Merge tag 'net-6.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net
Pull networking fixes from Paolo Abeni:
"Current release - regressions:
- tcp: fix tcp_disordered_ack() vs usec TS resolution
Current release - new code bugs:
- dpll: sanitize possible null pointer dereference in
dpll_pin_parent_pin_set()
- eth: octeon_ep: initialise control mbox tasks before using APIs
Previous releases - regressions:
- io_uring/af_unix: disable sending io_uring over sockets
- eth: mlx5e:
- TC, don't offload post action rule if not supported
- fix possible deadlock on mlx5e_tx_timeout_work
- eth: iavf: fix iavf_shutdown to call iavf_remove instead iavf_close
- eth: bnxt_en: fix skb recycling logic in bnxt_deliver_skb()
- eth: ena: fix DMA syncing in XDP path when SWIOTLB is on
- eth: team: fix use-after-free when an option instance allocation
fails
Previous releases - always broken:
- neighbour: don't let neigh_forced_gc() disable preemption for long
- net: prevent mss overflow in skb_segment()
- ipv6: support reporting otherwise unknown prefix flags in
RTM_NEWPREFIX
- tcp: remove acked SYN flag from packet in the transmit queue
correctly
- eth: octeontx2-af:
- fix a use-after-free in rvu_nix_register_reporters
- fix promisc mcam entry action
- eth: dwmac-loongson: make sure MDIO is initialized before use
- eth: atlantic: fix double free in ring reinit logic"
