2008-01-28mac80211: add unified BSS configurationJohannes Berg
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.

2008-01-28mac80211: add beacon configuration via cfg80211Johannes Berg
This patch implements the cfg80211 hooks for configuring beaconing on an access point interface in mac80211. While doing so, it fixes a number of races that could badly crash the machine when the beacon is changed while being requested by the driver.

2008-01-28mac80211: move interface type to vif structureJohannes Berg
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.

2008-01-28mac80211: clean up eapol frame handling/port controlJohannes Berg
This cleans up the eapol frame handling and some related code in the receive and transmit paths. After this patch * EAPOL frames addressed to us or the EAPOL group address are always accepted regardless of whether they are encrypted or not * other frames from a station are dropped if PAE is enabled and the station is not authorized * unencrypted frames (except the EAPOL frames above) are dropped if drop_unencrypted is enabled * some superfluous code that eth_type_trans handles anyway is gone * port control is done for transmitted packets Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2007-10-10[PATCH] mac80211: validate VLAN interfaces betterJohannes Berg
This patch changes mac80211 to verify that VLAN interfaces are valid and not bother drivers about them any more. VLAN interfaces are now only valid when an AP interface is up with the same MAC address, and are automatically turned off when the AP interface is set down.

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.

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.
