2021-06-09fib: make sure dpo is valid even when path pool expandsBenoît Ganne1-8/+22
The path pool can expand during in fib_path_attached_next_hop_get_adj() when calling adj_nbr_add_or_lock(). If dpo points to a path->fp_dpo, its reference becomes stale. Use a temporary copy instead.

2021-02-15ip: Path MTUNeale Ranns3-2/+25
Type: feature Support setting the MTU for a peer on an interface. The minimum value of the path and interface MTU is used at forwarding time. the path MTU is specified for a given peer, by address and table-ID. 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.

2021-02-11tests: tag the tests that do not work with multi-worker configurationAndrew Yourtchenko1-0/+2
If the multi-worker default VPP configuration is triggered by setting VPP_WORKER_CONFIG="workers 2", some of the tests fail for various reasons. It's a substantial number, so this change marks all of the testsets that have this issue, such that they can be addressed later independently.

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>

2020-01-22fib: FIB crash removing labelled route (VPP-1818)Neale Ranns1-7/+12
Type: fix The crash occured trying to retreive a NULL path list to walk the path extensions. A walk shoul not be required, because there should be no extensins, since all paths are removed. The problem is that when the paths were added, they were not sorted, hence neither were the extensions and when they were updated, duplicate extensions were added, and hence a path removal did not remove them all. Fix is to make sure paths are sorted.
