Linus Torvalds	aab799b1bd	soc: devicetree updates for 7.2 ... There are fewer devicetree updates this time that the last few ones, with five SoC types getting added: - Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using four Cortex-A55 and one Cortex-A78 core, which is a significant upgrade from older generations - ZTE zx297520v3 is an older low-end wireless SoC using a single Cortex-A53 core, which so far can only run 32-bit kernels. This brings back the ZX family of chips that was removed in 2021 after support for the original zx296702 and zx296718 chips was never completed. - Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N (R8A77965) automotive SoC. - Apple t8122 (M3) is the 2023 generation of their laptop SoCs, which has now been reverse-engineered to the point of having initial kernel support for five laptop models. - ASPEED AST27xx is their first baseboard managment controller using a 64-bit core, the Cortex-A35, following earlier generations using ARMv5/v6/v7 CPUs. These all come with one or more initial boards, and in total there are 39 new boards getting added across SoC families, including: - Two NAS boxes using the old Cortina Systems Gemini SoC based on an ARMv4 FA526 CPU core - 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A SoCs from Variscite, Toradex and SolidRun, plus a number of overlays for combinations with additional boards - One new carrier board and SoM using TI K3 AM62x, in addition to new overlays for older SoMs - Two new boards using Spacemit K3 (no relation with TI) RISC-V SoCs. - Three phones from Google, Nothing and Motorola, all using Qualcomm Snapdragon SoCs - AST26xx BMC support for two server boards While there is still a significant number of patches improving hardware support for the existing boards across vendors (NXP, Qualcomm, Renesas, Rockchips, Mediatek, ...), a much smaller number of cleanups and warning fixes have made it in this time. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmovyQ0ACgkQmmx57+YA GNmE2hAAk4UguDtXr6fCYcIiBGqEtKhPmuvD98edmRyemg1x3ZbHIZn52rUqKFoz HDi1BL7NkKdDuIWJ5DvqyHGLMg6kCEbiYSsjdkjN2Hcsx+I8NtokCR0hRtteNPQ9 f6kgDj9+VsWvXTsYKFU87qkK1bC5nVrLS7xxIuuCIYxULvSEX5GGJbHQ93qxNUam 6GrFcDHnozh9OfETSBw9bME16FiMxapgghPxMaAmVzuB+iGr4xyrEHmyu9gThsuJ O2P04LIhu9j9CZOjaJ54+v41AtMIVE7xG1+MUC5JcWBc7OMVLE30uGgsW9jBKaii Wsxa3D08+m1JYeFbhJR6tWAf4HbIEpudEoJmlSdwRhvYte15kU90f917aTNFYBow sBf6G09t4ZLsDr9NzCx+cWUnoVLdlYv4auRGNxoWsxe4ed9G6c+yiZN2pBaFNXuT wNJqrFstS9mszBaPItgt4e5Tck+IB0uKNqhbSWa3rFyKrXQ9SpZOKVN6cPlwFjhT wWYZcAzUL8n2Sz71l/U/QqjN6hqnZWFghe9B3wr81/XQ4sPjWHWoTeRfnees+vFM LtE77TGPW2KdZpRI38qfyKWWH3PwKaTtZ07ne8NOvh60zmhK+uUFGzzWAhKlO/Z2 a3tX8evXRTOb5NrvWzGlwpPwtE0R71oRIwxG1MlmFdlJzddI4Xc= =EhYX -----END PGP SIGNATURE----- Merge tag 'soc-dt-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull SoC devicetree updates from Arnd Bergmann: "There are fewer devicetree updates this time that the last few ones, with five SoC types getting added: - Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using four Cortex-A55 and one Cortex-A78 core, which is a significant upgrade from older generations - ZTE zx297520v3 is an older low-end wireless SoC using a single Cortex-A53 core, which so far can only run 32-bit kernels.

Linus Torvalds	056e065a6b	sound updates for 7.2-rc1 ... Unsurprisingly, we've had a fairly busy development cycle with various fixes and enhancements. While the majority of changes consist of device-specific fixes, a significant number of cleanups, hardening, and modernizations have been applied to the core frameworks as well. Below are some highlights: * ALSA Core: - Hardening, race condition, and UAF/leak fixes in the ALSA timer and sequencer cores - Widespread adoption of flexible array members across core structures - Integration of new simple refcount helper functions to simplify code * ASoC Core: - Introduction of a unified SoundWire enumeration helper to clean up redundant device initialization across codecs - Enhancements to SDCA support, including handling devices with multiple functions of the same type and proper jack reporting masks - Continued refactoring of ASoC component debugfs and DAPM structures - Simplification and improvements to the format auto-selection mechanism - Added shared BCLK rate constraints for cross-DAI coordination * ASoC Platforms & Codecs: - Initial bring-up and power management support for AMD ACP 7.x - Support for Everest Semi ES9356 (SDCA), Mediatek MT2701 (on-chip HDMI) and MT8196 SoCs, Renesas RZ/G3E, SpacemiT K3, and TI TAC5xx2/TAS67524 - Added a new generic driver for GPIO-driven amplifiers - Continued mass conversion of locking code to guard() helpers across numerous platform drivers (MediaTek, Rockchip, STM32, Samsung, etc.) - Cleanup of legacy non-DT platform data and rollbacks for obsolete SH Ecovec24/7724se boards * HD- and USB-Audio: - Device-specific hardware quirks and fixes for various Realtek HD-Audio devices (Lenovo, HP, ASUS, Acer, Clevo) - Refinements to Qualcomm USB-audio offloading support - Front-panel controls and autogain status support for Scarlett Gen 4 - Quirks for XIBERIA (K03S), Sennheiser (MOMENTUM 3), Edifier (MF200), Novation (Mininova), and Behringer (Flow 8) USB-audio devices - Improved robustness by rolling back or propagating write errors to the mixer control caches (Babyface Pro, US-16x08, Scarlett) * Others: - Support for the HT-Omega eClaro PCI sound card in the Oxygen driver - Robustness improvements and fixes for Virtio-audio, Xen-front, and legacy OSS dmasound drivers -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmoxPGIOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE+wOA/+IVmz8RuySkrOpVkKepK4lVCbG3oZM1twTFkh YNhOOGWAjueCTfhuiTHadrg0eP4hKsO2Padu2OEFp6aZLH8zJI7UCinoRuvQ8yep gmQs0rsMsLkYd8JCDJjC+6kltvhigbKkrWza8FgBHu1fxJ0PQuhwKhUW/vrP4OsM 7HrGP2lmaWHetRh8v9NxzhJWrUgqXtpklmUZJQvnIHe5ER752I6fO3QaKjLMJ+O1 EBIjpA1kP8kw0z8yvW3RAmfAyrGB5J4AnLDZ5AmPf61v+xPgy3FsqbbWRC0CDCZB 5KC2/AToDNOXPUbUqVKEv6lj6c6dhxf6+1zqcCYokMA1bsiCsnU2jtYsX9DOZjWw qs+MDLkcYRlol2UZrOCRkJZkfqqaKsIqUE3P+MaTJdgTspMrl9Bd0M3TzGLe6Kxi 4HpA3+z1yNSWvUEwDTpXjKIg1Qni7NsfNLZHzYDCd2UW/sAV5pD0phEXRveVerTL qxeL3Fwmil2ApeTEwdXqdXiaDs9DV2wQU1hPfukOXiUYSXAYhSA+D4NIWmWPs4nU WsgcMo/Tq8GdapE2KxulOS4KuMddhxCZAg2UQAERPVAz61UlkbXJ15P7A8xKEm3h PhPOlKzH9tzsDjG2zPwnkxLLNvHfbBJjbpy6tvi45qhKWptG4nuiYcxfhnGogi63 367P/Wg= =wMnQ -----END PGP SIGNATURE----- Merge tag 'sound-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "Unsurprisingly, we've had a fairly busy development cycle with various fixes and enhancements.

Linus Torvalds	b85966adbf	Networking changes for 7.2. ... Core & protocols ---------------- - Work on removing rtnl_lock protection throughout the stack continues. In this chapter: - don't use rtnl_lock for IPv6 multicast routing configuration - don't take rtnl_lock in ethtool for modern drivers - prepare Qdisc dump callbacks for rtnl_lock removal - Support dumping just ifindex + name of all interfaces, under RCU. It's a common operation for Netlink CLI tools (when translating names to ifindexes) and previously required full rtnl_lock. - Support dumping qdiscs and page pools for a specific netdev. Even tho user space wants a dump of all netdevs, most of the time, the OOO programming model results in repeating the dump for each netdev. Which, in absence of a cache, leads to a O(n^2) behavior. - Flush nexthops once on multi-nexthop removal (e.g. when device goes down), another O(n^2) -> O(n) improvement. - Rehash locally generated traffic to a different nexthop on retransmit timeout. - Honor oif when choosing nexthop for locally generated IPv6 traffic. - Convert TCP Auth Option to crypto library, and drop non-RFC algos. - Increase subflow limits in MPTCP to 64 and endpoint limit to 256. - Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need to selectively skip reporting of the standard TCP Timestamp option, because they won't fit into the header space together (12 + 30 > 40). - Support using bridge neighbor suppression, Duplicate Address Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN deployments, e.g. VXLAN fabrics (IPv4 and IPv6). - Improve link state reporting for upper netdevs (e.g. macvlan) over tunnel devices (again, mostly for EVPN deployments). - Support binding GENEVE tunnels to a local address. - Speed up UDP tunnel destruction (remove one synchronize_rcu()). - Support exponential field encoding in multicast (IGMPv3 and MLDv2). - Support attaching PSP crypto offload to containers (veth, netkit). - Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows migrating individual IPsec SAs independently of their policies. The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA migration, lacks SPI for unique SA identification, and cannot express reqid changes or migrate Transport mode selectors. The new interface identifies the SA via SPI and mark, supports reqid changes, address family changes, encap removal, and uses an atomic create+install flow under x->lock to prevent SN/IV reuse during AEAD SA migration. - Implement GRO/GSO support for PPPoE. - Convert sockopt callbacks in a number of protocols to iov_iter. Cross-tree stuff ---------------- - Remove support for Crypto TFM cloning (unblocked after the TCP Auth Option rework). This feature regressed performance for all crypto API users, since it changed crypto transformation objects into reference- -counted objects. - Add FCrypt-PCBC implementation to rxrpc and remove it from the global crypto API as obsolete and insecure. Wireless -------- - Major rework of station bandwidth handling, fixing issues with lower capability than AP. - Cleanups for EMLSR spec issues (drafts differed). - More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast, schedule improvements, multi-station etc.) - Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work (e.g. non-primary channel access, UHR DBE support). - Fine Timing Measurement ranging (i.e. distance measurement) APIs. Netfilter --------- - Use per-rule hash initval in nf_conncount. This avoids unnecessary lock contention with short keys (e.g. conntrack zones) in different namespaces. - Various safety improvements, both in packet parsing and object lifetimes. Notably add refcounts to conntrack timeout policy. Deletions --------- - Remove TLS + sockmap integration. TLS wants to pin user pages to avoid a copy, and sockmap wants to write to the input stream. More work on this integration is clearly needed, and we can't find any users (original author admitted that they never deployed it). - Remove support for TLS offload with TCP Offload Engine (the far more common opportunistic offload is retained). The locking looks unfixable (driver sleeps under TCP spin locks) and people from the vendor that added this are AWOL. - Remove more ATM code, trying to leave behind only what PPPoATM needs, AAL5 and br2684 with permanent circuits. - Remove AppleTalk. Let it join hamradio in our out of tree protocol graveyard, I mean, repository. - Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel) interface in user namespaces. To be deleted completely, soon. - Remove 5/10 MHz support from cfg80211/mac80211. Drivers ------- - Software: - Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit). - bonding: add knob to strictly follow 802.3ad for link state. - New drivers: - Alibaba Elastic Ethernet Adaptor (cloud vNIC). - NXP NETC switch within i.MX94. - DPLL: - Add operational state to pins (implement in zl3073x). - Add generic DPLL type, for daisy-chaining DPLLs (implement in ice). - Ethernet high-speed NICs: - Huawei (hinic3): - enhance tc flow offload support with queue selection, tunnels - nVidia/Mellanox: - avoid over-copying payload to the skb's linear part (up to 60% win for LRO on slow CPUs like ARM64 V2) - expose more per-queue stats over the standard API - support additional, unprivileged PFs in the DPU configuration - support Socket Direct (multi-PF) with switchdev offloads - add a pool / frag allocator for DMA mapped buffers for control objects, save memory on systems with 64kB page size - take advantage of the ability to dynamically change RSS table size, even when table is configured by the user - increase the max RSS table size for even traffic distribution - Ethernet NICs: - Marvell/Aquantia: - AQC113 PTP support - Realtek USB (r8152): - support 10Gbit Link Speeds and Energy-Efficient Ethernet (EEE) - support firmware loaded (for RTL8157/RTL8159) - support for the RTL8159 - Intel (ixgbe): - support Energy-Efficient Ethernet (EEE) on E610 devices - Ethernet switches: - Airoha: - support multiple netdevs on a single GDM block / port - Marvell (mv88e6xxx): - support SERDES of mv88e6321 - Microchip (ksz8/9): - rework the driver callbacks to remove one indirection layer - Motorcomm (yt921x): - support port rate policing - support TBF qdisc offload - support ACL/flower offload - nVidia/Mellanox: - expose per-PG rx_discards - Realtek: - rtl8365mb: bridge offloading and VLAN support - Ethernet PHYs: - Airoha: - support Airoha AN8801R Gigabit PHYs. - Micrel: - implement 3 low-loss cable tunables - Realtek: - support MDI swapping for RTL8226-CG - support MDIO for RTL931x - Qualcomm: - at803x: Rx and Tx clock management for IPQ5018 PHY - Motorcomm: - support YT8522 100M RMII PHY - set drive strength in YT8531s RGMII - TI: - dp83822: add optional external PHY clock - Bluetooth: - hci_sync: add support for HCI_LE_Set_Host_Feature [v2] - SMP: use AES-CMAC library API - Intel: - support Product level reset - support smart trigger dump - Mediatek: - add event filter to filter specific event - Realtek: - fix RTL8761B/BU broken LE extended scan - WiFi: - Broadcom (b43): - new support for a 11n device - MediaTek (mt76): - support mt7927 - mt792x: broken usb transport detection - mt7921: regulatory improvements - Qualcomm (ath9k): - GPIO interface improvements - Qualcomm (ath12k): - WDS support - replace dynamic memory allocation in WMI Rx path - thermal throttling/cooling device support - 6 GHz incumbent interference detection - channel 177 in 5 GHz - Realtek (rt89): - RTL8922AU support - USB 3 mode switch for performance - better monitor radiotap support - RTL8922DE preparations Signed-off-by: Jakub Kicinski <kuba@kernel.org> -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE6jPA+I1ugmIBA4hXMUZtbf5SIrsFAmox1O4ACgkQMUZtbf5S Irve7hAAgvCYRFvQ/1dvL+PORg2KqVW4rWXMvNrEWaMVAEXJIIPJoxen6zn6a/72 aRs2Ord/wVM/Uh291TOrARwtv1U0oOvOvnbrVM2u06o/EqjtxRAZSF9quTlPdm6Q RvlkR5X9XXM2MwbDc1zYNTITfhVv80YDCFmYGI7O8dyhLuyspX2eU0SiW33Twl4f y6RLcn12gyUbDpa6vt+tari6cFCO/X2zot/uwaDY38b+kwsMHunrj3/PSfJzeYIU 5mD7jG+xsPxQlEskMYGOjVT5VeMdRquhb9UGwoostZpuEPYZfzTdFtphC1qZqIPk 8O8ngAW1yYNIY9TTMPF3Y3LMpOiyZq6/P4KY+tksbeDw8vvTYJzEgw3VpwurZQLM vfHKDj1kM6VLNekeCI+2cip06flVH3jtIkN0KOERwzTSS8NUbs6PuoEP0HLdjafj cr/pgSSTQPUsQkpS5R5Ld3bwpnKea56CQ36p2E8JvU2akwK5RnvqiZiTAfz2z2Tg M0NVlTsJ07ucNBxsO4l7osDtRTnzUqo+ZeTo+zR5l0cGRXPd9nJByk257z4IAlcQ 2MHrJmCZ+ZFKhmkUNUPBdFBATbRgOZHzA/iiiThBrT2hDvWQ2kygO9+IkJBS/WYx eQz7G9hb6Xn1ifWVvPVD0oDL3DKKTotQIN90PZCzvObQFWMc1Vk= =oNfE -----END PGP SIGNATURE----- Merge tag 'net-next-7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core & protocols: - Work on removing rtnl_lock protection throughout the stack continues.

Jakub Kicinski	8a398a0c18	appletalk: move the protocol out of tree ... AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009, according to Wikipedia. We recently got a burst of AI generated fixes to this protocol which nobody is reviewing. Let AppleTalk follow AX.25 and hamradio out of the Linux tree. We we will maintain the code at: github.com/linux-netdev/mod-orphan for anyone interested in playing with it. Retain the uAPI for now. No strong reason, simply because I suspect keeping it will be less controversial.

Linus Torvalds	764e77d868	Locking updates for v7.2: ... Futex updates: - Optimize futex hash bucket access patterns (Peter Zijlstra) - Large series to address the robust futex unlock race for real, by Thomas Gleixner: "The robust futex unlock mechanism is racy in respect to the clearing of the robust_list_head::list_op_pending pointer because unlock and clearing the pointer are not atomic. The race window is between the unlock and clearing the pending op pointer. If the task is forced to exit in this window, exit will access a potentially invalid pending op pointer when cleaning up the robust list. That happens if another task manages to unmap the object containing the lock before the cleanup, which results in an UAF. In the worst case this UAF can lead to memory corruption when unrelated content has been mapped to the same address by the time the access happens. User space can't solve this problem without help from the kernel. This series provides the kernel side infrastructure to help it along: 1) Combined unlock, pointer clearing, wake-up for the contended case 2) VDSO based unlock and pointer clearing helpers with a fix-up function in the kernel when user space was interrupted within the critical section. ... with help by André Almeida: - Add a note about robust list race condition (André Almeida) - Add self-tests for robust release operations (André Almeida) Context analysis updates: - Implement context analysis for 'struct rt_mutex'.

The race window is between the unlock and clearing the pending op pointer. If the task is forced to exit in this window, exit will access a potentially invalid pending op pointer when cleaning up the robust list. That happens if another task manages to unmap the object containing the lock before the cleanup, which results in an UAF. In the worst case this UAF can lead to memory corruption when unrelated content has been mapped to the same address by the time the access happens. User space can't solve this problem without help from the kernel. This series provides the kernel side infrastructure to help it along: 1) Combined unlock, pointer clearing, wake-up for the contended case 2) VDSO based unlock and pointer clearing helpers with a fix-up function in the kernel when user space was interrupted within the critical section. ... with help by André Almeida: - Add a note about robust list race condition (André Almeida) - Add self-tests for robust release operations (André Almeida) Context analysis updates: - Implement context analysis for 'struct rt_mutex'.

Linus Torvalds	2d6d57f889	Updates for NTP/timekeeping and PTP: ... - Expand timekeeping snapshot mechanisms The various snapshot functions are mostly used for PTP to collect "atomic" snapshots of various involved clocks. They lack support for the recently introduced AUX clocks and do not provide the underlying counter value (e.g. TSC) to user space. Exposing the counter value snapshot allows for better control and steering. Convert the hard wired ktime_get_snapshot() to take a clock ID, which allows the caller to select the clock ID to be captured along with CLOCK_MONONOTONIC_RAW. Additionally capture the underlying hardware counter value and the clock source ID of the counter. Expand the hardware based snapshot capture where devices provide a mechanism to snapshot the hardware PTP clock and the system counter (usually via PCI/PTM) to support AUX clocks and also provide the captured counter value back to the caller and not only the clock timestamps derived from it. - Add a new optional read_snapshot() callback to clocksources That is required to capture atomic snapshots from clocksources which are derived from TSC with a scaling mechanism (e.g. Hyper-V, KVMclock). The value pair is handed back in the snapshot structure to the callers, so they can do the necessary correlations in a more precise way. This touches usage sites of the affected functions and data structure all over the tree, but stays fully backwards compatible for the existing user space exposed interfaces. New PTP IOCTLs will provide access to the extended functionality in later kernel versions. -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmotoSAQHHRnbHhAa2Vy bmVsLm9yZwAKCRCmGPVMDXSYoYWbEACv/g3pGDxWxfzOI2h6vQgGxDvD3LwmdhPE bzXRRaxp3/J0rZTQmCghknVGDPVjepNQgKkUMXfaFG2UZmiPHG5qVTXO6DddguS4 cQc0SUO3e422lUPCoBmTULZ+vlctb4LJsWXPQHYNKC73KqMJtWte7T2HBiFDK5RB O0S34DZtkvOW4tHIu0RwlwCXZ0gcO+zsjxKA8K/P6sMtKBQU1/rRkZZCx2KCvq0F Rx3NTGoY4if/C83YBq1cEn8BvXrcQQH4ZOOWuySsLGJGRPZ1dXGP+JtfRWutk/f9 HZztlaXcEz71dJXlhBxc0Eb/86uC3POEq7ZYvQdzLbsSZ/3AbalksL9CLyxgdHtc U964SuwOVPcYfEytd4TWb1nu7JgOR0olYK+l4AbCt4EdKst5TADCJ7rtlZV3Idp+ Yg1GN3TwJcKItUNX9Szk+7MbvB8EWOEl7Obahfm48qDK1pqFe08qhOzSCeRXu+Bb QiupC3ndzUB1Yjf3DPV6wQl4Fl/TscrAVrPlnGCOJEKXtUKFxvcKquy/W29UD//w NuxKO2zK05UDsbBEwnZiCrdSGGNiLBYUbHfx2UvA7M0rfrrbjmG4rCFPotxhNb54 UuqgdM8G45MkyBV3qSSh3VC0XeD7UqzQtMYgUjjhvtapLlsri69vzL2DnQUcajSG dgjzIg9O3g== =kBrz -----END PGP SIGNATURE----- Merge tag 'timers-ptp-2026-06-13' of gitolite.kernel.org:pub/scm/linux/kernel/git/tip/tip Pull timekeeping updates from Thomas Gleixner: "Updates for NTP/timekeeping and PTP: - Expand timekeeping snapshot mechanisms The various snapshot functions are mostly used for PTP to collect "atomic" snapshots of various involved clocks.

Registration data is instead scoped structurally to the Registration object, making lifecycle ordering enforced by construction rather than convention. - Rust-native device driver lifetimes (HRT): - Allow Rust device drivers to carry a lifetime parameter on their bus device private data, tied to the device binding scope -- the interval during which a bus device is bound to a driver. Device resources like pci::Bar<'a> and IoMem<'a> can be stored directly in the driver's bus device private data with a lifetime bounded by the binding scope, so the compiler enforces at build time that they do not outlive the binding. This removes Devres indirection from every access site and eliminates try_access() failure paths in destructors. Bus driver traits use a Generic Associated Type (GAT) Data<'bound> to introduce the lifetime on the private data, rather than parameterizing the Driver trait itself. Auxiliary registration data, where the lifetime is not introduced by a trait callback but must be threaded through Registration, uses the ForLt trait (a type-level abstraction for types generic over a lifetime). - Misc: - Fix DT overlayed devices not probing by reverting the broken treewide overlay fix and re-running fw_devlink consumer pickup when an overlay is applied to a bound device - Use root_device_register() for faux bus root device; add sanity check for failed bus init - Fix dev_has_sync_state() data race with READ_ONCE() and move it to base.h - Avoid spurious device_links warning when removing a device while its supplier is unbinding - Switch ISA bus to dynamic root device - Fix suspicious RCU usage in kernfs_put() - Remove devcoredump exit callback - Constify devfreq_event_class -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQS2q/xV6QjXAdC7k+1FlHeO1qrKLgUCai1lNQAKCRBFlHeO1qrK LjX1AP4kEb6SJdvBFlG/IJcG9vyqA7+Cig8OIlx9vEX7e7GvNwEAxL2HltAlAd5Q cOIJOlu0uM+j1mn0JyuM9b0WJrxDLAA= =E5mG -----END PGP SIGNATURE----- Merge tag 'driver-core-7.2-rc1' of gitolite.kernel.org:pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core updates from Danilo Krummrich: "Deferred probe: - Fix race where deferred probe timeout work could be permanently canceled by using mod_delayed_work() - Fix missing jiffies conversion in deferred_probe_extend_timeout() - Guard timeout extension with delayed_work_pending() to prevent premature firing - Use system_percpu_wq instead of the deprecated system_wq - Update deferred_probe_timeout documentation device: - Replace direct struct device bitfield access (can_match, dma_iommu, dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent, of_node_reused, offline, offline_disabled) with flag-based accessors using bit operations - Reject devices with unregistered buses - Delete unused DEVICE_ATTR_PREALLOC() - Add low-level device attribute macros with const show/store callbacks, allowing device attributes to reside in read-only memory - Move core device attributes to read-only memory - Constify group array pointers in driver_add_groups() / driver_remove_groups(), struct bus_type, and struct device_driver device property: - Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id() - Initialize all fields of fwnode_handle in fwnode_init() - Provide swnode_get()/swnode_put() wrappers around kobject_get/put() - Allow passing struct software_node_ref_args pointers directly to PROPERTY_ENTRY_REF() driver_override: - Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override infrastructure, fixing a UAF from unsynchronized access to driver_override in bus match() callbacks - Remove the now-unused driver_set_override() firmware loader: - Fix recursive lock deadlock in device_cache_fw_images() when async work falls back to synchronous execution - Fix device reference leak in firmware_upload_register() platform: - Pass KBUILD_MODNAME through the platform driver registration macro to create module symlinks in sysfs for built-in drivers; move module_kset initialization to a pure_initcall and tegra cbb registration to core_initcall to ensure correct ordering - Pass THIS_MODULE implicitly through a coresight_init_driver() macro sysfs: - Upgrade OOB write detection in sysfs_kf_seq_show() from printk to WARN - Add return value clamping to sysfs_kf_read() Rust: - ACPI: Fix missing match data for PRP0001 by exporting acpi_of_match_device() - Auxiliary: Replace drvdata() with dedicated registration data on auxiliary_device. drvdata() exposed the driver's bus device private data beyond the driver's own scope, creating ordering constraints and forcing the data to outlive all registrations that access it.

The allocation can sleep doing direct reclaim and runs memcg charging, which extends the critical section and stalls any concurrent reader on the same mutex. Now up to 8 pages are pre-allocated before the mutex is taken, leftovers are recycled into the per-pipe tmp_page[] cache before unlock, and any remainder is released after unlock, keeping the allocator out of the critical section on both sides. On a writers x readers sweep with 64KB writes against a 1 MB pipe throughput improves 6-28% and average write latency drops 5-22%; under memory pressure - when the cost of holding the mutex across reclaim is highest - throughput improves 21-48% and latency drops 17-33%. The microbenchmark is added to selftests. - uaccess/sockptr: fix the ignored_trailing logic in copy_struct_to_user() to behave as documented and the usize check in copy_struct_from_sockptr() for user pointers, and add copy_struct_{from,to}_bounce_buffer() and copy_struct_to_sockptr() helpers for upcoming users (IPPROTO_SMBDIRECT, IPPROTO_QUIC). - bpf: add a sleepable bpf_real_inode() kfunc that resolves the real inode backing a dentry via d_real_inode(). On overlayfs the inode attached to the dentry doesn't carry the underlying device information; this is used by the filesystem restriction BPF program that was merged into systemd. - docs: add guidelines for submitting new filesystems, motivated by the maintenance burden abandoned and untestable filesystems impose on VFS developers, blocking infrastructure work like folio conversions and iomap migration. Fixes: - libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo() and drop the now-redundant assignments in callers. This began as a one-line dma-buf fix for a path_noexec() warning; a pseudo filesystem has no reason not to set SB_I_NOEXEC. All init_pseudo() callers were audited: the only visible effect is on dma-buf where SB_I_NOEXEC silences the warning. - Handle set_blocksize() failures in legacy filesystems (bfs, hpfs, qnx4, jfs, befs, affs, isofs, minix, ntfs3, omfs). Mounting a device with a sector size > PAGE_SIZE crashed roughly half of them; the rest had the same missing error handling pattern. Plus a follow-up releasing the superblock buffer_head when setting the minix v3 block size fails. - mount: honour SB_NOUSER in the new mount API. - fs/fcntl: fix a SOFTIRQ-unsafe lock order in fasync signaling by switching the process-group paths of send_sigio() and send_sigurg() from read_lock(&tasklist_lock) to RCU, matching the single-PID path. - vfs: add an FS_USERNS_DELEGATABLE flag and set it for NFS, fixing delegated NFS mounts (fsopen() in a container with the mount performed by a privileged daemon) that broke when non-init s_user_ns was tied to FS_USERNS_MOUNT. - selftests/namespaces: fix a hang in nsid_test where an unreaped grandchild kept the TAP pipe write-end open, a waitpid(-1) race in listns_efault_test, and a false FAIL on kernels without listns() where the tests should SKIP. - filelock: fix the break_lease() stub signature for CONFIG_FILE_LOCKING=n. - init/initramfs_test: wait for the async initramfs unpacking before running; the test and do_populate_rootfs() share the parser state. - fs/coredump: reduce redundant log noise in validate_coredump_safety(). - iomap: pass the correct length to fserror_report_io() in __iomap_write_begin(). - backing-file: fix the backing_file_open() kerneldoc. Cleanups: - initramfs: refactor the cpio hex header parsing to use hex2bin() instead of the hand-rolled simple_strntoul() which is reverted, and extend the initramfs KUnit tests to cover header fields with 0x prefixes. - Replace __get_free_pages() and friends with kmalloc()/kzalloc() across quota, proc, ocfs2/dlm, nilfs2, nfs, nfsd, libfs, jfs, jbd2, isofs, fuse, select, namespace, configfs, binfmt_misc, bfs, and the do_mounts init code - part of the larger work of replacing page allocator calls with kmalloc(). - Use clear_and_wake_up_bit() in unlock_buffer() and journal_end_buffer_io_sync() instead of open-coding the sequence. - Drop unused VFS exports: unexport drop_super_exclusive(), remove start_removing_user_path_at(), and fold __start_removing_path() into start_removing_path(). - fs/read_write: narrow the __kernel_write() export with EXPORT_SYMBOL_FOR_MODULES(). - vfs: uapi: retire octal and hex constants in favor of (1 << n) for the O_ flags. Finding a free bit for a new flag across the architectures was needlessly hard with the mixed bases. - dcache: add extra sanity checks of dead dentries in dentry_free() via a new DENTRY_WARN_ONCE() that also prints d_flags. - iov_iter: use kmemdup_array() in dup_iter() to harden the allocation against multiplication overflow. - fs/pipe: write to ->poll_usage only once. - vfs: remove an always-taken if-branch in find_next_fd(). - dcache: use kmalloc_flex() for struct external_name in __d_alloc(). - namei: use QSTR() instead of QSTR_INIT() in path_pts(). - sync_file_range: delete dead S_ISLNK code. - Comment fixes: retire a stale comment in fget_task_next() and fix assorted spelling mistakes" * tag 'vfs-7.2-rc1.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: (73 commits) backing-file: fix backing_file_open() kerneldoc parameter iomap: pass the correct len to fserror_report_io in __iomap_write_begin vfs: add FS_USERNS_DELEGATABLE flag and set it for NFS filelock: fix break_lease() stub signature for CONFIG_FILE_LOCKING=n vfs: uapi: retire octal and hex numbers in favor of (1 << n) for O_ flags bpf: add bpf_real_inode() kfunc fs/read_write: Do not export __kernel_write() to the entire world libfs: drop redundant SB_I_NOEXEC/SB_I_NODEV in init_pseudo() callers libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo() mount: honour SB_NOUSER in the new mount API fs/fcntl: fix SOFTIRQ-unsafe lock order in fasync signaling selftests/pipe: add pipe_bench microbenchmark fs/pipe: pre-allocate pages outside pipe->mutex in anon_pipe_write fs: retire stale comment in fget_task_next() fs: fix spelling mistakes in comment bfs: replace get_zeroed_page() with kzalloc() binfmt_misc: replace __get_free_page() with kmalloc() configfs: replace __get_free_pages() with kzalloc() fs/namespace: use __getname() to allocate mntpath buffer fs/select: replace __get_free_page() with kmalloc() ...	2026-06-15 03:59:45 +05:30

To get an operable file descriptor from an O_PATH file descriptor it is possible to use openat(fd, ".", O_DIRECTORY) for directories, but other file types require going through open("/proc/<pid>/fd/<nr>") and thus depend on a functioning procfs. With O_EMPTYPATH an empty path string is accepted and LOOKUP_EMPTY is set at path resolution time, allowing to reopen the file behind the file descriptor directly. Selftests are included. - Add an OPENAT2_REGULAR flag for openat2(2) which refuses to open anything but regular files with the new EFTYPE error code. This implements the "ability to only open regular files" feature requested by userspace via uapi-group.org and protects services from being redirected to fifos, device nodes, and friends. All atomic_open implementations were audited for OPENAT2_REGULAR handling. Explicit checks were added to ceph, gfs2, nfs (v4), and cifs/smb - these are the filesystems whose atomic_open can encounter an existing non-regular file and would otherwise call finish_open() on it or return a misleading error code. The remaining implementations (9p, fuse, vboxsf, nfs v2/v3) only call finish_open() on freshly created files and use finish_no_open() for lookup hits, letting the VFS catch non-regular files via the do_open() safety net. Cleanups: - Migrate the openat2 selftests to the kselftest harness and move them under selftests/filesystems/. The tests were written in the early days of selftests' TAP support and the modern kselftest harness is much easier to follow and maintain. The contents of the tests are unchanged and the new emptypath tests are ported on top. - Make the LAST_XXX last-type constants private to fs/namei.c. The only user outside of fs/namei.c was ksmbd which only needs to know whether the last component is a regular one, so vfs_path_parent_lookup() now performs the LAST_NORM check internally.

It stays attached to the task for its full lifetime. __ptrace_may_access() and several /proc owner and visibility checks need to consult two pieces of state for any observable task, including zombies that have already gone through exit_mm(): the dumpable mode and the user namespace captured at execve(). Both live on mm_struct today, which exit_mm() clears from the task long before the task is reaped. A reader that races with do_exit() observes task->mm == NULL and either fails the check or falls back to init_user_ns - which denies legitimate access to non-dumpable zombies that were running in a nested user namespace. mm_struct loses ->user_ns and the dumpability bits in ->flags. MMF_DUMPABLE_BITS is reserved so the MMF_DUMP_FILTER_* layout exposed via /proc/<pid>/coredump_filter stays stable. task->user_dumpable and its exit_mm() snapshot are removed. task_exec_state is the privilege domain established by an execve(). Within a thread group it is shared via refcount; across thread groups each task has its own: - CLONE_VM siblings (thread-group members, io_uring workers) refcount-share the parent's exec_state. - Non-CLONE_VM clones (fork(), vfork() without CLONE_VM) allocate a fresh exec_state inheriting the parent's dumpable mode and user_ns. - execve() in the child allocates a fresh instance and installs it under task_lock + exec_update_lock via task_exec_state_replace(). - Credential changes (setresuid, capset, ...) and prctl(PR_SET_DUMPABLE) update dumpability on the current task's exec_state, i.e., on the thread group's shared instance. On top of this exec_mmap() no longer tears down the old mm while holding exec_update_lock for writing and cred_guard_mutex. Neither lock is needed for that: exec_update_lock only exists to make the mm swap atomic with the later commit_creds() and all its readers operate on the new mm; none looks at the detached old mm. The cost was real: __mmput() runs exit_mmap() over the entire old address space and can block in exit_aio() waiting for in-flight AIO, so execve() of a large process blocked ptrace_attach() and every exec_update_lock reader for the duration of the teardown. The old mm is now stashed in bprm->old_mm and released from setup_new_exec() after both locks are dropped, with a backstop in free_bprm() for the error paths" * tag 'kernel-7.2-rc1.task_exec_state' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: exec: free the old mm outside the exec locks exec_state: relocate dumpable information ptrace: add ptracer_access_allowed() exec: introduce struct task_exec_state sched/coredump: introduce enum task_dumpable	2026-06-15 03:00:58 +05:30

This avoids the lock for the common cases of nfs calling into the inode hash and btrfs using igrab(). Cleanup-wise icount_read_once() is added to line up with inode_state_read_once() and the open-coded ->i_count loads across the tree are converted, and ihold() is relocated and tidied up.
