(1) in pthread_create:
If the one signal is received before esp is subtracted by 16 and
__thread_entry( ) is called, the stack will be cleared by kernel
when it tries to contruct the signal stack frame. That will cause
that __thread_entry will get a wrong tls pointer from the stack
which leads to the segment fault when trying to access tls content.
(2) in pthread_exit
After pthread_exit called system call unmap(), its stack will be
freed. If one signal is received at that time, there is no stack
available for it.
Fixed by subtracting the child's esp by 16 before the clone system
call and by blocking signal handling before pthread_exit is started.

__atomic_cmpxchg and other related atomic operations did not
provide memory barriers, which can be a problem for non-platform
code that links against them when it runs on multi-core devices.
This patch does two things to fix this:
- It modifies the existing implementation of the functions
that are exported by the C library to always provide
full memory barriers. We need to keep them exported by
the C library to prevent breaking existing application
machine code.
- It also modifies <sys/atomics.h> to only export
always-inlined versions of the functions, to ensure that
any application code compiled against the new header will
not rely on the platform version of the functions.
This ensure that said machine code will run properly on
all multi-core devices.
This is based on the GCC built-in sync primitives.
The end result should be only slightly slower than the
previous implementation.
Note that the platform code does not use these functions
at all. A previous patch completely removed their usage in
the pthread and libstdc++ code.
+ rename arch-arm/bionic/atomics_arm.S to futex_arm.S
+ rename arch-x86/bionic/atomics_x86.S to futex_x86.S
+ remove arch-x86/include/sys/atomics.h which already
provided inlined functions to the x86 platform.

We're going to modify the __atomic_xxx implementation to provide
full memory barriers, to avoid problems for NDK machine code that
link to these functions.
First step is to remove their usage from our platform code.
We now use inlined versions of the same functions for a slight
performance boost.
+ remove obsolete atomics_x86.c (was never compiled)
NOTE: This improvement was benchmarked on various devices.
Comparing a pthread mutex lock + atomic increment + unlock
we get:
- ARMv7 emulator, running on a 2.4 GHz Xeon:
before: 396 ns after: 288 ns
- x86 emulator in KVM mode on same machine:
before: 27 ns after: 27 ns
- Google Nexus S, in ARMv7 mode (single-core):
before: 82 ns after: 76 ns
- Motorola Xoom, in ARMv7 mode (multi-core):

For Honeycomb, we added proper file thread-safety for
all FILE* operations. However, we did implement that by
using an out-of-band hash table to map FILE* pointers
to phtread_mutex_t mutexes, because we couldn't change
the size of 'struct _sFILE' without breaking the ABI.
It turns out that our BSD-derived code already has
some support code to extend FILE* objects, so use it
instead. See libc/stdio/fileext.h
This patch gets rid of the hash table, and put the
mutex directly into the sFILE extension.

The old code didn't work because the kernel expects a 64-bit sigset_t
while the one provided by our ABI is only 32-bit. This is originally
due to the fact that the kernel headers themselves define sigset_t
as a 32-bit type when __KERNEL__ is not defined (apparently to cater
to libc5 or some similarly old C library).
We can't modify the size of sigset_t without breaking the NDK ABI,
so instead perform runtime translation during the call.

There are three changes of note - most urgently, Cuba (America/Havana)
has extended summer time by two weeks, now to end on Nov 13, rather than
the (already past) Oct 30. Second, the Pridnestrovian Moldavian Republic
(Europe/Tiraspol) decided not to split from the rest of Moldova after
all, and consequently that zone has been removed (again) and reinstated
in the "backward" file as a link to Europe/Chisinau. And third, the
end date for Fiji's summer time this summer was moved forward from the
earlier planned Feb 26, to Jan 22.
Apart from that, Moldova (MD) returns to a single entry in zone.tab
(and the incorrect syntax that was in the 2011m version of that file
is so fixed - it would have been fixed in a different way had this
change not happened - that's the "missing" sccs version id).

vfork() would not save the registers that the parent would expect
to have restored after execl() completed.
Specially that execl() would call execve() underneath, further messing
up the stack of the parent.
To avoid that, we fork() for now. Later we will revisit and cleanup
vfork()+execve() to actually have vfork() store all the register
that the parent expects to see, and not those left by execve().
In the original code, looking at the registers just before the call to
popen(), and after the call showed that r7 would get clobbered.
This would leave the caller with an invalid pointer, leading to all
kinds of data corruptions.
execve() is simpler that execl() in this case.

This patch changes the declaration of size_t on x86 targets
to test for the __ANDROID__ macro, instead of ANDROID
__ANDROID__ should be a builting toolchain macro, while ANDROID
is usually added manually during the build.
Testing against __ANDROID__ allows us to use the header when
using the NDK's standalone x86 toolchain.
This is related to http://code.google.com/p/android/issues/detail?id=19011
The bug was already fixed in the NDK platform headers, this simply updates
the C library one accordingly.

Our dlmalloc implementation currently calls abort() when it detects
that the heap is corrupted, or that an invalid pointer is passed to
one of its functions.
The only way to detect this is because abort() will force-fully
crash the current program with a magic fault address of '0xdeadbaad'.
However, this is not really well documented, and a frequent topic
on the android-ndk forum (among others).
This change makes our dlmalloc code dump a simple message to the
log just before the abort() call (and hence before the stack trace)
to better help identify the problem.

NOTE: This is a back-port from the internal HC branch.
This patch fixes a leak that occurs when creating a new
thread-specific DNS resolver state object.
Essentially, each thread that calls gethostbyname() or getaddrinfo()
at least once will leak a small memory block. Another leak happens
anytime these functions are called after a change of the network
settings.
The leak is insignificant and hard to notice on typical programs.
However, netd tends to create one new thread for each DNS request
it processes, and quickly grows in size after a > 20 hours.
The same problem is seen in other system processes that tend to
create one thread per request too.
The leak occured becasue res_ninit() was called twice when creating
a new thread-specific DNS resolver state in _res_get_thread().
This function could not properly reset an existing thread and was
leaking a memory block.
The patch does two things:
- First, it fixes res_ninit() to prevent any leakage when resetting
the state of a given res_state instance.
- Second, it modifies the _res_get_thread() implementation to
make it more explicit, and avoid calling res_ninit() twice
in a row on first-time creation.

All the other property stuff is already here. Property setting was
only in libcutils previously to leverage a utility function / constant
or two.
Unfortunately in the process of fixing a race condition we would've
had to do break abstraction boundaries and put some libc-internal
details into libcutils so instead of that we'll just move this
into bionic.

libc: <stdint.h>: Don't make __STD_CONSTANT_MACROS available if only __STD_LIMIT_MACROS is defined.
This patch prevents the definition of various macros when <stdint.h> is
included from C++. The ISO C99 standard mentions that when this header
is included from a C++ source file, limit and constant related macros
should only be defined when asked explicitely by defining
__STDC_LIMIT_MACROS and __STD_CONSTANT_MACROS, respectively.
The <stdint.h> lacked the proper #ifdef .. #endif blocks for the
following macros:
INTPTR_MIN, INTPTR_MAX, UINTPTR_MAX, PTRDIFF_MIN, PTRDIFF_MAX
INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX,
INPTR_C, UINTPR_C, PTRDIFF_C, INTMAX_C, UINTMAX_C
This is intended to fix http://code.google.com/p/android/issues/detail?id=14380

Fix the handle locking in stdio to use flockfile/funlockfile
internally when and where required. Macros in <stdio.h> are updated
to automatically call the underlying functions when the process is
threaded to obtain the necessary locking. A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization. Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

Make the scripts use external/kernel-headers/original by default.
clean_header.py: Document -k<path>, add -d<path>
find_headers.py: Make kernel config files optional
update_all.py: Allow setting the path to kernel headers on the command-line
update_all.py: Better formatting of output on ttys
update_all.py: Automatically perform "git add/rm" on affected files.
SYSCALLS.TXT: Fix typo in __socketcall definition.
checksyscalls.py: Add support for superH architecture in the checks.
gensyscalls.py: Automatically perform "git add/rm" on affected files.
cpp.py: Fixed a bug that prevented certain type definitions to
be kept in the generated clean header (e.g.
struct ethtool_drvinfo in <linux/ethtool.h>)
All scripts will use the content of external/kernel-headers/original by default now.
The generated code removes all empty lines and trailing whitespace. This is useful
to ensure a unified output even if we change the parser again in the future.
The top-level disclaimer has been edited with update instructions to regenerate
the headers when needed.
Also, a warning is now inserted every 8th line in the final output:
/* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */
Changes under kernel/arch-arm and kernel/arch-x86 should correspond to whitespace
differences and additionnal struct definitions that were missed by the previous
parser implementation.

WARNING: If you run these script, do not submit the result to gerrit for now.
It seems there are discrepancies between the content of original headers
and those currently commited under bionic/libc/kernel/.
(This problem is the main motivation to insert the warning repeatedly).
Current list of issues:
- Missing SuperH headers (i.e. external/kernel-headers/original/asm-sh)
On ARM there is currently no assembler optimized memmove in libc.
There is however a more optimized bcopy which copies long instead
of bytes where possible. This almost doubles the performance in
best case.

* changes:
Add icmp6.h and ip6.h files from current NetBSD libc.
Include the Linux ipv6.h header from netinet/in.h, to get things like in6_pktinfo.
Add IN6ADDR_LOOPBACK_INIT macro to <netinet/in6.h>, as the kernel headers do not provide it anymore.
Update IPv6 kernel headers with new 2.6.37 headers, cleaned by update_all.py. (It wanted to do many other changes, most of them cosmetic, but I only included the IPv6 changes.)
Fix syntax error in defaults.py.
Use the the TTL of the answer as the time a query
shall remain in the resolver cache.
Added some debugging support as well, i.e.
parse answer and print a la dig.

This patch moves the definition of struct user_vfp from <asm/ptrace.h>
to <asm/user.h> for the ARM platform, in order to match the original
kernel headers.
See patches 94519 and 94520 for a description of the problem and a
fix for debuggerd that uses the structure.
This prevented us from properly re-running the kernel headers cleanup
scripts.

Implement RFC3484 policy table changes from draft-ietf-6man-rfc3484-revise-01.
The changes in a nutshell:
- Handle v4-mapped as different from v4-compat (this was probably
an existing bug in our code).
- Add policy entries for ULA, above most everything else.
- Put v4-compat, old-style IPv6 site-local and 6bone addresses
way down in the preference table.
The rest is just shuffling numbers around (no actual changes to
priority).

Add a new #define IN6_IS_ADDR_ULA, for testing for Universal Local IPv6 Unicast addresses (ULAs). These replace the old site-local IPv6 addresses.

Don't treat private IPv4 addresses as being in a non-global scope. The effect of this change is essentially to prefer NATed IPv4 over 6to4.

After this change, SIGRTMAX will be set to 64 (instead of 32 currently).
Note that this doesn't change the fact that our sigset_t is still defined
as a 32-bit unsigned integer, so most functions that deal with this type
won't support real-time signals though.

This patch improves the handling of 64-bit parameters in syscalls on ARM.
The ARM EABI mandates that 64-bit quantities be passed in even/odd register
pairs, which requires special treatment.
This allows us to simplify our implementations of pread() and pwrite()
and remove the C stubs for pread64() and pwrite64().
Also add ftruncate64() to <unistd.h>

asm() conflicts with userland code compiled with -std=c99, the userland
libc should only use __asm__() instead. Therefore, this transformation
has to be applied to all exported headers.
This only changes arch-arm/asm/byteorder.h.

If compiling userland code with -std=c99, the current header produces an
error. The content of this header originally is a kernel internal header,
where asm() is acceptable. In a header visible to userland, this should be
__asm__ instead.
