libc: implement kernel vdso syscalls for i386
This patch uses __kernel_vsyscall instead of "int 0x80"
as the syscall entry point. AT_SYSINFO points to
an adapter to mask the arch specific difference and gives a
performance boost on i386 architecture.

forkpty: set the output fd to -1 on the slave side.

Don't call clock_getres in sysconf.
There are a hundred other reasons why we can't run on kernels old enough
to not have all the clocks covered by sysconf.
This was causing trouble for jemalloc 4.1.0 in a seccomp-constrained process
because jemalloc 4.1.0 introduced a call to sysconf that caused us to make
clock_getres syscalls for the first time, leading to SIGSYS.

The main reason for doing this is not performance but to allow
the linker use raise() which was not working because pthread_kill()
couldn't find pthread_self() thread because the global thread
list is initialized in libc.so and the linker's version of this
list is empty.

Malloc debug rewrite.
The major components of the rewrite:
- Completely remove the qemu shared library code. Nobody was using it
and it appears to have broken at some point.
- Adds the ability to enable/disable different options independently.
- Adds a new option that can enable the backtrace on alloc/free when
a process gets a specific signal.
- Adds a new way to enable malloc debug. If a special property is
set, and the process has an environment variable set, then debug
malloc will be enabled. This allows something that might be
a derivative of app_process to be started with an environment variable
being enabled.
- get_malloc_leak_info() used to return one element for each pointer that
had the exact same backtrace. The new version returns information for
every one of the pointers with same backtrace. It turns out ddms already
automatically coalesces these, so the old method simply hid the fact
that there where multiple pointers with the same amount of backtrace.
- Moved all of the malloc debug specific code into the library.
Nothing related to the malloc debug data structures remains in libc.
- Removed the calls to the debug malloc cleanup routine. Instead, I
added an atexit call with the debug malloc cleanup routine. This gets
around most problems related to the timing of doing the cleanup.
The new properties and environment variables:
libc.debug.malloc.options
Set by option name (such as "backtrace"). Setting this to a bad value
will cause a usage statement to be printed to the log.
libc.debug.malloc.program
Same as before. If this is set, then only the program named will
be launched with malloc debug enabled. This is not a complete match,
but if any part of the property is in the program name, malloc debug is
enabled.
libc.debug.malloc.env_enabled
If set, then malloc debug is only enabled if the running process has the
environment variable LIBC_DEBUG_MALLOC_ENABLE set.

Implement if_nameindex(3)/if_freenameindex(3).
This is just a subset of the recently-implemented getifaddrs(3), though if
we want to handle interfaces (such as "rmnet_*") that don't have an address,
we need to either expose ifaddrs_storage and keep track of which interfaces
we've already seen (which is pretty messy), or refactor the netlink code so
we can reuse it and just extract the information we need for if_nameindex(3).
This patch goes the latter route.
Also clean up if_nametoindex(3) and if_indextoname(3).

system_properties.cpp: special case ro.* properties
Currently, reads of ro.* properties are treated differently than
writes of ro.* properties. When writing an ro.* property, we ignore
the "ro." portion of the property, and base the security decision
on the label of the remaining portion.
See https://android.googlesource.com/platform/system/core/+/e7a9e52740c952c623f7842ffa1d09b58b45e552/init/property_service.cpp
line 120-126
For example, for writing, the label associated with
"ro.build.fingerprint" comes from the /property_contexts file
entry:
# ro.build.fingerprint is either set in /system/build.prop, or is
# set at runtime by system_server.
build.fingerprint u:object_r:fingerprint_prop:s0
However, we fail to follow this same special case when sorting
properties into files. Instead, ro.build.fingerprint is assigned
u:object_r:default_prop:s0 instead of u:object_r:fingerprint_prop:s0
Ignore the "ro." portion when sorting properties into files.
This will make reads and writes of properties use the same label.

Revert "Revert "Implement getifaddrs(3)/freeifaddrs(3).""
This reverts commit 76814a8250fd5e1502909ef5e10e4d166cc96c0e.
This differs from the original in fixing the GCC -Werror build:
bionic/libc/bionic/ifaddrs.cpp: In function 'void __handle_netlink_response(ifaddrs**, nlmsghdr*)':
bionic/libc/bionic/ifaddrs.cpp:113:62: error: use of old-style cast [-Werror=old-style-cast]
ifinfomsg* ifi = reinterpret_cast<ifinfomsg*>(NLMSG_DATA(hdr));
This appears to be a GCC bug; the GCC command-line correctly uses -isystem,
and manually adding #pragma GCC system_header doesn't help. So just turn the
warning off for GCC for now. We won't need to worry about building with GCC
soon anyway.

sem_timedwait with a null timeout doesn't mean "forever".
It actually means "crash immediately". Well, it's an error. And callers are
much more likely to realize their mistake if we crash immediately rather
than return EINVAL. Historically, glibc has crashed and bionic -- before
the recent changes -- returned EINVAL, so this is a behavior change.

Reset access to system properties on reinitialization
Treat subsequent calls to __system_properties_init() as a
reinitialization of system properties and revoke access to prop files
that have been previously mapped but that the process's current context
does not have access to. Additionally reset the no_access_ flag in
case permissions have loosened and previously unaccessible files can now
be accessed.
This is meant to work around an issue that setcon() does not revoke
mmap() mappings, so we must manually revoke them after a successful
setcon() call.

Do not set properties in bionic_systrace
Currently, if the debug.atrace.tags.enableflags property is not found,
it is set to a safe value such that a pointer to this property can be
stored for later access. This may result in selinux denials because not
all processes write permissions for this property or permission to
connect to the property write socket at all.
Change I6d953c0c281fd72ad3eba8a479fd258023579b5b writes this property to
a safe value upon boot, which greatly decreases the cases in which this
property will not be accessible and removes the need to write it here.
This commit removes this write.

Revert "Revert "Remove __sinit and __sdidinit.""
This reverts commit c8bae05f3ff9f1c736f7be70fa17d02795d748bb.
We were breaking init (ueventd) because we initialize system properties
before we initialize stdio. The new system property implementation uses
stdio to read from /property_contexts, so we end up touching stdio data
structures before they've been initialized.
This second attempt takes things further by removing the stdio initialization
function altogether. The data structures for stdin/stdout/stderr can be
statically initialized as data, and -- since we already had to give the
atexit implementation a backdoor for stdio -- we can just admit that we
need to clean up stdio, and that we always do so last.
This patch also removes the 17 statically pre-allocated file structures,
so the first fopen will now allocate a block of 10 (the usual overflow
behavior). I did this just to make my life simpler, but it's not actually
necessary to remove it if we want it back.

Separate properties by selabel
The purpose of this change is to add read access control to the property
space.
In the current design, a process either has access to the single
/dev/__properties__ file and therefore all properties that it contains
or it has access to no properties. This change separates properties
into multiple property files based on their selabel, which allows
creation of sepolicies that allow read access of only specific sets of
properties to specific domains.

Don't use __thread in __cxa_thread_finalize().
Currently we use __thread variable to store thread_local_dtors,
which makes tsan test fork_atexit.cc hang. The problem is as below:
The main thread creates a worker thread, the worker thread calls
pthread_exit() -> __cxa_thread_finalize() -> __emutls_get_address()
-> pthread_once(emutls_init) -> emutls_init().
Then the main thread calls fork(), the child process cals
exit() -> __cxa_thread_finalize() -> __emutls_get_address()
-> pthread_once(emutls_init).
So the child process is waiting for pthread_once(emutls_init)
to finish which will never occur.
It might be the test's fault because POSIX standard says if a
multi-threaded process calls fork(), the new process may only
execute async-signal-safe operations until exec functions are
called. And exit() is not async-signal-safe. But we can make
bionic more reliable by not using __thread in
__cxa_thread_finalize().

Change _stdio_handles_locking into _caller_handles_locking.
It is reported by tsan that funlockfile() can unlock an unlocked mutex.
It happens when printf() is called before fopen() or other stdio stuff.
As FLOCKFILE(fp) is called before __sinit(), _stdio_handles_locking is false,
and _FLOCK(fp) will not be locked. But then cantwrite(fp) in __vfprintf()
calls__sinit(), which makes _stdio_handles_locking become true, and
FUNLOCKFILE(fp) unlocks _FLOCK(fp).
Change _stdio_handles_locking into _caller_handles_locking,
so __sinit() won't change its value. Add test due to my previous fault.

mmap: fix calculation of is_private_anonymous variable
Currently is_private_anonymous is calculated as true if _either_
MAP_PRIVATE or MAP_ANONYMOUS is set, which is a mistake.
According to Documentation/vm/ksm.txt, "KSM only merges anonymous
(private) pages, never pagecache (file) pages". MAP_PRIVATE can
still be set on file cache pages so in order to not redundantly
set MADV_MERGEABLE on pages that are not fitted for it, both
MAP_PRIVATE and MAP_ANONYMOUS should be set.
Along with this fix, add an extra check that the mapped page is
not a stack page before setting MADV_MERGEABLE for it. Stack pages
change too quickly and always end up in KSM 'page_volatile' list.

Fix tsan abort for lake of __libc_auxv initialization.
If tsan is used, the following callchain can happen:
__libc_preinit() -> __libc_init_globals() ->
__libc_init_vdso() -> strcmp() -> __tsan_init()
-> sysconf(_SC_PAGE_SIZE) -> getauxval().
But __libc_auxv is initialized in __libc_init_common(),
after __libc_init_globals(). One simple way to fix
this is to initialize __libc_auxv at __libc_init_globals().

extend the PTRDIFF_MAX size check to mremap
This removes another way to obtain objects larger than PTRDIFF_MAX. The
only known remaining hole is now jemalloc's merging of virtual memory
spans.
Technically this could be wrapped in an __LP64__ ifndef since it can't
occur on 64-bit due to the 1:1 split. It doesn't really matter either
way.

libc_init_common.cpp: Clarify when environment stripping occurs
The current comment implies that we only strip sensitive
environment variables on executing a setuid program. This is
true but incomplete. The AT_SECURE flag is set whenever a
security transition occurs, such as executing a setuid program,
SELinux security transition, executing a file with file capabilities,
etc...

the [stack] indicator may no longer be correct.

make mmap fail on requests larger than PTRDIFF_MAX
Allocations larger than PTRDIFF_MAX can be successfully created on
32-bit with a 3:1 split, or in 32-bit processes running on 64-bit.
Allowing these allocations to succeed is dangerous, as it introduces
overflows for `end - start` and isn't compatible with APIs (mis)using
ssize_t to report either the size or an error. POSIX is guilty of this,
as are many other Android APIs. LLVM even considers the `ptr + size`
case to be undefined, as all pointer arithmetic compiles down to signed
operations and overflow is treated as undefined for standard C pointer
arithmetic (GNU C `void *` arithmetic works differently).
This also prevents dlmalloc from allocating > PTRDIFF_MAX as it doesn't
merge mappings like jemalloc. A similar check will need to be added in
jemalloc's code path for huge allocations.
The musl libc implementation also performs this sanity check.

Only close stdin/stdout/stderr for debug malloc.
The debug malloc code unconditionally closes stdin/stdout/stderr,
which means that other atexit functions cannot use them. Only
close these if there is a debug malloc final function to call.
This doesn't appear to be a problem on most normal applications or the
atexit_exit bionic unit test would be failing. However, if you
enable stat dumping in jemalloc, nothing prints. Most likely trying
to add an atexit function from within libc is causing that atexit
to run after the debug malloc atexit function.

Move PAGE_MASK into <sys/user.h>.
I'm removing the TODO on the assumption that being compatible with glibc
is more useful than BSD. The new internal "bionic_page.h" header factors
out some duplication between libc and the linker.

add fortified implementations of fread/fwrite
A __size_mul_overflow utility is used to take advantage of the checked
overflow intrinsics in Clang and GCC (>= 5). The fallback for older
compilers is the optimized but less than ideal overflow checking pattern
used in OpenBSD.

make vdso function pointers read-only at runtime
Global, writable function pointers are low-hanging fruit for hijacking
control flow with an overflow from a global buffer or an arbitrary write
vulnerability. This moves the function pointer table into a dedicated
page and makes it read-only at runtime, similar to RELRO.
This increases the memory usage of the library by just under one page.
This could be avoided by having the linker load the vdso by replacing
weak symbols. It's not significant within the Zygote spawning model
though because it's read-only after early init.

Allow NULL in pthread_mutex_lock/unlock.
The pthread_mutex_lock and pthread_mutex_unlock were allowed to
fail silently on L 32 bit devices when passed a NULL. We changed
this to a crash on 32 bit devices, but there are still games that make
these calls and are not likely to be updated. Therefore, once again
allow NULL to be passed in on 32 bit devices.

libc: Add O_PATH support for fgetxattr / fsetxattr
Support O_PATH file descriptors when handling fgetxattr and fsetxattr.
This avoids requiring file read access to pull extended attributes.
This is needed to support O_PATH file descriptors when calling
SELinux's fgetfilecon() call. In particular, this allows the querying
and setting of SELinux file context by using something like the following
code:
int dirfd = open("/path/to/dir", O_DIRECTORY);
int fd = openat(dirfd, "file", O_PATH | O_NOFOLLOW);
char *context;
fgetfilecon(fd, &context);

Simplify close(2) EINTR handling.
This doesn't affect code like Chrome that correctly ignores EINTR on
close, makes code that tries TEMP_FAILURE_RETRY work (where before it might
have closed a different fd and appeared to succeed, or had a bogus EBADF),
and makes "goto fail" code work (instead of mistakenly assuming that EINTR
means that the close failed).
Who loses? Anyone actively trying to detect that they caught a signal while
in close(2). I don't think those people exist, and I think they have better
alternatives available.

Change on handling of SIGEV_THREAD timers.
1. Don't prevent calling callback when SIGEV_THREAD timers are disarmed by timer_settime.
As in POSIX standard: The effect of disarming or resetting a timer with pending
expiration notifications is unspecified. And glibc didn't prevent in this situation, so I
think it is fine to remove the support.
2. Still prevent calling callback when SIGEV_THREAD timers are deleted by timer_delete.
As in POSIX standard: The disposition of pending signals for the deleted timer is unspecified.
However, glibc handles this (although that is not perfect). And some of our tests in
time_test.cpp depend on this feature as described in b/18039727. so I retain the support.
3. Fix some flaky test in time_test.cpp, and make "time*" test pass on bionic-unit-tests-glibcxx.

Provide writer preference option in rwlock.
Previous implementation of rwlock contains four atomic variables, which
is hard to maintain and change. So I make following changes in this CL:
1. Add pending flags in rwlock.state, so we don't need to synchronize
between different atomic variables. Using compare_and_swap operations
on rwlock.state is enough for all state change.
2. Add pending_lock to protect readers/writers waiting and wake up
operations. As waiting/wakeup is not performance critical, using a
lock is easier to maintain.
3. Add writer preference option.
4. Add unit tests for rwlock.

Add O_APPEND flag for __libc_write_stderr.
For DeathTests, we are testing the output of stderr to check if it is the
death we are expecting. To collect the output, Gtest redirects stderr to
a temporary file. But in __libc_write_stderr in libc_logging.cpp, we are
writing to stderr without a O_APPEND flag, so a new message will overwrite
a previous message.
The above situation makes almost all the DeathTests fail on host. Because
the expected message are always overwritten in host DeathTests. So I add
O_APPEND flag in __libc_write_stderr, which makes all host DeathTests pass.

Let g_thread_list_lock only protect g_thread_list.
As glibc/netbsd don't protect access to thread struct members by a global
lock, we don't want to do it either. This change reduces the
responsibility of g_thread_list_lock to only protect g_thread_list.

set errno to ENOENT in getauxval per glibc 2.19
Bionic's getauxval(...) implementation returns zero when entries are
missing. Zero can be a valid value, so there is no unambiguous way of
detecting an error. Since glibc 2.19, errno is set to ENOENT when an
entry is missing to make it possible to detect this. Bionic should match
this behavior as code in the Linux ecosystem will start relying on it to
check for the presence of newly added entries.

Make pthread join_state not protected by g_thread_list_lock.
1. Move the representation of thread join_state from pthread.attr.flag
to pthread.join_state. This clarifies thread state change.
2. Use atomic operations for pthread.join_state. So we don't need to
protect it by g_thread_list_lock. g_thread_list_lock will be reduced
to only protect g_thread_list or even removed in further changes.

Fix "faccessat ignores flags"
The kernel system call faccessat() does not have any flags arguments,
so passing flags to the kernel is currently ignored.
Fix the kernel system call so that no flags argument is passed in.
Ensure that we don't support AT_SYMLINK_NOFOLLOW. This non-POSIX
(http://pubs.opengroup.org/onlinepubs/9699919799/functions/access.html)
flag is a glibc extension, and has non-intuitive, error prone behavior.
For example, consider the following code:
symlink("foo.is.dangling", "foo");
if (faccessat(AT_FDCWD, "foo", R_OK, AT_SYMLINK_NOFOLLOW) == 0) {
int fd = openat(AT_FDCWD, "foo", O_RDONLY | O_NOFOLLOW);
}
The faccessat() call in glibc will return true, but an attempt to
open the dangling symlink will end up failing. GLIBC documents this
as returning the access mode of the symlink itself, which will
always return true for any symlink on Linux.
Some further discussions of this are at:
* http://lists.landley.net/pipermail/toybox-landley.net/2014-September/003617.html
* http://permalink.gmane.org/gmane.linux.lib.musl.general/6952
AT_SYMLINK_NOFOLLOW seems broken by design. I suspect this is why this
function was never added to POSIX. (note that "access" is pretty much
broken by design too, since it introduces a race condition between
check and action). We shouldn't support this until it's clearly
documented by POSIX or we can have it produce intuitive results.
Don't support AT_EACCESS for now. Implementing it is complicated, and
pretty much useless on Android, since we don't have setuid binaries.
See http://git.musl-libc.org/cgit/musl/commit/?id=0a05eace163cee9b08571d2ff9d90f5e82d9c228
for how an implementation might look.

Make .note.android.ident section type SH_NOTE
The .note.android.ident section is only used by GDB, which doesn't
care what section type the section is, but it would be convenient
for readelf -n to be able to find the section too.
The old way of getting the .note.android.ident section to be of type
SH_NOTE involved compiling from .c to .s using gcc, running sed to
change progbits to note, and then compiling from .s to .o using gcc.
Since crtbrand.c only contains a section containing data, a
crtbrand.S can be checked in that will compile on all platforms,
avoiding the need for sed.
Also add crtbrand.o to crtbegin_so.o so that libraries also get
the note, and to the crt workaround in arm libc.so.

Remove no-op sed step when compiling crtbrand.o
crtbrand.c was compiled to a .s file, run through a sed script
to translate a %progbits to %note, and the compiled to .o.
However, when the sed command was copied from the original source
it was not updated to use the new name of the section (.note.ABI-tag
to .note.android.ident), so it didn't modify the file. Since the
section has been generated with type %progbits instead of %note for
two years, just delete the whole sed step.

for LP64 these will be hidden. for LP32 we were cowards and left
them all public for compatibility (though i don't think we ever
dremeled to see whether it was needed). we don't have an easy
way to recognize additions, though, so we can't prevent adding
new turds.
Add a mechanism to prevent the adding of new turds, and use that
mechanism on the fchmod/fchmodat system calls.

Add fchmodat(AT_SYMLINK_NOFOLLOW) and fchmod O_PATH support
Many libc functions have an option to not follow symbolic
links. This is useful to avoid security sensitive code
from inadvertantly following attacker supplied symlinks
and taking inappropriate action on files it shouldn't.
For example, open() has O_NOFOLLOW, chown() has
lchown(), stat() has lstat(), etc.
There is no such equivalent function for chmod(), such as lchmod().
To address this, POSIX introduced fchmodat(AT_SYMLINK_NOFOLLOW),
which is intended to provide a way to perform a chmod operation
which doesn't follow symlinks.
Currently, the Linux kernel doesn't implement AT_SYMLINK_NOFOLLOW.
In GLIBC, attempting to use the AT_SYMLINK_NOFOLLOW flag causes
fchmodat to return ENOTSUP. Details are in "man fchmodat".
Bionic currently differs from GLIBC in that AT_SYMLINK_NOFOLLOW
is silently ignored and treated as if the flag wasn't present.
This patch provides a userspace implementation of
AT_SYMLINK_NOFOLLOW for bionic. Using open(O_PATH | O_NOFOLLOW),
we can provide a way to atomically change the permissions on
files without worrying about race conditions.
As part of this change, we add support for fchmod on O_PATH
file descriptors, because it's relatively straight forward
and could be useful in the future.
The basic idea behind this implementation comes from
https://sourceware.org/bugzilla/show_bug.cgi?id=14578 , specifically
comment #10.

Split the shared group data from the shared passwd data.
Found by the toybox id(1) which calls both getpwuid(3) and getgrgid(3) before
looking at either result. The use of a shared buffer in this code meant that
even on a single thread, the data for any of the passwd functions would be
clobbered by the data for any of the group functions (or vice versa).
This might seem like an insufficient fix, but POSIX explicitly says (for
getpwnam) that the result "might be overwritten by a subsequent call to
getpwent(), getpwnam(), or getpwuid()" and likewise for other members of
that group, plus equivalent text for the group-related functions.

Move some pthread functions to signal.h.
POSIX specifies that pthread_kill(3) and pthread_sigmask(3) are
supposed to live in signal.h rather than pthread.h.
Since signal.h now needs pthread_t and pthread_attr_t, I've moved
those defintions into include/machine/pthread_types.h to keep the
namespace clean. I also sorted some includes. The combination of these
two things seems to have exploded into a cascade of missing includes,
so this patch also cleans up all those.

Fix flockfile(3) and friends for stdin/stdout/stderr too.
stdin/stdout/stderr are special; their mutexes are initialized by
__sinit. There's no unit test for this, because __sinit has already
been called by the time the first unit test runs, but you could
reproduce this failure with a trivial main() that calls flockfile
or ftrylockfile on one of the standard streams before otherwise
using stdio.

On LP64, results are going to be in %rax or x0 whether they're 32- or 64-bit,

Fix race condition in timer disarm/delete.
When setting a repeat timer using the SIGEV_THREAD mechanism, it's possible
that the callback can be called after the timer is disarmed or deleted.
This happens because the kernel can generate signals that the timer thread
will continue to handle even after the timer is supposed to be off.
Add two new tests to verify that disarming/deleting doesn't continue to
call the callback.
Modify the repeat test to finish more quickly than before.
Refactor the Counter implementation a bit.

valgrind seems to mess with the stack enough that the kernel will

are two conditions in the kernel code that decides which form to

Inline helpers need to be exported unmangled.
__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization

Use snprintf instead of sprintf.
At -O0, the attribute warning on sprintf is actually triggered (why
doesn't this happen with -Os?!) and promoted to an error by -Werror.
asctime64_r() is a non-standard function, but the IBM docs state that
the buffer is assumed to be at least 26 characters wide, and the
format string does limit to that (assuming a 4 digit year, also
defined by the IBM docs).

Reimplement clock(3) using clock_gettime(3)
Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.
It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

Use the kernel's sa_restorer for aarch64.
gdb was happy with what we had, but libgcc and libunwind weren't.
libgcc is happy with the kernel's restorer (because of the extra nop),
though libunwind looks like it's going to need code changes regardless.
We could make our restorer more like the kernel's one, but why bother
when we can just let the kernel supply the canonical one?

Fix signal trampolines.
* LP32 should use sa_restorer too. gdb expects this, and future (>= 3.15) x86
kernels will apparently stop supporting the case where SA_RESTORER isn't
set.
* gdb and libunwind care about the exact instruction sequences, so we need to
modify the code slightly in a few cases to match what they're looking for.
* gdb also cares about the exact function names (for some architectures),
so we need to use __restore and __restore_rt rather than __sigreturn and
__rt_sigreturn.
* It's possible that we don't have a VDSO; dl_iterate_phdr shouldn't assume
that getauxval(AT_SYSINFO_EHDR) will return a non-null pointer.
This fixes unwinding through a signal handler in gdb for all architectures.
It doesn't fix libunwind for arm and arm64. I'll keep investigating that...

Add pthread_gettid_np and re-expose __get_thread for LP32.
A lot of third-party code calls the private __get_thread symbol,
often as part of a backport of bionic's pthread_rwlock implementation.
Hopefully this will go away for LP64 (since you're guaranteed the
real implementation there), but there are still APIs that take a tid
and no way to convert between a pthread_t and a tid. pthread_gettid_np
is a public API for that. To aid the transition, make __get_thread
available again for LP32.

Ensure __set_errno is still visible on LP32.
The use of the .hidden directive to avoid going via the PLT for
__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different
file).
This change switches the system call stubs over to a new always-hidden
__set_errno_internal and has a visible __set_errno on LP32 just for
binary compatibility with old NDK apps.

Fix pthread_getattr_np for the main thread.
On most architectures the kernel subtracts a random offset to the stack
pointer in create_elf_tables by calling arch_align_stack before writing
the auxval table and so on. On all but x86 this doesn't cause a problem
because the random offset is less than a page, but on x86 it's up to two
pages. This means that our old technique of rounding the stack pointer
doesn't work. (Our old implementation of that technique was wrong too.)
It's also incorrect to assume that the main thread's stack base and size
are constant. Likewise to assume that the main thread has a guard page.
The main thread is not like other threads.
This patch switches to reading /proc/self/maps (and checking RLIMIT_STACK)
whenever we're asked.

Fix <features.h> (_BSD_SOURCE and _GNU_SOURCE).
<features.h> is supposed to take user-settable stuff like _GNU_SOURCE
and _BSD_SOURCE and turn them into __USE_GNU and __USE_BSD for use in
the C library headers. Instead, bionic used to unconditionally define
_BSD_SOURCE and _GNU_SOURCE, and then test _GNU_SOURCE in the header
files (which makes no sense whatsoever).

Add memory ordering constraint, convert to C11 atomics
Add an ordering constraint/fence to __system_property_serial.
This slows down a read on a Nexus 5 from about 50 to about 70 ns,
but avoids the possibility of seeing an inconsistent property value.
Use C11 atomic operations where easy and appropriate.
This code remains not fully C++11 memory model conformant, but
I would now expect the generated code to now be correct with current compilers.

Do a second key cleanup in pthread_exit.
During pthread_exit, the keys are cleaned. Unfortunately, a call to
free occurs after the cleanup and the memory for some of the keys
is recreated when using jemalloc. The solution is to do the key
cleanup twice.
Also, modify the pthread_detach__leak test to be less flaky
when run on a jemalloc system.

Use libunwindbacktrace for debug malloc code.
Create a method of disabling the debug allocation code paths so that
it's possible to use the libunwindbacktrace library without any
modifications.
Use this path to create and destroy the maps for the process. It's not
stricly necessary in the init code since the symbols are not modified
until after the initialize calls.
Also, remove the debug_XXX source files that doesn't need to be in libc.so.
Fix the maps reading code since it was completely broken for 64 bit.

Use vsnprintf(3) in syslog(3).
It seemed like a clever trick to use the internal log message formatting
code in syslog(3), but on reflection that means you can't (for example)
format floating point numbers. This patch switches us over to using good
old vsnprintf(3), even though that requires us to jump through a few hoops.
There's no obvious way to unit test this, so I wrote a little program and
ran that.

Slim down static binaries by avoiding stdio.
It's okay for a program to choose to drag in stdio, but it's unfortunate
if even the minimal "int main() { return 42; }" drags in stdio...
This brings the minimal static binary on ARM down from 78KiB to 46KiB.
Given that we don't have a separate -lpthread it's not obvious to me that
we can shave this down any further. I'm not sure whether this is a worthwhile
change for that reason. (And the fact that dynamic binaries, the usual case,
are unaffected either way.)

Do not include libc_common in malloc debug code.
The inclusion of the static libc_common library in the malloc_debug_XXX.so
shared libraries causes constructors to be called twice. This doesn't seem
to have caused any issues when setting the libc.debug.malloc property.
However, jemalloc crashes because there are two jemalloc implementations,
one in the static libc_common library and one in the shared library. Each
implementation has created overlapping thread keys that are not the same.
The crash comes because one of the jemalloc keys is actually used by the
locale setting code. Thus if someone sets the locale, the jemalloc code
crashes trying to access the same key.

libc_logging: Set SOCK_CLOEXEC on socket
Socket file descriptors remain open across exec unless
SOCK_CLOEXEC is set. Enable this option, to avoid leaking
file descriptors.
In practice, this isn't a big deal, since the socket only remains
open for a very short period to write a message. However, this
socket might leak for for multithreaded programs if an exec occurs
between the open and close.

Fix getpid caching across a clone.
If you make clone, fork, or vfork system calls directly, you're still
on your own, but we now do the right thing for the clone wrapper.
With this implementation, children lose the getpid caching, but we've
no reason to think that that covers any significant use cases.

Cache getpid.
In practice, with this implementation we never need to make a system call.
We get the main thread's tid (which is the same as our pid) back from
the set_tid_address system call we have to make during initialization.
A new pthread will have the same pid as its parent, and a fork child's
main (and only) thread will have a pid equal to its tid, which we get for
free from the kernel before clone returns.
The only time we'd actually have to make a getpid system call now is if
we take a signal during fork and the signal handler calls getpid. (That,
or we call getpid in the dynamic linker while it's still dealing with its
own relocations and hasn't even set up the main thread yet.)

libc: Fix 'index' symbol export.
The C library didn't export the 'index' symbol, but its C++ name-mangling
instead, which broke the ABI and prevented some applications from loading
properly.
The main reason was that the implementation under bionic/index.cpp relied
on the declaration to specify that the function has C linkage.
However, the declaration for index() was removed from both <string.h>
and <strings.h> in a recent patch, which made the compiler think it was
ok to compile the function with C++ linkage instead!
This patch does the following:
- Move index() definition to bionic/ndk_cruft.cpp and ensure it uses
C linkage.
Note that this removes index() from the 64-bit library entirely, this
is intentional and will break source compatibility. Simply replacing
an index() call with the equivalent strchr() should be enough to fix
this in third-party code.
- Remove bionic/index.cpp from the tree and build files.
- Remove x86 assembly implementation from arch-x86/ to avoid conflict
with the one in ndk_cruft.cpp

Revert "Revert "Lose the hand-written futex assembler.""
The problem with the original patch was that using syscall(3) means that
errno can be set, but pthread_create(3) was abusing the TLS errno slot as
a pthread_mutex_t for the thread startup handshake.
There was also a mistake in the check for syscall failures --- it should
have checked against -1 instead of 0 (not just because that's the default
idiom, but also here because futex(2) can legitimately return values > 0).
This patch stops abusing the TLS errno slot and adds a pthread_mutex_t to
pthread_internal_t instead. (Note that for LP64 sizeof(pthread_mutex_t) >
sizeof(uintptr_t), so we could potentially clobber other TLS slots too.)
I've also rewritten the LP32 compatibility stubs to directly reuse the
code from the .h file.
This reverts commit 75c55ff84ebfa686c7ae2cc8ee431c6a33bd46b4.

Register _cleanup function with atexit
* Register cleanup function with atexit
instead of calling it explicitly on
exit()
* abort() no longer calls _cleanup:
Flushing stdio buffers on abort is no
longer required by POSIX.
* dlmalloc no longer need to reset cleanup
(see above)
* Upstream findfp.c makebuf.c setvbuf.cexit.c

Move libstdc++ into libc.
The Android build system always links against libstdc++.so anyway. Having
operator new and operator delete in a separate library means we can't use
constructors and destructors on heap-allocated objects inside the C library,
which is quite an unfortunate limitation.
This will be cheaper too; on LP64 we can stop linking against the [now empty]
libstdc++.so giving the dynamic linker one less library to worry about for
every process.
There's precedent too --- we already have no libpthread or librt.
For now I'm leaving the include files where they are, and I'm generating a
dummy libstdc++.so and libstdc++.a. We can come back and clean that up later
if all goes well.

Switch to a working UTF-8 mb/wc implementation.
Although glibc gets by with an 8-byte mbstate_t, OpenBSD uses 12 bytes (of
the 128 bytes it reserves!).
We can actually implement UTF-8 encoding/decoding with a 0-byte mbstate_t
which means we can make things work on LP32 too, as long as we accept the
limitation that the caller needs to present us with a complete sequence
before we'll process it.
Our behavior is fine when going from characters to bytes; we just
update the source wchar_t** to say how far through the input we got.
I'll come back and use the 4 bytes we do have to cope with byte sequences
split across multiple input buffers. The fact that we don't support
UTF-8 sequences longer than 4 bytes plus the fact that the first byte of
a UTF-8 sequence encodes the length means we shouldn't need the other
fields OpenBSD used (at the cost of some recomputation in cases where a
sequence is split across buffers).
This patch also makes the minimal changes necessary to setlocale(3) to
make us behave like glibc when an app requests UTF-8. (The difference
being that our "C" locale is the same as our "C.UTF-8" locale.)

This replaces a partial set of non-functional functions with a complete
set of functions, all of which actually work.
This requires us to implement mbsnrtowcs and wcsnrtombs which completes
the set of what we need for libc++.
The mbsnrtowcs is basically a copy & paste of wcsnrtombs, but I'm going
to go straight to looking at using the OpenBSD UTF-8 implementation rather
than keep polishing our home-grown turd.
(This patch also opportunistically switches us over to upstream btowc,
mbrlen, and wctob, since they're all trivially expressed in terms of
other functions.)

pthread_once is nice for decoupling, but it makes resource availability less
predictable, which is a bad thing.
This fixes a test failure if uselocale(3) is called before
pthread.pthread_key_create_lots runs.

Remove dead NULL checks from pthread code.
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.)

If the kernel doesn't have MADV_MERGEABLE, stop asking for it.
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).

Fix log_backtrace assertion failure caused by LP64 fix.
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.

Fix 64-bit build.
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.

bionic: fix __set_errno for arm64 syscalls that return a 64-bit value
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.

Also remove sys_signame from LP64. glibc doesn't have this BSD-ism.

Fix 32-bit mmap/mmap64 handling of negative offsets.
We don't actually need to worry about sign extension if we reject
negative values ourselves. Previously it was possible to come up
with negative but aligned values that we would pass to the kernel;
in the case of mmap (as opposed to mmap64) we'd incorrectly turn
those into large positive offsets.

Fix <sys/resource.h>.
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.

Fix compilation of crtbegin.c and pthread_debug.cpp.
Because there was no default := for the aarch64 libc_crt_target_cflags,
the += was causing libc_crt_target_cflags to be recursively-defined
variable, which meant that when we were compiling crtbegin.c LOCAL_PATH
would be bionic/tests/ and we'd have -Ibionic/tests/include/ and find
none of our include files.
Also fix linking of pthread_debug.cpp, at least in the disabled mode.
The enabled mode was already broken for all architectures, and continues
to be broken after this change. It's been broken for long enough that
we might want to just remove it...
(aarch64 is using the FSF linker where arm uses the gold linker.)

Remove harmful attempts to be helpful in pthread_mutex functions.
Most callers won't check for EINVAL, so it's best to fail early.
GCC takes the nonnull attribute as a guarantee that an argument
won't be NULL, so these hacks were already ineffective, which is
how we found that at least one commercial game was using NULL
as if it's a mutex, but actually getting no-op behavior.

Work around CLONE_SETTLS being weird on x86.
Unlike other architectures, on x86 (but not x86-64), CLONE_SETTLS
takes a pointer to a struct user_desc instead of a pointer to the
TLS itself. Rather than have to deal with this here, let's just use
the old __set_tls mechanism we used to use (and still use for the
main thread on all architectures, so it's not going away any time
soon).

Switch to upstream sleep(3) and usleep(3).
Also fix the signature of usleep, and the definition of useconds_t which
should be unsigned, as the 'u' in its name implies.
This patch also cleans up the existing FreeBSD hacks by moving the libm
stuff from <sys/cdefs.h> to a libm-private header, and adding comments
about the hacks we use to build FreeBSD source.

Clean up forking and cloning.
The kernel now maintains the pthread_internal_t::tid field for us,
and __clone was only used in one place so let's inline it so we don't
have to leave such a dangerous function lying around. Also rename
files to match their content and remove some useless #includes.

Fix pthread_join.
Let the kernel keep pthread_internal_t::tid updated, including
across forks and for the main thread. This then lets us fix
pthread_join to only return after the thread has really exited.
Also fix the thread attributes of the main thread so we don't
unmap the main thread's stack (which is really owned by the
dynamic linker and contains things like environment variables),
which fixes crashes when joining with an exited main thread
and also fixes problems reported publicly with accessing environment
variables after the main thread exits (for which I've added a new
unit test).
In passing I also fixed a bug where if the clone(2) inside
pthread_create(3) fails, we'd unmap the child's stack and TLS (which
contains the mutex) and then try to unlock the mutex. Boom! It wasn't
until after I'd uploaded the fix for this that I came across a new
public bug reporting this exact failure.

Clean up the 32-bit kernel support, fix LP64 fcntl declaration.
In practice, thanks to all the registers the stubs don't actually change,
but it's confusing to have an incorrect declaration.
I suspect that fcntl remains broken for aarch64; it happens to work for
x86_64 because the first vararg argument gets placed in the right register
anyway, but I have no reason to believe that's true for aarch64.
This patch adds a unit test, though, so we'll be able to tell when we get
as far as running the unit tests.

<pthread.h> fixes and pthread cleanup.
<pthread.h> was missing nonnull attributes, noreturn on pthread_exit,
and had incorrect cv qualifiers for several standard functions.
I've also marked the non-standard stuff (where I count glibc rather
than POSIX as "standard") so we can revisit this cruft for LP64 and
try to ensure we're compatible with glibc.
I've also broken out the pthread_cond* functions into a new file.
I've made the remaining pthread files (plus ptrace) part of the bionic code
and fixed all the warnings.
I've added a few more smoke tests for chunks of untested pthread functionality.
We no longer need the libc_static_common_src_files hack for any of the
pthread implementation because we long since stripped out the rest of
the armv5 support, and this hack was just to ensure that __get_tls in libc.a
went via the kernel if necessary.
This patch also finishes the job of breaking up the pthread.c monolith, and
adds a handful of new tests.

Explain the sigprocmask in pthread_exit.
Also remove the SIGSEGV special case, which was probably because
hand-written __exit_with_stack_teardown stubs used to try to cause
SIGSEGV if the exit system call returned (which it never does, so
that dead code disappeared).
Also move the sigprocmask into the only case where it's necessary ---
the one where we unmap the stack that would be used by a signal
handler.

Fix the exit syscall stub's name.
I've left the exit_group syscall as _exit because otherwise we'd have to
convince the compiler that our _exit (which just calls __exit_group) is
actually "noreturn", and it seems like that would be less clean than just
cutting out the middleman.
We'll just have to trust ourselves not to add anything to SYSCALLS.TXT
that ought to be private but that only has a single leading underscore.
Hopefully we can manage that.

Fix x86_64 build, clean up intermediate libraries.
The x86_64 build was failing because clone.S had a call to __thread_entry which
was being added to a different intermediate .a on the way to making libc.so,
and the linker couldn't guarantee statically that such a relocation would be
possible.
ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC
This patch addresses that by ensuring that the caller and callee end up in the
same intermediate .a. While I'm here, I've tried to clean up some of the mess
that led to this situation too. In particular, this removes libc/private/ from
the default include path (except for the DNS code), and splits out the DNS
code into its own library (since it's a weird special case of upstream NetBSD
code that's diverged so heavily it's unlikely ever to get back in sync).
There's more cleanup of the DNS situation possible, but this is definitely a
step in the right direction, and it's more than enough to get x86_64 building
cleanly.

Fix __errno for LP64 and clean up __get_tls.
If __get_tls has the right type, a lot of confusing casting can disappear.
It was probably a mistake that __get_tls was exposed as a function for mips
and x86 (but not arm), so let's (a) ensure that the __get_tls function
always matches the macro, (b) that we have the function for arm too, and
(c) that we don't have the function for any 64-bit architecture.

FORTIFY_SOURCE: emphasize prevention in error messages.
FORTIFY_SOURCE prevents buffer overflows from occurring.
However, the error message often implies that we only
detect it, not prevent it.
Bring more clarity to the error messages by emphasizing
prevention over detection.

Daniel Leung <daniel.leung@intel.com> |
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)).

Declare __page_shift and __page_size with C linkage.
__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 mismatch between declaration and forward declaration
KernelArgumentBlock is defined as a class in KernelArgumentBlock.h, but
forward declarations refer to it as a struct.
While this is essentially the same, the mismatch causes a compiler
warning in clang (and may cause warnings in future versions of gcc) in
code that is supposed to be compiled with -Werror.

Optimize __memset_chk, __memcpy_chk. DO NOT MERGE.
This change creates assembler versions of __memcpy_chk/__memset_chk
that is implemented in the memcpy/memset assembler code. This change
avoids an extra call to memcpy/memset, instead allowing a simple fall
through to occur from the chk code into the body of the real
implementation.
Testing:
- Ran the libc_test on __memcpy_chk/__memset_chk on all nexus devices.
- Wrote a small test executable that has three calls to __memcpy_chk and
three calls to __memset_chk. First call dest_len is length + 1. Second
call dest_len is length. Third call dest_len is length - 1.
Verified that the first two calls pass, and the third fails. Examined
the logcat output on all nexus devices to verify that the fortify
error message was sent properly.
- I benchmarked the new __memcpy_chk and __memset_chk on all systems. For
__memcpy_chk and large copies, the savings is relatively small (about 1%).
For small copies, the savings is large on cortex-a15/krait devices
(between 5% to 30%).
For cortex-a9 and small copies, the speed up is present, but relatively
small (about 3% to 5%).
For __memset_chk and large copies, the savings is also small (about 1%).
However, all processors show larger speed-ups on small copies (about 30% to
100%).

Improve stack overflow diagnostics.
We notify debuggerd of problems by installing signal handlers. That's
fine except for when the signal is caused by us running off the end of
a thread's stack and into the guard page.

Fix pthread_getattr_np, pthread_attr_setguardsize, and pthread_attr_setstacksize.
pthread_getattr_np was reporting the values supplied to us, not the values we
actually used, which is kinda the whole point of pthread_getattr_np.
pthread_attr_setguardsize and pthread_attr_setstacksize were reporting EINVAL
for any size that wasn't a multiple of the system page size. This is
unnecessary. We can just round like POSIX suggests and glibc already does.
Also improve the error reporting for pthread_create failures.

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.

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).

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.

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

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.

Handles spurious wake-ups in pthread_join()
Removed 'join_count' from pthread_internal_t and switched to using the flag
PTHREAD_ATTR_FLAG_JOINED to indicate if a thread is being joined. Combined with
a switch to a while loop in pthread_join, this fixes spurious wake-ups but
prevents a thread from being joined multiple times. This is fine for
two reasons:
1) The pthread_join specification allows for undefined behavior when multiple
threads try to join a single thread.
2) There is no thread safe way to allow multiple threads to join a single
thread with the pthread interface. The second thread calling pthread_join
could be pre-empted until the thread is destroyed and its handle reused for
a different thread. Therefore multi-join is always an error.

Clean up abort.
* A dlmalloc usage error shouldn't call abort(3) because we want to
cause a SIGSEGV by writing the address dlmalloc didn't like to an
address the kernel won't like, so that debuggerd will dump the
memory around the address that upset dlmalloc.
* Switch to the simpler FreeBSD/NetBSD style of registering stdio
cleanup. Hopefully this will let us simplify more of the stdio
implementation.
* Clear the stdio cleanup handler before we abort because of a dlmalloc
corruption error. This fixes the reported bug, where we'd hang inside
dlmalloc because the stdio cleanup reentered dlmalloc.

Implement malloc_usable_size for debug impls.
- Implemented chk_memalign.
- Fixed a few bugs in leak_memalign.
- Implemented {leak,fill,check,qemu}_malloc_usable_size.
- Make malloc_usable_size update at run time.
- Add malloc_test.cpp as a small set of tests for the
malloc debug routines.
- Fix the qemu routines since it's been broken since it moved to C++.
- Add support for the %u format to the out_vformat in libc_logging.cpp.
This is used by the emulator code.
Tested using the bionic-unit-tests with setprop libc.debug.malloc
set to 1, 5, and 10.
I tested as much as possible on the emulator, but tracing doesn't appear
to be working properly.

FORTIFY_SOURCE: strcat / strncat optimize
__strcat_chk and __strncat_chk are slightly inefficient,
because they end up traversing over the same memory region
two times.
This change optimizes __strcat_chk / __strncat_chk so they
only access the memory once. Although I haven't benchmarked these
changes, it should improve the performance of these functions.
__strlen_chk - expose this function, even if -D_FORTIFY_SOURCE
isn't defined. This is needed to compile libc itself without
-D_FORTIFY_SOURCE.

Make abort messages available to debuggerd.
This adds __libc_fatal, cleans up the internal logging code a bit more,
and switches suitable callers over to __libc_fatal. In addition to logging,
__libc_fatal stashes the message somewhere that the debuggerd signal handler
can find it before calling abort.
In the debuggerd signal handler, we pass this address to debuggerd so that
it can come back with ptrace to read the message and present it to the user.

Extra logging in pthread_create.
pthread_create returns EAGAIN when it can't allocate a pthread_internal_t,
when it can't allocate a stack for the new thread, or when clone(2) fails
because there are too many threads. It's useful to be able to know why your
pthread_create just failed, so add some logging.

More pthreads cleanup.
POSIX says pthread_create returns EAGAIN, not ENOMEM.
Also pull pthread_attr_t functions into their own file.
Also pull pthread_setname_np into its own file.
Also remove unnecessary #includes from pthread_key.cpp.
Also account for those pthread keys used internally by bionic,
so they don't count against the number of keys available to user
code. (They do with glibc, but glibc's limit is the much more
generous 1024.)
Also factor out the common errno-restoring idiom to reduce gotos.

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.

Don't collect useless stack frames; do demangle C++ symbols.
Previously, we'd collect every stack frame and then throw some away
when we came to log them. This meant that stack traces were effectively
shorter than the buffers that had been allocated for them. This patch
only stores frames we'll actually output.
Also dynamically call the C++ demangler so we don't have to try to
read mangled names. Because no one knows the mangling of operator new[]
for int arrays off the top of their head.

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.

Disable leak checking for mksh; it's way too leaky.
When each shell leaks ~240 allocations, you can't see the leaks from
the program you ran with "adb shell".

Fix the duplication in the debugging code.
We had two copies of the backtrace code, and two copies of the
libcorkscrew /proc/pid/maps code. This patch gets us down to one.
We also had hacks so we could log in the malloc debugging code.
This patch pulls the non-allocating "printf" code out of the
dynamic linker so everyone can share.
This patch also makes the leak diagnostics easier to read, and
makes it possible to paste them directly into the 'stack' tool (by
using relative PCs).
This patch also fixes the stdio standard stream leak that was
causing a leak warning every time tf_daemon ran.

Revert "stack protector: use AT_RANDOM"
The AT_RANDOM changes broke setuid / setgid executables
such as "ping". When the linker executes a setuid program,
it cleans the environment, removing any invalid environment
entries, and adding "NULL"s to the end of the environment
array for each removed variable. Later on, we try to determine
the location of the aux environment variable, and get tripped
up by these extra NULLs.
Reverting this patch will get setuid executables working again,
but getauxval() is still broken for setuid programs because of
this bug.
This reverts commit e3a49a8661125f24aec8a1453e54b3b78005e21e.

stack protector: use AT_RANDOM
Populate the stack canaries from the kernel supplied
AT_RANDOM value, which doesn't involve any system calls.
This is slightly faster (6 fewer syscalls) and avoids
unnecessarily reading /dev/urandom, which depletes entropy.

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.

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 0c11611c11f4dc1b6d43587b72c3ccbe8c51a51c, modified to
work with older versions of GCC still in use on some branches.)

Support GNU_RELRO for static executables.
In 9ec0f03a0d0b17bbb94ac0b9fef6add28a133c3a, we added dynamic
linker support for GNU_RELRO protections. These protections
make certain regions of memory read-only, helping protect certain
data structures from accidental or deliberate modifications.
This change adds GNU_RELRO support to STATIC executables. We can
determine if we're compiled with relro protections by examining
our own program headers, which is passed to us by the kernel
in the AT_PHDR and AT_PHNUM auxiliary vectors.
Parts of this code were stolen from the dynamic linker.

Don't corrupt the thread list if the main thread exits.
...and don't pass a non-heap pointer to free(3), either.
This patch replaces the "node** prev" with the clearer "node* prev"
style and fixes the null pointer dereference in the old code. That's
not sufficient to fix the reporter's bug, though. The pthread_internal_t*
for the main thread isn't heap-allocated --- __libc_init_tls causes a
pointer to a statically-allocated pthread_internal_t to be added to
the thread list.

Fix bug in pthread_join, pthread_exit, pthread_detach
pthread_no_op_detach_after_join test from bionic-unit-tests hangs
on x86 emulator. There is a race in the pthread_join, pthread_exit,
pthread_detach functions:
- pthread_join waits for the non-detached thread
- pthread_detach sets the detached flag on that thread
- the thread executes pthread_exit which just kills the now-detached
thread, without sending the join notification.
This patch improves the test so it fails on ARM too, and modifies
pthread_detach to behave more like glibc, not setting the detach state if
called on a thread that's already being joined (but not returning an error).

Fix a potential NULL pointer dereference in _init_thread().
The first NULL pointer check against `attr' suggests that `attr' can
be NULL. Then later `attr' is directly dereferenced, suggesting the
opposite.
if (attr == NULL) {
...
} else {
...
}
...
if (attr->stack_base == ...) { ... }
The public API pthread_create(3) allows NULL, and interprets it as "default".
Our implementation actually swaps in a pointer to the global default
pthread_attr_t, so we don't need any NULL checks in _init_thread. (The other
internal caller passes its own pthread_attr_t.)

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.

Per-thread -fstack-protector guards for x86.
Based on a pair of patches from Intel:
https://android-review.googlesource.com/#/c/43909/
https://android-review.googlesource.com/#/c/44903/
For x86, this patch supports _both_ the global that ARM/MIPS use
and the per-thread TLS entry (%gs:20) that GCC uses by default. This
lets us support binaries built with any x86 toolchain (right now,
the NDK is emitting x86 code that uses the global).
I've also extended the original tests to cover ARM/MIPS too, and
be a little more thorough for x86.

Make dlerror(3) thread-safe.
I gave up trying to use the usual thread-local buffer idiom; calls to
calloc(3) and free(3) from any of the "dl" functions -- which live in
the dynamic linker -- end up resolving to the dynamic linker's stubs.
I tried to work around that, but was just making things more complicated.
This alternative costs us a well-known TLS slot (instead of the
dynamically-allocated TLS slot we'd have used otherwise, so no difference
there), plus an extra buffer inside every pthread_internal_t.

Avoid malloc lock while calling pthread_atfork.
Expecting the memory in a forked child process to be sane wrt threading
is a bad idea. An example of a problem is when the parent process has
the malloc lock and a child process is forked. The malloc lock in the
child will appear locked by a thread that doesn't exist.
This change aims to make bionic more compatible with glibc by reseting
the malloc lock in the child forked process, as well as holding it
during the fork. This is a feature in dlmalloc 2.8.6 called
LOCK_AT_FORK. In general this feature isn't necessary as a forked
process will then exec. Some bad applications rely on being able to use
features like malloc before the exec and having multiple threads running
in the parent program. This isn't a problem with glibc and this patch
makes it not a problem for bionic.
Unfortunately for use in bionic, LOCK_AT_FORK has an issue as internally
it uses pthread_atfork that in bionic uses malloc. This leads to the
LOCK_AT_FORK initialization deadlocking with pthread_atfork's call to
malloc due to the malloc lock. This change moves the pthread_atfork logic
in LOCK_AT_FORK to be called without the malloc lock held.

Correction to use of TEMP_FAILURE_RETRY in send_prop_msg
RETRY macro may retry command if result is -1. In this
case the command was "connect < 0" instead of just
connect. The comparison will not return -1 and thus
retry is never done. This is now corrected so that
interrupts will cause retry instead of fail.
(There was no other negative side effect of the bug.
The result code from RETRY was used in an if-statement
and it would be true for all negative connect results.
This was according to expectations.)

Adding event logging to libc.
I've basically just copied the relevant bits out of liblog and
EventLog.cpp. While this will let us do the uid logging we want
to address the concerns in 245c07027f78565858dd489eb0d94c3d48743e9d
it doesn't give us much else.

bionic: import heaptracker as chk_malloc
This patch is a rewrite of libc.debug.malloc = 10 (chk_malloc). It provides
the same features as the original (poison freed memory, detect heap overruns
and underruns), except that it provides more debugging information whenever it
detects a problem.
In addition to the original features, the new chk_malloc() implementation
detects multiple frees within a given range of the last N allocations, N being
configurable via the system property libc.debug.malloc.backlog.
Finally, this patch keeps track of all outstanding memory allocations. On
program exit, we walk that list and report each outstanding allocation.
(There is support (not enabled) for a scanner thread periodically walks over
the list of outstanding allocations as well as the backlog of recently-freed
allocations, checking for heap-usage errors.)
Feature overview:
1) memory leaks
2) multiple frees
3) use after free
4) overrun
Implementation:
-- for each allocation, there is a:
1) stack trace at the time the allocation is made
2) if the memory is freed, there is also a stack trace at the point
3) a front and rear guard (fence)
4) the stack traces are kept together with the allocation
-- the following lists and maintained
1) all outstanding memory allocations
3) a backlog of allocations what are freed; when you call free(), instead of
actually freed, the allocation is moved to this backlog;
4) when the backlog of allocations gets full, the oldest entry gets evicted
from it; at that point, the allocation is checked for overruns or
use-after-free errors, and then actually freed.
5) when the program exits, the list of outstanding allocations and the
backlog are inspected for errors, then freed;
To use this, set the following system properties before running the process or
processes you want to inspect:
libc.malloc.debug.backlog # defaults to 100
libc.malloc.debug 10
When a problem is detected, you will see the following on logcat for a multiple
free:

bionic: introduce libc.debug.malloc.program
libc.debug.malloc.program provides an additional level of control over which
processes to enable libc.debug.malloc functionality for. The string value of
libc.debug.malloc.program is matched against the program name; if the value of
libc.debug.malloc.program is a substring of the program name, then malloc debug
is applied to that program at whatever level libc.debug.malloc specifies.
If lib.debug.malloc.program is not specified, then libc.debug.malloc has the
same effect as before.
For example, to enable libc.deubug.malloc = 10 only to the mediaserver, do the
following:
adb root # necessary for setprop
adb setprop libc.debug.malloc.program mediaserver
adb setprop libc.debug.malloc 10
adb kill -9 $(pid mediaserver)

pthread: Invalidate stale stack pointers on pthread_exit()
A call to pthread_key_delete() after pthread_exit() have unmapped the stack of a thread
but before the ongoing pthread_join() have finished executing will result in an access
to unmapped memory.
Avoid this by invalidating the stack_base and tls pointers during pthread_exit().
This is based on the investigation and proprosed solution by

bionic: fix integer overflows in chk_malloc(), leak_malloc(), and leak_memalign()
The allocation size in chk_malloc(), leak_malloc(), and leak_memalign()
functions may be rounded up to a small value, leading to buffer overflows.
The code only runs in debugging mode.
This patch complements commit 6f04a0f4 (CVE-2009-0607).

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).

Initialize TLS before any application code is run.
Since e19d702b8e33, dlsym and friends use recursive mutexes that
require the current thread id, which is not available before the libc
constructor. This prevents us from using dlsym() in .preinit_array.
This change moves TLS initialization from libc constructor to the earliest
possible point - immediately after linker itself is relocated. As a result,
pthread_internal_t for the initial thread is available from the start.
As a bonus, values stored in TLS in .preinit_array are not lost when libc is
initialized.

First commit:
Revert "Revert "am be741d47: am 2f460fbe: am 73b5cad9: Merge "bionic: Fix wrong kernel_id in pthread descriptor after fork()"""

bionic: fix atfork hanlder_mutex deadlock
This cherry-picks commit 34e89c232dd5645fe3b5f9b40856d8e3e4cae57a
After applying the kernel_id fix, the system refused to boot up and we
got following crash log:

Root cause:
The atfork uses the mutex handler_mutex to protect the atfork_head. The
parent will call __bionic_atfork_run_prepare() to lock the handler_mutex,
and need both the parent and child to unlock their own copy of handler_mutex
after fork. At that time, the owner of hanlder_mutex is set as the parent.
If we apply the kernel_id fix, then the child's kernel_id will be set as
child's tid.
The handler_mutex is a recursive lock, and pthread_mutex_unlock(&hander_mutex)
will fail because the mutex owner is the parent, while the current tid
(__get_thread()->kernel_id) is child, not matched with the mutex owner.
At that time, the handler_mutex is left in lock state.If the child wants to
fork other process after than, then it will try to lock handler_mutex, and
then be deadlocked.
Fix:
Since the child has its own copy of vm space from the the parent, the
child space's handler_mutex should be reset to the initialized state.

bionic: fix atfork hanlder_mutex deadlock
After applying the kernel_id fix, the system refused to boot up and we
got following crash log:

Root cause:
The atfork uses the mutex handler_mutex to protect the atfork_head. The
parent will call __bionic_atfork_run_prepare() to lock the handler_mutex,
and need both the parent and child to unlock their own copy of handler_mutex
after fork. At that time, the owner of hanlder_mutex is set as the parent.
If we apply the kernel_id fix, then the child's kernel_id will be set as
child's tid.
The handler_mutex is a recursive lock, and pthread_mutex_unlock(&hander_mutex)
will fail because the mutex owner is the parent, while the current tid
(__get_thread()->kernel_id) is child, not matched with the mutex owner.
At that time, the handler_mutex is left in lock state.If the child wants to
fork other process after than, then it will try to lock handler_mutex, and
then be deadlocked.
Fix:
Since the child has its own copy of vm space from the the parent, the
child space's handler_mutex should be reset to the initialized state.

bionic: Fix wrong kernel_id in pthread descriptor after fork()
After forking, the kernel_id field in the phtread_internal_t returned by pthread_self()
is incorrect --- it's the tid from the parent, not the new tid of the
child.
The root cause is that: currently the kernel_id is set by
_init_thread(), which is called in 2 cases:
(1) called by __libc_init_common(). That happens when the execv( ) is
called after fork( ). But when the zygote tries to fork the android
application, the child application doesn't call execv( ), instread, it
tries to call the Java main method directly.
(2) called by pthread_create(). That happens when a new thread is
created.
For the lead thread which is the thread created by fork(), it should
call execv() but it doesn't, as described in (1) above. So its kernel_id
will inherit the parent's kernel_id.
Fixed it in this patch.

libc: Fix recursive mutex lock implementation.
This fixes a bug that was introduced in the latest pthread optimization.
It happens when a recursive lock is contented by several threads. The main
issue was that the atomic counter increment in _recursive_increment() could
be annihilated by a non-conditional write in pthread_mutex_lock() used to
update the value's lower bits to indicate contention.
This patch re-introduces the use of the global recursive lock in
_recursive_increment(). This will hit performance, but a future patch
will be provided to remove it from the source code.

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).

implement pthread mutex deadlock detection
this works by building a directed graph of acquired
pthread mutexes and making sure there are no loops in
that graph.
this feature is enabled with:
setprop debug.libc.pthread 1
when a potential deadlock is detected, a large warning is
output to the log with appropriate back traces.
currently disabled at compile-time. set PTHREAD_DEBUG_ENABLED=1
to enable.

libc: optimize pthread mutex lock/unlock operations (1/2)
This patch provides several small optimizations to the
implementation of mutex locking and unlocking. Note that
a following patch will get rid of the global recursion
lock, and provide a few more aggressive changes, I
though it'd be simpler to split this change in two parts.
+ New behaviour: pthread_mutex_lock et al now detect
recursive mutex overflows and will return EAGAIN in
this case, as suggested by POSIX. Before, the counter
would just wrap to 0.
- Remove un-necessary reloads of the mutex value from memory
by storing it in a local variable (mvalue)
- Remove un-necessary reload of the mutex value by passing
the 'shared' local variable to _normal_lock / _normal_unlock
- Remove un-necessary reload of the mutex value by using a
new macro (MUTEX_VALUE_OWNER()) to compare the thread id
for recursive/errorcheck mutexes
- Use a common inlined function to increment the counter
of a recursive mutex. Also do not use the global
recursion lock in this case to speed it up.

libc: optimize pthread_once() implementation.
This patch changes the implementation of pthread_once()
to avoid the use of a single global recursive mutex. This
should also slightly speed up the non-common case where
we have to call the init function, or wait for another
thread to finish the call.

Prevent deadlock when using fork
When forking of a new process in bionic, it is critical that it
does not allocate any memory according to the comment in
java_lang_ProcessManager.c:
"Note: We cannot malloc() or free() after this point!
A no-longer-running thread may be holding on to the heap lock, and
an attempt to malloc() or free() would result in deadlock."
However, as fork is using standard lib calls when tracing it a bit,
they might allocate memory, and thus causing the deadlock.
This is a rewrite so that the function cpuacct_add, that fork calls,
will use system calls instead of standard lib calls.

bionic: fix pthread_{create, exit}/signal race condition
(1) in pthread_create:
If the one signal is received before esp is subtracted by 16 and
__thread_entry( ) is called, the stack will be cleared by kernel
when it tries to contruct the signal stack frame. That will cause
that __thread_entry will get a wrong tls pointer from the stack
which leads to the segment fault when trying to access tls content.
(2) in pthread_exit
After pthread_exit called system call unmap(), its stack will be
freed. If one signal is received at that time, there is no stack
available for it.
Fixed by subtracting the child's esp by 16 before the clone system
call and by blocking signal handling before pthread_exit is started.

bionic: Do not use <sys/atomics.h> for platform code.
We're going to modify the __atomic_xxx implementation to provide
full memory barriers, to avoid problems for NDK machine code that
link to these functions.
First step is to remove their usage from our platform code.
We now use inlined versions of the same functions for a slight
performance boost.
+ remove obsolete atomics_x86.c (was never compiled)
NOTE: This improvement was benchmarked on various devices.
Comparing a pthread mutex lock + atomic increment + unlock
we get:
- ARMv7 emulator, running on a 2.4 GHz Xeon:
before: 396 ns after: 288 ns
- x86 emulator in KVM mode on same machine:
before: 27 ns after: 27 ns
- Google Nexus S, in ARMv7 mode (single-core):
before: 82 ns after: 76 ns
- Motorola Xoom, in ARMv7 mode (multi-core):
before: 121 ns after: 120 ns
The code has also been rebuilt in ARMv5TE mode for correctness.

libc: fix the pthread_sigmask implementation
The old code didn't work because the kernel expects a 64-bit sigset_t
while the one provided by our ABI is only 32-bit. This is originally
due to the fact that the kernel headers themselves define sigset_t
as a 32-bit type when __KERNEL__ is not defined (apparently to cater
to libc5 or some similarly old C library).
We can't modify the size of sigset_t without breaking the NDK ABI,
so instead perform runtime translation during the call.

libc: Add logcat error message for memory corruption
Our dlmalloc implementation currently calls abort() when it detects
that the heap is corrupted, or that an invalid pointer is passed to
one of its functions.
The only way to detect this is because abort() will force-fully
crash the current program with a magic fault address of '0xdeadbaad'.
However, this is not really well documented, and a frequent topic
on the android-ndk forum (among others).
This change makes our dlmalloc code dump a simple message to the
log just before the abort() call (and hence before the stack trace)
to better help identify the problem.

do not merge. Move property setting from libcutils to bionic.
Backport I110b653a58f3
All the other property stuff is already here. Property setting was
only in libcutils previously to leverage a utility function / constant
or two.
Unfortunately in the process of fixing a race condition we would've
had to do break abstraction boundaries and put some libc-internal
details into libcutils so instead of that we'll just move this
into bionic.

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.

the functionality is identical. This patch removes the duplicated
_rand48. Also, drand48 and erand48 are modified accordingly.

libc: fix executable destruction support.
This change allows an executable to call its destructor functions
(declared with __attribute__((destructor))) to be properly called
when it normally exits.
Note that this is different from calling the destructors of a shared
library when it is unloaded with dlclose() or through program exit,
which are already supported.

get_malloc_leak_info: Fix assumption that totalMemory out parameter was initialized to zero.
The get_malloc_leak_info() currently asssumes that the totalMemory out parameter
was pre-initialized to zero before the routine is called. If it is not then the
accumulated totalMemory value will be incorrect. It is likely that many callers
will simply allocate totalMemory on the stack with no initialization and assume
that get_malloc_leak_info will set the proper value.
As an example, the caller in frameworks/base/core/jni/android_os_Debug.cpp
calls get_malloc_leak_info() with the address uninitiazed stack variable
for totalMemory. It is probably best to fix this in get_malloc_leak_info.

Add memory barriers to pthread_once.
The implementation was using a double-checked locking approach that
could break on SMP.
In addition to the barriers I also switched to a volatile pointer. I
don't think this will matter unless gcc can conclude that _normal_lock
can't affect *once_control, but I figured it was better to be safe.
(It seems to have no impact whatsoever on the generated code.)

Bulletproof leak dump against null hash entries
Previously, the malloc leak checking code would crash in qsort()
if null entries existed in its bookkeeping table. This change
makes the comparison function detect null entries and sort them
to the end safely.

of static C++ objects contained in shared libraries will happen
properly when dlclose() is called.
Note that this change introduces crtbegin_so.S and crtend_so.S which
are currently ignored by the build system.
+ move definition of __dso_handle to the right place
(before that, all shared libraries used the __dso_handle
global variable from the C library).
Note that we keep a 'weak' __dso_handle in aeabi.c to avoid
breaking the build until the next patch to build/core/combo/
appears. We will be able to remove that later.
+ move bionic/aeabi.c to arch-arm/bionic/ (its proper location)
NOTE: The NDK will need to be modified to enable this feature in
the shared libraries that are generated through it.

... 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.

bionic: pthread: use private futexes by default for mutexes and condvars
Private futexes are a recent kernel addition: faster futexes that cannot be
shared between processes. This patch uses them by default, unless the PROCESS_SHARED
attribute flag is used when creating a mutex and/or conditional variable.
Also introduces pthread_condattr_init/destroy/setpshared/getpshared.

Fix the C library runtime initialization order.
This allows libc.so to run the C runtime initializer as soon as the
dynamic linker loads the shared library, i.e. before any other initializers
(e.g. static C++ constructors in other shared libraries the executable depends
on).
This also removes the bug where the initializers from the executable itself
were run twice: once by the dynamic linker, and another time by __libc_init
as defined by libc_init_dynamic.c

Fix the C library initialization to avoid calling static C++ constructors twice.
The problem was due to the fact that, in the case of dynamic executables,
the dynamic linker calls the DT_PREINIT_ARRAY, DT_INIT and DT_INIT_ARRAY
constructors when loading shared libraries and dynamic executables,
*before* calling the executable's entry point (i.e. arch-$ARCH/bionic/crtbegin_dynamic.c)
which in turns call __libc_init() in libc.so, as defined by bionic/libc_init_dynamic.c
The latter did call these constructors array again, mistakenly.
The patch also updates the documentation of many related functions.
Also adds a new section to linker/README.TXT explaining restrictions on
C library usage.
The patch has been tested on a Dream for stability issues with
proprietary blobs:
- H264 decoding works
- Camera + Video recording works
- GPS works
- Sensors work
The tests in system/extra/tests/bionic/libc/common/test_static_cpp_mutex.cpp has been
run and shows the static C++ constructor being called only once.
