fib_semantic_match() requires that if the type doesn't signal an automatic error, it must be of type RTN_UNICAST, RTN_LOCAL, RTN_BROADCAST, RTN_ANYCAST, or RTN_MULTICAST. Checking this every route lookup is pointless work. Instead validate it during route insertion, via fib_create_info(). Also, there was nothing making sure the type value was less than RTN_MAX, so add that missing check while we're here. Signed-off-by: -

This allows any caller to be prefaced by any specific pr_fmt to better identify which device driver is using this function inappropriately. Add terminating newline. Signed-off-by:

When trying to associate a net_device with another net_device which already exists, batman-adv assumes that this interface is a fully initialized batman mesh interface without checking it. The behaviour when accessing data behind netdev_priv of a random net_device is undefined and potentially dangerous. Reported-by:

Batman-adv works with "hard interfaces" as well as "soft interfaces". The new name should better make clear which kind of interfaces this list stores. Signed-off-by: -

It might be possible that 2 threads access the same data in the same rcu grace period. The first thread calls call_rcu() to decrement the refcount and free the data while the second thread increases the refcount to use the data. To avoid this race condition all refcount operations have to be atomic. Reported-by:

When printing the soft interface table the number of entries in the softif neigh list are first being counted and a fitting buffer allocated. After that the softif neigh list gets locked again and the buffer printed - which has the following two issues: For one thing, the softif neigh list might have grown when reacquiring the rcu lock, which results in writing outside of the allocated buffer. Furthermore 31 Bytes are not enough for printing an entry with a vid of more than 2 digits. The manual buffering is unnecessary, we can safely print to the seq directly during the rcu_read_lock().

When unicast_send_skb() is increasing the orig_node's refcount another thread might have been freeing this orig_node already. We need to increase the refcount in the rcu read lock protected area to avoid that. Signed-off-by:

The rcu protected macros rcu_dereference() and rcu_assign_pointer() for the bat_priv->curr_gw need to be used, as well as spin/rcu locking. Otherwise we might end up using a curr_gw pointer pointing to already freed memory. Reported-by:

Batman-adv could receive several payload broadcasts at the same time that would trigger access to the broadcast seqno sliding window to determine whether this is a new broadcast or not. If these incoming broadcasts are accessing the sliding window simultaneously it could be left in an inconsistent state. Therefore it is necessary to make sure this access is atomic. Reported-by:

bonding / alternating candidates need to be secured by rcu locks as well. This patch therefore converts the bonding list from a plain pointer list to a rcu securable lists and references the bonding candidates. Signed-off-by:

hardif_disable_interface() calls purge_orig_ref() to immediately free all neighbors associated with the interface that is going down. purge_orig_neighbors() checked if the interface status is IF_INACTIVE which is set to IF_NOT_IN_USE shortly before calling purge_orig_ref(). Signed-off-by: -

The only necessary parts are the src/dst addresses, the interface indexes, the TOS, and the mark. The rest is unnecessary bloat, which amounts to nearly 50 bytes on 64-bit. Signed-off-by: -

rt->rt_iif is only ever inspected on input routes, for example DCCP uses this to populate a route lookup flow key when generating replies to another packet. Therefore, setting it to anything other than zero on output routes makes no sense. Signed-off-by: -
