* ath6kl: Add provision to define suspend policy in disconnected state.Raja Mani2012-03-071-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | It gives flexibility to the user to define suspend policy when the suspend mode is set to WOW and the device is in disconnected state at the time of suspend. New module parameter wow_mode is added to get the choice from the user. This parameter is valid only if the module parameter suspend_mode is set to WOW. To force WOW in connected state and cut power in disconnected state: suspend_mode=0x3 wow_mode=0x1 To force WOW in connected state and deep sleep in disconnected state (this is also the default wow_mode): suspend_mode=0x3 wow_mode=0x2 If there is no value specified to wow_mode during insmod, deep sleep mode will be tried in the disconnected state. kvalo: clarified commit log Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| * cfg80211: restructure AP/GO mode APIJohannes Berg2012-02-221-35/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AP/GO mode API isn't very clearly defined, it has "set beacon" and "new beacon" etc. Modify the API to the following: * start AP -- all settings * change beacon -- new beacon data * stop AP -- stop AP mode operation This also reflects in the nl80211 API, rename the commands there correspondingly (but keep the old names for compatibility.) Overall, this makes it much clearer what's going on in the API. Kalle developed the ath6kl changes, I created the rest of the patch.

| | | | | | | | | | | | | | | | | | | | | | | | | | Remove check so that IE in firmware is cleared if not set. Without this fix, any previously set IE will be used incorrectly in the next frame. For example, consider the scenario where a P2P device scan is followed by a regular station scan. The P2P IE set by the P2P scan needs to be cleared, otherwise the station scan will contain the P2P IE. kvalo: indentation fixes Signed-off-by: Aarthi Thiruvengadam <athiruve@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the device get into scan state as soon as a scan request is received, instead of blocking the scan request till the traffic comes down. It is necessary for the deterministic foreground scan particularly when having multiple vif operating where, if the scan is non- deterministic, scan on one interface will not start as long as there are traffic on the other interface.

* ath6kl: Wait for host sleep mode cmd processed event during WOW suspendRaja Mani2012-01-301-0/+15
| | | | | | | | | | | | | | | | | | | | | | For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host), the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as an acknowledgement to the host. In order to being sync with the firmware, the host has to wait for WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to the suspend state. This patch ensures ath6kl_wow_suspend() waits until it gets this event after sending set host sleep mode command. This patch adds, * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in WMI event table. * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx() to process the event. * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record the arrival of the event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First preference is given to the user configured WOW patterns. If the user doesn't configure any patterns (for ex, via iw command), the default patterns will be configured based on the current mode (vif->nw_type) while going to WOW suspend. Summary of changes: * ath6kl_wow_ap() is added to configure the below default patterns when the system enters into WOW suspend in AP mode. + Unicast IP, EAPOL-like and ARP packet pattern + ARP packet pattern + mDNS/SSDP/LLMNR pattern + DHCP broadcast pattern * ath6kl_wow_sta() is added to configure the below default patterns when the system enters into WOW suspend in STA mode. + Unicast packet pattern + mDNS/SSDP/LLMNR pattern * Move the user provided WOW patterns configuration code from ath6kl_wow_suspend() to a separate function called ath6kl_wow_usr(). * Two argument variable's ('filter' and 'mask) data type in ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to 'const u8 *'. This is needed to make all pattern and mask arrays to be 'static const u8' in the caller function. * New conditional check is added to make sure user configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses a few problems with the commit: "ath6kl: Implement support for listen interval from userspace" * The debugfs file required for reading/writing the listen interval wasn't created. Fix this. * The interface index was being hardcoded to zero. Fix this. * Two separate parameters, "listen_interval_time and listen_interval_beacons" were being used. This fails to work as expected because the FW assigns higher precedence to "listen_interval_beacons" and "listen_interval_time" ends up being never used at all. To handle this, fix the host driver to exclusively use listen interval based on units of beacon intervals.

After group formation, the station interface will become a P2P GO/client interface as the case may be. This feature requires modifications to a couple of existing WMI structures and therefore new command ids and structures have been defined in order to be compatible with older firmware versions and other chips. The exception here is the wmi_connect_cmd. Adding a new field to the end of the structure will not cause any issues with previous firmware versions since firmware only checks for minimum length of the command. The other structures are of variable length, hence it was not possible to add new fields to the end. The new command ids have to be added to the end of enum wmi_cmd_id, so it has updated to match the firmware. The driver will support both the 'old' and the 'new' commands for a while by checking the firmware capabilities.

This is legacy from the old staging driver and I can't repoduce the old problem anymore. I assume the bug got fixed while the driver was cleaned up so let's get rid of the hack. This makes it possible to call ath6kl_cfg80211_stop from ath6kl_close() which happens in a followup patch. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is needed to allow WAPI AP to configure the initial group key to the target in the same way as is done with TKIP/CCMP. This fixes broadcast data frame delivery with the initial group key. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the max number of vifs which can be used for non-p2p mode is determined in ath6kl_core_alloc(). But the maximum supported vifs are parsed from firmware IE in ath6kl_fetch_fw_api2() which would happen after ath6kl_core_alloc().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This modparam was introduced to enable non-p2p mode operation on two virtual interfaces. It does not seem to be necessary to have a separate module parameter to do that. Instead, this option can be enabled when any one of the interfaces is not going to be used for p2p (ath6kl_p2p).

* | | ath6kl: Fix AP mode operation after interface down/upVasanthakumar Thiagarajan2011-11-161-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When operating AP interface is brough down the mode is reset to STA. This STA will be reconfigured into AP mode when the interface is brought up again. This sequence will be successful only when change_virtual_intf() returns with no error, but there is a check in this callback which does the type change only when that interface is active. This callback does nothing more than saving the new interface type to vif and wdev, so the sanity check for interface state and wmi state is not necessary. This makes the AP interface functional again after interface down/up. Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
* | | ath6kl: Clear WPS ctrl flag if zero length IE is received from cfg80211Raja Mani2011-11-161-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Connect control flag CONNECT_WPS_FLAG has to be cleared by default even if the driver receives zero length IE from cfg80211. Otherwise this flag would be always set after WPS exchange which would lead wpa_supplicant to fail to connect with the received WPS credentials.
