Merge tag 'net-next-6.5' of 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

Merge tag 'arm-vfp-refactor-for-rmk' of git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux into devel-stable
Refactor VFP support code and reimplement in C
The VFP related changes to permit kernel mode NEON in softirq context resulted in some issues regarding en/disabling of sofirqs from asm code, and this made it clear that it would be better to handle more of it from C code.
Given that we already have infrastructure that associates undefined instruction exceptions with handler code based on value/mask pairs, we can easily move the dispatch of VFP and NEON instructions to C code once we reimplement the actual VFP support routine (which reasons about how to deal with the exception and whether any emulation is needed) in C code first.
With those out of the way, we can drop the partial decoding logic in asm that reasons about which ISA is being used by user space, as the remaining cases are all 32-bit ARM only. This leaves a FPE specific routine with some iWMMXT logic that is easily duplicated in C as well, allowing us to move the FPE asm code into the FPE asm source file, and out of the shared entry code.

Merge branch 'splice-net-switch-over-users-of-sendpage-and-remove-it'
David Howells says:
==================== splice, net: Switch over users of sendpage() and remove it
Here's the final set of patches towards the removal of sendpage. All the drivers that use sendpage() get switched over to using sendmsg() with MSG_SPLICE_PAGES.
The following changes are made:
(1) Make the protocol drivers behave according to MSG_MORE, not MSG_SENDPAGE_NOTLAST. The latter is restricted to turning on MSG_MORE in the sendpage() wrappers.
(2) Fix ocfs2 to allocate its global protocol buffers with folio_alloc() rather than kzalloc() so as not to invoke the !sendpage_ok warning in skb_splice_from_iter().
(3) Make ceph/rds, skb_send_sock, dlm, nvme, smc, ocfs2, drbd and iscsi use sendmsg(), not sendpage and make them specify MSG_MORE instead of MSG_SENDPAGE_NOTLAST.
(4) Kill off sendpage and clean up MSG_SENDPAGE_NOTLAST.

netlink: support extack in dump ->start()
Commit 4a19edb60d02 ("netlink: Pass extack to dump handlers") added extack support to netlink dumps. It was focused on rtnl and since rtnl does not use ->start(), ->done() callbacks it ignored those. Genetlink on the other hand uses ->start() extensively, for parsing and input validation.
Pass the extact in via struct netlink_dump_control and link it to cb for the time of ->start(). Both struct netlink_dump_control and extack itself live on the stack so we can't keep the same extack for the duration of the dump. This means that the extack visible in ->start() and each ->dump() callbacks will be different. Corner cases like reporting a warning message in DONE across dump calls are still not supported.
We could put the extack (for dumps) in the socket struct, but layering makes it slightly awkward (extack pointer is decided before the DO / DUMP split).
The genetlink dump error extacks are now surfaced:
$ cli.py --spec netlink/specs/ethtool.yaml --dump channels-get lib.ynl.NlError: Netlink error: Invalid argument nl_len = 64 (48) nl_flags = 0x300 nl_type = 2 error: -22 extack: {'msg': 'request header missing'}
Previously extack was missing:
