2018-03-23tipc: some cleanups in the file discover.cJon Maloy
To facilitate the coming changes in the neighbor discovery functionality we make some renaming and refactoring of that code. The functional changes in this commit are trivial, e.g., that we move the message sending call in tipc_disc_timeout() outside the spinlock protected region.

2016-04-07tipc: eliminate buffer leak in bearer layerJon Paul Maloy
When enabling a bearer we create a 'neigbor discoverer' instance by calling the function tipc_disc_create() before the bearer is actually registered in the list of enabled bearers. Because of this, the very first discovery broadcast message, created by the mentioned function, is lost, since it cannot find any valid bearer to use. Furthermore, the used send function, tipc_bearer_xmit_skb() does not free the given buffer when it cannot find a bearer, resulting in the leak of exactly one send buffer each time a bearer is enabled. This commit fixes this problem by introducing two changes: 1) Instead of attemting to send the discovery message directly, we let tipc_disc_create() return the discovery buffer to the calling function, tipc_enable_bearer(), so that the latter can send it when the enabling sequence is finished. 2) In tipc_bearer_xmit_skb(), as well as in the two other transmit functions at the bearer layer, we now free the indicated buffer or buffer chain when a valid bearer cannot be found.

2015-01-12tipc: involve namespace infrastructureYing Xue
Involve namespace infrastructure, make the "tipc_net_id" global variable aware of per namespace, and rename it to "net_id". In order that the conversion can be successfully done, an instance of networking namespace must be passed to relevant functions, allowing them to access the "net_id" variable of per namespace.
