+Subject: [PATCH 01/17] batman-adv: Avoid u32 overflow during gateway select
+
+The gateway selection based on fast connections is using a single value
+calculated from the average tq (0-255) and the download bandwidth (in
+100Kibit). The formula for the first step (tq ** 2 * 10000 * bandwidth)
+tends to overflow a u32 with low bandwidth settings like 50 [100KiBit]
+and a tq value of over 92.
+
+Changing this to a 64 bit unsigned integer allows to support a
+bandwidth_down with up to ~2.8e10 [100KiBit] and a perfect tq of 255. This
+is ~6.6 times higher than the maximum possible value of the gateway
+announcement TVLV.
+
+This problem only affects the non-default gw_sel_class 1.

+Subject: [PATCH 02/17] batman-adv: avoid DAT to mess up LAN state
+
+When a node running DAT receives an ARP request from the LAN for the
+first time, it is likely that this node will request the ARP entry
+through the distributed ARP table (DAT) in the mesh.
+
+Once a DAT reply is received the asking node must check if the MAC
+address for which the IP address has been asked is local. If it is, the
+node must drop the ARP reply bceause the client should have replied on
+its own locally.
+
+Forwarding this reply means fooling any L2 bridge (e.g. Ethernet
+switches) lying between the batman-adv node and the LAN. This happens
+because the L2 bridge will think that the client sending the ARP reply
+lies somewhere in the mesh, while this node is sitting in the same LAN.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Bitwise OR/AND assignments in C aren't guaranteed to be atomic. One
+OGM handler might undo the set/clear of a specific bit from another
+handler run in between.
+
+Fix this by using the atomic set_bit()/clear_bit() functions.

+Subject: [PATCH 07/17] batman-adv: Fix potential synchronization issues in
+ mcast tvlv handler
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+So far the mcast tvlv handler did not anticipate the processing of
+multiple incoming OGMs from the same originator at the same time. This
+can lead to various issues:
+
+* Broken refcounting: For instance two mcast handlers might both assume
+ that an originator just got multicast capabilities and will together
+ wrongly decrease mcast.num_disabled by two, potentially leading to
+ an integer underflow.
+
+* Potential kernel panic on hlist_del_rcu(): Two mcast handlers might
+ one after another try to do an
+ hlist_del_rcu(&orig->mcast_want_all_*_node). The second one will
+ cause memory corruption / crashes.
+ (Reported by: Sven Eckelmann <sven@narfation.org>)
+
+Right in the beginning the code path makes assumptions about the current
+multicast related state of an originator and bases all updates on that. The
+easiest and least error prune way to fix the issues in this case is to
+serialize multiple mcast handler invocations with a spinlock.

+Subject: [PATCH 10/17] batman-adv: protect tt_local_entry from concurrent
+ delete events
+
+The tt_local_entry deletion performed in batadv_tt_local_remove() was neither
+protecting against simultaneous deletes nor checking whether the element was
+still part of the list before calling hlist_del_rcu().
+
+Replacing the hlist_del_rcu() call with batadv_hash_remove() provides adequate
+protection via hash spinlocks as well as an is-element-still-in-hash check to
+avoid 'blind' hash removal.
+
+Fixes: 2443ba3 ("batman-adv: roaming handling mechanism redesign")

+Subject: [PATCH 12/17] batman-adv: initialize up/down values when adding a
+ gateway
+
+Without this initialization, gateways which actually announce up/down
+bandwidth of 0/0 could be added. If these nodes get purged via
+_batadv_purge_orig() later, the gw_node structure does not get removed
+since batadv_gw_node_delete() updates the gw_node with up/down
+bandwidth of 0/0, and the updating function then discards the change
+and does not free gw_node.
+
+This results in leaking the gw_node structures, which references other
+structures: gw_node -> orig_node -> orig_node_ifinfo -> hardif. When
+removing the interface later, the open reference on the hardif may cause
+hangs with the infamous "unregister_netdevice: waiting for mesh1 to
+become free. Usage count = 1" message.

+Subject: [PATCH] batman-adv: introduce 'no_rebroadcast' option
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This patch introduces a new sysfs option named "no_rebroadcast" on
+a per hard interface basis. It allows manually enabling a split-horizon
+like behaviour for the layer 2 multicast payload frames, in that
+incoming multicast payload frames on such a hard interface are only
+being rebroadcasted on all interfaces except the incoming one instead
+of being rebroadcasted on all interfaces.
+
+Such an option should only be enabled if you are certain that these
+rebroadcasts are unnecessary. This is usually the case for instance
+for point-to-point wifi longshots or wired links.
+
+This option can especially safe a significant amount of upload overhead
+if the neighbourhood on a link is rather large, for instance in some
+transitive, symmetric VPN configurations.
+
+Using this option wrongly will break your mesh network, use this option
+wisely and at your own risk!
