2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-1341/+37
Type: feature - ip-neighbour: generic neighbour handling; APIs, DBs, event handling, aging - arp: ARP protocol implementation - ip6-nd; IPv6 neighbor discovery implementation; separate ND, MLD, RA - ip6-link; manage link-local addresses - l2-arp-term; events separated from IP neighbours, since they are not the same. vnet retains just enough education to perform ND/ARP packet construction. arp and ip6-nd to be moved to plugins soon.

2019-12-04ip: populate ip_reassembly_get_reply correctlyMatthew Smith1-3/+4
Type: fix Fixes: de34c35fc The API handler for requests to retrieve IP reassembly settings was modified to support shallow virtual reassembly. It retrieves settings into local variables now instead of directly into the reply message. The fields in the reply message were not being populated using those variables. So the reply message was being sent with all 0's, except in the is_ip6 field. Also, the max_reassembly length field in the reply message was not being populated.

2019-11-26fib: Table ReplaceNeale Ranns1-117/+73
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.

2019-09-16api: autogenerate api trace print/endianOle Troan1-0/+1
In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files. In two formats, "custom-dump" and "dump". "dump" gives a human friendly list, and "custom-dump" is meant to give a list of commands that can be fed to VAT. This patch only deals with "dump". Prior to this fix, auto-generation was only done for the basic types. This fix adds support for any type, including lists, and supports pretty-printing of enums, strings, IP addresses, MAC addresses and so on.

2019-06-18fib: fib api updatesNeale Ranns1-803/+253
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>

Some API action handlers called vl_msg_ai_send_shmem() directly. That breaks Unix domain socket API transport.

Scan IPv4 and IPv6 neigbor pool entries once a minute to keep them up to date. The neighbor of an entry is probed if its time-stamp is older than 1 minute. If the neighbor respond, its time-stamp will be updated. If there is no response from a neighbor, its entry will be deleted when the time-stamp of the entry become more than 4 minutes old. Static neighbor entries are not probed nor deleted. Implemented CLI and API to enable and disable priodic scan of IPv4, IPv6 or both types of IP neighbors. CLI is "ip scan-neighbor" and API is "ip_scan_neighbor_enable_disable". Other IP neighbor scan parameters can also be changed from their defaults via the CLI/API.
