This function from mac80211 seems generally useful, and I will need it in cfg80211 soon. 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.

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.

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:

To be easier on drivers and users, have cfg80211 register an rfkill structure that drivers can access. When soft-killed, simply take down all interfaces; when hard-killed the driver needs to notify us and we will take down the interfaces after the fact. While rfkilled, interfaces cannot be set UP.

This patch introduces new cfg80211 API to set the TX power via cfg80211, puts the wext code into cfg80211 and updates mac80211 to use all that. The -ENETDOWN bits are a hack but will go away soon. Signed-off-by:

The patch moves some utility functions from mac80211 to cfg80211. Because these functions are doing generic 802.11 operations so they are not mac80211 specific. The moving allows some fullmac drivers to be also benefit from these utility functions. Signed-off-by:

Some applications using wireless extensions expect to be able to remove a key that doesn't exist. One example is wpa_supplicant which doesn't actually change behaviour when running into an error while trying to do that, but it prints an error message which users interpret as wpa_supplicant having problems. The safe thing to do is not change the behaviour of wireless extensions any more, so when the driver reports -ENOENT let the wext bridge code return success to userspace. To guarantee this, also document that drivers should return -ENOENT when the key doesn't exist. Signed-off-by:

We are not correctly listening to the regulatory max bandwidth settings. To actually make use of it we need to redesign things a bit. This patch does the work for that. We do this to so we can obey to regulatory rules accordingly for use of HT40. We end up dealing with HT40 by having two passes for each channel. The first check will see if a 20 MHz channel fits into the channel's center freq on a given frequency range. We check for a 20 MHz banwidth channel as that is the maximum an individual channel will use, at least for now. The first pass will go ahead and check if the regulatory rule for that given center of frequency allows 40 MHz bandwidths and we use this to determine whether or not the channel supports HT40 or not. So to support HT40 you'll need at a regulatory rule that allows you to use 40 MHz channels but you're channel must also be enabled and support 20 MHz by itself. The second pass is done after we do the regulatory checks over an device's supported channel list. On each channel we'll check if the control channel and the extension both: o exist o are enabled o regulatory allows 40 MHz bandwidth on its frequency range This work allows allows us to idependently check for HT40- and HT40+.

Add a new NL80211_ATTR_CONTROL_PORT flag for NL80211_CMD_ASSOCIATE to allow user space to indicate that it will control the IEEE 802.1X port in station mode. Previously, mac80211 was always marking the port authorized in station mode. This was enough when drop_unencrypted flag was set. However, drop_unencrypted can currently be controlled only with WEXT and the current nl80211 design does not allow fully secure configuration. Fix this by providing a mechanism for user space to control the IEEE 802.1X port in station mode (i.e., do the same that we are already doing in AP mode). Signed-off-by:

It is currently not possible to modify station flags, but that capability would be very useful. This patch introduces a new nl80211 attribute that contains a set/mask for station flags, and updates the internal API (and mac80211) to mirror that. The new attribute is parsed before falling back to the old so that userspace can specify both (if it can) to work on all kernels. Signed-off-by:

Move key handling wireless extension ioctls from mac80211 to cfg80211 so that all drivers that implement the cfg80211 operations get wext compatibility. Note that this drops the SIOCGIWENCODE ioctl support for getting IW_ENCODE_RESTRICTED/IW_ENCODE_OPEN. This means that iwconfig will no longer report "Security mode:open" or "Security mode:restricted" for mac80211. However, what we displayed there (the authentication algo used) was actually wrong -- linux/wireless.h states that this setting is meant to differentiate between "Refuse non-encoded packets" and "Accept non-encoded packets". (Combined with "cfg80211: fix a couple of bugs with key ioctls". -- JWL) Signed-off-by:

NL80211_CMD_ASSOCIATE request must be able to indicate whether management frame protection (IEEE 802.11w) is being used. mac80211 was able to use MFP in client mode only with WEXT, but the new NL80211_ATTR_USE_MFP attribute will allow this to be done with nl80211, too. Since we are currently using nl80211 for MFP only with drivers that use user space SME, only MFP disabled and required values are used. However, the NL80211_ATTR_USE_MFP attribute is an enum that can be extended with MFP optional in the future, if that is needed with some drivers (e.g., if the RSN IE is generated by the driver).

Add new nl80211 attributes that can be used with NL80211_CMD_SET_WIPHY and NL80211_CMD_GET_WIPHY to manage fragmentation/RTS threshold and retry limits. Since these values are stored in struct wiphy, remove the local copy from mac80211 where feasible (frag & rts threshold). The retry limits are currently needed in struct ieee80211_conf, but these could be eventually removed since the driver should have access to the values in struct wiphy. Signed-off-by:

Trying to separate header files into net/wireless.h and net/cfg80211.h has been a source of confusion. Remove net/wireless.h (because there also is the linux/wireless.h) and subsume everything into net/cfg80211.h -- except the definitions for regulatory structures which get moved to a new header net/regulatory.h. The "new" net/cfg80211.h is now divided into sections. There are no real changes in this patch but code shuffling and some very minor documentation fixes. I have also, to make things reflect reality, put in a copyright line for Luis to net/regulatory.h since that is probably exclusively written by him but was formerly in a file that only had my copyright line.

This adds IBSS API along with (preliminary) wext handlers. The wext handlers can only do IBSS so you need to call them from your own wext handlers if the mode is IBSS. The nl80211 API requires * an SSID * a channel (frequency) for the case that a new IBSS has to be created It optionally supports * a flag to fix the channel * a fixed BSSID The cfg80211 code also takes care to leave the IBSS before the netdev is set down. If wireless extensions are used, it also caches values when the interface is down and instructs the driver to join when the interface is set up. Signed-off-by:

Define a new nl80211 event, NL80211_CMD_MICHAEL_MIC_FAILURE, to be used to notify user space about locally detected Michael MIC failures. This matches with the MLME-MICHAELMICFAILURE.indication() primitive. Since we do not actually have TSC in the skb anymore when mac80211_ev_michael_mic_failure() is called, that function is changed to take in the TSC as an optional parameter instead of as a requirement to include the TSC after the hdr field (which we did not really follow). For now, TSC is not included in the events from mac80211, but it could be added at some point. Signed-off-by:

Previously, nl80211 mlme events were generated only for received deauthentication and disassociation frames. We need to do the same for locally generated ones in order to let applications know that we disconnected (e.g., when AP does not reply to a probe). Rename the nl80211 and cfg80211 functions (s/rx_//) to make it clearer that they are used for both received and locally generated frames. Signed-off-by:

The functionality that NL80211_CMD_SET_MGMT_EXTRA_IE provided can now be achieved with cleaner design by adding IE(s) into NL80211_CMD_TRIGGER_SCAN, NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE, NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE. Since this is a very recently added command and there are no known (or known planned) applications using NL80211_CMD_SET_MGMT_EXTRA_IE and taken into account how much extra complexity it adds to the IE processing we have now (and need to add in the future to fix IE order in couple of frames), it looks like the best option is to just remove the implementation of this command for now. The enum values themselves are left to avoid changing the nl80211 command or attribute numbers. Signed-off-by:
