2014-10-29Bluetooth: Wrong style spin lock usedJukka Rissanen1-3/+7
Use spin_lock_bh() as the code is called from softirq in networking subsystem. This is needed to prevent deadlocks when 6lowpan link is in use. Signed-off-by: Jukka Rissanen <[email protected]> Signed-off-by: Marcel Holtmann <[email protected]>
2014-10-29iwlwifi: mvm: unref SCAN ref on scan completionEliad Peller1-1/+6
The scan reference wasn't released in case of offloaded scan, causing the refcount to go wrong and prevent the device from going into d0i3. Signed-off-by: Eliad Peller <[email protected]> Reviewed-by: Johannes Berg <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: rs: add Tx STBC supportEyal Shapira2-9/+68
STBC is enabled on HT/VHT SISO rates in case we don't care about power consumption and it won't hurt BT. This is done only in case the peer and our chip support STBC of course. While at it fixed a bug which was causing bw and ldpc flags to be set incorrectly in the rate scale table in case we are switching to a legacy Tx column. This had no real impact.

2014-10-29iwlwifi: mvm: fix scan condition iteratorDavid Spinadel1-1/+2
Scan condition iterator assumes that an interface is associated if phy_ctxt is assigned, but this isn't the sutuation in P2P device. OTOH P2P device is never associated so we can simply ignore it. Signed-off-by: David Spinadel <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: port to devcoredump frameworkJohannes Berg7-112/+55
iwlwifi features a debug mechanism that allows to dump binary data which is helpful to debug the firmware. Until now, this data was made available for the userspace through debugfs. For this exact purpose, devcoredump was created. Move to the new infrastructure. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: enable STBC support for 8000 chipsEyal Shapira1-0/+1
These chips support STBC in both Tx and Rx. Given that we've added STBC Tx support enable it. Signed-off-by: Eyal Shapira <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: dvm: Fix probable mask then right shift defectJoe Perches1-2/+2
Precedence of & and >> is not the same and is not left to right. shift has higher precedence and should be done after the mask. Add parentheses around the mask. Signed-off-by: Joe Perches <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: remove unnecessary includes in tt.cLuciano Coelho1-4/+0
We used to need to include some headers in order to read the registers and do all the calculations by ourselves, but this is not done anymore (i.e. we let the firmware do this for us), so we don't need to include those headers anymore.

2014-10-29iwlwifi: mvm: flush queues without mutex heldJohannes Berg1-6/+12
For WMM-AC we may have to be changing QoS parameters while the queues are being flushed. This is not relevant in the "drop" case, but matters when we wait for the device to finish the transmissions. To allow this, do the actual waiting without holding the mutex. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: improve MCS rate warningJohannes Berg1-2/+4
The warning gives no information about the frame, and presents the flags so that one might think they're the frame. Clarify and add more information. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>

2014-10-29iwlwifi: mvm: add MVM_FW_BCAST_FILTER_PASS_ALL optionMax Stepanov2-1/+5
The MVM_FW_BCAST_FILTER_PASS_ALL option defined in iwl-dbg-cfg.ini configuration file allows to enable/disable FW broadcast filtering. If MVM_FW_BCAST_FILTER_PASS_ALL is not defined in iwl-dbg-cfg.ini or its value is 0, the mvm broadcast filtering is enabled. Setting MVM_FW_BCAST_FILTER_PASS_ALL=1 in iwl-dbg-cfg.ini blocks sending of BCAST_FILTER_CMD to FW.

2014-10-29iwlwifi: always run the secured flow for family 8000Eran Harary4-10/+14
In the new format the "CSS section" has the same TLV type as the "mem section". So we need to run the secured flow for all the 8000 products. Signed-off-by: Eran Harary <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: pcie: fix recovery from ARC reset in WoWLANEmmanuel Grumbach1-9/+8
When the ARC is reset when we exit from Sx in case we had WoWLAN running, we can't access the prph before we reset the NIC. Reviewed-by: Johannes Berg <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: pcie: warn if extern fw_debug buffer failedEmmanuel Grumbach1-1/+1

2014-10-29iwlwifi: mvm: change the iwl_mvm_d3_iface_iterator into a generic functionLuciano Coelho3-43/+43
Getting the BSS station vif is something that may be needed by other parts of the code. So, instead of having an iterator specifically for d3, change it into a generic one in utils.c. Additionally, add a iwl_mvm_get_bss_vif() function to make it easier to retrieving it. Signed-off-by: Luciano Coelho <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: add debugfs entry to configure netdetect SSIDsLuciano Coelho4-0/+142
Before we get all the chain (ie. mac80211, cfg80211, nl80211 and userspace) changed to support net-detect, we can use this debugfs entry for easy testing and as a proof of concept. Signed-off-by: Luciano Coelho <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: spin off a function to start scan offloadLuciano Coelho3-18/+31
The net-detect feature will require a scan offload to be started in the same way it is done now for scheduled scan. Spin a new function off of the sched_scan_start op code for reuse. Additionally, restructure the function a bit for more readability. Signed-off-by: Luciano Coelho <[email protected]> Signed-off-by: Emmanuel Grumbach <[email protected]>
2014-10-29iwlwifi: mvm: move the check if associated outside of the iterator for wowlanLuciano Coelho1-23/+25
Instead of checking if we are associated when suspending with wowlan enabled in the interface iterator, allow it to return an unassociated vif and move the check to the main suspend function. This will be needed by netdetect, since it should also work when we are not associated but the vif is active.

2014-10-29iwlwifi: mvm: split wowlan handling out of the main suspend functionLuciano Coelho1-115/+151
Take the WoWLAN handling code out of the main suspend function, dividing it into three parts: get_config (which is used before the firmware is switched), switch_to_d3 (which handles the rebooting of the hardware with the D3 firmware) and config (which configures the D3 firmware for WoWLAN operation). This is necessary to prepare for the net-detect implementation, which will use only the switch_to_d3 part of this flow.

2014-10-29iwlwifi: mvm: hold the rtnl when resuming from a d3 testLuciano Coelho1-0/+2
We use ieee80211_iter_keys() which requires the rtnl to be held. If we don't lock the rtnl, like we do when we suspend during a d3 test, we get the following splat: RTNL: assertion failed at net/mac80211/key.c (566) CPU: 1 PID: 26529 Comm: cat Tainted: G W O 3.10.29-dev #1 Hardware name: Dell Inc.

2014-10-28mac802154: add synchronization handlingAlexander Aring1-0/+7
This patch adds synchronization handling in start and stop driver ops calls. This patch is mostly grab from mac80211 which was introduced by commit ea77f12f2cc0f31168f2e0259e65a22202ac4dc2 ("mac80211: remove tasklet enable/disable").

2014-10-28mac802154: move local started handlingAlexander Aring3-26/+4
This patch removes the current handling of started boolean. This is actually dead code, because mac802154_netdev_register can't never be called before ieee802154_register_hw. This means that local->started is always be true when mac802154_netdev_register is called. Instead we using this now like mac80211 to indicate that an instance of sdata is running.

2014-10-28mac802154: rework sdata state change to runningAlexander Aring2-8/+16
This patch reworks the handling for setting the state like mac80211. We use bit's instead a bool variable. The mutex is not needed because it use test and set bits which are atomic operations. Signed-off-by: Alexander Aring <[email protected]> Signed-off-by: Marcel Holtmann <[email protected]>
2014-10-28mac802154: remove driver ops in wpan-phyAlexander Aring4-116/+8

2014-10-28mac802154: introduce driver-ops headerAlexander Aring1-0/+202
This patch introduce a driver-ops header file with function wrappers to call the driver ops. These wrappers checking on right context information and warn if optional driver ops are called when these aren't implemented. This behaviour is like mac80211 driver-ops header file, just without function tracing calls. Signed-off-by: Alexander Aring <[email protected]> Signed-off-by: Marcel Holtmann <[email protected]>
2014-10-28mac802154: ops: declare channel and page as u8Alexander Aring5-11/+9

2014-10-28Bluetooth: Fix check for direct advertisingJohan Hedberg1-1/+1
These days we allow simultaneous LE scanning and advertising. Checking for whether advertising is enabled or not is therefore not a reliable way to determine whether directed advertising was used to trigger the connection creation. The appropriate place to check (instead of the hdev context) is the connection role that's stored in the hci_conn. This patch fixes such a check in le_conn_timeout() which could otherwise lead to incorrect HCI commands being sent.

2014-10-28Bluetooth: Fix LE connection timeout deadlockJohan Hedberg1-1/+1
The le_conn_timeout() may call hci_le_conn_failed() which in turn may call hci_conn_del(). Trying to use the _sync variant for cancelling the conn timeout from hci_conn_del() could therefore result in a deadlock. This patch converts hci_conn_del() to use the non-sync variant so the deadlock is not possible.
