Hi: Recently a getrandom() system call was added to the linux kernel http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=c6e9d6f38894798696f23c8084ca7edbf16ee895 Please add the relevant system call wrappers to glibc under _GNU_SOURCE guard and a getentropy() wrapper under _BSD_SOURCE for compatibility. Ideally, if the system call is not found in the running kernel, fallback to emulation by reading /dev/urandom in the default case or /dev/random if GRND_RANDOM is used.
If you wish to propose a new API for glibc, please make the proposal on libc-alpha, taking an active lead in driving the discussion to consensus.

If GRND_NONBLOCK is not set and the buffer is proper, the system call cannot fail. It is impossible to achieve that with emulation.
Any progress on this issue? I would be interested to use it in Python to avoid issues with the /dev/urandom file descriptor: http://bugs.python.org/issue22181
(In reply to Victor Stinner from comment #3) > Any progress on this issue? I would be interested to use it in Python to > avoid issues with the /dev/urandom file descriptor: > http://bugs.python.org/issue22181 use the syscall() interface for now.
If you want progress on this, take a lead in the general discussion on libc-alpha of when glibc should provide bindings to Linux kernel syscalls, seeking to understand the differences of views expressed, find common ground and drive the discussion to consensus. Once we have agreed principles on bindings for syscalls, then we can consider which new or old syscalls should have such bindings added under those principles.
There is a very long and interesting discussion at the thread above that is very high level, but there is nothing to the point for this API. At the moment the Linux kernel offers a new system call getrandom() which solves several problems of /dev/urandom approach (see [0] for some affecting gnutls), but userspace cannot access it in reasonable way. syscall() is not a reasonable way. To clarify; until now userspace is using autoconf macros to detect capabilities, e.g., a function in libc, libwhatever. With the approach of having useful kernel calls which don't map to libc we are unfortunately breaking this detection and forcing them to do some compile/runtime detection of system calls(?). That's pretty ugly. My suggestion would be for glibc to duplicate the OpenBSD API [1], and not provide any API for kernels without this capability (you can't duplicate these semantics). The whole reason, for this system call is that the semantics of /dev/urandom were too unreliable to simulate a getrandom() function. Nevertheless, I wouldn't object in any other solution which brings the system call. I just believe that this system call to is too good to ignore for so long.

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.
