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.

2017-10-05Clean 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>
2017-10-03api: fix internal client registrationsFlorin Coras1-0/+2
Makes sure vlib_rp and shmem_hdr are initialized for internal registrations. They are needed for keepalive msg exchanges. Change-Id: I805dec2d2aa84b1efdc1fdd692fc1d94389b776e Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-10-03Repair vlib API socket serverDave Barach8-271/+1824
- 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>

2017-08-18API: More gracefully fail when opening shared memory segment fails.Ole Troan1-2/+6
API clients would fail with an ASSERT (and core dump) whenever the API shared memory segment could not be opened. This returns an error value to the client's connect instead. Change-Id: Id122a3a090b24b139c382ae09f341bde61fd2540 Signed-off-by: Ole Troan <ot@cisco.com>
2017-08-14jvpp: make shm_prefix configurable (VPP-591)Jan Srnicek1-3/+16
svm.c - set default map region root path only if root path is not already present memory_shared.c - added option for tests to send memory region name and root path in one variable, if so name and root path are separated here and set to map region structure so find function can find it properly jvpp-registry.c - added parameters shmPrefix to be able pass + removed sudo restriction specific shared memory prefix that is used while starting python tests(see framework.py) JVppRegistyImpl - added option to specify shmPrefix VppJNIConnection - added option to specify shmPrefix Change-Id: I3f89f867fb9b20eef00fbd497cb0e41b25d6eab7 Signed-off-by: Jan Srnicek <jsrnicek@cisco.com> Signed-off-by: Matej Perina <mperina@cisco.com>

2017-01-05Fix uninitialized stack local, VPP-581Dave Barach1-0/+3
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.
