commit 34672a317613f76101f37e7dddcf7d793115e2a1

    Fix blocking pthread_join. [BZ #23137]
    On s390 (31bit) if glibc is build with -Os, pthread_join sometimes
    blocks indefinitely. This is e.g. observable with
    testcase intl/tst-gettext6.
    pthread_join is calling lll_wait_tid(tid), which performs the futex-wait
    syscall in a loop as long as tid != 0 (thread is alive).
    On s390 (and build with -Os), tid is loaded from memory before
    comparing against zero and then the tid is loaded a second time
    in order to pass it to the futex-wait-syscall.
    If the thread exits in between, then the futex-wait-syscall is
    called with the value zero and it waits until a futex-wake occurs.
    As the thread is already exited, there won't be a futex-wake.
    In lll_wait_tid, the tid is stored to the local variable __tid,
    which is then used as argument for the futex-wait-syscall.
    But unfortunately the compiler is allowed to reload the value
    from memory.
    With this patch, the tid is loaded with atomic_load_acquire.
    Then the compiler is not allowed to reload the value for __tid from memory.
    	[BZ #23137]
    	* sysdeps/nptl/lowlevellock.h (lll_wait_tid):
    	Use atomic_load_acquire to load __tid.

    manual: Various fixes to the mbstouwcs example, and mbrtowc update
    The example did not work because the null byte was not converted, and
    mbrtowc was called with a zero-length input string.  This results in a
    (size_t) -2 return value, so the function always returns NULL.
    The size computation for the heap allocation of the result was
    incorrect because it did not deal with integer overflow.
    Error checking was missing, and the allocated memory was not freed on
    error paths.  All error returns now set errno.  (Note that there is an
    assumption that free does not clobber errno.)
    The slightly unportable comparision against (size_t) -2 to catch both
    (size_t) -1 and (size_t) -2 return values is gone as well.
    A null wide character needs to be stored in the result explicitly, to
    terminate it.
    The description in the manual is updated to deal with these finer
    points.  The (size_t) -2 behavior (consuming the input bytes) matches
    what is specified in ISO C11.

    Fix signed integer overflow in random_r (bug 17343).
    Bug 17343 reports that stdlib/random_r.c has code with undefined
    behavior because of signed integer overflow on int32_t.  This patch
    changes the code so that the possibly overflowing computations use
    unsigned arithmetic instead.
    Note that the bug report refers to "Most code" in that file.  The
    places changed in this patch are the only ones I found where I think
    such overflow can occur.

    RISC-V: fix struct kernel_sigaction to match the kernel version [BZ #23069]
    The RISC-V kernel doesn't define SA_RESTORER, hence the kernel version
    of struct sigaction doesn't have the sa_restorer field. The default
    kernel_sigaction.h therefore can't be used.
    This patch adds a RISC-V specific version of kernel_sigaction.h to fix
    the issue. This fixes for example the libnih testsuite.
    Note that this patch is not needed in master as the bug has been fixed
    by commit b4a5d26d8835 ("linux: Consolidate sigaction implementation").

    i386: Fix i386 sigaction sa_restorer initialization (BZ#21269)
    This patch fixes the i386 sa_restorer field initialization for sigaction
    syscall for kernel with vDSO.  As described in bug report, i386 Linux
    (and compat on x86_64) interprets SA_RESTORER clear with nonzero
    sa_restorer as a request for stack switching if the SS segment is 'funny'.
    This means that anything that tries to mix glibc's signal handling with
    segmentation (for instance through modify_ldt syscall) is randomly broken
    depending on what values lands in sa_restorer.
    The testcase added  is based on Linux test tools/testing/selftests/x86/ldt_gdt.c,
    more specifically in do_multicpu_tests function.  The main changes are:
      - C11 atomics instead of plain access.
      - Remove x86_64 support which simplifies the syscall handling and fallbacks.
      - Replicate only the test required to trigger the issue.
    Checked on i686-linux-gnu.

    [BZ #22342] Fix netgroup cache keys.
    Unlike other nscd caches, the netgroup cache contains two types of
    records - those for "iterate through a netgroup" (i.e. setnetgrent())
    and those for "is this user in this netgroup" (i.e. innetgr()),
    i.e. full and partial records.  The timeout code assumes these records
    have the same key for the group name, so that the collection of records
    that is "this netgroup" can be expired as a unit.
    However, the keys are not the same, as the in-netgroup key is generated
    by nscd rather than being passed to it from elsewhere, and is generated
    without the trailing NUL.  All other keys have the trailing NUL, and as
    noted in the linked BZ, debug statements confirm that two keys for the
    same netgroup are added to the cache with two different lengths.
    The result of this is that as records in the cache expire, the purge
    code only cleans out one of the two types of entries, resulting in
    stale, possibly incorrect, and possibly inconsistent cache data.
    The patch simply includes the existing NUL in the computation for the
    key length ('key' points to the char after the NUL, and 'group' to the
    first char of the group, so 'key-group' includes the first char to the
    NUL, inclusive).
    	[BZ #22342]

    recently changed it and now VLE configured gas does not support to
    assembler some instruction that might class with VLE (HTM for
    instance).  It also does not help that glibc build hardware lock
    elision support as default (regardless of assembler support).
    Although runtime will not actually enables TLE on SPE hardware
    (since kernel will not advertise it), I see little advantage on
    adding HTM support on SPE built glibc.  SPE uses an incompatible
    ABI which does not allow share the same build with default
    powerpc and HTM code slows down SPE without any benefict.
    This patch fixes it by only building HTM when SPE configuration
    is not used.
    Checked with a powerpc-linux-gnuspe build. I also did some sniff
    tests on a e500 hardware without any issue.

    This is a minor rewording to clarify the behaviour of

    manual: Fix a syntax error.
    The opening parenthesis for function arguments in an @deftypefun need
    to be separated from the function name.  This isn't just a matter of
    the GNU coding style---it causes the "(void" (in this case) to be
    rendered as a part of the function name, causing a visual defect, and
    also results in a warning to the following effect during `make pdf':

    manual: Fix Texinfo warnings about improper node names.
    A number of cross-references to the GCC info manual cause Texinfo
    warnings; e.g.:
      ./creature.texi:11: warning: @xref node name should not contain `.'
    This is due to "gcc.info" being used in the INFO-FILE-NAME (fourth)
    argument.  Changing it to "gcc" removes these warnings.  (Manually

    Fix posix/tst-glob_lstat_compat on alpha [BZ #22818]
    The tst-glob_lstat_compat test needs to run tests on the previous
    version of glob. On alpha, there are three versions of glob, GLIBC_2.0,
    GLIBC_2.1 and GLIBC_2.27, while on other architectures there are only
    the GLIBC_2.0 and GLIBC_2.27 version. Therefore on alpha the previous
    version is GLIBC_2.1 and not GLIBC_2.0.

    [RISC-V] Fix parsing flags in ELF64 files.
    When ldconfig reads Elf64 files to determine the ABI, it used the
    Elf32 type, so read the wrong location, and stored the wrong ABI
    type in the cache, making the cache useless.  This patch uses
    an Elf64 type for Elf64 objects instead.
    Note that pre-patch caches might need to be manually removed and
    regenerated to get the correct ABIs stored.

The GNU C Library

The GNU C Library version 2.28 is now available.

The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.

The GNU C Library is primarily designed to be a portable
and high performance C library.  It follows all relevant
standards including ISO C11 and POSIX.1-2008.  It is also
internationalized and has one of the most complete
internationalization interfaces known.

The GNU C Library webpage is at http://www.gnu.org/software/libc/

Packages for the 2.28 release may be downloaded from:

The mirror list is at http://www.gnu.org/order/ftp.html

NEWS for version 2.28

Major new features:

* The localization data for ISO 14651 is updated to match the 2016
  Edition 4 release of the standard, this matches data provided by
  Unicode 9.0.0.  This update introduces significant improvements to the
  collation of Unicode characters.  This release deviates slightly from
  the standard in that the collation element ordering for lowercase and
  uppercase LATIN script characters is adjusted to ensure that regular
  expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A
  is not matched by [a-z].  With the update many locales have been
  updated to take advantage of the new collation information.  The new
  collation information has increased the size of the compiled locale
  archive or binary locales.

* The GNU C Library can now be compiled with support for Intel CET, AKA
  Intel Control-flow Enforcement Technology.  When the library is built
  with --enable-cet, the resulting glibc is protected with indirect
  branch tracking (IBT) and shadow stack (SHSTK).  CET-enabled glibc is
  compatible with all existing executables and shared libraries.  This
  feature is currently supported on i386, x86_64 and x32 with GCC 8 and
  binutils 2.29 or later.  Note that CET-enabled glibc requires CPUs
  capable of multi-byte NOPs, like x86-64 processors as well as Intel
  Pentium Pro or newer.  NOTE: --enable-cet has been tested for i686,
  x86_64 and x32 on non-CET processors.  --enable-cet has been tested
  for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been
  validated for i686.

* The GNU C Library now has correct support for ABSOLUTE symbols
  (SHN_ABS-relative symbols).  Previously such ABSOLUTE symbols were
  relocated incorrectly or in some cases discarded.  The GNU linker can
  make use of the newer semantics, but it must communicate it to the
  dynamic loader by setting the ELF file's identification (EI_ABIVERSION
  field) to indicate such support is required.

* Unicode 11.0.0 Support: Character encoding, character type info, and
  transliteration tables are all updated to Unicode 11.0.0, using
  generator scripts contributed by Mike FABIAN (Red Hat).

* <math.h> functions that round their results to a narrower type are added
  from TS 18661-1:2014 and TS 18661-3:2015:

  - fadd, faddl, daddl and corresponding fMaddfN, fMaddfNx, fMxaddfN and
    fMxaddfNx functions.

  - fsub, fsubl, dsubl and corresponding fMsubfN, fMsubfNx, fMxsubfN and
    fMxsubfNx functions.

  - fmul, fmull, dmull and corresponding fMmulfN, fMmulfNx, fMxmulfN and
    fMxmulfNx functions.

  - fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and
    fMxdivfNx functions.

* Two grammatical forms of month names are now supported for the following
  languages: Armenian, Asturian, Catalan, Czech, Kashubian, Occitan, Ossetian,
  Scottish Gaelic, Upper Sorbian, and Walloon.  The following languages now
  support two grammatical forms in abbreviated month names: Catalan, Greek,
  and Kashubian.

* Newly added locales: Lower Sorbian (dsb_DE) and Yakut (sah_RU) also
  include the support for two grammatical forms of month names.

* Building and running on GNU/Hurd systems now works without out-of-tree

* The renameat2 function has been added, a variant of the renameat function
  which has a flags argument.  If the flags are zero, the renameat2 function
  acts like renameat.  If the flag is not zero and there is no kernel
  support for renameat2, the function will fail with an errno value of
  EINVAL.  This is different from the existing gnulib function renameatu,
  which performs a plain rename operation in case of a RENAME_NOREPLACE
  flags and a non-existing destination (and therefore has a race condition
  that can clobber the destination inadvertently).

* The statx function has been added, a variant of the fstatat64
  function with an additional flags argument.  If there is no direct
  kernel support for statx, glibc provides basic stat support based on
  the fstatat64 function.

* IDN domain names in getaddrinfo and getnameinfo now use the system libidn2
  library if installed.  libidn2 version 2.0.5 or later is recommended.  If
  libidn2 is not available, internationalized domain names are not encoded
  or decoded even if the AI_IDN or NI_IDN flags are passed to getaddrinfo or
  getnameinfo.  (getaddrinfo calls with non-ASCII names and AI_IDN will fail
  with an encoding error.)  Flags which used to change the IDN encoding and
  deprecated.  They no longer have any effect.

* Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED,
  DT_AUXILIARY, and DT_FILTER has been expanded to support the full
  range of ELF gABI expressions including such constructs as
  '$ORIGIN$ORIGIN' (if valid).  For SUID/GUID applications the rules
  have been further restricted, and where in the past a dynamic string
  token sequence may have been interpreted as a literal string it will
  now cause a load failure.  These load failures were always considered
  unspecified behaviour from the perspective of the dynamic loader, and
  for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED
  results in a load failure now.

* Support for ISO C threads (ISO/IEC 9899:2011) has been added.  The
  implementation includes all the standard functions provided by

  - thrd_current, thrd_equal, thrd_sleep, thrd_yield, thrd_create,
    thrd_detach, thrd_exit, and thrd_join for thread management.

  - mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, and
    mtx_destroy for mutual exclusion.

  - call_once for function call synchronization.

  - cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, and
    cnd_wait for conditional variables.

  - tss_create, tss_delete, tss_get, and tss_set for thread-local storage.

  Application developers must link against libpthread to use ISO C threads.

Deprecated and removed features, and other changes affecting compatibility:

* The nonstandard header files <libio.h> and <_G_config.h> are no longer
  installed.  Software that was using either header should be updated to
  use standard <stdio.h> interfaces instead.

* The stdio functions 'getc' and 'putc' are no longer defined as macros.
  This was never required by the C standard, and the macros just expanded
  to call alternative names for the same functions.  If you hoped getc and
  putc would provide performance improvements over fgetc and fputc, instead
  investigate using (f)getc_unlocked and (f)putc_unlocked, and, if
  necessary, flockfile and funlockfile.

* All stdio functions now treat end-of-file as a sticky condition.  If you
  read from a file until EOF, and then the file is enlarged by another
  process, you must call clearerr or another function with the same effect
  (e.g. fseek, rewind) before you can read the additional data.  This
  corrects a longstanding C99 conformance bug.  It is most likely to affect
  programs that use stdio to read interactive input from a terminal.
  (Bug #1190.)

* The macros 'major', 'minor', and 'makedev' are now only available from
  the header <sys/sysmacros.h>; not from <sys/types.h> or various other
  headers that happen to include <sys/types.h>.  These macros are rarely
  used, not part of POSIX nor XSI, and their names frequently collide with
  user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for
  further explanation.

  <sys/sysmacros.h> is a GNU extension.  Portable programs that require
  these macros should first include <sys/types.h>, and then include
  <sys/sysmacros.h> if __GNU_LIBRARY__ is defined.

* The tilegx*-*-linux-gnu configurations are no longer supported.

* The obsolete function ustat is no longer available to newly linked
  binaries; the headers <ustat.h> and <sys/ustat.h> have been removed.  This
  function has been deprecated in favor of fstatfs and statfs.

* The obsolete function nfsservctl is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and could not usefully be used with the GNU C Library on systems with
  version 3.1 or later of the Linux kernel.

* The obsolete function name llseek is no longer available to newly linked
  binaries.  This function was specific to systems using the Linux kernel
  and was not declared in a header.  Programs should use the lseek64 name
  for this function instead.

  getaddrinfo and getnameinfo functions have been deprecated.  The behavior
  previously selected by them is now always enabled.

  the getaddrinfo and getnameinfo functions have been deprecated.  The STD3
  restriction (rejecting '_' in host names, among other things) has been
  removed, for increased compatibility with non-IDN name resolution.

* The fcntl function now have a Long File Support variant named fcntl64.  It
  is added to fix some Linux Open File Description (OFD) locks usage on non
  LFS mode.  As for others *64 functions, fcntl64 semantics are analogous with
  fcntl and LFS support is handled transparently.  Also for Linux, the OFD
  locks act as a cancellation entrypoint.

* The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt,
  ecb_crypt, and des_setparity are no longer available to newly linked
  binaries, and the headers <rpc/des_crypt.h> and <rpc/rpc_des.h> are no
  longer installed.  These functions encrypted and decrypted data with the
  DES block cipher, which is no longer considered secure.  Software that
  still uses these functions should switch to a modern cryptography library,
  such as libgcrypt.

* Reflecting the removal of the encrypt and setkey functions above, the
  macro _XOPEN_CRYPT is no longer defined.  As a consequence, the crypt
  function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is

* The obsolete function fcrypt is no longer available to newly linked
  binaries.  It was just another name for the standard function crypt,
  and it has not appeared in any header file in many years.

* We have tentative plans to hand off maintenance of the passphrase-hashing
  library, libcrypt, to a separate development project that will, we hope,
  keep up better with new passphrase-hashing algorithms.  We will continue
  to declare 'crypt' in <unistd.h>, and programs that use 'crypt' or
  'crypt_r' should not need to change at all; however, distributions will
  need to install <crypt.h> and libcrypt from a separate project.

  In this release, if the configure option --disable-crypt is used, glibc
  will not install <crypt.h> or libcrypt, making room for the separate
  project's versions of these files.  The plan is to make this the default
  behavior in a future release.

Changes to build and runtime requirements:

  GNU make 4.0 or later is now required to build glibc.
