2019-11-15tests: Add UT to test incomplete MPLS adjacencies send ARP requestsNeale Ranns1-3/+42

2019-11-11ip: functional interface to ip fragmentationOle Troan1-2/+37
This provides a functional interface to IP fragmentation. Allowing external features to fragment. Supports arbitrary encap size, for e.g. MPLS or inner fragmentation of tunnels. This also removed dual loop in MAP that was fundamentally broken.

Type: fix Since CentOS 8, RPM build script doesn't accept '#!/usr/bin/env python' as a valid shebang line. It requires scripts to explicitly chose between python2 or python3.

2019-06-18fib: fib api updatesNeale Ranns1-66/+78
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>

2017-04-24Improve Load-Balance MAPsNeale Ranns1-0/+359
- only build them for popular path-lists (where popular means more than 64 children) the reason to have a map is to improve convergence speed for recursive prefixes - if there are only a few this technique is not needed - only build them when there is at least one path that has recursive constraints, i.e. a path that can 'fail' in a PIC scenario. - Use the MAPS in the switch path. - PIC test cases for functionality (not convergence performance) Change-Id: I70705444c8469d22b07ae34be82cfb6a01358e10 Signed-off-by: Neale Ranns <nranns@cisco.com>
2017-04-07MPLS McastNeale Ranns1-22/+255
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.

2016-12-23make test: improve handling of packet capturesKlement Sekera1-17/+24
Perform accounting of expected packets based on created packet infos. Use this accounting info to automatically expect (and verify) the correct number of packets to be captured. Automatically retry the read of the capture file if scapy raises an exception while doing so to handle rare cases when capture file is read while only partially written during busy wait. Don't fail assert_nothing_captured if only junk packets arrived. Change-Id: I16ec2e9410ef510d313ec16b7e13c57d0b2a63f5 Signed-off-by: Klement Sekera <ksekera@cisco.com>
2016-12-16make test: improve robustness and performanceKlement Sekera1-23/+6
Introduce an API which asserts empty capture for interface. Throw exception in old API if the capture does not exist, thus making it clear if the test expects packets to arrive or not. Improve performance by not doing sleeps after starting the packet generator, rather lazily deleting captures when needed. Fix wrong usage of packet.show() in various tests.
