Subject: [PATCH 4/5] copy_and_spawn_sgid: Avoid double calls to close()
Date: Tue, 27 Jul 2021 23:11:28 +0530 [thread overview]
Message-ID: <20210727174129.3612656-5-siddhesh@sourceware.org> (raw)
In-Reply-To: <20210727174129.3612656-1-siddhesh@sourceware.org>
If close() on infd and outfd succeeded, reset the fd numbers so that
we don't attempt to close them again.
