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.

cd587701c8 FORTIFY_SOURCE: add umask check
Verify that the call to umask makes sense. While this wouldn't
have detected bug 7094213 (because the low order bits were all zero),
it might detect other similar bugs.

This makes the constants correspond to those in the Linux kernel's
include/linux/syslog.h, but keeping our old badly-named constants for
source compatibility.

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.

1ad10a566e Add getsid system call to bionic
Add getsid() system call to bionic for
all architectures. This is needed for various tools
(e.g. perf).

Adding the getsid system call was done in 3 steps:
() add getsid 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.
() add the system call signature to libc/include/unistd.h

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.
