Subject: [PATCH v2 03/12] icmp: Remove redundant initialisation of sendto() address
Date: Thu, 21 Dec 2023 17:53:18 +1100 [thread overview]
Message-ID: <20231221065327.1307827-4-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20231221065327.1307827-1-david@gibson.dropbear.id.au>
We initialise the address portion of the sockaddr for sendto() to the
unspecified address, but then always overwrite it with the actual
destination address before we call the sendto().
