Type: improvement the existing mtrie functions use the existing 16_8_8 mtrie. Rename them to make that explicit. Then we can add the 8_8_8_8 types and functions alongside. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If5ce7a282d5d3742dc65bcd0523220235d9c510d

2020-07-06fib: fix debug preprocessor directivesMatthew Smith1-1/+1
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>
2020-02-11vppinfra: remove the historical mheap memory allocatorDave Barach1-12/+3

2019-12-04fib: Decouple source from priority and behaviourNeale Ranns1-3/+6
Type: feature the fib_source_t enum alone no longer defines the priority and behaviour, instead each source must be allocated these attributes. This allows the creation of other sources by the plugins (and soon over the API). Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I890ee820fbc16079ee417ea1fbc163192806e853
2019-11-26fib: Table ReplaceNeale Ranns1-2/+4
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.

2017-04-26IP Flow Hash Config fixesNeale Ranns1-10/+2
- the flow hash config is (and was) cached on the load-balance object so the fib_table_t struct is not used a switch time. Therefore changes to the table's flow hash config need to be propagated to all load-balances and hance all FIB entries in the table. - enable API for setting the IPv6 table flow hash config - use only the hash config in the fib_table_t object and not on the ipX_fib_t - add tests.

2017-04-06BFD-FIB interactionsNeale Ranns1-4/+12
- single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).

2017-04-01MTRIE Optimisations 2Neale Ranns1-15/+45
1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.

2017-03-29Mtrie optimisationsNeale Ranns1-1/+2
1 - make the default route non-special, i.e. like any other less specific route. Consequently, all buckets have a valid valid index of either a leaf or a ply. Checks for special indeices in the data-path can thus be removed. 2 - since all leaves are now 'real' i.e. they represent a real load-balance object, to tell if a ply slot is 'empty' requeirs chekcing that the prefix length of the leaf occupying the slot is slot than the minium value for that ply. 3 - when removing a leaf find the cover first, then recurse down the ply and replace the old leaf with the cover. This saves us a ply walk. Change-Id: Idd523019e8bb1b6ef527b1f5279a5e24bcf18332 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-01-27IP Multicast FIB (mfib)Neale Ranns1-11/+39
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
