Subject: [PATCH] inptl: Use 64 bit time_t stat internally for sem_open (BZ #28880)
Date: Fri, 11 Feb 2022 09:50:18 -0300 [thread overview]
Message-ID: <20220211125018.4168997-1-adhemerval.zanella@linaro.org> (raw)
The __sem_check_add_mapping internal stat calls fails with
EOVERFLOW if system time is larger than 32 bit.
It is a missing spot from 52a5fe70a2c fix to use 64 bit stat
internally.
Checked on x86_64-linux-gnu and i686-linux-gnu.
