72645164b6 Add arch-x86_64/include/machine.
This is basically the other half of I5de76f6c46ac87779f207d568a86bb453e2414de
from Pavel Chupin <pavel.v.chupin@intel.com>, but taking the exact upstream
_types.h instead of the modified version. (I was confused when I suggested
otherwise.)

I've also cleaned up the internal_types.h situation; we weren't gaining
anything from these empty files, and there is no upstream internal_types.h
for x86_64.

e4ffd9f234 Regenerate the system call stubs (to get x86_64).
This touches the x86 stubs too because arm, x86, and x86_64 now
all share the same header (at a source level), which causes a
reordering of the #include lines.

d3e64a3f40 Add x86_64 to the bionic headers.
Manual changes:

  cpp.py: cope with macros that refer to other macros.

  defaults.py: x86 no longer always implies __i386__; use __i386__ to replace
  the kernel CONFIG_X86_32 flag.

  asm/page.h: the upstream page.h isn't a uapi header and no longer includes
  the stuff we were using it for. Let's just have our own static file, since
  it's the same for all our architectures (both 32- and 64-bit).

  sys/select.h: we used to use the various FD_SET-related macros from the
  kernel header files, but they've gone. Adjust by adding trivial equivalent
  definitions.

Automated changes:

  libc/kernel/arch-x86, libc/kernel/common: regenerated from
  external/kernel-headers.

afcc0cccda Add mmap64()
This adds mmap64() to bionic so that it is possible to have
large offset passed to kernel. However, the syscall mechanism
only passes 32-bit number to kernel. So effectively, the
largest offset that can be passed is about 43 bits (since
offset is signed, and the number passed to kernel is number
of pages (page size == 4K => 12 bits)).

bd8e6749b7 cdefs.h: introduce __bos0
Introduce __bos0 as a #define for __builtin_object_size((s), 0).
This macro is intended to be used for places where the standard
__bos macro isn't appropriate.

memcpy, memmove, and memset deliberately use __bos0. This is done
for two reasons:

1) I haven't yet tested to see if __bos is safe to use.
2) glibc uses __bos0 for these methods.

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.

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.

ad59322ae4 Pull the pthread_key_t functions out of pthread.c.
This was originally motivated by noticing that we were setting the
wrong bits for the well-known tls entries. That was a harmless bug
because none of the well-known tls entries has a destructor, but
it's best not to leave land mines lying around.

Also add some missing POSIX constants, a new test, and fix
pthread_key_create's return value when we hit the limit.

a0ee07829a Upgrade libm.
This brings us up to date with FreeBSD HEAD, fixes various bugs, unifies
the set of functions we support on ARM, MIPS, and x86, fixes "long double",
adds ISO C99 support, and adds basic unit tests.

It turns out that our "long double" functions have always been broken
for non-normal numbers. This patch fixes that by not using the upstream
implementations and just forwarding to the regular "double" implementation
instead (since "long double" on Android is just "double" anyway, which is
what BSD doesn't support).

All the tests pass on ARM, MIPS, and x86, plus glibc on x86-64.

32417fb376 libc: use more secure system properties if available
Currently, system properties are passed via the environment
variable ANDROID_PROPERTY_WORKSPACE and a file descriptor passed
from parent to child. This is insecure for setuid executables,
as the environment variable can be changed by the caller.

Modify system property handling so that we get the properties
from a root owned properties file, rather than using an
environment variable.  Fall back to the environment variable
if the file doesn't exist.

2c5153b043 libc: add getauxval()
Add support for getauxval().  This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.

This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.

a4b2dc016f Add signalfd call to bionic
Add signalfd() call to bionic.

Adding the signalfd call was done in 3 steps:
- add signalfd4 system call (function name and syscall
  number) to libc/SYSCALLS.TXT
- generate all necessary headers by calling
  libc/tools/gensyscalls.py. This patch is adding
  the generated files since the build system
  does not call gensyscalls.py.
- create the signalfd wrapper in signalfd.cpp and add
  the function prototype to sys/signalfd.h

(cherry-pick of 0c11611c11, modified to
work with older versions of GCC still in use on some branches.)

4fa35d8ae8 Fix <endian.h> and <sys/endian.h>.
Previously we'd been relying on getting the machine-specific <endian.h>
instead of the top-level <endian.h>, and <sys/endian.h> was basically broken.
Now, with this patch and the previous patch we should have <endian.h>
and <sys/endian.h> behaving the same. This is basically how NetBSD's endian.h
works, and was probably how ours was originally intended to work.

86ec05acc9 Update the kernel headers to match external/kernel-headers.
Note that the Linux kernel handed over responsibility for most of the
socket constants to glibc some time ago. Someone had updated our
external/kernel-headers file but not regenerated the bionic headers,
so this change copies the missing stuff from the old bionic <linux/socket.h>
into <sys/socket.h>. This is what glibc does.

I've hacked a few of the other files to #include <sys/socket.h> for
backward compatibility, but even so this requires numerous other
changes to switch people over from direct inclusion of <linux/...> headers.
