* mac80211: start moving scan code from mlmeJohannes Berg2008-09-11
| | | | | | | | | Here's a first patch to move some code from mlme.c to a new file called scan.c. The end result will hopefully be a more manageable mlme.c. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: remove useless non-NULL tests from scan results codeJohannes Berg2008-09-11
| | | | | | | I'm surprised nobody complained about these before. What a waste. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: use sdata pointer for scan interfaceJohannes Berg2008-09-11
| | | | | | | | | Since we now use sdata pointers most of the time, using a netdev pointer here is somewhat artificial, use an sdata pointer instead. Replace a netdev-prefix in a few messages by a wiphy-prefix. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: reorder mlme codeJohannes Berg2008-09-11
| | | | | | | | | This reorders the mlme code a bit so we don't need all the forward function declarations. It also removes the ERP_INFO_USE_PROTECTION define that is unused, but otherwise contains no real changes. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: stop queues before carrier offTomas Winkler2008-09-11
| | | | | | | | | | | | | During testing of the disassociation fixes, Tomas noticed that it was possible to run into a situation where you'd suddenly get a few "wlan0: dropped frame to <AP> (unauthorized port)" messages and I found this to be due to the AP's sta_info having been removed but netif_carrier_off not having removed/stopped traffic yet. To avoid that, stop the queue for the interface (and avoid bringing them up when another vif scans when they weren't up.)

* mac80211: remove disassociation code from ieee80211_set_associatedTomas Winkler2008-09-11
| | | | | | | | | | | | This patch moves disassociation code from ieee80211_set_associated to ieee80211_set_disassoc. To reduce code duplication, it introduces the ieee80211_sta_send_apinfo function. Additionally, it fixes a lapse where BSS_CHANGED_HT wasn't set when notifying the driver of changes due to disassociation.

* mac80211: disassociate when moving to new BSSTomas Winkler2008-09-11
| | | | | | | | | | | | | This patch makes the MLME cleanly disassociate from the current BSS when leaving it for a new one. This is not just nicer to the old AP (we're leaving it, might as well tell it!) but also required for some drivers that keep track of the station we're associated with, they'd get confused because they'd think we are associated with two APs.

* mac80211: restructure disassoc/deauth flowsTomas Winkler2008-09-11
| | | | | | | | | | | | | | This patch restructure the flow of disassociation and deauthentication flows to be consistent under all circumstances. It ensures that BA session is treated down before deauthentication or disassociation, adds the removal of the obsolete sta form station table and fixes a related bug (sta_info_destroy without sta_info_unlink) in ieee80211_associated() and reduce some code duplication Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: Tomas Winkler <tomas.winkler@intel.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* mac80211: move IE parsing to util fileJohannes Berg2008-09-11
| | | | | | | | | Since IE parsing is required for the mlme and mesh code, it's not a static function anyway, and it's much better to have it in util rather than the overly large mlme.c Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: fix typo in action frame handlingJohannes Berg2008-09-11
| | | | | | | | | | This says chan_switch.action_code but really means measurement.action_code, of course the actual offset in the frame is the same, it's just harder to understand this way.

* mac80211: fix action frame length checksJohannes Berg2008-09-11
| | | | | | | | | | The action frame length checks are one too small, there's not just an action code as the comment makes you believe, there's a category code too, and the category code is required in each action frame (hence part of IEEE80211_MIN_ACTION_SIZE).

* mac80211: BSS info: check channel firstJohannes Berg2008-09-11
| | | | | | | | | | | When we receive information about a BSS we check at some point whether or not we think we're allowed to use the channel it is on, but we do that fairly late. I don't think we should do it that late, so do it earlier to avoid doing IBSS/mesh stuff on that channel and then getting confused because it's disabled.

* mac80211: make conf_tx non-atomicJohannes Berg2008-09-11
| | | | | | | | | | | The conf_tx callback currently needs to be atomic, this requirement is just because it can be called from scanning. This rearranges it slightly to only update while not scanning (which is fine, we'll be getting beacons when associated) and thus removes the atomic requirement.

* mac80211: move some RCU locking into an if branchJohannes Berg2008-09-11

* ipv6: On interface down/unregister, purge icmp routes too.David S. Miller2008-09-11
| | | | | | | | | | | | | | | | | Johannes Berg reported that occaisionally, bringing an interface down or unregistering it would hang for up to 30 seconds. Using debugging output he provided it became clear that ICMP6 routes were the culprit. The problem is that ICMP6 routes live in their own world totally separate from normal ipv6 routes. So there are all kinds of special cases throughout the ipv6 code to handle this. While we should really try to unify all of this stuff somehow, for the time being let's fix this by purging the ICMP6 routes that match the device in question during rt6_ifdown().

* ipsec: Use RCU-like construct for saved state within a walkHerbert Xu2008-09-09
| | | | | | | | | | | | | | | | | Now that we save states within a walk we need synchronisation so that the list the saved state is on doesn't disappear from under us. As it stands this is done by keeping the state on the list which is bad because it gets in the way of the management of the state life-cycle. An alternative is to make our own pseudo-RCU system where we use counters to indicate which state can't be freed immediately as it may be referenced by an ongoing walk when that resumes.
