      ipv6: addrconf: silence sparse endianness warnings · bc861959
      Bjørn Mork authored
      Avoid the following sparse __CHECK_ENDIAN__ warnings:
      
       include/net/addrconf.h:318:25: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:318:70: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:330:25: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:330:70: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:347:25: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:348:26: warning: restricted __be64 degrades to integer
       include/net/addrconf.h:349:18: warning: restricted __be64 degrades to integer
      
      The warnings are false but they make it harder to spot real
      bugs.

      ====================
      This is the rework of the IPsec virtual tunnel interface
      for ipv4 to support inter address family tunneling and
      namespace crossing. The only change to the last RFC version
      is a compile fix for an odd configuration where CONFIG_XFRM
      is set but CONFIG_INET is not set.
      
      1) Add and use a IPsec protocol multiplexer.
      
      2) Add xfrm_tunnel_skb_cb to the skb common buffer
         to store a receive callback there.
      
      3) Make vti work with i_key set by not including the i_key
         when comupting the hash for the tunnel lookup in case of
         vti tunnels.
      
      4) Update ip_vti to use it's own receive hook.
      
      5) Remove xfrm_tunnel_notifier, this is replaced by the IPsec
         protocol multiplexer.
      
      6) We need to be protocol family indepenent, so use the on xfrm_lookup
         returned dst_entry instead of the ipv4 rtable in vti_tunnel_xmit().
      
      7) Add support for inter address family tunneling.
      
      8) Check if the tunnel endpoints of the xfrm state and the vti interface
         are matching and return an error otherwise.
      
      8) Enable namespace crossing tor vti devices.

      Merge branch 'kdoc' · e1fbf260

      ====================
      net: start kdoc'ifying net_device
      
      While working on extending some functionality I felt restricted
      with the amount of documentation I can add. Part of this is that
      the existing style on the header files don't let me be verbose.
      This starts addressing that by using kdoc for the net_device
      flags, and as Ben noted, the priv_flags can be moved out from
      UAPI.

      These are private to userspace, and they're unstable
      anyway and can be shuffled at will (see 080e4130)
      so any userspace application relying on them is on crack.

      net: kdoc struct net_device flags and priv_flags · 589f5816
      Luis R. Rodriguez authored
      We have documentation for these flags but they're scattered
      all over the place. #defines don't allow documentation to be
      written easily so to help to start bringing some documentation
      together use the enums kdoc practice but keep the defines to
      allow userspace to be able to #ifdef them.
      
      I've verified the same values are assigned before and after
      with a simple userspace test program [0] and checksumming the
      output.

      atm: nicstar: remove interruptible_sleep_on_timeout · 118ce7ab
      Arnd Bergmann authored
      We are trying to finally kill off interruptible_sleep_on_timeout.
      the two uses in the nicstar driver can be trivially replaced
      with wait_event_interruptible_lock_irq_timeout, which prevents the
      wake-up race and is able to check the buffer state with scq->lock
      held.
