2022-03-24ip: The check for 'same packet' must include the FIB indexNeale Ranns1-0/+1
Type: fix otherwise if two packets arrive with the same source address but from different VRFs, then they are treated as the same and they use the same LB and thus share the same fate. but the lookup, when done, results in two different LBs, and hence the fate can be different.

2021-02-15ip: Path MTUNeale Ranns1-0/+46
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.

Add vpp specific properties to ip addresses for use in the api. .vapi_af -- returns [ADDRESS_IP4, ADDRESS_IP6] .vapi_af_name -- returns the string ['ip4', 'ip6'] Update tests to demonstrate usage.

2019-11-26fib: Table ReplaceNeale Ranns1-8/+9
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.

2019-06-26api: refactor format_vl_api_prefix_t return keysPaul Vinciguerra1-3/+3
format_vl_api_prefix_t returns a dict with keys 'address' and 'address_length', but other format_vl_api_prefix functions return a dict with 'prefix', and 'len'. Refactor all format_vl_api_prefix_t to return consistent keys 'address' and 'len'.

2019-06-18fib: fib api updatesNeale Ranns1-12/+67
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>
2019-02-01VTL: Fix issue with ipaddress library use under python2.Paul Vinciguerra1-3/+7
If you pass in a non-unicode 4-byte ipv6 address to ip_address, ipaddress interprets this as an IPv4Address. Under python2, ip_address interprets 'a7::' as a packed ipv4: 97.55.58.58 You can test with: --- import ipaddress try: text_type = unicode except NameError: text_type = str addr = ipaddress.ip_address('a7::') print(addr) --- Change-Id: I06c561e0ab7315869cc89d0bb08c05e743a90982 Signed-off-by: Paul Vinciguerra <pvinci@vinciconsulting.com>

The API calls that use any of vl_api_address_t, vl_api_ip4_address, vl_api_ip6_address_t, vl_api_prefix_t, vl_api_ip4_prefix_t, vl_api_ip6_prefix_t now accepts either the old style dictionary, a text string (2001:db8::/32) or an ipaddress ojbect. Unless it is called with '_no_type_conversion':True, it will also return an appropriate ipaddress object. Change-Id: I84e4a1577bd57f6b5ae725f316a523988b6a955b Signed-off-by: Ole Troan <ot@cisco.com>
