Merge tag 'net-6.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski: "Including fixes from bpf and wireless. Nothing scary here. Feels like the first wave of regressions from v6.5 is addressed - one outstanding fix still to come in TLS for the sendpage rework. Current release - regressions: - udp: fix __ip_append_data()'s handling of MSG_SPLICE_PAGES - dsa: fix older DSA drivers using phylink Previous releases - regressions: - gro: fix misuse of CB in udp socket lookup - mlx5: unregister devlink params in case interface is down - Revert "wifi: ath11k: Enable threaded NAPI" Previous releases - always broken: - sched: cls_u32: fix match key mis-addressing - sched: bind logic fixes for cls_fw, cls_u32 and cls_route - add bound checks to a number of places which hand-parse netlink - bpf: disable preemption in perf_event_output helpers code - qed: fix scheduling in a tasklet while getting stats - avoid using APIs which are not hardirq-safe in couple of drivers, when we may be in a hard IRQ (netconsole) - wifi: cfg80211: fix return value in scan logic, avoid page allocator warning - wifi: mt76: mt7615: do not advertise 5 GHz on first PHY of MT7615D (DBDC) Misc: - drop handful of inactive maintainers, put some new in place" * tag 'net-6.5-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (98 commits) MAINTAINERS: update TUN/TAP maintainers test/vsock: remove vsock_perf executable on `make clean` tcp_metrics: fix data-race in tcpm_suck_dst() vs fastopen tcp_metrics: annotate data-races around tm->tcpm_net tcp_metrics: annotate data-races around tm->tcpm_vals[] tcp_metrics: annotate data-races around tm->tcpm_lock tcp_metrics: annotate data-races around tm->tcpm_stamp tcp_metrics: fix addr_same() helper prestera: fix fallback to previous version on same major version udp: Fix __ip_append_data()'s handling of MSG_SPLICE_PAGES net/mlx5e: Set proper IPsec source port in L4 selector net/mlx5: fs_core: Skip the FTs in the same FS_TYPE_PRIO_CHAINS fs_prio net/mlx5: fs_core: Make find_closest_ft more generic wifi: brcmfmac: Fix field-spanning write in brcmf_scan_params_v2_to_v1() vxlan: Fix nexthop hash size ip6mr: Fix skb_under_panic in ip6mr_cache_report() s390/qeth: Don't call dev_close/dev_open (DOWN/UP) net: tap_open(): set sk_uid from current_fsuid() net: tun_chr_open(): set sk_uid from current_fsuid() net: dcb: choose correct policy to parse DCB_ATTR_BCN ...
