* nl80211: add power save commandsKalle Valo2010-02-191-3/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The most needed command from nl80211, which Wireless Extensions had, is support for power save mode. Add a simple command to make it possible to enable and disable power save via nl80211. I was also planning about extending the interface, for example adding the timeout value, but after thinking more about this I decided not to do it. Basically there were three reasons: Firstly, the parameters for power save are very much hardware dependent. Trying to find a unified interface which would work with all hardware, and still make sense to users, will be very difficult. Secondly, IEEE 802.11 power save implementation in Linux is still in state of flux. We have a long way to still to go and there is no way to predict what kind of implementation we will have after few years. And because we need to support nl80211 interface a long time, practically forever, adding now parameters to nl80211 might create maintenance problems later on. Third issue are the users. Power save parameters are mostly used for debugging, so debugfs is better, more flexible, interface for this. For example, wpa_supplicant currently doesn't configure anything related to power save mode. It's better to strive that kernel can automatically optimise the power save parameters, like with help of pm qos network and other traffic parameters. Later on, when we have better understanding of power save, we can extend this command with more features, if there's a need for that.

* cfg80211/mac80211: allow registering for and sending action framesJouni Malinen2010-02-151-1/+46
| | | | | | | | | | | | | | | | | | | | | | | This implements a new command to register for action frames that userspace wants to handle instead of the in-kernel rejection. It is then responsible for rejecting ones that it decided not to handle. There is no unregistration, but the socket can be closed for that. Frames that are not registered for will not be forwarded to userspace and will be rejected by the kernel, the cfg80211 API helps implementing that. Additionally, this patch adds a new command that allows doing action frame transmission from userspace. It can be used either to exchange action frames on the current operational channel (e.g., with the AP with which we are currently associated) or to exchange off-channel Public Action frames with the remain-on-channel command.

* cfg80211: export multiple MAC addresses in sysfsJohannes Berg2010-01-221-1/+21
| | | | | | | | | | | | | | | | | | | | If a device has multiple MAC addresses, userspace will need to know about that. Similarly, if it allows the MAC addresses to vary by a bitmask. If a driver exports multiple addresses, it is assumed that it will be able to deal with that many different addresses, which need not necessarily match the ones programmed into the device; if a mask is set then the device should deal addresses within that mask based on an arbitrary "base address". To test it all and show how it is used, add support to hwsim even though it can't actually deal with addresses different from the default.

* cfg80211: Store IEs from both Beacon and Probe Response framesJouni Malinen2010-01-121-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Store information elements from Beacon and Probe Response frames in separate buffers to allow both sets to be made available through nl80211. This allows user space applications to get access to IEs from Beacon frames even if we have received Probe Response frames from the BSS. Previously, the IEs from Probe Response frames would have overridden the IEs from Beacon frames. This feature is of somewhat limited use since most protocols include the same (or extended) information in Probe Response frames. However, there are couple of exceptions where the IEs from Beacon frames could be of some use: TIM IE is only included in Beacon frames (and it would be needed to figure out the DTIM period used in the BSS) and at least some implementations of Wireless Provisioning Services seem to include the full IE only in Beacon frames). The new BSS attribute for scan results is added to allow both the IE sets to be delivered. This is done in a way that maintains the previously used behavior for applications that are not aware of the new NL80211_BSS_BEACON_IES attribute.

* nl80211: New command for setting TX rate mask for rate controlJouni Malinen2010-01-121-2/+2
| | | | | | | | | | | | | Add a new NL80211_CMD_SET_TX_BITRATE_MASK command and related attributes to provide support for setting TX rate mask for rate control. This uses the existing cfg80211 set_bitrate_mask operation that was previously used only with WEXT compat code (SIOCSIWRATE). The nl80211 command allows more generic configuration of allowed rates as a mask instead of fixed/max rate.

* cfg80211/mac80211: Use more generic bitrate mask for rate controlJouni Malinen2010-01-121-11/+2Star
| | | | | | | | | | | | | | | | | | | | | | Extend struct cfg80211_bitrate_mask to actually use a bitfield mask instead of just a single fixed or maximum rate index. This change itself does not modify the behavior (except for debugfs files), but it prepares cfg80211 and mac80211 for a new nl80211 command for setting which rates can be used in TX rate control. Since frames are now going through the rate control algorithm unconditionally, the internal IEEE80211_TX_INTFL_RCALGO flag can now be removed. The RC implementations can use the rate_idx_mask value to optimize their behavior if only a single rate is enabled. The old max_rate_idx in struct ieee80211_tx_rate_control is maintained (but commented as deprecated) for backwards compatibility with existing RC implementations. Once these implementations have been updated to use the more generic rate_idx_mask, the max_rate_idx value can be removed.

| | | | | | | | | | | | | | | | | | | | | Add new commands for requesting the driver to remain awake on a specified channel for the specified amount of time (and another command to cancel such an operation). This can be used to implement userspace-controlled off-channel operations, like Public Action frame exchange on another channel than the operation channel. The off-channel operation should behave similarly to scan, i.e. the local station (if associated) moves into power save mode to request the AP to buffer frames for it and then moves to the other channel to allow the off-channel operation to be completed. The duration parameter can be used to request enough time to receive a response from the target station.

* mac80211: avoid spurious deauth frames/messagesJohannes Berg2009-11-191-0/+12
| | | | | | | | | | | | | | | | | | | With WEXT, it happens frequently that the SME requests an authentication but then deauthenticates right away because some new parameters came along. Every time this happens we print a deauth message and send a deauth frame, but both of that is rather confusing. Avoid it by aborting the authentication process silently, and telling cfg80211 about that. The patch looks larger than it really is: __cfg80211_auth_remove() is split out from cfg80211_send_auth_timeout(), there's no new code except __cfg80211_auth_canceled() (a one-liner) and the mac80211 bits (7 new lines of code).

Also, keep track of 4addr in cfg80211 (wireless_dev) and not in mac80211 any more. mac80211 can also be improved for the VLAN case by not looking at the 4addr flag but maintaining the station pointer for it correctly.

The goal of this command is to allow a drivers to report channel survey data (e.g. channel noise, channel occupation). For now, only the mechanism to report back channel noise has been implemented. In future, there will either be a survey-trigger command --- or the existing scan-trigger command will be enhanced. This will allow user-space to request survey for arbitrary channels. Note: any driver that cannot report channel noise should not report any value at all, e.g. made-up -92 dBm. Signed-off-by: Holger Schurig <holgerschurig@gmail.com> Signed-off-by: John W.

This adds them back, but only for wireless extensions. With the userspace SME, it shall control assoc vs. reassoc (it already can do so with the nl80211 interface). I haven't touched the connect() implementation, so it is not possible to reassociate with the nl80211 connect primitive. I think that should be done with the NL80211_CMD_ROAM command, but we'll have to see how that can be handled in the future, especially with fullmac chips.

This patch fixes firmware issues picked up by iwlwifi when we lift passive scan of beaconing restrictions on channels its EEPROM has been configured to always enable. By doing so though we also disallowed beacon hints on devices registering their wiphy with custom world regulatory domains enabled, this happens to be currently ath5k, ath9k and ar9170. The passive scan and beacon restrictions on those devices would never be lifted even if we did find a beacon and the hardware did support such enhancements when world roaming. Since Johannes indicates iwlwifi firmware cannot be changed to allow beacon hinting we set up a flag now to specifically allow drivers to disable beacon hints for devices which cannot use them. We enable the flag on iwlwifi to disable beacon hints and by default enable it for all other drivers. It should be noted beacon hints lift passive scan flags and beacon restrictions when we receive a beacon from an AP on any 5 GHz non-DFS channels, and channels 12-14 on the 2.4 GHz band. We don't bother with channels 1-11 as those channels are allowed world wide. This should fix world roaming for ath5k, ath9k and ar9170, thereby improving scan time when we receive the first beacon from any AP, and also enabling beaconing operation (AP/IBSS/Mesh) on cards which would otherwise not be allowed to do so. Drivers not using custom regulatory stuff (wiphy_apply_custom_regulatory()) were not affected by this as the orig_flags for the channels would have been cleared upon wiphy registration. I tested this with a world roaming ath5k card. Cc: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: Luis R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over time, a lot of locking issues have crept into the smarts of cfg80211, so e.g. scan completion can race against a new scan, IBSS join can race against leaving an IBSS, etc. Introduce a new per-interface lock that protects most of the per-interface data that we need to keep track of, and sprinkle assertions about that lock everywhere. Some things now need to be offloaded to work structs so that we don't require being able to sleep in functions the drivers call. The exception to that are the MLME callbacks (rx_auth etc.) that currently only mac80211 calls because it was easier to do that there instead of in cfg80211, and future drivers implementing those calls will, if they ever exist, probably need to use a similar scheme like mac80211 anyway... In order to be able to handle _deauth and _disassoc properly, introduce a cookie passed to it that will determine locking requirements.

* | cfg80211: mlme API must be able to sleepJohannes Berg2009-07-101-16/+14Star
| | | | | | | | | | | | | | | | | | After the mac80211 mlme cleanup, we can require that the MLME functions in cfg80211 can sleep. This will simplify future work in cfg80211 a lot. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | cfg80211: dont use union for wextJohannes Berg2009-07-101-4/+2Star
| | | | | | | | | | | | | | | | | | Otherwise it becomes very hard to reset the structs correctly since wext can be configured while the interface is down. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | cfg80211: let SME control reassociation vs. associationJohannes Berg2009-07-101-1/+2
| | | | | | | | | | | | | | | | | | | | Since we don't really know that well in the kernel, let's let the SME control whether it wants to use reassociation or not, by allowing it to give the previous BSSID in the associate() parameters.

* | cfg80211: keep track of BSSesJohannes Berg2009-07-101-64/+22Star
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | This function from mac80211 seems generally useful, and I will need it in cfg80211 soon. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* | cfg80211: implement get_wireless_statsJohannes Berg2009-07-101-0/+1
| | | | | | | | | | | | | | | | | | | | 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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* | cfg80211: implement IWRATEJohannes Berg2009-07-101-0/+32
| | | | | | | | | | | | | | | | | | | | 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: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W. Linville <linville@tuxdriver.com>

* | cfg80211: implement iwpowerJohannes Berg2009-07-101-0/+13
| | | | | | | | | | | | | | | | | | 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.

* | cfg80211: managed mode wext compatibilityJohannes Berg2009-07-101-1/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | cfg80211: emulate connect with auth/assocJohannes Berg2009-07-101-1/+5
| | | | | | | | | | | | | | | | | | | | | | 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: Samuel Ortiz <samuel.ortiz@intel.com> Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
