mac80211: allow rx of mesh eapol frames with default rx key

2020-06-25T10:55:45+00:00

Without this patch, eapol frames cannot be received in mesh mode, when 802.1X should be used. Initially only a MGTK is defined, which is found and set as rx->key, when there are no other keys set. ieee80211_drop_unencrypted would then drop these eapol frames, as they are data frames without encryption and there exists some rx->key. Fix this by differentiating between mesh eapol frames and other data frames with existing rx->key. Allow mesh mesh eapol frames only if they are for our vif address. With this patch in-place, ieee80211_rx_h_mesh_fwding continues after the ieee80211_drop_unencrypted check and notices, that these eapol frames have to be delivered locally, as they should.

mac80211: fix HT-Control field reception for management frames

2020-05-27T08:03:27+00:00

If we receive management frames with an HT-Control field, we cannot parse them properly, as we assume a fixed length management header. Since we don't even need the HTC field (for these frames, or really at all), just remove it at the beginning of RX.

mac80211: allow SA-QUERY processing in userspace

2020-05-27T08:02:04+00:00

As discussed with Mathy almost two years ago in http://lore.kernel.org/r/20180806224857.14853-1-Mathy.Vanhoef@cs.kuleuven.be we should let userspace process SA-QUERY frames if it wants to, so that it can handle OCV (operating channel validation) which mac80211 doesn't know how to. Evidently I had been expecting Mathy to (re)send such a patch, but he never did, perhaps expecting me to do it after our discussion. In any case, this came up now with OCV getting more attention, so move the code around as discussed there to let userspace handle it, and do it properly.

cfg80211: add KHz variants of frame RX API

2020-05-27T08:02:02+00:00

Drivers may wish to report the RX frequency in units of KHz. Provide cfg80211_rx_mgmt_khz() and wrap it with cfg80211_rx_mgmt() so exisiting drivers which can't report KHz anyway don't need to change. Add a similar wrapper for cfg80211_report_obss_beacon() so the frequency units stay somewhat consistent. This doesn't actually change the nl80211 API yet.

mac80211: add freq_offset to RX status

2020-04-24T10:33:43+00:00

RX status needs a KHz component, so add freq_offset. We can reduce the bits for the frequency since 60 GHz isn't supported. Signed-off-by: Thomas Pedersen Link: https://lore.kernel.org/r/20200402011810.22947-5-thomas@adapt-ip.com [fix commit message] Signed-off-by: Johannes Berg

mac80211: rx: avoid RCU list traversal under mutex

2020-02-24T09:42:38+00:00

local->sta_mtx is held in __ieee80211_check_fast_rx_iface(). No need to use list_for_each_entry_rcu() as it also requires a cond argument to avoid false lockdep warnings when not used in RCU read-side section (with CONFIG_PROVE_RCU_LIST). Therefore use list_for_each_entry(); Signed-off-by: Madhuparna Bhowmik Link: https://lore.kernel.org/r/20200223143302.15390-1-madhuparnabhowmik10@gmail.com Signed-off-by: Johannes Berg
