2014-07-21batman-adv: drop QinQ claim frames in bridge loop avoidanceSimon Wunderlich1-10/+34
Since bridge loop avoidance only supports untagged or simple 802.1q tagged VLAN claim frames, claim frames with stacked VLAN headers (QinQ) should be detected and dropped. Transporting the over the mesh may cause problems on the receivers, or create bogus entries in the local tt tables.

2014-03-22batman-adv: remove obsolete skb_reset_mac_header() in batadv_bla_tx()Linus Lüssing1-3/+0
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 this commit removes the according, now redundant, skb_reset_mac_header() call in batadv_bla_tx().

2014-03-22batman-adv: use vlan_/eth_hdr() instead of skb->data in interface_tx pathLinus Lüssing1-1/+1

2013-10-19batman-adv: make the backbone gw check VLAN specificAntonio Quartulli1-8/+11
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.

2013-10-19batman-adv: make the TT global purge routine VLAN specificAntonio Quartulli1-2/+2
Instead of unconditionally removing all the TT entries served by a given originator, make tt_global_orig_del() remove only entries matching a given VLAN identifier provided as argument. If such argument is negative all the global entries served by the originator are removed. This change is used into the BLA code to purge entries served by a newly discovered Backbone node, but limiting the operation only to those connected to the VLAN where the backbone has been discovered.

2013-10-12batman-adv: use htons when possibleAntonio Quartulli1-6/+6
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>

2013-08-10batman-adv: fix potential kernel paging errors for unicast transmissionsLinus Lüssing1-0/+2
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.

Conflicts: drivers/net/wireless/ath/ath9k/Kconfig drivers/net/xen-netback/netback.c net/batman-adv/bat_iv_ogm.c net/wireless/nl80211.c The ath9k Kconfig conflict was a change of a Kconfig option name right next to the deletion of another option. The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

2013-02-27hlist: drop the node parameter from iteratorsSasha Levin1-24/+15
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.

2012-07-06batman-adv: check incoming packet type for blaSimon Wunderlich1-4/+11
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.
