2017-05-17ARP learning fixes (VPP-843)Neale Ranns1-2/+6
learn ARP peers if, 1) it's a reply to a local address, 2) we are sending a response to a request. send proxy ARP responses only in the interface the request was sent. Change-Id: I22b949c65122824233076492b7dd537daca07bc2 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-04-24Improve Load-Balance MAPsNeale Ranns1-1/+1
- 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>

2017-04-07MPLS McastNeale Ranns1-0/+1
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.

2017-04-06Use thread local storage for thread indexDamjan Marion1-2/+2
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.

bridging. That is hosts in one sub-net reachable via differenet interfaces. Introducate a new API command: ip6 nd proxy <host-address> <interface> this indicates 2 things; 1) that host <host-address> is reachable out of interface <interface>. VPP will thus install that route. 2) NS requests sent to <host-address> will be responeded to (i.e. proxied).

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-6/+21
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-63/+71
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
