2017-03-20conformtest: Add x32 XFAILs for mq_attr element types (bug 21279).Joseph Myers1-4/+5
POSIX specifies long as the type of elements of struct mq_attr. For x32, they are __syscall_slong_t (i.e. long long). This patch XFAILs the corresponding tests for x32 in the conformtest expectations (the bug should not be closed without an actual fix). Tested with build-many-glibcs.py. [BZ #21279] * sysdeps/unix/sysv/linux/x86_64/x32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): Update comment. * conform/data/mqueue.h-data (mq_attr.mq_flags): XFAIL for x86_64-x32-linux. (mq_attr.mq_maxmsg): Likewise. (mq_attr.mq_msgsize): Likewise. (mq_attr.mq_curmsgs): Likewise.
2017-03-20conformtest: Add mips XFAIL for struct stat st_rdev type (bug 21278).Joseph Myers1-1/+2
MIPS o32 struct stat has the wrong type of st_rdev. This patch XFAILs that test in the conformtest expectations for this case (the bug should not be closed without an actual fix, however). Tested with build-many-glibcs.py. [BZ #21278] * sysdeps/unix/sysv/linux/mips/mips32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): Update comment. * conform/data/sys/stat.h-data (stat.st_rdev): XFAIL for mips-o32-linux.
2017-03-18conformtest: XFAIL tv_nsec tests for x32 (bug 16437).Joseph Myers4-4/+8
This patch XFAILs the conformtest tv_nsec tests for x32 so that the incorrect type does not potentially hide other failures. As this is not a fix for the bug, it should remain open in Bugzilla. Tested (compilation only) with build-many-glibcs.py. [BZ #16437] * sysdeps/unix/sysv/linux/x86_64/x32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): New variable. * conform/data/signal.h-data (timespec.tv_nsec): XFAIL for x86_64-x32-linux. * conform/data/sys/select.h-data (timespec.tv_nsec): Likewise. * conform/data/sys/stat.h-data (timespec.tv_nsec): Likewise. * conform/data/time.h-data (timespec.tv_nsec): Likewise.
2017-03-18conformtest: Handle conditional XFAILs with allow-header.Joseph Myers1-1/+1
This patch fixes the conformtest handling of headers listed in allow-header to process xfail[cond]- in the expectations for those headers. Tested with build-many-glibcs.py. * conform/conformtest.pl: Handle xfail[cond]- in header mentioned with allow-header.
2017-03-17conformtest: Add mips XFAIL for struct stat st_dev type (bug 17786).Joseph Myers1-1/+2
As noted in bug 17786, MIPS o32 struct stat has the wrong type of st_dev. This patch XFAILs that test in the conformtest expectations for this case (the test still fails after the patch because there's also a similar issue for st_rdev that needs reporting and XFAILing separately, and the bug should not be closed without an actual fix, not just XFAILing). Tested for mips with build-many-glibcs.py. [BZ #17786] * sysdeps/unix/sysv/linux/mips/mips32/Makefile: New file. * conform/data/sys/stat.h-data (stat.st_dev): XFAIL for mips-o32-linux.
2017-03-17conformtest: Add alpha XFAIL for struct netent n_net type (bug 21260).Joseph Myers1-1/+2
As noted in bug 21260, sysdeps/unix/sysv/linux/alpha/bits/netdb.h defines struct netent with n_net of type unsigned long instead of the correct uint32_t. This patch XFAILs that test in the conformtest expectations for alpha. (This is not a fix for the bug, and it should not be closed without an actual fix.) Tested for alpha with build-many-glibcs.py. [BZ #21260] * sysdeps/unix/sysv/linux/alpha/Makefile [$(subdir) = conform] (conformtest-xfail-conds): New variable.
2017-03-17conformtest: Skip execution tests when cross-compiling.Joseph Myers2-2/+11
This patch makes conformtest skip execution tests when cross-compiling, as an interim step towards running most of these tests (presently disabled) in that case. It omits the (obvious) Makefile change to actually enable the conformtest tests when cross-compiling, as there are still enough failures seen with build-many-glibcs.py that I'd like to get the results cleaner before enabling these tests. Tested for x86_64, and with the tests actually enabled for cross-compilation with build-many-glibcs.py. * conform/conformtest.pl ($cross): New variable. (--cross): New command-line option. (runtest): Skip test execution when cross-compiling. * conform/Makefile (conformtest-cross): New variable. ($(conformtest-header-tests)): Pass $(conformtest-cross) to conformtest.pl.
2017-03-17conformtest: Support system-specific XFAILs.Joseph Myers2-2/+18
conformtest has an internal XFAIL mechanism to allow failures of individual expectations to be ignored, so that known hard-to-fix failures (e.g. those affecting ABIs or requiring kernel changes) do not cause the overall tests to FAIL and so hide other failures from the same (header, standard) pair. Various such bugs are system-specific, so this patch adds a mechanism to allow system-specific XFAILs. A system-independent XFAIL is achieved by putting "xfail-" at the start of the relevant expectation in the *-data files. A system-specific XFAIL instead uses "xfail[cond]-", where "cond" is a condition listed in conformtest-xfail-conds in a sysdeps makefile (so one for x32 might set conformtest-xfail-conds = x86_64-x32-linux, for example, and then an expectation for tv_nsec's type could use xfail[x86_64-x32-linux]-). The actual names are arbitrary, just needing to match between the makefiles and the expectations, and if necessary you can use "xfail[cond1|cond2]-" for a test that is expected to fail under multiple conditions. As with system-independent XFAILs, I think system-specific ones should have a bug filed in Bugzilla and a comment referencing that bug. Tested for x86_64, including with test expectations and makefiles changed to use the new facility. * conform/conformtest.pl ($xfail_str): New variable. (--xfail=): New command-line option. (top level): Handle expectations starting xfail[cond]-. * conform/Makefile (conformtest-xfail): New variable. ($(conformtest-header-tests)): Pass $(conformtest-xfail) to conformtest.pl.
2017-03-16conformtest: Make more tests into compilation tests.Joseph Myers1-8/+7
The conformtest header tests test some things through compilation tests and others through execution tests. This patch makes more of the tests into compilation tests, using _Static_assert (note: for float.h tests on floating-point values this is depending on a GNU extension, that those assertions are allowed in the absence of -pedantic although they aren't strictly integer constant expressions). The remaining execution tests are for values of things listed as "symbol" (in fact no such things have a value expectation listed) and for values of macros defined as string constants (three such values listed in total). This is intended as preparation for enabling the vast bulk of the tests to run for cross compilation. (Even the few remaining execution tests ought in principle to run for cross compilation when a test wrapper is defined, but that's more complicated. The existing execution tests for native builds in fact are linked and run with an existing installed libc that's required to exist to link against, rather than with the newly built libc; only the new headers are used.) Tested for x86_64. * conform/conformtest.pl: Use compilation instead of execution tests for testing values of constants and usability in #if.

2016-11-16Enable linknamespace testing for libdl and libcrypt.Joseph Myers1-9/+14
When I set up linknamespace testing, the lists of libraries that might contain functions from various standards were based on the -l options POSIX says may be required to find certain functions with the c99 utility. glibc has some POSIX functions in the libdl and libcrypt libraries, not mentioned in the definition of the c99 utility (so an implementation of that utility using glibc would need to use -ldl -lcrypt automatically). This patch adds those libraries to the ones considered in linknamespace testing for relevant standards. (The crypt functions are XSI only, present in XPG3 and above; the libdl ones were added in UNIX98, then moved from XSI to BASE in the 2008 edition of POSIX.) * conform/Makefile (linknamespace-libs): Rename to linknamespace-libs-thr. (linknamespace-libs-posix): New variable. (linknamespace-libs-xsi): Likewise. (linknamespace-libs-XPG3): Include libcrypt.a. (linknamespace-libs-XPG4): Use $(linknamespace-libs-XPG3). (linknamespace-libs-POSIX): Use $(linknamespace-libs-thr). (linknamespace-libs-UNIX98): Use $(linknamespace-libs-xsi). (linknamespace-libs-XOPEN2K): Likewise. (linknamespace-libs-XOPEN2K8): Likewise. (linknamespace-libs-POSIX2008): Use $(linknamespace-libs-posix).
2016-11-03Fix linknamespace parallel test failures.Joseph Myers1-0/+1
Having found that with my script to build many glibc variants I could reproduce the linknamespace test failures in parallel builds (that various people had previously reported but I hadn't seen myself), I investigated those failures further. This patch adds a missing dependency to those tests. Tested for x86_64, including the configuration where I saw those failures and where I don't see them with this patch. * conform/Makefile ($(linknamespace-header-tests)): Also depend on $(linknamespace-symlists-tests).
2016-09-05conform tests: call perl with '-I.'Aurelien Jarno1-3/+3
Historically perl includes the current directory in the module search path. Over the time this has been considered as a security issue and the recent vulnerabilities [1] made people to reconsider this behaviour. It is almost sure that this will be removed in the future [2], possibly for the 5.26 release, although this is not yet firmly decided. Debian has decided to backport the patches [3], so the perl binary in unstable do not have '.' in @INC anymore. This behaviour is used in the conform perl scripts to include the GlibcConform module. This patch fixes that by calling perl with '-I.'. This is not a security issue in this case as make ensures that the current directory is $(srcdir)/conform/ when the scripts are called. Passing the full path would do exactly the same. [1] CVE-2016-1238 CVE-2016-6185 [2] https://rt.perl.org/Public/Bug/Display.html?id=127810 [3] https://lists.debian.org/debian-devel-announce/2016/08/msg00013.html Changelog: * conform/Makefile (conformtest-header-tests): Pass -I. to $(PERL).

2016-06-10Revert {send,sendm,recv,recvm}msg conformance changesAdhemerval Zanella1-3/+5
After some discussion in libc-alpha about this POSIX compliance fix, I see that GLIBC should indeed revert back to previous definition of msghdr and cmsghdr and implementation of sendmsg, recvmsg, sendmmsg, recvmmsg due some reasons: * The possible issue where the syscalls wrapper add the compatibility layer is quite limited in scope and range. And kernel current also add some limits to the values on the internal msghdr and cmsghdr fields: - msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns EMSGSIZE. - msghdr::msg_controllen larger than INT_MAX returns ENOBUFS. * There is a small performance hit for recvmsg/sendmsg/recmmsg which is neglectable, but it is a big hit for sendmmsg since now instead of calling the syscall for the packed structure, GLIBC is calling multiple sendmsg. This defeat the very existence of the syscall. * It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt). However the fix is incomplete because it does add any runtime check since libsanitizer currently does not have any facility to intercept symbols with multiple version [2]. This, along with incorret dlsym/dlvsym return for versioned symbol due another bug [3], makes hard to interpose versioned symbols. Also, current approach of fixing GCC PR#71445 leads to half-baked solutions without versioned symbol interposing. This patch basically reverts commits 2f0dc39029ae08, 222c2d7f4357d66, af7f7c7ec8dea1. I decided to not revert abf29edd4a3918 (Adjust kernel-features.h defaults for recvmsg and sendmsg) mainly because it does not really address the POSIX compliance original issue and also adds some cleanups. Tested on x86, i386, s390, s390x, aarch64, and powerpc64le.

2016-05-25network: recvmsg and sendmsg standard compliance (BZ#16919)Adhemerval Zanella1-5/+3
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int. Also the new recvmsg and sendmsg implementation is only added on libc, with libpthread only containing a compat symbol. Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * conform/data/sys/socket.h-data (msghdr.msg_iovlen): Remove xfail- and change to correct expected type. (msghdr.msg_controllen): Likewise.

stdlib.h declares rand_r if __USE_POSIX; i.e., POSIX.1:1990. But rand_r was added along with threads, so the condition should be __USE_POSIX199506. This patch corrects the condition. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2016-05-17Correct ttyslot header declaration conditions (bug 20051).Joseph Myers1-2/+0
UNIX98 and XPG4 have ttyslot in <stdlib.h>. glibc, however, has it in <unistd.h>, for __USE_MISC || (__USE_XOPEN_EXTENDED && !__USE_UNIX98), but no supported standard has it in <unistd.h>. This patch adds a properly conditioned declaration to <stdlib.h> (only enabled for the relevant standards, not for __USE_MISC or __USE_GNU). The <unistd.h> declaration is restricted to __USE_MISC. Some relevant XFAILs are removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

The conformtest tests of unistd.h fail for XPG3 because of various expectations that are incorrect for XPG3. This patch corrects those bogus expectations, and one bogus expectation for XPG4.

unistd.h declares gethostname for __USE_UNIX98 || __USE_XOPEN2K. But it's also in XPG4 (XNS volume - C438 - not the main definitions of system interfaces and headers in C435). This patch corrects the condition. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2016-05-12conformtest: Do not expect S_IF* in fcntl.h.Joseph Myers2-11/+0
The conform/ tests for fcntl.h are failing for XPG3 and XPG4 because of missing S_IFSOCK. This is a case of a bogus test. The relevant wording requiring such constants is, in current POSIX (and this requirement dates back as far as XPG4), "The <fcntl.h> header shall define the symbolic constants for file modes for use as values of mode_t as described in <sys/stat.h>.". Note that this is *file modes* not *file types*. That makes sense, since the point is presumably for use with functions such as open that are declared in fcntl.h, where file modes are relevant but file types aren't. So this patch removes all those spurious S_IF* expectations for fcntl.h (the macros are generally still *allowed* through the permission to make everything from sys/stat.h visible).

termios.h should declare tcgetsid for XPG4, but only does so for __USE_UNIX98 || __USE_XOPEN2K8 at present. This patch fixes the declaration conditions. A spurious conformtest expectation of this declaration for XPG3 is removed, and two XFAILs that are fixed by these changes are also removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

2016-05-10Fix sys/stat.h fchmod namespace (bug 20073).Joseph Myers1-1/+0
sys/stat.h declares fchmod if __USE_POSIX (i.e. POSIX.1:1990). But it was actually added in 1993 and also in XPG4. This patch changes the conditions to the correct __USE_POSIX199309 || __USE_XOPEN_EXTENDED. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20073] * io/sys/stat.h (fchmod): Declare for [__USE_POSIX199309 || __USE_XOPEN_EXTENDED], not [__USE_POSIX]. * conform/Makefile (test-xfail-XPG3/sys/stat.h/conform): Remove variable.

This patch fixes various conformtest sys/stat.h expectations that were incorrect for XPG3 (not based on a full review, so not necessarily an exhaustive set of such corrections). Most of these corrections fix spurious failures shown in testing (but that for fchmod introduces a correct failure, as that function is wrongly declared for XPG3, so this doesn't eliminate any XFAILs).

2016-05-10conformtest: Fix st_blksize, st_blocks expectations for XPG3, XPG4.Joseph Myers1-1/+9
The conformtest expectations expect the struct stat fields st_blksize and st_blocks to be of types blksize_t and blkcnt_t. But XPG4 does not have those types, using long instead, and XPG3 does not have these fields at all. This patch adjusts the expectations for those standards, XFAILing them for XPG4 to allow for systems where the typedefs don't correspond to long. Tested for x86_64 and x86. * conform/data/sys/stat.h-data (st_blksize): Do not expect for [XPG3]. Expect type long and XFAIL for [XPG4]. (st_blocks): Likewise.
2016-05-10Declare pthread_atfork in unistd.h for UNIX98 (bug 20044).Joseph Myers1-1/+0
For UNIX98 (only), unistd.h should declare pthread_atfork, but that declaration is missing. This patch adds it.

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. * conform/data/sys/types.h-data (blkcnt_t): Do not expect for [XPG3 || XPG4]. (blksize_t): Likewise.

2016-05-03Fix sys/time.h timespec namespace (bug 20041).Joseph Myers1-4/+0
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). [BZ #20041] * misc/sys/select.h (__need_timespec): Only define if [__USE_XOPEN2K]. * conform/Makefile (test-xfail-XPG4/sys/time.h/conform): Remove variable.

2016-05-02Fix fcntl.h timespec namespace (bug 20023).Joseph Myers1-2/+0
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 shared libraries are unchanged by the patch). [BZ #20023] * io/fcntl.h [__USE_XOPEN && !__USE_XOPEN2K8]: Do not include <time.h>. * conform/Makefile (test-xfail-UNIX98/fcntl.h/conform): Remove variable.

2016-04-28Fix stdio.h namespace for pre-threads POSIX (bug 20014).Joseph Myers1-2/+0
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. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #20014] * libio/stdio.h (getc_unlocked): Declare if [__USE_POSIX199506], not [__USE_POSIX].

2016-04-28Also define off_t in stdio.h for UNIX98.Joseph Myers1-1/+0
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. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * libio/stdio.h (off_t): Also define if [__USE_UNIX98].

2016-04-27conformtest: Correct some stdio.h expectations for UNIX98.Joseph Myers1-6/+6
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.) Tested for x86_64 and x86. * conform/data/stdio.h-data (flockfile): Also expect for [UNIX98]. (fseeko): Likewise. (ftello): Likewise. (ftrylockfile): Likewise. (funlockfile): Likewise.

2016-04-27conformtest: Correct some signal.h expectations for XOPEN2K.Joseph Myers2-3/+1
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. Tested for x86_64 and x86. * conform/data/signal.h-data (union sigval): Expect also if [XOPEN2K]. (struct sigevent): Likewise. (SIGEV_NONE): Likewise. (SIGEV_SIGNAL): Likewise. (SIGEV_THREAD): Likewise. (SIGRTMIN): Likewise.

langinfo.h declares nl_langinfo_l if __USE_XOPEN2K. But this function was new in the 2008 edition of POSIX. This patch fixes the condition accordingly. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch).

2016-04-26Define off_t in stdio.h for XOPEN2K.Joseph Myers1-1/+0
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). * libio/stdio.h (off_t): Define if [__USE_XOPEN2K], not [__USE_XOPEN2K8]. [__USE_LARGEFILE64] (off64_t): Likewise. * conform/Makefile (test-xfail-XOPEN2K/stdio.h/conform): Remove variable.
2016-04-25Fix stdio.h cuserid namespace (bug 19989).Joseph Myers1-1/+0
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. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). [BZ #19989] * libio/stdio.h (cuserid): Do not declare if [__USE_XOPEN2K && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/stdio.h/conform): Remove variable.
2016-04-08Fix limits.h NL_NMAX namespace (bug 19929).Joseph Myers1-1/+0
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". Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #19929] * include/bits/xopen_lim.h (NL_NMAX): Do not define if [__USE_XOPEN2K8 && !__USE_GNU]. * conform/Makefile (test-xfail-XOPEN2K8/limits.h/conform): Remove variable.

bits/termios.h (various versions under sysdeps/unix/sysv/linux) 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).
