2016-04-28Track number of ethernet vlans in a frameChris Luke9-9/+84
Adds flags to the packet buffer to track the number of VLANs in the current Ethernet frame. We use two bits to signify 0, 1 or 2 VLANs. The value 3 signififies an unknown quantity of VLANs, which includes "three or more" which is not widely supported. We place the bits in the vlib_buffer section; that is not the opaque section, so that all subordinate nodes can use it. For background, see the discussion thread at https://lists.fd.io/pipermail/vpp-dev/2016-March/000354.html The helper macro ethernet_buffer_header_size(buffer) uses these bits stored in "buffer" to calculate the Ethernet header size. The macro ethernet_buffer_set_vlan_count(buffer, count) sets the appropriate bit values based on the number in "count". By current frame we are referring to the case where a packet that arrives from the wire is carrying an encapsulated Ethernet packet. Once decapsulated that inner packet becomes the current frame. There are two places where this value is set; For most Ethernet frames this will be in the "ethernet-input" node when that node parses the Ethernet header. The second place is whenever vnet_update_l2_len() is used to update the layer 2 opaque data. Typically this function is used by nodes just before they send a packet into l2-input. These bits are zeroed in vlib_buffer_init_for_free_list() meaning that wherever the buffer comes from they have a reasonable value (eg, if ip4/ip6 generates the packet.) Primarily this VLAN counter is used by nodes below "ethernet- input" and "l2-input" to determine where the start of the current Ethernet header is. There is opaque data set by "ethernet-input" storing the offset of the current Ethernet header but, since this is opaque, it's not usable by downstream nodes. Previously several nodes have made assumptions regarding the location of the Ethernet header, including that it is always at the start of the packet buffer (incorrect when we have encapsulated packets) or that it is exactly sizeof(ethernet_header_t) away (incorrect when we have VLAN tags.) One notable case where this functionality is required is in ip6_neighbor when it generates a response to a received neighbor soliciation request; it reuses the incoming Ethernet header in-situ and thus needs to reliably know where that header begins. Also, at the suggestion of Dave Barach, this patch removes definition of HGSHM bits in the buffer flags since they are unused and unlikely to ever be.

2016-04-27CLI output pagerChris Luke3-85/+744
Buffers output from CLI commands as it arrives and allows the terminal to view this buffer one page at a time. - View of the buffer is moved with space/enter/up/down/page-up/page-down/ home/end. - At the end of the CLI command if less than one page of output was generated then the pager is not engaged. - 'q' to quit the pager, or scroll off the bottom. - Pager prompt displays the current view aperture line numbers and total number of lines buffered. - Can be disabled at runtime with "no-cli-pager" in the unix configuration. - The number of lines that will be stored in the buffer is limited to prevent excessive memory use; this limit is configurable with "cli-pager-buffer-limit" in the unix configuration. - Both these options can also be set in the console with "set terminal pager [on|off] [limit <lines>]". Limitations: - Does not yet implement a search function. - Whilst the terminal size is detected and tracked, changing the terminal size when the pager is being used will not cause a redraw of the page. - Lines that wrap the right most column are not yet handled gracefully.

2016-04-27Debug/Telnet CLI enhancementsChris Luke2-222/+1063
A fairly comprehensive re-work of the built-in debug and telnet CLI to add various command line editing features and to add command history to the debug CLI. This may seem like a large change but a good amount of it is merely reworking the existing CLI code (which changed its indent level). The features this patch enables include: - Enable history in the debug CLI. - Put both stdin and telnet connections in char-by-char mode. - Echo from the server, not the client, for more control. - Add a mostly no-op but fairly complete Telnet protocol processor. - Perform control code parsing on the input byte stream to match strings of both control codes and ANSI/VT100 escape sequences. - Up/down keys scroll through the history (like ^P/^N). - Do CRLF output cooking (\n -> \r\n) for connections that need it. - Left/right cursor movements, insert/erase at cursor. - Home/end cursor jumps. - Jump left/right word at a time (Ctrl-left/right). - Negotiate the terminal type from Telnet clients. (well, the code doesn’t really negotiate, it demands it, but the client is led to believe it was a negotiation) - Read terminal type from TERM variable for the local debug CLI. - Delete from cursor to end of line (^K). Delete char-right (^D/Del). - Clear screen (^L) and repaint prompt/current command (on non-ANSI terminals it just newlines and repaints the line).

2016-04-26MTU: set interface mtu tapMohsin Kazmi5-33/+57
This patch introduces standard command line 'set interface mtu' for setting the MTU for tap devices. It allows user to set the mtu in between 68 to 65535 bytes aligned to what linux kernel supports for tun/tap devices. Right now tapcli set the same MTU size for each tap interface. But it should be set and configure to per interface rather than per tap instance. Change-Id: I81b7f3ad95ca56d585907ff8f51d9935a428e01b Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

This patch is more or less a port of I71f3ba0c8192 to IPv6. In practice it allows creating a route via a neighbor which is not resolved yet. It also adds static flag to IPv6 neighbor entries. And as Damjan suggested, it formalizes ip46_address_t by using the IPv4 embedded IPv6 address format.

2016-04-25Convert lisp-gpe encap to interface tx nodeFlorin Coras12-539/+950
With this change, one lisp-gpe interface is created per vrf/overlay tenant and its tx node is used as encapsulator (or tunnel ingress). For all intents and purposes, the tx node inherits all functions previously performed by the lisp-gpe-encap node and it maintains said node's position in lisp-gpe's data-path graph. Chiefly, this opens the possibility to chain interface features, like IPSec, transparently with LISP. Furthermore, it brings basic data plane support for vrfs and LISP instance-ids (or virtual network instances as per RFC7364). Other changes include improvements to lisp-gpe enable and disable sequences and corresponding API/VAT fixes.

2016-04-25Improve mechanism for using loopback interface as BVI for BDsJohn Lo7-82/+68
When loopback interface is configured as BVI, instead of changing its output node from loopN-output to l2-input, the loopN-output node is now kept while its next tx node is changed from ethernet-input to l2-input. The packet setup previously done in bvi_to_l2 as part of l2-input is now performed in the loop output node. This change adds an extra node in the BVI output path but provides the following improvements: 1. IP address/route created on loopback prior to it being configured as BVI will still work properly. The requirement to (re)configure IP/route on loopback after it is configured as BVI is removed. 2. The output stats for loopback interfaces are always provided irrespective of their BVI configuration. 3. The loopback-BVI output stats can be batch updated outside the packet loop in output node, instead of per packet update in l2-input node, making l2-input node more efficient for BVI packets. 4. Restore original node property as implemented in node.c function vlib_node_add_next_with_slot() where next node indices stored in next slots of each node will remain unique. 5. Packet trace for BVI output includes loopN output node which provides useful packet data. Change-Id: I7f5bc72ef953a367363a179088210596881f9e73 Signed-off-by: John Lo <loj@cisco.com>

2016-04-22Add a vpp_restart commandDave Barach4-5/+250
vpp_restart solves the problem of restarting vpp and not exiting until the new vpp instance is sufficiently established to allow immediate binary API connections. The point is to avoid using arbitrary "sleep N" commands e.g. in CSIT shell scripts. We send SIGTERM to the current vpp process, and expect / depend on the process-monitor du jour to remove the vpp-api shared-memory segment. vpp_restart exits w/ status 0 if all is well, non-zero upon failure. In trying to make vpp_restart reliable, we discovered a recently-introduced heap corruption bug in .../dpdk/init.c, which caused vpp to crash on startup once every 20 times on a particular rig. If possible, we should check /var/log/syslog for evidence of unexpected multiple restarts during regression-testing.
