From the release notes:
Changes affecting near-future time stamps
Turkey begins DST on 2014-03-31, not 03-30. (Thanks to Faruk Pasin
for the heads-up, and to Tim Parenti for simplifying the update.)
Changes affecting past time stamps
Fiji ended DST on 2014-01-19 at 02:00, not the previously-scheduled
03:00. (Thanks to Steffen Thorsen.)
Ukraine switched from Moscow to Eastern European time on 1990-07-01
(not 1992-01-01), and observed DST during the entire next winter.
(Thanks to Vladimir in Moscow via Alois Treindl.)
In 1988 Israel observed DST from 04-10 to 09-04, not 04-09 to
09-03. (Thanks to Avigdor Finkelstein.)

This is a much simpler implementation that lets the kernel
do as much as possible.

The kernel uses the very misleading name "si_tid", but glibc uses the more
intention-revealing "si_timerid". We should let people use that.
(Added because I wanted to improve SI_TIMER siginfo_t dumping in strace.)

This adds ARMv8 optimized string handling functions to Bionic.
The implementations live in a generic/ directory because there will
likely be more CPU specific versions (e.g. Cortex-A53 vs. Cortex-A57)
later.
These implementations are 50%+ faster on current v8 models.

Many compilers may optimize away the overflow check `msg + l < msg',
where `msg' is a pointer and `l' is an integer, because pointer
overflow is undefined behavior in C.
Use a safe precondition test `l >= eom - msg' instead.

Functions protected with !defined(__LP64__) will be get build as C++
symbols for X64 build. This is not the desired work. So protect the
implementation with !defined(__LP64__) as well.

GCC is removing these checks anyway because it knows the arguments
must be non-null, so leaving this code around is just confusing.
We know from experience that people were shipping code with locking
bugs because they weren't checking for error returns. Failing hard
like glibc does seems the better choice. (And it's what the checked
in code was already doing; this patch doesn't change that. It just
makes it more obvious that that's what's going on.)

This replaces the non-standard pthread_mutex_lock_timeout_np, which we have
to keep around on LP32 for binary compatibility.

This is part of the upstream sync (Net/Open/Free BSDs expose the
nameser.h in their public headers).

We only support CLOCK_REALTIME and CLOCK_MONOTONIC for now,
so we us a single bit from pthread_cond_t->value to denote
the clock type. Note that this reduces the width of the counter
to 30 bits, but this should be large enough for all practical
purposes.

The only way the setitimer call can fail is if the unsigned number of seconds is
too large to fit in the kernel's signed number of seconds. If you schedule a
68-year alarm, glibc will fail by returning 0 and BSD will fail by returning -1.

* TARGET_USES_LOGD is true or false, yes is not valid
* was supposed to be in the libc_bionic definition
Change-Id: I7f15d0fe61205641f7310ba9762df885e6c959d0
Note that a dynamically-linked binary will still probably see two attempts ---
one by the dynamic linker (which will set its copy of the flag so it won't try
again) and then one by the executable itself (which gets a new uninitialized
copy of the flag).

This costs us about 1000 fewer syscalls, which makes "adb shell strace date"
a lot more readable (which is the reason I've been meaning to fix this for a
long time now), but also actually saves a measurable amount of time.
Longer-term we should try to keep the tzdata mmap(2)ed in like libcore
does.

Also add the corresponding constant, struct, and function declarations
to <sys/socket.h>, and perfunctory tests so we know that the symbols
actually exist.

* libc (fatal) logging now makes socket connection to the
user-space logging service.
* Add a TARGET_USES_LOGD make flag for BoardConfig.mk to manage
whether logd is enabled for use or not.

When libc.debug.malloc is enabled, stack backtraces fail with:
bionic/libc/bionic/libc_logging.cpp:378: assertion "conversion
specifier unsupported" failed
The cause was a change to the format specifier from "%08x" to
"%0*x" to pass the field width as an additional parameter.
Unfortunately this modifier isn't supported by out_vformat() in
libc_logging.cpp.
Changed to use "%016x" if __LP64__ is defined; "%08x" otherwise.

From the release notes:
Changes affecting near-future time stamps:
Jordan switches back to standard time at 00:00 on December 20, 2013.
The 2006-2011 transition schedule is planned to resume in 2014.
(Thanks to Steffen Thorsen.)
Changes affecting past time stamps:
In 2004, Cuba began DST on March 28, not April 4.

A warning about signed vs unsigned comparison was converted
into an error here :
...
struct stat st;
if (st.st_size > sizeof(prop_area) {
...
st_size is either an off64_t, which is a signed type. It's
worth investigating why this didn't trigger a warning on 32 bit,
where it's signed as well.

This change constitutes the minimum amount of
work required to move the code over to C++, address
compiler warnings, and to make it const correct and
idiomatic (within the constraints of being called
from C code).

Also undo some of the mess where we have OpenBSD <stdio.h> but a mix of
different BSD's implementations.
In this first pass, I've only moved easy OpenBSD stuff.

Why do we see so many bogus strict-aliasing warnings? Because we asked GCC to
cause trouble on arm and mips.
Change-Id: I25d7fd036b6afff7ccfa799abe0dc1579ead2847
I screwed up when I originally imported these files; they're in lib/libc/
in the upstream tree; there is no top-level libc/ (though there is a top-level
common/, so those files stay where they are).
Change-Id: I7c5e2224a4441ab0e33616a855a8c6aacfeac46f
Our <machine/asm.h> files were modified from upstream, to the extent
that no architecture was actually using the upstream ENTRY or END macros,
assuming that architecture even had such a macro upstream. This patch moves
everyone to the same macros, with just a few tweaks remaining in the
<machine/asm.h> files, which no one should now use directly.
I've removed most of the unused cruft from the <machine/asm.h> files, though
there's still rather a lot in the mips/mips64 ones.
Bug: 12229603
Change-Id: I2fff287dc571ac1087abe9070362fb9420d85d6d
I broke the mips build yesterday because it doesn't use
<private/bionic_asm.h> like the other architectures, including mips64.
I want to move mips closer to mips64 to try to avoid this kind of thing
in future.
Change-Id: Idb985587ff355b9e5e765c1f5671dc0144cd2488
This gives us:
* <dirent.h>
struct dirent64
readdir64, readdir64_r, alphasort64, scandir64
* <fcntl.h>
creat64, openat64, open64.
* <sys/stat.h>
struct stat64
fstat64, fstatat64, lstat64, stat64.
* <sys/statvfs.h>
struct statvfs64
statvfs64, fstatvfs64.
* <sys/vfs.h>
struct statfs64
statfs64, fstatfs64.
This also removes some of the incorrect #define hacks we've had in the
past (for stat64, for example, which we promised to clean up way back
in bug 8472078).

bionic/libc/arch-arm64/syscalls/read.S ends with:
b.hi __set_errno
ret
END(read)
If __set_errno returns int, it will set w0 to 0xFFFFFFFF, which means
x0 is 0x00000000FFFFFFFF. When interpreted as a ssize_t that is
INT_MAX, not -1.
Change __set_errno to return long, which will cause x0 to be set instead
of w0.
