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.

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.

2020-03-20nl80211: add no pre-auth attribute and ext. feature flag for ctrl. portMarkus Theil1-1/+12
If the nl80211 control port is used before this patch, pre-auth frames (0x88c7) are send to userspace uncoditionally. While this enables userspace to only use nl80211 on the station side, it is not always useful for APs. Furthermore, pre-auth frames are ordinary data frames and not related to the control port. Therefore it should for example be possible for pre-auth frames to be bridged onto a wired network on AP side without touching userspace. For backwards compatibility to code already using pre-auth over nl80211, this patch adds a feature flag to disable this behavior, while it remains enabled by default. An additional ext. feature flag is added to detect this from userspace. Thanks to Jouni for pointing out, that pre-auth frames should be handled as ordinary data frames.

This reverts commit 8c3ed7aa2b9ef666195b789e9b02e28383243fa8. As Jouni points out, there's really no need for this, since the RSN pre-authentication frames are normal data frames, not port control frames (locally).

2020-02-07nl80211: add src and dst addr attributes for control port tx/rxMarkus Theil1-1/+15
When using control port over nl80211 in AP mode with pre-authentication, APs need to forward frames to other APs defined by their MAC address. Before this patch, pre-auth frames reaching user space over nl80211 control port have no longer any information about the dest attached, which can be used for forwarding to a controller or injecting the frame back to a ethernet interface over a AF_PACKET socket. Analog problems exist, when forwarding pre-auth frames from AP -> STA. This patch therefore adds the NL80211_ATTR_DST_MAC and NL80211_ATTR_SRC_MAC attributes to provide more context information when forwarding. The respective arguments are optional on tx and included on rx. Therefore unaware existing software is not affected. Software which wants to detect this feature, can do so by checking against: NL80211_EXT_FEATURE_CONTROL_PORT_OVER_NL80211_MAC_ADDRS Signed-off-by: Markus Theil <markus.theil@tu-ilmenau.de> Link: https://lore.kernel.org/r/20200115125522.3755-1-markus.theil@tu-ilmenau.de [split into separate cfg80211/mac80211 patches] Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2020-02-07cfg80211: Enhance the AKM advertizement to support per interface.Veerendranath Jakkam1-0/+33
Commit ab4dfa20534e ("cfg80211: Allow drivers to advertise supported AKM suites") introduces the support to advertize supported AKMs to userspace. This needs an enhancement to advertize the AKM support per interface type, specifically for the cfg80211-based drivers that implement SME and use different mechanisms to support the AKM's for each interface type (e.g., the support for SAE, OWE AKM's take different paths for such drivers on STA/AP mode). This commit aims the same and enhances the earlier mechanism of advertizing the AKMs per wiphy. Add new nl80211 attributes and data structure to provide supported AKMs per interface type to userspace. the AKMs advertized in akm_suites are default capabilities if not advertized for a specific interface type in iftype_akm_suites.

2019-12-13mac80211: Turn AQL into an NL80211_EXT_FEATUREToke Høiland-Jørgensen1-0/+5
Instead of just having an airtime flag in debugfs, turn AQL into a proper NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so we also expose the presence of the feature to userspace. This also has the effect of flipping the default, so drivers have to opt in to using AQL instead of getting it by default with TXQs. To keep functionality the same as pre-patch, we set this feature for ath10k (which is where it is needed the most). While we're at it, split out the debugfs interface so AQL gets its own per-station debugfs file instead of using the 'airtime' file. [Johannes:] This effectively disables AQL for iwlwifi, where it fixes a number of issues: * TSO in iwlwifi is causing underflows and associated warnings in AQL * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

2019-11-08cfg80211: VLAN offload support for set_key and set_sta_vlanGurumoorthi Gnanasambandhan1-0/+26
This provides an alternative mechanism for AP VLAN support where a single netdev is used with VLAN tagged frames instead of separate netdevs for each VLAN without tagged frames from the WLAN driver. By setting NL80211_EXT_FEATURE_VLAN_OFFLOAD flag the driver indicates support for a single netdev with VLAN tagged frames. Separate VLAN-specific netdevs can be added using RTM_NEWLINK/IFLA_VLAN_ID similarly to Ethernet. NL80211_CMD_NEW_KEY (for group keys), NL80211_CMD_NEW_STATION, and NL80211_CMD_SET_STATION will optionally specify vlan_id using NL80211_ATTR_VLAN_ID.

2019-10-04nl80211: Document the expectation for NL80211_ATTR_IE in NL80211_CMD_CONNECTSunil Dutt1-0/+8
This commit documents the expectation for NL80211_ATTR_IE when included in NL80211_CMD_CONNECT, as following. Driver shall not modify the IEs specified through NL80211_ATTR_IE if NL80211_ATTR_MAC is included. However, if NL80211_ATTR_MAC_HINT is included, these IEs through NL80211_ATTR_IE are specified by the user space based on the best possible BSS selected. Thus, if the driver ends up selecting a different BSS, it can modify these IEs accordingly (e.g. userspace asks the driver to perform PMKSA caching with BSS1 and the driver ends up selecting BSS2 with different PMKSA cache entry. RSNIE has to get updated with the apt PMKID).
