      Andrey Konovalov reported crashes in ipv4_mtu()
      
      I could reproduce the issue with KASAN kernels, between
      10.246.7.151 and 10.246.7.152 :
      
      1) 20 concurrent netperf -t TCP_RR -H 10.246.7.152 -l 1000 &
      
      2) At the same time run following loop :
      while :
      do
       ip ro add 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
       ip ro del 10.246.7.152 dev eth0 src 10.246.7.151 mtu 1500
      done
      
      Cong Wang attempted to add back rt->fi in commit
      82486aa6 ("ipv4: restore rt->fi for reference counting")
      but this proved to add some issues that were complex to solve.
      
      Instead, I suggested to add a refcount to the metrics themselves,
      being a standalone object (in particular, no reference to other objects)
      
      I tried to make this patch as small as possible to ease its backport,
      instead of being super clean. Note that we believe that only ipv4 dst
      need to take care of the metric refcount. But if this is wrong,
      this patch adds the basic infrastructure to extend this to other
      families.
      
      Many thanks to Julian Anastasov for reviewing this patch, and Cong Wang
      for his efforts on this problem.

      ip6_tunnel, ip6_gre: fix setting of DSCP on encapsulated packets · 0e9a7095
      Peter Dawson authored
      This fix addresses two problems in the way the DSCP field is formulated
       on the encapsulating header of IPv6 tunnels.
      Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=195661
      
      1) The IPv6 tunneling code was manipulating the DSCP field of the
       encapsulating packet using the 32b flowlabel. Since the flowlabel is
       only the lower 20b it was incorrect to assume that the upper 12b
       containing the DSCP and ECN fields would remain intact when formulating
       the encapsulating header. This fix handles the 'inherit' and
       'fixed-value' DSCP cases explicitly using the extant dsfield u8 variable.
      
      2) The use of INET_ECN_encapsulate(0, dsfield) in ip6_tnl_xmit was
       incorrect and resulted in the DSCP value always being set to 0.
      
      Commit 90427ef5 ("ipv6: fix flow labels when the traffic class
       is non-0") caused the regression by masking out the flowlabel
       which exposed the incorrect handling of the DSCP portion of the
       flowlabel in ip6_tunnel and ip6_gre.
      
      Fixes: 90427ef5 ("ipv6: fix flow labels when the traffic class is non-0")

      sctp: fix ICMP processing if skb is non-linear · 804ec7eb
      Davide Caratti authored
      sometimes ICMP replies to INIT chunks are ignored by the client, even if
      the encapsulated SCTP headers match an open socket. This happens when the
      ICMP packet is carried by a paged skb: use skb_header_pointer() to read
      packet contents beyond the SCTP header, so that chunk header and initiate
      tag are validated correctly.
      
      v2:
      - don't use skb_header_pointer() to read the transport header, since
        icmp_socket_deliver() already puts these 8 bytes in the linear area.
      - change commit message to make specific reference to INIT chunks.

      net: llc: add lock_sock in llc_ui_bind to avoid a race condition · 0908cf4d
      linzhang authored
      There is a race condition in llc_ui_bind if two or more processes/threads
      try to bind a same socket.
      
      If more processes/threads bind a same socket success that will lead to
      two problems, one is this action is not what we expected, another is
      will lead to kernel in unstable status or oops(in my simple test case,
      cause llc2.ko can't unload).
      
      The current code is test SOCK_ZAPPED bit to avoid a process to
      bind a same socket twice but that is can't avoid more processes/threads
      try to bind a same socket at the same time.
      
      So, add lock_sock in llc_ui_bind like others, such as llc_ui_connect.
