Commit a21a584d (tipc: fix neighbor detection problem after hw address change) introduces a race condition involving tipc_disc_delete() and tipc_disc_add/remove_dest that can cause TIPC to dereference the pointer to the bearer discovery request structure after it has been freed since a stray pointer is left in the bearer structure. In order to fix the issue, the process of resetting the discovery request handler is optimized: the discovery request handler and request buffer are just reset instead of being freed, allocated and initialized. As the request point is always valid and the request's lock is taken while the request handler is reset, the race doesn't happen any more.

The node map variable - 'nodes' in bearer structure is only used by bclink. When bclink accesses it, bc_lock is held. But when change it, for instance, in tipc_bearer_add_dest() or tipc_bearer_remove_dest() the bc_lock is not taken at all. To avoid any inconsistent data, we should always grab bc_lock while accessing node map variable.

As bearer pointer is known in tipc_l2_device_event(), it's unnecessary to search it again in tipc_disable_bearer(). If tipc_disable_bearer() is replaced with bearer_disable() in tipc_l2_device_event(), this will help us save a bit time when bearer is disabled.

The 'media_ptr' pointer in bearer structure which points to network device, is protected by RCU. So, before netdevice is released, synchronize_net() should be involved to prevent no any user of the netdevice on read side from accessing it after it is freed.

Now tipc routing hierarchy comprises the structures 'node', 'link'and 'bearer'. The whole hierarchy is protected by a big read/write lock, tipc_net_lock, to ensure that nothing is added or removed while code is accessing any of these structures. Obviously the locking policy makes node, link and bearer components closely bound together so that their relationship becomes unnecessarily complex. In the worst case, such locking policy not only has a negative influence on performance, but also it's prone to lead to deadlock occasionally. In order o decouple the complex relationship between bearer and node as well as link, the locking policy is adjusted as follows: - Bearer level RTNL lock is used on update side, and RCU is used on read side. Meanwhile, all bearer instances including broadcast bearer are saved into bearer_list array. - Node and link level All node instances are saved into two tipc_node_list and node_htable lists. The two lists are protected by node_list_lock on write side, and they are guarded with RCU lock on read side. All members in node structure including link instances are protected by node spin lock. - The relationship between bearer and node When link accesses bearer, it first needs to find the bearer with its bearer identity from the bearer_list array. When bearer accesses node, it can iterate the node_htable hash list with the node address to find the corresponding node. In the new locking policy, every component has its private locking solution and the relationship between bearer and node is very simple, that is, they can find each other with node address or bearer identity from node_htable hash list or bearer_list array. Until now above all changes have been done, so tipc_net_lock can be removed safely.

As the part of effort of eliminating tipc_net_lock, we decide to adjust the locking policy of media_ptr pointer protection: on write side, RTNL lock is use while on read side RCU read lock is applied.

Currently on both paths of message transmission and reception, the read lock of tipc_net_lock must be held before bearer is accessed, while the write lock of tipc_net_lock has to be taken before bearer is configured. Although it can ensure that bearer is always valid on the two data paths, link and bearer is closely bound together. So as the part of effort of removing tipc_net_lock, the locking policy of bearer protection will be adjusted as below: on the two data paths, RCU is used, and on the configuration path of bearer, RTNL lock is applied. Now RCU just covers the path of message reception. To make it possible to protect the path of message transmission with RCU, link should not use its stored bearer pointer to access bearer, but it should use the bearer identity of its attached bearer as index to get bearer instance from bearer_list array, which can help us decouple the relationship between bearer and link. As a result, bearer on the path of message transmission can be safely protected by RCU when we access bearer_list array within RCU lock protection.

Currently the 'tipc_ptr' pointer is protected by tipc_net_lock write lock on write side, and RCU read lock is applied to read side. In addition, there have two paths on write side where we may change variables pointed by the 'tipc_ptr' pointer: one is to configure bearer by tipc-config tool and another one is that bearer status is changed by notification events of its attached interface. But on the latter path, we improperly deem that accessing 'tipc_ptr' pointer happens on read side with rcu_read_lock() although some variables pointed by the 'tipc_ptr' pointer are changed possibly. Moreover, as now the both paths are guarded by RTNL lock, it's better to adjust the locking policy of 'tipc_ptr' pointer protection, allowing RTNL instead of tipc_net_lock write lock to protect it on write side, which will help us purge tipc_net_lock in the future.

There have two paths where we can configure or change bearer status: one is that bearer is configured from user space with tipc-config tool; another one is that bearer is changed by notification events from its attached interface. On the first path, one dedicated config_mutex lock is guarded; on the latter path, RTNL lock has been placed to serialize the process of dealing with interface events. So, if RTNL lock is also used to protect the first path, this will not only extremely help us simplify current locking policy, but also config_mutex lock can be deleted as well.

Currently broadcasts are handled in network RX context, where the packets are sent through netif_rx. This means that the number of macvlans will be constrained by the capacity of netif_rx. For example, setting up 4096 macvlans practically causes all broadcast packets to be dropped as the default netif_rx queue size simply can't handle 4096 skbs being stuffed into it all at once. Fundamentally, we need to ensure that the amount of work handled in each netif_rx backlog run is constrained. As broadcasts are anything but constrained, it either needs to be limited per run or moved to process context. This patch picks the second option and moves all broadcast handling bar the trivial case of packets going to a single interface into a work queue. Obviously there also needs to be a limit on how many broadcast packets we postpone in this way. I've arbitrarily chosen tx_queue_len of the master device as the limit (act_mirred also happens to use this parameter in a similar way). In order to ensure we don't exceed the backlog queue we will use netif_rx_ni instead of netif_rx for broadcast packets.

This patch adds the helper __dev_forward_skb which is identical to dev_forward_skb except that it doesn't actually inject the skb into the stack. This is useful where we wish to have finer control over how the packet is injected, e.g., via netif_rx_ni or netif_receive_skb.
