* Fix test failure with -DNDEBUG.Carlos O'Donell2018-08-301-0/+5
| | | | | | | | | | | | The elf/tst-dlopen-aout.c test uses asserts to verify properties of the test execution. Instead of using assert it should use xpthread_create and xpthread_join to catch errors starting the threads and fail the test. This shows up in Fedora 28 when building for i686-pc-linux-gnu and using gcc 8.1.1. Tested on i686, and fixes a check failure with -DNDEBUG. Signed-off-by: Carlos O'Donell <carlos@redhat.com>
* reallocarray: Declare under _DEFAULT_SOURCEFlorian Weimer2018-08-301-0/+4
| | | | | | Initially, this function was restricted to _GNU_SOURCE, but experience shows that compatibility with existing build systems is improved if we declare it under _DEFAULT_SOURCE as well.
* Test stdlib/test-bz22786 exits now with unsupported if malloc fails.Stefan Liebler2018-08-301-0/+5
| | | | | | | | | | | | | | | | | | The test tries to allocate more than 2^31 bytes which will always fail on s390 as it has maximum 2^31bit of memory. Before commit 6c3a8a9d868a8deddf0d6dcc785b6d120de90523, this test returned unsupported if malloc fails. This patch re enables this behaviour. Furthermore support_delete_temp_files() failed to remove the temp directory in this case as it is not empty due to the created symlink. Thus the creation of the symlink is moved behind malloc. Reviewed-by: Carlos O'Donell <carlos@redhat.com> ChangeLog: * stdlib/test-bz22786.c (do_test): Return EXIT_UNSUPPORTED if malloc fails.
* Make gen-libm-test.py treat plus_oflow and minus_oflow as non-finite.Joseph Myers2018-08-291-0/+5
| | | | | | | | | | | | | | | | | | | | | When converting gen-libm-test to Python, in one place I noted a bug in the old Perl version that I preserved in the Python version so that the generated output files were the same with both versions, as such comparisons help give confidence in the correctness of such a rewrite of a script. Now that the conversion has been done, this patch fixes that bug, by arranging for tests with plus_oflow or minus_oflow results (manually written tests in libm-test-*.inc that have overflowing results that thus depend on the rounding mode) to be properly treated as having non-finite results, and thus not run for the __FINITE_MATH_ONLY__ tests. (As the affected tests in fact did pass for __FINITE_MATH_ONLY__ testing, this is just a matter of logical correctness in the choice of which tests run for that case, rather than fixing any actual test failures.) Tested for x86_64. * math/gen-libm-test.py (gen_test_args_res): Also treat plus_oflow and minus_oflow as non-finite.
* Split fenv_private.h out of math_private.h more consistently.Joseph Myers2018-08-281-0/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some architectures, the parts of math_private.h relating to the floating-point environment are in a separate file fenv_private.h included from math_private.h. As this is purely an architecture-specific convention used by several architectures, however, all such architectures still need their own math_private.h, even if it has nothing to do beyond #include <fenv_private.h> and peculiarity of including the i386 file directly instead of having a shared file in sysdeps/x86. This patch makes the fenv_private.h name an architecture-independent convention in glibc. The include of fenv_private.h from math_private.h becomes architecture-independent (until callers are updated to include fenv_private.h directly so the include from math_private.h is no longer needed). Some architecture math_private.h headers are removed if no longer needed, or renamed to fenv_private.h if all they define belongs in that header; architecture fenv_private.h headers now do require #include_next <fenv_private.h>. The i386 fenv_private.h file moves to sysdeps/x86/fpu/ to reflect how it is actually shared with x86_64. The generic math_private.h gets a new include of <stdbool.h>, as needed for bool in some prototypes in that header (previously that was indirectly included via include/fenv.h, which now only gets included too late in math_private.h, after those prototypes). Tested for x86_64 and x86, and tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/aarch64/fpu/fenv_private.h: New file.

* Move EXCEPTION_TESTS_* out of math-tests.hJoseph Myers2018-08-231-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the EXCEPTION_TESTS_* macros for individual types out to their own sysdeps header. As with ROUNDING_TESTS_*, there is no need to define these macros if FE_ALL_EXCEPT == 0 and the individual exception macros are undefined; thus, math-tests-exceptions.h headers are only needed for soft-float ARM and RISC-V, while the other cases that defined these macros do not need to do so (and the associated math-tests.h headers are thus removed without needing replacement by math-tests-exceptions.h headers).

| | | | | | | | | | | | | | | | Speedup tanf range reduction by using the new sincosf range reduction algorithm.

| | | | | | | | | | | | | | | | | | | | | | | | | | This patch completes the move of ROUNDING_TESTS_* macros to typo-proof conventions by stopping redefining them in test-*-vlen*.h.

* Move ROUNDING_TESTS_* out of math-tests.h.Joseph Myers2018-08-221-0/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing moving macros out of math-tests.h to smaller headers following typo-proof conventions instead of using #ifndef, this patch moves the ROUNDING_TESTS_* macros for individual types out to their own sysdeps header. In the soft-float case where FE_TONEAREST is the only rounding mode macro defined, there is no need to define ROUNDING_TESTS_*; it is only necessary when rounding modes macros are defined that may not be supported at runtime. Thus, the ROUNDING_TESTS_* definitions for some configurations are just removed, not moved to new math-tests-rounding.h headers; the only architectures needing math-tests-rounding.h are those where the macros are defined in bits/fenv.h because of the possibility of a soft-float compilation using a hard-float glibc with the same ABI (i.e., ARM and RISC-V). The test-*-vlen*.h headers, by using #undef, do not yet follow typo-proof conventions (but they no longer implicitly rely on being included before math-tests.h, and this area can always be cleaned up further in future).

* Add PF_XDP, AF_XDP and SOL_XDP from Linux 4.18 to bits/socket.h.Tobias Klauser2018-08-211-0/+7

* Update netinet/tcp.h from Linux 4.18.Joseph Myers2018-08-211-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds constants from netinet/tcp.h in Linux 4.18, and an associated struct tcp_zerocopy_receive, to sysdeps/gnu/netinet/tcp.h. The new TCP_REPAIR_* constants seemed sufficiently related to those already present to include them. Note that this patch does not include additions to struct tcp_info; there are many other elements in this structure in the Linux kernel that are not included in the glibc version (which was last extended in 2007, it seems). Such additions to the end of the structure may be OK with the expected way it is used (size passed explicitly to the kernel with getsockopt), but in principle any change to the size of a type provided by glibc is an ABI change for external applications / libraries using that type in their ABIs, and has the associated risks of such a change. Tested for x86_64. * sysdeps/gnu/netinet/tcp.h (TCP_ZEROCOPY_RECEIVE): New macro. (TCP_INQ): Likewise. (TCP_CM_INQ): Likewise. (TCP_REPAIR_ON): Likewise. (TCP_REPAIR_OFF): Likewise. (TCP_REPAIR_OFF_NO_WP): Likewise. (struct tcp_zerocopy_receive): New type.

| | | | | | | | | | | | | This patch updates struct signalfd_siginfo in sys/signalfd.h with new members from Linux 4.18 (plus ssi_addr_lsb, added to the kernel in 2.6.37 without being added to sys/signalfd.h at that time). The __pad2 member name follows the kernel and the existing __pad name. Tested for x86_64. * sysdeps/unix/sysv/linux/sys/signalfd.h (struct signalfd_siginfo): Add ssi_addr_lsb, ssi_syscall, ssi_call_addr and ssi_arch members.

| | | | | Based on results on a s390x 2964 machine, with -march=z196 and -mtune=zEC12, and separately with -march=z13 and -mtune=z14.
* Add --with-nonshared-cflags option to configureFlorian Weimer2018-08-171-0/+10
|
* Makeconfig (ASFLAGS): Always append required assembler flagsFlorian Weimer2018-08-171-0/+4
| | | | | Otherwise, it is impossible to set ASFLAGS differently from CFLAGS without also overriding essential flags such as -Wa,--noexecstack.
* Fix attribution of previous change in ChangeLogFlorian Weimer2018-08-171-1/+1

* malloc: Mitigate null-byte overflow attacksMoritz Eckert2018-08-161-0/+5
| | | | | * malloc/malloc.c (_int_free): Check for corrupt prev_size vs size. (malloc_consolidate): Likewise.
* malloc: Verify size of top chunk.Pochang Chen2018-08-161-0/+4
| | | | | | | | | | | | The House of Force is a well-known technique to exploit heap overflow. In essence, this exploit takes three steps: 1. Overwrite the size of top chunk with very large value (e.g. -1). 2. Request x bytes from top chunk. As the size of top chunk is corrupted, x can be arbitrarily large and top chunk will still be offset by x. 3. The next allocation from top chunk will thus be controllable. If we verify the size of top chunk at step 2, we can stop such attack.
* Reallocate buffers for every run in strlenSiddhesh Poyarekar2018-08-161-0/+3
| | | | Try and avoid influencing performance of neighbouring functions.
* Print strlen benchmark output in jsonSiddhesh Poyarekar2018-08-161-0/+4
| | | | Allow reading the benchmark using the compare_strings.py script.
* powerpc: Rearrange little endian specific filesRajalakshmi Srinivasaraghavan2018-08-161-0/+22
| | | | | | This patch moves little endian specific POWER9 optimization files to sysdeps/powerpc/powerpc64/le and creates POWER9 ifunc functions only for little endian.
* [aarch64] Add an ASIMD variant of strlen for falkorSiddhesh Poyarekar2018-08-151-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This variant of strlen uses vector loads and operations to reduce the size of the code and also eliminate the non-ascii fallback. This works very well for falkor because of its two vector units and efficient vector ops. In the best case it reduces latency of cases in bench-strlen by 48%, with gains throughout the benchmark. strlen-walk also sees uniform gains in the 5%-15% range. Overall the routine appears to work better than the stock one for falkor regardless of the benchmark, length of string or cache state. The same cannot be said of a53 and a72 though. a53 performance was greatly reduced and for a72 it was a bit of a mixed bag, slightly on the negative side but I reckon it might be fast in some situations. * sysdeps/aarch64/strlen.S (__strlen): Rename to STRLEN. [!STRLEN](STRLEN): Set to __strlen. * sysdeps/aarch64/multiarch/strlen.c: New file. * sysdeps/aarch64/multiarch/strlen_generic.S: Likewise. * sysdeps/aarch64/multiarch/strlen_asimd.S: Likewise. * sysdeps/aarch64/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add strlen. * sysdeps/aarch64/multiarch/Makefile (sysdep_routines): Add strlen_generic and strlen_asimd.

* Use generic sinf/cosf in lgammaf_rWilco Dijkstra2018-08-151-0/+6
| | | | | | | | | | | | | | The internal functions __kernel_sinf and __kernel_cosf are used only by lgammaf_r. Removing the internal functions and using the generic sinf and cosf is better overall. Benchmarking on Cortex-A72 shows the generic sinf and cosf are 1.4x and 2.3x faster in the range |x| < PI/4, and 0.66x and 1.1x for |x| < PI/2, so it should make lgammaf_r faster on average. GLIBC regression tests pass on AArch64. * sysdeps/ieee754/flt-32/e_lgammaf_r.c (sin_pif): Use __sinf/__cosf. * sysdeps/ieee754/flt-32/k_cosf.c (__kernel_cosf): Remove all code. * sysdeps/ieee754/flt-32/k_sinf.c (__kernel_sinf): Likewise.
* Fix spaces in x86_64 ULP fileWilco Dijkstra2018-08-151-0/+4
| | | | | | | | Fix a few missing spaces, it's now identical to the regenerated version. Passes GLIBC tests on x64. * sysdeps/x86_64/fpu/libm-test-ulps: Regenerate to fix spaces.
* error, warn, warnx: Use __fxprintf for wide printing [BZ #23519]Florian Weimer2018-08-141-0/+12
