2022-01-04nl80211: clarify comment for mesh PLINK_BLOCKED stateGravatar Felix Fietkau 1-1/+1
When a mesh link is in blocked state, it is very useful to still allow auth requests from the peer to re-establish it. When a remote node is power cycled, the peer state can easily end up in blocked state if multiple auth attempts are performed. Since this can lead to several minutes of downtime, we should accept auth attempts of the peer after it has come back.

2021-12-20nl80211: Add support to offload SA Query procedures for AP SME deviceGravatar Veerendranath Jakkam 1-4/+12
Add a flag attribute to use in ap settings to indicate userspace supports offloading of SA Query procedures to driver. Also add AP SME device feature flag to advertise that the SA Query procedures offloaded to driver when userspace indicates support for offloading of SA Query procedures. Driver handles SA Query procedures in driver's SME it self and skip sending SA Query request or response frames to userspace when userspace indicates support for SA Query procedures offload. But if userspace doesn't advertise support for SA Query procedures offload driver shall not offload SA Query procedures handling. Also userspace with SA Query procedures offload capability shall skip SA Query specific validations when driver indicates support for handling SA Query procedures.

Add a driver FILS crypto offload extended capability flag to indicate that the driver running in AP mode is capable of handling encryption and decryption of (Re)Association request and response frames. Add a command to set FILS AAD data to driver. This feature is supported on drivers running in AP mode only. This extended capability is exchanged with hostapd during cfg80211 init. If the driver indicates this capability, then before sending the Authentication response frame, hostapd sets FILS AAD data to the driver.

2020-12-11nl80211: add common API to configure SAR power limitationsGravatar Carl Huang 1-0/+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>

2020-11-06cfg80211: Add support to configure SAE PWE value to driversGravatar Rohan Dutta 1-0/+26
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 behaviorGravatar James Prestwood 1-13/+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 discoveryGravatar Linus Lüssing 1-0/+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.
