2017-02-28sunrpc: Improvements for UDP client timeout handling [BZ #20257]Florian Weimer
This commit fixes various aspects in the UDP client timeout handling. Timeouts are now applied in a more consistent fashion. Discarded UDP packets no longer prevent the timeout from happening at all.
2017-02-28sunrpc: Do not unregister services if not registered [BZ #5010]Florian Weimer
The change in commit 718946816cf60374f9d8f674d3ed649fdb33205a has no effect because of two bugs which cancel each other out: The svc_is_mapped condition is inverted, and svc_is_mapped always returns false because the check is performed after the service has already been unregistered. As a result, pmap_unset is called unconditionally, as before.

The <bits/sigthread.h> header is included by <signal.h>, not <pthread.h>.
2017-02-27sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]Florian Weimer
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c (CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call [BZ #20112]), ancillary data is stored on the heap, but it is accessed after it has been freed. The test case must be run under a heap debugger such as valgrind to observe the invalid access. A malloc implementation which immediately calls munmap on free would catch this bug as well.
2017-02-25Allow direct use of math_ldbl.h in testsuite.Zack Weinberg
A few 'long double'-related tests include math_private.h just for their variety of math_ldbl.h, which contains macros for assembling and disassembling the binary representation of 'long double'. math_ldbl.h insists on being included from math_private.h, but if we relax this restriction (and fix some portability sloppiness) we can use it directly and not have to expose all of math_private.h to the testsuite. * sysdeps/generic/math_private.h: Use __BIG_ENDIAN and __LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN. * sysdeps/generic/math_ldbl.h * sysdeps/ia64/fpu/math_ldbl.h * sysdeps/ieee754/ldbl-128/math_ldbl.h * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h * sysdeps/ieee754/ldbl-96/math_ldbl.h * sysdeps/powerpc/fpu/math_ldbl.h * sysdeps/x86_64/fpu/math_ldbl.h: Allow direct inclusion.

Add copyright notices. * sysdeps/ieee754/ldbl-128ibm/math_ldbl.h (ldbl_canonicalize_int): Don't use EXTRACT_WORDS64. * sysdeps/ieee754/ldbl-96/test-canonical-ldbl-96.c * sysdeps/ieee754/ldbl-96/test-totalorderl-ldbl-96.c * sysdeps/ieee754/ldbl-128ibm/test-canonical-ldbl-128ibm.c * sysdeps/ieee754/ldbl-128ibm/test-totalorderl-ldbl-128ibm.c: Include math_ldbl.h, not math_private.h.
2017-02-25Split DIAG_* macros to new header libc-diag.h.Zack Weinberg
Quite a few tests include libc-internal.h just for the DIAG_* macros. Split those macros to their own file, which can be included safely in _ISOMAC mode. I also moved ignore_value, since it seems logically related, even though I didn't notice any tests needing it. Also add -Wnonnull suppressions to two tests that _should_ have them, but the error is masked when compiling against internal headers. * include/libc-diag.h: New file. Define ignore_value, DIAG_PUSH_NEEDS_COMMENT, DIAG_POP_NEEDS_COMMENT, DIAG_IGNORE_NEEDS_COMMENT, and DIAG_IGNORE_Os_NEEDS_COMMENT here. * include/libc-internal.h: Definitions of above macros moved from here. Include libc-diag.h. Add copyright notice. * malloc/tst-malloc.c, malloc/tst-memcheck.c, malloc/tst-realloc.c * misc/tst-error1.c, posix/tst-dir.c, stdio-common/bug21.c * stdio-common/scanf14.c, stdio-common/scanf4.c, stdio-common/scanf7.c * stdio-common/test-vfprintf.c, stdio-common/tst-printf.c * stdio-common/tst-printfsz.c, stdio-common/tst-sprintf.c * stdio-common/tst-unlockedio.c, stdio-common/tstdiomisc.c * stdlib/bug-getcontext.c, string/tester.c, string/tst-endian.c * time/tst-strptime2.c, wcsmbs/tst-wcstof.c: Include libc-diag.h instead of libc-internal.h. * stdlib/tst-environ.c: Include libc-diag.h. Suppress -Wnonnull for call to unsetenv (NULL). * nptl/tst-mutex1.c: Include libc-diag.h. Suppress -Wnonnull for call to pthread_mutexattr_destroy (NULL).
2017-02-25Clean up conditionals for declaration of gets.Zack Weinberg
gets has the dubious honor of being the only C89 library feature that has been completely removed from the current C and C++ standards. glibc follows suit by not declaring it in _GNU_SOURCE mode either, but it remains present in older compatibility modes. Internally, two test cases need to see stdio.h make the declaration, but all our internal code is of course compiled under _GNU_SOURCE. This is currently kludged by duplicating the gets declaration, fortify wrapper and all, in include/stdio.h. Also, the conditional in the public headers for deciding when to declare gets is complicated and repeated in two places. This patch adds a new macro to features.h that encapsulates the complicated rule for when to declare gets. stdio.h and bits/stdio2.h then simply test __GLIBC_USE (DEPRECATED_GETS), and instead of having a duplicate gets declaration in include/stdio.h, debug/tst-chk1.c and stdio-common/tst-gets.c can force gets to be declared. * include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro. * libio/stdio.h, libio/bits/stdio2.h: Condition gets on __GLIBC_USE (DEPRECATED_GETS). Update comments to indicate gets was removed from C++ in C++14. * include/stdio.h: Remove redundant declaration of gets. * debug/tst-chk1.c, stdio-common/tst-gets.c: Force gets to be declared, since we are testing it. * stdio-common/Makefile (tst-gets.c): Compile with -Wno-deprecated-declarations. * debug/Makefile (tst-chk1.c, tst-chk2.c, tst-chk3.c, tst-chk4.cc) (tst-chk5.cc, tst-chk6.cc, tst-lfschk1.c, tst-lfschk2.c) (tst-lfschk3.c, tst-lfschk4.cc, tst-lfschk5.cc, tst-lfschk6.cc): Compile with -Wno-deprecated-declarations.

2017-02-24Get rid of duplicate const declaration specifier warning in tst-resolv-qtypes.c.Stefan Liebler
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in: tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier] static const const char *domain = "www.example.com"; This patch removes the duplicate const and makes domain a const pointer to const char literal. ChangeLog: * resolv/tst-resolv-qtypes.c (domain): Change type to const pointer to const char.
2017-02-24Run libm tests separately for each function.Joseph Myers
At present, libm tests for each function get built into a single executable (for each floating point type, for each of normal / inline / finite-math-only functions, plus vector variants) and run together, resulting in a single PASS or FAIL (for each of those nine variants plus vector variants). Building this executable involves reading over 50 MB of libm-test-*.c sources. This patch arranges for tests of each function to be run separately from the makefiles instead. There are 121 functions being tested for each (type, variant pair) (actually 126, but run as 121 from the Makefile because each of the pairs (exp10, pow10), (isfinite, finite), (lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of test results and so is run together), so 1089 separate tests run from the Makefile, plus 48 vector tests on x86_64 (six functions for eight vector variants). Each test only involves a libm-test-<func>.c file of no more than about 4 MB, rather than all such files taking about 50 MB. With tests run separately, test summaries will indicate which functions actually have problems (of course, those problems may just be out-of-date libm-test-ulps files if the file hasn't been updated for the architecture in question recently). All the .c files for the 1089+48 tests are generated automatically from the Makefiles. Various checked-in boilerplate .c files are removed as no longer needed. CFLAGS definitions for the different kinds of tests are generated using makefile iterators to apply target-specific variable settings. libm-have-vector-test.h is no longer needed; the list of functions to test for each vector type is now in the sysdeps Makefile. This should reduce the amount of boilerplate needed for float128 testing support; test-float128.h will still be needed, but not various .c files or Makefile CFLAGS definitions. The logic for creating dependencies on libm-test-support-*.o files should also render <https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html> unnecessary.

2017-02-23Add new templates for IEEE wrappersGabriel F. T. Gomes
Several wrappers for IEEE functions use _LIB_VERSION / matherr / __kernel_standard functionality, which we want to obsolete. New wrappers, such as for float128, must not use this functionality.

2017-02-22Add TFD_TIMER_CANCEL_ON_SET to sys/timerfd.h.Joseph Myers
In Linux 4.10, timerfd constants moved to a new uapi header, which showed up that glibc's sys/timerfd.h is missing the old flag TFD_TIMER_CANCEL_ON_SET. This patch adds that flag to glibc's header. Tested for x86_64. * sysdeps/unix/sysv/linux/sys/timerfd.h (TFD_TIMER_CANCEL_ON_SET): New enum constant and macro.

This patch removes some libm-test-support.h macros for exceptions that are no longer used. EXCEPTIONS_OK has been unused for some time. The macros for underflow exceptions with some types only were used when the results for complex inverse trig and hyperbolic functions were manually maintained, but are no longer needed now the auto-libm-test machinery is used to determine the correct result and exceptions for every floating-point format and rounding mode.

2017-02-17Rework -fno-omit-frame-pointer support on i386Adhemerval Zanella
Commit 6b1df8b27f fixed the -OS build issue on i386 (BZ#20729) by expliciting disabling frame pointer (-fomit-frame-pointer) on the faulty objects. Although it does fix the issue, it is a subpar workaround that adds complexity in build process (a rule for each object to add the required compiler option and pontentially more rules for objects that call {INLINE,INTERNAL}_SYSCALL) and does not allow the implementations to get all the possible debug/calltrack information possible (used mainly in debuggers and performance measurement tools). This patch fixes it by adding an explicit configure check to see if -fno-omit-frame-pointer is set and to act accordingly (set or not OPTIMIZE_FOR_GCC_5). The make rules is simplified and only one is required: to add libc-do-syscall on loader due mmap (which will be empty anyway for default build with -fomit-frame-pointer). Checked on i386-linux-gnu with GCC 6.2.1 with CFLAGS sets as '-Os', '-O2 -fno-omit-frame-pointer', and '-O2 -fomit-frame-pointer'. For '-Os' the testsuite issues described by BZ#19463 and BZ#15105 still applied. It fixes BZ #21029, although it is marked as duplicated of #20729 (I reopened to track this cleanup).

This patch moves tests of catan and catanh with finite inputs (other than the divide-by-zero cases producing an exact infinity) to using the auto-libm-test machinery. Each of auto-libm-test-out-catan and auto-libm-test-out-catanh takes about three seconds to generate on my system (so in fact it wasn't necessary after all to defer the move to auto-libm-test-* until the output files were split up by function).

2017-02-16Move bits/types.h into posix/bits.Zack Weinberg
bits/types.h has no sysdeps variants, so it should be in the subdirectory that installs it (namely, posix). * bits/types.h: Move to posix/bits. * include/bits/types.h: New wrapper.
2017-02-15Remove the str(n)cmp inlines from string/bits/string2.h. The strncmpWilco Dijkstra
optimization seems unlikely to ever be useful, but if it occurs in real code it should be added to GCC. Expanding strcmp of small strings does appear useful (benchmarking shows it is 2-3x faster), so this would be useful to implement in GCC (PR 78809). * string/bits/string2.h (strcmp): Remove define.

2017-02-15The internal header include/string.h does not work in C++: it causes link errorsWilco Dijkstra
in several C++ debug tests when any of the functions it declares are called. The best option would be to not use internal headers for tests (unless explicitly needed). Add guards so that it is safe to use include/string.h from C++. * include/string.h: Add __cplusplus check.
2017-02-15Fix y0 and y1 exception handling for zero input [BZ #21134]Gabriel F. T. Gomes
The Bessel functions of the second type (Yn) should raise the "divide by zero" exception when input is zero (both positive and negative). Current code gives the right output, but fails to set the exception. This error is exposed for float, double, and long double when linking with -lieee.

2017-02-15Move most libmvec test contents from .c to .h files.Joseph Myers
The libmvec tests put substantive, architecture-specific contents in .c files such as test-double-vlen4.c, so making those files architecture-specific and causing issues for generating such files automatically when splitting up tests by function. This patch moves all the substantive contents to .h files, so the .c files only include the .h file and then libm-test.c. This allows for automatic generation of per-function .c files in future. The .h files in turn #include or #include_next the architecture-independent file and add the architecture-specific definitions to that. (Splitting by function should in fact allow the TEST_VECTOR_* macros to be replaced by sysdeps makefile information on which functions to test in each case, removing the need for gen-libm-have-vector-test.sh as well as removing the need for some of the architecture-specific headers.)

2017-02-14Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.Joseph Myers
libmvec tests involve calling INIT_ARCH_EXT during initialization then CHECK_ARCH_EXT before testing each function to see if the processor being used for testing supports the required instruction set extensions. After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT call is in libm-test-support.c, built only once per floating-point type. Now, in fact all definitions of this macro are empty, but given that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are conditional on REQUIRE_* macros defined in particular vector tests, it seems more correct for the INIT_ARCH_EXT call to go instead in libm-test-driver.c which gets built separately with those REQUIRE_* macros properly defined. This patch moves the call there. Tested for x86_64 and x86. * math/libm-test-support.h: Do not include <math-tests-arch.h> here. * math/libm-test-support.c (libm_test_init): Do not call INIT_ARCH_EXT here. * math/libm-test-driver.c: Include <math-tests-arch.h>.

2017-02-12ldbl-128: Fix y0 and y1 for -Inf input [BZ #21130]Gabriel F. T. Gomes
The Bessel functions of the second type (Yn) are not defined for negative input and should return NAN with the "invalid" exception raised, in these cases. However, current code checks for infinity and return zero, regardless of the sign. This error is exposed for long double when linking with -lieee. Without this flag, the error is not exposed, because the wrappers for these functions, which use __kernel_standard functionality, return the correct value. Tested for powerpc64le.

2017-02-10GLIBC uses strchr (s, '\0') as an idiom to find the end of a string.Wilco Dijkstra
This is transformed into rawmemchr by the bits/string2.h header. However this is generally slower than strlen on most targets, even when an optimized rawmemchr implementation exists. Since GCC7 optimizes strchr (s, '\0') to strlen (s) + s, the GLIBC headers should not transform this to rawmemchr. As GCC recognizes strchr as a builtin, defining strchr as the builtin is not useful. * string/bits/string2.h (strchr): Remove define.

2017-02-09Move more csin, csinh tests to auto-libm-test-in.Joseph Myers
When I moved tests of csin and csinh to auto-libm-test-in, I didn't move a few tests for which gen-auto-libm-tests was very slow because of MPC slowness on certain inputs. Now that auto-libm-test-out has been split up, such slowness only affects regenerating the test expectations for the individual functions in question, rather than any addition of tests for any function to auto-libm-test-in. Thus, I no longer consider it a problem to have these inputs in auto-libm-test-in, and this patch moves them there. This results in test generation for csin and csinh taking 5m43s (for each of csin and csinh) on my system, while other functions are unaffected. I expect the test generation to be much faster in MPC 1.1 (the relevant performance improvements went in MPC mainline in Dec 2013, but there hasn't been a release from mainline since then). Tested for x86_64 and x86. * math/auto-libm-test-in: Add more tests of csin and csinh. * math/auto-libm-test-out-csin: Regenerated. * math/auto-libm-test-out-csinh: Likewise. * math/libm-test-csin.inc (csin_test_data): Remove tests moved to auto-libm-test-in. * math/libm-test-csinh.inc (csinh_test_data): Likewise.
2017-02-09Merge libm-compat-calls-auto and libm-compat-callsGabriel F. T. Gomes
Both libm-compat-calls and libm-compat-calls-auto list the functions that must be built for the types float, double, and long double, but not for other floating-point types that get added to libm. Besides that, the use of libm-compat-calls-ldouble-yes to select if w_lgamma_compatl and k_standardl should be built for long-double (in libm-compat-calls) has the same effect of the use of type-foreach (in libm-compat-calls-auto). This patch merges the contents of libm-compat-calls into libm-compat-calls-auto, then renames the latter to libm-compat-calls. Tested for powerpc64le, s390, and x86_64. * math/Makefile (libm-compat-calls-ldouble-yes): Merge into libm-compat-calls-auto. (libm-compat-calls): Likewise. (libm-compat-calls-auto): Rename to libm-compat-calls and add w_lgamma_compatF and k_standardF (merged from the items above).

2017-02-09Move -U__LIBC_INTERNAL_MATH_INLINES to test-math-inline.h.Joseph Myers
The libm tests of inline functions undefine __NO_MATH_INLINES (from math-CPPFLAGS) in test-math-inline.h, but __LIBC_INTERNAL_MATH_INLINES via -U options in the makefile. This is an odd inconsistency between the handling of the two macros. It also depends on the ordering (in compilation commands) of the various variables providing compiler options (which I think is why it's using CPPFLAGS-*.c instead of CFLAGS-*.c). This patch moves the undefine to test-math-inline.h, so improving consistency and eliminating the dependency on the order in which variables go in the compilation commands. The CPPFLAGS-*.c variables are renamed to CFLAGS-*.c, matching those for the non-inline libm function tests. By moving the -U option to the header file, this should ensure that ordering issues don't arise with a subsequent move of the options to these tests to target-specific CFLAGS += ... variable settings (for when tests for each function are build separately and so compilation options need setting for many more makefile targets, for which target-specific variable settings seem to be the most convenient form to generate with iterators). Tested for x86_64. * math/test-math-inline.h (__LIBC_INTERNAL_MATH_INLINES): Undefine macro. * math/Makefile (CPPFLAGS-test-ifloat.c): Rename to ... (CFLAGS-test-ifloat.c): ... this.

2017-02-08Build most libm-test support code once per type.Joseph Myers
libm-test-driver.c contains various functions used in the course of libm testing, which are built as part of each test using this machinery. Currently, these functions get built for three tests for each type (e.g. test-float, test-ifloat, test-float-finite), plus the vector function tests. All these tests are huge and thus slow to build; the output of gen-libm-test.pl totals around 40 MB across all functions. To make the individual tests built from the Makefile smaller, it makes sense to split these tests up so the tests for each function are built separately (thus, three tests for each (function, type) pair, plus vector tests built only for functions that actually have vector versions). This improves parallelism and means that if tests fail, the summary of failed tests makes it more obvious where the problem might be without needing to look in the .out files to see which functions' tests failed (though architecture maintainers still need to keep libm-test-ulps up to date to avoid spurious failures of little interest). Simply including libm-test-driver.c as-is in such individual-function tests does not work because of unused static check_* functions (those functions only being used for the types of the outputs of the function under test). It also means the common code gets built over 1000 times instead of nine (plus vector tests). To avoid that issue, this patch splits out the bulk of the libm-test-driver.c code into a separate file libm-test-support.c (with a few functions made non-static). That separate file is built only once for each floating-point type (so at present three times, or twice on architectures with long double = double). Definitions needed in both libm-test-support.c and libm-test-driver.c go in libm-test-support.h (it's possible some of those are in fact only needed in one of the two files). libm-test-driver.c keeps definitions of a limited number of variables used to configure how libm-test-support.c behaves, various macros and structures needed by individual-function tests, and the main function. This move is also consistent in spirit with the move away from test-skeleton.c having all the test support code, to a small support/test-driver.c included in individual tests with most of the code built separately.
