Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch increases the malloc alignment to 16 for i386.
[BZ #21120]
* sysdeps/generic/malloc-alignment.h: New file.
* sysdeps/i386/malloc-alignment.h: Likewise.
* sysdeps/generic/malloc-machine.h: Include <malloc-alignment.h>.

Get rid of duplicate const declaration specifier warning in tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the
buffer (which is dubious usage, but valid at runtime if in fact there
isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.
Tested compilation for aarch64 (GCC mainline) with
build-many-glibcs.py; did execution testing for x86_64 (GCC 5).
* string/tester.c (test_strncat): Disable -Wstringop-overflow=

Fix testsuite build for GCC 7 -Wformat-truncation.
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]
* nis/nss_nisplus/nisplus-alias.c (_nss_nisplus_getaliasbyname_r):
Compare name == NULL, not name != NULL.

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:

Fix string/tester.c for GCC 7 -Wstringop-overflow=.
GCC 7 has a -Wstringop-overflow= warning that includes warning for
strncat with a size specified that is larger than the size of the

isn't an overflow with the particular buffer contents present).
string/tester.c tests such cases; this patch arranges for this warning
to be ignored around relevant strncat calls.

Fix nss_nisplus build with mainline GCC (bug 20978).
glibc build with current mainline GCC fails because
nis/nss_nisplus/nisplus-alias.c contains code
if (name != NULL)
{
*errnop = EINVAL;
return NSS_STATUS_UNAVAIL;
}
char buf[strlen (name) + 9 + tablename_len];
producing an error about strlen being called on a pointer that is
always NULL (and a subsequent use of that pointer with a %s format in
snprintf).
As Andreas noted, the bogus conditional comes from a 1997 change:
- if (name == NULL || strlen(name) > 8)
- return NSS_STATUS_NOTFOUND;
- else
+ if (name != NULL || strlen(name) <= 8)
So the intention is clearly to return an error for NULL name.
This patch duly inverts the sense of the conditional. It fixes the
build with GCC mainline, and passes usual glibc testsuite testing for
x86_64. However, I have not tried any actual substantive nisplus
testing, do not have an environment for such testing, and do not know
whether it is possible that strlen (name) or tablename_len might be
large so that the VLA for buf is actually a security issue. However,
if it is a security issue, there are plenty of other similar instances
in the nisplus code (that haven't been hidden by a bogus comparison
with NULL) - and nis_table.c:__create_ib_request uses strdupa on the
string passed to nis_list, so a local fix in the caller wouldn't
suffice anyway (see bug 20987). (Calls to strdupa and other such
macros that use alloca must be considered equally questionable
regarding stack overflow issues as direct calls to alloca and VLA
declarations.)
[BZ #20978]

Fix rpcgen buffer overrun (bug 20790).
Building with GCC 7 produces an error building rpcgen:
rpc_parse.c: In function 'get_prog_declaration':
rpc_parse.c:543:25: error: may write a terminating nul past the end of the destination [-Werror=format-length=]
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
~~~~^
rpc_parse.c:543:5: note: format output between 5 and 14 bytes into a destination of size 10
sprintf (name, "%s%d", ARGNAME, num); /* default name of argument */
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
That buffer overrun is for the case where the .x file declares a
program with a million arguments. The strcpy two lines above can
generate a buffer overrun much more simply for a long argument name.
The limit on length of line read by rpcgen (MAXLINESIZE == 1024)
provides a bound on the buffer size needed, so this patch just changes
the buffer size to MAXLINESIZE to avoid both possible buffer
overruns. A testcase is added that rpcgen does not crash with a
500-character argument name, where it previously crashed.
It would not at all surprise me if there are many other ways of
crashing rpcgen with either valid or invalid input; fuzz testing would
likely find various such bugs, though I don't think they are that
important to fix (rpcgen is not that likely to be used with untrusted
.x files as input). (As well as fuzz-findable bugs there are probably
also issues when various int variables get overflowed on very large
input.) The test infrastructure for rpcgen-not-crashing tests would
need extending if tests are to be added for cases where rpcgen should
produce an error, as opposed to cases where it should succeed.
Tested for x86_64 and x86.
[BZ #20790]
* sunrpc/rpc_parse.c (get_prog_declaration): Increase buffer size
to MAXLINESIZE.
* sunrpc/bug20790.x: New file.
* sunrpc/Makefile [$(run-built-tests) = yes] (rpcgen-tests): New
variable.
[$(run-built-tests) = yes] (tests-special): Add $(rpcgen-tests).
[$(run-built-tests) = yes] ($(rpcgen-tests)): New rule.

Make copy of <bits/std_abs.h> from GCC 7 [BZ #21573]
<bits/std_abs.h> from GCC 7 will include /usr/include/stdlib.h from
"#include_next" (instead of stdlib/stdlib.h in the glibc source
directory), and this turns up as a make dependency. Also make a copy
of <bits/std_abs.h> to prevent it from including /usr/include/stdlib.h.
[BZ #21573]
* Makerules [$(c++-bits-std_abs-h) != ""] (before-compile): Add
$(common-objpfx)bits/std_abs.h.
[$(c++-bits-std_abs-h) != ""] ($(common-objpfx)bits/std_abs.h):
New target.
* config.make.in (c++-bits-std_abs-h): New.
* configure.ac (find_cxx_header): Use "\,$1," with sed.
(CXX_BITS_STD_ABS_H): New.
(AC_SUBST(CXX_BITS_STD_ABS_H)): Likewise.
* configure: Regenerated.

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).
