When trying to send the command to abort the scan, since HW rfkill is toggled, the command is not sent due to rfkill being asserted, and -ERFKILL is returned from iwl_trans_send_cmd(), but this is silently ignored in iwl_mvm_send_cmd() and thus the scan abort flow continues to wait for scan complete notification and fails. Since it fails, the UID to type mapping is not cleared, and thus a warning is later fired when trying to stop the interface. To fix this, modify the UMAC scan abort flow to force sending the scan abort command even when in rfkill, so stop the FW from accessing the radio etc. Signed-off-by: Ilan Peer Signed-off-by: Miri Korenblit --- drivers/net/wireless/intel/iwlwifi/mvm/scan.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/scan.c b/drivers/net/wireless/intel/iwlwifi/mvm/scan.c index bed2cd81f8b5..18134e06b021 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/scan.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/scan.c @@ -3249,10 +3249,11 @@ static int iwl_mvm_umac_scan_abort(struct iwl_mvm *mvm, int type) ret = iwl_mvm_send_cmd_pdu(mvm, WIDE_ID(IWL_ALWAYS_LONG_GROUP, SCAN_ABORT_UMAC), - 0, sizeof(cmd), &cmd); + CMD_SEND_IN_RFKILL, sizeof(cmd), &cmd); if (!ret) mvm->scan_uid_status[uid] = type << IWL_MVM_SCAN_STOPPING_SHIFT; + IWL_DEBUG_SCAN(mvm, "Scan abort: ret=%d\n", ret); return ret; }
