Merge tag 'net-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Jakub Kicinski:
 "Including fixes from bluetooth, bpf, can and netfilter.

  A little larger than usual but it's all fixes, no late features. It's
  large partially because of timing, and partially because of follow ups
  to stuff that got merged a week or so before the merge window and
  wasn't as widely tested. Maybe the Bluetooth fixes are a little
  alarming so we'll address that, but the rest seems okay and not scary.

  Notably we're including a fix for the netfilter Kconfig [1], your WiFi
  warning [2] and a bluetooth fix which should unblock syzbot [3].

  Current release - regressions:

   - Bluetooth:
      - don't try to cancel uninitialized works [3]
      - L2CAP: fix use-after-free caused by l2cap_chan_put

   - tls: rx: fix device offload after recent rework

   - devlink: fix UAF on failed reload and leftover locks in mlxsw

  Current release - new code bugs:

   - netfilter:
      - flowtable: fix incorrect Kconfig dependencies [1]
      - nf_tables: fix crash when nf_trace is enabled

   - bpf:
      - use proper target btf when exporting attach_btf_obj_id
      - arm64: fixes for bpf trampoline support

   - Bluetooth:
      - ISO: unlock on error path in iso_sock_setsockopt()
      - ISO: fix info leak in iso_sock_getsockopt()
      - ISO: fix iso_sock_getsockopt for BT_DEFER_SETUP
      - ISO: fix memory corruption on iso_pinfo.base
      - ISO: fix not using the correct QoS
      - hci_conn: fix updating ISO QoS PHY

   - phy: dp83867: fix get nvmem cell fail

  Previous releases - regressions:

   - wifi: cfg80211: fix validating BSS pointers in
     __cfg80211_connect_result [2]

   - atm: bring back zatm uAPI after ATM had been removed

   - properly fix old bug making bonding ARP monitor mode not being able
     to work with software devices with lockless Tx

   - tap: fix null-deref on skb->dev in dev_parse_header_protocol

   - revert "net: usb: ax88179_178a needs FLAG_SEND_ZLP" it helps some
     devices and breaks others

   - netfilter:
      - nf_tables: many fixes rejecting cross-object linking which may
        lead to UAFs
      - nf_tables: fix null deref due to zeroed list head
      - nf_tables: validate variable length element extension

   - bgmac: fix a BUG triggered by wrong bytes_compl

   - bcmgenet: indicate MAC is in charge of PHY PM

  Previous releases - always broken:

   - bpf:
      - fix bad pointer deref in bpf_sys_bpf() injected via test infra
      - disallow non-builtin bpf programs calling the prog_run command
      - don't reinit map value in prealloc_lru_pop
      - fix UAFs during the read of map iterator fd
      - fix invalidity check for values in sk local storage map
      - reject sleepable program for non-resched map iterator

   - mptcp:
      - move subflow cleanup in mptcp_destroy_common()
      - do not queue data on closed subflows

   - virtio_net: fix memory leak inside XDP_TX with mergeable

   - vsock: fix memory leak when multiple threads try to connect()

   - rework sk_user_data sharing to prevent psock leaks

   - geneve: fix TOS inheriting for ipv4

   - tunnels & drivers: do not use RT_TOS for IPv6 flowlabel

   - phy: c45 baset1: do not skip aneg configuration if clock role is
     not specified

   - rose: avoid overflow when /proc displays timer information

   - x25: fix call timeouts in blocking connects

   - can: mcp251x: fix race condition on receive interrupt

   - can: j1939:
      - replace user-reachable WARN_ON_ONCE() with netdev_warn_once()
      - fix memory leak of skbs in j1939_session_destroy()

  Misc:

   - docs: bpf: clarify that many things are not uAPI

   - seg6: initialize induction variable to first valid array index (to
     silence clang vs objtool warning)

   - can: ems_usb: fix clang 14's -Wunaligned-access warning"
