Given the following code: #include <fstream> //or iostream, sstream, istream, ostream struct A { unsigned major; unsigned minor; A(int major, int minor) : major(major), minor(minor){ } }; int main() { A a1(1, 1); return 0; } which is a reduced example from this Stackoverflow queston: http://stackoverflow.com/q/33681093/1708801 Generates the following diagnostics http://melpon.org/wandbox/permlink/Bex1ymr03yuu44Pd: prog.cc:8:5: error: member initializer 'gnu_dev_major' does not name a non-static data member or base class major(major), minor(minor){ } ^~~~~~~~~~~~ /usr/include/x86_64-linux-gnu/sys/sysmacros.h:67:21: note: expanded from macro 'major' # define major(dev) gnu_dev_major (dev) ^~~~~~~~~~~~~~~~~~~ prog.cc:8:19: error: member initializer 'gnu_dev_minor' does not name a non-static data member or base class major(major), minor(minor){ } ^~~~~~~~~~~~ /usr/include/x86_64-linux-gnu/sys/sysmacros.h:68:21: note: expanded from macro 'minor' # define minor(dev) gnu_dev_minor (dev) ^~~~~~~~~~~~~~~~~~~ 2 errors generated. So it looks like the underlying issue is that various stream related headers bring in stdlib.h which eventually casues sys/sysmacros.h to be be included. The details were identified in one of the comments which said: _GNU_SOURCE causes stdlib.h to include sys/types.h, and it causes sys/types.h to include sys/sysmacros.h
I think this is mainly a GCC bug with _GNU_SOURCE being defined by default. See <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=11196>. Avoiding this _GNU_SOURCE definition is hard, because much of the C++ standard library is in the headers and requires functionality outside the ISO C library to implement it. As discussed in <https://sourceware.org/ml/libc-alpha/2012-03/msg00311.html>, we'd be happy to provide a way for libstdc++ to get exactly the interfaces it needs beyond ISO C (at the API and ABI level). But I don't think we've seen further details from the libstdc++ side of exactly what's required. It may be we could also change the _GNU_SOURCE API so that fewer headers result in sys/sysmacros.h being included, but that would need a concrete proposal for an API change on libc-alpha; it's not inherently a bug, so libc-alpha is the right place (followed by a patch there is the API change proposal gets consensus).
https://sourceware.org/ml/libc-alpha/2015-11/msg00253.html
While I agree that defining _GNU_SOURCE from the gcc side is _a_ bug, I think this is also a glibc bug. Individually having stdlib.h include sys/types.h and having sys/types.h include sys/sysmacros.h both make sense as legacy-compat behaviors, but having stdlib.h expose the junk from sys/sysmacros.h is highly undesirable to the point of being a bug. Yes, there should be a concrete API proposal for removing implicit includes like this, but I don't think the need for such a proposal negates classifying this as a bug. My preliminary proposal is that all implicit inclusion of sys/sysmacros.h should be removed. Only a very small number of programs (things like ls, mknod, etc.) have any use at all for these macros and they should be fixed to include it explicitly if they're not already doing so.

With g++ 5 or 6, the C++ library headers don't seem to use <cstdlib> very much anymore, and in particular Shafik's original test case compiles without complaint. It has been agreed that, in some future release, glibc's <sys/types.h> will not include <sys/sysmacros.h> anymore. As of 2.25, it still does, but you get deprecation warnings if you use the macros without including <sys/sysmacros.h>. We have not decided exactly which future release will finally remove the #include; to help us decide, please send reports of software that trips the deprecation warnings to libc-alpha. The warnings currently only happen if you use the macros in function-call context; Shafik's test case, with `#include <cstdlib>` added, does _not_ trigger them, you still get the inexplicable errors. This will hopefully be addressed in a follow-up patch before 2.25 is released.

OK, I changed strace to include <sys/sysmacros.h> unconditionally, but for software portable beyond GNU/Linux there is no workaround available atm.

By using __glibc_macro_warning instead of __attribute_deprecated__, we get the deprecation warnings whenever the macros are expanded, not just when they compile to a function call.

It's also simpler, because __REDIRECT is no longer required. * misc/sys/sysmacros.h (__SYSMACROS_DM, __SYSMACROS_DM1): New macros.

The annotated tag, glibc-2.25 has been created at be176490b818b65b5162c332eb6b581690b16e5c (tag) tagging db0242e3023436757bbc7c488a779e6e3343db04 (commit) replaces glibc-2.24 tagged by Siddhesh Poyarekar on Sun Feb 5 21:19:00 2017 +0530 - Log ----------------------------------------------------------------- The GNU C Library ================= The GNU C Library version 2.25 is now available. 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 2.25 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 2.25 ===================== * The feature test macro __STDC_WANT_LIB_EXT2__, from ISO/IEC TR 24731-2:2010, is supported to enable declarations of functions from that TR. Note that not all functions from that TR are supported by the GNU C Library. * The feature test macro __STDC_WANT_IEC_60559_BFP_EXT__, from ISO/IEC TS 18661-1:2014, is supported to enable declarations of functions and macros from that TS. Note that not all features from that TS are supported by the GNU C Library. * The feature test macro __STDC_WANT_IEC_60559_FUNCS_EXT__, from ISO/IEC TS 18661-4:2015, is supported to enable declarations of functions and macros from that TS. Note that most features from that TS are not supported by the GNU C Library. * The nonstandard feature selection macros _REENTRANT and _THREAD_SAFE are now treated as compatibility synonyms for _POSIX_C_SOURCE=199506L. Since the GNU C Library defaults to a much newer revision of POSIX, this will only affect programs that specifically request an old conformance mode. For instance, a program compiled with -std=c89 -D_REENTRANT will see a change in the visible declarations, but a program compiled with just -D_REENTRANT, or -std=c99 -D_POSIX_C_SOURCE=200809L -D_REENTRANT, will not. Some C libraries once required _REENTRANT and/or _THREAD_SAFE to be defined by all multithreaded code, but glibc has not required this for many years. * The inclusion of <sys/sysmacros.h> by <sys/types.h> is deprecated. This means that in a future release, the macros “major”, “minor”, and “makedev” will only be available from <sys/sysmacros.h>. These macros are not part of POSIX nor XSI, and their names frequently collide with user code; see for instance glibc bug 19239 and Red Hat bug 130601. <stdlib.h> includes <sys/types.h> under _GNU_SOURCE, and C++ code presently cannot avoid being compiled under _GNU_SOURCE, exacerbating the problem. * New <fenv.h> features from TS 18661-1:2014 are added to libm: the fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the femode_t type and the FE_DFL_MODE and FE_SNANS_ALWAYS_SIGNAL macros. * Integer width macros from TS 18661-1:2014 are added to <limits.h>: CHAR_WIDTH, SCHAR_WIDTH, UCHAR_WIDTH, SHRT_WIDTH, USHRT_WIDTH, INT_WIDTH, UINT_WIDTH, LONG_WIDTH, ULONG_WIDTH, LLONG_WIDTH, ULLONG_WIDTH; and to <stdint.h>: INT8_WIDTH, UINT8_WIDTH, INT16_WIDTH, UINT16_WIDTH, INT32_WIDTH, UINT32_WIDTH, INT64_WIDTH, UINT64_WIDTH, INT_LEAST8_WIDTH, UINT_LEAST8_WIDTH, INT_LEAST16_WIDTH, UINT_LEAST16_WIDTH, INT_LEAST32_WIDTH, UINT_LEAST32_WIDTH, INT_LEAST64_WIDTH, UINT_LEAST64_WIDTH, INT_FAST8_WIDTH, UINT_FAST8_WIDTH, INT_FAST16_WIDTH, UINT_FAST16_WIDTH, INT_FAST32_WIDTH, UINT_FAST32_WIDTH, INT_FAST64_WIDTH, UINT_FAST64_WIDTH, INTPTR_WIDTH, UINTPTR_WIDTH, INTMAX_WIDTH, UINTMAX_WIDTH, PTRDIFF_WIDTH, SIG_ATOMIC_WIDTH, SIZE_WIDTH, WCHAR_WIDTH, WINT_WIDTH. * New <math.h> features are added from TS 18661-1:2014: - Signaling NaN macros: SNANF, SNAN, SNANL. - Nearest integer functions: roundeven, roundevenf, roundevenl, fromfp, fromfpf, fromfpl, ufromfp, ufromfpf, ufromfpl, fromfpx, fromfpxf, fromfpxl, ufromfpx, ufromfpxf, ufromfpxl. - llogb functions: the llogb, llogbf and llogbl functions, and the FP_LLOGB0 and FP_LLOGBNAN macros. - Max-min magnitude functions: fmaxmag, fmaxmagf, fmaxmagl, fminmag, fminmagf, fminmagl. - Comparison macros: iseqsig. - Classification macros: iscanonical, issubnormal, iszero. - Total order functions: totalorder, totalorderf, totalorderl, totalordermag, totalordermagf, totalordermagl. - Canonicalize functions: canonicalize, canonicalizef, canonicalizel. - NaN functions: getpayload, getpayloadf, getpayloadl, setpayload, setpayloadf, setpayloadl, setpayloadsig, setpayloadsigf, setpayloadsigl. * The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014, are added to libc. They convert a floating-point number into string. * Most of glibc can now be built with the stack smashing protector enabled. It is recommended to build glibc with --enable-stack-protector=strong. Implemented by Nick Alcock (Oracle). * The function explicit_bzero, from OpenBSD, has been added to libc. It is intended to be used instead of memset() to erase sensitive data after use; the compiler will not optimize out calls to explicit_bzero even if they are "unnecessary" (in the sense that no _correct_ program can observe the effects of the memory clear). * On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined to float instead of double. This does not affect the ABI of any libraries that are part of the GNU C Library, but may affect the ABI of other libraries that use this type in their interfaces. * On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the float_t and double_t types are now defined to long double instead of float and double. These options are not the default, and this does not affect the ABI of any libraries that are part of the GNU C Library, but it may affect the ABI of other libraries that use this type in their interfaces, if they are compiled or used with those options. * The getentropy and getrandom functions, and the <sys/random.h> header file have been added. * The buffer size for byte-oriented stdio streams is now limited to 8192 bytes by default. Previously, on Linux, the default buffer size on most file systems was 4096 bytes (and thus remains unchanged), except on network file systems, where the buffer size was unpredictable and could be as large as several megabytes. * The <sys/quota.h> header now includes the <linux/quota.h> header. Support for the Linux quota interface which predates kernel version 2.4.22 has been removed. * The malloc_get_state and malloc_set_state functions have been removed. Already-existing binaries that dynamically link to these functions will get a hidden implementation in which malloc_get_state is a stub. As far as we know, these functions are used only by GNU Emacs and this change will not adversely affect already-built Emacs executables. Any undumped Emacs executables, which normally exist only during an Emacs build, should be rebuilt by re-running “./configure; make” in the Emacs build tree. * The “ip6-dotint” and “no-ip6-dotint” resolver options, and the corresponding RES_NOIP6DOTINT flag from <resolv.h> have been removed. “no-ip6-dotint” had already been the default, and support for the “ip6-dotint” option was removed from the Internet in 2006. * The "ip6-bytestring" resolver option and the corresponding RES_USEBSTRING flag from <resolv.h> have been removed. The option relied on a backwards-incompatible DNS extension which was never deployed on the Internet. * The flags RES_AAONLY, RES_PRIMARY, RES_NOCHECKNAME, RES_KEEPTSIG, RES_BLAST defined in the <resolv.h> header file have been deprecated. They were already unimplemented. * The "inet6" option in /etc/resolv.conf and the RES_USE_INET6 flag for _res.flags are deprecated. The flag was standardized in RFC 2133, but removed again from the IETF name lookup interface specification in RFC 2553. Applications should use getaddrinfo instead. * DNSSEC-related declarations and definitions have been removed from the <arpa/nameser.h> header file, and libresolv will no longer attempt to decode the data part of DNSSEC record types. Previous versions of glibc only implemented minimal support for the previous version of DNSSEC, which is incompatible with the currently deployed version. * The resource record type classification macros ns_t_qt_p, ns_t_mrr_p, ns_t_rr_p, ns_t_udp_p, ns_t_xfr_p have been removed from the <arpa/nameser.h> header file because the distinction between RR types and meta-RR types is not officially standardized, subject to revision, and thus not suitable for encoding in a macro. * The types res_sendhookact, res_send_qhook, re_send_rhook, and the qhook and rhook members of the res_state type in <resolv.h> have been removed. The glibc stub resolver did not support these hooks, but the header file did not reflect that. * For multi-arch support it is recommended to use a GCC which has been built with support for GNU indirect functions. This ensures that correct debugging information is generated for functions selected by IFUNC resolvers. This support can either be enabled by configuring GCC with '--enable-gnu-indirect-function', or by enabling it by default by setting 'default_gnu_indirect_function' variable for a particular architecture in the GCC source file 'gcc/config.gcc'. * GDB pretty printers have been added for mutex and condition variable structures in POSIX Threads. When installed and loaded in gdb these pretty printers show various pthread variables in human-readable form when read using the 'print' or 'display' commands in gdb. * Tunables feature added to allow tweaking of the runtime for an application program. This feature can be enabled with the '--enable-tunables' configure flag. The GNU C Library manual has details on usage and README.tunables has instructions on adding new tunables to the library. * A new version of condition variables functions have been implemented in the NPTL implementation of POSIX Threads to provide stronger ordering guarantees. * A new version of pthread_rwlock functions have been implemented to use a more scalable algorithm primarily through not using a critical section anymore to make state changes. Security related changes: * On ARM EABI (32-bit), generating a backtrace for execution contexts which have been created with makecontext could fail to terminate due to a missing .cantunwind annotation. This has been observed to lead to a hang (denial of service) in some Go applications compiled with gccgo. Reported by Andreas Schwab. (CVE-2016-6323) * The DNS stub resolver functions would crash due to a NULL pointer dereference when processing a query with a valid DNS question type which was used internally in the implementation. The stub resolver now uses a question type which is outside the range of valid question type values.

As I understand it, the last commit fixed this for 2.28.
That's correct. I did not remember whether one was supposed to close the bug now or leave it open until the release.
This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "GNU C Library master sources". The annotated tag, glibc-2.28 has been created at 0774a9618b539692317d0950477e16a8c5074caf (tag) tagging 3c03baca37fdcb52c3881e653ca392bba7a99c2b (commit) replaces glibc-2.27.9000 tagged by Carlos O'Donell on Wed Aug 1 01:20:23 2018 -0400 - Log ----------------------------------------------------------------- The GNU C Library ================= The GNU C Library version 2.28 is now available. 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). * <math.h> 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 <threads.h>: - 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 <libio.h> and <_G_config.h> are no longer installed. Software that was using either header should be updated to use standard <stdio.h> 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 <sys/sysmacros.h>; not from <sys/types.h> or various other headers that happen to include <sys/types.h>. 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. <sys/sysmacros.h> is a GNU extension. Portable programs that require these macros should first include <sys/types.h>, and then include <sys/sysmacros.h> 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 <ustat.h> and <sys/ustat.h> 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 <rpc/des_crypt.h> and <rpc/rpc_des.h> 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 <unistd.h>, and programs that use 'crypt' or 'crypt_r' should not need to change at all; however, distributions will need to install <crypt.h> and libcrypt from a separate project. In this release, if the configure option --disable-crypt is used, glibc will not install <crypt.h> 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. Security related changes: CVE-2016-6261, CVE-2016-6263, CVE-2017-14062: Various vulnerabilities have been fixed by removing the glibc-internal IDNA implementation and using the system-provided libidn2 library instead. Originally reported by Hanno Böck and Christian Weisgerber. CVE-2017-18269: An SSE2-based memmove implementation for the i386 architecture could corrupt memory. Reported by Max Horn. CVE-2018-11236: Very long pathname arguments to realpath function could result in an integer overflow and buffer overflow. Reported by Alexey Izbyshev. CVE-2018-11237: The mempcpy implementation for the Intel Xeon Phi architecture could write beyond the target buffer, resulting in a buffer overflow. Reported by Andreas Schwab.
