2018-01-09api: refactor vlibmemoryFlorin Coras1-2803/+0
- 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 Coras1-2/+2

2017-12-15VPP-1102: fix dangling references in RPC handlingDave Barach1-27/+39
Queue RPC calls and send them from the main dispatch loop. As things stood, if the vpp main input queue filled, worker threads could enter a barrier-sync spin-wait in the middle of processing a frame. If thread 0 decided to recreate worker thread data structures, the worker thread(s) could easily crash. Legislate the problem out of existence by enqueueing RPC messages only from the main dispatch loop. At that point, doing a barrier-sync wait is perfectly OK.

2017-10-18CSIT-844: fix binary api rx pthread heap push/popDave Barach1-3/+5
We need to push/pop the rx pthread's heap without affecting other thread(s). Search clib_per_cpu_mheaps, locate an unused slot. Duplicate the main thread heap pointer in that slot, and set __os_thread_index appropriately. Miscellaneous cleanups. Print exec_inband results as a vector, instead of as a format string. Don't bail out of vpp_api_test with results pending, e.g. at the end of a vpp_api_test script. Even though vpp will eventuallly garbage-collect them, We don't want to leave allocated reply messages lurking in the api message allocation rings...

2017-10-05Clean up "show api ring" debug CLIDave Barach1-3/+11
Add a primary svm_region_t pointer to the api_main_t so we can always find the primary region, even when processing an API message from a memfd segment. Change-Id: I07fffe2ac1088ce44de10a34bc771ddc93af967d Signed-off-by: Dave Barach <dave@barachs.net>

2017-10-03Repair vlib API socket serverDave Barach1-188/+529
- 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>

2017-09-25Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/DownJohn Lo1-3/+27
For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@cisco.com>

Sporadically messes up the client message allocation ring, by setting c->message_bounce[msg_id] non-zero. A day-1 bug, made blatantly obvious by the python API language binding for no particular reason. Manually cherry-picked from stable/1701 due to the recent tree reorganization.
