2018-01-09api: refactor vlibmemoryFlorin Coras1-4/+4
- 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>
2017-10-03Repair vlib API socket serverDave Barach1-1/+1
- 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>
2017-09-11memif: mode ip is not settable from binary APISteven1-0/+3
While mode ip is supported via the CLI for creating a memif interface, it is not settable from the binary API due to missing code. While at it, update the help usage to include the missing keyword secret. Change-Id: Ia9c71f4017210a5e1733ce4992fbb566b7d20c1a Signed-off-by: Steven <sluong@cisco.com>
2017-09-08memif: fix coverity warnings as of 9/7Steven1-2/+5
1. coverity complains about "buffer not null terminated" for strncpy because we pass the size of the destination to the call which is equal to the true size of the destination. We subtract 1 for the size to accommodate the null like all other places are already doing it. 2. Add a check to tx_queues in memif_interface_tx_inline to avoid "divide by zero". 3. To avoid null pointer dereference in memif_create_if, change the goto done rather than goto error and spit a more meaningful error rather than silent about it. 4. Shuffle a line to avoid "check after use" in vl_api_memif_delete_t_handler. Change-Id: Icba7ecd5362c012a48ac35795d31aab356617420 Signed-off-by: Steven <sluong@cisco.com>

2017-06-25memif: If rx/tx_queues are unset, use default valuesMilan Lenco1-2/+12
The standard behaviour for binary API is that zeroed arguments are treated as if the default values were set. This way the configurator does not need to know what default values are. This, however, wasn't the case for rx_queues and tx_queues in memif_create binary API message.

2017-05-31memif: multi-queues supportSteven1-0/+5
- Add rx-queues and tx-queues option to the create memif CLI - Add vlib_worker_thread_barrier_sync () to memif_conn_fd_read_ready () as the latter function may disconnect the ring and clean up the shared memory. - On transmit, write the rid (queue number) to the socket. - On receive, read the rid and trigger the interrupt for the corresponding thread.
