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>

2017-09-27VLAN support on host(af-packet) interface.Akshaya N1-3/+26
On host interface if a VLAN tagged packet is received, linux kernel removes the VLAN header from packet byte stream and adds metadata in tpacket2_hdr. This patch explicitely checks for the presense of VLAN metadata and adds it in VPP packet. Change-Id: I0ba35c1e98dbc008ce18d032f22f2717d610c1aa Signed-off-by: Akshaya N <akshaya@rtbrick.com>

2017-09-27acl-plugin: take 2 at VPP-991 fix, this time with a test case which verifies it.Andrew Yourtchenko3-3/+42
The replacement of [] with pool_elt_at_index and subsequent fixing it was incorrect - it was equivalent to &[], since it returns a pointer to the element. I've added VPP-993 previously to create a testcase, so this commit partially fulfills that one as well.

2017-09-25Fix sending GARP/NA on Bonded Interface Active/Backup Link Up/DownJohn Lo5-72/+101
For bonded interface in Active/Backup mode (mode 1), we need to send a GARP/NA packet, if IP address is present, on slave link state change to up or down to help with route convergence. The callback from DPDK happens in a separate thread so we need to make sure RPC call is used to signal the send_garp_na process in the main thread. Also need to fix DPDK polling so the slave links are not polled. Change-Id: If5fd8ea2d28c54dd28726ac403ad366386ce9651 Signed-off-by: John Lo <loj@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.
