mac80211: shorten the IBSS debug messages

2018-10-13T07:09:29Z

[ Upstream commit c6e57b3896fc76299913b8cfd82d853bee8a2c84 ] When tracing is enabled, all the debug messages are recorded and must not exceed MAX_MSG_LEN (100) columns. Longer debug messages grant the user with: WARNING: CPU: 3 PID: 32642 at /tmp/wifi-core-20180806094828/src/iwlwifi-stack-dev/net/mac80211/./trace_msg.h:32 trace_event_raw_event_mac80211_msg_event+0xab/0xc0 [mac80211] Workqueue: phy1 ieee80211_iface_work [mac80211] RIP: 0010:trace_event_raw_event_mac80211_msg_event+0xab/0xc0 [mac80211] Call Trace: __sdata_dbg+0xbd/0x120 [mac80211] ieee80211_ibss_rx_queued_mgmt+0x15f/0x510 [mac80211] ieee80211_iface_work+0x21d/0x320 [mac80211] Signed-off-by: Emmanuel Grumbach Signed-off-by: Luca Coelho Signed-off-by: Johannes Berg Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

mac80211: Requeue work after scan complete for all VIF types.

2016-02-15T20:42:34Z

[ Upstream commit 4fa11ec726a32ea6dd768dbb2e2af3453a98ec0a ] During a sw scan ieee80211_iface_work ignores work items for all vifs. However after the scan complete work is requeued only for STA, ADHOC and MESH iftypes. This occasionally results in event processing getting delayed/not processed for iftype AP when it coexists with a STA. This can result in data halt and eventually disconnection on the AP interface.

mac80211: use secondary channel offset IE also beacons during CSA

2014-10-29T15:37:45Z

If we are switching from an HT40+ to an HT40- channel (or vice-versa), we need the secondary channel offset IE to specify what is the post-CSA offset to be used. This applies both to beacons and to probe responses. In ieee80211_parse_ch_switch_ie() we were ignoring this IE from beacons and using the *current* HT information IE instead. This was causing us to use the same offset as before the switch. Fix that by using the secondary channel offset IE also for beacons and don't ever use the pre-switch offset. Additionally, remove the "beacon" argument from ieee80211_parse_ch_switch_ie(), since it's not needed anymore.

mac80211: add Intel Mobile Communications copyright

2014-09-05T11:52:06Z

Our legal structure changed at some point (see wikipedia), but we forgot to immediately switch over to the new copyright notice. For files that we have modified in the time since the change, add the proper copyright notice now. Signed-off-by: Johannes Berg Signed-off-by: Emmanuel Grumbach Signed-off-by: Johannes Berg

mac80211: don't duplicate station QoS capability data

2014-08-15T12:38:08Z

We currently track the QoS capability twice: for all peer stations in the WLAN_STA_WME flag, and for any clients associated to an AP interface separately for drivers in the sta->sta.wme field. Remove the WLAN_STA_WME flag and track the capability only in the driver-visible field, getting rid of the limitation that the field is only valid in AP mode.

mac80211: add QoS IE during TDLS setup start

2014-07-21T10:14:04Z

If QoS is supported by the card, add an appropriate IE to TDLS setup- request and setup-response frames. Consolidate the setting of the WMM info IE across mac80211. Signed-off-by: Arik Nemtsov Reviewed-by: Liad Kaufman Reviewed-by: Johannes Berg Signed-off-by: Johannes Berg

mac80211: move csa counters from sdata to beacon/presp

2014-06-23T12:22:06Z

Having csa counters part of beacon and probe_resp structures makes it easier to get rid of possible races between setting a beacon and updating counters on SMP systems by guaranteeing counters are always consistent against given beacon struct. While at it relax WARN_ON into WARN_ON_ONCE to prevent spamming logs and racing. Signed-off-by: Michal Kazior [remove pointless array check] Signed-off-by: Johannes Berg

mac80211: fix IBSS join by initializing last_scan_completed

2014-05-27T06:54:01Z

Without this fix, freshly rebooted Linux creates a new IBSS instead of joining an existing one. Only when jiffies counter overflows after 5 minutes the IBSS can be successfully joined.

mac80211: Support multiple CSA counters
