2017-10-04[aarch64] Fixes CLI crashes on dpaa2 platform.Christophe Fontaine5-5/+5

2017-10-03Repair vlib API socket serverDave Barach2-2/+2
- Teach vpp_api_test to send/receive API messages over sockets - Add memfd-based shared memory - Add api messages to create memfd-based shared memory segments - vpp_api_test supports both socket and shared memory segment connections - vpp_api_test pivot from socket to shared memory API messaging - add socket client support to libvlibclient.so - dead client reaper sends ping messages, container-friendly - dead client reaper falls back to kill (<pid>, 0) live checking if e.g. a python app goes silent for tens of seconds - handle ping messages in python client support code - teach show api ring about pairwise shared-memory segments - fix ip probing of already resolved destinations (VPP-998) We'll need this work to implement proper host-stack client isolation Change-Id: Ic23b65f75c854d0393d9a2e9d6b122a9551be769 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Dave Wallace <dwallacelf@gmail.com> Signed-off-by: Florin Coras <fcoras@cisco.com>

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.

2017-07-13VPP-895 multi-thread: fix vpp crash on show runtimeIgor Mikhailov (imichail)1-0/+29
In multi-threaded model (e.g. 1 main and 1 worker threads), after an ethernet interface is deleted (e.g. vhost-user interface), 'show runtime' command produces garbled output and sometimes leads to vpp crash. The reason is because vlib_node_rename() frees and reallocates node's 'n->name' vector, however the change is not propagated into copies of the node on worker threads.

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion5-44/+87
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.

2017-07-06unix: mkdir VPP_RUN_DIR before opening a socket in itChris Luke3-0/+30
Change https://gerrit.fd.io/r/#/c/7230/ added a Unix domain CLI socket in the default startup.conf; however unless you had previously run VPP with the DPDK plugin enabled the directory that it is created in. /run/vpp, would not exist and startup would fail. This directory is typically hosted in a tmpfs ramdisk and is thus ephemeral. This patch adds a function that attempts to mkdir VPP_RUN_DIR and uses it in both the DPDK plugin and the CLI code if the CLI socket is to be created in that directory.

2017-06-07VPP-873: fix vector expansion bug in dispatch_pending_nodeDave Barach1-13/+27
The main interior graph-node dispatch loop had a longstanding dangling vector element reference: for (i = 0; i < _vec_len (nm->pending_frames); i++) cpu_time_now = dispatch_pending_node (vm, nm->pending_frames + i, cpu_time_now); Passing a pointer to a vector element (nm->pending_frames + i) has considerable comedic potential if there's any chance that the vector could expand. dispatch_pending_node() calls dispatch_node(), and indirectly any interior graph node dispatch function. If that node happens to expand nm->pending_frames by filling in a new frame, nm->pending_frames can expand. After calling the node dispatch function, dispatch_node() does the following: nf = vec_elt_at_index (nm->next_frames, p->next_frame_index); If nm->pending_frames expands during dispatch function execution, p is a dangling reference to freed memory. By luck, the TCP stack managed to allocate a fresh frame which included "old-p," which caused p->next_frame_index to be filled with the new-frame poison pattern 0xfefefefe. This has been broken from day 1, summer 2007, first use of the third-generation vector processing library.

2017-05-22vhost: migrate to use device infra for worker thread assignment, rx-mode.Steven1-10/+1
and add adaptive mode support to receive queue - Migrate vhost to use device infra which does the interface/queue to worker thread assignment. - Retire vhost thread CLI and corresponding code which assigns interface/queue to worker thread. set interface placement should be used instead to customize the interface/queue to worker thread assignment. - Retire vhost interrupt/polling option when creating vhost-user interface. Instead, set interface rx-mode should be used. - Add code in vnet_device_input_unassign_thread to change the node state to interrupt if the last polling interface has left the worker thread for the device of the corresponding interface/queue. - Add adaptive mode support. The node state is set to interrupt initially. When the scheduler detects a burst of traffic, it switches the input node to polling. Then we inform the device that we don't need interrupt notification. When the traffic subsides, the scheduler switches the input node back to interrupt. Then we immediately tell the driver that we want interrupt notification again. - Remove some duplicate code in vlib/main.c Change-Id: Id19bb1b9e50e6521c6464f470f5825c26924d3a8 Signed-off-by: Steven <sluong@cisco.com>
