+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)

+Version 2.24
+
+* 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

+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 create and
+ trigger this bug. Affected applications typically create and
destroy threads frequently. (Bug 19048 was reported and analyzed by
Ericsson.)
tzselect). This is useful for people who build the timezone data and code
independent of the GNU C Library.
-* The LD_POINTER_GUARD environment variable can no longer be used to
- disable the pointer guard feature. It is always enabled.
-
* 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)
