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

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.

All callers of tls_is_sk_tx_device_offloaded() currently do an equivalent of:

Have the helper accept skb and do the skb->sk check locally. Two drivers have local static inlines with similar wrappers already.
While at it change the ifdef condition to TLS_DEVICE. Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are equivalent. This makes removing the duplicated IS_ENABLED() check in funeth more obviously correct.

Merge branch 'splice-net-rewrite-splice-to-socket-fix-splice_f_more-and-handle-msg_splice_pages-in-af_tls'
David Howells says:
==================== splice, net: Rewrite splice-to-socket, fix SPLICE_F_MORE and handle MSG_SPLICE_PAGES in AF_TLS
Here are patches to do the following:
(1) Block MSG_SENDPAGE_* flags from leaking into ->sendmsg() from userspace, whilst allowing splice_to_socket() to pass them in.
(2) Allow MSG_SPLICE_PAGES to be passed into tls_*_sendmsg(). Until support is added, it will be ignored and a splice-driven sendmsg() will be treated like a normal sendmsg(). TCP, UDP, AF_UNIX and Chelsio-TLS already handle the flag in net-next.
(3) Replace a chain of functions to splice-to-sendpage with a single function to splice via sendmsg() with MSG_SPLICE_PAGES. This allows a bunch of pages to be spliced from a pipe in a single call using a bio_vec[] and pushes the main processing loop down into the bowels of the protocol driver rather than repeatedly calling in with a page at a time.
(4) Provide a ->splice_eof() op[2] that allows splice to signal to its output that the input observed a premature EOF and that the caller didn't flag SPLICE_F_MORE, thereby allowing a corked socket to be flushed. This attempts to maintain the current behaviour. It is also not called if we didn't manage to read any data and so didn't called the actor function.
This needs routing though several layers to get it down to the network protocol.
[!] Note that I chose not to pass in any flags - I'm not sure it's particularly useful to pass in the splice flags; I also elected not to return any error code - though we might actually want to do that.
(5) Provide tls_{device,sw}_splice_eof() to flush a pending TLS record if there is one.
(6) Provide splice_eof() for UDP, TCP, Chelsio-TLS and AF_KCM. AF_UNIX doesn't seem to pay attention to the MSG_MORE or MSG_SENDPAGE_NOTLAST flags.
(7) Alter the behaviour of sendfile() and fix SPLICE_F_MORE/MSG_MORE signalling[1] such SPLICE_F_MORE is always signalled until we have read sufficient data to finish the request. If we get a zero-length before we've managed to splice sufficient data, we now leave the socket expecting more data and leave it to userspace to deal with it.
(8) Make AF_TLS handle the MSG_SPLICE_PAGES internal sendmsg flag. MSG_SPLICE_PAGES is an internal hint that tells the protocol that it should splice the pages supplied if it can. Its sendpage implementations are then turned into wrappers around that.

tls/device: Convert tls_device_sendpage() to use MSG_SPLICE_PAGES
Convert tls_device_sendpage() to use sendmsg() with MSG_SPLICE_PAGES rather than directly splicing in the pages itself. With that, the tls_iter_offset union is no longer necessary and can be replaced with an iov_iter pointer and the zc_page argument to tls_push_data() can also be removed.
This allows ->sendpage() to be replaced by something that can handle multiple multipage folios in a single transaction.

spi-geni-qcom: Add new interfaces and utilise them
Merge series from Vijaya Krishna Nivarthi <quic_vnivarth@quicinc.com>:
A "known issue" during implementation of SE DMA for spi geni driver was that it does DMA map/unmap internally instead of in spi framework. Current patches remove this hiccup and also clean up code a bit.
Testing revealed no regressions and results with 1000 iterations of reading from EC showed no loss of performance. Results ======= Before - Iteration 999, min=5.10, max=5.17, avg=5.14, ints=25129 After - Iteration 999, min=5.10, max=5.20, avg=5.15, ints=25153
