2022-11-06ip6-nd: set router flag on NA if appropriateMatthew Smith3-1/+19
Type: fix The router flag on a neighbor advertisement can be used by neighbors to detect that a router has changed to a host (RFC 4861 section 4.4). If a neighbor adds routes after receiving a router advertisement sent by VPP and subsequently receives a neighbor advertisement sent by VPP, it may remove any routes it added based on the RA if the NA does not have the router flag set. It appears that this is how windows behaves. When sending a neighbor advertisement, set the router flag if sending RAs is enabled on the interface.

2022-11-05ip6-nd: initialize radv_info->send_radv to 1Dave Barach1-0/+3
Otherwise, the newly configured interface will never send RADV's. See below. In the typical case, suppress = 0 and is_no = 0, which propagates the current value of radv->send_radv: radv_info->send_radv = (suppress != 0) ? ((is_no != 0) ? 1 : 0) : radv_info->send_radv; No other bit of code will set send_radv, at least in straightforward ways.

2022-03-24ip6-nd: stop sending RA by defaultAlexander Chernavin1-3/+0
Type: improvement Currently, RA message sending is enabled by default - both periodic and in response to RS message. However, RFC 4861 section 6.2.1 says the following: Note that AdvSendAdvertisements MUST be FALSE by default so that a node will not accidentally start acting as a router unless it is explicitly configured by system management to send Router Advertisements. With this change, RA message sending is disabled by default and "test_ip6.TestIPv6.test_rs" updated appropriately.

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.
