Linus Torvalds 8096acd744 Networking fixes for 5.14-rc2, including fixes from bpf and netfilter.
Current release - regressions:
 
  - sock: fix parameter order in sock_setsockopt()
 
 Current release - new code bugs:
 
  - netfilter: nft_last:
      - fix incorrect arithmetic when restoring last used
      - honor NFTA_LAST_SET on restoration
 
 Previous releases - regressions:
 
  - udp: properly flush normal packet at GRO time
 
  - sfc: ensure correct number of XDP queues; don't allow enabling the
         feature if there isn't sufficient resources to Tx from any CPU
 
  - dsa: sja1105: fix address learning getting disabled on the CPU port
 
  - mptcp: addresses a rmem accounting issue that could keep packets
         in subflow receive buffers longer than necessary, delaying
 	MPTCP-level ACKs
 
  - ip_tunnel: fix mtu calculation for ETHER tunnel devices
 
  - do not reuse skbs allocated from skbuff_fclone_cache in the napi
    skb cache, we'd try to return them to the wrong slab cache
 
  - tcp: consistently disable header prediction for mptcp
 
 Previous releases - always broken:
 
  - bpf: fix subprog poke descriptor tracking use-after-free
 
  - ipv6:
       - allocate enough headroom in ip6_finish_output2() in case
         iptables TEE is used
       - tcp: drop silly ICMPv6 packet too big messages to avoid
         expensive and pointless lookups (which may serve as a DDOS
 	vector)
       - make sure fwmark is copied in SYNACK packets
       - fix 'disable_policy' for forwarded packets (align with IPv4)
 
  - netfilter: conntrack: do not renew entry stuck in tcp SYN_SENT state
 
  - netfilter: conntrack: do not mark RST in the reply direction coming
       after SYN packet for an out-of-sync entry
 
  - mptcp: cleanly handle error conditions with MP_JOIN and syncookies
 
  - mptcp: fix double free when rejecting a join due to port mismatch
 
  - validate lwtstate->data before returning from skb_tunnel_info()
 
  - tcp: call sk_wmem_schedule before sk_mem_charge in zerocopy path
 
  - mt76: mt7921: continue to probe driver when fw already downloaded
 
  - bonding: fix multiple issues with offloading IPsec to (thru?) bond
 
  - stmmac: ptp: fix issues around Qbv support and setting time back
 
  - bcmgenet: always clear wake-up based on energy detection
 
 Misc:
 
  - sctp: move 198 addresses from unusable to private scope
 
  - ptp: support virtual clocks and timestamping
 
  - openvswitch: optimize operation for key comparison
