Type: feature - ip-neighbour: generic neighbour handling; APIs, DBs, event handling, aging - arp: ARP protocol implementation - ip6-nd; IPv6 neighbor discovery implementation; separate ND, MLD, RA - ip6-link; manage link-local addresses - l2-arp-term; events separated from IP neighbours, since they are not the same. vnet retains just enough education to perform ND/ARP packet construction. arp and ip6-nd to be moved to plugins soon.

2019-11-26fib: Table ReplaceNeale Ranns1-1/+131
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

Type: fix if the packet is about to be fragmented, then don't call any of the actions that expect the rewrite to have been written. 1) don't double count packets thru the adjacency (original & fragments) 2) don't double decrement the TTL for fragments 3) return to ip4-midchain post ip-frag if that's where we started. 4) only run midchain/mcast fixups if not fragmenting (if no errors) Change-Id: Ib2866787a42713ee5871b87b597d8f74b901044b Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-08-12ip: allow addrs from the same prefix on intfMatthew Smith1-6/+59
Type: feature Adding a prefix to an interface was not permitted if it overlapped with another prefix on an interface which used the same FIB. Loosen the restriction. Allow 2 or more addresses from the same prefix on a single interface. Reference count the prefix to figure out when a glean/connected route for the prefix needs to be added or removed. Added unit tests to check that the route is only removed when all addresses in the prefix are removed from the interface.

2019-06-18fib: fib api updatesNeale Ranns1-132/+69
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>
