git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking changes from Jakub Kicinski: "WiFi 7 and sendpage changes are the biggest pieces of work for this release. The latter will definitely require fixes but I think that we got it to a reasonable point. Core: - Rework the sendpage & splice implementations Instead of feeding data into sockets page by page extend sendmsg handlers to support taking a reference on the data, controlled by a new flag called MSG_SPLICE_PAGES Rework the handling of unexpected-end-of-file to invoke an additional callback instead of trying to predict what the right combination of MORE/NOTLAST flags is Remove the MSG_SENDPAGE_NOTLAST flag completely - Implement SCM_PIDFD, a new type of CMSG type analogous to SCM_CREDENTIALS, but it contains pidfd instead of plain pid - Enable socket busy polling with CONFIG_RT - Improve reliability and efficiency of reporting for ref_tracker - Auto-generate a user space C library for various Netlink families Protocols: - Allow TCP to shrink the advertised window when necessary, prevent sk_rcvbuf auto-tuning from growing the window all the way up to tcp_rmem[2] - Use per-VMA locking for "page-flipping" TCP receive zerocopy - Prepare TCP for device-to-device data transfers, by making sure that payloads are always attached to skbs as page frags - Make the backoff time for the first N TCP SYN retransmissions linear. Exponential backoff is unnecessarily conservative - Create a new MPTCP getsockopt to retrieve all info (MPTCP_FULL_INFO) - Avoid waking up applications using TLS sockets until we have a full record - Allow using kernel memory for protocol ioctl callbacks, paving the way to issuing ioctls over io_uring - Add nolocalbypass option to VxLAN, forcing packets to be fully encapsulated even if they are destined for a local IP address - Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure in-kernel ECMP implementation (e.g. Open vSwitch) select the same link for all packets. Support L4 symmetric hashing in Open vSwitch - PPPoE: make number of hash bits configurable - Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client (ipconfig) - Add layer 2 miss indication and filtering, allowing higher layers (e.g. ACL filters) to make forwarding decisions based on whether packet matched forwarding state in lower devices (bridge) - Support matching on Connectivity Fault Management (CFM) packets - Hide the "link becomes ready" IPv6 messages by demoting their printk level to debug - HSR: don't enable promiscuous mode if device offloads the proto - Support active scanning in IEEE 802.15.4 - Continue work on Multi-Link Operation for WiFi 7 BPF: - Add precision propagation for subprogs and callbacks. This allows maintaining verification efficiency when subprograms are used, or in fact passing the verifier at all for complex programs, especially those using open-coded iterators - Improve BPF's {g,s}setsockopt() length handling. Previously BPF assumed the length is always equal to the amount of written data. But some protos allow passing a NULL buffer to discover what the output buffer *should* be, without writing anything - Accept dynptr memory as memory arguments passed to helpers - Add routing table ID to bpf_fib_lookup BPF helper - Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands - Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark maps as read-only) - Show target_{obj,btf}_id in tracing link fdinfo - Addition of several new kfuncs (most of the names are self-explanatory): - Add a set of new dynptr kfuncs: bpf_dynptr_adjust(), bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size() and bpf_dynptr_clone(). - bpf_task_under_cgroup() - bpf_sock_destroy() - force closing sockets - bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs Netfilter: - Relax set/map validation checks in nf_tables. Allow checking presence of an entry in a map without using the value - Increase ip_vs_conn_tab_bits range for 64BIT builds - Allow updating size of a set - Improve NAT tuple selection when connection is closing Driver API: - Integrate netdev with LED subsystem, to allow configuring HW "offloaded" blinking of LEDs based on link state and activity (i.e. packets coming in and out) - Support configuring rate selection pins of SFP modules - Factor Clause 73 auto-negotiation code out of the drivers, provide common helper routines - Add more fool-proof helpers for managing lifetime of MDIO devices associated with the PCS layer - Allow drivers to report advanced statistics related to Time Aware scheduler offload (taprio) - Allow opting out of VF statistics in link dump, to allow more VFs to fit into the message - Split devlink instance and devlink port operations New hardware / drivers: - Ethernet: - Synopsys EMAC4 IP support (stmmac) - Marvell 88E6361 8 port (5x1GE + 3x2.5GE) switches - Marvell 88E6250 7 port switches - Microchip LAN8650/1 Rev.B0 PHYs - MediaTek MT7981/MT7988 built-in 1GE PHY driver - WiFi: - Realtek RTL8192FU, 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps - Realtek RTL8723DS (SDIO variant) - Realtek RTL8851BE - CAN: - Fintek F81604 Drivers: - Ethernet NICs: - Intel (100G, ice): - support dynamic interrupt allocation - use meta data match instead of VF MAC addr on slow-path - nVidia/Mellanox: - extend link aggregation to handle 4, rather than just 2 ports - spawn sub-functions without any features by default - OcteonTX2: - support HTB (Tx scheduling/QoS) offload - make RSS hash generation configurable - support selecting Rx queue using TC filters - Wangxun (ngbe/txgbe): - add basic Tx/Rx packet offloads - add phylink support (SFP/PCS control) - Freescale/NXP (enetc): - report TAPRIO packet statistics - Solarflare/AMD: - support matching on IP ToS and UDP source port of outer header - VxLAN and GENEVE tunnel encapsulation over IPv4 or IPv6 - add devlink dev info support for EF10 - Virtual NICs: - Microsoft vNIC: - size the Rx indirection table based on requested configuration - support VLAN tagging - Amazon vNIC: - try to reuse Rx buffers if not fully consumed, useful for ARM servers running with 16kB pages - Google vNIC: - support TCP segmentation of >64kB frames - Ethernet embedded switches: - Marvell (mv88e6xxx): - enable USXGMII (88E6191X) - Microchip: - lan966x: add support for Egress Stage 0 ACL engine - lan966x: support mapping packet priority to internal switch priority (based on PCP or DSCP) - Ethernet PHYs: - Broadcom PHYs: - support for Wake-on-LAN for BCM54210E/B50212E - report LPI counter - Microsemi PHYs: support RGMII delay configuration (VSC85xx) - Micrel PHYs: receive timestamp in the frame (LAN8841) - Realtek PHYs: support optional external PHY clock - Altera TSE PCS: merge the driver into Lynx PCS which it is a variant of - CAN: Kvaser PCIEcan: - support packet timestamping - WiFi: - Intel (iwlwifi): - major update for new firmware and Multi-Link Operation (MLO) - configuration rework to drop test devices and split the different families - support for segmented PNVM images and power tables - new vendor entries for PPAG (platform antenna gain) feature - Qualcomm 802.11ax (ath11k): - Multiple Basic Service Set Identifier (MBSSID) and Enhanced MBSSID Advertisement (EMA) support in AP mode - support factory test mode - RealTek (rtw89): - add RSSI based antenna diversity - support U-NII-4 channels on 5 GHz band - RealTek (rtl8xxxu): - AP mode support for 8188f - support USB RX aggregation for the newer chips" * tag 'net-next-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1602 commits) net: scm: introduce and use scm_recv_unix helper af_unix: Skip SCM_PIDFD if scm->pid is NULL. net: lan743x: Simplify comparison netlink: Add __sock_i_ino() for __netlink_diag_dump(). net: dsa: avoid suspicious RCU usage for synced VLAN-aware MAC addresses Revert "af_unix: Call scm_recv() only after scm_set_cred()." phylink: ReST-ify the phylink_pcs_neg_mode() kdoc libceph: Partially revert changes to support MSG_SPLICE_PAGES net: phy: mscc: fix packet loss due to RGMII delays net: mana: use vmalloc_array and vcalloc net: enetc: use vmalloc_array and vcalloc ionic: use vmalloc_array and vcalloc pds_core: use vmalloc_array and vcalloc gve: use vmalloc_array and vcalloc octeon_ep: use vmalloc_array and vcalloc net: usb: qmi_wwan: add u-blox 0x1312 composition perf trace: fix MSG_SPLICE_PAGES build error ipvlan: Fix return value of ipvlan_queue_xmit() netfilter: nf_tables: fix underflow in chain reference counter netfilter: nf_tables: unbind non-anonymous set if rule construction fails ...

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull hardening updates from Kees Cook: "There are three areas of note: A bunch of strlcpy()->strscpy() conversions ended up living in my tree since they were either Acked by maintainers for me to carry, or got ignored for multiple weeks (and were trivial changes). The compiler option '-fstrict-flex-arrays=3' has been enabled globally, and has been in -next for the entire devel cycle. This changes compiler diagnostics (though mainly just -Warray-bounds which is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_ coverage. In other words, there are no new restrictions, just potentially new warnings. Any new FORTIFY warnings we've seen have been fixed (usually in their respective subsystem trees). For more details, see commit df8fc4e934c12b. The under-development compiler attribute __counted_by has been added so that we can start annotating flexible array members with their associated structure member that tracks the count of flexible array elements at run-time. It is possible (likely?) that the exact syntax of the attribute will change before it is finalized, but GCC and Clang are working together to sort it out. Any changes can be made to the macro while we continue to add annotations. As an example of that last case, I have a treewide commit waiting with such annotations found via Coccinelle: https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b Also see commit dd06e72e68bcb4 for more details. Summary: - Fix KMSAN vs FORTIFY in strlcpy/strlcat (Alexander Potapenko) - Convert strreplace() to return string start (Andy Shevchenko) - Flexible array conversions (Arnd Bergmann, Wyes Karny, Kees Cook) - Add missing function prototypes seen with W=1 (Arnd Bergmann) - Fix strscpy() kerndoc typo (Arne Welzel) - Replace strlcpy() with strscpy() across many subsystems which were either Acked by respective maintainers or were trivial changes that went ignored for multiple weeks (Azeem Shaikh) - Remove unneeded cc-option test for UBSAN_TRAP (Nick Desaulniers) - Add KUnit tests for strcat()-family - Enable KUnit tests of FORTIFY wrappers under UML - Add more complete FORTIFY protections for strlcat() - Add missed disabling of FORTIFY for all arch purgatories. - Enable -fstrict-flex-arrays=3 globally - Tightening UBSAN_BOUNDS when using GCC - Improve checkpatch to check for strcpy, strncpy, and fake flex arrays - Improve use of const variables in FORTIFY - Add requested struct_size_t() helper for types not pointers - Add __counted_by macro for annotating flexible array size members" * tag 'hardening-v6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: (54 commits) netfilter: ipset: Replace strlcpy with strscpy uml: Replace strlcpy with strscpy um: Use HOST_DIR for mrproper kallsyms: Replace all non-returning strlcpy with strscpy sh: Replace all non-returning strlcpy with strscpy of/flattree: Replace all non-returning strlcpy with strscpy sparc64: Replace all non-returning strlcpy with strscpy Hexagon: Replace all non-returning strlcpy with strscpy kobject: Use return value of strreplace() lib/string_helpers: Change returned value of the strreplace() jbd2: Avoid printing outside the boundary of the buffer checkpatch: Check for 0-length and 1-element arrays riscv/purgatory: Do not use fortified string functions s390/purgatory: Do not use fortified string functions x86/purgatory: Do not use fortified string functions acpi: Replace struct acpi_table_slit 1-element array with flex-array clocksource: Replace all non-returning strlcpy with strscpy string: use __builtin_memcpy() in strlcpy/strlcat staging: most: Replace all non-returning strlcpy with strscpy drm/i2c: tda998x: Replace all non-returning strlcpy with strscpy ...

git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull ordered workqueue creation updates from Tejun Heo: "For historical reasons, unbound workqueues with max concurrency limit of 1 are considered ordered, even though the concurrency limit hasn't been system-wide for a long time. This creates ambiguity around whether ordered execution is actually required for correctness, which was actually confusing for e.g. btrfs (btrfs updates are being routed through the btrfs tree). There aren't that many users in the tree which use the combination and there are pending improvements to unbound workqueue affinity handling which will make inadvertent use of ordered workqueue a bigger loss. This clarifies the situation for most of them by updating the ones which require ordered execution to use alloc_ordered_workqueue(). There are some conversions being routed through subsystem-specific trees and likely a few stragglers. Once they're all converted, workqueue can trigger a warning on unbound + @max_active==1 usages and eventually drop the implicit ordered behavior" * tag 'wq-for-6.5-cleanup-ordered' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: rxrpc: Use alloc_ordered_workqueue() to create ordered workqueues net: qrtr: Use alloc_ordered_workqueue() to create ordered workqueues net: wwan: t7xx: Use alloc_ordered_workqueue() to create ordered workqueues dm integrity: Use alloc_ordered_workqueue() to create ordered workqueues media: amphion: Use alloc_ordered_workqueue() to create ordered workqueues scsi: NCR5380: Use default @max_active for hostdata->work_q media: coda: Use alloc_ordered_workqueue() to create ordered workqueues crypto: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues wifi: ath10/11/12k: Use alloc_ordered_workqueue() to create ordered workqueues wifi: mwifiex: Use default @max_active for workqueues wifi: iwlwifi: Use default @max_active for trans_pcie->rba.alloc_wq xen/pvcalls: Use alloc_ordered_workqueue() to create ordered workqueues virt: acrn: Use alloc_ordered_workqueue() to create ordered workqueues net: octeontx2: Use alloc_ordered_workqueue() to create ordered workqueues net: thunderx: Use alloc_ordered_workqueue() to create ordered workqueues greybus: Use alloc_ordered_workqueue() to create ordered workqueues powerpc, workqueue: Use alloc_ordered_workqueue() to create ordered workqueues

The thermal framework is migrating to the generic trip points. The set of changes also implies a self-encapsulation of the thermal zone device structure where the internals are no longer directly accessible but with accessors. Use the new API instead, so the next changes can be pushed in the thermal framework without this driver failing to compile. No functional changes intended.

64-bit DMA detection will fail if axienet was started before (by boot loader, boot ROM, etc). In this state axienet will not start properly. XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect 64-bit DMA capability here. But datasheet says: When DMACR.RS is 1 (axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and is used to fetch the first descriptor. So iowrite32()/ioread32() trick to this register to detect 64-bit DMA will not work. So move axienet reset before 64-bit DMA detection.

2023-06-23mlxsw: spectrum_router: Track next hops at CRIFsPetr Machata1-52/+75
Move the list of next hops from struct mlxsw_sp_rif to mlxsw_sp_crif. The reason is that eventually, next hops for mlxsw uppers should be offloaded and unoffloaded on demand as a netdevice becomes an upper, or stops being one. Currently, next hops are tracked at RIFs, but RIFs do not exist when a netdevice is not an mlxsw uppers. CRIFs are kept track of throughout the netdevice lifetime. Correspondingly, track at each next hop not its RIF, but its CRIF (from which a RIF can always be deduced). Note that now that next hops are tracked at a CRIF, it is not necessary to move each over to a new RIF when it is necessary to edit a RIF. Therefore drop mlxsw_sp_nexthop_rif_migrate() and have mlxsw_sp_rif_migrate_destroy() call mlxsw_sp_nexthop_rif_update() directly.

2023-06-23mlxsw: spectrum_router: Split nexthop finalization to two stagesPetr Machata1-4/+9
Nexthop finalization consists of two steps: the part where the offload is removed, because the backing RIF is now gone; and the part where the association to the RIF is severed. Extract from mlxsw_sp_nexthop_type_fini() a helper that covers the unoffloading part, mlxsw_sp_nexthop_type_rif_gone(), so that it can later be called independently. Note that this swaps around the ordering of mlxsw_sp_nexthop_ipip_fini() vs. mlxsw_sp_nexthop_rif_fini(). The current ordering is more of a historical happenstance than a conscious decision. The two cleanups do not depend on each other, and this change should have no observable effects.

2023-06-23mlxsw: spectrum_router: Link CRIFs to RIFsPetr Machata1-12/+47
When a RIF is about to be created, the registration of the netdevice that it should be associated with must have been seen in the past, and a CRIF created. Therefore make this a hard requirement by looking up the CRIF during RIF creation, and complaining loudly when there isn't one. This then allows to keep a link between a RIF and its corresponding CRIF (and back, as the relationship is one-to-at-most-one), which do. The CRIF will later be useful as the objects tracked there will be offloaded lazily as a result of RIF creation. CRIFs are created when an "interesting" netdevice is registered, and destroyed after such device is unregistered. CRIFs are supposed to already exist when a RIF creation request arises, and exist at least as long as that RIF exists. This makes for a simple invariant: it is always safe to dereference CRIF pointer from "its" RIF. To guarantee this, CRIFs cannot be removed immediately when the UNREGISTER event is delivered. The reason is that if a RIF's netdevices has an IPv6 address, removal of this address is notified in an atomic block. To remove the RIF, the IPv6 removal handler schedules a work item. It must be safe for this work item to access the associated CRIF as well. Thus when a netdevice that backs the CRIF is removed, if it still has a RIF, do not actually free the CRIF, only toggle its can_destroy flag, which this patch adds. Later on, mlxsw_sp_rif_destroy() collects the CRIF.

2023-06-23mlxsw: spectrum_router: Maintain CRIF for fallback loopback RIFPetr Machata2-1/+12
CRIFs are generally not maintained for loopback RIFs. However, the RIF for the default VRF is used for offloading of blackhole nexthops. Nexthops expect to have a valid CRIF. Therefore in this patch, add code to maintain CRIF for the loopback RIF as well.

2023-06-23mlxsw: spectrum_router: Maintain a hash table of CRIFsPetr Machata2-0/+176
CRIFs are objects that mlxsw maintains for netdevices that may not have an associated RIF (i.e. they may not have been instantiated in the ASIC), but if indeed they do not, it is quite possible they will in the future. These netdevices are candidate RIFs, hence CRIFs. Netdevices for which CRIFs are created include e.g. bridges, LAGs, or front panel ports. The idea is that next hops would be kept at CRIFs, not RIFs, and thus it would be easier to offload and unoffload the entities that have been added before the RIF was created. In this patch, add the code for low-level CRIF maintenance: create and destroy, and keep in a table keyed by the netdevice pointer for easy recall.

2023-06-23mlxsw: spectrum_router: Use mlxsw_sp_ul_rif_get() to get main VRF LB RIFPetr Machata1-5/+6
The current function, mlxsw_sp_router_ul_rif_get(), is a wrapper around the function mentioned in the subject. As such it forms an external interface of the router code. In future patches we will want to maintain connection between RIFs and the CRIFs (introduced in the next patch) that back them. That will not hold for the VRF-based loopback netdevices, so the whole CRIF business can be kept hidden from the rest of mlxsw. But for the main VRF loopback RIF we do want to keep the RIF-CRIF connection, because that RIF is used for blackhole next hops, and the next hop code can be kept simpler for assuming rif->crif is valid. Hence, instead, call mlxsw_sp_ul_rif_get() to create the main VRF loopback RIF. This being an internal function will take the CRIF argument anyway. Furthermore, the function does not lock, which is not necessary at this point in code yet.

With support for Ethernet PHY LEDs having been added, while unregistering a MDIO bus and its child device liks PHYs there may be "late" accesses to the MDIO bus. One typical use case is setting the PHY LEDs brightness to OFF for instance. We need to ensure that the MDIO bus controller remains entirely functional since it runs off the main GENET adapter clock.
