d0c884d359 Let pthread_create fail if schedparam can't be set
The creation of a thread succeeds even if the requested scheduling
parameters can not be set. This is not POSIX compliant, and even
worse, it leads to a wrong behavior. Let pthread_create() fail in this
case.

7f5aa4f35e bionic: fix integer overflows in chk_malloc(), leak_malloc(), and leak_memalign()
The allocation size in chk_malloc(), leak_malloc(), and leak_memalign()
functions may be rounded up to a small value, leading to buffer overflows.
The code only runs in debugging mode.

This patch complements commit 6f04a0f4 (CVE-2009-0607).

fe6338da91 Adjust memcpy for ARM Cortex A9 cache line size
ARM Cortex A8 use 64 bytes and ARM Cortex A9 use 32 bytes cache line

  Adds code to adjust memcpy cache line size to match A9 cache line
  size.
  Adds a flag to select between 32 bytes and 64 bytes cache line

6baffed252 Add the posix_memalign(3) function to bionic
The posix_memalign(3) function is very similar to the traditional
memalign(3) function, but with better error reporting and a guarantee
that the memory it allocates can be freed.  In bionic, memalign(3)
allocated memory can be freed, so posix_memalign(3) is just a wrapper
around memalign(3).

ee18fb4aac libstdc++: Fix x86 thread-safe one-time-construction implementation.
The root of the problem is that the existing implementation is based on the
ARM C++ ABI, which mandates a different guard variable layout than the
Itanium/x86 C++ one.

This patch modifies the implementation in a way that satisfies both ABIs (and
doesn't require changing the toolchains).

From the release notes:

       africa
               Summer time changes for Morocco (to start late April 2012)

       asia
               Changes for 2012 for Gaza & the West Bank (Hebron) and Syria

       northamerica
               Haiti following US/Canada rules for 2012 (and we're assuming,
               for now anyway, for the future).

Also include a change made internally to the 'generate' script as part of
the tzdata2011m update that apparently never made it to AOSP; the original
checkin comment for which was:

    Update to tzdata2011m.

    Fixes for Europe/Tiraspol (Moldova) and all four Ukrainian zones.

    Also show the MD5 of the downloaded data, for comparison against the MD5
    given in the announcement mails. (There's a plan to move to proper signing,
    but that's not implemented on their end yet.)

(I'm repeating the tzdata change for the convenience of anyone grepping the
log, since the 2012 tzdata releases also contain the 2011m changes; 2011m
is the only missing release I noticed.)

cb08204053 libc/x86: ensure the stack 16-byte aligned when tasks created
Currently Renderscript sample code RsBalls crashed on x86 when SSE2
enabled. The root cause is that the stack was not 16-byte aligned
from the beginning when the processes/threads were created, so the
RsBalls crashed when SSE2 instructions tried to access the variables
on the stack.

- For the thread created by fork():
Its stack alignment is determined by crtbegin_{dynamic, static}.S

- For the thread created by pthread_create():
Its stack alignment is determined by clone.S. __thread_entry( ) is
a standard C function. In order to have its stack be aligned with
16 byte properly, __thread_entry() needs the stack with following
layout when it is called:
layout #1 (correct)
--------------
|            |
-------------- <--ESP (ECX - 20)
| ret EIP    |
-------------- <--ECX - 16
| arg0       |
-------------- <--ECX - 12
| arg1       |
-------------- <--ECX - 8
| arg2       |
-------------- <--ECX - 4
| unused     |
-------------- <--ECX (16-byte boundary)

But it has following layout for now:
layout #2: (incorrect)
--------------
|            |
-------------- <--ESP (ECX - 16)
| unused     |
-------------- <--ECX - 12
| arg0       |
-------------- <--ECX - 8
| arg1       |
-------------- <--ECX - 4
| arg2       |
-------------- <--ECX (16-byte boundary)

Fixed in this patch.

I/DEBUG   (  113):     #07  eip: 0011fb94  /system/lib/libdvm.so

Root cause:
The atfork uses the mutex handler_mutex to protect the atfork_head. The
parent will call __bionic_atfork_run_prepare() to lock the handler_mutex,
and need both the parent and child to unlock their own copy of handler_mutex
after fork. At that time, the owner of hanlder_mutex is set as the parent.
If we apply the kernel_id fix, then the child's kernel_id will be set as
child's tid.
The handler_mutex is a recursive lock, and pthread_mutex_unlock(&hander_mutex)
will fail because the mutex owner is the parent, while the current tid
(__get_thread()->kernel_id) is child, not matched with the mutex owner.
At that time, the handler_mutex is left in lock state.If the child wants to
fork other process after than, then it will try to lock handler_mutex, and
then be deadlocked.

Fix:
Since the child has its own copy of vm space from the the parent, the
child space's handler_mutex should be reset to the initialized state.

d8bc6e7119 bionic: Fix wrong kernel_id in pthread descriptor after fork()
After forking, the kernel_id field in the phtread_internal_t returned by pthread_self()
is incorrect --- it's the tid from the parent, not the new tid of the
child.

The root cause is that: currently the kernel_id is set by
_init_thread(), which is called in 2 cases:
(1) called by __libc_init_common(). That happens when the execv( ) is
called after fork( ). But when the zygote tries to fork the android
application, the child application doesn't call execv( ), instread, it
tries to call the Java main method directly.
(2) called by pthread_create(). That happens when a new thread is
created.

For the lead thread which is the thread created by fork(), it should
call execv() but it doesn't, as described in (1) above. So its kernel_id
will inherit the parent's kernel_id.

Fixed it in this patch.
