2020-03-29mac80211: fix authentication with iwlwifi/mvmJohannes Berg1-1/+2
The original patch didn't copy the ieee80211_is_data() condition because on most drivers the management frames don't go through this path. However, they do on iwlwifi/mvm, so we do need to keep the condition here.

2020-03-26mac80211: set IEEE80211_TX_CTRL_PORT_CTRL_PROTO for nl80211 TXJohannes Berg1-2/+6
When a frame is transmitted via the nl80211 TX rather than as a normal frame, IEEE80211_TX_CTRL_PORT_CTRL_PROTO wasn't set and this will lead to wrong decisions (rate control etc.) being made about the frame; fix this.

2020-03-26mac80211: mark station unauthorized before key removalJohannes Berg1-1/+6
If a station is still marked as authorized, mark it as no longer so before removing its keys. This allows frames transmitted to it to be rejected, providing additional protection against leaking plain text data during the disconnection flow.

2020-03-26mac80211: Check port authorization in the ieee80211_tx_dequeue() caseJouni Malinen1-1/+18
mac80211 used to check port authorization in the Data frame enqueue case when going through start_xmit(). However, that authorization status may change while the frame is waiting in a queue. Add a similar check in the dequeue case to avoid sending previously accepted frames after authorization change. This provides additional protection against potential leaking of frames after a station has been disconnected and the keys for it are being removed.

2020-03-26mac80211: drop data frames without key on encrypted linksJohannes Berg4-12/+24
If we know that we have an encrypted link (based on having had a key configured for TX in the past) then drop all data frames in the key selection handler if there's no key anymore. This fixes an issue with mac80211 internal TXQs - there we can buffer frames for an encrypted link, but then if the key is no longer there when they're dequeued, the frames are sent without encryption. This happens if a station is disconnected while the frames are still on the TXQ. Detecting that a link should be encrypted based on a first key having been configured for TX is fine as there are no use cases for a connection going from with encryption to no encryption. With extended key IDs, however, there is a case of having a key configured for only decryption, so we can't just trigger this behaviour on a key being configured.

2020-03-20mac80211: driver can remain on channel if not using chan_ctxYan-Hsuan Chuang1-1/+1
Some of the drivers are not using channel context, but let the stack to control/switch channels instead. For such cases, driver can still remain on channel because the mac80211 stack actually supports it. The stack will check if the driver is using chan_ctx and has ops->remain_on_channel been hooked. Otherwise it will start its ROC work to remain on channel. So, even if the driver is not using chan_ctx, the driver is still capable of doing remain on channel.

With multiple VIFS ath10k, and probably others, tries to find the minimum txpower for all vifs and uses that when setting txpower in the firmware. If a second vif is added and starts to scan, it's txpower is not initialized yet and it set to zero. ath10k had a patch to ignore zero values, but then it is impossible to actually set txpower to zero. So, instead initialize the txpower to INT_MIN in mac80211, and let drivers know that means the power has not been set and so should be ignored.

2020-02-07nl80211: add src and dst addr attributes for control port tx/rxMarkus Theil2-2/+4
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.

To support Pre Association Security Negotiation (PASN) while already associated to one AP, allow user space to register to Rx authentication frames, so that the user space logic would be able to receive/handle authentication frames from a different AP as part of PASN. Note that it is expected that user space would intelligently register for Rx authentication frames, i.e., only when PASN is used and configure a match filter only for PASN authentication algorithm, as otherwise the MLME functionality of mac80211 would be broken. Additionally, since some versions of the user space daemons wrongly register to all types of authentication frames (which might result in unexpected behavior) allow such registration if the request is for a specific authentication algorithm number.

In case of HE, the RX NSS is taken from the HE capabilities. If the supported NSS capabilities that are reported by AP for HE mode in the HE Capabilities element are different from the NSS capabilities that are reported by AP for the VHT mode in the VHT Capabilities element, use the lowest supported NSS to not get all the values confused.

2020-02-07mac80211: remove supported channels element in 6 GHz if ECSA supportJohannes Berg1-13/+19
We should not include the supported channels element if we have (advertise) support for extended channel switching. To avoid any interop issues because we always added it in the past, obey this restriction only in the (new) 6 GHz band.

2020-02-07mac80211: check whether HE connection is allowed by the reg domainHaim Dreyfuss1-1/+16
The wireless device might be capable to connect HE as well as the AP. However, the regulatory domain might forbid it.

2020-02-07mac80211: simplify and improve HT/VHT/HE disable codeJohannes Berg2-29/+38
Check early on that a device has support for QoS (at least 4 queues) when it supports HT/VHT/HE, so we don't have to check this while connecting. This lets us clean up the code there: move some of it into channel preparation to clean up a bit more, and then change the logic to only check the "wmm_used" flag. Additionally, disable HE consistently when VHT is disabled.

2020-02-07mac80211: consider more elements in parsing CRCJohannes Berg1-6/+12
We only use the parsing CRC for checking if a beacon changed, and elements with an ID > 63 cannot be represented in the filter. Thus, like we did before with WMM and Cisco vendor elements, just statically add these forgotten items to the CRC: - WLAN_EID_VHT_OPERATION - WLAN_EID_OPMODE_NOTIF I guess that in most cases when VHT/HE operation change, the HT operation also changed, and so the change was picked up, but we did notice that pure operating mode notification changes were ignored.
