2014-03-22batman-adv: prefer ether_addr_copy to memcpyAntonio Quartulli1-4/+4
On some architectures ether_addr_copy() is slightly faster than memcpy() therefore use the former when possible. Signed-off-by: Antonio Quartulli <antonio@meshcoding.com> Signed-off-by: Marek Lindner <mareklindner@neomailbox.ch>
2014-03-22batman-adv: use vlan_/eth_hdr() instead of skb->data in interface_tx pathLinus Lüssing1-6/+5
Our .ndo_start_xmit handler (batadv_interface_tx()) can rely on having the skb mac header pointer set correctly since the following commit present in kernels >= 3.9: "net: reset mac header in dev_start_xmit()" (6d1ccff627) Therefore we can safely use eth_hdr() and vlan_eth_hdr() instead of skb->data now, which spares us some ugly type casts. At the same time set the mac_header in batadv_dat_snoop_incoming_arp_request() before sending the skb along the TX path.

2014-02-17batman-adv: fix potential kernel paging error for unicast transmissionsAntonio Quartulli1-2/+7
batadv_send_skb_prepare_unicast(_4addr) might reallocate the skb's data. If it does then our ethhdr pointer is not valid anymore in batadv_send_skb_unicast(), resulting in a kernel paging error. Fixing this by refetching the ethhdr pointer after the potential reallocation. Signed-off-by: Linus Lüssing <linus.luessing@web.de> Signed-off-by: Antonio Quartulli <antonio@meshcoding.com>

2014-01-12batman-adv: consider outgoing interface in OGM sendingSimon Wunderlich1-5/+14
The current OGM sending an aggregation functionality decides on which interfaces a packet should be sent when it parses the forward packet struct. However, with the network wide multi interface optimization the outgoing interface is decided by the OGM processing function. This is reflected by moving the decision in the OGM processing function and add the outgoing interface in the forwarding packet struct. This practically implies that an OGM may be added multiple times (once per outgoing interface), and this also affects aggregation which needs to consider the outgoing interface as well.

2014-01-08batman-adv: send every DHCP packet as bat-unicastAntonio Quartulli1-3/+13
In different situations it is possible that the DHCP server or client uses broadcast Ethernet frames to send messages to each other. The GW component in batman-adv takes care of using bat-unicast packets to bring broadcast DHCP Discover/Requests to the "best" server. On the way back the DHCP server usually sends unicasts, but upon client request it may decide to use broadcasts as well. This patch improves the GW component so that it now snoops and sends as unicast all the DHCP packets, no matter if they were generated by a DHCP server or client.

2013-10-19batman-adv: refine API calls for unicast transmissions of SKBsLinus Lüssing1-20/+67
With this patch the functions batadv_send_skb_unicast() and batadv_send_skb_unicast_4addr() are further refined into batadv_send_skb_via_tt(), batadv_send_skb_via_tt_4addr() and batadv_send_skb_via_gw(). 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.

2013-10-12batman-adv: use htons when possibleAntonio Quartulli1-2/+2
When comparing a network ordered value with a constant, it is better to convert the constant at compile time by means of htons() instead of converting the value at runtime using ntohs(). This refactoring may slightly improve the code performance. Moreover substitute __constant_htons() with htons() since the latter increase readability and it is smart enough to be as efficient as the former Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Acked-by: Simon Wunderlich <siwu@hrz.tu-chemnitz.de>

2013-08-28batman-adv: set skb priority according to contentSimon Wunderlich1-1/+0
The skb priority field may help the wireless driver to choose the right queue (e.g. WMM queues). This should be set in batman-adv, as this information is only available here. This patch adds support for IPv4/IPv6 DS fields and VLAN PCP. Note that only VLAN PCP is used if a VLAN header is present. Also initially set TC_PRIO_CONTROL only for self-generated packets, and keep the priority set by higher layers.

While it makes sense to send each broadcast thrice on 802.11 (WLAN) interfaces as broadcasts are often unreliable on these, there is no reason to do so on other interface types.

To be able to decode a network coded packet, a node must already know one of the two coded packets. This is done by buffering skbs before transmission and buffering packets sniffed with promiscuous mode from other hosts. Packets are kept in a buffer similar to the one with forward-skbs: A hash table, where each entry, which corresponds to a src-dst pair, has a linked list packets.

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin1-3/+3
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually.

2012-11-21batman-adv: Add wrapper to look up neighbor and send skbMartin Hundebøll1-0/+33
By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate code that looks up the next hop and then calls batadv_send_skb_packet(). Furthermore, this prepares the upcoming new implementation of fragmentation, which requires the next hop to route packets. Please note that this doesn't entirely remove the next-hop lookup in routing.c and unicast.c, since it is used by the current fragmentation code. Also note that the next-hop info is removed from debug messages in translation-table.c, since it is looked up elsewhere.

2012-11-07batman-adv: Distributed ARP Table - add snooping functions for ARP messagesAntonio Quartulli1-0/+4
In case of an ARP message going in or out the soft_iface, it is intercepted and a special action is performed. In particular the DHT helper functions previously implemented are used to store all the ARP entries belonging to the network in order to provide a fast and unicast lookup instead of the classic broadcast flooding mechanism. Each node stores the entries it is responsible for (following the DHT rules) in its soft_iface ARP table. This makes it possible to reuse the kernel data structures and functions for ARP management.
