Albert ARIBAUD (3ADEV) ac253355ba Y2038: make __difftime compatible with 64-bit time
Provide a 64-bit-time version of __difftime (but do not assume
__time64_t is a signed int so that Gnulib can reuse the code)
and make the 32-bit version a wrapper of it.

Current difftime expects two time_t arguments and returns a
double. To preserve source-code compatibility, its 64-bit-time
equivalent expects two __time64_t arguments but still returns
a double.

This patch was tested by running 'make check' on branch
master then applying this patch and its two predecessors and
running 'make check' again, and checking that both 'make check'
yield identical results. This was done on x86_64-linux-gnu and
i686-linux-gnu.

This patch was also functionally tested with an ad hoc userland
C program which checks the result of difftime for various pairs
of 32-bit and, for 64-bit builds, of 64-bit time_t values too.
The program was built and run against a glibc with and without
the patch, and the results compared to ensure the patch does
not change the behavior of difftime.

Albert ARIBAUD (3ADEV) 72b8692d7e Y2038: make __tz_convert compatible with 64-bit-time
Now that __time64_t exists, we can switch internal function
__tz_convert from 32-bit to 64-bit time. This involves switching
some other internal functions as well, namely __tz_compute and
__offtime.

Albert ARIBAUD (3ADEV) d51f99ce80 Y2038: Add 64-bit time for all architectures
glibc support for 64-bit time_t on 32-bit architectures
will involve:

- Using 64-bit times inside glibc, with conversions
  to and from 32-bit times taking place as necessary
  for interfaces using such times.

- Adding 64-bit-time support in the glibc public API.
  This support should be dynamic, i.e. glibc should
  provide both 32-bit and 64-bit implementations and
   let user code choose at compile time whether to use
   the 32-bit or 64-bit interfaces.

This requires a glibc-internal name for a type for times
that are always 64-bit.

Based on __TIMESIZE, a new macro is defined, __TIME64_T_TYPE,
 which is always the right __*_T_TYPE to hold a 64-bit-time.
__TIME64_T_TYPE equals __TIME_T_TYPE if __TIMESIZE equals 64
and equals __SQUAD_T_TYPE otherwise.

__time64_t can then replace uses of internal_time_t.

This patch was tested by running 'make check' on branch
master then applying this patch and its predecessor and
running 'make check' again, and checking that both 'make
check' yield identical results. This was done on
x86_64-linux-gnu and i686-linux-gnu.

Paul Eggert e1080e7e5f Fix mktime localtime offset confusion
[BZ #23603]
* include/time.h (__mktime_internal): The localtime offset is now
of type long int instead of time_t.  This is the longstanding type
in glibc, and it is more than enough to represent difference
between localtime and gmtime even if it is 32 bits and time_t is
64.  Changing it now will let us avoid an unnecessary change when
time_t is widened to 64 bits on 32-bit platforms.
* time/mktime-internal.h (mktime_offset_t): Now long int.

H.J. Lu 8bcdb7e0c5 Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.

Size comparison of libc.so:

On x86-64:
        text	   data	    bss	    dec	    hex
Before: 1728577	  20584	  17088	1766249	 1af369
After : 1728593	  20584	  17088	1766265	 1af379

The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.

On i686:
        text	   data	    bss	    dec	    hex
Before: 1869039	  11444	  11112	1891595	 1cdd0b
After : 1868635	  11444	  11112	1891191	 1cdb77

The code size is decreased by avoiding GOT/PLT for hidden functions.

Adhemerval Zanella 2b0b9a1c85 Consolidate remaning non cancellable definitions
This patch consolidate the remaning non cancellable syscall definitions
on not-cancel.h header.  They are:

  * __fcntl_nocancel: Moved from fcntl.h to not-cancel.h.
  * __sigsuspend_nocancel: Removed since 988f991b50 it is not used or
    defined anymore.
  * __nanosleep_nocancel: Removed since 6f33fd046b it is defined on
    not-cancel.h.

Now all non-cancellable syscall definition are defined on not-cancel
(the only exceptions is the stdio symbol __fxprintf_nocancel which
uses non cancellable open and it is used on getopt implementation).

Checked on x86_64-linux-gnu and with build-many-glibc.py.

Adhemerval Zanella fa872e1b62 Clean pthread functions namespaces for C11 threads
This patch adds internal definition (through {libc_}hidden_{proto,def}) and
also change some strong to weak alias for symbols that might be used by C11
threads implementations.

The patchset should not change libc/libpthread functional, although object
changes are expected (since now internal symbols are used instead) and final
exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread
usage of __mmap{64}, __munmap, __mprotect).

Zack Weinberg af85385f31 Use locale_t, not __locale_t, throughout glibc
<locale.h> is specified to define locale_t in POSIX.1-2008, and so are
all of the headers that define functions that take locale_t arguments.
Under _GNU_SOURCE, the additional headers that define such functions
have also always defined locale_t.  Therefore, there is no need to use
__locale_t in public function prototypes, nor in any internal code.

Zack Weinberg f0be25b633 Rename xlocale.h to bits/types/__locale_t.h.
xlocale.h is already a single-type micro-header, defining struct
__locale_struct and the typedefs __locale_t and locale_t.  This patch
brings it into the bits/types/ scheme: there are now
bits/types/__locale_t.h which defines only __locale_struct and
__locale_t, and bits/types/locale_t.h which defines locale_t as well
as the other two.  None of *our* headers need __locale_t.h, but it
appears to me that libstdc++ could make use of it.

There are a lot of external uses of xlocale.h, but all the uses I
checked had an autoconf test or equivalent for its existence.  It has
never been available from other C libraries, and it has always
contained a comment reading "This file is not standardized, don't rely
on it, it can go away without warning" so I think dropping it is
pretty safe.

I also took the opportunity to clean up comments in various public
header files that still talk about the *_l interfaces as though they
were completely nonstandard.  There are a few of them, notably the
strtoX_l and wcstoX_l families, that haven't been standardized, but
the bulk are in POSIX.1-2008.

        * locale/xlocale.h: Rename to...
	* locale/bits/types/__locale_t.h: ...here.  Adjust commentary.
	Only define struct __locale_struct and __locale_t, not locale_t.
        * locale/bits/types/locale_t.h: New file; define locale_t here.
        * locale/Makefile (headers): Update to match.

        * include/xlocale.h: Delete wrapper.
        * include/bits/types/__locale_t.h: New wrapper.
        * include/bits/types/locale_t.h: New wrapper.

        * stdlib/stdlib.h, string/string.h, string/strings.h, time/time.h
        * wcsmbs/wchar.h, wctype/wctype.h: Use bits/types/locale_t.h.
        Correct outdated comments regarding the standardization status of
        the functions that take locale_t arguments.

Zack Weinberg 7c3018f9e4 Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.

There are still quite a few tests that need to see internal gunk of
one variety or another.  For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'.  There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.

There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all.  (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.)  When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.

The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change.  They should be
relatively self-explanatory.  In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.

	* Makerules: New subdir configuration variables 'tests-internal'
	and 'test-internal-extras'.  Test files in these categories will
	still be compiled with MODULE_NAME=nonlib.  Test files in the
	existing categories (tests, xtests, test-srcs, test-extras) are
	now compiled with MODULE_NAME=testsuite.
	New subdir configuration variable 'modules-names-tests'.  Files
	which are in both 'modules-names' and 'modules-names-tests' will
	be compiled with MODULE_NAME=testsuite instead of
	MODULE_NAME=extramodules.
	(gen-as-const-headers): Move to tests-internal.
	(do-tests-clean, common-mostlyclean): Support tests-internal.
	* Makeconfig (built-modules): Add testsuite.
	* Makefile: Change libof-check-installed-headers-c and
	libof-check-installed-headers-cxx to 'testsuite'.
	* Rules: Likewise.  Support tests-internal.
	* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
	Remove extra-modules.mk.

	* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
	PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
	very top of the file and rationalize their order.
	If MODULE_NAME is not defined at all, define IS_IN to always be
	false, and don't define _ISOMAC.
	If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
	true, define _ISOMAC and suppress everything else in this file,
	starting with the inclusion of config.h.
	Do check for inappropriate definitions of __OPTIMIZE__ and
	__FAST_MATH__ here, but only if _ISOMAC is not defined.
        Correct some out-of-date commentary.

	* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
	and _Mlong_double_ before including math.h.

	_STRING_ARCH_unaligned. Move a comment to a more appropriate
	location.

	* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
	* include/time.h, include/unistd.h, include/wchar.h: No need to

	* stdlib/tst-strtod5.c: Convert to test-driver and add copyright notice.
        Split tests of __strtod_internal to...
	* stdlib/tst-strtod5i.c: ...this new file.
	* string/test-string.h: Include stdint.h. Duplicate definition of

Florian Weimer 8492c4dd69 timezone: Remove TZNAME_MAX limit from sysconf [BZ #15576]

Zack Weinberg 05b68e14b1 Installed-header hygiene (BZ#20366): time.h types.
Many headers are expected to expose a subset of the type definitions
in time.h.  time.h has a whole bunch of messy logic for conditionally
defining some its types and structs, but, as best I can tell, this
has never worked 100%.  In particular, __need_timespec is ineffective
if _TIME_H has already been defined, which means that if you compile

  #include <time.h>
  #include <sched.h>

with e.g. -fsyntax-only -std=c89 -Wall -Wsystem-headers, you will get

In file included from test.c:2:0:
/usr/include/sched.h:74:57: warning: "struct timespec" declared inside
  parameter list will not be visible outside of this definition or declaration
 extern int sched_rr_get_interval (__pid_t __pid, struct timespec *__t) __THROW;
                                                         ^~~~~~~~

And if you want to _use_ sched_rr_get_interval in a TU compiled that
way, you're hosed.

This patch replaces all of that with small bits/types/TYPE.h headers
as introduced earlier.  time.h and bits/time.h are now *much* simpler,
and a lot of other headers are slightly simpler.

	* time/time.h, bits/time.h, sysdeps/unix/sysv/linux/bits/time.h:
	Remove all logic conditional on __need macros.  Move all the
	conditionally defined types to their own headers...
	* time/bits/types/clock_t.h: Define clock_t here.
	* time/bits/types/clockid_t.h: Define clockid_t here.
	* time/bits/types/struct_itimerspec.h: Define struct itimerspec here.
	* time/bits/types/struct_timespec.h: Define struct timespec here.
	* time/bits/types/struct_timeval.h: Define struct timeval here.
	* time/bits/types/struct_tm.h: Define struct tm here.
	* time/bits/types/time_t.h: Define time_t here.
	* time/bits/types/timer_t.h: Define timer_t here.
	* time/Makefile: Install the new headers.

	* bits/resource.h, io/fcntl.h, io/sys/poll.h, io/sys/stat.h
	* io/utime.h, misc/sys/select.h, posix/sched.h, posix/sys/times.h
	* posix/sys/types.h, resolv/netdb.h, rt/aio.h, rt/mqueue.h
	* signal/signal.h, pthread/semaphore.h, sysdeps/nptl/pthread.h
	* sysdeps/unix/sysv/linux/alpha/bits/resource.h
	* sysdeps/unix/sysv/linux/alpha/sys/acct.h
	* sysdeps/unix/sysv/linux/bits/resource.h
	* sysdeps/unix/sysv/linux/bits/timex.h
	* sysdeps/unix/sysv/linux/mips/bits/resource.h
	* sysdeps/unix/sysv/linux/net/ppp_defs.h
	* sysdeps/unix/sysv/linux/sparc/bits/resource.h
	* sysdeps/unix/sysv/linux/sys/acct.h
	* sysdeps/unix/sysv/linux/sys/timerfd.h
	* sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h
	* time/sys/time.h, time/sys/timeb.h
	Use the new bits/types headers.

	* include/time.h: Remove __need logic.
	* include/bits/time.h
	* include/bits/types/clock_t.h, include/bits/types/clockid_t.h
	* include/bits/types/time_t.h, include/bits/types/timer_t.h
	* include/bits/types/struct_itimerspec.h
	* include/bits/types/struct_timespec.h
	* include/bits/types/struct_timeval.h
	* include/bits/types/struct_tm.h:
	New wrapper headers.
