Subject: login: Add nonstring attributes to struct utmp, struct utmpx [BZ #24899]
X-Git-Tag: upstream/2.34~2848
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2adefbafcdd2519ff43eca6891c77cd7b29ab62;p=platform%2Fupstream%2Fglibc.git

login: Add nonstring attributes to struct utmp, struct utmpx [BZ #24899]

Commit 7532837d7b03b3ca5b9a63d77a5bd81dd23f3d9c ("The
-Wstringop-truncation option new in GCC 8 detects common misuses")
added __attribute_nonstring__ to bits/utmp.h, but it did not update
the parallel bits/utmpx.h header.  In struct utmp, the nonstring
attribute for ut_id was missing.
