* libipw: initiate cfg80211 API conversion (v2)John W. Linville2009-11-234-36/+161
| | | | | | | | | | | | | | | | Initiate the conversion of libipw to the new cfg80211 configuration API. For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone. Eventually migrate it to cfg80211 when the add/del/change_virtual_intf methods are implemented. (v2: Fix unconditional wiphy_unregister in libipw which was causing problems for ipw2100, somewhat based on prior attempted fix by Zhu Yi <yi.zhu@intel.com>. Previously both original version of this patch and Zhu Yi's fix attempt were reverted due to discovery of regressions. -- JWL) Signed-off-by: John W. Linville <linville@tuxdriver.com>

* mac80211: avoid spurious deauth frames/messagesJohannes Berg2009-11-193-11/+54
| | | | | | | | | | | | | | | | | | | With WEXT, it happens frequently that the SME requests an authentication but then deauthenticates right away because some new parameters came along. Every time this happens we print a deauth message and send a deauth frame, but both of that is rather confusing. Avoid it by aborting the authentication process silently, and telling cfg80211 about that. The patch looks larger than it really is: __cfg80211_auth_remove() is split out from cfg80211_send_auth_timeout(), there's no new code except __cfg80211_auth_canceled() (a one-liner) and the mac80211 bits (7 new lines of code).

* mac80211: request TX status where neededJohannes Berg2009-11-197-14/+23
| | | | | | | | | | | | | | | | | | | | | | | | Right now all frames mac80211 hands to the driver have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to request TX status. This isn't really necessary, only the injected frames need TX status (the latter for hostapd) so move setting this flag. The rate control algorithms also need TX status, but they don't require it. Also, rt2x00 uses that bit for its own purposes and seems to require it being set for all frames, but that can be fixed in rt2x00. This doesn't really change anything for any drivers but in the future drivers using hw-rate control may opt to not report TX status for frames that don't have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

* cfg80211: disallow bridging managed/adhoc interfacesJohannes Berg2009-11-195-4/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A number of people have tried to add a wireless interface (in managed mode) to a bridge and then complained that it doesn't work. It cannot work, however, because in 802.11 networks all packets need to be acknowledged and as such need to be sent to the right address. Promiscuous doesn't help here. The wireless address format used for these links has only space for three addresses, the * transmitter, which must be equal to the sender (origin) * receiver (on the wireless medium), which is the AP in the case of managed mode * the recipient (destination), which is on the APs local network segment In an IBSS, it is similar, but the receiver and recipient must match and the third address is used as the BSSID. To avoid such mistakes in the future, disallow adding a wireless interface to a bridge. Felix has recently added a four-address mode to the AP and client side that can be used (after negotiating that it is possible, which must happen out-of-band by setting up both sides) for bridging, so allow that case.

* cfg80211: introduce capability for 4addr modeJohannes Berg2009-11-199-30/+82
| | | | | | | | | | | | | | | | It's very likely that not many devices will support four-address mode in station or AP mode so introduce capability bits for both modes, set them in mac80211 and check them when userspace tries to use the mode. Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly. However, keep track of use_4addr for station mode in mac80211 to avoid all the derefs. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

The current code does not enforce them and/or incorrectly enforces them.

* cfg80211: Allow reassociation in associated stateJouni Malinen2009-11-181-2/+18
| | | | | | | | | | | | | | | cfg80211 rejects all association requests when in associated state. This prevents clean roaming within an ESS since one would first need to disassociate before being able to request reassociation. Accept the reassociation request and let the old association to be dropped when the new one is completed. This fixes nl80211-based roaming with the current snapshot version of wpa_supplicant (that has code for requesting reassociation explicitly withthe previous BSSID attribute).

* mac80211: make software rate control optionalJohannes Berg2009-11-186-13/+56
| | | | | | | | | | | | | | | | | Some devices implement the entire rate control in firmware in some way, like wl1271 or like iwlwifi which does some things in software but not a lot. Therefore generic software rate control is rather useless for them and just adds avoidable overhead to the transmit path. It's fairly simple to let drivers indicate that they do not need rate control, but they need to fulfil a number of conditions that we encode in WARN_ONs.

* ath9k: Remove a few unused functionsSujith2009-11-184-169/+0
| | | | | | | | | | | ATH9K_ANT_VARIABLE is the default diversity control used. Consequently ath9k_hw_decrease_chain_power() does nothing. ath9k_hw_setantennaswitch() is unused too. Also, gbeacon_rate is unused. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* ath9k: Cleanup bss_info_changed callbackSujith2009-11-181-77/+37
| | | | | | | | | | | | | | | | | | | | | | | | * Remove a code chunk dealing with operating mode changes. As noted, all such policy changes are to be done in add_interface. * Remove pointless check for empty BSSID. Also, remove mode checks - mac80211 does all the needed checks. * Handle enabling/disabling beacon transmission properly. * Handle beacon interval changes for AP mode. The original code depended on config_interface() to update the HW TSF. Since that callback has been removed, handle it properly. * Remove unneeded code dealing with key/privacy. * Set the chainmasks to 1x1 for IBSS when the BSSID is set. This was happening uncondionally before. Signed-off-by: Sujith <Sujith.Manoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* ath9k: get rid of tx_info_privFelix Fietkau2009-11-186-97/+83
| | | | | | | | | This patch removes the need for separately allocated private tx info data in ath9k and brings the driver one small step closer to using the mac80211 rate control API properly. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
