Subject: [PATCH 9/11] inet_diag: Introduce socket family checks
Date: Tue, 06 Dec 2011 21:59:15 +0400 [thread overview]
Message-ID: <4EDE57F3.1030505@parallels.com> (raw)
In-Reply-To: <4EDE573A.6040607@parallels.com>
The new API will specify family to work with. Teach the existing
socket walking code to bypass not interesting ones.
To preserve compatibility with existing behavior the _compat code
sets interesting family to AF_UNSPEC to dump them all.
