The 'tipc_node_list' is guarded by tipc_net_lock and 'links' array defined in 'tipc_node' structure is protected by node lock as well. Without acquiring the two locks in named_cluster_distribute() a fatal oops may happen in case that a destroyed link might be got and then accessed. Therefore, above mentioned two locks must be held in named_cluster_distribute() to prevent the issue from happening accidentally. As 'links' array in node struct must be protected by node lock, we have to move the code of selecting an active link from tipc_link_xmit() to named_cluster_distribute() and then call __tipc_link_xmit() with the selected link to deliver name messages.

Due to the lacking of any credential, it's allowed to accept commands requested from remote nodes to query the local node status, which is prone to involve potential security risks. Instead, if we login to a remote node with ssh command, this approach is not only more safe than the remote management feature, but also it can give us more permissions like changing the remote node configuration. So it's reasonable for us to obsolete the remote management feature now. Signed-off-by:

tipc_node_create routine doesn't need to check whether a node object specified with a node address exists or not because its caller(ie, tipc_disc_recv_msg routine) has checked this before calling it. Signed-off-by:

This patch replaces rcu_assign_pointer(x, NULL) with RCU_INIT_POINTER(x, NULL) The rcu_assign_pointer() ensures that the initialization of a structure is carried out before storing a pointer to that structure. And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by:

The bond send arp request to indicate that the slave is active, and if the bond dev is a vlan dev, it will set the vlan tag in skb to notice the vlan group, but the bond could only send a skb with 802.1q proto, not support for QinQ. So add outer tag for lower vlan tag and inner tag for upper vlan tag to support QinQ, The new skb will be consist of two vlan tag just like this: dst mac | src mac | outer vlan tag | inner vlan tag | data | ..... If We don't need QinQ, the inner vlan tag could be set to 0 and use outer vlan tag as a normal vlan group. Using "ip link" to configure the bond for QinQ and add test log: ip link add link bond0 bond0.20 type vlan proto 802.1ad id 20 ip link add link bond0.20 bond0.20.200 type vlan proto 802.1q id 200 ifconfig bond0.20 11.11.20.36/24 ifconfig bond0.20.200 11.11.200.36/24 echo +11.11.200.37 > /sys/class/net/bond0/bonding/arp_ip_target 90:e2:ba:07:4a:5c (oui Unknown) > Broadcast, ethertype 802.1Q-QinQ (0x88a8),length 50: vlan 20, p 0,ethertype 802.1Q, vlan 200, p 0, ethertype ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 11.11.200.37 tell 11.11.200.36, length 28 90:e2:ba:06:f9:86 (oui Unknown) > 90:e2:ba:07:4a:5c (oui Unknown), ethertype 802.1Q-QinQ (0x88a8), length 50: vlan 20, p 0, ethertype 802.1Q, vlan 200, p 0, ethertype ARP, Ethernet (len 6), IPv4 (len 4), Reply 11.11.200.37 is-at 90:e2:ba:06:f9:86 (oui Unknown), length 28 v1->v2: remove the comment "TODO: QinQ?".

Since the early days TX stops if there isn't enough free pending slots to consume a maximum sized (slot-wise) packet. Probably the reason for that is to avoid the case when we don't have enough free pending slot in the ring to finish the packet. But if we make sure that the pending ring has the same size as the shared ring, that shouldn't really happen. The frontend can only post packets which fit the to the free space of the shared ring. If it doesn't, the frontend has to stop, as it can only increase the req_prod when the whole packet fits onto the ring. This patch avoid using this checking, makes sure the 2 ring has the same size, and remove a checking from the callback. As now we don't stop the NAPI instance on this condition, we don't have to wake it up if we free pending slots up. Signed-off-by:

Writing first to the AFE registers, and then the VCO, RCAL, RC_CAL registers turned out to unveil some spurious MDIO read/write failures which would make the workaround partially applied. The fix is to write first to the VCO, RCAL, RC_CAL registers, and then write to the AFE registers. Signed-off-by:
