From 59b2565cd91a67ced650739f36129650830211ac Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Sun, 10 Sep 2017 15:04:27 -0400 Subject: Repair vlib API socket server - 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 (, 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 Signed-off-by: Dave Wallace Signed-off-by: Florin Coras --- src/vlibapi/api_helper_macros.h | 141 ++++++++++++++++++++-------------------- 1 file changed, 71 insertions(+), 70 deletions(-) (limited to 'src/vlibapi/api_helper_macros.h') diff --git a/src/vlibapi/api_helper_macros.h b/src/vlibapi/api_helper_macros.h index 052cc6e78b5..fc9374f8a26 100644 --- a/src/vlibapi/api_helper_macros.h +++ b/src/vlibapi/api_helper_macros.h @@ -27,82 +27,83 @@ #define REPLY_MSG_ID_BASE 0 #endif -#define REPLY_MACRO(t) \ -do { \ - unix_shared_memory_queue_t * q;
