34 16453, 16474, 16506, 16510, 16529
36 * Slovenian translations for glibc messages have been contributed by the
37 Translation Project's Slovenian team of translators.
39 * The public headers no longer use __unused nor __block. This change is to
40 support compiling programs that are derived from BSD sources and use
41 __unused internally, and to support compiling with Clang's -fblock
42 extension which uses __block.
44 * CVE-2012-4412 The strcoll implementation caches indices and rules for
45 large collation sequences to optimize multiple passes. This cache
46 computation may overflow for large collation sequences and may cause a
47 stack or buffer overflow. This is now fixed to use a slower algorithm
48 which does not use a cache if there is an integer overflow.
50 * CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
51 rules for large collation sequences to optimize multiple passes and falls
52 back to alloca if malloc fails, resulting in a possible stack overflow.
53 The implementation now falls back to an uncached collation sequence lookup
56 * CVE-2013-4788 The pointer guard used for pointer mangling was not
57 initialized for static applications resulting in the security feature
58 being disabled. The pointer guard is now correctly initialized to a
59 random value for static applications. Existing static applications need
60 to be recompiled to take advantage of the fix (bug 15754).
62 * CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
63 to the d_name member of struct dirent, or omit the terminating NUL
64 character. (Bugzilla #14699).
66 * CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
67 aligned_alloc functions could allocate too few bytes or corrupt the
68 heap when passed very large allocation size values (Bugzilla #15855,
71 * CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
72 for AF_INET6 has been fixed (Bugzilla #16072).
74 * New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
75 pap_CW, quz_PE, the_NP.
77 * Substantially revised locales: gd_GB, ht_HT
79 * The LC_ADDRESS field was updated to support country_car for almost all
82 * ISO 1427 definitions were updated.
84 * ISO 3166 definitions were updated.
86 * The localedef utility now supports --big-endian and --little-endian
87 command-line options to generate locales for a different system from that
88 for which the C library was built.
90 * Binary locale files now only depend on the endianness of the system for
91 which they are generated and not on other properties of that system. As a
92 consequence, binary files generated with new localedef may be incompatible
93 with old versions of the GNU C Library, and binary files generated with
94 old localedef may be incompatible with this version of the GNU C Library,
95 in the following circumstances:
97 + Locale files may be incompatible on m68k systems.
99 + Locale archive files (but not separate files for individual locales) may
100 be incompatible on systems where plain "char" is signed.
102 * The configure option --disable-versioning has been removed. Builds with
103 --disable-versioning had not worked for several years.
105 * ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
106 cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
108 * SystemTap probes for malloc have been introduced.
110 * SystemTap probes for slow multiple precision fallback paths of
111 transcendental functions have been introduced.
113 * Support for powerpc64le has been added.
115 * The soft-float powerpc port now supports e500 processors.
117 * Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
119 * A new feature test macro _DEFAULT_SOURCE is available to enable the same
120 set of header declarations that are enabled by default, even when other
121 feature test macros or compiler options such as -std=c99 would otherwise
122 disable some of those declarations.
124 * The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
125 conflict with POSIX. The libbsd-compat library (which was a dummy library
126 that did nothing) has also been removed.
128 * Preliminary documentation about Multi-Thread, Async-Signal and
129 Async-Cancel Safety has been added.
133 * The following bugs are resolved with this release:
135 2546, 2560, 5159, 6809, 7006, 10060, 10062, 10283, 10357, 10686, 11120,
136 11561, 12310, 12387, 12492, 12515, 12723, 13550, 13889, 13951, 13988,
137 14142, 14176, 14200, 14256, 14280, 14293, 14317, 14327, 14478, 14496,
138 14582, 14686, 14812, 14888, 14894, 14907, 14908, 14909, 14920, 14952,
139 14964, 14981, 14982, 14985, 14991, 14994, 14996, 15000, 15003, 15006,
140 15007, 15014, 15020, 15022, 15023, 15036, 15054, 15055, 15062, 15078,
141 15084, 15085, 15086, 15100, 15160, 15214, 15221, 15232, 15234, 15283,
142 15285, 15287, 15304, 15305, 15307, 15309, 15327, 15330, 15335, 15336,
143 15337, 15339, 15342, 15346, 15359, 15361, 15366, 15380, 15381, 15394,
144 15395, 15405, 15406, 15409, 15416, 15418, 15419, 15423, 15424, 15426,
145 15429, 15431, 15432, 15441, 15442, 15448, 15465, 15480, 15485, 15488,
146 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583,
147 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674, 15711, 15755,
150 * CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
151 has been fixed by disabling the use of pt_chown (Bugzilla #15755).
152 Distributions can re-enable building and using pt_chown via the new configure
153 option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
154 considerable security risks and should only be used if the distribution
155 understands and accepts the risks.
157 * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
160 * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
161 fixed (Bugzilla #15330).
163 * Add support for calling C++11 thread_local object destructors on thread
164 and program exit. This needs compiler support for offloading C++11
165 destructor calls to glibc.
167 * Improved worst case performance of libm functions with double inputs and
170 * Support for priority inherited mutexes in pthread condition variables on
171 non-x86 architectures.
173 * Port to Xilinx MicroBlaze contributed by David Holsgrove.
175 * Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
177 * Optimized string functions for ARM. Implemented by Will Newton and
180 * Optimized libm functions for SPARC. Implemented by David S. Miller.
182 * Support for building more of ARM glibc as Thumb-2 code. Implemented by
185 * Support for building most of MIPS glibc as MIPS16 code. Implemented by
186 Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
188 * Added a benchmark framework to track performance of functions in glibc.
190 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
191 It is based on draft TS 18661 and currently enabled as a GNU extension.
193 * On Linux, the clock function now uses the clock_gettime system call
194 for improved precision, rather than old times system call.
196 * Added support for version-3 tz format files. This is needed when using
197 the tz database release 2013e or later, and affects a few unusual cases --
198 currently only TZ='America/Godthab' for time stamps after 2037.
200 * Added new API functions pthread_getattr_default_np and
201 pthread_setattr_default_np to get and set the default pthread
202 attributes of a process.
204 * Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
205 This may improve lock scaling of existing programs on TSX capable systems.
206 When the --enable-lock-elision=yes parameter is specified at configure
207 time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
210 * Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
211 availability). Implemented by Ryan S. Arnold.
213 * Support added for POWER8 platform. Implemented by Ryan S. Arnold.
217 * The following bugs are resolved with this release:
219 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808,
220 9685, 9914, 10014, 10038, 10114, 10191, 10631, 10873, 11438, 11607, 11638,
221 11741, 12140, 13013, 13412, 13542, 13601, 13603, 13604, 13629, 13679,
222 13696, 13698, 13717, 13741, 13759, 13761, 13763, 13881, 13939, 13950,
223 13952, 13966, 14042, 14047, 14090, 14150, 14151, 14152, 14154, 14157,
224 14166, 14173, 14195, 14197, 14237, 14246, 14251, 14252, 14283, 14298,
225 14303, 14307, 14328, 14331, 14336, 14337, 14347, 14349, 14368, 14376,
226 14417, 14447, 14459, 14476, 14477, 14501, 14505, 14510, 14516, 14518,
227 14519, 14530, 14532, 14538, 14543, 14544, 14545, 14557, 14562, 14568,
228 14576, 14579, 14583, 14587, 14595, 14602, 14610, 14621, 14638, 14645,
229 14648, 14652, 14660, 14661, 14669, 14672, 14683, 14694, 14716, 14719,
230 14743, 14767, 14783, 14784, 14785, 14793, 14796, 14797, 14801, 14803,
231 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833,
232 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872,
233 14879, 14889, 14893, 14898, 14914.
235 * Optimization of memcpy for MIPS.
237 * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
238 EMFILE has been fixed (Bugzilla #14889).
240 * The add-on ports collection is now distributed in the "ports" subdirectory
241 of the main GNU C Library distribution, rather than separately.
243 * Port to ARM AArch64 contributed by Linaro.
245 * Support for STT_GNU_IFUNC symbols added for s390 and s390x.
246 Optimized versions of memcpy, memset, and memcmp added for System z10 and
248 Implemented by Andreas Krebbel.
250 * The new function secure_getenv allows secure access to the environment,
251 returning NULL if running in a SUID/SGID process. This function replaces
252 the internal function __secure_getenv.
254 * SystemTap static probes have been added into the dynamic linker.
255 Implemented by Gary Benson.
257 * Optimizations of string functions strstr, strcasestr and memmem.
258 Implemented by Maxim Kuvyrkov.
260 * The minimum Linux kernel version that this version of the GNU C Library
261 can be used with is 2.6.16.
263 * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
264 powerpc POWER7. Implemented by Will Schmidt.
266 * New configure option --disable-nscd builds the C library such that it
267 never attempts to contact the Name Service Caching Daemon (nscd).
268 New configure option --disable-build-nscd avoids building nscd itself;
269 this is the default if --disable-nscd is used.
271 * Improved support for cross-compilation, including cross-testing and
272 bootstrap builds without a previously built glibc.
274 * Several testsuite tests are now able to test multiple IFUNC variants of an
275 interface, rather than just testing the one that would be chooen by
278 * New configure options --with-bugurl and --with-pkgversion, for
279 distributors to use to embed their bug-reporting and package version
280 information in --help and --version output.
282 * The ttyname and ttyname_r functions on Linux now fall back to searching for
283 the tty file descriptor in /dev/pts or /dev if /proc is not available. This
284 allows creation of chroots without the procfs mounted on /proc.
286 * The `crypt' function now fails if passed salt bytes that violate the
287 specification for those values. On Linux, the `crypt' function will
288 consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
289 enabled, and fail on encrypted strings using the MD5 or DES algorithm
290 when the mode is enabled.
292 * The `clock_*' suite of functions (declared in <time.h>) is now available
293 directly in the main C library. Previously it was necessary to link with
294 -lrt to use these functions. This change has the effect that a
295 single-threaded program that uses a function such as `clock_gettime' (and
296 is not linked with -lrt) will no longer implicitly load the pthreads
297 library at runtime and so will not suffer the overheads associated with
298 multi-thread support in other code such as the C++ runtime library.
300 * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
305 * The following bugs are resolved with this release:
307 174, 208, 350, 369, 411, 706, 766, 887, 2074, 2541, 2547, 2548, 2550,

331 * Support for the x32 ABI on x86-64 added. The x32 target is selected by
332 configuring glibc with:
333 BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
334 Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
335 Implemented by H.J. Lu.
339 + define static_assert
341 + do not declare gets
343 + declare at_quick_exit and quick_exit also for ISO C11
345 + aligned_alloc. NB: The code is deliberately allows the size parameter
346 to not be a multiple of the alignment. This is a moronic requirement
347 in the standard but it is only a requirement on the caller, not the
352 + uchar.h support added
354 + CMPLX, CMPLXF, CMPLXL added
356 Implemented by Ulrich Drepper.
358 * Support for the IA-64 has been moved to ports.
360 * Remove support for anything but ELF binary format
362 * Checking versions of poll, ppoll added.
363 Implemented by Ulrich Drepper.
365 * More generic and 64-bit performance optimizations to math functions.
366 Implemented by Ulrich Drepper.
368 * New configure option --enable-obsolete-rpc makes the deprecated RPC
369 headers and functions available at compile time as they were before
370 version 2.14. This option will be removed at some time in the future
371 after the TI-RPC library becomes fully sufficient for the needs of
372 existing applications.
374 * Compatibility code for Linux kernel versions before 2.4 has been removed.
375 Note that glibc is not expected to work with any Linux kernel version
378 * New header <sys/auxv.h> and function getauxval allowing easy access to
379 the AT_* key-value pairs passed from the Linux kernel. The header also
380 defines the HWCAP_* bits associated with the AT_HWCAP key.
382 * New locales: mag_IN
384 * New configure option --enable-systemtap builds SystemTap static probes
385 into libc for setjmp and longjmp and into libpthread for various operations.
386 So far the setjmp/longjmp probes and some of the libpthread probes are
387 provided only for i*86 and x86_64.
388 Implemented by Roland McGrath and Rayson Ho.
390 * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
392 * More optimized functions for PowerPC. Implemented by Adhemerval Zanella
395 * More optimized functions for SPARC. Implemented by David S. Miller.
397 * Improved support for cross-compilation, especially bootstrap builds
398 without a previously built glibc.
400 * Ports for the TILE-Gx and TILEPro families of processors. Contributed by
401 Chris Metcalf from Tilera.
403 * Support for the old ARM ABI has been removed from ports. Only the EABI is
404 now supported for ARM processors.
406 * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
407 as the name of the dynamic linker, to distinguish it from the
408 /lib/ld-linux.so.3 dynamic linker used for the base EABI.
410 * Support for CRIS has been removed from ports.
412 * A new class of installed header has been documented for low-level
413 platform-specific functionality. PowerPC added the first instance with a
414 function to provide time base register access. Contributed by Tulio
415 Magno Quites Machado Filho.
417 * ix86 configurations now install header files that are consistent with
418 what x86-64 configurations install. These same header files can be used
419 for -m32, -m64, or -mx32 builds.
420 Contributed by H.J. Lu.
422 * Math library bug fixes. A thorough audit of all open math library bugs was
423 conducted by Joseph Myers. Significant progress was made on many math
424 library bugs resulting in more accurate exceptions and function results.
425 Many thanks to all those that contributed including Andreas Jaeger for his
426 patch review and work on the x87 trigonometric instruction issues.
428 * Timezone data is no longer installed. Timezone-related binaries and scripts
429 will continue to be installed. Users should obtain their timezone data from
430 their distribution provider or from the tzdata package at
431 <ftp://munnari.oz.au/pub/>.
435 * The following bugs are resolved with this release:
437 6779, 6783, 9696, 10103, 10709, 11589, 11929, 12403, 12786, 12840, 12847,

445 * New program pldd to list loaded object of a process
446 Implemented by Ulrich Drepper.
448 * Add nss_db support back to glibc. No more dependency on Berkeley db
449 and support for initgroups lookups.
450 Implemented by Ulrich Drepper.
452 * Optimized strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-32.
453 Contributed by HJ Lu.

473 Implemented by Ulrich Drepper.
475 * nscd now also caches the netgroup database.
476 Implemented by Ulrich Drepper.
478 * Integrate libm with gcc's -ffinite-math-only option.
479 Implemented by Ulrich Drepper.
481 * Lots of generic, 64-bit, and x86-64-specific performance optimizations
482 to math functions. Implemented by Ulrich Drepper.
484 * Optimized strcasecmp and strncasecmp for AVX on x86-64.
485 Implemented by Ulrich Drepper.
487 * New Linux interfaces: process_vm_readv, process_vm_writev

495 * New locales: bho_IN, unm_US, es_CU, ta_LK
499 * The following bugs are resolved with this release:
501 386, 6420, 7101, 9730, 9732, 9809, 10138, 10149, 10157, 11099, 11257,

510 12795, 12811, 12813, 12814, 12841
512 * The RPC implementation in libc is obsoleted. Old programs keep working
513 but new programs cannot be linked with the routines in libc anymore.
514 Programs in need of RPC functionality must be linked against TI-RPC.
515 The TI-RPC implementation is IPv6 enabled and there are other benefits.
517 Visible changes of this change include (obviously) the inability to link
518 programs using RPC functions without referencing the TI-RPC library and the
519 removal of the RPC headers from the glibc headers.
520 Implemented by Ulrich Drepper.
522 * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
523 syncfs, setns, sendmmsg
525 * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
526 yue_HK, lij_IT, mhr_RU
528 * New encodings: CP770, CP771, CP772, CP773, CP774
530 * New program sotruss to trace calls through PLTs
531 Implemented by Ulrich Drepper.
533 * The malloc hook implementation is marked deprecated and will be removed
534 from the default implementation in the next version. The design never
535 worked ever since the introduction of threads. Even programs which do
536 not create threads themselves can use multiple threads created internally.
540 * The following bugs are resolved with this release:
542 3268, 6812, 7066, 10085, 10484, 10563, 10851, 11149, 11155, 11577, 11611,

548 * New Linux interfaces: prlimit, prlimit64, fanotify_init, fanotify_mark
550 * POWER7 optimizations: memset, memcmp, strncmp
552 * New optimized string functions for x86-64: strnlen (SSE2),
553 strcasecmp (SSE2, SSSE3, SSE4.2), strncasecmp (SSE2, SSSE3, SSE4.2)
554 Implemented by Ulrich Drepper.

569 * New interfaces: pthread_getname_np, pthread_setname_np
571 * New Linux interface: recvmmsg
573 * STT_GNU_IFUNC implemented for Sparc by David Miller.
575 * The dynamic linker now recognizes supported ABI versions from the
576 EI_ABIVERSION field in the ELF header.
577 Implemented by Ulrich Drepper.
579 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
580 will not be used to fill in password fields in the passwd.byname replies.
581 Instead it is used to synthesize the shadow.byname table, should it be
582 missing. This is a useful mode in some installations involving Solaris.
583 Implemented by Ulrich Drepper.
585 * New locales: kok_IN, sq_MK, cv_RU
589 * The following bugs are resolved with this release:
591 3270, 7094, 9924, 9986, 10011, 10085, 10107, 10159, 10162, 10166, 10183,

596 10789, 10817, 10823, 10840, 10847
598 * New interfaces: execvpe, pthread_sigqueue, mkstemps, mkstemps64, mkostemps,
600 Implemented by Ulrich Drepper.
602 * Checking version of longjmp added that fails if an uninitialized stack
603 frame would be created. Implemented by Ulrich Drepper.
605 * STT_GNU_IFUNC is now supported in static executables.
606 Implemented by H.J. Lu.
608 * STT_GNU_IFUNC implemented for PPC by Alan Modra.
610 * New optimized string functions for x86-64: strstr, strcasestr, memcmp,
611 strcspn, strpbrk, strspn, strcpy, stpcpy, strncpy, strcmp (SSE2, SSE4.2),
612 strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2).
613 Contributed by H.J. Lu.
615 strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3).
616 Implemented by Ulrich Drepper.
618 * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk,
620 Contributed by H.J. Lu.

623 Implemented by H.J. Lu and Ulrich Drepper.
625 * AVX support in x86-64 auditing support in ld.so.
626 Implemented by H.J. Lu.
628 * STB_GNU_UNIQUE support added.
629 Implemented by Ulrich Drepper.
631 * Implement second fallback mode for optimized DNS lookup for even more
632 broken environments. If two requests from the same port are not
633 handled correctly close the socket and open a new one before sending
634 the second request. The 'single-request-reopen' option in /etc/resolv.conf
635 can be used to select this mode right away, instead of rediscovering the
636 necessity is every process again.
637 Implemented by Ulrich Drepper.
639 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
640 Implemented by Adam Tkac.
642 * Optimized iconv conversions for S390x.
643 Implemented by Andreas Krebbel.
645 * Using condvars with PI mutexes is now more efficient due to kernel
646 support for requeueing to PI futexes. NPTL support added for x86-64.
647 Implemented by Ulrich Drepper.
649 * New locales: ps_AF, my_MM
653 * The following bugs are resolved with this release:
655 697, 5381, 5807, 6411, 6545, 7040, 7058, 7067, 7080, 7083, 7095, 7098,
656 9677, 9694, 9697, 9701, 9704, 9705, 9706, 9720, 9726, 9730, 9733, 9736,

661 * New interfaces: preadv, preadv64, pwritev, pwritev64, malloc_info
662 Implemented by Ulrich Drepper.
664 * New Linux interfaces: accept4, fallocate, fallocate64.
665 Implemented by Ulrich Drepper.
667 * Correct declarations of string function when used in C++ code. This
668 could lead to compile errors for invalid C++ code.
670 * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are
673 * New POSIX 2008 interface: psiginfo
674 Implemented by Ulrich Drepper.
676 * New ISO C++1x interfaces: quick_exit, at_quick_exit
677 Implemented by Ulrich Drepper.
679 * Support for selecting between multiple function definitions at runtime
680 using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
682 * The libcrypt library can now use the hash function implementations in
683 NSS. Implemented by Ulrich Drepper.
685 * The malloc implementation can be compiled to be less memory efficient
686 but higher performing in multi-threaded programs.
687 Implemented by Ulrich Drepper.
689 * New locales: nan_TW@latin, ks_IN
691 * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
692 Implemented by Ulrich Drepper.
694 * Extended printf hook support. It is possible to use user-defined types
695 and extend existing format specifiers.
696 Implemented by Ulrich Drepper.
698 * Handling for group shadow files has been added.
699 Implemented by Ulrich Drepper.
701 * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
702 servers (the case, e.g., for some people using the built-in DNS
703 server in ADSL modems/routers). There is a once-per-process timeout
704 in case of a broken server. To avoid it, users can run nscd or put
705 'options single-request' in /etc/resolv.conf.
706 Implemented by Ulrich Drepper.
710 * The following bugs are resolved with this release:
712 3406, 5209, 5210, 5381, 5794, 5814, 5911, 6428, 6438, 6442, 6447, 6461,

715 6845, 6856, 6857, 6860, 6867, 6875, 6919, 6920, 6942, 6947, 6955, 6966,
716 6968, 6974, 6980, 6995, 7008, 7009, 7029
718 * Unified lookup for getaddrinfo: IPv4 and IPv6 addresses are now looked
719 up at the same time. Implemented by Ulrich Drepper.
721 * TLS descriptors for LD and GD on x86 and x86-64.
722 Implemented by Alexandre Oliva.
724 * getaddrinfo now handles DCCP and UDPlite.
725 Implemented by Ulrich Drepper.
727 * New fixed-size conversion macros: htobe16, htole16, be16toh, le16toh,
728 htobe32, htole32, be32toh, le32toh, htobe64, htole64, be64toh, le64toh.
729 Implemented by Ulrich Drepper.
731 * New implementation of memmem, strstr, and strcasestr which is O(n).
732 Implemented by Eric Blake.
734 * New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2
736 * Implement "e" option for popen to open file descriptor with the
737 close-on-exec flag set. Implemented by Ulrich Drepper.
739 * Implement "b" mode for fmemopen. In this mode writes writes don't
740 implicitly add a NUL byte and seeks from the end of the buffer really
741 use the buffer end, not the string length as the basis.
742 Implemented by Ulrich Drepper.
744 * Many functions, exported and internal, now atomically set the close-on-exec
745 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
747 * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
749 Implemented by Pravin Satpute.

778 Implemented by Ulrich Drepper.
780 * More checking functions: asprintf, dprintf, obstack_printf, vasprintf,
781 vdprintf, and obstack_vprintf.
782 Implemented by Jakub Jelinek.
784 * Faster memset for x86-64.
785 Implemented by Harsha Jagasia and H.J. Lu.
787 * Faster memcpy on x86.
788 Implemented by Ulrich Drepper.
790 * ARG_MAX is not anymore constant on Linux. Use sysconf(_SC_ARG_MAX).
791 Implemented by Ulrich Drepper.
793 * Faster sqrt and sqrtf implemention for some PPC variants.
794 Implemented by Steven Munroe.
798 * The following bugs are resolved with this release:

804 5071, 5103, 5104, 5112, 5113, 5184, 5186
806 * More checking functions: fread, fread_unlocked, open*, mq_open.
807 Implemented by Jakub Jelinek and Ulrich Drepper.
809 * Extend fortification to C++. Implemented by Jakub Jelinek.
811 * Implement 'm' modifier for scanf. Add stricter C99/SUS compliance
812 by not recognizing 'a' as a modifier when those specs are requested.
813 Implemented by Jakub Jelinek.
815 * PPC optimizations to math and string functions.
816 Implemented by Steven Munroe.
818 * New interfaces: mkostemp, mkostemp64. Like mkstemp* but allow additional
819 options to be passed. Implemented by Ulrich Drepper.
821 * More CPU set manipulation functions. Implemented by Ulrich Drepper.
823 * New Linux interfaces: signalfd, eventfd, eventfd_read, and eventfd_write.

857 * New Linux interfaces: epoll_pwait, sched_getcpu.
859 * New generic interfaces: strerror_l.
861 * nscd can now cache the services database. Implemented by Ulrich Drepper.
865 * The following bugs are resolved with this release:
867 39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784,

875 3225, 3251, 3252, 3253, 3273
877 * For Linux, the sorting of addresses returned by getaddrinfo now also
878 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
879 Implemented by Ulrich Drepper.
881 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
882 Implemented by Ulrich Drepper.
884 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
886 * New iconv module for MIK. Contributed by Alexander Shopov.
888 * For sites with broken group and/or passwd database, the auto-propagate
889 option of nscd can prevent creating ID lookup entries from the results
890 of a name lookup and vice versa. This usually is no problem but some
891 site might have problems with the default behavior.
892 Implemented by Ulrich Drepper.
894 * Iterating over entire database in NIS can be slow. With the
895 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
896 to trade time for memory. The entire database will be read at once.
897 Implemented by Ulrich Drepper.
899 * The interfaces introduced in RFC 3542 have been implemented by
902 * Support for the new ELF hash table format was added by Ulrich Drepper.
904 * Support for priority inheritance mutexes added by Jakub Jelinek and
907 * Support for priority protected mutexes added by Jakub Jelinek.
909 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
910 or_IN, csb_PL, fy_NL, sr_ME.
914 * More overflow detection functions.
916 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
917 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
919 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,

923 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
924 by Masahide Washizawa.
926 * It is now possible to install audit libraries for the dynamic linker using
927 LD_AUDIT. Implemented by Ulrich Drepper.
929 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
930 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
931 For a libc and libpthread that works well on Linux 2.4 kernels, we
932 recommend using the stable 2.3 branch.
934 * The new function open_wmemstream acts like open_memstream,
935 but uses a wchar_t wide character buffer.
937 * The new function ppoll is an improved version of poll, similar to pselect.
939 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
940 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
941 renameat, unlinkat, linkat, symlinkat, readlinkat.
943 * New Linux kernel system calls: unshare,
944 inotify_init, inotify_add_watch, inotify_rm_watch.
946 * The euidaccess function is now also known by the alias eaccess,
947 for compatibility with some other systems.
949 * Timezone data updated to 2006b version.
953 * The following bugs are resolved with this release:
955 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961,

964 * As of this release, GCC 4 can be used to compile the C Library.
966 * Timezone data updated to 2005m version.
970 * The following bugs are resolved with this release:
972 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

975 777, 787, 821, 822, 823, 825
977 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
981 * Support for RFC 3678. Real implementations exist only for Linux so far.
982 Implemented by Ulrich Drepper.
984 * nscd can now cache entries persistently. Expiring entries are reloaded.
985 For speedups the cache can be shared in memory with client processes.
986 Implemented by Ulrich Drepper.
988 * nscd can now perform SELinux checks.
989 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
991 * getaddrinfo queries are now cached. Canonical name lookup is performed
993 Implemented by Ulrich Drepper.
995 * The nothrow function attribute is used when headers are used by gcc when
996 compiling C code. This can avoid significant amounts of exception
999 * The malloc functions perform more error checking and are stricter when
1000 it comes to reacting on errors. The default action is to terminate
1001 the process after showing an error message. Implemented by Ulrich Drepper.
1003 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
1004 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
1006 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
1007 namespaces using the new function dlmopen(). This feature is of course,
1008 like most other dynamic loading functionality, not available in statically
1009 linked applications. Implemented by Ulrich Drepper.
1011 * Low-overhead boundary checking variants of string and some stdio functions
1012 were added. These are to be used in conjunction with a gcc patch by
1013 Jakub Jelinek which adds calls to these functions if possible.
1014 Implemented by Jakub Jelinek and Ulrich Drepper.
1016 * Old code for several operating systems and machine architectures that
1017 have not been in working condition in a long time have been removed from
1018 the main source tree maintained by the GNU C Library's maintainers.
1019 These files are now reside in the separate `ports' source module
1020 that is usable as an add-on when building the library.
1024 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
1025 interrogate the dynamic linker, compatible with the Solaris interface.
1027 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
1028 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
1030 * getifaddrs now uses the netlink interface on Linux to get its information.
1031 Implemented by Thorsten Kukuk.
1033 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
1034 Implemented by Ulrich Drepper.
1036 * support for non-executable stacks on x86 has been added. Changes mostly
1039 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
1042 * getaddrinfo now performs destination address selection according to
1047 * Thread-safe interfaces for many functions that access locale data
1048 were added in version 2.3, but these features were omitted from NEWS.
1049 Many functions have variants with an `_l' suffix that take a `locale_t'
1050 object as a parameter rather than consulting the current locale.
1051 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
1052 create and maintain `locale_t' objects. Additionally, the new function
1053 `uselocale' sets "the current locale" (as used by functions not so
1054 parameterized) set for an individual thread. These features were added
1055 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
1057 * The functions getresuid, getresgid, setresuid, and setresgid, which
1058 have long been available on Linux, are now declared in <unistd.h>
1059 and are now also available on the Hurd.
1061 * ELF thread-local storage support (TLS) now works on x86-64.
1063 * The new dynamic string token $LIB is expanded in shared library names.
1064 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
1066 * Aldy Hernandez contributed complete software floating point support for
1067 PowerPC machines with no FPU.
1069 * fexecve is implemented on Linux.
1071 * The `btowc' function should work at least twice as fast due to
1072 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
1074 * With approriate thread add-ons cancelable functions are now implemented
1075 in libc.so as well. No need to call the function in libpthread. This
1076 change allowed to finally disable the incorrect and expensive handling
1077 of weak definition in ld.so.
1079 * Yet more PLT entries in libc.so have been removed. We finally arrived
1080 at the bare minimum. Startup times improved appropriately.
1082 * Support for the new Linux/x86 system call interface was added. The
1083 AT_SYSINFO auxiliary vector entry is recognized and handled.
1087 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
1090 * iconv (the program and the interface) now accepts empty names (excluding
1091 options like //TRANSLIT) to mean "use charset of current locale".
1093 * localedef can now transliterate characters in strings which are not in
1094 the provided charmap. The information from the input locale is used.
1096 * Prelinking support was added for ELF targets. This requires additional
1097 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
1099 * Read-only stdio streams now use mmap to speed up operation by eliminating
1100 copying and buffer underflows. To use add 'm' to the mode string of
1101 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
1103 * The malloc functions were completely rewritten by Wolfram Gloger based
1104 on Doug Lea's malloc-2.7.0.c.
1106 * Isamu Hasegawa contributed a completely new and POSIX-conformant
1107 implementation of regex.
1109 * Bruno Haible upgraded the iconv and locale implementation to support
1112 * Contents of the LC_* and LANG environment variables in the CEN style are
1113 not recognized anymore. It never was used. Change by Ulrich Drepper.
1115 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
1116 thread-local storage (TLS) ABI on some platforms.
1117 Changes by Ulrich Drepper. SH support by Kaz Kojima.
1119 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
1120 EUC-JISX0213, and TSCII.
1122 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
1123 BSD-compatible interface for getting all network interface addresses.
1124 Implementation for IPv4 by Roland McGrath.
1126 * Loading of locale data is faster due to the introduction of a locale
1127 archive. Implemented by Roland McGrath and Ulrich Drepper.
1129 * Startup times are significantly reduced by not using exported functions
1130 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
1133 * Steven Munroe contributed a port to PowerPC64/Linux.
1137 * The Hurd now uses the GNU libio implementation of stdio rather than the
1138 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
1140 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
1141 with the same behavior as the Linux system call of the same name.
1145 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
1146 128-bit long double format.
1148 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
1149 IBM1161, and IBM1162 charsets.
1151 * Andreas Jaeger contributed a port to x86-64/Linux.
1153 * Peter Bruin contributed a port to PowerPC/Hurd.
1155 * libc functions using I/O streams now can handle wide-oriented streams
1158 * optimizations in the dynamic linker. Binaries created by recent binutils
1159 versions start up quicker due to reduced time spent on relocations.
1161 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
1165 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
1166 asinh, atanh, j0 for the 128-bit long double format.
1168 * Bruno Haible updated all the code handling Unicode in some form to
1169 support Unicode 3.1.
1171 * Speed of regex for single-byte locales is back to previous levels.
1172 Patch by Isamu Hasegawa.
1174 * Alpha, SPARC, and IA-64 now also using floating stacks.
1176 * Startup time of internationalized applications greatly improved through
1177 iconv cache. Use iconvconfig to generate the cache file.
1178 Contributed by Ulrich Drepper.
1180 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
1181 severe performance problems. Patch by David Mosberger.
1183 * The Hurd port got a lot more functionality like AIO, various stdio
1184 extensions, etc. Mainly done by Roland McGrath.
1186 * mtrace can now lookup symbols in shared libraries.
1190 * Intel's IA-64 math library is largely integrated. It provides fast and
1191 accurate implementatations for most basic and standard math functions
1192 in float, double, and long double format.
1194 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
1195 and asin for the 96-bit long double format and asin, log, tan for the
1196 128-bit long double format.
1198 * The beginning of a last-bit accurate math library by IBM Haifa were added.
1199 The basic double functions exist today. Contributed by Abraham Ziv
1200 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
1201 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
1203 * An asynchronous name lookup library was added. The interface is designed
1204 after POSIX AIO. The proposal was circulated beforehand to get comments.
1205 No negative ones came in. Implemented by Ulrich Drepper.
1207 * Port to S390/64bit contributed by Martin Schwidefsky
1208 <schwidefsky@de.ibm.com>.
1210 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
1211 of functions for Linux/IA-64.
1213 * The RPC code is now thread safe. Threads can now use the same service
1214 of different services at the same time. Patch by Eric Norum
1215 <eric.norum@usask.ca> with some help by Ulrich Drepper.
1217 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
1218 family of functions for Linux/S390.
1220 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
1221 of functions for Linux/x86.
1223 * Port to Linux/CRIS contributed by Axis Communications.
1227 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
1228 we can now check for namespace violations and missing declarations. The
1229 result is that almost all headers are now Unix-compliant (as defined in
1230 the upcoming XPG6). The negative side is that some programs might need
1231 corrections, too, if they depend on the incorrect form of the headers in
1232 previous versions which defined too many symbols and included too many
1235 * regex now handles multibyte character sets correctly.
1236 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
1238 * iconv (the program) does now conform to the upcoming XPG6 and handles
1239 charmaps. Instead of the charset names the path of charmaps can be
1240 provided and the conversion happens based on this data.
1241 Contributed by Ulrich Drepper.
1243 * The locale program now provides detailed information about the installed
1248 only lists the names of the supported locales
1252 provides details such as country, language, and codeset name.
1253 Contributed by Ulrich Drepper.
1257 * The gencat program now parses the input file according to the charset
1258 selected by the LC_CTYPE category. This is important for stateful
1259 character sets. To make generating catalogs easier there is a way
1260 to overwrite the charset selected by the locale: before the first
1261 message or $ quote line the catalog can contain a line like
1263 $ codeset=ISO-8859-2
1265 to select the charset (ISO-8859-2 in this case).
1267 Implemented by Shinya Hanataka and Ulrich Drepper.
1269 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
1270 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
1271 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
1273 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
1274 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
1276 * The LANGUAGE environment variable is now ignored unless the locale is
1277 changed from the default "C" locale.
1279 * The usual bug fixes.
1283 * Greg McGary added runtime support for bounds checking using gcc's
1284 new -fbounded-pointers option. ix86 target is complete. PowerPC
1287 * Thorsten Kukuk added secure mode support to nscd.
1289 * The Berkeley db libraries have been removed.
1291 Related, the nss_db module is now in a separate package since it
1292 obviously requires a database library being available.
1294 * Wide character I/O streams implemented by Ulrich Drepper.
1296 * Functions from the extended socket API added by Ulrich Drepper.
1298 * Functions feenableexcept and fedisableexcept to control the
1299 behaviour of individual exceptions have been added by Andreas Jaeger.
1301 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
1303 * The resolver code has been updated from bind 8.2.3-T5B which supports
1304 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
1307 This change could in some situations effect backward compatibility. Since
1308 now `_res' is a thread-local instead of a global variable, modifying it
1309 in one thread does not have any effect in other threads.
1311 The resolver library was also extended to allow IPv6 as the transport
1312 protocol for the requests. This work was done by Stig Venaas.
1314 * Compatibility code for K&R C compilers has been removed from the
1315 header files. A ISO C compiler is needed to use the library
1316 (conforming to either C89 or C99 standard).
1318 * Complete rewrite of the localedef program to support multibyte character
1319 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
1320 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
1321 Implemented by Ulrich Drepper.
1323 Bruno Haible significantly improved the generation and use of the data
1324 structures for the wide character tables.
1326 * Plural handling in gettext implemented by Ulrich Drepper.
1328 * The utmp daemon has been removed.
1330 * The port to MIPS-Linux has been finished by Andreas Jaeger.
1332 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
1335 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
1337 * POSIX barriers implemented by Kaz Kylheku.
1339 * POSIX spawn function family implemented by Ulrich Drepper.
1341 * POSIX spinlocks are now available.
1343 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
1345 * the configure option --enable-kernel=X.Y.Z allows to strip out
1346 compatibility for kernel versions before X.Y.Z. This is currently only
1347 implemented for Linux.
1349 * the sockaddr_in6 structure changed. The IPv6 working group added a new
1350 field sin6_scope_id. This means that all programs using IPv6 should be
1351 recompiled. Don't expect binary compatibility with previous glibc
1354 * various conversion modules for IBM character sets contributed by
1357 * IA-64 port by Jes Sorensen and HJ Lu.
1371 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
1373 * New xdr functions are added; some rpc functions are now 64bit clean.
1375 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
1377 * Fixed known incompatibilities with glibc 2.0.
1379 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
1381 * Optimized a number of functions (especially the ELF dynamic loader).
1383 * Update timezone data files.
1385 * lots of charmaps corrections
1387 * some new locale definitions and charmaps
1392 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
1393 conform to POSIX member type requirements. Symbol versions have been
1394 adjusted as needed within the library, and for direct use by applications,
1395 but there is potential for problems if third-party libraries use
1396 struct timeval as part of their interface. This does not present
1397 a problem for X and other "essential" system libraries.
1399 * An additional locale model to support C++ Standard Library locale
1400 model and probably more was implemented by Ulrich Drepper.
1402 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
1405 * Miles Bader provided the `argp' function family to support hierachical
1406 command line argument parsing, layered on top of getopt.
1408 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
1410 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
1413 * scanf recognizes the %a and %A format for scanning floating point numbers.
1415 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
1416 information and interfaces for the available integer types.
1418 * about 130 new math functions were added to implement the ISO C9x math
1421 * the new header <complex.h> contains definitions of the complex math
1422 functions from ISO C 9X.
1424 * the new header <tgmath.h> defines generic macros to use complex or
1425 real valued functions.
1427 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
1429 * Andreas Jaeger provided a test suite for the math library.
1431 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
1433 * Ulrich Drepper added character set conversion functions (iconv).
1435 * Optimized string functions have been added.
1437 * The localedata addon is now part of glibc.
1439 * An implementation of profiling shared libraries was added by Ulrich Drepper.
1441 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
1442 daemon for NSS (nscd).
1444 Missing a better place here are some numbers on improvements. Under
1445 Linux 2.1.125 un-tar-ing the kernel sources takes
1449 using local files 12.19s 6.88s 22.91s
1451 using NIS 13.92s 8.91s 26.34s
1453 using NIS & nscd 10.37s 7.34s 25.30s
1455 using NIS+ 27.57s 30.37s 640.46s
1457 using NIS+ & nscd 10.25s 7.83s 26.51s
1459 using NIS & old nscd [1] 13.83s 8.32s 29.60s
1461 Keep in mind that non-namelookup related operations dominate above times.
1462 It was just a common complain that using NIS+ unpacking the kernel is
1465 [1] The old nscd implementation is not available anymore since it was
1466 distributed with glibc up to version 2.0.98 and thus is now replaced.
1468 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
1470 * Mark Kettenis provided a Hesiod NSS module.
1472 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
1473 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
1475 * rcmd can now handle netgroups (Dick Streefland).
1477 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
1480 * Support for the IPv6 protocol has been added to the socket API, as per the
1481 latest draft standards.
1483 * Support for Linux 2.2 has been added.
1485 * Interface changes relative to the latest 2.0.x release:

1817 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1828 * inet_ntoa is thread-safe
1830 * updwtmp is moved from libutil to libc
1832 * rewrite of cbrt function
1834 * update of timezone data
1848 * add atoll function
1850 * fix complex problems in Berkeley DB code
1852 * fix math functions
1856 * fixed lots of header problems (especially Linux/GNU specific)
1858 * dynamic loader preserves all registers
1860 * Roland McGrath provided support for handling of auxiliary objects in
1861 the ELF dynamic loader.
1863 * support for parallel builds is improved
1867 * GNU extensions are no longer declared by default. To enable them you
1868 must define the macro `_GNU_SOURCE' in your program or compile with
1871 * The library has changed from using GNU ld symbol aliases to using weak
1872 symbols where available. The ELF object file format supports weak
1873 symbols; GNU ld also supports weak symbols in the a.out format. (There
1874 is also now support for other GNU ld extensions in ELF. Use the
1875 `--with-elf' option to configure to indicate you have ELF, and
1876 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1877 of many files which contained only symbol aliases, reducing the size of
1878 the source and the compiled library; many other files were renamed to
1879 less cryptic names previously occupied by the symbol alias files.
1880 There is a new header file <elf.h> for programs which operate on
1881 files in the ELF format.
1883 * Converted to Autoconf version 2, so `configure' has more options.
1884 Run `configure --help' to see the details.
1886 * The library can now be configured to build profiling, highly-optimized
1887 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1888 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1889 `configure' enable building these extra libraries. The shared library is
1890 built by default when using both ELF and GNU ld. When shared libraries
1891 are enabled, the new library `-ldl' is available for arbitrary run-time
1892 loading of shared objects; its interface is defined in <dlfcn.h>. The
1893 new header file <link.h> gives access to the internals of the run-time
1894 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1895 application of same name on other systems and it provides information
1896 about dynamically linked binaries.
1898 * The C library now provides the run-time support code for profiling
1899 executables compiled with `-pg'. Programs can control the profiling code
1900 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1901 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1902 the support for this file format was contributed by David Mosberger-Tang.
1904 * The math code has been replaced with a math library based on fdlibm from
1905 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1906 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1907 functions. The math functions now reside in a separate library, so
1908 programs using them will need to use `-lm' their linking commands.
1910 * John C. Bowman contributed optimized ix87 assembler inline functions.
1912 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1913 mechanism similar to that found in Solaris 2. This is now used for the
1914 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1915 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1916 file controls what services are used for each individual database. This
1917 works by loading shared libraries with names specified in `nsswitch.conf',
1918 so service modules can be changed or added at any time without even
1919 relinking any program. Currently there are the file, db, and NIS based
1920 NSS services available.
1922 * The new functions `strtoq' and `strtouq' parse integer values from
1923 strings, like `strtol' and `strtoul', but they return `long long int' and
1924 `unsigned long long int' values, respectively (64-bit quantities).
1926 * The new functions `strtof' and `strtold' parse floating-point values from
1927 strings, like `strtod', but they return `float' and `long double' values,
1928 respectively (on some machines `double' and `long double' are the same).
1930 * Ulrich Drepper has contributed new implementations of the floating-point
1931 printing and reading code used in the `printf' family of functions and
1932 `strtod', `strtof', and `strtold'. These new functions are perfectly
1933 accurate, and much faster than the old ones.
1935 * The implementation of the POSIX locale model was completely rewritten by
1936 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1937 to compile the POSIX locale definition.
1939 * The former dummy implementations of the strcoll and strxfrm function are
1940 now replaced by fully functional code contributed by Ulrich Drepper. The
1941 collation information comes from the POSIX locale definitions.
1943 * The new header <langinfo.h> defines an interface for accessing
1944 various locale-dependent data (using the locale chosen with `setlocale').
1946 * Ulrich Drepper has contributed a new suite of functions for operation on
1947 wide-character and multibyte-character strings, in <wchar.h>;
1948 and classification and case conversion of wide characters, in <wctype.h>.
1949 These new functions are conforming to the ISO C, Amendement 1 specification.
1951 * There is now a second implementation of the standard I/O library available.
1952 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1953 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1955 * You can now use positional parameter specifications in format strings
1956 for the `printf' and `scanf' families of functions. For example,
1957 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1958 ``Number 6, Mr Jones''. This is mainly useful when providing different
1959 format strings for different languages, whose grammars may dictate
1960 different orderings of the values being printed. To support this
1961 feature, the interface for `register_printf_handler' has changed; see
1962 the header file <printf.h> for details.
1964 * The `printf' and `scanf' families of functions now understand a new
1965 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1966 to group numbers as indicated by the locale; for `scanf' and friends, this
1967 says to accept as valid only a number with all the proper grouping
1968 separators in the right places. In the default "C" locale, numbers are
1969 not grouped; but locales for specific countries will define the usual
1970 conventions (i.e. separate thousands with `,' in the US locale).
1972 * The pgrp functions have been regularized, slightly incompatibly but much
1973 less confusingly. The core functions are now `getpgid' and `setpgid',
1974 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1975 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1976 provided for compatibility. There is no longer an incompatible `getpgrp'
1977 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1979 * The new header file <fts.h> and suite of functions simplify programs that
1980 operate on directory trees. This code comes from 4.4 BSD.
1982 * The resolver code has been updated from the BIND 4.9.5-P1 release.
1983 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1984 NSS scheme used in glibc.
1986 * There is a new malloc debugging hook `__memalign_hook'.
1988 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
1989 `unsigned int' in <sys/types.h>. These are for compatibility only and
1990 their use is discouraged.
1992 * The `-lmcheck' library to enable standard malloc debugging hooks is now
1993 done differently, so that it works even without GNU ld.
1995 * New function `euidaccess' checks allowed access to a file like `access',
1996 but using the effective IDs instead of the real IDs.
1998 * The time zone data files have been updated for the latest and greatest
1999 local time conventions of the countries of the world.
2001 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
2004 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
2005 for formatting floating-point numbers. They are provided only for
2006 compatibility; new programs should use `sprintf' instead. There are
2007 also equivalent function for the `long double' floating-point type and
2008 all functions also exist in a reentrant form.
2010 * The new auxiliary library `-lutil' from 4.4 BSD contains various
2011 functions for maintaining the login-record files (primarily of use to
2012 system programs such as `login'), and convenient functions for
2013 allocating and initializing a pseudo-terminal (pty) device.
2015 * Ulrich Drepper has contributed new support for System V style
2016 shared memory and IPC on systems that support it.
2018 * Ulrich Drepper has contributed several miscellaneous new functions found
2019 in System V: The `hsearch' family of functions provide an effective
2020 implementation of hash tables; `a64l' and `l64a' provide a very simple
2021 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
2024 * Ulrich Drepper has contributed new reentrant counterparts for the
2025 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
2027 * Ulrich Drepper has contributed new, highly-optimized versions of several
2028 string functions for the i486/Pentium family of processors.
2030 * Ulrich Drepper has updated the Linux-specific code, based largely
2031 on work done in Hongjiu Lu's version of GNU libc for Linux.
2032 The GNU library now supports Linux versions 2.0.10 and later,
2033 using the ELF object file format (i[3456]86-*-linux).
2035 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
2037 * David Mosberger-Tang and Richard Henderson have ported the C library
2038 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
2039 dynamic linking support for ELF/Alpha.
2041 * Richard Henderson contributed several Alpha optimized assembler function
2042 for arithmetic and string handling.
2044 * Ulrich Drepper has contributed a new set of message catalog functions to
2045 support multiple languages using the <libintl.h> interface, for use with
2046 his new package GNU gettext. Translation volunteers have contributed
2047 catalogs of the library's messages in Spanish, German, and Korean.
2049 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
2050 program and the `catgets' function for reading the catalog files it
2051 creates. (The <libintl.h> interface is preferred; we include the
2052 <nl_types.h> interface using `catgets' only for source compatibility with
2053 programs already written to use it.)
2055 * New header file <values.h> gives SVID-compatible names for <limits.h>
2058 * Various new macros, declarations, and small header files for compatibility
2061 * New function `group_member' is a convenient way to check if a process has
2062 a given effective group ID.
2064 * When using GCC 2.7 and later, the socket functions are now declared in a
2065 special way so that passing an argument of type `struct sockaddr_in *',
2066 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
2067 `struct sockaddr *' type, does not generate a type-clash warning.
2069 * New function `error' declared in header file <error.h> is a convenient
2070 function for printing error messages and optionally exiting; this is the
2071 canonical function used in GNU programs. The new functions `err', `warn',
2072 and friends in header file <err.h> are the canonical 4.4 BSD interface for
2073 doing the same thing.
2075 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
2076 POSIX.2 `glob' function to do ~ and {...} expansion.
2078 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
2079 `clearenv' which is used in POSIX.9 is also available.
2081 * New function `getsid' returns session ID number on systems that support it.
2083 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
2084 files <db.h> and <mpool.h> provide a rich set of functions for several
2085 types of simple databases stored in memory and in files, and <ndbm.h> is
2086 an old `ndbm'-compatible interface using the `db' functions. Link with
2087 `-ldb' to get these functions.
2089 * New macro `strdupa' copies a string like `strdup', but uses local stack
2090 space from `alloca' instead of dynamic heap space from `malloc'.
2092 * New function `strnlen' is like `strlen' but searches only a given maximum
2093 number of characters for the null terminator. `stpncpy', `strndup' and
2094 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
2097 * New function `statfs' in header <sys/statfs.h>.
2099 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
2100 provide convenient functions for operating on blocks of null-terminated
2103 * A new suite of functions in <utmp.h> handle all the details of reading
2104 and writing the utmp file.
2106 * An implementation of the NIS/YP(tm) based NSS service was contributed by
2109 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
2110 completely POSIX compliant and also implemented the extended functionality
2111 to handle alternate digit representation and alternate era date formats.
2113 * Ulrich Drepper provided an implementation of the `strptime' function
2114 defined in XPG4.2 which transforms a string into a `struct tm' value.
2116 * Paul Eggert provided the tzselect shell script as part of the timezone
2117 code. The shell script makes it easy to select the correct timezone
2120 * The implementation of the malloc family of functions is completely replaced
2121 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
2122 The implementation uses the mmap function (if available) and it is
2123 optimized for the use in multi threaded programs.
2125 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
2126 functions. This new functionality is usable by specifying a special
2127 salt string and it is compatible with implementation on *BSD systems.
2129 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
2130 `getsubopt' to handle second level command line options, `bsd_signal'
2131 to access BSD style `signal' functionality, the obsolete `regexp' style
2134 * the `lchown' function is available on system which support this
2137 * The implementation of the shadow password handling function was contributed
2140 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
2142 * POSIX.1g support was added. The <sys/select.h> header is available,
2143 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
2144 implementation of `getaddrinfo'.
2148 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
2150 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
2151 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
2153 * The new function `daemon' from 4.4 BSD is useful for server programs that
2154 want to put themselves in the background.
2156 * Joel Sherrill has contributed support for several standalone boards that
2157 run without an operating system.
2159 * `printf', `scanf' and friends now accept a `q' type modifier for long
2160 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
2162 * All of the code taken from BSD (notably most of the math and networking
2163 routines) has been updated from the BSD 4.4-Lite release.
2165 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
2167 * The new functions `getdomainname' and `setdomainname' fetch or change the
2168 YP/NIS domain name. These are system calls which exist on systems which
2171 * The time zone data files have been updated for the latest international
2174 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
2175 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
2179 * The C library now includes support for Sun RPC, from Sun's free
2180 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
2181 are included. (There is still no support for YP.)
2183 * Tom Quinn has contributed a port of the C library to SGI machines running
2184 Irix 4 (mips-sgi-irix4).
2186 * The new `lockf' function is a simplified interface to the locking
2187 facilities of `fcntl', included for compatibility.
2189 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
2191 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
2193 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
2196 * The error message printed by `assert' for a failed assertion now includes
2197 the name of the program (if using GNU ld) and the name of the calling
2198 function (with versions of GCC that support this).
2200 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
2202 * The library now includes the <sys/mman.h> header file and memory
2203 management functions `mmap', `munmap', `mprotect', `msync', and
2204 `madvise', on systems that support those facilities.
2206 * The interface for `mcheck' has changed slightly: the function called to
2207 abort the program when an allocation inconsistency is detected now takes
2208 an argument that indicates the type of failure. The new function
2209 `mprobe' lets you request a consistency check for a particular block at
2210 any time (checks are normally done only when you call `free' or `realloc'
2213 * It is now possible to easily cross-compile the C library, building on one
2214 system a library to run on another machine and/or operating system. All
2215 you need to do is set the variable `HOST_CC' in `configparms' to the
2216 native compiler for programs to run on the machine you are building on (a
2217 few generator programs are used on Unix systems); set `CC' to the
2220 * The new function `fexecve' (only implemented on the GNU system) executes
2221 a program file given a file descriptor already open on the file.
2225 * Brendan Kehoe has contributed most of a port to the DEC Alpha
2226 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
2228 * You can set the variable `libprefix' in `configparms' to specify a prefix
2229 to be prepended to installed library files; this makes it easy to install
2230 the GNU C library to be linked as `-lgnuc' or whatever.
2232 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
2233 copies a limited number of characters from a string, and returns the
2234 address of the last character written.
2236 * You no longer need to check for whether the installed `stddef.h' is
2237 compatible with the GNU C library. configure now checks for you.
2239 * You can now define a per-stream `fileno' function to convert the
2240 stream's cookie into an integral file descriptor.
2242 * ``malloc (0)'' no longer returns a null pointer. Instead, it
2243 allocates zero bytes of storage, and returns a unique pointer which
2244 you can pass to `realloc' or `free'. The behavior is undefined if
2245 you dereference this pointer.
2247 * The C library now runs on Sony NEWS m68k machines running either
2248 NewsOS 3 or NewsOS 4.
2250 * The new `syscall' function is a system-dependent primitive function
2251 for invoking system calls. It has the canonical behavior on Unix
2252 systems, including unreliable return values for some calls (such as
2253 `pipe', `fork' and `getppid').
2255 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
2256 to `EAGAIN', which is the preferred name. On systems whose kernels
2257 use two distinct codes, the C library now translates EWOULDBLOCK to
2258 EAGAIN in every system call function.
2262 * The GNU C Library Reference Manual is now distributed with the library.
2263 `make dvi' will produce a DVI file of the printed manual.
2264 `make info' will produce Info files that you can read on line using C-h i
2265 in Emacs or the `info' program.
2266 Please send comments on the manual to bug-glibc-manual@gnu.org.
2268 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
2270 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
2272 * Jason Merrill has contributed a port to the Sequent Symmetry running
2273 Dynix version 3 (i386-sequent-dynix).
2275 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
2276 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
2278 * New function `memory_warnings' lets you arrange to get warnings when
2279 malloc is running out of memory to allocate, like Emacs gives you.
2281 * The C library now contains the relocating allocator used in Emacs 19 for
2282 its editing buffers. This allocator (ralloc) minimizes allocation
2283 overhead and fragmentation by moving allocated regions around whenever it
2284 needs to. You always refer to a ralloc'd region with a "handle" (a
2285 pointer to a pointer--an object of type `void **').
2287 * There is a new `printf' format: `%m' gives you the string corresponding
2288 to the error code in `errno'.
2290 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
2291 or `%[' conversion, but instead of filling in a fixed-sized buffer you
2292 pass, the `a' modifier says to fill in a `char **' you pass with a
2295 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
2296 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
2297 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
2299 * `mkstemp' is a traditional Unix function to atomically create and open a
2300 uniquely-named temporary file.
2304 * The standard location for the file that says what the local timezone is
2305 has changed again. It is now `/usr/local/etc/localtime' (or more
2306 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
2308 * The distribution no longer contains any files with names longer than 14
2311 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
2312 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
2314 * New functions `ttyslot' and `syslog' from 4.4 BSD.
2318 * The configuration process has changed quite a bit. The `configure'
2319 script is now used just like the configuration scripts for other GNU
2320 packages. The `sysdeps' directory hierarchy is much rearranged.
2321 The file `INSTALL' explains the new scheme in detail.
2323 * The header files no longer need to be processed into ANSI C and
2324 traditional C versions. There is just one set of files to install, and
2325 it will work with ANSI or old C compilers (including `gcc -traditional').
2327 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
2328 MIPS DECStation running Ultrix 4.
2330 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
2331 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
2332 made itself into a shared library.
2334 * Yet further improved support for the i386, running 4.3 BSD-like systems
2335 (such as Mach 3 with the Unix single-server), or System V.
2337 * New function `strncasecmp' to do case-insensitive string comparison
2338 with limited length.
2340 * New function `strsep' is a reentrant alternative to `strtok'.
2342 * New functions `scandir' and `alphasort' for searching directories.
2344 * New function `setenv' is a better interface to `putenv'.
2346 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
2347 function for traversing a directory tree.
2349 * The GNU obstack package is now also part of the C library.
2350 The new function `open_obstack_stream' creates a stdio stream that
2351 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
2352 formatted output directly to an obstack.
2354 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
2355 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
2357 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
2359 * The new functions `strfry' and `memfrob' do mysterious and wonderful
2360 things to your strings.
2362 * There are some new test programs: test-fseek, testmb, and testrand.
2364 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
2365 These ports are not finished, but are a good starting place for really
2366 supporting those systems.
2368 * `/etc/localtime' is now the standard location for the file that says what
2369 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
2370 This follows the general principle that `/etc' is the place for all local
2371 configuration files.
2373 * The C library header files now use `extern "C"' when used by the C++
2374 compiler, so the C library should now work with C++ code.
2376 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
2377 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
2380 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
2381 function which uses the `merge sort' algorithm, and is said to be
2382 significantly faster than the old GNU `qsort' function. Merge sort is
2383 now the standard `qsort' function. The new algorithm can require a lot
2384 of temporary storage; so, the old sorting function is called when the
2385 required storage is not available.
2387 * The C library now includes Michael Glad's Ultra Fast Crypt, which
2388 provides the Unix `crypt' function, plus some other entry points.
2390 * The code and header files taken from 4.4 BSD have been updated with the
2391 latest files released from Berkeley.
