2daff75bab sparc: Fix v9 memchr with long buffer lengths. 
test-memchr fails on 32-bit sparc with v9 optimized memchr because
it uses signed branch comparisons on the buffer pointers.

5c866a8b9b Fix PLT rewrite when prelinking fails on 32-bit sparc. 
When prelinking fails we have to rewrite the PLT, but the code
doing so forgets to adjust all rela->r_offset addresses by the
location of where the object was actually mapped.

1d204bf294 Fix PLT rewrite when prelinking fails on 64-bit sparc. 
When prelinking fails we have to rewrite the PLT, but the code
doing so forgets to adjust all rela->r_offset addresses by the
location of where the object was actually mapped.

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.

aa9890239a Optimize grantpt.

139ee080b6 Prevent unintended file desriptor leak in grantpt. 
The pt_chown program is completely transparently called.  It might
not be able to live with the various file descriptors the program
has open at the time of the call (e.g., under SELinux).  Close all
but the needed descriptor and connect stdin, stdout, and stderr
with /dev/null.  pt_chown shouldn't print anything when called to
do real work.

21f2c22320 Don't get tty group info multiple times in grantpt. 
This is a minor optimization.  The tty group mustn't change so a
successful call to getgrnam will always return the same information.
Cache it and reuse it.

eb4157390c Update ntp_gettime for Linux. 
The ntp_gettime implementation of NTP exports the tai field the kernel
now produces.  This requires an ABI change since the ntptimeval structure
changed.  Upstream kept the same name, there is nothing to do.  This
patch changes the ntptimeval structure but keeps the old ntp_gettime
definition.  A new ntp_gettimex function which is transparently invoked
through the old name is introduced.  This has the advantage that even
object files can remain compatible.  This wouldn't be the case if
symbol versioning would be used to overload the name ntp_gettime.

815d8147a3 Fix ranges with multibyte characters as endpoints. 
This is another bug in computing the fastmap.  It was reported by a user
of sed because it usually does not happen with !_LIBC.  However, it is
there in that case too.

The bug is that whenever we have a range at the beginning of the regex,
the regex must be tested on any possible multibyte character.  The reason
why _LIBC masks it, is that in general there is a collation symbol for
each possible multibyte-character lead byte, so all the lead bytes are
in general already part of the fastmap.

The tests use cyrillic characters as an example.  With _LIBC, they pass
without the patch too, but you can make them fail by removing collation
symbols handling.

as in dl-conflict.c sym_map is always NULL.  While dl-machine.h could use
RESOLVE_CONFLICT_FIND_MAP macro to compute it, it doesn't make sense,
because with prelink we know it is already properly relocated (all relative
relocations are applied by prelink).

tst-longjmp_chk passes, tst-longjmp_chk2 fails but that is because
of some limitations of kernel signal delivery on sparc that I need
to fix, it has nothing to do with the longjmp_chk implementation.

(The problem with tst-longjmp_chk2 is that it tries to do a stack
 fault SIGSEGV within a stack fault SIGSEGV , and the Linux kernel
 will refuse to setup the signal stack and deliver the signal if the
 register windows can't be written out to the stack first)

84088310ce Handle AVX saving on x86-64 in interrupted smbol lookups. 
If a signal arrived during a symbol lookup and the signal handler also
required a symbol lookup, the end of the lookup in the signal handler reset
the flag whether restoring AVX/SSE registers is needed.  Resetting means
in this case that the tail part of the outer lookup code will try to
restore the registers and this can fail miserably.  We now restore to the
previous value which makes nesting calls possible.

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.

a546baa9cd Properly count number of logical processors on Intel CPUs. 
The meaning of the 25-14 bits in EAX returned from cpuid with EAX = 4
has been changed from "the maximum number of threads sharing the cache"
to "the maximum number of addressable IDs for logical processors sharing
the cache" if cpuid takes EAX = 11.  We need to use results from both
EAX = 4 and EAX = 11 to get the number of threads sharing the cache.

The 25-14 bits in EAX on Core i7 is 15 although the number of logical
processors is 8.  Here is a white paper on this:

http://software.intel.com/en-us/articles/intel-64-architecture-processor-topology-enumeration/

This patch correctly counts number of logical processors on Intel CPUs
with EAX = 11 support on cpuid.  Tested on Dinnington, Core i7 and
Nehalem EX/EP.

It also fixed Pentium Ds workaround since EBX may not have the right
value returned from cpuid with EAX = 1.

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.

The test is probably too pessimistic.  All code linked into ld.so

faster SSE-using functions in parts of ld.so.

The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the

unlocked in one branch of the mempool_alloc() if.

I think unreproducible random assert(dh->usable) crashes in prune_cache() were

This patch adds SSSE3 strcpy/stpcpy. I got up to 4X speed up on Core 2

shorter (<64byte) data.

29ba9812bb Fix getnetbyaddr implementation. 
There were two problems in the getnetbyaddr implementation.  The type
argument is pretty much useless since (almost) no input file contains
this information and the NSS backends make up the value they fill in
for the n_addrtype field.  Therefore we now declare that passing AF_UNSPEC
is always recognized.  Secondly, the files backend didn't compare the network
numbers with the correct endianess.

Also change getent to take advantage of the type parameter change.

44d20bca52 Implement second fallback mode for DNS requests. 
There is some more shardware/software out there which has problems
if two DNS requests are sent using the same tuple

  (source addr, source port, dest addr, dest port)

This can range from firewalls to load balancers.  Some of the vendors
already fixed it in response to this problem.  Still, we need a way
to make glibc work with broken environments.  The single-request-reopen
flag can be used or we fall back automatically to this mode.

The check for the inclusion of a group in the result gave up too early

not blacklist we need not perform the check in the first place and
therefore can just accept the results of the initgroups_dyn callback.
