2018-10-04udp_echo: fix cut-through server modeFlorin Coras1-206/+217

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-7/+2
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>

2018-05-09session: cleanup session tx functionFlorin Coras1-20/+49
- rework the function to declutter and avoid building more than one tx frame - add dual loop although benefits in my tests seem to be minimal - improve tcp/udp echo external apps. They have slightly better throughput than internal echo apps. - udp bugfixes Change-Id: Iea4a245b1b1bb407a7f403dedcce2664a49f774b Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-04-18udp/session: refactor to support dgram modeFlorin Coras1-172/+303
- adds session layer support for datagram based protocols - updates udp to work in pure connectionless and datagram mode. The existing connected mode is now 'accessible' for apps as a dummy UDPC, as in, connected udp, protocol. - updates udp_echo, echo client, echo server code to work in datagram mode.

2018-02-14session: support local sessions and deprecate redirectsFlorin Coras1-44/+86
Memfd backed shared memory segments can only be negotiated over sockets. For such scenarios, the existing redirect mechanism that establishes cut-through sessions does not work anymore as the two peer application do not share such a socket. This patch adds support for local sessions, as opposed to sessions backed by a transport connection, in a way that is almost transparent to the two applications by reusing the existing binary api messages. Moreover, all segment allocations are now entirely done through the segment manager valloc, so segment overlaps due to independent allocations previously required for redirects are completely avoided. The one notable characteristic of local sessions (cut-through from app perspective) notification messages is that they carry pointers to two event queues, one for each app peer, instead of one. For transport-backed sessions one of the queues can be inferred but for local session they cannot. Change-Id: Ia443fb63e2d9d8e43490275062a708f039038175 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-02-05session: segment manager refactorFlorin Coras1-1/+1
- use valloc as a 'central' segment baseva manager - use per segment manager segment pools and use rwlocks to guard them - add session test that exercises segment creation - embed segment manager properties into application since they're shared - fix rw locks Change-Id: I761164c147275d9e8a926f1eda395e090d231f9a Signed-off-by: Florin Coras <fcoras@cisco.com>

2018-01-25session: add support for memfd segmentsFlorin Coras1-12/+11
- update segment manager and session api to work with both flavors of ssvm segments - added generic ssvm slave/master init and del functions - cleanup/refactor tcp_echo - fixed uses of svm fifo pool as vector Change-Id: Ieee8b163faa407da6e77e657a2322de213a9d2a0 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-01-22svm: queue sub: Add conditional timed waitMohsin Kazmi1-1/+1
On reviece side svm queue only permits blocking and non-blocking calls. This patch adds timed wait blocking functionality which returns either on signal/event or on given time out. It also preserves the original behavior, so it will not hurt client applications which are using svm queue.

2018-01-09api: refactor vlibmemoryFlorin Coras1-19/+13
- separate client/server code for both memory and socket apis - separate memory api code from generic vlib api code - move unix_shared_memory_fifo to svm and rename to svm_fifo_t - overall declutter Change-Id: I90cdd98ff74d0787d58825b914b0f1eafcfa4dc2 Signed-off-by: Florin Coras <fcoras@cisco.com>
