2020-08-25api: register endian handlers for reply messagesOle Troan1-1/+20
Endian handlers was not registered for reply messages. Causing endian-neutral handlers to crash. Type: fix Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: Id14173300ee1ab2601e92d58c70d2fa260814b69
2020-05-27api: make vpp api handlers endian independentOle Troan1-0/+20
Add a new boolean to signal that the API infrastructure should performan any required endian conversions for the API handler. am->is_autoendian[mm->msg_id_base + VL_API_MAP_ADD_DOMAIN] = 1; Similarly add new REPLY_ macros that perform endian conversion. These changes do not change the on-the-wire encoding of the API messages, and therefore the API CRC is not changed.

2020-05-25api: add new stream message conventionOle Troan1-0/+37
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>
2020-02-26api: add macro that zeros out api reply bufferPaul Vinciguerra1-0/+32
Add macros REPLY_MACRO2_ZERO, REPLY_MACRO3_ZERO that zeros the buffer before the values are set. This way if say, a u8[64] field is only filled with 10 octets, the previous buffers trailing contents are not sent.

2019-12-17ip: Protocol Independent IP NeighborsNeale Ranns1-13/+4
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.

2019-09-25api: split api generated filesOle Troan1-0/+15
Split generation of API message enum and the typedefs into separate files, so that the type file can be included from elsewhere. Generate a C file for VPP that contains the API registration, this was previously done via X macros by the C pre- processor. This allows deleting lots of skeleton/copy paste code for each feature. plugins/flowprobe plugins/map examples/sample-plugin vnet/ipip used as Guinea pigs. Generate a C Test file for VAT, that does the same for VAT plugins. Also add support for a per-message CLI option, that is currently limited to VAT help text. option vat_help = "<help text>"; Type: refactor Change-Id: I245e3104bb76f7e1fb69a59ab20cc7c8dfcdd460 Signed-off-by: Ole Troan <ot@cisco.com>

2018-06-14Fix SEGV in generic event sub reaperMatthew Smith1-1/+1
When a client subscribed to receive events disconnects from the API, while deleting their subscription, a hash lookup was being performed against a pointer that did not refer to a hash, resulting in a SEGV. Perform the hash lookup against the correct hash. Change-Id: I011d7479e2c3b9ee50721cf7499385c3ff7f704a Signed-off-by: Matthew Smith <mgsmith@netgate.com>
