2017-10-06tuntap: Introduce per thread structure to suport multi-threadsSteven2-65/+99
https://gerrit.fd.io/r/#/c/8551/ decoupled the global variable, namely tm->iovecs from TX and RX. However, to support multi-threads, we have to eliminate the use of this global variable with per thread variable. I notice that rx_buffers must also be per thread variable. So, we introduce per thread struct to contain rx_buffers and iovecs. Each thread will find the per thread struct with thread_index.

2017-10-06Initial GENEVE TUNNEL implementation and tests.Marco Varlese16-2/+4265
Notes on this first implementation: * First version of the implementation does NOT support GENEVE OPTIONS HEADER: it isn't well understood what the purpose of the OPTIONS will be and/or what content would be placed in the variable option data; Once the IETF work will evolve and further information will be available it could be possible to modify the frame rewrite to contemplate the actual GENEVE OPTIONS.

2017-10-05dpdk/ipsec: rework plus improved cli commandsSergio Gonzalez Monroy14-1702/+2522
This patch reworks the DPDK ipsec implementation including the cryptodev management as well as replacing new cli commands for better usability. For the data path: - The dpdk-esp-encrypt-post node is not necessary anymore. - IPv4 packets in the decrypt path are sent to ip4-input-no-checksum instead of ip4-input. The DPDK cryptodev cli commands are replaced by the following new commands: - show dpdk crypto devices - show dpdk crypto placement [verbose] - set dpdk crypto placement (<device> <thread> | auto) - clear dpdk crypto placement <device> [<thread>] - show dpdk crypto pools Change-Id: I47324517ede82d3e6e0e9f9c71c1a3433714b27b Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>

2017-10-05Distributed Virtual Router SupportNeale Ranns13-109/+545
A distributed virtual router works by attmpeting to switch a packet, but on failing to find a local consumer (i.e. the packet is destined to a locally attached host) then the packet is sent unmodified 'upstream' to where the rest of the 'distributed' router is present. When L3 switching a packet this means the L2 header must not be modifed. This patch adds a 'l2-bridge' object to the L3 FIB which re-injects packets from the L3 path back into the L2 path - use with extreme caution.

2017-10-04dpdk: use vpp physmem allocator for dpdk buffersDamjan Marion2-63/+144
This allows us to have single contignuous allocation for DPDK buffers with single mmap FD, so buffer memory can be easily shared with diffrent process. As a consequence dpdk socket-mem is no longer in charge for allocating buffer memory, but still we need some space allocated for dpdk structures so default socket-mem is reduced form 256 to 64 MB. For a default of 16K buffers per numa node, physmem allocation is now 40MB, so basically this change reduces footprint from 256MB per socket to 48 (64 + 40).

2017-09-28tun/tap: Bad packets sent to kernel via tun/tap interfaceSteven2-22/+29
It was observed that under heavy traffic, VPP accidentally sent traffic with the wrong source and destination to the tun/tap interface. Traffic appears to be sent to the wrong direction. This problem is only seen when worker thread is configured. When worker thread is used, TX and RX may reside in different core. Yet both TX and RX threads are sharing the same global variable, namely iovecs without any mutex or memory barrier protection. This creates a race condition when heavy traffic is blasted to VPP, like 1000 pps. We could create a mutex or memory barrier to ensure atomic memory access. But why bother? It is a lot cheaper to just decouple the iovecs such that TX and RX have their own iovecs. Change-Id: I86a5a19bd8de54d54f32e1f0845bae6a81bbf686 Signed-off-by: Steven <sluong@cisco.com>

2017-09-21vppctl,cli: Improve non-interactive vppctl (VPP-944)Chris Luke2-89/+404
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.
