Merge branch 'selftests-forwarding-vxlan_bridge_1q_mc_ul-fix-flakiness'
Petr Machata says:
==================== selftests: forwarding: vxlan_bridge_1q_mc_ul: Fix flakiness
The net/forwarding/vxlan_bridge_1q_mc_ul selftest runs an overlay traffic, forwarded over a multicast-routed VXLAN underlay. In order to determine whether packets reach their intended destination, it uses a TC match. For convenience, it uses a flower match, which however does not allow matching on the encapsulated packet. So various service traffic ends up being indistinguishable from the test packets, and ends up confusing the test. To alleviate the problem, the test uses sleep to allow the necessary service traffic to run and clear the channel, before running the test traffic. This worked for a while, but lately we have nevertheless seen flakiness of the test in the CI.
In this patchset, first generalize tc_rule_stats_get() to support u32 in patch #1, then in patch #2 convert the test to use u32 to allow parsing deeper into the packet, and in #3 drop the now-unnecessary sleep. ====================

This worked for a while, but lately we have nevertheless seen flakiness of the test in the CI.
Fix the issue by using u32 to match the encapsulated packet as well. The confusing packets seem to always be IPv6 multicast listener reports. Realistically they could be ARP or other ICMP6 traffic as well. Therefore look for ethertype IPv4 in the IPv4 traffic test, and for IPv6 / UDP combination in the IPv6 traffic test.

Merge tag 'net-next-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni: "Core:
- Implement the Device Memory TCP transmit path, allowing zero-copy data transmission on top of TCP from e.g. GPU memory to the wire.
- Move all the IPv6 routing tables management outside the RTNL scope, under its own lock and RCU. The route control path is now 3x times faster.
- Convert queue related netlink ops to instance lock, reducing again the scope of the RTNL lock. This improves the control plane scalability.
- Refactor the software crc32c implementation, removing unneeded abstraction layers and improving significantly the related micro-benchmarks.
- Optimize the GRO engine for UDP-tunneled traffic, for a 10% performance improvement in related stream tests.
- Cover more per-CPU storage with local nested BH locking; this is a prep work to remove the current per-CPU lock in local_bh_disable() on PREMPT_RT.
- Introduce and use nlmsg_payload helper, combining buffer bounds verification with accessing payload carried by netlink messages.
Netfilter:
- Rewrite the procfs conntrack table implementation, improving considerably the dump performance. A lot of user-space tools still use this interface.
- Implement support for wildcard netdevice in netdev basechain and flowtables.
- Integrate conntrack information into nft trace infrastructure.
- Export set count and backend name to userspace, for better introspection.
BPF:
- BPF qdisc support: BPF-qdisc can be implemented with BPF struct_ops programs and can be controlled in similar way to traditional qdiscs using the "tc qdisc" command.
- Refactor the UDP socket iterator, addressing long standing issues WRT duplicate hits or missed sockets.
Protocols:
- Improve TCP receive buffer auto-tuning and increase the default upper bound for the receive buffer; overall this improves the single flow maximum thoughput on 200Gbs link by over 60%.
- Add AFS GSSAPI security class to AF_RXRPC; it provides transport security for connections to the AFS fileserver and VL server.
- Improve TCP multipath routing, so that the sources address always matches the nexthop device.
- Introduce SO_PASSRIGHTS for AF_UNIX, to allow disabling SCM_RIGHTS, and thus preventing DoS caused by passing around problematic FDs.
- Retire DCCP socket. DCCP only receives updates for bugs, and major distros disable it by default. Its removal allows for better organisation of TCP fields to reduce the number of cache lines hit in the fast path.
- Extend TCP drop-reason support to cover PAWS checks.
Driver API:
- Reorganize PTP ioctl flag support to require an explicit opt-in for the drivers, avoiding the problem of drivers not rejecting new unsupported flags.
- Converted several device drivers to timestamping APIs.
- Introduce per-PHY ethtool dump helpers, improving the support for dump operations targeting PHYs.
Tests and tooling:
- Add support for classic netlink in user space C codegen, so that ynl-c can now read, create and modify links, routes addresses and qdisc layer configuration.
- Add ynl sub-types for binary attributes, allowing ynl-c to output known struct instead of raw binary data, clarifying the classic netlink output.
- Extend MPTCP selftests to improve the code-coverage.
- Add tests for XDP tail adjustment in AF_XDP.
New hardware / drivers:
- OpenVPN virtual driver: offload OpenVPN data channels processing to the kernel-space, increasing the data transfer throughput WRT the user-space implementation.
- Renesas glue driver for the gigabit ethernet RZ/V2H(P) SoC.
- Broadcom asp-v3.0 ethernet driver.
- AMD Renoir ethernet device.
- ReakTek MT9888 2.5G ethernet PHY driver.
- Aeonsemi 10G C45 PHYs driver.

Merge branch 'bridge-mc-per-vlan-qquery'
Yong Wang says:
==================== bridge: multicast: per vlan query improvement when port or vlan state changes
The current implementation of br_multicast_enable_port() only operates on port's multicast context, which doesn't take into account in case of vlan snooping, one downside is the port's igmp query timer will NOT resume when port state gets changed from BR_STATE_BLOCKING to BR_STATE_FORWARDING etc.
Such code flow will briefly look like: 1.vlan snooping --> br_multicast_port_query_expired with per vlan port_mcast_ctx --> port in BR_STATE_BLOCKING state --> then one-shot timer discontinued
The port state could be changed by STP daemon or kernel STP, taking mstpd as example:
2.mstpd --> netlink_sendmsg --> br_setlink --> br_set_port_state with non blocking states, i.e. BR_STATE_LEARNING or BR_STATE_FORWARDING --> br_port_state_selection --> br_multicast_enable_port --> enable multicast with port's multicast_ctx
Here for per vlan snooping, the vlan context of the port should be used instead of port's multicast_ctx. The first patch corrects such behavior.
Similarly, vlan state change also impacts multicast behavior, the 2nd patch adds function to update the corresponding multicast context when vlan state changes.
The 3rd patch adds the selftests to confirm that IGMP/MLD query does happen when the STP state becomes forwarding. ====================
