This is now a trivial patch, but for seeing the actual changes I (Johannes) split it out from the original. Signed-off-by:

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:

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.

According to IEEE802.11 specifications the SM power save field in the HT capability IE and the HE extended capability IE is valid only in (re)association frames and should be ignored otherwise. Remove code paths that handled this also for non AP modes. Signed-off-by:

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.

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. Signed-off-by:

Commit ab4dfa20 ("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.

The 802.11 encapsulation returned early when setting up the keys in case offloading was enabled. This causes ieee802.11w to not work anymore. Fix this by moving the check for offloading into the switch/case construct and allowing CCMP/GCMP keys. With this patch applied ieee80211w works again when enabling offloading.

commit 08a5bdde ("mac80211: consider QoS Null frames for STA_NULLFUNC_ACKED") Fixed a bug where we failed to take into account a nullfunc frame can be either non-QoS or QoS. It turns out there is at least one more bug in ieee80211_sta_tx_notify(), introduced in commit 7b6ddeaf ("mac80211: use QoS NDP for AP probing"), where we forgot to check for the QoS variant and so assumed the QoS nullfunc frame never went out Fix this by adding a helper ieee80211_is_any_nullfunc() which consolidates the check for non-QoS and QoS nullfunc frames. Replace existing compound conditionals and add a couple more missing checks for QoS variant. Signed-off-by:

Advertise the correct flags to mac80211 to indicate PS trigger frames and frame buffering should be handled by mac80211. This means mac80211_hwsim will now also have to release buffered multicast frames after a (DTIM) beacon.

It is now possible to propagate BSS color settings into the subsystem. Lets make mac80211 also handle them so that we can send them further down the stack into the drivers. We drop the old bss_color field and change iwlwifi to use the new he_bss_color struct. Signed-off-by:

This is too low, at least ETSI regulatory domain would allow 36 dBm on 5 GHz in (some? most?) cases. But there's no reason hwsim should have a limit at all, so remove it.

Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2019-12-31 This series contains updates to e1000e, igb and igc only. Robert Beckett provide an igb change to assist in keeping packets from being dropped due to receive descriptor ring being full when receive flow control is enabled. Create a separate function to setup SRRCTL to ease in reuse and ensure that setting of the drop enable bit only if receive flow control is not enabled. Sasha adds support for scatter gather support in igc. Improve the direct memory address mapping flow by optimizing/simplifying and more clear. Update igc to use pci_release_mem_regions() instead of pci_release_selected_regions(). Clean up function header comments to align with the actual code. Adds support for 64 bit DMA access, to help handle socket buffer fragments in high memory. Adds legacy power management support in igc by implementing suspend, resume, runtime_suspend/resume, and runtime_idle callbacks. Clean up references to Serdes interface in igc since that interface is not supported for i225 devices. Alex replaces the pr_info calls with netdev_info in all cases related to netdev link state, as suggested by Joe Perches. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>
