d7dd44133f Fix ld.so regression. 
[BZ #13967]
	* elf/dynamic-link.h (_ELF_DYNAMIC_DO_RELOC): Handle the case
	where the is a gap between DT_REL(A) and DT_JMPREL.

73d65cc378 New ld.so argument --inhibit-ldcache to disable ld.so.cache lookup 
It may sometimes be desirable to make the dynamic linker only pick up
libraries from the library path and rpath and not look at the
ld.so.cache that ldconfig generates. An example of such a use case is
the glibc testsuite where the dynamic linker must not be influenced by
any external paths or caches.

This change adds a new option --inhibit-ldcache that when used, tells
the dynamic linker to not use ld.so.cache even if it is available.

e453f6cd0c Fix potential problem with skipping relocations 
We never seem to have hit this problem but way relative relocations
were skipped was wrong.  There are relative relocations only in the
DT_REL/DT_RELA section.  The elf_dynamic_do_##reloc function skipped
the entries in all calls, though.

d26dfc60ed Fix handling of static TLS in dlopen'ed objects 
When dynamically loading a library along with several dependencies, calls to
_dl_add_to_slotinfo and _dl_update_slotinfo can become intermixed. As a
consequence, _dl_update_slotinfo will update the generation counter of the dtv
although not all of the slots belonging to that generation have been added.
Subsequent calls to _dl_add_to_slotinfo will add more slots to the same
generation, for which no storage will be allocated, as the dtv generation
checks will claim no work is necessary. This will lead to uninitialized dtv
entries and will likely cause a SIGSEGV when thread local variables are
accessed.

6db52fbb27 Allow aux_cache_file open()ing to fail silently even in the chroot mode. 
The aux_cache fix of bug 11149 introduced a new bug - normally,
ldconfig -r never cares if the auxiliary cache is not available and
that is not a fatal problem, however this is not the case in case
of ldconfig -r when executed as non-root. In that case, ldconfig -r
fails hard unless var/cache/ldconfig/ exists within the chroot. This
patch fixes that.

3a56ea2673 ld.so: Adjust the auxv if ld.so is directly invoked. 
If a binary gets invoked by passing it as argument to ld.so the stack
still holds the auxiliary vector of ld.so when entering the _start
routine of the executable.  So the invocation via ld.so is not fully
transparent to the executable.  This causes problems if the executable
wants to scan the auxv itself.

This patch fixes mixed SSE/AVX audit and checks AVX only once in
_dl_runtime_profile. When an AVX or SSE register value in pltenter is
modified, we have to make sure that the SSE part value is the same in both
lr_xmm and lr_vector fields so that pltexit will get the correct value
from either lr_xmm or lr_vector fields. AVX-enabled pltenter should
update both lr_xmm and lr_vector fields to support stacked AVX/SSE
pltenter functions.

b48a267b8f Preserve SSE registers in runtime relocations on x86-64. 
SSE registers are used for passing parameters and must be preserved
in runtime relocations.  This is inside ld.so enforced through the
tests in tst-xmmymm.sh.  But the malloc routines used after startup
come from libc.so and can be arbitrarily complex.  It's overkill
to save the SSE registers all the time because of that.  These calls
are rare.  Instead we save them on demand.  The new infrastructure
put in place in this patch makes this possible and efficient.

09cd1f5754 Fix STB_GNU_UNIQUE handling for > 30 unique symbols. 
There were several issues when the initial 31 entries hashtab filled up.
size * 3 <= tab->n_elements is always false, table can't have more elements
than its size.  I assume from libiberty/hashtab.c this meant to be check for
3/4 full.  Even after fixing that, _dl_higher_prime_number (31) apparently
returns 31, only _dl_higher_prime_number (32) returns 61.  And, size
variable wasn't updated during reallocation, which means during reallocation
the insertion of the new entry was done into a wrong spot.

All this lead to a hang in ld.so, because a search with n_elements 31 size
31 wouldn't ever terminate.

415ac3df9b Implement STB_GNU_UNIQUE handling. 
Some symbols have to be identified process-wide by their name.  This is
particularly important for some C++ features (e.g., class local static data
and static variables in inline functions).  This cannot completely be
implemented with ELF functionality so far.  The STB_GNU_UNIQUE binding
helps by ensuring the dynamic linker will always use the same definition for
all symbols with the same name and this binding.
