      net: disallow drivers with buggy VLAN accel to register_netdevice() · d2ed273d
      Michał Mirosław authored
      
      
      Instead of jumping aroung bugs that are easily fixed just don't let them in:
      affected drivers should be either fixed or have NETIF_F_HW_VLAN_FILTER
      removed from advertised features.
      
      Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER
      but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features
      are commented out).
      
      OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't
      advertise NETIF_F_HW_VLAN_FILTER. Those are:

      ipv6: add anti-spoofing checks for 6to4 and 6rd · 218774dc
      Hannes Frederic Sowa authored
      
      
      This patch adds anti-spoofing checks in sit.c as specified in RFC3964
      section 5.2 for 6to4 and RFC5969 section 12 for 6rd. I left out the
      checks which could easily be implemented with netfilter.
      
      Specifically this patch adds following logic (based loosely on the
      pseudocode in RFC3964 section 5.2):
      
      if prefix (inner_src_v6) == rd6_prefix (2002::/16 is the default)
              and outer_src_v4 != embedded_ipv4 (inner_src_v6)
                      drop
      if prefix (inner_dst_v6) == rd6_prefix (or 2002::/16 is the default)
              and outer_dst_v4 != embedded_ipv4 (inner_dst_v6)
                      drop
      accept
      
      To accomplish the specified security checks proposed by above RFCs,
      it is still necessary to employ uRPF filters with netfilter. These new
      checks only kick in if the employed addresses are within the 2002::/16 or
      another range specified by the 6rd-prefix (which defaults to 2002::/16).

      in order to eliminate byte holes and achieve compactness.
      Where possible, few members were grouped according to their usage and access

      ip_gre: When TOS is inherited, use configured TOS value for non-IP packets · 040468a0
      David Ward authored
      
      
      A GRE tunnel can be configured so that outgoing tunnel packets inherit
      the value of the TOS field from the inner IP header. In doing so, when
      a non-IP packet is transmitted through the tunnel, the TOS field will
      always be set to 0.
      
      Instead, the user should be able to configure a different TOS value as
      the fallback to use for non-IP packets. This is helpful when the non-IP
      packets are all control packets and should be handled by routers outside
      the tunnel as having Internet Control precedence. One example of this is
      the NHRP packets that control a DMVPN-compatible mGRE tunnel; they are
      encapsulated directly by GRE and do not contain an inner IP header.
      
      Under the existing behavior, the IFLA_GRE_TOS parameter must be set to
      '1' for the TOS value to be inherited. Now, only the least significant
      bit of this parameter must be set to '1', and when a non-IP packet is
      sent through the tunnel, the upper 6 bits of this same parameter will be
      copied into the TOS field. (The ECN bits get masked off as before.)
      
      This behavior is backwards-compatible with existing configurations and
      iproute2 versions.

      ipv4: introduce address lifetime · 5c766d64
      Jiri Pirko authored
      
      
      There are some usecase when lifetime of ipv4 addresses might be helpful.
      For example:
      1) initramfs networkmanager uses a DHCP daemon to learn network
      configuration parameters
      2) initramfs networkmanager addresses, routes and DNS configuration
      3) initramfs networkmanager is requested to stop
      4) initramfs networkmanager stops all daemons including dhclient
      5) there are addresses and routes configured but no daemon running. If
      the system doesn't start networkmanager for some reason, addresses and
      routes will be used forever, which violates RFC 2131.
      
      This patch is essentially a backport of ivp6 address lifetime mechanism
      for ipv4 addresses.
      
      Current "ip" tool supports this without any patch (since it does not
      distinguish between ipv4 and ipv6 addresses in this perspective.
      
      Also, this should be back-compatible with all current netlink users.

      ====================
      This patchset is V2, with some trivial code fixes, which were noticed
      by DaveM. It is still a partly respin of my fragmentation optimization
      patches: http://thread.gmane.org/gmane.linux.network/250914
      
      This is not the complete patchset, from the gmane link above. In this
      patchset, I primarily focus on adjusting cacheline for better SMP/NUMA
      performance.
      
      Once this patchset have been agreed upon, I will continue and respin
      the rest of my patches.
      
      This time around, I have created a frag DoS generator, via the tool
      trafgen (http://netsniff-ng.org/).  To create a stable DoS scenario
      (no longer relying on frame dropping due to disabled flow-control).
      
      Two 10G interfaces are under-test, and uses Ethernet flow-control.  A
      third interface is used for generating the DoS attack (this interface
      is also 10G, but it does not need to be, as 500Kpps DoS is enough).
      
      Test types summary (netperf):
       Test-20G64K     == 2x10G with 65K fragments
       Test-20G3F      == 2x10G with 3x fragments (3*1472 bytes)
       Test-20G64K+DoS == Same as 20G64K with frag DoS
       Test-20G3F+DoS  == Same as 20G3F  with frag DoS

       I cannot explain the under-DoS regression that patch-05/percpu_counter
       introduces.  But patch-06/LRU-lock corrects the situation again.
      
      Below is a testlab setup description, with links to the trafgen DoS
      packet config used.
      
      Testlab
      =======
      
      Server setup
      ------------
      The machine acting as a server:
       - 2x CPU (E5-2630)
       - Thus a NUMA arch/machine
       - 4x 10Gbit/s ports
       - NICs 2x Intel Dual port 82599 based (driver ixgbe)
      
      Setup:
       - Interfaces uses Ethernet flow control
       - Flush all iptables
       - Remove all iptables related module.
       - Kill irqbalance
       - Pin each 10G NIC port to a *single* CPU each
      
      Pinning can easily be done by command hacks::
      
       for x in /proc/irq/*/eth8*/../smp_affinity_list ; do echo 1 > $x; done
       for x in /proc/irq/*/eth9*/../smp_affinity_list ; do echo 3 > $x; done
       for x in /proc/irq/*/eth31*/../smp_affinity_list; do echo 6 > $x; done
       for x in /proc/irq/*/eth32*/../smp_affinity_list; do echo 8 > $x; done
      
      Notice NUMA setting: The CPU to NIC tying is carefully choosen
      according to the NUMA node setup.  Thus, NICs connected to a PCI-e
      slot that is connected to a physical CPU socket are tied together.
      
      Choosing only a single CPU per NIC (port) is just to ease provoking
      and debugging this performance issue. (In real setups, you can choose
      more CPU, just remember the NUMA node in the equation).
      
      Tools
      -----
      
      Netperf is used, with option -T to ensure CPU binding.
      The netserver processes, are NAPI pinned::
      
       numactl -m0 -c0 netserver
       numactl -m1 -c 1 netserver -p 1337
      
      I now have a frag DoS generator, created via the tool:
        trafgen (see: http://netsniff-ng.org/)
      
      Trafgen packet config file:
       http://people.netfilter.org/hawk/frag_work/trafgen/frag_packet03_small_frag.txf
      
      Notice, I'm using features of trafgen, recently developed by Daniel
      Borkmann, thus you need the latest git tree to use my trafgen packet
      config.
      
       git://github.com/borkmann/netsniff-ng.git
      
      
      
      Command line:
       trafgen --dev eth51 --conf frag_packet03_small_frag.txf -V -k 100 --cpus 2

      net: frag, move LRU list maintenance outside of rwlock · 3ef0eb0d
      Jesper Dangaard Brouer authored
      
      
      Updating the fragmentation queues LRU (Least-Recently-Used) list,
      required taking the hash writer lock.  However, the LRU list isn't
      tied to the hash at all, so we can use a separate lock for it.

      net: use lib/percpu_counter API for fragmentation mem accounting · 6d7b857d
      Jesper Dangaard Brouer authored
      
      
      Replace the per network namespace shared atomic "mem" accounting
      variable, in the fragmentation code, with a lib/percpu_counter.
      
      Getting percpu_counter to scale to the fragmentation code usage
      requires some tweaks.
      
      At first view, percpu_counter looks superfast, but it does not
      scale on multi-CPU/NUMA machines, because the default batch size
      is too small, for frag code usage.  Thus, I have adjusted the
      batch size by using __percpu_counter_add() directly, instead of
      percpu_counter_sub() and percpu_counter_add().
      
      The batch size is increased to 130.000, based on the largest 64K
      fragment memory usage.  This does introduce some imprecise
      memory accounting, but its does not need to be strict for this
      use-case.
      
      It is also essential, that the percpu_counter, does not
      share cacheline with other writers, to make this scale.

      net: frag helper functions for mem limit tracking · d433673e
      Jesper Dangaard Brouer authored
      
      
      This change is primarily a preparation to ease the extension of memory
      limit tracking.
      
      The change does reduce the number atomic operation, during freeing of
      a frag queue.  This does introduce a some performance improvement, as
      these atomic operations are at the core of the performance problems
      seen on NUMA systems.

      net: cacheline adjust struct inet_frag_queue · 6e34a8b3
      Jesper Dangaard Brouer authored
      
      
      Fragmentation code cacheline adjusting of struct inet_frag_queue.
      
      Take advantage of the size of struct timer_list, and move all but
      spinlock_t lock, below the timer struct.  On 64-bit 'lru_list',
      'list' and 'refcnt', fits exactly into the next cacheline, and a
      new cacheline starts at 'fragments'.
      
      The netns_frags *net pointer is moved to the end of the struct,
      because its used in a compare, with "next/close-by" elements of
      which this struct is embedded into.

      net: cacheline adjust struct inet_frags for better frag performance · 5f8e1e8b
      Jesper Dangaard Brouer authored
      
      
      The globally shared rwlock, of struct inet_frags, shares
      cacheline with the 'rnd' number, which is used by the hash
      calculations.  Fix this, as this obviously is a bad idea, as
      unnecessary cache-misses will occur when accessing the 'rnd'
      number.
      
      Also small note that, moving function ptr (*match) up in struct,
      is to avoid it lands on the next cacheline (on 64-bit).

      net: cacheline adjust struct netns_frags for better frag performance · cd39a789
      Jesper Dangaard Brouer authored
      
      
      This small cacheline adjustment of struct netns_frags improves
      performance significantly for the fragmentation code.
      
      Struct members 'lru_list' and 'mem' are both hot elements, and it
      hurts performance, due to cacheline bouncing at every call point,
      when they share a cacheline.  Also notice, how mem is placed
      together with 'high_thresh' and 'low_thresh', as they are used in
      the compare operations together.
