Type: fix Ticket: VPP-1970 Ticket: VPP-1992 Fixes: 9e17887db97bb9f6507270f9fa9923c10816e0df https://gerrit.fd.io/r/c/vpp/+/33495/7 introduced a bug where ND responses are inproperly dropped. This fixes that bug. Signed-off-by: Ed Warnicke <hagbard@gmail.com> Change-Id: Iec4b07646332ced292e2211408c4f7af3088ac28 Signed-off-by: Ed Warnicke <hagbard@gmail.com>
2021-10-07arp: source address selectionEd Warnicke1-2/+5
https://gerrit.fd.io/r/c/vpp/+/30197 introduced SAS and inadvertently broke ping in a variety of situations: https://jira.fd.io/browse/VPP-1992 https://jira.fd.io/browse/VPP-1970 https://lists.fd.io/g/vpp-dev/topic/84038840 all of which seem to be rooted in situations where there's literally nothing smarter ping can do for source address selection than to pick the first IP on the interface. This can happen for: 1. P2P interfaces, see attempted fix: https://gerrit.fd.io/r/c/vpp/+/32801 2. Interfaces with /32 IP addresses intentionally assigned After some discussion, this problem was partially fixed in https://gerrit.fd.io/r/c/vpp/+/33449 Unforunately, while source selection was fixed in ping, it continued to be broken in arp/nd. This gerrit builds on https://gerrit.fd.io/r/c/vpp/+/33449 and fixes arp/nd.

2021-04-02ip-neighbor: suppress unsolicited clib_warning when sending garpSteven Luong1-3/+9
Replace clib_warning with vlog_log_debug when sending garp. There is nothing to alert/warn the operator about sending garp. vlib_log is more appropriate. Type: fix Signed-off-by: Steven Luong <sluong@cisco.com> Change-Id: Ib88a2b46d2ab8b3c35162538ead0dd0983fb7093
2020-12-08fib: Source Address SelectionNeale Ranns1-13/+9
Type: feature Use the FIB to provide SAS (in so far as it is today) - Use the glean adjacency as the record of the connected prefixes = there's a glean per-{interface, protocol, connected-prefix} - Keep the glean up to date with whatever the recieve host prefix is (since it can change) Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Change-Id: I0f3dd1edb1f3fc965af1c7c586709028eb9cdeac

2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-0/+338
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.
