| 8 | Version 2.22 |
| 9 | |
| 10 | * The following bugs are resolved with this release: |
| 11 | |
| 12 | 438, 2981, 4719, 6544, 6792, 11216, 12836, 13028, 13064, 13151, 13152, |
| 13 | 14094, 14113, 14292, 14841, 14906, 14958, 15319, 15467, 15790, 15969, |
| 14 | 16159, 16339, 16350, 16351, 16352, 16353, 16361, 16512, 16526, 16538, |
| 15 | 16559, 16560, 16704, 16783, 16850, 17053, 17090, 17195, 17269, 17293, |
| 16 | 17322, 17403, 17475, 17523, 17542, 17569, 17581, 17588, 17596, 17620, |
| 17 | 17621, 17628, 17631, 17692, 17711, 17715, 17776, 17779, 17792, 17833, |
| 18 | 17836, 17841, 17912, 17916, 17930, 17932, 17944, 17949, 17964, 17965, |
| 19 | 17967, 17969, 17977, 17978, 17987, 17991, 17996, 17998, 17999, 18007, |
| 20 | 18019, 18020, 18029, 18030, 18032, 18034, 18036, 18038, 18039, 18042, |
| 21 | 18043, 18046, 18047, 18049, 18068, 18078, 18080, 18093, 18100, 18104, |
| 22 | 18110, 18111, 18116, 18125, 18128, 18134, 18138, 18185, 18196, 18197, |
| 23 | 18206, 18210, 18211, 18217, 18219, 18220, 18221, 18234, 18244, 18245, |
| 24 | 18247, 18287, 18319, 18324, 18333, 18346, 18371, 18383, 18397, 18400, |
| 25 | 18409, 18410, 18412, 18418, 18422, 18434, 18444, 18457, 18468, 18469, |
| 26 | 18470, 18479, 18483, 18495, 18496, 18497, 18498, 18502, 18507, 18508, |
| 27 | 18512, 18513, 18519, 18520, 18522, 18527, 18528, 18529, 18530, 18532, |
| 28 | 18533, 18534, 18536, 18539, 18540, 18542, 18544, 18545, 18546, 18547, |
| 29 | 18549, 18553, 18557, 18558, 18569, 18583, 18585, 18586, 18592, 18593, |
| 30 | 18594, 18602, 18612, 18613, 18619, 18633, 18635, 18641, 18643, 18648, |
| 31 | 18657, 18676, 18694, 18696. |
| 32 | |
| 33 | * Cache information can be queried via sysconf() function on s390 e.g. with |
| 34 | _SC_LEVEL1_ICACHE_SIZE as argument. |
| 35 | |
| 36 | * A buffer overflow in gethostbyname_r and related functions performing DNS |
| 37 | requests has been fixed. If the NSS functions were called with a |
| 38 | misaligned buffer, the buffer length change due to pointer alignment was |
| 39 | not taken into account. This could result in application crashes or, |
| 40 | potentially arbitrary code execution, using crafted, but syntactically |
| 41 | valid DNS responses. (CVE-2015-1781) |
| 42 | |
| 43 | * The time zone file parser has been made more robust against crafted time |
| 44 | zone files, avoiding heap buffer overflows related to the processing of |
| 45 | the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to |
| 46 | large time zone data files. Overly long time zone specifiers in the TZ |
| 47 | variable no longer result in stack overflows and crashes. |
| 48 | |
| 49 | * A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors |
| 50 | for LD and GD on x86 and x86-64, has been implemented. You will need |
| 51 | binutils-2.24 or later to enable this optimization. |
| 52 | |
| 53 | * Character encoding and ctype tables were updated to Unicode 7.0.0, using |
| 54 | new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red |
| 55 | Hat). These updates cause user visible changes, such as the fix for bug |
| 56 | 17998. |
| 57 | |
| 58 | * CVE-2014-8121 The NSS backends shared internal state between the getXXent |
| 59 | and getXXbyYY NSS calls for the same database, causing a denial-of-service |
| 60 | condition in some applications. |
| 61 | |
| 62 | * Added vector math library named libmvec with the following vectorized x86_64 |
| 63 | implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf, |
| 64 | pow, powf. |
| 65 | The library can be disabled with --disable-mathvec. Use of the functions is |
| 66 | enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0. |
| 67 | Shared library libmvec.so is linked in as needed when using -lm (no need to |
| 68 | specify -lmvec explicitly for not static builds). |
| 69 | Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information. |
| 70 | |
| 71 | * A new fmemopen implementation has been added with the goal of POSIX |
| 72 | compliance. The new implementation fixes the following long-standing |
| 73 | issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The |
| 74 | old implementation is still present for use be by existing binaries. |
| 75 | |
| 76 | * The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21 |
| 77 | releases. It has been fixed to match 2.19 and older, but binaries built |
| 78 | against 2.20 and 2.21 might need to be recompiled. See BZ#18694. |
| 79 | |
| 80 | * Port to Native Client running on ARMv7-A (--host=arm-nacl). |
| 81 | Contributed by Roland McGrath (Google). |
| 82 | |
| 83 | * The header <regexp.h> is deprecated, and will be removed in a future |
| 84 | release. Use of this header will trigger a deprecation warning. |
| 85 | Application developers should update their code to use <regex.h> instead. |
| 86 | |
| 87 | This header was formerly part of SUSv2, but was deprecated in 1997 and |
| 88 | removed from the standard in 2001. Also, the glibc implementation |
| 89 | leaks memory. See BZ#18681 for more details. |
| 90 | |
| 91 | Version 2.21 |
| 92 | |
| 93 | * The following bugs are resolved with this release: |
| 94 | |
| 95 | 6652, 10672, 12674, 12847, 12926, 13862, 14132, 14138, 14171, 14498, |
| 96 | 15215, 15378, 15884, 16009, 16418, 16191, 16469, 16576, 16617, 16618, |
| 97 | 16619, 16657, 16740, 16857, 17192, 17266, 17273, 17344, 17363, 17370, |
| 98 | 17371, 17411, 17460, 17475, 17485, 17501, 17506, 17508, 17522, 17555, |
| 99 | 17570, 17571, 17572, 17573, 17574, 17582, 17583, 17584, 17585, 17589, |
| 100 | 17594, 17601, 17608, 17616, 17625, 17630, 17633, 17634, 17635, 17647, |
| 101 | 17653, 17657, 17658, 17664, 17665, 17668, 17682, 17702, 17717, 17719, |
| 102 | 17722, 17723, 17724, 17725, 17732, 17733, 17744, 17745, 17746, 17747, |
| 103 | 17748, 17775, 17777, 17780, 17781, 17782, 17791, 17793, 17796, 17797, |
| 104 | 17801, 17803, 17806, 17834, 17844, 17848, 17868, 17869, 17870, 17885, |
| 105 | 17892. |
| 106 | |
| 107 | * CVE-2015-1472 CVE-2015-1473 Under certain conditions wscanf can allocate |
| 108 | too little memory for the to-be-scanned arguments and overflow the |
| 109 | allocated buffer. The implementation now correctly computes the required |
| 110 | buffer size when using malloc, and switches to malloc from alloca as |
| 111 | intended. |
| 112 | |
| 113 | * A new semaphore algorithm has been implemented in generic C code for all |
| 114 | machines. Previous custom assembly implementations of semaphore were |
| 115 | difficult to reason about or ensure that they were safe. The new version |
| 116 | of semaphore supports machines with 64-bit or 32-bit atomic operations. |
| 117 | The new semaphore algorithm is used by sem_init, sem_open, sem_post, |
| 118 | sem_wait, sem_timedwait, sem_trywait, and sem_getvalue. |
| 119 | |
| 120 | * Port to Altera Nios II has been contributed by Mentor Graphics. |
| 121 | |
| 122 | * Optimized strcpy, stpcpy, strncpy, stpncpy, strcmp, and strncmp |
| 123 | implementations for powerpc64/powerpc64le. |
| 124 | Implemented by Adhemerval Zanella (IBM). |
| 125 | |
| 126 | * Added support for TSX lock elision of pthread mutexes on powerpc32, powerpc64 |
| 127 | and powerpc64le. This may improve lock scaling of existing programs on |
| 128 | HTM capable systems. The lock elision code is only enabled with |
| 129 | --enable-lock-elision=yes. Also, the TSX lock elision implementation for |
| 130 | powerpc will issue a transaction abort on every syscall to avoid side |
| 131 | effects being visible outside transactions. |
| 132 | |
| 133 | * Optimized strcpy, stpcpy, strchrnul and strrchr implementations for |
| 134 | AArch64. Contributed by ARM Ltd. |
| 135 | |
| 136 | * i386 memcpy functions optimized with SSE2 unaligned load/store. |
| 137 | |
| 138 | * CVE-2104-7817 The wordexp function could ignore the WRDE_NOCMD flag |
| 139 | under certain input conditions resulting in the execution of a shell for |
| 140 | command substitution when the application did not request it. The |
| 141 | implementation now checks WRDE_NOCMD immediately before executing the |
| 142 | shell and returns the error WRDE_CMDSUB as expected. |
| 143 | |
| 144 | * CVE-2012-3406 printf-style functions could run into a stack overflow when |
| 145 | processing format strings with a large number of format specifiers. |
| 146 | |
| 147 | * CVE-2014-9402 The nss_dns implementation of getnetbyname could run into an |
| 148 | infinite loop if the DNS response contained a PTR record of an unexpected |
| 149 | format. |
| 150 | |
| 151 | * The minimum GCC version that can be used to build this version of the GNU |
| 152 | C Library is GCC 4.6. Older GCC versions, and non-GNU compilers, can |
| 153 | still be used to compile programs using the GNU C Library. |
| 154 | |
| 155 | * The GNU C Library is now built with -Werror by default. This can be |
| 156 | disabled by configuring with --disable-werror. |
| 157 | |
| 158 | * New locales: tu_IN, bh_IN, raj_IN, ce_RU. |
| 159 | |
| 160 | * The obsolete sigvec function has been removed. This was the original |
| 161 | 4.2BSD interface that inspired the POSIX.1 sigaction interface, which |
| 162 | programs have been using instead for about 25 years. Of course, ABI |
| 163 | compatibility for old binaries using sigvec remains intact. |
| 164 | |
| 165 | * Merged gettext 0.19.3 into the intl subdirectory. This fixes building |
| 166 | with newer versions of bison. |
| 167 | |
| 168 | * Support for MIPS o32 FPXX, FP64A and FP64 ABI Extensions. |
| 169 | The original MIPS o32 hard-float ABI requires an FPU where double-precision |
| 170 | registers overlay two consecutive single-precision registers. MIPS32R2 |
| 171 | introduced a new FPU mode (FR=1) where double-precision registers extend the |
| 172 | corresponding single-precision registers which is incompatible with the |
| 173 | o32 hard-float ABI. The MIPS SIMD ASE and the MIPSR6 architecture both |
| 174 | require the use of FR=1 making a transition necessary. New o32 ABI |
| 175 | extensions enable users to migrate over time from the original o32 ABI |
| 176 | through to the updated o32 FP64 ABI. To achieve this the dynamic linker now |
| 177 | tracks the ABI of any loaded object and verifies that new objects are |
| 178 | compatible. Mode transitions will also be requested as required and |
| 179 | unsupportable objects will be rejected. The ABI checks include both soft and |
| 180 | hard float ABIs for o32, n32 and n64. |
| 181 | |
| 182 | GCC 5 with GNU binutils 2.25 onwards: |
| 183 | It is strongly recommended that all o32 system libraries are built using the |
| 184 | new o32 FPXX ABI (-mfpxx) to facilitate the transition as this is compatible |
| 185 | with the original and all new o32 ABI extensions. Configure a MIPS GCC |
| 186 | compiler using --with-fp-32=xx to set this by default. |
| 187 | |
| 188 | Version 2.20 |
| 189 | |
| 190 | * The following bugs are resolved with this release: |
| 191 | |
| 192 | 6804, 9894, 11505, 12994, 13347, 13651, 14308, 14770, 15119, 15132, 15347, |
| 193 | 15514, 15698, 15804, 15894, 15946, 16002, 16064, 16095, 16194, 16198, |
| 194 | 16275, 16284, 16287, 16315, 16348, 16349, 16354, 16357, 16362, 16447, |
| 195 | 16516, 16532, 16539, 16545, 16561, 16562, 16564, 16574, 16599, 16600, |
| 196 | 16609, 16610, 16611, 16613, 16619, 16623, 16629, 16632, 16634, 16639, |
| 197 | 16642, 16648, 16649, 16670, 16674, 16677, 16680, 16681, 16683, 16689, |
| 198 | 16695, 16701, 16706, 16707, 16712, 16713, 16714, 16724, 16731, 16739, |
| 199 | 16740, 16743, 16754, 16758, 16759, 16760, 16770, 16786, 16789, 16791, |
| 200 | 16796, 16799, 16800, 16815, 16823, 16824, 16831, 16838, 16839, 16849, |
| 201 | 16854, 16876, 16877, 16878, 16882, 16885, 16888, 16890, 16892, 16912, |
| 202 | 16915, 16916, 16917, 16918, 16922, 16927, 16928, 16932, 16943, 16958, |
| 203 | 16965, 16966, 16967, 16977, 16978, 16984, 16990, 16996, 17009, 17022, |
| 204 | 17031, 17042, 17048, 17050, 17058, 17061, 17062, 17069, 17075, 17078, |
| 205 | 17079, 17084, 17086, 17088, 17092, 17097, 17125, 17135, 17137, 17150, |
| 206 | 17153, 17187, 17213, 17259, 17261, 17262, 17263, 17319, 17325, 17354. |
| 207 | |
| 208 | * Reverted change of ABI data structures for s390 and s390x: |
| 209 | On s390 and s390x the size of struct ucontext and jmp_buf was increased in |
| 210 | 2.19. This change is reverted in 2.20. The introduced 2.19 symbol versions |
| 211 | of getcontext, setjmp, _setjmp, __sigsetjmp, longjmp, _longjmp, siglongjmp |
| 212 | are preserved pointing straight to the same implementation as the old ones. |
| 213 | Given that, new callers will simply provide a too-big buffer to these |
| 214 | functions. Any applications/libraries out there that embed jmp_buf or |
| 215 | ucontext_t in an ABI-relevant data structure that have already been rebuilt |
| 216 | against 2.19 headers will have to rebuilt again. This is necessary in any |
| 217 | case to revert the breakage in their ABI caused by the glibc change. |
| 218 | |
| 219 | * Support for file description locks is added to systems running the |
| 220 | Linux kernel. The standard file locking interfaces are extended to |
| 221 | operate on file descriptions, not file descriptors, via the use of |
| 222 | F_OFD_GETLK, F_OFD_SETLK, and F_OFD_SETLKW. File description locks |
| 223 | are associated with an open file instead of a process. |
| 224 | |
| 225 | * Optimized strchr implementation for AArch64. Contributed by ARM Ltd. |
| 226 | |
| 227 | * The minimum Linux kernel version that this version of the GNU C Library |
| 228 | can be used with is 2.6.32. |
| 229 | |
| 230 | * Running the testsuite no longer terminates as soon as a test fails. |
| 231 | Instead, a file tests.sum (xtests.sum from "make xcheck") is generated, |
| 232 | with PASS or FAIL lines for individual tests. A summary of the results is |
| 233 | printed, including a list of failing lists, and "make check" exits with |
| 234 | error status if there were any unexpected failures. "make check |
| 235 | stop-on-test-failure=y" may be used to keep the old behavior. |
| 236 | |
| 237 | * The am33 port, which had not worked for several years, has been removed |
| 238 | from ports. |
| 239 | |
| 240 | * The _BSD_SOURCE and _SVID_SOURCE feature test macros are no longer |
| 241 | supported; they now act the same as _DEFAULT_SOURCE (but generate a |
| 242 | warning). Except for cases where _BSD_SOURCE enabled BSD interfaces that |
| 243 | conflicted with POSIX (support for which was removed in 2.19), the |
| 244 | interfaces those macros enabled remain available when compiling with |
| 245 | _GNU_SOURCE defined, with _DEFAULT_SOURCE defined, or without any feature |
| 246 | test macros defined. |
| 247 | |
| 248 | * Optimized strcmp implementation for ARMv7. Contributed by ARM Ltd. |
| 249 | |
| 250 | * Added support for TX lock elision of pthread mutexes on s390 and s390x. |
| 251 | This may improve lock scaling of existing programs on TX capable systems. |
| 252 | The lock elision code is only built with --enable-lock-elision=yes and |
| 253 | then requires a GCC version supporting the TX builtins. With lock elision |
| 254 | default mutexes are elided via __builtin_tbegin, if the cpu supports |
| 255 | transactions. By default lock elision is not enabled and the elision code |
| 256 | is not built. |
| 257 | |
| 258 | * CVE-2014-4043 The posix_spawn_file_actions_addopen implementation did not |
| 259 | copy the path argument. This allowed programs to cause posix_spawn to |
| 260 | deference a dangling pointer, or use an unexpected pathname argument if |
| 261 | the string was modified after the posix_spawn_file_actions_addopen |
| 262 | invocation. |
| 263 | |
| 264 | * All supported architectures now use the main glibc sysdeps directory |
| 265 | instead of some being in a separate "ports" directory (which was |
| 266 | distributed separately before glibc 2.17). |
| 267 | |
| 268 | * The NPTL implementation of POSIX pthreads is no longer an "add-on". |
| 269 | On configurations that support it (all Linux configurations), it's now |
| 270 | used regardless of the --enable-add-ons switch to configure. It is no |
| 271 | longer possible to build such configurations without pthreads support. |
| 272 | |
| 273 | * Locale names, including those obtained from environment variables (LANG |
| 274 | and the LC_* variables), are more tightly checked for proper syntax. |
| 275 | setlocale will now fail (with EINVAL) for locale names that are overly |
| 276 | long, contain slashes without starting with a slash, or contain ".." path |
| 277 | components. (CVE-2014-0475) Previously, some valid locale names were |
| 278 | silently replaced with the "C" locale when running in AT_SECURE mode |
| 279 | (e.g., in a SUID program). This is no longer necessary because of the |
| 280 | additional checks. |
| 281 | |
| 282 | * On x86-64, the dynamic linker's lazy-binding support is now compatible |
| 283 | with application code using Intel MPX instructions. (With all previous |
| 284 | versions, the MPX register state could be clobbered when making calls |
| 285 | into or out of a shared library.) Note that while the new dynamic |
| 286 | linker is compatible with all known x86 hardware whether or not it |
| 287 | supports Intel MPX, some x86 instruction-set emulators might fail to |
| 288 | handle the new instruction encodings. This is known to affect Valgrind |
| 289 | versions up through 3.9 (but will be fixed in the forthcoming 3.10 |
| 290 | release), and might affect other tools that do instruction emulation. |
| 291 | |
| 292 | * Support for loadable gconv transliteration modules has been removed. |
| 293 | The support for transliteration modules has been non-functional for |
| 294 | over a decade, and the removal is prompted by security defects. The |
| 295 | normal gconv conversion modules are still supported. Transliteration |
| 296 | with //TRANSLIT is still possible, and the //IGNORE specifier |
| 297 | continues to be supported. (CVE-2014-5119) |
| 298 | |
| 299 | * Decoding a crafted input sequence in the character sets IBM933, IBM935, |
| 300 | IBM937, IBM939, IBM1364 could result in an out-of-bounds array read, |
| 301 | resulting a denial-of-service security vulnerability in applications which |
| 302 | use functions related to iconv. (CVE-2014-6040) |
| 303 | |
| 304 | Version 2.19 |
| 305 | |
| 306 | * The following bugs are resolved with this release: |

| 325 | 16431, 16453, 16474, 16506, 16510, 16529 |
| 326 | |
| 327 | * Slovenian translations for glibc messages have been contributed by the |
| 328 | Translation Project's Slovenian team of translators. |
| 329 | |
| 330 | * The public headers no longer use __unused nor __block. This change is to |
| 331 | support compiling programs that are derived from BSD sources and use |
| 332 | __unused internally, and to support compiling with Clang's -fblock |
| 333 | extension which uses __block. |
| 334 | |
| 335 | * CVE-2012-4412 The strcoll implementation caches indices and rules for |
| 336 | large collation sequences to optimize multiple passes. This cache |
| 337 | computation may overflow for large collation sequences and may cause a |
| 338 | stack or buffer overflow. This is now fixed to use a slower algorithm |
| 339 | which does not use a cache if there is an integer overflow. |
| 340 | |
| 341 | * CVE-2012-4424 The strcoll implementation uses malloc to cache indices and |
| 342 | rules for large collation sequences to optimize multiple passes and falls |
| 343 | back to alloca if malloc fails, resulting in a possible stack overflow. |
| 344 | The implementation now falls back to an uncached collation sequence lookup |
| 345 | if malloc fails. |
| 346 | |
| 347 | * CVE-2013-4788 The pointer guard used for pointer mangling was not |
| 348 | initialized for static applications resulting in the security feature |
| 349 | being disabled. The pointer guard is now correctly initialized to a |
| 350 | random value for static applications. Existing static applications need |
| 351 | to be recompiled to take advantage of the fix (bug 15754). |
| 352 | |
| 353 | * CVE-2013-4237 The readdir_r function could write more than NAME_MAX bytes |
| 354 | to the d_name member of struct dirent, or omit the terminating NUL |
| 355 | character. (Bugzilla #14699). |
| 356 | |
| 357 | * CVE-2013-4332 The pvalloc, valloc, memalign, posix_memalign and |
| 358 | aligned_alloc functions could allocate too few bytes or corrupt the |
| 359 | heap when passed very large allocation size values (Bugzilla #15855, |
| 360 | #15856, #15857). |
| 361 | |
| 362 | * CVE-2013-4458 Stack overflow in getaddrinfo with large number of results |
| 363 | for AF_INET6 has been fixed (Bugzilla #16072). |
| 364 | |
| 365 | * New locales: ak_GH, anp_IN, ar_SS, cmn_TW, hak_TW, lzh_TW, nan_TW, pap_AW, |
| 366 | pap_CW, quz_PE, the_NP. |
| 367 | |
| 368 | * Substantially revised locales: gd_GB, ht_HT |
| 369 | |
| 370 | * The LC_ADDRESS field was updated to support country_car for almost all |
| 371 | supported locales. |
| 372 | |
| 373 | * ISO 1427 definitions were updated. |
| 374 | |
| 375 | * ISO 3166 definitions were updated. |
| 376 | |
| 377 | * The localedef utility now supports --big-endian and --little-endian |
| 378 | command-line options to generate locales for a different system from that |
| 379 | for which the C library was built. |
| 380 | |
| 381 | * Binary locale files now only depend on the endianness of the system for |
| 382 | which they are generated and not on other properties of that system. As a |
| 383 | consequence, binary files generated with new localedef may be incompatible |
| 384 | with old versions of the GNU C Library, and binary files generated with |
| 385 | old localedef may be incompatible with this version of the GNU C Library, |
| 386 | in the following circumstances: |
| 387 | |
| 388 | + Locale files may be incompatible on m68k systems. |
| 389 | |
| 390 | + Locale archive files (but not separate files for individual locales) may |
| 391 | be incompatible on systems where plain "char" is signed. |
| 392 | |
| 393 | * The configure option --disable-versioning has been removed. Builds with |
| 394 | --disable-versioning had not worked for several years. |
| 395 | |
| 396 | * ISO 639 definitions were updated for Chiga (cgg) and Chinese (gan, hak, czh, |
| 397 | cjy, lzh, cmn, mnp, cdo, czo, cpx, wuu, hsn, yue). |
| 398 | |
| 399 | * SystemTap probes for malloc have been introduced. |
| 400 | |
| 401 | * SystemTap probes for slow multiple precision fallback paths of |
| 402 | transcendental functions have been introduced. |
| 403 | |
| 404 | * Support for powerpc64le has been added. |
| 405 | |
| 406 | * The soft-float powerpc port now supports e500 processors. |
| 407 | |
| 408 | * Support for STT_GNU_IFUNC symbols added for ppc32/power4+ and ppc64. |
| 409 | |
| 410 | * A new feature test macro _DEFAULT_SOURCE is available to enable the same |
| 411 | set of header declarations that are enabled by default, even when other |
| 412 | feature test macros or compiler options such as -std=c99 would otherwise |
| 413 | disable some of those declarations. |
| 414 | |
| 415 | * The _BSD_SOURCE feature test macro no longer enables BSD interfaces that |
| 416 | conflict with POSIX. The libbsd-compat library (which was a dummy library |
| 417 | that did nothing) has also been removed. |
| 418 | |
| 419 | * Preliminary documentation about Multi-Thread, Async-Signal and |
| 420 | Async-Cancel Safety has been added. |
| 421 | |
| 422 | * Change of ABI data structures for s390 and s390x: |
| 423 | On s390 and s390x the size of struct ucontext and jmp_buf was increased to |
| 424 | allow for future hardware extensions. All library functions that accept or |
| 425 | return these structures were versioned in order to provide backwards |
| 426 | compatibility with existing code. However, not all cases can be handled |
| 427 | with interface versioning. If an application embeds either structure into |
| 428 | another structure and that structure is passed to another compilation unit |
| 429 | which expects the newer larger-sized object then any access to the new |
| 430 | fields will result in undefined behaviour. Similarly any access to fields |
| 431 | that were moved by the enlarging of the structures will cause undefined |
| 432 | behaviour. To fix the undefined behaviour all objects that are part of the |
| 433 | final in-memory image must agree on the size of structures, and this may |
| 434 | require recompilation. |
| 435 | |
| 436 | Version 2.18 |
| 437 | |
| 438 | * The following bugs are resolved with this release: |
| 439 | |
| 440 | 2546, 2560, 5159, 6809, 7006, 10060, 10062, 10283, 10357, 10686, 11120, |
| 441 | 11561, 12310, 12387, 12492, 12515, 12723, 13550, 13889, 13951, 13988, |
| 442 | 14142, 14176, 14200, 14256, 14280, 14293, 14317, 14327, 14478, 14496, |
| 443 | 14582, 14686, 14812, 14888, 14894, 14907, 14908, 14909, 14920, 14952, |
| 444 | 14964, 14981, 14982, 14985, 14991, 14994, 14996, 15000, 15003, 15006, |
| 445 | 15007, 15014, 15020, 15022, 15023, 15036, 15054, 15055, 15062, 15078, |
| 446 | 15084, 15085, 15086, 15100, 15160, 15214, 15221, 15232, 15234, 15283, |
| 447 | 15285, 15287, 15304, 15305, 15307, 15309, 15327, 15330, 15335, 15336, |
| 448 | 15337, 15339, 15342, 15346, 15359, 15361, 15366, 15380, 15381, 15394, |
| 449 | 15395, 15405, 15406, 15409, 15416, 15418, 15419, 15423, 15424, 15426, |
| 450 | 15429, 15431, 15432, 15441, 15442, 15448, 15465, 15480, 15485, 15488, |
| 451 | 15490, 15492, 15493, 15497, 15506, 15529, 15536, 15553, 15577, 15583, |
| 452 | 15618, 15627, 15631, 15654, 15655, 15666, 15667, 15674, 15711, 15755, |
| 453 | 15759. |
| 454 | |
| 455 | * CVE-2013-2207 Incorrectly granting access to another user's pseudo-terminal |
| 456 | has been fixed by disabling the use of pt_chown (Bugzilla #15755). |
| 457 | Distributions can re-enable building and using pt_chown via the new configure |
| 458 | option `--enable-pt_chown'. Enabling the use of pt_chown carries with it |
| 459 | considerable security risks and should only be used if the distribution |
| 460 | understands and accepts the risks. |
| 461 | |
| 462 | * CVE-2013-0242 Buffer overrun in regexp matcher has been fixed (Bugzilla |
| 463 | #15078). |
| 464 | |
| 465 | * CVE-2013-1914 Stack overflow in getaddrinfo with many results has been |
| 466 | fixed (Bugzilla #15330). |
| 467 | |
| 468 | * Add support for calling C++11 thread_local object destructors on thread |
| 469 | and program exit. This needs compiler support for offloading C++11 |
| 470 | destructor calls to glibc. |
| 471 | |
| 472 | * Improved worst case performance of libm functions with double inputs and |
| 473 | output. |
| 474 | |
| 475 | * Support for priority inherited mutexes in pthread condition variables on |
| 476 | non-x86 architectures. |
| 477 | |
| 478 | * Port to Xilinx MicroBlaze contributed by David Holsgrove. |
| 479 | |
| 480 | * Optimized string functions for AArch64. Implemented by Marcus Shawcroft. |
| 481 | |
| 482 | * Optimized string functions for ARM. Implemented by Will Newton and |
| 483 | Richard Henderson. |
| 484 | |
| 485 | * Optimized libm functions for SPARC. Implemented by David S. Miller. |
| 486 | |
| 487 | * Support for building more of ARM glibc as Thumb-2 code. Implemented by |
| 488 | Richard Henderson. |
| 489 | |
| 490 | * Support for building most of MIPS glibc as MIPS16 code. Implemented by |
| 491 | Chung-Lin Tang, Maciej W. Rozycki and Maxim Kuvyrkov. |
| 492 | |
| 493 | * Added a benchmark framework to track performance of functions in glibc. |
| 494 | |
| 495 | * New <math.h> macro named issignaling to check for a signaling NaN (sNaN). |
| 496 | It is based on draft TS 18661 and currently enabled as a GNU extension. |
| 497 | |
| 498 | * On Linux, the clock function now uses the clock_gettime system call |
| 499 | for improved precision, rather than old times system call. |
| 500 | |
| 501 | * Added support for version-3 tz format files. This is needed when using |
| 502 | the tz database release 2013e or later, and affects a few unusual cases -- |
| 503 | currently only TZ='America/Godthab' for time stamps after 2037. |
| 504 | |
| 505 | * Added new API functions pthread_getattr_default_np and |
| 506 | pthread_setattr_default_np to get and set the default pthread |
| 507 | attributes of a process. |
| 508 | |
| 509 | * Added support for TSX lock elision for pthread mutexes on i386 and x86-64. |
| 510 | This may improve lock scaling of existing programs on TSX capable systems. |
| 511 | When the --enable-lock-elision=yes parameter is specified at configure |
| 512 | time lock elision will be enabled by default for all PTHREAD_MUTEX_DEFAULT |
| 513 | mutexes. |
| 514 | |
| 515 | * Support added for AT_HWCAP2 (to coincide with Linux kernel 3.10 |
| 516 | availability). Implemented by Ryan S. Arnold. |
| 517 | |
| 518 | * Support added for POWER8 platform. Implemented by Ryan S. Arnold. |
| 519 | |
| 520 | Version 2.17 |
| 521 | |
| 522 | * The following bugs are resolved with this release: |
| 523 | |
| 524 | 1349, 3439, 3479, 3665, 5044, 5246, 5298, 5400, 6530, 6677, 6778, 6808, |
| 525 | 9685, 9914, 10014, 10038, 10114, 10191, 10631, 10873, 11438, 11607, 11638, |

| 536 | 14805, 14807, 14811, 14815, 14821, 14822, 14824, 14828, 14831, 14833, |
| 537 | 14835, 14838, 14856, 14863, 14865, 14866, 14868, 14869, 14871, 14872, |
| 538 | 14879, 14889, 14893, 14898, 14914. |
| 539 | |
| 540 | * Optimization of memcpy for MIPS. |
| 541 | |
| 542 | * CVE-2011-4609 svc_run() produces high cpu usage when accept fails with |
| 543 | EMFILE has been fixed (Bugzilla #14889). |
| 544 | |
| 545 | * The add-on ports collection is now distributed in the "ports" subdirectory |
| 546 | of the main GNU C Library distribution, rather than separately. |
| 547 | |
| 548 | * Port to ARM AArch64 contributed by Linaro. |
| 549 | |
| 550 | * Support for STT_GNU_IFUNC symbols added for s390 and s390x. |
| 551 | Optimized versions of memcpy, memset, and memcmp added for System z10 and |
| 552 | zEnterprise z196. |
| 553 | Implemented by Andreas Krebbel. |
| 554 | |
| 555 | * The new function secure_getenv allows secure access to the environment, |
| 556 | returning NULL if running in a SUID/SGID process. This function replaces |
| 557 | the internal function __secure_getenv. |
| 558 | |
| 559 | * SystemTap static probes have been added into the dynamic linker. |
| 560 | Implemented by Gary Benson. |
| 561 | |
| 562 | * Optimizations of string functions strstr, strcasestr and memmem. |
| 563 | Implemented by Maxim Kuvyrkov. |
| 564 | |
| 565 | * The minimum Linux kernel version that this version of the GNU C Library |
| 566 | can be used with is 2.6.16. |
| 567 | |
| 568 | * Optimizations of string functions memchr, wcschr, wcscpy, and wcsrchr for |
| 569 | powerpc POWER7. Implemented by Will Schmidt. |
| 570 | |
| 571 | * New configure option --disable-nscd builds the C library such that it |
| 572 | never attempts to contact the Name Service Caching Daemon (nscd). |
| 573 | New configure option --disable-build-nscd avoids building nscd itself; |
| 574 | this is the default if --disable-nscd is used. |
| 575 | |
| 576 | * Improved support for cross-compilation, including cross-testing and |
| 577 | bootstrap builds without a previously built glibc. |
| 578 | |
| 579 | * Several testsuite tests are now able to test multiple IFUNC variants of an |
| 580 | interface, rather than just testing the one that would be chooen by |
| 581 | default. |
| 582 | |
| 583 | * New configure options --with-bugurl and --with-pkgversion, for |
| 584 | distributors to use to embed their bug-reporting and package version |
| 585 | information in --help and --version output. |
| 586 | |
| 587 | * The ttyname and ttyname_r functions on Linux now fall back to searching for |
| 588 | the tty file descriptor in /dev/pts or /dev if /proc is not available. This |
| 589 | allows creation of chroots without the procfs mounted on /proc. |
| 590 | |
| 591 | * The `crypt' function now fails if passed salt bytes that violate the |
| 592 | specification for those values. On Linux, the `crypt' function will |
| 593 | consult /proc/sys/crypto/fips_enabled to determine if "FIPS mode" is |
| 594 | enabled, and fail on encrypted strings using the MD5 or DES algorithm |
| 595 | when the mode is enabled. |
| 596 | |
| 597 | * The `clock_*' suite of functions (declared in <time.h>) is now available |
| 598 | directly in the main C library. Previously it was necessary to link with |
| 599 | -lrt to use these functions. This change has the effect that a |
| 600 | single-threaded program that uses a function such as `clock_gettime' (and |
| 601 | is not linked with -lrt) will no longer implicitly load the pthreads |
| 602 | library at runtime and so will not suffer the overheads associated with |
| 603 | multi-thread support in other code such as the C++ runtime library. |
| 604 | |
| 605 | * New locales: ayc_PE, doi_IN, ia_FR, mni_IN, nhn_MX, niu_NU, niu_NZ, |
| 606 | sat_IN, and szl_PL. |
| 607 | |
| 608 | Version 2.16 |
| 609 | |
| 610 | * The following bugs are resolved with this release: |
| 611 | |
| 612 | 174, 208, 350, 369, 411, 706, 766, 887, 2074, 2541, 2547, 2548, 2550, |

| 627 | 13895, 13908, 13910, 13911, 13912, 13913, 13914, 13915, 13916, 13917, |
| 628 | 13918, 13919, 13920, 13921, 13922, 13923, 13924, 13926, 13927, 13928, |
| 629 | 13938, 13941, 13942, 13954, 13955, 13956, 13963, 13967, 13968, 13970, |
| 630 | 13973, 13979, 13983, 13986, 13996, 14012, 14027, 14033, 14034, 14036, |
| 631 | 14040, 14043, 14044, 14048, 14049, 14050, 14053, 14055, 14059, 14064, |
| 632 | 14075, 14080, 14083, 14103, 14104, 14109, 14112, 14117, 14122, 14123, |
| 633 | 14134, 14153, 14183, 14188, 14199, 14210, 14218, 14229, 14241, 14273, |
| 634 | 14277, 14278. |
| 635 | |
| 636 | * Support for the x32 ABI on x86-64 added. The x32 target is selected by |
| 637 | configuring glibc with: |
| 638 | BUILD_CC='gcc' CC='gcc -mx32' CXX='g++ -mx32' |
| 639 | Visit <http://sites.google.com/site/x32abi/> for more x32 ABI info. |
| 640 | Implemented by H.J. Lu. |
| 641 | |
| 642 | * ISO C11 support: |
| 643 | |
| 644 | + define static_assert |
| 645 | |
| 646 | + do not declare gets |
| 647 | |
| 648 | + declare at_quick_exit and quick_exit also for ISO C11 |
| 649 | |
| 650 | + aligned_alloc. NB: The code is deliberately allows the size parameter |
| 651 | to not be a multiple of the alignment. This is a moronic requirement |
| 652 | in the standard but it is only a requirement on the caller, not the |
| 653 | implementation. |
| 654 | |
| 655 | + timespec_get added |
| 656 | |
| 657 | + uchar.h support added |
| 658 | |
| 659 | + CMPLX, CMPLXF, CMPLXL added |
| 660 | |
| 661 | Implemented by Ulrich Drepper. |
| 662 | |
| 663 | * Support for the IA-64 has been moved to ports. |
| 664 | |
| 665 | * Remove support for anything but ELF binary format |
| 666 | |
| 667 | * Checking versions of poll, ppoll added. |
| 668 | Implemented by Ulrich Drepper. |
| 669 | |
| 670 | * More generic and 64-bit performance optimizations to math functions. |
| 671 | Implemented by Ulrich Drepper. |
| 672 | |
| 673 | * New configure option --enable-obsolete-rpc makes the deprecated RPC |
| 674 | headers and functions available at compile time as they were before |
| 675 | version 2.14. This option will be removed at some time in the future |
| 676 | after the TI-RPC library becomes fully sufficient for the needs of |
| 677 | existing applications. |
| 678 | |
| 679 | * Compatibility code for Linux kernel versions before 2.4 has been removed. |
| 680 | Note that glibc is not expected to work with any Linux kernel version |
| 681 | before 2.6. |
| 682 | |
| 683 | * New header <sys/auxv.h> and function getauxval allowing easy access to |
| 684 | the AT_* key-value pairs passed from the Linux kernel. The header also |
| 685 | defines the HWCAP_* bits associated with the AT_HWCAP key. |
| 686 | |
| 687 | * New locales: mag_IN |
| 688 | |
| 689 | * New configure option --enable-systemtap builds SystemTap static probes |
| 690 | into libc for setjmp and longjmp and into libpthread for various operations. |
| 691 | So far the setjmp/longjmp probes and some of the libpthread probes are |
| 692 | provided only for i*86 and x86_64. |
| 693 | Implemented by Roland McGrath and Rayson Ho. |
| 694 | |
| 695 | * Optimized expf for x86-32 and x86-64. Implemented by Liubov Dmitrieva. |
| 696 | |
| 697 | * More optimized functions for PowerPC. Implemented by Adhemerval Zanella |
| 698 | and Will Schmidt. |
| 699 | |
| 700 | * More optimized functions for SPARC. Implemented by David S. Miller. |
| 701 | |
| 702 | * Improved support for cross-compilation, especially bootstrap builds |
| 703 | without a previously built glibc. |
| 704 | |
| 705 | * Ports for the TILE-Gx and TILEPro families of processors. Contributed by |
| 706 | Chris Metcalf from Tilera. |
| 707 | |
| 708 | * Support for the old ARM ABI has been removed from ports. Only the EABI is |
| 709 | now supported for ARM processors. |
| 710 | |
| 711 | * The hard-float variant of the ARM EABI now uses /lib/ld-linux-armhf.so.3 |
| 712 | as the name of the dynamic linker, to distinguish it from the |
| 713 | /lib/ld-linux.so.3 dynamic linker used for the base EABI. |
| 714 | |
| 715 | * Support for CRIS has been removed from ports. |
| 716 | |
| 717 | * A new class of installed header has been documented for low-level |
| 718 | platform-specific functionality. PowerPC added the first instance with a |
| 719 | function to provide time base register access. Contributed by Tulio |
| 720 | Magno Quites Machado Filho. |
| 721 | |
| 722 | * ix86 configurations now install header files that are consistent with |
| 723 | what x86-64 configurations install. These same header files can be used |
| 724 | for -m32, -m64, or -mx32 builds. |
| 725 | Contributed by H.J. Lu. |
| 726 | |
| 727 | * Math library bug fixes. A thorough audit of all open math library bugs was |
| 728 | conducted by Joseph Myers. Significant progress was made on many math |
| 729 | library bugs resulting in more accurate exceptions and function results. |
| 730 | Many thanks to all those that contributed including Andreas Jaeger for his |
| 731 | patch review and work on the x87 trigonometric instruction issues. |
| 732 | |
| 733 | * Timezone data is no longer installed. Timezone-related binaries and scripts |
| 734 | will continue to be installed. Users should obtain their timezone data from |
| 735 | their distribution provider or from the tzdata package at |
| 736 | <ftp://munnari.oz.au/pub/>. |
| 737 | |
| 738 | Version 2.15 |
| 739 | |
| 740 | * The following bugs are resolved with this release: |
| 741 | |
| 742 | 6779, 6783, 9696, 10103, 10709, 11589, 11929, 12403, 12786, 12840, 12847, |
| 743 | 12868, 12852, 12874, 12885, 12892, 12906, 12907, 12922, 12935, 12962, |
| 744 | 13007, 13021, 13061, 13062, 13067, 13068, 13085, 13088, 13090, 13092, |
| 745 | 13096, 13114, 13118, 13123, 13134, 13138, 13147, 13150, 13166, 13179, |
| 746 | 13185, 13189, 13192, 13268, 13276, 13282, 13291, 13305, 13328, 13335, |
| 747 | 13337, 13344, 13358, 13367, 13413, 13416, 13423, 13439, 13446, 13472, |
| 748 | 13484, 13506, 13515, 13523, 13524, 13538, 13540 |
| 749 | |
| 750 | * New program pldd to list loaded object of a process |
| 751 | Implemented by Ulrich Drepper. |
| 752 | |
| 753 | * Add nss_db support back to glibc. No more dependency on Berkeley db |
| 754 | and support for initgroups lookups. |
| 755 | Implemented by Ulrich Drepper. |
| 756 | |
| 757 | * Optimized strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-32. |
| 758 | Contributed by HJ Lu. |
| 759 | |
| 760 | * Improved strcpy, strncpy, stpcpy, stpncpy for SSE2 and SSSE3 on x86-64. |
| 761 | Contributed by HJ Lu. |
| 762 | |
| 763 | * Optimized strcat, strncat on x86-64 and optimized wcscmp, wcslen, strnlen |
| 764 | on x86-32 and x86-64. |
| 765 | Contributed by Liubov Dmitrieva. |
| 766 | |
| 767 | * Optimized strchr and strrchr for SSE on x86-32. |
| 768 | Contributed by Liubov Dmitrieva. |
| 769 | |
| 770 | * Optimized memchr, memrchr, rawmemchr, memcmp, wmemcmp, wcschr, wcscpy |
| 771 | for x86-64 and x86-32. |
| 772 | Contributed by Liubov Dmitrieva. |
| 773 | |
| 774 | * New interfaces: scandirat, scandirat64 |
| 775 | Implemented by Ulrich Drepper. |
| 776 | |
| 777 | * Checking versions of FD_SET, FD_CLR, and FD_ISSET added. |
| 778 | Implemented by Ulrich Drepper. |
| 779 | |
| 780 | * nscd now also caches the netgroup database. |
| 781 | Implemented by Ulrich Drepper. |
| 782 | |
| 783 | * Integrate libm with gcc's -ffinite-math-only option. |
| 784 | Implemented by Ulrich Drepper. |
| 785 | |
| 786 | * Lots of generic, 64-bit, and x86-64-specific performance optimizations |
| 787 | to math functions. Implemented by Ulrich Drepper. |
| 788 | |
| 789 | * Optimized strcasecmp and strncasecmp for AVX on x86-64. |
| 790 | Implemented by Ulrich Drepper. |
| 791 | |
| 792 | * New Linux interfaces: process_vm_readv, process_vm_writev |
| 793 | |
| 794 | * Optimized strcasecmp and strncasecmp for SSSE3 and SSE4.2 on x86-32. |
| 795 | Implemented by Ulrich Drepper. |
| 796 | |
| 797 | * Optimized nearbyint and strcasecmp for PPC. |
| 798 | Implemented by Adhemerval Zanella. |
| 799 | |
| 800 | * New locales: bho_IN, unm_US, es_CU, ta_LK |
| 801 | |
| 802 | Version 2.14 |
| 803 | |
| 804 | * The following bugs are resolved with this release: |
| 805 | |
| 806 | 386, 6420, 7101, 9730, 9732, 9809, 10138, 10149, 10157, 11099, 11257, |
| 807 | 11258, 11487, 11532, 11558, 11578, 11634, 11653, 11668, 11697, 11724, |
| 808 | 11781, 11799, 11820, 11837, 11857, 11869, 11892, 11895, 11901, 11945, |
| 809 | 11947, 11952, 11987, 12052, 12083, 12158, 12178, 12200, 12346, 12350, |
| 810 | 12393, 12420, 12432, 12445, 12449, 12453, 12454, 12460, 12469, 12489, |
| 811 | 12509, 12510, 12511, 12518, 12527, 12541, 12545, 12551, 12582, 12583, |
| 812 | 12587, 12597, 12601, 12611, 12625, 12626, 12631, 12650, 12653, 12655, |
| 813 | 12660, 12671, 12681, 12684, 12685, 12711, 12713, 12714, 12717, 12723, |
| 814 | 12724, 12734, 12738, 12746, 12766, 12775, 12777, 12782, 12788, 12792, |
| 815 | 12795, 12811, 12813, 12814, 12841 |
| 816 | |
| 817 | * The RPC implementation in libc is obsoleted. Old programs keep working |
| 818 | but new programs cannot be linked with the routines in libc anymore. |
| 819 | Programs in need of RPC functionality must be linked against TI-RPC. |
| 820 | The TI-RPC implementation is IPv6 enabled and there are other benefits. |
| 821 | |
| 822 | Visible changes of this change include (obviously) the inability to link |
| 823 | programs using RPC functions without referencing the TI-RPC library and the |
| 824 | removal of the RPC headers from the glibc headers. |
| 825 | Implemented by Ulrich Drepper. |
| 826 | |
| 827 | * New Linux interfaces: clock_adjtime, name_to_handle_at, open_by_handle_at, |
| 828 | syncfs, setns, sendmmsg |
| 829 | |
| 830 | * New locales: os_RU, bem_ZA, en_ZA, ff_SN, sw_KE, sw_TZ, lb_LU, wae_CH, |
| 831 | yue_HK, lij_IT, mhr_RU |
| 832 | |
| 833 | * New encodings: CP770, CP771, CP772, CP773, CP774 |
| 834 | |
| 835 | * New program sotruss to trace calls through PLTs |
| 836 | Implemented by Ulrich Drepper. |
| 837 | |
| 838 | * The malloc hook implementation is marked deprecated and will be removed |
| 839 | from the default implementation in the next version. The design never |
| 840 | worked ever since the introduction of threads. Even programs which do |
| 841 | not create threads themselves can use multiple threads created internally. |
| 842 | |
| 843 | Version 2.13 |
| 844 | |
| 845 | * The following bugs are resolved with this release: |
| 846 | |
| 847 | 3268, 6812, 7066, 10085, 10484, 10563, 10851, 11149, 11155, 11577, 11611, |
| 848 | 11640, 11655, 11701, 11840, 11856, 11883, 11903, 11904, 11968, 11979, |
| 849 | 12005, 12037, 12067, 12077, 12078, 12092, 12093, 12107, 12108, 12113, |
| 850 | 12140, 12159, 12167, 12191, 12194, 12201, 12204, 12205, 12207, 12348, |
| 851 | 12378, 12394, 12397 |
| 852 | |
| 853 | * New Linux interfaces: prlimit, prlimit64, fanotify_init, fanotify_mark |
| 854 | |
| 855 | * POWER7 optimizations: memset, memcmp, strncmp |

| 885 | will not be used to fill in password fields in the passwd.byname replies. |
| 886 | Instead it is used to synthesize the shadow.byname table, should it be |
| 887 | missing. This is a useful mode in some installations involving Solaris. |
| 888 | Implemented by Ulrich Drepper. |
| 889 | |

| 904 | mkostemps64 |
| 905 | Implemented by Ulrich Drepper. |
| 906 | |
| 907 | * Checking version of longjmp added that fails if an uninitialized stack |
| 908 | frame would be created. Implemented by Ulrich Drepper. |
| 909 | |
| 910 | * STT_GNU_IFUNC is now supported in static executables. |
| 911 | Implemented by H.J. Lu. |

| 917 | strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2). |
| 918 | Contributed by H.J. Lu. |
| 919 | |
| 920 | strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3). |
| 921 | Implemented by Ulrich Drepper. |
| 922 | |
| 923 | * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk, |

| 934 | Implemented by Ulrich Drepper. |
| 935 | |
| 936 | * Implement second fallback mode for optimized DNS lookup for even more |
| 937 | broken environments. If two requests from the same port are not |
| 938 | handled correctly close the socket and open a new one before sending |
| 939 | the second request. The 'single-request-reopen' option in /etc/resolv.conf |
| 940 | can be used to select this mode right away, instead of rediscovering the |
| 941 | necessity is every process again. |
| 942 | Implemented by Ulrich Drepper. |
| 943 | |
| 944 | * New resolver flag RES_USE_DNSSEC to enable use of verified lookup. |
| 945 | Implemented by Adam Tkac. |

| 970 | Implemented by Ulrich Drepper. |
| 971 | |
| 972 | * Correct declarations of string function when used in C++ code. This |
| 973 | could lead to compile errors for invalid C++ code. |
| 974 | |
| 975 | * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are |
| 976 | now in POSIX. |
| 977 | |
| 978 | * New POSIX 2008 interface: psiginfo |
| 979 | Implemented by Ulrich Drepper. |
| 980 | |
| 981 | * New ISO C++1x interfaces: quick_exit, at_quick_exit |
| 982 | Implemented by Ulrich Drepper. |
| 983 | |
| 984 | * Support for selecting between multiple function definitions at runtime |
| 985 | using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper. |
| 986 | |
| 987 | * The libcrypt library can now use the hash function implementations in |
| 988 | NSS. Implemented by Ulrich Drepper. |
| 989 | |
| 990 | * The malloc implementation can be compiled to be less memory efficient |
| 991 | but higher performing in multi-threaded programs. |
| 992 | Implemented by Ulrich Drepper. |
| 993 | |
| 994 | * New locales: nan_TW@latin, ks_IN |
| 995 | |

| 1000 | and extend existing format specifiers. |
| 1001 | Implemented by Ulrich Drepper. |
| 1002 | |
| 1003 | * Handling for group shadow files has been added. |
| 1004 | Implemented by Ulrich Drepper. |
| 1005 | |
| 1006 | * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS |
| 1007 | servers (the case, e.g., for some people using the built-in DNS |
| 1008 | server in ADSL modems/routers). There is a once-per-process timeout |
| 1009 | in case of a broken server. To avoid it, users can run nscd or put |
| 1010 | 'options single-request' in /etc/resolv.conf. |
| 1011 | Implemented by Ulrich Drepper. |
| 1012 | |
| 1013 | Version 2.9 |

| 1038 | |
| 1039 | * New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2 |
| 1040 | |
| 1041 | * Implement "e" option for popen to open file descriptor with the |
| 1042 | close-on-exec flag set. Implemented by Ulrich Drepper. |
| 1043 | |
| 1044 | * Implement "b" mode for fmemopen. In this mode writes writes don't |
| 1045 | implicitly add a NUL byte and seeks from the end of the buffer really |
| 1046 | use the buffer end, not the string length as the basis. |
| 1047 | Implemented by Ulrich Drepper. |
| 1048 | |
| 1049 | * Many functions, exported and internal, now atomically set the close-on-exec |
| 1050 | flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper. |

| 1166 | * nscd can now cache the services database. Implemented by Ulrich Drepper. |
| 1167 | |
| 1168 | Version 2.5 |
| 1169 | |
| 1170 | * The following bugs are resolved with this release: |
| 1171 | |
| 1172 | 39, 68, 192, 352, 388, 531, 935, 1006, 1201, 1203, 1386, 1782, 1783, 1784, |
| 1173 | 1785, 1786, 1787, 1951, 1974, 1996, 2072, 2098, 2125, 2134, 2158, 2182, |
| 1174 | 2349, 2376, 2386, 2389, 2415, 2418, 2420, 2423, 2450, 2451, 2466, 2472, |
| 1175 | 2473, 2477, 2498, 2499, 2501, 2502, 2505, 2507, 2508, 2509, 2517, 2526, |
| 1176 | 2569, 2571, 2592, 2611, 2625, 2632, 2644, 2662, 2680, 2683, 2684, 2693, |
| 1177 | 2695, 2703, 2734, 2751, 2764, 2766, 2775, 2792, 2821, 2823, 2832, 2841, |
| 1178 | 2843, 2883, 2892, 2908, 2914, 2926, 2961, 2978, 2980, 2987, 2997, 2998, |
| 1179 | 3013, 3018, 3034, 3040, 3044, 3123, 3124, 3137, 3138, 3143, 3155, 3189, |
| 1180 | 3225, 3251, 3252, 3253, 3273 |
| 1181 | |
| 1182 | * For Linux, the sorting of addresses returned by getaddrinfo now also |
| 1183 | handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled. |
| 1184 | Implemented by Ulrich Drepper. |
| 1185 | |
| 1186 | * Allow system admin to configure getaddrinfo with the /etc/gai.conf file. |
| 1187 | Implemented by Ulrich Drepper. |
| 1188 | |
| 1189 | * New Linux interfaces: splice, tee, sync_file_range, vmsplice. |
| 1190 | |
| 1191 | * New iconv module for MIK. Contributed by Alexander Shopov. |
| 1192 | |
| 1193 | * For sites with broken group and/or passwd database, the auto-propagate |
| 1194 | option of nscd can prevent creating ID lookup entries from the results |
| 1195 | of a name lookup and vice versa. This usually is no problem but some |
| 1196 | site might have problems with the default behavior. |
| 1197 | Implemented by Ulrich Drepper. |
| 1198 | |
| 1199 | * Iterating over entire database in NIS can be slow. With the |
| 1200 | SETENT_BATCH_READ option in /etc/default/nss a system admin can decide |
| 1201 | to trade time for memory. The entire database will be read at once. |
| 1202 | Implemented by Ulrich Drepper. |
| 1203 | |
| 1204 | * The interfaces introduced in RFC 3542 have been implemented by |
| 1205 | Ulrich Drepper. |
| 1206 | |
| 1207 | * Support for the new ELF hash table format was added by Ulrich Drepper. |
| 1208 | |
| 1209 | * Support for priority inheritance mutexes added by Jakub Jelinek and |
| 1210 | Ulrich Drepper. |
| 1211 | |
| 1212 | * Support for priority protected mutexes added by Jakub Jelinek. |
| 1213 | |
| 1214 | * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN, |
| 1215 | or_IN, csb_PL, fy_NL, sr_ME. |
| 1216 | |
| 1217 | Version 2.4 |
| 1218 | |
| 1219 | * More overflow detection functions. |
| 1220 | |
| 1221 | * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153, |
| 1222 | IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba. |
| 1223 | |
| 1224 | More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097, |
| 1225 | IBM1112, IBM1123, IBM1130, IBM1140, IBM1141, IBM1142, IBM1143, IBM1144, |
| 1226 | IBM1145, IBM1146, IBM1147, IBM1148, IBM1149, IBM1166, IBM1167, IBM4517, |
| 1227 | IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712, |
| 1228 | IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed |
| 1229 | by Masahide Washizawa. |
| 1230 | |
| 1231 | * It is now possible to install audit libraries for the dynamic linker using |
| 1232 | LD_AUDIT. Implemented by Ulrich Drepper. |
| 1233 | |
| 1234 | * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no |
| 1235 | longer supported. The new NPTL implementation requires Linux 2.6 kernels. |
| 1236 | For a libc and libpthread that works well on Linux 2.4 kernels, we |
| 1237 | recommend using the stable 2.3 branch. |
| 1238 | |
| 1239 | * The new function open_wmemstream acts like open_memstream, |
| 1240 | but uses a wchar_t wide character buffer. |
| 1241 | |
| 1242 | * The new function ppoll is an improved version of poll, similar to pselect. |
| 1243 | |
| 1244 | * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat, |
| 1245 | futimesat, faccessat, mkdirat, mkfifoat, mknodat, |
| 1246 | renameat, unlinkat, linkat, symlinkat, readlinkat. |
| 1247 | |
| 1248 | * New Linux kernel system calls: unshare, |
| 1249 | inotify_init, inotify_add_watch, inotify_rm_watch. |
| 1250 | |
| 1251 | * The euidaccess function is now also known by the alias eaccess, |
| 1252 | for compatibility with some other systems. |
| 1253 | |
| 1254 | * Timezone data updated to 2006b version. |
| 1255 | |
| 1256 | Version 2.3.6 |
| 1257 | |
| 1258 | * The following bugs are resolved with this release: |
| 1259 | |
| 1260 | 38, 253, 549, 622, 653, 721, 758, 851, 877, 915, 934, 955, 961, |
| 1261 | 1016, 1037, 1076, 1079, 1080, 1081, 1082, 1083, 1084, 1085, 1086, |
| 1262 | 1087, 1088, 1090, 1091, 1092, 1093, 1094, 1095, 1096, 1097, 1098, |
| 1263 | 1099, 1100, 1101, 1102, 1103, 1104, 1105, 1106, 1107, 1108, 1109, |
| 1264 | 1110, 1111, 1112, 1113, 1125, 1137, 1138, 1249, 1250, 1251, 1252, |
| 1265 | 1253, 1254, 1350, 1358, 1394, 1438, 1498, 1534 |
| 1266 | |

| 1268 | |
| 1269 | * As of this release, GCC 4 can be used to compile the C Library. |
| 1270 | |
| 1271 | * Timezone data updated to 2005m version. |
| 1272 | |
| 1273 | Version 2.3.5 |
| 1274 | |
| 1275 | * The following bugs are resolved with this release: |
| 1276 | |
| 1277 | 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719, |
| 1278 | 722, 723, 725, 726, 727, 728, 729, 730, 731, 732, 733, 734, 735, 736, |
| 1279 | 737, 738, 739, 740, 741, 742, 743, 744, 745, 765, 767, 768, 769, 776, |
| 1280 | 777, 787, 821, 822, 823, 825 |

| 1283 | |
| 1284 | Version 2.3.4 |
| 1285 | |
| 1286 | * Support for RFC 3678. Real implementations exist only for Linux so far. |
| 1287 | Implemented by Ulrich Drepper. |
| 1288 | |
| 1289 | * nscd can now cache entries persistently. Expiring entries are reloaded. |
| 1290 | For speedups the cache can be shared in memory with client processes. |
| 1291 | Implemented by Ulrich Drepper. |
| 1292 | |
| 1293 | * nscd can now perform SELinux checks. |
| 1294 | Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>. |
| 1295 | |
| 1296 | * getaddrinfo queries are now cached. Canonical name lookup is performed |
| 1297 | efficiently. |
| 1298 | Implemented by Ulrich Drepper. |
| 1299 | |
| 1300 | * The nothrow function attribute is used when headers are used by gcc when |
| 1301 | compiling C code. This can avoid significant amounts of exception |
| 1302 | handling data. |
| 1303 | |
| 1304 | * The malloc functions perform more error checking and are stricter when |
| 1305 | it comes to reacting on errors. The default action is to terminate |
| 1306 | the process after showing an error message. Implemented by Ulrich Drepper. |
| 1307 | |
| 1308 | * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int |
| 1309 | lookups anymore unless explicitly requested. Implemented by Ulrich Drepper. |
| 1310 | |
| 1311 | * Namespaces in ld.so are implemented. DSOs can be loaded in separate |
| 1312 | namespaces using the new function dlmopen(). This feature is of course, |
| 1313 | like most other dynamic loading functionality, not available in statically |
| 1314 | linked applications. Implemented by Ulrich Drepper. |
| 1315 | |
| 1316 | * Low-overhead boundary checking variants of string and some stdio functions |
| 1317 | were added. These are to be used in conjunction with a gcc patch by |
| 1318 | Jakub Jelinek which adds calls to these functions if possible. |
| 1319 | Implemented by Jakub Jelinek and Ulrich Drepper. |
| 1320 | |
| 1321 | * Old code for several operating systems and machine architectures that |
| 1322 | have not been in working condition in a long time have been removed from |
| 1323 | the main source tree maintained by the GNU C Library's maintainers. |
| 1324 | These files are now reside in the separate `ports' source module |
| 1325 | that is usable as an add-on when building the library. |
| 1326 | |
| 1327 | Version 2.3.3 |
| 1328 | |
| 1329 | * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to |
| 1330 | interrogate the dynamic linker, compatible with the Solaris interface. |
| 1331 | |
| 1332 | * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64; |
| 1333 | implemented by Paul Mackerras, Steven Munroe, and Roland McGrath. |
| 1334 | |
| 1335 | * getifaddrs now uses the netlink interface on Linux to get its information. |
| 1336 | Implemented by Thorsten Kukuk. |
| 1337 | |
| 1338 | * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF. |
| 1339 | Implemented by Ulrich Drepper. |
| 1340 | |
| 1341 | * support for non-executable stacks on x86 has been added. Changes mostly |
| 1342 | by Roland McGrath. |
| 1343 | |
| 1344 | * regex is now much faster for multibyte locales. Changes by Jakub Jelinek |
| 1345 | and Ulrich Drepper. |
| 1346 | |
| 1347 | * getaddrinfo now performs destination address selection according to |
| 1348 | RFC 3484. |
| 1349 | |
| 1350 | Version 2.3.2 |
| 1351 | |
| 1352 | * Thread-safe interfaces for many functions that access locale data |
| 1353 | were added in version 2.3, but these features were omitted from NEWS. |
| 1354 | Many functions have variants with an `_l' suffix that take a `locale_t' |
| 1355 | object as a parameter rather than consulting the current locale. |
| 1356 | The new functions `newlocale', `duplocale', and `freelocale' in <locale.h> |
| 1357 | create and maintain `locale_t' objects. Additionally, the new function |
| 1358 | `uselocale' sets "the current locale" (as used by functions not so |
| 1359 | parameterized) set for an individual thread. These features were added |
| 1360 | in version 2.3, implemented by Ulrich Drepper and Roland McGrath. |
| 1361 | |
| 1362 | * The functions getresuid, getresgid, setresuid, and setresgid, which |
| 1363 | have long been available on Linux, are now declared in <unistd.h> |
| 1364 | and are now also available on the Hurd. |
| 1365 | |
| 1366 | * ELF thread-local storage support (TLS) now works on x86-64. |
| 1367 | |
| 1368 | * The new dynamic string token $LIB is expanded in shared library names. |
| 1369 | This normally expands to lib, but on some 64-bit platforms to lib64 instead. |
| 1370 | |
| 1371 | * Aldy Hernandez contributed complete software floating point support for |
| 1372 | PowerPC machines with no FPU. |
| 1373 | |
| 1374 | * fexecve is implemented on Linux. |
| 1375 | |
| 1376 | * The `btowc' function should work at least twice as fast due to |
| 1377 | specialized callbacks in the iconv modules. Implemented by Bruno Haible. |
| 1378 | |
| 1379 | * With approriate thread add-ons cancelable functions are now implemented |
| 1380 | in libc.so as well. No need to call the function in libpthread. This |
| 1381 | change allowed to finally disable the incorrect and expensive handling |
| 1382 | of weak definition in ld.so. |
| 1383 | |
| 1384 | * Yet more PLT entries in libc.so have been removed. We finally arrived |
| 1385 | at the bare minimum. Startup times improved appropriately. |
| 1386 | |
| 1387 | * Support for the new Linux/x86 system call interface was added. The |
| 1388 | AT_SYSINFO auxiliary vector entry is recognized and handled. |
| 1389 | |
| 1390 | Version 2.3 |
| 1391 | |
| 1392 | * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164 |
| 1393 | charsets. |
| 1394 | |
| 1395 | * iconv (the program and the interface) now accepts empty names (excluding |
| 1396 | options like //TRANSLIT) to mean "use charset of current locale". |
| 1397 | |
| 1398 | * localedef can now transliterate characters in strings which are not in |
| 1399 | the provided charmap. The information from the input locale is used. |
| 1400 | |
| 1401 | * Prelinking support was added for ELF targets. This requires additional |
| 1402 | tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek. |
| 1403 | |
| 1404 | * Read-only stdio streams now use mmap to speed up operation by eliminating |
| 1405 | copying and buffer underflows. To use add 'm' to the mode string of |
| 1406 | the fopen/fdopen/freopen call. Implemented by Ulrich Drepper. |
| 1407 | |
| 1408 | * The malloc functions were completely rewritten by Wolfram Gloger based |
| 1409 | on Doug Lea's malloc-2.7.0.c. |
| 1410 | |
| 1411 | * Isamu Hasegawa contributed a completely new and POSIX-conformant |
| 1412 | implementation of regex. |
| 1413 | |
| 1414 | * Bruno Haible upgraded the iconv and locale implementation to support |
| 1415 | Unicode 3.2. |
| 1416 | |
| 1417 | * Contents of the LC_* and LANG environment variables in the CEN style are |
| 1418 | not recognized anymore. It never was used. Change by Ulrich Drepper. |
| 1419 | |
| 1420 | * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF |
| 1421 | thread-local storage (TLS) ABI on some platforms. |
| 1422 | Changes by Ulrich Drepper. SH support by Kaz Kojima. |
| 1423 | |
| 1424 | * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213, |
| 1425 | EUC-JISX0213, and TSCII. |
| 1426 | |
| 1427 | * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs': |
| 1428 | BSD-compatible interface for getting all network interface addresses. |
| 1429 | Implementation for IPv4 by Roland McGrath. |
| 1430 | |
| 1431 | * Loading of locale data is faster due to the introduction of a locale |
| 1432 | archive. Implemented by Roland McGrath and Ulrich Drepper. |
| 1433 | |
| 1434 | * Startup times are significantly reduced by not using exported functions |
| 1435 | inside the library itself. Changes by Jakub Jelinek, Roland McGrath, |
| 1436 | and Ulrich Drepper. |
| 1437 | |
| 1438 | * Steven Munroe contributed a port to PowerPC64/Linux. |
| 1439 | |
| 1440 | Version 2.2.6 |
| 1441 | |
| 1442 | * The Hurd now uses the GNU libio implementation of stdio rather than the |
| 1443 | old GNU stdio implementation, and uses a new ABI (libc.so.0.3). |
| 1444 | |
| 1445 | * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file |
| 1446 | with the same behavior as the Linux system call of the same name. |
| 1447 | |
| 1448 | Version 2.2.5 |
| 1449 | |
| 1450 | * Stephen Moshier implemented log2, log10, powl and cbrtl for the |
| 1451 | 128-bit long double format. |
| 1452 | |
| 1453 | * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160, |
| 1454 | IBM1161, and IBM1162 charsets. |
| 1455 | |
| 1456 | * Andreas Jaeger contributed a port to x86-64/Linux. |
| 1457 | |
| 1458 | * Peter Bruin contributed a port to PowerPC/Hurd. |
| 1459 | |
| 1460 | * libc functions using I/O streams now can handle wide-oriented streams |
| 1461 | as well. |
| 1462 | |
| 1463 | * optimizations in the dynamic linker. Binaries created by recent binutils |
| 1464 | versions start up quicker due to reduced time spent on relocations. |
| 1465 | |
| 1466 | * Support for use of gcc3 added by Jakub Jelinek and HJ Lu. |
| 1467 | |
| 1468 | Version 2.2.4 |
| 1469 | |
| 1470 | * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh, |
| 1471 | asinh, atanh, j0 for the 128-bit long double format. |
| 1472 | |
| 1473 | * Bruno Haible updated all the code handling Unicode in some form to |
| 1474 | support Unicode 3.1. |
| 1475 | |
| 1476 | * Speed of regex for single-byte locales is back to previous levels. |
| 1477 | Patch by Isamu Hasegawa. |
| 1478 | |
| 1479 | * Alpha, SPARC, and IA-64 now also using floating stacks. |
| 1480 | |
| 1481 | * Startup time of internationalized applications greatly improved through |
| 1482 | iconv cache. Use iconvconfig to generate the cache file. |
| 1483 | Contributed by Ulrich Drepper. |
| 1484 | |
| 1485 | * The IA-64 specific part of ld.so was rewritten to eliminate some pretty |
| 1486 | severe performance problems. Patch by David Mosberger. |
| 1487 | |
| 1488 | * The Hurd port got a lot more functionality like AIO, various stdio |
| 1489 | extensions, etc. Mainly done by Roland McGrath. |
| 1490 | |
| 1491 | * mtrace can now lookup symbols in shared libraries. |
| 1492 | |
| 1493 | Version 2.2.3 |
| 1494 | |
| 1495 | * Intel's IA-64 math library is largely integrated. It provides fast and |
| 1496 | accurate implementatations for most basic and standard math functions |
| 1497 | in float, double, and long double format. |
| 1498 | |
| 1499 | * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc, |
| 1500 | and asin for the 96-bit long double format and asin, log, tan for the |
| 1501 | 128-bit long double format. |
| 1502 | |
| 1503 | * The beginning of a last-bit accurate math library by IBM Haifa were added. |
| 1504 | The basic double functions exist today. Contributed by Abraham Ziv |
| 1505 | <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis |
| 1506 | <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>. |
| 1507 | |
| 1508 | * An asynchronous name lookup library was added. The interface is designed |
| 1509 | after POSIX AIO. The proposal was circulated beforehand to get comments. |
| 1510 | No negative ones came in. Implemented by Ulrich Drepper. |
| 1511 | |
| 1512 | * Port to S390/64bit contributed by Martin Schwidefsky |
| 1513 | <schwidefsky@de.ibm.com>. |
| 1514 | |
| 1515 | * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family |
| 1516 | of functions for Linux/IA-64. |
| 1517 | |
| 1518 | * The RPC code is now thread safe. Threads can now use the same service |
| 1519 | of different services at the same time. Patch by Eric Norum |
| 1520 | <eric.norum@usask.ca> with some help by Ulrich Drepper. |
| 1521 | |
| 1522 | * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext |
| 1523 | family of functions for Linux/S390. |
| 1524 | |
| 1525 | * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family |
| 1526 | of functions for Linux/x86. |
| 1527 | |
| 1528 | * Port to Linux/CRIS contributed by Axis Communications. |
| 1529 | |
| 1530 | Version 2.2.2 |
| 1531 | |
| 1532 | * Lots of headers were cleaned up. Using the tool in the conform/ subdir |
| 1533 | we can now check for namespace violations and missing declarations. The |
| 1534 | result is that almost all headers are now Unix-compliant (as defined in |
| 1535 | the upcoming XPG6). The negative side is that some programs might need |
| 1536 | corrections, too, if they depend on the incorrect form of the headers in |
| 1537 | previous versions which defined too many symbols and included too many |
| 1538 | other headers. |
| 1539 | |
| 1540 | * regex now handles multibyte character sets correctly. |
| 1541 | Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>. |
| 1542 | |
| 1543 | * iconv (the program) does now conform to the upcoming XPG6 and handles |
| 1544 | charmaps. Instead of the charset names the path of charmaps can be |
| 1545 | provided and the conversion happens based on this data. |
| 1546 | Contributed by Ulrich Drepper. |
| 1547 | |
| 1548 | * The locale program now provides detailed information about the installed |
| 1549 | locales. While |
| 1550 | |
| 1551 | locale -a |
| 1552 | |
| 1553 | only lists the names of the supported locales |
| 1554 | |
| 1555 | locale -a --verbose |
| 1556 | |
| 1557 | provides details such as country, language, and codeset name. |
| 1558 | Contributed by Ulrich Drepper. |
| 1559 | |
| 1560 | Version 2.2.1 |
| 1561 | |
| 1562 | * The gencat program now parses the input file according to the charset |
| 1563 | selected by the LC_CTYPE category. This is important for stateful |
| 1564 | character sets. To make generating catalogs easier there is a way |
| 1565 | to overwrite the charset selected by the locale: before the first |
| 1566 | message or $ quote line the catalog can contain a line like |
| 1567 | |
| 1568 | $ codeset=ISO-8859-2 |
| 1569 | |
| 1570 | to select the charset (ISO-8859-2 in this case). |
| 1571 | |
| 1572 | Implemented by Shinya Hanataka and Ulrich Drepper. |
| 1573 | |
| 1574 | * New codeset conversion modules: IBM-922 (Estonia PC codeset), |
| 1575 | IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset). |
| 1576 | Contributed by Masahide Washizawa <washi@jp.ibm.com>. |
| 1577 | |
| 1578 | * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson |
| 1579 | <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>. |
| 1580 | |
| 1581 | * The LANGUAGE environment variable is now ignored unless the locale is |
| 1582 | changed from the default "C" locale. |
| 1583 | |
| 1584 | * The usual bug fixes. |
| 1585 | |
| 1586 | Version 2.2 |
| 1587 | |
| 1588 | * Greg McGary added runtime support for bounds checking using gcc's |
| 1589 | new -fbounded-pointers option. ix86 target is complete. PowerPC |
| 1590 | is in progress. |
| 1591 | |
| 1592 | * Thorsten Kukuk added secure mode support to nscd. |
| 1593 | |
| 1594 | * The Berkeley db libraries have been removed. |
| 1595 | |
| 1596 | Related, the nss_db module is now in a separate package since it |
| 1597 | obviously requires a database library being available. |
| 1598 | |
| 1599 | * Wide character I/O streams implemented by Ulrich Drepper. |
| 1600 | |
| 1601 | * Functions from the extended socket API added by Ulrich Drepper. |
| 1602 | |
| 1603 | * Functions feenableexcept and fedisableexcept to control the |
| 1604 | behaviour of individual exceptions have been added by Andreas Jaeger. |
| 1605 | |
| 1606 | * ldconfig program added by Andreas Jaeger and Jakub Jelinek. |
| 1607 | |
| 1608 | * The resolver code has been updated from bind 8.2.3-T5B which supports |
| 1609 | threads. The integration was done by Andreas Jaeger, Adam D. Bradley, |
| 1610 | and Mark Kettenis. |
| 1611 | |
| 1612 | This change could in some situations effect backward compatibility. Since |
| 1613 | now `_res' is a thread-local instead of a global variable, modifying it |
| 1614 | in one thread does not have any effect in other threads. |
| 1615 | |
| 1616 | The resolver library was also extended to allow IPv6 as the transport |
| 1617 | protocol for the requests. This work was done by Stig Venaas. |
| 1618 | |
| 1619 | * Compatibility code for K&R C compilers has been removed from the |
| 1620 | header files. A ISO C compiler is needed to use the library |
| 1621 | (conforming to either C89 or C99 standard). |
| 1622 | |
| 1623 | * Complete rewrite of the localedef program to support multibyte character |
| 1624 | sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll, |
| 1625 | strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work. |
| 1626 | Implemented by Ulrich Drepper. |
| 1627 | |
| 1628 | Bruno Haible significantly improved the generation and use of the data |
| 1629 | structures for the wide character tables. |
| 1630 | |
| 1631 | * Plural handling in gettext implemented by Ulrich Drepper. |
| 1632 | |
| 1633 | * The utmp daemon has been removed. |
| 1634 | |
| 1635 | * The port to MIPS-Linux has been finished by Andreas Jaeger. |
| 1636 | |
| 1637 | * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima |
| 1638 | and Yutaka Niibe. |
| 1639 | |
| 1640 | * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper. |
| 1641 | |
| 1642 | * POSIX barriers implemented by Kaz Kylheku. |
| 1643 | |
| 1644 | * POSIX spawn function family implemented by Ulrich Drepper. |
| 1645 | |
| 1646 | * POSIX spinlocks are now available. |
| 1647 | |
| 1648 | * Timed wait functions for mutex, rwlock, and semaphores are implemented. |
| 1649 | |
| 1650 | * the configure option --enable-kernel=X.Y.Z allows to strip out |
| 1651 | compatibility for kernel versions before X.Y.Z. This is currently only |
| 1652 | implemented for Linux. |
| 1653 | |
| 1654 | * the sockaddr_in6 structure changed. The IPv6 working group added a new |
| 1655 | field sin6_scope_id. This means that all programs using IPv6 should be |
| 1656 | recompiled. Don't expect binary compatibility with previous glibc |
| 1657 | versions. |
| 1658 | |
| 1659 | * various conversion modules for IBM character sets contributed by |
| 1660 | Masahide Washizawa. |
| 1661 | |
| 1662 | * IA-64 port by Jes Sorensen and HJ Lu. |
| 1663 | |
| 1664 | Version 2.1.3 |
| 1665 | |
| 1666 | * bug fixes |
| 1667 | |
| 1668 | |
| 1669 | Version 2.1.2 |
| 1670 | |
| 1671 | * bug fixes |
| 1672 | |
| 1673 | |
| 1674 | Version 2.1.1 |
| 1675 | |
| 1676 | * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added. |
| 1677 | |
| 1678 | * New xdr functions are added; some rpc functions are now 64bit clean. |
| 1679 | |
| 1680 | * Fixed a number of bugs and memory leaks (especially in NIS+ code). |
| 1681 | |
| 1682 | * Fixed known incompatibilities with glibc 2.0. |
| 1683 | |
| 1684 | * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx. |
| 1685 | |
| 1686 | * Optimized a number of functions (especially the ELF dynamic loader). |
| 1687 | |
| 1688 | * Update timezone data files. |
| 1689 | |
| 1690 | * lots of charmaps corrections |
| 1691 | |
| 1692 | * some new locale definitions and charmaps |
| 1693 | |
| 1694 | |
| 1695 | Version 2.1 |
| 1696 | |
| 1697 | * Richard Henderson corrected size of struct timeval on Linux/Alpha to |
| 1698 | conform to POSIX member type requirements. Symbol versions have been |
| 1699 | adjusted as needed within the library, and for direct use by applications, |
| 1700 | but there is potential for problems if third-party libraries use |
| 1701 | struct timeval as part of their interface. This does not present |
| 1702 | a problem for X and other "essential" system libraries. |
| 1703 | |
| 1704 | * An additional locale model to support C++ Standard Library locale |
| 1705 | model and probably more was implemented by Ulrich Drepper. |
| 1706 | |
| 1707 | * Eric Youngdale and Ulrich Drepper implemented versioning of objects on |
| 1708 | symbol level. |
| 1709 | |
| 1710 | * Miles Bader provided the `argp' function family to support hierachical |
| 1711 | command line argument parsing, layered on top of getopt. |
| 1712 | |
| 1713 | * strtod accepts new hexadecimal floating-point format from ISO C 9X. |
| 1714 | |
| 1715 | * printf has two new specifiers %a and %A to print hexadecimal flaoting-point |
| 1716 | numbers. |
| 1717 | |
| 1718 | * scanf recognizes the %a and %A format for scanning floating point numbers. |
| 1719 | |
| 1720 | * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides |
| 1721 | information and interfaces for the available integer types. |
| 1722 | |
| 1723 | * about 130 new math functions were added to implement the ISO C9x math |
| 1724 | library. |
| 1725 | |
| 1726 | * the new header <complex.h> contains definitions of the complex math |
| 1727 | functions from ISO C 9X. |
| 1728 | |
| 1729 | * the new header <tgmath.h> defines generic macros to use complex or |
| 1730 | real valued functions. |
| 1731 | |
| 1732 | * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2. |
| 1733 | |
| 1734 | * Andreas Jaeger provided a test suite for the math library. |
| 1735 | |
| 1736 | * Mark Kettenis implemented the utmpx interface and an utmp daemon. |
| 1737 | |
| 1738 | * Ulrich Drepper added character set conversion functions (iconv). |
| 1739 | |
| 1740 | * Optimized string functions have been added. |
| 1741 | |
| 1742 | * The localedata addon is now part of glibc. |
| 1743 | |
| 1744 | * An implementation of profiling shared libraries was added by Ulrich Drepper. |
| 1745 | |
| 1746 | * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching |
| 1747 | daemon for NSS (nscd). |
| 1748 | |
| 1749 | Missing a better place here are some numbers on improvements. Under |
| 1750 | Linux 2.1.125 un-tar-ing the kernel sources takes |
| 1751 | |
| 1752 | user system wall |
| 1753 | |
| 1754 | using local files 12.19s 6.88s 22.91s |
| 1755 | |
| 1756 | using NIS 13.92s 8.91s 26.34s |
| 1757 | |
| 1758 | using NIS & nscd 10.37s 7.34s 25.30s |
| 1759 | |
| 1760 | using NIS+ 27.57s 30.37s 640.46s |
| 1761 | |
| 1762 | using NIS+ & nscd 10.25s 7.83s 26.51s |
| 1763 | |
| 1764 | using NIS & old nscd [1] 13.83s 8.32s 29.60s |
| 1765 | |
| 1766 | Keep in mind that non-namelookup related operations dominate above times. |
| 1767 | It was just a common complain that using NIS+ unpacking the kernel is |
| 1768 | horribly slow. |
| 1769 | |
| 1770 | [1] The old nscd implementation is not available anymore since it was |
| 1771 | distributed with glibc up to version 2.0.98 and thus is now replaced. |
| 1772 | |
| 1773 | * Tim Waugh provided an implementation of the POSIX.2 wordexp function family. |
| 1774 | |
| 1775 | * Mark Kettenis provided a Hesiod NSS module. |
| 1776 | |
| 1777 | * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN |
| 1778 | and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper). |
| 1779 | |
| 1780 | * rcmd can now handle netgroups (Dick Streefland). |
| 1781 | |
| 1782 | * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott |
| 1783 | Bambrough. |
| 1784 | |
| 1785 | * Support for the IPv6 protocol has been added to the socket API, as per the |
| 1786 | latest draft standards. |
| 1787 | |
| 1788 | * Support for Linux 2.2 has been added. |
| 1789 | |
| 1790 | * Interface changes relative to the latest 2.0.x release: |

| 2154 | |
| 2155 | * fix complex problems in Berkeley DB code |
| 2156 | |
| 2157 | * fix math functions |
| 2158 | |
| 2159 | Version 2.0.1 |
| 2160 | |
| 2161 | * fixed lots of header problems (especially Linux/GNU specific) |
| 2162 | |
| 2163 | * dynamic loader preserves all registers |
| 2164 | |
| 2165 | * Roland McGrath provided support for handling of auxiliary objects in |
| 2166 | the ELF dynamic loader. |
| 2167 | |
| 2168 | * support for parallel builds is improved |
| 2169 | |
| 2170 | Version 2.0 |
| 2171 | |
| 2172 | * GNU extensions are no longer declared by default. To enable them you |
| 2173 | must define the macro `_GNU_SOURCE' in your program or compile with |
| 2174 | `-D_GNU_SOURCE'. |
| 2175 | |
| 2176 | * The library has changed from using GNU ld symbol aliases to using weak |
| 2177 | symbols where available. The ELF object file format supports weak |
| 2178 | symbols; GNU ld also supports weak symbols in the a.out format. (There |
| 2179 | is also now support for other GNU ld extensions in ELF. Use the |
| 2180 | `--with-elf' option to configure to indicate you have ELF, and |
| 2181 | `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion |
| 2182 | of many files which contained only symbol aliases, reducing the size of |
| 2183 | the source and the compiled library; many other files were renamed to |
| 2184 | less cryptic names previously occupied by the symbol alias files. |
| 2185 | There is a new header file <elf.h> for programs which operate on |
| 2186 | files in the ELF format. |
| 2187 | |
| 2188 | * Converted to Autoconf version 2, so `configure' has more options. |
| 2189 | Run `configure --help' to see the details. |
| 2190 | |
| 2191 | * The library can now be configured to build profiling, highly-optimized |
| 2192 | (but undebuggable), and/or shared libraries (ELF with GNU ld only). The |
| 2193 | `--enable-profile', `--enable-omitfp', and `--enable-shared' options to |
| 2194 | `configure' enable building these extra libraries. The shared library is |
| 2195 | built by default when using both ELF and GNU ld. When shared libraries |
| 2196 | are enabled, the new library `-ldl' is available for arbitrary run-time |
| 2197 | loading of shared objects; its interface is defined in <dlfcn.h>. The |
| 2198 | new header file <link.h> gives access to the internals of the run-time |
| 2199 | dynamic linker, `ld.so'. The shell script `ldd' is similar to the |
| 2200 | application of same name on other systems and it provides information |
| 2201 | about dynamically linked binaries. |
| 2202 | |
| 2203 | * The C library now provides the run-time support code for profiling |
| 2204 | executables compiled with `-pg'. Programs can control the profiling code |
| 2205 | through the interface in <sys/gmon.h>. The `gmon.out' files written by |
| 2206 | the GNU C library can be read only by GNU `gprof' (from GNU binutils); |
| 2207 | the support for this file format was contributed by David Mosberger-Tang. |
| 2208 | |
| 2209 | * The math code has been replaced with a math library based on fdlibm from |
| 2210 | Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by |
| 2211 | Ian Taylor with `float' functions and by Ulrich Drepper with `long double' |
| 2212 | functions. The math functions now reside in a separate library, so |
| 2213 | programs using them will need to use `-lm' their linking commands. |
| 2214 | |
| 2215 | * John C. Bowman contributed optimized ix87 assembler inline functions. |
| 2216 | |
| 2217 | * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf' |
| 2218 | mechanism similar to that found in Solaris 2. This is now used for the |
| 2219 | group, passwd, hosts, networks, services, protocols, rpc, ethers, |
| 2220 | shadow, netgroup, publickey, and alias databases. The `nsswitch.conf' |
| 2221 | file controls what services are used for each individual database. This |
| 2222 | works by loading shared libraries with names specified in `nsswitch.conf', |
| 2223 | so service modules can be changed or added at any time without even |
| 2224 | relinking any program. Currently there are the file, db, and NIS based |
| 2225 | NSS services available. |
| 2226 | |
| 2227 | * The new functions `strtoq' and `strtouq' parse integer values from |
| 2228 | strings, like `strtol' and `strtoul', but they return `long long int' and |
| 2229 | `unsigned long long int' values, respectively (64-bit quantities). |
| 2230 | |
| 2231 | * The new functions `strtof' and `strtold' parse floating-point values from |
| 2232 | strings, like `strtod', but they return `float' and `long double' values, |
| 2233 | respectively (on some machines `double' and `long double' are the same). |
| 2234 | |
| 2235 | * Ulrich Drepper has contributed new implementations of the floating-point |
| 2236 | printing and reading code used in the `printf' family of functions and |
| 2237 | `strtod', `strtof', and `strtold'. These new functions are perfectly |
| 2238 | accurate, and much faster than the old ones. |
| 2239 | |
| 2240 | * The implementation of the POSIX locale model was completely rewritten by |
| 2241 | Ulrich Drepper. This includes the new programs `localedef' and `locale' |
| 2242 | to compile the POSIX locale definition. |
| 2243 | |
| 2244 | * The former dummy implementations of the strcoll and strxfrm function are |
| 2245 | now replaced by fully functional code contributed by Ulrich Drepper. The |
| 2246 | collation information comes from the POSIX locale definitions. |
| 2247 | |
| 2248 | * The new header <langinfo.h> defines an interface for accessing |
| 2249 | various locale-dependent data (using the locale chosen with `setlocale'). |
| 2250 | |
| 2251 | * Ulrich Drepper has contributed a new suite of functions for operation on |
| 2252 | wide-character and multibyte-character strings, in <wchar.h>; |
| 2253 | and classification and case conversion of wide characters, in <wctype.h>. |
| 2254 | These new functions are conforming to the ISO C, Amendement 1 specification. |
| 2255 | |
| 2256 | * There is now a second implementation of the standard I/O library available. |
| 2257 | It comes from GNU libg++ as was written by Per Bothner, heavily modified |
| 2258 | by Hongjiu Lu and made thread safe by Ulrich Drepper. |
| 2259 | |
| 2260 | * You can now use positional parameter specifications in format strings |
| 2261 | for the `printf' and `scanf' families of functions. For example, |
| 2262 | `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints |
| 2263 | ``Number 6, Mr Jones''. This is mainly useful when providing different |
| 2264 | format strings for different languages, whose grammars may dictate |
| 2265 | different orderings of the values being printed. To support this |
| 2266 | feature, the interface for `register_printf_handler' has changed; see |
| 2267 | the header file <printf.h> for details. |
| 2268 | |
| 2269 | * The `printf' and `scanf' families of functions now understand a new |
| 2270 | formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says |
| 2271 | to group numbers as indicated by the locale; for `scanf' and friends, this |
| 2272 | says to accept as valid only a number with all the proper grouping |
| 2273 | separators in the right places. In the default "C" locale, numbers are |
| 2274 | not grouped; but locales for specific countries will define the usual |
| 2275 | conventions (i.e. separate thousands with `,' in the US locale). |
| 2276 | |
| 2277 | * The pgrp functions have been regularized, slightly incompatibly but much |
| 2278 | less confusingly. The core functions are now `getpgid' and `setpgid', |
| 2279 | which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no |
| 2280 | argument) and BSD `setpgrp' (identical to `setpgid') functions are |
| 2281 | provided for compatibility. There is no longer an incompatible `getpgrp' |
| 2282 | with an argument declared under _BSD_SOURCE; no BSD code uses it. |
| 2283 | |
| 2284 | * The new header file <fts.h> and suite of functions simplify programs that |
| 2285 | operate on directory trees. This code comes from 4.4 BSD. |
| 2286 | |
| 2287 | * The resolver code has been updated from the BIND 4.9.5-P1 release. |
| 2288 | Parts of the code were heavily modified by Ulrich Drepper to fit in the |
| 2289 | NSS scheme used in glibc. |
| 2290 | |
| 2291 | * There is a new malloc debugging hook `__memalign_hook'. |
| 2292 | |
| 2293 | * There are new typedefs `ushort' for `unsigned short int' and `uint' for |
| 2294 | `unsigned int' in <sys/types.h>. These are for compatibility only and |
| 2295 | their use is discouraged. |
| 2296 | |
| 2297 | * The `-lmcheck' library to enable standard malloc debugging hooks is now |
| 2298 | done differently, so that it works even without GNU ld. |
| 2299 | |
| 2300 | * New function `euidaccess' checks allowed access to a file like `access', |
| 2301 | but using the effective IDs instead of the real IDs. |
| 2302 | |
| 2303 | * The time zone data files have been updated for the latest and greatest |
| 2304 | local time conventions of the countries of the world. |
| 2305 | |
| 2306 | * The new function `dirfd' extracts the file descriptor used by a DIR stream; |
| 2307 | see <dirent.h>. |
| 2308 | |
| 2309 | * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface |
| 2310 | for formatting floating-point numbers. They are provided only for |
| 2311 | compatibility; new programs should use `sprintf' instead. There are |
| 2312 | also equivalent function for the `long double' floating-point type and |
| 2313 | all functions also exist in a reentrant form. |
| 2314 | |
| 2315 | * The new auxiliary library `-lutil' from 4.4 BSD contains various |
| 2316 | functions for maintaining the login-record files (primarily of use to |
| 2317 | system programs such as `login'), and convenient functions for |
| 2318 | allocating and initializing a pseudo-terminal (pty) device. |
| 2319 | |
| 2320 | * Ulrich Drepper has contributed new support for System V style |
| 2321 | shared memory and IPC on systems that support it. |
| 2322 | |
| 2323 | * Ulrich Drepper has contributed several miscellaneous new functions found |
| 2324 | in System V: The `hsearch' family of functions provide an effective |
| 2325 | implementation of hash tables; `a64l' and `l64a' provide a very simple |
| 2326 | binary to ASCII mapping; `drand48' and friends provide a 48-bit random |
| 2327 | number generator. |
| 2328 | |
| 2329 | * Ulrich Drepper has contributed new reentrant counterparts for the |
| 2330 | `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc. |
| 2331 | |
| 2332 | * Ulrich Drepper has contributed new, highly-optimized versions of several |
| 2333 | string functions for the i486/Pentium family of processors. |
| 2334 | |
| 2335 | * Ulrich Drepper has updated the Linux-specific code, based largely |
| 2336 | on work done in Hongjiu Lu's version of GNU libc for Linux. |
| 2337 | The GNU library now supports Linux versions 2.0.10 and later, |
| 2338 | using the ELF object file format (i[3456]86-*-linux). |
| 2339 | |
| 2340 | * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux). |
| 2341 | |
| 2342 | * David Mosberger-Tang and Richard Henderson have ported the C library |
| 2343 | to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the |
| 2344 | dynamic linking support for ELF/Alpha. |
| 2345 | |
| 2346 | * Richard Henderson contributed several Alpha optimized assembler function |
| 2347 | for arithmetic and string handling. |
| 2348 | |
| 2349 | * Ulrich Drepper has contributed a new set of message catalog functions to |
| 2350 | support multiple languages using the <libintl.h> interface, for use with |
| 2351 | his new package GNU gettext. Translation volunteers have contributed |
| 2352 | catalogs of the library's messages in Spanish, German, and Korean. |
| 2353 | |
| 2354 | * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat' |
| 2355 | program and the `catgets' function for reading the catalog files it |
| 2356 | creates. (The <libintl.h> interface is preferred; we include the |
| 2357 | <nl_types.h> interface using `catgets' only for source compatibility with |
| 2358 | programs already written to use it.) |
| 2359 | |
| 2360 | * New header file <values.h> gives SVID-compatible names for <limits.h> |
| 2361 | constants. |
| 2362 | |
| 2363 | * Various new macros, declarations, and small header files for compatibility |
| 2364 | with 4.4 BSD. |
| 2365 | |
| 2366 | * New function `group_member' is a convenient way to check if a process has |
| 2367 | a given effective group ID. |
| 2368 | |
| 2369 | * When using GCC 2.7 and later, the socket functions are now declared in a |
| 2370 | special way so that passing an argument of type `struct sockaddr_in *', |
| 2371 | `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic |
| 2372 | `struct sockaddr *' type, does not generate a type-clash warning. |
| 2373 | |
| 2374 | * New function `error' declared in header file <error.h> is a convenient |
| 2375 | function for printing error messages and optionally exiting; this is the |
| 2376 | canonical function used in GNU programs. The new functions `err', `warn', |
| 2377 | and friends in header file <err.h> are the canonical 4.4 BSD interface for |
| 2378 | doing the same thing. |
| 2379 | |
| 2380 | * The <glob.h> interface has several new flags from 4.4 BSD that extend the |
| 2381 | POSIX.2 `glob' function to do ~ and {...} expansion. |
| 2382 | |
| 2383 | * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD. |
| 2384 | `clearenv' which is used in POSIX.9 is also available. |
| 2385 | |
| 2386 | * New function `getsid' returns session ID number on systems that support it. |
| 2387 | |
| 2388 | * We have incorporated the 4.4 BSD `db' library (version 1.85). New header |
| 2389 | files <db.h> and <mpool.h> provide a rich set of functions for several |
| 2390 | types of simple databases stored in memory and in files, and <ndbm.h> is |
| 2391 | an old `ndbm'-compatible interface using the `db' functions. Link with |
| 2392 | `-ldb' to get these functions. |
| 2393 | |
| 2394 | * New macro `strdupa' copies a string like `strdup', but uses local stack |
| 2395 | space from `alloca' instead of dynamic heap space from `malloc'. |
| 2396 | |
| 2397 | * New function `strnlen' is like `strlen' but searches only a given maximum |
| 2398 | number of characters for the null terminator. `stpncpy', `strndup' and |
| 2399 | `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa' |
| 2400 | function. |
| 2401 | |
| 2402 | * New function `statfs' in header <sys/statfs.h>. |
| 2403 | |
| 2404 | * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader |
| 2405 | provide convenient functions for operating on blocks of null-terminated |
| 2406 | strings. |
| 2407 | |
| 2408 | * A new suite of functions in <utmp.h> handle all the details of reading |
| 2409 | and writing the utmp file. |
| 2410 | |
| 2411 | * An implementation of the NIS/YP(tm) based NSS service was contributed by |
| 2412 | Thorsten Kukuk. |
| 2413 | |
| 2414 | * Paul Eggert and Ulrich Drepper modified the `strftime' function to be |
| 2415 | completely POSIX compliant and also implemented the extended functionality |
| 2416 | to handle alternate digit representation and alternate era date formats. |
| 2417 | |
| 2418 | * Ulrich Drepper provided an implementation of the `strptime' function |
| 2419 | defined in XPG4.2 which transforms a string into a `struct tm' value. |
| 2420 | |
| 2421 | * Paul Eggert provided the tzselect shell script as part of the timezone |
| 2422 | code. The shell script makes it easy to select the correct timezone |
| 2423 | specification. |
| 2424 | |
| 2425 | * The implementation of the malloc family of functions is completely replaced |
| 2426 | by a new implementation by Doug Lea with many improvements by Wolfram Gloger. |
| 2427 | The implementation uses the mmap function (if available) and it is |
| 2428 | optimized for the use in multi threaded programs. |
| 2429 | |
| 2430 | * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of |
| 2431 | functions. This new functionality is usable by specifying a special |
| 2432 | salt string and it is compatible with implementation on *BSD systems. |
| 2433 | |
| 2434 | * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper: |
| 2435 | `getsubopt' to handle second level command line options, `bsd_signal' |
| 2436 | to access BSD style `signal' functionality, the obsolete `regexp' style |
| 2437 | expression matcher. |
| 2438 | |
| 2439 | * the `lchown' function is available on system which support this |
| 2440 | functionality. |
| 2441 | |
| 2442 | * The implementation of the shadow password handling function was contributed |
| 2443 | by Ulrich Drepper. |
| 2444 | |
| 2445 | * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe. |
| 2446 | |
| 2447 | * POSIX.1g support was added. The <sys/select.h> header is available, |
| 2448 | `isfdtype' and `pselect' are implemented. Craig Metz contributed an |
| 2449 | implementation of `getaddrinfo'. |
| 2450 | |
| 2451 | Version 1.09 |
| 2452 | |
| 2453 | * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'. |
| 2454 | |
| 2455 | * New header file <fstab.h> and new functions `getfsspec', `getfsent' and |
| 2456 | friends, for parsing /etc/fstab. This code comes from 4.4 BSD. |
| 2457 | |
| 2458 | * The new function `daemon' from 4.4 BSD is useful for server programs that |
| 2459 | want to put themselves in the background. |
| 2460 | |
| 2461 | * Joel Sherrill has contributed support for several standalone boards that |
| 2462 | run without an operating system. |
| 2463 | |
| 2464 | * `printf', `scanf' and friends now accept a `q' type modifier for long |
| 2465 | long int as well as `ll'. Formats using these might be `%qu' or `%lld'. |
| 2466 | |
| 2467 | * All of the code taken from BSD (notably most of the math and networking |
| 2468 | routines) has been updated from the BSD 4.4-Lite release. |
| 2469 | |
| 2470 | * The resolver code has been updated from the BIND-4.9.3-BETA9 release. |
| 2471 | |
| 2472 | * The new functions `getdomainname' and `setdomainname' fetch or change the |
| 2473 | YP/NIS domain name. These are system calls which exist on systems which |
| 2474 | have YP (aka NIS). |
| 2475 | |
| 2476 | * The time zone data files have been updated for the latest international |
| 2477 | conventions. |
| 2478 | |
| 2479 | * The SunRPC programs `portmap' and `rpcinfo' are now installed in |
| 2480 | $(sbindir) (usually /usr/local/sbin) instead of $(bindir). |
| 2481 | |
| 2482 | Version 1.08 |
| 2483 | |
| 2484 | * The C library now includes support for Sun RPC, from Sun's free |
| 2485 | RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs |
| 2486 | are included. (There is still no support for YP.) |
| 2487 | |
| 2488 | * Tom Quinn has contributed a port of the C library to SGI machines running |
| 2489 | Irix 4 (mips-sgi-irix4). |
| 2490 | |
| 2491 | * The new `lockf' function is a simplified interface to the locking |
| 2492 | facilities of `fcntl', included for compatibility. |
| 2493 | |
| 2494 | * New time functions `timegm', `timelocal', and `dysize' for compatibility. |
| 2495 | |
| 2496 | * New header file <sys/timeb.h> and new function `ftime' for compatibility. |
| 2497 | |
| 2498 | * New header files <poll.h> and <sys/poll.h> and new function `poll' for |
| 2499 | compatibility. |
| 2500 | |
| 2501 | * The error message printed by `assert' for a failed assertion now includes |
| 2502 | the name of the program (if using GNU ld) and the name of the calling |
| 2503 | function (with versions of GCC that support this). |
| 2504 | |
| 2505 | * The `psignal' function is now declared in <signal.h>, not <stdio.h>. |
| 2506 | |
| 2507 | * The library now includes the <sys/mman.h> header file and memory |
| 2508 | management functions `mmap', `munmap', `mprotect', `msync', and |
| 2509 | `madvise', on systems that support those facilities. |
| 2510 | |
| 2511 | * The interface for `mcheck' has changed slightly: the function called to |
| 2512 | abort the program when an allocation inconsistency is detected now takes |
| 2513 | an argument that indicates the type of failure. The new function |
| 2514 | `mprobe' lets you request a consistency check for a particular block at |
| 2515 | any time (checks are normally done only when you call `free' or `realloc' |
| 2516 | on a block). |
| 2517 | |
| 2518 | * It is now possible to easily cross-compile the C library, building on one |
| 2519 | system a library to run on another machine and/or operating system. All |
| 2520 | you need to do is set the variable `HOST_CC' in `configparms' to the |
| 2521 | native compiler for programs to run on the machine you are building on (a |
| 2522 | few generator programs are used on Unix systems); set `CC' to the |
| 2523 | cross-compiler. |
| 2524 | |
| 2525 | * The new function `fexecve' (only implemented on the GNU system) executes |
| 2526 | a program file given a file descriptor already open on the file. |
| 2527 | |
| 2528 | Version 1.07 |
| 2529 | |
| 2530 | * Brendan Kehoe has contributed most of a port to the DEC Alpha |
| 2531 | running OSF/1 (alpha-dec-osf1). He says it is 75% complete. |
| 2532 | |
| 2533 | * You can set the variable `libprefix' in `configparms' to specify a prefix |
| 2534 | to be prepended to installed library files; this makes it easy to install |
| 2535 | the GNU C library to be linked as `-lgnuc' or whatever. |
| 2536 | |
| 2537 | * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It |
| 2538 | copies a limited number of characters from a string, and returns the |
| 2539 | address of the last character written. |
| 2540 | |
| 2541 | * You no longer need to check for whether the installed `stddef.h' is |
| 2542 | compatible with the GNU C library. configure now checks for you. |
| 2543 | |
| 2544 | * You can now define a per-stream `fileno' function to convert the |
| 2545 | stream's cookie into an integral file descriptor. |
| 2546 | |
| 2547 | * ``malloc (0)'' no longer returns a null pointer. Instead, it |
| 2548 | allocates zero bytes of storage, and returns a unique pointer which |
| 2549 | you can pass to `realloc' or `free'. The behavior is undefined if |
| 2550 | you dereference this pointer. |
| 2551 | |
| 2552 | * The C library now runs on Sony NEWS m68k machines running either |
| 2553 | NewsOS 3 or NewsOS 4. |
| 2554 | |
| 2555 | * The new `syscall' function is a system-dependent primitive function |
| 2556 | for invoking system calls. It has the canonical behavior on Unix |
| 2557 | systems, including unreliable return values for some calls (such as |
| 2558 | `pipe', `fork' and `getppid'). |
| 2559 | |
| 2560 | * The error code `EWOULDBLOCK' is now obsolete; it is always defined |
| 2561 | to `EAGAIN', which is the preferred name. On systems whose kernels |
| 2562 | use two distinct codes, the C library now translates EWOULDBLOCK to |
| 2563 | EAGAIN in every system call function. |
| 2564 | |
| 2565 | Version 1.06 |
| 2566 | |
| 2567 | * The GNU C Library Reference Manual is now distributed with the library. |
| 2568 | `make dvi' will produce a DVI file of the printed manual. |
| 2569 | `make info' will produce Info files that you can read on line using C-h i |
| 2570 | in Emacs or the `info' program. |
| 2571 | Please send comments on the manual to bug-glibc-manual@gnu.org. |
| 2572 | |
| 2573 | * The library now supports SVR4 on i386s (i386-unknown-sysv4). |
| 2574 | |
| 2575 | * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2. |
| 2576 | |
| 2577 | * Jason Merrill has contributed a port to the Sequent Symmetry running |
| 2578 | Dynix version 3 (i386-sequent-dynix). |
| 2579 | |
| 2580 | * The library has been ported to i386s running SCO 3.2.4 (also known as SCO |
| 2581 | ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2). |
| 2582 | |
| 2583 | * New function `memory_warnings' lets you arrange to get warnings when |
| 2584 | malloc is running out of memory to allocate, like Emacs gives you. |
| 2585 | |
| 2586 | * The C library now contains the relocating allocator used in Emacs 19 for |
| 2587 | its editing buffers. This allocator (ralloc) minimizes allocation |
| 2588 | overhead and fragmentation by moving allocated regions around whenever it |
| 2589 | needs to. You always refer to a ralloc'd region with a "handle" (a |
| 2590 | pointer to a pointer--an object of type `void **'). |
| 2591 | |
| 2592 | * There is a new `printf' format: `%m' gives you the string corresponding |
| 2593 | to the error code in `errno'. |
| 2594 | |
| 2595 | * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s' |
| 2596 | or `%[' conversion, but instead of filling in a fixed-sized buffer you |
| 2597 | pass, the `a' modifier says to fill in a `char **' you pass with a |
| 2598 | malloc'd string. |
| 2599 | |
| 2600 | * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and |
| 2601 | `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a |
| 2602 | name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching. |
| 2603 | |
| 2604 | * `mkstemp' is a traditional Unix function to atomically create and open a |
| 2605 | uniquely-named temporary file. |
| 2606 | |
| 2607 | Version 1.05 |
| 2608 | |
| 2609 | * The standard location for the file that says what the local timezone is |
| 2610 | has changed again. It is now `/usr/local/etc/localtime' (or more |
| 2611 | precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'. |
| 2612 | |
| 2613 | * The distribution no longer contains any files with names longer than 14 |
| 2614 | characters. |
| 2615 | |
| 2616 | * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE. |
| 2617 | These are set by the new `trusted' and `console' keywords in `/etc/ttys'. |
| 2618 | |
| 2619 | * New functions `ttyslot' and `syslog' from 4.4 BSD. |
| 2620 | |
| 2621 | Version 1.04 |
| 2622 | |
| 2623 | * The configuration process has changed quite a bit. The `configure' |
| 2624 | script is now used just like the configuration scripts for other GNU |
| 2625 | packages. The `sysdeps' directory hierarchy is much rearranged. |
| 2626 | The file `INSTALL' explains the new scheme in detail. |
| 2627 | |
| 2628 | * The header files no longer need to be processed into ANSI C and |
| 2629 | traditional C versions. There is just one set of files to install, and |
| 2630 | it will work with ANSI or old C compilers (including `gcc -traditional'). |
| 2631 | |
| 2632 | * Brendan Kehoe and Ian Lance Taylor have ported the library to the |
| 2633 | MIPS DECStation running Ultrix 4. |
| 2634 | |
| 2635 | * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries. |
| 2636 | Tom Quinn contributed the initial code. The GNU C library can NOT yet be |
| 2637 | made itself into a shared library. |
| 2638 | |
| 2639 | * Yet further improved support for the i386, running 4.3 BSD-like systems |
| 2640 | (such as Mach 3 with the Unix single-server), or System V. |
| 2641 | |
| 2642 | * New function `strncasecmp' to do case-insensitive string comparison |
| 2643 | with limited length. |
| 2644 | |
| 2645 | * New function `strsep' is a reentrant alternative to `strtok'. |
| 2646 | |
| 2647 | * New functions `scandir' and `alphasort' for searching directories. |
| 2648 | |
| 2649 | * New function `setenv' is a better interface to `putenv'. |
| 2650 | |
| 2651 | * Ian Lance Taylor has contributed an implementation of the SVID `ftw' |
| 2652 | function for traversing a directory tree. |
| 2653 | |
| 2654 | * The GNU obstack package is now also part of the C library. |
| 2655 | The new function `open_obstack_stream' creates a stdio stream that |
| 2656 | writes onto an obstack; `obstack_printf' and `obstack_vprintf' do |
| 2657 | formatted output directly to an obstack. |
| 2658 | |
| 2659 | * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only), |
| 2660 | cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid. |
| 2661 | |
| 2662 | * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'. |
| 2663 | |
| 2664 | * The new functions `strfry' and `memfrob' do mysterious and wonderful |
| 2665 | things to your strings. |
| 2666 | |
| 2667 | * There are some new test programs: test-fseek, testmb, and testrand. |
| 2668 | |
| 2669 | * Some work has been done to begin porting the library to 4.4 BSD and Linux. |
| 2670 | These ports are not finished, but are a good starting place for really |
| 2671 | supporting those systems. |
| 2672 | |
| 2673 | * `/etc/localtime' is now the standard location for the file that says what |
| 2674 | the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'. |
| 2675 | This follows the general principle that `/etc' is the place for all local |
| 2676 | configuration files. |
| 2677 | |
| 2678 | * The C library header files now use `extern "C"' when used by the C++ |
| 2679 | compiler, so the C library should now work with C++ code. |
| 2680 | |
| 2681 | * The header file <bstring.h> is gone. <string.h> now declares bcopy, |
| 2682 | bcmp, bzero, and ffs. (Update: nowadays these functions are declared |
| 2683 | in <strings.h>.) |
| 2684 | |
| 2685 | * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting |
| 2686 | function which uses the `merge sort' algorithm, and is said to be |
| 2687 | significantly faster than the old GNU `qsort' function. Merge sort is |
| 2688 | now the standard `qsort' function. The new algorithm can require a lot |
| 2689 | of temporary storage; so, the old sorting function is called when the |
| 2690 | required storage is not available. |
| 2691 | |
| 2692 | * The C library now includes Michael Glad's Ultra Fast Crypt, which |
| 2693 | provides the Unix `crypt' function, plus some other entry points. |
| 2694 | |
| 2695 | * The code and header files taken from 4.4 BSD have been updated with the |
| 2696 | latest files released from Berkeley. |
