* Increase timeout of nss/tst-nss-files-hosts-multiHEADmasterSzabolcs Nagy2018-10-091-0/+4
| | | | | | | | | | | | | | | | | | | Increase timeout from the default 20s to 40s. This test makes close to 2 million syscalls with distribution: 1180249 connect 297952 getsockname 144040 lseek 143734 read 14466 close ... connect can be slow, so the default timeout was not enough on slow systems.

* mktime fix for Gnulib + coreutilsPaul Eggert2018-10-081-0/+12
| | | | | | | | | | | [BZ#23745] This fix affects only Gnulib. Problem discovered when mktime.c was used as part of Gnulib in bleeding-edge Coreutils. * time/mktime.c: (my_tzset) [!_LIBC && !NEED_MKTIME_WORKING && !NEED_MKTIME_WINDOWS]: Do not define since it is not used. Defining an unused static function prompts a warning from GCC when Coreutils is configured with --enable-gcc-warnings.

* Use bits/mman-linux.h for hppa.Joseph Myers2018-10-041-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | hppa currently has a bits/mman.h that does not include bits/mman-linux.h, unlike all other architectures using the Linux kernel. This sort of variation between architectures is generally unhelpful when making global changes for new constants added to new Linux kernel releases. This patch changes hppa to use bits/mman-linux.h, overriding constants with different values as necessary (including with #undef after bits/mman.h inclusion when needed, as already done for alpha). While there could possibly be further improvements through e.g. splitting more sets of definitions into separate bits/ headers, I think this is still an improvement on the current state. diffstat shows 27 lines added, 51 deleted (and some of that is actually existing lines moving to a different place in the file). Tested with build-many-glibcs.py for hppa-linux-gnu. * sysdeps/unix/sysv/linux/hppa/bits/mman.h: Include <bits/mman-linux.h>. (PROT_READ): Don't define here. (PROT_WRITE): Likewise.

* Fix libnldbl_nonshared.a references to internal libm symbols (bug 23735).Joseph Myers2018-10-041-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The redirection of built-in functions such as sqrt in include/math.h applies when the wrappers for those functions in libnldbl_nonshared.a are built, resulting in references to internal names such as __ieee754_sqrt that aren't actually exported from the shared libm. (This applies for sqrt in 2.28, also for the round-to-integer functions in current master because of my changes there.) This patch arranges for NO_MATH_REDIRECT to be used for all the affected functions, and adds a test for those functions in libnldbl_nonshared.a. (We could of course choose to obsolete libnldbl_nonshared.a and require that people building with -mlong-double-64 either include the relevant headers and have a compiler supporting asm redirection, or have some other means of achieving that redirection at compile time if not including those headers. But while we have libnldbl_nonshared.a, it seems appropriate to fix such bugs in it.) Tested for powerpc, and with build-many-glibcs.py. [BZ #23735] * sysdeps/ieee754/ldbl-opt/nldbl-compat.h (NO_MATH_REDIRECT): Define. * sysdeps/ieee754/ldbl-opt/test-nldbl-redirect.c: New file. * sysdeps/ieee754/ldbl-opt/Makefile [$(subdir) = math] (tests): Add test-nldbl-redirect.

* Adjust name of ld.so in test-container.c.Stefan Liebler2018-10-041-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | The test-container.c file assumes that ld.so is always named something like /elf/ld-linux-*. But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390. There are other architectures like power or mips with similar names. This patch introduces the new global variable support_objdir_elf_ldso which contains the absolute path to the runtime linker used by the testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2. The check in test-container.c is now comparing against this path. Without this patch, test-container.c is searching invalid files / directories and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script. Then the test tst-nss-test3 fails!

* kl_GL: Fix spelling of Sunday, should be "sapaat" (bug 20209).Rafal Luzynski2018-10-021-0/+8

* Add more fma tests.Joseph Myers2018-10-021-0/+4
| | | | | | | | | | | | | | | | | | In my review <https://sourceware.org/ml/libc-alpha/2018-06/msg00375.html> of a patch for bug 23584, I expressed concern that the proposed changes didn't deal with certain cases similar to the ones in the bug but where test coverage was missing. This patch adds such tests of fma (Inf, finite, finite) and fma (finite, Inf, finite) to libm-test-fma.inc. It does *not* do anything to fix the bug, simply adds test coverage to provide stronger evidence of whether any proposed revised fix does address the cases I was concerned with. Tested for x86_64 and x86. * math/libm-test-fma.inc (fma_test_data): Add more tests.

* libio: Flush stream at freopen (BZ#21037)Adhemerval Zanella2018-10-021-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | As POSIX states [1] a freopen call should first flush the stream as if by a call fflush. C99 (n1256) and C11 (n1570) only states the function should first close any file associated with the specific stream. Although current implementation only follow C specification, current BSD and other libc implementation (musl) are in sync with POSIX and fflush the stream. This patch change freopen{64} to fflush the stream before actually reopening it (or returning if the stream does not support reopen). It also changes the Linux implementation to avoid a dynamic allocation on 'fd_to_filename'. Checked on x86_64-linux-gnu.

* Remove unnecessary math_private.h includes.Joseph Myers2018-09-281-0/+90

Furthermore, since the optimized inlines of various functions have been moved to include/fenv.h or replaced by use of function names GCC inlines automatically, a missing math_private.h include where one is appropriate will reliably cause a build failure rather than possibly causing code to be less well optimized while still building successfully. Thus, this patch removes includes of math_private.h that are now unnecessary. In the case of two RISC-V files, the include is replaced by one of stdbool.h because the files in question were relying on math_private.h to get a definition of bool.

* Fix misreported errno on preadv2/pwritev2 (BZ#23579)Adhemerval Zanella2018-09-281-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The fallback code of Linux wrapper for preadv2/pwritev2 executes regardless of the errno code for preadv2, instead of the case where the syscall is not supported. This fixes it by calling the fallback code iff errno is ENOSYS. The patch also adds tests for both invalid file descriptor and invalid iov_len and vector count. The only discrepancy between preadv2 and fallback code regarding error reporting is when an invalid flags are used. The fallback code bails out earlier with ENOTSUP instead of EINVAL/EBADF when the syscall is used. Checked on x86_64-linux-gnu on a 4.4.0 and 4.15.0 kernel.

That common set is moved to bits/mman-map-flags-generic.h, which is included by bits/mman.h, to allow architectures to use that common set even if they also have architecture-specific additions to it. As well as the generic bits/mman.h, the versions for x86 and ia64 are also then made to include bits/mman-map-flags-generic.h, so while they still need architecture-specific bits/mman.h (for MAP_32BIT and MAP_GROWSUP respectively), they do not need to duplicate the generic flag definitions in there.

* Fix ifunc support with DT_TEXTREL segments (BZ#20480)Adhemerval Zanella2018-09-251-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, DT_TEXTREL is incompatible with IFUNC. When DT_TEXTREL or DF_TEXTREL is seen, the dynamic linker calls __mprotect on the segments with PROT_READ|PROT_WRITE before applying dynamic relocations. It leads to segfault when performing IFUNC resolution (which requires PROT_EXEC as well for the IFUNC resolver). This patch makes it call __mprotect with extra PROT_WRITE bit, which will keep the PROT_EXEC bit if exists, and thus fixes the segfault. FreeBSD rtld libexec/rtld-elf/rtld.c (reloc_textrel_prot) does the same.

| | | | | | | | | | | | | | | | | | | | | | | | | This patch completes the process of unifying sys/procfs.h headers for architectures using the Linux kernel by making alpha use the generic version. That was previously deferred because alpha has different definitions of prgregset_t and prfpregset_t from other architectures, so changing to the common definitions would change C++ name mangling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues the process of unifying sys/procfs.h headers for architectures using the Linux kernel. A bits/procfs-id.h header is added to define __pr_uid_t and __pr_gid_t for the types of pr_uid and pr_gid; the default version of this header uses unsigned int. On some architectures, sys/procfs.h has copies of 32-bit structures for 64-bit builds; those move into a bits/procfs-extra.h header (they can't go in bits/procfs.h because they have to come *after* other declarations from sys/procfs.h). Given appropriate versions of these headers, six more architectures can then move to providing only bits/procfs*.h without duplicating the rest of the contents of sys/procfs.h. Only alpha needs a further bits/ header to be added before it can stop having its own sys/procfs.h.

* Unify some sys/procfs.h headers.Joseph Myers2018-09-251-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As per recent discussions, this patch unifies some of the sys/procfs.h headers for architectures using the Linux kernel, producing a generic version that can hopefully be used by all new architectures as well. The new generic version is based on the AArch64 one. The register definitions, the only part that generally needs to vary by architecture, go in a new bits/procfs.h header (which each architecture using the generic version needs to provide); that header also has any #includes that were in the architecture-specific sys/procfs.h, where those includes went beyond the generic set. The generic version is used for eight architectures where the generic definitions were the same as the architecture-specific ones. (Some of those architectures had #if 0 fields, now removed; some defined types or fields using different type names which were typedefs for the same underlying types.) Six of the remaining architectures with their own sys/procfs.h use unsigned short for pr_uid / pr_gid in some cases; moving those to the generic header will require a bits/ header to define a typedef for the type of those fields. In the case of alpha, the generic sys/procfs.h uses elf_gregset_t (= unsigned long int[33]) to define prgregset_t and elf_fpregset_t (= double[32]) to define prfpregset_t, but the alpha version uses gregset_t (= long int[33]) and fpregset_t (= long int[32]), so avoiding unnecessarily changing the underlying types (and thus C++ name mangling) again means a bits/ header will need to be able to define a different choice for those typedefs. bits/procfs.h is included outside the __BEGIN_DECLS / __END_DECLS pair (whereas the definitions it contains were previously inside that pair in various sys/procfs.h headers), because it sometimes includes other headers and putting those other #includes inside that pair seems risky. Because none of the declarations in bits/procfs.h are of functions or variables or involve function types, I don't think it makes any difference whether they are inside or outside an extern "C" context. Tested with build-many-glibcs.py (again, that does not provide much validation for the correctness of this patch). * sysdeps/unix/sysv/linux/sys/procfs.h: Replace with file based on AArch64 version.

In addition, the extern declaration of the variable __gconv_nmodules refers to a variable that does not exist any more. Considering this, these symbols do not need to be exposed via a header file.

* powerpc: Only enable TLE with PPC_FEATURE2_HTM_NOSCAdhemerval Zanella2018-09-211-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux from 3.9 through 4.2 does not abort HTM transaction on syscalls, instead it suspend and resume it when leaving the kernel. The side-effects of the syscall will always remain visible, even if the transaction is aborted. This is an issue when transaction is used along with futex syscall, on pthread_cond_wait for instance, where the futex call might succeed but the transaction is rolled back leading the pthread_cond object in an inconsistent state. Glibc used to prevent it by always aborting a transaction before issuing a syscall. Linux 4.2 also decided to abort active transaction in syscalls which makes the glibc workaround superfluous. Worse, glibc transaction abortion leads to a performance issue on recent kernels where the HTM state is saved/restore lazily (v4.9). By aborting a transaction on every syscalls, regardless whether a transaction has being initiated before, GLIBS makes the kernel always save/restore HTM state (it can not even lazily disable it after a certain number of syscall iterations). Because of this shortcoming, Transactional Lock Elision is just enabled when it has been explicitly set (either by tunables of by a configure switch) and if kernel aborts HTM transactions on syscalls (PPC_FEATURE2_HTM_NOSC). It is reported that using simple benchmark [1], the context-switch is about 5% faster by not issuing a tabort in every syscall in newer kernels.

* Invert sense of list of i686-class processors in sysdeps/x86/cpu-features.h.Joseph Myers2018-09-201-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I noticed that sysdeps/x86/cpu-features.h had conditionals on whether to define HAS_CPUID, HAS_I586 and HAS_I686 with a long list of preprocessor macros for i686-and-later processors which however was out of date. This patch avoids the problem of the list getting out of date by instead having conditionals on all the (few, old) pre-i686 processors for which GCC has preprocessor macros, rather than the (many, expanding list) i686-and-later processors. It seems HAS_I586 and HAS_I686 are unused so the only effect of these macros being missing is that 32-bit glibc built for one of these processors would end up doing runtime detection of CPUID availability. i386 builds are prevented by a configure test so there is no need to allow for them here. __geode__ (no long nops?) and __k6__ (no CMOV, at least according to GCC) are conservatively handled as i586, not i686, here (as noted above, this is a theoretical distinction at present in that only HAS_CPUID appears to be used). Tested for x86. * sysdeps/x86/cpu-features.h [__geode__ || __k6__]: Handle like [__i586__ || __pentium__]. [__i486__]: Handle explicitly. (HAS_CPUID): Define to 1 if above macros are undefined. (HAS_I586): Likewise. (HAS_I686): Likewise.

* Fix tst-setcontext9 for optimized small stacks.Carlos O'Donell2018-09-191-0/+6
| | | | | | | | | | | | | | | | | | If the compiler reduces the stack usage in function f1 before calling into function f2, then when we swapcontext back to f1 and continue execution we may overwrite registers that were spilled to the stack while f2 was executing. Later when we return to f2 the corrupt registers will be reloaded from the stack and the test will crash. This was most commonly observed on i686 with __x86.get_pc_thunk.dx and needing to save and restore $edx. Overall i686 has few registers and the spilling to the stack is bound to happen, therefore the solution to making this test robust is to split function f1 into two parts f1a and f1b, and allocate f1b it's own stack such that subsequent execution does not overwrite the stack in use by function f2. Tested on i686 and x86_64. Signed-off-by: Carlos O'Donell <carlos@redhat.com>
* Fix mktime localtime offset confusionPaul Eggert2018-09-191-0/+10
| | | | | | | | | | | [BZ #23603] * include/time.h (__mktime_internal): The localtime offset is now of type long int instead of time_t. This is the longstanding type in glibc, and it is more than enough to represent difference between localtime and gmtime even if it is 32 bits and time_t is 64. Changing it now will let us avoid an unnecessary change when time_t is widened to 64 bits on 32-bit platforms. * time/mktime-internal.h (mktime_offset_t): Now long int.
* Merge mktime, timegm from upstream GnulibPaul Eggert2018-09-191-0/+70

Although it looks scary, it is almost all a byte-for-byte copy from Gnulib, and the Gnulib code has been tested reasonably well. * include/intprops.h: New file, copied from Gnulib. * include/verify.h, time/mktime-internal.h: New tiny files, simplified from Gnulib. * time/mktime.c: Copy from Gnulib. This has the following changes: Do not include config.h if DEBUG_MKTIME is nonzero. Include stdbool.h, intprops.h, verify.h. Include string.h only if needed. Include stdlib.h on MS-Windows. Include mktime-internal.h. (DEBUG_MKTIME): Default to 0, and simplify later uses. (NEED_MKTIME_INTERNAL, NEED_MKTIME_WINDOWS) (NEED_MKTIME_WORKING): Give default values to pacify -Wundef, which glibc uses. Default NEED_MKTIME_WORKING to DEBUG_MKTIME, to simplify later conditionals; default the others to zero. Use these conditionals to express only the code needed on the current platform. In uses of these conditionals, explicitly spell out how _LIBC affects things, so it’s easier to review from a glibc viewpoint. (WRAPV): Remove; no longer needed now that we have systematic overflow checking. (my_tzset, __tzset) [!_LIBC]: New function and macro, to better compartmentalize tzset issues. Move system-dependent tzsettish code here from mktime. (verify): Remove; now done by verify.h. All uses changed. (long_int): Use a more-conservative definition, to avoid integer overflow. (SHR): Remove, replacing with ... (shr): New function, which means we needn’t worry about side effects in args, and conversion analysis is simpler. (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT, TYPE_SIGNED, TYPE_MINIMUM) (TYPE_MAXIMUM, TIME_T_MIN, TIME_T_MAX, TIME_T_MIDPOINT) (time_t_avg, time_t_add_ok): Remove. (mktime_min, mktime_max): New constants. (leapyear, isdst_differ): Use bool for booleans. (ydhms_diff, guess_time_tm, ranged_convert, __mktime_internal): Use long_int, not time_t, for mktime differences. (long_int_avg): New function, replacing time_t_avg. INT_ADD_WRAPV replaces time_t_add_ok. (guess_time_tm): 6th arg is now long_int, not time_t const *. All uses changed. (convert_time): New function. (ranged_convert): Use it. (__mktime_internal): Last arg now points to mktime_offset_t, not time_t. All uses changed. This is a no-op on glibc, where mktime_offset_t is always time_t. Use int, not time_t, for UTC offset guess. Directly check for integer overflow instead of using a heuristic that works only 99.9...% of the time. Access *OFFSET only once, to avoid an unlikely race if the compiler delays a load and if this cascades into a signed integer overflow. (mktime): Move tzsettish code to my_tzset, and move localtime_offset to within mktime so that it doesn’t need a separate ifdef. (main) [DEBUG_MKTIME]: Speed up by using localtime_r instead of localtime. * time/timegm.c: Copy from Gnulib. This has the following changes: Include mktime-internal.h. [!_LIBC]: Include config.h and time.h. Do not include timegm.h or time_r.h. Make __mktime_internal a macro, and include mktime-internal.h to get its declaration. (timegm): Temporary is now mktime_offset_t, not time_t. This affects only Gnulib.
* Fix strstr bug with huge needles (bug 23637)Wilco Dijkstra2018-09-191-0/+8
| | | | | | | | | | | | | | | The generic strstr in GLIBC 2.28 fails to match huge needles. The optimized AVAILABLE macro reads ahead a large fixed amount to reduce the overhead of repeatedly checking for the end of the string. However if the needle length is larger than this, two_way_long_needle may confuse this as meaning the end of the string and return NULL. This is fixed by adding the needle length to the amount to read ahead. [BZ #23637] * string/test-strstr.c (pr23637): New function. (test_main): Add tests with longer needles. * string/strcasestr.c (AVAILABLE): Fix readahead distance. * string/strstr.c (AVAILABLE): Likewise.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The algorithm is exp(y * log(x)), where log(x) is computed with about 1.3*2^-68 relative error (1.5*2^-68 without fma), returning the result in two doubles, and the exp part uses the same algorithm (and lookup tables) as exp, but takes the input as two doubles and a sign (to handle negative bases with odd integer exponent). The __exp1 internal symbol is no longer necessary. There is separate code path when fma is not available but the worst case error is about 0.54 ULP in both cases. The lookup table and consts for log are 4168 bytes. The .rodata+.text is decreased by 37908 bytes on aarch64. The non-nearest rounding error is less than 1 ULP.

* Unify many bits/mman.h headers.Joseph Myers2018-09-181-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many bits/mman.h headers for Linux architectures have exactly the same contents, up to whitespace, comments and the number of leading 0s on constants. Specifically, this applies to architectures that, in the Linux kernel, either have no uapi/asm/mman.h, or have one that includes asm-generic/mman.h without any changes or additions relevant to glibc (this last case is the one that applies to Arm). It's not useful to have to duplicate the set of MAP_* constants in glibc for all such architectures and any new architectures with that property. Thus, this patch creates a generic sysdeps/unix/sysv/linux/bits/mman.h and removes all the architecture-specific versions that become unnecessary. Further unification remains possible after this patch. For example, the new bits/mman.h could become bits/mman-map-flags-generic.h so that it could also be used by architecture-specific bits/mman.h headers on architectures that use the generic flags but add architecture-specific ones to them. That would allow this common set of MAP_* definitions to be used on ia64 and x86 as well (architectures that include asm-generic/mman.h from their own uapi/asm/mman.h but define additional MAP_* values of their own).

| | | | | | | | | | | | | | | | | | | The ldbl-128ibm implementations of ceill and floorl call the corresponding double functions.

* Update siginfo constants from Linux kernel (bug 21286).Joseph Myers2018-09-171-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of Linux 4.17, siginfo headers in the Linux kernel have been largely unified across architectures (so various constants are defined with common values in include/uapi/asm-generic/siginfo.h even if not all architectures can generate those particular constants). This patch makes glibc reflect that unification and the current set of constants in that header as of Linux 4.18. Various constants are added to bits/siginfo-consts.h (under the same feature test macro conditions as the other constants with the same prefix), and removed from the ia64 bits/siginfo-consts-arch.h where they were previously there - this is not limited to constants added by the unification. Nothing is done about macros that are defined in include/uapi/asm-generic/siginfo.h with names with leading '__' (some of those are ia64-specific ones that remain in the ia64 bits/siginfo-consts-arch.h without the leading '__' there). A consequence of these changes is that TRAP_HWBKPT becomes available on AArch64 and all other architectures as requested in bug 21286. Tested for x86_64; tested with build-many-glibcs.py for ia64.

* Fix MIPS n32 pr_sigpend, pr_sighold, pr_flag type (bug 23656).Joseph Myers2018-09-141-0/+5
| | | | | | | | | | | | | | | | | | | As discussed at <https://sourceware.org/ml/libc-alpha/2018-09/msg00191.html> and followup discussions, the MIPS n32 definitions of pr_sigpend and pr_sighold in struct elf_prstatus, and pr_flag in struct elf_prpsinfo, are wrong to use unsigned long long int; actual n32 core dumps use a 32-bit type there, so userspace unsigned long int is correct for all MIPS ABIs. This patch removes the conditionals (also thereby aligning the structures with other architectures and so facilitating future unification of different versions of this header).
