      tcp/udp: Make early_demux back namespacified. · 11052589
      Kuniyuki Iwashima authored
      Commit e21145a9 ("ipv4: namespacify ip_early_demux sysctl knob") made
      it possible to enable/disable early_demux on a per-netns basis.  Then, we
      introduced two knobs, tcp_early_demux and udp_early_demux, to switch it for
      TCP/UDP in commit dddb64bc ("net: Add sysctl to toggle early demux for
      tcp and udp").  However, the .proc_handler() was wrong and actually
      disabled us from changing the behaviour in each netns.
      
      We can execute early_demux if net.ipv4.ip_early_demux is on and each proto
      .early_demux() handler is not NULL.  When we toggle (tcp|udp)_early_demux,
      the change itself is saved in each netns variable, but the .early_demux()
      handler is a global variable, so the handler is switched based on the
      init_net's sysctl variable.  Thus, netns (tcp|udp)_early_demux knobs have
      nothing to do with the logic.  Whether we CAN execute proto .early_demux()
      is always decided by init_net's sysctl knob, and whether we DO it or not is
      by each netns ip_early_demux knob.
      
      This patch namespacifies (tcp|udp)_early_demux again.  For now, the users
      of the .early_demux() handler are TCP and UDP only, and they are called
      directly to avoid retpoline.  So, we can remove the .early_demux() handler
      from inet6?_protos and need not dereference them in ip6?_rcv_finish_core().
      If another proto needs .early_demux(), we can restore it at that time.

      x86/speculation: Use DECLARE_PER_CPU for x86_spec_ctrl_current · db886979

      Clang warns:
      
        arch/x86/kernel/cpu/bugs.c:58:21: error: section attribute is specified on redeclared variable [-Werror,-Wsection]

        1 error generated.
      
      The declaration should be using DECLARE_PER_CPU instead so all
      attributes stay in sync.

      Pull networking fixes from Jakub Kicinski:
       "Including fixes from netfilter, bpf and wireless.
      
        Still no major regressions, the release continues to be calm. An
        uptick of fixes this time around due to trivial data race fixes and
        patches flowing down from subtrees.
      
        There has been a few driver fixes (particularly a few fixes for false
        positives due to 66e4c8d9 which went into -next in May!) that make
        me worry the wide testing is not exactly fully through.
      
        So "calm" but not "let's just cut the final ASAP" vibes over here.
      
        Current release - regressions:
      
         - wifi: rtw88: fix write to const table of channel parameters
      
        Current release - new code bugs:
      
         - mac80211: add gfp_t arg to ieeee80211_obss_color_collision_notify
      
         - mlx5:
            - TC, allow offload from uplink to other PF's VF
            - Lag, decouple FDB selection and shared FDB
            - Lag, correct get the port select mode str
      
         - bnxt_en: fix and simplify XDP transmit path
      
         - r8152: fix accessing unset transport header
      
        Previous releases - regressions:
      
         - conntrack: fix crash due to confirmed bit load reordering (after
           atomic -> refcount conversion)
      
         - stmmac: dwc-qos: disable split header for Tegra194
      
        Previous releases - always broken:
      
         - mlx5e: ring the TX doorbell on DMA errors
      
         - bpf: make sure mac_header was set before using it
      
         - mac80211: do not wake queues on a vif that is being stopped
      
         - mac80211: fix queue selection for mesh/OCB interfaces
      
         - ip: fix dflt addr selection for connected nexthop
      
         - seg6: fix skb checksums for SRH encapsulation/insertion
      
         - xdp: fix spurious packet loss in generic XDP TX path
      
         - bunch of sysctl data race fixes
      
         - nf_log: incorrect offset to network header
      
        Misc:
      
         - bpf: add flags arg to bpf_dynptr_read and bpf_dynptr_write APIs"
