3975cec694 Remove (near-)duplicate definitions of size_t and ssize_t.
The near duplicates upset fussier compilers that insist that
typedefs be exactly the same, but the fix isn't to make all
copies identical...

c30396f5f2 libc: Fix alphasort() signature (and implementation).
The declaration for alphasort() in <dirent.h> used the deprecated:

  int alphasort(const void*, const void*);

while both Posix and GLibc use instead:

  int alphasort(const struct dirent** a, const struct dirent** b);

See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html

This patch does the following:

- Update the declaration to match Posix/GLibc
- Get rid of the upstream BSD code which isn't compatible with the new
  signature.
- Implement a new trivial alphasort() with the right signature, and
  ensure that it uses strcoll() instead of strcmp().
- Remove Bionic-specific #ifdef .. #else .. #endif block in
  dirent_test.cpp which uses alphasort().

Even through strcoll() currently uses strcmp(), this does the right
thing in the case where we decide to update strcoll() to properly
implement locale-specific ordered comparison.

c124baaf29 libc: Provide ucontext_t/mcontext_t/<sys/ucontext.h>
This patch updates the C library headers to provide ucontext_t
definitions for three architectures.

+ Fix <signal.h> to always define 'struct sigcontext'.

The new declarations are announced with new macros defined in
<sys/cdefs.h> in order to make it easier to adapt client code
that already defines its own, incompatible, versions of the
structures seen here.

f8a2c51bf3 LONG_LONG_MIN/MAX: Move declarations to <limits.h>
LONG_LONG_MIN, LONG_LONG_MAX and ULONG_LONG_MAX are
GLibc-specific macros that are better defined in <limits.h>
instead of the current exotic location (<pthread.h>).

Note that GCC's <limits.h> only defines these macros
when __GNU_LIBRARY__ is also defined. This is only the
case when building against GLibc, so manually redefine
the macros here.

Note that using LLONG_MIN/LLONG_MAX/ULLONG_MAX is the
C99-compliant way to get these values, but it's easier
to define these compatibility macros for the sake of
porting existing code.

4e75c4b2d7 Fix perf_event_open syscall for x86 and mips
perf_event_open syscall has a different syscall number for
the 3 supported architectures: arm, x86 and mips. Currenlty
only the arm syscall number is defined for all architectures.
Tracing tools like perf will not work on other architectures
than arm.

Add the different values for perf_event_open on x86 and mips
and run gensyscalls.py to update generated headers.

7d56ccbfaa Always take GCC's definition of NULL.
There's a (bad) definition of NULL in <linux/stddef.h>, and this
definition of NULL, and the One True definition in the <stddef.h> provided
by the compiler. This change at least kills one of the bad duplicates.
Killing the <linux/stddef.h> one is harder, because it's in a generated
file.

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.

829c089f83 disable _FORTIFY_SOURCE under clang
Clang and _FORTIFY_SOURCE are just plain incompatible with
each other.  First of all, clang doesn't understand the
__attribute__((gnu_inline)) header. Second of all,
Clang doesn't have support for __builtin_va_arg_pack()
and __builtin_va_arg_pack_len() (see
http://clang.llvm.org/docs/UsersManual.html#c_unimpl_gcc)

Until we can resolve these issues, don't even try using
_FORTIFY_SOURCE under clang.

260bf8cfe0 FORTIFY_SOURCE: strlen check.
This test is designed to detect code such as:

int main() {
  char buf[10];
  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.

f3913b5b68 FORTIFY_SOURCE: enhanced memcpy protections.
Two changes:

1) Detect memory read overruns.

For example:

int main() {
  char buf[10];
  memcpy(buf, "abcde", sizeof(buf));
  sprintf("%s\n", buf);
}

because "abcde" is only 6 bytes, copying 10 bytes from it is a bug.
This particular bug will be detected at compile time.  Other similar
bugs may be detected at runtime.

2) Detect overlapping buffers on memcpy()

It is a bug to call memcpy() on buffers which overlap. For
example, the following code is buggy:

  char buf3[0x800];
  char *first_half  = &buf3[0x400];
  char *second_half = &buf3[1];
  memset(buf3, 0, sizeof(buf3));
  memcpy(first_half, second_half, 0x400);
  printf("1: %s\n", buf3);

We now detect this at compile and run time.

a3e230d1fa FORTIFY_SOURCE: Add openat, fix bug
Add fortify_source support for openat(). This change requires that
an argument be supplied when using O_CREAT.

Fix unnecessary call to __open_2. If, at compile time, we know that
"flags" is constant and DOESN'T contain O_CREAT, the call to __open_2
is useless.

realloc should NOT be marked with __attribute__((malloc)). Quoting:

For reference, __mallocfunc is defined in sys/cdefs.h as:

0a2301598c 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.

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).

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

not use or rely on them.

So copy them to private <bionic_time.h> and <resolv_iface.h> headers
and use a guard macro to avoid conflicts when both headers are included
at the same time.

The idea is that we're going to fix the other platform modules to
include these private headers. After this is done, we will remove the
duplicate definitions from <resolv.h> and <time.h>

85aad90956 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).

0fec6b9d88 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.

9831ad3ce6 libc: speed-up flockfile()/funlockfile()
For Honeycomb, we added proper file thread-safety for
all FILE* operations. However, we did implement that by
using an out-of-band hash table to map FILE* pointers
to phtread_mutex_t mutexes, because we couldn't change
the size of 'struct _sFILE' without breaking the ABI.

It turns out that our BSD-derived code already has
some support code to extend FILE* objects, so use it
instead. See libc/stdio/fileext.h

This patch gets rid of the hash table, and put the
mutex directly into the sFILE extension.

to automatically call the underlying functions when the process is
threaded to obtain the necessary locking.  A private mutex is added
to protect __sglue, the internal list of FILE handles, and another
to protect the one-time initialization.  Some routines in libc that
use getc() change to use getc_unlocked() as they're either protected
by their own lock or aren't thread-safe routines anyway.

                  struct ethtool_drvinfo in <linux/ethtool.h>)

All scripts will use the content of external/kernel-headers/original by default now.

The generated code removes all empty lines and trailing whitespace. This is useful
to ensure a unified output even if we change the parser again in the future.

The top-level disclaimer has been edited with update instructions to regenerate
the headers when needed.

Also, a warning is now inserted every 8th line in the final output:

/* WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS */

Changes under kernel/arch-arm and kernel/arch-x86 should correspond to whitespace
differences and additionnal struct definitions that were missed by the previous
parser implementation.

5c8c00a95a libc: Fix the definition of SIGRTMAX
After this change, SIGRTMAX will be set to 64 (instead of 32 currently).
Note that this doesn't change the fact that our sigset_t is still defined
as a 32-bit unsigned integer, so most functions that deal with this type
won't support real-time signals though.

Add missing declarations:
  INET_ADDRSTRLEN

  IN6_IS_ADDR_MC_GLOBAL

It has been reported that these prevent compilation of the Boost libraries
with the NDK. The corresponding patch has already been performed under
development/ndk/platforms/android-3/include.

95d751feac 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>

because gcc would not allow calling a static function from an asm
statement.  Instead, using GCC visibility is work around.

3cf53d1a78 Fixes for the ARM-specific bswap_16, bswap_32, and bswap_64.
1. Make the feature test work by excluding known-deficient processors, so
we don't have to maintain a complete list of all the processors that support
REV and REV16.

2. Don't abuse 'register' to get an effect similar to GCC's +l constraint,
but which was unnecessarily restrictive.

3. Fix __swap64md so _x isn't clobbered, breaking 64-bit swaps.

4. Make <byteswap.h> (which declars bswap_16 and friends) use <endian.h>
rather than <sys/endian.h>, so we get the machine-dependent implementations.

bionic/libc/include/../include/stdlib.h:138:23: warning: parameter '__fd' set but not used [-Wunused-but-set-parameter]

By adding __attribute((unused)) to __fd, the warning is gone, and this
attribute is compatible with gcc-4.4.0, gcc-4.3.1 gcc-4.2.1.
There is no any side effect.

78c1c04ced pthread: introduce pthread_setname_np() as a mean to give names to threads
... so that each cloned process at the kernel level can be named
independently. Tools like 'top' can display the CPU/memory statistics
for each process's thread if "Show Threads" mode is on.

With this function in place, we can convert dalvik/Thread.c setThreadName()
function over this function. This feature ought to be provided by the
underlying C library and not coded directly in Dalvik.

e4fa46e75c Set SA_RESTORER in sigaction()
GDB looks for specific opcode sequences when trying to recognize a stack
frame as a signal trampoline.  The sequences it looks for happen to be those
created when SA_RESTORER is set, since glibc always sets a restorer.  This
patch does the same here, so that the trampolines can be correctly identified.
