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.
