2019-02-14iwlwifi: mvm: stop static queues correctlyAvraham Stern
AP interfaces still use some static TX queues (for probes, broadcast and multicast frames). These queues were not stopped correctly when the transport layer indicated the queue should be stopped. As a result, when flushing the queues, new frames from the overflow queue were tx'd, so the queues still had frames after flushing. This ended up in an assert since trying to remove a station with non-empty queues. Fix it by stopping the static queues correctly when required.

2019-02-14iwlwifi: mvm: Do not return an error value on HW restartIlan Peer
When HW restart is requested but not started yet, commands would not be sent to the FW, and some function calls would return an error. In case of iwl_mvm_mac_sta_state() returning an error value when a station is removed can lead to an unneeded warning in __sta_info_destroy_part2().

2019-02-14iwlwifi: mvm: Don't warn on command failure during restartIlan Peer
When HW restart is requested but not started yet, commands would not be sent to the FW, and some function calls return an error. Such cases can trigger unneeded warning messages, e.g., in iwl_mvm_mac_sta_state() and iwl_mvm_bss_info_changed_station().

In HE-TB PPDUs (labeled HE-TRIG in radiotap), we were overwriting the data4.spatial_reuse_1 field with the spatial reuse data that the firmware gives us for SU/MU PPDUs.

2019-02-14iwlwifi: mvm: add support for new FTM fw APIAvraham Stern
The FTM new API uses API TLV bit 15. The driver mistakenly uses this bit for beacon filter API, although no TLV was assigned for the beacon filter API. For now, make beacon filter use bit 16 instead (not set by the fw anyway). Once a TLV is assigned to the beacon filter API it should be updated.

2019-02-14iwlwifi: mvm: add support for 32kHz external clock indicationHaim Dreyfuss
In low power modes, the chip clock source for platform integrated devices is 32kHz. It is generated internally and supplied by a crystal oscillator. However using a 32kHz sourced from crystal oscillator has high power penalty. There is an option to get an external 32kHz clock from the platform. Past experience shows that the reliability is platform dependent, i.e. on some platforms it works good and on other it doesn’t. Working from external clock will save 0.5 mW in sleep state, from overall 1.8mW that we have today, i.e. almost 30%. Each OEM can enable or disable the use of the external 32kHz clock by setting a BIOS configuration. In case the OEM configured to use 32kHz external clock the driver will pass this indication to the FW.

2019-02-14iwlwifi: mvm: Fix possible NULL pointer dereferenceAvraham Stern
iwl_mvm_te_clear_data() is called for cleanup in case sending the HOT_SPOT_CMD failed. However, in case sending the command caused a fw error and restart (e.g. if the command is not supported) then the te_data pointer may no longer be valid, which leads to a NULL pointer dereference.

2019-02-14iwlwifi: add FW recovery flowMordechay Goodstein
Add new API and TLV for the ability to send commands in the beginning and end of reset flow. The full flow of recovery is: 1. While loading FW, get address (from the TLV) of target buffer to read in case of reset 2. If an error/assert happens read the address data from step 1. 3. Reset the HW and load the FW. 4. Send the data read in step 2. 5. Add station keys 6. Send notification to FW that reset flow is done.

2019-02-04iwlwifi: mvm: fix AP mode in WEPEmmanuel Grumbach
Recently we started to send the WEP keys to the firmware so that we could use hardware Tx encryption also on newer devices that require the keys to be installed in the firmware for encryption (as opposed to older devices that can get the key in the Tx command for each Tx). When we implemented that, we forgot to remove the key when we remove a station leading to a situation where a station that connects and disconnects a lot of times exhausts the key database inside the firmware. A fix was made for that, but we always removed the same key: mvmvif->ap_wep_key which means that we removed the same key entry in the firmware. This can make sense since in WEP, the key is the same for all the stations, but the internal implementation of iwl_mvm_set_sta_key and iwl_mvm_remove_sta_key assumes that each station uses a different key in the firmware's key database. So now we got to the situation where we have a single ieee80211_key_conf instance that means, a single ieee80211_key_conf.hw_key_idx index for several stations and hence for several keys. ieee80211_key_conf.hw_key_idx is set to 0 when the first station associates, and then it is overwritten to 1 when the second station associates which is a buggy of course. This led to the following message upon the removal of the second station: iwlwifi 0000:00:03.0: offset 1 not used in fw key table. WARNING: CPU: 2 PID: 27883 at net/mac80211/sta_info.c:1122 __sta_info_destroy_part2+0x16b/0x180 [mac80211] RIP: 0010:__sta_info_destroy_part2+0x16b/0x180 [mac80211] Call Trace: __sta_info_destroy+0x2a/0x40 [mac80211] sta_info_destroy_addr_bss+0x38/0x60 [mac80211] ieee80211_del_station+0x1d/0x30 [mac80211] nl80211_del_station+0xe0/0x1f0 [cfg80211] Fix this by copying the ieee80211_key_conf structure for each and every station. This is the easiest way to properly remove the keys with the right index. Another solution would have been to allow several stations to use the same key offset in the firmware. That would require to change the way we track keys in iwlmvm and not really worth it. Also, maintain correctly fw_key_table when we add a key for the multicast station. Remove the key when we remove the multicast station.
