Subject: [PATCH v5 13/15] util: Rename sock_l4_dualstack() to sock_l4_dualstack_any()
Date: Tue, 2 Dec 2025 15:02:13 +1100 [thread overview]
Message-ID: <20251202040215.2351792-14-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20251202040215.2351792-1-david@gibson.dropbear.id.au>
Stefano correctly noted that the fact a socket is dual-stack doesn't
necessarily imply that it is bound to a wildcard address. While that's the
only case we use for dual-stack sockets, there may be others. Therefore
rename this function to make it clearer that it always uses a wildcard
bind.
