glibc maintains a binary tree of environment strings it malloc()ed
itself. However, it's possible for it to malloc() a string, then find
that an identical string is already in the tree. In this case, the
memory is leaked and is not freed if the application later calls
__libc_freeres(). Fix this by freeing 'new_value' when it's unneeded.
Test case:
#include <stdlib.h>
#include <string.h>
int main()
{
char *p = calloc(100000, 1);
memset(p, 'A', 99999);
setenv("TESTVAR", p, 1);
setenv("TESTVAR", p, 1);
free(p);
}
Leak that was reported by valgrind:
100,008 bytes in 1 blocks are definitely lost in loss record 1 of 1

Due to tile missing a bunch of FP exception and rounding
support, the tests generate warnings. These changes fix the
warnings by just not compiling some unused functions, and
adding some attribute ((unused)) tags.

This test used to define a 'struct entry' that conflicts with the
definition in search.h included in test-skeleton. The struct is
now renamed 'item'.

Replace with !IS_IN (libc). This completes the transition from
the IS_IN/NOT_IN macros to the IN_MODULE macro set.

The current scheme to identify which module a translation unit is
built in depends on defining multiple macros IS_IN_* and also defining
NOT_IN_libc if we're building a non-libc module. In addition, there
is an IN_LIB macro that does effectively the same thing, but for
different modules (notably the systemtap probes). This macro scheme
unifies both ideas to use just one macro IN_MODULE and assign it a
value depending on the module it is being built into. If the module
is not defined, it defaults to MODULE_libc.
Patches that follow will replace uses of IS_IN_* variables with the
IS_IN() macro. libc-symbols.h has been converted already to give an
example of how such a transition will look.
Verified that there are no relevant binary changes. One source change
that will crop up repeatedly is that of nscd_stat, since it uses the
build timestamp as a constant in its logic.
* Makeconfig (in-module): Get value of libof set for the
translation unit.
(CPPFLAGS): Use $(in-module).
* Makerules: Don't suffix routine names for nonlib.
* include/libc-modules.h: New file.

This patch fixes those warnings by using a prototype definition for

For 32-bit platforms, strtoll and strtoull are strong symbols in libc,
but they are not in ISO C90, and are brought in by references to
__strtoll_internal / __strtoull_internal from scanf. (For 64-bit
platforms, they are properly weak.) This patch makes them weak for
32-bit (it has a side-effect of making other symbols weak that don't
need to be weak, such as strtol, but that's harmless).
Tested for x86 (testsuite, and that the disassembly of installed
shared libraries is unchanged by the patch). This fixes all 120
unXFAILed FAILs of the new linknamespace tests seen for x86 (in fact,
there are now seven XPASSes of those tests for x86
XPASS: conform/POSIX2008/fcntl.h/linknamespace
XPASS: conform/UNIX98/libgen.h/linknamespace
XPASS: conform/XOPEN2K/fcntl.h/linknamespace
XPASS: conform/XOPEN2K/libgen.h/linknamespace
XPASS: conform/XOPEN2K8/fcntl.h/linknamespace
XPASS: conform/XOPEN2K8/libgen.h/linknamespace
XPASS: conform/XPG4/libgen.h/linknamespace
so suggesting that the failures seen for those on x86_64 are in some
way architecture-specific or 64-bit-specific).

qsort_r is defined in the same file as qsort, but is not an ISO C
function, so should be a weak alias for __qsort_r. The uses in
getaddrinfo should also call __qsort_r, since getaddrinfo is a POSIX
function and qsort_r isn't. This patch implements this. Because nscd
uses the getaddrinfo sources outside libc, as do the tst-rfc3484
tests, a #define of __qsort_r to qsort_r is added there alongside the
similar defines for other libc-internal symbols used in getaddrinfo.
Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

This patch modifies several test cases to use test-skeleton.c.
It was generated by a bash script written for this purpose and
thus excludes several other tests which I deemed worth a visual
inspection before making the change.
I intend to follow up with individual patches to the tests
skipped by the script.
The script itself resides at http://git.io/WODAmg and should
reproduce this very patch when run against master.

This patch removes use of the obsolete INTDEF/INTUSE mechanism for
__cxa_atexit, replacing it with libc_hidden_def/libc_hidden_proto.
Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.
[BZ #14132]
* stdlib/cxa_atexit.c (__cxa_atexit): Use libc_hidden_def instead
of INTDEF.
* include/stdlib.h (__cxa_atexit_internal): Remove declaration.

[!NOT_IN_libc] (__cxa_atexit): Remove macro definition.

Building this test on ARM fails because the prototypes for the long
double variants of the math functions are unavailable.
Add an additional include guard to math.h that enables long double math
function declarations if _LIBC_TEST is defined and define _LIBC_TEST in
stdlib/tst-strtod-round.c.
ChangeLog:
2014-09-30 Will Newton <will.newton@linaro.org>
* math/math.h: Define long double math functions if
_LIBC_TEST is defined.
* stdlib/tst-strtod-round.c: Define _LIBC_TEST.

GCC 4.4, the minimum compiler version, supports this option. Unlike
other warnings, -Wimplicit-function-declaration warnings should be
independent of compiler versions, so this change should not cause
compiler-specific build failures.

This test case is very, especially on targets using soft-float or QEMU
(where soft-float is used internally), and appears to be the only such
outlier. Therefore rather than requiring to have TIMEOUTFACTOR set
large enough globally, bump up the local scaling factor instead.
* stdlib/tst-strtod-overflow.c (TIMEOUT): Bump up to 30.

This fixes an off-by-one argc interpretation error (argv[0] is included
in the count) in stdlib/tst-qsort2.c causing a segfault if the program
is called with one command-line argument only (argv[2] is NULL in that
case).

consistent environment.
One wart in the original support for test wrappers for cross testing,
as noted in
<https://sourceware.org/ml/libc-alpha/2012-10/msg00722.html>, is the
requirement for test wrappers to pass a poorly-defined set of
environment variables from the build system to the system running the
glibc under test. Although some variables are passed explicitly via
$(test-wrapper-env), including LD_* variables that simply can't be
passed implicitly because of the side effects they'd have on the build
system's dynamic linker, others are passed implicitly, including
variables such as GCONV_PATH and LOCPATH that could potentially affect
the build system's libc (so effectively relying on any such effects
not breaking the wrappers). In addition, the code in
cross-test-ssh.sh for preserving environment variables is fragile (it
depends on how bash formats a list of exported variables, and could
well break for multi-line variable definitions where the contents
contain things looking like other variable definitions).
This patch moves to explicitly passing environment variables via
$(test-wrapper-env). Makefile variables that previously used
$(test-wrapper) are split up into -before-env and -after-env parts
that can be passed separately to the various .sh files used in
testing, so those files can then insert environment settings between
the two parts.
The common default environment settings in make-test-out are made into
a separate makefile variable that can also be passed to scripts,
rather than many scripts duplicating those settings (for testing an
installed glibc, it is desirable to have the GCONV_PATH setting on
just one place, so just that one place needs to support it pointing to
an installed sysroot instead of the build tree). The default settings
are included in the variables such as $(test-program-prefix), so that
if tests do not need any non-default settings they can continue to use
single variables rather than the split-up variables.
Although this patch cleans up LC_ALL=C settings (that being part of
the common defaults), various LANG=C and LANGUAGE=C settings remain.
Those are generally unnecessary and I propose a subsequent cleanup to
remove them. LC_ALL takes precedence over LANG, and while LANGUAGE
takes precedence over LC_ALL, it only does so for settings other than
LC_ALL=C. So LC_ALL=C on its own is sufficient to ensure the C
locale, and anything that gets LC_ALL=C does not need the other
settings.
While preparing this patch I noticed some tests with .sh files that
appeared to do nothing beyond what the generic makefile support for
tests can do (localedata/tst-wctype.sh - the makefiles support -ENV
variables and .input files - and localedata/tst-mbswcs.sh - just runs
five tests that could be run individually from the makefile). So I
propose another subsequent cleanup to move those to using the generic
support instead of special .sh files.
Tested x86_64 (native) and powerpc32 (cross).
