Merge tag 'net-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bluetooth, netfilter, WiFi.

  Feels like an up-tick in regression fixes, mostly for older releases.
  The hfsc fix, tcp_disconnect() and Intel WWAN fixes stand out as
  fairly clear-cut user reported regressions. The mlx5 DMA bug was
  causing strife for 390x folks. The fixes themselves are not
  particularly scary, tho. No open investigations / outstanding reports
  at the time of writing.

  Current release - regressions:

   - eth: mlx5: perform DMA operations in the right locations, make
     devices usable on s390x, again

   - sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner
     curve, previous fix of rejecting invalid config broke some scripts

   - rfkill: reduce data->mtx scope in rfkill_fop_open, avoid deadlock

   - revert "ethtool: Fix mod state of verbose no_mask bitset", needs
     more work

  Current release - new code bugs:

   - tcp: fix listen() warning with v4-mapped-v6 address

  Previous releases - regressions:

   - tcp: allow tcp_disconnect() again when threads are waiting, it was
     denied to plug a constant source of bugs but turns out .NET depends
     on it

   - eth: mlx5: fix double-free if buffer refill fails under OOM

   - revert "net: wwan: iosm: enable runtime pm support for 7560", it's
     causing regressions and the WWAN team at Intel disappeared

   - tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a
     single skb, fix single-stream perf regression on some devices

  Previous releases - always broken:

   - Bluetooth:
      - fix issues in legacy BR/EDR PIN code pairing
      - correctly bounds check and pad HCI_MON_NEW_INDEX name

   - netfilter:
      - more fixes / follow ups for the large "commit protocol" rework,
        which went in as a fix to 6.5
      - fix null-derefs on netlink attrs which user may not pass in

   - tcp: fix excessive TLP and RACK timeouts from HZ rounding (bless
     Debian for keeping HZ=250 alive)

   - net: more strict VIRTIO_NET_HDR_GSO_UDP_L4 validation, prevent
     letting frankenstein UDP super-frames from getting into the stack

   - net: fix interface altnames when ifc moves to a new namespace

   - eth: qed: fix the size of the RX buffers

   - mptcp: avoid sending RST when closing the initial subflow"

* tag 'net-6.6-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (94 commits)
  Revert "ethtool: Fix mod state of verbose no_mask bitset"
  selftests: mptcp: join: no RST when rm subflow/addr
  mptcp: avoid sending RST when closing the initial subflow
  mptcp: more conservative check for zero probes
  tcp: check mptcp-level constraints for backlog coalescing
  selftests: mptcp: join: correctly check for no RST
  net: ti: icssg-prueth: Fix r30 CMDs bitmasks
  selftests: net: add very basic test for netdev names and namespaces
  net: move altnames together with the netdevice
  net: avoid UAF on deleted altname
  net: check for altname conflicts when changing netdev's netns
  net: fix ifname in netlink ntf during netns move
  net: ethernet: ti: Fix mixed module-builtin object
  net: phy: bcm7xxx: Add missing 16nm EPHY statistics
  ipv4: fib: annotate races around nh->nh_saddr_genid and nh->nh_saddr
  tcp_bpf: properly release resources on error paths
  net/sched: sch_hfsc: upgrade 'rt' to 'sc' when it becomes a inner curve
  net: mdio-mux: fix C45 access returning -EIO after API change
  tcp: tsq: relax tcp_small_queue_check() when rtx queue contains a single skb
  octeon_ep: update BQL sent bytes before ringing doorbell
