It is possible that there are different BSS structs with the same BSSID, but we cannot authenticate with multiple of them them because we need the BSSID to be unique for deauthenticating/disassociating. Signed-off-by:

In order to avoid problems with BSS structs going away while they're in use, I've long wanted to make cfg80211 keep track of them. Without the SME, that wasn't doable but now that we have the SME we can do this too. It can keep track of up to four separate authentications and one association, regardless of whether it's controlled by the cfg80211 SME or the userspace SME. Signed-off-by:

This function from mac80211 seems generally useful, and I will need it in cfg80211 soon. Signed-off-by:

When the interface is brought down, we need to reset the auth algorithm because wpa_supplicant doesn't reset it, and then we fail to use shared key auth when required later. Signed-off-by:

When the userspace SME is in control, we are currently not sending events, but this means that any userspace applications using wext or nl80211 to receive events will not know what's going on unless they can also interpret the nl80211 assoc event. Since we have all the required code, let the SME follow events from the userspace SME, this even means that you will be refused to connect() while the userspace SME is in control and connected.

With mac80211 now always controlled by an external SME, a lot of code is dead -- SSID, BSSID, channel selection is always done externally, etc. Additionally, rename IEEE80211_STA_TKIP_WEP_USED to IEEE80211_STA_DISABLE_11N and clean up the code a bit. Signed-off-by:

The automatic auth algorithm issue is now solved in cfg80211, so mac80211 no longer needs code to try different algorithms -- just using whatever cfg80211 asked for is good. Signed-off-by:

The IEEE80211_STA_TKIP_WEP_USED flag is used internally to disable HT when WEP or TKIP are used. Now that cfg80211 is giving us the required information, we can set the flag appropriately again. Signed-off-by:

By dropping the noise reporting, we can implement wireless stats in cfg80211. We also make the handler return NULL if we have no information, which is possible thanks to the recent wext change. Signed-off-by:

For now, let's implement that using a very hackish way: simply mirror the wext API in the cfg80211 API. This will have to be changed later when we implement proper bitrate API. Signed-off-by:

Just on/off and timeout, and with a hacky cfg80211 method until we figure out what we want, though this is probably sufficient as we want to use pm_qos for wifi everywhere. Signed-off-by:

This adds code to make it possible to use the cfg80211 connect() API with wireless extensions, and because the previous patch added emulation of that API with auth() and assoc(), by extension also supports wext on that. At the same time, removes code from mac80211 for wext, but doesn't yet clean up mac80211's mlme code more. Signed-off-by:

This adds code to cfg80211 so that drivers (mac80211 right now) that don't implement connect but rather auth/assoc can still be used with the nl80211 connect command. This will also be necessary for the wext compat code. Signed-off-by:

This patch introduces the cfg80211 connect/disconnect API. The goal here is to run the AUTH and ASSOC steps in one call. This is needed for some fullmac cards that run both steps directly from the target, after the host driver sends a connect command. Additionally, all the new crypto parameters for connect() are now also valid for associate() -- although associate requires the IEs to be used, the information can be useful for drivers and should be given.

We'll need these values for some drivers using connect API and for wext compat code, so let's define them. Signed-off-by:

The ieee80211_scan_results function hasn't existed for a long time now, so its declaration should be removed as well. Signed-off-by:

This introduces a new NL80211_CMD_TESTMODE for testing and calibration use with nl80211. There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

When the auth algorithm is rejected, but we don't have another one to try, we will eventually retry but that isn't useful -- we'll then do it again and again until we eventually give up. Instead, we should let the SME know and go into disabled state. The same applies for situations where the AP rejects with any other status code. Additionally, when trying the next auth algorithm, we should reset the auth_tries so that just a single lost frame doesn't lead to us giving up on the third auth algorithm. Signed-off-by:

This variable isn't necessary -- the wext code keeps track of the BSSID itself, and otherwise we have current_bss. Signed-off-by:

Instead of hardcoding GFP_ATOMIC everywhere, add a new function parameter that gets the flags from the caller. Obviously then I need to update all callers (all of them in mac80211), and it turns out that now it's ok to use GFP_KERNEL in almost all places. Signed-off-by:

Move a break statement to the correct place _after_ the #endif, otherwise w/o WIRELESS_EXT things break badly. Also, while touching this code, do a cleanup and assign dev->ieee80211_ptr to a new variable. Signed-off-by:

The way I initially thought we could do wireless extensions is by making all the compat code in cfg80211 be independent of CONFIG_WIRELESS_EXT, but this is turning out to not be feasible. Therefore, fix the Kconfig help text and make the option default to yes, so people won't get a nasty surprise when mac80211 will get rid of its 'select WIRELESS_EXT' any time now. Signed-off-by:

The key todo lock can be taken from different locks that require it to be _bh to avoid lock inversion due to (soft)irqs. This should fix the two problems reported by Bob and Gabor: http://mid.gmane.org/20090619113049.GB18956@hash.localnet http://mid.gmane.org/4A3FA376.8020307@openwrt.orgSigned-off-by:

Currently, wext drivers cannot return NULL for stats even though that would make the ioctl return -EOPNOTSUPP because that would mean they are no longer listed in /proc/net/wireless. This patch changes the wext core's behaviour to list them if they have any wireless_handlers, but only show their stats when available, so that drivers can start returning NULL if stats are currently not available, reducing confusion for e.g. IBSS.

This removes the custom scan cache used by orinoco. We also have to avoid calling cfg80211_scan_done from the hard interrupt, so we offload the entirety of scan processing to a workqueue. This may behave strangely if you start scanning just prior to suspending... Signed-off-by:

With the move to cfg80211 it's nice to keep the hardware operations distinct from the interface, even though we can only support a single interface. This also means the driver resembles other cfg80211 drivers. Signed-off-by:
