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.

2017-11-13Instead of a min term size, use a default (VPP-1061)Chris Luke1-16/+21
- In the bug report, Docker was sometimes giving shells a 0,0 terminal size. The minimum-term-size logic meant that VPP assumed the terminal had 1 row. The pager functioned, but of course overwrote the one line with its own prompt. - Instead of a minimum size, always use a default size when the either terminal dimension is 0.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.
