No need to check the support of mergeable buffer inside the recevie loop as the whole handle_rx()_xx is in the read critical region. So this patch move it ahead of the receiving loop. Signed-off-by:

copy_from_user is pretty high on perf top profile, replacing it with __copy_from_user helps. It's also safe because we do access_ok checks during setup. Signed-off-by: -

When doing output route lookups, we have to select the source address if the user has not specified an explicit one. First, if the route has an explicit preferred source address specified, then we use that. Otherwise we search the route's outgoing interface for a suitable address. This search can be precomputed and cached at route insertion time. The only missing part is that we have to refresh this precomputed value any time addresses are added or removed from the interface, and this is accomplished by fib_update_nh_saddrs().

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: -

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:

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().

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:
