As noted by Cong Wang, the splat is false positive, but the code
path leading to the report is an unexpected one: a client is
attempting an MPC handshake towards the in-kernel listener created
by the in-kernel PM for a port based signal endpoint.

Such connection will be never accepted; many of them can make the
listener queue full and preventing the creation of MPJ subflow via
such listener - its intended role.

Explicitly detect this scenario at initial-syn time and drop the
incoming MPC request.

Bugged peer implementation can send corrupted DSS options, consistently

avoid the splat on some builds and handle consistently the error, dumping
related MIBs and performing fallback and/or reset according to the
subflow type.

mptcp: mib: count MPJ with backup flag

commit 4dde0d72ccec500c60c798e036b852e013d6e124 upstream.

Without such counters, it is difficult to easily debug issues with MPJ
not having the backup flags on production servers.

This is not strictly a fix, but it eases to validate the following
patches without requiring to take packet traces, to query ongoing
connections with Netlink with admin permissions, or to guess by looking
at the behaviour of the packet scheduler. Also, the modification is self
contained, isolated, well controlled, and the increments are done just
after others, there from the beginning. It looks then safe, and helpful
to backport this.

mptcp: add CurrEstab MIB counter support

[ Upstream commit d9cd27b8cd191133e287e5de107f971136abe8a2 ]

Add a new MIB counter named MPTCP_MIB_CURRESTAB to count current
established MPTCP connections, similar to TCP_MIB_CURRESTAB. This is
useful to quickly list the number of MPTCP connections without having to
iterate over all of them.

This patch adds a new helper function mptcp_set_state(): if the state
switches from or to ESTABLISHED state, this newly added counter is
incremented. This helper is going to be used in the following patch.

Similar to MPTCP_INC_STATS(), a new helper called MPTCP_DEC_STATS() is
also needed to decrement a MIB counter.

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

Merge branch 'mptcp-refactor-inet_accept-and-mib-updates'

Mat Martineau says:

====================
mptcp: Refactor inet_accept() and MIB updates

Patches 1 and 2 refactor inet_accept() to provide a new __inet_accept()
that's usable with locked sockets, and then make use of that helper to
simplify mptcp_stream_accept().

Patches 3 and 4 add some new MIBS related to MPTCP address advertisement
and update related selftest scripts.

Patch 5 modifies the selftests to ensure MIBS are only printed once when
a test case fails.

mptcp: introduces more address related mibs

Currently we don't track explicitly a few events related to address
management suboption handling; this patch adds new mibs for ADD_ADDR
and RM_ADDR options tx and for missed tx events due to internal storage
exhaustion.

The self-tests must be updated to properly handle different mibs with
the same/shared prefix.

Additionally removes a couple of warning tracking the loss event.
