Pull networking fixes from Jakub Kicinski: "Including fixes from bpf and netfilter. Current release - regressions: - veth: fix packet segmentation in veth_convert_skb_to_xdp_buff Current release - new code bugs: - tcp: assorted fixes to the new Auth Option support Older releases - regressions: - tcp: fix mid stream window clamp - tls: fix incorrect splice handling - ipv4: ip_gre: handle skb_pull() failure in ipgre_xmit() - dsa: mv88e6xxx: restore USXGMII support for 6393X - arcnet: restore support for multiple Sohard Arcnet cards Older releases - always broken: - tcp: do not accept ACK of bytes we never sent - require admin privileges to receive packet traces via netlink - packet: move reference count in packet_sock to atomic_long_t - bpf: - fix incorrect branch offset comparison with cpu=v4 - fix prog_array_map_poke_run map poke update - netfilter: - three fixes for crashes on bad admin commands - xt_owner: fix race accessing sk->sk_socket, TOCTOU null-deref - nf_tables: fix 'exist' matching on bigendian arches - leds: netdev: fix RTNL handling to prevent potential deadlock - eth: tg3: prevent races in error/reset handling - eth: r8169: fix rtl8125b PAUSE storm when suspended - eth: r8152: improve reset and surprise removal handling - eth: hns: fix race between changing features and sending - eth: nfp: fix sleep in atomic for bonding offload" * tag 'net-6.7-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (62 commits) vsock/virtio: fix "comparison of distinct pointer types lacks a cast" warning net/smc: fix missing byte order conversion in CLC handshake net: dsa: microchip: provide a list of valid protocols for xmit handler drop_monitor: Require 'CAP_SYS_ADMIN' when joining "events" group psample: Require 'CAP_NET_ADMIN' when joining "packets" group bpf: sockmap, updating the sg structure should also update curr net: tls, update curr on splice as well nfp: flower: fix for take a mutex lock in soft irq context and rcu lock net: dsa: mv88e6xxx: Restore USXGMII support for 6393X tcp: do not accept ACK of bytes we never sent selftests/bpf: Add test for early update in prog_array_map_poke_run bpf: Fix prog_array_map_poke_run map poke update netfilter: xt_owner: Fix for unsafe access of sk->sk_socket netfilter: nf_tables: validate family when identifying table via handle netfilter: nf_tables: bail out on mismatching dynset and set expressions netfilter: nf_tables: fix 'exist' matching on bigendian arches netfilter: nft_set_pipapo: skip inactive elements during set walk netfilter: bpf: fix bad registration on nf_defrag leds: trigger: netdev: fix RTNL handling to prevent potential deadlock octeontx2-af: Update Tx link register range ...
