GNU C Library NEWS -- history of user-visible changes.
Copyright (C) 1992-2024 Free Software Foundation, Inc.
See the end for copying conditions.
Please send GNU C library bug reports via <https://sourceware.org/bugzilla/>
using `glibc' in the "product" field.
Version 2.40
Major new features:
* The <stdbit.h> header type-generic macros have been changed when using
GCC 14.1 or later to use __builtin_stdc_bit_ceil etc. built-in functions
in order to support unsigned __int128 and/or unsigned _BitInt(N) operands
with arbitrary precisions when supported by the target.
* The GNU C Library now supports a feature test macro _ISOC23_SOURCE to
enable features from the ISO C23 standard. Only some features from
this standard are supported by the GNU C Library. The older name
_ISOC2X_SOURCE is still supported. Features from C23 are also enabled
by _GNU_SOURCE, or by compiling with the GCC options -std=c23,
-std=gnu23, -std=c2x or -std=gnu2x.
* A new tunable, glibc.rtld.enable_secure, used to run a program
as if it were a setuid process. This is currently a testing tool to allow
more extensive verification tests for AT_SECURE programs and not meant to
be a security feature.
Deprecated and removed features, and other changes affecting compatibility:
[Add deprecations, removals and changes affecting compatibility here]
Changes to build and runtime requirements:
[Add changes to build and runtime requirements here]
Security related changes:
The following CVEs were fixed in this release, details of which can be
found in the advisories directory of the release tarball:
[The release manager will add the list generated by
scripts/process-advisories.sh just before the release.]
The following bugs are resolved with this release:
[The release manager will add the list generated by
scripts/list-fixed-bugs.py just before the release.]
Version 2.39
Major new features:
* A new tunable, glibc.cpu.plt_rewrite, can be used to enable PLT
rewrite on x86-64. When enabled with non-lazy binding, the dynamic
linker will rewrite indirect branches in PLT with direct branches.
* Sync with Linux kernel 6.6 shadow stack interface. The --enable-cet
configure option is only supported on x86-64.
* struct statvfs now has an f_type member, equal to the f_type statfs member;
on the Hurd this was always available under a reserved name,
and under Linux a spare has been allocated: it was always zero
in previous versions of glibc, and zero is not a valid result.
* On Linux, the functions posix_spawnattr_getcgroup_np and
posix_spawnattr_setcgroup_np have been added, along with the
POSIX_SPAWN_SETCGROUP flag. They allow posix_spawn and posix_spawnp
to set the cgroupv2 in the new process in a race-free manner. These
functions are GNU extensions and require a kernel with clone3 support.
* On Linux, the pidfd_spawn and pidfd_spawp functions have been added.
They have a similar prototype and semantic as posix_spawn, but instead of
returning a process ID, they return a file descriptor that can be used
along other pidfd functions (like pidfd_send_signal, poll, or waitid).
The pidfd functionality avoids the issue of PID reuse with the traditional
posix_spawn interface.
* On Linux, the pidfd_getpid function has been added. It allows retrieving
the process ID associated with the process file descriptor created by
pid_spawn, fork_np, or pidfd_open.
* scanf-family functions now support the wN format length modifiers for
arguments pointing to types intN_t, int_leastN_t, uintN_t or
uint_leastN_t (for example, %w32d to read int32_t or int_least32_t in
decimal, or %w32x to read uint32_t or uint_least32_t in hexadecimal)
and the wfN format length modifiers for arguments pointing to types
int_fastN_t or uint_fastN_t, as specified in draft ISO C2X.
* A new tunable, glibc.mem.decorate_maps, can be used to add additional
information on underlying memory allocated by the glibc (for instance,
on thread stack created by pthread_create or memory allocated by
malloc).
* The <stdbit.h> header has been added from ISO C2X, with
stdc_leading_zeros, stdc_leading_ones, stdc_trailing_zeros,
stdc_trailing_ones, stdc_first_leading_zero, stdc_first_leading_one,
stdc_first_trailing_zero, stdc_first_trailing_one, stdc_count_zeros,
stdc_count_ones, stdc_has_single_bit, stdc_bit_width, stdc_bit_floor
and stdc_bit_ceil function families, each having functions for
unsigned char, unsigned short, unsigned int, unsigned long int and
unsigned long long int, and a type-generic macro.
* On AArch64 new symbols were added to libmvec and now math.h has
annotations to allow GCC 9 or newer to auto-vectorize calls to the
following scalar math functions when -ffast-math is specified:
acos, acosf, asin, asinf, atan, atanf, atan2, atan2f, cos, cosf,
exp, expf, exp10, exp10f, exp2, exp2f, expm1, expm1f, log, logf,
log10, log10f, log1p, log1pf, log2, log2f, sin, sinf, tan, tanf.
Deprecated and removed features, and other changes affecting compatibility:
* The ldconfig program now skips file names containing ';' or ending in
".dpkg.tmp" or ".dpkg.new", to avoid examining temporary files created
by the RPM and dpkg package managers.
* libcrypt has been removed from the GNU C Library. The configure
options "--enable-crypt" and "--enable-nss-crypt" are no longer
available. <crypt.h>, libcrypt.a, and libcrypt.so.1 will not be
installed. For now <unistd.h> continues to declare the crypt
function by default, to avoid introducing vulnerabilities into
existing applications due to a missing prototype. This declaration
is deprecated and may be removed in a future glibc release.
The replacement for libcrypt is libxcrypt, maintained separately from
GNU libc, but available under compatible licensing terms, and providing
binary backward compatibility with the former libcrypt. It is currently
distributed from <https://github.com/besser82/libxcrypt/>.
As a consequence of this removal, GNU libc no longer makes any use of
the NSS cryptography library (Network Security Services; not to be
confused with Name Service Switch). Distributors of binary packages
of GNU libc are advised to check whether their build processes can be
simplified.
* The dynamic linker calls the malloc and free functions in more cases
during TLS access if a shared object with dynamic TLS is loaded and
unloaded. This can result in an infinite recursion if a malloc
replacement library or its dependencies use dynamic TLS instead of
initial-exec TLS.
* The ia64*-*-linux-gnu configurations are no longer supported.
Changes to build and runtime requirements:
* Building on LoongArch requires at a minimum binutils 2.41 for vector
instructions.

Version 2.38
Major new features:
* When C2X features are enabled and the base argument is 0 or 2, the
following functions support binary integers prefixed by 0b or 0B as
input: strtol, strtoll, strtoul, strtoull, strtol_l, strtoll_l,
strtoul_l, strtoull_l, strtoimax, strtoumax, strtoq, strtouq, wcstol,
wcstoll, wcstoul, wcstoull, wcstol_l, wcstoll_l, wcstoul_l,
wcstoull_l, wcstoimax, wcstoumax, wcstoq, wcstouq. Similarly, the
following functions support binary integers prefixed by 0b or 0B as
input to the %i format: fscanf, scanf, sscanf, vscanf, vsscanf,
vfscanf, fwscanf, wscanf, swscanf, vfwscanf, vwscanf, vswscanf; those
functions also support the %b format for binary integers, with or
without such a prefix and independent of standards mode.
* PRIb*, PRIB* and SCNb* macros from C2X have been added to
<inttypes.h>.
* printf-family functions now support the wN format length modifiers for
arguments of type intN_t, int_leastN_t, uintN_t or uint_leastN_t (for
example, %w32d to print int32_t or int_least32_t in decimal, or %w32x
to print uint32_t or uint_least32_t in hexadecimal) and the wfN format
length modifiers for arguments of type int_fastN_t or uint_fastN_t, as
specified in draft ISO C2X.
* A new tunable, glibc.pthread.stack_hugetlb, can be used to disable
Transparent Huge Pages (THP) in stack allocation at pthread_create.
* Support for x86_64 running on Hurd has been added. This port requires
as least binutils 2.40 and GCC 13:
- x86_64-gnu
* Vector math library libmvec support has been added to AArch64. It
requires GCC version >= 10.1.0. It can be disabled via
"--disable-mathvec", however that is not a supported configuration as
it changes the ABI. The symbol names follow the AArch64 vector ABI,
they are declared in math.h and have to be called manually at this point.
* The strlcpy and strlcat functions have been added. They are derived
from OpenBSD, and are expected to be added to a future POSIX version.
* A new configure option, "--enable-fortify-source", can be used to build the
GNU C Library with _FORTIFY_SOURCE. The level of fortification can either be
provided, or is set to the highest value supported by the compiler. If not
explicitly enabled, then fortify source is forcibly disabled so to keep
original behavior unchanged.
Deprecated and removed features, and other changes affecting compatibility:
* libcrypt is no longer built by default; one may use the "--enable-crypt"
option to build libcrypt. libcrypt is likely to be removed from the
GNU C Library in a future release, so it is recommended that
applications port away from it to an alternative such as libxcrypt.
* In the Linux kernel for the hppa/parisc architecture some of the
MADV_XXX constants were changed to have the same values as the other
architectures. New programs compiled with this glibc version and which
use the madvise call will require at least Linux kernel version 6.2,
alternatively stable kernels from versions 6.1.6, 5.15.87, 5.10.163,
5.4.228, 4.19.270 or 4.14.303.
* The "--disable-experimental-malloc" option is no longer available. The
per-thread cache can still be disabled per-application using tunables
(glibc.malloc.tcache_count set to zero).
* The configure option "--enable-tunables" has been removed. The tunable
feature is now always enabled.
Changes to build and runtime requirements:
* Building libmvec on AArch64 requires at a minimum GCC 10.1.0 for SVE
ACLE.
Security related changes:
CVE-2023-25139: When the printf family of functions is called with a
format specifier that uses an <apostrophe> (enable grouping) and a
minimum width specifier, the resulting output could be larger than
reasonably expected by a caller that computed a tight bound on the
buffer size. The resulting larger than expected output could result
in a buffer overflow in the printf family of functions.
The following bugs are resolved with this release:
[178] string: Please add strlcpy and strlcat (attached)
[14697] nptl: Behavior of exit is nonconformant with respect to

Version 2.37
Major new features:
* The getent tool now supports the --no-addrconfig option. The output of
getent with --no-addrconfig may contain addresses of families not
configured on the current host i.e. as-if you had not passed
AI_ADDRCONFIG to getaddrinfo calls.
Deprecated and removed features, and other changes affecting compatibility:
* The dynamic linker no longer loads shared objects from the "tls"
subdirectories on the library search path or the subdirectory that
corresponds to the AT_PLATFORM system name, or employs the legacy AT_HWCAP
search mechanism, which was deprecated in version 2.33.
Security related changes:
CVE-2022-39046: When the syslog function is passed a crafted input
string larger than 1024 bytes, it reads uninitialized memory from the
heap and prints it to the target log file, potentially revealing a
portion of the contents of the heap.

Version 2.36
Major new features:
* Support for DT_RELR relative relocation format has been added to
glibc. This is a new ELF dynamic tag that improves the size of
relative relocations in shared object files and position independent
executables (PIE). DT_RELR generation requires linker support for
-z pack-relative-relocs option, which is supported for some targets
in recent binutils versions. Lazy binding doesn't apply to DT_RELR.
* On Linux, the pidfd_open, pidfd_getfd, and pidfd_send_signal functions
have been added. The pidfd functionality provides access to a process
while avoiding the issue of PID reuse on traditional Unix systems.
* On Linux, the process_madvise function has been added. It has the
same functionality as madvise but alters the target process identified
by the pidfd.
* On Linux, the process_mrelease function has been added. It allows a
caller to release the memory of a dying process. The release of the
memory is carried out in the context of the caller, using the caller's
CPU affinity, and priority with CPU usage accounted to the caller.
* The “no-aaaa” DNS stub resolver option has been added. System
administrators can use it to suppress AAAA queries made by the stub
resolver, including AAAA lookups triggered by NSS-based interfaces
such as getaddrinfo. Only DNS lookups are affected: IPv6 data in
/etc/hosts is still used, getaddrinfo with AI_PASSIVE will still
produce IPv6 addresses, and configured IPv6 name servers are still
used. To produce correct Name Error (NXDOMAIN) results, AAAA queries
are translated to A queries. The new resolver option is intended
primarily for diagnostic purposes, to rule out that AAAA DNS queries
have adverse impact. It is incompatible with EDNS0 usage and DNSSEC
validation by applications.
* On Linux, the fsopen, fsmount, move_mount, fsconfig, fspick, open_tree,
and mount_setattr have been added. They are part of the new Linux kernel
mount APIs that allow applications to more flexibly configure and operate
on filesystem mounts. The new mount APIs are specifically designed to work
with namespaces.
* localedef now accepts locale definition files encoded in UTF-8.
Previously, input bytes not within the ASCII range resulted in
unpredictable output.
* Support for the mbrtoc8 and c8rtomb multibyte/UTF-8 character conversion
functions has been added per the ISO C2X N2653 and C++20 P0482R6 proposals.
Support for the char8_t typedef has been added per the ISO C2X N2653
proposal. The functions are declared in uchar.h in C2X mode or when the
_GNU_SOURCE macro or C++20 __cpp_char8_t feature test macro is defined.
The char8_t typedef is declared in uchar.h in C2X mode or when the
_GNU_SOURCE macro is defined and the C++20 __cpp_char8_t feature test macro
is not defined (if __cpp_char8_t is defined, then char8_t is a builtin type).
* The functions arc4random, arc4random_buf, and arc4random_uniform have been
added. The functions wrap getrandom and/or /dev/urandom to return high-
quality randomness from the kernel.
* Support for LoongArch running on Linux has been added. This port requires
as least binutils 2.38, GCC 12, and Linux 5.19. Currently only hard-float
ABI is supported:
- loongarch64-linux-gnu
The LoongArch ABI is 64-bit little-endian.
Deprecated and removed features, and other changes affecting compatibility:
* Support for prelink will be removed in the next release; this includes
removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
variables and their functionality in the dynamic loader.
* The Linux kernel version check has been removed along with the
LD_ASSUME_KERNEL environment variable. The minimum kernel used to built
glibc is still provided through NT_GNU_ABI_TAG ELF note and also printed
when libc.so is issued directly.
* On Linux, The LD_LIBRARY_VERSION environment variable has been removed.

Version 2.35
Major new features:
* Unicode 14.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 14.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
* Bump r_version in the debugger interface to 2 and add a new field,
r_next, support multiple namespaces.
* Support for the C.UTF-8 locale has been added to glibc. The locale
supports full code-point sorting for all valid Unicode code points. A
limitation in the framework for fnmatch, regexec, and regcomp requires
a compromise to save space and only ASCII-based range expressions are
supported for now (see bug 28255). The full size of the locale is
only ~400KiB, with 346KiB coming from LC_CTYPE information for
Unicode. This locale harmonizes downstream C.UTF-8 already shipping
in various downstream distributions. The locale is not built into
glibc, and must be installed.
* <math.h> functions that round their results to a narrower type, and
corresponding <tgmath.h> macros, are added from TS 18661-1:2014, TS
18661-3:2015 and draft ISO C2X:
- fsqrt, fsqrtl, dsqrtl and corresponding fMsqrtfN, fMsqrtfNx,
fMxsqrtfN and fMxsqrtfNx functions.
- ffma, ffmal, dfmal and corresponding fMfmafN, fMfmafNx, fMxfmafN and
fMxfmafNx functions.
* <math.h> functions for floating-point maximum and minimum,
corresponding to new operations in IEEE 754-2019, and corresponding
<tgmath.h> macros, are added from draft ISO C2X: fmaximum,
fmaximum_num, fmaximum_mag, fmaximum_mag_num, fminimum, fminimum_num,
fminimum_mag, fminimum_mag_num and corresponding functions for float,
long double, _FloatN and _FloatNx.
* <math.h> macros for single-precision float constants are added as a
GNU extension: M_Ef, M_LOG2Ef, M_LOG10Ef, M_LN2f, M_LN10f, M_PIf,
M_PI_2f, M_PI_4f, M_1_PIf, M_2_PIf, M_2_SQRTPIf, M_SQRT2f and
M_SQRT1_2f.
* The __STDC_IEC_60559_BFP__ and __STDC_IEC_60559_COMPLEX__ macros are
predefined as specified in TS 18661-1:2014.
* The exp10 functions in <math.h> now have a corresponding type-generic
macro in <tgmath.h>.
* The ISO C2X macro _PRINTF_NAN_LEN_MAX has been added to <stdio.h>.
* printf-family functions now support the %b format for output of
integers in binary, as specified in draft ISO C2X, and the %B variant
of that format recommended by draft ISO C2X.
* A new DSO sorting algorithm has been added in the dynamic linker that uses
topological sorting by depth-first search (DFS), solving performance issues
of the existing sorting algorithm when encountering particular circular
object dependency cases.
* A new tunable, glibc.rtld.dynamic_sort, can be used to select between
the two DSO sorting algorithms. The default setting of '2' uses the
new DFS-based algorithm. The setting '1' switches to the old
algorithm used in glibc 2.33 and earlier.
* ABI support for a new function '__memcmpeq'. '__memcmpeq' is meant
to be used by compilers for optimizing usage of 'memcmp' when its
return value is only used for its boolean status.
* Support for automatically registering threads with the Linux rseq
system call has been added. This system call is implemented starting
from Linux 4.18. The Restartable Sequences ABI accelerates user-space
operations on per-cpu data. It allows user-space to perform updates
on per-cpu data without requiring heavy-weight atomic operations.
Automatically registering threads allows all libraries, including
libc, to make immediate use of the rseq support by using the
documented ABI, via the __rseq_flags, __rseq_offset, and __rseq_size
variables. The GNU C Library manual has details on integration of
Restartable Sequences.
* A symbolic link to the dynamic linker is now installed under
/usr/bin/ld.so (or more precisely, '${bindir}/ld.so').
* All programs and the testsuite in glibc are now built as position independent
executables (PIE) by default on toolchains and architectures that support it.
Further, if the toolchain and architecture supports it, even static programs
are built as PIE and the resultant glibc can be used to build static PIE
executables. A new option --disable-default-pie has been added to disable
this behavior and get a non-PIE build. This option replaces
--enable-static-pie, which no longer has any effect on the build
configuration.
* On Linux, a new tunable, glibc.malloc.hugetlb, can be used to
either make malloc issue madvise plus MADV_HUGEPAGE on mmap and sbrk
or to use huge pages directly with mmap calls with the MAP_HUGETLB
flags). The former can improve performance when Transparent Huge Pages
is set to 'madvise' mode while the latter uses the system reserved
huge pages.
* The printf family of functions now handles the flagged %#m conversion
specifier, printing errno as an error constant (similar to strerrorname_np).
* The function _dl_find_object has been added. In-process unwinders
can use it to efficiently locate unwinding information for a code
address.
* Support for OpenRISC running on Linux has been added. This port requires
as least binutils 2.35, GCC 11, and Linux 5.4. Currently only soft-float
ABI is supported:
- or1k-linux-gnu
The OpenRISC ABI is 32-bit big-endian and uses 64-bit time (y2038 safe) and
64-bit file offsets (LFS default).
* A new configure option, --with-rtld-early-cflags, can be used to
specify additional compiler flags for building the early startup code
of the dynamic linker. On targets which have CPU compatibility
checks, this can help to ensure that proper diagnostics are printed if
the dynamic loader runs on an incompatible CPU.
* On Linux, the epoll_pwait2 function has been added. It is similar to
epoll_wait with the difference the timeout has nanoseconds resolution.
* The function posix_spawn_file_actions_addtcsetpgrp_np has been added,
enabling posix_spawn and posix_spawnp to set the controlling terminal in
the new process in a race free manner. This function is a GNU extension.
* Source fortification (_FORTIFY_SOURCE) level 3 is now available for
applications compiling with glibc and gcc 12 and later. Level 3 leverages
the __builtin_dynamic_object_size function to deliver additional
fortification balanced against additional runtime cost (checking non-constant
bounds).
* The audit libraries will avoid unnecessary slowdown if it is not required
PLT tracking (by not implementing the la_pltenter or la_pltexit callbacks).
Deprecated and removed features, and other changes affecting compatibility:
* On x86-64, the LD_PREFER_MAP_32BIT_EXEC environment variable support
has been removed since the first PT_LOAD segment is no longer executable
due to defaulting to -z separate-code.
* The r_version update in the debugger interface makes the glibc binary
incompatible with GDB binaries built without the following commits:
c0154a4a21a gdb: Don't assume r_ldsomap when r_version > 1 on Linux
4eb629d50d4 gdbserver: Check r_version < 1 for Linux debugger interface
when audit modules or dlmopen are used.
* Intel MPX support (lazy PLT, ld.so profile, and LD_AUDIT) has been removed.
* The --enable-static-pie option is no longer available. The glibc build
configuration script now automatically detects static-pie support in the
toolchain and architecture and enables it if available.
* The catchsegv script and associated libSegFault.so shared object have
been removed. There are widely-deployed out-of-process alternatives for
catching coredumps and backtraces.
* Support for prelink will be removed in the next release; this includes
removal of the LD_TRACE_PRELINKING, and LD_USE_LOAD_BIAS, environment
variables and their functionality in the dynamic loader.
* The LD_TRACE_PRELINKING environment variable has been removed. Similar
functionality to obtain the program mapping address can be achieved by
using LD_TRACE_LOADED_OBJECTS to value of 2.
* The LD_USE_LOAD_BIAS has been removed. The variable was mainly used to
support prelink PIE binaries.
Changes to build and runtime requirements:
* The audit module interface version LAV_CURRENT is increased to enable
proper bind-now support. The loader now advertises via the la_symbind
flags that PLT trace is not possible. New audit modules require the
new dynamic loader supporting the latest LAV_CURRENT version. Old audit
modules are still loaded for all targets except aarch64.
* The audit interface on aarch64 is extended to support both the indirect
result location register (x8) and NEON Q register. Old audit modules are
rejected by the loader. Audit modules must be rebuilt to use the newer
structure sizes and the latest module interface version for LAV_CURRENT.
