2021-09-27fib: fix crash on exporter tracker removeVladislav Grishenko1-4/+3
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.

2021-06-17fib: changing parsing order to avoid corner caseArthur de Kerhor1-3/+3
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.

In the forwarding plane the MTU is enfored either: 1 - if the peer is attached, then the MTU is set on the peer's adjacency 2 - if the peer is not attached, it is remote, then a DPO is added to the peer's FIB entry to perform the necessary fragmentation.

2020-07-06fib: fix debug preprocessor directivesMatthew Smith4-4/+4
Type: fix Some debugging declarations were wrapped in an 'ifdef CLIB_DEBUG'. This seems to always evaluate true because clib.h defines CLIB_DEBUG to 0 if its not defined. The result is that if a route table is added and a route is added to it and then the table is deleted, VPP exits because the debug function fib_table_assert_empty() gets called whether VPP was started using a debug build or a release build. Change the ifdef to 'if CLIB_DEBUG > 0'. Change-Id: I357dc2c299e81b95244f2f7efaadb8e0de27627a Signed-off-by: Matthew Smith <mgsmith@netgate.com>
