      net: ipv6: add NLM_F_APPEND in notifications when applicable · 1f5e29ce
      David Ahern 提交于
      IPv6 does not set the NLM_F_APPEND flag in notifications to signal that
      a NEWROUTE is an append versus a new route or a replaced one. Add the
      flag if the request has it.

      net: ethernet: ti: cpsw: fix NULL pointer dereference in switch mode · f6961862
      Grygorii Strashko 提交于
      In switch mode on struct cpsw_slave->ndev field will be initialized with
      proper value only for the one cpsw slave port, as result
      cpsw_get_usage_count() will generate "Unable to handle kernel NULL pointer
      dereference" exception when first ethernet interface is opening
      cpsw_ndo_open(). This issue causes boot regression on AM335x EVM and
      reproducible on am57xx-evm (switch mode).
      Fix it by adding additional check for !cpsw->slaves[i].ndev in
      cpsw_get_usage_count().

      net: reduce skb_warn_bad_offload() noise · b2504a5d
      Eric Dumazet 提交于
      Dmitry reported warnings occurring in __skb_gso_segment() [1]
      
      All SKB_GSO_DODGY producers can allow user space to feed
      packets that trigger the current check.
      
      We could prevent them from doing so, rejecting packets, but
      this might add regressions to existing programs.
      
      It turns out our SKB_GSO_DODGY handlers properly set up checksum
      information that is needed anyway when packets needs to be segmented.
      
      By checking again skb_needs_check() after skb_mac_gso_segment(),
      we should remove these pesky warnings, at a very minor cost.
      
      With help from Willem de Bruijn

      rtnetlink: Handle IFLA_MASTER parameter when processing rtnl_newlink · 160ca014
      Theuns Verwoerd 提交于
      Allow a master interface to be specified as one of the parameters when
      creating a new interface via rtnl_newlink.  Previously this would
      require invoking interface creation, waiting for it to complete, and
      then separately binding that new interface to a master.
      
      In particular, this is used when creating a macvlan child interface for
      VRRP in a VRF configuration, allowing the interface creator to specify
      directly what master interface should be inherited by the child,
      without having to deal with asynchronous complications and potential
      race conditions.

      ====================
      pull request (net-next): ipsec-next 2017-02-01
      
      1) Some typo fixes, from Alexander Alemayhu.
      
      2) Don't acquire state lock in get_mtu functions.
         The only rece against a dead state does not matter.
         From Florian Westphal.
      
      3) Remove xfrm4_state_fini, it is unused for more than
         10 years. From Florian Westphal.
      
      4) Various rcu usage improvements. From Florian Westphal.
      
      5) Properly handle crypto arrors in ah4/ah6.
         From Gilad Ben-Yossef.
      
      6) Try to avoid skb linearization in esp4 and esp6.
      
      7) The esp trailer is now set up in different places,
         add a helper for this.
      
      8) With the upcomming usage of gro_cells in IPsec,
         a gro merged skb can have a secpath. Drop it
         before freeing or reusing the skb.
      
      9) Add a xfrm dummy network device for napi. With
         this we can use gro_cells from within xfrm,
         it allows IPsec GRO without impact on the generic
         networking code.
      
      Please pull or let me know if there are problems.
