- IPv6 link local table is a per-SW interface array of IPv6 unicast FIBs
- the per-interface ocst is sizeof(fib_table_t) which is small,
w.r.t. the cost of an interface
- FE80::/10 in the 'global' table points to a DPO that performs a lookup in the
input interface's LL fib.

part 2;
- this adds the code to create an IP and MPLS table via the API.
- but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass.

To save space in the first cacheline following is changed:
- total_length_not_including_first_buffer moved to the 2nd cacheline.
This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and
VLIB_BUFFER_NEXT_PRESENT are both set.
- free_list_index is now stored in 4bits inside flags, which
allows up to 16 free lists. In case we need more we can store index
in the 2nd cachelin

If a bonded interface is in active-backup mode and configured with
IPv4 and/or IPv6 addresses, on slave interface link up/down, send
a GARP packet if configured with an IPv4 address and an unsolcited
NA if configured with an IPv6 address. These packets can help with
faster route convergence in the next hop router/switch.

there are, intentionally, no validation checks in the ARP/ND code to prevent an ARP/ND entry from being installed for an address that is not local to the interface's sub-net. This is ok, since the adjacency/FIB code is designed to handle this case using the 'refinement' criteria - i.e. only installing a FIB entry for the address if the address 'refines' (i.e. is more specific than) the interface's sub-net.
However, the refinement criteria currently operates on the FIB entry's prefix (which is a /32, so on the address) and not on the next-hop in the path.
So, enter multiple ARP entries for the same address on different links, and this refinement criteria uses only the last added path, and so will remove the FIB entry should the ARP entries be added in the 'wrong' order.
This fix updates the refinement criteria to work on each path of the FIB entry. The entry is installed if one of the paths refines the covers and only paths refining the cover contribute forwarding.
Per-path refinement checks are stored in path-extensions. The patch is rather large as path-extension, which were previously used only for out-going MPLS labels, have been generalized.

- 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)

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.

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).

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.

- 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.
