2021-03-16fib: Allow the creation of new source on the APINeale Ranns6-20/+201
Type: feature an client can dump the existing sources, examine their priorities, then define thier own source. Usefull if a client wants to distingusih between say, static, ospf, bgp, etc routes it has added over the API.

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>

Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.

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.

2019-11-26fib: Table ReplaceNeale Ranns7-17/+219
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.
