* Fix alpha termios.h NL2, NL3 namespace (bug 21268).Joseph Myers2017-03-202-2/+11
| | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/alpha/bits/termios.h defines NL2 and NL3 for __USE_MISC || __USE_XOPEN. These should only be defined for __USE_MISC as they are not part of any standard namespace. This patch conditions them accordingly, matching the powerpc version of the header (the only other one in glibc that defines these macros). Tested (compilation only) with build-many-glibcs.py. [BZ #21268] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (NL2): Define only if [__USE_MISC] (NL3): Likewise.
* posix_spawn: fix stack setup on ia64 [BZ #21275]Mike Frysinger2017-03-202-5/+14
| | | | | | | | | The ia64-specific clone2 call expects the base of the stack mapping and the stack size as sep arguments, not an initial stack value as on other stack-grows-down architectures. Reuse the stack-grows-up macro so we pass in the right stack base. Reported-by: Matt Turner <mattst88@gentoo.org>
* linux ttyname and ttyname_r: do not return wrong resultsChristian Brauner2017-03-194-8/+71
| | | | | | | | | | | | | If a link (say /proc/self/fd/0) pointing to a device, say /dev/pts/2, in a parent mount namespace is passed to ttyname, and a /dev/pts/2 exists (in a different devpts) in the current namespace, then it returns /dev/pts/2. But /dev/pts/2 is NOT the current tty, it is a different file and device. Detect this case and return ENODEV. Userspace can choose to take this as a hint that the fd points to a tty device but to act on the fd rather than the link.

* conformtest: XFAIL tv_nsec tests for x32 (bug 16437).Joseph Myers2017-03-186-4/+22
| | | | | | | | | | | | | | | | | 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.
* Fix sparc64 bits/setjmp.h namespace (bug 21261).Joseph Myers2017-03-183-21/+30
| | | | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/sparc/bits/setjmp.h defines 64-bit __jmp_buf with a load of identifiers that are not part of any standard namespace, resulting in conform/ tests failing. This patch fixes this by moving those identifiers to the implementation namespace, so enabling the conform/ tests to pass for sparc64. Tested (compilation only) for sparc64 with build-many-glibcs.py. [BZ #21261] * sysdeps/unix/sysv/linux/sparc/bits/setjmp.h [__WORDSIZE == 64 && !_ASM] (__sparc64_jmp_buf): Use reserved names for all fields. * sysdeps/sparc/sparc64/jmpbuf-unwind.h (_JMPBUF_UNWINDS): Update for jmp_buf field renaming. (_JMPBUF_UNWINDS_ADJ): Likewise.
* conformtest: Handle conditional XFAILs with allow-header.Joseph Myers2017-03-182-1/+6
| | | | | | | | | | | 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.
* Further harden glibc malloc metadata against 1-byte overflows.DJ Delorie2017-03-172-0/+7

* Make alpha termios.h define IXANY unconditionally (bug 21259).Joseph Myers2017-03-172-1/+5
| | | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if __USE_MISC. But it's in the base standard for POSIX.1:2008, and XSI-shaded in previous standards. This patch makes the header define it unconditionally, like other versions of this header do (it's always reserved by standards that don't require it, so defining unconditionally is OK by the standards). Tested (compilation only) for alpha with build-many-glibcs.py. Note that there are still termios.h conformtest failures after this patch because of other issues with the alpha version of this header. [BZ #21259] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (IXANY): Define unconditionally, not just for [__USE_MISC].
* conformtest: Add mips XFAIL for struct stat st_dev type (bug 17786).Joseph Myers2017-03-173-1/+11
| | | | | | | | | | | | | | | | 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.

* conformtest: Add alpha XFAIL for struct netent n_net type (bug 21260).Joseph Myers2017-03-173-1/+11
| | | | | | | | | | | | | | 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 [$(subdir) = conform] (conformtest-xfail-conds): New variable.
* conformtest: Skip execution tests when cross-compiling.Joseph Myers2017-03-173-2/+18
| | | | | | | | | | | | | | | | | | | | This patch makes conformtest skip execution tests when cross-compiling, as an interim step towards running most of these tests (presently disabled) in that case. It omits the (obvious) Makefile change to actually enable the conformtest tests when cross-compiling, as there are still enough failures seen with build-many-glibcs.py that I'd like to get the results cleaner before enabling these tests. Tested for x86_64, and with the tests actually enabled for cross-compilation with build-many-glibcs.py. * conform/conformtest.pl ($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 $(conformtest-cross) to conformtest.pl.
* conformtest: Support system-specific XFAILs.Joseph Myers2017-03-173-2/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | conformtest has an internal XFAIL mechanism to allow failures of individual expectations to be ignored, so that known hard-to-fix failures (e.g. those affecting ABIs or requiring kernel changes) do not cause the overall tests to FAIL and so hide other failures from the same (header, standard) pair. Various such bugs are system-specific, so this patch adds a mechanism to allow system-specific XFAILs. A system-independent XFAIL is achieved by putting "xfail-" at the start of the relevant expectation in the *-data files. A system-specific XFAIL instead uses "xfail[cond]-", where "cond" is a condition listed in conformtest-xfail-conds in a sysdeps makefile (so one for x32 might set conformtest-xfail-conds = x86_64-x32-linux, for example, and then an expectation for tv_nsec's type could use xfail[x86_64-x32-linux]-). The actual names are arbitrary, just needing to match between the makefiles and the expectations, and if necessary you can use "xfail[cond1|cond2]-" for a test that is expected to fail under multiple conditions. As with system-independent XFAILs, I think system-specific ones should have a bug filed in Bugzilla and a comment referencing that bug. Tested for x86_64, including with test expectations and makefiles changed to use the new facility. * conform/conformtest.pl ($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.
* conformtest: Make more tests into compilation tests.Joseph Myers2017-03-162-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* XFAIL catan and catanh tests on ibm128Tulio Magno Quites Machado Filho2017-03-164-1168/+1175
| | | | | | | | | | | | | | | Mark 4 catan and catanh tests as xfail-rounding:ibm128-libgcc. After this patch all catan and catanh tests pass on ibm128. Regenerated auto-libm-test-out using gmp 6.1.2, mpfr 3.1.5 and upstream mpc (9ef8030e50), Tested on powerpc, powerpc64 and powerpc64le. * math/auto-libm-test-in: Mark some catan and catanh as xfail-rounding:ibm128-libgcc. * math/auto-libm-test-out-catan: Regenerate. * math/auto-libm-test-out-catanh: Likewise.
* Remove C++ namespace handling from glibc headers.Joseph Myers2017-03-1625-411/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

| | | | | | | | | | | | When glibc is compiled with gcc 6.2 that has been configured with to default to PIC/PIE, the static version of __mempcpy_chk is not built, as the test is done on PIC instead of SHARED.

* Improve float range reduction accuracy near pi/2 (bug 21094).Joseph Myers2017-03-155-2/+595
| | | | | | | | | | | | | | | | | | | | | | | | | Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments near pi/2 arising from the use of an insufficiently accurate range reduction. (To be clear, this is a quality-of-implementation issue relating to the apparent intent of those particular cosf and tanf implementations; 3ulp is within the general glibc accuracy goals, so not inherently a bug.) This patch fixes that error by making a wider range of cases use the existing more accurate range reduction for arguments close to pi/2. The wider range of values is still narrow enough for the "z -= pio2_2;" in the more accurate case to be exact, as the code expects. Tested for x86_64, x86 and mips64; no ulps updates needed (but at least on mips64, the larger ulps were seen if the tests were added without the substantive fix). [BZ #21094] * sysdeps/ieee754/flt-32/e_rem_pio2f.c (__ieee754_rem_pio2f): Use 24+24+24-bit pi for wider range of values around pi/2. * math/auto-libm-test-in: Add more tests of cos and tan. * math/auto-libm-test-out-cos: Regenerated. * math/auto-libm-test-out-tan: Likewise.
* hppa: Fix setting of __libc_stack_endJohn David Anglin2017-03-152-5/+9
| | | | | | | | | | | | | | The binutils package was recently changed to fix -z relro support on hppa. See ld/21000 for details: https://sourceware.org/bugzilla/show_bug.cgi?id=21000 This exposed a problem with the _dl_start_user function in the RTLD_START define. We need to set __libc_stack_end before it is made read only. For this, we need to define DL_STACK_END. The offset of 0x160 gives the same stack end as the code in _dl_start_user. A build log with the attached patch is here: https://buildd.debian.org/status/fetch.php?pkg=glibc&arch=hppa&ver=2.24-9&stamp=1487639205&raw=0

* Fix combreloc test with BSD grepAlexey Neyman2017-03-153-9/+14
| | | | | | | | | | | | | | The test for "-z combreloc" fails when cross-compiling on a machine that uses BSD grep (e.g. on macos). grep complains about empty subexpression and exits with non-zero status, which is interpreted by configure as "not found". As a result, support for "-z combreloc" (HAVE_Z_COMBRELOC) is not detected, leading to link failure on SPARC. While there, replace fgrep with 'grep -F', as fgrep is non-POSIX. * configure.ac: Avoid empty subexpression in grep. Signed-off-by: Alexey Neyman <stilor@att.net>
* Fix test-errno issuesAdhemerval Zanella2017-03-154-9/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes multiple issues of test-errno.c (9a56f8718341): - Rename Linux test-errno.c to test-errno-linux.c to avoid build the same source for both tests. - Add a mlock check for 32 bits build running on 64 bits kernels. Althuough man pages states that mlock fails with EINVAL if final address overflows, kernels does not return it for aforementioned condition (it returns ENOMEM instead). Although it seems to be a kernel issue for compat syscall handling, I think it is worth to still check syscall return and document the behavior. - Initialize option lenght for setsockopt check. - Change open test from EINVAL to EISDIR. Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits kernel). * posix/test-errno.c (do_test): Initialize setsockopt optlen. * sysdeps/unix/sysv/linux/test-errno.c: Move to ... * sysdeps/unix/sysv/linux/test-errno-linux.c: ... here.

* Fix test-math-vector-sincos.h aliasing.Joseph Myers2017-03-152-14/+23
| | | | | | | | | | | | | | | | | | | | | x86_64 libmvec tests have been failing to build lately with GCC mainline with -Wuninitialized errors, and Markus Trippelsdorf traced this to an aliasing issue <https://sourceware.org/ml/libc-alpha/2017-03/msg00169.html>. This patch fixes the aliasing issue, so that the vectors-of-pointers are initialized using a union instead of pointer casts. This also fixes the testsuite build failures with GCC mainline. Tested for x86_64 (full testsuite with GCC 6; testsuite build with GCC mainline with build-many-glibcs.py). * sysdeps/x86/fpu/test-math-vector-sincos.h (INIT_VEC_PTRS_LOOP): Use a union when storing pointers.

* Split helper classification macros from mathcalls.hGabriel F. T. Gomes2017-03-156-29/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The classification macros: finite, fpclassify, iseqsig, isinf, isnan, issignaling, and signbit are defined by ISO C11 and declared in mathcalls.h for each of the floating-point types: float, double, and long double. TS 18661-3 does not mention these macros for float128, however support for them must be present when _Float128 is present. This is true, even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Other function declarations in mathcalls.h, on the other hand, depend on __STDC_WANT_IEC_60559_TYPES_EXT__. This patch splits the helper functions (__finite, __fpclassify, __iseqsig, __isinf, __isnan, __issignaling, and __signbit) from mathcalls.h, so that these helper functions can be declared for _Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false. Tested for powerpc64le, s390x, and x86_64. * include/bits/mathcalls-helper-functions.h: New file. * math/Makefile (headers): Add bits/mathcalls-helper-functions.h. * math/bits/mathcalls.h (__finite, __fpclassify, __iseqsig) (__isinf, __isnan, __issignaling, __signbit): Move declarations to math/bits/mathcalls-helper-functions.h. * math/bits/mathcalls-helper-functions.h: New file. * math/math.h: Include bits/mathcalls-helper-functions.h for float, double, and long double.

| | | | | | | | | | | | | | | | | | | | | Linux 4.10 adds IPV6_RECVFRAGSIZE to include/uapi/linux/in6.h, which shows that several such IPV6_* macros are missing from glibc's sysdeps/unix/sysv/linux/bits/in.h (while older ones are present). I don't know whether any of these might be deliberately omitted, but this patch adds what appear to be the missing more recent macros to glibc. Tested for x86_64. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_AUTOFLOWLABEL): New macro. (IPV6_ADDR_PREFERENCES): Likewise. (IPV6_MINHOPCOUNT): Likewise. (IPV6_ORIGDSTADDR): Likewise. (IPV6_RECVORIGDSTADDR): Likewise. (IPV6_TRANSPARENT): Likewise. (IPV6_UNICAST_IF): Likewise. (IPV6_RECVFRAGSIZE): Likewise.

* sh: Fix building with gcc5/6Alexey Neyman2017-03-122-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Build glibc for sh4-unknown-linux-gnu currently fails if one's using GCC5/6: in dl-conflict.c, the elf_machine_rela() function is called with NULL as its 3rd argument, sym. The implementation of that function in sysdeps/sh/dl-machine.h dereferences that pointer: const Elf32_Sym *const refsym = sym; ... if (map == &GL(dl_rtld_map)) value -= map->l_addr + refsym->st_value + reloc->r_addend; GCC discovers a null pointer dereference, and in accordance with -fdelete-null-pointer-checks (which is enabled in -O2) replaces this code with a trap - which, as SH does not implement a trap pattern in GCC, evaluates to an abort() call. This abort() call pulls many more objects from libc_nonshared.a, eventually resulting in link failure due to multiple definitions for a number of symbols. As far as I see, the conditional before this code is always false in rtld: _dl_resolve_conflicts() is called with main_map as the first argument, not GL(_dl_rtld_map), but since that call is in yet another compilation unit, GCC does not know about it. Patch that wraps this conditional into !defined RESOLVE_CONFLICT_FIND_MAP attached. * sysdeps/sh/dl-machine.h (elf_machine_rela): The condition in R_SH_DIR32 case is always false when inlined from dl-conflict.c. Ifdef out to prevent GCC from insertin an abort() call.

* Update auto-libm-test-out for catan / catanh.Stefan Liebler2017-03-104-912/+918
| | | | | | | | | | | | | | I've used gmp 6.1.2, mpfr 3.1.5 and upstream mpc with fix in mpc_atan (https://scm.gforge.inria.fr/anonscm/gitweb?p=mpc/mpc.git;a=commit;h=958aac9b15a659d6fb5edcb11778123f8a35b14f) to build gen-auto-libm-tests and regenerated catan / catanh out files.

* Regenerate MIPS catan, catanh long double ulps.Joseph Myers2017-03-092-16/+21
| | | | | | | | | | | | This patch regenerates MIPS catan and catanh ulps for long double with fixed expected results for the tests of those functions. ulps for other types (which may see variation depending on whether glibc is built for a processor with fused multiply-add support) are deliberately not reduced. ulps are not regenerated for powerpc-nofpu as such regeneration does not result in any changes for long double. * sysdeps/mips/mips64/libm-test-ulps: Update catan and catanh ulps for long double with corrected test expectations.
