* 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.

* batman-adv: make the Distributed ARP Table vlan awareAntonio Quartulli2013-10-192-48/+107
| | | | | | | | | | | The same IP subnet can be used on different VLANs, therefore DAT has to differentiate whether the IP to resolve belongs to one or the other virtual LAN. To accomplish this task DAT has to deal with the VLAN tag and store it together with each ARP entry.

| | | | | | | | | | | | | | | | Remove the specialized code in __tcp_retransmit_skb() that tries to trim any ACKed payload preceding a FIN before we retransmit (this was added in 1999 in v2.2.3pre3).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | link_cmd_set_value() takes commands for link, bearer and media related configuration. Genereally the function returns 0 when a command is recognized, and -EINVAL when it is not. However, in the switch for link related commands it returns 0 even when the command is unrecognized. This will sometimes make it look as if a failed configuration command has been successful, but has otherwise no negative effects. We remove this anomaly by returning -EINVAL even for link commands. We also rework all three switches to make them conforming to common kernel coding style.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, rcv_msg() always returns zero on a packet delivery upcall from net_device. To make its behavior more compliant with the way this API should be used, we change this to let it return NET_RX_SUCCESS (which is zero anyway) when it is able to handle the packet, and NET_RX_DROP otherwise. The latter does not imply any functional change, it only enables the driver to keep more accurate statistics about the fate of delivered packets.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | tipc_block_bearer() currently takes a bearer name (const char*) as argument. This requires the function to make a lookup to find the pointer to the corresponding bearer struct. In the current code base this is not necessary, since the only two callers (tipc_continue(),recv_notification()) already have validated copies of this pointer, and hence can pass it directly in the function call. We change tipc_block_bearer() to directly take struct tipc_bearer* as argument instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TIPC 'bearer' exists as an abstract concept, while 'media' is deemed a specific implementation of a bearer, such as Ethernet or Infiniband media. When a component inside TIPC wants to control a specific media, it only needs to access the generic bearer API to achieve this. However, in the current media implementations, the 'bearer' name is also extensively used in media specific function and variable names. This may create confusion, so we choose to replace the term 'bearer' with 'media' in all function names, variable names, and prefixes where this is what really is meant. Note that this change is cosmetic only, and no runtime behaviour changes are made here.

Drivers for such devices were forced to re-assemble A-MSDUs which would then be eventually disassembled by mac80211. This could lead to CPU cache thrashing and poor performance. Since A-MSDU has a single sequence number all subframes share it. This was in conflict with retransmission/duplication recovery (IEEE802.11-2012: 9.3.2.10). Patch introduces a new flag that is meant to be set for all individually reported A-MSDU subframes except the last one. This ensures the last_seq_ctrl is updated after the last subframe is processed. If an A-MSDU is actually a duplicate transmission all reported subframes will be properly discarded.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IBSS members may not immediately be able to send out their beacon when performing CSA, therefore also send a CSA action frame.

| | | * | mac80211: add support for CSA in IBSS modeSimon Wunderlich2013-09-266-43/+480
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This function adds the channel switch announcement implementation for the IBSS code. It is triggered by userspace (mac80211/cfg) or by external channel switch announcement, which have to be adopted. Both CSAs in beacons and action frames are supported. As for AP mode, the channel switch is applied after some time. However in IBSS mode, the channel switch IEs are generated in the kernel.

| | | * | mac80211: split off ibss disconnectSimon Wunderlich2013-09-261-80/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IBSS CSA will require to disconnect if a channel switch fails, but mac80211 should search and re-connect after this disconnect. To allow such usage, split off the ibss disconnect process in a separate function which only performs the disconnect without overwriting nl80211-supplied parameters.
