e1dd3c287b bionic: import heaptracker as chk_malloc
This patch is a rewrite of libc.debug.malloc = 10 (chk_malloc).  It provides
the same features as the original (poison freed memory, detect heap overruns
and underruns), except that it provides more debugging information whenever it
detects a problem.

In addition to the original features, the new chk_malloc() implementation
detects multiple frees within a given range of the last N allocations, N being
configurable via the system property libc.debug.malloc.backlog.

Finally, this patch keeps track of all outstanding memory allocations.  On
program exit, we walk that list and report each outstanding allocation.

(There is support (not enabled) for a scanner thread periodically walks over
the list of outstanding allocations as well as the backlog of recently-freed
allocations, checking for heap-usage errors.)

Feature overview:

  1) memory leaks
  2) multiple frees
  3) use after free
  4) overrun

Implementation:

-- for each allocation, there is a:
  1) stack trace at the time the allocation is made
  2) if the memory is freed, there is also a stack trace at the point
  3) a front and rear guard (fence)
  4) the stack traces are kept together with the allocation

-- the following lists and maintained

  1) all outstanding memory allocations
  3) a backlog of allocations what are freed; when you call free(), instead of
     actually freed, the allocation is moved to this backlog;
  4) when the backlog of allocations gets full, the oldest entry gets evicted
     from it; at that point, the allocation is checked for overruns or
     use-after-free errors, and then actually freed.
  5) when the program exits, the list of outstanding allocations and the
     backlog are inspected for errors, then freed;

To use this, set the following system properties before running the process or
processes you want to inspect:

libc.malloc.debug.backlog # defaults to 100
libc.malloc.debug 10

When a problem is detected, you will see the following on logcat for a multiple
free:

9d40326830 arm: rewrite crtbegin* as C files.
Rewrite
 crtbegin.S     -> crtbegin.c
 crtbegin_so.S  -> crtbegin_so.c

This change allows us to generate PIC code without relying
on text relocations.

As a consequence of this rewrite, also rewrite
  __dso_handle.S    -> __dso_handle.c
  __dso_handle_so.S -> __dso_handle_so.c
  atexit.S          -> atexit.c

In crtbegin.c _start, place the __PREINIT_ARRAY__, __INIT_ARRAY__,
__FINI_ARRAY__, and __CTOR_LIST__ variables onto the stack, instead of
passing a pointer to the text section of the binary.

This change appears sorta wonky, as I attempted to preserve,
as much as possible, the structure of the original assembly.
As a result, you have C files including other C files, and other
programming uglyness.

Result: This change reduces the number of files with text-relocations
from 315 to 19 on my Android build.

Before:
  $ scanelf -aR $OUT/system | grep TEXTREL | wc -l
  315

After:
  $ scanelf -aR $OUT/system | grep TEXTREL | wc -l
  19

7d2e24eb16 bionic: introduce libc.debug.malloc.program
libc.debug.malloc.program  provides an additional level of control over which
processes to enable libc.debug.malloc functionality for.  The string value of
libc.debug.malloc.program is matched against the program name; if the value of
libc.debug.malloc.program is a substring of the program name, then malloc debug
is applied to that program at whatever level libc.debug.malloc specifies.

If lib.debug.malloc.program is not specified, then libc.debug.malloc has the
same effect as before.

For example, to enable libc.deubug.malloc = 10 only to the mediaserver, do the
following:

   adb root # necessary for setprop
   adb setprop libc.debug.malloc.program mediaserver
   adb setprop libc.debug.malloc 10
   adb kill -9 $(pid mediaserver)

08e72d0161 bionic: add support for non-NEON memcpy() on NEON SoCs
Some SoCs that support NEON nevertheless perform better with a non-NEON than a
NEON memcpy().  This patch adds build variable ARCH_ARM_USE_NON_NEON_MEMCPY,
which can be set in BoardConfig.mk.  When ARCH_ARM_USE_NON_NEON_MEMCPY is
defined, we compile in the non-NEON optimized memcpy() even if the SoC supports
NEON.

2fd81ef71c bionic: allow the board to customize MALLOC_ALIGNMENT
Currently the dlmalloc allocates the memory with 8-byte alignment.
According to the com.aurorasoftworks.quadrant.ui.professional benchmark data:
We can get much better memory performance if we change it to be 16-byte aligned.
For example, On Nexus-S:
8-byte aligned :
    1378 1070  1142 1665 1765  1163 1179  1263  1404 avg: 1336.555555556
16-byte aligned:
    1691 1731  1780 1691 1671  1678 1802  1758  1780 avg: 1731.333333333
                                                    gain: 29.53%

That patch provides flexibity to customize the MALLOC_ALIGNMENT from the
board config.The macro MALLOC_ALIGNMENT defaults to 8.
To change it, please define BOARD_MALLOC_ALIGNMENT in the BoardConfig.mk:
BOARD_MALLOC_ALIGNMENT := <whatever>

0753dc653e pthread: Invalidate stale stack pointers on pthread_exit()
A call to pthread_key_delete() after pthread_exit() have unmapped the stack of a thread
but before the ongoing pthread_join() have finished executing will result in an access
to unmapped memory.
Avoid this by invalidating the stack_base and tls pointers during pthread_exit().

This is based on the investigation and proprosed solution by
Srinavasa Nagaraju <srinavasa.x.nagaraju@sonyericsson.com>

worse, it leads to a wrong behavior. Let pthread_create() fail in this

If two or more rapid dns requests for the same server are done
from different threads it turns into separate dns reques, if
the response of the request isn't found in the cache.

This patch avoid multiple request for the same server by
letting subsequents request wait until the first request

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).

b091dd9bf2 libc: continue to use Android's custom linker script
By default, Android no longer compiles code using it's custom
linker script /build/core/armelf.xsc. However, this causes
problems for libc. Certain programs linked using older versions
of GOLD expect libc.so to export __exidx_start and __exidx_end.
Removing the custom linker script causes libc.so not to export
those symbols.

For now, continue using the old linker script, until we can
figure out a better solution.

1a78fbb5c8 Initialize TLS before any application code is run.
Since e19d702b8e, dlsym and friends use recursive mutexes that
require the current thread id, which is not available before the libc
constructor. This prevents us from using dlsym() in .preinit_array.

This change moves TLS initialization from libc constructor to the earliest
possible point - immediately after linker itself is relocated. As a result,
pthread_internal_t for the initial thread is available from the start.

As a bonus, values stored in TLS in .preinit_array are not lost when libc is
initialized.

cd15bacf33 Fix segv when unwinding stack past __libc_init.
This change fixes a segmentation fault in the libc unwinder when it goes
past __libc_init.

Unwind instructions for __libc_init direct it to grab the return address from
the stack frame. Without this change, the unwinder gets a wild address and
looks up further unwind instructions for the routine at that address. If it's
unlucky enough to hit an existing function, it will try to unwind it. Bad
things happen then.

With this change, the return address always points to the _start function,
which does not have unwind instructions associated with it. This stop the
unwind process.

__libc_init never returns, so this does not affect program execution, other
than adding 4 bytes on the main thread stack.

8f78ddb422 Update to tzdata2012c.
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.)

faca92f2f1 Handle pthread-related changes (mutex/atfork)
First commit:

Revert "Revert "am be741d47: am 2f460fbe: am 73b5cad9: Merge "bionic: Fix wrong kernel_id in pthread descriptor after fork()"""

This reverts commit 06823da2f0.

Second commit:

bionic: fix atfork hanlder_mutex deadlock

This cherry-picks commit 34e89c232d

After applying the kernel_id fix, the system refused to boot up and we
got following crash log:
I/DEBUG   (  113): pid: 618, tid: 618  >>> org.simalliance.openmobileapi.service:remote <<<

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.

126601dd3f Fixed to #include correct 32-bit headers; Refreshed libc/kernel headers
This patch fixes an issue where 64-bit hreaders are incorrectly included
in kernel headers.  For example, file "libc/kernel/arch-x86/asm/io.h"
incorreclty includes "io_64.h" (missing, BTW) instead of "io_32.h".

The reason is because CONFIG_X86_32 isn't considered pre-defined in
"kernel_default_arch_macros" for x86, and clean_header.py doesn't
look at it at all anyway (ie. __i386__ is also ignored, but it's
okay since x86 cross compiler defines it back)

Fixed 2 tools/*py, README.TXT, and refreshed libc/kernel headers

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.

d1860ad8dd fnmatch.c: Update to version in OpenBSD HEAD
Upgrade fnmatch.c from OpenBSD version 1.13 to 1.16.
This is needed primarily to address CVE-2011-0419.

This is a straight copy from upstream's version at
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/fnmatch.c and
incorporates the following changes:

Revision 1.16:
New fnmatch(3) implementation which is not recursive.
Written and provided under BSD licence by William A. Rowe Jr.
Originally released in Apache APR-1.4.5.
Merged class matching code from r1.14 and PATH_MAX check from r1.15.
ok miod millert

Revision 1.15:
Put a limit on recursion during matching, and reject input of size greater
or equal PATH_MAX. Based on similar fix made in NetBSD.
ok miod@ millert@

Revision 1.14:
POSIX character class support for fnmatch(3) and glob(3).  OK deraadt@

Version 1.14 introduced charclasses.h, which we copy unmodified
from upstream version 1.1.
http://www.openbsd.org/cgi-bin/cvsweb/src/lib/libc/gen/charclass.h

  Many functions have no effects except the return value and their

  Such a function can be subject to common subexpression elimination
  and loop optimization just as an arithmetic operator would be.

string.h: Mark many commently used string functions as "pure", to

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.

06e1831f19 Prevent potential stall on dns proxy operations.
Update wire protocol to return and process error code first.
This will make sure dns proxy operations do not stall when
an internal error happens.
Also fix a compiler warning.
Also fix a potential buffer overflow.
And use correct types (uint32_t) rather than int when reading from network.

Nick Kralevich
9ec0f03a0d Add relro support
Add support for PT_GNU_RELRO. This allows the static linker to
indicate that certain regions of memory should be marked as
"read-only" after dynamic linking is complete.

See:
  * http://www.akkadia.org/drepper/nonselsec.pdf (section 6)
  * http://tk-blog.blogspot.com/2009/02/relro-not-so-well-known-memory.html

Note that this change has no effect on Android right now, because
we don't compile our code with relro enabled.

5fbf2e0992 libc: Define new symbol visibility macros
This patch defines a few new macros that can be used to control the
visibility of symbols exported by the C library:

- ENTRY_PRIVATE() can be used in assembly sources to indicate
  that an assembler function should have "hidden" visibility, i.e.
  will never be exported by the C library's shared library.

  This is the equivalent of using __LIBC_HIDDEN__ for a C function,
  but ENTRY_PRIVATE() works like ENTRY(), and must be used with
  END() to tag the end of the function.

- __LIBC_ABI_PUBLIC__ can be used to tag a C functions as being
  part of the C library's public ABI. This is important for a
  few functions that must be exposed by the NDK to maintain
  binary compatibility.

  Once a symbol has been tagged with this macro, it shall
  *never* be removed from the library, even if it becomes
  directly unused due to implementation changes
  (e.g. __is_threaded).

- __LIBC_ABI_PRIVATE__ can be used for C functions that should
  always be exported by the C library because they are used by
  other libraries in the platform, but should not be exposed
  by the NDK. It is possible to remove such symbols from the
  implementation if all callers are also modified.

+ Add missing END() assembly macro for x86

- removed libc/arch-sh, linker/arch-sh, libc/kernel/arch-sh

- simplified libc/SYSCALLS.TXT

738b175a93 Make sure __u64 is defined even for strict ansi or -std=c99
The x86 asm headers define __u64 regardless of __STRICT_ANSI__.
The linux/videodev2.h header requires __u64 to be defined, thus
this fixes compiling with -std=c99 when including the
linux/videodev2.h header.

In glibc, the asm/types.h header defines __u64 regardless of
__STRICT_ANSI__.

This is the change for the generated arch-arm/asm/types.h
header, as produced by the update_all.py script (without all
the other unrelated changes that the script produces).

FWIW, the same issue also is present in
arch-sh/asm/types.h, but there are no source headers for
arch-sh in external/kernel-headers (and regenerating the
headers simply removes that file).

David 'Digit' Turner
b57db7581c libc: Fix recursive mutex lock implementation.
This fixes a bug that was introduced in the latest pthread optimization.
It happens when a recursive lock is contented by several threads. The main
issue was that the atomic counter increment in _recursive_increment() could
be annihilated by a non-conditional write in pthread_mutex_lock() used to
update the value's lower bits to indicate contention.

This patch re-introduces the use of the global recursive lock in
_recursive_increment(). This will hit performance, but a future patch
will be provided to remove it from the source code.

e8e1efeafb Update to tzdata2011n.
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).

ea29cd5a4a Eliminate duplicate copies of constants.
sys/personality.h and linux/personality.h contain mostly
identical contents. Eliminate dups.

d6045cba4e Don't generate sys/linux-unistd.h
linux-unistd.h was here for reference purposes, but shouldn't
have been accessible to client code. Delete it.
