From fa7f86f1bb5d8f08d10442a546252d2670b26f41 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Thu, 16 Aug 2012 12:09:06 +0000 Subject: tipc: optimize the initialization of network device notifier Ethernet media initialization is only done when TIPC is started or switched to network mode. So the initialization of the network device notifier structure can be moved out of this function and done statically instead.

But the ptype_lock has been taken by dev_add_pack() on CPU0, so at this time the dev_add_pack() running on CPU1 has to be busy looping. Time 2 on CPU0: netif_receive_skb()->recv_msg()->tipc_recv_msg() At time 2, an incoming TIPC packet arrives at CPU0, hence tipc_recv_msg() will be invoked. In tipc_recv_msg(), it first wants to hold tipc_net_lock. At the moment, below scenario happens: On CPU0, below is our sequence of taking locks: lock(ptype_lock)->lock(tipc_net_lock) On CPU1, our sequence of taking locks looks like: lock(tipc_net_lock)->lock(ptype_lock) Obviously deadlock may happen in this case. But please note the deadlock possibly doesn't occur at all when the first TIPC bearer is enabled. Before enable_bearer() -- running on CPU1 does not hold ptype_lock, so the TIPC receive handler (i.e. recv_msg()) is not registered successfully via dev_add_pack(), so the tipc_recv_msg() cannot be called by recv_msg() even if a TIPC message comes to CPU0. But when the second TIPC bearer is registered, the deadlock can perhaps really happen. To fix it, we will push the work of registering TIPC protocol handler into workqueue context. After the change, both paths taking ptype_lock are always in process contexts, thus, the deadlock should never occur.

Biederman" Date: Fri, 7 Sep 2012 20:12:54 +0000 Subject: netlink: Rename pid to portid to avoid confusion It is a frequent mistake to confuse the netlink port identifier with a process identifier. Try to reduce this confusion by renaming fields that hold port identifiers portid instead of pid. I have carefully avoided changing the structures exported to userspace to avoid changing the userspace API. I have successfully built an allyesconfig kernel with this change. Signed-off-by: "Eric W.
