Description
Thiago Macieira
2013-07-09 03:08:35 UTC
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".

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).

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.
