2020-07-31cfg80211: invert HE BSS color 'disabled' to 'enabled'Johannes Berg1-1/+1
This is in fact 'disabled' in the spec, but there it's in a place where that actually makes sense. In our internal data structures, it doesn't really make sense, and in fact the previous commit just fixed a bug in that area. Make this safer by inverting the polarity from 'disabled' to 'enabled'.

2020-07-31cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path discoveryLinus Lüssing1-0/+2
Currently, before being able to forward a packet between two 802.11s nodes, both a PLINK handshake is performed upon receiving a beacon and then later a PREQ/PREP exchange for path discovery is performed on demand upon receiving a data frame to forward. When running a mesh protocol on top of an 802.11s interface, like batman-adv, we do not need the multi-hop mesh routing capabilities of 802.11s and usually set mesh_fwding=0. However, even with mesh_fwding=0 the PREQ/PREP path discovery is still performed on demand. Even though in this scenario the next hop PREQ/PREP will determine is always the direct 11s neighbor node. The new mesh_nolearn parameter allows to skip the PREQ/PREP exchange in this scenario, leading to a reduced delay, reduced packet buffering and simplifies HWMP in general. mesh_nolearn is still rather conservative in that if the packet destination is not a direct 11s neighbor, it will fall back to PREQ/PREP path discovery. For normal, multi-hop 802.11s mesh routing it is usually not advisable to enable mesh_nolearn as a transmission to a direct but distant neighbor might be worse than reaching that same node via a more robust / higher throughput etc. multi-hop path.

2020-04-24mac80211: handle channel frequency offsetThomas Pedersen1-0/+6
cfg80211_chan_def and ieee80211_channel recently gained a frequency offset component. Handle this where it makes sense (potentially required by S1G channels). For IBSS, TDLS, CSA, and ROC we return -EOPNOTSUPP if a channel with frequency offset is passed, since they may or may not work. Once someone tests and verifies these commands work on thos types of channels, we can remove that error. join_ocb and join_mesh look harmless because they use a simple ieee80211_vif_use_channel(), which is using an already verified channel, so we let those through.

2020-04-24cfg80211: change internal management frame registration APIJohannes Berg1-29/+21
Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.

2020-02-07mac80211: use more bits for ack_frame_idJohannes Berg1-1/+1
It turns out that this wasn't a good idea, I hit a test failure in hwsim due to this. That particular failure was easily worked around, but it raised questions: if an AP needs to, for example, send action frames to each connected station, the current limit is nowhere near enough (especially if those stations are sleeping and the frames are queued for a while.) Shuffle around some bits to make more room for ack_frame_id to allow up to 8192 queued up frames, that's enough for queueing 4 frames to each connected station, even at the maximum of 2007 stations on a single AP. We take the bits from band (which currently only 2 but I leave 3 in case we add another band) and from the hw_queue, which can only need 4 since it has a limit of 16 queues.

2019-11-08mac80211: Shrink the size of ack_frame_id to make room for tx_time_estToke Høiland-Jørgensen1-1/+1
To implement airtime queue limiting, we need to keep a running account of the estimated airtime of all skbs queued into the device. Do to this correctly, we need to store the airtime estimate into the skb so we can decrease the outstanding balance when the skb is freed. This means that the time estimate must be stored somewhere that will survive for the lifetime of the skb. To get this, decrease the size of the ack_frame_id field to 6 bits, and lower the size of the ID space accordingly. This leaves 10 bits for use for tx_time_est, which is enough to store a maximum of 4096 us, if we shift the values so they become units of 4us.

2019-09-11mac80211: Do not send Layer 2 Update frame before authorizationJouni Malinen1-10/+4
The Layer 2 Update frame is used to update bridges when a station roams to another AP even if that STA does not transmit any frames after the reassociation. This behavior was described in IEEE Std 802.11F-2003 as something that would happen based on MLME-ASSOCIATE.indication, i.e., before completing 4-way handshake. However, this IEEE trial-use recommended practice document was published before RSN (IEEE Std 802.11i-2004) and as such, did not consider RSN use cases. Furthermore, IEEE Std 802.11F-2003 was withdrawn in 2006 and as such, has not been maintained amd should not be used anymore. Sending out the Layer 2 Update frame immediately after association is fine for open networks (and also when using SAE, FT protocol, or FILS authentication when the station is actually authenticated by the time association completes). However, it is not appropriate for cases where RSN is used with PSK or EAP authentication since the station is actually fully authenticated only once the 4-way handshake completes after authentication and attackers might be able to use the unauthenticated triggering of Layer 2 Update frame transmission to disrupt bridge behavior. Fix this by postponing transmission of the Layer 2 Update frame from station entry addition to the point when the station entry is marked authorized. Similarly, send out the VLAN binding update only if the STA entry has already been authorized.

2019-06-20net/mac80211: move WEP handling to ARC4 library interfaceArd Biesheuvel1-2/+2
The WEP code in the mac80211 subsystem currently uses the crypto API to access the arc4 (RC4) cipher, which is overly complicated, and doesn't really have an upside in this particular case, since ciphers are always synchronous and therefore always implemented in software. Given that we have no accelerated software implementations either, it is much more straightforward to invoke a generic library interface directly.

2019-06-14mac80211: use STA info in rate_control_send_low()Johannes Berg1-2/+2
Even if we have a station, we currently call rate_control_send_low() with the NULL station unless further rate control (driver, minstrel) has been initialized. Change this so we can use more information about the station to use a better rate. For example, when we associate with an AP, we will now use the lowest rate it advertised as supported (that we can) rather than the lowest mandatory rate. This aligns our behaviour with most other 802.11 implementations. To make this possible, we need to also ensure that we have non-zero rates at all times, so in case we really have *nothing* pre-fill the supp_rates bitmap with the very lowest mandatory bitmap (11b and 11a on 2.4 and 5 GHz respectively). Additionally, hostapd appears to be giving us an empty supported rates bitmap (it can and should do better, since the STA must have supported for at least the basic rates in the BSS), so ignore any such bitmaps that would actually zero out the supp_rates, and in that case just keep the pre-filled mandatory rates.

2019-04-26mac80211: probe unexercised mesh linksRajkumar Manoharan1-0/+1
The requirement for mesh link metric refreshing, is that from one mesh point we be able to send some data frames to other mesh points which are not currently selected as a primary traffic path, but which are only 1 hop away. The absence of the primary path to the chosen node makes it necessary to apply some form of marking on a chosen packet stream so that the packets can be properly steered to the selected node for testing, and not by the regular mesh path lookup.

2019-02-15mac80211: Restore vif beacon interval if start ap failsRakesh Pillai1-1/+5
The starting of AP interface can fail due to invalid beacon interval, which does not match the minimum gcd requirement set by the wifi driver. In such case, the beacon interval of that interface gets updated with that invalid beacon interval. The next time that interface is brought up in AP mode, an interface combination check is performed and the beacon interval is taken from the previously set value. In a case where an invalid beacon interval, i.e. a beacon interval value which does not satisfy the minimum gcd criteria set by the driver, is set, all the subsequent trials to bring that interface in AP mode will fail, even if the subsequent trials have a valid beacon interval. To avoid this, in case of a failure in bringing up an interface in AP mode due to interface combination error, the interface beacon interval which is stored in bss conf, needs to be restored with the last working value of beacon interval. Tested on ath10k using WCN3990.
