* {nl,cfg}80211: make peer link expiration time configurableColleen Twitty2013-06-112-1/+9
| | | | | | | | | | | | | | If a STA has a peer that it hasn't seen any tx activity from for a certain length of time, the peer link is expired. This means the inactive STA is removed from the list of peers and that STA is not considered a peer again unless it re-peers. Previously, this inactivity time was always 30 minutes. Now, add it to the mesh configuration and allow it to be configured. Retain 30 minutes as a default value.

* cfg80211: make wiphy index start at 0 againJohannes Berg2013-06-041-0/+3
| | | | | | | | | The change to use atomic_inc_return() for assigning the wiphy index made the first wiphy index 1 instead of 0. This is fine, but we all habitually type "phy0" when we're testing, so make it go back to 0 instead of 1 by subtracting 1 from the index. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* cfg80211: fix potential deadlock regressionJohannes Berg2013-06-041-15/+8Star
| | | | | | | | | | | | | My big locking cleanups caused a problem by registering the rfkill instance with the RTNL held, while the callback also acquires the RTNL. This potentially causes a deadlock since the two locks used (rfkill mutex and RTNL) can be acquired in two different orders. Fix this by (un)registering rfkill without holding the RTNL. This needs to be done after the device struct is registered, but that can also be done w/o holding the RTNL. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

* cfg80211: separate internal SME implementationJohannes Berg2013-06-047-448/+335Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The current internal SME implementation in cfg80211 is very mixed up with the MLME handling, which has been causing issues for a long time. There are three things that the implementation has to provide: * a basic SME implementation for nl80211's connect() call (for drivers implementing auth/assoc, which is really just mac80211) and wireless extensions * MLME events for the userspace SME * SME events (connected, disconnected etc.) for all different SME implementation possibilities (driver, cfg80211 and userspace) To achieve these goals it isn't necessary to track the software SME's connection status outside of it's state (which is the part that caused many issues.) Instead, track it only in the SME data (wdev->conn) and in the general case only track whether the wdev is connected or not (via wdev->current_bss.) Also separate the internal implementation to not have callbacks from the SME events, but rather call it from the API functions that the driver (or rather mac80211) calls. This separates the code better. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
* cfg80211/mac80211: clean up cfg80211 SME APIsJohannes Berg2013-06-043-61/+101
| | | | | | | | | | | | | | | | | Do some cleanups in the cfg80211 SME APIs, which are only used by mac80211. Most of these functions get a frame passed, and there isn't really any reason to export multiple functions as cfg80211 can check the frame type instead, do that. Additionally, the API functions have confusing names like cfg80211_send_...() which was meant to indicate that it sends an event to userspace, but gets a bit confusing when there's both TX and RX and they're not all clearly labeled.

* cfg80211/mac80211: use cfg80211 wdev mutex in mac80211Johannes Berg2013-05-252-42/+10Star
| | | | | | | | | | | | | | | Using separate locks in cfg80211 and mac80211 has always caused issues, for example having to unlock in places in mac80211 to call cfg80211, which even needed a framework to make cfg80211 calls after some functions returned etc. Additionally, I suspect some issues people have reported with the cfg80211 state getting confused could be due to such issues, when cfg80211 is asking mac80211 to change state but mac80211 is in the process of telling cfg80211 that the state changed (in another way.)

* cfg80211: vastly simplify lockingJohannes Berg2013-05-2513-444/+115Star
| | | | | | | | | | | | | | | Virtually all code paths in cfg80211 already (need to) hold the RTNL. As such, there's little point in having another four mutexes for various parts of the code, they just cause lock ordering issues (and much of the time, the RTNL and a few of the others need thus be held.) Simplify all this by getting rid of the extra four mutexes and just use the RTNL throughout. Only a few code changes were needed to do this and we can get rid of a work struct for bonus points.

* | cfg80211: Allow TDLS peer AID to be configured for VHTJouni Malinen2013-05-241-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current design for TDLS is to first add a dummy STA entry before completing TDLS Setup and then update information on this STA entry based on what was received from the peer during the setup exchange. In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just like this is used in AP mode to set the AID of an association station. However, existing cfg80211 validation rules prevent this attribute from being used with set_station operation. To avoid interoperability issues between different kernel and user space version combinations, introduce a new nl80211 attribute for the purpose of setting TDLS peer AID. This attribute can be used in both the new_station and set_station operations. It is not supposed to be allowed to change the AID value during the lifetime of the STA entry, but that validation is left for drivers to do in the change_station callback.

This patch adds a user-space API to indicate the wireless driver that a critical protocol is about to commence and when it is done, using nl80211 primitives NL80211_CMD_CRIT_PROTOCOL_START and NL80211_CRIT_PROTOCOL_STOP. There can be only on critical protocol session started per registered cfg80211 device. The driver can support this by implementing the cfg80211 callbacks .crit_proto_start() and .crit_proto_stop(). Examples of protocols that can benefit from this are DHCP, EAPOL, APIPA. Exactly how the link can/should be made more reliable is up to the driver. Things to consider are avoid scanning, no multi-channel operations, and alter coexistence schemes.

Then, when the driver checks if it should do a passive scan, that will return false and attempt an active scan. This is not only wrong but can also lead to the iwlwifi device firmware crashing since it checks regulatory as well. Fix this by not setting the channel flags to just disabled but rather OR'ing in the disabled flag. That way, even if the race happens, the channel will be scanned passively which is still (mostly) correct. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>
