2026-06-14landlock: Add documentation for UDP supportMatthieu Buffet
Add example of UDP usage, without detailing the two access right. Slightly change the example used in code blocks: build a ruleset for a DNS client, so that it uses both TCP and UDP. Test coverage for security/landlock is 91.3% of 2245 lines according to LLVM 22.

2026-06-13devlink: Implement devlink param multi attribute nested data valuesSaeed Mahameed
Devlink param value attribute is not defined since devlink is handling the value validating and parsing internally, this allows us to implement multi attribute values without breaking any policies. Devlink param multi-attribute values are considered to be dynamically sized arrays of u64 values, by introducing a new devlink param type DEVLINK_PARAM_TYPE_U64_ARRAY, driver and user space can set a variable count of u64 values into the DEVLINK_ATTR_PARAM_VALUE_DATA attribute. Implement get/set parsing and add to the internal value structure passed to drivers. This is useful for devices that need to configure a list of values for a specific configuration. example: $ devlink dev param show pci/... name multi-value-param name multi-value-param type driver-specific values: cmode permanent value: 0,1,2,3,4,5,6,7 $ devlink dev param set pci/... name multi-value-param \ value 4,5,6,7,0,1,2,3 cmode permanent Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: Ratheesh Kannoth <rkannoth@marvell.com> Link: https://patch.msgid.link/20260609040453.711932-5-rkannoth@marvell.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2026-06-13landlock: Demonstrate best-effort allowed_access filteringMickaël Salaün
Landlock provides best-effort sandboxing across ABI versions: applications request the rights they need, and on older kernels the unsupported rights are silently dropped from handled_access_* by the documented compatibility switch. The recommended pattern for landlock_add_rule(2) calls is to mirror this filtering at the rule level, which wasn't explicitly described in the exemple. Show the pattern explicitly in the filesystem and network rule examples by masking each rule's allowed_access against the ruleset's handled_access_* and adding the rule only when at least one bit remains set. This makes the recommended best-effort pattern self-documenting.

2026-06-13dpll: add generic DPLL typeGrzegorz Nitka
Add DPLL_TYPE_GENERIC to represent DPLL devices which do not fit the existing PPS or EEC classes. The UAPI type is intentionally generic. During netdev discussion, maintainers pointed out that introducing identifiers tied to a specific placement or single design does not scale across ASICs and vendors. The role of a DPLL is already inferable from the spawning driver, bus device, and pin topology, without encoding additional purpose-specific taxonomy in the type name. Using a generic type keeps the UAPI extensible and avoids premature naming that may become incorrect as new hardware topologies are exposed through the DPLL subsystem. Expose the new type through UAPI and netlink specification as "generic".

The main purpose of this cmd is to be able to associate a non-psp-capable device (e.g. veth or netkit) with a psp device. One use case is if we create a pair of veth/netkit, and assign 1 end inside a netns, while leaving the other end within the default netns, with a real PSP device, e.g. netdevsim or a physical PSP-capable NIC. With this command, we could associate the veth/netkit inside the netns with PSP device, so the virtual device could act as PSP-capable device to initiate PSP connections, and performs PSP encryption/decryption on the real PSP device.

2026-06-12handshake: Require admin permission for DONE commandChuck Lever
ACCEPT and DONE are the two downcalls of the handshake genl family, both intended for use by the trusted handshake agent (tlshd). ACCEPT already requires GENL_ADMIN_PERM; DONE has no privilege check at all. The fd-lookup in handshake_nl_done_doit() only confirms that some pending handshake request exists for the supplied sockfd; it does not authenticate the sender. An unprivileged process that guesses or observes a valid sockfd can therefore submit a DONE with HANDSHAKE_A_DONE_STATUS == 0, leaving the kernel consumer to proceed as if the handshake succeeded. A non-zero status on a forged DONE tears down a legitimate in-flight handshake before tlshd can report its real result.

2026-06-12dt-bindings: hwmon: Add Apple System Management Controller hwmon schemaJames Calligeros
Apple Silicon devices integrate a vast array of sensors, monitoring current, power, temperature, and voltage across almost every part of the system. The sensors themselves are all connected to the System Management Controller (SMC). The SMC firmware exposes the data reported by these sensors via its standard FourCC-based key-value API. The SMC is also responsible for monitoring and controlling any fans connected to the system, exposing them in the same way. For reasons known only to Apple, each device exposes its sensors with an almost totally unique set of keys. This is true even for devices which share an SoC. An M1 Mac mini, for example, will report its core temperatures on different keys to an M1 MacBook Pro. Worse still, the SMC does not provide a way to enumerate the available keys at runtime, nor do the keys follow any sort of reasonable or consistent naming rules that could be used to deduce their purpose. We must therefore know which keys are present on any given device, and which function they serve, ahead of time. Add a schema so that we can describe the available sensors for a given Apple Silicon device in the Devicetree.

2026-06-12modpost: Handle malformed WMI GUID stringsArmin Wolf
Some WMI GUIDs found inside binary MOF files contain both uppercase and lowercase characters. Blindly copying such GUIDs will prevent the associated WMI driver from loading automatically because the WMI GUID found inside WMI device ids always contains uppercase characters. Avoid this issue by always converting WMI GUID strings to uppercase. Also verify that the WMI GUID string actually looks like a valid GUID.

git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm into HEAD KVM/arm64 updates for 7.2 * New features: - None. Zilch. Nada. Que dalle. * Fixes and other improvements: - Significant cleanup of the vgic-v5 PPI support which was merged in 7.1. This makes the code more maintainable, and squashes a couple of bugs in the meantime. - Set of fixes for the handling of the MMU in an NV context, particularly VNCR-triggered faults. S1POE support is fixed as well. - Large set of pKVM fixes, mostly addressing recurring issues around hypervisor tracking of donated pages in obscure cases where the donation could fail and leave things in a bizarre state. - Fixes for the so-called "lazy vgic init", which resulted in sleeping operations in non-preemptible sections. This turned out to be far more invasive than initially expected... - Reduce the overhead of L1/L2 context switch by not touching the FP registers. - Fix the way non-implemented page sizes are dealt with when a guest insist on using them for S2 translation. - The usual set of low-impact fixes and cleanups all over the map.

KVM SVM changes for 7.2 - Add support for virtualizing gPAT (KVM previously just used L1's PAT when running L2). - Fix goofs where KVM mishandles side effects (e.g. single-step and PMC updates) when emulating VMRUN. - Fix a variety of bugs in AVIC's handling of x2APIC MSR interception, most notably where KVM didn't disable interception of IRR, ISR, and TMR regs. - Add support for virtualizing Host-Only/Guest-Only bits in the mediated PMU.

KVM misc x86 changes for 7.2 - Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor code gets a chance to handle things like reaping the PML buffer. - Ensure KVM's copy of CR0 and CR3 are up-to-date on SVM prior to invoking fastpath handlers. - Update KVM's view of PV async enabling if and only if the MSR write fully succeeds. - Fix a variety of issues where the emulator doesn't honor guest-debug state, and clean up related code along the way. - Synthesize EPT Violation and #NPF "error code" bits when injecting faults into L1 that didn't originate in hardware (in which case the VMCS/VMCB doesn't hold relevant information). - Add support for virtualizing (well, emulating) AMD's flavor of CPL>0 CPUID faulting. - Clean up the GPR APIs so that KVM's use of "raw" is consistent, and fix a variety of minor bugs along the way. - Fix an OOB memory access due to not checking the VP ID when handling a Hyper-V PV TLB flush for L2. - Fix a bug in the mediated PMU's handling of fixed counters that allowed the guest to bypass the PMU event filter. - Allow userspace to return EAGAIN when handling SNP and TDX hypercalls, so the KVM can forward a "retry" status code to the guest, and reserve all unused error codes for future usage. - Misc fixes and cleanups.

2026-06-11mptcp: introduce add_addr_v6_port_drop_ts sysctl knobMatthieu Baerts (NGI0)
This sysctl is going to be used in the next commits to drop TCP timestamps option, to be able to send an ADD_ADDR with a v6 IP address and a port number. It is enabled by default. This knob is explicitly disabled in the MPTCP Join selftest, with the "signal addr list progresses after tx drop" subtest, to continue verifying the previous behaviour where the ADD_ADDR is not sent due to a lack of space. While at it, move syn_retrans_before_tcp_fallback down from struct mptcp_pernet, to avoid creating another 3 bytes hole.
