2018-01-29vlib: 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. Change-Id: Ic383846cefe84a3e262255afcf82276742f0f62e Signed-off-by: Steven <sluong@cisco.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.

- 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.

2017-09-21vppctl,cli: Improve non-interactive vppctl (VPP-944)Chris Luke1-51/+308
Short version: Make vppctl behave as expected when run from scripts, or without a controlling terminal, and especially when using it with VPP commands on its command line ("non-interactively"). In particular, prevent the welcome banner and VPP CLI prompt from being sent by VPP when being used in these ways. vppctl ------ - Improve vppctl's detection of non-interactive sessions. - Pass non-interactiveness in the terminal type telnet option as a value distinct from "dumb" (which means non-ANSI capable.) - Make tty setup handling more robust. - Only send non-interactive command once we've sent the terminal type, to ensure correct event sequence; we need the VPP cli session to be in line-by-line mode. - Ignore stdin when it looks something like /dev/null. - Skip NUL bytes received from VPP. VPP CLI ------- - Detect "non-interactive" terminal types and set session parameters accordingly. - Add an "interactive" flag that controls whether the welcome banner and CLI prompt are sent. - Detect if telnet options processing switched us into line mode and act accordingly for the rest of the current input buffer. This was causing the command string to be echoed by the CLI editor code. - For non-interactive sessions, send a NUL byte after the input buffer has been processed. This is because vppctl depends on seeing traffic before it will try to close the session; a command with no output would cause it to hang. NUL bytes are ignored by all decent terminals, but we have vppctl strip them out anyway. - Prevent certain commands from running in non-interactive sessions since they manipulate interactive-related features. - For interactive sessions, quench the prompt that prints on VPP shutdown. - Detect and handle socket errors in the CLI; sessions were leaking. - Pevent SIGPIPE from ever being raised; handle EPIPE instead. We don't need VPP to die just because a socket closed just before we try to write to it! - Add a command to dump a list of current CLI sessions; mostly this was to detect session leakage, but it may have some general utility.
