Add some information that we have about VHT to radiotap. This at least lets one see the MCS and NSS information. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-27mac80211: support VHT associationJohannes Berg1-0/+15
Determine the VHT channel from the AP's VHT operation IE (if present) and configure the hardware to that channel if it is supported. If channel contexts cause a channel to not be usable, try a smaller bandwidth. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-27cfg80211: rework chandef checking and export itJohannes Berg1-3/+18
Some of the chandef checking that we do in cfg80211 to check if a channel is supported or not is also needed in mac80211, so rework that a bit and export the functions that are needed. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-11-26nl80211/cfg80211: add VHT MCS supportJohannes Berg2-8/+28
Add support for reporting and calculating VHT MCSes. Note that I'm not completely sure that the bitrate calculations are correct, nor that they can't be simplified. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-26mac80211: convert to channel definition structJohannes Berg1-10/+7
Convert mac80211 (and where necessary, some drivers a little bit) to the new channel definition struct. This will allow extending mac80211 for VHT, which is currently restricted to channel contexts since there are no drivers using that which makes it easier. As I also don't care about VHT for drivers not using the channel context API, I won't convert the previous API to VHT support. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-26nl80211/cfg80211: support VHT channel configurationJohannes Berg2-13/+121
Change nl80211 to support specifying a VHT (or HT) using the control channel frequency (as before) and new attributes for the channel width and first and second center frequency. The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-26cfg80211: pass a channel definition structJohannes Berg1-30/+35
Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-11-26cfg80211: remove remain-on-channel channel typeJohannes Berg3-18/+8
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.

2012-11-26cfg80211: change function signature of cfg80211_get_p2p_attr()Arend van Spriel1-2/+3
The function cfg80211_get_p2p_attr() can fail and returns a negative error code. However, the return type is unsigned int. The largest positive number is determined by desired_len variable in the function, which is u16. So changing the return type to int to allow easy error checking. Also change the type for the attribute to enum for improved type checking.

2012-11-19mac80211: make remain_on_channel() op pass vif paramEliad Peller1-0/+1
Drivers (e.g. wl12xx) might need to know the vif to roc on (mainly in order to configure the rx filters correctly). Add the vif to the op params, and update the current users (iwlwifi) to use the new api.

2012-11-19cfg80211: Add TDLS event to allow drivers to request operationsJouni Malinen2-0/+25
The NL80211_CMD_TDLS_OPER command was previously used only for userspace request for the kernel code to perform TDLS operations. However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN). Drivers can optionally use these events, e.g., based on noticing data traffic being sent to a peer station that is seen with good signal strength.

2012-11-19mac80211: support radiotap vendor namespace RX dataJohannes Berg1-0/+12
In some cases, in particular for experimentation, it can be useful to be able to add vendor namespace data to received frames in addition to the normal radiotap data. Allow doing this through mac80211 by adding fields to the RX status descriptor that describe the data while the data itself is prepended to the frame. Also add some example code to hwsim, but don't enable it because it doesn't use a proper OUI identifier. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-19mac80211: introduce IEEE80211_NUM_TIDS and use itJohannes Berg1-0/+2
Introduce IEEE80211_NUM_TIDS in the generic 802.11 header file and use it in place of STA_TID_NUM and NUM_RX_DATA_QUEUES which are both really the number of TIDs. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-14mac80211: support RX_FLAG_MACTIME_ENDThomas Pedersen1-2/+6
Allow drivers to indicate their mactime is at RX completion and adjust for this in mac80211. Also rename the existing RX_FLAG_MACTIME_MPDU to RX_FLAG_MACTIME_START to clarify its intent.

2012-11-12nl/cfg80211: advertise OBSS scan requirementAmitkumar Karwar1-0/+4
wpa_supplicant will do OBSS scan for drivers that implement auth/assoc API. Drivers that implement nl80211 connect API (rather than auth/assoc) may need wpa_supplicant to do this as well. Add a new feature flag to inform it (wpa_s) that a driver needs wpa_supplicant to do OBSS scans.

2012-11-09mac80211: clarify interface iteration and make it configurableJohannes Berg1-2/+21
During hardware restart, all interfaces are iterated even though they haven't been re-added to the driver, document this behaviour. The same also happens during resume, which is even more confusing since all of the interfaces were previously removed from the driver. Make this optional so drivers relying on the current behaviour can still use it, but to let drivers that don't want this behaviour disable it. Also convert all API users, keeping the old semantics except in hwsim, where the new normal ones are desired. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-09mac80211: call driver method when restart completesJohannes Berg1-0/+6
When the driver requests a restart (reconfiguration) it gets all the normal method calls, but can't really tell why they're happening. Call a new restart_complete op in the driver when the restart completes, so it could keep its own state about the restart and clear it there. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-11-06mac80211: pass P2P powersave parameters to driverJohannes Berg1-0/+7

2012-11-06wireless: add utility function to get P2P attributeJohannes Berg1-0/+19
Parsing the P2P attributes can be tricky as their contents can be split across multiple (vendor) IEs. Thus, it's not possible to parse them like IEs (by returning a pointer to the data.) Instead, provide a function that copies the attribute data into a caller-provided buffer and returns the size needed (useful in case the buffer was too small.)

2012-10-30mac80211: handle TX power per virtual interfaceJohannes Berg1-1/+6
Even before channel contexts/multi-channel, having a single global TX power limit was already problematic, in particular if two managed interfaces connected to two APs with different power constraints. The channel context introduction completely broke this though and in fact I had disabled TX power configuration there for drivers using channel contexts. Change everything to track TX power per interface so that different user settings and different channel maxima are treated correctly. Also continue tracking the global TX power though for compatibility with applications that attempt to configure the wiphy's TX power globally. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-10-30cfg80211: allow per interface TX power settingJohannes Berg2-3/+9
The TX power setting is currently per wiphy (hardware device) but with multi-channel capabilities that doesn't make much sense any more. Allow drivers (and mac80211) to advertise support for per-interface TX power configuration. When the TX power is configured for the wiphy, the wdev will be NULL and the driver can still handle that, but when a wdev is given the TX power can be set only for that wdev now.
