      ipv6: do not clear pinet6 field · f77d6021
      Eric Dumazet authored
      We have seen multiple NULL dereferences in __inet6_lookup_established()
      
      After analysis, I found that inet6_sk() could be NULL while the
      check for sk_family == AF_INET6 was true.
      
      Bug was added in linux-2.6.29 when RCU lookups were introduced in UDP
      and TCP stacks.
      
      Once an IPv6 socket, using SLAB_DESTROY_BY_RCU is inserted in a hash
      table, we no longer can clear pinet6 field.
      
      This patch extends logic used in commit fcbdf09d
      ("net: fix nulls list corruptions in sk_prot_alloc")
      
      TCP/UDP/UDPLite IPv6 protocols provide their own .clear_sk() method
      to make sure we do not clear pinet6 field.
      
      At socket clone phase, we do not really care, as cloning the parent (non
      NULL) pinet6 is not adding a fatal race.

      macvlan: fix passthru mode race between dev removal and rx path · 233c7df0
      Jiri Pirko authored
      Currently, if macvlan in passthru mode is created and data are rxed and
      you remove this device, following panic happens:
      
      NULL pointer dereference at 0000000000000198
      IP: [<ffffffffa0196058>] macvlan_handle_frame+0x153/0x1f7 [macvlan]
      
      I'm using following script to trigger this:
      <script>
      while [ 1 ]
      do
      	ip link add link e1 name macvtap0 type macvtap mode passthru
      	ip link set e1 up
      	ip link set macvtap0 up
      	IFINDEX=`ip link |grep macvtap0 | cut -f 1 -d ':'`
      	cat /dev/tap$IFINDEX  >/dev/null &
      	ip link del dev macvtap0
      done
      </script>
      
      I run this script while "ping -f" is running on another machine to send
      packets to e1 rx.
      
      Reason of the panic is that list_first_entry() is blindly called in
      macvlan_handle_frame() even if the list was empty. vlan is set to
      incorrect pointer which leads to the crash.
      
      I'm fixing this by protecting port->vlans list by rcu and by preventing
      from getting incorrect pointer in case the list is empty.

      Rony Efraim authored
      Make sure that the following steps are taken:
      
      - drop packets sent by the VF with vlan tag
      - block packets with vlan tag which are steered to the VF
      - drop/block tagged packets when the policy is priority-tagged
      - make sure VLAN stripping for received packets is set
      - make sure force UP bit for the VF QP is set
      
      Use enum values for all the above instead of numerical bit offsets.

      missed reporting in the device capabilities dump when these features

      net: fec: enable hardware checksum only on imx6q-fec · 48496255
      Shawn Guo authored
      Commit 4c09eed9 (net: fec: Enable imx6 enet checksum acceleration.)
      enables hardware checksum acceleration unconditionally for all fec
      variants.  This is inappropriate, because some variants like imx5 have
      no such support on hardware.  Consequently, fec is broken on these
      platforms.  Fix it by enabling hardware checksum only on imx6q-fec type
      of controllers.

      Pull trivial pstore update from Tony Luck:
       "Couple of pstore cleanups"
      
      It turns out that the kmemdup() conversion ends up being undone by the
      fact that the memory block also needed the ecc information (see commit
      bd08ec33: "pstore/ram: Restore ecc information block"), so all that
      remains after merging is the error return code change.

        on the extent allocation tree format.  btrfstune -x enables them, and
        the new format makes the extent allocation tree about 30% smaller.
      
        I rebased this a few days ago to rework Dave Sterba's crc checks on
        the super block, but almost all of these go back to rc6, since I
        though 3.9 was due any minute.
      
        The biggest missing fix is the tracepoint bug that was hit late in
        3.9.  I ran into problems with that in overnight testing and I'm still
        tracking it down.  I'll definitely have that fixed for rc2."
