Merge tag 'net-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"The zero-copy changes are relatively significant, but regression risk
should be contained. The feature needs to be used to cause trouble.

Also it feels like we got an order of magnitude more semi-automated
"refactoring" chaff than usual, I wonder if it's just us.

Core & protocols:

- Support Device Memory TCP, ability to zero-copy receive TCP
payloads to a DMABUF region of memory while packet headers land
separately in normal kernel buffers, and TCP processes then as
usual.

- The ability to read the PTP PHC (Physical Hardware Clock) alongside
MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
only CLOCK_REALTIME was supported.

- Allow matching on all bits of IP DSCP for routing decisions.
Previously we only supported on matching TOS bits in IPv4 which is
a narrower interpretation of the same header field.

- Increase the range of weights used for multi-path routing from
8 bits to 16 bits.

- Add support for IPv6 PIO p flag in the Prefix Information Option
per draft-ietf-6man-pio-pflag.

- IPv6 IOAM6 support for new tunsrc encap mode for better
performance.

- Detect destinations which blackhole MPTCP traffic and avoid
initiating MPTCP connections to them for a certain period of time,
1h by default.

- Improve IPsec control path performance by removing the inexact
policies list.

- AF_VSOCK: add support for SIOCOUTQ ioctl.

- Add enum for reasons TCP reset was sent for easier tracing.

- Add SMC ringbufs usage statistics.

Drivers:

- Handle netconsole setup failures more gracefully, don't fail
loading, retain the specified target as disabled.

- Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

Filtering:

- Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
when long-lived sockets miss a chance to set additional callbacks
if a sockops program was not attached early in their lifetime.

- Support using BPF skb helpers in tracepoints.

- Conntrack Netlink: support CTA_FILTER for flush.

- Improve SCTP support in nfnetlink_queue.

- Improve performance of large nftables flush transactions.

Things we sprinkled into general kernel code:

- selftests: support setting an "interpreter" for script files; make
it easy to run as separate cases tests where one "interpreter" is
fed various test descriptions (in our case packet sequences).

Driver API:

- Extend core and ethtool APIs to support many PHYs connected to a
single interface (PHY topologies).

- Extend cable diagnostics to specify whether Time Domain
Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
used.

- Add library for implementing MAC-PHY Ethernet drivers for SPI
devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
Interface (TC6) standard.

- Add helpers to the PHY framework, for PHYs following the Open
Alliance standards:
- 1000BaseT1 link settings
- cable test and diagnostics

- Support listing / dumping all allocated RSS contexts.

- Add configuration for frequency Embedded SYNC in DPLL, which
magically embeds sync pulses into Ethernet signaling.

Merge branch 'tc-adjust-network-header-after-2nd-vlan-push'

Boris Sukholitko says:

====================
tc: adjust network header after 2nd vlan push

<tldr>
skb network header of the single-tagged vlan packet continues to point the
vlan payload (e.g. IP) after second vlan tag is pushed by tc act_vlan. This
causes problem at the dissector which expects double-tagged packet network
header to point to the inner vlan.

The fix is to adjust network header in tcf_act_vlan.c but requires
refactoring of skb_vlan_push function.
</tldr>

Consider the following shell script snippet configuring TC rules on the
veth interface:

ip link add veth0 type veth peer veth1
ip link set veth0 up
ip link set veth1 up

tc qdisc add dev veth0 clsact

tc filter add dev veth0 ingress pref 10 chain 0 flower \
num_of_vlans 2 cvlan_ethtype 0x800 action goto chain 5
tc filter add dev veth0 ingress pref 20 chain 0 flower \
num_of_vlans 1 action vlan push id 100 \
protocol 0x8100 action goto chain 5
tc filter add dev veth0 ingress pref 30 chain 5 flower \
num_of_vlans 2 cvlan_ethtype 0x800 action simple sdata "success"

Sending double-tagged vlan packet with the IP payload inside:

cat <<ENDS | text2pcap - - | tcpreplay -i veth1 -
0000 00 00 00 00 00 11 00 00 00 00 00 22 81 00 00 64 ..........."...d

ENDS

will match rule 10, goto rule 30 in chain 5 and correctly emit "success" to
the dmesg.

OTOH, sending single-tagged vlan packet:

cat <<ENDS | text2pcap - - | tcpreplay -i veth1 -
0000 00 00 00 00 00 11 00 00 00 00 00 22 81 00 00 14 ..........."....

0030 00 00 00 00 00 00 00 00 00 00 00 00 ............
ENDS

will match rule 20, will push the second vlan tag but will *not* match
rule 30. IOW, the match at rule 30 fails if the second vlan was freshly
pushed by the kernel.

Lets look at __skb_flow_dissect working on the double-tagged vlan packet.
Here is the relevant code from around net/core/flow_dissector.c:1277
copy-pasted here for convenience:

if (dissector_vlan == FLOW_DISSECTOR_KEY_MAX &&
skb && skb_vlan_tag_present(skb)) {
proto = skb->protocol;
} else {
vlan = __skb_header_pointer(skb, nhoff, sizeof(_vlan),
data, hlen, &_vlan);
if (!vlan) {
fdret = FLOW_DISSECT_RET_OUT_BAD;
break;
}

proto = vlan->h_vlan_encapsulated_proto;
nhoff += sizeof(*vlan);
}

The "else" clause above gets the protocol of the encapsulated packet from
the skb data at the network header location. printk debugging has showed
that in the good double-tagged packet case proto is
htons(0x800 == ETH_P_IP) as expected. However in the single-tagged packet
case proto is garbage leading to the failure to match tc filter 30.

proto is being set from the skb header pointed by nhoff parameter which is
defined at the beginning of __skb_flow_dissect
(net/core/flow_dissector.c:1055 in the current version):

nhoff = skb_network_offset(skb);

Therefore the culprit seems to be that the skb network offset is different
between double-tagged packet received from the interface and single-tagged
packet having its vlan tag pushed by TC.

Lets look at the interesting points of the lifetime of the single/double
tagged packets as they traverse our packet flow.

Both of them will start at __netif_receive_skb_core where the first vlan
tag will be stripped:

if (eth_type_vlan(skb->protocol)) {
skb = skb_vlan_untag(skb);
if (unlikely(!skb))
goto out;
}

At this stage in double-tagged case skb->data points to the second vlan tag
while in single-tagged case skb->data points to the network (eg. IP)
header.

Looking at TC vlan push action (net/sched/act_vlan.c) we have the following
code at tcf_vlan_act (interesting points are in square brackets):

if (skb_at_tc_ingress(skb))
[1] skb_push_rcsum(skb, skb->mac_len);

....

case TCA_VLAN_ACT_PUSH:
err = skb_vlan_push(skb, p->tcfv_push_proto, p->tcfv_push_vid |
(p->tcfv_push_prio << VLAN_PRIO_SHIFT),
0);
if (err)
goto drop;
break;

....

out:
if (skb_at_tc_ingress(skb))
[3] skb_pull_rcsum(skb, skb->mac_len);

And skb_vlan_push (net/core/skbuff.c:6204) function does:

err = __vlan_insert_tag(skb, skb->vlan_proto,
skb_vlan_tag_get(skb));
if (err)
return err;

skb->protocol = skb->vlan_proto;
[2] skb->mac_len += VLAN_HLEN;

in the case of pushing the second tag. Lets look at what happens with
skb->data of the single-tagged packet at each of the above points:

1. As a result of the skb_push_rcsum, skb->data is moved back to the start
of the packet.

2. First VLAN tag is moved from the skb into packet buffer, skb->mac_len is
incremented, skb->data still points to the start of the packet.

3. As a result of the skb_pull_rcsum, skb->data is moved forward by the
modified skb->mac_len, thus pointing to the network header again.

Then __skb_flow_dissect will get confused by having double-tagged vlan
packet with the skb->data at the network header.

The solution for the bug is to preserve "skb->data at second vlan header"
semantics in the skb_vlan_push function. We do this by manipulating
skb->network_header rather than skb->mac_len. skb_vlan_push callers are
updated to do skb_reset_mac_len.

More about the patch series:

* patch 1 fixes skb_vlan_push and the callers
* patch 2 adds ingress tc_actions test
* patch 3 adds egress tc_actions test

ASoC: Fixes for v6.9

A relatively large set of fixes here, the biggest piece of it is a
series correcting some problems with the delay reporting for Intel SOF
cards but there's a bunch of other things. Everything here is driver
specific except for a fix in the core for an issue with sign extension
handling volume controls.

Merge tag 'net-next-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core & protocols:

- Large effort by Eric to lower rtnl_lock pressure and remove locks:

- Make commonly used parts of rtnetlink (address, route dumps
etc) lockless, protected by RCU instead of rtnl_lock.

- Add a netns exit callback which already holds rtnl_lock,
allowing netns exit to take rtnl_lock once in the core instead
of once for each driver / callback.

- Remove locks / serialization in the socket diag interface.

- Remove 6 calls to synchronize_rcu() while holding rtnl_lock.

- Remove the dev_base_lock, depend on RCU where necessary.

- Support busy polling on a per-epoll context basis. Poll length and
budget parameters can be set independently of system defaults.

- Introduce struct net_hotdata, to make sure read-mostly global
config variables fit in as few cache lines as possible.

- Add optional per-nexthop statistics to ease monitoring / debug of
ECMP imbalance problems.

- Support TCP_NOTSENT_LOWAT in MPTCP.

- Ensure that IPv6 temporary addresses' preferred lifetimes are long
enough, compared to other configured lifetimes, and at least 2 sec.

- Support forwarding of ICMP Error messages in IPSec, per RFC 4301.

- Add support for the independent control state machine for bonding
per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
control state machine.

- Add "network ID" to MCTP socket APIs to support hosts with multiple
disjoint MCTP networks.

- Re-use the mono_delivery_time skbuff bit for packets which user
space wants to be sent at a specified time. Maintain the timing
information while traversing veth links, bridge etc.

- Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.

- Simplify many places iterating over netdevs by using an xarray
instead of a hash table walk (hash table remains in place, for use
on fastpaths).

- Speed up scanning for expired routes by keeping a dedicated list.

- Speed up "generic" XDP by trying harder to avoid large allocations.

- Support attaching arbitrary metadata to netconsole messages.

Things we sprinkled into general kernel code:

- Enforce VM_IOREMAP flag and range in ioremap_page_range and
introduce VM_SPARSE kind and vm_area_[un]map_pages (used by
bpf_arena).

- Rework selftest harness to enable the use of the full range of ksft
exit code (pass, fail, skip, xfail, xpass).

Netfilter:

- Allow userspace to define a table that is exclusively owned by a
daemon (via netlink socket aliveness) without auto-removing this
table when the userspace program exits. Such table gets marked as
orphaned and a restarting management daemon can re-attach/regain
ownership.

- Speed up element insertions to nftables' concatenated-ranges set
type. Compact a few related data structures.

BPF:

- Add BPF token support for delegating a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application.

- Introduce bpf_arena which is sparse shared memory region between
BPF program and user space where structures inside the arena can
have pointers to other areas of the arena, and pointers work
seamlessly for both user-space programs and BPF programs.

- Introduce may_goto instruction that is a contract between the
verifier and the program. The verifier allows the program to loop
assuming it's behaving well, but reserves the right to terminate
it.

- Extend the BPF verifier to enable static subprog calls in spin lock
critical sections.

- Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops
type.

- Add support for retrieval of cookies for perf/kprobe multi links.

- Support arbitrary TCP SYN cookie generation / validation in the TC
layer with BPF to allow creating SYN flood handling in BPF
firewalls.

- Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF
objects.

Wireless:

- Add SPP (signaling and payload protected) AMSDU support.

- Support wider bandwidth OFDMA, as required for EHT operation.

Driver API:

- Major overhaul of the Energy Efficient Ethernet internals to
support new link modes (2.5GE, 5GE), share more code between
drivers (especially those using phylib), and encourage more
uniform behavior. Convert and clean up drivers.

- Define an API for querying per netdev queue statistics from
drivers.

- IPSec: account in global stats for fully offloaded sessions.

- Create a concept of Ethernet PHY Packages at the Device Tree level,
to allow parameterizing the existing PHY package code.

- Enable Rx hashing (RSS) on GTP protocol fields.

Misc:

- Improvements and refactoring all over networking selftests.

- Create uniform module aliases for TC classifiers, actions, and
packet schedulers to simplify creating modprobe policies.

- Address all missing MODULE_DESCRIPTION() warnings in networking.

- Extend the Netlink descriptions in YAML to cover message
encapsulation or "Netlink polymorphism", where interpretation of
nested attributes depends on link type, classifier type or some
other "class type".
