2007-07-12[PATCH] mac80211: improved 802.11g CTS protectionDaniel Drake
Currently, CTS protection is partially implemented twice: 1. via prism2 ioctls, only used by hostapd 2. via STA beacon parsing, recorded in sta.use_protection but never used (other than printed in debugfs) Protection control should be implemented on a per-subif basis. For example, a single physical device may be running a soft AP on one channel, and a STA on another. The AP interface should use protection based on what hostapd told it, and the STA interface should use protection based on beacon parsing. These should operate independantly: one subif using protection should not influence the other. To implement this, I moved the use_protection flag into ieee80211_sub_if_data and removed the device-global cts_protect_erp_frames flag. I also made the PRISM2_PARAM_CTS_PROTECT_ERP_FRAMES write operation only available for AP interfaces, to avoid any possibility of the user messing with the behaviour of a STA.

2007-07-12[PATCH] mac80211: ERP IE handling improvementsDaniel Drake
The "protection needed" flag is currently parsed out of the ERP IE in beacons. This patch allows the ERP IE to be available at assocation time and causes the appropriate actions to be performed earlier. It is slightly complicated by the fact that most APs don't include the ERP IE in association responses. To work around this, we store ERP values in the ieee80211_sta_bss structure. Also added some WLAN_ERP defines for use by upcoming patches. Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2007-07-12[PATCH] mac80211: Implementation of SIOCSIWRATELarry Finger
The WEXT ioctl SIOCSIWRATE is not implemented in mac80211. This patch adds the missing routine. It supports the 'auto' keyword, fixed rates, and the combination of 'auto' and a fixed rate to select an upper bound. Based on the patch from Mohamed Abbas <mabbas@linux.intel.com>.

2007-07-12[PATCH] mac80211: clarify some mac80211 thingsJohannes Berg
The semantics of not having an add_interface callback are not well defined, this callback is required because otherwise you cannot obtain the requested MAC address of the device. Change the documentation to reflect this, add a note about having no MAC address at all, add a warning that mac_addr in struct ieee80211_if_init_conf can be NULL and finally verify that a few callbacks are assigned by way of BUG_ON() Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W.

Interestingly, wpa_supplicant doesn't use it, but uses the currently unsupported IW_AUTH_DROP_UNENCRYPTED. So I guess it doesn't matter anyway. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Jiri Benc <jbenc@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2007-07-12[PATCH] mac80211: kill rate control ioctlsJohannes Berg
These aren't used anywhere (hostapd, wpa_supplicant) and until we have a proper interface to the rate control algorithms they don't make much sense either since e.g. rc80211_lowest won't honour them.

2007-07-10[MAC80211]: Set low initial rate in rc80211_simpleLarry Finger
The initial rate for STA's using rc80211_simple is set to the last rate in the rate table. For situations for which the signal is weak, the rate may be too high for authentication and association. Although the rc80211_simple module will adjust the speed, the response may not be fast enough for a successful connection. This modification sets the initial rate to the lowest supported value.

2007-06-11[PATCH] mac80211: Don't stop tx queue on master device while scanning.Mattias Nissler
mac80211 stops the tx queues during scans. This is wrong with respect to the master deivce tx queue, since stopping it prevents any probes from being sent during the scan. Instead, they accumulate in the queue and are only sent after the scan is finished, which is obviously wrong. Signed-off-by: Mattias Nissler <mattias.nissler@gmx.de> Signed-off-by: John W.

2007-05-29[PATCH] mac80211: fail back to use associate from reassociateZhu Yi
Some APs have strict checking between associate and reassociate. In a case when an AP is restarted during a connection, it denies the mac80211 reassoc request since this is a new association for the AP. To fix this problem, we need to check the status code against WLAN_STATUS_REASSOC_NO_ASSOC and clear ifsta->prev_bssid_set in handling the association failure response.
