2020-10-12thermal: ti-soc-thermal: Enable addition power managementAdam Ford
The bandgap sensor can be idled when the processor is too, but it isn't currently being done, so the power consumption of OMAP3 boards can elevated if the bangap sensor is enabled. This patch attempts to use some additional power management to idle the clock to the bandgap when not needed.

2020-10-11net: mscc: ocelot: offload VLAN mangle action to VCAP IS1Vladimir Oltean
The VCAP_IS1_ACT_VID_REPLACE_ENA action, from the VCAP IS1 ingress TCAM, changes the classified VLAN. We are only exposing this ability for switch ports that are under VLAN aware bridges. This is because in standalone ports mode and under a bridge with vlan_filtering=0, the ocelot driver configures the switch to operate as VLAN-unaware, so the classified VLAN is not derived from the 802.1Q header from the packet, but instead is always equal to the port-based VLAN ID of the ingress port. We _can_ still change the classified VLAN for packets when operating in this mode, but the end result will most likely be a drop, since both the ingress and the egress port need to be members of the modified VLAN. And even if we install the new classified VLAN into the VLAN table of the switch, the result would still not be as expected: we wouldn't see, on the output port, the modified VLAN tag, but the original one, even though the classified VLAN was indeed modified. This is because of how the hardware works: on egress, what is pushed to the frame is a "port tag", which gives us the following options: - Tag all frames with port tag (derived from the classified VLAN) - Tag all frames with port tag, except if the classified VLAN is 0 or equal to the native VLAN of the egress port - No port tag Needless to say, in VLAN-unaware mode we are disabling the port tag. Otherwise, the existing VLAN tag would be ignored, and a second VLAN tag (the port tag), holding the classified VLAN, would be pushed (instead of replacing the existing 802.1Q tag). This is definitely not what the user wanted when installing a "vlan modify" action. So it is simply not worth bothering with VLAN modify rules under other configurations except when the ports are fully VLAN-aware.

2020-10-11enetc: Migrate to PHYLINK and PCS_LYNXClaudiu Manoil
This is a methodical transition of the driver from phylib to phylink, following the guidelines from sfp-phylink.rst. The MAC register configurations based on interface mode were moved from the probing path to the mac_config() hook. MAC enable and disable commands (enabling Rx and Tx paths at MAC level) were also extracted and assigned to their corresponding phylink hooks. As part of the migration to phylink, the serdes configuration from the driver was offloaded to the PCS_LYNX module, introduced in commit 0da4c3d393e4 ("net: phy: add Lynx PCS module"), the PCS_LYNX module being a mandatory component required to make the enetc driver work with phylink.

2020-10-11bpf: Add redirect_peer helperDaniel Borkmann
Add an efficient ingress to ingress netns switch that can be used out of tc BPF programs in order to redirect traffic from host ns ingress into a container veth device ingress without having to go via CPU backlog queue [0]. For local containers this can also be utilized and path via CPU backlog queue only needs to be taken once, not twice. On a high level this borrows from ipvlan which does similar switch in __netif_receive_skb_core() and then iterates via another_round. This helps to reduce latency for mentioned use cases.

2020-10-10drivers/net/wan/hdlc_fr: Move the skb_headroom check out of fr_hard_headerXie He
Move the skb_headroom check out of fr_hard_header and into pvc_xmit. This has two benefits: 1. Originally we only do this check for skbs sent by users on Ethernet- emulating PVC devices. After the change we do this check for skbs sent on normal PVC devices, too. (Also add a comment to make it clear that this is only a protection against upper layers that don't take dev->needed_headroom into account. Such upper layers should be rare and I believe they should be fixed.) 2. After the change we can simplify the parameter list of fr_hard_header. We no longer need to use a pointer to pointers (skb_p) because we no longer need to replace the skb inside fr_hard_header.

git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can ==================== linux-can-fixes-for-5.9-20201008 The first patch is by Lucas Stach and fixes m_can driver by removing an erroneous call to m_can_class_suspend() in runtime suspend. Which causes the pinctrl state to get stuck on the "sleep" state, which breaks all CAN functionality on SoCs where this state is defined. The last two patches target the j1939 protocol: Cong Wang fixes a syzbot finding of an uninitialized variable in the j1939 transport protocol. I contribute a patch, that fixes the initialization of a same uninitialized variable in a different function. ==================== Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-10-10i2c: owl: Clear NACK and BUS error bitsCristian Ciocaltea
When the NACK and BUS error bits are set by the hardware, the driver is responsible for clearing them by writing "1" into the corresponding status registers. Hence perform the necessary operations in owl_i2c_interrupt().

2020-10-10soc/tegra: pmc: Don't create fake interrupt hierarchy levelsMarc Zyngier
The Tegra PMC driver does ungodly things with the interrupt hierarchy, repeatedly corrupting it by pulling hwirq numbers out of thin air, overriding existing IRQ mappings and changing the handling flow of unsuspecting users. All of this is done in the name of preserving the interrupt hierarchy even when these levels do not exist in the HW. Together with the use of proper IRQs for IPIs, this leads to an unbootable system as the rescheduling IPI gets repeatedly repurposed for random drivers... Instead, let's simply mark the level from which the hierarchy does not make sense for the HW, and let the core code trim the usused levels from the hierarchy.

2020-10-10binder: fix UAF when releasing todo listTodd Kjos
When releasing a thread todo list when tearing down a binder_proc, the following race was possible which could result in a use-after-free: 1. Thread 1: enter binder_release_work from binder_thread_release 2. Thread 2: binder_update_ref_for_handle() -> binder_dec_node_ilocked() 3. Thread 2: dec nodeA --> 0 (will free node) 4. Thread 1: ACQ inner_proc_lock 5. Thread 2: block on inner_proc_lock 6. Thread 1: dequeue work (BINDER_WORK_NODE, part of nodeA) 7. Thread 1: REL inner_proc_lock 8. Thread 2: ACQ inner_proc_lock 9. Thread 2: todo list cleanup, but work was already dequeued 10. Thread 2: free node 11. Thread 2: REL inner_proc_lock 12. Thread 1: deref w->type (UAF) The problem was that for a BINDER_WORK_NODE, the binder_work element must not be accessed after releasing the inner_proc_lock while processing the todo list elements since another thread might be handling a deref on the node containing the binder_work element leading to the node being freed.

2020-10-10staging: comedi: check validity of wMaxPacketSize of usb endpoints foundAnant Thazhemadam
While finding usb endpoints in vmk80xx_find_usb_endpoints(), check if wMaxPacketSize = 0 for the endpoints found. Some devices have isochronous endpoints that have wMaxPacketSize = 0 (as required by the USB-2 spec). However, since this doesn't apply here, wMaxPacketSize = 0 can be considered to be invalid.
