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).

AI_ADDRCONFIG is currently implemented by trying to connect
to well-known addresses in order to see if IPv4 and/or IPv6
connectivity is available.
In some cases (e.g., walled gardens with no global
connectivity) both probes can fail. If this happens,
query for both IPv4 and IPv6 addresses instead of doing
nothing and failing the query.

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 ensure that __aeabi_f2uiz is embedded in our C library.
This is needed to avoid breaking certain applications when they are
loaded in ICS. It is likely that the issue is due to mis-linked
binaries generated with the stand-alone toolchain (the problem
should not exist if you use ndk-build), but this fix is easier
than asking all app developers to fix their custom build system.

sincos() functions would be turned into infinite calls to
itself if sincos optimization is applied to itself. See
gcc bugzilla http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46926
arm-linux-androideabi-4.4.3 toolchain does not have this problem

When a fatal signal is received, we now write a message to the log
that looks like this:
F/libc ( 1540): Fatal signal 11 (SIGSEGV) at 0xdeadd00d (code=1)
This is useful for debugging fatal signals that turn out not to be
fatal. This also changes the signal reset from SIG_IGN to SIG_DFL,
so that future non-fatal fatal signals are fatal.
The code that blocked SIGUSR1 to avoid being interrupted by the GC
has been removed.
Also, fix minor issues in format_buffer().

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.

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

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.

libc: optimize memmove() with memcpy() if possible.
The get_malloc_leak_info() currently asssumes that the totalMemory out parameter
was pre-initialized to zero before the routine is called. If it is not then the
accumulated totalMemory value will be incorrect. It is likely that many callers
will simply allocate totalMemory on the stack with no initialization and assume
that get_malloc_leak_info will set the proper value.
As an example, the caller in frameworks/base/core/jni/android_os_Debug.cpp
calls get_malloc_leak_info() with the address uninitiazed stack variable
for totalMemory. It is probably best to fix this in get_malloc_leak_info.

can't affect *once_control, but I figured it was better to be safe.
(It seems to have no impact whatsoever on the generated code.)

NOTE: The NDK will need to be modified to enable this feature in
the shared libraries that are generated through it.
When calling sysconf with _SC_NPROCESSORS_ONLN, the value one (1) was
returned on systems with two or more cores, since '/proc/stat' was
incorrectly parsed.
The function line_parser_getc (LineParser* p) read 128 characters of
input for each invocation.
The proper and probably aimed for behavior is to read 128 characters
at the first call, then for each subsequent call only return the next
buffered character until a new read is needed and only then read
another 128 characters.
Due to a flipped comparison between the two variables in_len and
in_pos that track the number of bytes of data read into the input
buffer and how much of it has been parsed, a new group of 128
characters were read at almost every call to line_parser_getc,
overwriting the still unhandled bytes from the previous call to
read. This caused the lines to be read to be sampled more than parsed.

It's subtle but ix is masked with 0x7f000000 so it can never ever have a value

the double's don't use 0x80000000 so this issue didn't exist there.

The problem was that the 'defdname' field of res_state structure
was not properly initialized in __res_vinit(). This field is used
to store the default domain name, which is normally build from
calling gethostname() (see line 549 of res_init.c).
Unfortunately, in the typical Android case, gethostname() returns
an error (the hostname is configured) and a random stack string is
used later to build the DNS search list (see lines 556+ in res_init.c)
For the sake of illustration, let's say the search list is set to
a random value like 'xWLK'.
The end result is that when trying to result an unknown domain name
(e.g. 'www.ptn'), the query fails then the resolver tries to make a
new query with the DNS search list path(s) appended (e.g. 'www.ptn.xWLK').
The patch simply initializes 'defdname' to an empty string to avoid
this when the net.dns.search system property is not set.

Java changes required not to mess up the ordering from bionic will arrive in a
later commit.) In particular, this will give us more correct behavior when on a
6to4 network, in that IPv4 will usually be preferred over 6to4.
Most of RFC 3484 is implemented -- what's not is rule 3 (avoid deprecated
addresses), 4 (prefer home addresses) and 7 (prefer native transport) as they
require low-level access to the kernel routing table via netlink. (glibc also
started out this way, and these rules are primarily useful in pretty obscure
circumstances, so we should be fine for the time being.)
Also, rule 9 (use longest matching prefix) has been modified so it does not try
to sort IPv4 addresses; given current IPv4 addressing practice these rules are
pretty much meaningless. Finally, I've added support for Teredo as a separate
label, with slightly lower preference than 6to4. (Vista puts the preference
below IPv4 by default. glibc puts the preference together with non-tunneled
IPv6.)
Note that this patch removes support for the "sortlist" directive in
resolv.conf; I've never seen it in actual use, it's irrelevant for Android
(since we don't use resolv.conf anyway), and it's not clear how it would be
implemented alongside RFC 3484.
On ARM EABI, 64-bit function parameters must be aligned
to an even/odd register pair. The weird way these stubs
were written (using separate lo/hi parameters) prevented
this alignment from being enforced by the compiler.
This provides a mini-printf implementation that reduces the
size of the dynamic linker by 25 KB, by preventing the drag of
formatting-related routines from the C library.
Also allow traces to be sent to the log, instead of stdout.
NOTE: You now need to modify Android.mk to enable/disable debug
output.

log_channel_t contains fd member, which is file descriptor for
exact logging channel. change cc05d12716
lacks initialization of this member in __write_to_log_init(), thus
logging code is not working, although not crashable.

* commit '5f32207a3db0bea3ca1c7f4b2b563c11b895f276':
Wrap ARM abort() to improve stack trace.
The code generated for Thumb and Thumb2 targets has different handling
for abort(). Because abort() is "noreturn", it doesn't need to preserve
the callee-save registers. The Thumb2 version trashes LR and makes it
impossible to figure out who called abort().
This inserts a trivial stub function; net effect is stack traces are
reasonable after an abort().

GDB will try to read l_ld of linkmaps and compare the value to vma of
.dynamic sections from shared objects. Since linker does not assign l_ld,
GDB will complain about and re-compute l_addr from l_ld. And, GDB will get a
wrong value.
Compiling with -std=c99 defines __STRICT_ANSI__, but the 64 bit types
and type macros should still be defined in this case.
This helps compiling third party code that needs -std=c99 with the NDK.

libc: add void to clock() function prototype
ARMv6 onwards. These architectures provide the load-linked, store-conditional pair of ldrex/strex whose use
is recommended in place of 'swp'. Also, the description of the 'swp' instruction in the ARMv6 reference
manual states that the swap operation does not include any memory barrier guarantees.This fix attempts to
address these issues by providing an atomic swap implementation using ldrex/strex under _ARM_HAVE_LDREX_STREX
macro. This Fix is verified on ST Ericsson's U8500 platform and Submitted on behalf of a third-party:
Surinder-pal SINGH from STMicroelectronics.
Main differences from original code:
1. now log channel for LOG_ID_MAIN may exist even if LOG_ID_RADIO
facility failed.
2. __write_to_log_null() now acts as always successful function.
3. it's more simplier to add new logging channels now
