As the Summary says. glibc has many internal sockets that it opens for internal operations and doesn't use SOCK_CLOEXEC on. Some of those sockets are used only for a short time (for ioctl or netlink), but some may be for a long time. Anyway, however short the time it stays open, there's still a chance that it may leak by another thread doing a simultaneous fork(). I've found socket openings without SOCK_CLOEXEC in: * __opensock (socket/opensock.c), though the override in sysdeps/unix/sysv/linux/opensock.c uses SOCK_CLOEXEC * getifaddrs (sysdeps/gnu/ifaddrs.c and sysdeps/unix/sysv/linux/ifaddrs.c) * getaddrinfo (sysdeps/posix/getaddrinfo.c) * __check_native (sysdeps/unix/sysv/linux/check_native.c) * __check_pf (sysdeps/unix/sysv/linux/check_pf.c) * multiple in resolv/res_send.c There could be more. Maybe it would be useful to have an internal function that opens always a socket with O_CLOEXEC semantics.
Could you prepare a patch that fixes these?
I'm sorry, I'm not qualified to do that under glibc coding style. I don't even understand how the buildsystem works, so I can't tell which files are relevant or not.
A most work here is clasifying which files are internal and which not. A sample list could be generated by: git grep ' open (' | grep '\.c' | grep -v '\(tst\|bug\)' git grep ' fopen (' | grep '\.c' | grep -v '\(tst\|bug\)' But somebody needs to go througth this and filter entries with clockexec or these passed to user code.
I respectfully submit that glibc opening files without FD_CLOEXEC is a bug, as it makes quite a few of the functions thread-unsafe. This issue should be changed from "enhancement" to "normal".
This could cause security issues if a critical descriptor leaks to child processes.

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-2.26 has been created at ef82e26a1d7247c6b0b85e27880113a7690af64d (tag) tagging 1c9a5c270d8b66f30dcfaf1cb2d6cf39d3e18369 (commit) replaces glibc-2.25 tagged by Siddhesh Poyarekar on Wed Aug 2 19:12:20 2017 +0530 - Log ----------------------------------------------------------------- FROM: Siddhesh Poyarekar <siddhesh@sourceware.org> SUBJECT: The GNU C Library version 2.26 is now available The GNU C Library ================= The GNU C Library version 2.26 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 2.26 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 2.26 ===================== Major new features: * A per-thread cache has been added to malloc. Access to the cache requires no locks and therefore significantly accelerates the fast path to allocate and free small amounts of memory. Refilling an empty cache requires locking the underlying arena. Performance measurements show significant gains in a wide variety of user workloads. Workloads were captured using a special instrumented malloc and analyzed with a malloc simulator. Contributed by DJ Delorie with the help of Florian Weimer, and Carlos O'Donell. * Unicode 10.0.0 Support: Character encoding, character type info, and transliteration tables are all updated to Unicode 10.0.0, using generator scripts contributed by Mike FABIAN (Red Hat). These updates cause user visible changes, especially the changes in wcwidth for many emoji characters cause problems when emoji sequences are rendered with pango, see for example: https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5 * Collation of Hungarian has been overhauled and is now consistent with "The Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by Egmont Koblinger. * Improvements to the DNS stub resolver, contributed by Florian Weimer: - The GNU C Library will now detect when /etc/resolv.conf has been modified and reload the changed configuration. The new resolver option “no-reload” (RES_NORELOAD) disables this behavior. - The GNU C Library now supports an arbitrary number of search domains (configured using the “search” directive in /etc/resolv.conf); previously, there was a hard limit of six domains. For backward compatibility, applications that directly modify the ‘_res’ global object are still limited to six search domains. - When the “rotate” (RES_ROTATE) resolver option is active, the GNU C Library will now randomly pick a name server from the configuration as a starting point. (Previously, the second name server was always used.) * The tunables feature is now enabled by default. This allows users to tweak behavior of the GNU C Library using the GLIBC_TUNABLES environment variable. * New function reallocarray, which resizes an allocated block (like realloc) to the product of two sizes, with a guaranteed clean failure upon integer overflow in the multiplication. Originally from OpenBSD, contributed by Dennis Wölfing and Rüdiger Sonderfeld. * New wrappers for the Linux-specific system calls preadv2 and pwritev2. These are extended versions of preadv and pwritev, respectively, taking an additional flags argument. The set of supported flags depends on the running kernel; full support currently requires kernel 4.7 or later. * posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to create a new session ID for the spawned process. This feature is scheduled to be added to the next major revision of POSIX; for the time being, it is available under _GNU_SOURCE. * errno.h is now safe to use from C-preprocessed assembly language on all supported operating systems. In this context, it will only define the Exxxx constants, as preprocessor macros expanding to integer literals. * On ia64, powerpc64le, x86-32, and x86-64, the math library now implements 128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE 754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy, Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers. To compile programs that use this feature, the compiler must support 128-bit floating point with the type name _Float128 (as defined by TS 18661-3) or __float128 (the nonstandard name used by GCC for C++, and for C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__ must be defined to make the new interfaces visible. The new functions and macros correspond to those present for other floating-point types (except for a few obsolescent interfaces not supported for the new type), with F128 or f128 suffixes; for example, strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no printf or scanf formats for the new type; the strfromf128 and strtof128 interfaces should be used instead. Deprecated and removed features, and other changes affecting compatibility: * The synchronization that pthread_spin_unlock performs has been changed to now be equivalent to a C11 atomic store with release memory order to the spin lock's memory location. Previously, several (but not all) architectures used stronger synchronization (e.g., containing what is often called a full barrier). This change can improve performance, but may affect odd fringe uses of spin locks that depend on the previous behavior (e.g., using spin locks as atomic variables to try to implement Dekker's mutual exclusion algorithm). * The port to Native Client running on ARMv7-A (--host=arm-nacl) has been removed. * Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers will only be built and installed when the GNU C Library is configured with --enable-obsolete-rpc. This allows alternative RPC implementations, such as TIRPC or rpcsvc-proto, to be used. * The NIS(+) name service modules, libnss_nis, libnss_nisplus, and libnss_compat, are deprecated, and will not be built or installed by default. The NIS(+) support library, libnsl, is also deprecated. By default, a compatibility shared library will be built and installed, but not headers or development libraries. Only a few NIS-related programs require this library. (In particular, the GNU C Library has never required programs that use 'gethostbyname' to be linked with libnsl.) Replacement implementations based on TIRPC, which additionally support IPv6, are available from <https://github.com/thkukuk/>. The configure option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+) name service modules, to be built and installed. * The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC support is enabled, the configured recursive resolver must support EDNS. (Responding to EDNS-enabled queries with responses which are not EDNS-enabled is fine, but FORMERR responses are not.) * res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS servers have not supported this opcode for a long time. * The _res_opcodes variable has been removed from libresolv. It had been exported by accident. * <string.h> no longer includes inline versions of any string functions, as this kind of optimization is better done by the compiler. The macros __USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect. * The nonstandard header <xlocale.h> has been removed. Most programs should use <locale.h> instead. If you have a specific need for the definition of locale_t with no other declarations, please contact libc-alpha@sourceware.org and explain. * The obsolete header <sys/ultrasound.h> has been removed. * The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>. * The obsolete function cfree has been removed. Applications should use free instead. * The stack_t type no longer has the name struct sigaltstack. This changes the C++ name mangling for interfaces involving this type. * The ucontext_t type no longer has the name struct ucontext. This changes the C++ name mangling for interfaces involving this type. * On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no longer has the name struct mcontext. On SPARC GNU/Linux, the struct mc_fq, struct rwindow, struct fpq and struct fq types are no longer defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct mc_fpu, the gwindows_t type no longer has the name struct gwindows and the fpregset_t type no longer has the name struct fpu. This changes the C++ name mangling for interfaces involving those types. * On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been synced with the kernel: - PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS are not supported on this architecture and have been removed. - PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added. Programs that assume the GET/SETREGS ptrace requests are universally available will now fail to build, instead of malfunctioning at runtime. Changes to build and runtime requirements: * Linux kernel 3.2 or later is required at runtime, on all architectures supported by that kernel. (This is a change from version 2.25 only for x86-32 and x86-64.) * GNU Binutils 2.25 or later is now required to build the GNU C Library. * On most architectures, GCC 4.9 or later is required to build the GNU C Library. On powerpc64le, GCC 6.2 or later is required. Older GCC versions and non-GNU compilers are still supported when compiling programs that use the GNU C Library. (We do not know exactly how old, and some GNU extensions to C may be _de facto_ required. If you are interested in helping us make this statement less vague, please contact libc-alpha@sourceware.org.) Security related changes: * The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes, to avoid fragmentation-based spoofing attacks (CVE-2017-12132). * LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE mode to guard against local privilege escalation attacks (CVE-2017-1000366). * Avoid printing a backtrace from the __stack_chk_fail function since it is called on a corrupt stack and a backtrace is unreliable on a corrupt stack (CVE-2010-3192). * A use-after-free vulnerability in clntudp_call in the Sun RPC system has been fixed (CVE-2017-12133).

I believe with commit 3fe8fc793f2e98c28c07428fabdeaf2f3c3480c7, the Linux side should be fixed now.
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.
