git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next Kalle Valo says: ==================== wireless-drivers-next patches for 5.1 Most likely the last set of patches for 5.1. WPA3 support to ath10k and qtnfmac. FTM support to iwlwifi and ath10k. And of course other new features and bugfixes. wireless-drivers was merged due to dependency in mt76. Major changes: iwlwifi * HE radiotap * FTM (Fine Timing Measurement) initiator and responder implementation * bump supported firmware API to 46 * VHT extended NSS support * new PCI IDs for 9260 and 22000 series ath10k * change QMI interface to support the new (and backwards incompatible) interface from HL3.1 and used in recent HL2.0 branch firmware releases * support WPA3 with WCN3990 * support for mac80211 airtime fairness based on transmit rate estimation, the firmware needs to support WMI_SERVICE_PEER_STATS to enable this * report transmit airtime to mac80211 with firmwares having WMI_SERVICE_REPORT_AIRTIME feature, this to have more accurate airtime fairness based on real transmit time (instead of just estimated from transmit rate) * support Fine Timing Measurement (FTM) responder role * add dynamic VLAN support with firmware having WMI_SERVICE_PER_PACKET_SW_ENCRYPT * switch to use SPDX license identifiers ath * add new country codes for US brcmfmac * support monitor frames with the hardware/ucode header qtnfmac * enable WPA3 SAE and OWE support mt76 * beacon support for USB devices (mesh+ad-hoc only) rtlwifi * convert to use SPDX license identifiers libertas_tf * get the MAC address before registering the device ==================== Signed-off-by: David S.

2019-02-20iwlwifi: nvm-parse: advertise IEEE80211_VHT_EXT_NSS_BW_CAPABLE in VHTJohannes Berg1-2/+5
We support this, so we should advertise it. In fact, if we don't, mac80211 will do it for us (as we advertise SUPPORTS_VHT_EXT_NSS_BW to it), but that requires a memory reallocation which is wasteful: ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag Set the flag here to avoid that.

2019-02-20iwlwifi: nvm-parse: use struct_size() in kzalloc()Gustavo A. R. Silva1-11/+7
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; void *entry[]; }; instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); This code was detected with the help of Coccinelle.

2019-02-14iwlwifi: do not fail on large amount of channelsShaul Triebitz1-3/+3
Until supporting UHB (ultra high band) channels for devices AX210, do not fail if number of channels reported by firmware is greater than NL80211_MAX_SUPP_REG_RULES.

2018-10-06iwlwifi: nvm: get num of hw addresses from firmwareNaftali Goldstein1-1/+9
With NICs that don't read the NVM directly and instead rely on getting the relevant data from the firmware, the number of reserved MAC addresses was not added to the API. This caused the driver to assume there is only one address which results in all interfaces getting the same address. Update the API to fix this. While at it, fix-up the comments with firmware api names to actually match what we have in the firmware.

Make wmm_rule be part of the reg_rule structure. This simplifies the code a lot at the cost of having bigger memory usage. However in most cases we have only few reg_rule's and when we do have many like in iwlwifi we do not save memory as it allocates a separate wmm_rule for each channel anyway. This also fixes a bug reported in various places where somewhere the pointers were corrupted and we ended up doing a null-dereference.

There are many places where the same process of invoking a method from ACPI is used, causing a lot of duplicate code. To improve this, introduce a new function to get an ACPI object by invoking an ACPI method that can be reused.

2017-10-06iwlwifi: nvm-parse: unify channel flags printingJohannes Berg1-59/+39
The current channel flags printing is very strange and messy, in LAR we sometimes print the channel number and sometimes the frequency, in both we print a calculated value (whether ad-hoc is supported or not) etc. Unify all this to * print the channel number, not the frequency * remove the band print (2.4/5.2 GHz, it's obvious) * remove the calculated Ad-Hoc print Doing all of this also gets the length of the string to a max of 101 characters, which is below the max of 110 for tracing, and thus avoids the warning that came up on certain channels with certain flag combinations.

2017-08-01iwlwifi: split the regulatory rules when the bandwidth flags require itEmmanuel Grumbach1-8/+11
When we create a regulatory domain out of an MCC notification, we need to make sure that all the channels in the rule have the exact same properties. The current code mixes channel 36 and 40 although 36 can be a control channel with HT40+ (36, 40) whereas 40 can't be a control channel with HT40+ since (40, 44) is invalid. Because of that, cfg80211 would allow to connect in 40MHz to APs that are configured to channel 40 HT40+ and that made our firmware assert. Fix this by checking the bandwidth flags before taking the decision if the rule should be split. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=195299 partly.
