      ipvlan: call dev_change_flags when ipvlan mode is reset · 5dc2d399
      Hangbin Liu authored
      After we change the ipvlan mode from l3 to l2, or vice versa, we only
      reset IFF_NOARP flag, but don't flush the ARP table cache, which will
      cause eth->h_dest to be equal to eth->h_source in ipvlan_xmit_mode_l2().
      Then the message will not come out of host.
      
      Here is the reproducer on local host:
      
      ip link set eth1 up
      ip addr add 192.168.1.1/24 dev eth1
      ip link add link eth1 ipvlan1 type ipvlan mode l3
      
      ip netns add net1
      ip link set ipvlan1 netns net1
      ip netns exec net1 ip link set ipvlan1 up
      ip netns exec net1 ip addr add 192.168.2.1/24 dev ipvlan1
      
      ip route add 192.168.2.0/24 via 192.168.1.2
      ping 192.168.2.2 -c 2
      
      ip netns exec net1 ip link set ipvlan1 type ipvlan mode l2
      ping 192.168.2.2 -c 2
      
      Add the same configuration on remote host. After we set the mode to l2,
      we could find that the src/dst MAC addresses are the same on eth1:
      
      21:26:06.648565 00:b7:13:ad:d3:05 > 00:b7:13:ad:d3:05, ethertype IPv4 (0x0800), length 98: (tos 0x0, ttl 64, id 58356, offset 0, flags [DF], proto ICMP (1), length 84)
          192.168.2.1 > 192.168.2.2: ICMP echo request, id 22686, seq 1, length 64
      
      Fix this by calling dev_change_flags(), which will call netdevice notifier
      with flag change info.
      
      v2:
      a) As pointed out by Wang Cong, check return value for dev_change_flags() when
      change dev flags.
      b) As suggested by Stefano and Sabrina, move flags setting before l3mdev_ops.
      So we don't need to redo ipvlan_{, un}register_nf_hook() again in err path.

      net: fix use-after-free in GRO with ESP · 603d4cf8
      Sabrina Dubroca authored
      Since the addition of GRO for ESP, gro_receive can consume the skb and
      return -EINPROGRESS. In that case, the lower layer GRO handler cannot
      touch the skb anymore.
      
      Commit 5f114163 ("net: Add a skb_gro_flush_final helper.") converted
      some of the gro_receive handlers that can lead to ESP's gro_receive so
      that they wouldn't access the skb when -EINPROGRESS is returned, but
      missed other spots, mainly in tunneling protocols.
      
      This patch finishes the conversion to using skb_gro_flush_final(), and
      adds a new helper, skb_gro_flush_final_remcsum(), used in VXLAN and
      GUE.

      tcp: prevent bogus FRTO undos with non-SACK flows · 1236f22f
      Ilpo Järvinen authored
      If SACK is not enabled and the first cumulative ACK after the RTO
      retransmission covers more than the retransmitted skb, a spurious
      FRTO undo will trigger (assuming FRTO is enabled for that RTO).
      The reason is that any non-retransmitted segment acknowledged will
      set FLAG_ORIG_SACK_ACKED in tcp_clean_rtx_queue even if there is
      no indication that it would have been delivered for real (the
      scoreboard is not kept with TCPCB_SACKED_ACKED bits in the non-SACK
      case so the check for that bit won't help like it does with SACK).
      Having FLAG_ORIG_SACK_ACKED set results in the spurious FRTO undo
      in tcp_process_loss.
      
      We need to use more strict condition for non-SACK case and check
      that none of the cumulatively ACKed segments were retransmitted
      to prove that progress is due to original transmissions. Only then
      keep FLAG_ORIG_SACK_ACKED set, allowing FRTO undo to proceed in
      non-SACK case.
      
      (FLAG_ORIG_SACK_ACKED is planned to be renamed to FLAG_ORIG_PROGRESS
      to better indicate its purpose but to keep this change minimal, it
      will be done in another patch).
      
      Besides burstiness and congestion control violations, this problem
      can result in RTO loop: When the loss recovery is prematurely
      undoed, only new data will be transmitted (if available) and
      the next retransmission can occur only after a new RTO which in case
      of multiple losses (that are not for consecutive packets) requires
      one RTO per loss to recover.

      openrisc: entry: Fix delay slot exception detection · ae15a41a
      Stafford Horne authored
      Originally in patch e6d20c55 ("openrisc: entry: Fix delay slot
      detection") I fixed delay slot detection, but only for QEMU.  We missed
      that hardware delay slot detection using delay slot exception flag (DSX)
      was still broken.  This was because QEMU set the DSX flag in both
      pre-exception supervision register (ESR) and supervision register (SR)
      register, but on real hardware the DSX flag is only set on the SR
      register during exceptions.
      
      Fix this by carrying the DSX flag into the SR register during exception.
      We also update the DSX flag read locations to read the value from the SR
      register not the pt_regs SR register which represents ESR.  The ESR
      should never have the DSX flag set.
      
      In the process I updated/removed a few comments to match the current
      state.  Including removing a comment saying that the DSX detection logic
      was inefficient and needed to be rewritten.
      
      I have tested this on QEMU with a patch ensuring it matches the hardware
      specification.

      ====================
      pull-request: bpf 2018-07-01
      
      The following pull-request contains BPF updates for your *net* tree.
      
      The main changes are:
      
      1) A bpf_fib_lookup() helper fix to change the API before freeze to
         return an encoding of the FIB lookup result and return the nexthop
         device index in the params struct (instead of device index as return
         code that we had before), from David.
      
      2) Various BPF JIT fixes to address syzkaller fallout, that is, do not
         reject progs when set_memory_*() fails since it could still be RO.
         Also arm32 JIT was not using bpf_jit_binary_lock_ro() API which was
         an issue, and a memory leak in s390 JIT found during review, from
         Daniel.
      
      3) Multiple fixes for sockmap/hash to address most of the syzkaller
         triggered bugs. Usage with IPv6 was crashing, a GPF in bpf_tcp_close(),
         a missing sock_map_release() routine to hook up to callbacks, and a
         fix for an omitted bucket lock in sock_close(), from John.
      
      4) Two bpftool fixes to remove duplicated error message on program load,
         and another one to close the libbpf object after program load. One
         additional fix for nfp driver's BPF offload to avoid stopping offload
         completely if replace of program failed, from Jakub.
      
      5) Couple of BPF selftest fixes that bail out in some of the test
         scripts if the user does not have the right privileges, from Jeffrin.
      
      6) Fixes in test_bpf for s390 when CONFIG_BPF_JIT_ALWAYS_ON is set
         where we need to set the flag that some of the test cases are expected
         to fail, from Kleber.
      
      7) Fix to detangle BPF_LIRC_MODE2 dependency from CONFIG_CGROUP_BPF
         since it has no relation to it and lirc2 users often have configs
         without cgroups enabled and thus would not be able to use it, from Sean.
      
      8) Fix a selftest failure in sockmap by removing a useless setrlimit()
         call that would set a too low limit where at the same time we are
         already including bpf_rlimit.h that does the job, from Yonghong.
      
      9) Fix BPF selftest config with missing missing NET_SCHED, from Anders.
