2020-02-07nl80211: add src and dst addr attributes for control port tx/rxMarkus Theil
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 Jakkam
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.

In case a radar event of CAC_FINISHED or RADAR_DETECTED happens during another phy is during CAC we might need to cancel that CAC. If we got a radar in a channel that another phy is now doing CAC on then the CAC should be canceled there. If, for example, 2 phys doing CAC on the same channels, or on comptable channels, once on of them will finish his CAC the other might need to cancel his CAC, since it is no longer relevant. To fix that the commit adds an callback and implement it in mac80211 to end CAC.

2019-11-22mac80211: Implement Airtime-based Queue Limit (AQL)Kan Yan
In order for the Fq_CoDel algorithm integrated in mac80211 layer to operate effectively to control excessive queueing latency, the CoDel algorithm requires an accurate measure of how long packets stays in the queue, AKA sojourn time. The sojourn time measured at the mac80211 layer doesn't include queueing latency in the lower layer (firmware/hardware) and CoDel expects lower layer to have a short queue. However, most 802.11ac chipsets offload tasks such TX aggregation to firmware or hardware, thus have a deep lower layer queue. Without a mechanism to control the lower layer queue size, packets only stay in mac80211 layer transiently before being sent to firmware queue. As a result, the sojourn time measured by CoDel in the mac80211 layer is almost always lower than the CoDel latency target, hence CoDel does little to control the latency, even when the lower layer queue causes excessive latency. The Byte Queue Limits (BQL) mechanism is commonly used to address the similar issue with wired network interface. However, this method cannot be applied directly to the wireless network interface. "Bytes" is not a suitable measure of queue depth in the wireless network, as the data rate can vary dramatically from station to station in the same network, from a few Mbps to over Gbps. This patch implements an Airtime-based Queue Limit (AQL) to make CoDel work effectively with wireless drivers that utilized firmware/hardware offloading. AQL allows each txq to release just enough packets to the lower layer to form 1-2 large aggregations to keep hardware fully utilized and retains the rest of the frames in mac80211 layer to be controlled by the CoDel algorithm.

2019-11-08cfg80211: VLAN offload support for set_key and set_sta_vlanGurumoorthi Gnanasambandhan
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.

2019-10-07mac80211: fix scan when operating on DFS channels in ETSI domainsAaron Komisar
In non-ETSI regulatory domains scan is blocked when operating channel is a DFS channel. For ETSI, however, once DFS channel is marked as available after the CAC, this channel will remain available (for some time) even after leaving this channel. Therefore a scan can be done without any impact on the availability of the DFS channel as no new CAC is required after the scan. Enable scan in mac80211 in these cases.

2019-08-21nl80211: Add support for EDMG channelsAlexei Avshalom Lazar
802.11ay specification defines Enhanced Directional Multi-Gigabit (EDMG) STA and AP which allow channel bonding of 2 channels and more. Introduce new NL attributes that are needed for enabling and configuring EDMG support. Two new attributes are used by kernel to publish driver's EDMG capabilities to the userspace: NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16 GHz channel(s) that are supported by the driver. When this attribute is not set it means driver does not support EDMG. NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth configurations supported by the driver. Additional two new attributes are used by the userspace for connect command and for AP configuration: NL80211_ATTR_WIPHY_EDMG_CHANNELS NL80211_ATTR_WIPHY_EDMG_BW_CONFIG New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver and used for bitrate calculation that will take into account EDMG according to the 802.11ay specification.

2019-07-26{nl,mac}80211: fix interface combinations on crypto controlled devicesManikanta Pubbisetty
Commit 33d915d9e8ce ("{nl,mac}80211: allow 4addr AP operation on crypto controlled devices") has introduced a change which allows 4addr operation on crypto controlled devices (ex: ath10k). This change has inadvertently impacted the interface combinations logic on such devices. General rule is that software interfaces like AP/VLAN should not be listed under supported interface combinations and should not be considered during validation of these combinations; because of the aforementioned change, AP/VLAN interfaces(if present) will be checked against interfaces supported by the device and blocks valid interface combinations. Consider a case where an AP and AP/VLAN are up and running; when a second AP device is brought up on the same physical device, this AP will be checked against the AP/VLAN interface (which will not be part of supported interface combinations of the device) and blocks second AP to come up. Add a new API cfg80211_iftype_allowed() to fix the problem, this API works for all devices with/without SW crypto control.

2019-06-14nl80211: send event when CMD_FRAME duration expiresJames Prestwood
cfg80211_remain_on_channel_expired is used to notify userspace when the remain on channel duration expired by sending an event. There is no such equivalent to CMD_FRAME, where if offchannel and a duration is provided, the card will go offchannel for that duration. Currently there is no way for userspace to tell when that duration expired apart from setting an independent timeout. This timeout is quite erroneous as the kernel may not immediately send out the frame because of scheduling or work queue delays. In testing, it was found this timeout had to be quite large to accomidate any potential delays. A better solution is to have the kernel send an event when this duration has expired. There is already NL80211_CMD_FRAME_WAIT_CANCEL which can be used to cancel a NL80211_CMD_FRAME offchannel. Using this command matches perfectly to how NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL works, where its both used to cancel and notify if the duration has expired.

2019-05-28cfg80211: Handle bss expiry during connectionChaitanya Tata
If the BSS is expired during connection, the connect result will trigger a kernel warning. Ideally cfg80211 should hold the BSS before the connection is attempted, but as the BSSID is not known in case of auth/assoc MLME offload (connect op) it doesn't. For those drivers without the connect op cfg80211 holds down the reference so it wil not be removed from list. Fix this by removing the warning and silently adding the BSS back to the bss list which is return by the driver (with proper BSSID set) or in case the BSS is already added use that. The requirements for drivers are documented in the API's.

2019-05-24{nl,mac}80211: allow 4addr AP operation on crypto controlled devicesManikanta Pubbisetty
As per the current design, in the case of sw crypto controlled devices, it is the device which advertises the support for AP/VLAN iftype based on it's ability to tranmsit packets encrypted in software (In VLAN functionality, group traffic generated for a specific VLAN group is always encrypted in software). Commit db3bdcb9c3ff ("mac80211: allow AP_VLAN operation on crypto controlled devices") has introduced this change. Since 4addr AP operation also uses AP/VLAN iftype, this conditional way of advertising AP/VLAN support has broken 4addr AP mode operation on crypto controlled devices which do not support VLAN functionality. In the case of ath10k driver, not all firmwares have support for VLAN functionality but all can support 4addr AP operation. Because AP/VLAN support is not advertised for these devices, 4addr AP operations are also blocked. Fix this by allowing 4addr operation on devices which do not support AP/VLAN iftype but can support 4addr AP operation (decision is based on the wiphy flag WIPHY_FLAG_4ADDR_AP).

Adding support to allow mesh HWMP to measure link metrics on unexercised direct mesh path by sending some data frames to other mesh points which are not currently selected as a primary traffic path but 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.
