2018-03-16Fix a long-latent bi=0 bug in vlib_buffer_add_dataDave Barach2-2/+2
Change vlib_buffer_add_data() so it interprets ~0 to mean please allocate a new buffer, instead of 0. Fixed a couple of calls to pass ~0 instead of 0. Zero has always been a valid buffer index, we never happened to actually use it until recent buffer allocator changes. The presenting symptom: ASSERT failure when running "make TEST=test_mpls test-debug" Change-Id: Ic909913c1d464b3434d6d47e0c58f978806854d5 Signed-off-by: Dave Barach <dave@barachs.net>

2018-01-31vlib: allocating buffers on thread-x and freeing them on thread-y causesSteven2-11/+10
a crash on debug image (VPP-1151) In debug image, there is extra code to validate the buffer when it is freed. It uses the hash table to lookup the buffer index with spinlock to prevent contention. However, there is one spinlock for each worker thread. So allocating the buffer on thread-x and freeing the same buffer on thread-y causes the validation to fail on thread-y. The fix is to have only one spinlock, stored in vlib_global_main.

2018-01-30VPP-899: Run VPP under SELinuxBilly McFall1-4/+20
Add an SELinux profile such that VPP can run under SELinux on RPM based platforms. The SELinux Policy is currently only implemented for RPM packages, specifically, Fedora, CentOS and RHEL. Doxygen User Documentation has been included (selinux_doc.md). Once some discussion on file locations has completed (see vpp-devlist), updates to the Debug CLI documentation will also need to be updated. Additional changes: Patch Set 2: - Rework selinux_doc.md such that each line is only 80 characters instead of each sentence on a line. Made additonal minor chnages to the text. - Update vHost Debug CLI documentation to reflex new socket location. Cleaned up some text from when I originally wrote it, to better reflex proper use. - Update exec Debug CLI documentation to be more inline with suggested helptext, added text regarding recommended script file location. - For Debian builds, create the /var/log/vpp/ directory. I don't use Debian very much, so please pay extra attention to build-data/platforms.mk and build-root/deb/debian/.gitignore. - Per discussion on VPP call, changed the default log location to /var/log/vpp/vpp.log. - Changed the socket location for vHost in AutoConfig to /var/run/vpp/. Patch Set 3: - Update selinux_doc.md based on comments. Change-Id: I400520dc33f1ca51012d09ef8fe5a7b7b96c631e Signed-off-by: Billy McFall <bmcfall@redhat.com>

2017-12-15VPP-1102: fix dangling references in RPC handlingDave Barach3-0/+19
Queue RPC calls and send them from the main dispatch loop. As things stood, if the vpp main input queue filled, worker threads could enter a barrier-sync spin-wait in the middle of processing a frame. If thread 0 decided to recreate worker thread data structures, the worker thread(s) could easily crash. Legislate the problem out of existence by enqueueing RPC messages only from the main dispatch loop. At that point, doing a barrier-sync wait is perfectly OK.
