Commit 4ea7e38696c7 ("dropmon: add ability to detect when hardware drops rx packets") introduced is_drop_point_hw, but the symbol was never referenced anywhere in the kernel tree and is currently not used by dropwatch. I could not find, to the best of my abilities, a current out-of-tree user of this macro.

So, some venders are using menu style, some venders are listed each drivers on top page, etc. It is difficult to find target vender and/or drivers because it is very random. Let's standardize ASoC menu, like below --- ALSA for SoC audio support Analog Devices ---> AMD ---> Apple ---> Atmel ---> Au1x ---- Broadcom ---> Cirrus Logic ---> DesignWare ---> Freescale ---> Google ---> Hisilicon ---> ...

2025-06-24alpha: regularize the situation with asm/param.hAl Viro
The only reason why alpha can't do what sparc et.al. are doing is that include/asm-generic/param.h relies upon the value of HZ set for userland header in uapi/asm/param.h being 100. We need that value to define USER_HZ and we need that definition to outlive the redefinition of HZ kernel-side. And alpha needs it to be 1024, not 100 like everybody else. So let's add __USER_HZ to uapi/asm-generic/param.h, defaulting to 100 and used to define HZ. That way include/asm-generic/param.h can use that thing instead of open-coding it - it won't be affected by undefining and redefining HZ. That done, alpha asm/param.h can be removed and uapi/asm/param.h switched to defining __USER_HZ and EXEC_PAGESIZE and then including <asm-generic/param.h> - asm/param.h will resolve to uapi/asm/param.h, which pulls <asm-generic/param.h>, which will do the right thing both in the kernel and userland contexts.

When a request for getting RTS threshold for a particular radio is received, parse the radio id and get the required data.

2025-06-24wifi: cfg80211/mac80211: Add support to get radio indexRoopni Devanathan
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

2025-06-23io_uring/netcmd: add tx timestamping cmd supportPavel Begunkov
Add a new socket command which returns tx time stamps to the user. It provide an alternative to the existing error queue recvmsg interface. The command works in a polled multishot mode, which means io_uring will poll the socket and keep posting timestamps until the request is cancelled or fails in any other way (e.g. with no space in the CQ). It reuses the net infra and grabs timestamps from the socket's error queue. The command requires IORING_SETUP_CQE32. All non-final CQEs (marked with IORING_CQE_F_MORE) have cqe->res set to the tskey, and the upper 16 bits of cqe->flags keep tstype (i.e. offset by IORING_CQE_BUFFER_SHIFT). The timevalue is store in the upper part of the extended CQE. The final completion won't have IORING_CQE_F_MORE and will have cqe->res storing 0/error.

2025-06-23fs: introduce FALLOC_FL_WRITE_ZEROES to fallocateZhang Yi
With the development of flash-based storage devices, we can quickly write zeros to SSDs using the WRITE_ZERO command if the devices do not actually write physical zeroes to the media. Therefore, we can use this command to quickly preallocate a real all-zero file with written extents. This approach should be beneficial for subsequent pure overwriting within this file, as it can save on block allocation and, consequently, significant metadata changes, which should greatly improve overwrite performance on certain filesystems. Therefore, introduce a new operation FALLOC_FL_WRITE_ZEROES to fallocate. This flag is used to convert a specified range of a file to zeros by issuing a zeroing operation. Blocks should be allocated for the regions that span holes in the file, and the entire range is converted to written extents. If the underlying device supports the actual offload write zeroes command, the process of zeroing out operation can be accelerated. If it does not, we currently don't prevent the file system from writing actual zeros to the device. This provides users with a new method to quickly generate a zeroed file, users no longer need to write zero data to create a file with written extents. Users can determine whether a disk supports the unmap write zeroes feature through querying this sysfs interface: /sys/block/<disk>/queue/write_zeroes_unmap_max_hw_bytes Users can also enable or disable the unmap write zeroes operation through this sysfs interface: /sys/block/<disk>/queue/write_zeroes_unmap_max_bytes Finally, this flag cannot be specified in conjunction with the FALLOC_FL_KEEP_SIZE since allocating written extents beyond file EOF is not permitted. In addition, filesystems that always require out-of-place writes should not support this flag since they still need to allocated new blocks during subsequent overwrites.

GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>, <ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>, <Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and <Instruction.WRMSR>. They must be supported by VMM to support TDX guests. For GetTdVmCallInfo - When leaf (r12) to enumerate TDVMCALL functionality is set to 0, successful execution indicates all GHCI base TDVMCALLs listed above are supported. Update the KVM TDX document with the set of the GHCI base APIs. - When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it indicates the TDX guest is querying the supported TDVMCALLs beyond the GHCI base TDVMCALLs. Exit to userspace to let userspace set the TDVMCALL sub-function bit(s) accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s) supported by itself when the TDVMCALLs don't need support from userspace after returning from userspace and before entering guest.

2025-06-20KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>Binbin Wu
Handle TDVMCALL for GetQuote to generate a TD-Quote. GetQuote is a doorbell-like interface used by TDX guests to request VMM to generate a TD-Quote signed by a service hosting TD-Quoting Enclave operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in a shared-memory area as parameter. Host VMM can access it and queue the operation for a service hosting TD-Quoting enclave. When completed, the Quote is returned via the same shared-memory area. KVM only checks the GPA from the TDX guest has the shared-bit set and drops the shared-bit before exiting to userspace to avoid bleeding the shared-bit into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU) and userspace VMM queues the operation asynchronously. KVM sets the return code according to the 'ret' field set by userspace to notify the TDX guest whether the request has been queued successfully or not. When the request has been queued successfully, the TDX guest can poll the status field in the shared-memory area to check whether the Quote generation is completed or not. When completed, the generated Quote is returned via the same buffer. Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is required to handle the KVM exit reason as the initial support for TDX, by reentering KVM to ensure that the TDVMCALL is complete. While at it, add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

2025-06-20wifi: cfg80211: Add support for link reconfiguration negotiation offload to ↵Kavita Kavita
driver In the case of SME-in-driver, the driver can internally choose to update the links based on the AP MLD recommendation and do link reconfiguration negotiation with AP MLD. (e.g., After the driver processing the BSS Transition Management request frame received from the AP MLD with Neighbor Report containing Multi-Link element with recommended links information chooses to do link reconfiguration negotiation with AP MLD). To support this, extend cfg80211_mlo_reconf_add_done() and NL80211_CMD_ASSOC_MLO_RECONF to indicate added links information for driver-initiated link reconfiguration requests. For removed links, the driver indicates links information using the NL80211_CMD_LINKS_REMOVED event for driver-initiated cases, the same as supplicant initiated cases. For the driver-initiated case, cfg80211 will receive link reconfiguration result asynchronously from driver so holding BSSes of the accepted add links is needed in the event path. Also, no need of unhold call for the rejected add link BSSes since there was no hold call happened previously. Once the supplicant receives the NL80211_CMD_ASSOC_MLO_RECONF event, it needs to process the information about newly added links and install per-link group keys (e.g., GTK/IGTK/BIGTK etc.). In case of the SME-in-driver, using a vendor interface etc. to notify the supplicant to initiate a link reconfiguration request and then supplicant sending command to the cfg80211 can lead to race conditions. The correct design to avoid this is that the driver indicates the cfg80211 directly with the results of the link reconfiguration negotiation.

2025-06-19time: Introduce auxiliary POSIX clocksAnna-Maria Behnsen
To support auxiliary timekeeping and the related user space interfaces, it's required to define a clock ID range for them. Reserve 8 auxiliary clock IDs after the regular timekeeping clock ID space. This is the maximum number of auxiliary clocks the kernel can support. The actual number of supported clocks depends obviously on the presence of related devices and might be constraint by the available VDSO space. Add the corresponding timekeeper IDs as well.

2025-06-18net: pse-pd: Add support for budget evaluation strategiesKory Maincent (Dent Project)
This patch introduces the ability to configure the PSE PI budget evaluation strategies. Budget evaluation strategies is utilized by PSE controllers to determine which ports to turn off first in scenarios such as power budget exceedance. The pis_prio_max value is used to define the maximum priority level supported by the controller. Both the current priority and the maximum priority are exposed to the user through the pse_ethtool_get_status call. This patch add support for two mode of budget evaluation strategies. 1. Static Method: This method involves distributing power based on PD classification. It’s straightforward and stable, the PSE core keeping track of the budget and subtracting the power requested by each PD’s class. Advantages: Every PD gets its promised power at any time, which guarantees reliability. Disadvantages: PD classification steps are large, meaning devices request much more power than they actually need. As a result, the power supply may only operate at, say, 50% capacity, which is inefficient and wastes money. Priority max value is matching the number of PSE PIs within the PSE. 2. Dynamic Method: To address the inefficiencies of the static method, vendors like Microchip have introduced dynamic power budgeting, as seen in the PD692x0 firmware. This method monitors the current consumption per port and subtracts it from the available power budget. When the budget is exceeded, lower-priority ports are shut down. Advantages: This method optimizes resource utilization, saving costs. Disadvantages: Low-priority devices may experience instability. Priority max value is set by the PSE controller driver. For now, budget evaluation methods are not configurable and cannot be mixed. They are hardcoded in the PSE driver itself, as no current PSE controller supports both methods.

2025-06-17vxlan: Support MC routing in the underlayPetr Machata
Locally-generated MC packets have so far not been subject to MC routing. Instead an MC-enabled installation would maintain the MC routing tables, and separately from that the list of interfaces to send packets to as part of the VXLAN FDB and MDB. In a previous patch, a ip_mr_output() and ip6_mr_output() routines were added for IPv4 and IPv6. All locally generated MC traffic is now passed through these functions. For reasons of backward compatibility, an SKB (IPCB / IP6CB) flag guards the actual MC routing. This patch adds logic to set the flag, and the UAPI to enable the behavior.
