2008-08-18mac80211: update new sta's rx timestampRon Rindjunsky1-0/+2

2008-08-07mac80211: keep mesh ifaces in allmulti modeLuis Carlos Cobo1-1/+7
Currently a mesh node will not forward a multicast frame if it is not subscribed to the specific multicast address. This patch addresses the issue and fixes mesh multicast forwarding.

2008-08-07mac80211: fix use of skb->cb for mesh forwardingLuis Carlos Cobo5-90/+106
Now we deal with mesh forwarding before the 802.11->802.3 conversion, thus eliminating a few unnecessary steps. The next hop lookup is called from ieee80211_master_start_xmit() instead of subif_start_xmit(). Until the next hop is found, RA in the frame will be all zeroes for frames originating from the device. For forwarded frames, RA will contain the TA of the received frame, which will be necessary to send a path error if a next hop is not found.

2008-08-04mac80211: automatic IBSS channel selectionDaniel Drake1-4/+16
When joining an ad-hoc network, the user is currently required to specify the channel. The network will not be joined otherwise, unless it happens to be sitting on the currently active channel.

2008-07-29mac80211: fix cfg80211 hooks for master interfaceJohannes Berg1-15/+88
The master interface is a virtual interface that is registered to mac80211, changing that does not seem like a good idea at the moment. However, since it has no sdata, we cannot accept any configuration for it. This patch makes the cfg80211 hooks reject any such attempt.

2008-07-29mac80211: partially fix skb->cb useJohannes Berg4-39/+27
This patch fixes mac80211 to not use the skb->cb over the queue step from virtual interfaces to the master. The patch also, for now, disables aggregation because that would still require requeuing, will fix that in a separate patch. There are two other places (software requeue and powersaving stations) where requeue can happen, but that is not currently used by any drivers/not possible to use respectively.

2008-07-29mac80211: append CONFIG_ to MAC80211_VERBOSE_PS_DEBUG in net/mac80211/tx.c.Rami Rosen1-3/+3
In net/mac80211/tx.c, there are some #ifdef which checks MAC80211_VERBOSE_PS_DEBUG (which in fact is never set) instead of CONFIG_MAC80211_VERBOSE_PS_DEBUG, as should be.

2008-07-17netdev: Allocate multiple queues for TX.David S. Miller2-8/+8
alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

2008-07-15netdev: Do not use TX lock to protect address lists.David S. Miller2-12/+6

2008-07-15netdev: Add netdev->addr_list_lock protection.David S. Miller2-0/+8
Add netif_addr_{lock,unlock}{,_bh}() helpers. Use them to protect operations that operate on or read the network device unicast and multicast address lists. Also use them in cases where the code simply wants to block calls into the driver's ->set_rx_mode() and ->set_multicast_list() methods. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-14mac80211: fix TX sequence numbersJohannes Berg4-31/+52
This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.

2008-07-14mac80211: revamp beacon configurationJohannes Berg6-121/+95
This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

2008-07-14mac80211: push interface checks downJohannes Berg4-16/+25

2008-07-14mac80211: make master netdev handling saneJohannes Berg12-217/+153
Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

2008-07-09rc80211_pid: Fix fast_start parameter handlingMattias Nissler2-23/+13
This removes the fast_start parameter from the rc_pid parameters information and instead uses the parameter macro when initializing the rc_pid state. Since the parameter is only used on initialization, there is no point of making exporting it via debugfs. This also fixes uninitialized memory references to the fast_start and norm_offset parameters detected by the kmemcheck utility. Thanks to Vegard Nossum for reporting the bug.

2008-07-08netdev: Move queue_lock into struct netdev_queue.David S. Miller2-6/+6
The lock is now an attribute of the device queue. One thing to notice is that "suspicious" places emerge which will need specific training about multiple queue handling.

2008-07-08pkt_sched: Remove 'dev' member of struct Qdisc.David S. Miller1-14/+14
It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-08netdev: Create netdev_queue abstraction.David S. Miller1-2/+4
A netdev_queue is an entity managed by a qdisc. Currently there is one RX and one TX queue, and a netdev_queue merely contains a backpointer to the net_device. The Qdisc struct is augmented with a netdev_queue pointer as well. Eventually the 'dev' Qdisc member will go away and we will have the resulting hierarchy: net_device --> netdev_queue --> Qdisc Also, qdisc_alloc() and qdisc_create_dflt() now take a netdev_queue pointer argument.
