46c1ffa4d5 Declare pthread_atfork in unistd.h for UNIX98 (bug 20044). 
For UNIX98 (only), unistd.h should declare pthread_atfork, but that
declaration is missing.  This patch adds it.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

9e6e128d14 conformtest: Remove some bogus sys/types.h expectations for XPG3 and XPG4. 
The conformtest tests for sys/types.h for XPG3 and XPG4 fail because
of missing blksize_t.  This is a bug in the expectations; that type is
not part of those standards.  This patch stops the tests from
expecting it, and some other types that also are not part of XPG3 and
XPG4.

Tested for x86_64 and x86.

2faba597ec Fix sys/time.h timespec namespace (bug 20041). 
For UNIX98 and older standards, sys/time.h should not define struct
timespec, but does so via the inclusion of sys/select.h (which is a
new header in the 2001 edition of POSIX, and defines struct timespec
because of the declaration of pselect, a new function in the 2001
edition of POSIX).  In turn, this affects some other headers that
themselves include sys/time.h.

This patch fixes this by conditioning the __need_timespec definition
in sys/select.h on __USE_XOPEN2K, the same condition used there for
the declaration of pselect (this has no effect on direct uses of
sys/select.h with feature test macros for any standard that includes
that header, since such standards result in __USE_XOPEN2K being
defined).

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

35281b18b8 Fix fcntl.h timespec namespace (bug 20023). 
fcntl.h defines struct timespec if __USE_XOPEN || __USE_XOPEN2K8.  But
(a) the subsequent bits/stat.h include only needs it if __USE_XOPEN2K8
and (b) older standards did not allow struct timespec here.  (It's
allowed for newer standards by virtue of the permission to include
symbols from sys/stat.h.  But sys/stat.h is only required to provide
struct timespec from the 2008 edition of POSIX onwards, and permitted
by the 2004 TC to the 2001 edition in anticipation of the addition of
nanosecond timestamp support to struct stat in the 2008 edition.)

This patch limits the timespec definition to the __USE_XOPEN2K8 case,
that being the only case where it is actually needed for the
<bits/stat.h> include.

Tested for x86_64 and x86 (testsuite, and that installed stripped

a7657f3012 Fix stdio.h namespace for pre-threads POSIX (bug 20014). 
stdio.h declares flockfile, ftrylockfile, funlockfile, getc_unlocked,
getchar_unlocked, putc_unlocked and putchar_unlocked if __USE_POSIX,
with comments "These are defined in POSIX.1:1996.".  But __USE_POSIX
is actually POSIX.1:1990, and these functions should not be declared
for 1990 / 1992 / 1993 POSIX, XPG3 or XPG4.  This patch fixes stdio.h
to use __USE_POSIX199506 instead for those conditionals, as that is
the correct conditional for the version of POSIX that introduced
threads, and with threads those functions.

10b8108aec Also define off_t in stdio.h for UNIX98. 
Similar to my previous fix for XOPEN2K
<https://sourceware.org/ml/libc-alpha/2016-04/msg00631.html>, now that
bugs in the conformtest expectations for stdio.h for UNIX98 have been
corrected, that case too fails because fseeko and ftello are now
correctly expected, but off_t is not defined.  As in that fix, it
seems appropriate to define off_t in stdio.h for this standard as
well, and this patch does so.

The conform/ test of stdio.h for UNIX98 fails with surious namespace
errors for functions that are correctly declared for that standard.
This patch fixes the expectations to expect those functions also for
UNIX98.  (This does not by itself fix the XFAIL of that test, and is
not based a full review of the header expectations so there could
still be other bugs in the expectations for this header for UNIX98.)

9f57e65c93 conformtest: Correct some signal.h expectations for XOPEN2K. 
The conformtest expectations for signal.h have various declarations
that are expected for POSIX (1996) and all later standards, except,
wrongly, for XOPEN2K.  This shows up as failures of tests for two
other headers, which are allowed to make visible symbols from
signal.h, because of an incorrect namespace failure for sigval
(required in signal.h in XOPEN2K, so should be allowed for those other
headers); signal.h tests for various standards fail anyway because of
other problems in the header.  This patch fixes the incorrect
expectations and removes the two XFAILs that this fixes.

bf07472615 Define off_t in stdio.h for XOPEN2K. 
The header conformance test for stdio.h for XOPEN2K fails because the
header does not define the off_t type, used in the expected
declarations for fseeko and ftello.

The absence of this type is not actually strictly a bug (hence no bug
report being filed in Bugzilla), since POSIX didn't require the type
to be declared in this header until the 2008 edition.  However, the
glibc convention in such cases - where the type falls under the
general *_t POSIX reservation, and so it's OK to define it for all
POSIX versions - is to make the headers self-contained in this regard
even for the older POSIX versions not requiring the type to be defined
despite including other declarations depending on the type.  Thus,
this patch adjusts the condition in the header and removes the XFAIL
(rather than adapting the expectation to work when the functions are
declared using __off_t without off_t being defined).

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

12404bb04e Fix stdio.h cuserid namespace (bug 19989). 
stdio.h declares cuserid if __USE_XOPEN.  But this was removed in the
2001 edition of POSIX.

The #endif comment "Use X/Open, but not issue 6." reflects the correct
logic, but does not correspond to the #ifdef.  The use of a correct
libc-hacker.  The online archives for libc-hacker in August 2000 are
broken, but the messages can be found in the qmail archives in
/sourceware1/qmail/lists-sourceware/libc-hacker/archive/26 if you have
shell access to sourceware.

The issue showed up in August 2000 because of a warning about a
non-prototype definition in sysdeps/posix/cuserid.c when there was no
previous prototype declaration.  Since we've now eliminated
non-prototype function definitions, that issue does not apply.  The
other points from that discussion were about whether it should be
included in _GNU_SOURCE; whether _GNU_SOURCE should include
"everything"; whether deprecated interfaces such as this should be
excluded from it; and whether, even given exclusion of deprecated
interfaces, it should apply for deprecations in a version of POSIX
that at that time had not been released.

This patch follows the more conservative approach to a fix of keeping
the interface in _GNU_SOURCE.  That matches how L_cuserid is handled.
I think there is a strong case for eliminating this interface from
_GNU_SOURCE (but this may not automatically be the case for every
interface removed in newer POSIX versions), but then L_cuserid should
also be removed from _GNU_SOURCE (in stdio-common/stdio_lim.h.in) at
the same time.

libraries are unchanged by the patch).

eb64b6d457 Fix limits.h NL_NMAX namespace (bug 19929). 
bits/xopen_lim.h (included by limits.h if __USE_XOPEN) defines
NL_NMAX, but this constant was removed in the 2008 edition of POSIX so
should not be defined in that case.  This patch duly disables that
define for __USE_XOPEN2K8.  It remains enabled for __USE_GNU to avoid
affecting sysconf (_SC_NL_NMAX), the implementation of which uses
"#ifdef NL_NMAX".

defines XCASE if defined __USE_MISC || defined __USE_XOPEN.  This
macro was removed in the 2001 edition of POSIX, and is not otherwise
reserved, so should not be defined for 2001 and later versions of
POSIX.  This patch fixes the conditions accordingly (leaving the macro
defined for __USE_MISC, so still in the default namespace).

d709042a6e Fix lgamma setting signgam for ISO C (bug 15421). 
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the
signgam variable even when building for strict ISO C conformance
(-std=c99 / -std=c11), although the user may define such a variable
and it's only in the implementation namespace for POSIX with XSI
extensions enabled.

Following discussions starting at
<https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and
<https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems
that the safest approach for fixing this particular issue is for
signgam to become a weak alias for a newly exported symbol __signgam,
with the library functions only setting __signgam, at which point
static linker magic will preserve the alias for newly linked binaries
that refer to the library's signgam rather than defining their own,
while breaking the alias for programs that define their own signgam,
with new symbol versions for lgamma functions and with compat symbols
for existing binaries that set both signgam and __signgam.

This patch implements that approach for the fix.  signgam is made into
a weak alias.  The four symbols __signgam, lgamma, lgammaf, lgammal
get new symbol versions at version GLIBC_2.23, with the existing
versions of lgamma, lgammaf and lgammal becoming compat symbols.

When the compat versions are built, gamma, gammaf and gammal are
aliases for the compat versions (i.e. always set signgam); this is OK
as they are not ISO C functions, and avoids adding new symbol versions
for them unnecessarily.  When the compat versions are not built
(i.e. for static linking and for future glibc ports), gamma, gammaf
and gammal are aliases for the new versions that set __signgam.  The
ldbl-opt versions are updated accordingly.

The lgamma wrappers are adjusted so that the same source files,
included from different files with different definitions of
USE_AS_COMPAT, can build either the new versions or the compat
versions.  Similar changes are made to the ia64 versions (untested).

Tests are added that the lgamma functions do not interfere with a user
variable called signgam for ISO C, with various choices for the size
of that variable, whether it is initialized, and for static and
dynamic linking.  The conformtest whitelist entry is removed as well.

Tested for x86_64, x86, mips64 and powerpc, including looking at
objdump --dynamic-syms output to make sure the expected sets of
symbols were aliases.  Also spot-tested that a binary built with old
glibc works properly (i.e. gets signgam set) when run with new glibc.

de20571d40 Fix math.h, tgmath.h XSI POSIX namespace (gamma, isnan, scalb) (bug 18967). 
math.h incorrectly declares various functions for XSI POSIX 2001 and
2008 editions.  gamma was removed in the 2001 edition but is still
declared, along with gammaf and gammal which were never standard
functions.  isnan is still declared as a function, along with isnanf
and isnanl which were never standard functions, although in 2001 the
function was replaced by the type-generic macro.  scalbf and scalbl
are declared although never standard, and scalb was removed in the
2008 edition but is still declared.  The scalb type-generic macro in
tgmath.h shouldn't be present for any POSIX version, since POSIX never
had such a type-generic macro.

This patch disables all those declarations in the relevant cases (as a
minimal fix, it leaves them enabled for __USE_MISC).  For the matter
of declaring scalb but not scalbf or scalbl for the 2001 edition, a
new macro __MATH_DECLARING_DOUBLE is added, defined by math.h around
includes of bits/mathcalls.h, for bits/mathcalls.h to use to test
which type's functions are being declared.

3840aabcd5 conform/linknamespace: whitelist matherrf/matherrl 
glibc supports the deprecated matherr hook for math error reporting.  The
conform tests take this into consideration and whitelist this symbol when
running linknamespace tests.

The ia64 libm code has long provided two additional hooks in this space:
	matherrf (for floats)
	matherrl (for long doubles)

Which causes the conform tests to fail with chains that all look like:
	[initial] __atan2 ->
	[libm.a(e_atan2.o)] __libm_error_support ->
	[libm.a(libm_error.o)] matherrf

We can't (losslessly) redirect existing usage of these funcs to matherr
because the structure passed in is different -- matherr uses a struct with
doubles while matherrf/matherrl use floats and long doubles respectively.
Plus, this has been part of the exported ABI since glibc-2.2.3, so it
doesn't feel right to change it so late.

Until we get around to obsoleting matherr entirely, whitelist these two
additional ia64 symbols.

but not for XOPEN2K8 (wrongly).  This patch fixes the data to expect
it for XOPEN2K8 as well.

(As for all such fixes based on failures seen from the tests, there is
no guarantee that the data is fully correct for a particular standard

I hope eventually to review the others.)

5675961d15 conformtest: Support xfail markers on individual assertions. 
Various conformtest tests fail because of known issues, filed in
Bugzilla, that are hard to fix (requiring new features, kernel
cooperation or involving changing types in ways that may involve care
around padding when interfacing to the kernel).  Such an issue has the
effect of making the whole test for the (standard, header) pair fail,
so hiding any other issues with that header for that standard
(possibly regressions or architecture-specific issues).

This patch adds a mechanism for individual conformtest test
expectations to start with xfail-, meaning that a failure of that
particular assertion does not cause the whole test to fail at the
makefile level and so failure at the makefile level can be used to
detect other issues that are likely to be easier to fix.  This is
similar to the whitelisted symbols in the linknamespace tests, or the
marking of particular libm tests as allowing spurious or missing
exceptions, for example.  The bugs filed in Bugzilla should still be
fixed, and the xfail- markers removed at that point, but xfail-
renders the tests more useful until that happens.

Note that there is no way to add such a marker for the assertion that
a header uses only symbols in the namespace of symbols it's meant to
use.  I don't think there's any need for a way to xfail those
namespace tests other than xfailing the whole (standard, header) pair
at the makefile level, since they are generally straightforward to fix
(add appropriate conditionals on the problem definitions).

The xfails in this patch do not necessarily cover all cases of
hard-to-fix header bugs filed in Bugzilla that currently show up in
conformtest failures; there may be more yet to add for existing open
bugs.

45dcd79f6e Fix swscanf vswscanf namespace (bug 18542). 
swscanf (added in C90 Amendment 1, present in UNIX98) calls vswscanf
(added in C99, not in C90 Amendment 1 or UNIX98).  This patch fixes
this by using __vswscanf instead and making vswscanf into a weak
alias.

(I intend to add conform/ test support for C90 Amendment 1 - and
various other standard versions supported by glibc but not yet by
conform/ tests - at some point, once the results for currently tested
standards are cleaner.)

The sem_* functions bring in references to tdelete, tfind, tsearch and
twalk.  But the t* functions are XSI-shaded, while sem_* aren't.  This

using libc_hidden_* for the benefit of calls within libc.

syslog functions (in POSIX) bring in the strong symbol vsyslog (not in

alias to a weak alias.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).  (vsyslog becomes weak
in the static libraries, which is what's needed; the particular macro
sequence in use leaves it as strong in the shared libraries, hence
those libraries being completely unchanged, but it doesn't generally
matter whether symbols exported from the shared libraries are weak or

17c199ee92 Fix gethostbyaddr in6addr_any, in6addr_loopback namespace (bug 18532). 
gethostbyaddr brings in references to in6addr_any and thereby
in6addr_loopback, which aren't in all the standards containing
gethostbyaddr (gethostbyaddr is in XPG4 and UNIX98, in6addr_any and
in6addr_loopback are new in POSIX.1:2001).  This patch fixes this by
making those symbols into weak aliases (safe in this case, unlike for
most data symbols, because these data symbols are const).

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of

bf1435783d Fix linknamespace expectations for in6addr_any, in6addr_loopback. 
Some linknamespace test failures turned out to be because the
variables in6addr_any and in6addr_loopback weren't listed in the lists
of extra reserved symbols for the relevant standards (only functions
are handled automatically through -aux-info, data symbols need listing
manually in list-header-symbols.pl).  This patch duly adds those

because of references to those symbols being brought in for standards
that didn't reserve them: bug 18532, to be fixed separately).

netdb.h declares interfaces such as getaddrinfo if __USE_POSIX,
i.e. POSIX.1:1990 or later.  However, these interfaces were new in the
2001 edition of POSIX, although the header was in XPG4 and UNIX98, so
they should not be declared for XPG4 or UNIX98.  (This produces
spurious linknamespace test failures, although there are other
failures for this header as well for the same standards so this patch
doesn't remove any XFAILs.)  This patch corrects the condition, and
the conform/ test expectations which were similarly wrong.

b400fdefc7 Fix grp.h endgrent, getgrent namespace (bug 18528). 
grp.h declares endgrent and getgrent if __USE_XOPEN2K8 (i.e. 2008
edition of POSIX, non-XSI).  However, the 2013 Technical Corrigendum
corrected the grp.h specification to XSI-shade these functions as in
previous editions (see <http://austingroupbugs.net/view.php?id=24>),
so they should not be declared for non-XSI POSIX.  This patch corrects
the conditions - using __USE_MISC || __USE_XOPEN_EXTENDED to match
setgrent - and the conform/ test expectations for this header, thereby
fixing the conform tests for this header for XPG3 (where the
expectations were wrong) and the linknamespace tests for it for
POSIX2008 (where the header bug meant it was wrongly considered a
problem for endgrent to bring in a reference to setgrent).

9714012ca0 Fix aio_* pread namespace (bug 18519). 
aio_* bring in references to pread, which isn't in all the standards
containing aio_* (as a reference from one library to another, this is
a bug for dynamic as well as static linking).  This patch fixes this
by using __libc_pread instead, exporting that function from libc at
symbol version GLIBC_PRIVATE; the code, with conditionals that may
call either __pread64 or __libc_pread, becomes exactly analogous to
that elsewhere in the same file that may call either __pwrite64 or
__libc_pwrite.

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed shared libraries).  libc changes because of the PLT entry
for the newly exported __libc_pread; librt changes because of
assertion line numbers and PLT rearrangement; other stripped installed

9acacaa02f Fix h_errno namespace (bug 18520). 
The 2008 edition of POSIX removed h_errno, but some functions still
bring in references to the h_errno external symbol.  As this symbol is
not a part of the public ABI (only __h_errno_location is), this patch
fixes this by renaming the GLIBC_PRIVATE TLS symbol to __h_errno.

Tested for x86_64 and x86 (testsuite, and comparison of installed
shared libraries).  Disassembly of all shared libraries using h_errno
changes because of the renaming (and changes to associated TLS / GOT
offsets in some cases); disassembly of libpthread on x86_64 changes
more substantially because the enlargement of .dynsym affects
subsequent addresses.

007f2dd122 Fix psignal, psiginfo declaration conditions (bug 18483). 
signal.h declares psignal and psiginfo if __USE_XOPEN2K - that is, for
the 2001 edition of POSIX.  These functions were actually added in the
2008 edition (as indicated in the header comments).  This patch fixes
the header conditionals.  This fixes some linknamespace test failures
because psiginfo uses fmemopen, which is also new in the 2008 edition,
so before the header fix this appeared to the linknamespace tests as a
2001 function bringing in references to a 2008 function.  The problem
also appeared in conformtest header namespace test results (the
conformtest data has correct conditionals for when these functions
should be visible), but the affected headers still have other
namespace problems so this doesn't fix any of those XFAILs.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

f014e87eff Fix fnmatch strnlen namespace (bug 18470). 
fnmatch brings in references to strnlen, which isn't in all the
standards that contain fnmatch (not added until the 2008 edition of
POSIX), resulting in linknamespace test failures.  (This is contrary
to glibc conventions, rather than a standards conformance issue,
because of the str* reservation.)  This patch fixes this in the usual
way, using __strnlen instead of strnlen.

4e5f9259f3 Restore _POSIX2_C_VERSION definition (bug 438). 
My review of conformtest expectations for POSIX showed up that the
_POSIX2_C_VERSION macro, required by POSIX and XPG standards before
2001, was missing in unistd.h, having been removed on 2003-04-03
despite those standards still being supported.  This patch adds it
back.  As it's in the implementation namespace, there's no need for it
to be conditional, and other such macros aren't conditional in this
header either.

Tested for x86_64 and x86 (testsuite).  Note that this *does* change
the installed libraries, because it affects the sysconf support
(present all along) for _SC_2_C_VERSION.

cf06a4e357 Fix pathconf basename namespace (bug 18444). 
pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename.  But

When cleaning up conformtest expectations for POSIX for locale.h in

that locale.h had contents defined in POSIX.2:1993 as well as

8e65ea4dc0 Fix linknamespace test handling of architecture-specific st_other. 
For mips16, some of the linknamespace tests were failing because
[MIPS16] annotations in readelf output were wrongly interpreted as
falling in the symbol index field, meaning symbol index values were
wrongly interpreted as symbol names and such names as 1 and 2 then
resulted in namespace test failures.

This patch fixes this by removing the annotations for such
architecture-specific st_other bits before splitting the readelf
output into fields.  Tested for x86_64 and mips16.

1a2325c06c Fix posix_spawn getrlimit64 namespace (bug 17991). 
posix_spawn (a standard POSIX function) brings in a use of getrlimit64
(not a standard POSIX function).  This patch fixes this by using
__getrlimit64 and making getrlimit64 a weak alias.

This is more complicated than some such changes because of files that
define getrlimit64 in their own way using symbol versioning after
including the main sysdeps/unix/sysv/linux/getrlimit64.c with a
getrlimit macro defined.  There are various existing patterns for such
cases in glibc; the one I've used here is that a getrlimit64 macro
disables the weak_alias / libc_hidden_weak calls, leaving it to the
including file to define the getrlimit64 name in whatever way is
appropriate.

Tested for x86_64 and x86 that installed stripped shared libraries are
unchanged by this patch.

b8986484e4 Fix isblank / isascii / toascii namespace (bug 17635). 
Use of isblank brings in isascii and toascii, but isblank is a C99
function and the other two aren't; similarly, isascii and toascii are
UNIX98 functions and bring in isblank, which isn't.  (Not a
conformance issue because of the is* and to* reservation, but still
contrary to glibc practice.)  This patch fixes this by splitting
isblank out of ctype-extn.c to a separate ctype-c99.c.  isblank_l is
also moved to a separate file, ctype-c99_l.c (non-XSI POSIX.1-2008 has
isblank_l, but isascii / toascii are marked OB XSI).  (In principle
all these functions could go in separate files - that's optimal for
static linking - but they are also all very small, and splitting them
all out is not needed to fix the present bug.)

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch - the ordering in which new and
existing sources are listed in ctype/Makefile is arranged so functions
go in the same order so that this comparison works).

8ac5a76a99 Fix resolver inet_* namespace (bug 17722). 
Parts of the resolver brought in by pthreads (at least) use inet_*
functions that aren't in the 1995/6 edition of POSIX that introduced
pthreads (or in one case, use __inet_aton which is then defined in the
same file as non-weak inet_addr).  This patch fixes this by making the
affected functions into weak alias for __inet_* and using those names
in the problematic resolver code.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

380292ba8b Fix x86_64 memrchr namespace (bug 17719). 
On x86_64, memrchr (not a standard function) is defined as a strong
symbol, instead of a weak alias of __memrchr as on other
architectures.  This results in linknamespace test failures from the
use of __memrchr from dirname.  (Not a conformance issue because of
the mem* reservation, but contrary to glibc conventions.)  This patch
makes x86_64 follow other architectures by defining memrchr as a weak
alias.

9a44d530c4 Fix resolver if_* namespace (bug 17717). 
Resolver code, brought in by pthreads (at least), uses if_* interfaces

2cfbdb9a27 Fix strftime wcschr namespace (bug 17634). 
Use of strftime, a C90 function, ends up bringing in wcschr, which is
not a C90 function.  Although not a conformance bug (C90 reserves
wcs*), this is still contrary to glibc practice of avoiding relying on
those reservations; this patch arranges for the internal uses to use
__wcschr instead, with wcschr being a weak alias.  This is more
complicated than some such patches because of the various IFUNC
definitions of wcschr (which include code redefining libc_hidden_def
in a way that involves creating __GI_wcschr manually and so also needs
to create __GI___wcschr after the change of internal uses to use
__wcschr).

Tested for x86_64 and 32-bit x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).

c5c2b7c3fd Fix pthreads getrlimit, gettimeofday namespace (bug 17682). 
Some pthreads functions use getrlimit and gettimeofday, but these
functions are XSI, not base POSIX; this is a namespace issue for
dynamic linking as well as static linking.  This patch makes them use
__getrlimit and __gettimeofday instead - the former needed to be newly
exported from libc.so at GLIBC_PRIVATE (and so now needs
libc_hidden_proto / libc_hidden_def), the latter was already exported.

Some linknamespace tests were failing because of references to

and XOPEN2K; this patch adds it to the list of allowed data symbols
for those standards.  (h_errno was removed in the 2008 edition of
POSIX, so POSIX2008 and XOPEN2K8 references to it are genuine bugs;
fortunately it's not a public data symbol - __h_errno_location is
public, TLS h_errno is GLIBC_PRIVATE - so the symbol can simply be
renamed to __h_errno to fix those bugs without the ABI complications
normally associated with namespace issues for data symbols.)

7f994279e9 Fix getifaddrs, freeifaddrs namespace (bug 17668). 
Various objects in glibc bring in ifaddrs.o (via references to
__netlink_*) and thereby getifaddrs and freeifaddrs, which are not
part of any standard supported by glibc.  These should be weak aliases
of __getifaddrs and __freeifaddrs; this patch makes them so.

(The path by which these functions are brought in is Linux-specific,
but it seems less confusing to make all versions of these functions
weak aliases rather than only the Linux-specific versions that
definitely need it.)

84e5e75640 Fix fgets_unlocked namespace issues (bug 17664). 
Various POSIX functions bring in res_init.o, res_hconf.o or
mntent_r.o, which use fgets_unlocked, which is not a POSIX function.
This patch arranges for them to use __fgets_unlocked instead.  (The
IS_IN (libc) conditional in rec_hconf.c is needed because that file is
also used in nscd.)

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch except for an assertion line
number).  Note that most of the linknamespace tests that failed
because of fgets_unlocked from the resolver also fail because of other
symbols brought in by the resolver, so the number of XFAILs this
removes is limited.  Also note that fgets_unlocked failures for
unistd.h for XPG3/XPG4 showed up that actually unistd.h is declaring
too much for XPG3/XPG4 (bug 17665) - there is no actual need to make
getusershell.c use __fgets_unlocked (at least as regards formal
standards are concerned; maybe it should still change for
namespace-cleanness of _DEFAULT_SOURCE) because the functions there
aren't actually in any of the supported standards; the correct fix for
those failures will be to stop the *usershell* functions appearing in
unistd.h for XPG3/XPG4.

0e7e69baa8 Make linknamespace tests check only relevant libraries. 
This patch addresses one known caveat in the linknamespace tests: with
this patch they will now only look for definitions of symbols in
relevant libraries, meaning that librt and libpthread are not checked
for ISO C standards, XPG3 and XPG4.

In particular, this means that if __pthread_initialize_minimal is
somehow brought in for one of those standards, the definition from
libc-tls.o will be considered instead of that from libpthread, so
avoiding bringing in lots of other libpthread symbols.  This should
address some of the failures reported by Carlos in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00882.html>, where
__pointer_chk_guard_local brought in __pthread_initialize_minimal.

Tested for x86_64.  The removal of one XFAIL for XPG4 actually shows
up a header bug (shm_open should not be declared for XPG4 - the
namespace issue was for symbols brought in by shm_open, which is no
longer found at all now librt isn't searched; I've filed bug 17663 for
the header bug, though it would show up eventually anyway in the
course of review of conform/ data against XPG4).

This patch makes the installed signal.h declare __sigpause only when
necessary (when a macro definition of sigpause makes use of
__sigpause), rather than unconditionally.  This fixes false positives
in the linknamespace tests by making it visible to those tests that no
use of ISO C functionality will actually bring in the definition of
__sigpause and so bring in the other symbols defined in the same
object.  There is no bug filed in Bugzilla because this is fixing
false positives rather than any user-visible bug.

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by this patch).

	* signal/signal.h (__sigpause): Only declare if [__USE_XOPEN &&
	!__GNUC__].
	* include/signal.h (__sigpause): Move declaration above call to
	libc_hidden_proto.
	* conform/Makefile (test-xfail-ISO/signal.h/linknamespace): Remove
	variable.

24f4f8253f Add tests for namespace for static linking. 
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.

This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests).  The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option.  The following comment from
linknamespace.pl explains the caveats around this approach:

Here's an example of the output for ISO (C90) assert.h, from before my
recent fixes and whitelisting of cases that seem more complicated to
fix:

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards).  (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)

As noted in bug 16978, older POSIX versions include

in the specified contents of <tar.h>, with only the 2001 edition
introducing the notion of XSI-conditional definitions and conditioning
that definition.  Thus, this macro should be defined for
!__USE_XOPEN2K as well as for __USE_XOPEN, and this patch duly defines
it in that case.  Tested x86_64.

POLL_* and TRAP_* to be exposed in <signal.h> (and <sys/wait.h>), even
though those symbols are not in non-XSI POSIX before POSIX.1-2008 and
even in POSIX.1-2008 the TRAP_* symbols are XSI-only.  This patch
conditions the symbols appropriately in the various <bits/siginfo.h>
implementations (various <signal.h> and <sys/wait.h> conformtest
issues remain for standards other than POSIX (1995/6)).  Tested
x86_64.

bc61d27c61 Include all of <time.h> from <sched.h> for older standards (bug 16670). 
This patch fixes one of the header namespace issues shown up by
conformtest, <sched.h> failing to expose all symbols from <time.h> as
required by older standards.  The patch keeps the existing behavior if
__USE_XOPEN2K is defined (the default; POSIX.1-2001 was the version
that made it optional to expose these symbols), but ensures that all
the symbols from <time.h> are exposed if an older standard is
selected.  Tested x86_64.

54ee292da7 conformtest: split up running of tests from makefile. 
This patch changes the logic by which header conformance tests are run
so that the makefiles run the tests for each (standard, header) pair
separately rather than as a single test (there are 518 such pairs
being tested at present).

Since these tests are slow and previously couldn't be run in parallel,
this obviously speeds up the whole test run significantly when using
parallel testing.  There are other benefits.  These tests can now be
marked as expected to fail at the level of (standard, header) pairs,
meaning that regressions introduced by a header change are much more
likely to be spotted (of course, such a regression could be a bug in
the header or in the expectations, most of which have not been
properly checked against the relevant standards).

The patch introduces lists in conform/Makefile of the headers to test
for each standard, with a new (quick) test for each standard that the
list agrees with the set of headers for which there are in fact
nonempty expectations for that standard.  This means that each of the
518 pairs being tested is actually something meaningful to test rather
than a null test.  I also hope to use these lists of headers in
various standards in future tests for namespace violations where a
function in a standard is implemented to call a non-reserved name for
a function outside that standard.

Although there are a lot of tests now marked as expected to fail, I
expect most of those to be easy to fix (whether with fixes to the
expectations, the headers or both - if fixing a header bug, of course
file it in Bugzilla first); only a limited number are likely to
reflect actual missing features in glibc.

Tested x86_64 (GCC 4.7 branch).  It's quite possible some failures
vary from platform to platform, in which case either additional XFAILs
can be added here, or platform-specific header bugs (if applicable)
the failures show up can be fixed.  I made XFAILs unconditional for
tests that should only fail for GCC 4.6 and earlier; we could make the
GCC version available in the makefiles and condition these, but simply
moving the XFAILing to a finer granularity seems a clear improvement
on the previous state of the whole of conformtest being XFAILed.

a00f522af8 conformtest: clean up POSIX expectations for semaphore.h, signal.h, tar.h. 
Continuing the series of patches to clean up conformtest expectations
for "POSIX" (1995/6) based on review of the expectations against the
standard, this patch cleans up those for semaphore.h, signal.h and
tar.h (including various corrections for other standards for the
expectations affected by this patch).  Tested x86_64.

(Some of the failures for signal.h shown up by this patch correcting
expectations for that header are among the reasons for posix/annexc
being expected to fail.  The goal is for conformtest eventually to
replace posix/annexc and stdlib/isomac once it has all relevant
functionality, and for the loop over standards and headers in
conformtest to convert to separate makefile targets for each
combination, so they can be run in parallel and so that xfails can be
more specific than the present xfailing of the whole of conformtest.)

f214606a0e Enumerate tests with special rules in tests-special variable. 
This patch is a revised and updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html>.

In order to generate overall summaries of the results of all tests in
the glibc testsuite, we need to identify and concatenate the files
with the results of individual tests.

Tomas Dohnalek's patch used $(common-objpfx)*/*.test-result for this.
However, the normal glibc approach is explicit enumeration of the
expected set of files with a given property, rather than all files
matching some pattern like that.  Furthermore, we would like to be
able to mark tests as UNRESOLVED if the file with their results is for
some reason missing, and in future we would like to be able to mark
tests as UNSUPPORTED if they are disabled for a particular
configuration (rather than simply having them missing from the list of
tests as at present).  Such handling of tests that were not run or did
not record results requires an explicit enumeration of tests.

For the tests following the default makefile rules, $(tests) (and
$(xtests)) provides such an enumeration.  Others, however, are added
directly as dependencies of the "tests" and "xtests" makefile
targets.  This patch changes the makefiles to put them in variables
tests-special and xtests-special, with appropriate dependencies on the
tests listed there then being added centrally.

Those variables are used in Rules and so need to be set before Rules
is included in a subdirectory makefile, which is often earlier in the
makefile than the dependencies were present before.  We previously
discussed the question of where to include Rules; see the question at
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, and a
discussion in
<https://sourceware.org/ml/libc-alpha/2013-01/msg00337.html> of why
Rules is included early rather than late in subdirectory makefiles.

It was necessary to avoid an indirection through the check-abi target
and get the check-abi-* targets for individual libraries into the
tests-special variable.  The intl/ test $(objpfx)tst-gettext.out,
previously built only because of dependencies from other tests, was
also added to tests-special for the same reason.

The entries in tests-special are the full makefile targets, complete
with $(objpfx) and .out.  If a future change causes tests to be named
consistently with a .out suffix, this can be changed to include just
the path relative to $(objpfx), without .out.

Tested x86_64, including that the same set of files is generated in
the build directory by a build and testsuite run both before and after
the patch (except for changes to the
elf/tst-null-argv.debug.out.<number> file name), and a build with
run-built-tests=no to verify there aren't any more obvious instances
of the issue Marcus Shawcroft reported with a previous version in
<https://sourceware.org/ml/libc-alpha/2014-01/msg00462.html>.

Reviewing the sets of headers for which conformtest has expectations

f8c17e79fa Support expected failures in .test-result files. 
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00195.html>, makes it
possible for .test-result files for individual tests to contain XPASS
and XFAIL rather than PASS and FAIL in cases where failure is
expected.  This replaces the marking of two individual tests with "-"
to cause them to be expected at makefile level to fail;
evaluate-test.sh will ensure it exits with status 0 for an expected
failure.

Tested x86_64.

	* scripts/evaluate-test.sh: Take new argument indicating whether
	failure is expected.
	* Makeconfig (evaluate-test): Pass argument to evaluate-test.sh
	indicating whether failure is expected.

a5f891ac8d Consistently include Makeconfig after defining subdir. 
In <https://sourceware.org/ml/libc-alpha/2014-01/msg00196.html> I
noted it was necessary to add includes of Makeconfig early in various
subdirectory makefiles for the tests-special variable settings added
by that patch to be conditional on configuration information.  No-one
commented on the general question there of whether Makeconfig should
always be included immediately after the definition of subdir.

This patch implements that early inclusion of Makeconfig in each
directory (which is a lot easier than consistent placement of includes
of Rules).  Includes are added if needed, or moved up if already
present.  Subdirectory "all:" targets are removed, since Makeconfig
provides one.

There is potential for further cleanups I haven't done.  Rules and
Makerules have code such as

ifneq   "$(findstring env,$(origin headers))" ""
headers :=
endif

to override to empty any value of various variables that came from the
environment.  I think there is a case for Makeconfig setting all the
subdirectory variables (other than subdir) to empty to ensure no
outside value is going to take effect if a subdirectory fails to
define a variable.  (A list of such variables, possibly out of date
and incomplete, is in manual/maint.texi.)  Rules and Makerules would
give errors if Makeconfig hadn't already been included, instead of
including it themselves.  The special code to override values coming
from the environment would then be obsolete and could be removed.

Tested x86_64, including that installed binaries are identical before
and after the patch.

f0881698bf Generate .test-result files for tests with special rules. 
This patch, an updated version of
<https://sourceware.org/ml/libc-alpha/2014-01/msg00194.html> now
proposed for inclusion in glibc, extends the generation of PASS and
FAIL status in .test-result files for individual tests to cover tests
with their own custom makefile rules.  This is just adding
$(evaluate-test) calls to all such rules, since tests with multiple
commands were previously split into separate tests.

Note that the tests the makefiles expect to fail (posix/annexc and
conformtest) currently get FAIL listed in the .test-result file,
rather than XFAIL; a subsequent patch will introduce a better XFAIL
mechanism.

Tested x86_64.
