2018-12-20iwlwifi: mvm: remove dead codeSara Sharon
In iwl_mvm_tx_skb_non_sta(), in case of managed interface, the AP station was supposed to be used for multicast frames instead of the auxiliary station to avoid frames possibly sent to an absent P2P GO. However, when moving to DQA mode, this was broken as no valid queue was assigned. This is fixed by a recent patch that directs all non-offchannel traffic to ap station earlier in the TX path. However, the broken, and now dead code, remained. Remove it.

2018-12-20cw1200: Fix concurrency use-after-free bugs in cw1200_hw_scan()Jia-Ju Bai
The function cw1200_bss_info_changed() and cw1200_hw_scan() can be concurrently executed. The two functions both access a possible shared variable "frame.skb". This shared variable is freed by dev_kfree_skb() in cw1200_upload_beacon(), which is called by cw1200_bss_info_changed(). The free operation is protected by a mutex lock "priv->conf_mutex" in cw1200_bss_info_changed(). In cw1200_hw_scan(), this shared variable is accessed without the protection of the mutex lock "priv->conf_mutex". Thus, concurrency use-after-free bugs may occur. To fix these bugs, the original calls to mutex_lock(&priv->conf_mutex) and mutex_unlock(&priv->conf_mutex) are moved to the places, which can protect the accesses to the shared variable.

2018-12-19mlxsw: spectrum_router: Make RIF deletion more robustIdo Schimmel
In the past we had multiple instances where RIFs were not properly deleted. One of the reasons for leaking a RIF was that at the time when IP addresses were flushed from the respective netdev (prompting the destruction of the RIF), the netdev was no longer a mlxsw upper. This caused the inet{,6}addr notification blocks to ignore the NETDEV_DOWN event and leak the RIF. Instead of checking whether the netdev is our upper when an IP address is removed, we can instead check if the netdev has a RIF configured. To look up a RIF we need to access mlxsw private data, so the patch stores the notification blocks inside a mlxsw struct. This then allows us to use container_of() and extract the required private data.

Next patch is going to make RIF deletion more robust by removing reliance on fragile mlxsw_sp_lower_get(). This is because a netdev is not necessarily our upper anymore when its IP addresses are flushed. The inet{,6}addr notification blocks are going to resolve 'struct mlxsw_sp' using container_of(), but the functions they call still use mlxsw_sp_lower_get(). As a preparation for the next patch, propagate 'struct mlxsw_sp' down to the functions called from the notification blocks and remove reliance on mlxsw_sp_lower_get().

2018-12-19mlxsw: spectrum: Properly cleanup LAG uppers when removing port from LAGIdo Schimmel
When a LAG device or a VLAN device on top of it is enslaved to a bridge, the driver propagates the CHANGEUPPER event to the LAG's slaves. This causes each physical port to increase the reference count of the internal representation of the bridge port by calling mlxsw_sp_port_bridge_join(). However, when a port is removed from a LAG, the corresponding leave() function is not called and the reference count is not decremented. This leads to ugly hacks such as mlxsw_sp_bridge_port_should_destroy() that try to understand if the bridge port should be destroyed even when its reference count is not 0. Instead, make sure that when a port is unlinked from a LAG it would see the same events as if the LAG (or its uppers) were unlinked from a bridge. The above is achieved by walking the LAG's uppers when a port is unlinked and calling mlxsw_sp_port_bridge_leave() for each upper that is enslaved to a bridge.

2018-12-19mlxsw: spectrum: Remove reference count from VLAN entriesIdo Schimmel
Commit b3529af6bb0d ("spectrum: Reference count VLAN entries") started reference counting port-VLAN entries in a similar fashion to the 8021q driver. However, this is not actually needed and only complicates things. Instead, the driver should forbid the creation of a VLAN on a port if this VLAN already exists. This would also solve the issue fixed by the mentioned commit. Therefore, remove the get()/put() API and use create()/destroy() instead. One place that needs special attention is VLAN addition in a VLAN-aware bridge via switchdev operations. In case the VLAN flags (e.g., 'pvid') are toggled, then the VLAN entry already exists. To prevent the driver from wrongly returning EEXIST, the driver is changed to check in the prepare phase whether the entry already exists and only returns an error in case it is not associated with the correct bridge port.

In commit 993107fea5ee ("mlxsw: spectrum_switchdev: Fix VLAN device deletion via ioctl") I fixed a bug caused by the fact that the driver views differently the deletion of a VLAN device when it is deleted via an ioctl and netlink. Instead of relying on a specific order of events (device being unregistered vs. VLAN filter being updated), simply make sure that the driver performs the necessary cleanup when the VLAN device is unlinked, which always happens before the other two events.

2018-12-19mlxsw: spectrum_router: Do not destroy RIFs based on FID's reference countIdo Schimmel
Currently, when a RIF is constructed on top of a FID, the RIF increments the FID's reference count and the RIF is destroyed when the FID's reference count drops to 1. This effectively means that when no local ports are member in the FID, the FID is destroyed regardless if the router port is a member in the FID or not. The above can lead to the unexpected behavior in which routes using a VLAN interface as their nexthop device are no longer offloaded after the last local port leaves the corresponding VLAN (FID). Example: # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload # bridge vlan del vid 10 dev swp3 # ip -4 route show dev br0.10 192.0.2.0/24 proto kernel scope link src 192.0.2.1 After the patch, the route is offloaded before and after the VLAN is removed from local port 'swp3', as the RIF corresponding to 'br0.10' continues to exists. In order to remove RIFs' reliance on the underlying FID's reference count, we need to add a reference count to sub-port RIFs, which are RIFs that correspond to physical ports and their uppers (e.g., LAG devices). In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to hold a reference on the RIF. For example: bond0.10 | bond0 | +-------+ | | swp1 swp2 Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the RIF corresponding to 'bond0.10'. When the last reference is dropped, the RIF will be destroyed. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Reviewed-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.

secpath_set is a wrapper for secpath_dup that will not perform an allocation if the secpath attached to the skb has a reference count of one, i.e., it doesn't need to be COW'ed.

If the host driver sends the quiet mode setting command to the HL2.0 firmware, it crashes with the below signature. fatal error received: err_qdi.c:456:EX:wlan_process:1:WLAN RT:207a:PC=b001b4f0 The quiet mode command support is exposed by the firmware via thermal throttle wmi service. Enable ath10k thermal support if thermal throttle wmi service bit is set. 10.x firmware versions support this feature by default, but unfortunately do not advertise the support via service flags, hence have to manually set the service flag in ath10k_core_compat_services(). Tested on QCA988X with 10.2.4.70.9-2. Also tested on WCN3990.

2018-12-19Bluetooth: hci_bcm: Handle specific unknown packets after firmware loadingJonathan Bakker
The Broadcom controller on aries S5PV210 boards sends out a couple of unknown packets after the firmware is loaded. This will cause logging of errors such as: Bluetooth: hci0: Frame reassembly failed (-84) This is probably also the case with other boards, as there are related Android userspace patches for custom ROMs such as https://review.lineageos.org/#/c/LineageOS/android_system_bt/+/142721/ Since this appears to be intended behaviour, treated them as diagnostic packets.

2018-12-19drivers/regulator: fix a missing check of return valueKangjie Lu
If palmas_smps_read() fails, we should not use the read data in "reg" which may contain random value. The fix inserts a check for the return value of palmas_smps_read(): If it fails, we return the error code upstream and stop using "reg".

2018-12-19genirq/core: Introduce struct irq_affinity_descDou Liyang
The interrupt affinity management uses straight cpumask pointers to convey the automatically assigned affinity masks for managed interrupts. The core interrupt descriptor allocation also decides based on the pointer being non NULL whether an interrupt is managed or not. Devices which use managed interrupts usually have two classes of interrupts: - Interrupts for multiple device queues - Interrupts for general device management Currently both classes are treated the same way, i.e. as managed interrupts. The general interrupts get the default affinity mask assigned while the device queue interrupts are spread out over the possible CPUs. Treating the general interrupts as managed is both a limitation and under certain circumstances a bug. Assume the following situation: default_irq_affinity = 4..7 So if CPUs 4-7 are offlined, then the core code will shut down the device management interrupts because the last CPU in their affinity mask went offline. It's also a limitation because it's desired to allow manual placement of the general device interrupts for various reasons. If they are marked managed then the interrupt affinity setting from both user and kernel space is disabled. To remedy that situation it's required to convey more information than the cpumasks through various interfaces related to interrupt descriptor allocation. Instead of adding yet another argument, create a new data structure 'irq_affinity_desc' which for now just contains the cpumask. This struct can be expanded to convey auxilliary information in the next step. No functional change, just preparatory work.

2018-12-19PM-runtime: Switch autosuspend over to using hrtimersVincent Guittot
PM-runtime uses the timer infrastructure for autosuspend. This implies that the minimum time before autosuspending a device is in the range of 1 tick included to 2 ticks excluded -On arm64 this means between 4ms and 8ms with default jiffies configuration -And on arm, it is between 10ms and 20ms These values are quite high for embedded systems which sometimes want the duration to be in the range of 1 ms. It is possible to switch autosuspend over to using hrtimers to get finer granularity for short durations and take advantage of slack to retain some margins and get long timeouts with minimum wakeups. On an arm64 platform that uses 1ms for autosuspending timeout of its GPU, idle power is reduced by 10% with hrtimer. The latency impact on arm64 hikey octo cores is: - mark_last_busy: from 1.11 us to 1.25 us - rpm_suspend: from 15.54 us to 15.38 us [Only the code path of rpm_suspend() that starts hrtimer has been measured.] arm64 image (arm64 default defconfig) decreases by around 3KB with following details: $ size vmlinux-timer text data bss dec hex filename 12034646 6869268 386840 19290754 1265a82 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 12030550 6870164 387032 19287746 1264ec2 vmlinux The latency impact on arm 32bits snowball dual cores is : - mark_last_busy: from 0.31 us usec to 0.77 us - rpm_suspend: from 6.83 us to 6.67 usec The increase of the image for snowball platform that I used for testing performance impact, is neglictable (244B). $ size vmlinux-timer text data bss dec hex filename 7157961 2119580 264120 9541661 91981d build-ux500/vmlinux size vmlinux-hrtimer text data bss dec hex filename 7157773 2119884 264248 9541905 919911 vmlinux-hrtimer And arm 32bits image (multi_v7_defconfig) increases by around 1.7KB with following details: $ size vmlinux-timer text data bss dec hex filename 13304443 6803420 402768 20510631 138f7a7 vmlinux $ size vmlinux-hrtimer text data bss dec hex filename 13304299 6805276 402768 20512343 138fe57 vmlinux Signed-off-by: Vincent Guittot <vincent.guittot@linaro.org> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Rafael J.
