+/* begin *
+
+ NOTE:
+ ====
+ The patch 'glibc-2.34-c-utf8-locale.patch' should be applyed after 'glibc-2.34-i18n.patch'.
+
+ glibc-2.34-CVE-2021-38604.patch - librt: fix NULL pointer dereference (bug 28213):
+
+ Helper thread frees copied attribute on NOTIFY_REMOVED message
+ received from the OS kernel. Unfortunately, it fails to check whether
+ copied attribute actually exists (data.attr != NULL). This worked
+ earlier because free() checks passed pointer before actually
+ attempting to release corresponding memory. But
+ __pthread_attr_destroy assumes pointer is not NULL.
+
+ So passing NULL pointer to __pthread_attr_destroy will result in
+ segmentation fault. This scenario is possible if
+ notification->sigev_notify_attributes == NULL (which means default
+ thread attributes should be used).
+
+ glibc-2.34-CVE-2021-3998.patch - realpath: Set errno to ENAMETOOLONG for result
+ larger than PATH_MAX [BZ #28770]:
+
+ realpath returns an allocated string when the result exceeds PATH_MAX,
+ which is unexpected when its second argument is not NULL. This results
+ in the second argument (resolved) being uninitialized and also results
+ in a memory leak since the caller expects resolved to be the same as the
+ returned value.
+
+ Return NULL and set errno to ENAMETOOLONG if the result exceeds
+ PATH_MAX. This fixes [BZ #28770], which is CVE-2021-3998.
+
+ glibc-2.34-CVE-2021-3999.patch - getcwd: Set errno to ERANGE for size == 1 (CVE-2021-3999):
+
+ No valid path returned by getcwd would fit into 1 byte, so reject the
+ size early and return NULL with errno set to ERANGE. This change is
+ prompted by CVE-2021-3999, which describes a single byte buffer
+ underflow and overflow when all of the following conditions are met:
+
+ - The buffer size (i.e. the second argument of getcwd) is 1 byte
+ - The current working directory is too long
+ - '/' is also mounted on the current working directory
+
+ Sequence of events:
+
+ - In sysdeps/unix/sysv/linux/getcwd.c, the syscall returns ENAMETOOLONG
+ because the linux kernel checks for name length before it checks
+ buffer size
+
+ - The code falls back to the generic getcwd in sysdeps/posix
+
+ - In the generic func, the buf[0] is set to '\0' on line 250
+
+ - this while loop on line 262 is bypassed:
+
+ while (!(thisdev == rootdev && thisino == rootino))
+
+ since the rootfs (/) is bind mounted onto the directory and the flow
+ goes on to line 449, where it puts a '/' in the byte before the
+ buffer.
+
+ - Finally on line 458, it moves 2 bytes (the underflowed byte and the
+ '\0') to the buf[0] and buf[1], resulting in a 1 byte buffer overflow.
+
+ - buf is returned on line 469 and errno is not set.
+
+ This resolves BZ #28769.
+
+ * end */

+
+Please send GNU C library bug reports via <https://sourceware.org/bugzilla/>
+using `glibc' in the "product" field.
+
+Version 2.34
+
+Major new features:
+
+* In order to support smoother in-place-upgrades and to simplify
+ the implementation of the runtime all functionality formerly
+ implemented in the libraries libpthread, libdl, libutil, libanl has
+ been integrated into libc. New applications do not need to link with
+ -lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility,
+ empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are
+ provided, so that the linker options keep working. Applications which
+ have been linked against glibc 2.33 or earlier continue to load the
+ corresponding shared objects (which are now empty). The integration
+ of those libraries into libc means that additional symbols become
+ available by default. This can cause applications that contain weak
+ references to take unexpected code paths that would only have been
+ used in previous glibc versions when e.g. preloading libpthread.so.0,
+ potentially exposing application bugs.
+
+* When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined,
+ PTHREAD_STACK_MIN is no longer constant and is redefined to
+ sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register
+ sets for modern architectural features like Arm SVE.
+
+* Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE
+ or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer
+ constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ)
+ and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports
+ dynamic sized register sets for modern architectural features like
+ Arm SVE.
+
+* The dynamic linker implements the --list-diagnostics option, printing
+ a dump of information related to IFUNC resolver operation and
+ glibc-hwcaps subdirectory selection.
+
+* On Linux, the function execveat has been added. It operates similar to
+ execve and it is is already used to implement fexecve without requiring
+ /proc to be mounted. However, different than fexecve, if the syscall is not
+ supported by the kernel an error is returned instead of trying a fallback.
+
+* The ISO C2X function timespec_getres has been added.
+
+* The feature test macro __STDC_WANT_IEC_60559_EXT__, from draft ISO
+ C2X, is supported to enable declarations of functions defined in Annex F
+ of C2X. Those declarations are also enabled when
+ __STDC_WANT_IEC_60559_BFP_EXT__, as specified in TS 18661-1, is
+ defined, and when _GNU_SOURCE is defined.
+
+* On powerpc64*, glibc can now be compiled without scv support using the
+ --disable-scv configure option.
+
+* Add support for 64-bit time_t on configurations like x86 where time_t
+ is traditionally 32-bit. Although time_t still defaults to 32-bit on
+ these configurations, this default may change in future versions.
+ This is enabled with the _TIME_BITS preprocessor macro set to 64 and is
+ only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is
+ only enabled for Linux and the full support requires a minimum kernel
+ version of 5.1.
+
+* The main gconv-modules file in glibc now contains only a small set of
+ essential converter modules and the rest have been moved into a supplementary
+ configuration file gconv-modules-extra.conf in the gconv-modules.d directory
+ in the same GCONV_PATH. Similarly, external converter modules directories
+ may have supplementary configuration files in a gconv-modules.d directory
+ with names ending with .conf to logically classify the converter modules in
+ that directory.
+
+* On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used
+ to configure the size of the thread stack cache.
+
+* The function _Fork has been added as an async-signal-safe fork replacement
+ since Austin Group issue 62 droped the async-signal-safe requirement for
+ fork (and it will be included in the future POSIX standard). The new _Fork
+ function does not run any atfork function neither resets any internal state
+ or lock (such as the malloc one), and only sets up a minimal state required
+ to call async-signal-safe functions (such as raise or execve). This function
+ is currently a GNU extension.
+
+* On Linux, the close_range function has been added. It allows efficiently
+ closing a range of file descriptors on recent kernels (version 5.9).
+
+* The function closefrom has been added. It closes all file descriptors
+ greater than or equal to a given integer. This function is a GNU extension,
+ although it is also present in other systems.
+
+* The posix_spawn_file_actions_addclosefrom_np function has been added,
+ enabling posix_spawn and posix_spawnp to close all file descriptors greater
+ than or equal to a given integer. This function is a GNU extension,
+ although Solaris also provides a similar function.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The function pthread_mutex_consistent_np has been deprecated; programs
+ should use the equivalent standard function pthread_mutex_consistent
+ instead.
+
+* The function pthread_mutexattr_getrobust_np has been deprecated;
+ programs should use the equivalent standard function
+ pthread_mutexattr_getrobust instead.
+
+* The function pthread_mutexattr_setrobust_np has been deprecated;
+ programs should use the equivalent standard function
+ pthread_mutexattr_setrobust instead.
+
+* The function pthread_yield has been deprecated; programs should use
+ the equivalent standard function sched_yield instead.
+
+* The function inet_neta declared in <arpa/inet.h> has been deprecated.
+
+* Various rarely-used functions declared in <resolv.h> and
+ <arpa/nameser.h> have been deprecated. Applications are encouraged to
+ use dedicated DNS processing libraries if applicable. For <resolv.h>,
+ this affects the functions dn_count_labels, fp_nquery, fp_query,
+ fp_resstat, hostalias, loc_aton, loc_ntoa, p_cdname, p_cdnname,
+ p_class, p_fqname, p_fqnname, p_option, p_query, p_rcode, p_time,
+ p_type, putlong, putshort, res_hostalias, res_isourserver,
+ res_nameinquery, res_queriesmatch, res_randomid, sym_ntop, sym_ntos,
+ sym_ston. For <arpa/nameser.h>, the functions ns_datetosecs,
+ ns_format_ttl, ns_makecanon, ns_parse_ttl, ns_samedomain, ns_samename,
+ ns_sprintrr, ns_sprintrrf, ns_subdomain have been deprecated.
+
+* Various symbols previously defined in libresolv have been moved to libc
+ in order to prepare for libresolv moving entirely into libc (see earlier
+ entry for merging libraries into libc). The symbols __dn_comp,
+ __dn_expand, __dn_skipname, __res_dnok, __res_hnok, __res_mailok,
+ __res_mkquery, __res_nmkquery, __res_nquery, __res_nquerydomain,
+ __res_nsearch, __res_nsend, __res_ownok, __res_query, __res_querydomain,
+ __res_search, __res_send formerly in libresolv have been renamed and no
+ longer have a __ prefix. They are now available in libc.
+
+* The pthread cancellation handler is now installed with SA_RESTART and
+ pthread_cancel will always send the internal SIGCANCEL on a cancellation
+ request. It should not be visible to applications since the cancellation
+ handler should either act upon cancellation (if asynchronous cancellation
+ is enabled) or ignore the cancellation internal signal. However there are
+ buggy kernel interfaces (for instance some CIFS versions) that could still
+ see a spurious EINTR error when cancellation interrupts a blocking syscall.
+
+* Previously, glibc installed its various shared objects under versioned
+ file names such as libc-2.33.so. The ABI sonames (e.g., libc.so.6)
+ were provided as symbolic links. Starting with glibc 2.34, the shared
+ objects are installed under their ABI sonames directly, without
+ symbolic links. This increases compatibility with distribution
+ package managers that delete removed files late during the package
+ upgrade or downgrade process.
+
+* The symbols mallwatch and tr_break are now deprecated and no longer used in
+ mtrace. Similar functionality can be achieved by using conditional
+ breakpoints within mtrace functions from within gdb.
+
+* The __morecore and __after_morecore_hook malloc hooks and the default
+ implementation __default_morecore have been removed from the API. Existing
+ applications will continue to link against these symbols but the interfaces
+ no longer have any effect on malloc.
+
+* Debugging features in malloc such as the MALLOC_CHECK_ environment variable
+ (or the glibc.malloc.check tunable), mtrace() and mcheck() have now been
+ disabled by default in the main C library. Users looking to use these
+ features now need to preload a new debugging DSO libc_malloc_debug.so to get
+ this functionality back.
+
+* The deprecated functions malloc_get_state and malloc_set_state have been
+ moved from the core C library into libc_malloc_debug.so. Legacy applications
+ that still use these functions will now need to preload libc_malloc_debug.so
+ in their environment using the LD_PRELOAD environment variable.
+
+* The deprecated memory allocation hooks __malloc_hook, __realloc_hook,
+ __memalign_hook and __free_hook are now removed from the API. Compatibility
+ symbols are present to support legacy programs but new applications can no
+ longer link to these symbols. These hooks no longer have any effect on glibc
+ functionality. The malloc debugging DSO libc_malloc_debug.so currently
+ supports hooks and can be preloaded to get this functionality back for older
+ programs. However this is a transitional measure and may be removed in a
+ future release of the GNU C Library. Users may port away from these hooks by
+ writing and preloading their own malloc interposition library.
+
+Changes to build and runtime requirements:
+
+* On Linux, the shm_open, sem_open, and related functions now expect the
+ file shared memory file system to be mounted at /dev/shm. These functions
+ no longer search among the system's mount points for a suitable
+ replacement if /dev/shm is not available.
+
+Security related changes:
+
+ CVE-2021-27645: The nameserver caching daemon (nscd), when processing
+ a request for netgroup lookup, may crash due to a double-free,
+ potentially resulting in degraded service or Denial of Service on the
+ local system. Reported by Chris Schanzle.
+
+ CVE-2021-33574: The mq_notify function has a potential use-after-free
+ issue when using a notification type of SIGEV_THREAD and a thread
+ attribute with a non-default affinity mask.
+
+ CVE-2021-35942: The wordexp function may overflow the positional
+ parameter number when processing the expansion resulting in a crash.
+ Reported by Philippe Antoine.
+
+ CVE-2021-3998: Passing a path longer than PATH_MAX to the realpath
+ function could result in a memory leak and potential access of
+ uninitialized memory. Reported by Qualys.
+
+ CVE-2021-3999: Passing a buffer of size exactly 1 byte to the getcwd
+ function may result in an off-by-one buffer underflow and overflow
+ when the current working directory is longer than PATH_MAX and also
+ corresponds to the / directory through an unprivileged mount
+ namespace. Reported by Qualys.

+
+Version 2.33
+
+Major new features:
+
+* The dynamic linker accepts the --list-tunables argument which prints
+ all the supported tunables. This option is disable if glibc is
+ configured with tunables disabled (--enable-tunables=no).
+
+* The dynamic linker accepts the --argv0 argument and provides opportunity
+ to change argv[0] string.
+
+* The dynamic linker loads optimized implementations of shared objects
+ from subdirectories under the glibc-hwcaps directory on the library
+ search path if the system's capabilities meet the requirements for
+ that subdirectory. Initially supported subdirectories include
+ "power9" and "power10" for the powerpc64le-linux-gnu architecture,
+ "z13", "z14", "z15" for s390x-linux-gnu, and "x86-64-v2", "x86-64-v3",
+ "x86-64-v4" for x86_64-linux-gnu. In the x86_64-linux-gnu case, the
+ subdirectory names correspond to the vendor-independent x86-64
+ microarchitecture levels defined in the x86-64 psABI supplement.
+
+* The new --help option of the dynamic linker provides usage and
+ information and library search path diagnostics.
+
+* The mallinfo2 function is added to report statistics as per mallinfo,
+ but with larger field widths to accurately report values that are
+ larger than fit in an integer.
+
+* Add <sys/platform/x86.h> to provide query macros for x86 CPU features.
+
+* Support for the RISC-V ISA running on Linux has been expanded to run on
+ 32-bit hardware. This is supported for the following ISA and ABI pairs:
+
+ - rv32imac ilp32
+ - rv32imafdc ilp32
+ - rv32imafdc ilp32d
+
+ The 32-bit RISC-V port requires at least Linux 5.4, GCC 7.1 and binutils
+ 2.28.
+
+* A new fortification level _FORTIFY_SOURCE=3 is available. At this level,
+ glibc may use additional checks that may have an additional performance
+ overhead. At present these checks are available only on LLVM 9 and later.
+ The latest GCC available at this time (10.2) does not support this level of
+ fortification.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The mallinfo function is marked deprecated. Callers should call
+ mallinfo2 instead.
+
+* When dlopen is used in statically linked programs, alternative library
+ implementations from HWCAP subdirectories are no longer loaded.
+ Instead, the default implementation is used.
+
+* The deprecated <sys/vtimes.h> header and the function vtimes have been
+ removed. To support old binaries, the vtimes function continues to exist
+ as a compatibility symbol. Applications should use the getrlimit or
+ prlimit.
+
+* Following a change in the tzdata 2018a release upstream, the zdump
+ program is now installed in the /usr/bin subdirectory. Previously,
+ the /usr/sbin subdirectory was used.
+
+* On s390(x), the type float_t is now derived from the macro
+ __FLT_EVAL_METHOD__ that is defined by the compiler, instead of being
+ hardcoded to double. This does not affect the ABI of any libraries
+ that are part of the GNU C Library, but may affect the ABI of other
+ libraries that use this type in their interfaces. The new definition
+ improves consistency with compiler behavior in many scenarios.
+
+* A future version of glibc will stop loading shared objects from the
+ "tls" subdirectories on the library search path, the subdirectory that
+ corresponds to the AT_PLATFORM system name, and also stop employing
+ the legacy AT_HWCAP search mechanism. Applications should switch to
+ the new glibc-hwcaps mechanism instead; if they do not do that, only
+ the baseline version (directly from the search path directory) will be
+ loaded.
+
+Changes to build and runtime requirements:
+
+* On Linux, the system administrator needs to configure /dev/pts with
+ the intended access modes for pseudo-terminals. glibc no longer
+ attemps to adjust permissions of terminal devices. The previous glibc
+ defaults ("tty" group, user read/write and group write) already
+ corresponded to what most systems used, so that grantpt did not
+ perform any adjustments.
+
+* On Linux, the posix_openpt and getpt functions no longer attempt to
+ use legacy (BSD) pseudo-terminals and assume that if /dev/ptmx exists
+ (and pseudo-terminals are supported), a devpts file system is mounted
+ on /dev/pts. Current systems already meet these requirements.
+
+* s390x requires GCC 7.1 or newer. See gcc Bug 98269.
+
+Security related changes:
+
+ CVE-2021-3326: An assertion failure during conversion from the
+ ISO-20220-JP-3 character set using the iconv function has been fixed.
+ This assertion was triggered by certain valid inputs in which the
+ converted output contains a combined sequence of two wide characters
+ crossing a buffer boundary. Reported by Tavis Ormandy.
+
+ CVE-2020-27618: An infinite loop has been fixed in the iconv program when
+ invoked with input containing redundant shift sequences in the IBM1364,

+Version 2.32
+
+Major new features:
+
+* Unicode 13.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 13.0.0, using
+ generator scripts contributed by Mike FABIAN (Red Hat).
+
+* New locale added: ckb_IQ (Kurdish/Sorani spoken in Iraq)
+
+* Support for Synopsys ARC HS cores (ARCv2 ISA) running Linux has been
+ added. This port requires at least binutils-2.32, gcc-8.3 and Linux-5.1.
+ Three ABIs are supported:
+
+ - arc-linux-gnu
+ - arc-linux-gnuhf
+ - arceb-linux-gnu
+
+ The arc* ABIs are little-endian while arceb is big-endian. All ABIs use
+ 64-bit time (y2038 safe) and 64-bit file offsets (LFS default).
+
+* The GNU C Library now loads audit modules listed in the DT_AUDIT and
+ DT_DEPAUDIT dynamic section entries of the main executable.
+
+* powerpc64le supports IEEE128 long double libm/libc redirects when
+ using -mabi=ieeelongdouble to compile C code on supported GCC
+ toolchains. It is recommended to use GCC 8 or newer when testing
+ this option.
+
+* To help detect buffer overflows and other out-of-bounds accesses
+ several APIs have been annotated with GCC 'access' attribute. This
+ should help GCC 10 issue better warnings.
+
+* On Linux, functions pthread_attr_setsigmask_np and
+ pthread_attr_getsigmask_np have been added. They allow applications
+ to specify the signal mask of a thread created with pthread_create.
+
+* The GNU C Library now provides the header file <sys/single_threaded.h>
+ which declares the variable __libc_single_threaded. Applications are
+ encouraged to use this variable for single-thread optimizations,
+ instead of weak references to symbols historically defined in
+ libpthread.
+
+* The functions sigabbrev_np and sigdescr_np have been added. The
+ sigabbrev_np function returns the abbreviated signal name (e.g. "HUP" for
+ SIGHUP) while sigdescr_np returns a string describing the signal number
+ (e.g "Hangup" for SIGHUP). Different than strsignal, sigdescr_np does not
+ attempt to translate the return description, both functions return
+ NULL for an invalid signal number.
+
+ They should be used instead of sys_siglist or sys_sigabbrev and they
+ are both thread and async-signal safe. These functions are GNU extensions.
+
+* The functions strerrorname_np and strerrordesc_np have been added. The
+ strerroname_np function returns error number name (e.g. "EINVAL" for EINVAL)
+ while strerrordesc_np returns a string describing the error number
+ (e.g "Invalid argument" for EINVAL). Different than strerror,
+ strerrordesc_np does not attempt to translate the return description, both
+ functions return NULL for an invalid error number.
+
+ They should be used instead of sys_errlist and sys_nerr, both are
+ thread and async-signal safe. These functions are GNU extensions.
+
+* AArch64 now supports standard branch protection security hardening
+ in glibc when it is built with a GCC that is configured with
+ --enable-standard-branch-protection (or if -mbranch-protection=standard
+ flag is passed when building both GCC target libraries and glibc,
+ in either case a custom GCC is needed). This includes branch target
+ identification (BTI) and pointer authentication for return addresses
+ (PAC-RET). They require armv8.5-a and armv8.3-a architecture
+ extensions respectively for the protection to be effective,
+ otherwise the used instructions are nops. User code can use PAC-RET
+ without libc support, but BTI requires a libc that is built with BTI
+ support, otherwise runtime objects linked into user code will not be
+ BTI compatible.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* Remove configure option --enable-obsolete-rpc. Sun RPC is removed
+ from glibc. This includes the rpcgen program, librpcsvc, and the Sun
+ RPC header files. Backward compatibility for old programs is kept
+ only for architectures and ABIs that have been added in or before
+ glibc 2.31. New programs need to use TI-RPC
+ <http://git.linux-nfs.org/?p=steved/libtirpc.git;a=summary> and
+ rpcsvc-proto <https://github.com/thkukuk/rpcsvc-proto>.
+
+* Remove configure option --enable-obsolete-nsl. libnsl is only built
+ as shared library for backward compatibility and the NSS modules "nis"
+ and "nisplus" are not built at all and libnsl's headers aren't
+ installed. This compatibility is kept only for architectures and ABIs
+ that have been added in or before version 2.28. Replacement
+ implementations based on TI-RPC, which additionally support IPv6, are
+ available from <https://github.com/thkukuk/>. This change does not
+ affect the "compat" NSS module, which does not depend on libnsl
+ since 2.27 and thus can be used without NIS.
+
+* The deprecated <sys/sysctl.h> header and the sysctl function have been
+ removed. To support old binaries, the sysctl function continues to
+ exist as a compatibility symbol (on those architectures which had it),
+ but always fails with ENOSYS. This reflects the removal of the system
+ call from all architectures, starting with Linux 5.5.
+
+* The sstk function is no longer available to newly linked binaries.
+ Its implementation always returned with a failure, and the function
+ was not declared in any header file.
+
+* The legacy signal handling functions siginterrupt, sigpause, sighold,
+ sigrelse, sigignore and sigset, and the sigmask macro have been
+ deprecated. Applications should use the sigsuspend, sigprocmask and
+ sigaction functions instead.
+
+* ldconfig now defaults to the new format for ld.so.cache. glibc has
+ already supported this format for almost 20 years.
+
+* The deprecated arrays sys_siglist, _sys_siglist, and sys_sigabbrev
+ are no longer available to newly linked binaries, and their declarations
+ have been removed from <string.h>. They are exported solely as
+ compatibility symbols to support old binaries. All programs should use
+ strsignal instead.
+
+* The deprecated symbols sys_errlist, _sys_errlist, sys_nerr, and _sys_nerr
+ are no longer available to newly linked binaries, and their declarations
+ have been removed from <stdio.h>. They are exported solely as
+ compatibility symbols to support old binaries. All programs should use
+ strerror or strerror_r instead.
+
+* Both strerror and strerror_l now share the same internal buffer in the
+ calling thread, meaning that the returned string pointer may be invalided
+ or contents might be overwritten on subsequent calls in the same thread or
+ if the thread is terminated. It makes strerror MT-safe.
+
+* Using weak references to libpthread functions such as pthread_create
+ or pthread_key_create to detect the singled-threaded nature of a
+ program is an obsolescent feature. Future versions of glibc will
+ define pthread_create within libc.so.6 itself, so such checks will
+ always flag the program as multi-threaded. Applications should check
+ the __libc_single_threaded variable declared in
+ <sys/single_threaded.h> instead.
+
+* The "files" NSS module no longer supports the "key" database (used for
+ secure RPC). The contents of the /etc/publickey file will be ignored,
+ regardless of the settings in /etc/nsswitch.conf. (This method of
+ storing RPC keys only supported the obsolete and insecure AUTH_DES
+ flavor of secure RPC.)
+
+* The __morecore and __after_morecore_hook malloc hooks and the default
+ implementation __default_morecore have been deprecated. Applications
+ should use malloc interposition to change malloc behavior, and mmap to
+ allocate anonymous memory. A future version of glibc may require that
+ applications which use the malloc hooks must preload a special shared
+ object, to enable the hooks.
+
+* The hesiod NSS module has been deprecated and will be removed in a
+ future version of glibc. System administrators are encouraged to
+ switch to other approaches for networked account databases, such as
+ LDAP.
+
+Changes to build and runtime requirements:
+
+* powerpc64le requires GCC 7.4 or newer. This is required for supporting
+ long double redirects.

+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-2020-1751: A defect in the PowerPC backtrace function could cause an
+ out-of-bounds write when executed in a signal frame context.
+
+ 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.

+
+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.

+
+Version 2.29
+
+Major new features:
+
+* 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.

+
+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.

+
+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.
+
+ CVE-2018-6551: The malloc function, 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.

+Version 2.26
+
+Major new features:
+
+* A per-thread cache has been added to malloc. Access to the cache requires
+ no locks and therefore significantly accelerates the fast path to allocate
+ and free small amounts of memory. Refilling an empty cache requires locking
+ the underlying arena. Performance measurements show significant gains in a
+ wide variety of user workloads. Workloads were captured using a special
+ instrumented malloc and analyzed with a malloc simulator. Contributed by
+ DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
+
+* Unicode 10.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 10.0.0, using
+ generator scripts contributed by Mike FABIAN (Red Hat).
+ These updates cause user visible changes, especially the changes in
+ wcwidth for many emoji characters cause problems when emoji sequences
+ are rendered with pango, see for example:
+ https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
+
+* Collation of Hungarian has been overhauled and is now consistent with "The
+ Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
+ Egmont Koblinger.
+
+* Improvements to the DNS stub resolver, contributed by Florian Weimer:
+
+ - The GNU C Library will now detect when /etc/resolv.conf has been
+ modified and reload the changed configuration. The new resolver option
+ “no-reload” (RES_NORELOAD) disables this behavior.
+
+ - The GNU C Library now supports an arbitrary number of search domains
+ (configured using the “search” directive in /etc/resolv.conf);
+ previously, there was a hard limit of six domains. For backward
+ compatibility, applications that directly modify the ‘_res’ global
+ object are still limited to six search domains.
+
+ - When the “rotate” (RES_ROTATE) resolver option is active, the GNU C
+ Library will now randomly pick a name server from the configuration as a
+ starting point. (Previously, the second name server was always used.)
+
+* The tunables feature is now enabled by default. This allows users to tweak
+ behavior of the GNU C Library using the GLIBC_TUNABLES environment variable.
+
+* New function reallocarray, which resizes an allocated block (like realloc)
+ to the product of two sizes, with a guaranteed clean failure upon integer
+ overflow in the multiplication. Originally from OpenBSD, contributed by
+ Dennis Wölfing and Rüdiger Sonderfeld.
+
+* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
+ These are extended versions of preadv and pwritev, respectively, taking an
+ additional flags argument. The set of supported flags depends on the
+ running kernel; full support currently requires kernel 4.7 or later.
+
+* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
+ create a new session ID for the spawned process. This feature is
+ scheduled to be added to the next major revision of POSIX; for the time
+ being, it is available under _GNU_SOURCE.
+
+* errno.h is now safe to use from C-preprocessed assembly language on all
+ supported operating systems. In this context, it will only define the
+ Exxxx constants, as preprocessor macros expanding to integer literals.
+
+* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
+ 128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
+ 754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
+ Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
+
+ To compile programs that use this feature, the compiler must support
+ 128-bit floating point with the type name _Float128 (as defined by TS
+ 18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
+ C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
+ must be defined to make the new interfaces visible.
+
+ The new functions and macros correspond to those present for other
+ floating-point types (except for a few obsolescent interfaces not
+ supported for the new type), with F128 or f128 suffixes; for example,
+ strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
+ printf or scanf formats for the new type; the strfromf128 and strtof128
+ interfaces should be used instead.
+
+Deprecated and removed features, and other changes affecting compatibility:
+
+* The synchronization that pthread_spin_unlock performs has been changed to
+ now be equivalent to a C11 atomic store with release memory order to the
+ spin lock's memory location. Previously, several (but not all)
+ architectures used stronger synchronization (e.g., containing what is
+ often called a full barrier). This change can improve performance, but
+ may affect odd fringe uses of spin locks that depend on the previous
+ behavior (e.g., using spin locks as atomic variables to try to implement
+ Dekker's mutual exclusion algorithm).
+
+* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
+ removed.
+
+* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
+ will only be built and installed when the GNU C Library is configured with
+ --enable-obsolete-rpc. This allows alternative RPC implementations, such
+ as TIRPC or rpcsvc-proto, to be used.
+
+* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
+ libnss_compat, are deprecated, and will not be built or installed by
+ default.
+
+ The NIS(+) support library, libnsl, is also deprecated. By default, a
+ compatibility shared library will be built and installed, but not headers
+ or development libraries. Only a few NIS-related programs require this
+ library. (In particular, the GNU C Library has never required programs
+ that use 'gethostbyname' to be linked with libnsl.)
+
+ Replacement implementations based on TIRPC, which additionally support
+ IPv6, are available from <https://github.com/thkukuk/>. The configure
+ option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
+ name service modules, to be built and installed.
+
+* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
+ support is enabled, the configured recursive resolver must support EDNS.
+ (Responding to EDNS-enabled queries with responses which are not
+ EDNS-enabled is fine, but FORMERR responses are not.)
+
+* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
+ servers have not supported this opcode for a long time.
+
+* The _res_opcodes variable has been removed from libresolv. It had been
+ exported by accident.
+
+* <string.h> no longer includes inline versions of any string functions,
+ as this kind of optimization is better done by the compiler. The macros
+ __USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
+
+* The nonstandard header <xlocale.h> has been removed. Most programs should
+ use <locale.h> instead. If you have a specific need for the definition of
+ locale_t with no other declarations, please contact
+ libc-alpha@sourceware.org and explain.
+
+* The obsolete header <sys/ultrasound.h> has been removed.
+
+* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
+
+* The obsolete function cfree has been removed. Applications should use
+ free instead.
+
+* The stack_t type no longer has the name struct sigaltstack. This changes
+ the C++ name mangling for interfaces involving this type.
+
+* The ucontext_t type no longer has the name struct ucontext. This changes
+ the C++ name mangling for interfaces involving this type.
+
+* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
+ the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
+ longer has the name struct mcontext. On SPARC GNU/Linux, the struct
+ mc_fq, struct rwindow, struct fpq and struct fq types are no longer
+ defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
+ mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
+ fpregset_t type no longer has the name struct fpu. This changes the C++
+ name mangling for interfaces involving those types.
+
+* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
+ synced with the kernel:
+
+ - PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
+ are not supported on this architecture and have been removed.
+
+ - PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
+ PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
+ PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
+
+ Programs that assume the GET/SETREGS ptrace requests are universally
+ available will now fail to build, instead of malfunctioning at runtime.
+
+Changes to build and runtime requirements:
+
+* Linux kernel 3.2 or later is required at runtime, on all architectures
+ supported by that kernel. (This is a change from version 2.25 only for
+ x86-32 and x86-64.)
+
+* GNU Binutils 2.25 or later is now required to build the GNU C Library.
+
+* On most architectures, GCC 4.9 or later is required to build the GNU C
+ Library. On powerpc64le, GCC 6.2 or later is required.
+
+ Older GCC versions and non-GNU compilers are still supported when
+ compiling programs that use the GNU C Library. (We do not know exactly
+ how old, and some GNU extensions to C may be _de facto_ required. If you
+ are interested in helping us make this statement less vague, please
+ contact libc-alpha@sourceware.org.)
+
+Security related changes:
+
+* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
+ to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
+
+* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
+ mode to guard against local privilege escalation attacks (CVE-2017-1000366).
+
+* Avoid printing a backtrace from the __stack_chk_fail function since it is
+ called on a corrupt stack and a backtrace is unreliable on a corrupt stack
+ (CVE-2010-3192).
+
+* A use-after-free vulnerability in clntudp_call in the Sun RPC system has been
+ fixed (CVE-2017-12133).

+Version 2.25
+
+* The feature test macro __STDC_WANT_LIB_EXT2__, from ISO/IEC TR
+ 24731-2:2010, is supported to enable declarations of functions from that
+ TR. Note that not all functions from that TR are supported by the GNU C
+ Library.
+
+* The feature test macro __STDC_WANT_IEC_60559_BFP_EXT__, from ISO/IEC TS
+ 18661-1:2014, is supported to enable declarations of functions and macros
+ from that TS. Note that not all features from that TS are supported by
+ the GNU C Library.
+
+* The feature test macro __STDC_WANT_IEC_60559_FUNCS_EXT__, from ISO/IEC TS
+ 18661-4:2015, is supported to enable declarations of functions and macros
+ from that TS. Note that most features from that TS are not supported by
+ the GNU C Library.
+
+* The nonstandard feature selection macros _REENTRANT and _THREAD_SAFE are
+ now treated as compatibility synonyms for _POSIX_C_SOURCE=199506L.
+ Since the GNU C Library defaults to a much newer revision of POSIX, this
+ will only affect programs that specifically request an old conformance
+ mode. For instance, a program compiled with -std=c89 -D_REENTRANT will
+ see a change in the visible declarations, but a program compiled with
+ just -D_REENTRANT, or -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT,
+ will not.
+
+ Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
+ defined by all multithreaded code, but glibc has not required this for
+ many years.
+
+* The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. This
+ means that in a future release, the macros “major”, “minor”, and “makedev”
+ will only be available from <sys/sysmacros.h>.
+
+ These macros are not part of POSIX nor XSI, and their names frequently
+ collide with user code; see for instance glibc bug 19239 and Red Hat bug
+ 130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code
+ presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the
+ problem.
+
+* New <fenv.h> features from TS 18661-1:2014 are added to libm: the
+ fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the
+ femode_t type and the FE_DFL_MODE and FE_SNANS_ALWAYS_SIGNAL macros.
+
+* Integer width macros from TS 18661-1:2014 are added to <limits.h>:
+ CHAR_WIDTH, SCHAR_WIDTH, UCHAR_WIDTH, SHRT_WIDTH, USHRT_WIDTH, INT_WIDTH,
+ UINT_WIDTH, LONG_WIDTH, ULONG_WIDTH, LLONG_WIDTH, ULLONG_WIDTH; and to
+ <stdint.h>: INT8_WIDTH, UINT8_WIDTH, INT16_WIDTH, UINT16_WIDTH,
+ INT32_WIDTH, UINT32_WIDTH, INT64_WIDTH, UINT64_WIDTH, INT_LEAST8_WIDTH,
+ UINT_LEAST8_WIDTH, INT_LEAST16_WIDTH, UINT_LEAST16_WIDTH,
+ INT_LEAST32_WIDTH, UINT_LEAST32_WIDTH, INT_LEAST64_WIDTH,
+ UINT_LEAST64_WIDTH, INT_FAST8_WIDTH, UINT_FAST8_WIDTH, INT_FAST16_WIDTH,
+ UINT_FAST16_WIDTH, INT_FAST32_WIDTH, UINT_FAST32_WIDTH, INT_FAST64_WIDTH,
+ UINT_FAST64_WIDTH, INTPTR_WIDTH, UINTPTR_WIDTH, INTMAX_WIDTH,
+ UINTMAX_WIDTH, PTRDIFF_WIDTH, SIG_ATOMIC_WIDTH, SIZE_WIDTH, WCHAR_WIDTH,
+ WINT_WIDTH.
+
+* New <math.h> features are added from TS 18661-1:2014:
+
+ - Signaling NaN macros: SNANF, SNAN, SNANL.
+
+ - Nearest integer functions: roundeven, roundevenf, roundevenl, fromfp,
+ fromfpf, fromfpl, ufromfp, ufromfpf, ufromfpl, fromfpx, fromfpxf,
+ fromfpxl, ufromfpx, ufromfpxf, ufromfpxl.
+
+ - llogb functions: the llogb, llogbf and llogbl functions, and the
+ FP_LLOGB0 and FP_LLOGBNAN macros.
+
+ - Max-min magnitude functions: fmaxmag, fmaxmagf, fmaxmagl, fminmag,
+ fminmagf, fminmagl.
+
+ - Comparison macros: iseqsig.
+
+ - Classification macros: iscanonical, issubnormal, iszero.
+
+ - Total order functions: totalorder, totalorderf, totalorderl,
+ totalordermag, totalordermagf, totalordermagl.
+
+ - Canonicalize functions: canonicalize, canonicalizef, canonicalizel.
+
+ - NaN functions: getpayload, getpayloadf, getpayloadl, setpayload,
+ setpayloadf, setpayloadl, setpayloadsig, setpayloadsigf, setpayloadsigl.
+
+* The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014,
+ are added to libc. They convert a floating-point number into string.
+
+* Most of glibc can now be built with the stack smashing protector enabled.
+ It is recommended to build glibc with --enable-stack-protector=strong.
+ Implemented by Nick Alcock (Oracle).
+
+* The function explicit_bzero, from OpenBSD, has been added to libc. It is
+ intended to be used instead of memset() to erase sensitive data after use;
+ the compiler will not optimize out calls to explicit_bzero even if they
+ are "unnecessary" (in the sense that no _correct_ program can observe the
+ effects of the memory clear).
+
+* On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined
+ to float instead of double. This does not affect the ABI of any libraries
+ that are part of the GNU C Library, but may affect the ABI of other
+ libraries that use this type in their interfaces.
+
+* On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the
+ float_t and double_t types are now defined to long double instead of float
+ and double. These options are not the default, and this does not affect
+ the ABI of any libraries that are part of the GNU C Library, but it may
+ affect the ABI of other libraries that use this type in their interfaces,
+ if they are compiled or used with those options.
+
+* The getentropy and getrandom functions, and the <sys/random.h> header file
+ have been added.
+
+* The buffer size for byte-oriented stdio streams is now limited to 8192
+ bytes by default. Previously, on Linux, the default buffer size on most
+ file systems was 4096 bytes (and thus remains unchanged), except on
+ network file systems, where the buffer size was unpredictable and could be
+ as large as several megabytes.
+
+* The <sys/quota.h> header now includes the <linux/quota.h> header. Support
+ for the Linux quota interface which predates kernel version 2.4.22 has
+ been removed.
+
+* The malloc_get_state and malloc_set_state functions have been removed.
+ Already-existing binaries that dynamically link to these functions will
+ get a hidden implementation in which malloc_get_state is a stub. As far
+ as we know, these functions are used only by GNU Emacs and this change
+ will not adversely affect already-built Emacs executables. Any undumped
+ Emacs executables, which normally exist only during an Emacs build, should
+ be rebuilt by re-running “./configure; make” in the Emacs build tree.
+
+* The “ip6-dotint” and “no-ip6-dotint” resolver options, and the
+ corresponding RES_NOIP6DOTINT flag from <resolv.h> have been removed.
+ “no-ip6-dotint” had already been the default, and support for the
+ “ip6-dotint” option was removed from the Internet in 2006.
+
+* The "ip6-bytestring" resolver option and the corresponding RES_USEBSTRING
+ flag from <resolv.h> have been removed. The option relied on a
+ backwards-incompatible DNS extension which was never deployed on the
+ Internet.
+
+* The flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG,
+ RES_BLAST defined in the <resolv.h> header file have been deprecated.
+ They were already unimplemented.
+
+* The "inet6" option in /etc/resolv.conf and the RES_USE_INET6 flag for
+ _res.flags are deprecated. The flag was standardized in RFC 2133, but
+ removed again from the IETF name lookup interface specification in RFC
+ 2553. Applications should use getaddrinfo instead.
+
+* DNSSEC-related declarations and definitions have been removed from the
+ <arpa/nameser.h> header file, and libresolv will no longer attempt to
+ decode the data part of DNSSEC record types. Previous versions of glibc
+ only implemented minimal support for the previous version of DNSSEC, which
+ is incompatible with the currently deployed version.
+
+* The resource record type classification macros ns_t_qt_p, ns_t_mrr_p,
+ ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the
+ <arpa/nameser.h> header file because the distinction between RR types and
+ meta-RR types is not officially standardized, subject to revision, and
+ thus not suitable for encoding in a macro.
+
+* The types res_sendhookact, res_send_qhook, re_send_rhook, and the qhook
+ and rhook members of the res_state type in <resolv.h> have been removed.
+ The glibc stub resolver did not support these hooks, but the header file
+ did not reflect that.
+
+* For multi-arch support it is recommended to use a GCC which has
+ been built with support for GNU indirect functions. This ensures
+ that correct debugging information is generated for functions
+ selected by IFUNC resolvers. This support can either be enabled by
+ configuring GCC with '--enable-gnu-indirect-function', or by
+ enabling it by default by setting 'default_gnu_indirect_function'
+ variable for a particular architecture in the GCC source file
+ 'gcc/config.gcc'.
+
+* GDB pretty printers have been added for mutex and condition variable
+ structures in POSIX Threads. When installed and loaded in gdb these pretty
+ printers show various pthread variables in human-readable form when read
+ using the 'print' or 'display' commands in gdb.
+
+* Tunables feature added to allow tweaking of the runtime for an application
+ program. This feature can be enabled with the '--enable-tunables' configure
+ flag. The GNU C Library manual has details on usage and README.tunables has
+ instructions on adding new tunables to the library.
+
+* A new version of condition variables functions have been implemented in
+ the NPTL implementation of POSIX Threads to provide stronger ordering
+ guarantees.
+
+* A new version of pthread_rwlock functions have been implemented to use a more
+ scalable algorithm primarily through not using a critical section anymore to
+ make state changes.
+
+Security related changes:
+
+* On ARM EABI (32-bit), generating a backtrace for execution contexts which
+ have been created with makecontext could fail to terminate due to a
+ missing .cantunwind annotation. This has been observed to lead to a hang
+ (denial of service) in some Go applications compiled with gccgo. Reported
+ by Andreas Schwab. (CVE-2016-6323)
+
+* The DNS stub resolver functions would crash due to a NULL pointer
+ dereference when processing a query with a valid DNS question type which
+ was used internally in the implementation. The stub resolver now uses a
+ question type which is outside the range of valid question type values.
+ (CVE-2015-5180)

+
+* The minimum Linux kernel version that this version of the GNU C Library
+ can be used with is 3.2, except on i[4567]86 and x86_64, where Linux
+ kernel version 2.6.32 or later suffices (on architectures that already
+ required kernel versions more recent than 3.2, those requirements remain
+ unchanged). Linux 3.2 or later kernel headers are required on all
+ architectures.
+
+* The pap_AN locale has been deleted. This has been deprecated for a long
+ time. It has been replaced by pap_AW & pap_CW, both of which have long
+ been included in previous releases.
+
+* The readdir_r and readdir64_r functions have been deprecated. It is
+ recommended to use readdir and readdir64 instead.
+
+* The type “union wait” has been removed. It was deprecated in the early
+ 1990s and never part of POSIX. Application code should use the int type
+ instead of “union wait”.
+
+* A new NSS action is added to facilitate large distributed system
+ administration. The action, MERGE, allows remote user stores like LDAP
+ to be merged into local user stores like /etc/groups in order to provide
+ easy to use, updated, and managed sets of merged credentials. The new
+ action can be used by configuring it in /etc/nsswitch.conf:
+ group: files [SUCCESS=merge] nis
+ Implemented by Stephen Gallagher (Red Hat).
+
+* The deprecated __malloc_initialize_hook variable has been removed from the
+ API.
+
+* The long unused localedef --old-style option has been removed. It hasn't
+ done anything in over 16 years. Scripts using this option can safely
+ drop it.
+
+* nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added to
+ libm. They are defined by TS 18661 and IEEE754-2008. The nextup functions
+ return the next representable value in the direction of positive infinity
+ and the nextdown functions return the next representable value in the
+ direction of negative infinity. These are currently enabled as GNU
+ extensions.

+Security related changes:
+
+* An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It
+ could result in a stack overflow when getnetbyname was called with an
+ overly long name. (CVE-2016-3075)
+
+* Previously, getaddrinfo copied large amounts of address data to the stack,
+ even after the fix for CVE-2013-4458 has been applied, potentially
+ resulting in a stack overflow. getaddrinfo now uses a heap allocation
+ instead. Reported by Michael Petlan. (CVE-2016-3706)
+
+* The glob function suffered from a stack-based buffer overflow when it was
+ called with the GLOB_ALTDIRFUNC flag and encountered a long file name.
+ Reported by Alexander Cherepanov. (CVE-2016-1234)
+
+* The Sun RPC UDP client could exhaust all available stack space when
+ flooded with crafted ICMP and UDP messages. Reported by Aldy Hernandez'
+ alloca plugin for GCC. (CVE-2016-4429)
+
+* The IPv6 name server management code in libresolv could result in a memory
+ leak for each thread which is created, performs a failing naming lookup,
+ and exits. Over time, this could result in a denial of service due to
+ memory exhaustion. Reported by Matthias Schiffer. (CVE-2016-5417)

+
+Version 2.23
+
+* Unicode 8.0.0 Support: Character encoding, character type info, and
+ transliteration tables are all updated to Unicode 8.0.0, using new
+ and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
+ These updates cause user visible changes, such as the fixes for bugs
+ 89, 16061, and 18568.
+
+* sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
+ kernel-internal CPU set size. This means that requests that change the
+ CPU affinity which failed before (for example, an all-ones CPU mask) will
+ now succeed. Applications that need to determine the effective CPU
+ affinities need to call sched_getaffinity or pthread_getaffinity_np after
+ setting it because the kernel can adjust it (and the previous size check
+ would not detect this in the majority of cases).
+
+* The fts.h header can now be used with -D_FILE_OFFSET_BITS=64. With LFS
+ the following new symbols are used: fts64_children, fts64_close,
+ fts64_open, fts64_read and fts64_set.
+
+* getaddrinfo now detects certain invalid responses on an internal netlink
+ socket. If such responses are received, an affected process will
+ terminate with an error message of "Unexpected error <number> on netlink
+ descriptor <number>" or "Unexpected netlink response of size <number> on
+ descriptor <number>". The most likely cause for these errors is a
+ multi-threaded application which erroneously closes and reuses the netlink
+ file descriptor while it is used by getaddrinfo.
+
+* A defect in the malloc implementation, present since glibc 2.15 (2012) or
+ glibc 2.10 via --enable-experimental-malloc (2009), could result in the
+ unnecessary serialization of memory allocation requests across threads.
+ The defect is now corrected. Users should see a substantial increase in
+ the concurent throughput of allocation requests for applications which
+ trigger this bug. Affected applications typically create and
+ destroy threads frequently. (Bug 19048 was reported and analyzed by
+ Ericsson.)
+
+* There is now a --disable-timezone-tools configure option for disabling the
+ building and installing of the timezone related utilities (zic, zdump, and
+ tzselect). This is useful for people who build the timezone data and code
+ independent of the GNU C Library.
+
+* The obsolete header <regexp.h> has been removed. Programs that require
+ this header must be updated to use <regex.h> instead.
+
+* The obsolete functions bdflush, create_module, get_kernel_syms,
+ query_module and uselib are no longer available to newly linked binaries;
+ the header <sys/kdaemon.h> has been removed. These functions and header
+ were specific to systems using the Linux kernel and could not usefully be
+ used with the GNU C Library on systems with version 2.6 or later of the
+ Linux kernel.
+
+* Optimized string, wcsmbs and memory functions for IBM z13.
+ Implemented by Stefan Liebler.
+
+* Newly linked programs that define a variable called signgam will no longer
+ have it set by the lgamma, lgammaf and lgammal functions. Programs that
+ require signgam to be set by those functions must ensure that they use the
+ variable provided by the GNU C Library and declared in <math.h>, without
+ defining their own copy.
+
+* The minimum GCC version that can be used to build this version of the GNU
+ C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
+ still be used to compile programs using the GNU C Library.
+
+Security related changes:
+
+* An out-of-bounds value in a broken-out struct tm argument to strftime no
+ longer causes a crash. Reported by Adam Nielsen. (CVE-2015-8776)
+
+* The LD_POINTER_GUARD environment variable can no longer be used to disable
+ the pointer guard feature. It is always enabled. Previously,
+ LD_POINTER_GUARD could be used to disable security hardening in binaries
+ running in privileged AT_SECURE mode. Reported by Hector Marco-Gisbert.
+ (CVE-2015-8777)
+
+* An integer overflow in hcreate and hcreate_r could lead to an
+ out-of-bounds memory access. Reported by Szabolcs Nagy. (CVE-2015-8778)
+
+* The catopen function no longer has unbounded stack usage. Reported by
+ Max. (CVE-2015-8779)
+
+* The nan, nanf and nanl functions no longer have unbounded stack usage
+ depending on the length of the string passed as an argument to the
+ functions. Reported by Joseph Myers. (CVE-2014-9761)
+
+* A stack-based buffer overflow was found in libresolv when invoked from
+ libnss_dns, allowing specially crafted DNS responses to seize control
+ of execution flow in the DNS client. The buffer overflow occurs in
+ the functions send_dg (send datagram) and send_vc (send TCP) for the
+ NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
+ family. The use of AF_UNSPEC triggers the low-level resolver code to
+ send out two parallel queries for A and AAAA. A mismanagement of the
+ buffers used for those queries could result in the response of a query
+ writing beyond the alloca allocated buffer created by
+ _nss_dns_gethostbyname4_r. Buffer management is simplified to remove
+ the overflow. Thanks to the Google Security Team and Red Hat for
+ reporting the security impact of this issue, and Robert Holiday of
+ Ciena for reporting the related bug 18665. (CVE-2015-7547)

+ 18657, 18676, 18694, 18696, 18887.
+
+* Cache information can be queried via sysconf() function on s390 e.g. with
+ _SC_LEVEL1_ICACHE_SIZE as argument.
+
+* A buffer overflow in gethostbyname_r and related functions performing DNS
+ requests has been fixed. If the NSS functions were called with a
+ misaligned buffer, the buffer length change due to pointer alignment was
+ not taken into account. This could result in application crashes or,
+ potentially arbitrary code execution, using crafted, but syntactically
+ valid DNS responses. (CVE-2015-1781)
+
+* The time zone file parser has been made more robust against crafted time
+ zone files, avoiding heap buffer overflows related to the processing of
+ the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
+ large time zone data files. Overly long time zone specifiers in the TZ
+ variable no longer result in stack overflows and crashes.
+
+* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
+ for LD and GD on x86 and x86-64, has been implemented. You will need
+ binutils-2.24 or later to enable this optimization.
+
+* Character encoding and ctype tables were updated to Unicode 7.0.0, using
+ new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
+ Hat). These updates cause user visible changes, such as the fix for bug
+ 17998.
+
+* CVE-2014-8121 The NSS backends shared internal state between the getXXent
+ and getXXbyYY NSS calls for the same database, causing a denial-of-service
+ condition in some applications.
+
+* Added vector math library named libmvec with the following vectorized x86_64
+ implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
+ pow, powf.
+ The library can be disabled with --disable-mathvec. Use of the functions is
+ enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
+ Shared library libmvec.so is linked in as needed when using -lm (no need to
+ specify -lmvec explicitly for not static builds).
+ Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.
+
+* A new fmemopen implementation has been added with the goal of POSIX
+ compliance. The new implementation fixes the following long-standing
+ issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
+ old implementation is still present for use be by existing binaries.
+
+* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
+ releases. It has been fixed to match 2.19 and older, but binaries built
+ against 2.20 and 2.21 might need to be recompiled. See BZ#18694.
+
+* Port to Native Client running on ARMv7-A (--host=arm-nacl).
+ Contributed by Roland McGrath (Google).
+
+* The header <regexp.h> is deprecated, and will be removed in a future
+ release. Use of this header will trigger a deprecation warning.
+ Application developers should update their code to use <regex.h> instead.
+
+ This header was formerly part of SUS, but was deprecated in 1994 and
+ removed from the standard in 2001. Also, the glibc implementation
+ leaks memory. See BZ#18681 for more details.
+
+Version 2.21
+
+* The following bugs are resolved with this release:
+
+ 6652, 10672, 12674, 12847, 12926, 13862, 14132, 14138, 14171, 14498,

+ 17892.
+
+* CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate
+ too little memory for the to-be-scanned arguments and overflow the
+ allocated buffer. The implementation now correctly computes the required
+ buffer size when using malloc, and switches to malloc from alloca as
+ intended.
+
+* A new semaphore algorithm has been implemented in generic C code for all
+ machines. Previous custom assembly implementations of semaphore were
+ difficult to reason about or ensure that they were safe. The new version
+ of semaphore supports machines with 64-bit or 32-bit atomic operations.
+ The new semaphore algorithm is used by sem_init, sem_open, sem_post,
+ sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.
+
+* Port to Altera Nios II has been contributed by Mentor Graphics.
+
+* Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp
+ implementations for powerpc64/powerpc64le.
+ Implemented by Adhemerval Zanella (IBM).

+* Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
+ and powerpc64le. This may improve lock scaling of existing programs on
+ HTM capable systems. The lock elision code is only enabled with
+ --enable-lock-elision=yes. Also, the TSX lock elision implementation for
+ powerpc will issue a transaction abort on every syscall to avoid side
+ effects being visible outside transactions.
+
+* Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
+ AArch64. Contributed by ARM Ltd.
+
+* i386 memcpy functions optimized with SSE2 unaligned load/store.
+
+* CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
+ under certain input conditions resulting in the execution of a shell for
+ command substitution when the application did not request it. The
+ implementation now checks WRDE_NOCMD immediately before executing the
+ shell and returns the error WRDE_CMDSUB as expected.
+
+* CVE-2012-3406 printf-style functions could run into a stack overflow when
+ processing format strings with a large number of format specifiers.
+
+* CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
+ infinite loop if the DNS response contained a PTR record of an unexpected
+ format.
+
+* The minimum GCC version that can be used to build this version of the GNU
+ C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can
+ still be used to compile programs using the GNU C Library.
+
+* The GNU C Library is now built with -Werror by default. This can be
+ disabled by configuring with --disable-werror.
+
+* New locales: tu_IN, bh_IN, raj_IN, ce_RU.
+
+* The obsolete sigvec function has been removed. This was the original
+ 4.2BSD interface that inspired the POSIX.1 sigaction interface, which
+ programs have been using instead for about 25 years. Of course, ABI
+ compatibility for old binaries using sigvec remains intact.
+
+* Merged gettext 0.19.3 into the intl subdirectory. This fixes building
+ with newer versions of bison.
+
+* Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
+ The original MIPS o32 hard-float ABI requires an FPU where double-precision
+ registers overlay two consecutive single-precision registers. MIPS32R2
+ introduced a new FPU mode (FR=1) where double-precision registers extend the
+ corresponding single-precision registers which is incompatible with the
+ o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
+ require the use of FR=1 making a transition necessary. New o32 ABI
+ extensions enable users to migrate over time from the original o32 ABI
+ through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
+ tracks the ABI of any loaded object and verifies that new objects are
+ compatible. Mode transitions will also be requested as required and
+ unsupportable objects will be rejected. The ABI checks include both soft and
+ hard float ABIs for o32, n32 and n64.
+
+ GCC 5 with GNU binutils 2.25 onwards:
+ It is strongly recommended that all o32 system libraries are built using the
+ new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
+ with the original and all new o32 ABI extensions. Configure a MIPS GCC
+ compiler using --with-fp-32=xx to set this by default.

+Version 2.20
+
+* The following bugs are resolved with this release:
+
+ 6804, 9894, 11505, 12994, 13347, 13651, 14308, 14770, 15119, 15132, 15347,

+ 16275, 16284, 16287, 16315, 16348, 16349, 16354, 16357, 16362, 16447,
+ 16516, 16532, 16539, 16545, 16561, 16562, 16564, 16574, 16599, 16600,

+ 16642, 16648, 16649, 16670, 16674, 16677, 16680, 16681, 16683, 16689,
+ 16695, 16701, 16706, 16707, 16712, 16713, 16714, 16724, 16731, 16739,

+ 16796, 16799, 16800, 16815, 16823, 16824, 16831, 16838, 16839, 16849,
+ 16854, 16876, 16877, 16878, 16882, 16885, 16888, 16890, 16892, 16912,
+ 16915, 16916, 16917, 16918, 16922, 16927, 16928, 16932, 16943, 16958,
+ 16965, 16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022,
+ 17031, 17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078,
+ 17079, 17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150,
+ 17153, 17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354.
+
+* Reverted change of ABI data structures for s390 and s390x:
+ On s390 and s390x the size of struct ucontext and jmp_buf was increased in
+ 2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
+ of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
+ are preserved pointing straight to the same implementation as the old ones.
+ Given that, new callers will simply provide a too-big buffer to these
+ functions. Any applications/libraries out there that embed jmp_buf or
+ ucontext_t in an ABI-relevant data structure that have already been rebuilt
+ against 2.19 headers will have to rebuilt again. This is necessary in any
+ case to revert the breakage in their ABI caused by the glibc change.
+
+* Support for file description locks is added to systems running the
+ Linux kernel. The standard file locking interfaces are extended to
+ operate on file descriptions, not file descriptors, via the use of
+ F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
+ are associated with an open file instead of a process.
+
+* Optimized strchr implementation for AArch64. Contributed by ARM Ltd.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+ can be used with is 2.6.32.
+
+* Running the testsuite no longer terminates as soon as a test fails.
+ Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
+ with PASS or FAIL lines for individual tests. A summary of the results is
+ printed, including a list of failing lists, and "make check" exits with
+ error status if there were any unexpected failures. "make check
+ stop-on-test-failure=y" may be used to keep the old behavior.
+
+* The am33 port, which had not worked for several years, has been removed
+ from ports.
+
+* The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
+ supported; they now act the same as _DEFAULT_SOURCE (but generate a
+ warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
+ conflicted with POSIX (support for which was removed in 2.19), the
+ interfaces those macros enabled remain available when compiling with
+ _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
+ test macros defined.
+
+* Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd.
+
+* Added support for TX lock elision of pthread mutexes on s390 and s390x.
+ This may improve lock scaling of existing programs on TX capable systems.
+ The lock elision code is only built with --enable-lock-elision=yes and
+ then requires a GCC version supporting the TX builtins. With lock elision
+ default mutexes are elided via __builtin_tbegin, if the cpu supports
+ transactions. By default lock elision is not enabled and the elision code
+ is not built.
+
+* CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
+ copy the path argument. This allowed programs to cause posix_spawn to
+ deference a dangling pointer, or use an unexpected pathname argument if
+ the string was modified after the posix_spawn_file_actions_addopen
+ invocation.
+
+* All supported architectures now use the main glibc sysdeps directory
+ instead of some being in a separate "ports" directory (which was
+ distributed separately before glibc 2.17).
+
+* The NPTL implementation of POSIX pthreads is no longer an "add-on".
+ On configurations that support it (all Linux configurations), it's now
+ used regardless of the --enable-add-ons switch to configure. It is no
+ longer possible to build such configurations without pthreads support.
+
+* Locale names, including those obtained from environment variables (LANG
+ and the LC_* variables), are more tightly checked for proper syntax.
+ setlocale will now fail (with EINVAL) for locale names that are overly
+ long, contain slashes without starting with a slash, or contain ".." path
+ components. (CVE-2014-0475) Previously, some valid locale names were
+ silently replaced with the "C" locale when running in AT_SECURE mode
+ (e.g., in a SUID program). This is no longer necessary because of the
+ additional checks.
+
+* On x86-64, the dynamic linker's lazy-binding support is now compatible
+ with application code using Intel MPX instructions. (With all previous
+ versions, the MPX register state could be clobbered when making calls
+ into or out of a shared library.) Note that while the new dynamic
+ linker is compatible with all known x86 hardware whether or not it
+ supports Intel MPX, some x86 instruction-set emulators might fail to
+ handle the new instruction encodings. This is known to affect Valgrind
+ versions up through 3.9 (but will be fixed in the forthcoming 3.10
+ release), and might affect other tools that do instruction emulation.
+
+* Support for loadable gconv transliteration modules has been removed.
+ The support for transliteration modules has been non-functional for
+ over a decade, and the removal is prompted by security defects. The
+ normal gconv conversion modules are still supported. Transliteration
+ with //TRANSLIT is still possible, and the //IGNORE specifier
+ continues to be supported. (CVE-2014-5119)
+
+* Decoding a crafted input sequence in the character sets IBM933, IBM935,
+ IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
+ resulting a denial-of-service security vulnerability in applications which
+ use functions related to iconv. (CVE-2014-6040)
+
+Version 2.19
+
+* The following bugs are resolved with this release:

+ 16431, 16453, 16474, 16506, 16510, 16529
+
+* Slovenian translations for glibc messages have been contributed by the
+ Translation Project's Slovenian team of translators.
+
+* The public headers no longer use __unused nor __block. This change is to
+ support compiling programs that are derived from BSD sources and use
+ __unused internally, and to support compiling with Clang's -fblock
+ extension which uses __block.
+
+* CVE-2012-4412 The strcoll implementation caches indices and rules for
+ large collation sequences to optimize multiple passes. This cache
+ computation may overflow for large collation sequences and may cause a
+ stack or buffer overflow. This is now fixed to use a slower algorithm
+ which does not use a cache if there is an integer overflow.
+
+* CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
+ rules for large collation sequences to optimize multiple passes and falls
+ back to alloca if malloc fails, resulting in a possible stack overflow.
+ The implementation now falls back to an uncached collation sequence lookup
+ if malloc fails.
+
+* CVE-2013-4788 The pointer guard used for pointer mangling was not
+ initialized for static applications resulting in the security feature
+ being disabled. The pointer guard is now correctly initialized to a
+ random value for static applications. Existing static applications need
+ to be recompiled to take advantage of the fix (bug 15754).
+
+* CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
+ to the d_name member of struct dirent, or omit the terminating NUL
+ character. (Bugzilla #14699).
+
+* CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
+ aligned_alloc functions could allocate too few bytes or corrupt the
+ heap when passed very large allocation size values (Bugzilla #15855,
+ #15856, #15857).
+
+* CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
+ for AF_INET6 has been fixed (Bugzilla #16072).
+
+* New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
+ pap_CW, quz_PE, the_NP.
+
+* Substantially revised locales: gd_GB, ht_HT
+
+* The LC_ADDRESS field was updated to support country_car for almost all
+ supported locales.
+
+* ISO 1427 definitions were updated.
+
+* ISO 3166 definitions were updated.
+
+* The localedef utility now supports --big-endian and --little-endian
+ command-line options to generate locales for a different system from that
+ for which the C library was built.
+
+* Binary locale files now only depend on the endianness of the system for
+ which they are generated and not on other properties of that system. As a
+ consequence, binary files generated with new localedef may be incompatible
+ with old versions of the GNU C Library, and binary files generated with
+ old localedef may be incompatible with this version of the GNU C Library,
+ in the following circumstances:
+
+ + Locale files may be incompatible on m68k systems.
+
+ + Locale archive files (but not separate files for individual locales) may
+ be incompatible on systems where plain "char" is signed.
+
+* The configure option --disable-versioning has been removed. Builds with
+ --disable-versioning had not worked for several years.
+
+* ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
+ cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
+
+* SystemTap probes for malloc have been introduced.
+
+* SystemTap probes for slow multiple precision fallback paths of
+ transcendental functions have been introduced.
+
+* Support for powerpc64le has been added.
+
+* The soft-float powerpc port now supports e500 processors.
+
+* Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
+
+* A new feature test macro _DEFAULT_SOURCE is available to enable the same
+ set of header declarations that are enabled by default, even when other
+ feature test macros or compiler options such as -std=c99 would otherwise
+ disable some of those declarations.
+
+* The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
+ conflict with POSIX. The libbsd-compat library (which was a dummy library
+ that did nothing) has also been removed.
+
+* Preliminary documentation about Multi-Thread, Async-Signal and
+ Async-Cancel Safety has been added.
+
+* Change of ABI data structures for s390 and s390x:
+ On s390 and s390x the size of struct ucontext and jmp_buf was increased to
+ allow for future hardware extensions. All library functions that accept or
+ return these structures were versioned in order to provide backwards
+ compatibility with existing code. However, not all cases can be handled
+ with interface versioning. If an application embeds either structure into
+ another structure and that structure is passed to another compilation unit
+ which expects the newer larger-sized object then any access to the new
+ fields will result in undefined behaviour. Similarly any access to fields
+ that were moved by the enlarging of the structures will cause undefined
+ behaviour. To fix the undefined behaviour all objects that are part of the
+ final in-memory image must agree on the size of structures, and this may
+ require recompilation.
+
+Version 2.18

+ 15755, 15759.
+
+* CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
+ has been fixed by disabling the use of pt_chown (Bugzilla #15755).
+ Distributions can re-enable building and using pt_chown via the new configure
+ option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
+ considerable security risks and should only be used if the distribution
+ understands and accepts the risks.
+
+* CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
+ #15078).
+
+* CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
+ fixed (Bugzilla #15330).
+
+* Add support for calling C++11 thread_local object destructors on thread
+ and program exit. This needs compiler support for offloading C++11
+ destructor calls to glibc.
+
+* Improved worst case performance of libm functions with double inputs and
+ output.
+
+* Support for priority inherited mutexes in pthread condition variables on
+ non-x86 architectures.
+
+* Port to Xilinx MicroBlaze contributed by David Holsgrove.
+
+* Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
+
+* Optimized string functions for ARM. Implemented by Will Newton and
+ Richard Henderson.
+
+* Optimized libm functions for SPARC. Implemented by David S. Miller.
+
+* Support for building more of ARM glibc as Thumb-2 code. Implemented by
+ Richard Henderson.
+
+* Support for building most of MIPS glibc as MIPS16 code. Implemented by
+ Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
+
+* Added a benchmark framework to track performance of functions in glibc.
+
+* New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
+ It is based on draft TS 18661 and currently enabled as a GNU extension.
+
+* On Linux, the clock function now uses the clock_gettime system call
+ for improved precision, rather than old times system call.
+
+* Added support for version-3 tz format files. This is needed when using
+ the tz database release 2013e or later, and affects a few unusual cases --
+ currently only TZ='America/Godthab' for time stamps after 2037.
+
+* Added new API functions pthread_getattr_default_np and
+ pthread_setattr_default_np to get and set the default pthread
+ attributes of a process.
+
+* Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
+ This may improve lock scaling of existing programs on TSX capable systems.
+ When the --enable-lock-elision=yes parameter is specified at configure
+ time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
+ mutexes.
+
+* Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
+ availability). Implemented by Ryan S. Arnold.
+
+* Support added for POWER8 platform. Implemented by Ryan S. Arnold.

+ 14879, 14889, 14893, 14898, 14914.
+
+* Optimization of memcpy for MIPS.
+
+* CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
+ EMFILE has been fixed (Bugzilla #14889).
+
+* The add-on ports collection is now distributed in the "ports" subdirectory
+ of the main GNU C Library distribution, rather than separately.
+
+* Port to ARM AArch64 contributed by Linaro.
+
+* Support for STT_GNU_IFUNC symbols added for s390 and s390x.
+ Optimized versions of memcpy, memset, and memcmp added for System z10 and
+ zEnterprise z196.
+ Implemented by Andreas Krebbel.
+
+* The new function secure_getenv allows secure access to the environment,
+ returning NULL if running in a SUID/SGID process. This function replaces
+ the internal function __secure_getenv.
+
+* SystemTap static probes have been added into the dynamic linker.
+ Implemented by Gary Benson.
+
+* Optimizations of string functions strstr, strcasestr and memmem.
+ Implemented by Maxim Kuvyrkov.
+
+* The minimum Linux kernel version that this version of the GNU C Library
+ can be used with is 2.6.16.
+
+* Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
+ powerpc POWER7. Implemented by Will Schmidt.
+
+* New configure option --disable-nscd builds the C library such that it
+ never attempts to contact the Name Service Caching Daemon (nscd).
+ New configure option --disable-build-nscd avoids building nscd itself;
+ this is the default if --disable-nscd is used.
+
+* Improved support for cross-compilation, including cross-testing and
+ bootstrap builds without a previously built glibc.
+
+* Several testsuite tests are now able to test multiple IFUNC variants of an
+ interface, rather than just testing the one that would be chooen by
+ default.
+
+* New configure options --with-bugurl and --with-pkgversion, for
+ distributors to use to embed their bug-reporting and package version
+ information in --help and --version output.
+
+* The ttyname and ttyname_r functions on Linux now fall back to searching for
+ the tty file descriptor in /dev/pts or /dev if /proc is not available. This
+ allows creation of chroots without the procfs mounted on /proc.
+
+* The `crypt' function now fails if passed salt bytes that violate the
+ specification for those values. On Linux, the `crypt' function will
+ consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
+ enabled, and fail on encrypted strings using the MD5 or DES algorithm
+ when the mode is enabled.
+
+* The `clock_*' suite of functions (declared in <time.h>) is now available
+ directly in the main C library. Previously it was necessary to link with
+ -lrt to use these functions. This change has the effect that a
+ single-threaded program that uses a function such as `clock_gettime' (and
+ is not linked with -lrt) will no longer implicitly load the pthreads
+ library at runtime and so will not suffer the overheads associated with
+ multi-thread support in other code such as the C++ runtime library.
+
+* New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
+ sat_IN, and szl_PL.

+ 14277, 14278.
+
+* Support for the x32 ABI on x86-64 added. The x32 target is selected by
+ configuring glibc with:
+ BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
+ Visit <https://sites.google.com/site/x32abi/> for more x32 ABI info.
+ Implemented by H.J. Lu.
+
+* ISO C11 support:
+
+ + define static_assert
+
+ + do not declare gets
+
+ + declare at_quick_exit and quick_exit also for ISO C11
+
+ + aligned_alloc. NB: The code is deliberately allows the size parameter
+ to not be a multiple of the alignment. This is a moronic requirement
+ in the standard but it is only a requirement on the caller, not the
+ implementation.
+
+ + timespec_get added
+
+ + uchar.h support added
+
+ + CMPLX, CMPLXF, CMPLXL added
+
+ Implemented by Ulrich Drepper.
+
+* Support for the IA-64 has been moved to ports.
+
+* Remove support for anything but ELF binary format
+
+* Checking versions of poll, ppoll added.
+ Implemented by Ulrich Drepper.
+
+* More generic and 64-bit performance optimizations to math functions.
+ Implemented by Ulrich Drepper.
+
+* New configure option --enable-obsolete-rpc makes the deprecated RPC
+ headers and functions available at compile time as they were before
+ version 2.14. This option will be removed at some time in the future
+ after the TI-RPC library becomes fully sufficient for the needs of
+ existing applications.
+
+* Compatibility code for Linux kernel versions before 2.4 has been removed.
+ Note that glibc is not expected to work with any Linux kernel version
+ before 2.6.
+
+* New header <sys/auxv.h> and function getauxval allowing easy access to
+ the AT_* key-value pairs passed from the Linux kernel. The header also
+ defines the HWCAP_* bits associated with the AT_HWCAP key.
+
+* New locales: mag_IN
+
+* New configure option --enable-systemtap builds SystemTap static probes
+ into libc for setjmp and longjmp and into libpthread for various operations.
+ So far the setjmp/longjmp probes and some of the libpthread probes are
+ provided only for i*86 and x86_64.
+ Implemented by Roland McGrath and Rayson Ho.
+
+* Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
+
+* More optimized functions for PowerPC. Implemented by Adhemerval Zanella
+ and Will Schmidt.
+
+* More optimized functions for SPARC. Implemented by David S. Miller.
+
+* Improved support for cross-compilation, especially bootstrap builds
+ without a previously built glibc.
+
+* Ports for the TILE-Gx and TILEPro families of processors. Contributed by
+ Chris Metcalf from Tilera.
+
+* Support for the old ARM ABI has been removed from ports. Only the EABI is
+ now supported for ARM processors.
+
+* The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
+ as the name of the dynamic linker, to distinguish it from the
+ /lib/ld-linux.so.3 dynamic linker used for the base EABI.
+
+* Support for CRIS has been removed from ports.
+
+* A new class of installed header has been documented for low-level
+ platform-specific functionality. PowerPC added the first instance with a
+ function to provide time base register access. Contributed by Tulio
+ Magno Quites Machado Filho.
+
+* ix86 configurations now install header files that are consistent with
+ what x86-64 configurations install. These same header files can be used
+ for -m32, -m64, or -mx32 builds.
+ Contributed by H.J. Lu.
+
+* Math library bug fixes. A thorough audit of all open math library bugs was
+ conducted by Joseph Myers. Significant progress was made on many math
+ library bugs resulting in more accurate exceptions and function results.
+ Many thanks to all those that contributed including Andreas Jaeger for his
+ patch review and work on the x87 trigonometric instruction issues.
+
+* Timezone data is no longer installed. Timezone-related binaries and scripts
+ will continue to be installed. Users should obtain their timezone data from
+ their distribution provider or from the tzdata package at
+ <ftp://munnari.oz.au/pub/>.
+

+ 12795, 12811, 12813, 12814, 12841
+
+* The RPC implementation in libc is obsoleted. Old programs keep working
+ but new programs cannot be linked with the routines in libc anymore.
+ Programs in need of RPC functionality must be linked against TI-RPC.
+ The TI-RPC implementation is IPv6 enabled and there are other benefits.
+
+ Visible changes of this change include (obviously) the inability to link
+ programs using RPC functions without referencing the TI-RPC library and the
+ removal of the RPC headers from the glibc headers.
+ Implemented by Ulrich Drepper.
+
+* New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
+ syncfs, setns, sendmmsg
+
+* New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
+ yue_HK, lij_IT, mhr_RU
+
+* New encodings: CP770, CP771, CP772, CP773, CP774
+
+* New program sotruss to trace calls through PLTs
+ Implemented by Ulrich Drepper.
+
+* The malloc hook implementation is marked deprecated and will be removed
+ from the default implementation in the next version. The design never
+ worked ever since the introduction of threads. Even programs which do
+ not create threads themselves can use multiple threads created internally.
+
+Version 2.13

+ Implemented by Ulrich Drepper.
+
+* Implement second fallback mode for optimized DNS lookup for even more
+ broken environments. If two requests from the same port are not
+ handled correctly close the socket and open a new one before sending
+ the second request. The 'single-request-reopen' option in /etc/resolv.conf
+ can be used to select this mode right away, instead of rediscovering the
+ necessity is every process again.
+ Implemented by Ulrich Drepper.
+

+
+* Correct declarations of string function when used in C++ code. This
+ could lead to compile errors for invalid C++ code.

+* XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are
+ now in POSIX.
+
+* New POSIX 2008 interface: psiginfo
+ Implemented by Ulrich Drepper.
+
+* New ISO C++1x interfaces: quick_exit, at_quick_exit
+ Implemented by Ulrich Drepper.
+
+* Support for selecting between multiple function definitions at runtime
+ using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
+
+* The libcrypt library can now use the hash function implementations in
+ NSS. Implemented by Ulrich Drepper.
+
+* The malloc implementation can be compiled to be less memory efficient
+ but higher performing in multi-threaded programs.
+ Implemented by Ulrich Drepper.
+
+* New locales: nan_TW@latin, ks_IN
+
+* Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
+ Implemented by Ulrich Drepper.
+
+* Extended printf hook support. It is possible to use user-defined types
+ and extend existing format specifiers.
+ Implemented by Ulrich Drepper.
+
+* Handling for group shadow files has been added.
+ Implemented by Ulrich Drepper.
+
+* DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
+ servers (the case, e.g., for some people using the built-in DNS
+ server in ADSL modems/routers). There is a once-per-process timeout
+ in case of a broken server. To avoid it, users can run nscd or put
+ 'options single-request' in /etc/resolv.conf.
+ Implemented by Ulrich Drepper.

+ implicitly add a NUL byte and seeks from the end of the buffer really
+ use the buffer end, not the string length as the basis.
+ Implemented by Ulrich Drepper.
+
+* Many functions, exported and internal, now atomically set the close-on-exec
+ flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
+
+* Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
+ Sinhala)
+ Implemented by Pravin Satpute.

+ Implemented by Ulrich Drepper.
+
+* New Linux interfaces: splice, tee, sync_file_range, vmsplice.
+
+* New iconv module for MIK. Contributed by Alexander Shopov.
+
+* For sites with broken group and/or passwd database, the auto-propagate
+ option of nscd can prevent creating ID lookup entries from the results
+ of a name lookup and vice versa. This usually is no problem but some
+ site might have problems with the default behavior.
+ Implemented by Ulrich Drepper.
+
+* Iterating over entire database in NIS can be slow. With the
+ SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
+ to trade time for memory. The entire database will be read at once.
+ Implemented by Ulrich Drepper.
+
+* The interfaces introduced in RFC 3542 have been implemented by
+ Ulrich Drepper.
+
+* Support for the new ELF hash table format was added by Ulrich Drepper.

+
+* It is now possible to install audit libraries for the dynamic linker using
+ LD_AUDIT. Implemented by Ulrich Drepper.
+
+* The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
+ longer supported. The new NPTL implementation requires Linux 2.6 kernels.
+ For a libc and libpthread that works well on Linux 2.4 kernels, we
+ recommend using the stable 2.3 branch.
+
+* The new function open_wmemstream acts like open_memstream,
+ but uses a wchar_t wide character buffer.
+
+* The new function ppoll is an improved version of poll, similar to pselect.

+* New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
+ futimesat, faccessat, mkdirat, mkfifoat, mknodat,
+ renameat, unlinkat, linkat, symlinkat, readlinkat.
+
+* New Linux kernel system calls: unshare,
+ inotify_init, inotify_add_watch, inotify_rm_watch.
+
+* The euidaccess function is now also known by the alias eaccess,
+ for compatibility with some other systems.
+
+* Timezone data updated to 2006b version.

+
+Version 2.3.4
+
+* Support for RFC 3678. Real implementations exist only for Linux so far.
+ Implemented by Ulrich Drepper.
+
+* nscd can now cache entries persistently. Expiring entries are reloaded.
+ For speedups the cache can be shared in memory with client processes.
+ Implemented by Ulrich Drepper.
+
+* nscd can now perform SELinux checks.
+ Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
+
+* getaddrinfo queries are now cached. Canonical name lookup is performed
+ efficiently.
+ Implemented by Ulrich Drepper.
+
+* The nothrow function attribute is used when headers are used by gcc when
+ compiling C code. This can avoid significant amounts of exception
+ handling data.
+
+* The malloc functions perform more error checking and are stricter when
+ it comes to reacting on errors. The default action is to terminate
+ the process after showing an error message. Implemented by Ulrich Drepper.
+
+* Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
+ lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
+
+* Namespaces in ld.so are implemented. DSOs can be loaded in separate
+ namespaces using the new function dlmopen(). This feature is of course,
+ like most other dynamic loading functionality, not available in statically
+ linked applications. Implemented by Ulrich Drepper.
+
+* Low-overhead boundary checking variants of string and some stdio functions
+ were added. These are to be used in conjunction with a gcc patch by
+ Jakub Jelinek which adds calls to these functions if possible.
+ Implemented by Jakub Jelinek and Ulrich Drepper.
+
+* Old code for several operating systems and machine architectures that
+ have not been in working condition in a long time have been removed from
+ the main source tree maintained by the GNU C Library's maintainers.
+ These files are now reside in the separate `ports' source module
+ that is usable as an add-on when building the library.
+
+Version 2.3.3
+
+* New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
+ interrogate the dynamic linker, compatible with the Solaris interface.
+
+* ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
+ implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
+
+* getifaddrs now uses the netlink interface on Linux to get its information.
+ Implemented by Thorsten Kukuk.
+
+* getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
+ Implemented by Ulrich Drepper.
+
+* support for non-executable stacks on x86 has been added. Changes mostly
+ by Roland McGrath.
+
+* regex is now much faster for multibyte locales. Changes by Jakub Jelinek
+ and Ulrich Drepper.
+
+* getaddrinfo now performs destination address selection according to
+ RFC 3484.
+
+Version 2.3.2
+
+* Thread-safe interfaces for many functions that access locale data
+ were added in version 2.3, but these features were omitted from NEWS.
+ Many functions have variants with an `_l' suffix that take a `locale_t'
+ object as a parameter rather than consulting the current locale.
+ The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
+ create and maintain `locale_t' objects. Additionally, the new function
+ `uselocale' sets "the current locale" (as used by functions not so
+ parameterized) set for an individual thread. These features were added
+ in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
+
+* The functions getresuid, getresgid, setresuid, and setresgid, which
+ have long been available on Linux, are now declared in <unistd.h>
+ and are now also available on the Hurd.
+
+* ELF thread-local storage support (TLS) now works on x86-64.
+
+* The new dynamic string token $LIB is expanded in shared library names.
+ This normally expands to lib, but on some 64-bit platforms to lib64 instead.
+
+* Aldy Hernandez contributed complete software floating point support for
+ PowerPC machines with no FPU.
+
+* fexecve is implemented on Linux.
+
+* The `btowc' function should work at least twice as fast due to
+ specialized callbacks in the iconv modules. Implemented by Bruno Haible.
+
+* With approriate thread add-ons cancelable functions are now implemented
+ in libc.so as well. No need to call the function in libpthread. This
+ change allowed to finally disable the incorrect and expensive handling
+ of weak definition in ld.so.
+
+* Yet more PLT entries in libc.so have been removed. We finally arrived
+ at the bare minimum. Startup times improved appropriately.
+
+* Support for the new Linux/x86 system call interface was added. The
+ AT_SYSINFO auxiliary vector entry is recognized and handled.
+
+Version 2.3
+
+* Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
+ charsets.
+
+* iconv (the program and the interface) now accepts empty names (excluding
+ options like //TRANSLIT) to mean "use charset of current locale".
+
+* localedef can now transliterate characters in strings which are not in
+ the provided charmap. The information from the input locale is used.
+
+* Prelinking support was added for ELF targets. This requires additional
+ tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
+
+* Read-only stdio streams now use mmap to speed up operation by eliminating
+ copying and buffer underflows. To use add 'm' to the mode string of
+ the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
+
+* The malloc functions were completely rewritten by Wolfram Gloger based
+ on Doug Lea's malloc-2.7.0.c.
+
+* Isamu Hasegawa contributed a completely new and POSIX-conformant
+ implementation of regex.
+
+* Bruno Haible upgraded the iconv and locale implementation to support
+ Unicode 3.2.
+
+* Contents of the LC_* and LANG environment variables in the CEN style are
+ not recognized anymore. It never was used. Change by Ulrich Drepper.
+
+* The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
+ thread-local storage (TLS) ABI on some platforms.
+ Changes by Ulrich Drepper. SH support by Kaz Kojima.
+
+* Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
+ EUC-JISX0213, and TSCII.
+
+* New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
+ BSD-compatible interface for getting all network interface addresses.
+ Implementation for IPv4 by Roland McGrath.
+
+* Loading of locale data is faster due to the introduction of a locale
+ archive. Implemented by Roland McGrath and Ulrich Drepper.
+
+* Startup times are significantly reduced by not using exported functions
+ inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
+ and Ulrich Drepper.
+
+* Steven Munroe contributed a port to PowerPC64/Linux.
+
+Version 2.2.6
+
+* The Hurd now uses the GNU libio implementation of stdio rather than the
+ old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
+
+* The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
+ with the same behavior as the Linux system call of the same name.
+
+Version 2.2.5
+
+* Stephen Moshier implemented log2, log10, powl and cbrtl for the
+ 128-bit long double format.
+
+* Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
+ IBM1161, and IBM1162 charsets.
+
+* Andreas Jaeger contributed a port to x86-64/Linux.
+
+* Peter Bruin contributed a port to PowerPC/Hurd.
+
+* libc functions using I/O streams now can handle wide-oriented streams
+ as well.
+
+* optimizations in the dynamic linker. Binaries created by recent binutils
+ versions start up quicker due to reduced time spent on relocations.
+
+* Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
+
+Version 2.2.4
+
+* Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
+ asinh, atanh, j0 for the 128-bit long double format.
+
+* Bruno Haible updated all the code handling Unicode in some form to
+ support Unicode 3.1.
+
+* Speed of regex for single-byte locales is back to previous levels.
+ Patch by Isamu Hasegawa.
+
+* Alpha, SPARC, and IA-64 now also using floating stacks.
+
+* Startup time of internationalized applications greatly improved through
+ iconv cache. Use iconvconfig to generate the cache file.
+ Contributed by Ulrich Drepper.
+
+* The IA-64 specific part of ld.so was rewritten to eliminate some pretty
+ severe performance problems. Patch by David Mosberger.
+
+* The Hurd port got a lot more functionality like AIO, various stdio
+ extensions, etc. Mainly done by Roland McGrath.
+
+* mtrace can now lookup symbols in shared libraries.
+
+Version 2.2.3
+
+* Intel's IA-64 math library is largely integrated. It provides fast and
+ accurate implementatations for most basic and standard math functions
+ in float, double, and long double format.
+
+* Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
+ and asin for the 96-bit long double format and asin, log, tan for the
+ 128-bit long double format.
+
+* The beginning of a last-bit accurate math library by IBM Haifa were added.
+ The basic double functions exist today. Contributed by Abraham Ziv
+ <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
+ <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
+
+* An asynchronous name lookup library was added. The interface is designed
+ after POSIX AIO. The proposal was circulated beforehand to get comments.
+ No negative ones came in. Implemented by Ulrich Drepper.
+
+* Port to S390/64bit contributed by Martin Schwidefsky
+ <schwidefsky@de.ibm.com>.
+
+* David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
+ of functions for Linux/IA-64.
+
+* The RPC code is now thread safe. Threads can now use the same service
+ of different services at the same time. Patch by Eric Norum
+ <eric.norum@usask.ca> with some help by Ulrich Drepper.
+
+* Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
+ family of functions for Linux/S390.
+
+* Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
+ of functions for Linux/x86.
+
+* Port to Linux/CRIS contributed by Axis Communications.
+
+Version 2.2.2
+
+* Lots of headers were cleaned up. Using the tool in the conform/ subdir
+ we can now check for namespace violations and missing declarations. The
+ result is that almost all headers are now Unix-compliant (as defined in
+ the upcoming XPG6). The negative side is that some programs might need
+ corrections, too, if they depend on the incorrect form of the headers in
+ previous versions which defined too many symbols and included too many
+ other headers.
+
+* regex now handles multibyte character sets correctly.
+ Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
+
+* iconv (the program) does now conform to the upcoming XPG6 and handles
+ charmaps. Instead of the charset names the path of charmaps can be
+ provided and the conversion happens based on this data.
+ Contributed by Ulrich Drepper.
+
+* The locale program now provides detailed information about the installed
+ locales. While
+
+ locale -a
+
+ only lists the names of the supported locales
+
+ locale -a --verbose
+
+ provides details such as country, language, and codeset name.
+ Contributed by Ulrich Drepper.
+
+Version 2.2.1
+
+* The gencat program now parses the input file according to the charset
+ selected by the LC_CTYPE category. This is important for stateful
+ character sets. To make generating catalogs easier there is a way
+ to overwrite the charset selected by the locale: before the first
+ message or $ quote line the catalog can contain a line like
+
+ $ codeset=ISO-8859-2
+
+ to select the charset (ISO-8859-2 in this case).
+
+ Implemented by Shinya Hanataka and Ulrich Drepper.
+
+* New codeset conversion modules: IBM-922 (Estonia PC codeset),
+ IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
+ Contributed by Masahide Washizawa <washi@jp.ibm.com>.
+
+* Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
+ <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
+
+* The LANGUAGE environment variable is now ignored unless the locale is
+ changed from the default "C" locale.
+
+* The usual bug fixes.
+
+Version 2.2
+
+* Greg McGary added runtime support for bounds checking using gcc's
+ new -fbounded-pointers option. ix86 target is complete. PowerPC
+ is in progress.
+
+* Thorsten Kukuk added secure mode support to nscd.
+
+* The Berkeley db libraries have been removed.
+
+ Related, the nss_db module is now in a separate package since it
+ obviously requires a database library being available.
+
+* Wide character I/O streams implemented by Ulrich Drepper.
+
+* Functions from the extended socket API added by Ulrich Drepper.
+
+* Functions feenableexcept and fedisableexcept to control the
+ behaviour of individual exceptions have been added by Andreas Jaeger.
+
+* ldconfig program added by Andreas Jaeger and Jakub Jelinek.
+
+* The resolver code has been updated from bind 8.2.3-T5B which supports
+ threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
+ and Mark Kettenis.
+
+ This change could in some situations effect backward compatibility. Since
+ now `_res' is a thread-local instead of a global variable, modifying it
+ in one thread does not have any effect in other threads.
+
+ The resolver library was also extended to allow IPv6 as the transport
+ protocol for the requests. This work was done by Stig Venaas.
+
+* Compatibility code for K&R C compilers has been removed from the
+ header files. A ISO C compiler is needed to use the library
+ (conforming to either C89 or C99 standard).
+
+* Complete rewrite of the localedef program to support multibyte character
+ sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
+ strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
+ Implemented by Ulrich Drepper.
+
+ Bruno Haible significantly improved the generation and use of the data
+ structures for the wide character tables.
+
+* Plural handling in gettext implemented by Ulrich Drepper.
+
+* The utmp daemon has been removed.
+
+* The port to MIPS-Linux has been finished by Andreas Jaeger.
+
+* A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
+ and Yutaka Niibe.
+
+* POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
+
+* POSIX barriers implemented by Kaz Kylheku.
+
+* POSIX spawn function family implemented by Ulrich Drepper.
+
+* POSIX spinlocks are now available.
+
+* Timed wait functions for mutex, rwlock, and semaphores are implemented.
+
+* the configure option --enable-kernel=X.Y.Z allows to strip out
+ compatibility for kernel versions before X.Y.Z. This is currently only
+ implemented for Linux.
+
+* the sockaddr_in6 structure changed. The IPv6 working group added a new
+ field sin6_scope_id. This means that all programs using IPv6 should be
+ recompiled. Don't expect binary compatibility with previous glibc
+ versions.
+
+* various conversion modules for IBM character sets contributed by
+ Masahide Washizawa.
+
+* IA-64 port by Jes Sorensen and HJ Lu.
+
+Version 2.1.3
+
+* bug fixes
+
+
+Version 2.1.2
+
+* bug fixes
+
+
+Version 2.1.1
+
+* New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
+
+* New xdr functions are added; some rpc functions are now 64bit clean.
+
+* Fixed a number of bugs and memory leaks (especially in NIS+ code).
+
+* Fixed known incompatibilities with glibc 2.0.
+
+* New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
+
+* Optimized a number of functions (especially the ELF dynamic loader).
+
+* Update timezone data files.
+
+* lots of charmaps corrections
+
+* some new locale definitions and charmaps
+
+
+Version 2.1
+
+* Richard Henderson corrected size of struct timeval on Linux/Alpha to
+ conform to POSIX member type requirements. Symbol versions have been
+ adjusted as needed within the library, and for direct use by applications,
+ but there is potential for problems if third-party libraries use
+ struct timeval as part of their interface. This does not present
+ a problem for X and other "essential" system libraries.
+
+* An additional locale model to support C++ Standard Library locale
+ model and probably more was implemented by Ulrich Drepper.
+
+* Eric Youngdale and Ulrich Drepper implemented versioning of objects on
+ symbol level.
+
+* Miles Bader provided the `argp' function family to support hierachical
+ command line argument parsing, layered on top of getopt.
+
+* strtod accepts new hexadecimal floating-point format from ISO C 9X.
+
+* printf has two new specifiers %a and %A to print hexadecimal flaoting-point
+ numbers.
+
+* scanf recognizes the %a and %A format for scanning floating point numbers.
+
+* the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
+ information and interfaces for the available integer types.
+
+* about 130 new math functions were added to implement the ISO C9x math
+ library.
+
+* the new header <complex.h> contains definitions of the complex math
+ functions from ISO C 9X.
+
+* the new header <tgmath.h> defines generic macros to use complex or
+ real valued functions.
+
+* Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
+
+* Andreas Jaeger provided a test suite for the math library.
+
+* Mark Kettenis implemented the utmpx interface and an utmp daemon.
+
+* Ulrich Drepper added character set conversion functions (iconv).
+
+* Optimized string functions have been added.
+
+* The localedata addon is now part of glibc.
+
+* An implementation of profiling shared libraries was added by Ulrich Drepper.
+
+* Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
+ daemon for NSS (nscd).
+
+ Missing a better place here are some numbers on improvements. Under
+ Linux 2.1.125 un-tar-ing the kernel sources takes
+
+ user system wall
+
+ using local files 12.19s 6.88s 22.91s
+
+ using NIS 13.92s 8.91s 26.34s
+
+ using NIS & nscd 10.37s 7.34s 25.30s
+
+ using NIS+ 27.57s 30.37s 640.46s
+
+ using NIS+ & nscd 10.25s 7.83s 26.51s
+
+ using NIS & old nscd [1] 13.83s 8.32s 29.60s
+
+ Keep in mind that non-namelookup related operations dominate above times.
+ It was just a common complain that using NIS+ unpacking the kernel is
+ horribly slow.
+
+ [1] The old nscd implementation is not available anymore since it was
+ distributed with glibc up to version 2.0.98 and thus is now replaced.
+
+* Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
+
+* Mark Kettenis provided a Hesiod NSS module.
+
+* The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
+ and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
+
+* rcmd can now handle netgroups (Dick Streefland).
+
+* A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
+ Bambrough.
+
+* Support for the IPv6 protocol has been added to the socket API, as per the
+ latest draft standards.
+
+* Support for Linux 2.2 has been added.
+
+* Interface changes relative to the latest 2.0.x release:

+
+Version 2.0.1
+
+* fixed lots of header problems (especially Linux/GNU specific)
+
+* dynamic loader preserves all registers
+
+* Roland McGrath provided support for handling of auxiliary objects in
+ the ELF dynamic loader.
+
+* support for parallel builds is improved
+
+Version 2.0
+
+* GNU extensions are no longer declared by default. To enable them you
+ must define the macro `_GNU_SOURCE' in your program or compile with
+ `-D_GNU_SOURCE'.
+
+* The library has changed from using GNU ld symbol aliases to using weak
+ symbols where available. The ELF object file format supports weak
+ symbols; GNU ld also supports weak symbols in the a.out format. (There
+ is also now support for other GNU ld extensions in ELF. Use the
+ `--with-elf' option to configure to indicate you have ELF, and
+ `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
+ of many files which contained only symbol aliases, reducing the size of
+ the source and the compiled library; many other files were renamed to
+ less cryptic names previously occupied by the symbol alias files.
+ There is a new header file <elf.h> for programs which operate on
+ files in the ELF format.
+
+* Converted to Autoconf version 2, so `configure' has more options.
+ Run `configure --help' to see the details.
+
+* The library can now be configured to build profiling, highly-optimized
+ (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
+ `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
+ `configure' enable building these extra libraries. The shared library is
+ built by default when using both ELF and GNU ld. When shared libraries
+ are enabled, the new library `-ldl' is available for arbitrary run-time
+ loading of shared objects; its interface is defined in <dlfcn.h>. The
+ new header file <link.h> gives access to the internals of the run-time
+ dynamic linker, `ld.so'. The shell script `ldd' is similar to the
+ application of same name on other systems and it provides information
+ about dynamically linked binaries.
+
+* The C library now provides the run-time support code for profiling
+ executables compiled with `-pg'. Programs can control the profiling code
+ through the interface in <sys/gmon.h>. The `gmon.out' files written by
+ the GNU C library can be read only by GNU `gprof' (from GNU binutils);
+ the support for this file format was contributed by David Mosberger-Tang.
+
+* The math code has been replaced with a math library based on fdlibm from
+ Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
+ Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
+ functions. The math functions now reside in a separate library, so
+ programs using them will need to use `-lm' their linking commands.
+
+* John C. Bowman contributed optimized ix87 assembler inline functions.
+
+* Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
+ mechanism similar to that found in Solaris 2. This is now used for the
+ group, passwd, hosts, networks, services, protocols, rpc, ethers,
+ shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
+ file controls what services are used for each individual database. This
+ works by loading shared libraries with names specified in `nsswitch.conf',
+ so service modules can be changed or added at any time without even
+ relinking any program. Currently there are the file, db, and NIS based
+ NSS services available.
+
+* The new functions `strtoq' and `strtouq' parse integer values from
+ strings, like `strtol' and `strtoul', but they return `long long int' and
+ `unsigned long long int' values, respectively (64-bit quantities).
+
+* The new functions `strtof' and `strtold' parse floating-point values from
+ strings, like `strtod', but they return `float' and `long double' values,
+ respectively (on some machines `double' and `long double' are the same).
+
+* Ulrich Drepper has contributed new implementations of the floating-point
+ printing and reading code used in the `printf' family of functions and
+ `strtod', `strtof', and `strtold'. These new functions are perfectly
+ accurate, and much faster than the old ones.
+
+* The implementation of the POSIX locale model was completely rewritten by
+ Ulrich Drepper. This includes the new programs `localedef' and `locale'
+ to compile the POSIX locale definition.
+
+* The former dummy implementations of the strcoll and strxfrm function are
+ now replaced by fully functional code contributed by Ulrich Drepper. The
+ collation information comes from the POSIX locale definitions.
+
+* The new header <langinfo.h> defines an interface for accessing
+ various locale-dependent data (using the locale chosen with `setlocale').
+
+* Ulrich Drepper has contributed a new suite of functions for operation on
+ wide-character and multibyte-character strings, in <wchar.h>;
+ and classification and case conversion of wide characters, in <wctype.h>.
+ These new functions are conforming to the ISO C, Amendement 1 specification.
+
+* There is now a second implementation of the standard I/O library available.
+ It comes from GNU libg++ as was written by Per Bothner, heavily modified
+ by Hongjiu Lu and made thread safe by Ulrich Drepper.
+
+* You can now use positional parameter specifications in format strings
+ for the `printf' and `scanf' families of functions. For example,
+ `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
+ ``Number 6, Mr Jones''. This is mainly useful when providing different
+ format strings for different languages, whose grammars may dictate
+ different orderings of the values being printed. To support this
+ feature, the interface for `register_printf_handler' has changed; see
+ the header file <printf.h> for details.
+
+* The `printf' and `scanf' families of functions now understand a new
+ formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
+ to group numbers as indicated by the locale; for `scanf' and friends, this
+ says to accept as valid only a number with all the proper grouping
+ separators in the right places. In the default "C" locale, numbers are
+ not grouped; but locales for specific countries will define the usual
+ conventions (i.e. separate thousands with `,' in the US locale).
+
+* The pgrp functions have been regularized, slightly incompatibly but much
+ less confusingly. The core functions are now `getpgid' and `setpgid',
+ which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
+ argument) and BSD `setpgrp' (identical to `setpgid') functions are
+ provided for compatibility. There is no longer an incompatible `getpgrp'
+ with an argument declared under _BSD_SOURCE; no BSD code uses it.
+
+* The new header file <fts.h> and suite of functions simplify programs that
+ operate on directory trees. This code comes from 4.4 BSD.
+
+* The resolver code has been updated from the BIND 4.9.5-P1 release.
+ Parts of the code were heavily modified by Ulrich Drepper to fit in the
+ NSS scheme used in glibc.
+
+* There is a new malloc debugging hook `__memalign_hook'.
+
+* There are new typedefs `ushort' for `unsigned short int' and `uint' for
+ `unsigned int' in <sys/types.h>. These are for compatibility only and
+ their use is discouraged.
+
+* The `-lmcheck' library to enable standard malloc debugging hooks is now
+ done differently, so that it works even without GNU ld.
+
+* New function `euidaccess' checks allowed access to a file like `access',
+ but using the effective IDs instead of the real IDs.
+
+* The time zone data files have been updated for the latest and greatest
+ local time conventions of the countries of the world.
+
+* The new function `dirfd' extracts the file descriptor used by a DIR stream;
+ see <dirent.h>.
+
+* The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
+ for formatting floating-point numbers. They are provided only for
+ compatibility; new programs should use `sprintf' instead. There are
+ also equivalent function for the `long double' floating-point type and
+ all functions also exist in a reentrant form.
+
+* The new auxiliary library `-lutil' from 4.4 BSD contains various
+ functions for maintaining the login-record files (primarily of use to
+ system programs such as `login'), and convenient functions for
+ allocating and initializing a pseudo-terminal (pty) device.
+
+* Ulrich Drepper has contributed new support for System V style
+ shared memory and IPC on systems that support it.
+
+* Ulrich Drepper has contributed several miscellaneous new functions found
+ in System V: The `hsearch' family of functions provide an effective
+ implementation of hash tables; `a64l' and `l64a' provide a very simple
+ binary to ASCII mapping; `drand48' and friends provide a 48-bit random
+ number generator.
+
+* Ulrich Drepper has contributed new reentrant counterparts for the
+ `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
+
+* Ulrich Drepper has contributed new, highly-optimized versions of several
+ string functions for the i486/Pentium family of processors.
+
+* Ulrich Drepper has updated the Linux-specific code, based largely
+ on work done in Hongjiu Lu's version of GNU libc for Linux.
+ The GNU library now supports Linux versions 2.0.10 and later,
+ using the ELF object file format (i[3456]86-*-linux).
+
+* Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
+
+* David Mosberger-Tang and Richard Henderson have ported the C library
+ to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
+ dynamic linking support for ELF/Alpha.
+
+* Richard Henderson contributed several Alpha optimized assembler function
+ for arithmetic and string handling.
+
+* Ulrich Drepper has contributed a new set of message catalog functions to
+ support multiple languages using the <libintl.h> interface, for use with
+ his new package GNU gettext. Translation volunteers have contributed
+ catalogs of the library's messages in Spanish, German, and Korean.
+
+* For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
+ program and the `catgets' function for reading the catalog files it
+ creates. (The <libintl.h> interface is preferred; we include the
+ <nl_types.h> interface using `catgets' only for source compatibility with
+ programs already written to use it.)
+
+* New header file <values.h> gives SVID-compatible names for <limits.h>
+ constants.
+
+* Various new macros, declarations, and small header files for compatibility
+ with 4.4 BSD.
+
+* New function `group_member' is a convenient way to check if a process has
+ a given effective group ID.
+
+* When using GCC 2.7 and later, the socket functions are now declared in a
+ special way so that passing an argument of type `struct sockaddr_in *',
+ `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
+ `struct sockaddr *' type, does not generate a type-clash warning.
+
+* New function `error' declared in header file <error.h> is a convenient
+ function for printing error messages and optionally exiting; this is the
+ canonical function used in GNU programs. The new functions `err', `warn',
+ and friends in header file <err.h> are the canonical 4.4 BSD interface for
+ doing the same thing.
+
+* The <glob.h> interface has several new flags from 4.4 BSD that extend the
+ POSIX.2 `glob' function to do ~ and {...} expansion.
+
+* New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
+ `clearenv' which is used in POSIX.9 is also available.
+
+* New function `getsid' returns session ID number on systems that support it.
+
+* We have incorporated the 4.4 BSD `db' library (version 1.85). New header
+ files <db.h> and <mpool.h> provide a rich set of functions for several
+ types of simple databases stored in memory and in files, and <ndbm.h> is
+ an old `ndbm'-compatible interface using the `db' functions. Link with
+ `-ldb' to get these functions.
+
+* New macro `strdupa' copies a string like `strdup', but uses local stack
+ space from `alloca' instead of dynamic heap space from `malloc'.
+
+* New function `strnlen' is like `strlen' but searches only a given maximum
+ number of characters for the null terminator. `stpncpy', `strndup' and
+ `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
+ function.
+
+* New function `statfs' in header <sys/statfs.h>.
+
+* The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
+ provide convenient functions for operating on blocks of null-terminated
+ strings.
+
+* A new suite of functions in <utmp.h> handle all the details of reading
+ and writing the utmp file.
+
+* An implementation of the NIS/YP(tm) based NSS service was contributed by
+ Thorsten Kukuk.
+
+* Paul Eggert and Ulrich Drepper modified the `strftime' function to be
+ completely POSIX compliant and also implemented the extended functionality
+ to handle alternate digit representation and alternate era date formats.
+
+* Ulrich Drepper provided an implementation of the `strptime' function
+ defined in XPG4.2 which transforms a string into a `struct tm' value.
+
+* Paul Eggert provided the tzselect shell script as part of the timezone
+ code. The shell script makes it easy to select the correct timezone
+ specification.
+
+* The implementation of the malloc family of functions is completely replaced
+ by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
+ The implementation uses the mmap function (if available) and it is
+ optimized for the use in multi threaded programs.
+
+* Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
+ functions. This new functionality is usable by specifying a special
+ salt string and it is compatible with implementation on *BSD systems.
+
+* Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
+ `getsubopt' to handle second level command line options, `bsd_signal'
+ to access BSD style `signal' functionality, the obsolete `regexp' style
+ expression matcher.
+
+* the `lchown' function is available on system which support this
+ functionality.
+
+* The implementation of the shadow password handling function was contributed
+ by Ulrich Drepper.
+
+* David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
+
+* POSIX.1g support was added. The <sys/select.h> header is available,
+ `isfdtype' and `pselect' are implemented. Craig Metz contributed an
+ implementation of `getaddrinfo'.
+
+Version 1.09
+
+* For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
+
+* New header file <fstab.h> and new functions `getfsspec', `getfsent' and
+ friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
+
+* The new function `daemon' from 4.4 BSD is useful for server programs that
+ want to put themselves in the background.
+
+* Joel Sherrill has contributed support for several standalone boards that
+ run without an operating system.
+
+* `printf', `scanf' and friends now accept a `q' type modifier for long
+ long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
+
+* All of the code taken from BSD (notably most of the math and networking
+ routines) has been updated from the BSD 4.4-Lite release.
+
+* The resolver code has been updated from the BIND-4.9.3-BETA9 release.
+
+* The new functions `getdomainname' and `setdomainname' fetch or change the
+ YP/NIS domain name. These are system calls which exist on systems which
+ have YP (aka NIS).
+
+* The time zone data files have been updated for the latest international
+ conventions.
+
+* The SunRPC programs `portmap' and `rpcinfo' are now installed in
+ $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
+
+Version 1.08
+
+* The C library now includes support for Sun RPC, from Sun's free
+ RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
+ are included. (There is still no support for YP.)
+
+* Tom Quinn has contributed a port of the C library to SGI machines running
+ Irix 4 (mips-sgi-irix4).
+
+* The new `lockf' function is a simplified interface to the locking
+ facilities of `fcntl', included for compatibility.
+
+* New time functions `timegm', `timelocal', and `dysize' for compatibility.
+
+* New header file <sys/timeb.h> and new function `ftime' for compatibility.
+
+* New header files <poll.h> and <sys/poll.h> and new function `poll' for
+ compatibility.
+
+* The error message printed by `assert' for a failed assertion now includes
+ the name of the program (if using GNU ld) and the name of the calling
+ function (with versions of GCC that support this).
+
+* The `psignal' function is now declared in <signal.h>, not <stdio.h>.
+
+* The library now includes the <sys/mman.h> header file and memory
+ management functions `mmap', `munmap', `mprotect', `msync', and
+ `madvise', on systems that support those facilities.
+
+* The interface for `mcheck' has changed slightly: the function called to
+ abort the program when an allocation inconsistency is detected now takes
+ an argument that indicates the type of failure. The new function
+ `mprobe' lets you request a consistency check for a particular block at
+ any time (checks are normally done only when you call `free' or `realloc'
+ on a block).
+
+* It is now possible to easily cross-compile the C library, building on one
+ system a library to run on another machine and/or operating system. All
+ you need to do is set the variable `HOST_CC' in `configparms' to the
+ native compiler for programs to run on the machine you are building on (a
+ few generator programs are used on Unix systems); set `CC' to the
+ cross-compiler.
+
+* The new function `fexecve' (only implemented on the GNU system) executes
+ a program file given a file descriptor already open on the file.
+
+Version 1.07
+
+* Brendan Kehoe has contributed most of a port to the DEC Alpha
+ running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
+
+* You can set the variable `libprefix' in `configparms' to specify a prefix
+ to be prepended to installed library files; this makes it easy to install
+ the GNU C library to be linked as `-lgnuc' or whatever.
+
+* The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
+ copies a limited number of characters from a string, and returns the
+ address of the last character written.
+
+* You no longer need to check for whether the installed `stddef.h' is
+ compatible with the GNU C library. configure now checks for you.
+
+* You can now define a per-stream `fileno' function to convert the
+ stream's cookie into an integral file descriptor.
+
+* ``malloc (0)'' no longer returns a null pointer. Instead, it
+ allocates zero bytes of storage, and returns a unique pointer which
+ you can pass to `realloc' or `free'. The behavior is undefined if
+ you dereference this pointer.
+
+* The C library now runs on Sony NEWS m68k machines running either
+ NewsOS 3 or NewsOS 4.
+
+* The new `syscall' function is a system-dependent primitive function
+ for invoking system calls. It has the canonical behavior on Unix
+ systems, including unreliable return values for some calls (such as
+ `pipe', `fork' and `getppid').
+
+* The error code `EWOULDBLOCK' is now obsolete; it is always defined
+ to `EAGAIN', which is the preferred name. On systems whose kernels
+ use two distinct codes, the C library now translates EWOULDBLOCK to
+ EAGAIN in every system call function.
+
+Version 1.06
+
+* The GNU C Library Reference Manual is now distributed with the library.
+ `make dvi' will produce a DVI file of the printed manual.
+ `make info' will produce Info files that you can read on line using C-h i
+ in Emacs or the `info' program.
+ Please send comments on the manual to bug-glibc-manual@gnu.org.
+
+* The library now supports SVR4 on i386s (i386-unknown-sysv4).
+
+* Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
+
+* Jason Merrill has contributed a port to the Sequent Symmetry running
+ Dynix version 3 (i386-sequent-dynix).
+
+* The library has been ported to i386s running SCO 3.2.4 (also known as SCO
+ ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
+
+* New function `memory_warnings' lets you arrange to get warnings when
+ malloc is running out of memory to allocate, like Emacs gives you.
+
+* The C library now contains the relocating allocator used in Emacs 19 for
+ its editing buffers. This allocator (ralloc) minimizes allocation
+ overhead and fragmentation by moving allocated regions around whenever it
+ needs to. You always refer to a ralloc'd region with a "handle" (a
+ pointer to a pointer--an object of type `void **').
+
+* There is a new `printf' format: `%m' gives you the string corresponding
+ to the error code in `errno'.
+
+* In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
+ or `%[' conversion, but instead of filling in a fixed-sized buffer you
+ pass, the `a' modifier says to fill in a `char **' you pass with a
+ malloc'd string.
+
+* The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
+ `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
+ name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
+
+* `mkstemp' is a traditional Unix function to atomically create and open a
+ uniquely-named temporary file.
+
+Version 1.05
+
+* The standard location for the file that says what the local timezone is
+ has changed again. It is now `/usr/local/etc/localtime' (or more
+ precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
+
+* The distribution no longer contains any files with names longer than 14
+ characters.
+
+* `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
+ These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
+
+* New functions `ttyslot' and `syslog' from 4.4 BSD.
+
+Version 1.04
+
+* The configuration process has changed quite a bit. The `configure'
+ script is now used just like the configuration scripts for other GNU
+ packages. The `sysdeps' directory hierarchy is much rearranged.
+ The file `INSTALL' explains the new scheme in detail.
+
+* The header files no longer need to be processed into ANSI C and
+ traditional C versions. There is just one set of files to install, and
+ it will work with ANSI or old C compilers (including `gcc -traditional').
+
+* Brendan Kehoe and Ian Lance Taylor have ported the library to the
+ MIPS DECStation running Ultrix 4.
+
+* The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
+ Tom Quinn contributed the initial code. The GNU C library can NOT yet be
+ made itself into a shared library.
+
+* Yet further improved support for the i386, running 4.3 BSD-like systems
+ (such as Mach 3 with the Unix single-server), or System V.
+
+* New function `strncasecmp' to do case-insensitive string comparison
+ with limited length.
+
+* New function `strsep' is a reentrant alternative to `strtok'.
+
+* New functions `scandir' and `alphasort' for searching directories.
+
+* New function `setenv' is a better interface to `putenv'.
+
+* Ian Lance Taylor has contributed an implementation of the SVID `ftw'
+ function for traversing a directory tree.
+
+* The GNU obstack package is now also part of the C library.
+ The new function `open_obstack_stream' creates a stdio stream that
+ writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
+ formatted output directly to an obstack.
+
+* Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
+ cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
+
+* `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
+
+* The new functions `strfry' and `memfrob' do mysterious and wonderful
+ things to your strings.
+
+* There are some new test programs: test-fseek, testmb, and testrand.
+
+* Some work has been done to begin porting the library to 4.4 BSD and Linux.
+ These ports are not finished, but are a good starting place for really
+ supporting those systems.
+
+* `/etc/localtime' is now the standard location for the file that says what
+ the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
+ This follows the general principle that `/etc' is the place for all local
+ configuration files.
+
+* The C library header files now use `extern "C"' when used by the C++
+ compiler, so the C library should now work with C++ code.
+
+* The header file <bstring.h> is gone. <string.h> now declares bcopy,
+ bcmp, bzero, and ffs. (Update: nowadays these functions are declared
+ in <strings.h>.)
+
+* Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
+ function which uses the `merge sort' algorithm, and is said to be
+ significantly faster than the old GNU `qsort' function. Merge sort is
+ now the standard `qsort' function. The new algorithm can require a lot
+ of temporary storage; so, the old sorting function is called when the
+ required storage is not available.
+
+* The C library now includes Michael Glad's Ultra Fast Crypt, which
+ provides the Unix `crypt' function, plus some other entry points.
+
+* The code and header files taken from 4.4 BSD have been updated with the
+ latest files released from Berkeley.

+/* Notes on implementation:
+
+ Thread Local Store (TLS)
+
+ Overview:
+
+ The implementation currently supports both traditional TLS and TLS
+ descriptors, but only general dynamic (GD).
+
+ For traditional TLS the assembler will present us with code
+ fragments of the form:
+
+ adrp x0, :tlsgd:foo
+ R_AARCH64_TLSGD_ADR_PAGE21(foo)
+ add x0, :tlsgd_lo12:foo
+ R_AARCH64_TLSGD_ADD_LO12_NC(foo)
+ bl __tls_get_addr
+ nop
+
+ For TLS descriptors the assembler will present us with code
+ fragments of the form:
+
+ adrp x0, :tlsdesc:foo R_AARCH64_TLSDESC_ADR_PAGE21(foo)
+ ldr x1, [x0, #:tlsdesc_lo12:foo] R_AARCH64_TLSDESC_LD64_LO12(foo)
+ add x0, x0, #:tlsdesc_lo12:foo R_AARCH64_TLSDESC_ADD_LO12(foo)
+ .tlsdesccall foo
+ blr x1 R_AARCH64_TLSDESC_CALL(foo)
+
+ The relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} against foo
+ indicate that foo is thread local and should be accessed via the
+ traditional TLS mechanims.
+
+ The relocations R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC}
+ against foo indicate that 'foo' is thread local and should be accessed
+ via a TLS descriptor mechanism.
+
+ The precise instruction sequence is only relevant from the
+ perspective of linker relaxation which is currently not implemented.
+
+ The static linker must detect that 'foo' is a TLS object and
+ allocate a double GOT entry. The GOT entry must be created for both
+ global and local TLS symbols. Note that this is different to none
+ TLS local objects which do not need a GOT entry.
+
+ In the traditional TLS mechanism, the double GOT entry is used to
+ provide the tls_index structure, containing module and offset
+ entries. The static linker places the relocation R_AARCH64_TLS_DTPMOD
+ on the module entry. The loader will subsequently fixup this
+ relocation with the module identity.
+
+ For global traditional TLS symbols the static linker places an
+ R_AARCH64_TLS_DTPREL relocation on the offset entry. The loader
+ will subsequently fixup the offset. For local TLS symbols the static
+ linker fixes up offset.
+
+ In the TLS descriptor mechanism the double GOT entry is used to
+ provide the descriptor. The static linker places the relocation
+ R_AARCH64_TLSDESC on the first GOT slot. The loader will
+ subsequently fix this up.
+
+ Implementation:
+
+ The handling of TLS symbols is implemented across a number of
+ different backend functions. The following is a top level view of
+ what processing is performed where.
+
+ The TLS implementation maintains state information for each TLS
+ symbol. The state information for local and global symbols is kept
+ in different places. Global symbols use generic BFD structures while
+ local symbols use backend specific structures that are allocated and
+ maintained entirely by the backend.
+
+ The flow:
+
+ elfNN_aarch64_check_relocs()
+
+ This function is invoked for each relocation.
+
+ The TLS relocations R_AARCH64_TLSGD_{ADR_PREL21,ADD_LO12_NC} and
+ R_AARCH64_TLSDESC_{ADR_PAGE21,LD64_LO12_NC,ADD_LO12_NC} are
+ spotted. One time creation of local symbol data structures are
+ created when the first local symbol is seen.
+
+ The reference count for a symbol is incremented. The GOT type for
+ each symbol is marked as general dynamic.
+
+ elfNN_aarch64_allocate_dynrelocs ()
+
+ For each global with positive reference count we allocate a double
+ GOT slot. For a traditional TLS symbol we allocate space for two
+ relocation entries on the GOT, for a TLS descriptor symbol we
+ allocate space for one relocation on the slot. Record the GOT offset
+ for this symbol.
+
+ elfNN_aarch64_size_dynamic_sections ()
+
+ Iterate all input BFDS, look for in the local symbol data structure
+ constructed earlier for local TLS symbols and allocate them double
+ GOT slots along with space for a single GOT relocation. Update the
+ local symbol structure to record the GOT offset allocated.
+
+ elfNN_aarch64_relocate_section ()
+
+ Calls elfNN_aarch64_final_link_relocate ()
+
+ Emit the relevant TLS relocations against the GOT for each TLS
+ symbol. For local TLS symbols emit the GOT offset directly. The GOT
+ relocations are emitted once the first time a TLS symbol is
+ encountered. The implementation uses the LSB of the GOT offset to
+ flag that the relevant GOT relocations for a symbol have been
+ emitted. All of the TLS code that uses the GOT offset needs to take
+ care to mask out this flag bit before using the offset.
+
+ elfNN_aarch64_final_link_relocate ()
+
+ Fixup the R_AARCH64_TLSGD_{ADR_PREL21, ADD_LO12_NC} relocations. */
