Lu from Intel. -+ -+* Optimized x86-64 trunc and truncf for processors with SSE4.1. -+ -+* Optimized generic expf, exp2f, logf, log2f and powf. -+ -+* 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, 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. -+ -+Deprecated and removed features, and other changes affecting compatibility: -+ -+* 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. -+ -+Changes to build and runtime requirements: -+ -+ [Add changes to build and runtime requirements here] -+ -+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). -+ -+The following bugs are resolved with this release: -+ -+ [The release manager will add the list generated by -+ scripts/list-fixed-bugs.py just before the release.] -+ -+ -+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). -+ -+The following bugs are resolved

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. -+>>>>>>> c369d66e54...
