2019-02-27session: refactor local/cut-through listensFlorin Coras1-61/+52
Introduce a cut-through transport as replacement to local sessions. This first patch removes the per app local listener pools and switches local listeners to sessions with cut-through transport. Change-Id: I98b20c25bc5df5f4110bf66f76c650a973032618 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-01-05vcl/session: add api for changing session app workerFlorin Coras1-0/+50
In case of multi process apps, after forking, the parent may decide to close part or all of the sessions it shares with the child. Because the sessions have fifos allocated in the parent's segment manager, they must be moved to the child's segment manager.

2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-4/+35
- 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 Coras1-5/+10
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.

- adds session layer support for datagram based protocols - updates udp to work in pure connectionless and datagram mode.
