2020-03-06vcl: refactor vls to minimize lock usageFlorin Coras1-1/+2
Type: refactor - per vls worker private pool of sessions - deep copy of vls worker data structures on fork - maintain a global, i.e., heap allocated, and lock protected pool of elements that track sessions that are shared between workers (due to forking). Credit for uncovering the issue goes to Intel team contributing code to VSAP (Ping, Yuwei, Shujun, Guoao).

2019-08-27session: move ctrl messages from bapi to mqFlorin Coras1-3/+6
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.

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).

2019-01-30vls: 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.

2019-01-05vcl/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.
