2012-09-19batman-adv: make batadv_test_bit() return 0 or 1 onlyLinus Lüssing1-3/+3
On some architectures test_bit() can return other values than 0 or 1: With a generic x86 OpenWrt image in a kvm setup (batadv_)test_bit() frequently returns -1 for me, leading to batadv_iv_ogm_update_seqnos() wrongly signaling a protected seqno window. This patch tries to fix this issue by making batadv_test_bit() return 0 or 1 only.

2012-08-08batman-adv: Fix mem leak in the batadv_tt_local_event() functionJesper Juhl1-0/+1
Memory is allocated for 'tt_change_node' with kmalloc(). 'tt_change_node' may go out of scope really being used for anything (except have a few members initialized) if we hit the 'del:' label. This patch makes sure we free the memory in that case. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Acked-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: David S.

2012-07-06batman-adv: check incoming packet type for blaSimon Wunderlich3-7/+19
If the gateway functionality is used, some broadcast packets (DHCP requests) may be transmitted as unicast packets. As the bridge loop avoidance code now only considers the payload Ethernet destination, it may drop the DHCP request for clients which are claimed by other backbone gateways, because it falsely infers from the broadcast address that the right backbone gateway should havehandled the broadcast. Fix this by checking and delegating the batman-adv packet type used for transmission.

2012-07-01batman-adv: Remove bat_ prefix from bat_{debugfs, sysfs}.{c, h}Sven Eckelmann9-10/+10
The "bat_" prefix in the source files implementing the batman-adv sysfs and debugfs interface doesn't have a special meaning and are only used by these files and files that implement the actual B.A.T.M.A.N. path finding algorithm. The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.

2012-06-28batman-adv: clear ADD+DEL (and viceversa) events in the same orig-intervalAntonio Quartulli1-3/+37
During an OGM-interval (time between two different OGM sendings) the same client could roam away and then roam back to us. In this case the node would add two events to the events list (that is going to be sent appended to the next OGM). A DEL one and an ADD one. Obviously they will only increase the overhead (either in the air and on the receiver side) and eventually trigger wrong states/events without producing any real effect. For this reason we can safely delete any ADD event with its related DEL one. Signed-off-by: Antonio Quartulli <ordex@autistici.org> Signed-off-by: Sven Eckelmann <sven@narfation.org>
