2021-08-11fib: A 16-8-8 and a 8-8-8-8 versions of an ip4_fib_tNeale Ranns1-8/+6
Type: feature The difference being the MTRIE type they contain. THE FIB continues to use the 16-8-8 version. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I5a54d4e6e6cc639f18a3fb65ef2925507a7ef1de
2021-08-09ip6-nd: only respond to RS if sending RA is enabledOle Troan1-1/+6
Even when periodic RAs are disabled VPP would respond to router solicitations. Making it impossible to have an IPv6 enabled interface with hosts connected to it without VPP acting as a default router. This change drops RS messages if the radv_info->send_radv is off.

2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne1-1/+0
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.

2021-04-05ip6-nd: Solicitation reply only if target is our link-localNeale Ranns1-4/+9
Type: fix The fib source IP6_ND is used for all link-local entries, hence solicitation responses were sent for a peer's address. Constrain the source check to also in clude the LOCAL flag, which indicates that the link-local address is ours.

2020-02-26ip-neighbor: fix ip6_ra_cmdDave Barach1-10/+0
The option parsing loop had "break" statements included in each 'if (unformat (line_input, "this-option ...") option_values=xxx;' statement. Result: the code would silently ignore all but the first option. Probably broken forever, not easy to spot because the code looks OK even though it's badly broken.
