2021-12-21fib: MPLS EOS chains built for attached prefixes should link to a lookup DPONeale Ranns7-61/+51
Type: fix Presently a local label associated with an attached or connected prefix will link to the glean. This is a problem since it will never use the adj-fibs that are installed for that attached prefix. Instead link the local label to a lookup in the table in which the attached link is bound.

Type: fix re-evaluate the import/export state of a prefix when the interface it is attached to rebinds to a different table. Only attached routes have import/export requirements, so we can back walk from the glean adjacency when the interface rebinds tables. There are two cases to consider. 1. the rebind may change the prefix from/to import 2. the import VRF may change Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I25b6af43b3b2d8f701dfbe7a08710dc56b3f5778

Type: fix If the walk is triggered when the child is added, then that child is visited in the walk. However, since it is just attahcing to the path-list it may not, or indeed cannot, have all the context it needs to successfully handle the walk. In the case of MPLS tunnel, it does not have the path extensions ready, and cannot since the path extensions need to resolve on the path-list.

2021-10-11ip: fix fib and mfib locksNathan Skrzypczak1-2/+39
This patches fixes an issue that could cause fib locks to underflow: if an API user deletes a fib and quickly recreates it, the fib may not have been actually deleted. As a result, the lock would not be incremented on the create call leading to the fib potentially disappearing afterwards - or to the lock to underflow when the fib is deleted again. In order to keep the existing API semantics, we use the locks with API and CLI source as flags. This means we need to use a different counter for the interface-related locks. This also prevents an issue where an interface being bound to a vrf via API and released via CLI could mess up the lock counter. Finally, this will help with cleaning up the interface-related locks on interface deletion in a later patch.

Exported entries are tracked only when the prefix found in the export FIB is really attached, exporter tracker is not set if the export entry is not valid for export, ex. for special FIB entries - default route, zeronet, mcast and broadcast prefixes. When imported entries need to be purged, such unset exporter tracker is being removed by non-initialized index with absent delegate entries, causing corresponding assert and crash.

mfib interface flags are parsed before the interface name. For some specific names, this creates a bug when adding routes. ex: ip route add 10.0.2.0/24 via FortyGigabitEthernetd8/0/0 The 'F' at the beginnig of the interface name is parsed as the "Forward" flag. Because of that, the interface name parsed is "ortyGigabitEthernetd8/0/0" which results in a parsing error.
