wifi: cfg80211: fix MCS divisor value

2022-09-27T08:26:55Z

The Bitrate for HE/EHT MCS6 is calculated wrongly due to the incorrect MCS divisor value for mcs6. Fix it with the proper value. previous mcs_divisor value = (11769/6144) = 1.915527 fixed mcs_divisor value = (11377/6144) = 1.851725 Fixes: 9c97c88d2f4b ("cfg80211: Add support to calculate and report 4096-QAM HE rates") Signed-off-by: Tamizh Chelvam Raja Link: https://lore.kernel.org/r/20220908181034.9936-1-quic_tamizhr@quicinc.com Signed-off-by: Johannes Berg

wifi: use struct_group to copy addresses

2022-09-03T14:40:06Z

We sometimes copy all the addresses from the 802.11 header for the AAD, which may cause complaints from fortify checks. Use struct_group() to avoid the compiler warnings/errors. Change-Id: Ic3ea389105e7813b22095b295079eecdabde5045 Signed-off-by: Johannes Berg

wifi: cfg80211: debugfs: fix return type in ht40allow_map_read()

2022-08-25T08:04:46Z

The return type is supposed to be ssize_t, which is signed long, but "r" was declared as unsigned int. This means that on 64 bit systems we return positive values instead of negative error codes.

wifi: cfg80211: Fix validating BSS pointers in __cfg80211_connect_result

2022-08-08T08:09:52Z

Driver's SME is allowed to fill either BSSID or BSS pointers in struct cfg80211_connect_resp_params when indicating connect response but a check in __cfg80211_connect_result() is giving unnecessary warning when driver's SME fills only BSSID pointer and not BSS pointer in struct cfg80211_connect_resp_params. In case of mac80211 with auth/assoc path, it is always expected to fill BSS pointers in struct cfg80211_connect_resp_params when calling __cfg80211_connect_result() since cfg80211 must have hold BSS pointers in cfg80211_mlme_assoc(). So, skip the check for the drivers which support cfg80211 connect callback, for example with brcmfmac is one such driver which had the warning: WARNING: CPU: 5 PID: 514 at net/wireless/sme.c:786 __cfg80211_connect_result+0x2fc/0x5c0 [cfg80211] Reported-by: Linus Torvalds Fixes: efbabc116500 ("cfg80211: Indicate MLO connection info in connect and roam callbacks") Signed-off-by: Veerendranath Jakkam [kvalo@kernel.org: add more info to the commit log] Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220805135259.4126630-1-quic_vjakkam@quicinc.com

wifi: nl80211: add MLO link ID to the NL80211_CMD_FRAME TX API

2022-07-22T12:28:33Z

Allow optionally specifying the link ID to transmit on, which can be done instead of the link frequency, on an MLD addressed frame. Both can also be omitted in which case the frame must be MLD addressed and link selection (and address translation) will be done on lower layers. Signed-off-by: Johannes Berg

wifi: cfg80211: report link ID in NL80211_CMD_FRAME

If given by the underlying driver, report the link ID for MLO in NL80211_CMD_FRAME. Signed-off-by: Johannes Berg

wifi: cfg80211: add hardware timestamps to frame RX info

2022-07-22T12:28:27Z

Add hardware timestamps to management frame RX info. This shall be used by drivers that support hardware timestamping for Timing measurement and Fine timing measurement action frames RX. Signed-off-by: Avraham Stern Signed-off-by: Johannes Berg

wifi: cfg80211/nl80211: move rx management data into a struct

2022-07-22T12:28:26Z

The functions for reporting rx management take many arguments. Collect all the arguments into a struct, which also make it easier to add more arguments if needed. Signed-off-by: Avraham Stern Signed-off-by: Johannes Berg

wifi: cfg80211: add a function for reporting TX status with hardware timestamps

wifi: nl80211: require MLD address on link STA add/modify

2022-07-22T12:28:13Z

We always need the MLD address and link ID to add or modify the link STA, so require it in the API. Fixes: 577e5b8c3924 ("wifi: cfg80211: add API to add/modify/remove a link station") Signed-off-by: Johannes Berg
