2018-10-02tls: fix disconnects for sessions with pending dataFlorin Coras3-4/+13
TLS can enqueue events to itself when app session queue cannot be entirely drained. If a pending disconnect is handled before any such event, session layer may try to dequeue data on deallocated sessions.

2018-08-10vcl: support for eventfd mq signalingFlorin Coras9-69/+249
- 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 Coras9-32/+46
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.

2018-06-26tcp/session: tx optimizationsFlorin Coras1-1/+0
- cache and reuse tcp options and rcv_wnd for session layer tx bursts - avoid reading/setting total_length_not_including_first_buffer. It's part of a buffer's second cache line so it comes at a "cost". Change-Id: Id18219c2f7e07cf4c63ee74f9cdd9e5918904036 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-06-22session: improve session lookup speedsFlorin Coras1-57/+24
It would seem that this avoids using the stack for computing the subsequent crc32 by storing the 2 x u64 ip4 5-tuple key into two registers. Probably the cast to the "convenience" data structure "masks" the fact that the key is 16B. Probably ... :-) "sh run" on an ip4 tcp sender reports that the number of clocks spent in tcp_input, where a session lookup is performed, drops ~25% (from ~100 clocks/packet to ~75 clocks/packet) Change-Id: I50d647115ac72f8407bff7e3b73328ba42f0ddb5 Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-06-11udp: fix for multiple workers and add testFlorin Coras3-1/+9

2018-06-01session: improve disconnect handlingFlorin Coras3-11/+37
If the caller is the session owning thread or the main thread with a worker barrier sync (cli/api) add an event to the pending disconnects vector in the session node and entirely avoid using the event queue. Useful for bursts of disconnects (like an app detach). If disconnects come from a processes, be willing to retry enqueueing the disconnect to the event queue multiple times.
