From 5061b0c2b9066de426fbc63f1278d2210e789412 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 14 Jul 2009 00:33:34 +0200 Subject: mac80211: cooperate more with network namespaces There are still two places in mac80211 that hardcode the initial net namespace (init_net). One of them is mandated by cfg80211 and will be removed by a separate patch, the other one is used for finding the network device of a pending packet via its ifindex. Remove the latter use by keeping track of the device pointer itself, via the vif pointer, and avoid it going stale by dropping pending frames for a given interface when the interface is removed. To keep track of the vif pointer for the correct interface, change the info->control.vif pointer's internal use to always be the correct vif, and only move it to the vif the driver expects (or NULL for monitor interfaces and injected packets) right before giving the packet to the driver.

"SCAN_SW_SCANNING" tells us that we are currently running a software scan but we might as well be on the operating channel to RX/TX. While "SCAN_SW_SCANNING" is set during the whole scan "SCAN_OFF_CHANNEL" is set when leaving the operating channel and unset when coming back. Introduce two new scan states "SCAN_LEAVE_OPER_CHANNEL" and "SCAN_ENTER_OPER_CHANNEL" which basically implement the functionality we need to leave the operating channel (send a nullfunc to the AP and stop the queues) and enter it again (send a nullfunc to the AP and start the queues again). Enhance the scan state "SCAN_DECISION" to switch back to the operating channel after each scanned channel. In the future it sould be simple to enhance the decision state to scan as much channels in a row as the qos latency allows us. Signed-off-by: Helmut Schaa Signed-off-by: John W.

Rodriguez" Date: Thu, 23 Jul 2009 16:37:47 -0700 Subject: mac80211: fix MLME issuing of probe requests while scanning We were issuing probe requests to the associated AP on the wrong band by having our beacon timer loss trigger while we are scanning. When we would scan the timer could hit and force us to send a probe request to the AP but with a chance we'd be on the wrong band. This leads to finding no usable bitrate but we should not get so far on the xmit path. We should not be trying to send these probe request frames so prevent ieee80211_mgd_probe_ap() from sending these. As it turns out all callers of ieee80211_mgd_probe_ap() need this check so we just move the scan check there. This means we can remove the recenlty added check during ieee80211_sta_monitor_work(). Additionally we now fix a race condition added by the patch "mac80211: do not monitor the connection while scanning" which had the same check in ieee80211_sta_conn_mon_timer(). The race happens because the timer routine *does* a valid check for scanning but after it queues work into the mac80211 workqueue the work callback can kick off with scanning enabled and cause the same issue we were trying to avoid. The more appropriate solution would be to disable the respective timers during scan and re-enable them after scan but requires more complex code and testing.

this patch introduce the Legacy Thermal Management: IWL_TI_0: normal temperature, system power state IWL_TI_1: high temperature detect, low power state IWL_TI_2: higher temperature detected, lower power state IWL_TI_CT_KILL: critical temperature detected, lowest power state Once get into CT_KILL state, uCode go into sleep, driver will stop all the active queues, then move to IWL_TI_CT_KILL state; also set up 5 seconds timer to toggle CSR flag, uCode wake up upon CSR flag change, then measure the temperature. If temperature is above CT_KILL exit threshold, uCode go backto sleep; if temperature is below CT_KILL exit threshold, uCode send Card State Notification response with appropriate CT_KILL status flag, and uCode remain awake, Driver receive Card State Notification Response and update the card temperature to the CT_KILL exit threshold.

this patch introduce the Advance Thermal Throttling: TI-0: system power index, no tx/rx restriction, HT enabled TI-1: power index 5, 1 spatial stream Tx, multiple spatial stream Rx, HT enabled TI-2: power index 5: 1 spatial stream Tx, 1 spatial stream Rx, HT disabled TI-CT-KILL: power index 5, no Tx, no Rx, HT disabled For advance Thermal Throttling, CT_KILL_ENTER threshold and CT_KILL_EXIT threshold are different; uCode will not stay awake until reach CT_KILL_EXIT threshold.

This patch adds the missing deauth handling (telling cfg80211 about it) and also removes the follow-up warnings since they could happen due to races even if nothing is wrong. I've explained the races in the comments. Signed-off-by: Johannes Berg Reported-by: Marcel Holtmann Tested-by: Marcel Holtmann Signed-off-by: John W.

This is what you've all been waiting for! This patch makes cfg80211 take care of wext emulation _completely_ by itself, drivers that don't need things cfg80211 doesn't do yet don't even need to be aware of wireless extensions. This means we can also clean up mac80211's and iwm's Kconfig and make it possible to build them w/o wext now! RIP wext. Signed-off-by: Johannes Berg Signed-off-by: John W.

By default, 40MHz is supported if AP can support the function. By echo "1" to "disable_ht40" file, iwlwifi driver will disable the 40MHz support and only allow 20MHz channel. Because the information exchange happen during association time, so enable/disable ht40 channel only can be performed when it is not associated with AP.
