ARM: make CRT_LEGACY_WORKAROUND work as intended
To properly support legacy ARM shared libraries, libc.so needs
to export the symbols __dso_handle and atexit, even though
these are now supplied by the crt startup code.
This patch reshuffles the existing CRT_LEGACY_WORKAROUND
conditionally compiled code slightly so it works as the
original author likely intended.

FORTIFY_SOURCE: strlen check.
This test is designed to detect code such as:

memcpy(buf, "1234567890", sizeof(buf));
size_t len = strlen(buf); // segfault here with _FORTIFY_SOURCE
printf("%d\n", len);
return 0;
}
or anytime strlen reads beyond an object boundary. This should
help address memory leakage vulnerabilities and make other
unrelated vulnerabilities harder to exploit.

libc: implement some FORTIFY_SOURCE functions
Add initial support for -D_FORTIFY_SOURCE to bionic for the
following functions:
* memcpy
* memmove
* strcpy
* strcat
* strncpy
* strncat
This change adds a new version of the above functions which passes
the size of the destination buffer to __builtin___*_chk.
If the compiler can determine, at compile time, that the destination
buffer is large enough, or the destination buffer can point to an object
of unknown size, then the check call is bypassed.
If the compiler can't make a compile time decision, then it calls
the __*_chk() function, which does a runtime buffer size check
These options are only enabled if the code is compiled with
-D_FORTIFY_SOURCE=1 or 2, and only when optimizations are enabled.
Please see
* http://gcc.gnu.org/onlinedocs/gcc/Object-Size-Checking.html
* http://gcc.gnu.org/ml/gcc-patches/2004-09/msg02055.html
for additional details on FORTIFY_SOURCE.
Testing: Compiled the entire Android tree with -D_FORTIFY_SOURCE=1,
and verified that everything appears to be working properly.
Also created a test buffer overflow, and verified that it was
caught by this change.

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:

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

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.

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>

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.

This patch uses the new hardware feature macros for x86 to define
various compile-time macros used to make the C library use

Note that previously, we relied on the macros being defined by
build/core/combo/TARGET_linux-x86.mk, but this is no longer the
case.

libc: provide atomic operations will full barriers for NDK apps.
__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.

Added _memmove_words
Added a memmove() variant for Dalvik's System.arraycopy()
implementation. It guarantees 16-bit or 32-bit atomicity depending
on the alignment of the arguments.

libc: Add ftruncate64 and improve 64-bit parameter syscall handling.
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>

Allow dlclose() to properly call static C++ destructors.
With this patch _and_ an upcoming build/ patch, the destruction
of static C++ objects contained in shared libraries will happen
properly when dlclose() is called.
Note that this change introduces crtbegin_so.S and crtend_so.S which
are currently ignored by the build system.
+ move definition of __dso_handle to the right place
(before that, all shared libraries used the __dso_handle
global variable from the C library).
Note that we keep a 'weak' __dso_handle in aeabi.c to avoid
breaking the build until the next patch to build/core/combo/
appears. We will be able to remove that later.
+ move bionic/aeabi.c to arch-arm/bionic/ (its proper location)
NOTE: The NDK will need to be modified to enable this feature in
the shared libraries that are generated through it.

GDB looks for specific opcode sequences when trying to recognize a stack

patch does the same here, so that the trampolines can be correctly identified.

Fix TLS access for ARMv6 and beyond.
For performance reasons, we don't call the kernel helper. Instead, we directly
access the TLS register on ARMv6 and higher. For ARMv5TE, keep using the hard-coded
address populated by the kernel on each task switch.
NOTE: Since we don't call the kernel helper, this must precisely match your
kernel configuration. This is controlled by setting the ARCH_ARM_HAVE_TLS_REGISTER
variable to 'true' in your board configuration file.
