commit 6a1cf708dd5681b517744d6d4fac02e4e4a0aa2e
Author: Aurelien Jarno <aurelien@aurel32.net>
Date: Wed Mar 11 21:03:50 2015 -0400
Fix ldconfig segmentation fault with corrupted cache (Bug 18093).
ldconfig is using an aux-cache to speed up the ld.so.cache update. It
is read by mmaping the file to a structure which contains data offsets
used as pointers. As they are not checked, it is not hard to get
ldconfig to segfault with a corrupted file. This happens for instance if
the file is truncated, which is common following a filesystem check
following a system crash.
This can be reproduced for example by truncating the file to roughly
half of it's size.
There is already some code in elf/cache.c (load_aux_cache) to check
for a corrupted aux cache, but it happens to be broken and not enough.
The test (aux_cache->nlibs >= aux_cache_size) compares the number of
libs entry with the cache size. It's a non sense, as it basically
assumes that each library entry is a 1 byte... Instead this commit
computes the theoretical cache size using the headers and compares it
to the real size.

The GNU C Library
=================
The GNU C Library version 2.22 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 2.22 release may be downloaded from:
http://ftpmirror.gnu.org/libc/

* Cache information can be queried via sysconf() function on s390 e.g. with
_SC_LEVEL1_ICACHE_SIZE as argument.
* A buffer overflow in gethostbyname_r and related functions performing DNS
requests has been fixed. If the NSS functions were called with a
misaligned buffer, the buffer length change due to pointer alignment was
not taken into account. This could result in application crashes or,
potentially arbitrary code execution, using crafted, but syntactically
valid DNS responses. (CVE-2015-1781)
* The time zone file parser has been made more robust against crafted time
zone files, avoiding heap buffer overflows related to the processing of
the tzh_ttisstdcnt and tzh_ttisgmtcnt fields, and a stack overflow due to
large time zone data files. Overly long time zone specifiers in the TZ
variable no longer result in stack overflows and crashes.
* A powerpc and powerpc64 optimization for TLS, similar to TLS descriptors
for LD and GD on x86 and x86-64, has been implemented. You will need
binutils-2.24 or later to enable this optimization.
* Character encoding and ctype tables were updated to Unicode 7.0.0, using
new generator scripts contributed by Pravin Satpute and Mike FABIAN (Red
Hat). These updates cause user visible changes, such as the fix for bug
17998.
* CVE-2014-8121 The NSS backends shared internal state between the getXXent
and getXXbyYY NSS calls for the same database, causing a denial-of-service
condition in some applications.
* Added vector math library named libmvec with the following vectorized x86_64
implementations: cos, cosf, sin, sinf, sincos, sincosf, log, logf, exp, expf,
pow, powf.
The library can be disabled with --disable-mathvec. Use of the functions is
enabled with -fopenmp -ffast-math starting from -O1 for GCC version >= 4.9.0.
Shared library libmvec.so is linked in as needed when using -lm (no need to
specify -lmvec explicitly for not static builds).
Visit <https://sourceware.org/glibc/wiki/libmvec> for detailed information.
* A new fmemopen implementation has been added with the goal of POSIX
compliance. The new implementation fixes the following long-standing
issues: BZ#6544, BZ#11216, BZ#12836, BZ#13151, BZ#13152, and BZ#14292. The
old implementation is still present for use be by existing binaries.
* The 32-bit sparc sigaction ABI was inadvertently broken in the 2.20 and 2.21
releases. It has been fixed to match 2.19 and older, but binaries built
against 2.20 and 2.21 might need to be recompiled. See BZ#18694.
* Port to Native Client running on ARMv7-A (--host=arm-nacl).

The GNU C Library
=================
The GNU C Library version 2.29 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 2.29 release may be downloaded from:

NEWS for version 2.29
====================
* The getcpu wrapper function has been added, which returns the currently
used CPU and NUMA node. This function is Linux-specific.
* A new convenience target has been added for distribution maintainers
to build and install all locales as directories with files. The new
target is run by issuing the following command in your build tree:
'make localedata/install-locale-files', with an optional DESTDIR
to set the install root if you wish to install into a non-default
configured location.
* Optimized generic exp, exp2, log, log2, pow, sinf, cosf, sincosf and tanf.
* The reallocarray function is now declared under _DEFAULT_SOURCE, not just
for _GNU_SOURCE, to match BSD environments.
* For powercp64le ABI, Transactional Lock Elision is now enabled iff kernel
indicates that it will abort the transaction prior to entering the kernel
(PPC_FEATURE2_HTM_NOSC on hwcap2). On older kernels the transaction is
suspended, and this caused some undefined side-effects issues by aborting
transactions manually. Glibc avoided it by abort transactions manually on
each syscall, but it lead to performance issues on newer kernels where the
HTM state is saved and restore lazily (the state being saved even when the
process actually does not use HTM).
* The functions posix_spawn_file_actions_addchdir_np and
posix_spawn_file_actions_addfchdir_np have been added, enabling
posix_spawn and posix_spawnp to run the new process in a different
directory. These functions are GNU extensions. The function
posix_spawn_file_actions_addchdir_np is similar to the Solaris function
of the same name.
* The popen and system do not run atfork handlers anymore (BZ#17490).
Although it is a possible POSIX violation, the POSIX rationale in
pthread_atfork documentation regarding atfork handlers is to handle
inconsistent mutex state after a fork call in a multi-threaded process.
In both popen and system there is no direct access to user-defined mutexes.
* Support for the C-SKY ABIV2 running on Linux has been added. This port
requires at least binutils-2.32, gcc-9.0, and linux-4.20. Two ABIs are
supported:
- C-SKY ABIV2 soft-float little-endian
- C-SKY ABIV2 hard-float little-endian
* strftime's default formatting of a locale's alternative year (%Ey)
has been changed to zero-pad the year to a minimum of two digits,
like "%y". This improves the display of Japanese era years during
the first nine years of a new era, and is expected to be harmless
for all other locales (only Japanese locales regularly have
alternative year numbers less than 10). Zero-padding can be
overridden with the '_' or '-' flags (which are GNU extensions).
* As a GNU extension, the '_' and '-' flags can now be applied to
"%EY" to control how the year number is formatted; they have the
same effect that they would on "%Ey".
Deprecated and removed features, and other changes affecting compatibility:
* The glibc.tune tunable namespace has been renamed to glibc.cpu and the
tunable glibc.tune.cpu has been renamed to glibc.cpu.name.
* The type of the pr_uid and pr_gid members of struct elf_prpsinfo, defined
in <sys/procfs.h>, has been corrected to match the type actually used by
the Linux kernel. This affects the size and layout of that structure on
MicroBlaze, MIPS (n64 ABI only), Nios II and RISC-V.
* For the MIPS n32 ABI, the type of the pr_sigpend and pr_sighold members of
struct elf_prstatus, and the pr_flag member of struct elf_prpsinfo,
defined in <sys/procfs.h>, has been corrected to match the type actually
used by the Linux kernel. This affects the size and layout of those
structures.
* An archaic GNU extension to scanf, under which '%as', '%aS', and '%a[...]'
meant to scan a string and allocate space for it with malloc, is now
restricted to programs compiled in C89 or C++98 mode with _GNU_SOURCE
defined. This extension conflicts with C99's use of '%a' to scan a
hexadecimal floating-point number, which is now available to programs
compiled as C99 or C++11 or higher, regardless of _GNU_SOURCE.
POSIX.1-2008 includes the feature of allocating a buffer for string input
with malloc, using the modifier letter 'm' instead. Programs using
'%as', '%aS', or '%a[...]' with the old GNU meaning should change to
'%ms', '%mS', or '%m[...]' respectively. Programs that wish to use the
C99 '%a' no longer need to avoid _GNU_SOURCE.
GCC's -Wformat warnings can detect most uses of this extension, as long
as all functions that call vscanf, vfscanf, or vsscanf are annotated with
__attribute__ ((format (scanf, ...))).
Changes to build and runtime requirements:
* Python 3.4 or later is required to build the GNU C Library.
* On most architectures, GCC 5 or later is required to build the GNU C
Library. (On powerpc64le, GCC 6.2 or later is still required, as before.)
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library.
Security related changes:
CVE-2018-19591: A file descriptor leak in if_nametoindex can lead to a
denial of service due to resource exhaustion when processing getaddrinfo
calls with crafted host names. Reported by Guido Vranken.
CVE-2019-6488: On x32, the size_t parameter may be passed in the lower
32 bits of a 64-bit register with with non-zero upper 32 bit. When it
happened, accessing the 32-bit size_t value as the full 64-bit register
in the assembly string/memory functions would cause a buffer overflow.
Reported by H.J. Lu.
CVE-2016-10739: The getaddrinfo function could successfully parse IPv4
addresses with arbitrary trailing characters, potentially leading to data
or command injection issues in applications.
