2008-11-18mac80211: remove ieee80211_notify_macJohannes Berg
Before ieee80211_notify_mac() was added, it was presented with the use case of using it to tell mac80211 that the association may have been lost because the firmware crashed/reset. Since then, it has also been used by iwlwifi to (slightly) speed up re-association after resume, a workaround around the fact that mac80211 has no suspend/resume handling yet. It is also not used by any other drivers, so clearly it cannot be necessary for "good enough" suspend/resume. Unfortunately, the callback suffers from a severe problem: It only works for station mode. If suspend/resume happens while in IBSS or any other mode (but station), then the callback is pointless. Recently, it has created a number of locking issues, first because it required rtnl locking rather than RCU due to calling sleeping functions within the critical section, and now because it's called by iwlwifi from the mac80211 workqueue that may not use the rtnl because it is flushed under rtnl. (cf. http://bugzilla.kernel.org/show_bug.cgi?id=12046) I think, therefore, that we should take a step back, remove it entirely for now and add the small feature it provided properly. For suspend and resume we will need to introduce new hooks, and for the case where the firmware was reset the driver will probably simply just pretend it has done a suspend/resume cycle to get mac80211 to reprogram the hardware completely, not just try to connect to the current AP again in station mode. When doing so, we will need to take into account locking issues and possibly defer to schedule_work from within mac80211 for the resume operation, while the suspend operation must be done directly. Proper suspend/resume should also not necessarily try to reconnect to the current AP, the time spent in suspend may have been short enough to not be disconnected from the AP, mac80211 will detect that the AP went out of range quickly if it did, and if the association is lost then the AP will disassoc as soon as a data frame is sent. We might also take into account WWOL then, and have mac80211 program the hardware into such a mode where it is available and requested.

2008-11-12mac80211: fix notify_mac functionJohannes Berg
The ieee80211_notify_mac() function uses ieee80211_sta_req_auth() which in turn calls ieee80211_set_disassoc() which calls a few functions that need to be able to sleep, so ieee80211_notify_mac() cannot use RCU locking for the interface list and must use rtnl locking instead.

2008-11-10mac80211: Allow AP mode to be enabledJouni Malinen
With the addition of basic rate set and TX queue parameter configuration and confirmation that power save buffering is working again, mac80211 is now in state that allows AP mode to be used without major problems. Consequently, it is time to allow this mode to be enabled without having to patch the kernel. AP mode requires hostapd for management frame processing and as such, configuring this mode is only allowed through cfg80211 (not with iwconfig and WEXT).

2008-11-10mac80211: remove SSID driver codeJohannes Berg
Remove the SSID from the driver API since now there is no driver that requires knowing the SSID and I think it's unlikely that any hardware design that does require the SSID will play well with mac80211.

2008-10-31mac80211: insert AP sta entry after filling itJohannes Berg
We never clearly defined the semantics of the sta_notify callback and it was originally posted for iwlwifi which still doesn't use it at all.

Moved struct mesh_config from mac80211/ieee80211_i.h to net/cfg80211.h. nl80211_get_mesh_params and nl80211_set_mesh_params unpack the netlink messages and ask the driver to get or set the configuration.

2008-10-31mac80211: inform userspace of probe/auth/assoc timeoutJohannes Berg
I noticed that when for some reason [1] the probe or auth times out, wpa_supplicant doesn't realise this and only tries the next AP when it runs into its own timeout, which is ten seconds, and that's quite long. Fix this by making mac80211 notify userspace that it didn't associate. [1] my wrt350n in mixed B/G/HT mode often runs into this, maybe it's because one of the antennas is broken off and for whatever reason it decides to use that antenna to transmit the response frames (auth, probe); I do see beacons fine so it's not totally broken. Works fine in pure-G mode. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-10-31mac80211: remove rate_control_clearJohannes Berg

2008-10-31mac80211: rewrite HT handlingJohannes Berg
The HT handling has the following deficiencies, which I've (partially) fixed: * it always uses the AP info even if there is no AP, hence has no chance of working as an AP * it pretends to be HW config, but really is per-BSS * channel sanity checking is left to the drivers * it generally lets the driver control too much HT enabling is still wrong with this patch if you have more than one virtual STA mode interface, but that never happens currently. Once WDS, IBSS or AP/VLAN gets HT capabilities, it will also be wrong, see the comment in ieee80211_enable_ht(). Additionally, this fixes a number of bugs: * mac80211: ieee80211_set_disassoc doesn't notify the driver any more since the refactoring * iwl-agn-rs: always uses the HT capabilities from the wrong stuff mac80211 gives it rather than the actual peer STA * ath9k: a number of bugs resulting from the broken HT API I'm not entirely happy with putting the HT capabilities into struct ieee80211_sta as restricted to our own HT TX capabilities, but I see no cleaner solution for now.

2008-10-31mac80211: provide sequence numbersJohannes Berg
I've come to think that not providing sequence numbers for the normal STA mode case was a mistake, at least two drivers now had to implement code they wouldn't otherwise need, and I believe at76_usb and adm8211 might be broken. This patch makes mac80211 assign a sequence number to all those frames that need one except beacons. That means that if a driver only implements modes that do not do beaconing it need not worry about the sequence number. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
