2016-05-19VPP-74 Fix signedness issue when terminal resizesChris Luke1-4/+9
When re-locating our current viewport into the pager buffer we need to verify that the new viewport is within the boundaries of the index. This condition is considered very rare, but nontheless the check is needed. Unfortunately I assumed the variable was signed; it is not, and the subtraction can in some cases cause the value to be negative. This is therefore a bonafide semantic error that may cause problems. This patch reworks the logic to avoid having to change it to be signed. Change-Id: I26f0747d38dcc43dd9c092d50f2489b122009e7b Signed-off-by: Chris Luke <chrisy@flirble.org>

2016-05-19Add support for multiple microarchitectures in single binaryDamjan Marion1-0/+27
* compiler -march= parameter is changed from native to corei7 so code is always genereted with instructions which are available on the Nehalem microarchitecture (up to SSE4.2) * compiler -mtune= parameter is added so code is optimized for corei7-avx which equals to Sandy Bridge microarchitecture * set of macros is added which allows run-time detection of available cpu instructions (e.g. clib_cpu_supports_avx()) * set of macros is added which allows us to clone graph node funcitons where cloned function is optmized for different microarchitecture Those macros are using following attributes: __attribute__((flatten)) __attribute__((target("arch=core-avx2))) I.e. If applied to foo_node_fn() macro will generate cloned functions foo_node_fn_avx2() and foo_node_fn_avx512() (future) It will also generate function void * foo_node_fn_multiarch_select() which detects available instruction set and returns pointer to the best matching function clone.

2016-05-16VPP-23 Re-work pager line collationv16.09-rc0Chris Luke1-88/+364
To better handle lines longer than the terminal width, re-work how the pager collates lines. We still store each output line in a vector or lines; additionally we index the start and end of displayable lines. The index then becomes the data to work out what to display. If the terminal is resized this index is rebuilt and the current page redisplayed and an attempt made to keep the current top-of-screen line in place.

2016-05-10VPP-46 Fix cut-and-paste in the debug CLIChris Luke1-38/+46
Since the move to line-mode the debug CLI was eating everything in the input_vector but only processing upto the first newline. Cut-and-paste type operations generally send a large block of input with multiple newlines and thus all but the very first line were simply ignored. This patch fixes that and also cleans up the difference between input_vector and current_command which in turn removes a lot of cruft from the keystroke parser. Previously current_command was just the character accumulator inside the char-by-char keystroke parser; complete commands were copied back to input_vector (overwriting anything already in there). Now, in char-by-char mode: - input_vector is the stream of incoming bytes yet to be processed - current_command is the accumulated characters of the next command to be executed; once newline is found, it is the complete command to be executed. In line mode: - input_vector and current_command are the same thing. Change-Id: I72d21f0f3508b413879071ab186a71cef1124a2b Signed-off-by: Chris Luke <chrisy@flirble.org>
2016-05-10Avoid clobbering output_function by concurrent CLI sessions doing ↵Andrew Yourtchenko4-17/+63
vlib_process_wait_for_event*. A problem is easily reproducible by taking the test harness code from the commit, and launching it in two terminals with some time overlap - the outputs will be sent to the wrong session. This commit moves the output_function and argument from a global structure into the process structure, thus the output_function is not clobbered anymore and each session gets only its own output. To ensure the callers can redirect the outputs to different destinations (e.g. the API calls via shared memory, etc.) the existing logic for vlib_cli_input() was retained. To avoid the magic numbers usage in the logic that does the page-alignment of the process stack, there are changes around the stack[] member of vlib_process_t. Also added a compile-time assert to ensure that the stack does indeed start on the page size multiple boundary.

2016-04-29VPP-27 Extend telnet protocol buffer guardChris Luke1-1/+1
With Telnet protocol overhead, the string "xterm-256color", which is the norm when the terminal is iTerm on a Mac, is longer than the 16 byte lookahead overflow guard in the Telnet protocol processor. This extends it to 24 bytes. This guard is designed to encourage the protocol processor to quit waiting for bytes indefinitely if those already in the buffer do not form a complete message. Whilst this is unlikely, extending the guard length would mean more bytes need to be received before it gives up.

2016-04-29Clean up per-thread mheap setup.Dave Barach1-22/+22
The stats thread was sharing the main mheap when we started at least one worker or I/O thread, but ran on its own mheap when we started 0 worker + io threads. Net of this change; if a VLIB_REGISTER_THREAD instance specifies a per-thread mheap, a per-thread mheap will be provided. Otherwise, threads share the main heap. The stats thread now uses the main heap. Simpler is better. Change-Id: I1fff0dd66ae8f7dfe44923f702734e2832b55b09 Signed-off-by: Dave Barach <dbarach@cisco.com>
2016-04-28Track number of ethernet vlans in a frameChris Luke1-2/+1
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).

2016-04-25Improve mechanism for using loopback interface as BVI for BDsJohn Lo1-4/+5
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>

This is complete rework of DPDK PCI initialization. It drops previous scheme where lspci/route/awk/sed are used and instead sysfs is solely used for discovering Ethernet PCI devices.

2016-04-14Change ARP and IP6-ND nodes to use interface-output node for outputJohn Lo1-5/+4
The current mechanism for setting up arp-input and ip6-discover-neighbor output nodes for interfaces using their interface link up/down callback function is inefficient and has potential timing issue, as observed for bonded interface. Now both nodes will setup output interface sw_if_index in the the sw_if_index[VLIB_TX] field of current packet buffer and then use the interface-ouput node to tx the packet. One side effect is that vlib_node_add_next_with_slot() needs to be modified to allow the same output node-id to be put at the specified slot, even if another slot contain that same node-id already exist. This requirement is caused by BVI support where all loopback interfaces set up as BVIs will have the same output node-id being l2-input while, for output-interface node, the output slot must match the hw_if_index of the interface.

Digging into the code, it turns out that if you do not configure cli-listen (Example: unix { cli-listen localhost:5002 } ) Then vpp is listening on the first available port starting at port 5000 anyway.

2016-03-16Add vpp native linux kernel AF_PACKET interface supportDamjan Marion2-0/+3
This is 1st drop of VPP native driver for linux AF_PACKET. New CLI: create host-interface name <host-if-name> [hw-addr <mac-address>] References: - Documentation/networking/packet_mmap.txt in the Linux kernel tree - man 7 packet Known issues: - attaching to linux bridge doesn't work - it is not expected to work in multicore setup Change-Id: I1cb1c3d305f349759e90e76e25696718b73bd73d Signed-off-by: Damjan Marion <damarion@cisco.com>
2016-03-03Copy flags when cloning next_framesNikhil P Rao1-0/+6
The VLIB_FRAME_NO_FREE_AFTER_DISPATCH flag is not preserved when cloning next_frames, as a result VLIB_FRAME_FREE_AFTER_DISPATCH can erroneously be set for a frame (see vlib_get_next_frame_internal()) Change-Id: Ice1d7ddcb807e1168aa0c157d9474be492d102c2 Signed-off-by: Nikhil P Rao <nikhil.rao@intel.com>

2016-03-02Remove spurious call to unix_physmem_init(...)Dave Barach1-2/+0
It turns out that unix_physmem_init(...) has been effectively disabled for a very long time. The vnet library supplied a weak symbol override for the vlib_app_physmem_init(...) which returned 1, meaning "do nothing." When we switched libvnet.a -> libvnet.so, the symbol override stopped working. Presto: unix_physmem_init(...) romps all over the data set up by vlib_buffer_pool_create(...), leading to ASSERT failures and/or bus errors, but only when using worker threads. Even then, the failure depended in some complicated way on library dynamic load order. We should remove .../vlib/vlib/unix/physmem.c entirely once we're sure we'll never want it back.
