong
to have symtab[symtab_index].st_value as destination for the mem copy.

Don't allow undefined global symbols to pass(all archs needs fixing).
If you are using buildroot and soft floating point, you may have to
rebuild the libm.so library, copy it to staging_dir/lib and rebuild
your application.

Cleanups as well.

Hide some x86-specific devel asserts.

Fixup URL

Second attempt to fix the INIT/FINI order. This time I think I got it right :)
This needs testing with apps that have complex dependencies.
