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>
2018-01-13Improve "show xxx tunnel" and "show int addr" outputJohn Lo1-23/+7
Improve "show xxx tunnel" output functions format_xxx_tunnel() for GRE, VXLAN, VXLAN-GPE, GENEVE and GTPU tunnels to make their output more consistent and provide better information. Improved the output of "show int addr" to make its info more consistent with tunnels and provide fib-index info.

2018-01-11api: remove transport specific code from handlersFlorin Coras1-10/+8
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>

2018-01-09GRE tunnel key should use fib_index instead of fib_id (VPP-1118)John Lo1-12/+1
Follow up fix - vl_api_gre_add_del_tunnel_t_handler should pass outer_fib_id from API message to vnet_gre_add_del_tunnel() and not convert it to fib_index, since vnet_gre_add_del_tunnel() already perform the lookup to get fib_index from fib_id.

2018-01-06GRE tunnel key should use fib_index instead of fib_id (VPP-1118)John Lo1-2/+11
The code path in src/vnet/gre/interface.c uses fib_id as a component to generate hash key for GRE tunnel. This should be fib_index as the GRE rx/decap data path will be using fib_index to generate the hash key to lookup the GRE tunnel.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-1/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-04-06Use thread local storage for thread indexDamjan Marion1-4/+4
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.

2017-04-05GRE over IPv6Ciara Loftus5-165/+533
Refactors the GRE node to work with both IPv4 and IPv6 transports. Note that this changes the binary configuration API to support both address families; each address uses the same memory for either address type and a flag to indicate which is in use. The CLI and VAT syntax remains unchanged; the code detects whether an IPv4 or an IPv6 address was given. Configuration examples: IPv4 CLI: create gre tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 CLI: create gre tunnel src 2620:124:9000::1 dst 2620:124:9000::2 IPv4 VAT: gre_add_del_tunnel src 192.168.1.1 dst 192.168.1.2 IPv6 VAT: gre_add_del_tunnel src 2620:124:9000::1 dst 2620:124:9000::2 Change-Id: Ica8ee775dc101047fb8cd41617ddc8fafc2741b0 Signed-off-by: Ciara Loftus <ciara.loftus@intel.com>

2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall1-10/+25
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.
