PPC32, SPARC32/64 and S390 includes the PLT in its RELA size. This caused ldso to always do unlazy relocation of the JMPRELs. This patch fixes it.

This patch makes -fpic work for PCC and optimzes the relcation by moving the cache flushing stuff to JMP relocs only. Actually PPCs ldso can only handle small GOT tables(<=8192 entries)anyhow, so it makes little sense to compile PPC with -fPIC. libuClibc shrunk from 340724 to 330780 bytes with -fpic.

Some utilities, such as valgrind, have a legitimate reason to know the address of the current brk. Since we know such utils will peek under our skirt, we might as well give them what they expect and not use a gratuitously different symbol name. -Erik

Hi Erik, I'm not sure why the NIOS support is not in uClibc -- perhaps the patch was rejected or never submitted? In any case, I'm playing with some NIOS stuff and created this patch against 0.9.26. The work was done by Microtronix. I'm not sure who else contributed to it. It would be great to have the NIOS support available in uClibc so developers don't have to go searching for these bits. Pete

This is a patch for uClibc/libc/sysdeps/linux/mips/sys/procfs.h pulled from glibc CVS. This fixes gdb with threaded application (with glibc environment). Although debugging threaded programs seems not working on uClibc/mips yet, this patch will be required when it becomes working. This patch can be applied to any version of uClibc (including current CVS).

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.

Since MIPS don't have COPY relocs it seems apropiate to define DL_NO_COPY_RELOCS. This will optimize dl_find_hash somewhat.

dl-string.h references do_rem, but do_rem is a #define in <arch>/dl-sysdep.h which is not included by dl-sysdep.h. This causes a problem in libdl: In file included from ../../ldso/include/ldso.h:27, from libdl.c:33: ../../ldso/include/dl-string.h: In function `_dl_simple_ltoa': ../../ldso/include/dl-string.h:216: warning: implicit declaration of function `do_rem' Include dl-sysdep.h in dl-string.h before using do_rem.

Rather than copy more code back into the bridge-utilities, how about applying this change to uClibc? I hate when packages get cluttered for workarounds for other incompatibilities. The problem is that SIOCGIFCONF only lists interfaces that have IP addresses, so it doesn't find the other interfaces that are being used for bridging. It could be fixed in the kernel to return all interfaces, but then something else might break; and still it mean a kernel update for the 2.4 users. The whole use of ifindex in the bridge API is a bad idea. But we probably have to live with it for compatibility. Patch against uClibc 0.9.26

Hello, I managed to get ldso (and thus shared linking to uClibc) to work on sparc (actually sparc64 kernel with 32-bit userspace), at least on simple "hello world" program (more complex ones not tested). Some notes on attached patch (against 0.9.26, would require some work to apply on current CVS - but I tested 0.9.26, not CVS): - ELF magic cannot be examined by _dl_strncmp so early, probably because of string constant, like on ppc/mips/sh (note that early SEND_STDERR still crashes when trying to do _dl_strlen - I suppose that string constants require relocation; but adding load_addr didn't help, just ELF header was displayed instead of crash) - mmap() is syscall6 like on ppc/mips/sh, not old i386 mmap() - for generic sparc (i.e. not sparcv8/sparcv9) gcc produces .udiv/.urem calls for unsigned integer / and % operators - so these operations must be avoided. I copied do_rem definition from arm header. But / and % are used also in _dl_simple_ltoa() and _dl_simple_ltoahex(); in ltoahex gcc optimizes it to shifts (but I think it's safer to use shifts explicitly, not rely on optimization...). I changed % in ltoa to do_rem, but as there was no do_div definition, I changed all "%d" specifiers to "%x" to avoid crashes (this changes wouldn't be needed if _dl_simple_ltoa() were fixed to not use division on sparc). - "#define SOLARIS_COMPATIBLE" in ld_sysdep.h broke ldso on Linux because of redefining _dl_linux_resolve only in some places (it was still referenced in INIT_GOT before redefinition). So _dl_linux_resolve redefinition should be moved before INIT_GOT definition or removed. - sparc64 kernel requires mmap() addresses to be aligned to 8192, not 4096, otherwise mmap() call failed - reloc_entry must be shifted by 10, not 12 (I found similar operation in glibc sources) Aside of sparc-specific fixes: - I moved some _dl_dprintf()s inside if(_dl_debug_*) conditions (to avoid debugging messages when LD_DEBUG is not defined) - it seems that there was possible off-by-one in ltoa and ltoahex? they are called with char[22] as 1st argument, and then '\0' is stored in local[22] (_before_ p decrementation)... or am I missing something? If not, fix is included in patch.
