* cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg2008-02-291-120/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

* mac80211: add unified BSS configurationJohannes Berg2008-01-281-6/+6
| | | | | | | | | | | | | | | | | | | | | | 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 Berg2008-01-281-1/+1
| | | | | | | | | | 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 <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: dont use interface indices in driversJohannes Berg2008-01-281-30/+15
| | | | | | | | | | | | | | | | 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.

* mac80211: clean up eapol handling in TX pathJohannes Berg2008-01-281-17/+0
| | | | | | | | | | | | | | 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 <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: make ieee80211_iterate_active_interfaces not need rtnlJohannes Berg2008-01-281-3/+4
| | | | | | | | | | | | | | 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 <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: restructuring data Rx handlersRon Rindjunsky2008-01-281-13/+1
| | | | | | | | | | | | | | | | | | | | | | 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 <ron.rindjunsky@intel.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: provide interface iterator for driversJohannes Berg2008-01-281-0/+33
| | | | | | | | | | | | | | 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.

* [MAC80211]: remove turbo modesJohannes Berg2007-10-101-10/+1
| | | | | | | | | | | | | | | This patch removes all mention of the atheros turbo modes that can't possibly work properly anyway since in some places we don't check for them when we should. I have no idea what the iwlwifi drivers were doing with these but it can't possibly have been correct.

* [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-101-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

* [MAC80211]: improved short preamble handlingDaniel Drake2007-10-101-6/+31
| | | | | | | | | | | | | | | | | | | | | | | Similarly to CTS protection, whether short preambles are used for 802.11b transmissions should be a per-subif setting, not device global. For STAs, this patch makes short preamble handling automatic based on the ERP IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been restricted to AP-only subifs. ieee80211_txrx_data.short_preamble (an unused field) was removed. Unfortunately, some API changes were required for the following functions: - ieee80211_generic_frame_duration - ieee80211_rts_duration - ieee80211_ctstoself_duration - ieee80211_rts_get - ieee80211_ctstoself_get Affected drivers were updated accordingly.
