It is hard to understand why the refcnt is increased when it isn't done near the actual place the new reference is used. So using kref_get right before the place which requires the reference and in the same function helps to avoid accidental problems caused by incorrect reference counting. Signed-off-by:

This adds the commands BATADV_CMD_GET_TRANSTABLE_LOCAL and BATADV_CMD_GET_TRANSTABLE_GLOBAL, which correspond to the transtable_local and transtable_global debugfs files. The batadv_tt_client_flags enum is moved to the UAPI to expose it as part of the netlink API. Signed-off-by:

Debugfs is not netns aware. It thus has problems when the same interface name exists in multiple network name spaces. Work around this by not creating entries for interfaces in name spaces other than the default name space. This means meshes in network namespaces cannot be managed via debugfs, but there will soon be a netlink interface which is netns aware. Signed-off-by:

batman-adv tries to prevent the user from placing a batX soft interface into another batman mesh as a hard interface. It does this by walking up the devices list of parents and ensures they are all none batX interfaces. iflink can point to an interface in a different namespace, so also retrieve the parents name space when finding the parent and use it when doing the comparison.

The debug messages of _batadv_update_route were printed before the actual route change is done. At this point it is not really known which curr_router will be replaced. Thus the messages could print the wrong operation. Printing the debug messages after the operation was done avoids this problem. Signed-off-by:

The function batadv_send_skb_unicast is not acquiring a reference for an orig_node nor removing it from any datastructure. It still reduces the reference counter for an object which is still in the hands of the caller. This is confusing and can lead in the future to problems in the reference handling of the caller function. Signed-off-by:

The translation table (global, local) is usually the part of batman-adv which has the most dynamical allocated objects. Most of them (tt_local_entry, tt_global_entry, tt_orig_list_entry, tt_change_node, tt_req_node, tt_roam_node) are equally sized. So it makes sense to have them allocated from a kmem_cache for each type. This approach allowed a small wireless router (TP-Link TL-841NDv8; SLUB allocator) to store 34% more translation table entries compared to the current implementation.

This patch abstracts the forward packet creation into the new function batadv_forw_packet_alloc(). The queue counting and interface reference counters are now handled internally within batadv_forw_packet_alloc() and its batadv_forw_packet_free() counterpart. This should reduce the risk of having reference/queue counting bugs again and should increase code readibility. Signed-off-by:

The difference between tq1 and tq2 are calculated the same way in two separate functions. This patch moves the common code to a separate function 'batadv_iv_ogm_neigh_diff' which handles everything necessary. The other two functions can then handle errors and use the difference directly.

Now that the GW-mode code is algorithm specific, batman-adv expects the routing algorithm to implement some APIs to make it work. However, such APIs are not mandatory, therefore we might have algorithms not providing them. In this case all the sysfs knobs related to GW-mode should be deactivated to make sure that settings injected by the user for this feature are rejected. Signed-off-by:

Since the GW selection logic has been made routing protocol specific it is now possible for B.A.T.M.A.N V to have its own mechanism by providing the API implementation. Implement the GW specific API in the B.A.T.M.A.N. V protocol in order to provide a working GW selection mechanism. Signed-off-by:

Each routing protocol may have its own specific logic about gateway election which is potentially based on the metric being used. Create two GW specific API functions and move the current election logic in the B.A.T.M.A.N. IV specific code. Signed-off-by:
