* mac80211: dissolve pre-rx handlersJohannes Berg2008-02-293-62/+37
| | | | | | | | | These handlers do not really return a status and the compiler can do a much better job when they're simply static functions that it can inline if appropriate. Also makes the code shorter. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: A-MPDU Tx add session's and low level driver's APIRon Rindjunsky2008-02-291-2/+2
| | | | | | | | | | | | | | | | This patch adds the API for 3 stages in A-MPDU Tx session flow: - request mac80211 to start/stop A-MPDU Tx session for specific TID. such a request should be issued by a load aware element, either mac80211 itself or external element. - requests by mac80211 to low-level driver to start/stop Tx aggregation. notice that low level driver responds now with Starting Sequence Number. - async feedback by low-level to mac80211 to inform that HW is ready for next A-MPDU Tx state. Changes in API to Rx A-MPDU were also made, reflected in iwlwifi changes as well. Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: allow sending multicast frames through virtual portsJohannes Berg2008-02-291-6/+15
| | | | | | | | | | When reworking the port access control code, I forgot multicast frames and those are now always rejected because the destination station is not known. This changes the code to allow through multicast frames and also avoid the sta hash lookup (which is bound to fail) for them.

* mac80211: make alignment warning optionalJohannes Berg2008-02-012-0/+19
| | | | | | | | | | | | | Driver authors should be aware of the alignment requirements, but not everybody cares about the warning. This patch makes it depend on a new Kconfig symbol MAC80211_DEBUG_PACKET_ALIGNMENT which can be enabled regardless of MAC80211_DEBUG and is recommended for driver authors (only). This also restricts the warning to data packets so other packets need not be realigned to not trigger the warning. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: fix alignment warningJohannes Berg2008-02-011-13/+33
| | | | | | | | | | | | When I introduced the alignment warning I forgot the A-MSDU case which has a different requirement because each frame contains 14-byte 802.3 headers in front of the IP payload. This patch moves the alignment warning to a place where we know whether we're dealing with an A-MSDU frame and adjusts it accordingly.

| | | | | | | | | | | Convert packet schedulers to use the netlink API. Unfortunately a gradual conversion is not possible without breaking compilation in the middle or adding lots of casts, so this patch converts them all in one step.

* mac80211: fix RCU locking in __ieee80211_rx_handle_packetJohannes Berg2008-01-291-1/+0
| | | | | | | | | | | Commit c7a51bda ("mac80211: restructure __ieee80211_rx") extracted __ieee80211_rx_handle_packet out of __ieee80211_rx and hence changed the locking rules for __ieee80211_rx_handle_packet(), it is now invoked under RCU lock.

| | | | | | | | | | | | This patch assigns correct TID to frames transmitted between two stations in the same BSS in AP mode. The problem is that skb->protocol is not set to ETH_P_IP and it is wrong to use that field at this stage.

| | | | | | | | | | | | | | | Before calling update_beacon() mac80211 must initialize the control.vif pointer so it can be used by the driver to determine which interface is trying to send the beacon. v2: ieee80211_beacon_get() should also initialize the vif pointer since it can be called by mac80211 internally before calling config_interface().

* mac80211: add unified BSS configurationJohannes Berg2008-01-296-67/+77
| | | | | | | | | | | | | | | | | | | | | | 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.

* mac80211: move interface type to vif structureJohannes Berg2008-01-2912-117/+116
| | | | | | | | | | Drivers that support mixed AP/STA operation may well need to know the type of a virtual interface when iterating over them.

* mac80211: dont use interface indices in driversJohannes Berg2008-01-296-67/+73
| | | | | | | | | | | | | | | | 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 <johannes@sipsolutions.net> Signed-off-by: John W.

* rc80211_pid should respect fixed rates.Andrew Lutomirski2008-01-291-4/+8
| | | | | | | | | | | I would argue that mac80211 should handle fixed rates outside the rate control code, which would also allow them to take effect immediately instead of during the rate control callback, but this is pretty close to correct.

* mac80211: better rate control algorithm selectionJohannes Berg2008-01-297-65/+134
| | | | | | | | | | | | | | | | | | | | | | This patch changes mac80211's Kconfig/Makefile to: * select between the PID and the SIMPLE rate control algorithm as default * always allow tri-state for the rate control algorithms, building those that are selected 'y' into the mac80211 module (if that is a module, otherwise all into the kernel) * force the default rate control algorithm to be built into mac80211 It also makes both rate control algorithms proper modules again with MODULE_LICENSE etc. Only if EMBEDDED is the user allowed to select "NONE" as default which will cause no algorithm to be selected, this will work only when the driver brings one itself (e.g. iwlwifi drivers).

| | | | | | | | | | | | This patch handles the reordering of the Rx A-MPDU. This issue occurs when the sequence of the internal MPDUs is not in the right order. such a case can be encountered for example when some MPDUs from previous aggregations were recieved, while others failed, so current A-MPDU will contain a mix of re-transmited MPDUs and new ones.
