bgpd: modify path selection for EVPN type-5 routes
|
| | |
| |
| |
| |
| |
| |
| |
| |
| |
| |
| | |
For EVPN routes, there is specific logic in place for path selection
surrounding MAC Mobility. For pure type-5 routes, if a route is
advertised with a MED, this is ignored since it ultimately falls inside
of the EVPN specific path selection logic, and ultimately selects the
lower IP address. This change ensures only type-2 routes fall into the
EVPN BGP path selection.

This bit of code was cut-n-pasted all over the place:
if (!bpa->installed && !bpa->install_in_progress) {
bgp_send_pbr_rule_action(bpa, NULL, true);
bgp_zebra_announce_default(bgp, nh,
bpa->afi,
bpa->table_id, true);

Create a function bgp_bpr_bpa_remove that is this cut-n-paste code:
if (bpa->refcnt == 0) {
if (bpa->installed && bpa->table_id != 0) {
bgp_send_pbr_rule_action(bpa, NULL, false);
bgp_zebra_announce_default(bpa->bgp, &(bpa->nh),
AFI_IP,
bpa->table_id,
false);
bpa->installed = false;

Fix #8567 OSPFv3-26.13 ANVL failure
|

| | | | | | |
Fixes OSPFv3-26.13 ANVL RFC conformance bug #8576 by improving the bugfix
for #7030 from 4c63a76a. That commit changed handling of received old
non-MAXAGE LSAs with a MAXAGE counterpart in the LSDB from "add all LSAs to
LSDB and flood non-self-originated ones" to "add & flood only
non-self-originated LSAs and ignore self-originated LSAs". The new behaviour
is similar but adds sending a MAXAGE LS Update for received self-originated
LSAs to remove the old LSAs from the network, resulting in "add & flood
non-self-originated LSAs, don't add but send MAXAGE LS Update for
self-originated LSAs". The missing MAXAGE LS Update is what OSPFv3-26.13
ANVL complained about.

lib,zebra: Use a flag to track down status for connected addrs

| | | | | | | | |
Track 'down' state of connected addresses with a new flag. We
may have multiple addresses on an interface that share a prefix;
in those cases, we need to determine when the first address
is valid, to install a connected route, and similarly detect
when the last address goes 'down', to remove the connected
route.

bgpd: fix deconfig of conditional advertisement

Deconfiguring conditional advertisement resulted in all other policy
settings on the peer getting removed due to an excessively large memset.
This also created a desync with the northbound config tree, which caused
its own set of problems...
Fix the memset to just remove the conditional advertisement config.

In order to parse the netlink message into the
`struct rtattr *tb[size]` it is assumed that the buffer is
memset to 0 before the parsing. As such if you attempt
to read a value that was not returned in the message
you will not crash when you test for it.
The code has places were we memset it and places where we don't.
This *will* lead to crashes when the kernel changes. In
our parsing routines let's have them memset instead of having
to remember to do it pre pass in to the parser.

The code had no limits on addresses configured on an interface running
ospf6d. The code would crash when more than 100 addresses were added.
This change limits the number of interface address to 100 if mtu is set
to the default value. If the mtu is set to a jumbo packet size or larger
we will support 200 interface addresses.
