The "what-was-I-thinking-if-anything" patch. Clearly, if cfg80211_send_disassoc() does wdev_lock() and then calls __cfg80211_send_disassoc(), the latter shouldn't lock again. And the sme_state test is ... no further comments. Signed-off-by:

Implement set_tim callback for all rt2x00 drivers, this makes the device wake up powersaving stations properly while in AP mode. The only way to update the beacon is by simply calling mac80211 and requesting the new beacon. This means the set_tim() event is mostly the same as a beacon_done() event which was already defined in rt2x00lib. Signed-off-by:

When connected to a BSS, or joined to an IBSS, we'll want to know in userspace without using wireless extensions, so report the BSS status in the BSS list. Userspace can query the BSS list, display all the information and retrieve the station information as well. For example (from hwsim): $ iw dev wlan1 scan dump BSS 02:00:00:00:00:00 (on wlan1) -- associated freq: 2462 beacon interval: 100 capability: ESS ShortSlotTime (0x0401) signal: -50.00 dBm SSID: j Supported rates: 1.0* 2.0* 5.5* 11.0* 6.0 9.0 12.0 18.0 DS Paramater set: channel 11 ERP: <no flags> Extended supported rates: 24.0 36.0 48.0 54.0 Signed-off-by:

Pavel reported that you can't set the SSID from "foo" to "bar". I tried reproducing, but used different values, with different lengths, and thus never saw the obvious problem. Reported-by:

This variable is only used internally, _while_ connected. If we use it, the sequence # iwconfig wlan1 essid foo <connects> # iwconfig wlan1 essid "" <disconnects> # iwconfig will still display "foo" as the SSID afterwards, which is obviously quite bogus. Fix this by only displaying the wext SSID, if present. Signed-off-by:

There's no reason to think that hwsim has any actual signal strength, but for testing it is very useful to have it report _some_ value to the stack so I can see if the value ends up being reported correctly Signed-off-by:

Johannes Berg authored
Instead of using the wext BSSID which may be NULL if you haven't explicitly set one, we should instead use the current_bss pointer -- if that's NULL we aren't connected anyway. Fixes missing signal quality output reported to me internally at Intel. Signed-off-by:

1) there's a spin_lock() that needs to be spin_lock_bh() 2) action frames of size 24 might cause an out-of-bounds memory access (for the 25th byte only, so no big deal) Signed-off-by:

The cfg80211_sme_disassoc() function is already holding a lock here that cfg80211_mlme_deauth() would take, so it needs to use __cfg80211_mlme_deauth() instead. Signed-off-by:

Johannes Berg authored
With the recent MLME rework I accidentally removed the connection monitoring code. In order to add it back, this patch will add new code to monitor both for beacon loss and for the connection actually working, with possibly separate triggers. When no unicast frames have been received from the AP for (currently) two seconds, we will send the AP a probe request. Also, when we don't see beacons from the AP for two seconds, we do the same (but those times need not be the same due to the way the code is now written). Additionally, clean up the parameters to the ieee80211_set_disassoc() function that I need here, those are all useless except sdata. Signed-off-by:

We have, sometimes, multiple things that want to run but don't have their own timer. Introduce a new function to mac80211's mlme run_again() that makes sure that the timer will run again at the _first_ needed time, use that function and also properly reprogram the timer once it fired.

We need to provide a reasonable minimum that will result in a working setup if used. Set minimum to be 10 to provide for 4 standard TX queues + 1 command queue + 2 (unused) HCCA queues + 4 HT queues (one per AC). We allow the user to change the number of queues used via a module parameter and use this minimum value to check if it is valid. Without this patch a user can select a value for the number of queues that will result in a failing setup. Signed-off-by:

* Rename maximum number of queue (TFD_QUEUE_MAX) to IWL39_NUM_QUEUES to be consistent with rest of iwlwifi. * Remove unused defines. * Fix loops that iterate over number of TX queues to stop when maximum is reached (currently it is maximum + 1). * Remove queues_num module parameter as it is not used.

debugfs files are created with 644 permissions which gives everybody read access. This presents a security issue if a user opens the file and holds it open at the time the driver removes the file. At this point invalid memory will be accessed. Fix this by only allowing root to read debugfs files. Signed-off-by:

This reworks the key operation in cfg80211, and now only allows, from userspace, configuring keys (via nl80211) after the connection has been established (in managed mode), the IBSS been joined (in IBSS mode), at any time (in AP[_VLAN] modes) or never for all the other modes. In order to do shared key authentication correctly, it is now possible to give a WEP key to the AUTH command. To configure static WEP keys, these are given to the CONNECT or IBSS_JOIN command directly, for a userspace SME it is assumed it will configure it properly after the connection has been established. Since mac80211 used to check the default key in IBSS mode to see whether or not the network is protected, it needs an update in that area, as well as an update to make use of the WEP key passed to auth() for shared key authentication.

We will soon want to nest key attributes into some new attribute for configuring static WEP keys at connect() and ibss_join() time, so we need nested attributes for that. However, key attributes right now are 'global'. This patch thus introduces new nested attributes for the key settings and functions for parsing them. Signed-off-by:

This fixes two small bugs: 1) the connect variable is already initialised, and the assignment to auth_type overwrites the previous setting with a wrong value 2) when all authentication attempts fail, we need to report that we couldn't connect Signed-off-by: -

cfg80211_wext_giwrate doesn't lock the wdev, so it cannot access current_bss race-free. Also, there's little point in trying to ask the driver for an AP that it never told us about, so avoid that case. Signed-off-by:

A pointer to mac_sonic_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. Various other functions that are called by mac_sonic_probe need to move to .devinit.text, too. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver. Signed-off-by:
