2018-07-26Clean up dpdk plugin rx/tx pcap tracingDave Barach2-0/+6
Needed a spinlock to protect the data vector. Cleaned up debug cli so the output makes sense, and so that various parameters exist in one place. Removed a nonsense memset-to-zero which led to ultra-confusing results. Change-Id: I91cd14ce7fe84fd2eceab86e016b5ee001993be4 Signed-off-by: Dave Barach <dbarach@cisco.com>

2018-07-15VPP-1341: fix loopback interface graph arcsDave Barach1-1/+1
Remove broken special case from l2_input.c:set_int_l2_mode(), which turns out to confuse the graph dispatch engine. The loopback TX function needs to push packets to either ethernet-input or to l2-input, based on bridge / BVI configuration. Rather than overloading a single graph arc - and making vain attempts to reconfigure it - create both arcs and use the correct one. Rewrote the loopback tx function as an idosyncratic multi-arch quad/single loop fn. Change-Id: I15b56ce641d90a11e7b3c7d23859f40e168dd7b2 Signed-off-by: Dave Barach <dave@barachs.net>

2018-06-11MTU: Software interface / Per-protocol MTU supportOle Troan1-2/+1
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>

2018-01-23VPPAPIGEN: vppapigen replacement in Python PLY.Ole Troan1-1/+1
This is a version of the VPP API generator in Python PLY. It supports the existing language, and has a plugin architecture for generators. Currently C and JSON are supported. Changes: - vl_api_version to option version = "major.minor.patch" - enum support - Added error checking and reporting - import support (removed the C pre-processor) - services (tying request/reply together) Version: option version = "1.0.0"; Enum: enum colours { RED, BLUE = 50, }; define foo { vl_api_colours_t colours; }; Services: service { rpc foo returns foo_reply; rpc foo_dump returns stream foo_details; rpc want_stats returns want_stats_reply events ip4_counters, ip6_counters; }; Future planned features: - unions - bool, text - array support (including length) - proto3 output plugin - Refactor C/C++ generator as a plugin - Refactor Java generator as a plugin Change-Id: Ifa289966c790e1b1a8e2938a91e69331e3a58bdf Signed-off-by: Ole Troan <ot@cisco.com>
2018-01-11api: remove transport specific code from handlersFlorin Coras1-21/+21
This does not update api client code. In other words, if the client assumes the transport is shmem based, this patch does not change that. Furthermore, code that checks queue size, for tail dropping, is not updated. Done for the following apis: Plugins - acl - gtpu - memif - nat - pppoe VNET - bfd - bier - tapv2 - vhost user - dhcp - flow - geneve - ip - punt - ipsec/ipsec-gre - l2 - l2tp - lisp-cp/one-cp - lisp-gpe - map - mpls - policer - session - span - udp - tap - vxlan/vxlan-gpe - interface VPP - api/api.c OAM - oam_api.c Stats - stats.c Change-Id: I0e33ecefb2bdab0295698c0add948068a5a83345 Signed-off-by: Florin Coras <fcoras@cisco.com>

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.

2017-09-28tun/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>

2017-04-06Use thread local storage for thread indexDamjan Marion2-3/+3
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-17/+40
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.
