2018-03-07tls: enforce certificate verificationFlorin Coras7-82/+122
- add option to use test certificate in the ca chain - add hostname to extended session endpoint fields and connect api parameters. If hostname is present, certificate validation is enforced. - use /etc/ssl/certs/ca-certificates.crt to bootstrap CA cert. A different path can be provided via startup config Change-Id: I046f9c6ff3ae6a9c2d71220cb62eca8f7b10e5fb Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-03-02session: first approximation implementation of tlsFlorin Coras15-152/+525
It consists of two main parts. First, add an application transport type whereby applications can offer transport to other applications. For instance, a tls app can offer transport services to other applications. And second, a tls transport app that leverages the mbedtls library for tls protocol implementation.

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras15-429/+1161
Memfd backed shared memory segments can only be negotiated over sockets. For such scenarios, the existing redirect mechanism that establishes cut-through sessions does not work anymore as the two peer application do not share such a socket. This patch adds support for local sessions, as opposed to sessions backed by a transport connection, in a way that is almost transparent to the two applications by reusing the existing binary api messages. Moreover, all segment allocations are now entirely done through the segment manager valloc, so segment overlaps due to independent allocations previously required for redirects are completely avoided. The one notable characteristic of local sessions (cut-through from app perspective) notification messages is that they carry pointers to two event queues, one for each app peer, instead of one. For transport-backed sessions one of the queues can be inferred but for local session they cannot. Change-Id: Ia443fb63e2d9d8e43490275062a708f039038175 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-02-05session: segment manager refactorFlorin Coras9-446/+596

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>
2018-01-11api: remove transport specific code from handlersFlorin Coras1-11/+11
This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that. Furthermore, code that checks queue size, for tail dropping, is not updated. Done for the following apis: Plugins - acl - gtpu - memif - nat - pppoe VNET - bfd - bier - tapv2 - vhost user - dhcp - flow - geneve - ip - punt - ipsec/ipsec-gre - l2 - l2tp - lisp-cp/one-cp - lisp-gpe - map - mpls - policer - session - span - udp - tap - vxlan/vxlan-gpe - interface VPP - api/api.c OAM - oam_api.c Stats - stats.c Change-Id: I0e33ecefb2bdab0295698c0add948068a5a83345 Signed-off-by: Florin Coras <fcoras@cisco.com>

2017-12-10make sure the very first fragment triggers an rx_callbackAndreas Schultz1-0/+1
On the first session server, the first payload packet gets queued but the Rx callback will only be invoked when the second packet is received. By initializing enqueue_epoch in the session, we can make sure that the RX callback will be invoked for the first packet as well.
