10 * The feature test macro __STDC_WANT_LIB_EXT2__, from ISO/IEC TR
11 24731-2:2010, is supported to enable declarations of functions from that
12 TR. Note that not all functions from that TR are supported by the GNU C
15 * The feature test macro __STDC_WANT_IEC_60559_BFP_EXT__, from ISO/IEC TS
16 18661-1:2014, is supported to enable declarations of functions and macros
17 from that TS. Note that not all features from that TS are supported by
20 * The feature test macro __STDC_WANT_IEC_60559_FUNCS_EXT__, from ISO/IEC TS
21 18661-4:2015, is supported to enable declarations of functions and macros
22 from that TS. Note that most features from that TS are not supported by
25 * The nonstandard feature selection macros _REENTRANT and _THREAD_SAFE are
26 now treated as compatibility synonyms for _POSIX_C_SOURCE=199506L.
27 Since the GNU C Library defaults to a much newer revision of POSIX, this
28 will only affect programs that specifically request an old conformance
29 mode. For instance, a program compiled with -std=c89 -D_REENTRANT will
30 see a change in the visible declarations, but a program compiled with
31 just -D_REENTRANT, or -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT,
34 Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be
35 defined by all multithreaded code, but glibc has not required this for
38 * The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. This
39 means that in a future release, the macros “major”, “minor”, and “makedev”
40 will only be available from <sys/sysmacros.h>.
42 These macros are not part of POSIX nor XSI, and their names frequently
43 collide with user code; see for instance glibc bug 19239 and Red Hat bug
44 130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code
45 presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the
48 * New <fenv.h> features from TS 18661-1:2014 are added to libm: the
49 fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the
50 femode_t type and the FE_DFL_MODE and FE_SNANS_ALWAYS_SIGNAL macros.
52 * Integer width macros from TS 18661-1:2014 are added to <limits.h>:
53 CHAR_WIDTH, SCHAR_WIDTH, UCHAR_WIDTH, SHRT_WIDTH, USHRT_WIDTH, INT_WIDTH,
54 UINT_WIDTH, LONG_WIDTH, ULONG_WIDTH, LLONG_WIDTH, ULLONG_WIDTH; and to
55 <stdint.h>: INT8_WIDTH, UINT8_WIDTH, INT16_WIDTH, UINT16_WIDTH,
56 INT32_WIDTH, UINT32_WIDTH, INT64_WIDTH, UINT64_WIDTH, INT_LEAST8_WIDTH,
57 UINT_LEAST8_WIDTH, INT_LEAST16_WIDTH, UINT_LEAST16_WIDTH,
58 INT_LEAST32_WIDTH, UINT_LEAST32_WIDTH, INT_LEAST64_WIDTH,
59 UINT_LEAST64_WIDTH, INT_FAST8_WIDTH, UINT_FAST8_WIDTH, INT_FAST16_WIDTH,
60 UINT_FAST16_WIDTH, INT_FAST32_WIDTH, UINT_FAST32_WIDTH, INT_FAST64_WIDTH,
61 UINT_FAST64_WIDTH, INTPTR_WIDTH, UINTPTR_WIDTH, INTMAX_WIDTH,
62 UINTMAX_WIDTH, PTRDIFF_WIDTH, SIG_ATOMIC_WIDTH, SIZE_WIDTH, WCHAR_WIDTH,
65 * New <math.h> features are added from TS 18661-1:2014:
67 - Signaling NaN macros: SNANF, SNAN, SNANL.
69 - Nearest integer functions: roundeven, roundevenf, roundevenl, fromfp,
70 fromfpf, fromfpl, ufromfp, ufromfpf, ufromfpl, fromfpx, fromfpxf,
71 fromfpxl, ufromfpx, ufromfpxf, ufromfpxl.
73 - llogb functions: the llogb, llogbf and llogbl functions, and the
74 FP_LLOGB0 and FP_LLOGBNAN macros.
76 - Max-min magnitude functions: fmaxmag, fmaxmagf, fmaxmagl, fminmag,
79 - Comparison macros: iseqsig.
81 - Classification macros: iscanonical, issubnormal, iszero.
83 - Total order functions: totalorder, totalorderf, totalorderl,
84 totalordermag, totalordermagf, totalordermagl.
86 - Canonicalize functions: canonicalize, canonicalizef, canonicalizel.
88 - NaN functions: getpayload, getpayloadf, getpayloadl, setpayload,
89 setpayloadf, setpayloadl, setpayloadsig, setpayloadsigf, setpayloadsigl.
91 * The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014,
92 are added to libc. They convert a floating-point number into string.
94 * Most of glibc can now be built with the stack smashing protector enabled.
95 It is recommended to build glibc with --enable-stack-protector=strong.
96 Implemented by Nick Alcock (Oracle).
98 * The function explicit_bzero, from OpenBSD, has been added to libc. It is
99 intended to be used instead of memset() to erase sensitive data after use;
100 the compiler will not optimize out calls to explicit_bzero even if they
101 are "unnecessary" (in the sense that no _correct_ program can observe the
102 effects of the memory clear).
104 * On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined
105 to float instead of double. This does not affect the ABI of any libraries
106 that are part of the GNU C Library, but may affect the ABI of other
107 libraries that use this type in their interfaces.
109 * On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the
110 float_t and double_t types are now defined to long double instead of float
111 and double. These options are not the default, and this does not affect
112 the ABI of any libraries that are part of the GNU C Library, but it may
113 affect the ABI of other libraries that use this type in their interfaces,
114 if they are compiled or used with those options.
116 * The getentropy and getrandom functions, and the <sys/random.h> header file
119 * The buffer size for byte-oriented stdio streams is now limited to 8192
120 bytes by default. Previously, on Linux, the default buffer size on most
121 file systems was 4096 bytes (and thus remains unchanged), except on
122 network file systems, where the buffer size was unpredictable and could be
123 as large as several megabytes.
125 * The <sys/quota.h> header now includes the <linux/quota.h> header. Support
126 for the Linux quota interface which predates kernel version 2.4.22 has
129 * The malloc_get_state and malloc_set_state functions have been removed.
130 Already-existing binaries that dynamically link to these functions will
131 get a hidden implementation in which malloc_get_state is a stub. As far
132 as we know, these functions are used only by GNU Emacs and this change
133 will not adversely affect already-built Emacs executables. Any undumped
134 Emacs executables, which normally exist only during an Emacs build, should
135 be rebuilt by re-running “./configure; make” in the Emacs build tree.
137 * The “ip6-dotint” and “no-ip6-dotint” resolver options, and the
138 corresponding RES_NOIP6DOTINT flag from <resolv.h> have been removed.
139 “no-ip6-dotint” had already been the default, and support for the
140 “ip6-dotint” option was removed from the Internet in 2006.
142 * The "ip6-bytestring" resolver option and the corresponding RES_USEBSTRING
143 flag from <resolv.h> have been removed. The option relied on a
144 backwards-incompatible DNS extension which was never deployed on the
147 * The flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG,
148 RES_BLAST defined in the <resolv.h> header file have been deprecated.
149 They were already unimplemented.
151 * The "inet6" option in /etc/resolv.conf and the RES_USE_INET6 flag for
152 _res.flags are deprecated. The flag was standardized in RFC 2133, but
153 removed again from the IETF name lookup interface specification in RFC
154 2553. Applications should use getaddrinfo instead.
156 * DNSSEC-related declarations and definitions have been removed from the
157 <arpa/nameser.h> header file, and libresolv will no longer attempt to
158 decode the data part of DNSSEC record types. Previous versions of glibc
159 only implemented minimal support for the previous version of DNSSEC, which
160 is incompatible with the currently deployed version.
162 * The resource record type classification macros ns_t_qt_p, ns_t_mrr_p,
163 ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the
164 <arpa/nameser.h> header file because the distinction between RR types and
165 meta-RR types is not officially standardized, subject to revision, and
166 thus not suitable for encoding in a macro.
168 * The types res_sendhookact, res_send_qhook, re_send_rhook, and the qhook
169 and rhook members of the res_state type in <resolv.h> have been removed.
170 The glibc stub resolver did not support these hooks, but the header file
171 did not reflect that.
173 * For multi-arch support it is recommended to use a GCC which has
174 been built with support for GNU indirect functions. This ensures
175 that correct debugging information is generated for functions
176 selected by IFUNC resolvers. This support can either be enabled by
177 configuring GCC with '--enable-gnu-indirect-function', or by
178 enabling it by default by setting 'default_gnu_indirect_function'
179 variable for a particular architecture in the GCC source file
182 * GDB pretty printers have been added for mutex and condition variable
183 structures in POSIX Threads. When installed and loaded in gdb these pretty
184 printers show various pthread variables in human-readable form when read
185 using the 'print' or 'display' commands in gdb.
187 * Tunables feature added to allow tweaking of the runtime for an application
188 program. This feature can be enabled with the '--enable-tunables' configure
189 flag. The GNU C Library manual has details on usage and README.tunables has
190 instructions on adding new tunables to the library.
192 * A new version of condition variables functions have been implemented in
193 the NPTL implementation of POSIX Threads to provide stronger ordering
196 * A new version of pthread_rwlock functions have been implemented to use a more
197 scalable algorithm primarily through not using a critical section anymore to
200 Security related changes:
202 * On ARM EABI (32-bit), generating a backtrace for execution contexts which
203 have been created with makecontext could fail to terminate due to a
204 missing .cantunwind annotation. This has been observed to lead to a hang
205 (denial of service) in some Go applications compiled with gccgo. Reported
206 by Andreas Schwab. (CVE-2016-6323)
208 * The DNS stub resolver functions would crash due to a NULL pointer
209 dereference when processing a query with a valid DNS question type which
210 was used internally in the implementation. The stub resolver now uses a
211 question type which is outside the range of valid question type values.

364 * The minimum Linux kernel version that this version of the GNU C Library
365 can be used with is 3.2, except on i[4567]86 and x86_64, where Linux
366 kernel version 2.6.32 or later suffices (on architectures that already
367 required kernel versions more recent than 3.2, those requirements remain
368 unchanged). Linux 3.2 or later kernel headers are required on all
371 * The pap_AN locale has been deleted. This has been deprecated for a long
372 time. It has been replaced by pap_AW & pap_CW, both of which have long
373 been included in previous releases.
375 * The readdir_r and readdir64_r functions have been deprecated. It is
376 recommended to use readdir and readdir64 instead.
378 * The type “union wait” has been removed. It was deprecated in the early
379 1990s and never part of POSIX. Application code should use the int type
380 instead of “union wait”.
382 * A new NSS action is added to facilitate large distributed system
383 administration. The action, MERGE, allows remote user stores like LDAP
384 to be merged into local user stores like /etc/groups in order to provide
385 easy to use, updated, and managed sets of merged credentials. The new
386 action can be used by configuring it in /etc/nsswitch.conf:
387 group: files [SUCCESS=merge] nis
388 Implemented by Stephen Gallagher (Red Hat).
390 * The deprecated __malloc_initialize_hook variable has been removed from the
393 * The long unused localedef --old-style option has been removed. It hasn't
394 done anything in over 16 years. Scripts using this option can safely
397 * nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf are added to
398 libm. They are defined by TS 18661 and IEEE754-2008. The nextup functions
399 return the next representable value in the direction of positive infinity
400 and the nextdown functions return the next representable value in the
401 direction of negative infinity. These are currently enabled as GNU
404 Security related changes:
406 * An unnecessary stack copy in _nss_dns_getnetbyname_r was removed. It
407 could result in a stack overflow when getnetbyname was called with an
408 overly long name. (CVE-2016-3075)
410 * Previously, getaddrinfo copied large amounts of address data to the stack,
411 even after the fix for CVE-2013-4458 has been applied, potentially
412 resulting in a stack overflow. getaddrinfo now uses a heap allocation
413 instead. Reported by Michael Petlan. (CVE-2016-3706)
415 * The glob function suffered from a stack-based buffer overflow when it was
416 called with the GLOB_ALTDIRFUNC flag and encountered a long file name.
417 Reported by Alexander Cherepanov. (CVE-2016-1234)
419 * The Sun RPC UDP client could exhaust all available stack space when
420 flooded with crafted ICMP and UDP messages. Reported by Aldy Hernandez'
421 alloca plugin for GCC. (CVE-2016-4429)
423 * The IPv6 name server management code in libresolv could result in a memory
424 leak for each thread which is created, performs a failing naming lookup,
425 and exits. Over time, this could result in a denial of service due to
426 memory exhaustion. Reported by Matthias Schiffer. (CVE-2016-5417)

670 * Unicode 8.0.0 Support: Character encoding, character type info, and
671 transliteration tables are all updated to Unicode 8.0.0, using new
672 and/or improved generator scripts contributed by Mike FABIAN (Red Hat).
673 These updates cause user visible changes, such as the fixes for bugs
674 89, 16061, and 18568.
676 * sched_setaffinity, pthread_setaffinity_np no longer attempt to guess the
677 kernel-internal CPU set size. This means that requests that change the
678 CPU affinity which failed before (for example, an all-ones CPU mask) will
679 now succeed. Applications that need to determine the effective CPU
680 affinities need to call sched_getaffinity or pthread_getaffinity_np after
681 setting it because the kernel can adjust it (and the previous size check
682 would not detect this in the majority of cases).
684 * The fts.h header can now be used with -D_FILE_OFFSET_BITS=64. With LFS
685 the following new symbols are used: fts64_children, fts64_close,
686 fts64_open, fts64_read and fts64_set.
688 * getaddrinfo now detects certain invalid responses on an internal netlink
689 socket. If such responses are received, an affected process will
690 terminate with an error message of "Unexpected error <number> on netlink
691 descriptor <number>" or "Unexpected netlink response of size <number> on
692 descriptor <number>". The most likely cause for these errors is a
693 multi-threaded application which erroneously closes and reuses the netlink
694 file descriptor while it is used by getaddrinfo.
696 * A defect in the malloc implementation, present since glibc 2.15 (2012) or
697 glibc 2.10 via --enable-experimental-malloc (2009), could result in the
698 unnecessary serialization of memory allocation requests across threads.
699 The defect is now corrected. Users should see a substantial increase in
700 the concurent throughput of allocation requests for applications which
701 trigger this bug. Affected applications typically create and
702 destroy threads frequently. (Bug 19048 was reported and analyzed by
705 * There is now a --disable-timezone-tools configure option for disabling the
706 building and installing of the timezone related utilities (zic, zdump, and
707 tzselect). This is useful for people who build the timezone data and code
708 independent of the GNU C Library.
710 * The obsolete header <regexp.h> has been removed. Programs that require
711 this header must be updated to use <regex.h> instead.
713 * The obsolete functions bdflush, create_module, get_kernel_syms,
714 query_module and uselib are no longer available to newly linked binaries;
715 the header <sys/kdaemon.h> has been removed. These functions and header
716 were specific to systems using the Linux kernel and could not usefully be
717 used with the GNU C Library on systems with version 2.6 or later of the
720 * Optimized string, wcsmbs and memory functions for IBM z13.
721 Implemented by Stefan Liebler.
723 * Newly linked programs that define a variable called signgam will no longer
724 have it set by the lgamma, lgammaf and lgammal functions. Programs that
725 require signgam to be set by those functions must ensure that they use the
726 variable provided by the GNU C Library and declared in <math.h>, without
727 defining their own copy.
729 * The minimum GCC version that can be used to build this version of the GNU
730 C Library is GCC 4.7. Older GCC versions, and non-GNU compilers, can
731 still be used to compile programs using the GNU C Library.
733 Security related changes:
735 * An out-of-bounds value in a broken-out struct tm argument to strftime no
736 longer causes a crash. Reported by Adam Nielsen. (CVE-2015-8776)
738 * The LD_POINTER_GUARD environment variable can no longer be used to disable
739 the pointer guard feature. It is always enabled. Previously,
740 LD_POINTER_GUARD could be used to disable security hardening in binaries
741 running in privileged AT_SECURE mode. Reported by Hector Marco-Gisbert.
744 * An integer overflow in hcreate and hcreate_r could lead to an
745 out-of-bounds memory access. Reported by Szabolcs Nagy. (CVE-2015-8778)
747 * The catopen function no longer has unbounded stack usage. Reported by
750 * The nan, nanf and nanl functions no longer have unbounded stack usage
751 depending on the length of the string passed as an argument to the
752 functions. Reported by Joseph Myers. (CVE-2014-9761)
754 * A stack-based buffer overflow was found in libresolv when invoked from
755 libnss_dns, allowing specially crafted DNS responses to seize control
756 of execution flow in the DNS client. The buffer overflow occurs in
757 the functions send_dg (send datagram) and send_vc (send TCP) for the
758 NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
759 family. The use of AF_UNSPEC triggers the low-level resolver code to
760 send out two parallel queries for A and AAAA. A mismanagement of the
761 buffers used for those queries could result in the response of a query
762 writing beyond the alloca allocated buffer created by
763 _nss_dns_gethostbyname4_r. Buffer management is simplified to remove
764 the overflow. Thanks to the Google Security Team and Red Hat for
765 reporting the security impact of this issue, and Robert Holiday of
766 Ciena for reporting the related bug 18665. (CVE-2015-7547)

1058 18657, 18676, 18694, 18696, 18887.
1060 * Cache information can be queried via sysconf() function on s390 e.g. with
1061 _SC_LEVEL1_ICACHE_SIZE as argument.
1063 * A buffer overflow in gethostbyname_r and related functions performing DNS
1064 requests has been fixed. If the NSS functions were called with a
1065 misaligned buffer, the buffer length change due to pointer alignment was
1066 not taken into account. This could result in application crashes or,
1067 potentially arbitrary code execution, using crafted, but syntactically
1068 valid DNS responses. (CVE-2015-1781)
1070 * The time zone file parser has been made more robust against crafted time
1071 zone files, avoiding heap buffer overflows related to the processing of
1072 the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
1073 large time zone data files. Overly long time zone specifiers in the TZ
1074 variable no longer result in stack overflows and crashes.
1076 * A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
1077 for LD and GD on x86 and x86-64, has been implemented. You will need
1078 binutils-2.24 or later to enable this optimization.
1080 * Character encoding and ctype tables were updated to Unicode 7.0.0, using
1081 new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
1082 Hat). These updates cause user visible changes, such as the fix for bug
1085 * CVE-2014-8121 The NSS backends shared internal state between the getXXent
1086 and getXXbyYY NSS calls for the same database, causing a denial-of-service
1087 condition in some applications.
1089 * Added vector math library named libmvec with the following vectorized x86_64
1090 implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
1092 The library can be disabled with --disable-mathvec. Use of the functions is
1093 enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
1094 Shared library libmvec.so is linked in as needed when using -lm (no need to
1095 specify -lmvec explicitly for not static builds).
1096 Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.
1098 * A new fmemopen implementation has been added with the goal of POSIX
1099 compliance. The new implementation fixes the following long-standing
1100 issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
1101 old implementation is still present for use be by existing binaries.
1103 * The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
1104 releases. It has been fixed to match 2.19 and older, but binaries built
1105 against 2.20 and 2.21 might need to be recompiled. See BZ#18694.
1107 * Port to Native Client running on ARMv7-A (--host=arm-nacl).
1108 Contributed by Roland McGrath (Google).
1110 * The header <regexp.h> is deprecated, and will be removed in a future
1111 release. Use of this header will trigger a deprecation warning.
1112 Application developers should update their code to use <regex.h> instead.
1114 This header was formerly part of SUS, but was deprecated in 1994 and
1115 removed from the standard in 2001. Also, the glibc implementation
1116 leaks memory. See BZ#18681 for more details.
1120 * The following bugs are resolved with this release:

1134 * CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate
1135 too little memory for the to-be-scanned arguments and overflow the
1136 allocated buffer. The implementation now correctly computes the required
1137 buffer size when using malloc, and switches to malloc from alloca as
1140 * A new semaphore algorithm has been implemented in generic C code for all
1141 machines. Previous custom assembly implementations of semaphore were
1142 difficult to reason about or ensure that they were safe. The new version
1143 of semaphore supports machines with 64-bit or 32-bit atomic operations.
1144 The new semaphore algorithm is used by sem_init, sem_open, sem_post,
1145 sem_wait, sem_timedwait, sem_trywait, and sem_getvalue.
1147 * Port to Altera Nios II has been contributed by Mentor Graphics.
1149 * Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp
1150 implementations for powerpc64/powerpc64le.
1151 Implemented by Adhemerval Zanella (IBM).
1153 * Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64
1154 and powerpc64le. This may improve lock scaling of existing programs on
1155 HTM capable systems. The lock elision code is only enabled with
1156 --enable-lock-elision=yes. Also, the TSX lock elision implementation for
1157 powerpc will issue a transaction abort on every syscall to avoid side
1158 effects being visible outside transactions.
1160 * Optimized strcpy, stpcpy, strchrnul and strrchr implementations for
1161 AArch64. Contributed by ARM Ltd.
1163 * i386 memcpy functions optimized with SSE2 unaligned load/store.
1165 * CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag
1166 under certain input conditions resulting in the execution of a shell for
1167 command substitution when the application did not request it. The
1168 implementation now checks WRDE_NOCMD immediately before executing the
1169 shell and returns the error WRDE_CMDSUB as expected.
1171 * CVE-2012-3406 printf-style functions could run into a stack overflow when
1172 processing format strings with a large number of format specifiers.
1174 * CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an
1175 infinite loop if the DNS response contained a PTR record of an unexpected
1178 * The minimum GCC version that can be used to build this version of the GNU
1179 C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can
1180 still be used to compile programs using the GNU C Library.
1182 * The GNU C Library is now built with -Werror by default. This can be
1183 disabled by configuring with --disable-werror.
1185 * New locales: tu_IN, bh_IN, raj_IN, ce_RU.
1187 * The obsolete sigvec function has been removed. This was the original
1188 4.2BSD interface that inspired the POSIX.1 sigaction interface, which
1189 programs have been using instead for about 25 years. Of course, ABI
1190 compatibility for old binaries using sigvec remains intact.
1192 * Merged gettext 0.19.3 into the intl subdirectory. This fixes building
1193 with newer versions of bison.
1195 * Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions.
1196 The original MIPS o32 hard-float ABI requires an FPU where double-precision
1197 registers overlay two consecutive single-precision registers. MIPS32R2
1198 introduced a new FPU mode (FR=1) where double-precision registers extend the
1199 corresponding single-precision registers which is incompatible with the
1200 o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both
1201 require the use of FR=1 making a transition necessary. New o32 ABI
1202 extensions enable users to migrate over time from the original o32 ABI
1203 through to the updated o32 FP64 ABI. To achieve this the dynamic linker now
1204 tracks the ABI of any loaded object and verifies that new objects are
1205 compatible. Mode transitions will also be requested as required and
1206 unsupportable objects will be rejected. The ABI checks include both soft and
1207 hard float ABIs for o32, n32 and n64.
1209 GCC 5 with GNU binutils 2.25 onwards:
1210 It is strongly recommended that all o32 system libraries are built using the
1211 new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible
1212 with the original and all new o32 ABI extensions. Configure a MIPS GCC
1213 compiler using --with-fp-32=xx to set this by default.
1217 * The following bugs are resolved with this release:
1219 6804, 9894, 11505, 12994, 13347, 13651, 14308, 14770, 15119, 15132, 15347,

1225 16695, 16701, 16706, 16707, 16712, 16713, 16714, 16724, 16731, 16739,

1227 16796, 16799, 16800, 16815, 16823, 16824, 16831, 16838, 16839, 16849,
1228 16854, 16876, 16877, 16878, 16882, 16885, 16888, 16890, 16892, 16912,
1229 16915, 16916, 16917, 16918, 16922, 16927, 16928, 16932, 16943, 16958,
1230 16965, 16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022,
1231 17031, 17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078,
1232 17079, 17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150,
1233 17153, 17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354.
1235 * Reverted change of ABI data structures for s390 and s390x:
1236 On s390 and s390x the size of struct ucontext and jmp_buf was increased in
1237 2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions
1238 of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp
1239 are preserved pointing straight to the same implementation as the old ones.
1240 Given that, new callers will simply provide a too-big buffer to these
1241 functions. Any applications/libraries out there that embed jmp_buf or
1242 ucontext_t in an ABI-relevant data structure that have already been rebuilt
1243 against 2.19 headers will have to rebuilt again. This is necessary in any
1244 case to revert the breakage in their ABI caused by the glibc change.
1246 * Support for file description locks is added to systems running the
1247 Linux kernel. The standard file locking interfaces are extended to
1248 operate on file descriptions, not file descriptors, via the use of
1249 F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks
1250 are associated with an open file instead of a process.
1252 * Optimized strchr implementation for AArch64. Contributed by ARM Ltd.
1254 * The minimum Linux kernel version that this version of the GNU C Library
1255 can be used with is 2.6.32.
1257 * Running the testsuite no longer terminates as soon as a test fails.
1258 Instead, a file tests.sum (xtests.sum from "make xcheck") is generated,
1259 with PASS or FAIL lines for individual tests. A summary of the results is
1260 printed, including a list of failing lists, and "make check" exits with
1261 error status if there were any unexpected failures. "make check
1262 stop-on-test-failure=y" may be used to keep the old behavior.
1264 * The am33 port, which had not worked for several years, has been removed
1267 * The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer
1268 supported; they now act the same as _DEFAULT_SOURCE (but generate a
1269 warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that
1270 conflicted with POSIX (support for which was removed in 2.19), the
1271 interfaces those macros enabled remain available when compiling with
1272 _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature
1273 test macros defined.
1275 * Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd.
1277 * Added support for TX lock elision of pthread mutexes on s390 and s390x.
1278 This may improve lock scaling of existing programs on TX capable systems.
1279 The lock elision code is only built with --enable-lock-elision=yes and
1280 then requires a GCC version supporting the TX builtins. With lock elision
1281 default mutexes are elided via __builtin_tbegin, if the cpu supports
1282 transactions. By default lock elision is not enabled and the elision code
1285 * CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not
1286 copy the path argument. This allowed programs to cause posix_spawn to
1287 deference a dangling pointer, or use an unexpected pathname argument if
1288 the string was modified after the posix_spawn_file_actions_addopen
1291 * All supported architectures now use the main glibc sysdeps directory
1292 instead of some being in a separate "ports" directory (which was
1293 distributed separately before glibc 2.17).
1295 * The NPTL implementation of POSIX pthreads is no longer an "add-on".
1296 On configurations that support it (all Linux configurations), it's now
1297 used regardless of the --enable-add-ons switch to configure. It is no
1298 longer possible to build such configurations without pthreads support.
1300 * Locale names, including those obtained from environment variables (LANG
1301 and the LC_* variables), are more tightly checked for proper syntax.
1302 setlocale will now fail (with EINVAL) for locale names that are overly
1303 long, contain slashes without starting with a slash, or contain ".." path
1304 components. (CVE-2014-0475) Previously, some valid locale names were
1305 silently replaced with the "C" locale when running in AT_SECURE mode
1306 (e.g., in a SUID program). This is no longer necessary because of the
1309 * On x86-64, the dynamic linker's lazy-binding support is now compatible
1310 with application code using Intel MPX instructions. (With all previous
1311 versions, the MPX register state could be clobbered when making calls
1312 into or out of a shared library.) Note that while the new dynamic
1313 linker is compatible with all known x86 hardware whether or not it
1314 supports Intel MPX, some x86 instruction-set emulators might fail to
1315 handle the new instruction encodings. This is known to affect Valgrind
1316 versions up through 3.9 (but will be fixed in the forthcoming 3.10
1317 release), and might affect other tools that do instruction emulation.
1319 * Support for loadable gconv transliteration modules has been removed.
1320 The support for transliteration modules has been non-functional for
1321 over a decade, and the removal is prompted by security defects. The
1322 normal gconv conversion modules are still supported. Transliteration
1323 with //TRANSLIT is still possible, and the //IGNORE specifier
1324 continues to be supported. (CVE-2014-5119)
1326 * Decoding a crafted input sequence in the character sets IBM933, IBM935,
1327 IBM937, IBM939, IBM1364 could result in an out-of-bounds array read,
1328 resulting a denial-of-service security vulnerability in applications which
1329 use functions related to iconv. (CVE-2014-6040)
1333 * The following bugs are resolved with this release:

1352 16431, 16453, 16474, 16506, 16510, 16529
1354 * Slovenian translations for glibc messages have been contributed by the
1355 Translation Project's Slovenian team of translators.
1357 * The public headers no longer use __unused nor __block. This change is to
1358 support compiling programs that are derived from BSD sources and use
1359 __unused internally, and to support compiling with Clang's -fblock
1360 extension which uses __block.
1362 * CVE-2012-4412 The strcoll implementation caches indices and rules for
1363 large collation sequences to optimize multiple passes. This cache
1364 computation may overflow for large collation sequences and may cause a
1365 stack or buffer overflow. This is now fixed to use a slower algorithm
1366 which does not use a cache if there is an integer overflow.
1368 * CVE-2012-4424 The strcoll implementation uses malloc to cache indices and
1369 rules for large collation sequences to optimize multiple passes and falls
1370 back to alloca if malloc fails, resulting in a possible stack overflow.
1371 The implementation now falls back to an uncached collation sequence lookup
1374 * CVE-2013-4788 The pointer guard used for pointer mangling was not
1375 initialized for static applications resulting in the security feature
1376 being disabled. The pointer guard is now correctly initialized to a
1377 random value for static applications. Existing static applications need
1378 to be recompiled to take advantage of the fix (bug 15754).
1380 * CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes
1381 to the d_name member of struct dirent, or omit the terminating NUL
1382 character. (Bugzilla #14699).
1384 * CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and
1385 aligned_alloc functions could allocate too few bytes or corrupt the
1386 heap when passed very large allocation size values (Bugzilla #15855,
1389 * CVE-2013-4458 Stack overflow in getaddrinfo with large number of results
1390 for AF_INET6 has been fixed (Bugzilla #16072).
1392 * New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW,
1393 pap_CW, quz_PE, the_NP.
1395 * Substantially revised locales: gd_GB, ht_HT
1397 * The LC_ADDRESS field was updated to support country_car for almost all
1400 * ISO 1427 definitions were updated.
1402 * ISO 3166 definitions were updated.
1404 * The localedef utility now supports --big-endian and --little-endian
1405 command-line options to generate locales for a different system from that
1406 for which the C library was built.
1408 * Binary locale files now only depend on the endianness of the system for
1409 which they are generated and not on other properties of that system. As a
1410 consequence, binary files generated with new localedef may be incompatible
1411 with old versions of the GNU C Library, and binary files generated with
1412 old localedef may be incompatible with this version of the GNU C Library,
1413 in the following circumstances:
1415 + Locale files may be incompatible on m68k systems.
1417 + Locale archive files (but not separate files for individual locales) may
1418 be incompatible on systems where plain "char" is signed.
1420 * The configure option --disable-versioning has been removed. Builds with
1421 --disable-versioning had not worked for several years.
1423 * ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh,
1424 cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue).
1426 * SystemTap probes for malloc have been introduced.
1428 * SystemTap probes for slow multiple precision fallback paths of
1429 transcendental functions have been introduced.
1431 * Support for powerpc64le has been added.
1433 * The soft-float powerpc port now supports e500 processors.
1435 * Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64.
1437 * A new feature test macro _DEFAULT_SOURCE is available to enable the same
1438 set of header declarations that are enabled by default, even when other
1439 feature test macros or compiler options such as -std=c99 would otherwise
1440 disable some of those declarations.
1442 * The _BSD_SOURCE feature test macro no longer enables BSD interfaces that
1443 conflict with POSIX. The libbsd-compat library (which was a dummy library
1444 that did nothing) has also been removed.
1446 * Preliminary documentation about Multi-Thread, Async-Signal and
1447 Async-Cancel Safety has been added.
1449 * Change of ABI data structures for s390 and s390x:
1450 On s390 and s390x the size of struct ucontext and jmp_buf was increased to
1451 allow for future hardware extensions. All library functions that accept or
1452 return these structures were versioned in order to provide backwards
1453 compatibility with existing code. However, not all cases can be handled
1454 with interface versioning. If an application embeds either structure into
1455 another structure and that structure is passed to another compilation unit
1456 which expects the newer larger-sized object then any access to the new
1457 fields will result in undefined behaviour. Similarly any access to fields
1458 that were moved by the enlarging of the structures will cause undefined
1459 behaviour. To fix the undefined behaviour all objects that are part of the
1460 final in-memory image must agree on the size of structures, and this may
1461 require recompilation.
1465 * The following bugs are resolved with this release:

1482 * CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal
1483 has been fixed by disabling the use of pt_chown (Bugzilla #15755).
1484 Distributions can re-enable building and using pt_chown via the new configure
1485 option `--enable-pt_chown'. Enabling the use of pt_chown carries with it
1486 considerable security risks and should only be used if the distribution
1487 understands and accepts the risks.
1489 * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla
1492 * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been
1493 fixed (Bugzilla #15330).
1495 * Add support for calling C++11 thread_local object destructors on thread
1496 and program exit. This needs compiler support for offloading C++11
1497 destructor calls to glibc.
1499 * Improved worst case performance of libm functions with double inputs and
1502 * Support for priority inherited mutexes in pthread condition variables on
1503 non-x86 architectures.
1505 * Port to Xilinx MicroBlaze contributed by David Holsgrove.
1507 * Optimized string functions for AArch64. Implemented by Marcus Shawcroft.
1509 * Optimized string functions for ARM. Implemented by Will Newton and
1512 * Optimized libm functions for SPARC. Implemented by David S. Miller.
1514 * Support for building more of ARM glibc as Thumb-2 code. Implemented by
1517 * Support for building most of MIPS glibc as MIPS16 code. Implemented by
1518 Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov.
1520 * Added a benchmark framework to track performance of functions in glibc.
1522 * New <math.h> macro named issignaling to check for a signaling NaN (sNaN).
1523 It is based on draft TS 18661 and currently enabled as a GNU extension.
1525 * On Linux, the clock function now uses the clock_gettime system call
1526 for improved precision, rather than old times system call.
1528 * Added support for version-3 tz format files. This is needed when using
1529 the tz database release 2013e or later, and affects a few unusual cases --
1530 currently only TZ='America/Godthab' for time stamps after 2037.
1532 * Added new API functions pthread_getattr_default_np and
1533 pthread_setattr_default_np to get and set the default pthread
1534 attributes of a process.
1536 * Added support for TSX lock elision for pthread mutexes on i386 and x86-64.
1537 This may improve lock scaling of existing programs on TSX capable systems.
1538 When the --enable-lock-elision=yes parameter is specified at configure
1539 time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT
1542 * Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10
1543 availability). Implemented by Ryan S. Arnold.
1545 * Support added for POWER8 platform. Implemented by Ryan S. Arnold.
1549 * The following bugs are resolved with this release:

1565 14879, 14889, 14893, 14898, 14914.
1567 * Optimization of memcpy for MIPS.
1569 * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with
1570 EMFILE has been fixed (Bugzilla #14889).
1572 * The add-on ports collection is now distributed in the "ports" subdirectory
1573 of the main GNU C Library distribution, rather than separately.
1575 * Port to ARM AArch64 contributed by Linaro.
1577 * Support for STT_GNU_IFUNC symbols added for s390 and s390x.
1578 Optimized versions of memcpy, memset, and memcmp added for System z10 and
1580 Implemented by Andreas Krebbel.
1582 * The new function secure_getenv allows secure access to the environment,
1583 returning NULL if running in a SUID/SGID process. This function replaces
1584 the internal function __secure_getenv.
1586 * SystemTap static probes have been added into the dynamic linker.
1587 Implemented by Gary Benson.
1589 * Optimizations of string functions strstr, strcasestr and memmem.
1590 Implemented by Maxim Kuvyrkov.
1592 * The minimum Linux kernel version that this version of the GNU C Library
1593 can be used with is 2.6.16.
1595 * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for
1596 powerpc POWER7. Implemented by Will Schmidt.
1598 * New configure option --disable-nscd builds the C library such that it
1599 never attempts to contact the Name Service Caching Daemon (nscd).
1600 New configure option --disable-build-nscd avoids building nscd itself;
1601 this is the default if --disable-nscd is used.
1603 * Improved support for cross-compilation, including cross-testing and
1604 bootstrap builds without a previously built glibc.
1606 * Several testsuite tests are now able to test multiple IFUNC variants of an
1607 interface, rather than just testing the one that would be chooen by
1610 * New configure options --with-bugurl and --with-pkgversion, for
1611 distributors to use to embed their bug-reporting and package version
1612 information in --help and --version output.
1614 * The ttyname and ttyname_r functions on Linux now fall back to searching for
1615 the tty file descriptor in /dev/pts or /dev if /proc is not available. This
1616 allows creation of chroots without the procfs mounted on /proc.
1618 * The `crypt' function now fails if passed salt bytes that violate the
1619 specification for those values. On Linux, the `crypt' function will
1620 consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is
1621 enabled, and fail on encrypted strings using the MD5 or DES algorithm
1622 when the mode is enabled.
1624 * The `clock_*' suite of functions (declared in <time.h>) is now available
1625 directly in the main C library. Previously it was necessary to link with
1626 -lrt to use these functions. This change has the effect that a
1627 single-threaded program that uses a function such as `clock_gettime' (and
1628 is not linked with -lrt) will no longer implicitly load the pthreads
1629 library at runtime and so will not suffer the overheads associated with
1630 multi-thread support in other code such as the C++ runtime library.
1632 * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ,
1637 * The following bugs are resolved with this release:

1663 * Support for the x32 ABI on x86-64 added. The x32 target is selected by
1664 configuring glibc with:
1665 BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32'
1666 Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info.
1667 Implemented by H.J. Lu.
1671 + define static_assert
1673 + do not declare gets
1675 + declare at_quick_exit and quick_exit also for ISO C11
1677 + aligned_alloc. NB: The code is deliberately allows the size parameter
1678 to not be a multiple of the alignment. This is a moronic requirement
1679 in the standard but it is only a requirement on the caller, not the
1682 + timespec_get added
1684 + uchar.h support added
1686 + CMPLX, CMPLXF, CMPLXL added
1688 Implemented by Ulrich Drepper.
1690 * Support for the IA-64 has been moved to ports.
1692 * Remove support for anything but ELF binary format
1694 * Checking versions of poll, ppoll added.
1695 Implemented by Ulrich Drepper.
1697 * More generic and 64-bit performance optimizations to math functions.
1698 Implemented by Ulrich Drepper.
1700 * New configure option --enable-obsolete-rpc makes the deprecated RPC
1701 headers and functions available at compile time as they were before
1702 version 2.14. This option will be removed at some time in the future
1703 after the TI-RPC library becomes fully sufficient for the needs of
1704 existing applications.
1706 * Compatibility code for Linux kernel versions before 2.4 has been removed.
1707 Note that glibc is not expected to work with any Linux kernel version
1710 * New header <sys/auxv.h> and function getauxval allowing easy access to
1711 the AT_* key-value pairs passed from the Linux kernel. The header also
1712 defines the HWCAP_* bits associated with the AT_HWCAP key.
1714 * New locales: mag_IN
1716 * New configure option --enable-systemtap builds SystemTap static probes
1717 into libc for setjmp and longjmp and into libpthread for various operations.
1718 So far the setjmp/longjmp probes and some of the libpthread probes are
1719 provided only for i*86 and x86_64.
1720 Implemented by Roland McGrath and Rayson Ho.
1722 * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva.
1724 * More optimized functions for PowerPC. Implemented by Adhemerval Zanella
1727 * More optimized functions for SPARC. Implemented by David S. Miller.
1729 * Improved support for cross-compilation, especially bootstrap builds
1730 without a previously built glibc.
1732 * Ports for the TILE-Gx and TILEPro families of processors. Contributed by
1733 Chris Metcalf from Tilera.
1735 * Support for the old ARM ABI has been removed from ports. Only the EABI is
1736 now supported for ARM processors.
1738 * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3
1739 as the name of the dynamic linker, to distinguish it from the
1740 /lib/ld-linux.so.3 dynamic linker used for the base EABI.
1742 * Support for CRIS has been removed from ports.
1744 * A new class of installed header has been documented for low-level
1745 platform-specific functionality. PowerPC added the first instance with a
1746 function to provide time base register access. Contributed by Tulio
1747 Magno Quites Machado Filho.
1749 * ix86 configurations now install header files that are consistent with
1750 what x86-64 configurations install. These same header files can be used
1751 for -m32, -m64, or -mx32 builds.
1752 Contributed by H.J. Lu.
1754 * Math library bug fixes. A thorough audit of all open math library bugs was
1755 conducted by Joseph Myers. Significant progress was made on many math
1756 library bugs resulting in more accurate exceptions and function results.
1757 Many thanks to all those that contributed including Andreas Jaeger for his
1758 patch review and work on the x87 trigonometric instruction issues.
1760 * Timezone data is no longer installed. Timezone-related binaries and scripts
1761 will continue to be installed. Users should obtain their timezone data from
1762 their distribution provider or from the tzdata package at
1763 <ftp://munnari.oz.au/pub/>.
1767 * The following bugs are resolved with this release:

1777 * New program pldd to list loaded object of a process
1778 Implemented by Ulrich Drepper.
1780 * Add nss_db support back to glibc. No more dependency on Berkeley db
1781 and support for initgroups lookups.
1782 Implemented by Ulrich Drepper.
1784 * Optimized strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-32.
1785 Contributed by HJ Lu.
1787 * Improved strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-64.
1788 Contributed by HJ Lu.
1790 * Optimized strcat, strncat on x86-64 and optimized wcscmp, wcslen, strnlen
1791 on x86-32 and x86-64.
1792 Contributed by Liubov Dmitrieva.
1794 * Optimized strchr and strrchr for SSE on x86-32.
1795 Contributed by Liubov Dmitrieva.
1797 * Optimized memchr, memrchr, rawmemchr, memcmp, wmemcmp, wcschr, wcscpy
1798 for x86-64 and x86-32.
1799 Contributed by Liubov Dmitrieva.
1801 * New interfaces: scandirat, scandirat64
1802 Implemented by Ulrich Drepper.
1804 * Checking versions of FD_SET, FD_CLR, and FD_ISSET added.
1805 Implemented by Ulrich Drepper.
1807 * nscd now also caches the netgroup database.
1808 Implemented by Ulrich Drepper.
1810 * Integrate libm with gcc's -ffinite-math-only option.
1811 Implemented by Ulrich Drepper.
1813 * Lots of generic, 64-bit, and x86-64-specific performance optimizations
1814 to math functions. Implemented by Ulrich Drepper.
1816 * Optimized strcasecmp and strncasecmp for AVX on x86-64.
1817 Implemented by Ulrich Drepper.
1819 * New Linux interfaces: process_vm_readv, process_vm_writev
1821 * Optimized strcasecmp and strncasecmp for SSSE3 and SSE4.2 on x86-32.
1822 Implemented by Ulrich Drepper.
1824 * Optimized nearbyint and strcasecmp for PPC.
1825 Implemented by Adhemerval Zanella.
1827 * New locales: bho_IN, unm_US, es_CU, ta_LK
1831 * The following bugs are resolved with this release:

1842 12795, 12811, 12813, 12814, 12841
1844 * The RPC implementation in libc is obsoleted. Old programs keep working
1845 but new programs cannot be linked with the routines in libc anymore.
1846 Programs in need of RPC functionality must be linked against TI-RPC.
1847 The TI-RPC implementation is IPv6 enabled and there are other benefits.
1849 Visible changes of this change include (obviously) the inability to link
1850 programs using RPC functions without referencing the TI-RPC library and the
1851 removal of the RPC headers from the glibc headers.
1852 Implemented by Ulrich Drepper.
1854 * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at,
1855 syncfs, setns, sendmmsg
1857 * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH,
1858 yue_HK, lij_IT, mhr_RU
1860 * New encodings: CP770, CP771, CP772, CP773, CP774
1862 * New program sotruss to trace calls through PLTs
1863 Implemented by Ulrich Drepper.
1865 * The malloc hook implementation is marked deprecated and will be removed
1866 from the default implementation in the next version. The design never
1867 worked ever since the introduction of threads. Even programs which do
1868 not create threads themselves can use multiple threads created internally.
1872 * The following bugs are resolved with this release:
1874 3268, 6812, 7066, 10085, 10484, 10563, 10851, 11149, 11155, 11577, 11611,

1908 EI_ABIVERSION field in the ELF header.
1909 Implemented by Ulrich Drepper.
1911 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
1912 will not be used to fill in password fields in the passwd.byname replies.
1913 Instead it is used to synthesize the shadow.byname table, should it be
1914 missing. This is a useful mode in some installations involving Solaris.
1915 Implemented by Ulrich Drepper.
1917 * New locales: kok_IN, sq_MK, cv_RU
1921 * The following bugs are resolved with this release:
1923 3270, 7094, 9924, 9986, 10011, 10085, 10107, 10159, 10162, 10166, 10183,

1957 * AVX support in x86-64 auditing support in ld.so.
1958 Implemented by H.J. Lu.
1960 * STB_GNU_UNIQUE support added.
1961 Implemented by Ulrich Drepper.
1963 * Implement second fallback mode for optimized DNS lookup for even more
1964 broken environments. If two requests from the same port are not
1965 handled correctly close the socket and open a new one before sending
1966 the second request. The 'single-request-reopen' option in /etc/resolv.conf
1967 can be used to select this mode right away, instead of rediscovering the
1968 necessity is every process again.
1969 Implemented by Ulrich Drepper.
1971 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
1972 Implemented by Adam Tkac.

2011 * Support for selecting between multiple function definitions at runtime
2012 using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
2014 * The libcrypt library can now use the hash function implementations in
2015 NSS. Implemented by Ulrich Drepper.
2017 * The malloc implementation can be compiled to be less memory efficient
2018 but higher performing in multi-threaded programs.
2019 Implemented by Ulrich Drepper.
2021 * New locales: nan_TW@latin, ks_IN
2023 * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
2024 Implemented by Ulrich Drepper.
2026 * Extended printf hook support. It is possible to use user-defined types
2027 and extend existing format specifiers.
2028 Implemented by Ulrich Drepper.
2030 * Handling for group shadow files has been added.
2031 Implemented by Ulrich Drepper.
2033 * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
2034 servers (the case, e.g., for some people using the built-in DNS
2035 server in ADSL modems/routers). There is a once-per-process timeout
2036 in case of a broken server. To avoid it, users can run nscd or put
2037 'options single-request' in /etc/resolv.conf.
2038 Implemented by Ulrich Drepper.

2064 Implemented by Eric Blake.
2066 * New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2
2068 * Implement "e" option for popen to open file descriptor with the
2069 close-on-exec flag set. Implemented by Ulrich Drepper.
2071 * Implement "b" mode for fmemopen. In this mode writes writes don't
2072 implicitly add a NUL byte and seeks from the end of the buffer really
2073 use the buffer end, not the string length as the basis.
2074 Implemented by Ulrich Drepper.
2076 * Many functions, exported and internal, now atomically set the close-on-exec
2077 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
2079 * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
2081 Implemented by Pravin Satpute.

2207 3225, 3251, 3252, 3253, 3273
2209 * For Linux, the sorting of addresses returned by getaddrinfo now also
2210 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
2211 Implemented by Ulrich Drepper.
2213 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
2214 Implemented by Ulrich Drepper.
2216 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
2218 * New iconv module for MIK. Contributed by Alexander Shopov.
2220 * For sites with broken group and/or passwd database, the auto-propagate
2221 option of nscd can prevent creating ID lookup entries from the results
2222 of a name lookup and vice versa. This usually is no problem but some
2223 site might have problems with the default behavior.
2224 Implemented by Ulrich Drepper.
2226 * Iterating over entire database in NIS can be slow. With the
2227 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
2228 to trade time for memory. The entire database will be read at once.
2229 Implemented by Ulrich Drepper.
2231 * The interfaces introduced in RFC 3542 have been implemented by
2234 * Support for the new ELF hash table format was added by Ulrich Drepper.
2236 * Support for priority inheritance mutexes added by Jakub Jelinek and
2239 * Support for priority protected mutexes added by Jakub Jelinek.
2241 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
2242 or_IN, csb_PL, fy_NL, sr_ME.
2246 * More overflow detection functions.
2248 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
2249 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
2251 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,
2252 IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144,

2254 IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
2255 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
2256 by Masahide Washizawa.
2258 * It is now possible to install audit libraries for the dynamic linker using
2259 LD_AUDIT. Implemented by Ulrich Drepper.
2261 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
2262 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
2263 For a libc and libpthread that works well on Linux 2.4 kernels, we
2264 recommend using the stable 2.3 branch.
2266 * The new function open_wmemstream acts like open_memstream,
2267 but uses a wchar_t wide character buffer.
2269 * The new function ppoll is an improved version of poll, similar to pselect.
2271 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
2272 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
2273 renameat, unlinkat, linkat, symlinkat, readlinkat.
2275 * New Linux kernel system calls: unshare,
2276 inotify_init, inotify_add_watch, inotify_rm_watch.
2278 * The euidaccess function is now also known by the alias eaccess,
2279 for compatibility with some other systems.
2281 * Timezone data updated to 2006b version.
2285 * The following bugs are resolved with this release:
2287 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961,

2296 * As of this release, GCC 4 can be used to compile the C Library.
2298 * Timezone data updated to 2005m version.
2302 * The following bugs are resolved with this release:
2304 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

2309 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
2313 * Support for RFC 3678. Real implementations exist only for Linux so far.
2314 Implemented by Ulrich Drepper.
2316 * nscd can now cache entries persistently. Expiring entries are reloaded.
2317 For speedups the cache can be shared in memory with client processes.
2318 Implemented by Ulrich Drepper.
2320 * nscd can now perform SELinux checks.
2321 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
2323 * getaddrinfo queries are now cached. Canonical name lookup is performed
2325 Implemented by Ulrich Drepper.
2327 * The nothrow function attribute is used when headers are used by gcc when
2328 compiling C code. This can avoid significant amounts of exception
2331 * The malloc functions perform more error checking and are stricter when
2332 it comes to reacting on errors. The default action is to terminate
2333 the process after showing an error message. Implemented by Ulrich Drepper.
2335 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
2336 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
2338 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
2339 namespaces using the new function dlmopen(). This feature is of course,
2340 like most other dynamic loading functionality, not available in statically
2341 linked applications. Implemented by Ulrich Drepper.
2343 * Low-overhead boundary checking variants of string and some stdio functions
2344 were added. These are to be used in conjunction with a gcc patch by
2345 Jakub Jelinek which adds calls to these functions if possible.
2346 Implemented by Jakub Jelinek and Ulrich Drepper.
2348 * Old code for several operating systems and machine architectures that
2349 have not been in working condition in a long time have been removed from
2350 the main source tree maintained by the GNU C Library's maintainers.
2351 These files are now reside in the separate `ports' source module
2352 that is usable as an add-on when building the library.
2356 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
2357 interrogate the dynamic linker, compatible with the Solaris interface.
2359 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
2360 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
2362 * getifaddrs now uses the netlink interface on Linux to get its information.
2363 Implemented by Thorsten Kukuk.
2365 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
2366 Implemented by Ulrich Drepper.
2368 * support for non-executable stacks on x86 has been added. Changes mostly
2371 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
2374 * getaddrinfo now performs destination address selection according to
2379 * Thread-safe interfaces for many functions that access locale data
2380 were added in version 2.3, but these features were omitted from NEWS.
2381 Many functions have variants with an `_l' suffix that take a `locale_t'
2382 object as a parameter rather than consulting the current locale.
2383 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
2384 create and maintain `locale_t' objects. Additionally, the new function
2385 `uselocale' sets "the current locale" (as used by functions not so
2386 parameterized) set for an individual thread. These features were added
2387 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
2389 * The functions getresuid, getresgid, setresuid, and setresgid, which
2390 have long been available on Linux, are now declared in <unistd.h>
2391 and are now also available on the Hurd.
2393 * ELF thread-local storage support (TLS) now works on x86-64.
2395 * The new dynamic string token $LIB is expanded in shared library names.
2396 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
2398 * Aldy Hernandez contributed complete software floating point support for
2399 PowerPC machines with no FPU.
2401 * fexecve is implemented on Linux.
2403 * The `btowc' function should work at least twice as fast due to
2404 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
2406 * With approriate thread add-ons cancelable functions are now implemented
2407 in libc.so as well. No need to call the function in libpthread. This
2408 change allowed to finally disable the incorrect and expensive handling
2409 of weak definition in ld.so.
2411 * Yet more PLT entries in libc.so have been removed. We finally arrived
2412 at the bare minimum. Startup times improved appropriately.
2414 * Support for the new Linux/x86 system call interface was added. The
2415 AT_SYSINFO auxiliary vector entry is recognized and handled.
2419 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
2422 * iconv (the program and the interface) now accepts empty names (excluding
2423 options like //TRANSLIT) to mean "use charset of current locale".
2425 * localedef can now transliterate characters in strings which are not in
2426 the provided charmap. The information from the input locale is used.
2428 * Prelinking support was added for ELF targets. This requires additional
2429 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
2431 * Read-only stdio streams now use mmap to speed up operation by eliminating
2432 copying and buffer underflows. To use add 'm' to the mode string of
2433 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
2435 * The malloc functions were completely rewritten by Wolfram Gloger based
2436 on Doug Lea's malloc-2.7.0.c.
2438 * Isamu Hasegawa contributed a completely new and POSIX-conformant
2439 implementation of regex.
2441 * Bruno Haible upgraded the iconv and locale implementation to support
2444 * Contents of the LC_* and LANG environment variables in the CEN style are
2445 not recognized anymore. It never was used. Change by Ulrich Drepper.
2447 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
2448 thread-local storage (TLS) ABI on some platforms.
2449 Changes by Ulrich Drepper. SH support by Kaz Kojima.
2451 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
2452 EUC-JISX0213, and TSCII.
2454 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
2455 BSD-compatible interface for getting all network interface addresses.
2456 Implementation for IPv4 by Roland McGrath.
2458 * Loading of locale data is faster due to the introduction of a locale
2459 archive. Implemented by Roland McGrath and Ulrich Drepper.
2461 * Startup times are significantly reduced by not using exported functions
2462 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
2465 * Steven Munroe contributed a port to PowerPC64/Linux.
2469 * The Hurd now uses the GNU libio implementation of stdio rather than the
2470 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
2472 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
2473 with the same behavior as the Linux system call of the same name.
2477 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
2478 128-bit long double format.
2480 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
2481 IBM1161, and IBM1162 charsets.
2483 * Andreas Jaeger contributed a port to x86-64/Linux.
2485 * Peter Bruin contributed a port to PowerPC/Hurd.
2487 * libc functions using I/O streams now can handle wide-oriented streams
2490 * optimizations in the dynamic linker. Binaries created by recent binutils
2491 versions start up quicker due to reduced time spent on relocations.
2493 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
2497 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
2498 asinh, atanh, j0 for the 128-bit long double format.
2500 * Bruno Haible updated all the code handling Unicode in some form to
2501 support Unicode 3.1.
2503 * Speed of regex for single-byte locales is back to previous levels.
2504 Patch by Isamu Hasegawa.
2506 * Alpha, SPARC, and IA-64 now also using floating stacks.
2508 * Startup time of internationalized applications greatly improved through
2509 iconv cache. Use iconvconfig to generate the cache file.
2510 Contributed by Ulrich Drepper.
2512 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
2513 severe performance problems. Patch by David Mosberger.
2515 * The Hurd port got a lot more functionality like AIO, various stdio
2516 extensions, etc. Mainly done by Roland McGrath.
2518 * mtrace can now lookup symbols in shared libraries.
2522 * Intel's IA-64 math library is largely integrated. It provides fast and
2523 accurate implementatations for most basic and standard math functions
2524 in float, double, and long double format.
2526 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
2527 and asin for the 96-bit long double format and asin, log, tan for the
2528 128-bit long double format.
2530 * The beginning of a last-bit accurate math library by IBM Haifa were added.
2531 The basic double functions exist today. Contributed by Abraham Ziv
2532 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
2533 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
2535 * An asynchronous name lookup library was added. The interface is designed
2536 after POSIX AIO. The proposal was circulated beforehand to get comments.
2537 No negative ones came in. Implemented by Ulrich Drepper.
2539 * Port to S390/64bit contributed by Martin Schwidefsky
2540 <schwidefsky@de.ibm.com>.
2542 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
2543 of functions for Linux/IA-64.
2545 * The RPC code is now thread safe. Threads can now use the same service
2546 of different services at the same time. Patch by Eric Norum
2547 <eric.norum@usask.ca> with some help by Ulrich Drepper.
2549 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
2550 family of functions for Linux/S390.
2552 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
2553 of functions for Linux/x86.
2555 * Port to Linux/CRIS contributed by Axis Communications.
2559 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
2560 we can now check for namespace violations and missing declarations. The
2561 result is that almost all headers are now Unix-compliant (as defined in
2562 the upcoming XPG6). The negative side is that some programs might need
2563 corrections, too, if they depend on the incorrect form of the headers in
2564 previous versions which defined too many symbols and included too many
2567 * regex now handles multibyte character sets correctly.
2568 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
2570 * iconv (the program) does now conform to the upcoming XPG6 and handles
2571 charmaps. Instead of the charset names the path of charmaps can be
2572 provided and the conversion happens based on this data.
2573 Contributed by Ulrich Drepper.
2575 * The locale program now provides detailed information about the installed
2580 only lists the names of the supported locales
2584 provides details such as country, language, and codeset name.
2585 Contributed by Ulrich Drepper.
2589 * The gencat program now parses the input file according to the charset
2590 selected by the LC_CTYPE category. This is important for stateful
2591 character sets. To make generating catalogs easier there is a way
2592 to overwrite the charset selected by the locale: before the first
2593 message or $ quote line the catalog can contain a line like
2595 $ codeset=ISO-8859-2
2597 to select the charset (ISO-8859-2 in this case).
2599 Implemented by Shinya Hanataka and Ulrich Drepper.
2601 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
2602 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
2603 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
2605 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
2606 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
2608 * The LANGUAGE environment variable is now ignored unless the locale is
2609 changed from the default "C" locale.
2611 * The usual bug fixes.
2615 * Greg McGary added runtime support for bounds checking using gcc's
2616 new -fbounded-pointers option. ix86 target is complete. PowerPC
2619 * Thorsten Kukuk added secure mode support to nscd.
2621 * The Berkeley db libraries have been removed.
2623 Related, the nss_db module is now in a separate package since it
2624 obviously requires a database library being available.
2626 * Wide character I/O streams implemented by Ulrich Drepper.
2628 * Functions from the extended socket API added by Ulrich Drepper.
2630 * Functions feenableexcept and fedisableexcept to control the
2631 behaviour of individual exceptions have been added by Andreas Jaeger.
2633 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
2635 * The resolver code has been updated from bind 8.2.3-T5B which supports
2636 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
2639 This change could in some situations effect backward compatibility. Since
2640 now `_res' is a thread-local instead of a global variable, modifying it
2641 in one thread does not have any effect in other threads.
2643 The resolver library was also extended to allow IPv6 as the transport
2644 protocol for the requests. This work was done by Stig Venaas.
2646 * Compatibility code for K&R C compilers has been removed from the
2647 header files. A ISO C compiler is needed to use the library
2648 (conforming to either C89 or C99 standard).
2650 * Complete rewrite of the localedef program to support multibyte character
2651 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
2652 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
2653 Implemented by Ulrich Drepper.
2655 Bruno Haible significantly improved the generation and use of the data
2656 structures for the wide character tables.
2658 * Plural handling in gettext implemented by Ulrich Drepper.
2660 * The utmp daemon has been removed.
2662 * The port to MIPS-Linux has been finished by Andreas Jaeger.
2664 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
2667 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
2669 * POSIX barriers implemented by Kaz Kylheku.
2671 * POSIX spawn function family implemented by Ulrich Drepper.
2673 * POSIX spinlocks are now available.
2675 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
2677 * the configure option --enable-kernel=X.Y.Z allows to strip out
2678 compatibility for kernel versions before X.Y.Z. This is currently only
2679 implemented for Linux.
2681 * the sockaddr_in6 structure changed. The IPv6 working group added a new
2682 field sin6_scope_id. This means that all programs using IPv6 should be
2683 recompiled. Don't expect binary compatibility with previous glibc
2686 * various conversion modules for IBM character sets contributed by
2689 * IA-64 port by Jes Sorensen and HJ Lu.
2703 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
2705 * New xdr functions are added; some rpc functions are now 64bit clean.
2707 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
2709 * Fixed known incompatibilities with glibc 2.0.
2711 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
2713 * Optimized a number of functions (especially the ELF dynamic loader).
2715 * Update timezone data files.
2717 * lots of charmaps corrections
2719 * some new locale definitions and charmaps
2724 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
2725 conform to POSIX member type requirements. Symbol versions have been
2726 adjusted as needed within the library, and for direct use by applications,
2727 but there is potential for problems if third-party libraries use
2728 struct timeval as part of their interface. This does not present
2729 a problem for X and other "essential" system libraries.
2731 * An additional locale model to support C++ Standard Library locale
2732 model and probably more was implemented by Ulrich Drepper.
2734 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
2737 * Miles Bader provided the `argp' function family to support hierachical
2738 command line argument parsing, layered on top of getopt.
2740 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
2742 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
2745 * scanf recognizes the %a and %A format for scanning floating point numbers.
2747 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
2748 information and interfaces for the available integer types.
2750 * about 130 new math functions were added to implement the ISO C9x math
2753 * the new header <complex.h> contains definitions of the complex math
2754 functions from ISO C 9X.
2756 * the new header <tgmath.h> defines generic macros to use complex or
2757 real valued functions.
2759 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
2761 * Andreas Jaeger provided a test suite for the math library.
2763 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
2765 * Ulrich Drepper added character set conversion functions (iconv).
2767 * Optimized string functions have been added.
2769 * The localedata addon is now part of glibc.
2771 * An implementation of profiling shared libraries was added by Ulrich Drepper.
2773 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
2774 daemon for NSS (nscd).
2776 Missing a better place here are some numbers on improvements. Under
2777 Linux 2.1.125 un-tar-ing the kernel sources takes
2781 using local files 12.19s 6.88s 22.91s
2783 using NIS 13.92s 8.91s 26.34s
2785 using NIS & nscd 10.37s 7.34s 25.30s
2787 using NIS+ 27.57s 30.37s 640.46s
2789 using NIS+ & nscd 10.25s 7.83s 26.51s
2791 using NIS & old nscd [1] 13.83s 8.32s 29.60s
2793 Keep in mind that non-namelookup related operations dominate above times.
2794 It was just a common complain that using NIS+ unpacking the kernel is
2797 [1] The old nscd implementation is not available anymore since it was
2798 distributed with glibc up to version 2.0.98 and thus is now replaced.
2800 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
2802 * Mark Kettenis provided a Hesiod NSS module.
2804 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
2805 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
2807 * rcmd can now handle netgroups (Dick Streefland).
2809 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
2812 * Support for the IPv6 protocol has been added to the socket API, as per the
2813 latest draft standards.
2815 * Support for Linux 2.2 has been added.
2817 * Interface changes relative to the latest 2.0.x release:

3149 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3160 * inet_ntoa is thread-safe
3162 * updwtmp is moved from libutil to libc
3164 * rewrite of cbrt function
3166 * update of timezone data
3180 * add atoll function
3182 * fix complex problems in Berkeley DB code
3184 * fix math functions
3188 * fixed lots of header problems (especially Linux/GNU specific)
3190 * dynamic loader preserves all registers
3192 * Roland McGrath provided support for handling of auxiliary objects in
3193 the ELF dynamic loader.
3195 * support for parallel builds is improved
3199 * GNU extensions are no longer declared by default. To enable them you
3200 must define the macro `_GNU_SOURCE' in your program or compile with
3203 * The library has changed from using GNU ld symbol aliases to using weak
3204 symbols where available. The ELF object file format supports weak
3205 symbols; GNU ld also supports weak symbols in the a.out format. (There
3206 is also now support for other GNU ld extensions in ELF. Use the
3207 `--with-elf' option to configure to indicate you have ELF, and
3208 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
3209 of many files which contained only symbol aliases, reducing the size of
3210 the source and the compiled library; many other files were renamed to
3211 less cryptic names previously occupied by the symbol alias files.
3212 There is a new header file <elf.h> for programs which operate on
3213 files in the ELF format.
3215 * Converted to Autoconf version 2, so `configure' has more options.
3216 Run `configure --help' to see the details.
3218 * The library can now be configured to build profiling, highly-optimized
3219 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
3220 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
3221 `configure' enable building these extra libraries. The shared library is
3222 built by default when using both ELF and GNU ld. When shared libraries
3223 are enabled, the new library `-ldl' is available for arbitrary run-time
3224 loading of shared objects; its interface is defined in <dlfcn.h>. The
3225 new header file <link.h> gives access to the internals of the run-time
3226 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
3227 application of same name on other systems and it provides information
3228 about dynamically linked binaries.
3230 * The C library now provides the run-time support code for profiling
3231 executables compiled with `-pg'. Programs can control the profiling code
3232 through the interface in <sys/gmon.h>. The `gmon.out' files written by
3233 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
3234 the support for this file format was contributed by David Mosberger-Tang.
3236 * The math code has been replaced with a math library based on fdlibm from
3237 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
3238 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
3239 functions. The math functions now reside in a separate library, so
3240 programs using them will need to use `-lm' their linking commands.
3242 * John C. Bowman contributed optimized ix87 assembler inline functions.
3244 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
3245 mechanism similar to that found in Solaris 2. This is now used for the
3246 group, passwd, hosts, networks, services, protocols, rpc, ethers,
3247 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
3248 file controls what services are used for each individual database. This
3249 works by loading shared libraries with names specified in `nsswitch.conf',
3250 so service modules can be changed or added at any time without even
3251 relinking any program. Currently there are the file, db, and NIS based
3252 NSS services available.
3254 * The new functions `strtoq' and `strtouq' parse integer values from
3255 strings, like `strtol' and `strtoul', but they return `long long int' and
3256 `unsigned long long int' values, respectively (64-bit quantities).
3258 * The new functions `strtof' and `strtold' parse floating-point values from
3259 strings, like `strtod', but they return `float' and `long double' values,
3260 respectively (on some machines `double' and `long double' are the same).
3262 * Ulrich Drepper has contributed new implementations of the floating-point
3263 printing and reading code used in the `printf' family of functions and
3264 `strtod', `strtof', and `strtold'. These new functions are perfectly
3265 accurate, and much faster than the old ones.
3267 * The implementation of the POSIX locale model was completely rewritten by
3268 Ulrich Drepper. This includes the new programs `localedef' and `locale'
3269 to compile the POSIX locale definition.
3271 * The former dummy implementations of the strcoll and strxfrm function are
3272 now replaced by fully functional code contributed by Ulrich Drepper. The
3273 collation information comes from the POSIX locale definitions.
3275 * The new header <langinfo.h> defines an interface for accessing
3276 various locale-dependent data (using the locale chosen with `setlocale').
3278 * Ulrich Drepper has contributed a new suite of functions for operation on
3279 wide-character and multibyte-character strings, in <wchar.h>;
3280 and classification and case conversion of wide characters, in <wctype.h>.
3281 These new functions are conforming to the ISO C, Amendement 1 specification.
3283 * There is now a second implementation of the standard I/O library available.
3284 It comes from GNU libg++ as was written by Per Bothner, heavily modified
3285 by Hongjiu Lu and made thread safe by Ulrich Drepper.
3287 * You can now use positional parameter specifications in format strings
3288 for the `printf' and `scanf' families of functions. For example,
3289 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
3290 ``Number 6, Mr Jones''. This is mainly useful when providing different
3291 format strings for different languages, whose grammars may dictate
3292 different orderings of the values being printed. To support this
3293 feature, the interface for `register_printf_handler' has changed; see
3294 the header file <printf.h> for details.
3296 * The `printf' and `scanf' families of functions now understand a new
3297 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
3298 to group numbers as indicated by the locale; for `scanf' and friends, this
3299 says to accept as valid only a number with all the proper grouping
3300 separators in the right places. In the default "C" locale, numbers are
3301 not grouped; but locales for specific countries will define the usual
3302 conventions (i.e. separate thousands with `,' in the US locale).
3304 * The pgrp functions have been regularized, slightly incompatibly but much
3305 less confusingly. The core functions are now `getpgid' and `setpgid',
3306 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
3307 argument) and BSD `setpgrp' (identical to `setpgid') functions are
3308 provided for compatibility. There is no longer an incompatible `getpgrp'
3309 with an argument declared under _BSD_SOURCE; no BSD code uses it.
3311 * The new header file <fts.h> and suite of functions simplify programs that
3312 operate on directory trees. This code comes from 4.4 BSD.
3314 * The resolver code has been updated from the BIND 4.9.5-P1 release.
3315 Parts of the code were heavily modified by Ulrich Drepper to fit in the
3316 NSS scheme used in glibc.
3318 * There is a new malloc debugging hook `__memalign_hook'.
3320 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
3321 `unsigned int' in <sys/types.h>. These are for compatibility only and
3322 their use is discouraged.
3324 * The `-lmcheck' library to enable standard malloc debugging hooks is now
3325 done differently, so that it works even without GNU ld.
3327 * New function `euidaccess' checks allowed access to a file like `access',
3328 but using the effective IDs instead of the real IDs.
3330 * The time zone data files have been updated for the latest and greatest
3331 local time conventions of the countries of the world.
3333 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
3336 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
3337 for formatting floating-point numbers. They are provided only for
3338 compatibility; new programs should use `sprintf' instead. There are
3339 also equivalent function for the `long double' floating-point type and
3340 all functions also exist in a reentrant form.
3342 * The new auxiliary library `-lutil' from 4.4 BSD contains various
3343 functions for maintaining the login-record files (primarily of use to
3344 system programs such as `login'), and convenient functions for
3345 allocating and initializing a pseudo-terminal (pty) device.
3347 * Ulrich Drepper has contributed new support for System V style
3348 shared memory and IPC on systems that support it.
3350 * Ulrich Drepper has contributed several miscellaneous new functions found
3351 in System V: The `hsearch' family of functions provide an effective
3352 implementation of hash tables; `a64l' and `l64a' provide a very simple
3353 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
3356 * Ulrich Drepper has contributed new reentrant counterparts for the
3357 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
3359 * Ulrich Drepper has contributed new, highly-optimized versions of several
3360 string functions for the i486/Pentium family of processors.
3362 * Ulrich Drepper has updated the Linux-specific code, based largely
3363 on work done in Hongjiu Lu's version of GNU libc for Linux.
3364 The GNU library now supports Linux versions 2.0.10 and later,
3365 using the ELF object file format (i[3456]86-*-linux).
3367 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
3369 * David Mosberger-Tang and Richard Henderson have ported the C library
3370 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
3371 dynamic linking support for ELF/Alpha.
3373 * Richard Henderson contributed several Alpha optimized assembler function
3374 for arithmetic and string handling.
3376 * Ulrich Drepper has contributed a new set of message catalog functions to
3377 support multiple languages using the <libintl.h> interface, for use with
3378 his new package GNU gettext. Translation volunteers have contributed
3379 catalogs of the library's messages in Spanish, German, and Korean.
3381 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
3382 program and the `catgets' function for reading the catalog files it
3383 creates. (The <libintl.h> interface is preferred; we include the
3384 <nl_types.h> interface using `catgets' only for source compatibility with
3385 programs already written to use it.)
3387 * New header file <values.h> gives SVID-compatible names for <limits.h>
3390 * Various new macros, declarations, and small header files for compatibility
3393 * New function `group_member' is a convenient way to check if a process has
3394 a given effective group ID.
3396 * When using GCC 2.7 and later, the socket functions are now declared in a
3397 special way so that passing an argument of type `struct sockaddr_in *',
3398 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
3399 `struct sockaddr *' type, does not generate a type-clash warning.
3401 * New function `error' declared in header file <error.h> is a convenient
3402 function for printing error messages and optionally exiting; this is the
3403 canonical function used in GNU programs. The new functions `err', `warn',
3404 and friends in header file <err.h> are the canonical 4.4 BSD interface for
3405 doing the same thing.
3407 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
3408 POSIX.2 `glob' function to do ~ and {...} expansion.
3410 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
3411 `clearenv' which is used in POSIX.9 is also available.
3413 * New function `getsid' returns session ID number on systems that support it.
3415 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
3416 files <db.h> and <mpool.h> provide a rich set of functions for several
3417 types of simple databases stored in memory and in files, and <ndbm.h> is
3418 an old `ndbm'-compatible interface using the `db' functions. Link with
3419 `-ldb' to get these functions.
3421 * New macro `strdupa' copies a string like `strdup', but uses local stack
3422 space from `alloca' instead of dynamic heap space from `malloc'.
3424 * New function `strnlen' is like `strlen' but searches only a given maximum
3425 number of characters for the null terminator. `stpncpy', `strndup' and
3426 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
3429 * New function `statfs' in header <sys/statfs.h>.
3431 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
3432 provide convenient functions for operating on blocks of null-terminated
3435 * A new suite of functions in <utmp.h> handle all the details of reading
3436 and writing the utmp file.
3438 * An implementation of the NIS/YP(tm) based NSS service was contributed by
3441 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
3442 completely POSIX compliant and also implemented the extended functionality
3443 to handle alternate digit representation and alternate era date formats.
3445 * Ulrich Drepper provided an implementation of the `strptime' function
3446 defined in XPG4.2 which transforms a string into a `struct tm' value.
3448 * Paul Eggert provided the tzselect shell script as part of the timezone
3449 code. The shell script makes it easy to select the correct timezone
3452 * The implementation of the malloc family of functions is completely replaced
3453 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
3454 The implementation uses the mmap function (if available) and it is
3455 optimized for the use in multi threaded programs.
3457 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
3458 functions. This new functionality is usable by specifying a special
3459 salt string and it is compatible with implementation on *BSD systems.
3461 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
3462 `getsubopt' to handle second level command line options, `bsd_signal'
3463 to access BSD style `signal' functionality, the obsolete `regexp' style
3466 * the `lchown' function is available on system which support this
3469 * The implementation of the shadow password handling function was contributed
3472 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
3474 * POSIX.1g support was added. The <sys/select.h> header is available,
3475 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
3476 implementation of `getaddrinfo'.
3480 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
3482 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
3483 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
3485 * The new function `daemon' from 4.4 BSD is useful for server programs that
3486 want to put themselves in the background.
3488 * Joel Sherrill has contributed support for several standalone boards that
3489 run without an operating system.
3491 * `printf', `scanf' and friends now accept a `q' type modifier for long
3492 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
3494 * All of the code taken from BSD (notably most of the math and networking
3495 routines) has been updated from the BSD 4.4-Lite release.
3497 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
3499 * The new functions `getdomainname' and `setdomainname' fetch or change the
3500 YP/NIS domain name. These are system calls which exist on systems which
3503 * The time zone data files have been updated for the latest international
3506 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
3507 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
3511 * The C library now includes support for Sun RPC, from Sun's free
3512 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
3513 are included. (There is still no support for YP.)
3515 * Tom Quinn has contributed a port of the C library to SGI machines running
3516 Irix 4 (mips-sgi-irix4).
3518 * The new `lockf' function is a simplified interface to the locking
3519 facilities of `fcntl', included for compatibility.
3521 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
3523 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
3525 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
3528 * The error message printed by `assert' for a failed assertion now includes
3529 the name of the program (if using GNU ld) and the name of the calling
3530 function (with versions of GCC that support this).
3532 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
3534 * The library now includes the <sys/mman.h> header file and memory
3535 management functions `mmap', `munmap', `mprotect', `msync', and
3536 `madvise', on systems that support those facilities.
3538 * The interface for `mcheck' has changed slightly: the function called to
3539 abort the program when an allocation inconsistency is detected now takes
3540 an argument that indicates the type of failure. The new function
3541 `mprobe' lets you request a consistency check for a particular block at
3542 any time (checks are normally done only when you call `free' or `realloc'
3545 * It is now possible to easily cross-compile the C library, building on one
3546 system a library to run on another machine and/or operating system. All
3547 you need to do is set the variable `HOST_CC' in `configparms' to the
3548 native compiler for programs to run on the machine you are building on (a
3549 few generator programs are used on Unix systems); set `CC' to the
3552 * The new function `fexecve' (only implemented on the GNU system) executes
3553 a program file given a file descriptor already open on the file.
3557 * Brendan Kehoe has contributed most of a port to the DEC Alpha
3558 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
3560 * You can set the variable `libprefix' in `configparms' to specify a prefix
3561 to be prepended to installed library files; this makes it easy to install
3562 the GNU C library to be linked as `-lgnuc' or whatever.
3564 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
3565 copies a limited number of characters from a string, and returns the
3566 address of the last character written.
3568 * You no longer need to check for whether the installed `stddef.h' is
3569 compatible with the GNU C library. configure now checks for you.
3571 * You can now define a per-stream `fileno' function to convert the
3572 stream's cookie into an integral file descriptor.
3574 * ``malloc (0)'' no longer returns a null pointer. Instead, it
3575 allocates zero bytes of storage, and returns a unique pointer which
3576 you can pass to `realloc' or `free'. The behavior is undefined if
3577 you dereference this pointer.
3579 * The C library now runs on Sony NEWS m68k machines running either
3580 NewsOS 3 or NewsOS 4.
3582 * The new `syscall' function is a system-dependent primitive function
3583 for invoking system calls. It has the canonical behavior on Unix
3584 systems, including unreliable return values for some calls (such as
3585 `pipe', `fork' and `getppid').
3587 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
3588 to `EAGAIN', which is the preferred name. On systems whose kernels
3589 use two distinct codes, the C library now translates EWOULDBLOCK to
3590 EAGAIN in every system call function.
3594 * The GNU C Library Reference Manual is now distributed with the library.
3595 `make dvi' will produce a DVI file of the printed manual.
3596 `make info' will produce Info files that you can read on line using C-h i
3597 in Emacs or the `info' program.
3598 Please send comments on the manual to bug-glibc-manual@gnu.org.
3600 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
3602 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
3604 * Jason Merrill has contributed a port to the Sequent Symmetry running
3605 Dynix version 3 (i386-sequent-dynix).
3607 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
3608 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
3610 * New function `memory_warnings' lets you arrange to get warnings when
3611 malloc is running out of memory to allocate, like Emacs gives you.
3613 * The C library now contains the relocating allocator used in Emacs 19 for
3614 its editing buffers. This allocator (ralloc) minimizes allocation
3615 overhead and fragmentation by moving allocated regions around whenever it
3616 needs to. You always refer to a ralloc'd region with a "handle" (a
3617 pointer to a pointer--an object of type `void **').
3619 * There is a new `printf' format: `%m' gives you the string corresponding
3620 to the error code in `errno'.
3622 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
3623 or `%[' conversion, but instead of filling in a fixed-sized buffer you
3624 pass, the `a' modifier says to fill in a `char **' you pass with a
3627 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
3628 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
3629 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
3631 * `mkstemp' is a traditional Unix function to atomically create and open a
3632 uniquely-named temporary file.
3636 * The standard location for the file that says what the local timezone is
3637 has changed again. It is now `/usr/local/etc/localtime' (or more
3638 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
3640 * The distribution no longer contains any files with names longer than 14
3643 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
3644 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
3646 * New functions `ttyslot' and `syslog' from 4.4 BSD.
3650 * The configuration process has changed quite a bit. The `configure'
3651 script is now used just like the configuration scripts for other GNU
3652 packages. The `sysdeps' directory hierarchy is much rearranged.
3653 The file `INSTALL' explains the new scheme in detail.
3655 * The header files no longer need to be processed into ANSI C and
3656 traditional C versions. There is just one set of files to install, and
3657 it will work with ANSI or old C compilers (including `gcc -traditional').
3659 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
3660 MIPS DECStation running Ultrix 4.
3662 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
3663 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
3664 made itself into a shared library.
3666 * Yet further improved support for the i386, running 4.3 BSD-like systems
3667 (such as Mach 3 with the Unix single-server), or System V.
3669 * New function `strncasecmp' to do case-insensitive string comparison
3670 with limited length.
3672 * New function `strsep' is a reentrant alternative to `strtok'.
3674 * New functions `scandir' and `alphasort' for searching directories.
3676 * New function `setenv' is a better interface to `putenv'.
3678 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
3679 function for traversing a directory tree.
3681 * The GNU obstack package is now also part of the C library.
3682 The new function `open_obstack_stream' creates a stdio stream that
3683 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
3684 formatted output directly to an obstack.
3686 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
3687 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
3689 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
3691 * The new functions `strfry' and `memfrob' do mysterious and wonderful
3692 things to your strings.
3694 * There are some new test programs: test-fseek, testmb, and testrand.
3696 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
3697 These ports are not finished, but are a good starting place for really
3698 supporting those systems.
3700 * `/etc/localtime' is now the standard location for the file that says what
3701 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
3702 This follows the general principle that `/etc' is the place for all local
3703 configuration files.
3705 * The C library header files now use `extern "C"' when used by the C++
3706 compiler, so the C library should now work with C++ code.
3708 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
3709 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
3712 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
3713 function which uses the `merge sort' algorithm, and is said to be
3714 significantly faster than the old GNU `qsort' function. Merge sort is
3715 now the standard `qsort' function. The new algorithm can require a lot
3716 of temporary storage; so, the old sorting function is called when the
3717 required storage is not available.
3719 * The C library now includes Michael Glad's Ultra Fast Crypt, which
3720 provides the Unix `crypt' function, plus some other entry points.
3722 * The code and header files taken from 4.4 BSD have been updated with the
3723 latest files released from Berkeley.
