Subject: pthread: Use 64 bit time_t stat internally for sem_open (BZ #28880)
X-Git-Tag: glibc-2.36~678
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=894755e16e10725c94bec3f910d35730614a7d00;p=thirdparty%2Fglibc.git

pthread: Use 64 bit time_t stat internally for sem_open (BZ #28880)

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.
