2016-04-22Add a vpp_restart commandDave Barach1-0/+234
vpp_restart solves the problem of restarting vpp and not exiting until the new vpp instance is sufficiently established to allow immediate binary API connections. The point is to avoid using arbitrary "sleep N" commands e.g. in CSIT shell scripts. We send SIGTERM to the current vpp process, and expect / depend on the process-monitor du jour to remove the vpp-api shared-memory segment. vpp_restart exits w/ status 0 if all is well, non-zero upon failure. In trying to make vpp_restart reliable, we discovered a recently-introduced heap corruption bug in .../dpdk/init.c, which caused vpp to crash on startup once every 20 times on a particular rig. If possible, we should check /var/log/syslog for evidence of unexpected multiple restarts during regression-testing.
