The GNU C Library is used as *the* C library in the GNU system and in GNU/Linux systems, as well as many other systems that use Linux as the kernel. The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2008. It is also internationalized and has one of the most complete internationalization interfaces known. The GNU C Library webpage is at http://www.gnu.org/software/libc/ Packages for the 2.28 release may be downloaded from: http://ftpmirror.gnu.org/libc/ http://ftp.gnu.org/gnu/libc/ The mirror list is at http://www.gnu.org/order/ftp.html NEWS for version 2.28 ===================== Major new features: * The localization data for ISO 14651 is updated to match the 2016 Edition 4 release of the standard, this matches data provided by Unicode 9.0.0. This update introduces significant improvements to the collation of Unicode characters. This release deviates slightly from the standard in that the collation element ordering for lowercase and uppercase LATIN script characters is adjusted to ensure that regular expressions with ranges like [a-z] and [A-Z] don't interleave e.g. A is not matched by [a-z]. With the update many locales have been updated to take advantage of the new collation information. The new collation information has increased the size of the compiled locale archive or binary locales. * The GNU C Library can now be compiled with support for Intel CET, AKA Intel Control-flow Enforcement Technology. When the library is built with --enable-cet, the resulting glibc is protected with indirect branch tracking (IBT) and shadow stack (SHSTK). CET-enabled glibc is compatible with all existing executables and shared libraries. This feature is currently supported on i386, x86_64 and x32 with GCC 8 and binutils 2.29 or later. Note that CET-enabled glibc requires CPUs capable of multi-byte NOPs, like x86-64 processors as well as Intel Pentium Pro or newer. NOTE: --enable-cet has been tested for i686, x86_64 and x32 on non-CET processors. --enable-cet has been tested for x86_64 and x32 on CET SDVs, but Intel CET support hasn't been validated for i686. * The GNU C Library now has correct support for ABSOLUTE symbols (SHN_ABS-relative symbols). Previously such ABSOLUTE symbols were relocated incorrectly or in some cases discarded. The GNU linker can make use of the newer semantics, but it must communicate it to the dynamic loader by setting the ELF file's identification (EI_ABIVERSION field) to indicate such support is required. * Unicode 11.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 11.0.0, using generator scripts contributed by Mike FABIAN (Red Hat). * functions that round their results to a narrower type are added from TS 18661-1:2014 and TS 18661-3:2015: - fadd, faddl, daddl and corresponding fMaddfN, fMaddfNx, fMxaddfN and fMxaddfNx functions. - fsub, fsubl, dsubl and corresponding fMsubfN, fMsubfNx, fMxsubfN and fMxsubfNx functions. - fmul, fmull, dmull and corresponding fMmulfN, fMmulfNx, fMxmulfN and fMxmulfNx functions. - fdiv, fdivl, ddivl and corresponding fMdivfN, fMdivfNx, fMxdivfN and fMxdivfNx functions. * Two grammatical forms of month names are now supported for the following languages: Armenian, Asturian, Catalan, Czech, Kashubian, Occitan, Ossetian, Scottish Gaelic, Upper Sorbian, and Walloon. The following languages now support two grammatical forms in abbreviated month names: Catalan, Greek, and Kashubian. * Newly added locales: Lower Sorbian (dsb_DE) and Yakut (sah_RU) also include the support for two grammatical forms of month names. * Building and running on GNU/Hurd systems now works without out-of-tree patches. * The renameat2 function has been added, a variant of the renameat function which has a flags argument. If the flags are zero, the renameat2 function acts like renameat. If the flag is not zero and there is no kernel support for renameat2, the function will fail with an errno value of EINVAL. This is different from the existing gnulib function renameatu, which performs a plain rename operation in case of a RENAME_NOREPLACE flags and a non-existing destination (and therefore has a race condition that can clobber the destination inadvertently). * The statx function has been added, a variant of the fstatat64 function with an additional flags argument. If there is no direct kernel support for statx, glibc provides basic stat support based on the fstatat64 function. * IDN domain names in getaddrinfo and getnameinfo now use the system libidn2 library if installed. libidn2 version 2.0.5 or later is recommended. If libidn2 is not available, internationalized domain names are not encoded or decoded even if the AI_IDN or NI_IDN flags are passed to getaddrinfo or getnameinfo. (getaddrinfo calls with non-ASCII names and AI_IDN will fail with an encoding error.) Flags which used to change the IDN encoding and decoding behavior (AI_IDN_ALLOW_UNASSIGNED, AI_IDN_USE_STD3_ASCII_RULES, NI_IDN_ALLOW_UNASSIGNED, NI_IDN_USE_STD3_ASCII_RULES) have been deprecated. They no longer have any effect. * Parsing of dynamic string tokens in DT_RPATH, DT_RUNPATH, DT_NEEDED, DT_AUXILIARY, and DT_FILTER has been expanded to support the full range of ELF gABI expressions including such constructs as '$ORIGIN$ORIGIN' (if valid). For SUID/GUID applications the rules have been further restricted, and where in the past a dynamic string token sequence may have been interpreted as a literal string it will now cause a load failure. These load failures were always considered unspecified behaviour from the perspective of the dynamic loader, and for safety are now load errors e.g. /foo/${ORIGIN}.so in DT_NEEDED results in a load failure now. * Support for ISO C threads (ISO/IEC 9899:2011) has been added. The implementation includes all the standard functions provided by : - thrd_current, thrd_equal, thrd_sleep, thrd_yield, thrd_create, thrd_detach, thrd_exit, and thrd_join for thread management. - mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, and mtx_destroy for mutual exclusion. - call_once for function call synchronization. - cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, and cnd_wait for conditional variables. - tss_create, tss_delete, tss_get, and tss_set for thread-local storage. Application developers must link against libpthread to use ISO C threads. Deprecated and removed features, and other changes affecting compatibility: * The nonstandard header files and <_G_config.h> are no longer installed. Software that was using either header should be updated to use standard interfaces instead. * The stdio functions 'getc' and 'putc' are no longer defined as macros. This was never required by the C standard, and the macros just expanded to call alternative names for the same functions. If you hoped getc and putc would provide performance improvements over fgetc and fputc, instead investigate using (f)getc_unlocked and (f)putc_unlocked, and, if necessary, flockfile and funlockfile. * All stdio functions now treat end-of-file as a sticky condition. If you read from a file until EOF, and then the file is enlarged by another process, you must call clearerr or another function with the same effect (e.g. fseek, rewind) before you can read the additional data. This corrects a longstanding C99 conformance bug. It is most likely to affect programs that use stdio to read interactive input from a terminal. (Bug #1190.) * The macros 'major', 'minor', and 'makedev' are now only available from the header ; not from or various other headers that happen to include . These macros are rarely used, not part of POSIX nor XSI, and their names frequently collide with user code; see https://sourceware.org/bugzilla/show_bug.cgi?id=19239 for further explanation. is a GNU extension. Portable programs that require these macros should first include , and then include if __GNU_LIBRARY__ is defined. * The tilegx*-*-linux-gnu configurations are no longer supported. * The obsolete function ustat is no longer available to newly linked binaries; the headers and have been removed. This function has been deprecated in favor of fstatfs and statfs. * The obsolete function nfsservctl is no longer available to newly linked binaries. This function was specific to systems using the Linux kernel and could not usefully be used with the GNU C Library on systems with version 3.1 or later of the Linux kernel. * The obsolete function name llseek is no longer available to newly linked binaries. This function was specific to systems using the Linux kernel and was not declared in a header. Programs should use the lseek64 name for this function instead. * The AI_IDN_ALLOW_UNASSIGNED and NI_IDN_ALLOW_UNASSIGNED flags for the getaddrinfo and getnameinfo functions have been deprecated. The behavior previously selected by them is now always enabled. * The AI_IDN_USE_STD3_ASCII_RULES and NI_IDN_USE_STD3_ASCII_RULES flags for the getaddrinfo and getnameinfo functions have been deprecated. The STD3 restriction (rejecting '_' in host names, among other things) has been removed, for increased compatibility with non-IDN name resolution. * The fcntl function now have a Long File Support variant named fcntl64. It is added to fix some Linux Open File Description (OFD) locks usage on non LFS mode. As for others *64 functions, fcntl64 semantics are analogous with fcntl and LFS support is handled transparently. Also for Linux, the OFD locks act as a cancellation entrypoint. * The obsolete functions encrypt, encrypt_r, setkey, setkey_r, cbc_crypt, ecb_crypt, and des_setparity are no longer available to newly linked binaries, and the headers and are no longer installed. These functions encrypted and decrypted data with the DES block cipher, which is no longer considered secure. Software that still uses these functions should switch to a modern cryptography library, such as libgcrypt. * Reflecting the removal of the encrypt and setkey functions above, the macro _XOPEN_CRYPT is no longer defined. As a consequence, the crypt function is no longer declared unless _DEFAULT_SOURCE or _GNU_SOURCE is enabled. * The obsolete function fcrypt is no longer available to newly linked binaries. It was just another name for the standard function crypt, and it has not appeared in any header file in many years. * We have tentative plans to hand off maintenance of the passphrase-hashing library, libcrypt, to a separate development project that will, we hope, keep up better with new passphrase-hashing algorithms. We will continue to declare 'crypt' in , and programs that use 'crypt' or 'crypt_r' should not need to change at all; however, distributions will need to install and libcrypt from a separate project. In this release, if the configure option --disable-crypt is used, glibc will not install or libcrypt, making room for the separate project's versions of these files. The plan is to make this the default behavior in a future release. Changes to build and runtime requirements: GNU make 4.0 or later is now required to build glibc.
