2018-03-02iwlwifi: fix malformed CONFIG_IWLWIFI_PCIE_RTPM defaultUlf Magnusson
'default false' should be 'default n', though they happen to have the same effect here, due to undefined symbols ('false' in this case) evaluating to n in a tristate sense. Remove the default instead of changing it. bool and tristate symbols implicitly default to n. Discovered with the https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py script.

2018-03-02iwlwifi: mvm: Correctly set the tid for mcast queueIlan Peer
In the scheduler config command, the meaning of tid == 0xf was intended to indicate the configuration is for management frames. However, tid == 0xf was also used for the multicast queue that was meant only for multicast data frames, which resulted with the FW not encrypting multicast data frames. As multicast frames do not have a QoS header, fix this by setting tid == 0, to indicate that this is a data queue and not management one.

2018-03-02iwlwifi: mvm: Direct multicast frames to the correct stationIlan Peer
Multicast frames for NL80211_IFTYPE_AP and NL80211_IFTYPE_ADHOC were directed to the broadcast station, however, as the broadcast station did not have keys configured, these frames were sent unencrypted. Fix this by using the multicast station which is the station for which encryption keys are configured.

2018-03-02iwlwifi: mvm: fix "failed to remove key" messageSara Sharon
When the GTK is installed, we install it to HW with the station ID of the AP. Mac80211 will try to remove it only after the AP sta is removed, which will result in a failure to remove key since we do not have any station for it. This is a valid situation, but a previous commit removed the early return and added a return with error value, which resulted in an error message that is confusing to users. Remove the error return value.

2018-03-02iwlwifi: avoid collecting firmware dump if not loadedShaul Triebitz
Trying to collect firmware debug data while firmware is not loaded causes various errors (e.g. failing NIC access). This causes even a bigger issue if at that time the HW radio is off. In that case, when later turning the radio on, the Driver fails to read the HW (registers contain garbage values). (It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN bit is cleared on faulty NIC access - since the same behavior was seen in HW RFKILL toggling before setting that bit.)

2018-03-02iwlwifi: mvm: fix assert 0x2B00 on older FWsSara Sharon
We should add the multicast station before adding the broadcast station. However, in older FW, the firmware will start beaconing when we add the multicast station, and since the broadcast station is not added at this point so the transmission of the beacon will fail on assert 0x2b00. This is fixed in later firmware, so make the order of addition depend on the TLV.

2018-03-02iwlwifi: mvm: Fix channel switch for count 0 and 1Andrei Otcheretianski
It was assumed that apply_time==0 implies immediate scheduling, which is wrong. Instead, the fw expects the START_IMMEDIATELY flag to be set. Otherwise, this resulted in 0x3063 assert. Fix that. While at it rename the T2_V2_START_IMMEDIATELY to TE_V2_START_IMMEDIATELY.

2018-03-02iwlwifi: Cancel and set MARKER_CMD timer during suspend-resumeHaim Dreyfuss
While entering to D3 mode there is a gap between the time the driver handles the D3_CONFIG_CMD response to the time the host is going to sleep. In between there might be cases which MARKER_CMD can tailgate. Also during resume flow the MARKER_CMD might get sent while D0I3_CMD is being handled in the FW. Cancel MARKER_CMD timer and set it again properly during suspend resume flows to prevent this command from being sent accidentlly.

2018-03-01Bluetooth: btusb: Add Dell OptiPlex 3060 to btusb_needs_reset_resume_tableKai-Heng Feng
The issue can be reproduced before commit fd865802c66b ("Bluetooth: btusb: fix QCA Rome suspend/resume") gets introduced, so the reset resume quirk is still needed for this system.

2018-03-01Bluetooth: btusb: Remove Yoga 920 from the btusb_needs_reset_resume_tableHans de Goede
Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking"), added the Lenovo Yoga 920 to the btusb_needs_reset_resume_table. Testing has shown that this is a false positive and the problems where caused by issues with the initial fix: commit fd865802c66b ("Bluetooth: btusb: fix QCA Rome suspend/resume"), which has already been reverted. So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at all and this commit removes it from the btusb_needs_reset_resume_table. Note that after this commit the btusb_needs_reset_resume_table is now empty. It is kept around on purpose, since this whole series of commits started for a reason and there are actually broken platforms around, which need to be added to it.

ashmem_mutex create a chain of dependencies like so: (1) mmap syscall -> mmap_sem -> (acquired) ashmem_mmap ashmem_mutex (try to acquire) (block) (2) llseek syscall -> ashmem_llseek -> ashmem_mutex -> (acquired) inode_lock -> inode->i_rwsem (try to acquire) (block) (3) getdents -> iterate_dir -> inode_lock -> inode->i_rwsem (acquired) copy_to_user -> mmap_sem (try to acquire) There is a lock ordering created between mmap_sem and inode->i_rwsem causing a lockdep splat [2] during a syzcaller test, this patch fixes the issue by unlocking the mutex earlier. Functionally that's Ok since we don't need to protect vfs_llseek.

2018-03-01nvme-pci: Fix EEH failure on ppcWen Xiong
Triggering PPC EEH detection and handling requires a memory mapped read failure. The NVMe driver removed the periodic health check MMIO, so there's no early detection mechanism to trigger the recovery. Instead, the detection now happens when the nvme driver handles an IO timeout event. This takes the pci channel offline, so we do not want the driver to proceed with escalating its own recovery efforts that may conflict with the EEH handler. This patch ensures the driver will observe the channel was set to offline after a failed MMIO read and resets the IO timer so the EEH handler has a chance to recover the device.
