    The GNU C Library
    =================
    
    The GNU C Library version 2.31 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.1-2017.  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 2.31 release may be downloaded from:

    NEWS for version 2.31
    =====================
    
    Major new features:
    
    * The GNU C Library now supports a feature test macro _ISOC2X_SOURCE to
      enable features from the draft ISO C2X standard.  Only some features from
      this draft standard are supported by the GNU C Library, and as the draft
      is under active development, the set of features enabled by this macro is
      liable to change.  Features from C2X are also enabled by _GNU_SOURCE, or
      by compiling with "gcc -std=gnu2x".
    
    * The <math.h> functions that round their results to a narrower type now
      have corresponding type-generic macros in <tgmath.h>, as defined in TS
      18661-1:2014 and TS 18661-3:2015 as amended by the resolution of
      Clarification Request 13 to TS 18661-3.
    
    * The function pthread_clockjoin_np has been added, enabling join with a
      terminated thread with a specific clock.  It allows waiting against
      CLOCK_MONOTONIC and CLOCK_REALTIME.  This function is a GNU extension.
    
    * New locale added: mnw_MM (Mon language spoken in Myanmar).
    
    * The DNS stub resolver will optionally send the AD (authenticated data) bit
      in queries if the trust-ad option is set via the options directive in
      /etc/resolv.conf (or if RES_TRUSTAD is set in _res.options).  In this
      mode, the AD bit, as provided by the name server, is available to
      applications which call res_search and related functions.  In the default
      mode, the AD bit is not set in queries, and it is automatically cleared in
      responses, indicating a lack of DNSSEC validation.  (Therefore, the name
      servers and the network path to them are treated as untrusted.)
    
    Deprecated and removed features, and other changes affecting compatibility:
    
    * The totalorder and totalordermag functions, and the corresponding
      functions for other floating-point types, now take pointer arguments to
      avoid signaling NaNs possibly being converted to quiet NaNs in argument
      passing.  This is in accordance with the resolution of Clarification
      Request 25 to TS 18661-1, as applied for C2X.  Existing binaries that pass
      floating-point arguments directly will continue to work.
    
    * The obsolete function stime is no longer available to newly linked
      binaries, and its declaration has been removed from <time.h>.
      Programs that set the system time should use clock_settime instead.
    
    * We plan to remove the obsolete function ftime, and the header <sys/timeb.h>,
      in a future version of glibc.  In this release, the header still exists
      but calling ftime will cause a compiler warning.  All programs should use
      gettimeofday or clock_gettime instead.
    
    * The gettimeofday function no longer reports information about a
      system-wide time zone.  This 4.2-BSD-era feature has been deprecated for
      many years, as it cannot handle the full complexity of the world's
      timezones, but hitherto we have supported it on a best-effort basis.
      Changes required to support 64-bit time_t on 32-bit architectures have
      made this no longer practical.
    
      As of this release, callers of gettimeofday with a non-null 'tzp' argument
      should expect to receive a 'struct timezone' whose tz_minuteswest and
      tz_dsttime fields are zero.  (For efficiency reasons, this does not always
      happen on a few Linux-based ports.  This will be corrected in a future
      release.)
    
      All callers should supply a null pointer for the 'tzp' argument to
      gettimeofday.  For accurate information about the time zone associated
      with the current time, use the localtime function.
    
      gettimeofday itself is obsolescent according to POSIX.  We have no plans
      to remove access to this function, but portable programs should consider
      using clock_gettime instead.
    
    * The settimeofday function can still be used to set a system-wide time
      zone when the operating system supports it.  This is because the Linux
      kernel reused the API, on some architectures, to describe a system-wide
      time-zone-like offset between the software clock maintained by the kernel,
      and the "RTC" clock that keeps time when the system is shut down.
    
      However, to reduce the odds of this offset being set by accident,
      settimeofday can no longer be used to set the time and the offset
      simultaneously.  If both of its two arguments are non-null, the call
      will fail (setting errno to EINVAL).
    
      Callers attempting to set this offset should also be prepared for the call
      to fail and set errno to ENOSYS; this already happens on the Hurd and on
      some Linux architectures.  The Linux kernel maintainers are discussing a
      more principled replacement for the reused API.  After a replacement
      becomes available, we will change settimeofday to fail with ENOSYS on all
      platforms when its 'tzp' argument is not a null pointer.
    
      settimeofday itself is obsolescent according to POSIX.  Programs that set
      the system time should use clock_settime and/or the adjtime family of
      functions instead.  We may cease to make settimeofday available to newly
      linked binaries after there is a replacement for Linux's time-zone-like
      offset API.
    
    * SPARC ISA v7 is no longer supported.  v8 is still supported, but only if
      the optional CAS instruction is implemented (for instance, LEON processors
      are still supported, but SuperSPARC processors are not).
    
      As the oldest 64-bit SPARC ISA is v9, this only affects 32-bit
      configurations.
    
    * If a lazy binding failure happens during dlopen, during the execution of
      an ELF constructor, the process is now terminated.  Previously, the
      dynamic loader would return NULL from dlopen, with the lazy binding error
      captured in a dlerror message.  In general, this is unsafe because
      resetting the stack in an arbitrary function call is not possible.
    
    * For MIPS hard-float ABIs, the GNU C Library will be configured to need an
      executable stack unless explicitly configured at build time to require
      minimum kernel version 4.8 or newer.  This is because executing
      floating-point branches on a non-executable stack on Linux kernels prior to
      4.8 can lead to application crashes for some MIPS configurations. While
      currently PT_GNU_STACK is not widely used on MIPS, future releases of GCC are
      expected to enable non-executable stack by default  with PT_GNU_STACK by
      default and is thus likely to trigger a crash on older kernels.
    
      The GNU C Library can be built with --enable-kernel=4.8.0 in order to keep a
      non-executable stack while dropping support for older kernels.
    
    * System call wrappers for time system calls now use the new time64 system
      calls when available. On 32-bit targets, these wrappers attempt to call
      the new system calls first and fall back to the older 32-bit time system
      calls if they are not present.  This may cause issues in environments
      that cannot handle unsupported system calls gracefully by returning
      -ENOSYS. Seccomp sandboxes are affected by this issue.
    
    Changes to build and runtime requirements:
    
    * It is no longer necessary to have recent Linux kernel headers to build
      working (non-stub) system call wrappers on all architectures except 64-bit
      RISC-V.  64-bit RISC-V requires a minimum kernel headers version of 5.0.
    
    * The ChangeLog file is no longer present in the toplevel directory of the
      source tree.  ChangeLog files are located in the ChangeLog.old directory as
      ChangeLog.N where the highest N has the latest entries.
    
    Security related changes:
    
      CVE-2019-19126: ld.so failed to ignore the LD_PREFER_MAP_32BIT_EXEC
      environment variable during program execution after a security
      transition, allowing local attackers to restrict the possible mapping
      addresses for loaded libraries and thus bypass ASLR for a setuid
      program.  Reported by Marcin Kościelnicki.

    The GNU C Library

    The GNU C Library version 2.30 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.

    NEWS for version 2.30
    =====================
    
    Major new features:
    
    * Unicode 12.1.0 Support: Character encoding, character type info, and
      transliteration tables are all updated to Unicode 12.1.0, using
      generator scripts contributed by Mike FABIAN (Red Hat).
    
    * The dynamic linker accepts the --preload argument to preload shared
      objects, in addition to the LD_PRELOAD environment variable.
    
    * The twalk_r function has been added.  It is similar to the existing
      twalk function, but it passes an additional caller-supplied argument
      to the callback function.
    
    * On Linux, the getdents64, gettid, and tgkill functions have been added.
    
    * Minguo (Republic of China) calendar support has been added as an
      alternative calendar for the following locales: zh_TW, cmn_TW, hak_TW,
      nan_TW, lzh_TW.
    
    * The entry for the new Japanese era has been added for ja_JP locale.
    
    * Memory allocation functions malloc, calloc, realloc, reallocarray, valloc,
      pvalloc, memalign, and posix_memalign fail now with total object size
      larger than PTRDIFF_MAX.  This is to avoid potential undefined behavior with
      pointer subtraction within the allocated object, where results might
      overflow the ptrdiff_t type.
    
    * The dynamic linker no longer refuses to load objects which reference
      versioned symbols whose implementation has moved to a different soname
      since the object has been linked.  The old error message, symbol
      FUNCTION-NAME, version SYMBOL-VERSION not defined in file DSO-NAME with
      link time reference, is gone.
    
    * Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
      pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
      functions.  These behave similarly to their "timed" equivalents, but also
      accept a clockid_t parameter to determine which clock their timeout should
      be measured against.  All functions allow waiting against CLOCK_MONOTONIC
      and CLOCK_REALTIME.  The decision of which clock to be used is made at the
      time of the wait (unlike with pthread_condattr_setclock, which requires
      the clock choice at initialization time).
    
    * On AArch64 the GNU IFUNC resolver call ABI changed: old resolvers still
      work, new resolvers can use a second argument which can be extended in
      the future, currently it contains the AT_HWCAP2 value.
    
    Deprecated and removed features, and other changes affecting compatibility:
    
    * The copy_file_range function fails with ENOSYS if the kernel does not
      support the system call of the same name.  Previously, user space
      emulation was performed, but its behavior did not match the kernel
      behavior, which was deemed too confusing.  Applications which use the
      copy_file_range function can no longer rely on glibc to provide a fallback
      on kernels that do not support the copy_file_range system call, and if
      this function returns ENOSYS, they will need to use their own fallback.
      Support for copy_file_range for most architectures was added in version
      4.5 of the mainline Linux kernel.
    
    * The functions clock_gettime, clock_getres, clock_settime,
      clock_getcpuclockid, clock_nanosleep were removed from the librt library
      for new applications (on architectures which had them).  Instead, the
      definitions in libc will be used automatically, which have been available
      since glibc 2.17.
    
    * The obsolete and never-implemented XSI STREAMS header files <stropts.h>
      and <sys/stropts.h> have been removed.
    
    * Support for the "inet6" option in /etc/resolv.conf and the RES_USE_INET6
      resolver flag (deprecated in glibc 2.25) have been removed.
    
    * The obsolete RES_INSECURE1 and RES_INSECURE2 option flags for the DNS stub
      resolver have been removed from <resolv.h>.
    
    * With --enable-bind-now, installed programs are now linked with the
      BIND_NOW flag.
    
    * Support for the PowerPC SPE ISA extension (powerpc-*-*gnuspe*
      configurations) has been removed, following the deprecation of this
      subarchitecture in version 8 of GCC, and its removal in version 9.
    
    * On 32-bit Arm, support for the port-based I/O emulation and the <sys/io.h>
      header have been removed.
    
    * The Linux-specific <sys/sysctl.h> header and the sysctl function have been
      deprecated and will be removed from a future version of glibc.
      Application should directly access /proc instead.  For obtaining random
      bits, the getentropy function can be used.
    
    Changes to build and runtime requirements:
    
    * GCC 6.2 or later is required to build the GNU C Library.
    
      Older GCC versions and non-GNU compilers are still supported when
      compiling programs that use the GNU C Library.
    
    Security related changes:
    
      CVE-2019-7309: x86-64 memcmp used signed Jcc instructions to check
      size.  For x86-64, memcmp on an object size larger than SSIZE_MAX
      has undefined behavior.  On x32, the size_t argument may be passed
      in the lower 32 bits of the 64-bit RDX register with non-zero upper
      32 bits.  When it happened with the sign bit of RDX register set,
      memcmp gave the wrong result since it treated the size argument as
      zero.  Reported by H.J. Lu.
    
      CVE-2019-9169: Attempted case-insensitive regular-expression match
      via proceed_next_node in posix/regexec.c leads to heap-based buffer
      over-read.  Reported by Hongxu Chen.

    The GNU C Library
    =================
    
    The GNU C Library version 2.29 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 2.29 release may be downloaded from:

    NEWS for version 2.29
    ====================
    
    * The getcpu wrapper function has been added, which returns the currently
      used CPU and NUMA node.  This function is Linux-specific.
    
    * A new convenience target has been added for distribution maintainers
      to build and install all locales as directories with files.  The new
      target is run by issuing the following command in your build tree:
      'make localedata/install-locale-files', with an optional DESTDIR
      to set the install root if you wish to install into a non-default
      configured location.
    
    * Optimized generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf.
    
    * The reallocarray function is now declared under _DEFAULT_SOURCE, not just
      for _GNU_SOURCE, to match BSD environments.
    
    * For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
      indicates that it will abort the transaction prior to entering the kernel
      (PPC_FEATURE2_HTM_NOSC on hwcap2).  On older kernels the transaction is
      suspended, and this caused some undefined side-effects issues by aborting
      transactions manually.  Glibc avoided it by abort transactions manually on
      each syscall, but it lead to performance issues on newer kernels where the
      HTM state is saved and restore lazily (the state being saved even when the
      process actually does not use HTM).
    
    * The functions posix_spawn_file_actions_addchdir_np and
      posix_spawn_file_actions_addfchdir_np have been added, enabling
      posix_spawn and posix_spawnp to run the new process in a different
      directory.  These functions are GNU extensions.  The function
      posix_spawn_file_actions_addchdir_np is similar to the Solaris function
      of the same name.
    
    * The popen and system do not run atfork handlers anymore (BZ#17490).
      Although it is a possible POSIX violation, the POSIX rationale in
      pthread_atfork documentation regarding atfork handlers is to handle
      inconsistent mutex state after a fork call in a multi-threaded process.
      In both popen and system there is no direct access to user-defined mutexes.
    
    * Support for the C-SKY ABIV2 running on Linux has been added.  This port
      requires at least binutils-2.32, gcc-9.0, and linux-4.20.  Two ABIs are
      supported:
        - C-SKY ABIV2 soft-float little-endian
        - C-SKY ABIV2 hard-float little-endian
    
    * strftime's default formatting of a locale's alternative year (%Ey)
      has been changed to zero-pad the year to a minimum of two digits,
      like "%y".  This improves the display of Japanese era years during
      the first nine years of a new era, and is expected to be harmless
      for all other locales (only Japanese locales regularly have
      alternative year numbers less than 10).  Zero-padding can be
      overridden with the '_' or '-' flags (which are GNU extensions).
    
    * As a GNU extension, the '_' and '-' flags can now be applied to
      "%EY" to control how the year number is formatted; they have the
      same effect that they would on "%Ey".
    
    Deprecated and removed features, and other changes affecting compatibility:
    
    * The glibc.tune tunable namespace has been renamed to glibc.cpu and the
      tunable glibc.tune.cpu has been renamed to glibc.cpu.name.
    
    * The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
      in <sys/procfs.h>, has been corrected to match the type actually used by
      the Linux kernel.  This affects the size and layout of that structure on
      MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.
    
    * For the MIPS n32 ABI, the type of the pr_sigpend and pr_sighold members of
      struct elf_prstatus, and the pr_flag member of struct elf_prpsinfo,
      defined in <sys/procfs.h>, has been corrected to match the type actually
      used by the Linux kernel.  This affects the size and layout of those
      structures.
    
    * An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
      meant to scan a string and allocate space for it with malloc, is now
      restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
      defined.  This extension conflicts with C99's use of '%a' to scan a
      hexadecimal floating-point number, which is now available to programs
      compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.
    
      POSIX.1-2008 includes the feature of allocating a buffer for string input
      with malloc, using the modifier letter 'm' instead.  Programs using
      '%as', '%aS', or '%a[...]' with the old GNU meaning should change to
      '%ms', '%mS', or '%m[...]' respectively.  Programs that wish to use the
      C99 '%a' no longer need to avoid _GNU_SOURCE.
    
      GCC's -Wformat warnings can detect most uses of this extension, as long
      as all functions that call vscanf, vfscanf, or vsscanf are annotated with
      __attribute__ ((format (scanf, ...))).
    
    Changes to build and runtime requirements:
    
    * Python 3.4 or later is required to build the GNU C Library.
    
    * On most architectures, GCC 5 or later is required to build the GNU C
      Library.  (On powerpc64le, GCC 6.2 or later is still required, as before.)
    
      Older GCC versions and non-GNU compilers are still supported when
      compiling programs that use the GNU C Library.
    
    Security related changes:
    
      CVE-2018-19591: A file descriptor leak in if_nametoindex can lead to a
      denial of service due to resource exhaustion when processing getaddrinfo
      calls with crafted host names.  Reported by Guido Vranken.
    
      CVE-2019-6488: On x32, the size_t parameter may be passed in the lower
      32 bits of a 64-bit register with with non-zero upper 32 bit.  When it
      happened, accessing the 32-bit size_t value as the full 64-bit register
      in the assembly string/memory functions would cause a buffer overflow.
      Reported by H.J. Lu.
    
      CVE-2016-10739: The getaddrinfo function could successfully parse IPv4
      addresses with arbitrary trailing characters, potentially leading to data
      or command injection issues in applications.

    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
      patches.
    
    * 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
      decoding behavior (AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES,
      NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES) have been
      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
      <threads.h>:
    
      - 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.
    
    * The AI_IDN_ALLOW_UNASSIGNED and NI_IDN_ALLOW_UNASSIGNED flags for the
      getaddrinfo and getnameinfo functions have been deprecated.  The behavior
      previously selected by them is now always enabled.
    
    * The AI_IDN_USE_STD3_ASCII_RULES and NI_IDN_USE_STD3_ASCII_RULES flags for
      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
      enabled.
    
    * 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.
    
    Security related changes:

    The GNU C Library
    =================
    
    The GNU C Library version 2.27 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

    NEWS for version 2.27
    =====================
    
    Major new features:
    
    * The GNU C Library can now be compiled with support for building static
      PIE executables (See --enable-static-pie in INSTALL).  These static PIE
      executables are like static executables but can be loaded at any address
      and provide additional security hardening benefits at the cost of some
      memory and performance.  When the library is built with --enable-static-pie
      the resulting libc.a is usable with GCC 8 and above to create static PIE
      executables using the GCC option '-static-pie'.  This feature is currently
      supported on i386, x86_64 and x32 with binutils 2.29 or later, and on
      aarch64 with binutils 2.30 or later.
    
    * Optimized x86-64 asin, atan2, exp, expf, log, pow, atan, sin, cosf,
      sinf, sincosf and tan with FMA, contributed by Arjan van de Ven and
      H.J. Lu from Intel.
    
    * Optimized x86-64 trunc and truncf for processors with SSE4.1.
    
    * Optimized generic expf, exp2f, logf, log2f, powf, sinf, cosf and sincosf.
    
    * In order to support faster and safer process termination the malloc API
      family of functions will no longer print a failure address and stack
      backtrace after detecting heap corruption.  The goal is to minimize the
      amount of work done after corruption is detected and to avoid potential
      security issues in continued process execution.  Reducing shutdown time
      leads to lower overall process restart latency, so there is benefit both
      from a security and performance perspective.
    
    * The abort function terminates the process immediately, without flushing
      stdio streams.  Previous glibc versions used to flush streams, resulting
      in deadlocks and further data corruption.  This change also affects
      process aborts as the result of assertion failures.
    
    * On platforms where long double has the IEEE binary128 format (aarch64,
      alpha, mips64, riscv, s390 and sparc), the math library now implements
      _Float128 interfaces for that type, as defined by ISO/IEC TS 18661-3:2015.
      These are the same interfaces added in version 2.26 for some platforms where
      this format is supported but is not the format of long double.
    
    * On platforms with support for _Float64x (aarch64, alpha, i386, ia64,
      mips64, powerpc64le, riscv, s390, sparc and x86_64), the math library now
      implements interfaces for that type, as defined by ISO/IEC TS
      18661-3:2015.  These are corresponding interfaces to those supported for
      _Float128.
    
    * The math library now implements interfaces for the _Float32, _Float64 and
      _Float32x types, as defined by ISO/IEC TS 18661-3:2015.  These are
      corresponding interfaces to those supported for _Float128.
    
    * glibc now implements the memfd_create and mlock2 functions on Linux.
    
    * Support for memory protection keys was added.  The <sys/mman.h> header now
      declares the functions pkey_alloc, pkey_free, pkey_mprotect, pkey_set,
      pkey_get.
    
    * The copy_file_range function was added.
    
    * Optimized memcpy, mempcpy, memmove, and memset for sparc M7.
    
    * The ldconfig utility now processes `include' directives using the C/POSIX
      collation ordering.  Previous glibc versions used locale-specific
      ordering, the change might break systems that relied on that.
    
    * Support for two grammatical forms of month names has been added.
      In a call to strftime, the "%B" and "%b" format specifiers will now
      produce the grammatical form required when the month is used as part
      of a complete date.  New "%OB" and "%Ob" specifiers produce the form
      required when the month is named by itself.  For instance, in Greek
      and in many Slavic and Baltic languages, "%B" will produce the month
      in genitive case, and "%OB" will produce the month in nominative case.
    
      In a call to strptime, "%B", "%b", "%h", "%OB", "%Ob", and "%Oh"
      are all valid and will all accept any known form of month
      name---standalone or complete, abbreviated or full.  In a call to
      nl_langinfo, the query constants MON_1..12 and ABMON_1..12 return
      the strings used by "%B" and "%b", respectively.  New query
      constants ALTMON_1..12 and _NL_ABALTMON_1..12 return the strings
      used by "%OB" and "%Ob", respectively.
    
      In a locale definition file, use "alt_mon" and "ab_alt_mon" to
      define the strings for %OB and %Ob, respectively; these have the
      same syntax as "mon" and "abmon".  These arrays are optional; if they
      are not provided then they have the same content as "mon" and "abmon",
      respectively.
    
      These features are provided for locales which define "alt_mon" and/or
      "ab_alt_mon" in their locale source data.  This release includes such
      alternative month name data for the following languages: Belarusian,
      Croatian, Greek, Lithuanian, Polish, Russian, and Ukrainian.
    
      This feature is currently a GNU extension, but it is expected to
      be added to the next revision of POSIX, and it is also already
      available on some BSD-derived operating systems.
    
      This feature will cause existing statically compiled applications
      to fail to load locales and fall back to the builtin C/POSIX locales.
      See notes below for other changes affecting compatibility.
    
    * Support for the RISC-V ISA running on Linux has been added.  This port
      requires at least binutils-2.30, gcc-7.3.0, and linux-4.15; and is supported
      for the following ISA and ABI pairs:
    
        - rv64imac lp64
        - rv64imafdc lp64
        - rv64imafdc lp64d
    
    Deprecated and removed features, and other changes affecting compatibility:
    
    * Statically compiled applications attempting to load locales compiled for the
      GNU C Library version 2.27 will fail and fall back to the builtin C/POSIX
      locale.  The reason for this is that the addition of the new "%OB" and "%Ob",
      support for two grammatical forms of the month names, also extends the locale
      data binary format.  Static applications needing locale support must be
      recompiled to match the runtime and data they are deployed with. In some
      distributions there is an upgrade window where dynamically linked applications
      may use a new library but the old locale data and also fall back to the
      builtin C/POSIX locales; restarting the application process is sufficient to
      fix this.
    
    * Support for statically linked applications which call dlopen is deprecated
      and will be removed in a future version of glibc.  Applications which call
      dlopen need to be linked dynamically instead.
    
    * Support for old programs which use internal stdio data structures and
      functions is deprecated.  This includes programs which use the C++ streams
      provided by libstdc++ in GCC 2.95.  Programs which use the internal
      symbols _IO_adjust_wcolumn, _IO_default_doallocate, _IO_default_finish,
      _IO_default_pbackfail, _IO_default_uflow, _IO_default_xsgetn,
      _IO_default_xsputn, _IO_doallocbuf, _IO_do_write, _IO_file_attach,
      _IO_file_close, _IO_file_close_it, _IO_file_doallocate, _IO_file_fopen,
      _IO_file_init, _IO_file_jumps, _IO_fileno, _IO_file_open,
      _IO_file_overflow, _IO_file_read, _IO_file_seek, _IO_file_seekoff,
      _IO_file_setbuf, _IO_file_stat, _IO_file_sync, _IO_file_underflow,
      _IO_file_write, _IO_file_xsputn, _IO_flockfile, _IO_flush_all,
      _IO_flush_all_linebuffered, _IO_free_backup_area, _IO_free_wbackup_area,
      _IO_init, _IO_init_marker, _IO_init_wmarker, _IO_iter_begin, _IO_iter_end,
      _IO_iter_file, _IO_iter_next, _IO_least_wmarker, _IO_link_in,
      _IO_list_all, _IO_list_lock, _IO_list_resetlock, _IO_list_unlock,
      _IO_marker_delta, _IO_marker_difference, _IO_remove_marker, _IO_seekmark,
      _IO_seekwmark, _IO_str_init_readonly, _IO_str_init_static,
      _IO_str_overflow, _IO_str_pbackfail, _IO_str_seekoff, _IO_str_underflow,
      _IO_switch_to_main_wget_area, _IO_switch_to_wget_mode,
      _IO_unsave_wmarkers, _IO_wdefault_doallocate, _IO_wdefault_finish,
      _IO_wdefault_pbackfail, _IO_wdefault_setbuf, _IO_wdefault_uflow,
      _IO_wdefault_xsgetn, _IO_wdefault_xsputn, _IO_wdoallocbuf, _IO_wdo_write,
      _IO_wfile_jumps, _IO_wfile_overflow, _IO_wfile_sync, _IO_wfile_underflow,
      _IO_wfile_xsputn, _IO_wmarker_delta, or _IO_wsetb may stop working with a
      future version of glibc.  Unlike other symbol removals, these old
      applications will not be supported using compatibility symbols.
    
    * On GNU/Linux, the obsolete Linux constant PTRACE_SEIZE_DEVEL is no longer
      defined by <sys/ptrace.h>.
    
    * libm no longer supports SVID error handling (calling a user-provided
      matherr function on error) or the _LIB_VERSION variable to control error
      handling.  (SVID error handling and the _LIB_VERSION variable still work
      for binaries linked against older versions of the GNU C Library.)  The
      libieee.a library is no longer provided.  math.h no longer defines struct
      exception, or the macros X_TLOSS, DOMAIN, SING, OVERFLOW, UNDERFLOW,
      TLOSS, PLOSS and HUGE.
    
    * The libm functions pow10, pow10f and pow10l are no longer supported for
      new programs.  Programs should use the standard names exp10, exp10f and
      exp10l for these functions instead.
    
    * The mcontext_t type is no longer the same as struct sigcontext.  On
      platforms where it was previously the same, this changes the C++ name
      mangling for interfaces involving this type.
    
    * The add-ons mechanism for building additional packages at the same time as
      glibc has been removed.  The --enable-add-ons configure option is now
      ignored.
    
    * The --without-fp configure option is now ignored.  Whether hardware
      floating-point instructions are used is now configured based on whether
      the compiler used at configure time (without any options implied by a
      --with-cpu= configure option) uses such instructions.
    
    * The res_hnok, res_dnok, res_mailok and res_ownok functions now check that
      the specified string can be parsed as a domain name.
    
    * In the malloc_info output, the <heap> element may contain another <aspace>
      element, "subheaps", which contains the number of sub-heaps.
    
    * The libresolv function p_secstodate is no longer supported for new
      programs.
    
    * The tilepro-*-linux-gnu configuration is no longer supported.
    
    * The nonstandard header files <libio.h> and <_G_config.h> are deprecated
      and will be removed in a future release.  Software that is still using
      either header should be updated to use standard <stdio.h> interfaces
      instead.
    
      libio.h was originally the header for a set of supported GNU extensions,
      but they have not been maintained as such in many years, they are now
      standing in the way of improvements to stdio, and we don't think there are
      any remaining external users.  _G_config.h was never intended for public
      use, but predates the bits convention.
    
    Changes to build and runtime requirements:
    
    * bison version 2.7 or later is required to generate code in the 'intl'
      subdirectory.
    
    Security related changes:
    
      CVE-2009-5064: The ldd script would sometimes run the program under
      examination directly, without preventing code execution through the
      dynamic linker.  (The glibc project disputes that this is a security
      vulnerability; only trusted binaries must be examined using the ldd
      script.)
    
      CVE-2017-15670: The glob function, when invoked with GLOB_TILDE,
      suffered from a one-byte overflow during ~ operator processing (either
      on the stack or the heap, depending on the length of the user name).
      Reported by Tim Rühsen.
    
      CVE-2017-15671: The glob function, when invoked with GLOB_TILDE,
      would sometimes fail to free memory allocated during ~ operator
      processing, leading to a memory leak and, potentially, to a denial
      of service.
    
      CVE-2017-15804: The glob function, when invoked with GLOB_TILDE and
      without GLOB_NOESCAPE, could write past the end of a buffer while
      unescaping user names.  Reported by Tim Rühsen.
    
      CVE-2017-17426: The malloc function, when called with an object size near
      the value SIZE_MAX, would return a pointer to a buffer which is too small,
      instead of NULL.  This was a regression introduced with the new malloc
      thread cache in glibc 2.26.  Reported by Iain Buclaw.
    
      CVE-2017-1000408: Incorrect array size computation in _dl_init_paths leads
      to the allocation of too much memory.  (This is not a security bug per se,
      it is mentioned here only because of the CVE assignment.)  Reported by
      Qualys.
    
      CVE-2017-1000409: Buffer overflow in _dl_init_paths due to miscomputation
      of the number of search path components.  (This is not a security
      vulnerability per se because no trust boundary is crossed if the fix for
      CVE-2017-1000366 has been applied, but it is mentioned here only because
      of the CVE assignment.)  Reported by Qualys.
    
      CVE-2017-16997: Incorrect handling of RPATH or RUNPATH containing $ORIGIN
      for AT_SECURE or SUID binaries could be used to load libraries from the
      current directory.
    
      CVE-2018-1000001: Buffer underflow in realpath function when getcwd function
      succeeds without returning an absolute path due to unexpected behaviour
      of the Linux kernel getcwd syscall.  Reported by halfdog.
    
      CVE-2018-6485: The posix_memalign and memalign functions, when called with
      an object size near the value of SIZE_MAX, would return a pointer to a
      buffer which is too small, instead of NULL.  Reported by Jakub Wilk.
