* cfg80211/mac80211: add wmm info to assoc eventEliad Peller2014-09-111-2/+2
| | | | | | | | | | | | | | | Userspace might need to know what queues are configured for uapsd (e.g. for setting proper default values in tspecs). Add this bitmap to the association event (inside wmm nested attribute) Add additional parameter to cfg80211_rx_assoc_resp, and update its callers.

* cfg80211: remove @gfp parameter from cfg80211_rx_mgmt()Vladimir Kondratiev2014-08-261-2/+2
| | | | | | | | | | | | | | In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation. But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code. Remove @gfp parameter as no actual choice exist, and use hard coded GFP_ATOMIC for memory allocation.

* cfg80211: consider existing DFS interfacesMichal Kazior2014-02-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | It was possible to break interface combinations in the following way: combo 1: iftype = AP, num_ifaces = 2, num_chans = 2, combo 2: iftype = AP, num_ifaces = 1, num_chans = 1, radar = HT20 With the above interface combinations it was possible to: step 1. start AP on DFS channel by matching combo 2 step 2. start AP on non-DFS channel by matching combo 1 This was possible beacuse (step 2) did not consider if other interfaces require radar detection. The patch changes how cfg80211 tracks channels - instead of channel itself now a complete chandef is stored.

* cfg80211: separate internal SME implementationJohannes Berg2013-06-041-131/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Berg2013-06-041-32/+54
| | | | | | | | | | | | | | | | | 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: remove some locked wrappers from mlme APIJohannes Berg2013-05-251-97/+23

* cfg80211/mac80211: use cfg80211 wdev mutex in mac80211Johannes Berg2013-05-251-40/+8
| | | | | | | | | | | | | | | 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 Berg2013-05-251-6/+6
| | | | | | | | | | | | | | | 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: introduce critical protocol indication from user-spaceArend van Spriel2013-04-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | Some protocols need a more reliable connection to complete successful in reasonable time. 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.

The advantage is reduced code, both source and binary, e.g. on x86-64 text data bss dec hex filename 442825 56230 776 499831 7a077 cfg80211.ko (before) 441585 56230 776 498591 79b9f cfg80211.ko (after) a reduction of ~1k.

* cfg80211: remove remain-on-channel channel typeJohannes Berg2012-11-261-15/+6
| | | | | | | | | | | | | | | | | As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

| | | | | | | | | | | | | | | | | | | | | | | In order to support using a different MAC address for the P2P Device address we must first have a P2P Device abstraction that can be assigned a MAC address.

Currently, the driver is responsible for assigning a MAC address to the P2P Device, but this could be changed by allowing a MAC address to be given to the NEW_INTERFACE command.

| | | | | | | | | | In "cfg80211: no cookies in cfg80211_send_XXX()" Holger Schurig removed the cookies in the calls from mac80211 to cfg80211, but the ones in the other direction were left in. Remove them now. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* cfg80211: stop tracking authenticated stateJohannes Berg2012-02-061-269/+53
| | | | | | | | | | | | | | | | | | | | | | | | | To track authenticated state seems to have been a design mistake in cfg80211. It is possible to have out of band authentication (FT), tracking multiple authentications caused more problems than it ever helped, and the implementation in mac80211 is too complex. Remove all this complexity, and let userspace do whatever it wants to, mac80211 can deal with that just fine. Association is still tracked of course, but authentication no longer is. Local auth state changes are thus no longer of value, so ignore them completely. This will also help implement SAE -- asking the driver to do an authentication is now almost equivalent to sending an authentication frame, with the exception of shared key authentication which is still handled completely.

* wireless: Support ht-capabilities over-rides.Ben Greear2011-11-211-3/+34
| | | | | | | | | | | | | | | | | | | | This allows users to disable features such as HT, HT40, and to modify the MCS, AMPDU, and AMSDU settings for drivers that support it. The MCS, AMPDU, and AMSDU features that may be disabled are are reported in the phy-info netlink message as a mask. Attemping to disable features that are not supported will take no affect, but will not return errors. This is to aid backwards compatibility in user-space apps that may not be clever enough to deal with parsing the the capabilities mask. This patch only enables the infrastructure. An additional patch will enable the feature in mac80211. Signed-off-by: Ben Greear <greearb@candelatech.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
