2017-04-24Debug CLI to magically create / delete a TCP sessionDave Barach4-55/+127
The session ends up in established state, and is hand-crafted to look like it was created by the builtin_server. This will come in handy for injecting packets into tcp46-established, along with ancillary debug CLI to adjust connection parameters. Immediate applications include screwball window cases, out of order segments, paws checking, and so on and so forth. Debug CLI script: loop create set int ip address loop0 6.0.1.1/8 set int state loop0 up set ip arp loop0 6.0.1.2 feed.face.babe test tcp server test tcp session packet-generator new { name tcp limit 1 node ip4-input size 100-100 interface loop0 no-recycle data { TCP: 6.0.1.2 -> 6.0.1.1 TCP: 11234 -> 1234 ACK window 2000 seqnum 0 acknum 0 incrementing 100 } } Change-Id: I866c2159376064b7d14f70531022c1fe949258c2 Signed-off-by: Dave Barach <dave@barachs.net>
2017-04-24Improve Load-Balance MAPsNeale Ranns16-199/+571
- only build them for popular path-lists (where popular means more than 64 children) the reason to have a map is to improve convergence speed for recursive prefixes - if there are only a few this technique is not needed - only build them when there is at least one path that has recursive constraints, i.e. a path that can 'fail' in a PIC scenario. - Use the MAPS in the switch path. - PIC test cases for functionality (not convergence performance) Change-Id: I70705444c8469d22b07ae34be82cfb6a01358e10 Signed-off-by: Neale Ranns <nranns@cisco.com>

* Populated the trace struct that weren't used before * Modified and created format functions to format tcp packets and connections * Completed the node definitions to add the format_trace function * Filled the tracing parts with `vlib_add_trace' calls in each tcp node function For the nodes in tcp_input.c, there is a verbose trace and a non-verbose trace. Each packet goes through tcp[4-6]-input which is traced with `format_tcp_rx_trace', and the other nodes are traced with `format_tcp_rx_trace_short'.

2017-04-11Devices: set interface placement does not remove the old interface placementSteven1-3/+0
The command set interface placement is supposed to remove the existing interface placement and add a new interface placement based on the given options. My quick test for the CLI shows that the old interface placement continues to exist. But the new interface placement is also added. The bug exists in vnet_device_input_unassign_thread which checks the old thread index is the same as the passed thread index and skips the deletion if they are the same. The fix is to remove the check which is not supposed to be there. Change-Id: Ib055721fad47513949a03b3cb6dc292bd19fd1e8 Signed-off-by: Steven <sluong@cisco.com>

1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

2017-04-06BFD-FIB interactionsNeale Ranns21-144/+1550
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

2017-04-06Use thread local storage for thread indexDamjan Marion63-453/+470
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-04-05GRE over IPv6Ciara Loftus6-177/+545
Refactors the GRE node to work with both IPv4 and IPv6 transports. 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. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create gre tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 CLI: create gre tunnel src 2620:124:9000::1 dst 2620:124:9000::2 IPv4 VAT: gre_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 VAT: gre_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 Change-Id: Ica8ee775dc101047fb8cd41617ddc8fafc2741b0 Signed-off-by: Ciara Loftus <ciara.loftus@intel.com>
