From 54ff9ef36bdf84d469a098cbf8e2a103fbc77054 Mon Sep 17 00:00:00 2001 From: Marcelo Ricardo Leitner Date: Wed, 18 Mar 2015 14:50:43 -0300 Subject: ipv4, ipv6: kill ip_mc_{join, leave}_group and ipv6_sock_mc_{join, drop} in favor of their inner __ ones, which doesn't grab rtnl. As these functions need to operate on a locked socket, we can't be grabbing rtnl by then. It's too late and doing so causes reversed locking. So this patch: - move rtnl handling to callers instead while already fixing some reversed locking situations, like on vxlan and ipvs code. - renames __ ones to not have the __ mark: __ip_mc_{join,leave}_group -> ip_mc_{join,leave}_group __ipv6_sock_mc_{join,drop} -> ipv6_sock_mc_{join,drop} Signed-off-by: Marcelo Ricardo Leitner Acked-by: Hannes Frederic Sowa Signed-off-by: David S.
