c9123888d8 Update copyright dates not handled by scripts/update-copyrights.
I've updated copyright dates in glibc for 2019.  This is the patch for
the changes not generated by scripts/update-copyrights and subsequent
build / regeneration of generated files.

Please remember to include 2019 in the dates for any new files added
in future (which means updating any existing uncommitted patches you
have that add new files to use the new copyright dates in them).

b50dd3bc8c malloc: Always call memcpy in _int_realloc [BZ #24027]
This commit removes the custom memcpy implementation from _int_realloc
for small chunk sizes.  The ncopies variable has the wrong type, and
an integer wraparound could cause the existing code to copy too few
elements (leaving the new memory region mostly uninitialized).
Therefore, removing this code fixes bug 24027.

0b9c84906f riscv: Use __has_include__ to include <asm/syscalls.h> [BZ #24022]

    riscv: add asm/unistd.h UAPI header

    Marcin Juszkiewicz reported issues while generating syscall table for riscv
    using 4.20-rc1. The patch refactors our unistd.h files to match some other
    architectures.

    - Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
    - Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
    - Adjust kernel asm/unistd.h

    So now asm/unistd.h UAPI header should show all syscalls for riscv.

<asm/syscalls.h> may be restored by

Subject: [PATCH] riscv: restore asm/syscalls.h UAPI header
Date: Tue, 11 Dec 2018 09:09:35 +0100

UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header,
which did resolve issue with missing syscalls macros resulting in
glibc (2.28) build failure. It also broke glibc in a different way:
asm/syscalls.h is being used by glibc. I noticed this while doing
Fedora 30/Rawhide mass rebuild.

The patch returns asm/syscalls.h header and incl. it into asm/unistd.h.
I plan to send a patch to glibc to use asm/unistd.h instead of
asm/syscalls.h

In the meantime, we use __has_include__, which was added to GCC 5, to
check if <asm/syscalls.h> exists before including it.  Tested with
build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7.

989182c40a Multiple locales: Use the correct 12-hour time formats (bug 10496).
It has been discovered that some locales use the 12-hour time formats but
do not use any AM/PM indicator thus making the time ambiguous.  This
commit adds "%p" wherever it was missing.  In some cases it has been
identified that a locale should use 24-hour time format rather than
12-hour.  All time formats come from CLDR but this commit introduces as
few changes as possible (for example, it tries not to change the time zone
display).  For the locales which are not supported by CLDR the consistency
with similar locales (which means the same language or the same country)
has been preserved: if the time formats were the same before the change
then they are still the same after the change.

The time format updates can be roughly summarized as follows:

* Most of the locales of Djibouti, Eritrea, and Ethiopia now use
"%l:%M:%S %p".
* Most of the locales of India and some surrounding countries (Bangladesh,
Nepal etc.) now use "%I:%M:%S %p %Z".
* Most of the Arabic locales now use "%Z %I:%M:%S %p".
* Ge'ez language (Eritrea and Ethiopia) now uses "%l:%M:%S፡%p" (note the
consistent use of Ethiopic wordspace character).
* Tamil (India) now uses "%p %I:%M:%S %Z".
* Chinese (Hong Kong) t_fmt now uses "%p %I<U6642>%M<U5206>%S<U79D2> %Z".
* Additionally, the following locales have been switched from 12-hour time
formats to 24-hour, according to CLDR: Arabic (Morocco), Maltese, Somali
(Kenya), and Tamil (Sri Lanka).
* Finally, the Bulgarian, Czech, and Slovak locales used 24-hour time
format correctly but their t_fmt_ampm field was not empty containing
12-hour time format which was incorrect so it is now replaced with an
empty string.

27841a7d5a sq_AL: Use the correct date and time formats (bug 10496, 23724).
Albanian locale uses the 12-hour clock but some time formats did not
use any AM/PM indicator making the time ambiguous.  This commit adds
"%p" wherever it was missing.

It also sets the correct date format because the old "%Y-%b-%d" produced
rather weird results like "2018-Sht-28".

All time formats come from CLDR but as few changes have been introduced
by this commit as possible.  Some articles from MSDN and other available
online sources have been also taken into account.

57b3ff8e1a Update nios2, sparc32 localplt.data for difftime changes (bug 24023).
The recent difftime changes introduced localplt test failures on nios2
and sparc32, two configurations where some soft-fp functions are
defined in / exported from libc.so, and where the difftime changes
affected the particular set of floating-point operations used in
libc.so.  This patch adds those functions to localplt.data, alongside
other such functions already there.  (In the sparc32 case, and more
generally on any platform where long double is a software
floating-point type, it would probably be more efficient to avoid
using long double at all in difftime, but that's a pre-existing
issue.)

Tested with build-many-glibcs.py for its nios2 and sparcv9
configurations.

5d025ea617 Update longlong.h.
This patch updates longlong.h from GCC.  There were no local changes
in glibc (the previous version was identical to the r232143 GCC
version, apart from copyright dates which had been updated in both
places), so this patch makes it identical to the version in GCC again.

Tested for x86_64 and x86.  Also tested with build-many-glibcs.py for
its RISC-V configurations, as the glibc architecture with the most
substantial changes in longlong.h in this patch.

	* stdlib/longlong.h: Update from GCC.

192963be49 Require GCC 5 or later to build glibc (bug 23993).
We know that building glibc with GCC 4.9 is broken on various
platforms (bug 23993).  As it's more than a year since we last
increased the minimum GCC version to build glibc, this patch changes
the requirement to be GCC 5 or later (indeed, based on 4.9 having been
required for building 2.26, it would be consistent in terms of timing
to require GCC 6 or later from the 2.30 release onwards).  It
deliberately just updates the configure test and corresponding
documentation, leaving removal of no-longer-needed __GNUC_PREREQ tests
for a separate patch.

In the NEWS entry, the requirement for a newer GCC version for
powerpc64le is reiterated (as in the entry for the 4.9 requirement in
2.26) to avoid suggesting the version requirement there has gone down.
(If that version goes up further as part of support for binary128 long
double, of course the wording would change at that time.)

Tested for x86_64.

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.

* include/time.h (__difftime64): Add.
* time/difftime.c (subtract): convert to 64-bit time.
* time/difftime.c (__difftime64): Add.
* time/difftime.c (__difftime): Wrap around __difftime64.

da75c1b180 Remove x86 mathinline.h.
After previous cleanups, the only code in the x86 bits/mathinline.h
that is relevant with current compilers is the inline of
__ieee754_atan2l that is conditional on __LIBC_INTERNAL_MATH_INLINES
(i.e. for when libm itself is being built).

This inline is something that does belong in glibc not GCC, since
__ieee754_atan2l is a purely internal function name.  This patch moves
that inline to a new sysdeps/x86/fpu/math_private.h, removing the
bits/mathinline.h header.

Note that previously the inline was only for non-SSE 32-bit x86.  That
condition does not make sense, however, for a long double function; if
it's not inlined, exactly the same x87 instruction will end up getting
used by the out-of-line function, for both 32-bit and 64-bit.  So that
condition is not retained in the new version.

Tested for x86_64 and x86.  As expected, installed stripped shared
libraries are unchanged for 32-bit x86, but installed stripped libm.so
is changed for x86_64 because calls to __ieee754_atan2l start being
inlined where previously they were out of line calls.  (The same
change to start inlining the function would presumably also apply for
32-bit built with -mfpmath=sse, but that's not a configuration I've
tested.)

	* sysdeps/x86/fpu/math_private.h: New file.
	* sysdeps/x86/fpu/bits/mathinline.h: Remove.

515f463f52 Remove x86 mathinline.h sinh, cosh, tanh inlines.
Continuing the removal of bits/mathinline.h inlines that would better
be done by the compiler, this patch removes x86 inlines for sinh, cosh
and tanh functions (inlines only previously present for fast-math,
non-SSE 32-bit x86).  I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88556> for adding such
inlines as an optimization in GCC.

I believe the only remaining part of the x86 bits/mathinline.h that
does anything useful with current compilers after this patch is the
__LIBC_INTERNAL_MATH_INLINES inline of __ieee754_atan2l; I intend to
remove the whole header and move that inline to a sysdeps
math_private.h header in a subsequent patch.

Tested for x86_64 and x86.

	* sysdeps/x86/fpu/bits/mathinline.h (sinh): Remove inline
	definition.
	(cosh): Likewise.
	(tanh): Likewise.

1616d034b6 Print cache size and geometry auxv types on LD_SHOW_AUXV=1
Add support for AT_L1I_CACHESIZE, AT_L1I_CACHEGEOMETRY,
AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY, AT_L2_CACHESIZE,
AT_L2_CACHEGEOMETRY, AT_L3_CACHESIZE and AT_L3_CACHEGEOMETRY when
LD_SHOW_AUXV=1.

AT_L*_CACHESIZE is printed as decimal and represent the number of
bytes of the cache.

AT_L*_CACHEGEOMETRY is treated in order to specify the cache line size
and its associativity.

Example output from a POWER8:

AT_L1I_CACHESIZE:     32768
AT_L1I_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L1D_CACHESIZE:     65536
AT_L1D_CACHEGEOMETRY: 128B line size, 8-way set associative
AT_L2_CACHESIZE:      524288
AT_L2_CACHEGEOMETRY:  128B line size, 8-way set associative
AT_L3_CACHESIZE:      8388608
AT_L3_CACHEGEOMETRY:  128B line size, 8-way set associative

Some of the new types are longer than the previous ones, requiring to
increase the indentation in order to keep the values aligned.

	* elf/dl-sysdep.c (auxvars): Add AT_L1I_CACHESIZE,
	AT_L1I_CACHEGEOMETRY, AT_L1D_CACHESIZE, AT_L1D_CACHEGEOMETRY,

	AT_L3_CACHEGEOMETRY.  Fix indentation when printing the other
	fields.
	(_dl_show_auxv): Give a special treatment to
	AT_L1I_CACHEGEOMETRY, AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY
	and AT_L3_CACHEGEOMETRY.
	* sysdeps/powerpc/dl-procinfo.h (cache_geometry): New function.
	(_dl_procinfo): Fix indentation when printing AT_HWCAP and
	AT_HWCAP2.  Add support for AT_L1I_CACHEGEOMETRY,
	AT_L1D_CACHEGEOMETRY, AT_L2_CACHEGEOMETRY and AT_L3_CACHEGEOMETRY.

56b98bf1fb alpha: Use Linux generic sigaction implementation
Alpha rt_sigaction syscall uses a slight different kernel ABI than
generic one:

arch/alpha/kernel/signal.c

 90 SYSCALL_DEFINE5(rt_sigaction, int, sig, const struct sigaction __user *, act,
 91                 struct sigaction __user *, oact,
 92                 size_t, sigsetsize, void __user *, restorer)

Similar as sparc, the syscall expects a restorer function.  However
different than sparc, alpha defines the restorer as the 5th argument
(sparc defines as the 4th).

This patch removes the arch-specific alpha sigaction implementation,
adapt the Linux generic one to different restore placements (through

43a45c2d82 m68k: Fix sigaction kernel definition (BZ #23960)
Commit b4a5d26d88 (linux: Consolidate sigaction implementation) added
a wrong kernel_sigaction definition for m68k, meant for __NR_sigaction
instead of __NR_rt_sigaction as used on generic Linux sigaction
implementation.  This patch fixes it by using the Linux generic
definition meant for the RT kernel ABI.

Checked the signal tests on emulated m68-linux-gnu (Aranym).  It fixes
the faulty signal/tst-sigaction and man works as expected.

646ce7e0be Remove __ASSUME_ST_INO_64_BIT.
kernel-features.h has a macro __ASSUME_ST_INO_64_BIT, with a comment
"However, SH is lame, and still does not have a 64-bit inode field.".

The macro is, in fact, defined to 0 by Alpha as well as SH.  The Alpha
case is, however, trivially useless: none of the files that test
__ASSUME_ST_INO_64_BIT are built for Alpha (which gained kernel
support for stat64 syscalls, with a 64-bit st_ino field, in Linux
2.6.4; the define to 0 for Alpha in glibc predates that).

The SH kernel gained support for a 64-bit st_ino in struct stat64 in
commit 760bcb1deec13c50e20399c84cb6a8ea41cc2820 ("sh: Fix fstatat64()
syscall."), which is in Linux 2.6.22 and later.  So the redefinition
of __ASSUME_ST_INO_64_BIT to 0 is of no use for SH either; three of
the files testing it do so immediately after a stat64-family syscall
has been used, which will always have set the 64-bit st_ino correctly
(in addition to the 32-bit __st_ino), while the relevant code
__xstat32_conv executes only after such a syscall in the function
calling __xstat32_conv.

Thus this patch removes __ASSUME_ST_INO_64_BIT and code testing it.
Removing the useless [!__ASSUME_ST_INO_64_BIT] code in __xstat32_conv
renders the [_HAVE_STAT64___ST_INO] and [!_HAVE_STAT64___ST_INO] cases
around it identical, so that conditional is also removed.

Tested compilation with build-many-glibcs.py for its Alpha and SH
configurations; also ran the glibc testsuite for x86_64 and x86.

	* sysdeps/unix/sysv/linux/kernel-features.h
	(__ASSUME_ST_INO_64_BIT): Remove macro definition.

80190d2b0e S390: Cleanup ifunc-resolve.h.
The ifunc macros s390_vx_libc* are no longer used and
can be removed as all users are now relying on
s390_libc_ifunc_expr.

The same applies to s390_libc_ifunc.  The macro
s390_libc_ifunc_init is now renamed to
s390_libc_ifunc_expr_stfle_init and the users are
adjusted accordingly.

ChangeLog:

	* sysdeps/s390/multiarch/ifunc-resolve.h
	(s390_vx_libc_ifunc, s390_vx_libc_ifunc_redirected,
	s390_vx_libc_ifunc2, s390_vx_libc_ifunc_init,
	s390_vx_libc_ifunc2_redirected, s390_libc_ifunc):
	Delete macro definition.
	(s390_libc_ifunc_init): Rename to
	s390_libc_ifunc_expr_stfle_init.
	* sysdeps/s390/bzero: Use
	s390_libc_ifunc_expr_stfle_init instead of
	s390_libc_ifunc_init.

12f0dcb8da S390: Refactor gconv_simple ifunc handling.
The ifunc handling for various __gconv_transform_* functions
which are using IFUNC on s390x are adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Instead those functions are just an alias to the vector variants.

Furthermore the ifunc-macro s390_libc_ifunc_expr is now used instead of
s390_vx_libc_ifunc.

ChangeLog:

	* sysdeps/s390/multiarch/gconv_simple.c (ICONV_VX_IFUNC):
	Define macro dependent on HAVE_S390_MIN_Z13_ZARCH_ASM_SUPPORT.

d2a7436c1c S390: Refactor wmemset ifunc handling.
The ifunc handling for wmemset is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.
Glibc internal calls will use the "newer" ifunc variant.
