2012-03-06mac80211: use compare_ether_addr on MAC addresses instead of memcmpFelix Fietkau1-5/+5

2012-01-31mac80211: station state transition error handlingJohannes Berg1-3/+3
In the future, when we start notifying drivers, state transitions could potentially fail. To make it easier to distinguish between programming bugs and driver failures: * rename sta_info_move_state() to sta_info_pre_move_state() which can only be called before the station is inserted (and check this with a new station flag). * rename sta_info_move_state_checked() to just plain sta_info_move_state(), as it will be the regular function that can fail for more than just one reason (bad transition or an error from the driver) This makes the programming model easier -- one of the functions can only be called before insertion and can't fail, the other can fail.

2012-01-27mac80211: Do not scan for IBSS merge with a fixed BSSID.Nicolas Cavallari1-2/+3
Currently, when we are on an IBSS network with no active station, we would scan for other BSSID, even if fixed_bssid is on, due to a bug in ibss.c, where fixed_channel would be checked instead of fixed_bssid. This would trigger useless scans where scan results would not be used anyway. This patch also reverts commit 39d02a7d90602d4557ee05db2a157a4e0, which assumed that the ifibss->fixed_channel check was legitimate to disable single-channel scans. IBSS single-channel scan should now be fixed. Signed-off-by: Nicolas Cavallari <cavallar@lri.fr> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2012-01-24mac80211: in IBSS use the Auth frame to trigger STA reinsertionAntonio Quartulli1-36/+49
In case of a node re-joining the cell the sta_info structure belonging to it is first destroyed and then reinserted. In this way its internal state is reset. The joining operation is recognised thank the Auth frame being received. This operation is helpful in case of a node being rebooted that is joining the ad-hoc cell again, before its purge timeout on other nodes expires.

2011-12-15mac80211: delay IBSS station insertionJohannes Berg1-32/+122
In order to notify drivers and simplify the station management code, defer IBSS station insertion to a work item and don't do it directly while receiving a frame. This increases the complexity in IBSS a little bit, but it's pretty straight forward and it allows us to reduce the station management complexity (next patch) considerably.

2011-12-15mac80211: refactor station state transitionsJohannes Berg1-1/+4
Station entries can have various states, the most important ones being auth, assoc and authorized. This patch prepares us for telling the driver about these states, we don't want to confuse drivers with strange transitions, so with this we enforce that they move in the right order between them (back and forth); some transitions might happen before the driver even knows about the station, but at least runtime transitions will be ordered correctly. As a consequence, IBSS and MESH stations will now have the ASSOC flag set (so they can transition to AUTHORIZED), and we can get rid of a special case in TX processing. When freeing a station, unwind the state so that other parts of the code (or drivers later) can rely on the transitions. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2011-12-07mac80211: Add HT operation modes for IBSSAlexander Simon1-9/+74
The HT mode is set by iw (previous patchsets). The interface is set into the specified HT mode. HT mode and capabilities are announced in beacons. If we add a station that uses HT also, the fastest matching HT mode will be used for transmission. That means if we are using HT40+ and we add a station running on HT40-, we would transfer at HT20. If we join an IBSS with HT40, but the secondary channel is not available, we will fall back into HT20 as well. Allow frame aggregation to start in IBSS mode.

2011-06-08mac80211: fix IBSS teardown raceJohannes Berg1-2/+4
Ignacy reports that sometimes after leaving an IBSS joining a new one didn't work because there still were stations on the list. He fixed it by flushing stations when attempting to join a new IBSS, but this shouldn't be happening in the first case. When I looked into it I saw a race condition in teardown that could cause stations to be added after flush, and thus cause this situation. Ignacy confirms that after applying my patch he hasn't seen this happen again.

This adds sparse RCU annotations to most of mac80211, only the mesh code remains to be done. Due the the previous patches, the annotations are pretty simple. The only thing that this actually changes is removing the RCU usage of key->sta in debugfs since this pointer isn't actually an RCU-managed pointer (it only has a single assignment done before the key even goes live).

Extend channel to frequency mapping for 802.11j Japan 4.9GHz band, according to IEEE802.11 section 17.3.8.3.2 and Annex J. Because there are now overlapping channel numbers in the 2GHz and 5GHz band we can't map from channel to frequency without knowing the band. This is no problem as in most contexts we know the band. In places where we don't know the band (and WEXT compatibility) we assume the 2GHz band for channels below 14. This patch does not implement all channel to frequency mappings defined in 802.11, it's just an extension for 802.11j 20MHz channels. 5MHz and 10MHz channels as well as 802.11y channels have been omitted. The following drivers have been updated to reflect the API changes: iwl-3945, iwl-agn, iwmc3200wifi, libertas, mwl8k, rt2x00, wl1251, wl12xx. The drivers have been compile-tested only.

2010-07-21mac80211: fix IBSS lockdep complaintJohannes Berg1-5/+14
Bob reported a lockdep complaint originating in the mac80211 IBSS code due to the common work struct patch. The reason is that the IBSS and station mode code have different locking orders for the cfg80211 wdev lock and the work struct (where "locking" implies running/canceling). Fix this by simply not canceling the work in the IBSS code, it is not necessary since when the REQ_RUN bit is cleared, the work will run without effect if it runs. When the interface is set down, it is flushed anyway, so there's no concern about it running after memory has been invalidated either. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=16419 Additionally, looking into this I noticed that there's a small window while the IBSS is torn down in which the work may be rescheduled and the REQ_RUN bit be set again after leave() has cleared it when a scan finishes at exactly the same time. Avoid that by setting the ssid_len to zero before clearing REQ_RUN which signals to the scan finish code that this interface is not active.
