2021-08-17nl80211: add support for BSS coloringJohn Crispin1-0/+43
This patch adds support for BSS color collisions to the wireless subsystem. Add the required functionality to nl80211 that will notify about color collisions, triggering the color change and notifying when it is completed.

2021-06-23cfg80211: allow advertising vendor-specific capabilitiesJohannes Berg1-0/+3
There may be cases where vendor-specific elements need to be used over the air. Rather than have driver or firmware add them and possibly cause problems that way, add them to the iftype-data band capabilities. This way we can advertise to userspace first, and use them in mac80211 next.

2020-12-11nl80211: add common API to configure SAR power limitationsCarl Huang1-0/+105
NL80211_CMD_SET_SAR_SPECS is added to configure SAR from user space. NL80211_ATTR_SAR_SPEC is used to pass the SAR power specification when used with NL80211_CMD_SET_SAR_SPECS. Wireless driver needs to register SAR type, supported frequency ranges to wiphy, so user space can query it. The index in frequency range is used to specify which sub band the power limitation applies to. The SAR type is for compatibility, so later other SAR mechanism can be implemented without breaking the user space SAR applications. Normal process is user space queries the SAR capability, and gets the index of supported frequency ranges and associates the power limitation with this index and sends to kernel. Here is an example of message send to kernel: 8c 00 00 00 08 00 01 00 00 00 00 00 38 00 2b 81 08 00 01 00 00 00 00 00 2c 00 02 80 14 00 00 80 08 00 02 00 00 00 00 00 08 00 01 00 38 00 00 00 14 00 01 80 08 00 02 00 01 00 00 00 08 00 01 00 48 00 00 00 NL80211_CMD_SET_SAR_SPECS: 0x8c NL80211_ATTR_WIPHY: 0x01(phy idx is 0) NL80211_ATTR_SAR_SPEC: 0x812b (NLA_NESTED) NL80211_SAR_ATTR_TYPE: 0x00 (NL80211_SAR_TYPE_POWER) NL80211_SAR_ATTR_SPECS: 0x8002 (NLA_NESTED) freq range 0 power: 0x38 in 0.25dbm unit (14dbm) freq range 1 power: 0x48 in 0.25dbm unit (18dbm) Signed-off-by: Carl Huang <cjhuang@codeaurora.org> Reviewed-by: Brian Norris <briannorris@chromium.org> Reviewed-by: Abhishek Kumar <kuabhs@chromium.org> Link: https://lore.kernel.org/r/20201203103728.3034-2-cjhuang@codeaurora.org [minor edits, NLA parse cleanups] Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Add support to configure SAE PWE preference from userspace to drivers in both AP and STA modes. This is needed for cases where the driver takes care of Authentication frame processing (SME in the driver) so that correct enforcement of the acceptable PWE derivation mechanism can be performed. The userspace applications can pass the sae_pwe value using the NL80211_ATTR_SAE_PWE attribute in the NL80211_CMD_CONNECT and NL80211_CMD_START_AP commands to the driver. This allows selection between the hunting-and-pecking loop and hash-to-element options for PWE derivation. For backwards compatibility, this new attribute is optional and if not included, the driver is notified of the value being unspecified.

2020-08-27nl80211: fix PORT_AUTHORIZED wording to reflect behaviorJames Prestwood1-13/+7
The CMD_PORT_AUTHORIZED event was described as an event which indicated a successfully completed 4-way handshake. But the behavior was not as advertized. The only driver which uses this is brcmfmac, and this driver only sends the event after a successful 802.1X-FT roam. This prevents userspace applications from knowing if the 4-way completed on: 1. Normal 802.1X connects 2. Normal PSK connections 3. FT-PSK roams wpa_supplicant handles this incorrect behavior by just completing the connection after association, before the 4-way has completed. If the 4-way ends up failing it disconnects at that point. Since this behavior appears to be expected (wpa_s handles it this way) I have changed the wording in the API description to reflect the actual behavior.

2020-07-31cfg80211/mac80211: add mesh_param "mesh_nolearn" to skip path discoveryLinus Lüssing1-0/+7
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.

These capabilities cover what would otherwise be transported in HT/VHT capabilities, but only a subset thereof that is actually needed on 6 GHz with HE already present. Expose the capabilities to userspace, drivers are expected to set them as using the 6 GHz band (currently) requires HE capability.

If the driver advertises NL80211_EXT_FEATURE_SCAN_FREQ_KHZ userspace can omit NL80211_ATTR_SCAN_FREQUENCIES in favor of an NL80211_ATTR_SCAN_FREQ_KHZ. To get scan results in KHz userspace must also set the NL80211_SCAN_FLAG_FREQ_KHZ. This lets nl80211 remain compatible with older userspaces while not requring and sending redundant (and potentially incorrect) scan frequency sets.

2020-05-27nl80211: simplify peer specific TID configurationSergey Matyukevich1-6/+4
Current rule for applying TID configuration for specific peer looks overly complicated. No need to reject new TID configuration when override flag is specified. Another call with the same TID configuration, but without override flag, allows to apply new configuration anyway. Use the same approach as for the 'all peers' case: if override flag is specified, then reset existing TID configuration and immediately apply a new one.

2020-03-20cfg80211: Configure PMK lifetime and reauth threshold for PMKSA entriesVeerendranath Jakkam1-0/+27
Drivers that trigger roaming need to know the lifetime of the configured PMKSA for deciding whether to trigger the full or PMKSA cache based authentication. The configured PMKSA is invalid after the PMK lifetime has expired and must not be used after that and the STA needs to disassociate if the PMK expires. Hence the STA is expected to refresh the PMK with a full authentication before this happens (e.g., when reassociating to a new BSS the next time or by performing EAPOL reauthentication depending on the AKM) to avoid unnecessary disconnection. The PMK reauthentication threshold is the percentage of the PMK lifetime value and indicates to the driver to trigger a full authentication roam (without PMKSA caching) after the reauthentication threshold time, but before the PMK timer has expired. Authentication methods like SAE need to be able to generate a new PMKSA entry without having to force a disconnection after this threshold timeout. If no roaming occurs between the reauthentication threshold time and PMK lifetime expiration, disassociation is still forced. The new attributes for providing these values correspond to the dot11 MIB variables dot11RSNAConfigPMKLifetime and dot11RSNAConfigPMKReauthThreshold. This type of functionality is already available in cases where user space component is in control of roaming. This commit extends that same capability into cases where parts or all of this functionality is offloaded to the driver.

2020-03-20cfg80211: Add support for userspace to reset stations in IBSS modeNicolas Cavallari1-0/+4
Sometimes, userspace is able to detect that a peer silently lost its state (like, if the peer reboots). wpa_supplicant does this for IBSS-RSN by registering for auth/deauth frames, but when it detects this, it is only able to remove the encryption keys of the peer and close its port. However, the kernel also hold other state about the station, such as BA sessions, probe response parameters and the like. They also need to be resetted correctly. This patch adds the NL80211_EXT_FEATURE_DEL_IBSS_STA feature flag indicating the driver accepts deleting stations in IBSS mode, which should send a deauth and reset the state of the station, just like in mesh point mode.
