2012-04-03ath6kl: Fix scan related issue on suspend-resumeVivek Natarajan
When a scan request is pending while going to suspend, any new scan request after resume will fail. So, cancel all scan requests in all the vifs before moving to suspend state.

2012-03-28ath6kl: Store scan request info in-advance before sending SCAN requestRaja Mani
In current code, Scan request info is recorded in vif->scan_req after sending SCAN request to the firmware in ath6kl_cfg80211_scan(). In some corner cases, firmware sends SCAN_COMPLETE event immediately when it receives SCAN request, which internally executes scan complete event handler ath6kl_cfg80211_scan_complete_event() first. So, Scan completion handler will a get a chance to executed even before storing scan request info in ath6kl_cfg80211_scan(). Scan completion handler never report SCAN_COMPLETE event to cfg80211 if scan request info(vif->scan_req) is NULL. This leads to scan failure issue ("Device or resource busy error") during next SCAN request from the user space. This patch ensures that scan request info is stored before sending SCAN request.

2012-03-26ath6kl: Configure inactivity timeout in fwVasanthakumar Thiagarajan
Configure the inactivity timeout passed in start_ap() to firmware. This capability is advertised only when fw supports it, there is a new bit (ATH6KL_FW_CAPABILITY_INACTIVITY_TIMEOUT) in firmware capability ie for driver to learn fw's capability. After the fw finds out the station is inactive, it will probe the station with null func frames. By default, the timeout is 10 secs.

2012-03-20ath6kl: handle probe response from P2P device in P2P GO modeAarthi Thiruvengadam
When the device is in P2P GO mode and in listen state, the correct behavior is to see two different probe response frames - one from P2P device and the other from GO. wpa_supplicant uses the same mechanism to send the frame in both cases (ath6kl_mgmt_tx). For GO probe response, ath6kl needs to call ath6kl_send_go_probe_resp (this will add only WSC/P2P IEs and the rest of the IEs are filled in by the firmware). That was done based on the nw_type == AP_NETWORK which would work if P2P Device role were in a separate netdev. When P2P Device and GO use the same netdev, ath6kl needs to use the special GO probe response case only if SSID is longer than P2P wildcard SSID.

2012-03-07ath6kl: Maintain the listen interval per VIF specificRaja Mani
Firmware has the option to support the listen interval per vif specific. Fix this. Listen interval can be set by the TUs or by the number of beacons. Current code enables the user to configure the listen interval in the unit of 'number of beacons' using debugfs entry "listen_interval". Going forward, we need to alter the listen interval in the unit of TUs to get good power numbers while going to WOW suspend/resume. Allowing the user to change the listen interval in the unit of "number of beacons" in debugfs and changing listen interval in wow suspend/resume in the unit of time (TUs) would lead us to confuse. This patch make sures the listen interval is changed only in the unit of time (TUs). Signed-off-by: Raja Mani <rmani@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2012-03-07ath6kl: Check wow state before sending control and data pktRaja Mani
Below two scenarios are taken care in this patch which helped to fix the firmware crash during wow suspend/resume. * TX operation (ctrl tx and data tx) has to be controlled based on suspend state. i.e, with respect to WOW mode, control packets are allowed to send from the host until the suspend state goes ATH6KL_STATE_WOW and the data packets are allowed until WOW suspend operation starts. * Similarly, wow resume is NOT allowed if WOW suspend is in progress.

2012-03-07ath6kl: Add provision to define suspend policy in disconnected state.Raja Mani
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>

2012-01-30ath6kl: Wait for host sleep mode cmd processed event during WOW suspendRaja Mani
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.

Not handling this case properly results in this panic: BUG: unable to handle kernel NULL pointer dereference at 0000000000000cb0 IP: [<ffffffffa0374e49>] ath6kl_cfg80211_ready+0x9/0x70 [ath6kl_sdio] Call Trace: [<ffffffffa0374ed7>] ath6kl_set_channel+0x27/0x90 [ath6kl_sdio] [<ffffffffa04dfd5f>] cfg80211_set_freq+0xff/0x1d0 [cfg80211] [<ffffffffa04d3275>] ? nl80211_set_wiphy+0x85/0x660 [cfg80211] [<ffffffffa04d3198>] __nl80211_set_channel.isra.39+0x118/0x140 [cfg80211] [<ffffffffa04d34f3>] nl80211_set_wiphy+0x303/0x660 [cfg80211] [<ffffffff813678d7>] ? rtnl_lock+0x17/0x20 [<ffffffffa04ca165>] ? nl80211_pre_doit+0xb5/0x150 [cfg80211] [<ffffffff81382a45>] genl_rcv_msg+0x1d5/0x250 [<ffffffff81382870>] ? genl_rcv+0x40/0x40 [<ffffffff81381be9>] netlink_rcv_skb+0xa9/0xd0 [<ffffffff81382855>] genl_rcv+0x25/0x40 [<ffffffff811354f0>] ? might_fault+0x40/0x90 [<ffffffff81381519>] netlink_unicast+0x2d9/0x320 [<ffffffff813818e6>] netlink_sendmsg+0x2c6/0x320 [<ffffffff81343800>] ? sock_update_classid+0xb0/0x110 [<ffffffff8133f52e>] sock_sendmsg+0x10e/0x130 [<ffffffff81169933>] ? mem_cgroup_update_page_stat+0x193/0x250 [<ffffffff811354f0>] ? might_fault+0x40/0x90 [<ffffffff811354f0>] ? might_fault+0x40/0x90 [<ffffffff81135539>] ? might_fault+0x89/0x90 [<ffffffff811354f0>] ? might_fault+0x40/0x90 [<ffffffff8134d126>] ? verify_iovec+0x56/0xd0 [<ffffffff8133f9e6>] __sys_sendmsg+0x396/0x3b0 [<ffffffff8108e823>] ? up_read+0x23/0x40 [<ffffffff81040e68>] ? do_page_fault+0x208/0x4e0 [<ffffffff81193151>] ? vfsmount_lock_local_unlock+0x21/0x60 [<ffffffff811947d0>] ? mntput_no_expire+0x30/0xe0 [<ffffffff8119489f>] ? mntput+0x1f/0x30 [<ffffffff81342149>] sys_sendmsg+0x49/0x90 [<ffffffff81425482>] system_call_fastpath+0x16/0x1b Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-23ath6kl: Send own IP addr to the firmware during WOW suspendRaja Mani
Firmware ARP module requires own IP addr in order to respond to the outside world when the target is in WOW suspend state. At present, firmware ARP module has capability to hold 2 IP addr. So, WOW mode will be disabled if the total IP addr configured in net_dev for our device is greater than firmware limit (MAX_IP_ADDRS) which is 2 at this moment.

2011-12-23ath6kl: Fix connect command to clear previously used IEsJouni Malinen
Empty IE buffer means that the new association is not supposed to include extra IEs. Make sure any previously configured (Re)Association Request frame IEs get cleared in such a case. This is based on a patch from Shuibing. Cc: Dai Shuibing <shuibing@qca.qualcomm.com> Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2011-12-23ath6kl: Use cfg80211_roamed_bss() to report roaming eventVasanthakumar Thiagarajan
This is to avoid the scenario where the bss entry of the AP got expired when reporting roaming event to current AP. As the bss entry for the current bss is available in driver, pass this bss to cfg80211. This fixes WARNING: at net/wireless/sme.c:586. This patch depends on the following patch in cfg80211 "cfg80211: Fix race in bss timeout".
