Subject: [PATCH 3/5] util: Add missing O_CLOEXEC for !HAS_GETRANDOM path
Date: Fri, 21 Aug 2026 15:04:01 +1000 [thread overview]
Message-ID: <20260821050403.170891-4-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20260821050403.170891-1-david@gibson.dropbear.id.au>
It rarely matters, since we usually have getrandom(), but in case we don't
our open() of /dev/random was missing O_CLOEXEC, which can cause clang
warnings.
