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

  Current release - regressions:

   - sched: fix SKB_NOT_DROPPED_YET splat under debug config

  Current release - new code bugs:

   - tcp:
       - fix usec timestamps with TCP fastopen
       - fix possible out-of-bounds reads in tcp_hash_fail()
       - fix SYN option room calculation for TCP-AO

   - tcp_sigpool: fix some off by one bugs

   - bpf: fix compilation error without CGROUPS

   - ptp:
       - ptp_read() should not release queue
       - fix tsevqs corruption

  Previous releases - regressions:

   - llc: verify mac len before reading mac header

  Previous releases - always broken:

   - bpf:
       - fix check_stack_write_fixed_off() to correctly spill imm
       - fix precision tracking for BPF_ALU | BPF_TO_BE | BPF_END
       - check map->usercnt after timer->timer is assigned

   - dsa: lan9303: consequently nested-lock physical MDIO

   - dccp/tcp: call security_inet_conn_request() after setting IP addr

   - tg3: fix the TX ring stall due to incorrect full ring handling

   - phylink: initialize carrier state at creation

   - ice: fix direction of VF rules in switchdev mode

  Misc:

   - fill in a bunch of missing MODULE_DESCRIPTION()s, more to come"
