aa754dca90 Improve stack overflow diagnostics.
We notify debuggerd of problems by installing signal handlers. That's
fine except for when the signal is caused by us running off the end of
a thread's stack and into the guard page.

any more.

da4a3e6515 EABI syscall cleanup.
We cleaned up the auto-generated ones a while back to not touch
the stack unnecessarily if they have <= 4 arguments. This patch
cleans up some hand-crafted ones.

Also improve comments in clone.S.

b95cf0d23a Fix pthread_getattr_np, pthread_attr_setguardsize, and pthread_attr_setstacksize.
pthread_getattr_np was reporting the values supplied to us, not the values we
actually used, which is kinda the whole point of pthread_getattr_np.

pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL
for any size that wasn't a multiple of the system page size. This is
unnecessary. We can just round like POSIX suggests and glibc already does.

Also improve the error reporting for pthread_create failures.

ce4783ce76 Upgrade to tzcode2013d.
Well, kinda... localtime.c still contains a bunch of Android-specific
hacks, as does strftime.c. But the other files are now exactly the same
as upstream.

This catches up with several years of bug fixes, and fixes most of the
compiler warnings that were in this code. (Just two remain.)

From the release notes:

  Changes affecting future time stamps:

    Morocco's midsummer transitions this year are July 7 and August 10,
    not July 9 and August 8.  (Thanks to Andrew Paprocki.)

    Israel now falls back on the last Sunday of October.
    (Thanks to Ephraim Silverberg.)

  Changes affecting past time stamps:

    Specify Jerusalem's location more precisely; this changes the pre-1880
    times by 2 s.

  Changing affecting metadata only:

    Fix typos in the entries for country codes BQ and SX.

f936ef1a9f Include linux/termios.h from sys/ioctl.h.
On NetBSD and glibc, including sys/ioctl.h provides some
terminal ioctl data structures such as struct winsize. For
compatibility, provide these via sys/ioctl.h in bionic as well.
bionic does not have its own definitions for these structures, so
get them from the Linux kernel definitions.

2753e12af5 libc/arch-arm/bionic/memcpy.a9.S: memcpy from cortex-strings.
This memcpy code uses NEON/VFP to achieve very good performance
on ARMv7-A processors. It is specifically tuned for A15 but should
provide good performance on A9 also. It is equivalent to the code
in cortex-strings rev 116.

This patch is a follow up the existing gerrit change:

I7f6f77995f3ca903ad9c66d14261441667a2a935

This version includes a tweak for performance on misaligned
buffers and splits the header comment into license and
documentation sections.

64a4f6adf7 Update x86 machine/endian.h from upstream
After download new version from upstream (OpenBSD 1.17) did the
following:
 * changed all u_int* types to uint*
 * add #include <sys/types.h>

All these changes are Android-specific and had been done before for
previous version (1.14).

1d36ee1a6e bionic: prevent root processes from calling __system_property_add
If a root process other than init calls __system_property_add, which
it should never do, it will break the design assumption that there is
only one mutator.

Pass O_EXCL to open() in map_prop_region_rw to ensure that only one
process ever has the property pages open for write.

1540f601be bionic: revert to a single (larger) property area
d329697 is too complicated.  Change the multiple property pages back to
a single 128K property area that's mapped in entirely at initialization
(the memory will not get allocated until the pages are touched).

d329697 has other changes useful for testing (moving property area
initialization inside bionic and adding __system_property_set_filename)
so undo the change manually rather than with git revert.

996cdc4b1a bionic: reimplement property area as hybrid trie/binary tree
See the comments for an explanation of how properties are stored.

The trie structure is designed to scale better than the previous
array-based implementation.  Searching an array with n properties
required average O(n) string compares of the entire key; searching the
trie requires average O(log n) string compares of each token (substrings
between '.' characters).

cb215a7e9e bionic: make property area expandable
The property area is initially one 4K region, automatically expanding as
needed up to 64 regions.

To avoid duplicating code, __system_property_area_init() now allocates
and initializes the first region (previously it was allocated in init's
init_property_area() and initialized in bionic).  For testing purposes,
__system_property_set_filename() may be used to override the file used
to map in regions.

16d1af167f libc: add limited FORTIFY_SOURCE support for clang
In 829c089f83, we disabled all
FORTIFY_SOURCE support when compiling under clang. At the time,
we didn't have proper test cases, and couldn't easily create targeted
clang tests.

This change re-enables FORTIFY_SOURCE support under clang for a
limited set of functions, where we have explicit unittests available.
The functions are:

* memcpy
* memmove
* strcpy
* strncpy
* strcat
* strncat
* memset
* strlen (with modifications)
* strchr (with modifications)
* strrchr (with modifications)

It may be possible, in the future, to enable other functions. However,
I need to write unittests first.

For strlen, strchr, and strrchr, clang unconditionally calls the
fortified version of the relevant function. If it doesn't know the
size of the buffer it's dealing with, it passes in ((size_t) -1),
which is the largest possible size_t.

I added two new clang specific unittest files, primarily copied
from fortify?_test.cpp.

I've also rebuild the entire system with these changes, and didn't
observe any obvious problems.

5cf32de7a0 bionic: move system property writing from init to bionic
Move the implementation of writing to the system property area
from init to bionic, next to the reader implementation.  This
will allow full property testing to be added to bionic tests.

Add new accessor and waiting functions to hide the implementation
from watchprops and various bionic users.

Also hide some of the implementation details of the property area
from init by moving them into _system_properties.h, and other details
from everybody by moving them into system_properties.h.

0f020d18b1 Handles spurious wake-ups in pthread_join()
Removed 'join_count' from pthread_internal_t and switched to using the flag
PTHREAD_ATTR_FLAG_JOINED to indicate if a thread is being joined. Combined with
a switch to a while loop in pthread_join, this fixes spurious wake-ups but
prevents a thread from being joined multiple times. This is fine for
two reasons:

1) The pthread_join specification allows for undefined behavior when multiple
   threads try to join a single thread.

2) There is no thread safe way to allow multiple threads to join a single
   thread with the pthread interface.  The second thread calling pthread_join
   could be pre-empted until the thread is destroyed and its handle reused for
   a different thread.  Therefore multi-join is always an error.

61e699a133 Clean up abort.
* A dlmalloc usage error shouldn't call abort(3) because we want to
  cause a SIGSEGV by writing the address dlmalloc didn't like to an
  address the kernel won't like, so that debuggerd will dump the
  memory around the address that upset dlmalloc.

* Switch to the simpler FreeBSD/NetBSD style of registering stdio
  cleanup. Hopefully this will let us simplify more of the stdio
  implementation.

* Clear the stdio cleanup handler before we abort because of a dlmalloc
  corruption error. This fixes the reported bug, where we'd hang inside
  dlmalloc because the stdio cleanup reentered dlmalloc.

885f3b9cad Implement malloc_usable_size for debug impls.
- Implemented chk_memalign.
- Fixed a few bugs in leak_memalign.
- Implemented {leak,fill,check,qemu}_malloc_usable_size.
- Make malloc_usable_size update at run time.
- Add malloc_test.cpp as a small set of tests for the
  malloc debug routines.
- Fix the qemu routines since it's been broken since it moved to C++.
- Add support for the %u format to the out_vformat in libc_logging.cpp.
  This is used by the emulator code.

Tested using the bionic-unit-tests with setprop libc.debug.malloc
set to 1, 5, and 10.

I tested as much as possible on the emulator, but tracing doesn't appear
to be working properly.

cf870199d5 FORTIFY_SOURCE: strcat / strncat optimize
__strcat_chk and __strncat_chk are slightly inefficient,
because they end up traversing over the same memory region
two times.

This change optimizes __strcat_chk / __strncat_chk so they
only access the memory once. Although I haven't benchmarked these
changes, it should improve the performance of these functions.

__strlen_chk - expose this function, even if -D_FORTIFY_SOURCE
isn't defined. This is needed to compile libc itself without
-D_FORTIFY_SOURCE.

Add support for fortify source level 2 to strncpy.
This will enable detection of more areas where strncpy
is used inappropriately. For example, this would have detected
bug 8727221.

Move the fortify_source tests out of string_test.cpp, and
put it into fortify1_test.cpp.

Create a new fortify2_test.cpp file, which copies all
the tests in fortify1_test.cpp, and adds fortify_source level
2 specific tests.

e66ad7809e [NETFILTER]: Fix iptables ABI breakage
Pick up Linux kernel patch 2748e5dec7ca8a3804852c7c4171f9156384d15c
from 2007

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2748e5dec7ca8a3804852c7c4171f9156384d15c

[NETFILTER]: Fix iptables ABI breakage on (at least) CRIS
With the introduction of x_tables we accidentally broke compatibility
by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of
XT_TABLE_MAXNAMELEN, which is two bytes larger.

On most architectures it doesn't really matter since we don't have
any tables with names that long in the kernel and the structure
layout didn't change because of alignment requirements of following
members. On CRIS however (and other architectures that don't align
data) this changed the structure layout and thus broke compatibility
with old iptables binaries.

Changing it back will break compatibility with binaries compiled
against recent kernels again, but since the breakage has only been
there for three releases this seems like the better choice.

From the release notes:

  Changes affecting current and future time stamps:

    Palestine observed DST starting March 29, 2013.  (Thanks to
    Steffen Thorsen.)  From 2013 on, Gaza and Hebron both observe DST,
    with the predicted rules being the last Thursday in March at 24:00
    to the first Friday on or after September 21 at 01:00.

    Assume that the recent change to Paraguay's DST rules is permanent,
    by moving the end of DST to the 4th Sunday in March every year.
    (Thanks to Carlos Raúl Perasso.)

  Changes affecting past time stamps:

    Fix some historical data for Palestine to agree with that of
    timeanddate.com, as follows:

          The spring 2008 change in Gaza and Hebron was on 00:00 Mar 28, not
          00:00 Apr 1.

          The fall 2009 change in Gaza and Hebron on Sep 4 was at 01:00, not
          02:00.

          The spring 2010 change in Hebron was 00:00 Mar 26, not 00:01 Mar 27.

          The spring 2011 change in Gaza was 00:01 Apr 1, not 12:01 Apr 2.

          The spring 2011 change in Hebron on Apr 1 was at 00:01, not 12:01.

          The fall 2011 change in Hebron on Sep 30 was at 00:00, not 03:00.

    Fix times of habitation for Macquarie to agree with the Tasmania
    Parks & Wildlife Service history, which indicates that permanent
    habitation was 1899-1919 and 1948 on.

  Changing affecting metadata only:

    Macquarie Island is politically part of Australia, not Antarctica.
    (Thanks to Tobias Conradi.)

    Sort Macquarie more-consistently with other parts of Australia.
    (Thanks to Tim Parenti.)

185ce72d00 Update to latest cortexa15 memcpy code.
This uses the new code original submitted as memcpy.a15.S as
the base. However, the old code handled unaligned src/dst better
so that was spliced in. I optimized the original unaligned code by
removing a few unnecessary instructions. I optimized the a15 code by
rewriting the pre and post code. I also modified the main loop to add
a pld so that larger copies would not stall waiting for memory.

Test cases for the new memcpy:

- Copy all sized values from 0 to 1024 bytes, using whatever alignment
  is returned by malloc.
For each alignment case described below, the test copied from 0 to 128
bytes.
- Src and dst pointers are both aligned to the same value, starting
  at one going through every power of two up to and including 128.
- Src aligned to double word boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to double word boundary.
- Src aligned to 16 bit boundary, dst aligned to word boundary.
- Src aligned to word boundary, dst aligned to 16 byte boundary.
- Src aligned to word boundary, dst aligned to 1 byte from a word
  boundary.
- Src aligned to word boundary, dst aligned to 2 bytes from a word
  boundary.
- Src aligned to word boundary, dst aligned to 3 bytes from a word
  boundary.
- Src aligned to 1 byte from a word boundary, dst aligned to a word
  boundary.
- Src aligned to 2 bytes from a word boundary, dst aligned to a word
  boundary.
- Src aligned to 3 bytes from a word boundary, dst aligned to a word
  boundary.

Cases to verify the unaligned source code properly aligns to a 16 bit
boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
  4 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
  8 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
  12 + 128 bit boundary.
- Src aligned to 1 byte from a 128 bit boundary, dst aligned to
  16 + 128 bit boundary.

In all cases, a two byte fencepost was placed at the end of the
destination to verify that only the requested number of bytes were copied.

7b4d77e400 Make abort messages available to debuggerd.
This adds __libc_fatal, cleans up the internal logging code a bit more,
and switches suitable callers over to __libc_fatal. In addition to logging,
__libc_fatal stashes the message somewhere that the debuggerd signal handler
can find it before calling abort.

In the debuggerd signal handler, we pass this address to debuggerd so that
it can come back with ptrace to read the message and present it to the user.

378b0e1ea2 Update getaddrinfo to RFC6724
Currently, our getaddrinfo implementation does not conform to
any IETF standard. It follows draft-ietf-6man-rfc3484-revise-01,
but that draft has expired. Update the policy table to RFC6724.

(cherry-pick of e919b116d35aa7deb24ddece69c491e24c3b0d6f.)

96449b3dc1 Extra logging in pthread_create.
pthread_create returns EAGAIN when it can't allocate a pthread_internal_t,
when it can't allocate a stack for the new thread, or when clone(2) fails
because there are too many threads. It's useful to be able to know why your
pthread_create just failed, so add some logging.
