99c393dff3 Fix the order of arguments to sys_clone for x86.
Unlike x86-64, x86's arguments are just like every other
architecture's.

80906141f7 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).

363390eaff Move arm user.h definitions to sys/user.h.
There is no uapi user.h file for arm, it was included by accident.
Move the user struct definition into the file to follow the pattern
used by the other architectures.

ab61eb366a 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.

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.

877ec6d904 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.

652289942d bionic: call stdio cleanup on exit
As of 61e699a133, stdio clean up
functions are no longer registered in atexit and must be called
manually via __cleanup.

The issue this fixes is some static binaries linked against bionic
cannot output properly when piped or redirected because the buffer
is not flushed before closing.

This is done by pulling in exit.c (and other dependencies) from
netbsd.

The simplest workaround is to handle the indirection in userland and then
call the required system call directly.

2ecc164ae9 Remove the dependency on the non-uapi __kernel_nlink_t.
The kernel doesn't have an nlink_t; it just uses the equivalent of
uint32_t. We already had a usable __nlink_t in the C library, so
let's just define our nlink_t in terms of __nlink_t, which is what
__nlink_t was meant for anyway.

Note that our struct stat just follows the kernel, and doesn't refer
to nlink_t anyway.

062092543f 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.

The old code ignored operator precedence (!), despite having two tables
of operator precedence. The code's still pretty awful, but I've cleaned
it up enough to fix this, the most important bug.

This patch lets us correctly clean the uapi unistd.h, stat.h, and swab.h files,
and also fixes the mess we were already making of various old kernel
header files. I've added a bunch more tests, fixed the existing tests that
the existing script was already failing (!), and changed the script so that
the tests are run every time the script is run.

We can probably remove some of the old kernel header files that we were
parsing incorrectly, but we can worry about that later.

c3f114037d <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.

2b6e43e00e 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.

From the release notes:

  Changes affecting current and future time stamps:

    Libya has switched its time zone back to UTC+2 without DST,
    instead of UTC+1 with DST.  (Thanks to Even Scharning.)

    Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.
    (Thanks to Gwillim Law.)

  Changes affecting future time stamps:

    Acre and (we guess) western Amazonas will switch from UTC-4 to UTC-5
    on 2013-11-10.  This affects America/Rio_Branco and America/Eirunepe.
    (Thanks to Steffen Thorsen.)

    Add entries for DST transitions in Morocco in the year 2038.
    This avoids some year-2038 glitches introduced in 2013g.
    (Thanks to Yoshito Umaoka for reporting the problem.)

6b53c2349a 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.

a long time ago, but never followed through with the removal of what
was then confusingly called "stub" and was recently renamed "custom".

scheduling for all their threads, and the kernel says "don't be

ac6bc31942 Remove new aligned memcpy path for cortex-a15.
For some reason the new cortex-a15 memcpy code from ARM is really bad
for really large copies. This change forces us to go down the old path
for all copies.

All of my benchmarks show the new version is faster for large copies, but
something is going on that I don't understand.

This causes a perf degradation for copies bigger than will fit in the cache.
Fixing this back to the original * 8. I tried other multiples, but * 8 is th
sweet spot on krait.

Also, let's test the return side of these calls, not just the

6e38072add Wrap sprintf()/snprintf() macros to prevent expansion errors.
Previously, FORTIFY_SOURCE used single macros to define these standard
functions for use with clang. This can cause conflicts with other macros used
to call these functions, particularly when those macros expand the number of
arguments to the function. This change wraps our macro definitions, so that
expansion properly takes place for programmer arguments first.

Warnings are errors for all home-grown bionic code, and the arch-specific
code now counts as home-grown bionic code (it was mistakenly counted as
"not ours" before).

eb847bc866 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.

2a0b873065 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.

In c++11, register has been deprecated, and
libc is now built as gnu++11

From the documentation:
A register specifier is a hint to the implementation
that the variable so declared will be heavily used.
[ Note: The hint can be ignored and in most implementations
it will be ignored if the address of the variable is taken.
This use is deprecated (see D.2)

  Changes affecting time stamps before 1970

    Pacific/Johnston is now a link to Pacific/Honolulu.  This corrects
    some errors before 1947.

    Some zones have been turned into links, when they differ from
    existing zones only in older data that was likely invented or that
    differs only in LMT or transition from LMT.  These changes affect
    only time stamps before 1943.  The affected zones are:
    Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
    America/Grenada, America/Guadeloupe, America/Marigot,
    America/Montserrat, America/St_Barthelemy, America/St_Kitts,
    America/St_Lucia, America/St_Thomas, America/St_Vincent,
    America/Tortola, and Europe/Vaduz.  (Thanks to Alois Treindl for
    confirming that the old Europe/Vaduz zone was wrong and the new
    link is better for WWII-era times.)

    Change Kingston Mean Time from -5:07:12 to -5:07:11.  This affects
    America/Cayman, America/Jamaica and America/Grand_Turk time stamps
    from 1890 to 1912.

    Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
    This affects Europe/Zurich time stamps from 1853 to 1894.  (Thanks
    to Alois Treindl).

    Change the date of the circa-1850 Zurich transition from 1849-09-12
    to 1853-07-16, overriding Shanks with data from Messerli about
    postal and telegraph time in Switzerland.

  Data changes affecting behavior of tzselect and similar programs

    Country code BQ is now called the more-common name "Caribbean Netherlands"
    rather than the more-official "Bonaire, St Eustatius & Saba".

    Remove from zone.tab the names America/Montreal, America/Shiprock,
    and Antarctica/South_Pole, as they are equivalent to existing
    same-country-code zones for post-1970 time stamps.  The data for
    these names are unchanged, so the names continue to work as before.

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.

7e841ed688 Remove useless x86 fallbacks.
The NDK ABI requires that you support SSE2, and the build system won't let you
build with ARCH_X86_HAVE_SSE2 set to false. So let's stop pretending this
constant is actually a variable, and let's remove the corresponding dead code.

Also, the USE_SSE2 and USE_SSE3 macros are unused, so let's not bother
setting them.

it set unconditionally to 32 sounds like a bad idea.

d3e64a3f40 Add x86_64 to the bionic headers.
Manual changes:

  cpp.py: cope with macros that refer to other macros.

  defaults.py: x86 no longer always implies __i386__; use __i386__ to replace
  the kernel CONFIG_X86_32 flag.

  asm/page.h: the upstream page.h isn't a uapi header and no longer includes
  the stuff we were using it for. Let's just have our own static file, since
  it's the same for all our architectures (both 32- and 64-bit).

  sys/select.h: we used to use the various FD_SET-related macros from the
  kernel header files, but they've gone. Adjust by adding trivial equivalent
  definitions.

Automated changes:

  libc/kernel/arch-x86, libc/kernel/common: regenerated from
  external/kernel-headers.

d13c2b1ba6 Fix unnecessary call to __strncpy_chk2
If "n" is smaller than the size of "src", then we'll
never read off the end of src. It makes no sense to call
__strncpy_chk2 in those circumstances.

For example, consider the following code:

int main() {
  char src[10];
  char dst[5];
  memcpy(src, "0123456789", sizeof(src));
  strncpy(dst, src, sizeof(dst));
  dst[4] = '\0';
  printf("%s\n", dst);
  return 0;
}

In this code, it's clear that the strncpy will never read off
the end of src.

localtime.c and strftime.c are still quite different from upstream because of

From the tzcode2013e release notes:

  Changes affecting Godthab time stamps after 2037 if version mismatch

    Allow POSIX-like TZ strings where the transition time's hour can
    range from -167 through 167, instead of the POSIX-required 0
    through 24.  E.g., TZ='FJT-12FJST,M10.3.1/146,M1.3.4/75' for the
    new Fiji rules.  This is a more-compact way to represent
    far-future time stamps for America/Godthab, America/Santiago,
    Antarctica/Palmer, Asia/Gaza, Asia/Hebron, Asia/Jerusalem,
    Pacific/Easter, and Pacific/Fiji.  Other zones are unaffected by
    this change.  (Derived from a suggestion by Arthur David Olson.)

    Allow POSIX-like TZ strings where daylight saving time is in
    effect all year.  E.g., TZ='WART4WARST,J1/0,J365/25' for Western
    Argentina Summer Time all year.  This supports a more-compact way
    to represent the 2013d data for America/Argentina/San_Luis.
    Because of the change for San Luis noted above this change does not
    affect the current data.  (Thanks to Andrew Main (Zefram) for
    suggestions that improved this change.)

    Where these two TZ changes take effect, there is a minor extension
    to the tz file format in that it allows new values for the
    embedded TZ-format string, and the tz file format version number
    has therefore been increased from 2 to 3 as a precaution.
    Version-2-based client code should continue to work as before for
    all time stamps before 2038.  Existing version-2-based client code
    (tzcode, GNU/Linux, Solaris) has been tested on version-3-format
    files, and typically works in practice even for time stamps after
    2037; the only known exception is America/Godthab.

  Changes affecting API

    Support for floating-point time_t has been removed.
    It was always dicey, and POSIX no longer requires it.
    (Thanks to Eric Blake for suggesting to the POSIX committee to
    remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
    Heninger, Arthur David Olson, and Alois Treindl, for reporting
    bugs and elucidating some of the corners of the old floating-point
    implementation.)

    The signatures of 'offtime', 'timeoff', and 'gtime' have been
    changed back to the old practice of using 'long' to represent UT
    offsets.  This had been inadvertently and mistakenly changed to
    'int_fast32_t'.  (Thanks to Christos Zoulos.)

    The code avoids undefined behavior on integer overflow in some
    more places, including gmtime, localtime, mktime and zdump.

  Changes affecting code internals

    Minor changes pacify GCC 4.7.3 and GCC 4.8.1.

  Changes affecting documentation and commentary

    Documentation and commentary is more careful to distinguish UT in
    general from UTC in particular.  (Thanks to Steve Allen.)

From the tzcode2013f release notes:

  Changes affecting API

    The types of the global variables 'timezone' and 'altzone' (if present)
    have been changed back to 'long'.  This is required for 'timezone'
    by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
    These variables were originally 'long' in the tz code, but were
    mistakenly changed to 'time_t' in 1987; nobody reported the
    incompatibility until now.  The difference matters on x32, where
    'long' is 32 bits and 'time_t' is 64.  (Thanks to Elliott Hughes.)

  Changes affecting near-future time stamps

    Tocantins will very likely not observe DST starting this spring.
    (Thanks to Steffen Thorsen.)

    Jordan will likely stay at UTC+3 indefinitely, and will not fall
    back this fall.

    Palestine will fall back at 00:00, not 01:00.  (Thanks to Steffen Thorsen.)

    (Thanks to David Wheeler for the heads-up.)  For now, guess that
    Fiji will continue to spring forward the Sunday before the fourth
    Monday in October.

  Changes affecting time stamps before 1970

    Pacific/Johnston is now a link to Pacific/Honolulu.  This corrects
    some errors before 1947.

    Some zones have been turned into links, when they differ from
    existing zones only in older data that was likely invented or that
    differs only in LMT or transition from LMT.  These changes affect
    only time stamps before 1943.  The affected zones are:
    Africa/Juba, America/Anguilla, America/Aruba, America/Dominica,
    America/Grenada, America/Guadeloupe, America/Marigot,
    America/Montserrat, America/St_Barthelemy, America/St_Kitts,
    America/St_Lucia, America/St_Thomas, America/St_Vincent,
    America/Tortola, and Europe/Vaduz.  (Thanks to Alois Treindl for
    confirming that the old Europe/Vaduz zone was wrong and the new
    link is better for WWII-era times.)

    Change Kingston Mean Time from -5:07:12 to -5:07:11.  This affects
    America/Cayman, America/Jamaica and America/Grand_Turk time stamps
    from 1890 to 1912.

    Change the UT offset of Bern Mean Time from 0:29:44 to 0:29:46.
    This affects Europe/Zurich time stamps from 1853 to 1894.  (Thanks
    to Alois Treindl).

    Change the date of the circa-1850 Zurich transition from 1849-09-12
    to 1853-07-16, overriding Shanks with data from Messerli about
    postal and telegraph time in Switzerland.

  Data changes affecting behavior of tzselect and similar programs

    Country code BQ is now called the more-common name "Caribbean Netherlands"
    rather than the more-official "Bonaire, St Eustatius & Saba".

    Remove from zone.tab the names America/Montreal, America/Shiprock,
    and Antarctica/South_Pole, as they are equivalent to existing
    same-country-code zones for post-1970 time stamps.  The data for
    these names are unchanged, so the names continue to work as before.

Daniel Leung
afcc0cccda 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)).

9ae59c02ca 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.

edad1e1558 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.

883ef2499c __memcpy_chk: Fix signed cmp of unsigned values.
I accidentally did a signed comparison of the size_t values passed in
for three of the _chk functions. Changing them to unsigned compares.

Add three new tests to verify this failure is fixed.
