8260f23616 time/tst-strftime3.c: Disable snprintf warning.
snprintf will only truncate the output if the data its given
is corrupted, but a truncated buffer will not match the
"pristine" data's buffer, which is all we need.  So just
disable the warning via the DIAG macros.

466afec308 ja_JP locale: Add entry for the new Japanese era [BZ #22964]
The Japanese era name will be changed on May 1, 2019.  The Japanese
government made a preliminary announcement on April 1, 2019.

The glibc ja_JP locale must be updated to include the new era name for
strftime's alternative year format support.

Checked on x86_64-linux-gnu.

2f1d61552d time/tst-strftime2.c: Make the file easier to maintain
Express the years as full Gregorian years (e.g., 1988 instead of 88)
and months with natural numbers (1-12 rather than 0-11).

Compare actual dates rather than indexes when selecting the era name.

Declare the local variable era as a string character pointer rather
than an array of chars where the actual string is copied which might
lead to potential buffer overflows in future.

e0e4c321c3 Fix strptime era handling, add more strftime tests [BZ #24394]
Test the transition points between all the currently listed Japanese
era name changes. This includes testing the transition between the
first year date and the second year date. This test will help test
the upcoming Japanese era name change.

Also fixes a fencepost error where the era name isn't properly parsed
by strptime in the last (partial) year of the era.

Example: if an era change happens in Feb 1990, and again in Aug 1995,
that's 5.5 years long, but the 0.5 year wasn't accounted for.

77b6f55347 linux: Assume clock_getres CLOCK_{PROCESS,THREAD}_CPUTIME_ID
The Linux 3.2 clock_getres kernel code (kernel/posix-cpu-timers.c)
issued for clock_getres CLOCK_PROCESS_CPUTIME_ID (process_cpu_clock_getres)
and CLOCK_THREAD_CPUTIME_ID (thread_cpu_clock_getres) call
posix_cpu_clock_getres. And it fails on check_clock only if an invalid
clock is used (not the case) or if we pass an invalid the pid/tid in
29 msb of clock_id (not the case either).

This patch assumes that clock_getres syscall always support
CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID, so there is no need
to fallback to hp-timing support for _SC_MONOTONIC_CLOCK neither to issue
the syscall to certify the clock_id is supported bt the kernel.  This
allows simplify the sysconf support to always use the syscall.

38cc11daa4 nptl: Remove pthread_clock_gettime pthread_clock_settime
This patch removes CLOCK_THREAD_CPUTIME_ID and CLOCK_PROCESS_CPUTIME_ID support
from clock_gettime and clock_settime generic implementation.  For Linux, kernel
already provides supports through the syscall and Hurd HTL lacks
__pthread_clock_gettime and __pthread_clock_settime internal implementation.

As described in clock_gettime man-page [1] on 'Historical note for SMP
system', implementing CLOCK_{THREAD,PROCESS}_CPUTIME_ID with timer registers
is error-prone and susceptible to timing and accurary issues that the libc
can not deal without kernel support.

This allows removes unused code which, however, still incur in some runtime
overhead in thread creation (the struct pthread cpuclock_offset
initialization).

If hurd eventually wants to support them it should either either implement as
a kernel facility (or something related due its architecture) or in system
specific implementation.

5abcddd794 Fix parentheses error in iconvconfig.c and ld-collate.c [BZ #24372]
When -Werror=parentheses is in use, iconvconfig.c builds fail with:

  iconvconfig.c: In function ‘write_output’:
  iconvconfig.c:1084:34: error: suggest parentheses around ‘+’ inside ‘>>’ [-Werror=parentheses]
     hash_size = next_prime (nnames + nnames >> 1);
                             ~~~~~~~^~~~~~~~

This patch adds parentheses to the expression.  Not where suggested by
the compiler warning, but where it produces the expected result, i.e.:
where it has the effect of multiplying nnames by 1.5.

Likewise for elem_size in ld-collate.c.

Tested for powerpc64le.

ac64195ccd iconv, localedef: avoid floating point rounding differences [BZ #24372]
Two cases of "int * 1.4" may result in imprecise results, which
in at least one case resulted in i686 and x86-64 producing
different locale files.  This replaced that floating point multiply
with integer operations.  While the hash table margin is increased
from 40% to 50%, testing shows only 2% increase in overall size
of the locale archive.

477e739b32 Update syscall-names.list for Linux 5.0.
This patch updates sysdeps/unix/sysv/linux/syscall-names.list for
Linux 5.0.  Based on testing with build-many-glibcs.py, the only new
entry needed is for old_getpagesize (a newly added __NR_* name for an
old syscall on ia64).  (Because 5.0 changes how syscall tables are
handled in the kernel, checking diffs wasn't a useful way of looking
for new syscalls in 5.0 as most of the syscall tables were moved to
the new representation without actually adding any syscalls to them.)

Tested with build-many-glibcs.py.

	* sysdeps/unix/sysv/linux/syscall-names.list: Update kernel
	version to 5.0.
	(old_getpagesize): New syscall.

Fixes bug 24216. This patch adds security checks for bk and bk_nextsize pointers
of chunks in large bin when inserting chunk from unsorted bin. It was possible
to write the pointer to victim (newly inserted chunk) to arbitrary memory
locations if bk or bk_nextsize pointers of the next large bin chunk
got corrupted.

a0a0dc8317 Remove obsolete, never-implemented XSI STREAMS declarations
The stub implementations are turned into compat symbols.

Linux actually has two reserved system call numbers (for getpmsg
and putpmsg), but these system calls have never been implemented,
and there are no plans to implement them, so this patch replaces
the wrappers with the generic stubs.

According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>,
the presence of the XSI STREAMS declarations is a minor portability
hazard because they are not actually implemented.

This commit does not change the TIRPC support code in
sunrpc/rpc_svcout.c.  It uses additional XTI functionality and
therefore never worked with glibc.

0c1041ee5b Use Linux 5.0 in build-many-glibcs.py.
This patch makes build-many-glibcs.py use Linux 5.0 in place of 4.20
(now that the test change required to avoid false positives with ulong
in kernel headers has been committed).  This includes adjusting the
logic to compute a tarball URL to handle different major version
numbers (rather than changing the path to hardcode v5.x in place of
v4.x, as someone might still wish to check out a v4.x version).

Tested that build-many-glibcs.py successfully checks out Linux 5.0
sources after this patch.

	version to 5.0.
