* y2038: Add __USE_TIME_BITS64 support for struct utimbufAdhemerval Zanella2021-06-151-0/+5
| | | | | | | | The __USE_TIME_BITS64 is not defined internally yet. Reviewed-by: Lukasz Majewski <lukma@denx.de> Reviewed-by: Carlos O'Donell <carlos@redhat.com> Tested-by: Carlos O'Donell <carlos@redhat.com>
* io: Fix sporadic test failures in io/tst-statFlorian Weimer2021-06-101-4/+4
| | | | | | | | support_stat_nanoseconds cannot restore the ctime time, and this may lead to sporadic test failures. Therefore, probe for nanoseconds support before the initial statx call. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Add missing symbols to Version filesFlorian Weimer2021-06-021-0/+1
| | | | | | | | | Some symbols have explicit versioned_symbol or compat_symbol markers in the sources, but no corresponding entry in the Versions files. This presently works because the local: * directive is only applied to the base version. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
* Annotate additional APIs with GCC attribute access.Martin Sebor2021-05-062-6/+11
| | | | | | | | | | | | | | | | This change continues the improvements to compile-time out of bounds checking by decorating more APIs with either attribute access, or by explicitly providing the array bound in APIs such as tmpnam() that expect arrays of some minimum size as arguments. (The latter feature is new in GCC 11.) The only effects of the attribute and/or the array bound is to check and diagnose calls to the functions that fail to provide a sufficient number of elements, and the definitions of the functions that access elements outside the specified bounds. (There is no interplay with _FORTIFY_SOURCE here yet.) Tested with GCC 7 through 11 on x86_64-linux.

* S390: Don't test nanoseconds in io/tst-stat.cStefan Liebler2021-03-261-2/+5
| | | | | | | | | | | Both new tests io/tst-stat and io/tst-stat-lfs (_FILE_OFFSET_BITS=64) are comparing the nanosecond fields with the statx result. Unfortunately on s390(31bit) those fields are always zero if old KABI with non-LFS support is used. With _FILE_OFFSET_BITS=64 stat is using statx internally. As suggested by Adhemerval this patch disables the nanosecond check for s390(31bit). Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
