5ad589d63b support: Add support_open_dev_null_range
It returns a range of file descriptor referring to the '/dev/null'
pathname.  The function takes care of restarting the open range
if a file descriptor is found within the specified range and
also increases RLIMIT_NOFILE if required.

Checked on x86_64-linux-gnu.

70d08ba204 tests: use xmalloc to allocate implementation array
The benchmark and tests must fail in case of allocation failure in the
implementation array.  Also annotate the x* allocators in support.h so
that the compiler has more information about them.

ae8c243d24 support: Add support_stack_alloc
The code to allocate a stack from xsigstack is refactored so it can
be more generic.  The new support_stack_alloc() also set PROT_EXEC
if DEFAULT_STACK_PERMS has PF_X.  This is required on some
 architectures (hppa for instance) and trying to access the rtld
global from testsuite will require more intrusive refactoring
in the ldsodefs.h header.

Checked on x86_64-linux-gnu and i686-linux-gnu.  I also ran
tst-xsigstack on both hppa and ia64.

It is a simple wrapper over timer_create, timer_settime, and

1966f47a1e S390: Don't test nanoseconds in io/tst-stat.c
Both new tests io/tst-stat and io/tst-stat-lfs (_FILE_OFFSET_BITS=64)
are comparing the nanosecond fields with the statx result.  Unfortunately
on s390(31bit) those fields are always zero if old KABI with non-LFS
support is used.  With _FILE_OFFSET_BITS=64 stat is using statx internally.

As suggested by Adhemerval this patch disables the nanosecond check for
s390(31bit).

b2970919ba io: Return UNSUPPORTED if filesystem do not support 64 bit timestamps
Some Linux filesystems might not fully support 64 bit timestamps [1],
which make some Linux specific tests to fail when they check for the
functionality.

This patch adds a new libsupport function, support_path_support_time64,
that returns whether the target file supports or not 64 bit timestamps.
The support is checked by issuing a utimensat and verifying both the
last access and last modification time against a statx call.

The tests that might fail are also adjusted to check the file support
as well:

I used these shell commands:

and then ignored the output, which consisted lines saying "FOO: warning:

I then removed trailing white space from benchtests/bench-pthread-locks.c

diagnostic from Savannah:

92954ffa5a localedef: Add verbose messages for failure paths.
During testing of localedef running in a minimal container
there were several error cases which were hard to diagnose
since they appeared as strerror (errno) values printed by the
higher level functions.  This change adds three new verbose
messages for potential failure paths.  The new messages give
the user the opportunity to use -v and display additional
information about why localedef might be failing.  I found
these messages useful myself while writing a localedef
container test for --no-hard-links.

Since the changes cleanup the code that handle codeset
normalization we add tst-localedef-path-norm which contains
many sub-tests to verify the correct expected normalization of
codeset strings both when installing to default paths (the
only time normalization is enabled) and installing to absolute
paths.  During the refactoring I created at least one
buffer-overflow which valgrind caught, but these tests did not
catch because the exec in the container had a very clean heap
with zero-initialized memory. However, between valgrind and
the tests the results are clean.

The new tst-localedef-path-norm passes without regression on
x86_64.

bc79db3fd4 Fix alignment of TLS variables for tls variant TLS_TCB_AT_TP [BZ #23403]
The alignment of TLS variables is wrong if accessed from within a thread
for architectures with tls variant TLS_TCB_AT_TP.
For the main thread the static tls data is properly aligned.
For other threads the alignment depends on the alignment of the thread
pointer as the static tls data is located relative to this pointer.

This patch adds this alignment for TLS_TCB_AT_TP variants in the same way
as it is already done for TLS_DTV_AT_TP. The thread pointer is also already
properly aligned if the user provides its own stack for the new thread.

This patch extends the testcase nptl/tst-tls1.c in order to check the
alignment of the tls variables and it adds a pthread_create invocation
with a user provided stack.
The test itself is migrated from test-skeleton.c to test-driver.c
and the missing support functions xpthread_attr_setstack and xposix_memalign
are added.

ChangeLog:

	[BZ #23403]
	* nptl/allocatestack.c (allocate_stack): Align pointer pd for
	TLS_TCB_AT_TP tls variant.
	* nptl/tst-tls1.c: Migrate to support/test-driver.c.

e7624d708d Adjust name of ld.so in test-container.c.
The test-container.c file assumes that ld.so is always named
something like /elf/ld-linux-*.
But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390.
There are other architectures like power or mips with similar names.

This patch introduces the new global variable support_objdir_elf_ldso
which contains the absolute path to the runtime linker used by the
testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2.
The check in test-container.c is now comparing against this path.
Without this patch, test-container.c is searching invalid files / directories
and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script.
Then the test tst-nss-test3 fails!

c23de0aacb support: Introduce new subdirectory for test infrastructure
The new test driver in <support/test-driver.c> has feature parity with
the old one.  The main difference is that its hooking mechanism is
based on functions and function pointers instead of macros.  This
commit also implements a new environment variable, TEST_COREDUMPS,
which disables the code which disables coredumps (that is, it enables
them if the invocation environment has not disabled them).

<test-skeleton.c> defines wrapper functions so that it is possible to
use existing macros with the new-style hook functionality.

This commit changes only a few test cases to the new test driver, to
make sure that it works as expected.
