batman-adv: Remove old fragmentation code

2013-10-12T09:58:33+00:00

Remove the existing fragmentation code before adding the new version and delete unicast.{h,c}. batadv_unicast_send_skb() is moved to send.c and renamed to batadv_send_skb_unicast(). fragmentation entry in sysfs (bat_priv->fragmentation) is kept for use in the new fragmentation code. BATADV_UNICAST_FRAG packet type is renamed to BATADV_FRAG for use in the new fragmentation code. Signed-off-by: Martin Hundebøll Signed-off-by: Marek Lindner Signed-off-by: Antonio Quartulli

batman-adv: set skb priority according to content

2013-08-28T09:31:50+00:00

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.

batman-adv: check return type of unicast packet preparations

2013-08-17T18:02:32+00:00

batadv_unicast(_4addr)_prepare_skb might reallocate the skb's data. And if it tries to do so then this can potentially fail. We shouldn't continue working on this skb in such a case.

batman-adv: fix potential kernel paging errors for unicast transmissions

2013-08-10T20:55:42+00:00

There are several functions which might reallocate skb data. Currently some places keep reusing their old ethhdr pointer regardless of whether they became invalid after such a reallocation or not. This potentially leads to kernel paging errors. This patch fixes these by refetching the ethdr pointer after the potential reallocations.

batman-adv: Move call to batadv_nc_skb_forward() from routing.c to send.c

2013-05-29T00:44:55+00:00

The call to batadv_nc_skb_forward() fits better in batadv_send_skb_to_orig(), as this is where the actual next hop is looked up. To let the caller of batadv_send_skb_to_orig() know wether the skb is transmitted, buffered or failed, the return value is changed from boolean to int.

batman-adv: don't use !! in bool conversion

2013-03-13T21:53:48+00:00

In C standard any expression different from 0 will be converted to 'true' when casting to bool (whatever is the length of the value). Therefore all the "!!" conversions can be removed. Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner

batman-adv: Add wrapper to look up neighbor and send skb

2012-11-21T11:34:50+00:00

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.

batman-adv: Distributed ARP Table - create DHT helper functions

2012-11-07T19:00:19+00:00

Add all the relevant functions in order to manage a Distributed Hash Table over the B.A.T.M.A.N.-adv network. It will later be used to store several ARP entries and implement DAT (Distributed ARP Table) Signed-off-by: Antonio Quartulli
