2018-10-03sock api: fix registrations and client readsFlorin Coras1-5/+27
- When clients connect, instead of returing registration indicies return handles. By convention socket registrations will have the MSB set to 1. This makes it easy to distinguish them from shm registrations. - Fix client reads to allow for messages larger than 4kB (needed for the creat reply wherein the message table is provided).

2018-10-02PAPI: Use UNIX domain sockets instead of shared memoryOle Troan1-29/+72
Adds support for running the API purely across Unix domain sockets. Usage: vpp = VPP(use_socket=True) Change-Id: Iafc1301e03dd3edc3f4d702dd6c0b98d3b50b69e Signed-off-by: Ole Troan <ot@cisco.com>
2018-09-19socket api: do not delay sending of messagesFlorin Coras1-58/+35
Instead of relying on main epoll loop to send messages, try to send as soon as possible. Change-Id: I27c0b4076f3599ad6e968df4746881a6717d4299 Signed-off-by: Florin Coras <fcoras@cisco.com>
2018-08-10vcl: support for eventfd mq signalingFlorin Coras1-2/+2
- 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.

2018-05-10Remove the historical memfd api segment bootstrapDave Barach1-66/+25
Clean up default and vpp_api_test custom private api segment allocator ring configurations. Change-Id: I145b6d64ba0a6315b5ccb07909c8256eeb772146 Signed-off-by: Dave Barach <dave@barachs.net>
2018-01-25session: add support for memfd segmentsFlorin Coras1-20/+22
- 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>
2018-01-15svm: refactor memfd and remove ssvm_ethFlorin Coras1-9/+9

2018-01-09api: refactor vlibmemoryFlorin Coras1-0/+804
- 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>
