2023-08-29mpls: add mpls_interface_dumpPim van Pelt1-0/+48
Add an API call mpls_interface_dump() which returns a list of mpls_interface_details: - If no sw_if_index is given, all MPLS enabled sw_if_index are returned. - If a particular sw_if_index is given, and it doesn't exist, an empty list is returned. - If a sw_if_index exists and has MPLS enabled, a list of that one sw_if_index is returned. Tested: - Create 3 loopback interfaces - Call for ~0 and for sw_if_index 0..5 all return empty lists - set int mpls loop0 enable - set int mpls loop1 enable - Call for ~0 returns 2, and the call for sw_if_index=1 and =2 (the loopbacks) returns each a list of one sw_if_index 1 resp 2, the other values of sw_if_index return empty list - set int mpls loop0 disable - Call for ~0 returns 1, and the call for sw_if_index=2 (loop1) returns both a list of one sw_if_index=2, the other values of sw_if_index return empty list - set int mpls loop1 disable - Call for ~0 and for sw_if_index 0..5 all return empty lists Example Python3 API program: ``` api_response = vpp.api.mpls_interface_dump() print(f"Response is {api_response}") for i in [ 0, 1, 2, 3, 4, 5 ]: api_response = vpp.api.mpls_interface_dump(sw_if_index=i) print(f"Response[{i}] = {api_response}") ``` Type: improvement Change-Id: If87f7d7f8972d99260e859757dbcb251c6fa54a8 Signed-off-by: Pim van Pelt <pim@ipng.nl>

2021-10-11ip: fix fib and mfib locksNathan Skrzypczak1-10/+2
This patches fixes an issue that could cause fib locks to underflow: if an API user deletes a fib and quickly recreates it, the fib may not have been actually deleted. As a result, the lock would not be incremented on the create call leading to the fib potentially disappearing afterwards - or to the lock to underflow when the fib is deleted again. In order to keep the existing API semantics, we use the locks with API and CLI source as flags. This means we need to use a different counter for the interface-related locks. This also prevents an issue where an interface being bound to a vrf via API and released via CLI could mess up the lock counter. Finally, this will help with cleaning up the interface-related locks on interface deletion in a later patch.

2019-06-18fib: fib api updatesNeale Ranns1-201/+151
Enhance the route add/del APIs to take a set of paths rather than just one. Most unicast routing protocols calcualte all the available paths in one run of the algorithm so updating all the paths at once is beneficial for the client. two knobs control the behaviour: is_multipath - if set the the set of paths passed will be added to those that already exist, otherwise the set will replace them. is_add - add or remove the set is_add=0, is_multipath=1 and an empty set, results in deleting the route. It is also considerably faster to add multiple paths at once, than one at a time: vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.11 100000 routes in .572240 secs, 174751.80 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.12 100000 routes in .528383 secs, 189256.54 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.13 100000 routes in .757131 secs, 132077.52 routes/sec vat# ip_add_del_route 1.1.1.1/32 count 100000 multipath via 10.10.10.14 100000 routes in .878317 secs, 113854.12 routes/sec vat# ip_route_add_del 1.1.1.1/32 count 100000 multipath via 10.10.10.11 via 10.10.10.12 via 10.10.10.13 via 10.10.10.14 100000 routes in .900212 secs, 111084.93 routes/sec Change-Id: I416b93f7684745099c1adb0b33edac58c9339c1a Signed-off-by: Neale Ranns <neale.ranns@cisco.com> Signed-off-by: Ole Troan <ot@cisco.com> Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

2017-10-05Distributed Virtual Router SupportNeale Ranns1-7/+1
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.
