mac80211: add unified BSS configuration

2008-01-28T23:09:43Z

This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change. Signed-off-by: Ron Rindjunsky Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: move interface type to vif structure

2008-01-28T23:09:37Z

Drivers that support mixed AP/STA operation may well need to know the type of a virtual interface when iterating over them. The easiest way to support that is to move the interface type variable into the vif structure. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville

mac80211: dont use interface indices in drivers

2008-01-28T23:09:36Z

This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg Signed-off-by: John W.

mac80211: clean up eapol handling in TX path

2008-01-28T22:59:46Z

The previous patch left only one user of the ieee80211_is_eapol() function and that user can be eliminated easily by introducing a new "frame is EAPOL" flag to handle the frame specially (we already have this information) instead of doing the (expensive) ieee80211_is_eapol() all the time. Also, allow unencrypted frames to be sent when they are injected. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S. Miller

mac80211: pass in PS_POLL frames

2008-01-28T22:59:16Z

This patch fixes should_drop_frame function to pass in ps poll control frames required for power save functioanlity. Interface types that do not have interest for PS POLL frames now drop it in handler. Signed-off-by: Ron Rindjunsky Acked-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S.

mac80211: make ieee80211_iterate_active_interfaces not need rtnl

2008-01-28T22:55:28Z

Interface iteration in mac80211 can be done without holding any locks because I converted it to RCU. Initially, I thought this wouldn't be needed for ieee80211_iterate_active_interfaces but it's turning out that multi-BSS AP support can be much simpler in a driver if ieee80211_iterate_active_interfaces can be called without holding locks. This converts it to use RCU, it adds a requirement that the callback it invokes cannot sleep. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S. Miller

mac80211: restructuring data Rx handlers

2008-01-28T22:55:27Z

This patch restructures the Rx handlers chain by incorporating previously handlers ieee80211_rx_h_802_1x_pae and ieee80211_rx_h_drop_unencrypted into ieee80211_rx_h_data, already in 802.3 form. this scheme follows more precisely after the IEEE802.11 data plane archituecture, and will prevent code duplication to IEEE8021.11n A-MSDU handler. added function: - ieee80211_data_to_8023: transfering 802.11 data frames to 802.3 frame - ieee80211_deliver_skb: delivering the 802.3 frames to upper stack eliminated handlers: - ieee80211_rx_h_drop_unencrypted: now function ieee80211_drop_unencrypted - ieee80211_rx_h_802_1x_pae: now function ieee80211_802_1x_pae changed handlers: - ieee80211_rx_h_data: now contains calls to four above function Signed-off-by: Ron Rindjunsky Acked-by: Johannes Berg Signed-off-by: John W.

mac80211: provide interface iterator for drivers

2008-01-28T22:54:37Z

Sometimes drivers need to know which interfaces are associated with their hardware. Rather than forcing those drivers to keep track of the interfaces that were added, this adds an iteration function to mac80211. As it is intended to be used from the interface add/remove callbacks, the iteration function may currently only be called under RTNL. Signed-off-by: Johannes Berg Signed-off-by: John W.

[MAC80211]: fix warnings introduced by the doc patches

2007-10-10T23:52:30Z

This fixes a warning about NUM_IEEE80211_MODES missing in a switch statement. Intentionally do not add a default case so we get warnings at these places if we need to add new modes. Signed-off-by: Johannes Berg Signed-off-by: Michael Wu Signed-off-by: John W. Linville Signed-off-by: David S. Miller
