* Use existing makefile variables for dependencies on glibc libraries.Joseph Myers2014-05-1610-42/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glibc's Makeconfig defines some variables such as $(libm) and $(libdl) for linking with libraries built by glibc, and nptl/Makeconfig (included by the toplevel Makeconfig) defines others such as $(shared-thread-library). In some places glibc's Makefiles use those variables when linking against the relevant libraries, but in other places they hardcode the location of the libraries in the build tree. This patch cleans up various places to use the variables that already exist (in the case of libm, replacing several duplicate definitions of a $(link-libm) variable in subdirectory Makefiles). (It's not necessarily exactly equivalent to what the existing code does - in particular, $(shared-thread-library) includes libpthread_nonshared, but is replacing places that just referred to libpthread.so. But I think that change is desirable on the general principle of linking things as close as possible to the way in which they would be linked with an installed library, unless there is a clear reason not to do so.) To support running tests with an installed copy of glibc without needing the full build tree from when that copy was built, I think it will be useful to use such variables more generally and systematically - every time the rules for building a test refer to some file from the build tree that's also installed by glibc, use a makefile variable so that the installed-testing case can point those variables to installed copies of the files. This patch just deals with straightforward cases where such variables already exist. It's quite possible some uses of $(shared-thread-library) should actually be a new $(thread-library) variable that's set appropriately in the --disable-shared case, if those uses would in fact work without shared libraries. I didn't change the status quo that those cases hardcode use of a shared library whether or not it's actually needed (but other uses such as $(libm) and $(libdl) would now get the static library if the shared library isn't built, when some previously hardcoded use of the shared library - if they actually need shared libraries, the test itself needs an enable-shared conditional anyway).

* ptsname_r: don't leak uninitialized memory (BZ #16917)Aurelien Jarno2014-05-165-3/+122
| | | | | | | | | | | | | | | If the fd refers to a terminal device, but not a pty master, the TIOCGPTN ioctl returns with ENOTTY. This error is not caught, and the possibly undefined buffer passed to ptsname_r is sent directly to the stat64 syscall. Fix this by using a fallback to the old method only if the TIOCGPTN ioctl fails with EINVAL. This also fix the return value in that specific case (it return ENOENT without this patch). Also add tests to the ptsname_r function (and ptsname at the same time). Note: this is Debian bug#741482, reported by Jakub Wilk <jwilk@debian.org>

| | | | | | | | | | getaddrinfo correctly returns EAI_AGAIN for AF_INET and AF_INET6 queries.

* Fix log1pl (LDBL_MAX) in FE_UPWARD mode (bug 16564).Joseph Myers2014-05-148-11/+311
| | | | | | | | | | | | | | | | | | | | | | | Bug 16564 is spurious overflow of log1pl (LDBL_MAX) in FE_UPWARD mode, resulting from log1pl adding 1 to its argument (for arguments not close to 0), which overflows in that mode. This patch fixes this by avoiding adding 1 to large arguments (precisely what counts as large depends on the floating-point format). Tested x86_64 and x86, and spot-checked log1pl tests on mips64 and powerpc64.

* Fix cacos (+Inf + finite*i) in round-downward mode (bug 16928).Joseph Myers2014-05-148-4/+113
| | | | | | | | | | | | | | | | | | | | | According to C99/C11 Annex G, cacos applied to a value with real part +Inf and finite imaginary part should produce a result with real part +0. glibc wrongly produces a result with real part -0 in FE_DOWNWARD mode. This patch fixes this by checking for zero results in the relevant case of non-finite arguments (where there should never be a result with -0 real part), and converts the tests of cacos to ALL_RM_TEST. Tested x86_64 and x86 and ulps updated accordingly. [BZ #16928] * math/s_cacos.c (__cacos): Ensure zero real part of result from non-finite arguments is +0. * math/s_cacosf.c (__cacosf): Likewise. * math/s_cacosl.c (__cacosl): Likewise. * math/libm-test.inc (cacos_test): Use ALL_RM_TEST. * sysdeps/i386/fpu/libm-test-ulps: Update. * sysdeps/x86_64/fpu/libm-test-ulps: Likewise.
* Fix acosh (1) in round-downward mode (bug 16927).Joseph Myers2014-05-149-5/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to C99 and C11 Annex F, acosh (1) should be +0 in all rounding modes. However, some implementations in glibc wrongly return -0 in round-downward mode (which is what you get if you end up computing log1p (-0), via 1 - 1 being -0 in round-downward mode). This patch fixes the problem implementations, by correcting the test for an exact 1 value in the ldbl-96 implementation to allow for the explicit high bit of the mantissa, and by inserting fabs instructions in the i386 implementations; tests of acosh are duly converted to ALL_RM_TEST. I believe all the other sysdeps/ieee754 implementations are already OK (I haven't checked the ia64 versions, but if buggy then that will be obvious from the results of test runs after this patch is in). Tested x86_64 and x86 and ulps updated accordingly.

* Fix erf underflow handling near 0 (bug 16516).Joseph Myers2014-05-149-23/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug 16516 reports spurious underflows from erf (for all floating-point types), when the result is close to underflowing but does not actually underflow. erf (x) is about (2/sqrt(pi))*x for x close to 0, so there are subnormal arguments for which it does not underflow. The various implementations do (x + efx*x) (for efx = 2/sqrt(pi) - 1), for greater accuracy than if just using a single multiplication by an approximation to 2/sqrt(pi) (effectively, this way there are a few more bits in the approximation to 2/sqrt(pi)). This can introduce underflows when efx*x underflows even though the final result does not, so a scaled calculation with 8*efx is done in these cases - but 8 is not a big enough scale factor to avoid all such underflows. 16 is (any underflows with a scale factor of 16 would only occur when the final result underflows), so this patch changes the code to use that factor. Rather than recomputing all the values of the efx8 variable, it is removed, leaving it to the compiler's constant folding to compute 16*efx. As such scaling can also lose underflows when the final scaling down happens to be exact, appropriate checks are added to ensure underflow exceptions occur when required in such cases. Tested x86_64 and x86; no ulps updates needed. Also spot-checked for powerpc32 and mips64 to verify the changes to the ldbl-128ibm and ldbl-128 implementations.

* Reduce kernel-features.h duplication.Joseph Myers2014-05-1411-129/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reduces duplication between different architectures' kernel-features.h files by making the architecture-independent file define various macros unconditionally (instead of only for a particular list of architectures), with the architecture-specific files then undefining the macros if necessary. Specifically, __ASSUME_O_CLOEXEC (O_CLOEXEC flag to open) and __ASSUME_SOCK_CLOEXEC (SOCK_NONBLOCK and SOCK_CLOEXEC flags to socket) are supported on all architectures as of 2.6.32 or the minimum kernel version for the architecture if later. For __ASSUME_IN_NONBLOCK, __ASSUME_PIPE2, __ASSUME_EVENTFD2, __ASSUME_SIGNALFD4 and __ASSUME_DUP3, the relevant syscalls were added for alpha in 2.6.33 but otherwise the features are available as of 2.6.32. For __ASSUME_UTIMES, support is everywhere in 2.6.32 except for asm-generic architectures and hppa. Although those were the main cases of duplication among kernel-features.h files, some other cases of unnecessary definitions were also cleaned up: the hppa file defined various macros that were either no longer used at all, or defined by the main file by default anyway, the ia64 file had duplicative definitions of __ASSUME_PSELECT and __ASSUME_PPOLL, while mips had such a definition of __ASSUME_IPC64. Really, rather than being defined in the main file then undefined for asm-generic architectures, __ASSUME_UTIMES should become an hppa-specific macro. Given that __ASSUME_ATFCTS and __ASSUME_UTIMENSAT are now always true, the only live __ASSUME_UTIMES conditional is in sysdeps/unix/sysv/linux/utimes.c, which is not used for asm-generic architectures. I think the desired state would be an hppa-specific file (that includes sysdeps/unix/sysv/linux/utimes.c if __ASSUME_UTIMES, and otherwise has fallback code), with the fallback code being removed from the main utimes.c. But I think that's most reasonably a separate cleanup once __ASSUME_ATFCTS and __ASSUME_UTIMESAT have both had conditional code cleaned up. Given this patch, I think it's straightforward to move non-ex-ports architectures to having their own kernel-features.h files, like ex-ports architectures, rather than conditionals in the main file (i.e., such a move won't require the architecture-specific file to contain anything that isn't genuinely architecture-specific), and would encourage architecture maintainers to do so. Tested x86_64 that the installed shared libraries are unchanged by this patch. Note that on some architectures this *will* cause __ASSUME_* macros to be defined in cases where they weren't previously but should have been (but this is just optimization, not a fix to a user-visible bug, so doesn't need a bug report in Bugzilla). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Define unconditionally.

* Clean up ARM old-ABI symbol versioning relics.Joseph Myers2014-05-149-99/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up some symbol versioning code in the ARM port that exists only as relics of the old-ABI port, which was removed some time ago. The minimum symbol version in the ARM port is GLIBC_2.4 (the version where the EABI port was introduced). Thus, any SHLIB_COMPAT conditionals where the later version is 2.4 or later are obsolete and can be removed. In addition, there is no need to set symbol versions before 2.4 explicitly if the symbols would have a version of 2.4 by default anyway. This includes most of the entries in sysdeps/unix/sysv/linux/arm/Versions: those for GLIBC_2.0 are for libgcc unwind functions that aren't actually in ARM EABI glibc at all, while those for GLIBC_2.2 and GLIBC_2.3.3 are for functions which for the old-ABI port may have had versions different from the architecture-independent default, but where for EABI the default suffices (both the default and the version in that file map to 2.4, so the entries in that file do nothing). The GLIBC_2.1 entries are needed (architecture-specific functions), but it seems less confusing for those to say GLIBC_2.4, as the actual version those symbols in fact have. Various cases in the <fenv.h> functions where a function is defined as __fe* with an fe* versioned alias are cleaned up just to define fe* directly, as done e.g. on AArch64. If in future we actually need an __fe* name for use from C90 functions in libm as discussed recently, of course we can add one on all architectures and make the fe* name into a weak alias for that particular function, but for now the __fe* names aren't needed. In the case of posix_fadvise64, the __posix_fadvise64_l64 name and posix_fadvise64 alias are kept as __posix_fadvise64_l64 is used in posix_fadvise. (For that to be a namespace-clean use, posix_fadvise64 needs to be a *weak* alias not a strong one as at present, but that's an independent preexisting bug.) (There remain references to GLIBC_2_2 in sysdeps/unix/sysv/linux/arm/{msgctl.c,semctl.c,shmctl.c}. As those files are used by alpha which has a genuine 2.2 version for those functions, I think those references need to stay as-is.) Tested that the disassembly of installed shared libraries is unchanged by this patch (though function names shown in disassembly change to no longer have @@GLIBC_2.4, now those functions get versioned only by the version map and not redundantly at assembler time) and that the ABI tests pass. * sysdeps/arm/fclrexcpt.c (__feclearexcept): Rename to feclearexcept.

* Clean up kernel version conditionals for pre-2.6.32 kernels.Joseph Myers2014-05-128-162/+126

In the case of __ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel version that was itself in a macro, the associated sysconf.c code is also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely. Tested x86_64 that disassembly of installed shared libraries is unchanged by the patch. * sysdeps/unix/sysv/linux/kernel-features.h [__s390__] (__ASSUME_UTIMES): Do not condition on kernel version.
