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.

The wireless device might be capable to connect HE as well as the AP. However, the regulatory domain might forbid it. Check whether the regulatory domain allows HE connection when considering if HE IE should be added. Also, add it when setting our peer capability. Signed-off-by:

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:

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>

If Rx flow control has been enabled (via autoneg or forced), packets should not be dropped due to Rx descriptor ring exhaustion. Instead pause frames should be used to apply back pressure. This only applies if VFs are not in use. Move SRRCTL setup to its own function for easy reuse and only set drop enable bit if Rx flow control is not enabled. Since v1: always enable dropping of packets if VFs in use. Signed-off-by:

Revert "net/sched: cls_u32: fix refcount leak in the error path of u32_change()", and fix the u32 refcount leak in a more generic way that preserves the semantic of rule dumping. On tc filters that don't support lockless insertion/removal, there is no need to guard against concurrent insertion when a removal is in progress. Therefore, for most of them we can avoid a full walk() when deleting, and just decrease the refcount, like it was done on older Linux kernels. This fixes situations where walk() was wrongly detecting a non-empty filter, like it happened with cls_u32 in the error path of change(), thus leading to failures in the following tdc selftests: 6aa7: (filter, u32) Add/Replace u32 with source match and invalid indev 6658: (filter, u32) Add/Replace u32 with custom hash table and invalid handle 74c2: (filter, u32) Add/Replace u32 filter with invalid hash table id On cls_flower, and on (future) lockless filters, this check is necessary: move all the check_empty() logic in a callback so that each filter can have its own implementation. For cls_flower, it's sufficient to check if no IDRs have been allocated. This reverts commit 275c44aa. Changes since v1: - document the need for delete_empty() when TCF_PROTO_OPS_DOIT_UNLOCKED is used, thanks to Vlad Buslov - implement delete_empty() without doing fl_walk(), thanks to Vlad Buslov - squash revert and new fix in a single patch, to be nice with bisect tests that run tdc on u32 filter, thanks to Dave Miller Fixes: 275c44aa ("net/sched: cls_u32: fix refcount leak in the error path of u32_change()") Fixes: 6676d5e4 ("net: sched: set dedicated tcf_walker flag when tp is empty") Suggested-by:
