| | | | | | | | | | | | | | | | | | | | | | | | | | On success, the function netdev_alloc_skb initializes the dev field of its result to its first argument, so this doesn't have to be done in the calling context. The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression skb,privn,e; @@ skb = netdev_alloc_skb(privn,...); ... when strict ( -skb->dev = privn; | ?skb = e ) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S.

* tipc: correct usage of spin_lock() vs spin_lock_bh()Jon Paul Maloy2014-02-171-3/+3
| | | | | | | | | | | | | | | I commit e099e86c9e24fe9aff36773600543eb31d8954d ("tipc: add node_lock protection to link lookup function") we are calling spin_lock(&node->lock) directly instead of indirectly via the tipc_node_lock(node) function. However, tipc_node_lock() is using spin_lock_bh(), not spin_lock(), something leading to unbalanced usage in one place, and a smatch warning. We fix this by consistently using tipc_node_lock()/unlock() in in the places touched by the mentioned commit. Signed-off-by: Jon Maloy <jon.maloy@ericsson.com> Signed-off-by: David S.

* tipc: fix a loop style problemJon Paul Maloy2014-02-171-5/+5
| | | | | | | | | | | | | | | | | | In commit 7d33939f475d403e79124e3143d7951dcfe8629f ("tipc: delay delete of link when failover is needed") we introduced a loop for finding and removing a link pointer in an array. The removal is done after we have left the loop, giving the impression that one may remove the wrong pointer if no matching element is found. This is not really a bug, since we know that there will always be a matching element, but it looks wrong, and causes a smatch warning. We fix this loop with this commit.

* ip_tunnel: return more precise errno value when adding tunnel failsFlorian Westphal2014-02-171-5/+10
| | | | | | | | | | | Currently this always returns ENOBUFS, because the return value of __ip_tunnel_create is discarded. A more common failure is a duplicate name (EEXIST).
