2023-08-22cpufreq: amd-pstate-ut: Fix kernel panic when loading the driverSwapnil Sapkal
After loading the amd-pstate-ut driver, amd_pstate_ut_check_perf() and amd_pstate_ut_check_freq() use cpufreq_cpu_get() to get the policy of the CPU and mark it as busy. In these functions, cpufreq_cpu_put() should be used to release the policy, but it is not, so any other entity trying to access the policy is blocked indefinitely. One such scenario is when amd_pstate mode is changed, leading to the following splat: [ 1332.103727] INFO: task bash:2929 blocked for more than 120 seconds.

2023-08-22PM: sleep: Add helpers to allow a device to remain powered-onUlf Hansson
On some platforms a device and its corresponding PM domain, may need to remain powered-on during system wide suspend, to support various use cases. For example, when the console_suspend_enabled flag is unset for a serial controller, the corresponding device may need to remain powered on. Other use cases exists too. In fact, we already have the mechanism in the PM core to deal with these kind of use cases. However, the current naming of the corresponding functions/flags clearly suggests these should be use for system wakeup. See device_wakeup_path(), device_set_wakeup_path and dev->power.wakeup_path. As a way to extend the use of the existing mechanism, let's introduce two new helpers functions, device_awake_path() and device_set_awake_path(). At this point, let them act as wrappers of the existing functions. Ideally, when all users have been converted to use the new helpers, we may decide to drop the old ones and rename the flag.

2023-08-22of: overlay: Extend of_overlay_fdt_apply() to specify the target nodeLizhi Hou
Currently, in an overlay fdt fragment, it needs to specify the exact location in base DT. In another word, when the fdt fragment is generated, the base DT location for the fragment is already known. There is new use case that the base DT location is unknown when fdt fragment is generated. For example, the add-on device provide a fdt overlay with its firmware to describe its downstream devices. Because it is add-on device which can be plugged to different systems, its firmware will not be able to know the overlay location in base DT. Instead, the device driver will load the overlay fdt and apply it to base DT at runtime. In this case, of_overlay_fdt_apply() needs to be extended to specify the target node for device driver to apply overlay fdt. int overlay_fdt_apply(..., struct device_node *base); Signed-off-by: Lizhi Hou <lizhi.hou@amd.com> Link: https://lore.kernel.org/r/1692120000-46900-5-git-send-email-lizhi.hou@amd.com Signed-off-by: Rob Herring <robh@kernel.org>
2023-08-22PCI: Add quirks to generate device tree node for Xilinx Alveo U50Lizhi Hou
The Xilinx Alveo U50 PCI card exposes multiple hardware peripherals on its PCI BAR. The card firmware provides a flattened device tree to describe the hardware peripherals on its BARs. This allows U50 driver to load the flattened device tree and generate the device tree node for hardware peripherals underneath. To generate device tree node for U50 card, add PCI quirks to call of_pci_make_dev_node() for U50.

2023-08-22PCI: Create device tree node for bridgeLizhi Hou
The PCI endpoint device such as Xilinx Alveo PCI card maps the register spaces from multiple hardware peripherals to its PCI BAR. Normally, the PCI core discovers devices and BARs using the PCI enumeration process. There is no infrastructure to discover the hardware peripherals that are present in a PCI device, and which can be accessed through the PCI BARs. Apparently, the device tree framework requires a device tree node for the PCI device. Thus, it can generate the device tree nodes for hardware peripherals underneath. Because PCI is self discoverable bus, there might not be a device tree node created for PCI devices. Furthermore, if the PCI device is hot pluggable, when it is plugged in, the device tree nodes for its parent bridges are required. Add support to generate device tree node for PCI bridges. Add an of_pci_make_dev_node() interface that can be used to create device tree node for PCI devices. Add a PCI_DYNAMIC_OF_NODES config option. When the option is turned on, the kernel will generate device tree nodes for PCI bridges unconditionally. Initially, add the basic properties for the dynamically generated device tree nodes which include #address-cells, #size-cells, device_type, compatible, ranges, reg.

2023-08-22bpf: Fix check_func_arg_reg_off bug for graph root/nodeKumar Kartikeya Dwivedi
The commit being fixed introduced a hunk into check_func_arg_reg_off that bypasses reg->off == 0 enforcement when offset points to a graph node or root. This might possibly be done for treating bpf_rbtree_remove and others as KF_RELEASE and then later check correct reg->off in helper argument checks. But this is not the case, those helpers are already not KF_RELEASE and permit non-zero reg->off and verify it later to match the subobject in BTF type. However, this logic leads to bpf_obj_drop permitting free of register arguments with non-zero offset when they point to a graph root or node within them, which is not ok. For instance: struct foo { int i; int j; struct bpf_rb_node node; }; struct foo *f = bpf_obj_new(typeof(*f)); if (!f) ... bpf_obj_drop(f); // OK bpf_obj_drop(&f->i); // still ok from verifier PoV bpf_obj_drop(&f->node); // Not OK, but permitted right now Fix this by dropping the whole part of code altogether.

2023-08-22Revert "wifi: mac80211_hwsim: check the return value of nla_put_u32"Johannes Berg
This reverts commit b970ac68e0c4 ("wifi: mac80211_hwsim: check the return value of nla_put_u32") since it introduced a memory leak in the error path, which seems worse than sending an incomplete skb, and the put can't fail anyway since the SKB was just allocated.

2023-08-22mac80211: make ieee80211_tx_info padding explicitArnd Bergmann
While looking at a bug, I got rather confused by the layout of the 'status' field in ieee80211_tx_info. Apparently, the intention is that status_driver_data[] is used for driver specific data, and fills up the size of the union to 40 bytes, just like the other ones. This is indeed what actually happens, but only because of the combination of two mistakes: - "void *status_driver_data[18 / sizeof(void *)];" is intended to be 18 bytes long but is actually two bytes shorter because of rounding-down in the division, to a multiple of the pointer size (4 bytes or 8 bytes). - The other fields combined are intended to be 22 bytes long, but are actually 24 bytes because of padding in front of the unaligned tx_time member, and in front of the pointer array. The two mistakes cancel out. so the size ends up fine, but it seems more helpful to make this explicit, by having a multiple of 8 bytes in the size calculation and explicitly describing the padding.
