"This adds support for IORING_CQE_F_SOCK_NONEMPTY for io_uring accept
requests.

This is very similar to previous work that enabled the same hint for
doing receives on sockets. By far the majority of the work here is
refactoring to enable the networking side to pass back whether or not
the socket had more pending requests after accepting the current one,
the last patch just wires it up for io_uring.

Not only does this enable applications to know whether there are more
connections to accept right now, it also enables smarter logic for
io_uring multishot accept on whether to retry immediately or wait for
a poll trigger"

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.

ocfs2: Fix use of slab data with sendpage

ocfs2 uses kzalloc() to allocate buffers for o2net_hand, o2net_keep_req and
o2net_keep_resp and then passes these to sendpage. This isn't really
allowed as the lifetime of slab objects is not controlled by page ref -
though in this case it will probably work. sendmsg() with MSG_SPLICE_PAGES
will, however, print a warning and give an error.

Fix it to use folio_alloc() instead to allocate a buffer for the handshake
message, keepalive request and reply messages.
