2019-10-09session: Add certificate storeNathan Skrzypczak1-0/+40
Type: feature This changes the behavior of both API calls APPLICATION_TLS_CERT_ADD & APPLICATION_TLS_KEY_ADD certificates and keys aren't bound to an app, they are passed to it via connect / listen using the message queue. This should be followed by a per protocol (QUIC/TLS) crypto_context store to save devrived structs Change-Id: I36873bc8b63b5c72776c69e8cd9febc9cae31882 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>
2019-09-03api: enforce vla is last and fixed string typeOle Troan1-1/+1
Enforce that variable length fields are the last element of API messages. Add a 'fixed' version of string type, since dealing with multiple variable length strings turned out too painful for the C language bindings. The string type is now: { string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64] string name[]; // Variable length string with embedded len field (vl_api_string_t) }; The latter notation could be made available to other types as well. e.g. { vl_api_address_t addresses[]; } instead of { u32 n_addr; vl_api_address_t addresses[n_addr]; }; Type: fix Change-Id: I18fa17ef47227633752ab50453e8d20a652a9f9b Signed-off-by: Ole Troan <ot@cisco.com>
2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-18/+76
Type:refactor Moves connect, disconnect, bind, unbind and app detach to message queue from binary api. Simplifies app/vcl interaction with the session layer since all session control messages are now handled over the mq. Add/del segment messages require internal C api changes which affect all builtin applications. They'll be moved in a different patch and might not be back portable to 19.08.

We want do default parent_handle to INVALID to be able to distinguish it from parent_handle = 0 Change-Id: Id5ac0b0155a3c44e51334231b711e4fd87a96a10 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-2/+32
- support eventfd based mq signaling. Based on configuration, vcl epoll/select can use either condvars or epoll on mq eventfds. - add vcl support for memfd segments - vpp explicitly registers cut-through segments with apps/vcl - if using eventfd, make ldp allow one call to libc_epoll_create. Needed for the message queue epfd - update svm_queue_t to allow blocking calls with eventfd signaling.

- 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.

2018-03-02session: first approximation implementation of tlsFlorin Coras1-0/+28
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 Coras1-4/+19
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>
2018-01-23VPPAPIGEN: 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>

2017-10-28session: rules tablesFlorin Coras1-0/+38
This introduces 5-tuple lookup tables that may be used to implement custom session layer actions at connection establishment time (session layer perspective). The rules table build mask-match-action lookup trees that for a given 5-tuple key return the action for the first longest match. If rules overlap, ordering is established by tuple longest match with the following descending priority: remote ip, local ip, remote port, local port. At this time, the only match action supported is to forward packets to the application identified by the action.

2017-10-10session: add support for application namespacingFlorin Coras1-12/+39
Applications are now provided the option to select the namespace they are to be attached to and the scope of their attachement. Application namespaces are meant to: 1) constrain the scope of communication through the network by association with source interfaces and/or fib tables that provide the source ips to be used and limit the scope of routing 2) provide a namespace local scope to session layer communication, as opposed to the global scope provided by 1). That is, sessions can be established without assistance from transport and network layers. Albeit, zero/local-host ip addresses must still be provided in session establishment messages due to existing application idiosyncrasies. This mode of communication uses shared-memory fifos (cut-through sessions) exclusively. If applications request no namespace, they are assigned to the default one, which at its turn uses the default fib. Applications can request access to both local and global scopes for a namespace. If no scope is specified, session layer defaults to the global one. When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY) binds are converted to binds to the requested interface.
