2019-03-22iwlwifi: add support for 6-7 GHz channelsShaul Triebitz3-31/+49
Add UHB (ultra high band) channels and use 16 bit variables to fit the new channels. Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-03-22iwlwifi: mvm: be more forgiving if num of channels is too bigShaul Triebitz1-10/+15
If number of channels in the driver is greater than number of scan channels given by firmware TLV, do not fail scan config, but adjust to firmware's number of channels. This is helpful for supporting in driver new channels before it being supported by firmware scan. Signed-off-by: Shaul Triebitz <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2019-03-22iwlwifi: mvm: track changes in beacon count during channel switchSara Sharon2-0/+17
There are some buggy APs that keeps changing the count while forcing us to block TX. This eventually results in queue hang, assert, and disconnection. Detect such APs and disconnect gracefully in advance. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-03-22iwlwifi: mvm: disconnect in case of bad channel switch parametersSara Sharon4-77/+107
In case we receive channel switch announcement with immediate quiet and unknown switching time, we will switch when FW identifies AP left channel. However, if AP remains on channel, we will eventually get TX queue hang. Init a work to disconnect if switch doesn't occur within 1500 milliseconds. Do it also for a too long channel switch.

2019-03-22iwlwifi: mvm: track CSA beaconsSara Sharon2-2/+30

2019-03-22iwlwifi: use sync nmi in case of init flow failureShahar S Matityahu3-31/+3
In case of alive interrupt timeout or any failure in the init flow the driver generates FW nmi. The driver assumes that the nmi will generate SW interrupt. This assumption does not hold and leads to faulty behavior in the recovery flow. Solve this by using sync nmi, this way, even if the driver does not receive SW interrupt, it still starts the recovery flow. Also remove the wait queue from iwl_fwrt_stop_device since the driver is handling the SW interrupt synchronously.

2019-03-22iwlwifi: dbg_ini: fix bad dump size calculationShahar S Matityahu1-3/+3
The driver initiates the size value with the size of the struct and then adds the size of the data and checks if the size is zero so size can not be equal to zero. Solve this by getting the data size, check that it is not equal to zero and only then add the struct size.

2019-03-22iwlwifi: dbg_ini: in case of region dump failure set memory to 0Shahar S Matityahu1-0/+2
In case the driver fails to dump a memory region, and this is the last region, then partial region would be extracted. Solve this by setting the data to zero in case of failure. This will cause dump to be a list of consecutive successful memory regions and trailing zeros with no partial memories extracted.

2019-03-22iwlwifi: mvm: fix TX crypto on 22560+ devicesJohannes Berg4-94/+19
In the old days, we could transmit with HW crypto with an arbitrary key by filling it into TX_CMD. This was broken first with the advent of CCMP/GCMP-256 keys which don't fit there. This was broken *again* with the newer TX_CMD format on 22560+, where we simply cannot pass key material anymore. However, we forgot to update all the cases when we get a key from mac80211 and don't program it into the hardware but still return 0 for HW crypto on TX. In AP mode with WEP, we tried to fix this by programming the keys separately for each station later, but this ultimately turns out to be buggy, for example now it leaks memory when we have more than one WEP key. Fix this by simply using only SW crypto for WEP in newer devices by returning -EOPNOTSUPP instead of trying to program WEP keys later.

2019-03-20net: remove 'fallback' argument from dev->ndo_select_queue()Paolo Abeni1-2/+1
After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit.

2019-03-19mt76x02: do not enable RTS/CTS by defaultStanislaw Gruszka3-3/+2
My commit 26a7b5473191 ("mt76x02: set protection according to ht operation element") enabled by default RTS/CTS protection for OFDM and CCK traffic, because MT_TX_RTS_CFG_THRESH is configured to non 0xffff by initvals and .set_rts_threshold callback is not called by mac80211 on initialization, only on user request or during ieee80211_reconfig() (suspend/resuem or restart_hw). Enabling RTS/CTS cause some problems when sending probe request frames by hcxdumptool penetration tool, but I expect it can cause other issues on different scenarios. Restore previous setting of RTS/CTS being disabled by default for OFDM/CCK by changing MT_TX_RTS_CFG_THRESH initvals to 0xffff.

Full tx blocking (as opposed to CCA blocking) should only happen if there is a continuous non-802.11 signal above the energy detect threshold. Unfortunately the ED/CCA counter can't detect that, as it also counts 802.11 signals as busy. Similar to the vendor code, implement a learning mode that waits until the AGC gain has already been adjusted to the lowest value (due to false CCA events), and the number of false CCA events still remains high, and the blocking threshold is exceeded for more than 5 seconds.

For Rx packets cid from rx descriptor is limited to 3 bits (0..7), to find the real cid, compare transmitter address with the stored stations mac address in the driver sta array.
