2012-06-13mac80211: stop polling in disassociationDavid Spinadel1-2/+2
Stop connection monitor poll during disassociation. This clears the polling flags and if a scan was deferred it will be run. Without this fix, if a scan was deferred due to connection monitoring while disassociation happens, this scan blocks further scan requests until interface down/up which causes problems connecting to another AP.

2012-06-13cfg80211: fix potential deadlock in regulatoryEliad Peller1-1/+1
reg_timeout_work() calls restore_regulatory_settings() which takes cfg80211_mutex. reg_set_request_processed() already holds cfg80211_mutex before calling cancel_delayed_work_sync(reg_timeout), so it might deadlock.

2012-06-08Bluetooth: Fix deadlock and crash when SMP pairing times outJohan Hedberg1-1/+6
The l2cap_conn_del function tries to cancel_sync the security timer, but when it's called from the timeout function itself a deadlock occurs. Subsequently the "hcon->l2cap_data = NULL" that's supposed to protect multiple calls to l2cap_conn_del never gets cleared and when the connection finally drops we double free's etc which will crash the kernel. This patch fixes the issue by using the HCI_CONN_LE_SMP_PEND for protecting against this. The same flag is also used for the same purpose in other places in the SMP code.

2012-06-06mac80211: unify SW/offload remain-on-channelJohannes Berg9-751/+532
Redesign all the off-channel code, getting rid of the generic off-channel work concept, replacing it with a simple remain-on-channel list. This fixes a number of small issues with the ROC implementation: * offloaded remain-on-channel couldn't be queued, now we can queue it as well, if needed * in iwlwifi (the only user) offloaded ROC is mutually exclusive with scanning, use the new queue to handle that case -- I expect that it will later depend on a HW flag The bigger issue though is that there's a bad bug in the current implementation: if we get a mgmt TX request while HW roc is active, and this new request has a wait time, we actually schedule a software ROC instead since we can't guarantee the existing offloaded ROC will still be that long. To fix this, the queuing mechanism was needed. The queuing mechanism for offloaded ROC isn't yet optimal, ideally we should add API to have the HW extend the ROC if needed. We could add that later but for now use a software implementation. Overall, this unifies the behaviour between the offloaded and software-implemented case as much as possible.

2012-06-06mac80211: do remain-on-channel while idleJohannes Berg4-24/+10
The IDLE handling in HW off-channel is broken right now since we turn off IDLE only when the off-channel period already started. Therefore, all drivers that use it today (only iwlwifi!) must support off-channel while idle, so playing with idle isn't needed at all. Off-channel in general, since it's no longer used for authentication/association, shouldn't affect PS, so also remove that logic. Also document a small caveat for reporting TX status from off-channel frames in HW remain-on-channel. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

Just like the AP mode patch, instead of setting the channel and then joining the mesh network, provide the channel to join the network on to the join_mesh() function. Like in AP mode, you can also give the channel to the join-mesh nl80211 command now. Unlike AP mode, it picks a default channel if none was given. As libertas uses mesh mode interfaces but has no join_mesh callback and we can't simply break it, keep some compatibility code for that case and configure the channel directly for it. In the non-libertas case, where we store the channel until join, allow setting it while the interface is down. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-06-05cfg80211: provide channel to start_ap functionJohannes Berg2-2/+56
Instead of setting the channel first and then starting the AP, let cfg80211 store the channel and provide it as one of the AP settings. This means that now you have to set the channel before you can start an AP interface, but since hostapd/wpa_supplicant always do that we're OK with this change. Alternatively, it's now possible to give the channel as an attribute to the start-ap nl80211 command, overriding any preset channel.

2012-06-05cfg80211: simplify cfg80211_can_beacon_sec_chan APIJohannes Berg2-18/+7
Change cfg80211_can_beacon_sec_chan() to return true if there is no secondary channel to simplify all the current users of it. They all check the channel type before calling the function because it returns false if there's no secondary channel. Also actually document the return value.

2012-06-05mac80211: clean up ieee80211_set_channelJohannes Berg1-16/+2
There's no need for ieee80211_set_channel to check whether a change in configuration happened since ieee80211_hw_config() auto-detects it. Additionally, it's wrong to pretend the HT config for the BSS changed, it didn't, the BSS can't be up & running (AP beaconing etc.) when the channel type is changed anyway.

2012-06-05cfg80211: deprecate CFG80211_WEXTJohannes Berg1-1/+0
Almost all wireless tools have transitioned to or at least added compatibility with nl80211 so there's no real need for CONFIG_CFG80211_WEXT any more.

ieee80211_get_operstate() was used by drivers in order to know whether the sta link is up, but it's no longer needed (nor used) as mac80211 notifies the drivers about authorization changes (via the sta_state callback) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: John W.

2012-06-05mac80211: fail authentication when AP denied authenticationEliad Peller1-2/+2
ieee80211_rx_mgmt_auth() doesn't handle denied authentication properly - it authenticates the station and waits for association (for 5 seconds) instead of failing the authentication. Fix it by destroying auth_data and bailing out instead.

2012-06-05mac80211: use offchannel queue only when supportedEliad Peller1-3/+5
Commit 3a25a8c ("mac80211: add improved HW queue control") added support for offchannel queue mapping. However, this mapping is only valid when the driver supports IEEE80211_HW_QUEUE_CONTROL. Check whether the driver supports IEEE80211_HW_QUEUE_CONTROL before setting the hw_queue to the mapped offchannel queue. (This patch doesn't have any actual effect, because hw_queue is overridden in ieee80211_tx() anyway, so this is merely some cleanup) Signed-off-by: Eliad Peller <eliad@wizery.com> Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
