* Improve test coverage of strlen functionSunil K Pandey2021-06-021-1/+14
| | | | | | | | | | | This patch covers the following conditions: - Strings start with different alignments and end at the page boundary with less than 64 byte length. - Strings starts with different alignments and cross page boundary with fixed length. Reviewed-by: H.J. Lu <hjl.tools@gmail.com>
* x86: Expand bench-memcmp.c and test-memcmp.cNoah Goldstein2021-05-181-6/+34
| | | | | | | | | | | No bug. This commit adds some additional performance test cases to bench-memcmp.c and test-memcmp.c. The new benchtests include some medium range sizes, as well as small sizes near page cross. The new correctness tests correspond with the new benchtests though add some additional cases for checking the page cross logic.

* x86: Expanding test-memmove.c, test-memcpy.c, bench-memcpy-large.cnoah2021-04-162-53/+76
| | | | | | | | | | | | No Bug. This commit expanding the range of tests / benchmarks for memmove and memcpy. The test expansion is mostly in the vein of increasing the maximum size, increasing the number of unique alignments tested, and testing both source < destination and vice versa. The benchmark expansaion is just to increase the number of unique alignments. test-memcpy, test-memccpy, test-mempcpy, test-memmove, and tst-memmove-overflow all pass.

* string: Enable __FORTIFY_LEVEL=3Siddhesh Poyarekar2020-12-312-13/+22
| | | | | | This change enhances fortified string functions to use __builtin_dynamic_object_size under _FORTIFY_SOURCE=3 whenever the compiler supports it.

* Don't use nested function in test-ffsSiddhesh Poyarekar2020-11-121-22/+14
| | | | | There is no real need to use a nested function in that test, so break it out so that it can build with clang too.
* Use __builtin___stpncpy_chk when availableSiddhesh Poyarekar2020-11-121-1/+8
| | | | | | | | | | | | The builtin has been available in gcc since 4.7.0 and in clang since 2.6. This fixes stpncpy fortification with clang since it does a better job of plugging in __stpncpy_chk in the right place than the header hackery. This has been tested by building and running all tests with gcc 10.2.1 and also with clang tip as of a few days ago (just the tests in debug/ since running all tests don't work with clang at the moment) to make sure that both compilers pass the stpncpy tests.
* Remove __warn_memset_zero_len [BZ #25399]Siddhesh Poyarekar2020-11-051-15/+0
| | | | | | | | | | | | | | Non-gcc compilers (clang and possibly other compilers that do not masquerade as gcc 5.0 or later) are unable to use __warn_memset_zero_len since the symbol is no longer available on glibc built with gcc 5.0 or later. While it was likely an oversight that caused this omission, the fact that it wasn't noticed until recently (when clang closed the gap on _FORTIFY_SUPPORT) that the symbol was missing. Given that both gcc and clang are capable of doing this check in the compiler, drop all remaining signs of __warn_memset_zero_len from glibc so that no more objects are built with this symbol in future.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The per-thread state is refactored two use two strategies: 1. The default one uses a TLS structure, which will be placed in the static TLS space (using __thread keyword). 2. Linux allocates via struct pthread and access it through THREAD_* macros. The default strategy has the disadvantage of increasing libc.so static TLS consumption and thus decreasing the possible surplus used in some scenarios (which might be mitigated by BZ#25051 fix). It is used only on Hurd, where accessing the thread storage in the in single thread case is not straightforward (afaiu, Hurd developers could correct me here). The fallback static allocation used for allocation failure is also removed: defining its size is problematic without synchronizing with translated messages (to avoid partial translation) and the resulting usage is not thread-safe.

* S390: Fix handling of needles crossing a page in strstr z15 ifunc-variant. ↵Stefan Liebler2019-11-271-6/+35
| | | | | | | | | | | | | | | | | [BZ #25226] If the specified needle crosses a page-boundary, the s390-z15 ifunc variant of strstr truncates the needle which results in invalid results. This is fixed by loading the needle beyond the page boundary to v18 instead of v16. The bug is sometimes observable in test-strstr.c in check1 and check2 as the haystack and needle is stored on stack. Thus the needle can be on a page boundary. check2 is now extended to test haystack / needles located on stack, at end of page and on two pages. This bug was introduced with commit 6f47401bd5fc71209219779a0426170a9a7395b0 ("S390: Add arch13 strstr ifunc variant.") and is already released in glibc 2.30.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | string/tester.c contains code that correctly triggers various GCC warnings about dubious uses of string functions (uses that are being deliberately tested there), and duly disables those warnings around the relevant code. A change in GCC mainline resulted in this code failing to compile with a -Warray-bounds error, despite the location with the error having -Warray-bounds already disabled. This has been reported as <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91890>. This patch avoids that problem and possible future issues with these diagnostics by moving all the warning disabling in this file to top level, as suggested by Florian in <https://sourceware.org/ml/libc-alpha/2019-10/msg00033.html>, rather than only doing it locally around specific function calls. Tested with build-many-glibcs.py for aarch64-linux-gnu with GCC mainline (with only the conform/ failures noted in <https://sourceware.org/ml/libc-alpha/2019-10/msg00043.html>). * string/tester.c: Ignore -Warray-bounds and -Wmemset-transposed-args at top level.

* Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis2019-10-013-34/+57

This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I *removed* copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER.

Rewrite the comment explaining what the machine-specific variants of this file should do. * sysdeps/unix/sysv/linux/ia64/bits/endian.h: Move to sysdeps/ia64. * sysdeps/aarch64/bits/endian.h * sysdeps/alpha/bits/endian.h * sysdeps/arm/bits/endian.h * sysdeps/csky/bits/endian.h * sysdeps/hppa/bits/endian.h * sysdeps/ia64/bits/endian.h * sysdeps/m68k/bits/endian.h * sysdeps/microblaze/bits/endian.h * sysdeps/mips/bits/endian.h * sysdeps/nios2/bits/endian.h * sysdeps/powerpc/bits/endian.h * sysdeps/riscv/bits/endian.h * sysdeps/s390/bits/endian.h * sysdeps/sh/bits/endian.h * sysdeps/sparc/bits/endian.h * sysdeps/x86/bits/endian.h: Rename to endianness.h; canonicalize form of file; remove redundant definitions of __FLOAT_WORD_ORDER. * sysdeps/powerpc/bits/endianness.h: Remove logic to check for broken compilers. * ctype/ctype.h * sysdeps/aarch64/nptl/bits/pthreadtypes-arch.h * sysdeps/arm/nptl/bits/pthreadtypes-arch.h * sysdeps/csky/nptl/bits/pthreadtypes-arch.h * sysdeps/ia64/ieee754.h * sysdeps/ieee754/ieee754.h * sysdeps/ieee754/ldbl-128/ieee754.h * sysdeps/ieee754/ldbl-128ibm/ieee754.h * sysdeps/m68k/nptl/bits/pthreadtypes-arch.h * sysdeps/microblaze/nptl/bits/pthreadtypes-arch.h * sysdeps/mips/ieee754/ieee754.h * sysdeps/mips/nptl/bits/pthreadtypes-arch.h * sysdeps/nios2/nptl/bits/pthreadtypes-arch.h * sysdeps/nptl/pthread.h * sysdeps/riscv/nptl/bits/pthreadtypes-arch.h * sysdeps/sh/nptl/bits/pthreadtypes-arch.h * sysdeps/sparc/sparc32/ieee754.h * sysdeps/unix/sysv/linux/generic/bits/stat.h * sysdeps/unix/sysv/linux/generic/bits/statfs.h * sysdeps/unix/sysv/linux/sys/acct.h * wctype/bits/wctype-wchar.h: Include bits/endian.h, not endian.h. * sysdeps/unix/sysv/linux/hppa/pthread.h: Don’t include endian.h. * sysdeps/mips/ieee754/ieee754.h: Use __LDBL_MANT_DIG__ in ifdefs, instead of LDBL_MANT_DIG. Only include float.h when __LDBL_MANT_DIG__ is not predefined, in which case define __LDBL_MANT_DIG__ to equal LDBL_MANT_DIG.
