2020-08-18vcl: allow vcl worker index to be set by applicationsIJsbrand Wijnands1-0/+5
When using vppcom_session* apis to setup TCP sessions in applications build outside of the VPP repository, it is necessary to set the worker_index explicitly when these apis are called from the none-VCL worker threads. An example is when data is to be sent to the TCP session that is originated from a different thread, like the main program thread or from the bin api thread. This change allows the application to set it. Type: fix Signed-off-by: IJsbrand Wijnands <ice@cisco.com> Change-Id: I37f3654a49ea9a8cf3a0d3d0e672583018c12299 (cherry picked from commit 6017ff0dd7a27c062d0ad4687bfc70a69747ac55)

2019-07-19session: Use parent_handle instead of transport_optsNathan Skrzypczak1-1/+1
Type: feature This is mostly used for quic in the case of a stream creation (i.e. connect on an already established QUIC session). 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>
2019-07-18vcl: add QUIC supportNathan Skrzypczak1-1/+18
Type: feature * Adds the concept of a "connectable listener" : a session that can be both connected and accepted on. * vppcom_session_is_connectable_listener (fd) that tells if the fd is a connectable listener * vppcom_session_listener (fd) that gives you the listener's fd that accepted the session (if any) * vppcom_session_n_accepted (fd) that gives the number of sessions a listener accepted.

2019-01-26vcl: add api to expose worker message queues epfdFlorin Coras1-0/+8
This only works if vcl is configured to do eventd based message queue notifications, instead of condvars. For that, add "use-mq-eventfd" to vcl startup conf. Change-Id: Id0f0288a40ec7d3daef7370f8b88420425867ab6 Signed-off-by: Florin Coras <fcoras@cisco.com>

2019-01-07vcl/ldp: add locked sessions shim layerFlorin Coras1-2/+4
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 Coras1-1/+4
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 Coras1-11/+13
- 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 Coras1-0/+1
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.
