The DNS copy of reentrant.h was unused, so remove it.
The strtod implementation can use the upstream-netbsd reentrant.h and
get a little closer to what was then upstream. (It's since been replaced

make anything any worse.)

These functions should print assertion violation messages and then
call abort(). They do really not return control flow afterwards.
Consider the declaration of the similar __assert_fail from glibc:
extern void __assert_fail (const char *__assertion,
const char *__file,
unsigned int __line,
const char *__function)
__THROW __attribute__ ((__noreturn__));
Bionic has __noreturn defined in sys/cdefs.h to be that GNU
noreturn attribute.
This patch has a practical value. Consider the following function:
void check(void* ptr) {
assert(ptr != NULL);
}
Without this patch applied, gcc (and presumably clang) shows even in
debug mode:
warning: unused parameter 'ptr' [-Wunused-parameter]
In release mode, NDEBUG is defined and assert() becomes a no-op, as
one should expect. Thus, the warning is shown correctly then.
Another code sample:
float array[2];
int i = 3;
...
assert(i < 2);
array[i] = 0;
gcc says,
warning: array subscript is below array bounds [-Warray-bounds]
In other words, without noreturn attribute, assertions do not
allow a compiler's static analyzer to properly understand
the preconditions.

The situation here is a bit confusing. On 64-bit, rlimit and rlimit64 are
the same, and so getrlimit/getrlimit64, setrlimit/setrlimit64,
and prlimit/prlimit64 are all the same. On 32-bit, rlimit and rlimit64 are
different. 32-bit architectures other than MIPS go one step further by having
an even more limited getrlimit system call, so arm and x86 need to use
ugetrlimit instead of getrlimit. Worse, the 32-bit architectures don't have
64-bit getrlimit- and setrlimit-equivalent system calls, and you have to use
prlimit64 instead. There's no 32-bit prlimit system call, so there's no
easy implementation of that --- what should we do if the result of prlimit64
won't fit in a struct rlimit? Since 32-bit survived without prlimit/prlimit64
for this long, I'm not going to bother implementing prlimit for 32-bit.
We need the rlimit64 functions to be able to build strace 4.8 out of the box.

This is a better solution than the old __warn_references because it's
a compile-time rather than link-time warning, it doesn't rely on something
that doesn't appear to be supported by gold (which is why you only used
to see these warnings on mips builds), and the errors refer to the exact
call site(s) rather than just telling you which object file contains a
reference to the bad function.
This is primarily so we can build bionic for aarch64; building libc.so
caused these warnings to fire (because link time is the wrong time) and
warnings are errors.

<pthread.h> was missing nonnull attributes, noreturn on pthread_exit,

I've also marked the non-standard stuff (where I count glibc rather

If "n" is smaller than the size of "src", then we'll
never read off the end of src. It makes no sense to call
__strncpy_chk2 in those circumstances.
For example, consider the following code:
int main() {
char src[10];
char dst[5];
memcpy(src, "0123456789", sizeof(src));
strncpy(dst, src, sizeof(dst));
dst[4] = '\0';
printf("%s\n", dst);
return 0;
}
In this code, it's clear that the strncpy will never read off
the end of src.

Fortify calls to recv() and recvfrom().
We use __bos0 to match glibc's behavior, and because I haven't
tested using __bos.

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)).

__page_shift and __page_size were accidentally declared in unistd.h with
C linkage - their implementation needs to use the same linkage.
Going forward, though, let's stop the inlining madness and let's kill
the non-standard __getpageshift(). This patch takes getpagesize(3) out
of line and removes __getpageshift but fixes __page_shift and __page_size
for backwards binary compatibility.

Fix source location. Move declaration of __strchr_chk out of
ifdef __BIONIC_FORTIFY which should be available for strchr.cpp
compilation when __BIONIC_FORTIFY is not defined.

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.

Patch is required in NDK headers as well to be able to build multilib

Also make sysconf use PTHREAD_STACK_MIN rather than redefining its
own, different, constant.

glibc doesn't have these, and they prevent ping from building out of
the box because it assumes it can define them.

Linux and *BSD kernels use opposite values to indicate pass/block
in ICMPv6 filters, and assign a different value to the
ICMP6_FILTER sockopt.

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.

Our intptr_t and uintptr_t aren't "long". Add a compilation test so we remember

Allow a new bionic to work with an old init property area by supporting
the old format.
