2017-09-28batman-adv: Remove unnecessary parenthesesSven Eckelmann
checkpatch introduced with commit 63b7c73ec86b ("checkpatch: add --strict check for ifs with unnecessary parentheses") an additional test which identifies some unnecessary parentheses. Remove these unnecessary parentheses to avoid the warnings and to unify the coding style slightly more.

2016-10-30batman-adv: Simple (re)broadcast avoidanceLinus Lüssing
With this patch, (re)broadcasting on a specific interfaces is avoided: * No neighbor: There is no need to broadcast on an interface if there is no node behind it. * Single neighbor is source: If there is just one neighbor on an interface and if this neighbor is the one we actually got this broadcast packet from, then we do not need to echo it back. * Single neighbor is originator: If there is just one neighbor on an interface and if this neighbor is the originator of this broadcast packet, then we do not need to echo it back. Goodies for BATMAN V: ("Upgrade your BATMAN IV network to V now to get these for free!") Thanks to the split of OGMv1 into two packet types, OGMv2 and ELP that is, we can now apply the same optimizations stated above to OGMv2 packets, too. Furthermore, with BATMAN V, rebroadcasts can be reduced in certain multi interface cases, too, where BATMAN IV cannot. This is thanks to the removal of the "secondary interface originator" concept in BATMAN V.

2016-10-19batman-adv: Use proper name for fragments list headSven Eckelmann
The batman-adv codebase is using "list" for the list node (prev/next) and <list content descriptor>+"_list" for the head of a list. Not using this naming scheme can up in confusions because list_head is used for both the head of the list and the list node (prev/next) in each item of the list.

2016-10-17batman-adv: Modify neigh_list only with rcu-list functionsSven Eckelmann
The batadv_hard_iface::neigh_list is accessed via rcu based primitives. Thus all operations done on it have to fulfill the requirements by RCU. So using non-RCU mechanisms like hlist_add_head is not allowed because it misses the barriers required to protect concurrent readers when accessing the data behind the pointer.

2016-08-09batman-adv: Allow to disable debugfs supportSven Eckelmann
The files provided by batman-adv via debugfs are currently converted to netlink. Tools which are not yet converted to use the netlink interface may still rely on the old debugfs files. But systems which already upgraded their tools can save some space by disabling this feature. The default configuration of batman-adv on amd64 can reduce the size of the module by around 11% when this feature is disabled. $ size net/batman-adv/batman-adv.ko* text data bss dec hex filename 150507 10395 4160 165062 284c6 net/batman-adv/batman-adv.ko.y 137106 7099 2112 146317 23b8d net/batman-adv/batman-adv.ko.n Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>

Split the API in subobjects in order to improve definition readability. At the same time, remove the "bat_" prefix from the API object and its fields names.

The callers of the functions using batadv_hard_iface objects already make sure that they hold a valid reference. The subfunctions don't have to check whether the reference counter is > 0 because this was checked by the callers.

2016-05-10batman-adv: Check hard_iface refcnt before calling functionSven Eckelmann
The batadv_hardif_list list is checked in many situations and the items in this list are given to specialized functions to modify the routing behavior. At the moment each of these called functions has to check itself whether the received batadv_hard_iface has a refcount > 0 before it can increase the reference counter and use it in other objects. This can easily lead to problems because it is not easily visible where all callers of a function got the batadv_hard_iface object from and whether they already hold a valid reference. Checking the reference counter directly before calling a subfunction with a pointer from the batadv_hardif_list avoids this problem.

2016-04-29batman-adv: Fix reference counting of hardif_neigh_node object for neigh_nodeSven Eckelmann
The batadv_neigh_node was specific to a batadv_hardif_neigh_node and held an implicit reference to it. But this reference was never stored in form of a pointer in the batadv_neigh_node itself. Instead batadv_neigh_node_release depends on a consistent state of hard_iface->neigh_list and that batadv_hardif_neigh_get always returns the batadv_hardif_neigh_node object which it has a reference for. But batadv_hardif_neigh_get cannot guarantee that because it is working only with rcu_read_lock on this list. It can therefore happen that a neigh_addr is in this list twice or that batadv_hardif_neigh_get cannot find the batadv_hardif_neigh_node for an neigh_addr due to some other list operations taking place at the same time. Instead add a batadv_hardif_neigh_node pointer directly in batadv_neigh_node which will be used for the reference counter decremented on release of batadv_neigh_node.

batman-adv uses a self-written reference implementation which is just based on atomic_t. This is less obvious when reading the code than kref and therefore increases the change that the reference counting will be missed.
