2016-06-01VPP-83 Allow non-privileged clients to use the vpp binary API.Dave Barach1-1/+9
Use the command line argument "api-segment { uid <nnn> gid <nnn> }" to configure shared memory segment file ownership. Defaults to uid = gid = 0. Shared-memory segments are explicitly set to 0770 mode, aka "rwxrwx---". Change-Id: Ic5d596b68139add61e7de6ace035c57dfd030111 Signed-off-by: Dave Barach <dave@barachs.net>
2016-04-22Add a vpp_restart commandDave Barach1-4/+12
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.

2016-04-18Add support for AArch32Christophe Fontaine1-1/+1
gcc version 4.9.2 (Raspbian 4.9.2-10) Tested on Linux raspberrypi 4.4.6-v7+ #875 SMP Tue Apr 12 16:33:02 BST 2016 armv7l GNU/Linux CPUs may be little or big endian, detect with gcc flags, not the processor architecture Add a new flag $(PLATFORM)_uses_openssl which allows to disable the link with openssl lib. vlib/vlib/threads.c: startup.conf must: - specify the heapsize as we don't have hugepages on raspbian cpu { main-core 3 } heapsize 64M Corrects in various files the assumption uword == u64 and replaces 'u64' cast with 'pointer_to_uword' and 'uword_to_pointer' where appropriate. 256 CPUs may create an OOM when testing with small memory footprint ( heapsize 64M ), allows the number of VLIB_MAX_CPUS to be set in platforms/*.mk vppinfra/vppinfra/longjmp.S: ARM - copy r1 (1st parameter of the setjmp call) to r0 (return value) vppinfra/vppinfra/time.h: On ARMv7 in AArch32 mode, we can access to a 64bit register to retreive the cycles count. gcc on rpi only declare ARM_ARCH 6. Override this info, and check if it is possible to use 'mrrc'. /!\ the time function will NOT work without allowing the user mode access to the PMU.
