Merge tag 'net-next-6.6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking updates from Paolo Abeni:
"Core:
- Increase size limits for to-be-sent skb frag allocations. This
allows tun, tap devices and packet sockets to better cope with
large writes operations
- Store netdevs in an xarray, to simplify iterating over netdevs
- Refactor nexthop selection for multipath routes
- Improve sched class lifetime handling
- Add backup nexthop ID support for bridge
- Implement drop reasons support in openvswitch
- Several data races annotations and fixes
- Constify the sk parameter of routing functions
- Prepend kernel version to netconsole message
Protocols:
- Implement support for TCP probing the peer being under memory
pressure
- Remove hard coded limitation on IPv6 specific info placement inside
the socket struct
- Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per
socket scaling factor
- Scaling-up the IPv6 expired route GC via a separated list of
expiring routes
- In-kernel support for the TLS alert protocol
- Better support for UDP reuseport with connected sockets
- Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR
header size
- Get rid of additional ancillary per MPTCP connection struct socket
- Implement support for BPF-based MPTCP packet schedulers
- Format MPTCP subtests selftests results in TAP
- Several new SMC 2.1 features including unique experimental options,
max connections per lgr negotiation, max links per lgr negotiation
BPF:
- Multi-buffer support in AF_XDP
- Add multi uprobe BPF links for attaching multiple uprobes and usdt
probes, which is significantly faster and saves extra fds
- Implement an fd-based tc BPF attach API (TCX) and BPF link support
on top of it
- Add SO_REUSEPORT support for TC bpf_sk_assign
- Support new instructions from cpu v4 to simplify the generated code
and feature completeness, for x86, arm64, riscv64
- Support defragmenting IPv(4|6) packets in BPF
- Teach verifier actual bounds of bpf_get_smp_processor_id() and fix
perf+libbpf issue related to custom section handling
- Introduce bpf map element count and enable it for all program types
- Add a BPF hook in sys_socket() to change the protocol ID from
IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy
- Introduce bpf_me_mcache_free_rcu() and fix OOM under stress
- Add uprobe support for the bpf_get_func_ip helper
- Check skb ownership against full socket
- Support for up to 12 arguments in BPF trampoline
- Extend link_info for kprobe_multi and perf_event links
Netfilter:
- Speed-up process exit by aborting ruleset validation if a fatal
signal is pending
- Allow NLA_POLICY_MASK to be used with BE16/BE32 types
Driver API:
- Page pool optimizations, to improve data locality and cache usage
- Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the
need for raw ioctl() handling in drivers
- Simplify genetlink dump operations (doit/dumpit) providing them the
common information already populated in struct genl_info
- Extend and use the yaml devlink specs to [re]generate the split ops
- Introduce devlink selective dumps, to allow SF filtering SF based
on handle and other attributes
- Add yaml netlink spec for netlink-raw families, allow route, link
and address related queries via the ynl tool
- Remove phylink legacy mode support
- Support offload LED blinking to phy
- Add devlink port function attributes for IPsec
