* nl80211: Add MLME primitives to support external SMEJouni Malinen2009-03-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds new nl80211 commands to allow user space to request authentication and association (and also deauthentication and disassociation). The commands are structured to allow separate authentication and association steps, i.e., the interface between kernel and user space is similar to the MLME SAP interface in IEEE 802.11 standard and an user space application takes the role of the SME. The patch introduces MLME-AUTHENTICATE.request, MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and MLME-DISASSOCIATE.request primitives. The authentication and association commands request the actual operations in two steps (assuming the driver supports this; if not, separate authentication step is skipped; this could end up being a separate "connect" command). The initial implementation for mac80211 uses the current net/mac80211/mlme.c for actual sending and processing of management frames and the new nl80211 commands will just stop the current state machine from moving automatically from authentication to association. Future cleanup may move more of the MLME operations into cfg80211. The goal of this design is to provide more control of authentication and association process to user space without having to move the full MLME implementation. This should be enough to allow IEEE 802.11r FT protocol and 802.11s SAE authentication to be implemented. Obviously, this will also bring the extra benefit of not having to use WEXT for association requests with mac80211. An example implementation of a user space SME using the new nl80211 commands is available for wpa_supplicant. This patch is enough to get IEEE 802.11r FT protocol working with over-the-air mechanism (over-the-DS will need additional MLME primitives for handling the FT Action frames).

* mac80211: Fix MFP Association Comeback to use Timeout Interval IEJouni Malinen2009-01-29
| | | | | | | | | | The separate Association Comeback Time IE was removed from IEEE 802.11w and the Timeout Interval IE (from IEEE 802.11r) is used instead. The editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but still, the use of Timeout Interval IE is the expected mechanism.

* mac80211: 802.11w - Implement Association Comeback processingJouni Malinen2009-01-29
| | | | | | | | | | | | | | | | | When MFP is enabled, the AP does not allow a STA to associate if an existing security association exists without first going through SA Query process. When this happens, the association request is denied with a new status code ("temporarily rejected") ans Association Comeback IE is used to notify when the association may be tried again (i.e., when the SA Query procedure has timed out). Use the comeback time to update the mac80211 client MLME timer for next association attempt to minimize waiting time if association is temporarily rejected.

* cfg80211/mac80211: Add 802.11d supportLuis R. Rodriguez2008-11-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds country IE parsing to mac80211 and enables its usage within the new regulatory infrastructure in cfg80211. We parse the country IEs only on management beacons for the BSSID you are associated to and disregard the IEs when the country and environment (indoor, outdoor, any) matches the already processed country IE. To avoid following misinformed or outdated APs we build and use a regulatory domain out of the intersection between what the AP provides us on the country IE and what CRDA is aware is allowed on the same country. A secondary device is allowed to follow only the same country IE as it make no sense for two devices on a system to be in two different countries. In the case the AP is using country IEs for an incorrect country the user may help compliance further by setting the regulatory domain before or after the IE is parsed and in that case another intersection will be performed. CONFIG_WIRELESS_OLD_REGULATORY is supported but requires CRDA present. Signed-off-by: Luis R.

* mac80211_hwsim: Add support for client PS modeJouni Malinen2008-11-10
| | | | | | | | | | | | | | | | | | | | | | | | This introduces a debugfs file (ieee80211/phy#/hwsim/ps) that can be used to force a simulated radio into power save mode. Following values can be written into this file to change PS mode: 0 = power save disabled (constantly awake) 1 = power save enabled (drop all frames; do not send PS-Poll) 2 = power save enabled (send PS-Poll frames automatically to receive buffered unicast frames); not yet fully implemented 3 = manual PS-Poll trigger (send a single PS-Poll frame) Two different behavior for power save mode processing can be tested: - move between modes 1 and 0 (i.e., receive all buffered frames at a time) - move to mode 1 and use manual PS-Poll frames (write 3 to the 'ps' debugfs file) to fetch power save buffered frames one at a time Mode 2 (automatic PS-Poll) does not yet parse Beacon frames, but eventually, it should take a look at TIM IE and send PS-Poll if a traffic bit is set for our AID.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | A few general categories: 1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de in the same order as the fctl defines: A combined _has_a4 was also added to test when both FROMDS and TODS are set. 2) ieee80211_is_* is meant to test whether the frame control is of a certain ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres which also test a subset of the stype space. When testing for a particular stype applicable only to one ftype, functions like ieee80211_is_ack have been added. Note that the ftype is also being checked in these helpers. They have been added for all mgmt and ctl stypes in the same order as the STYPE defines. 3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl. The intel wireless drivers had helpers that used this namespace, convert the all to use the new helpers and remove the byteshifting as they were defined in cpu-order rather than little-endian.
