2016-05-07VPP-45 Fix crash when GRE packet received on new i/fChris Luke1-0/+3
If a GRE tunnel is created, no other interface added and the GRE tunnel is not set "up" then a crash occurs on the first packet for this tunnel because fib_index_by_sw_if_index[] does not yet have a mapping to the fib the new interface is in. The code to set this is missing from gre/interface.c Change-Id: I567ad74a2af3ea5afe4a40ed39a1d4395642f77c Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-05-06VPP-34 GRE traffic blackholes in encap directionChris Luke1-1/+12
The GRE code is missing the logic to indicate the "hardware" interface is up. The fix is to listen for admin up/down events on the "software" interface and reflect that into the hardware interface state.

2016-05-02VPP-31 Fix linker issue with new sr-replicateChris Luke2-5/+1
Changes in gnu ld in Ubuntu 16.04 tickles an issue with the declaration pattern used for vlib_node_registration when, as is the case in sr_replicate.c, the forward declaration is seen by the linker in a module before the real declaration. This patch uses the "extern" keyword in the forward declaration to avoid this issue and removes extra forward declarations.

2016-04-29Clean up per-thread mheap setup.Dave Barach1-2/+0
The stats thread was sharing the main mheap when we started at least one worker or I/O thread, but ran on its own mheap when we started 0 worker + io threads. Net of this change; if a VLIB_REGISTER_THREAD instance specifies a per-thread mheap, a per-thread mheap will be provided. Otherwise, threads share the main heap. The stats thread now uses the main heap. Simpler is better. Change-Id: I1fff0dd66ae8f7dfe44923f702734e2832b55b09 Signed-off-by: Dave Barach <dbarach@cisco.com>

2016-04-28VXLAN over IPv6.Chris Luke6-166/+628
Refactors the VXLAN node to work with both IPv4 and IPv6 transports. There is a discussion thread for this change at https://lists.fd.io/pipermail/vpp-dev/2016-March/000279.html Note that this changes the binary configuration API to support both address families; each address uses the same memory for either address type and a flag to indicate which is in use. This also includes changes to the Java API to support both address families. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create vxlan tunnel src 192.168.1.1 dst 192.168.1.2 vni 10 encap-vrf-id 0 decap-next l2 IPv6 CLI: create vxlan tunnel src 2620:124:9000::1 dst 2620:124:9000::2 vni 16 encap-vrf-id 0 decap-next l2 IPv4 VAT: vxlan_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 vni 10 encap-vrf-id 0 decap-next l2 IPv6 VAT: vxlan_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 vni 16 encap-vrf-id 0 decap-next l2 TODO: The encap path is not as optimal as it could be.

2016-04-28Track number of ethernet vlans in a frameChris Luke8-7/+83
Adds flags to the packet buffer to track the number of VLANs in the current Ethernet frame. We use two bits to signify 0, 1 or 2 VLANs. The value 3 signififies an unknown quantity of VLANs, which includes "three or more" which is not widely supported. We place the bits in the vlib_buffer section; that is not the opaque section, so that all subordinate nodes can use it. For background, see the discussion thread at https://lists.fd.io/pipermail/vpp-dev/2016-March/000354.html The helper macro ethernet_buffer_header_size(buffer) uses these bits stored in "buffer" to calculate the Ethernet header size. The macro ethernet_buffer_set_vlan_count(buffer, count) sets the appropriate bit values based on the number in "count". By current frame we are referring to the case where a packet that arrives from the wire is carrying an encapsulated Ethernet packet. Once decapsulated that inner packet becomes the current frame. There are two places where this value is set; For most Ethernet frames this will be in the "ethernet-input" node when that node parses the Ethernet header. The second place is whenever vnet_update_l2_len() is used to update the layer 2 opaque data. Typically this function is used by nodes just before they send a packet into l2-input. These bits are zeroed in vlib_buffer_init_for_free_list() meaning that wherever the buffer comes from they have a reasonable value (eg, if ip4/ip6 generates the packet.) Primarily this VLAN counter is used by nodes below "ethernet- input" and "l2-input" to determine where the start of the current Ethernet header is. There is opaque data set by "ethernet-input" storing the offset of the current Ethernet header but, since this is opaque, it's not usable by downstream nodes. Previously several nodes have made assumptions regarding the location of the Ethernet header, including that it is always at the start of the packet buffer (incorrect when we have encapsulated packets) or that it is exactly sizeof(ethernet_header_t) away (incorrect when we have VLAN tags.) One notable case where this functionality is required is in ip6_neighbor when it generates a response to a received neighbor soliciation request; it reuses the incoming Ethernet header in-situ and thus needs to reliably know where that header begins. Also, at the suggestion of Dave Barach, this patch removes definition of HGSHM bits in the buffer flags since they are unused and unlikely to ever be.

This patch introduces standard command line 'set interface mtu' for setting the MTU for tap devices. It allows user to set the mtu in between 68 to 65535 bytes aligned to what linux kernel supports for tun/tap devices. Right now tapcli set the same MTU size for each tap interface.
