iwlwifi: mvm: fix the recovery flow while connecting

2017-07-27T22:10:03+00:00

commit 6b28f9784c394f0692e160f81b07c82cb64af160 upstream. In BSS mode in the disconnection flow, mac80211 removes the AP station before the vif is set to unassociated. Our firmware wants it the other way around: first set the vif as unassociated, and then remove the AP station. In order to bridge between those two different behaviors, iwlmvm doesn't remove the station from the firmware when mac80211 removes it, but only after the vif is set to unassociated. The implementation is in iwl_mvm_bss_info_changed_station: if (assoc state was modified && mvmvif->ap_sta_id is VALID && assoc state is now UNASSC) remove_the_station_from_the_firmware() During the recovery flow, mac80211 re-adds the AP station and then reconfigures the vif. Since the vif is not associated, and then, we enter the if above (which was intended to be taken in the disconnection flow only) and remove the station we just added. This defeats the recovery flow. Fix this by not removing the AP station in this flow if we are in recovery flow. Signed-off-by: Emmanuel Grumbach Signed-off-by: Luca Coelho Signed-off-by: Greg Kroah-Hartman

iwlwifi: fix host command memory leaks

2017-06-05T18:47:10+00:00

Sending host command with CMD_WANT_SKB flag demands the release of the response buffer with iwl_free_resp function. The patch adds the memory release in all the relevant places Signed-off-by: Shahar S Matityahu Signed-off-by: Luca Coelho

iwlwifi: fix min API version for 7265D, 3168, 8000 and 8265

2017-06-05T18:47:10+00:00

In a previous commit, we removed support for API versions earlier than 22 for these NICs. By mistake, the *_UCODE_API_MIN definitions were set to 17. Fix that. Fixes: 4b87e5af638b ("iwlwifi: remove support for fw older than -17 and -22") Signed-off-by: Luca Coelho

iwlwifi: mvm: clear new beacon command template struct

2017-06-05T18:47:09+00:00

Clear the struct so that all reserved fields are zero when we send the struct down to the device. Signed-off-by: Johannes Berg Signed-off-by: Luca Coelho

iwlwifi: mvm: don't fail when removing a key from an inexisting sta

2017-06-05T18:47:09+00:00

The iwl_mvm_remove_sta_key() function handles removing a key when the sta doesn't exist anymore. Mistakenly, this was changed to return an error while fixing another bug. If the mvm_sta doesn't exist, we continue normally, but just don't try to remove the igtk key. Fixes: cd4d23c1ea9b ("iwlwifi: mvm: Fix removal of IGTK") Signed-off-by: Luca Coelho

iwlwifi: pcie: only use d0i3 in suspend/resume if system_pm is set to d0i3

2017-06-05T18:47:08+00:00

We only need to handle d0i3 entry and exit during suspend resume if system_pm is set to IWL_PLAT_PM_MODE_D0I3, otherwise d0i3 entry failures will cause suspend to fail. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=194791 Signed-off-by: Luca Coelho

iwlwifi: mvm: fix firmware debug restart recording

2017-06-05T18:47:08+00:00

When we want to stop the recording of the firmware debug and restart it later without reloading the firmware we don't need to resend the configuration that comes with host commands. Sending those commands confused the hardware and led to an NMI 0x66. Change the flow as following: * read the relevant registers (DBGC_IN_SAMPLE, DBGC_OUT_CTRL) * clear those registers * wait for the hardware to complete its write to the buffer * get the data * restore the value of those registers (to restart the recording) For early start (where the configuration is already compiled in the firmware), we don't need to set those registers after the firmware has been loaded, but only when we want to restart the recording without having restarted the firmware.

iwlwifi: tt: move ucode_loaded check under mutex

2017-06-05T18:47:07+00:00

The ucode_loaded check should be under the mutex, since it can otherwise change state after we looked at it and before we got the mutex. Fix that. Fixes: 5c89e7bc557e ("iwlwifi: mvm: add registration to cooling device") Signed-off-by: Johannes Berg Signed-off-by: Luca Coelho

iwlwifi: mvm: support ibss in dqa mode

2017-06-05T18:47:06+00:00

Allow working IBSS also when working in DQA mode. This is done by setting it to treat the queues the same as a BSS AP treats the queues. Fixes: 7948b87308a4 ("iwlwifi: mvm: enable dynamic queue allocation mode") Signed-off-by: Liad Kaufman Signed-off-by: Luca Coelho

iwlwifi: mvm: Fix command queue number on d0i3 flow

2017-06-05T18:46:10+00:00

During d0i3 flow we flush all the queue except from the command queue. Currently, in this flow the command queue is hard coded to 9. In DQA the command queue number has changed from 9 to 0. Fix that. This fixes a problem in runtime PM resume flow. Fixes: 097129c9e625 ("iwlwifi: mvm: move cmd queue to be #0 in dqa mode") Signed-off-by: Haim Dreyfuss Signed-off-by: Luca Coelho
