Subject: [PATCH v3 02/11] icmp: Remove redundant initialisation of sendto() address
Date: Tue, 16 Jan 2024 16:16:09 +1100 [thread overview]
Message-ID: <20240116051618.2746103-3-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20240116051618.2746103-1-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().
