      ip_tunnel: Make vti work with i_key set · 6d608f06
      由 Steffen Klassert 提交于 
      Vti uses the o_key to mark packets that were transmitted or received
by a vti interface. Unfortunately we can't apply different marks
to in and outbound packets with only one key availabe. Vti interfaces
typically use wildcard selectors for vti IPsec policies. On forwarding,
the same output policy will match for both directions. This generates
a loop between the IPsec gateways until the ttl of the packet is
exceeded.

The gre i_key/o_key are usually there to find the right gre tunnel
during a lookup. When vti uses the i_key to mark packets, the tunnel
lookup does not work any more because vti does not use the gre keys
as a hash key for the lookup.

This patch workarounds this my not including the i_key when comupting
the hash for the tunnel lookup in case of vti tunnels.

With this we have separate keys available for the transmitting and
receiving side of the vti interface.

      ipv4: fix a dst leak in tunnels · 6c7e7610
      由 Eric Dumazet 提交于 
      This patch :

1) Remove a dst leak if DST_NOCACHE was set on dst
   Fix this by holding a reference only if dst really cached.

2) Remove a lockdep warning in __tunnel_dst_set()
    This was reported by Cong Wang.

3) Remove usage of a spinlock where xchg() is enough

4) Remove some spurious inline keywords.
   Let compiler decide for us.

      core/dev: do not ignore dmac in dev_forward_skb() · 81b9eab5
      由 Alexei Starovoitov 提交于 
      commit 06a23fe3
("core/dev: set pkt_type after eth_type_trans() in dev_forward_skb()")
and refactoring 64261f23
("dev: move skb_scrub_packet() after eth_type_trans()")

are forcing pkt_type to be PACKET_HOST when skb traverses veth.

which means that ip forwarding will kick in inside netns
even if skb->eth->h_dest != dev->dev_addr

Fix order of eth_type_trans() and skb_scrub_packet() in dev_forward_skb()
and in ip_tunnel_rcv()

      net: Explicitly initialize u64_stats_sync structures for lockdep · 827da44c
      由 John Stultz 提交于 
      In order to enable lockdep on seqcount/seqlock structures, we
must explicitly initialize any locks.

The u64_stats_sync structure, uses a seqcount, and thus we need
to introduce a u64_stats_init() function and use it to initialize
the structure.

This unfortunately adds a lot of fairly trivial initialization code
to a number of drivers. But the benefit of ensuring correctness makes
this worth while.

Because these changes are required for lockdep to be enabled, and the
changes are quite trivial, I've not yet split this patch out into 30-some
separate patches, as I figured it would be better to get the various
maintainers thoughts on how to best merge this change along with
the seqcount lockdep enablement.

Feedback would be appreciated!

      sit: add support of x-netns · 5e6700b3
      由 Nicolas Dichtel 提交于 
      This patch allows to switch the netns when packet is encapsulated or
decapsulated. In other word, the encapsulated packet is received in a netns,
where the lookup is done to find the tunnel. Once the tunnel is found, the
packet is decapsulated and injecting into the corresponding interface which
stands to another netns.

When one of the two netns is removed, the tunnel is destroyed.
