2017-09-11FIB table add/delete APINeale Ranns1-2/+3
part 2; - this adds the code to create an IP and MPLS table via the API. - but the enforcement that the table must be created before it is used is still missing, this is so that CSIT can pass. Change-Id: Id124d884ade6cb7da947225200e3bb193454c555 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach1-1/+1
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.

2017-05-24IPv6 Performance bugsNeale Ranns1-3/+39
- inline the FIB lookup function; this requires access to the bihash, so for files that use more than one type this casues problems. those files that include ip6_fib.h unnecessarily have been updated - better use of the feature arcs. ip6-lookup and interface-output are now sentinels (end-node-index in the cm speak) rather than enabled features.

2017-04-26IP Flow Hash Config fixesNeale Ranns1-2/+0
- 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.

2017-04-01MTRIE Optimisations 2Neale Ranns1-1/+1
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.

2017-02-13Out-of-tree Build Error fixAkshayaNadahalli1-22/+0
File vnet/fib/fib_urpf_list.h was included in vnet/fib/ip6_fib.h but was exported to be installed in /usr/include/vnet. So out-of-tree builds relying on an installed package was failing. Fix is to inlcude fib_urpf_list.h in source file rather than including it in header file. Change-Id: Iae39c1d9417dbd31ee67fa1bd2d1915d5e813c73 Signed-off-by: AkshayaNadahalli <anadahal@cisco.com>
2017-02-08Fix source address reachability check for ip6 local packetsAkshayaNadahalli1-1/+23
Currently ip6 local check fails with error - source lookup miss if route to source of packet is over a dpo object such as load balance - recurssive route, tunnel adj - GRE, SR etc. So unless packet source is of a directly connected neibhor or has route with both interface and nexthop specified, it will be dropped. Fix is to check urpf list and if at least one link exists in the list, then allow packets to be processed, else drop.

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-1/+10
- 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.
