2022-05-19dt-bindings: thermal: k3-j72xx: Add VTM bindings documentationKeerthy
Add VTM bindings documentation. In the Voltage Thermal Management Module(VTM), K3 J72XX supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature.

2022-05-19tools/thermal: Add thermal daemon skeletonDaniel Lezcano
This change provides a simple daemon skeleton. It is an example of how to use the thermal library which wraps all the complex code related to the netlink and transforms it into a callback oriented code. The goal of this skeleton is to give a base brick for anyone interested in writing its own thermal engine or as an example to rely on to write its own thermal monitoring implementation. In the future, it will evolve with more features and hopefully more logic.

2022-05-19drm/i915: Fix CFI violation with show_dynamic_id()Nathan Chancellor
When an attribute group is created with sysfs_create_group(), the ->sysfs_ops() callback is set to kobj_sysfs_ops, which sets the ->show() callback to kobj_attr_show(). kobj_attr_show() uses container_of() to get the ->show() callback from the attribute it was passed, meaning the ->show() callback needs to be the same type as the ->show() callback in 'struct kobj_attribute'. However, show_dynamic_id() has the type of the ->show() callback in 'struct device_attribute', which causes a CFI violation when opening the 'id' sysfs node under drm/card0/metrics. This happens to work because the layout of 'struct kobj_attribute' and 'struct device_attribute' are the same, so the container_of() cast happens to allow the ->show() callback to still work. Change the type of show_dynamic_id() to match the ->show() callback in 'struct kobj_attributes' and update the type of sysfs_metric_id to match, which resolves the CFI violation.

This patch fixes a bug where GEN1 VMs doesn't allow resolutions greater than 64 MB size (eg 7680x4320). Unnecessary PCI check limits Gen1 VRAM to legacy PCI BAR size only (ie 64MB). Thus any, resolution requesting greater then 64MB (eg 7680x4320) would fail. MMIO region assigning this memory shouldn't be limited by PCI bar size.

When returning to user space, %rsp is user-controlled value. If it is a SNP-guest and the hypervisor decides to mess with the code-page for this path while a CPU is executing it, a potential #VC could hit in the syscall return path and mislead the #VC handler.

2022-05-19net: bridge: Clear offload_fwd_mark when passing frame up bridge interface.Andrew Lunn
It is possible to stack bridges on top of each other. Consider the following which makes use of an Ethernet switch: br1 / \ / \ / \ br0.11 wlan0 | br0 / | \ p1 p2 p3 br0 is offloaded to the switch. Above br0 is a vlan interface, for vlan 11. This vlan interface is then a slave of br1. br1 also has a wireless interface as a slave. This setup trunks wireless lan traffic over the copper network inside a VLAN. A frame received on p1 which is passed up to the bridge has the skb->offload_fwd_mark flag set to true, indicating that the switch has dealt with forwarding the frame out ports p2 and p3 as needed. This flag instructs the software bridge it does not need to pass the frame back down again. However, the flag is not getting reset when the frame is passed upwards. As a result br1 sees the flag, wrongly interprets it, and fails to forward the frame to wlan0. When passing a frame upwards, clear the flag. This is the Rx equivalent of br_switchdev_frame_unmark() in br_dev_xmit().

In the detach path, the driver calls sysfs_remove_group() for the groups it believes has been registered. However, if the group was never previously registered, then this causes a splat. Instead, compute the groups that should be registered in advance, and then call sysfs_create_groups(), which registers them all at once. Update the error handling appropriately.
