2019-02-14Add -fno-common compile optionBenoît Ganne1-1/+1
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

2019-02-04session: cleanup part 1Florin Coras1-2/+2
Rename core data structures. This will break compatibility for out of tree builtin apps. - stream_session_t to session_t - server_rx/tx_fifo to rx/tx_fifo - stream_session.h to session_types.h - update copyright Change-Id: I414097c6e28bcbea866fbf13b8773c7db3f49325 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-01-30vls: support passive listenersFlorin Coras1-10/+17
If an application worker calls listen on a session, vpp registers the worker to the listener's work load balance group and, as new connections are accepted, it may potentially push accept notifications to it. There are however applications, like nginx, that on some workers may never accept new connections on a session they've started listening on. To avoid accumulating accept events on such workers, this patch adds support for passive listeners. That is, workers that have started listening on a session but then never call accept or epoll/select on that listener.

2019-01-29vls: multi-process and multi-threaded apps improvementsFlorin Coras1-0/+3
- More fine tuning for multi-process applications. - Experimental support for multi-thread apps. This is meant for app whose threads are not vcl workers and the sessions are shared between them. Change-Id: Ie07651da5f2cdcf39f5dead5431f50ad39cf3f74 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-01-07vcl/ldp: add locked sessions shim layerFlorin Coras1-0/+3
Moves LDP logic that allows sharing of sessions between multi-process app workers into a separate VCL shim layer. Also refactors LDP to use the new layer. Change-Id: I8198b51eae7d099a8c486e36b29e3a0cb8cee8e9 Signed-off-by: Florin Coras <fcoras@cisco.com>
2019-01-05vcl/session: add api for changing session app workerFlorin Coras1-5/+19
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 Coras1-1/+62
- 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 Coras1-1/+61
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.
