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: conserve stack space due to paddingJohannes Berg
This patch reorders some fields in struct ieee802_11_elems to save 17*7 or 17*3 bytes (on 64/32-bit machines respectively) stack space in a few functions.

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.
