2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-46/+120
- 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.

2018-07-27vcl: use events for epoll/select/read/writeFlorin Coras1-2/+6
Have vcl poll and wait on the event message queues as opposed to constantly polling the session fifos. This also adds event signaling to cut through sessions. On the downside, because we can't wait on multiple condvars, i.e., when we have multiple message queues because of cut-through registrations, we do timed waits.

2018-03-02session: first approximation implementation of tlsFlorin Coras1-0/+60
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 Coras1-112/+145
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>

2018-01-11api: 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>
