2021-02-12mac80211: add STBC encoding to ieee80211_parse_tx_radiotapPhilipp Borgers
This patch adds support for STBC encoding to the radiotap tx parse function. Prior to this change adding the STBC flag to the radiotap header did not encode frames with STBC.

2021-02-12mac80211: enable QoS support for nl80211 ctrl portMarkus Theil
This patch unifies sending control port frames over nl80211 and AF_PACKET sockets a little more. Before this patch, EAPOL frames got QoS prioritization only when using AF_PACKET sockets. __ieee80211_select_queue only selects a QoS-enabled queue for control port frames, when the control port protocol is set correctly on the skb. For the AF_PACKET path this works, but the nl80211 path used ETH_P_802_3. Another check for injected frames in wme.c then prevented the QoS TID to be copied in the frame. In order to fix this, get rid of the frame injection marking for nl80211 ctrl port and set the correct ethernet protocol. Please note: An erlier version of this path tried to prevent frame aggregation for control port frames in order to speed up the initial connection setup a little. This seemed to cause issues on my older Intel dvm-based hardware, and was therefore removed again. Future commits which try to reintroduce this have to check carefully how hw behaves with aggregated and non-aggregated traffic for the same TID.

2020-11-06mac80211: assure that certain drivers adhere to DONT_REORDER flagMathy Vanhoef
Some drivers use skb->priority to determine on which queue to send a frame. An example is mt76x2u (this was tested on an AWUS036ACM). This means these drivers currently do not adhere to the DONT_REORDER flag. To fix this, we do not set skb->priority based on the QoS TID of injected frames when the DONT_REORDER flag is set.

2020-11-06mac80211: don't overwrite QoS TID of injected framesMathy Vanhoef
Currently ieee80211_set_qos_hdr sets the QoS TID of all frames based on the value assigned to skb->priority. This means it will also overwrite the QoS TID of injected frames. The commit 753ffad3d624 ("mac80211: fix TID field in monitor mode transmit") prevented injected frames from being modified because of this by setting skb->priority to the TID of the injected frame, which assured the QoS TID will not be changed to a different value. Unfortunately, this workaround complicates the handling of injected frames because we can't set skb->priority without affecting the TID value in the QoS field of injected frames. To avoid this, and to simplify the next patch, detect if a frame is injected in ieee80211_set_qos_hdr and if so do not change its QoS field.

2020-10-30mac80211: fix use of skb payload instead of headerJohannes Berg
When ieee80211_skb_resize() is called from ieee80211_build_hdr() the skb has no 802.11 header yet, in fact it consist only of the payload as the ethernet frame is removed. As such, we're using the payload data for ieee80211_is_mgmt(), which is of course completely wrong. This didn't really hurt us because these are always data frames, so we could only have added more tailroom than we needed if we determined it was a management frame and sdata->crypto_tx_tailroom_needed_cnt was false. However, syzbot found that of course there need not be any payload, so we're using at best uninitialized memory for the check. Fix this to pass explicitly the kind of frame that we have instead of checking there, by replacing the "bool may_encrypt" argument with an argument that can carry the three possible states - it's not going to be encrypted, it's a management frame, or it's a data frame (and then we check sdata->crypto_tx_tailroom_needed_cnt).

2020-10-30mac80211: fix regression where EAPOL frames were sent in plaintextMathy Vanhoef
When sending EAPOL frames via NL80211 they are treated as injected frames in mac80211. Due to commit 1df2bdba528b ("mac80211: never drop injected frames even if normally not allowed") these injected frames were not assigned a sta context in the function ieee80211_tx_dequeue, causing certain wireless network cards to always send EAPOL frames in plaintext. This may cause compatibility issues with some clients or APs, which for instance can cause the group key handshake to fail and in turn would cause the station to get disconnected. This commit fixes this regression by assigning a sta context in ieee80211_tx_dequeue to injected frames as well. Note that sending EAPOL frames in plaintext is not a security issue since they contain their own encryption and authentication protection.

2020-09-18mac80211: rework tx encapsulation offload APIFelix Fietkau
The current API (which lets the driver turn on/off per vif directly) has a number of limitations: - it does not deal with AP_VLAN - conditions for enabling (no tkip, no monitor) are only checked at add_interface time - no way to indicate 4-addr support In order to address this, store offload flags in struct ieee80211_vif (easy to extend for decap offload later). mac80211 initially sets the enable flag, but gives the driver a chance to modify it before its settings are applied. In addition to the .add_interface op, a .update_vif_offload op is introduced, which can be used for runtime changes. If a driver can't disable encap offload at runtime, or if it has some extra limitations, it can simply override the flags within those ops. Support for encap offload with 4-address mode interfaces can be enabled by setting a flag from .add_interface or .update_vif_offload.

AQL does not take into account that most HT/VHT/HE traffic is A-MPDU aggregated. Because of that, the per-packet airtime overhead is vastly overestimated. Improve it by assuming an average aggregation length of 16 for non-legacy traffic if not using the VO AC queue. This should improve performance with high data rates, especially with multiple stations Signed-off-by: Felix Fietkau <nbd@nbd.name> Link: https://lore.kernel.org/r/20200724182816.18678-1-nbd@nbd.name Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2020-07-30mac80211: Fix bug in Tx ack status reporting in 802.3 xmit pathVasanthakumar Thiagarajan
Allocated ack_frame id from local->ack_status_frames is not really stored in the tx_info for 802.3 Tx path. Due to this, tx ack status is not reported and ack_frame id is not freed for the buffers requiring tx ack status. Also move the memset to 0 of tx_info before IEEE80211_TX_CTL_REQ_TX_STATUS flag assignment.

2020-06-25mac80211: skip mpath lookup also for control port txMarkus Theil
When using 802.1X over mesh networks, at first an ordinary mesh peering is established, then the 802.1X EAPOL dialog happens, afterwards an authenticated mesh peering exchange (AMPE) happens, finally the peering is complete and we can set the STA authorized flag. As 802.1X is an intermediate step here and key material is not yet exchanged for stations we have to skip mesh path lookup for these EAPOL frames. Otherwise the already configure mesh group encryption key would be used to send a mesh path request which no one can decipher, because we didn't already establish key material on both peers, like with SAE and directly using AMPE.

Maintain the connection AID only in sdata->vif.bss_conf.aid, not also in sdata->u.mgd.aid. Keep setting that where we set ifmgd->aid before, which has the side effect of exposing the AID to the driver before the station entry (AP) is marked associated, in case it needs it then.
