[batman-adv] master: batman-adv: (style) fix for switched vid-ifiindex parameter order (cc14598)
by postmaster＠open-mesh.org
Repository : ssh://git@open-mesh.org/batman-adv
On branch : master
>---------------------------------------------------------------
commit cc14598eabfbe26e2cb62a435da786e5c6f5fd4b
Author: Linus Lüssing <linus.luessing(a)web.de>
Date: Fri Jun 14 20:04:09 2013 +0200
batman-adv: (style) fix for switched vid-ifiindex parameter order
batadv_tt_local_add() first takes the vid and then the interface index
parameter. One of these calls had the order switched.
However in this case it is not a functional, but just a style fix
because at the moment BATADV_NO_FLAGS is equal to BATADV_NULL_IFINDEX.
Introduced by 580d7919f19e4f73ccd79e82a532af2bdc638042

tagged by Antonio Quartulli

- Shortlog ------------------------------------------------------------
Included change:
- fix "rtnl locked" concurrent executions by using rtnl_lock instead of
rtnl_trylock. This fix enables batman-adv initialisation to do not fail just
because somewhere else in the system another code path is holding the rtnl
lock. It is easy to see the problem when batman-adv is trying to start
together with other networking components.
- fix the routing protocol forwarding policy by enhancing the duplicate control
packet detection. When the right circumstances trigger the issue, some nodes in
the network become totally unreachable, so breaking the mesh connectivity.
- fix the Bridge Loop Avoidance component by not running the originator address
change handling routine when the component is disabled. The routine was
generating useless packets that were sent over the network.

batctl: add the VLAN ID attribute to the TT entry
To make the translation table code VLAN-aware, each entry
must carry the VLAN ID which it belongs to. This patch adds
such attribute to the related TT structures.

batman-adv: make the Distributed ARP Table vlan aware
The same IP subnet can be used on different VLANs, therefore
DAT has to differentiate whether the IP to resolve belongs
to one or the other virtual LAN.
To accomplish this task DAT has to deal with the VLAN tag
and store it together with each ARP entry.

commit 4af2a1b2bf1354aa8b3683c9ac6a475d5a8f21ee

batman-adv: use vid when computing local and global TT CRC
now that each TT entry is characterised by a VLAN ID, the
latter has to be taken into consideration when computing the
local/global table CRC as it would be theoretically possible
to have the same client in two different VLANs

+ * This function computes the checksum for the global table corresponding to a

+ * the CRC32C function affects the result and since every node in the network
+ * probably sorts the clients differently, the hash function cannot be directly
+ * computed over the entire table. Hence the CRC32C is used only on
+ * the single client entry, while all the results are then xor'ed together
+ * because the XOR operation can combine them all while trying to reduce the
