Bug reported by Arne Bernin <arne@alamut.de> in regards to freeswan.

Add $(PREFIX) to avoid leaking things at install time.

Hopefully locale support will build when cross compiling now. Collation is
still not supported, but that's what I'm currently working on. In the
next couple of days, I'll probably put up a couple of files for download
that will save people the trouble of generating all the glibc locales.
Added *wprintf functions, although they currently don't support floating
point. That will be fixed when I rewrite _dtostr... or possibly before.
Added the wcsto{inttype} functions.
Added iconv() and a mini iconv utility. The require locale support and
only provide for conversions involving the various unicode encodings
{ UCS-4*, UCS-2*, UTF-32*, UTF-16*, UTF-8 }, the 8-bit codesets built
with the locale data, and the internal WCHAR_T.

- Invert all FORCE_SHAREABLE_TEXT_SEGMENTS checks.
- Define FORCE_SHAREABLE_TEXT_SEGMENTS in the Makefile,
so it can be configured by the config system.
- linuxelf.h inspects that we don't combine FORCE_SHAREABLE_TEXT_SEGMENTS
and SVR4_BUGCOMPAT
- Add a new config option for FORCE_SHAREABLE_TEXT_SEGMENTS

I fixed two little bugs in ldso.c:
- For LDD support we test the old environment variable
LD_TRACE_LOADED_OBJECTS.
- Before we init the GOT table of the dynamic loader
we have to check, if we have a DT_PLTGOT entry.
If DT_PLTGOT was zero we patch somthing in the header
of the dynamic loader. This was the cause, why we have to
enable the DO_MPROTECT_HACKS option for all targets, to avoid
segment faults.
In readelflib1.c I added a warning, if we try to load a shared library, which
wasn't compiled with -fPIC or -fpic. So if we disable the DO_MPROTECT_HACKS
option we are sure, that we don't waste memory by shared libraries which
aren't able to share their text segment. I think this is a helpful option on
little embedded systems.

look into what is breaking dlclose() further...

unified syscall interface. I reworked his old patch considerably
and cleaned up his version of bits/syscalls.h with some sneaky macro
magic. And I implemented a powerpc correct version of pread/pwrite

I attached a patch, which revise the clone.S and vfork.S:
- Use PIC code.
- include new file syscall.S, so we can simply make a branch to
__syscall_error instead of a PLT/GOT call
- call errno_location to store the syscall error (for pthreads)
- avoid to use the 'shad' statement on SH2 targets
- call fork if vfork isn't available
- some cleanups and optimization

Hi Erik,
I added the FPU support for the setjmp/longjmp stuff.
This patch also moves the code from the bsd*.S files to the setjmp.S file, so
we can use simple branch instructions instead of referencing over the
.GOT/.PLT section. This makes the PIC code much easier, smaller and faster.
(The idea comes from the SPARC target)

since uclibc-0.9.16 I have to specify -fpic during _link_-time or else
I get an error from the dynamic linker when I load shared objects. Patch
is appended.
|
|
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.

This patch from David Meggy fixes it...
|
|
wide char support, even when the rest of uClibc was. This led
to anyone using regex segfaulting...

Ok, now i got it after a day of work.
I have had a look into glibc and found the following:
sysdeps/powerpc/dl-machine.c:
...
case R_PPC_JMP_SLOT:
/* It used to be that elf_machine_fixup_plt was used here,
but that doesn't work when ld.so relocates itself
for the second time. On the bright side, there's
no need to worry about thread-safety here. */
{
Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr;
...
The comment made me suspicious. The same position in uClibc looks like this:
ldso/ldso/powerpc/elfinterp.c:
...
case R_PPC_JMP_SLOT:
{
unsigned long targ_addr = (unsigned long)_dl_linux_resolve;
int delta = targ_addr - (unsigned long)reloc_addr;
...
When I change it to the following it works:
...
case R_PPC_JMP_SLOT:
{
unsigned long targ_addr = *reloc_addr;
int delta = targ_addr - (unsigned long)reloc_addr;
...
I hope it will not break anything. Can anyone review this change and
commit it into CVS?
thanks,
ron
