* batman-adv: generalize batman-adv icmp packet handlingSimon Wunderlich2013-10-235-97/+157
| | | | | | | | | | | | | | | | Instead of handling icmp packets only up to length of icmp_packet_rr, the code should handle any icmp length size. Therefore the length truncating is moved to when the packet is actually sent to userspace (this does not support lengths longer than icmp_packet_rr yet). Longer packets are forwarded without truncating. This patch also cleans up some parts where the icmp header struct could be used instead of other icmp_packet(_rr) structs to make the code more readable.

* batman-adv: include the sync-flags when compute the global/local table CRCAntonio Quartulli2013-10-233-2/+28
| | | | | | | | | | | | | | | | | | | | | | Flags covered by TT_SYNC_MASK are kept in sync among the nodes in the network and therefore they have to be considered while computing the global/local table CRC. In this way a generic originator is able to understand if its table contains the correct flags or not. Bits from 4 to 7 in the TT flags fields are now reserved for "synchronized" flags only. This allows future developers to add more flags of this type without breaking compatibility. It's important to note that not all the remote TT flags are synchronised. This comes from the fact that some flags are used to inject an information once only.

* batman-adv: improve the TT component to support runtime flag changesAntonio Quartulli2013-10-232-1/+30
| | | | | | | | | | | | | | | | Some flags (i.e. the WIFI flag) may change after that the related client has already been announced. However it is useful to informa the rest of the network about this change. Add a runtime-flag-switch detection mechanism and re-announce the related TT entry to advertise the new flag value. This mechanism can be easily exploited by future flags that may need the same treatment.

| | | | | | | | | | | | Upcoming changes need to perform other checks on the incoming net_device struct. To avoid performing dev_get_by_index() for each and every check, it is better to move it outside of is_wifi_iface() and search the netdev object once only.

* batman-adv: limit local translation table max sizeMarek Lindner2013-10-235-36/+173
| | | | | | | | | | | | | | | The local translation table size is limited by what can be transferred from one node to another via a full table request. The number of entries fitting into a full table request depend on whether the fragmentation is enabled or not. Therefore this patch introduces a max table size check and refuses to add more local clients when that size is reached. Moreover, if the max full table packet size changes (MTU change or fragmentation is disabled) the local table is downsized instantaneously.

* batman-adv: provide orig_node routing APIAntonio Quartulli2013-10-233-88/+151
| | | | | | | | | | | | | | | | | | | | | Some operations executed on an orig_node depends on the current routing algorithm being used. To easily make this mechanism routing algorithm agnostic add a orig_node specific API that each algorithm can populate with its own routines. Such routines are then invoked by the code when needed, without knowing which routing algorithm is currently in use With this patch 3 API functions are added: - orig_free (to free routing depending internal structs) - orig_add_if (to change the inner state of an orig_node when a new hard interface is added) - orig_del_if (to change the inner state of an orig_node when an hard interface is removed) Signed-off-by: Antonio Quartulli <antonio@open-mesh.com> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de>

* batman-adv: make the backbone gw check VLAN specificAntonio Quartulli2013-10-193-43/+27
| | | | | | | | | | | | | | | | | | | | | The backbone gw check has to be VLAN specific so that code using it can specify VID where the check has to be done. In the TT code, the check has been moved into the tt_global_add() function so that it can be performed on a per-entry basis instead of ignoring all the TT data received from another backbone node. Only TT global entries belonging to the VLAN where the backbone node is connected to are skipped. All the other spots where the TT code was checking whether a node is a backbone have been removed. Moreover, batadv_bla_is_backbone_gw_orig() now returns bool since it used to return only 1 or 0.

* batman-adv: make the TT CRC logic VLAN specificAntonio Quartulli2013-10-195-157/+730
| | | | | | | | | | | | | | | | | | | | | | | | | | | This change allows nodes to handle the TT table on a per-VLAN basis. This is needed because nodes may have to store only some of the global entries advertised by another node. In this scenario such nodes would re-create only a partial global table and would not be able to compute a correct CRC anymore. This patch splits the logic and introduces one CRC per VLAN. In this way a node fetching only some entries belonging to some VLANs is still able to compute the needed CRCs and still check the table correctness. With this patch the shape of the TVLV-TT is changed too because now a node needs to advertise all the CRCs of all the VLANs that it is wired to. The debug output of the local Translation Table now shows the CRC along with each entry since there is not a common value for the entire table anymore.

* batman-adv: lock around TT operations to avoid sending inconsistent dataAntonio Quartulli2013-10-194-4/+34
| | | | | | | | | | | | | | | | | | | | A TT response may be prepared and sent while the local or global translation table is getting updated. The worst case is when one of the tables is accessed after its content has been recently updated but the metadata (TTVN/CRC) has not yet. In this case the reader will get a table content which does not match the TTVN/CRC. This will lead to an inconsistent state and so to a TT recovery. To avoid entering this situation, put a lock around those TT operations recomputing the metadata and around the TT Response creation (the latter is the only reader that accesses the metadata together with the table).

This way we avoid any "guessing" about where to send a packet in the unicast forwarding methods and let the callers decide. This is going to be useful for the upcoming multicast related patches in particular. Further, the return values were polished a little to use the more appropriate NET_XMIT_* defines.

* batman-adv: add sysfs framework for VLANAntonio Quartulli2013-10-194-3/+198
| | | | | | | | | | | | | | | | | | | Each VLAN can now have its own set of attributes which are exported through a new subfolder in the sysfs tree. Each VLAN created on top of a soft_iface will have its own subfolder. The subfolder is named "vlan%VID" and it is created inside the "mesh" sysfs folder belonging to batman-adv. Attributes corresponding to the untagged LAN are stored in the root sysfs folder as before.

* batman-adv: add per VLAN interface attribute frameworkAntonio Quartulli2013-10-195-3/+197
| | | | | | | | | | | | | | | | | | | Since batman-adv is now fully VLAN-aware, a proper framework able to handle per-vlan-interface attributes is needed. Those attributes will affect the associated VLAN interface only, rather than the real soft_iface (which would result in every vlan interface having the same attribute configuration). To make the code simpler and easier to extend, attributes associated to the standalone soft_iface are now treated like belonging to yet another vlan having a special vid. This vid is different from the others because it is made up by all zeros and the VLAN_HAS_TAG bit is not set.
