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 <quic_tamizhr@quicinc.com> Link: https://lore.kernel.org/r/20220908181034.9936-1-quic_tamizhr@quicinc.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2022-08-29genetlink: start to validate reserved header bytesJakub Kicinski1-0/+1
We had historically not checked that genlmsghdr.reserved is 0 on input which prevents us from using those precious bytes in the future. One use case would be to extend the cmd field, which is currently just 8 bits wide and 256 is not a lot of commands for some core families. To make sure that new families do the right thing by default put the onus of opting out of validation on existing families.

2022-08-08wifi: cfg80211: Fix validating BSS pointers in __cfg80211_connect_resultVeerendranath Jakkam1-3/+5
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 <torvalds@linux-foundation.org> Fixes: efbabc116500 ("cfg80211: Indicate MLO connection info in connect and roam callbacks") Signed-off-by: Veerendranath Jakkam <quic_vjakkam@quicinc.com> [kvalo@kernel.org: add more info to the commit log] Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20220805135259.4126630-1-quic_vjakkam@quicinc.com

2022-07-15wifi: mac80211: support MLO authentication/association with one linkJohannes Berg1-0/+3
It might seem a bit pointless to do a multi-link operation connection with just a single link, but this is already a big change, so for now, limit MLO connections to a single link. Extending that to multiple links will require * work on parsing the multi-link element with STA profile properly, including element fragmentation; * checking the per-link status in the multi-link element * implementing logic to have active/inactive links to let drivers decide which links should be active; * implementing multicast RX deduplication; * and likely more. For now this is still useful since it lets us do multi-link connections for the purposes of testing APIs and the higher layers such as wpa_supplicant.

2022-07-15wifi: nl80211: reject fragmented and non-inheritance elementsJohannes Berg1-0/+25
The underlying mac80211 code cannot deal with fragmented elements for purposes of sorting the elements into the association frame, so reject those inside the link. We might want to reject them inside the assoc frame, but they're used today for FILS, so cannot do that. The non-inheritance element inside the links similarly cannot be handled by mac80211, and outside the links it makes no sense. Reject both since using them could lead to an incorrect implementation.

2022-07-15wifi: nl80211: reject link specific elements on assoc linkJohannes Berg1-0/+7
