Subject: [PATCH 05/17] netlink: Explicitly pass netlink sockets to operations
Date: Mon, 24 Jul 2023 16:09:24 +1000 [thread overview]
Message-ID: <20230724060936.952659-6-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20230724060936.952659-1-david@gibson.dropbear.id.au>
All the netlink operations currently implicitly use one of the two global
netlink sockets, sometimes depending on an 'ns' parameter. Change them
all to explicitly take the socket to use (or two sockets to use in the case
of the *_dup() functions). As well as making these functions strictly more
general, it makes the callers easier to follow because we're passing a
socket variable with a name rather than an unexplained '0' or '1' for the
ns parameter.
