Subject: [PATCH 3/3] dhcp-transport: Initialize the udp_fd field
Date: Sun, 8 May 2022 01:54:34 +0200 [thread overview]
Message-ID: <20220507235434.11693-4-greg@gregdf.com> (raw)
In-Reply-To: <20220507235434.11693-1-greg@gregdf.com>
Initialize the udp_fd field to -1 in _dhcp_default_transport_new to
prevent future mistakes where a random FD is closed when the transport
is closed before the field is initialized.
