2020-04-29mac80211: fix memory overlap due to variable length paramRajkumar Manoharan
As of now HE operation element in bss_conf includes variable length optional field followed by other HE variable. Though the optional field never be used, actually it is referring to next member of the bss_conf structure which is not correct. Fix it by declaring needed HE operation fields within bss_conf itself.

2020-04-24mac80211: handle channel frequency offsetThomas Pedersen
cfg80211_chan_def and ieee80211_channel recently gained a frequency offset component. Handle this where it makes sense (potentially required by S1G channels). For IBSS, TDLS, CSA, and ROC we return -EOPNOTSUPP if a channel with frequency offset is passed, since they may or may not work. Once someone tests and verifies these commands work on thos types of channels, we can remove that error. join_ocb and join_mesh look harmless because they use a simple ieee80211_vif_use_channel(), which is using an already verified channel, so we let those through.

2020-04-24mac80211: Fail association when AP has no legacy ratesIlan Peer
The MLME logic had a workaround that allowed to continue an association with an AP even if the AP did not provide any basic rates in its supported rates in the association response, assuming that the first (non basic) legacy rate could be used as a basic rate. However, this did not consider the case where the AP (which is obviously buggy) did not provide any legacy rate. Fix this by failing the association, as this can result in an unexpected failure in the low level driver and FW, e.g., in rate scale logic etc. Signed-off-by: Ilan Peer <ilan.peer@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com> Link: https://lore.kernel.org/r/iwlwifi.20200326150855.d70a1450d83f.I6e6ce5efda351a8544c0e7bfeee260fe3360d401@changeid Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-04-24cfg80211: change internal management frame registration APIJohannes Berg
Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.

2020-03-26mac80211: drop data frames without key on encrypted linksJohannes Berg
If we know that we have an encrypted link (based on having had a key configured for TX in the past) then drop all data frames in the key selection handler if there's no key anymore. This fixes an issue with mac80211 internal TXQs - there we can buffer frames for an encrypted link, but then if the key is no longer there when they're dequeued, the frames are sent without encryption. This happens if a station is disconnected while the frames are still on the TXQ. Detecting that a link should be encrypted based on a first key having been configured for TX is fine as there are no use cases for a connection going from with encryption to no encryption. With extended key IDs, however, there is a case of having a key configured for only decryption, so we can't just trigger this behaviour on a key being configured.

2020-02-24mac80211: Update BIP to support Beacon framesJouni Malinen
When BIP is used to protect Beacon frames, the Timestamp field is masked to zero. Otherwise, the BIP processing is identical to the way it was already used with group-addressed Robust Management frames.

2020-02-24mac80211: Support BIGTK configuration for Beacon protectionJouni Malinen
Extend mac80211 key configuration to support the new BIGTK with key index values 6 and 7. Support for actually protecting Beacon frames (adding the MME in AP mode and checking it in STA mode) is covered in separate commits.

2020-02-24Revert "nl80211: add src and dst addr attributes for control port tx/rx"Johannes Berg
This reverts commit 8c3ed7aa2b9ef666195b789e9b02e28383243fa8. As Jouni points out, there's really no need for this, since the RSN pre-authentication frames are normal data frames, not port control frames (locally). We can still revert this now since it hasn't actually gone beyond -next.

2020-02-14mac80211: allow setting queue_len for drivers not using wake_tx_queueJohn Crispin
Currently a mac80211 driver can only set the txq_limit when using wake_tx_queue. Not all drivers use wake_tx_queue. This patch adds a new element to wiphy allowing a driver to set a custom tx_queue_len and the code that will apply it in case it is set. The current default is 1000 which is too low for ath11k when doing HE rates.
