2018-01-09api: refactor vlibmemoryFlorin Coras1-26/+3
- 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>
2018-01-05sock api: add infra for bootstrapping shm clientsFlorin Coras1-70/+254
- add function to sock client that bootstraps shm api - allow sock clients to request custom shm ring configs Change-Id: Iabc1dd4f0dc8bbf8ba24de37f4966339fcf86107 Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-10-06Coverity fixes for API socketChris Luke1-3/+3
- Coverity whines about a zero-length field not being initialized. Change the struct setup to an initializer which will implicitly zero all unused fields, and add the coverity notation that should stop it whining. One or both of these should shut it up! - Fix some incorrect use of ntohl that was tainting values; in these cases htonl should have been used, and avoid a double-swap.

2017-10-03Repair vlib API socket serverDave Barach1-0/+240
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>
