A NAT sub-plugin doing statically configured match/rewrite on IP4 input or output. It's stateless (no connection tracking). Currently it supports rewriting of SA, DA and TCP/UDP ports. It should be simple to add new rewrites if required. API: pnat_binding_add, pnat_binding_del, pnat_bindings_get, pnat_interfaces_get CLI: set pnat translation interface <name> match <5-tuple> rewrite <5-tuple> {in|out} [del] show pnat translations show pnat interfaces Trying a new C based unit testing scheme. Where the graph node is tested in isolation. See pnat/pnat_test.c. Also added new cmake targets to generate coverage directly.

2020-10-13stats: counters data modelOle Troan3-12/+162
This adds a new data model for counters. Specifying the errors severity and unit. A later patch will update vpp_get_stats to take advantage of this. Only the map plugin is updates as an example. New .api language: A new "counters" keyword to define counter sets. counters map { none { severity info; type counter64; units "packets"; description "valid MAP packets"; }; bad_protocol { severity error; type counter64; units "packets"; description "bad protocol"; }; }; Each counter has 4 keywords. severity, which is one of error, info or warn. A type, which is one of counter64 or gauge64. units, which is a text field using units from YANG. paths { "/err/ip4-map" "map"; "/err/ip6-map" "map"; "/err/ip4-t-map" "map"; "/err/ip6-t-map" "map"; }; A new paths keyword that maps the counter-set to a path in the stats segment KV store.

2020-05-25api: add new stream message conventionOle Troan2-1/+8
Instead of having to wrap dump/detail calls in control ping, send details messages in between a normal reply / request pair. As expressed in the below service statement. Example: service { rpc map_domains_gets returns map_domains_get_reply stream map_domain_details; }; define map_domains_get { u32 client_index; u32 context; u32 cursor; }; define map_domains_get_reply { u32 context; i32 retval; u32 cursor; }; To avoid blocking the main thread for too long, the replies are now sent in client message queue size chunks. The reply message returns VNET_API_ERROR_EAGAIN when there is more to read. The API handler must also include a "cursor" that is used to the next call to the get function. API handler example: REPLY_AND_DETAILS_MACRO (VL_API_MAP_DOMAINS_GET_REPLY, mm->domains, ({ send_domain_details (cursor, rp, mp->context); })); The macro starts from cursor and iterates through the pool until vl_api_process_may_suspend() returns true or the iteration reaches the end of the list. Client Example: cursor = 0 d = [] while True: rv, details = map_domains_get(cursor=cursor) d += details if rv.retval == 0 or rv.retval != -165: break cursor = rv.cursor or the convenience iterator: for x in vpp.details_iter(vpp.api.map_domains_get): pass or list(details_iter(map_domains_get)) Change-Id: Iad9f6b41b0ef886adb584c97708dd91cf552749e Type: feature Signed-off-by: Ole Troan <ot@cisco.com>

crcchecker is a tool for enforcement of the binary API. 1. Production APIs should never change. 2. An API can be deprecated across three release cycles. Release 1: API is marked as deprecated. option deprecated="vyy.mm"; option replaced_by="new_api_2"; Release 2: both old and new APIs are supported Release 3: the deprecated API is deleted. 3. APIs that are experimental / not released are not checked. An API message can be individually marked as in progress, by: option status="in_progress"; In the API definition. The definition of a "production API" is if the major version in the API file is > 0. extras/scripts/crcchecker.py --check-patchset # returns -1 if backwards incompatible extras/scripts/crcchecker.py --dump-manifest extras/scripts/crcchecker.py --git-revision v20.01 <files> extras/scripts/crcchecker.py -- diff <oldfile> <newfile> This patch integrates the tool in "make checkstyle-api".
