      Pull preemption Kconfig fix from Thomas Gleixner:
       "The PREEMPT_RT stub config renamed PREEMPT to PREEMPT_LL and defined
        PREEMPT outside of the menu and made it selectable by both PREEMPT_LL
        and PREEMPT_RT.
      
        Stupid me missed that 114 defconfigs select CONFIG_PREEMPT which
        obviously can't work anymore. oldconfig builds are affected as well,
        but it's more obvious as the user gets asked. [old]defconfig silently
        fixes it up and selects PREEMPT_NONE.
      
        Unbreak it by undoing the rename and adding a intermediate config
        symbol which is selected by both PREEMPT and PREEMPT_RT. That requires
        to chase down a few #ifdefs, but it's better than tweaking 114
        defconfigs and annoying users"

      sched/rt, Kconfig: Unbreak def/oldconfig with CONFIG_PREEMPT=y · b8d33498
      Thomas Gleixner authored
      The merge of the CONFIG_PREEMPT_RT stub renamed CONFIG_PREEMPT to
      CONFIG_PREEMPT_LL which causes all defconfigs which have CONFIG_PREEMPT=y
      set to fall back to CONFIG_PREEMPT_NONE because CONFIG_PREEMPT depends on
      the preemption mode choice wich defaults to NONE. This also affects
      oldconfig builds.
      
      So rather than changing 114 defconfig files and being an annoyance to
      users, revert the rename and select a new config symbol PREEMPTION. That
      keeps everything working smoothly and the revelant ifdef's are going to be
      fixed up step by step.

      pidfd: fix a poll race when setting exit_state · b191d649
      Suren Baghdasaryan authored
      There is a race between reading task->exit_state in pidfd_poll and
      writing it after do_notify_parent calls do_notify_pidfd. Expected
      sequence of events is:
      
      CPU 0                            CPU 1
      ------------------------------------------------
      exit_notify
        do_notify_parent
          do_notify_pidfd
        tsk->exit_state = EXIT_DEAD
                                        pidfd_poll
                                           if (tsk->exit_state)
      
      However nothing prevents the following sequence:
      
      CPU 0                            CPU 1
      ------------------------------------------------
      exit_notify
        do_notify_parent
          do_notify_pidfd
                                         pidfd_poll
                                            if (tsk->exit_state)
        tsk->exit_state = EXIT_DEAD
      
      This causes a polling task to wait forever, since poll blocks because
      exit_state is 0 and the waiting task is not notified again. A stress
      test continuously doing pidfd poll and process exits uncovered this bug.
      
      To fix it, we make sure that the task's exit_state is always set before
      calling do_notify_pidfd.

      tcp: be more careful in tcp_fragment() · b617158d
      Eric Dumazet authored
      Some applications set tiny SO_SNDBUF values and expect
      TCP to just work. Recent patches to address CVE-2019-11478
      broke them in case of losses, since retransmits might
      be prevented.
      
      We should allow these flows to make progress.
      
      This patch allows the first and last skb in retransmit queue
      to be split even if memory limits are hit.
      
      It also adds the some room due to the fact that tcp_sendmsg()
      and tcp_sendpage() might overshoot sk_wmem_queued by about one full
      TSO skb (64KB size). Note this allowance was already present
      in stable backports for kernels < 4.15
      
      Note for < 4.15 backports :
       tcp_rtx_queue_tail() will probably look like :
      
      static inline struct sk_buff *tcp_rtx_queue_tail(const struct sock *sk)
      {
      	struct sk_buff *skb = tcp_send_head(sk);
      
      	return skb ? tcp_write_queue_prev(sk, skb) : tcp_write_queue_tail(sk);
      }

      vrf: make sure skb->data contains ip header to make routing · 107e47cc
      Peter Kosyh authored
      vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing
      using ip/ipv6 addresses, but don't make sure the header is available
      in skb->data[] (skb_headlen() is less then header size).
      
      Case:
      
      1) igb driver from intel.
      2) Packet size is greater then 255.
      3) MPLS forwards to VRF device.
      
      So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound()
      functions.

      with nops while keeping the code which flushes the DTLB.
