Merge tag 'net-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive window and the rcv_buf more strict. With increased use of HW aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap, improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI instance basis rather than a whole device. Fully stop the kernel NAPI thread when threaded NAPI gets disabled. Previously thread would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink
- Add a new neighbor flag ("extern_valid"), which cedes refresh responsibilities to userspace. This is needed for EVPN multi-homing where a neighbor entry for a multi-homed host needs to be synced across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister netconsole's console when all net targets are removed. Code refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol should be used for an inbound SA lookup
- Support inspecting ref_tracker state via DebugFS
- Don't force bonding advertisement frames tx to ~333 ms boundaries. Add broadcast_neighbor option to send ARP/ND on all bonded links
- Allow providing upcall pid for the 'execute' command in openvswitch
- Remove DCCP support from Netfilter's conntrack
- Disallow multiple packet duplications in the queuing layer
- Prevent use of deprecated iptables code on PREEMPT_RT
Driver API:
- Support RSS and hashing configuration over ethtool Netlink
- Add dedicated ethtool callbacks for getting and setting hashing fields
- Add support for power budget evaluation strategy in PSE / Power-over-Ethernet. Generate Netlink events for overcurrent etc
- Support DPLL phase offset monitoring across all device inputs. Support providing clock reference and SYNC over separate DPLL inputs
- Support traffic classes in devlink rate API for bandwidth management
- Remove rtnl_lock dependency from UDP tunnel port configuration

Merge tag 'net-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Jakub Kicinski: "Core & protocols:
- Continue Netlink conversions to per-namespace RTNL lock (IPv4 routing, routing rules, routing next hops, ARP ioctls)
- Continue extending the use of netdev instance locks. As a driver opt-in protect queue operations and (in due course) ethtool operations with the instance lock and not RTNL lock.
- Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance.
- Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring.
- Optimize MPTCP performance in single subflow mode by 29%.
- Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x.
- Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock. Bring an additional 229% improvement by tweaking hash distribution.
- Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%.
- Avoid skb_clone() dance in ping_rcv() to improve performance under ping flood.
- Avoid FIB lookup in netfilter if socket is available, 20% perf win.
- Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles. There are up to 4 namespace roles but we used to have just 2 netns pointer arguments, interpreted differently based on context.
- Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access.
- Add a new sysctl and sockopt for capping max retransmit timeout in TCP.
- Support masking port and DSCP in routing rule matches.
- Support dumping IPv4 multicast addresses with RTM_GETMULTICAST.
- Support specifying at what time packet should be sent on AF_XDP sockets.
- Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users.
- Add Netlink YAML spec for WiFi (nl80211) and conntrack.
- Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module.
- Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging.
- Allow users to specify source port range for GENEVE tunnels.
- netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata
Driver API:
- Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers. Delegate the responsibilities to phylink where possible. Improve its handling in phylib.
- Support symmetric OR-XOR RSS hashing algorithm.
- Support tracking and preserving IRQ affinity by NAPI itself.
- Support loopback mode speed selection for interface selftests.
Device drivers:
- Remove the IBM LCS driver for s390

Merge branch 'add-sock_kmemdup-helper'
Geliang Tang says:
==================== add sock_kmemdup helper
While developing MPTCP BPF path manager [1], I found it's useful to add a new sock_kmemdup() helper.
My use case is this:
In mptcp_userspace_pm_append_new_local_addr() function (see patch 3 in this patchset), it uses sock_kmalloc() to allocate an address entry "e", then immediately duplicate the input "entry" to it:
''' e = sock_kmalloc(sk, sizeof(*e), GFP_ATOMIC); if (!e) { ret = -ENOMEM; goto append_err; }
*e = *entry; '''
When I implemented MPTCP BPF path manager, I needed to implement a code similar to this in BPF.
The kfunc sock_kmalloc() can be easily invoked in BPF to allocate an entry "e", but the code "*e = *entry;" that assigns "entry" to "e" is not easy to implemented.
I had to implement such a "copy entry" helper in BPF:
''' static void mptcp_pm_copy_addr(struct mptcp_addr_info *dst, struct mptcp_addr_info *src) { dst->id = src->id; dst->family = src->family; dst->port = src->port;
if (src->family == AF_INET) { dst->addr.s_addr = src->addr.s_addr; } else if (src->family == AF_INET6) { dst->addr6.s6_addr32[0] = src->addr6.s6_addr32[0]; dst->addr6.s6_addr32[1] = src->addr6.s6_addr32[1]; dst->addr6.s6_addr32[2] = src->addr6.s6_addr32[2]; dst->addr6.s6_addr32[3] = src->addr6.s6_addr32[3]; } }
static void mptcp_pm_copy_entry(struct mptcp_pm_addr_entry *dst, struct mptcp_pm_addr_entry *src) { mptcp_pm_copy_addr(&dst->addr, &src->addr);
dst->flags = src->flags; dst->ifindex = src->ifindex; } '''
And add "write permission" for BPF to each field of mptcp_pm_addr_entry:
''' @@ static int bpf_mptcp_pm_btf_struct_access(struct bpf_verifier_log *log, case offsetof(struct mptcp_pm_addr_entry, addr.port): end = offsetofend(struct mptcp_pm_addr_entry, addr.port); break; #if IS_ENABLED(CONFIG_MPTCP_IPV6) case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[0]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[1]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[2]); break; case offsetof(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr6.s6_addr32[3]); break; #else case offsetof(struct mptcp_pm_addr_entry, addr.addr.s_addr): end = offsetofend(struct mptcp_pm_addr_entry, addr.addr.s_addr); break; #endif '''
But if there's a sock_kmemdup() helper, it will become much simpler, only need to call kfunc sock_kmemdup() instead in BPF.
So this patchset adds this new helper and uses it in several places.

net: use sock_kmemdup for ip_options
Instead of using sock_kmalloc() to allocate an ip_options and then immediately duplicate another ip_options to the newly allocated one in ipv6_dup_options(), mptcp_copy_ip_options() and sctp_v4_copy_ip_options(), the newly added sock_kmemdup() helper can be used to simplify the code.

Merge tag 'asoc-fix-v6.9-rc2' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus
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.
